Description

Technical Field

[0001] This invention relates to the field of electrical distribution cabinet light switch installation technology, and in particular to a positioning device and method for assisting in the installation of electrical distribution cabinet light switches. Background Technology

[0002] The light switches installed on the distribution cabinet door usually have an integrated nameplate. The circular light switch axis position and the corresponding position of the nameplate have threaded holes. During installation, place the nameplate on the front side of the distribution cabinet door at the corresponding light switch installation position, align the threaded hole of the circular light switch on the nameplate with the corresponding circular hole on the distribution cabinet door, and then use fasteners from the back of the cabinet door to pass through the circular hole on the distribution cabinet door and engage with the threaded hole of the light switch and the nameplate to complete the installation of the distribution cabinet light switch.

[0003] The inventors discovered that during the tightening process, the force exerted by the fasteners on the light button causes the sign to shift, resulting in a tilted sign after installation. This not only makes it difficult to meet the requirements for the horizontal and vertical alignment of the light button installation but also affects the appearance of the distribution cabinet. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a positioning device and method for assisting in the installation of light switches in power distribution cabinets. This solves the problem that when installing light switches, the position of the sign changes, resulting in the installed sign being tilted. This not only makes it difficult to meet the requirements for the horizontal and vertical alignment of the light switch installation but also affects the appearance.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, a positioning device for assisting in the installation of light switches in a power distribution cabinet includes multiple sets of positioning plates. Each set of positioning plates has a positioning groove at its bottom, and each set of positioning plates has a sliding track slidably connected to its front side. The track can slide laterally a set distance on the front side of the positioning plate. A cover plate is provided on the front side of the track, and the cover plate is fixedly connected to the positioning plate. Each set of track slides in cooperation with a corresponding sliding rod, and multiple sets of sliding rods are connected and fixed end to end. The positioning plate is pulled relative to the sliding rod to adjust the spacing between the multiple sets of positioning plates, so that the positioning groove engages with the sign to achieve positioning.

[0006] As a further implementation, the positioning plate includes a main positioning plate and multiple sets of secondary positioning plates. Each set of positioning plates has a positioning post on its front side, and the slide rail has a sliding groove. The positioning post and the sliding groove cooperate to limit the lateral sliding distance of the slide rail relative to the positioning plate.

[0007] As a further implementation, the cover plate is shaped like a "Z" and is installed on the side of the slide away from the positioning plate. The cover plate includes a U-shaped structure in the middle, including a top plate and positioning side plates on both sides of the top plate. The inner side of the top plate abuts against the slide rod, and the inner side of the slide rod is used to slide with the outer side of the slide.

[0008] As a further implementation, the slide bar is provided with claws on both sides at one end. The claws are set perpendicular to the slide bar body and are used to lock onto both sides of the slide rail.

[0009] As a further implementation, the slide has a U-shaped structure, including a base plate and limiting side plates on both sides of the base plate. The slide groove is provided on the base plate, and the inner side of the claw contacts and slides with the outer side of the limiting side plate.

[0010] As a further implementation, one end of the limiting side plate is provided with a flange, and the other end is provided with a baffle perpendicularly; the distance between the flanges on the two sets of limiting side plates at one end is greater than the distance between the positioning side plates of the cover plate.

[0011] As a further implementation, the two sets of baffles are slidably engaged with the inner side of the positioning side plate of the cover plate at one end away from each other.

[0012] As a further implementation, the positioning plate is provided with a magnet mounting groove for mounting a magnet.

[0013] As a further implementation, the spacing between the two sets of claws on the slide bar is adapted to the spacing of the limiting side plate.

[0014] Secondly, a positioning method for installing auxiliary switchboard lights in a power distribution cabinet, employing any of the positioning devices described above, includes the following steps: Place the signboard at the light button installation position on the front side of the distribution cabinet door, align the light button with the corresponding round hole on the distribution cabinet door, and then pass the light button through the round opening. Adjust the spacing between the positioning plates in the positioning device so that the positioning groove at the bottom of the positioning plate engages with the sign. Then, tighten the light button from the back of the cabinet door using fasteners to complete the installation of the power distribution cabinet light button.

[0015] The beneficial effects of the present invention are as follows: 1. This invention, through the setting of positioning plates, slides, slide rods, and corresponding cover plate structures, allows the spacing of multiple sets of positioning plates to be adjusted. After adjusting the spacing according to the position of the light button to be installed, the positioning groove engages with the sign. During the tightening of the fasteners on the back of the light button, the sign will not deflect. This solves the problem that when the light button is installed, the sign position changes, and the installed sign is tilted, which not only makes it difficult to meet the requirements of horizontal and vertical installation of the light button, but also affects the appearance.

