[0039] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0040] Example 1

[0041] like Figures 1-6 As shown in this embodiment, a low-voltage servo motor is provided, including a motor body 1, a control box 2 is provided on the motor body 1, a fixing ring 9 is provided on the control box 2, the fixing ring 9 is fixedly sleeved on the motor body 1, a control module 3 is provided inside the control box 2, a plurality of wires 4 are provided on the control module 3, the plurality of wires 4 penetrate through the side wall of the control box 2 and extend to the outside, a lead hole is provided on the control box 2, and the wires 4 are led out from the lead hole to the outside of the control box 2; a box cover 5 is provided at the open end of the control box 2 to close the inner cavity of the control box 2, and a sealing gasket 8 is provided at the connection between the open end of the control box 2 and the box cover 5;

[0042] Among them, multiple insert rods 501 are fixed on both sides of the box cover 5. The insert rods 501 and the box cover 5 are made of plastic and are integrally formed. The insert rods 501 can undergo a certain degree of complete deformation. Each insert rod 501 has a hook 502 at its lower end. Multiple slots 201 that are compatible with the insert rods 501 are opened on the side wall of the control box 2, and the slots 201 have a groove 202 inside.

[0043] When the cover 5 is placed on the open end of the control box 2, the insertion rod 501 can be smoothly inserted into the slot 201 to achieve initial fixation.

[0044] Locking of hook 502 and slot 202: In addition to the engagement of the insertion rod 501 and the slot 201, each insertion rod 501 is also equipped with a hook 502 at its lower end. Correspondingly, a slot 202 is also provided inside the slot 201. When the insertion rod 501 is inserted into the slot 201, the hook 502 can automatically engage with the slot 202, thereby achieving a secure lock between the cover 5 and the control box 2.

[0045] Example 2

[0046] like Figures 3-4 As shown, based on Embodiment 1, in order to quickly remove the hook 502 from the inside of the slot 202 so as to quickly disassemble the box cover 5, a push rod 6 is fixed on the side wall of the control box 2. The side wall of the push rod 6 is provided with a groove 601 for easy insertion of the hand. A top block 7 is fixedly connected to the side wall of the push rod 6. The top block 7 is slidably connected inside the slot 202. Inclined walls are provided on the opposite side walls of the top block 7 and the hook 502.

[0047] Design of push rod 6 and groove 601: A push rod 6 is fixed on the side wall of the control box 2, and a groove 601 is provided on the side wall of the push rod 6 to facilitate finger insertion. This design allows the user to easily push the push rod 6 with their finger to perform subsequent operations.

[0048] The engagement of the top block 7 with the slot 202: A top block 7 is also fixedly connected to the side wall of the push rod 6. This top block 7 can slide inside the slot 202. When the cover 5 is placed on the control box 2, the top block 7 does not directly interfere with the locking state of the hook 502 and the slot 202.

[0049] The function of the inclined walls: Inclined walls are provided on the opposite side walls of the top block 7 and the latch 502. This means that when the top block 7 is pushed, it will slide along the inclined walls and gradually apply an outward force to the latch 502. This force is sufficient to disengage the latch 502 from the slot 202, thereby unlocking the fixation between the cover 5 and the control box 2.

[0050] Disassembly process: When the user needs to remove the cover 5, simply push the groove 601 on the push rod 6 with your finger and gently push it upwards, causing the top block 7 to slide along the slot 202, and the hook 502 will be pushed out of the slot 202 by the action of the inclined wall. Once the hook 502 is disengaged from the slot 202, the cover 5 can be easily removed from the control box 2.

[0051] Example 3

[0052] like Figure 2 , Figures 5-6 As shown, based on the above embodiment, in order to protect the connection between the wire 4 and the control module 3 and prevent it from being disconnected due to external force, the control box 2 is provided with a slide table 10. A lower slide seat 12 is slidably connected to the slide table 10 by a spring 11. An upper slide seat 13 is connected to the bottom of the box cover 5 by a diagonal pressure rod 14. The lower slide seat 12 and the upper slide seat 13 are both provided with clamping grooves 15 for clamping the wire 4 on their opposite surfaces.

[0053] A rubber pad 16 is laid on the surface of the clamping groove 15. When the wire 4 is clamped inside the clamping groove 15, the rubber pad 16 can protect the wire 4 and prevent the wire 4 from being damaged.

[0054] Multiple docking blocks 17 are fixed on the lower surface of the upper slide block 13, and docking grooves 18 adapted to the docking blocks 17 are opened on the upper surface of the lower slide block 12.

[0055] After the wire 4 is connected to the control module 3, the wire 4 will be in the clamping groove 15 of the lower sliding seat 12. Then, the cover 5 is installed. At this time, the upper sliding seat 13 on the cover 5 presses against the lower sliding seat 12, and the clamping groove 15 on the upper sliding seat 13 and the lower sliding seat 12 clamps the wire 4. At the same time, the docking block 17 is inserted into the docking groove 18. The cover 5 is pressed down, and after the cover 5 is in the closed state, the inclined pressure rod 14 will push the upper sliding seat 13 and the lower sliding seat 12 to move a distance towards the control module 3. At this time, the wire 4 between the control module 3 and the clamping groove 15 is in a relaxed state. Figure 2 As shown, when the wire 4 is pulled by an external force, the connection between the wire 4 and the control module 3 will not be affected by the pulling force, thus avoiding disconnection due to external force.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
