Abstract
The utility model discloses a pin joint piece which comprises a connection pipe with at least one opened end, an axial strip-shaped hole is arranged in the connection pipe, an elastic clamp is arranged in the connection pipe and is provided with an arch-shaped elastic clamping section that is embedded in the strip-shaped hole and the top of the elastic clamping section is extended out of the strip-shaped hole; and a radial through hole is arranged at one end of the connection pipe and is internally provided with a pull ring. The pin joint piece has a simple structure, can be conveniently disassembled by inserting or extracting forcibly when being used, can be used for splicing at the connection of pipe fittings such as a bouncing bed and the like; and the elastic fastener design of the pin joint piece can not fall off easily, therefore, the use safety is high.
Description
Technical field
The utility model relates to the link at a kind of pipe fitting joint place, particularly a kind ofly is plugged on two pin joint spares between the pipe fitting.
Background technique
At the pipe fitting and the pipe fitting joint place of trampoline etc., connecting means commonly used now is that screw connects, and screw connects instruments such as needing spanner, dismounting comparatively bothers, in the particularly long-time process of using, the screw thread of screw is worn, is out of shape, cause screw can not or very difficult dismounting.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of pin joint spare of easy disassembly.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of pin joint spare, the connecting tube that comprises at least one end opening, described connecting tube is provided with axial bar hole, one elasticity card is installed in the described connecting tube, described elasticity card is provided with arc elasticity screens section, and described elasticity screens section is embedded in the described bar hole and stretch out outside the described bar hole at the top of described elasticity screens section; One end of described connecting tube is provided with radial direction through hole, and a draw ring is installed in the described through hole.
Described elasticity card is formed along intermediate portion doubling roughly by one section steel wire, and described bending section is that arc forms the section of opening; Described elasticity screens section is bent into arc formation by the position near steel cord end.
The beneficial effects of the utility model are: pin joint spare of the present utility model is simple in structure, only need firmly insert or extract during use and get final product, easy disassembly, can be used for being plugged on the joint of pipe fittings such as trampoline and pipe fitting, the Elastic buckle design of pin joint spare can not come off it easily, and the Security of use is also high.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a STRUCTURE DECOMPOSITION schematic representation of the present utility model;
Fig. 2 is user mode figure of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of pin joint spare, the connecting tube 1 that comprises at least one end opening, described connecting tube 1 is provided with axial bar hole 2, one elasticity card 3 is installed in the described connecting tube 1, described elasticity card 3 is provided with arc elasticity screens section 31, and described elasticity screens section 31 is embedded in the described bar hole 2 and stretch out outside the described bar hole 2 at the top of described elasticity screens section 31; One end of described connecting tube 1 is provided with radial direction through hole 4, and a draw ring 5 is installed in the described through hole 4.
Described elasticity card 3 is formed along intermediate portion doubling roughly by one section steel wire, and described bending section is that arc forms the section of opening 30; Described elasticity screens section 31 is bent into arc formation by the position near steel cord end.
As shown in Figure 2, end with pipe fitting B during connection stretches among the pipe fitting A, and the attachment hole of pipe fitting B and pipe fitting A is alignd, firmly pin joint spare is filled in the attachment hole of pipe fitting B and pipe fitting A then, in the process of filling in, the hole wall of attachment hole can push the elasticity screens section 31 of elasticity card, it is shunk in connecting tube 1, pass the attachment hole of pipe fitting B and pipe fitting A when elasticity screens section 31 after, elasticity screens section 31 elastic reactions open, and are stuck in the pipe fitting B, and elasticity screens section 31 blocking pin fittings withdraw from, the outer wall of pipe fitting A blocks draw ring 5 and prevents that pin joint spare from boring, catch draw ring firmly to extract during dismounting and get final product, easy disassembly can be used for being plugged on the joint of pipe fittings such as trampoline and pipe fitting, the Elastic buckle design of pin joint spare can not come off it easily, and the Security of use is also high.
