The top end surface of the cap is provided with a card slot matched with the upper support ring.

The protection net is fixed on the middle part of the guardrail with elastic bands with good elasticity.

Each tripod is connected to the ring-shaped iron pipe through a T-shaped three-way pipe, and at the top of some of the T-shaped three-way pipes, there are circular openings for inserting sleeves of the lower straight pipes of the support rods.

The outer cover of the spring mattress is provided with perforations at the position of the lower straight pipe of the corresponding support rod.

The outer edge ring of the center net of the spring mattress is provided with a plurality of triangular rings, and the upper hook of the triangular ring is provided with springs connected with the ring-shaped iron pipe at the upper end of the tripod, and the springs are staggered in forward and reverse ways.

The bottom of the protection net and the triangular ring on the outer edge of the central net are connected in series by a binding rope. The rope body of the binding rope is made of PP material, and the front end of the rope body is a pointed head made of PE material.

The weaving lines at the bottom of the protection net are arranged vertically, with a plurality of small holes therebetween.

The beneficial effect of the utility model is that: the support rod of the guardrail is a socket structure, and the support rod and the upper support ring are connected by a card slot, not only the structure is stable, but also the brace and hoisting operations during disassembly and assembly become easier. Very convenient.

Detailed ways:

The following descriptions are only preferred embodiments of the present utility model, and do not therefore limit the protection scope of the present utility model.

See shown in accompanying drawing 1: it comprises spring mattress 10, protective net 20, tripod 30 and guardrail 40, wherein, tripod 30 is positioned at spring mattress 10 lower ends, and protective net 20 and guardrail 40 are arranged on spring mattress 10 At the upper end, the guardrail 40 is composed of a plurality of support rods 41 ringed around the periphery of the spring mattress 10 and an upper support ring 42 located at the top of the protection net 20 . As shown in accompanying drawing 2: the support rod 41 is made up of upper and lower straight pipes 411 and 412 which are socketed with each other, wherein the top of the upper straight pipe 411 is provided with a connecting cap 413, and the top surface of the connecting cap 413 is provided with a The card slot 414 matched with the upper support ring 42 . In this way, the disassembly and assembly of the guardrail 41 will become very convenient, and the structure is also very stable. In addition, the protective net 20 can be fixed on the middle part of the guardrail 40 with an elastic band (not shown) with good elasticity, which not only increases the firmness of the protective net, but also buffers the impact force and enhances the safety factor.

See accompanying drawing 3 to shown in accompanying drawing 5: each tripod 30 links to each other with annular iron pipe 32 by T-shaped three-way pipe 50, at the top of wherein some T-shaped three-way pipes 50, is provided with the lower support bar 41. Section straight pipe 412 inserts the circular opening 51 of sleeve. Compared with the traditional welded structure, the user can directly insert the lower straight pipe of the support rod into the T-shaped tee pipe 50. The operation is very convenient, which not only saves the installation time of the user, but also is safe and firm.

See shown in accompanying drawing 1: on the outer cover 13 of spring mattress 10, the position of the lower section straight pipe 412 corresponding to the support rod 41 is provided with a perforation 131. Compared with the traditional closed jacket, this structure can facilitate the overlapping of the support bar and the T-shaped tee pipe 50, which is very convenient, fast and beautiful.

See accompanying drawing 6 and shown in accompanying drawing 7: the central net 11 outer edge ring of spring mattress 10 is provided with a plurality of triangular rings 111, and the upper hook of triangular ring 111 is provided with the spring that links to each other with the annular iron pipe 32 of tripod 30 upper ends 12. The rear end of the spring 12 is in the same direction as the hook of the pull ring 111 on the outside of the center net 11, but the hooks connected to the front end of the spring 12 and the ring-shaped iron pipe 32 are arranged in a staggered manner (i.e., forward and reverse). This structure can make the central net 11 have the advantages of firm structure, uniform force, vibration reduction and durability.

In addition, elastic ropes can be installed in the middle of the central net, the protection net and beside the four guardrails. Due to the elastic force of the elastic rope, the impact force of the child when jumping can be alleviated.

As shown in accompanying drawing 8: the bottom of the protective net 20 and the triangular ring 111 on the outer edge of the center net 11 are connected in series by a binding rope. The rope body 61 of the binding rope is made of soft PP material, and the front end of the rope body 61 It is a pointed head 62 made of hard PE material. Under the guidance of the pointed head 62, the binding ropes are interlaced through the triangular ring 111 and the bottom of the protective net 20, so that the connection between the protective net 20 and the spring mattress 10 is very convenient and very firm.

See shown in accompanying drawing 9: the weaving thread 21 at the bottom of the protective net 20 is a vertical row type, and there are a plurality of small holes 22 therebetween for the threading of the binding rope.
