Description

Technical Field

[0001] The utility model relates to the technical field of oil injection devices, in particular to an indicator rod cover cylinder for a waterproof switch machine. Background Art

[0002] To ensure a good seal, current waterproof switch machine cover tubes are often screwed directly to the base casing. When railway electrical personnel need to adjust the switch gap, removing the screws is cumbersome and carries the risk of losing or damaging the seal. Conventional switch machine cover tubes, while easy to disassemble, lack a good seal and are unable to prevent water from entering the machine when submerged. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned technology and provide a waterproof switch machine indicating rod cover cylinder, which is convenient for railway electricians to adjust the switch machine indicating rod gap and ensures the overall waterproof performance of the switch machine.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] A waterproof switch machine indicator rod cover is characterized by comprising a bottom shell, an indicator cover sleeve, an indicator adjustment sleeve and an indicator adjustment cover, wherein the indicator cover sleeve and the indicator adjustment sleeve are fixed to the bottom shell by screws, the indicator adjustment sleeve is fixed to the indicator cover sleeve, and the indicator adjustment cover is connected to the indicator adjustment sleeve using threads.

[0006] Preferably, an upper indicating cover sleeve groove and a lower indicating cover sleeve groove are respectively provided on both sides of the indicating cover sleeve, and a first O-ring and a second O-ring are respectively installed in the upper indicating cover sleeve groove and the lower indicating cover sleeve groove.

[0007] Preferably, the adjustment tube is provided with an adjustment tube groove, a combination gasket is installed in the adjustment tube groove, and the front end of the adjustment cover is provided with an adjustment cover end surface sink, which cooperates with the combination gasket.

[0008] The beneficial effect of the present invention is that railway electrical personnel can adjust the gap of the switch machine by rotating the indicator adjustment cover. After adjustment, the indicator adjustment cover and the indicator adjustment cylinder are tightened until the combined pad is pressed. This facilitates assembly and disassembly while ensuring the protection level of the entire machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0013] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are 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 cannot be understood as a limitation on the present invention. In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined as "first", "second" and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0014] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixedly connected," and "fixed connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art can understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0015] The following describes the specific implementation of the present invention in detail with reference to the accompanying drawings and preferred embodiments. Figure 1 、 Figure 2As shown, a waterproof switch machine indicating rod cover includes a bottom shell 1, an indicating cover sleeve 2, an indicating adjustment sleeve 3, an indicating adjustment cover 4, a first O-ring 501, a second O-ring 502 and a combination gasket 6. The indicating cover sleeve 1 and the indicating adjustment sleeve 2 are fixed to the bottom shell by screws 7. The first O-ring 501 and the first O-ring 502 are installed in the upper indicating cover sleeve groove 201 and the lower indicating cover sleeve groove 202. The first O-ring 501 and the second O-ring 502 are rectangular sealing rings. In order to compress the sealing ring, the combination gasket 6 is installed in the indicating adjustment sleeve groove 301. The indicating adjustment cover 4 is connected to the indicating adjustment sleeve 3 using threads. When tightened, the end face sink 401 of the indicating adjustment cover can compress the combination gasket 6.

[0016] In the utility model, the railway electrician can dismantle the display adjustment cover 4 by rotating it, thereby adjusting the gap of the switch machine. After the adjustment is completed, tighten the display adjustment cover 4 and the display adjustment cylinder 3 until the combined pad 6 is compressed.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
