Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment technology, specifically to an anti-reverse mechanism. Background Technology
[0002] There are many types of mechanical equipment. When mechanical equipment is running, some of its components or even itself can perform different forms of mechanical motion. The drive components inside the mechanical equipment can drive the equipment to run normally. Mechanical equipment consists of drive devices, speed change devices, transmission devices, working devices, braking devices, protective devices, lubrication systems, cooling systems, and other parts.
[0003] During the operation of mechanical equipment, if some mechanical equipment reverses, it will cause damage to the internal parts of the equipment. If the reversal of the mechanical equipment cannot be stopped in time, it will affect the normal use of the mechanical equipment and shorten its service life.
[0004] There is an urgent need for a mechanism to prevent reversal and address the technical deficiencies mentioned above. Summary of the Invention
[0005] The purpose of this invention is to provide a mechanism to prevent reverse rotation, thereby solving the problem of damage to parts caused by reverse rotation of mechanical drives as mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-reverse mechanism, comprising a drive shaft locking ring, a drive sprocket mounted on the left side of the drive shaft locking ring, a positioning pin provided at the front end of the drive sprocket, a spring locking ring fixedly connected to the outside of the positioning pin, a spring reserved groove provided on the outside of the drive sprocket, and a protective reserved sliding groove provided on the outside of the drive shaft locking ring.
[0007] Preferably, the positioning pin passes through the transmission sprocket and is embedded inside the protective reserved groove of the transmission shaft locking ring.
[0008] Preferably, the spring locking ring is fitted around the outside of the transmission sprocket, and the spring locking ring can be embedded inside the spring pre-reserved groove.
[0009] Preferably, the protective reserved groove is located on the outer ring of the drive shaft locking ring.
[0010] Preferably, the transmission sprocket is sleeved on the outside of the left side of the transmission shaft locking ring, and the transmission shaft locking ring is embedded inside the transmission sprocket.
[0011] Preferably, the inner diameter of the transmission sprocket is larger than the outer diameter of the transmission shaft locking ring.
[0012] Compared with the prior art, the beneficial effects of this utility model are: this anti-reverse mechanism not only achieves the function of avoiding damage to internal parts caused by reverse drive;
[0013] By incorporating a drive shaft locking ring, a spring locking ring, a locating pin, and a protective reserved slide groove, the drive shaft locking ring can be installed on the drive shaft of mechanical equipment. After the drive shaft locking ring is locked and fixed to the drive shaft, the drive sprocket is connected to the drive shaft locking ring. The locating pin on the drive sprocket is inserted into the interior of the drive shaft locking ring. When the drive sprocket rotates forward, the locating pin abuts against the edge of the protective reserved slide groove, thereby driving the drive shaft locking ring to rotate. When the drive sprocket rotates in reverse, the locating pin moves away from the edge of the protective reserved slide groove and slides inside the protective reserved slide groove, preventing the drive shaft locking ring from rotating. This structure avoids damage to parts caused by reverse rotation, thus improving the safety of mechanical equipment use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1: Please refer to Figure 1-4 A mechanism to prevent reverse rotation includes a drive shaft locking ring 1, a drive sprocket 4 installed on the left side of the drive shaft locking ring 1, a positioning pin 3 provided at the front end of the drive sprocket 4, a spring locking ring 2 fixedly connected to the outside of the positioning pin 3, a spring reserved groove 5 provided on the outside of the drive sprocket 4, and a protective reserved sliding groove 6 provided on the outside of the drive shaft locking ring 1.
[0021] The positioning pin 3 passes through the transmission sprocket 4 and is embedded in the protective reserved slide groove 6 of the transmission shaft locking ring 1. The protective reserved slide groove 6 is set on the outer ring of the transmission shaft locking ring 1.
[0022] Specifically, if Figure 1 and Figure 2 As shown, the drive shaft locking ring 1 can be installed on the drive shaft of the mechanical equipment. After the drive shaft locking ring 1 is locked and fixed to the drive shaft, the drive sprocket 4 is connected to the drive shaft locking ring 1. The positioning pin 3 on the drive sprocket 4 is inserted into the inside of the drive shaft locking ring 1. When the drive sprocket 4 rotates forward, the positioning pin 3 abuts against the edge of the protective reserved slide groove 6, and then drives the drive shaft locking ring 1 to rotate. When the drive sprocket 4 rotates in reverse, the positioning pin 3 moves away from the edge of the protective reserved slide groove 6 and slides inside the protective reserved slide groove 6, and cannot drive the drive shaft locking ring 1 to rotate. This structure avoids damage to parts caused by reverse rotation.
[0023] Example 2: The spring locking ring 2 is sleeved on the outside of the transmission sprocket 4, and the spring locking ring 2 can be embedded in the spring reserved groove 5;
[0024] Specifically, if Figure 1 and Figure 3 As shown, the spring locking ring 2 is fitted onto the transmission sprocket 4 to press the positioning pin 3, so that the positioning pin 3 is firmly locked inside the protective reserved groove 6 reserved in the transmission shaft locking ring 1, thereby enhancing the stability of the installation.
[0025] Example 3: The transmission sprocket 4 is fitted on the outside of the left side of the transmission shaft locking ring 1, and the transmission shaft locking ring 1 is embedded inside the transmission sprocket 4. The inner diameter of the transmission sprocket 4 is larger than the outer diameter of the transmission shaft locking ring 1.
[0026] Specifically, if Figure 1 and Figure 4 As shown, the transmission sprocket 4 is sleeved with the transmission shaft locking ring 1. The cooperation between the transmission shaft locking ring 1 and the transmission sprocket 4 can prevent damage to the equipment when it reverses.
[0027] Working principle: In use, the transmission shaft locking ring 1 can be installed on the drive shaft of the mechanical equipment. After the transmission shaft locking ring 1 is locked and fixed to the drive shaft, the transmission sprocket 4 is connected to the transmission shaft locking ring 1. The positioning pin 3 on the transmission sprocket 4 is inserted into the inside of the transmission shaft locking ring 1. When the transmission sprocket 4 rotates forward, the positioning pin 3 abuts against the edge of the protective reserved slide groove 6, and then drives the transmission shaft locking ring 1 to rotate. When the transmission sprocket 4 rotates in reverse, the positioning pin 3 moves away from the edge of the protective reserved slide groove 6 and slides inside the protective reserved slide groove 6, and cannot drive the transmission shaft locking ring 1 to rotate. This structure avoids damage to parts caused by reverse rotation.
[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
