AI Technical Summary
The lack of an external anti-jump clamping device on the chain during transmission causes it to jump continuously and easily fall off, affecting the riding experience.
Design an automatic anti-jump clamping device for a crane chain, comprising a combination structure of a protective shell, a support shaft, a buffer wheel, screws, a mounting clamp, a bracket, a reinforcing sleeve, and bolts. Through the cooperation of these components, the chain can be limited and fixed.
This effectively prevents the chain from detaching from the gear sprocket surface, improving the chain's stability during transmission and ensuring smooth riding.

[0006] Further, the upper surface of the shell is fixedly connected with fixed frame, the end of fixed frame away from shell is fixedly connected with reinforcing sleeve.
[0007] Further, the inside of reinforcing sleeve is screw-connected with bolt.
[0008] Further, the number of fixed frame is two, two fixed frames are symmetrically arranged with the central axis of reinforcing sleeve.
[0009] The utility model provides a kind of vehicle chain automatic anti -jump compression device. It has the following beneficial effects:
[0010] The automatic anti-springing pressing device for the bicycle chain is characterized by the cooperation of the shell, the supporting shaft and the buffer wheel, which limits the chain from the outside, avoids the chain from jumping off the gear plate surface, and is easy to install on the vehicle through the mutual combination of the screw, the mounting hoop, the support, the reinforcing sleeve, the fixing frame and the bolt. BRIEF DESCRIPTION OF DRAWINGS
[0011] Fig. 1 It is a structural schematic view of the utility model;
[0012] Fig. 2 It is a structural front view of the utility model.
[0013] Among them, 1 shell, 2 supporting shaft, 3 buffer wheel, 4 screw, 5 mounting hoop, 6 support, 7 reinforcing sleeve, 8 fixing frame, 9 bolt. DETAILED DESCRIPTION
[0014] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0015] As shown in the figure, Figs. 1-2 The utility model embodiment provides an automatic anti-springing pressing device for bicycle chain, including shell 1, the upper surface of shell 1 is fixedly connected with fixing frame 8, the end away from shell 1 of fixing frame 8 is fixedly connected with reinforcing sleeve 7, the inside of reinforcing sleeve 7 is screw connected with bolt 9, the number of fixing frame 8 is two, two fixing frame 8 is symmetrically arranged with the central axis of reinforcing sleeve 7, the inner wall of shell 1 is fixedly connected with supporting shaft 2, the surface of supporting shaft 2 is sleeved with buffer wheel 3, the left side of shell 1 is fixedly connected with support 6, the end away from shell 1 of support 6 is fixedly connected with mounting hoop 5, the inside of mounting hoop 5 is screw connected with screw 4, the number of buffer wheel 3 is five, five buffer wheel 3 is dispersedly arranged.
[0016] Working principle: the shell 1 is sleeved on the outside of the gear plate and the chain, the mounting hoop 5 and the reinforcing sleeve 7 are all abutted on the vehicle frame, then the screw 4 and the bolt 9 are all screwed into the hole in the vehicle frame, thereby completing the installation of the shell 1, in the process of riding the vehicle, the chain will jump under the transmission condition, once the chain jumps, it will contact the buffer wheel 3 and make the buffer wheel 3 rotate on the surface of the supporting shaft 2, thereby avoiding the chain from the gear plate surface under the condition of reducing friction.
