AI Technical Summary
The existing track nuts are prone to loosening during the track walking, resulting in the insufficiency of the track plate and the chain rail links, which leads to damage.
A square lock nut of construction machinery track is designed. By setting a locking device on the nut main body, including an adjustment block and an extrusion block, the bolt squeezes the adjustment block to drive the extrusion block close to the main body connected to the nut main body, and ensures that the action plate comes into contact with other items through the insertion rod and the spring to prevent reverse rotation.
It improves the connection tightness between the nut and the installation body, reduces the risk of slack, enhances the stability of the device, prevents reverse rotation, and extends the service life of the track.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nuts, and particularly relates to a square locking nut for an engineering machinery crawler belt. Background Art
[0002] When the existing crawler belt nut is in use, during the process of the crawler belt running, the nut rotates in the loosening direction, so the nut and the bolt are prone to looseness, which will cause the connection between the crawler belt plate and the track link to be insecure, and further cause damage to the crawler belt plate and the track link during running. For this reason, we propose a square locking nut for an engineering machinery crawler belt. Summary of the Utility Model
[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a square locking nut for an engineering machinery crawler belt, which effectively solves the above problems.
[0004] To achieve the above object, the utility model provides the following technical solution: a square locking nut for an engineering machinery crawler belt, comprising a nut body, wherein cut surfaces are arranged at the four corners of the nut body, locking devices are arranged on the left and right sides of the nut body, the locking device comprises an adjusting block, an extrusion block is connected to the upper side of the adjusting block, chutes are arranged on the left and right sides of the nut body, the adjusting block is located inside the chute of the nut body, and bolts are connected to the left and right sides of the nut body.
[0005] Preferably, two groups of jacks are arranged on the lower side of the nut body, inserting rods are arranged in the jacks of the nut body, the lower sides of the two inserting rods are connected with an acting plate, and anti-slip lines are arranged on the lower side of the acting plate.
[0006] Preferably, two groups of springs are connected to the upper sides of the inserting rods, and the acting plate is located outside the springs.
[0007] Preferably, an auxiliary groove is arranged on the lower side of the nut body, and the upper sides of the springs are located inside the auxiliary groove on the lower side of the nut body.
[0008] Preferably, insertion holes matching the bolts are arranged at the opposite ends of the adjusting blocks on the left and right sides.
[0009] Preferably, a limiting plate is arranged on the lower side of the adjusting block, and a chute matching the limiting plate is arranged on the lower side of the nut body.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. By setting a locking device, the connection between the nut body and the installation body during use is made closer, reducing the risk of the nut body becoming loose. The adjusting block is squeezed by a bolt, and the squeezing block is driven by the adjusting block to approach the body connected to the nut body, and then the squeezing block is stuck on the outside of the installation body.
[0012] 2. By setting the acting plate to contact other objects, the phenomenon of the nut body rotating in the reverse direction is reduced. By setting a spring, the acting plate is always in contact with other fixing parts, thereby indirectly improving the stability of the device in use, ensuring that the lower side of the nut body is always in contact with other objects, and reducing the possibility of the nut body rotating and loosening in the reverse direction.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1-3, A square locking nut for an engineering machinery crawler, comprising a nut body 100. Cut surfaces are provided at the four corners of the nut body 100. Locking devices 200 are provided on both the left and right sides of the nut body 100. The locking device 200 includes an adjusting block 210. An extrusion block 220 is fixedly connected to the upper side of the adjusting block 210. Sliding grooves are provided on both the left and right sides of the nut body 100. The adjusting block 210 is located inside the sliding grooves of the nut body 100. Bolts 110 are screwed on both the left and right sides of the nut body 100. When the device is in use, the nut body 100 is installed at the position where it is needed, and then the bolts 110 are rotated. The adjusting block 210 is extruded by the bolts 110. The extrusion block 220 is driven by the adjusting block 210 to approach the main body connected to the nut body 100. Then, the extrusion block 220 is stuck on the outside of the installation main body, making the connection between the nut body 100 and the installation main body closer during the use of the nut body 100, and reducing the risk of the nut body 100 becoming loose.
[0021] Two groups of jacks are provided on the lower side of the nut body 100. Plug rods 300 are arranged inside the jacks of the nut body 100. A function plate 310 is fixedly connected to the lower sides of the two groups of plug rods 300. Anti-slip lines are provided on the lower side of the function plate 310. The plug rods 300 are inserted into the inside of the jacks, driving the function plate 310 to move to the lower side of the nut body 100. During the use of the device, the function plate 310 on the lower side of the nut body 100 contacts other objects, thereby reducing the phenomenon of the nut body 100 rotating in the reverse direction. Two groups of springs 320 are fixedly connected to the upper sides of the plug rods 300. The function plate 310 is located outside the springs 320. An auxiliary groove is provided on the lower side of the nut body 100. The upper sides of the springs 320 are located inside the auxiliary groove on the lower side of the nut body 100. By providing the springs 320, the function plate 310 is always in contact with other fixed parts, thereby indirectly improving the stability of the device during use, making the lower side of the nut body 100 always in contact with other objects, and reducing the possibility of the nut body 100 rotating and becoming loose in the reverse direction. Jacks matching the bolts 110 are provided at the opposite ends of the adjusting blocks 210 on both the left and right sides. By providing the jacks, the contact stability between the adjusting block 210 and the bolts 110 is improved. A limiting plate 211 is fixedly connected to the lower side of the adjusting block 210. A sliding groove matching the limiting plate 211 is provided on the lower side of the nut body 100. By providing the limiting plate 211, the adjusting block 210 is prevented from shaking during use, thereby improving the stability of the device during use.
