Description

Technical Field

[0001] The utility model relates to the technical field of oil injection devices, in particular to a split actuating rod for a waterproof electric switch machine. Background Art

[0002] Currently, most of the waterproof electric switch machines use the old-fashioned actuating rods. Since the connection part with the switch rail is larger than the diameter of the whole rod, it needs to be inserted into the circular hole sleeve of the switch machine from the thin end when penetrating. Because there are many slot holes processed in the middle of the actuating rod, the edge of the hole is easy to scratch the sealing ring when penetrating the circular hole sleeve, resulting in a decline in the sealing performance of this part. Moreover, when replacing the sealing ring of the circular hole sleeve in the later stage, the whole actuating rod needs to be removed, which is inconvenient for on-site signal maintenance personnel to operate. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in technology and provide a split actuating rod for a waterproof electric switch machine. Since its connection head can be disassembled, the installation of the circular hole sleeve and the replacement of the sealing ring in the later stage can both be inserted from one side of the threaded part of the rod. This avoids scratching the sealing ring and is convenient for operation.

[0004] In order to achieve the above object, the utility model adopts the following technical solutions:

[0005] A split actuating rod for a waterproof electric switch machine, characterized in that: it includes a rod, a lock nut, a connection head, a set screw and a double-stack self-locking washer. The lock nut is screwed into the threaded part of the rod, the double-stack self-locking washer is sleeved on the threaded part of the rod, the connection head is screwed into the threaded part of the rod, a threaded hole is provided on the connection head, a V-shaped groove is provided on the threaded part of the rod, and the set screw is screwed into the threaded hole until it compresses the V-shaped groove, and the lock nut is tightened to compress the double-stack self-locking washer and the connection head.

[0006] Preferably, the V-shaped groove is located at the axial position of the rod.

[0007] Preferably, a connection hole is provided on the connection head.

[0008] The beneficial effect of the utility model is that: in the utility model, the connection head can be disassembled, and the installation of the circular hole sleeve and the replacement of the sealing ring in the later stage can both be inserted from one side of the threaded part of the rod. This avoids scratching the sealing ring and is convenient for operation. Description of the Drawings

[0011] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0012] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "up", "down", "front", "back", "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 indicating 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 "a plurality" is two or more.

[0013] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection", "fixed connection", "fixed joint" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can 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 circumstances.

[0014] 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 shown, a split actuating rod for a waterproof electric switch machine includes a rod 1, a lock nut 2, a connector 3, a set screw 4, and a double-stack self-locking washer 5. The lock nut 2 is screwed into the threaded part of the rod 1, the double-stack self-locking washer 5 is sleeved on the threaded part of the rod 1, the connector 3 is screwed into the threaded part of the rod 1, and the set screw 4 is screwed into the threaded hole 301 of the connector 3 until it compresses the V-shaped groove 101 of the rod 1, and the lock nut 2 is tightened to compress the double-stack self-locking washer 5 and the connector 3. The installation sequence is to first screw the lock nut 2 onto the rod 1, then sleeve the double-stack self-locking washer 5, then screw in the connector 3, and finally tighten the set screw.

[0015] In the present utility model, the installation positioning can be achieved through the set screw 4 and the V-shaped groove 101 of the rod 1, and the overall fixation is achieved after the lock nut 2 is tightened to compress the double-stack self-locking washer 5 and the connector 3.

[0016] Since the whole structure is a detachable structure, it can be inserted through the threaded part of the rod 1 when installing the round hole sleeve and replacing the sealing ring later, which avoids scratching the sealing ring and is convenient for operation.

[0017] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
