[0039] The embodiment of the present application discloses a phase sequence plate installation device.

[0040] See also Figure 1 as well as Figure 2 , an embodiment of a phase sequence card installation device provided in the embodiments of the present application includes:

[0041] The device body 1 and the installation component, the device body 1 is provided with a hollow cavity 2, and the bottom is provided with an installation port 3 connected to the hollow cavity, the installation component includes: a mounting block 5, a slider 7, a pin rod 12, a first elastic component with a preset compression amount and a locking block 21, the slider 7 is slidably matched with the through cavity 6, and the pin rod 12 is movably inserted on the first end, and a first oblique wedge surface 211 is provided on the second end, the mounting block 5 is fixed on the phase sequence plate 4 and is provided with a through cavity 6, the locking block 21 is fixed in the hollow cavity 2, and has a second oblique wedge surface 71 matched with the first oblique wedge surface 211, the first end of the first elastic component is connected to the mounting block, and the second end is connected to the slider 7, so that the slider 7 slides toward the locking block 21, the pin rod 12 is movably locked with the inner concave hole 13 on the phase sequence plate 4, and the horizontal matching stroke between the first oblique wedge surface 211 and the second oblique wedge surface 71 is greater than the distance between the pin rod 12 and the inner concave hole 13.

[0042] Specifically, when the slider 7 is inserted between the locking block 21 and the bottom wall of the hollow cavity 2, Figure 1The horizontal stroke of the sliding cooperation between the first inclined wedge surface 211 and the second inclined wedge surface 71 is greater than the distance limit between the pin rod 12 and the inner recessed hole 13, so that it can be ensured that the cooperation stroke between the first inclined wedge surface 211 and the second inclined wedge surface 71 is sufficient to move the slider 7 to the cooperation between the pin rod 12 and the inner recessed hole 13 during disassembly, so that the slider 7 will not rebound before the stroke is completed, resulting in the inability to smoothly remove the phase sequence plate 4.

[0043] The installation and disassembly principle of the phase sequence plate 4 is as follows: during installation, the phase sequence plate 4 is lifted and dragged toward the installation opening 3 until the bottom surface of the slider 7 is flush with the bottom surface of the hollow cavity 2, so that when the pin rod 12 is pulled up, the slider 7 can extend into the hollow cavity 2 in the direction of the locking block 21 through the preload force provided by the first spring 10, and be embedded between the locking block 21 and the bottom surface of the hollow cavity 2, and the locking block 21 is used to fix the slider 7, thereby fixing the phase sequence plate 4, wherein the pin rod 12 can be pulled up manually by opening an operation port (not shown) on one side of the device body 1, of course, it is not limited to this operation method, and the inner concave hole 12 can also be pulled up. One side of the phase sequence plate 4 passes through the side wall of the phase sequence plate 4, and then an inclined wedge block is inserted in the inner concave hole 13, the inclined wedge block is pushed, and the inclined wedge surface of the inclined wedge block is used to lift the pin rod 12, so that the pin rod 12 is pushed out of the inner concave hole 13, and there is no specific restriction; when disassembling, the phase sequence plate 4 is lifted vertically upward into the installation opening 3 to realize the sliding between the slider 7 and the locking block 21, and the vertical movement to horizontal movement principle in the inclined wedge cooperation is used to promote the slider 7 to move in the direction away from the locking block 21. When the slider 7 is fixed by the pin rod 12 and the inner concave hole 13, the slider 7 is reset and locked at this time, so that the phase sequence plate 4 can be easily removed.

