Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a polygonal limiting fixing sleeve. Background Art

[0002] In daily work and life, bolts and nuts are usually used for fixing. However, after the nuts are fixed, they often become loose, and the nuts cannot be protected, which affects the service life of the nuts. Therefore, we propose a polygonal limit fixing sleeve. Utility Model Content

[0003] The utility model aims to provide a polygonal limiting fixing sleeve, which has the advantages of conveniently fixing a nut to prevent rotation, protecting the nut and helping to prolong the service life.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A polygonal position-limiting fixing sleeve, based on a bolt and a nut, comprises a first fixing block and a second fixing block, wherein the first fixing block is a horizontally placed cylinder, a hexagonal through-hole is provided on the right side of the first fixing block, the second fixing block is a vertically placed hexagonal block, a first circular through-hole is fixedly provided on the right side of the second fixing block, a plurality of second circular through-holes are provided in a circumferential array on the side wall of the second fixing block, a third circular through-hole is provided on the side wall of the screw of the bolt, wherein two opposite second circular through-holes are provided with latches, and the latches pass through the third circular through-holes;

[0006] The first fixing block and the second fixing block are integrally formed.

[0007] The preferred solutions are as follows:

[0008] Preferably, the nut is located in the hexagonal through hole of the first fixing block, and the side wall of the nut abuts against the side wall of the hexagonal through hole of the first fixing block;

[0009] The distance from the left side to the right side of the first fixing block is four fifths of the distance from the left side to the right side of the nut, and the left side of the nut abuts against the right side of the second fixing block.

[0010] Preferably, the second fixing block is inscribed in the left side portion of the first fixing block.

[0011] In summary, the utility model has the following beneficial effects:

[0012] 1. Through the setting of the first fixing block, the first fixing block can be sleeved on the nut to protect the nut and initially limit the position;

[0013] 2. By setting the plurality of second circular through holes and the latch of the second fixed block, it is possible to achieve the effect of fixing the first fixed block and the second fixed block on the screw rod and positioning the nut without marking the hole angles of the nut and the second fixed block, and facilitating the correspondence between two opposite second circular through holes and the third circular through hole of the plurality of second circular through holes.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] The same components are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings.

[0020] A polygonal limiting fixing sleeve, such as Figure 1-Figure 3 As shown, based on the bolt and nut, it includes a first fixing block 1 and a second fixing block 2, the first fixing block 1 is a horizontally placed cylinder, the right side of the first fixing block 1 is provided with a hexagonal through hole, the second fixing block 2 is a vertically placed hexagonal block, the right side of the second fixing block 2 is fixed with a first circular through hole, the side wall of the second fixing block 2 is provided with a plurality of second circular through holes in a circumferential array, the side wall of the bolt is provided with a third circular through hole, wherein two opposite second circular through holes are provided with a latch 3, and the latch 3 passes through the third circular through hole;

[0021] The first fixing block 1 and the second fixing block 2 are integrally formed.

[0022] The latch pin 3 is a U-shaped split pin.

[0023] The nut is located in the hexagonal through hole of the first fixing block 1, and the side wall of the nut abuts against the side wall of the hexagonal through hole of the first fixing block 1;

[0024] The distance from the left side to the right side of the first fixing block 1 is four fifths of the distance from the left side to the right side of the nut, and the left side of the nut abuts against the right side of the second fixing block 2 .

[0025] Specific implementation process:

[0026] After the nut is fixed, the first fixing block 1 is inserted into the side of the screw rod close to the nut, and the first fixing block 1 is sleeved on the nut. Since the second fixing block 2 is integrally formed with the first fixing block 1, the second fixing block 2 is sleeved on the screw rod through the first circular through hole. A latch 3 is inserted into one of the second circular through holes of the second fixing block 2. The latch 3 passes through the third circular through hole of the screw rod and comes out from the second circular through hole on the opposite side. The latch 3 is bent to further complete the fixation of the second fixing block 2.

[0027] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
