Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, and particularly belongs to a speed reduction motor junction box. Background Art

[0002] The existing speed reduction motor junction box is mainly composed of an upper cover and a lower cover. The wiring components are mainly arranged in the lower cover. However, the depth of the current lower cover of the junction box is relatively large, making the installation and maintenance of the wiring components inconvenient. Moreover, the perimeters of the four sides of the current upper cover and lower cover are inconsistent. When assembling and installing, it is also necessary to fit and install at a specific angle, and the angle needs to be adjusted in advance during installation, which is time-consuming. Content of the Utility Model

[0003] The purpose of the utility model is to provide a speed reduction motor junction box, which overcomes the deficiencies of the prior art.

[0004] To solve the above problems, the technical solutions adopted by the utility model are as follows:

[0005] A speed reduction motor junction box includes an upper box body, a lower box body and a sealing gasket. The upper box body and the lower box body are cooperatively arranged to form a square box body. An installation hole is provided at the bottom of the lower box body. An installation groove is provided on the opening edge of the upper box body. The sealing gasket is arranged in the installation groove so that when the upper box body and the lower box body are connected, the sealing gasket can seal the connection between the upper box body and the lower box body. A wiring hole is also provided on one side surface of the upper box body.

[0006] Further, a screw hole is respectively provided at the four corners of the lower box body. Through holes corresponding to the screw holes are provided on the upper box body. The connection part between the upper box body and the lower box body is a square frame structure. The screw holes and the through holes are located at the four corners of the square frame structure.

[0007] Further, the depth of the upper box body is greater than the depth of the lower box body.

[0008] Further, wiring holes are also provided on the lower box body around the installation hole.

[0009] Further, a boss is provided on the outer surface of the lower box body around the installation hole. A positioning groove and a connection hole are also provided on the surface of the boss.

[0010] Compared with the prior art, the implementation effects of the utility model are as follows:

[0011] By reducing the depth of the lower box body and increasing the depth of the upper box body, the wiring components are made more convenient to install and maintain in the lower box body. Moreover, an installation groove is provided on the upper box body, facilitating the installation of the gasket, so that when the upper box body is installed on the lower box body, the gasket is not easily dropped. At the same time, through the cooperation of the gasket and the installation groove, the sealing performance between the upper box body and the lower box body is improved, enhancing the waterproof and dustproof performance of the junction box. The connection part between the upper box body and the lower box body is a square frame structure, and the screw holes and through holes are located at the four corners of the square frame structure, enabling the upper box body to be installed in any direction as long as the screw holes and through holes can correspond, making the installation more convenient.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As Figures 1-4 shown, the speed reduction motor junction box includes an upper box body 3, a lower box body 1, and a gasket 2. The upper box body 3 and the lower box body 1 are cooperatively arranged to form a square junction box body. The depth of the upper box body 3 is greater than that of the lower box body 1, and the depth of the lower box body 1 does not exceed 20 mm, making it more convenient to install and repair the wiring components in the lower box body 1. In addition, the bottom of the lower box body 1 is further provided with mounting holes 12, and the outer surface around the mounting holes 12 is further provided with bosses 13. The surface of the bosses 13 is further provided with positioning grooves 14 and connection holes 15. The limiting grooves on the bosses 13 facilitate the positioning and installation of the lower box body 1, and the connection holes 15 facilitate the installation of the lower box body 1 during use.

[0021] The opening edge of the upper box body 3 is provided with a mounting groove 31, and the gasket 2 is installed in the mounting groove 31. When the upper box body 3 and the lower box body 1 are connected, the gasket 2 can seal the connection between the upper box body 3 and the lower box body 1. The mounting groove 31 makes it difficult for the gasket 2 to fall off when the upper box body 3 is installed on the lower box body 1. One side of the upper box body 3 is further provided with a wiring hole 4, which is convenient for connecting the power cord.

[0022] In addition, a screw hole 11 is respectively provided at the four corners of the lower box body 1, and a through hole 32 corresponding to the screw hole 11 is provided on the upper box body 3. The connection between the upper box body 3 and the lower box body 1 is a square frame structure, and the screw holes 11 and the through holes 32 are located at the four corners of the square frame structure. In any direction of the upper box body 3, as long as the screw holes 11 and the through holes 32 can correspond, the upper box body 3 can be installed, making the installation more convenient.
