Detailed Description

In the description, numerous specific details are provided to provide a thorough understanding of embodiments of the utility model; one skilled in the art will recognize, however, that the utility model may be practiced without one or more of the specific details; in other instances, well-known details are not shown or described to avoid obscuring aspects of the utility model. The technical contents and detailed description of the present invention are described below with reference to the drawings:

the utility model provides a structure combining a pulley block and a strap plate, which is used for a strap A to be buckled and worn on a user, and mainly comprises a strap plate 10 and a pulley block 20, as shown in fig. 1 and 2.

The backing plate 10 is a metal member, such as a stainless steel sheet or an aluminum alloy plate, but the utility model is not limited thereto. A first connecting portion 11 is provided at the center of the strap plate 10. At least one through hole 12 is respectively arranged on the left side and the right side of the first connecting part 11, and each through hole 12 is used for buckling and fixing the braces A so as to be worn by a user.

The pulley block 20 mainly includes a base 21, a pulley 22, a shaft 23 and a side plate 24, wherein the base 21 includes a base 211 and a side plate 212 extending from the base 211. The shaft 23 sequentially passes through the side plate 212, the pulley 22 and the liftable side plate 24, so that the pulley 22 is rotatably disposed between the side plate 212 and the liftable side plate 24. The side plate 212 and the liftable side plate 24 are respectively formed with a

concave groove

212A, 241 at a side adjacent to the pulley 22. The recessed

grooves

212A and 241 receive both end surfaces of the pulley 22, respectively, and thus the rope B is prevented from being caught between the pulley 22 and the side plate 212 or the openable side plate 24. The base 211 is provided with a second connecting portion 211A, and the second connecting portion 211A is connected corresponding to the first connecting portion 11, so that the pulley block 20 can be fixed at the center of the strap plate 10.

Preferably, the pulley block and strap plate combination structure of the present invention further comprises a fixing member 30. The fixing element 30 passes through the first connecting portion 11 and then is fixed to the second connecting portion 211A, so as to fasten the strap plate 10 to the seat body 211 of the pulley block 20, but the utility model is not limited thereto, for example, the first connecting portion 11 and the second connecting portion 211A may be connected and fixed by snap, welding or screwing. In the embodiment, the fixing member 30 is a bolt, the first connecting portion 11 is a fixing hole, and the second connecting portion 211A is a screw hole, so that the bolt can pass through the fixing hole and be locked in the screw hole, and the head portion of the bolt can clamp the strap board 10.

Further, the pulley block 20 further includes a latch assembly 25. The base 211 has a receiving cavity 211B, the liftable side plate 24 has a positioning hole 242, and the latch assembly 25 is disposed in the receiving cavity 211B and can be moved into or out of the positioning hole 242, so that the liftable side plate 24 can be positioned by the latch assembly 25 and cannot rotate. Specifically, the latch assembly 25 includes a spring 251, a latch 252 and a positioning pin 253. The spring 251 is located inside the latch 252 and elastically pushes against the latch 252. The base 211 further has a through hole 211C communicating with the accommodating groove 211B, the latch 252 has a limiting groove 252A, and the positioning pin 253 passes through the through hole 211C and is accommodated in the limiting groove 252A, so that the latch 252 slides in the accommodating groove 211B and the positioning pin 253 limits the moving stroke of the latch 252. Referring to fig. 4 and 5, when the tenon 252 is pressed to slide toward the spring 251 and disengage from the positioning hole 242, the rotation of the liftable side plate 24 can be recovered, so that the rope B can be conveniently sleeved on the pulley 22 after the liftable side plate 24 is unscrewed. When the latch 252 is released, the latch 252 is automatically pushed back to the position by the elastic force of the spring 251.

Referring to fig. 1, 2 and 4, in the embodiment, the through holes 12 of the back belt plate 10 are elongated, and the number of the through holes 12 on the left and right sides is four, but the utility model is not limited thereto, and the shape and the number of the through holes 12 can be adjusted as required. Specifically, the four through holes 12 on either side of the strap board 10 may be divided into two lateral through holes 121 and two longitudinal through holes 122. The two longitudinal through holes 122 are vertically arranged in parallel, and the two transverse through holes 121 are vertically arranged at the upper and lower sides of the two longitudinal through holes 122. Therefore, the user can select to buckle the strap A into the inner longitudinal through hole 122 or the outer longitudinal through hole 122 according to the body shape of the user, and the upper and lower lateral through holes 121 can make the strap plate 10 be used in a vertically symmetrical manner. Please refer to fig. 6, which is a schematic view of a usage state of the pulley block and strap plate combination structure of the present invention, wherein a side strap a is fastened to an outer longitudinal through hole 122, and a rope B sleeved by a pulley 22 is located at the center of the strap plate 10, so that the rope B is not skewed during lifting and falling to cause rope jamming or single-side abrasion.

However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited by the above description, and all equivalent variations and modifications made by the claims of the present invention should also be covered by the protection scope of the present invention. The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
