Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator electrical control component installation technology, specifically to a quick replacement device for elevator electrical control components. Background Technology
[0002] Early elevator electrical control components were relatively simple. However, with the increasing demands for intelligent and high-speed systems, today's components are more sophisticated and complex, possessing multiple functions such as efficient control, precise positioning, and safety protection. They play a crucial role in ensuring the safe, stable, and comfortable operation of elevators. Elevator electrical control components refer to various functional parts within the elevator's electrical control system. These include control boards, frequency converters, relays, buttons, and switches.
[0003] A Chinese patent (publication number CN220412520U) discloses an elevator mainboard mounting structure. This utility model uses an L-shaped fixing block movably set on the mounting plate to cooperate with the fixing plate, thereby fixing the elevator mainboard to the mounting plate. When the elevator mainboard malfunctions and needs to be repaired, the elevator mainboard can be disassembled without the use of special tools. The elevator mainboard is easy to disassemble and assemble during the repair process, which can effectively improve the repair efficiency of the elevator mainboard. By adjusting the position of the L-shaped fixing block, the mounting plate can fix elevator mainboards of different sizes.
[0004] However, in actual use, when fixing or replacing the elevator mainboard, the above-mentioned elevator mainboard installation structure requires turning the first rotating handle along the four sides of the mainboard in sequence to drive the first lead screw to rotate, thereby driving the L-shaped fixing block to move and fix the mainboard. The turning steps are numerous and the operation process is cumbersome, resulting in low operating efficiency for the staff. Utility Model Content
[0005] The purpose of this invention is to provide a quick replacement device for elevator electrical control components to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention provides a base plate, the base plate having a first mounting groove inside, a first bidirectional screw being rotatably mounted inside the first mounting groove, a first slider being threaded onto the outer side of the first bidirectional screw, the first slider being slidably disposed inside the first mounting groove, two first sliders being provided, the two first sliders being symmetrically arranged on both sides of the first mounting groove with the vertical axis of the first bidirectional screw as the center, a mounting seat being provided on the top of the first slider, a second mounting groove being provided above the first mounting groove, the second mounting groove being perpendicular to the first mounting groove, a second bidirectional screw being rotatably mounted inside the second mounting groove, a second slider being threaded onto the inner and outer sides of the second bidirectional screw, and four mounting seats being provided, one of which is located on the top of the second slider.
[0007] Furthermore, the mounting base is L-shaped, with a baffle slidably connected to one side of the mounting base, and a snap-fit block fixedly connected to the center of the baffle.

A compression spring is fixedly connected to one side of the baffle, and the other end of the compression spring is fixedly connected to the mounting base.
[0008] Furthermore, a first connecting plate is fixedly connected to the top of the first slider, and the top of the first connecting plate is fixedly connected to the mounting base. A first sliding groove is provided on the top of the base plate, and the first sliding groove communicates with the first mounting groove. The first connecting plate is slidably disposed inside the first sliding groove. A second connecting plate is fixedly connected to the top of the second slider, and a second sliding groove is provided on the top of the base plate. The second sliding groove is slidably connected to the second connecting plate.
[0009] Furthermore, an anti-slip pad is fixedly connected to the side of the baffle away from the snap-fit block, and the anti-slip pad is made of rubber.
[0010] Furthermore, a telescopic component is fixedly installed on one side of the baffle, and the telescopic end of the telescopic component is fixedly connected to the mounting base.
[0011] Furthermore, a threaded hole is provided on the top of the base plate, and a bolt is threaded into the threaded hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: after the base plate is fixed inside the elevator, the motherboard and other accessories can be easily replaced and installed on the base plate. When replacing, the motherboard can be quickly removed by simply turning the handles in both directions in the opposite direction. When installing, hold the motherboard and turn the handle with the other hand to drive the first bidirectional screw, so that the two mounting seats move closer to one side of the motherboard to fix it. Then turn the handle on the other side to rotate the second bidirectional screw, so that the other two mounting seats clamp the other two sides of the motherboard to complete the fixation of the motherboard.