[0044] It can be seen from the above technical scheme that the present application cleverly utilizes the cooperation between the first oblique wedging surface 211 of the locking block 21 and the second oblique wedging surface 71 of the slider 7 to realize the conversion from vertical movement to horizontal movement. In this way, when disassembling, it is only necessary to lift the phase sequence plate 4 upward in the vertical direction to realize the sliding between the slider 7 and the locking block 21, thereby enabling the slider 7 to move in the direction away from the locking block 21. When the slider 7 is fixed by the cooperation of the pin rod 12 and the inner concave hole 13, the phase sequence plate 4 can be taken out, and the disassembly is quick and convenient. During the installation process, when aligning the positions of the slider 7 and the locking block 21, the pin rod 12 can be pushed up, so that the slider 7 can use the preload force generated by the first elastic component to extend into the hollow cavity 2 and get stuck between the locking block 21 and the bottom wall of the hollow cavity 2, so as to achieve fixation. The installation is quick and convenient, which is convenient for the operator to perform maintenance operations.

[0045] The above is the first embodiment of a phase sequence card installation device provided by the embodiment of the present application. The following is the second embodiment of a phase sequence card installation device provided by the embodiment of the present application. For details, please refer to Figures 1 to 3 .

[0046] A phase sequence plate installation device comprises: a device body 1 and an installation component, wherein a hollow cavity 2 is provided in the device body 1, and an installation opening 3 communicating with the hollow cavity is provided at the bottom, the installation component comprises: a mounting block 5, a slider 7, a pin rod 12, a first elastic component with a preset compression amount and a locking block 21, the mounting block 5 is fixed on the phase sequence plate 4 and is provided with a through cavity 6, the slider 7 is slidably matched with the through cavity 6, and the pin rod 12 is movably inserted on the first end portion, and a first oblique wedging surface 211 is provided on the second end portion, the locking block 21 is fixed in the hollow cavity 2, and has a second oblique wedging surface 71 matched with the first oblique wedging surface 211, the first end of the first elastic component is connected to the mounting block, and the second end is connected to the slider 7, so that the slider 7 slides toward the locking block 21, the pin rod 12 is movably locked with the inner concave hole 13 on the phase sequence plate 4, and the horizontal matching stroke between the first oblique wedging surface 211 and the second oblique wedging surface 71 is greater than the distance between the pin rod 12 and the inner concave hole 13.

[0047] Furthermore, the slider 7 is provided with an inner groove 9 for accommodating the first elastic component; one end wall side of the inner groove 9 is provided with a stop block 8 fixedly connected to the mounting block 5 and in contact with and abutting against the first end of the first elastic component, and the other end wall is in contact with and abutting against the second end of the first elastic component.

[0048] Specifically, the inner groove 9 may be provided with one, and one inner groove 9 may be provided on the top and bottom surfaces or both sides of the slider 7. In the case of multiple inner grooves 9, there may be multiple first elastic components, which can further ensure that the force of the slider 7 is balanced and the sliding stability of the slider 7 is ensured.

[0049] Furthermore, the first elastic component is an elastic sheet (not shown) or a first spring 10 .

[0050] Specifically, when the first elastic component is an elastic sheet or a first spring 10 , it can be directly disposed in the inner groove 9 , with one end contacting and abutting against the stop block 8 , and the other end contacting and abutting against the slider 7 .

[0051] Furthermore, of course, with respect to the first spring 10 as the first elastic component, it may also include, for example, a guide rod, the first spring 10 is sleeved on the guide rod 22 , one end of which is fixedly connected to the stop block 8 , and the other end of which is slidably matched with the slider 7 .

[0052] Specifically, by adding a guide rod 22 , the deformation path of the first spring 10 can be better stabilized, and the elastic force exerted on the slider 7 can be stabilized.

[0053] Furthermore, a fixing mechanism for fixing the locking block 21 is also included.

[0054] Specifically, the fixing mechanism can be a simple fastener such as a bolt, and the fastener is fixed to the side wall of the hollow cavity 2 and the locking block is fixed.

[0055] Furthermore, the fixing mechanism may also include, for example, a fixing rod 17, a fixing block 18, a connecting block 20 and a second spring 16. The fixing rod 17 is fixed in the hollow cavity 2. The connecting block 20 is movably mounted on the fixing rod 17 and fixedly connected to the locking block 21. The fixing block 18 is fixedly mounted on the fixing rod 17 and is located above the connecting block 20. The second spring 16 is mounted on the fixing rod 17, and one end is in contact with and abuts against the fixing block 18, and the other end is in contact with and abuts against the connecting block 20.

