Referring to fig. 1-5, the present invention relates to a stop device for a sliding block of an oil cylinder,

the oil cylinder 1 is used as a power source to push the shovel base 2 to move up and down, and the sliding block insert 6 is controlled to move by controlling the sliding block to move transversely on the inclined surface.

The oil cylinder 1 is provided with a driving shaft 101, and the end part of the driving shaft 101 is provided with a stop block;

the top surface of the shovel machine 2 is correspondingly provided with a first sliding groove 201, the other first sliding grooves 201 penetrate through the inclined surface adjacent to the top surface, the corresponding first sliding grooves 201 are inverted T-shaped grooves, and the stop blocks are in sliding fit with the bottoms of the T-shaped grooves.

Shovel machine 2 has top surface and inclined plane, and wherein top surface and inclined plane are the looks proximal surface, and the top surface is towards hydro-cylinder 1, and first spout 201 has been seted up towards first slider 4 to the inclined plane on the concrete top surface, and the tip sliding fit of drive shaft 101 is in first spout 201, passes through first spout 201 connection hydro-cylinder 1 promptly, and the edge on inclined plane is equipped with second spout 202 along the incline direction.

The retaining block 3 is preferably a trapezoidal plate, the retaining block 3 is provided with a pair of retaining blocks and is respectively fixed on two side surfaces of the shovel machine 2, the retaining block 3 is provided with an inclined sliding surface 302 and a thrust surface 301, and the inclined sliding surface 302 is aligned with the inclined groove edge of the second sliding groove 202.

First slider 4, first slider 4 have a pair of cardboard 402, and when cardboard 402 cooperateed at stopping block 3, "L" type cardboard supported in stopping block 3, had the thrust angle 401 that cooperation inclined sliding surface 302 and thrust surface 301 constitute the contained angle on the conflict face of cardboard 402, and first slider 4 moves along the inclined plane.

Preferably, the clamping plate 402 is an "L" shaped clamping plate, the "L" shaped clamping plate is fastened to the second sliding groove 202, the retaining block 3 has a surface which is in the same direction as the inclined surface, the surface is attached to the inclined surface in a sliding manner, and the surface is located between the two clamping plates 402.
