Description

Technical Field

[0001] This utility model relates to the field of actuator housing technology, and more specifically, to a waterproof and dustproof electric actuator housing. Background Technology

[0002] Actuators are an essential component of automatic control systems. Their function is to receive control signals from the controller, change the magnitude of the controlled medium, and maintain the controlled variable at the required value or within a certain range. Actuators can be classified into three main categories according to their energy source: pneumatic, hydraulic, and electric. The actuator housing is an indispensable part of the actuator, and its main function is for protection.

[0003] Among them, patent publication number CN214206072U discloses a waterproof and dustproof electric actuator housing, relating to the field of actuator technology. The housing includes an external rainproof structure on top, an internal dehumidification structure inside, and a ejector structure near the edge of the inner bottom wall. The external rainproof structure includes an arc-shaped electric telescopic rod, a fixed base, a rotating shaft, and a rainproof plate. This is a waterproof and dustproof electric actuator housing.

[0004] When in use, this structure, through the combination of an external rainproof structure and an internal dehumidification structure, can both prevent external water from entering the box and dissipate moisture from inside the box, thereby extending the service life of the box and improving the waterproof effect. However, external moisture can easily enter the box through gaps, resulting in poor waterproof effect, and it is not easy to support and wire the equipment required by the actuator, making installation inconvenient. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waterproof and dustproof electric actuator housing, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a waterproof and dustproof electric actuator housing, including a protective housing, on which protective components are provided;

[0007] The protective assembly includes a support liner frame disposed inside the protective housing. The support liner frame is detachably connected to the protective housing by bolts. Two limiting plates are installed on the surface of the support liner frame by bolts. Several wire harnesses are embedded in the support liner frame.

[0008] Two limiting slots are provided on one side of the surface of the protective box. An elastic sealing frame is engaged in each of the two limiting slots, and a sponge filter plate is provided on each of the elastic sealing frames. A protective cabinet door is provided on one side of the surface of each of the two limiting slots, and several air guides are provided on each of the protective cabinet doors. Two second connecting blocks are fixedly provided on one side of the protective cabinet door, and a first connecting block is rotatably connected to the bottom of each second connecting block. The first connecting block is installed on the protective box.

[0009] As can be seen, in the above technical solution, the equipment required by the actuator is positioned by using the supporting inner liner and the limiting plate as the supporting surface. At the same time, the wiring harness on the supporting inner liner facilitates the wiring of electrical equipment and avoids messy wires. When the protective cabinet door is closed, one side of the protective cabinet door can be inserted into the limiting slot and squeeze the elastic sealing frame. The elastic sealing frame deforms under force to fill the gap between the protective cabinet door and the protective box, preventing external water stains from seeping into the protective box and improving its waterproof performance. It can also filter the airflow through the sponge filter plate to improve the dustproof performance.

[0010] Optionally, in one possible implementation, the top and bottom of the protective enclosure are provided with side baffles, which are detachably connected to the protective enclosure by bolts. Each of the two side baffles has two staggered openings, and each staggered opening has a pull rod inserted into it. The supporting inner liner is a rectangular frame structure, and the supporting inner liner has several frame openings. The supporting inner liner is provided with two limit locks, and each limit lock passes through the corresponding protective cabinet door and extends to the outside of the protective cabinet door.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By setting up protective components, the overall design is simple and the structure is reasonable compared with the existing technology. Through the corresponding cooperation of various structures, the supporting inner liner and the limiting plate serve as the support surface to position the equipment required by the actuator. At the same time, the wiring harness on the supporting inner liner facilitates the wiring of electrical equipment and avoids messy wires.

[0013] Furthermore, the protective cabinet door can deflect on the protective box body via the first and second connecting blocks, facilitating the opening and closing of the protective cabinet door. When the protective cabinet door is closed, one side of the protective cabinet door can be inserted into the limiting slot and squeeze the elastic sealing frame. The elastic sealing frame deforms under force to fill the gap between the protective cabinet door and the protective box body, preventing external water stains from seeping into the protective box body and improving its waterproof performance. It can also filter the airflow through the sponge filter plate, improving its dustproof performance. Attached Figure Description

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.

[0021] As attached Figure 1-4 The waterproof and dustproof electric actuator housing shown here uses protective components on the protective housing 1 to position the equipment required by the actuator, with the supporting inner liner 2 and the limiting plate 3 as the support surface. At the same time, the wiring harness on the supporting inner liner 2 facilitates the wiring of electrical equipment and avoids messy wires. When the protective cabinet door 7 is closed, one side of the protective cabinet door 7 can be inserted into the limiting slot 4 and squeeze the elastic sealing frame 5. The elastic sealing frame 5 deforms under force to fill the gap between the protective cabinet door 7 and the protective housing 1, preventing external water stains from seeping into the protective housing 1 and improving its waterproof performance. It can also filter the airflow through the sponge filter plate 6 to improve the dustproof performance. The specific structural settings of the components are as follows.

[0022] The protective assembly includes a support inner liner 2 installed inside the protective housing 1. The support inner liner 2 is detachably connected to the protective housing 1 by bolts. Two limit plates 3 are installed on the surface of the support inner liner 2 by bolts. Several wire harnesses are embedded in the support inner liner 2.
