[0026] Example

[0027] Reference Figures 1-4 This is an embodiment of the present invention, which provides a gearbox that is easy to clean and maintain, including:

[0028] The gearbox body 100 includes an upper mounting cover 101 and a lower mounting cover 102 that is snapped onto the upper mounting cover 101;

[0029] The fixing mechanism 200 includes an upper mounting base 201 that fits against the outer surface of the upper mounting cover 101, a threaded inner surface of the upper mounting base 201, a hollow threaded rod 202 that is threadedly connected to the threaded part of the inner surface of the upper mounting base 201, a hollow column 203 that is fixedly installed on the outer end face of the hollow threaded rod 202, a quick-release assembly 204 for disassembling the upper mounting cover 101 and the lower mounting cover 102, and a snap-fit ​​assembly 205 that is disposed on the outer surface of the lower mounting cover 102 and used in conjunction with the quick-release assembly 204.

[0030] The quick-release assembly 204 includes a pressure rod 204a slidably connected to the inner surface of the hollow threaded rod 202, a limiting block 204b fixedly installed on the outer end face of the pressure rod 204a, a spring 204c fixedly connected to the outer surface of the limiting block 204b, a release groove 204d formed on the inner surface of the hollow column 203, and a ball bearing 204e slidably connected to the inner surface of the release groove 204d.

[0031] Specifically, the snap-fit ​​assembly 205 includes a lower mounting base 205a that fits against the outer surface of the lower mounting cover 102, the inner surface of the lower mounting base 205a is threaded, a fixing sleeve 205b is threadedly connected to the thread of the lower mounting base 205a, and a locking groove 205c is formed on the inner surface of the fixing sleeve 205b.

[0032] The inner surfaces of the upper mounting base 201 and the lower mounting base 205a are both threaded, and are tightly connected to the hollow threaded rod 202 and the fixing sleeve 205b respectively by threaded connection, making them a whole structure. This ensures that the entire fixing mechanism 200 has sufficient stability and strength, and effectively prevents loosening or displacement during use.

[0033] Furthermore, the hollow column 203 penetrates the outer surfaces of the upper mounting cover 101 and the lower mounting cover 102, and the surfaces of the upper mounting cover 101 and the lower mounting cover 102 are provided with slots for use with the hollow column 203.

[0034] Furthermore, a protective sleeve is provided on the top of the hollow threaded rod 202, and the outer surface of the hollow column 203 slides in contact with the inner surface of the fixed sleeve 205b.

[0035] Furthermore, the pressure rod 204a penetrates the hollow threaded rod 202, and the outer surface of the pressure rod 204a slides in contact with the inner surface of the hollow threaded rod 202.

[0036] Preferably, the limiting block 204b is in contact with the surface of the ball 204e, and the other end of the spring 204c is fixedly connected to the inner surface of the hollow threaded rod 202.

[0037] It should be noted that the fixing sleeve 205b has a hollow cylindrical structure, and the locking groove 205c is in contact with the surface of the ball 204e.

[0038] When the gearbox body 100 needs cleaning or maintenance, the operator manually presses the pressure rod 204a, causing it to slide downwards along the hollow threaded rod 202. Since the pressure rod 204a is fixedly connected to the limiting block 204b, the limiting block 204b also moves downwards. As the limiting block 204b moves downwards, the spring 204c is compressed, generating a reverse elastic force. During this process, the limiting block 204b no longer applies pressure to the ball 204e, allowing it to move freely. Without the pressure of the limiting block 204b, the ball 204e can slide along the release groove 204d and disengage from the locking groove 205c of the fixed sleeve 205b, releasing the locked state and allowing the upper mounting cover 101 and the lower mounting cover 102 to separate.

[0039] When cleaning or maintaining the gearbox body 100 is required during use, the operator first manually presses the pressure rod 204a in the quick release assembly 204, causing it to slide downward along the inside of the hollow threaded rod 202. Since the pressure rod 204a is fixedly connected to the limit block 204b, the limit block 204b also moves downward accordingly. As the limiting block 204b moves downward, the spring 204c is compressed, generating a reverse elastic force. During this process, the limiting block 204b no longer applies pressure to the ball 204e, allowing it to move freely. Without the pressure of the limiting block 204b, the ball 204e can slide along the release groove 204d and disengage from the locking groove 205c of the fixed sleeve 205b, releasing the locked state. At this time, the mechanical locking relationship between the upper mounting cover 101 and the lower mounting cover 102 is released, allowing them to separate. After cleaning or maintenance, the upper mounting cover 101 and the lower mounting cover 102 are reinstalled. The upper and lower mounting covers are aligned and pushed together, allowing the ball 204e to enter the inlet of the fixed sleeve 205b. Then, the manual pressure on the pressure rod 204a is released, and the spring 204c begins to rebound, pushing the limiting block 204b upward. As the limit block 204b moves upward, it applies pressure to the ball 204e again, forcing the ball to slide along the release groove 204d and eventually engage with the locking groove 205c of the retaining sleeve 205b, returning to the initial locked state.

[0040] In summary, the quick-release assembly 204 and the snap-fit ​​assembly 205 work together to achieve fast and reliable disassembly and assembly. Simply press the lever 204a to disengage the ball 204e from the locking groove 205c, easily separating the upper mounting cover 101 and the lower mounting cover 102, simplifying the maintenance process and improving work efficiency.
