[0022] The following further describes the utility model in conjunction with specific embodiments and the drawings.

[0023] As Figures 1 to 8 shown, a hoisting power supply shell structure includes a detachable top cover 1 and a base 2. Plug-in slots 3 are provided around the bottom of the top cover 1, and plug-in strips 4 matching the plug-in slots 3 are correspondingly provided on the top of the base 2. The top cover 1 and the base 2 are positioned and matched by inserting the plug-in strips 4 into the plug-in slots 3. Screw seats 5 with connection holes are correspondingly provided in the top cover 1 and the base 2. Screws are installed vertically upward from the bottom of the base 2 to connect the two screw seats 5, thereby realizing the connection and fixation of the top cover 1 and the base 2.

[0024] A power supply (not shown in the figure) is fixedly installed at the central position inside the base 2. A plurality of heat dissipation holes 6 are formed at the bottom of the base 2. The heat dissipation holes 6 are trapezoidal holes. A shielding portion 7 extends from the top of the heat dissipation hole 6. The shielding portion 7 is L-shaped. One end thereof is connected to the inner bottom surface of the base 2, and there is a gap between the other end and the inner bottom surface of the base 2. The size of the heat dissipation hole 6 gradually decreases from bottom to top. And due to the existence of the shielding portion 7, it can effectively prevent students from using long strip-shaped items such as pens to extend into the housing through the heat dissipation hole 6 to touch the power supply, preventing the power supply from being damaged artificially.

[0025] In this embodiment, L-shaped shielding plates 8 are provided at the four corners of the power supply corresponding to the inner bottom surface of the base 2. The heat dissipation holes 6 are correspondingly arranged with the shielding plates 8. This structural design can further protect the power supply, avoid the power supply from being damaged, and also avoid production safety accidents related to electricity.

[0026] In another embodiment of the present invention, an external connection hole 9 is formed in the side wall of the base 2. A fixing seat 10 is provided at the inner bottom of the base 2 corresponding to the external connection hole 9. The fixing seat 10 includes a side plate 101 and a back plate 102. The two sides of the back plate 102 are vertically connected to the side plate 101 to enclose an installation cavity in a rectangular structure. One side of the installation cavity facing the external connection hole 9 is open. Three reinforcing ribs 11 are arranged in parallel at the bottom of the installation cavity. A connecting portion 103 with a threaded hole is provided on the outer side wall of the side plate 101.

[0027] The top surface of the reinforcing rib 11 is a horizontal plane, and the top surfaces of the three reinforcing ribs 11 are located on the same horizontal plane.

[0028] When installing connection devices in the hoisting power supply for connecting with other external devices, the existing technology is to design an installation shell, then insert the connection devices into the installation shell, and then place it in the base corresponding to the external connection hole. Through the cooperation of the top cover and the base, the installation shell is fixed inside the hoisting power supply housing. This method has the problem that the connection devices are not stably installed and are prone to shaking.

[0029] In this embodiment, the connection devices can be inserted into the fixing seat 10. A cover plate can be connected through the connecting portion 103 at the top of the fixing seat 10 to firmly limit the connection devices in the installation cavity.

[0030] In another embodiment of the present invention, a weak current hole 12 is provided on the side wall of the base 2. A boss 13 is provided on the inner wall of the weak current hole 12. A through hole 14 coaxial with the weak current hole 12 is formed on the boss 13, and the aperture of the through hole 14 is smaller than the aperture of the weak current hole 12. Grooves 15 communicating with the through hole 14 are correspondingly formed above and below the boss 13. This structural design makes the weak current hole a stepped hole, and a notch 16 is formed at the upper end and the lower end of the stepped hole.

[0031] In the prior art, the weak current hole is a circular through hole and the installation is not stable. In this embodiment, the weak current wire passes through the weak current hole 12. A clamping plate 17 is installed outside the weak current hole 12. A wire hole 18 for the weak current wire to pass through is correspondingly formed on the clamping plate 17. A flange 19 matching the weak current hole is arranged on the edge of the clamping plate 17. A clamping hook 20 is also arranged on the clamping plate 17. When the clamping plate 17 is inserted into the weak current hole 12, the clamping hook 20 is clamped at the notch 16 position, so that the weak current wire can be fixed very stably.

[0032] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
