Description

Technical Field

[0001] This utility model relates to the field of electric actuator door technology, and in particular to a water-proof device for the door shaft of an electric actuator. Background Technology

[0002] During use, water can easily enter the door hinge area of ​​an electric actuator due to poor sealing. The internal components of the electric actuator, such as the motor, are sensitive to water and are prone to malfunction or even burnout after water enters, affecting the normal operation of the equipment.

[0003] Traditional door hinge sealing methods often use simple sealing rings, which are prone to wear after long-term use, resulting in a decrease in sealing effect and difficulty in effectively preventing water intrusion.

[0004] Currently, there are some improvements to the door hinge seal, such as increasing the number of sealing layers, but these do not form a matching structure between the stationary and rotating rings. As a result, the sealing performance is unstable during the rotation of the door hinge, and there is still a risk of water ingress. Utility Model Content

[0005] The purpose of this utility model is to provide a water-proof device for the door shaft of an electric actuator. By adding a sealing baffle plate to the side of the door shaft of the electric actuator and adding a sealing strip on the shaft to seal it as the shaft rotates, it can effectively prevent water from entering the electric actuator along the shaft and burning it out.

[0006] This utility model provides a water-proof device for the door hinge of an electric actuator, including a first sealing mechanism installed on the side of the door hinge of the electric actuator, the first sealing mechanism being tightly connected to the peripheral components of the door hinge; and a second sealing mechanism installed on the door hinge of the electric actuator, corresponding to the position of the first sealing mechanism, the second sealing mechanism being tightly fitted to the door hinge of the electric actuator and rotating synchronously with the door hinge of the electric actuator.

[0007] Furthermore, the first sealing mechanism employs a water-retaining ring.

[0008] Furthermore, the water-retaining ring is made of metal.

[0009] Furthermore, the water-retaining ring is made of aluminum alloy.

[0010] Furthermore, the thickness of the water-blocking ring is 10mm-35mm, and the diameter is 50-70mm.

[0011] Furthermore, the second sealing mechanism employs a sealing strip.

[0012] Furthermore, a fitting gap is left between the water-blocking ring and the sealing strip.

[0013] Furthermore, the fitting clearance is 3mm-10mm.

[0014] Furthermore, the sealing strip is made of rubber.

[0015] Furthermore, the sealing strip has a threaded structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The sealing structure, which combines the first and second sealing mechanisms, provides more stable sealing performance and effectively prevents water intrusion. 2. The sealing components wear slowly, have a long service life, and reduce maintenance frequency; 3. It does not affect the normal rotation function of the door hinge, ensuring the normal use of the electric actuator door. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a water-proof device for the door shaft of an electric actuator, including a first sealing mechanism 4 installed on the side of the door shaft 6 of the electric actuator, the first sealing mechanism being tightly connected to the peripheral components of the door shaft 6 of the electric actuator; and a second sealing mechanism 3 installed on the door shaft 6 of the electric actuator, corresponding to the position of the first sealing mechanism, the second sealing mechanism 3 being tightly fitted to the door shaft 6 of the electric actuator and rotating synchronously with the door shaft 6 of the electric actuator.

[0024] The first sealing mechanism 4 forms a fixed first sealing barrier; the second sealing mechanism 3 rotates synchronously with the electric actuator door shaft 6 to form a second sealing barrier.

[0025] The first sealing mechanism 4 employs a water-retaining ring, which is made of metal, preferably aluminum alloy. The thickness of the water-retaining ring is 10mm-35mm, and the diameter is 50-70mm.

[0026] The second sealing mechanism 3 uses a sealing strip. A fitting gap is left between the water-blocking ring and the sealing strip, preferably 3mm-10mm. Maintaining a reasonable gap between the water-blocking plate and the sealing strip ensures that the door hinge rotation is not affected, while simultaneously forming an effective seal to prevent water from entering through the door hinge gap.

[0027] The sealing strip is made of rubber. The sealing strip has a threaded structure.

[0028] This utility model adds water baffles on both sides of the door shaft 6 of the electric actuator. The baffles are made of aluminum alloy and have the advantages of being waterproof and corrosion resistant. The aluminum alloy baffles are double water baffles. The door shaft 6 of the electric actuator is also equipped with double sealing strips that rotate with the shaft and are made of rubber. These four measures prevent water from entering the electric actuator along the shaft and burning it out.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