[0056] Specifically, the second spring 16 also applies a pre-tightening force to the lock block 21, so that when the slider 7 is inserted into the lock block 21 and the bottom wall of the hollow cavity 2, the lock block 21 also exerts a squeezing force on the slider 7, so that the slider 7 is better fixed and the phase sequence plate 4 is ensured to be firmly installed.

[0057] Of course, the locking block 21 can also be directly fixed on the side wall of the accommodating cavity 2, or fixed in other fixing ways. Those skilled in the art can make appropriate changes based on this, and there is no specific limitation.

[0058] In addition, the connecting block 20 and the locking block 21 can be an integral structure, and the locking block 21 can be correspondingly set to a trapezoidal block, so that the required first bevel surface 211 can be naturally formed. Of course, it is not limited to the trapezoidal block, and it can also be any block that can form the first bevel surface 211. Technical personnel in this field can make appropriate changes based on this, and there is no specific limitation.

[0059] Furthermore, it also includes a plurality of second elastic components with preset compression amounts, so that the pin rod 12 moves toward the inner concave hole 13.

[0060] Specifically, by providing a pre-tightening force to the pin rod 12, it can help the pin rod 12 to better fit into the inner recessed hole 13, ensure that the pin rod 12 locks the slider 7 in time, avoid the pin rod 12 from accidentally falling out, and improve the stability of the slider 7 reset and lock.

[0061] Furthermore, the second elastic component is an elastic rope (not shown) or a third spring 19 .

[0062] Specifically, when the second elastic component is an elastic rope, one end of the elastic rope is fixedly connected to the top of the pin rod 12 , and the other end is fixedly connected to the top surface of the slider 7 .

[0063] Furthermore, of course, when the second elastic component is the third spring 19, its specific implementation means may also include, for example, a limit block corresponding to the third spring 19, the limit block 15 is slidably arranged in the avoidance cavity 14 in the slider 7, and the third spring 19 is arranged between the limit block and the top wall of the avoidance cavity 14.

[0064] Specifically, a pin hole 11 for the pin rod 12 to pass through is provided at a position corresponding to the installation position of the pin rod 12 on the slider 7, and an avoidance cavity 14 is expanded in the middle position of the pin hole 11 to provide a sliding space for the limit block 15, and then the third spring 19 is used to provide a preload force.

[0065] Of course, the present embodiment is not limited to the above-mentioned elastic rope or the third spring 19. Those skilled in the art can make appropriate changes based on this, and there is no specific limitation.

[0066] Furthermore, there are two groups of installation components in total and they are symmetrically arranged.

[0067] Specifically, two groups of installation components are designed and are symmetrical to each other, which can further improve the installation firmness of the phase sequence plate 4.

[0068] It can be seen from the above technical scheme that the present application cleverly utilizes the cooperation between the first oblique wedging surface 211 of the locking block 21 and the second oblique wedging surface 71 of the slider 7 to realize the conversion from vertical movement to horizontal movement. In this way, when disassembling, it is only necessary to lift the phase sequence plate 4 upward in the vertical direction to realize the sliding between the slider 7 and the locking block 21, thereby enabling the slider 7 to move in the direction away from the locking block 21. When the slider 7 is fixed by the cooperation of the pin rod 12 and the inner concave hole 13, the phase sequence plate 4 can be taken out, and the disassembly is quick and convenient. During the installation process, when aligning the positions of the slider 7 and the locking block 21, the pin rod 12 can be pushed up, so that the slider 7 can use the preload force generated by the first elastic component to extend into the hollow cavity 2 and get stuck between the locking block 21 and the bottom wall of the hollow cavity 2, so as to achieve fixation. The installation is quick and convenient, which is convenient for the operator to perform maintenance operations.

[0069] The above is a detailed introduction to a phase sequence plate installation device provided by the present application. For a person skilled in the art, according to the idea of ​​the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
