[0023] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] In the description of the present invention, terms such as "up", "down", "left", "right", "front", "back", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, 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 of the present invention.

[0025] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 4 As shown, the embodiment provides an integrated locking assembly fixture for an isolating switch, comprising a mounting frame 10, a lifting drive 30 and a carrier plate 20; the mounting frame 10 has an upper mounting plate 11 and a receiving space 101 located below the upper mounting plate 11, a vertically penetrating window 111 is provided in the middle of the upper mounting plate 11, the lifting drive 30 is installed in the receiving space 101 of the mounting frame 10, the lifting shaft of the lifting drive 30 is passed through the window 111 and is equipped with an ejection plate 31; in this way, the lifting drive 30 can drive the ejection plate 31 to move up and down. The carrier plate 20 is mounted on the upper mounting plate 11, and a support column 21 is fixed on the carrier plate 20; a nut limiting groove 211 is provided at the top of the support column 21, and the nut limiting groove 211 is used to place the nut 1 and limit its circumferential rotation.

[0027] The jig used in this embodiment, when assembling, first place the nut 1 in the nut limiting groove 211 of the support column 21. The nut limiting groove 211 can limit the circumferential rotation of the nut. In this embodiment, the nut 1 is a hexagonal nut, and the groove wall of the nut limiting groove 211 of the support column 21 is compatible with the shape of the nut 1. Then position the lower shell 2 on the support column 21. Specifically, the setting of the support column 21 can be positioned and matched with the lower shell 2 to achieve precise assembly. After that, other components (such as contact structure, operating mechanism and upper shell 3, etc.) are spliced ​​in sequence. After the assembly is completed, Figure 5 As shown, finally, the screw is passed through the upper shell 3 and the lower shell 2 from top to bottom and locked on the nut 1. Since the nut 1 is restricted in the nut limiting groove 211 of the support column 21, invalid locking will not occur when locking the screw. In this way, the screw locking is more secure. After the assembly is completed, the lifting drive 30 drives the ejection plate to move upward to eject the assembled product 100 upward. The use of the jig of the present application can effectively improve the assembly efficiency and yield of the disconnector products.

[0028] Specifically, in this embodiment, there are two carriers 20, which are respectively mounted on opposite sides of the clearance window 111; two support columns 21 are fixed on each carrier 20, and the four support columns 21 on the two carriers 20 together constitute a support structure; forming a suspended support structure capable of supporting the four ends. Of course, in other embodiments, the number of support columns on each carrier can also be one or more than two, such as Figure 6 As shown, there are three support columns 21 on each carrier 20. The number of carriers 20 is not limited to two, and one or more than two may be used. When a whole carrier 20 is used, an opening corresponding to the clearance window 111 needs to be opened for the ejection plate 31 to pass through.

[0029] Furthermore, in order to make the fixture suitable for assembling products of different sizes and types, in this embodiment, the carrier plate 20 is detachably mounted on the upper mounting plate 11, and its detachable fixing method is achieved by bolt locking. If replacement is required, the bolts are first unscrewed, and a different carrier plate 20 can be replaced to adapt to the assembly of products of different sizes and types, and then the carrier plate 20 is locked by bolts after replacement. Of course, in other embodiments, the fixing method of the carrier plate 20 detachably mounted on the upper mounting plate 11 is not limited to this, and detachable fixing can also be achieved by a clamping method.

[0030] Furthermore, the upper mounting plate 11 and the carrier plate 20 are positioned and assembled by a positioning structure to ensure the subsequent assembly accuracy. Specifically, the positioning and assembly method is as follows: the upper mounting plate 11 is provided with a positioning column 112, and the carrier plate 20 is provided with a positioning hole 22. The positioning hole 22 of the carrier plate 20 is sleeved on the positioning column 112 and positioned and assembled on the upper mounting plate 11. The matching method of the positioning column 112 and the positioning hole 22 is adopted, and the structure is simple; of course, in other embodiments, the positioning and assembly structure is not limited to this, and other structures can also be adopted to achieve it, such as a limiting block limited around the carrier plate.

[0031] Furthermore, the support column 21 is also provided with a clearance hole 212, and the clearance hole 212 is connected to the bottom of the nut limiting groove 211; the setting of the clearance hole 212 allows the locking screw to have downward extension space, that is, when locking the screw, the screw can continue to extend downward into the clearance hole 212 after passing through the nut 1, thereby ensuring the stable locking of the screw.

[0032] The ejection plate 31 is made of a material with certain elasticity, such as a rubber plate in this embodiment, which has a certain cushioning effect after ejection and is not easy to damage the product.

[0033] The installation frame 10 further includes a lower bottom plate 12, a left side plate 13 and a right side plate 14. The upper installation plate 11 and the lower bottom plate 12 are arranged at intervals from top to bottom. The left side plate 13 and the right side plate 14 are respectively connected to the left and right sides of the upper installation plate 11 and the lower bottom plate 12 to form a "mouth"-shaped installation frame 10; the space enclosed by the upper installation plate 11, the lower bottom plate 12, the left side plate 13 and the right side plate 14 is the accommodating space 101; the lifting drive 30 is fixed on the lower bottom plate 12. Such an arrangement makes the structure of the installation frame 10 simple and easy to implement. Of course, in other embodiments, the composition structure of the installation frame 10 is not limited to this, such as it can also be a six-sided closed box body (only a clearance window is opened on the upper installation plate), etc.

[0034] Specifically, in this embodiment, the lifting actuator 30 is a lifting cylinder, which is used to drive the ejection plate 31 to move, and has a simple structure and is easy to implement. Of course, in other embodiments, the lifting actuator 30 can also use other devices such as electric push rods that can drive the ejection plate 31 to move.

[0035] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
