As a further description of the above technical solution:

and protective sleeves positioned outside the base wheels are welded at the positions, which are opposite to the two limiting annular blocks and positioned at the edges.

As a further description of the above technical solution:

the base wheels are two split structures symmetrically distributed along the radial direction and are connected through bolts.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses in, square race has been seted up to the exterior wall of foundation wheel, replace traditional V type groove, square inslot cover is equipped with two spacing annular pieces, radial sliding fit in square race is followed to two spacing annular pieces, the both sides wall elastic connection of spring and square race is passed through to its opposite side, the opposite side of two spacing annular pieces forms a V type groove structure, from this to the object in different line footpaths, axial subtend or the reverse slip in square race under the effect of spring are followed to two spacing annular pieces, with the direction that uses different line footpath objects.

2. The utility model discloses in, the base wheel constitutes for two components of a whole that can function independently structures of radial square symmetric distribution to through bolted connection, be divided into two the base wheel through disassembling the bolt from this, the change is demolishd to two spacing ring shape pieces to the convenience.

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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a novel carbide guide pulley, includes base wheel 1, still includes two split type spacing ring shape pieces 2, and square race 11 has been seted up to the exterior wall of base wheel 1, and two spacing ring shape piece 2 all overlap and establish in square race 11, and the opposite side forms a V type cross-section, through 3 elastic connection of spring between two lateral walls of two spacing ring shape pieces 2 and square race 11, two spacing ring shape piece 2 are in the direction of the suitable different line footpath object of square race 11 axial subtend or subtend relative slip.

Specifically, as shown in fig. 1, the opposite sides of the two stopper ring blocks 2, which are opposite to each other, are tapered, and this structure forms a V-shaped section.

Specifically, as shown in fig. 1, the sliding plates 21 which are axially distributed are welded on the inner surface wall of the limiting annular block 2, the sliding grooves 12 which are axially distributed are formed in the bottom surface wall of the square wheel groove 11, and the sliding plates 21 are located in the sliding grooves 12 and are in sliding fit, so that the limiting annular block 2 can be limited from rotating relative to the base wheel 1 in the circumferential direction, and the spring 3 is damaged.

Specifically, as shown in fig. 1 and 2, the number of the springs 3 is at least three and is uniformly distributed, so that the limiting circular block 2 is uniformly stressed.

Specifically, as shown in fig. 1 and 3, a protecting sleeve 22 located outside the base wheel 1 is welded to the opposite sides and the edge of the two limiting ring blocks 2, and the protecting sleeve 22 is used for preventing the wire body from entering a gap between the limiting ring blocks and the inner side wall of the square wheel groove 11.

Specifically, as shown in fig. 1, the base wheel 1 has two split structures symmetrically distributed along the radial direction, and is connected with the base wheel by bolts, so that the limiting ring block 2 can be conveniently detached after the base wheel 1 is detached.

The working principle is as follows: during the use, when the linear object of thick line footpath needs the conduction, the line body gets into the V type inslot that two spacing ring-shaped blocks 2 formed, and linear object receives the tensioning force, exerts a radial force to basic wheel 1, and two spacing ring-shaped blocks 2 axial reverse motion, and spring 3 compression is fit for the direction of different line bodies, and spring 3 stretches two spacing ring-shaped blocks 2 axial opposite direction motions otherwise, and through dismantling the bolt on the basic wheel 1 when spacing ring-shaped block 2 damages, basic wheel 1 divides into the components of a whole that can function independently of two symmetrical structure, can pull down the change with spacing ring-shaped block 2 from this.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
