Description

Anti-skid square sleeve chain wheel of electric vehicle

Technical Field

The utility model relates to a technical field of electric motor car chain wheel, specificly relate to an electric motor car antiskid side cover chain wheel.

Background

Some electric motor cars in the existing market still have pedals, and axis, chain wheel and square sleeve are the important component parts that realize pedal, but chain wheel among the prior art is connected with the square sleeve and is firm inadequately, and easy the slip, and then influences the pedal function of electric motor car.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides an electric motor car antiskid side cover chain wheel to it is firm inadequately to solve chain wheel and side cover and be connected, easy gliding problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an anti-skid square sleeve toothed disc of an electric vehicle comprises a square sleeve, a toothed disc and a middle shaft, wherein a boss is fixedly arranged at one end of the square sleeve, a clamping block is arranged at the edge of the boss, a socket is arranged in the middle of the toothed disc, a clamping groove corresponding to the clamping block is arranged at the edge of the socket, the boss is inserted into the socket, and the clamping block is positioned in the clamping groove;

the square sleeve is sleeved on the middle shaft, and the square sleeve and the middle shaft are detachably connected.

Preferably, the middle part of the square sleeve is provided with a jack, and two sides of the square sleeve are provided with pin holes; the middle shaft penetrates through the jack, and a bolt is arranged in the pin hole.

Preferably, the edge of the socket is uniformly provided with a plurality of convex keys.

The utility model has the advantages that: the utility model discloses an anti-skidding square sleeve chain wheel of electric motor car, reasonable in design, high durability and convenient use, through set up the fixture block at the boss edge, the socket edge of chain wheel sets up draw-in groove and convex key, after the boss gets into the socket, make the fixture block card go into in the draw-in groove, convex key and boss outer wall offset, avoid producing between boss and the chain wheel and slide, it is more firm to connect, rethread external force extrusion boss and fixture block, make the two atress take place to warp to the periphery, more step strengthened being connected between boss and the chain wheel like this, avoid droing, make the security higher.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-5, an anti-skid square toothed disc for an electric vehicle comprises a square sleeve 1, a toothed disc 2 and a middle shaft 3, wherein a boss 4 is fixedly arranged at one end of the square sleeve 1, a clamping block 5 is arranged at the edge of the boss 4, a socket 6 is arranged in the middle of the toothed disc 2, a clamping groove 7 corresponding to the clamping block 5 is arranged at the edge of the socket 6, the boss 4 is inserted into the socket 6, and the clamping block 5 is positioned in the clamping groove 7; the edge of socket 6 evenly is equipped with a plurality of convex keys 11, and after boss 4 got into socket 6, fixture block 5 blocked in draw-in groove 7, convex key 11 offseted with 4 outer walls of boss, has avoided producing between boss 4 and the chain wheel 2 and has slided, makes it connect more firmly, and the security is higher. The lug boss 4 and the fixture block 5 can deform towards the outer periphery under stress, and the connection between the lug boss and the toothed disc is further reinforced.

Furthermore, the middle part of the square sleeve 1 is provided with a jack 8, and two sides are provided with pin holes 9; the middle shaft 3 penetrates through the jack 8, the bolt 10 is installed in the pin hole 9 and used for fixing the square sleeve 1 and the middle shaft 3, and the bolt 10 is installed or taken out to complete connection or disassembly of the square sleeve 1 and the middle shaft 3, so that the square sleeve is convenient and quick.

The installation process of the present embodiment: the boss 4 is inserted into the socket 6, the fixture block 5 is positioned in the clamping groove 7, the convex key 11 at the edge of the socket 6 is abutted against the outer wall of the boss 4, and the boss 4 and the fixture block 5 are extruded by external force to be stressed to deform towards the outer periphery, so that the connection between the boss 4 and the chain wheel 2 is further reinforced, and the falling off is avoided; then the square sleeve 1 is sleeved on the middle shaft 3, and the bolt 10 is arranged, so that the electric bicycle can be installed on an electric bicycle for use.
