Description

Technical Field

[0001] The utility model relates to the technical field of mechanical structures, and particularly relates to an electric motor with an insulation protection structure. Background Technique

[0002] During the installation process of the electric motor, the layout of the motor leads is an important issue that cannot be ignored. The leads of the motor are connected to other external electronic components through the wire outlet of the machine base to play their due roles in cooperation. When the motor leads pass through the wire outlet, in order to prevent direct contact between the leads themselves and the edge of the wire outlet of the machine shell, increasing the insulation risk of the leads to the ground, an insulation sheath is often sleeved around the wire outlet.

[0003] The existing insulation protection sleeves are mostly made of rubber and are usually stuck at the wire outlet of the front shell of the motor by relying on the toughness of the material. However, during the use of the motor, due to the relatively soft material of the insulation protection sleeve, when the wire is led out through the insulation protection sleeve, the protection sleeve is easily taken out by the wire, exposing the wire at the wire outlet and posing a risk of electric leakage. Content of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solution: an electric motor with an insulation protection structure, including a motor body, a connecting sleeve and a limiting inner tube;

[0005] The connecting sleeve is arranged at the bottom of the motor body. The connecting sleeve includes a blocking ring arranged in a circle on the outer wall of the connecting sleeve and a plurality of connecting teeth arranged at the top of the connecting sleeve. The blocking ring abuts against the motor body. The limiting inner tube is nested inside the connecting sleeve. The limiting inner tube includes guiding blocks arranged on both sides of the limiting inner tube and clamping blocks arranged at the upper and lower ends of the guiding blocks. The clamping blocks are in clamping connection with the connecting sleeve, and the limiting inner tube is slidably nested inside the connecting sleeve to fix the position of the connecting teeth.

[0006] By adopting the above technical solution, the connecting teeth arranged at the top of the connecting sleeve can be clamped and connected to the bottom of the motor body, and the position of the connecting teeth can be fixed by slidably nesting a limiting inner tube inside the connecting sleeve.

[0008] By adopting the above technical solution, the wire can extend from the wire outlet to the outside of the motor body.

[0009] Preferably, the materials of the connecting sleeve and the limiting inner tube are both PVC, which have good toughness and insulation properties.

[0010] By adopting the above technical solution, the connecting sleeve can be engaged with the wire outlet hole through the material deformation of the connecting sleeve.

[0011] Preferably, the connecting sleeve includes a blocking ring and connecting teeth. A plurality of the connecting teeth are rotationally symmetric about the axis of the connecting sleeve, and gaps are left between the plurality of connecting teeth. The connecting sleeve and the wire outlet hole form a sliding structure.

[0012] By adopting the above technical solution, the connecting sleeve can be connected to the wire outlet hole through sliding.

[0013] Preferably, the connecting sleeve includes guiding grooves opened on both sides of the connecting sleeve and clamping grooves opened inside the guiding grooves. There are two guiding grooves, and the two guiding grooves are rotationally symmetric about the axis of the connecting sleeve. The guiding grooves are L-shaped and are slidably connected to guiding blocks arranged on both sides of the limiting inner tube.

[0014] By adopting the above technical solution, the guiding blocks can slide inside the guiding grooves along the guiding grooves.

[0015] Preferably, the clamping block is embedded in the clamping groove and is engaged with it. The connecting sleeve and the limiting inner tube form a rotational connection.

[0016] By adopting the above technical solution, the clamping block can be embedded into the inside of the clamping groove by rotating the limiting inner tube, thereby fixing the position of the limiting inner tube.

[0017] Preferably, there are two guiding blocks, and the two guiding blocks are rotationally symmetric about the axis of the limiting inner tube. A plurality of conical anti-slip teeth are arranged on the outer side of the guiding blocks.

[0018] By adopting the above technical solution, it is beneficial to increase the friction between the hand of the operator and the guiding blocks.

[0019] Compared with the prior art, the beneficial effect of the present utility model is that by providing a connecting sleeve and a limiting inner tube, the connecting teeth arranged at the top of the connecting sleeve can be engaged with the bottom of the motor body, and by slidably nesting the limiting inner tube inside the connecting sleeve, the position of the connecting teeth can be fixed, so that the connecting sleeve is firmly fixed on the motor body, thereby protecting the wires inside the connecting sleeve.