[0015] The beneficial effects of this utility model are: when fixing the motherboard, the position of the mounting base on the motherboard is determined by the position of the locking block in the locking slot. As the mounting base moves, the baffle slides after contacting the motherboard. When one end of the locking block is flush with the mounting base, it indicates that a suitable fixing position has been reached, and the handle can be stopped to avoid excessive clamping force of the mounting base on the motherboard.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4This utility model provides a technical solution: it includes a base plate 1, a first mounting groove 3 is formed inside the base plate 1, a first bidirectional screw 4 is rotatably mounted inside the first mounting groove 3, a first slider 5 is threadedly sleeved on the outer side of the first bidirectional screw 4, the first slider 5 is slidably disposed inside the first mounting groove 3, there are two first sliders 5, the two first sliders 5 are symmetrically arranged on both sides of the first mounting groove 3 with the vertical axis of the first bidirectional screw 4 as the center, a mounting seat 8 is provided on the top of the first slider 5, a second mounting groove 19 is formed above the first mounting groove 3, the second mounting groove 19 is perpendicular to the first mounting groove 3, a second bidirectional screw 20 is rotatably mounted inside the second mounting groove 19, a second slider 21 is threaded on the inner and outer sides of the second bidirectional screw 20, there are four mounting seats 8, one of which is located on the top of the second slider 21, a handle 7 is rotatably mounted on the outer side of the base plate 1, the handle 7 is fixedly connected to the first bidirectional screw 4 through a rotating shaft, and the outer side of the handle 7 is provided with an integrally formed anti-slip texture.
[0023] It should be noted that the second mounting groove 19 is located above the first mounting groove 3, and the second mounting groove 19 is perpendicular to the first mounting groove 3. The second mounting groove 19 is not connected to the first mounting groove 3. An auxiliary block is fixedly installed inside the second mounting groove 19. The first bidirectional screw 4 is rotatably inserted into the inside of the auxiliary block. There are two first sliding grooves 2. The two first sliding grooves 2 are symmetrically arranged on both sides of the second sliding groove 17 with the second sliding groove 17 as the axis of symmetry.
[0024] In practice, the workers fix the base plate 1 inside the elevator using bolts 15, securing it to the location where the main board and other electrical control components are to be installed. This location also has threaded holes for bolt 15 threading. After fixing the base plate 1, the main board and other components can be quickly replaced and installed on it. One hand holds the main board on top of the mounting base 8, while the other hand grips the handle 7 to rotate the first bidirectional screw 4. When the first bidirectional screw 4 rotates, the first sliders 5 on both sides of the first bidirectional screw 4 can move relatively closer or further apart within the first mounting groove 3. The two mounting bases 8 move closer together, securing the main board and other components. The main board is then positioned along the first bidirectional screw 3... After the screw 4 is fixed along its length, the handle 7 on the other side of the base plate 1 can be turned to rotate the second bidirectional screw 20, which is located in the middle of the first bidirectional screw 4 and is perpendicular to the first bidirectional screw 4. When the second bidirectional screw 20 rotates, the two second sliders 21 slide along the second bidirectional screw 20 in the second mounting groove 19, causing the other two mounting seats 8 to move closer to each other and clamp the other two sides of the main board, making it easier to fix the new main board after replacement. When the first bidirectional screw 4 and the second bidirectional screw 20 are rotated in sequence, the restriction on the main board in the two perpendicular directions can be released, and the mounting seats 8 set in pairs move away, so that the replacement of the main board can continue.
[0025] See Figure 3 The mounting base 8 is L-shaped. A baffle 9 is slidably connected to one side of the mounting base 8. A snap-fit block 10 is fixedly connected to the center of the baffle 9. A snap-fit groove 11 is opened on the side of the mounting base 8 opposite to the baffle 9. The snap-fit groove 11 is movably snapped into the snap-fit block 10. A compression spring 12 is fixedly connected to one side of the baffle 9. The other end of the compression spring 12 is fixedly connected to the mounting base 8. An anti-slip pad 14 is fixedly connected to the side of the baffle 9 away from the snap-fit block 10. The anti-slip pad 14 is made of rubber. A telescopic component 13 is fixedly installed on one side of the baffle 9. The telescopic end of the telescopic component 13 is fixedly connected to the mounting base 8.
