Abstract

The utility discloses a structural improvement of trampoline, which comprises a spring mattress, a protective mesh, and a plurality of groups of legs and safety guards, wherein, the legs are located under the spring mattress whose top is sheathed with a T-shaped three-way pipe sleeve welded under the outer rim of the spring mattress to support the spring mattress, the protective mesh and safety guard are arranged above the spring mattress, the safety guard takes a shape of arch, and two sides of the safety guard are flexibly connected with a fixed ring arranged on the protective mesh through a connection belt. The utility model has the advantages of stable structure, easy for assembling, tight connection and high safety performance. In addition, the legs and safety guard are connected with U-shaped ring, which may facilitate the installation of the legs and the safety guard and enhance the stability as well. The bottom of the protective mesh and the spring mattress may be linked together by adopting the mode of serial connection with binding rope with V-shaped head, which can reduce time spent by users for connecting the protective mesh and the spring mattress and can make the connection very firm.

Description

The structural improvement of trampoline

Technical field:

The utility model relates to entertainment for children facility technology field, especially relates to the trampoline that a kind of children of supplying jump and play in the above.

Background technology:

Current, along with the raising of expanding economy and living standards of the people, various recreational facilities are also progressively popularized, and trampoline is wherein a kind of.Common trampoline is mainly by sping mattress, catch net and many combined supports with organize guardrail more and constitute, and wherein, foot rest is arranged at the lower end of sping mattress, is used for the support spring mattress; Catch net and guardrail then are arranged at the upper end of sping mattress, are used to prevent that children from falling out outside the trampoline.From the trampoline of seeing in the market, its guardrail is a single straight pipe type structure, thin, the difficult overlap joint of profile, assembling difficulty, and the guardrail connection is not tight, the security poor performance; In addition, its catch net bottom is connected separately with each bar bandage of sping mattress, and is not only comparatively loaded down with trivial details, and connects also insecure.

The utility model content:

The purpose of this utility model is to provide at having the existing weak point of trampoline now a kind of structural improvement of trampoline, and structure is firm, connection is tight so that trampoline reaches, assembling is easy and the high effect of security performance.

For achieving the above object; trampoline of the present utility model includes sping mattress, catch net and many combined supports and organizes guardrail more; wherein; foot rest is positioned at the sping mattress lower end; its top be welded on the T tube socket of sping mattress lower end outer rim with the support spring mattress; catch net and guardrail then are arranged at the sping mattress upper end, and described guardrail is the arched door shape, and its both sides, top flexibly connect by connecting band and the retainer ring that is arranged on the catch net.

Described foot rest links to each other by the U-loop device with guardrail, and this U-loop device is made of U-shaped mortise lock, curved panel and the nut more than two groups, and U-shaped mortise lock double team is lived the bottom of foot rest top and guardrail, and its front end passes curved panel and cooperates with nut.

The rope of tying up that adopts front end to have oxycephaly between described catch net bottom and the sping mattress is serially connected.

The line of knitting of described catch net bottom is a vertical row type, and adjacent knitting has the gap between the line.

The beneficial effects of the utility model are: because guardrail adopts arched door formula structure; and its both sides, top link to each other with retainer ring on the catch net by connecting band; prop up the straight pipe type guardrail with traditional list and compare, it have structure firm, easy to assembly, connect closely and the high advantage of security performance.In addition, foot rest adopts the U-loop device to link to each other with guardrail, both can make things convenient for the installation of foot rest and guardrail, can increase its soundness again.And adopt front end to have the mode that rope be connected in series of tying up of oxycephaly between catch net bottom and the sping mattress, not only can reduce the user and connect institute's time spent on catch net and the sping mattress, and connection is very firm.

The specific embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in the accompanying drawing 1: trampoline of the present utility model includes sping mattress 10, catch net 20 and many combined supports 30 and organizes guardrail 40 more; wherein; foot rest 30 is positioned at sping mattress 10 lower ends; its top and sleeve pipe 11 sockets that are welded in sping mattress 10 lower end outer rims, 40 of catch net 20 and guardrails are arranged at sping mattress 10 upper ends.See shown in the accompanying drawing 2: for making guardrail 40 easy disassembly, the bend pipe 403 of every group of guardrail 40 by straight tube 401 that is positioned at two ends and L shaped pipe 402 and in the middle part of being positioned at pegged graft mutually and formed the arched door shape.

See that accompanying drawing 5-1 is to shown in the accompanying drawing 5-3: the suspension centre at guardrail 40 tops, L shaped pipe 402 upper ends that promptly are positioned at both sides flexibly connect by flat connecting band 41 and the square shape retainer ring 21 that is arranged on the catch net 20 respectively.

See that accompanying drawing 3 is with shown in the accompanying drawing 4: foot rest 30 links to each other by U-loop device 50 with guardrail 40, this U-loop device 50 is made of the U-shaped mortise lock 51 more than two groups, curved panel 52 and nut 53, U-shaped mortise lock 51 double teams are lived the bottom of foot rest 30 tops and guardrail 40, and its front end forms screw thread and passes curved panel 52 and cooperate with nut 53.During assembling, the T tube 11 of sping mattress 10 lower end outer rims is inserted in the groove 51 from top to bottom, in addition, a moving casing 501 that cooperates with straight tube 401 bottoms of guardrail 40 also can be set in the groove 51, after straight tube 401 bottoms of foot rest 30 tops and guardrail 40 both sides are inserted sleeve pipe 11 and moving casing 501 respectively, can screw fastening nut 53, make U-shaped mortise lock 51 sleeve pipes 11 and moving casing 501, like this, foot rest 30 and guardrail 40 promptly are fixed, be unlikely to rock, thus the firm degree of increase trampoline.

See shown in accompanying drawing 6-1 and the accompanying drawing 6-2: the rope 60 of tying up that has an oxycephaly 61 by front end between catch net 20 bottoms and the sping mattress 10 links to each other, and wherein, oxycephaly 61 is made by the harder PE material of quality and tied up the PP material that rope 60 then can adopt softness.Under the guiding of oxycephaly 61, tie up rope 60 staggered draw ring 12 and catch net 20 bottoms of passing sping mattress 10 each bandage front ends.In this way, the connection between catch net 20 and the sping mattress 10 is very convenient, and very firm.

For making things convenient for oxycephaly 61 and tying up rope 60 and pass, the line 201 of knitting of catch net 20 bottoms is vertical row type, and adjacent knitting between the line 201 has the gap.
