Description

Technical Field

[0001] The utility model relates to the technical field of switch machines, in particular to a shaft blocking plate structure for a waterproof electric switch machine. Background Art

[0002] In the existing electric switch machine, only a rubber pad is relied on for sealing at the shaft blocking plate part, and the overall protection level is IP54, which cannot ensure use in a submerged environment. For a waterproof switch machine with a high protection level, the original shaft blocking plate structure is no longer applicable. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the technology and provide a shaft blocking plate structure for a waterproof electric switch machine. While ensuring the installation and positioning of the main shaft by the inner shaft blocking plate, sealing is achieved by the outer shaft blocking plate, the sealing ring and the bottom shell.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A shaft blocking plate structure for a waterproof electric switch machine includes a bottom shell, a main shaft, an inner shaft blocking plate, an outer shaft blocking plate and a sealing ring. The main shaft penetrates from the outside of the bottom shell into the inside. The inner shaft blocking plate is fixed on the bottom shell to position the main shaft. The sealing ring is installed in the groove of the bottom shell, and the outer shaft blocking plate is fixedly installed on the bottom shell by screws to fix the sealing ring.

[0006] Preferably, the inner shaft blocking plate is fixed on the bottom shell by bolts and spring washers.

[0007] Preferably, the outer shaft blocking plate is of a diamond structure, and a groove for placing the outer shaft blocking plate is provided on the bottom shell, and the depth of the groove is the same as the thickness of the outer shaft blocking plate.

[0008] The beneficial effect of the utility model is that by using the utility model, it can ensure the installation and positioning of the main shaft by the inner shaft blocking plate, and sealing is achieved by the outer shaft blocking plate, the sealing ring and the bottom shell, solving the defect of poor sealing at the installation part of the main shaft of the bottom shell of the original electric switch machine and improving the protection level of the switch machine.

[0013] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0014] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the 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. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0015] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "install", "connect", "connection", "fixed connection", "fixed joint" 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 or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0016] The following will describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and preferred embodiments. As Figure 1 、 Figure 2 and Figure 3As shown in the figure, a shaft blocking plate structure for a waterproof electric switch machine includes a bottom shell 1, a main shaft 2, an inner shaft blocking plate 3, an outer shaft blocking plate 4, and a sealing ring 7. The main shaft 2 penetrates from the outside of the bottom shell 1 into the inside. The inner shaft blocking plate 3 is fixed to the bottom shell 1 using bolts 5 and spring washers 6 and limits the main shaft 2. Specifically, the inner shaft blocking plate 3 is circular and is fixed to the bottom shell by two bolts. The end of the main shaft is blocked and limited by the inner shaft blocking plate. A groove 101 is provided on the bottom shell 1, and the sealing ring 7 is installed in the groove 101 of the bottom shell 1. The outer shaft blocking plate 4 is fixedly installed on the bottom shell 1 by screws 8 to fix the sealing ring 7. The outer shaft blocking plate is a rhombus structure, specifically, a hexagon. A groove for placing the outer shaft blocking plate is provided on the bottom shell. The depth of the groove is the same as the thickness of the outer shaft blocking plate, and the outer shaft blocking plate can be completely buckled in the groove to form an integral body with the bottom shell.

[0017] By using the present utility model, it can ensure that the inner shaft blocking plate 3 installs and positions the end of the main shaft 2, and the outer shaft blocking plate 4, the sealing ring 7 and the bottom shell 1 achieve sealing, solving the defect of poor sealing at the installation part of the main shaft of the original electric switch machine bottom shell, and improving the protection level of the switch machine.

[0018] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