The limiting inner tube 3 is slidably nested inside the connecting sleeve 2 to fix the position of the connecting teeth 202. By snap-connecting the connecting teeth 202 provided at the top of the connecting sleeve 2 to the bottom of the motor body 1 and sliding and nesting the limiting inner tube 3 inside the connecting sleeve 2, the position of the connecting teeth 202 is fixed.

[0031] Embodiment Two

[0032] Please refer to Figure 2 、 Figure 3 and Figure 4 The present utility model provides a technical solution: a motor with an insulation protection structure, including a motor body 1, a connecting sleeve 2, a blocking ring 201 and connecting teeth 202;

[0033] The material of the connecting sleeve 2 is PVC, which has good toughness and insulation. A number of connecting teeth 202 are rotationally symmetric about the axis of the connecting sleeve 2. There are gaps between the connecting teeth 202. The connecting sleeve 2 and the outlet hole 102 are of a sliding structure, allowing the connecting sleeve 2 to be connected to the outlet hole 102 by sliding. A number of connecting teeth 202 provided at the top will be snapped into the outlet hole 102 after the material deforms, so that the connecting sleeve 2 is fixed at the bottom of the front-end housing 101. Guide grooves 203 are opened on both sides of the connecting sleeve 2. There are two guide grooves 203, and the two guide grooves 203 are rotationally symmetric about the axis of the connecting sleeve 2. The guide grooves 203 are L-shaped and are slidably connected to the guide blocks 301 provided on both sides of the limiting inner tube 3. A clamping groove 204 is opened inside the guide grooves 203.

[0034] Embodiment Three

[0035] Please refer to Figure 3 、 Figure 4 and Figure 5, the present utility model provides a technical solution: a motor with an insulation protection structure, including a limiting inner tube 3, a guiding block 301 and a clamping block 303;

[0036] The material of the limiting inner tube 3 is PVC, which has good toughness and insulation. There are two guiding blocks 301. The two guiding blocks 301 are rotationally symmetric about the axis of the limiting inner tube 3. A number of conical anti-slip teeth 302 are arranged on the outer side of the guiding block 301, which can help improve the friction between the operator's hand and the guiding block 301. The guiding block 301 is slidably connected with the guiding groove 203, allowing the guiding block 301 to slide inside the guiding groove 203. The clamping blocks 303 arranged at the upper and lower ends of the guiding block 301 are snap-connected with the clamping grooves 204. After the guiding block 301 slides to the top in the guiding groove 203, the limiting inner tube 3 is rotated clockwise along the guiding groove 203, so that the clamping block 303 is embedded into the clamping groove 204 and snap-connected with it, thereby fixing the position of the limiting inner tube 3. The top of the limiting inner tube 3 will limit the inward deformation of the connecting clamping teeth 202, so that the connecting sleeve 2 can be firmly fixed at the bottom of the front housing 101.

[0037] Working principle: First, align the connecting clamping teeth 202 provided at the top of the connecting sleeve 2 with the wire outlet hole 102 opened at the bottom of the front housing 101, and push the connecting sleeve 2 so that a number of connecting clamping teeth 202 provided at its top will be snapped into the wire outlet hole 102 after the material deforms, so that the connecting sleeve 2 is fixed at the bottom of the front housing 101. Then, a limiting inner tube 3 is slidably nested inside the connecting sleeve 2. The operator pinches the two guiding blocks 301, allowing the guiding block 301 to slide inside the guiding groove 203. After the guiding block 301 slides to the top in the guiding groove 203, the limiting inner tube 3 is rotated clockwise along the guiding groove 203, so that the clamping block 303 is embedded into the clamping groove 204 and snap-connected with it, thereby fixing the position of the limiting inner tube 3. The top of the limiting inner tube 3 will limit the inward deformation of the connecting clamping teeth 202, so that the connecting sleeve 2 can be firmly fixed at the bottom of the front housing 101, thus protecting the wires inside the connecting sleeve. When sliding the guiding block 301, a number of conical anti-slip teeth 302 arranged on the outer side of the guiding block 301 can help improve the friction between the operator's hand and the guiding block 301.