[0026] By setting the mounting base 8, when the motherboard is fixed by the mounting base 8, the position of the mounting base 8 can be identified by the position of the snap-fit block 10 in the snap-fit groove 11. The anti-slip pad 14 contacts the motherboard. As the mounting base 8 moves closer, the anti-slip pad 14 and the baffle 9 slide on the mounting base 8, the compression spring 12 deforms and contracts, and at the same time the snap-fit block 10 slides in the snap-fit groove 11. As the baffle 9 moves, one end of the snap-fit block 10 gradually becomes flush with one side of the mounting base 8. When one end of the snap-fit block 10 is flush with the mounting base 8, it indicates that the clamping force on the motherboard has reached the appropriate position, and the handle 7 can be stopped.
[0027] See Figure 3 and Figure 4 The top of the first slider 5 is fixedly connected to the first connecting plate 6, and the top of the first connecting plate 6 is fixedly connected to the mounting base 8. The top of the base plate 1 is provided with a first sliding groove 2, which communicates with the first mounting groove 3. The first connecting plate 6 is slidably disposed inside the first sliding groove 2. The top of the second slider 21 is fixedly connected to the second connecting plate 16, and the top of the base plate 1 is provided with a second sliding groove 17, which is slidably connected to the second connecting plate 16.
[0028] By setting the first connecting plate 6 and the second connecting plate 16, since the first mounting groove 3 is located below the second mounting groove 19, the height of the first connecting plate 6 is longer than that of the second connecting plate 16. The top of the first connecting plate 6 and the first slider 5 after being connected is flush with the top plane of the second connecting plate 16 and the second slider 21 after being connected, so that the bottoms of the four mounting seats 8 are all at the same plane height, which facilitates the movement of the mounting seats 8.
[0029] See Figure 1 The top of the base plate 1 has a threaded hole, and a bolt 15 is threaded into the threaded hole.
[0030] By providing threaded holes at the four corners of the top of the base plate 1, aligning the threaded holes on the base plate 1 with the threaded holes inside the elevator, the operator can fix the base plate 1 inside the elevator by rotating and inserting the bolts 15 into the threaded holes.
[0031] See Figure 4 The top side of the mounting base 8 is provided with a guide groove 18, and the bottom of the baffle 9 is fixedly connected with a guide slider, which is slidably connected to the guide groove 18.
[0032] By setting the guide groove 18, the guide slider at the bottom of the baffle 9 is slidably connected to the guide groove 18, which facilitates the improvement of the stability of the sliding of the baffle 9.
[0033] Working principle: When using the device, the operator fixes the base plate 1 inside the elevator using bolts 15, securing it to the position where the main board and other electrical control components are to be installed. This position also has threaded holes for bolt 15 thread fixing. After fixing the base plate 1, the main board and other components can be quickly replaced and installed on the base plate 1. One hand holds the main board on top of the mounting base 8, while the other hand holds the handle 7 to rotate the first bidirectional screw 4. When the first bidirectional screw 4 rotates, the first sliders 5 on both sides of the first bidirectional screw 4 can move relatively closer or further apart within the first mounting groove 3. The two mounting bases 8 move closer together, fixing the main board and other components. The main board is then moved along the first... After the first bidirectional screw 4 is fixed in the length direction, the handle 7 on the other side of the base plate 1 can be turned to rotate the second bidirectional screw 20, which is located in the middle of the first bidirectional screw 4 and is perpendicular to the first bidirectional screw 4. When the second bidirectional screw 20 rotates, the two second sliders 21 slide along the second bidirectional screw 20 in the second mounting groove 19, which drives the other two mounting seats 8 to move closer to each other and clamp the other two sides of the main board, making it easier to fix the new main board after replacement. When the first bidirectional screw 4 and the second bidirectional screw 20 are rotated in sequence, the restriction on the main board in the two perpendicular directions can be released, and the mounting seats 8 set in pairs move away, so that the main board can continue to be replaced.
[0034] When the motherboard is fixed by the mounting base 8, the position of the mounting base 8 can be identified by the position of the snap-fit block 10 in the snap-fit groove 11. The anti-slip pad 14 contacts the motherboard. As the mounting base 8 moves closer, the anti-slip pad 14 and the baffle 9 slide on the mounting base 8, the compression spring 12 deforms and contracts, and at the same time the snap-fit block 10 slides in the snap-fit groove 11. As the baffle 9 moves, one end of the snap-fit block 10 gradually becomes flush with one side of the mounting base 8. When one end of the snap-fit block 10 is flush with the mounting base 8, it indicates that the clamping force on the motherboard has reached the appropriate position, and the handle 7 can be stopped.
[0035] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