[0016] 2. The design of the claw, positioning post, slide groove, baffle, and flange in this invention allows the slide to slide laterally within the space covered by the cover plate, ensuring the stability of the device during deployment.

[0017] 3. Magnets can be installed on the positioning plate so that after the positioning plate is positioned, it can be firmly attached to the door of the distribution cabinet, ensuring the structural stability of the positioning device during positioning. Attached Figure Description

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] Example 1 In a typical embodiment of the present invention, reference is made to Figures 1-9 As shown, a positioning device for installing auxiliary light switches in a power distribution cabinet includes multiple sets of positioning plates. Each set of positioning plates has a positioning groove 13 at its bottom. Each set of positioning plates is slidably connected to a slide rail 4 on its front side. The slide rail 4 can slide laterally a set distance on the front side of the positioning plate. A cover plate 5 is provided on the front side of the slide rail 4, and the cover plate 5 is fixedly connected to the positioning plate. Each set of slide rail 4 is slidably engaged with a corresponding slide rod 6, and the multiple sets of slide rods 6 are connected and fixed end to end. The positioning plate is pulled relative to the slide rod 6 to adjust the spacing between the multiple sets of positioning plates, so that the positioning groove 13 engages with the sign 8 to achieve positioning.

[0024] like Figure 1 As shown, the positioning plate includes a main positioning plate 1 and multiple sets of secondary positioning plates. In this embodiment, two sets of secondary positioning plates are provided, namely a first positioning plate 2 and a second positioning plate 3. The main positioning plate 1, the first positioning plate 2 and the second positioning plate 3 are arranged side by side.

[0025] The front structure of each positioning plate is the same, including the corresponding slide rail 4, cover plate 5 and slide rod 6.

[0026] like Figure 6 and Figure 7 As shown, both the main positioning plate 1 and the secondary positioning plate are plate-shaped structures, and each has a positioning groove 13 at the bottom. The shape of the positioning groove is adapted to the shape of the sign 8 and is used to snap the sign into place so that the sign 8 will not rotate or tilt when the light button 7 is tightened.

[0027] Positioning posts 12 are provided at the same height on the front side of the main positioning plate 1 and the secondary positioning plate. The positioning posts 12 are used to cooperate with the slide groove on the slide 4 to restrict the movement position of the slide 4.

[0028] The difference between the main positioning plate 1 and the secondary positioning plate is that the main positioning plate 1 is provided with one or more sets of magnet mounting slots 11. The position of the magnet mounting slots 11 is determined according to the specific situation and is used to install magnets. After the positioning plate is engaged with the sign 8, the positioning plate can be firmly attached to the door of the distribution cabinet, effectively ensuring the stability of the positioning plate when the light button is tightened.

[0029] In other examples, corresponding magnet mounting slots 11 can also be provided on the first positioning plate 2 and the second positioning plate 3 to install magnets.

[0030] A set of cover plates 5 are welded to the front side of each positioning plate, such as Figure 5 As shown, the cover plate is U-shaped and covers the side of the slide away from the positioning plate. The cover plate includes a U-shaped structure in the middle, and the U-shaped structure includes a top plate 52 and positioning side plates 51 on both sides of the top plate. A flange structure is provided at the end of the positioning side plate 51 away from the top plate to form a fixing plate 53. The cover plate 5 is welded to the positioning plate through two sets of fixing plates 53, as shown. Figure 1 As shown.

[0031] It is understandable that the slide is located in front of the positioning plate and is covered by the cover plate at the position of the positioning post 12.

[0032] like Figure 3 As shown, the slide has a U-shaped cross-section and includes a base plate 45 and limiting side plates 44 on both sides of the base plate 45. The slide groove 43 is provided on the base plate 45 and extends along the length of the base plate 45.

[0033] The base plate 45 is attached to the front side of the positioning plate, so that the positioning post passes through the slide groove 43 and is located in the slide groove 43. The slide can slide laterally relative to the positioning plate. The positioning post and the slide groove cooperate to limit the lateral sliding distance of the slide relative to the positioning plate, so that the slide 4 will not detach from the positioning plate.

[0034] like Figure 2 and Figure 3 As shown, one end of the two sets of limiting side plates 44 of the slide 4 is provided with a flange 41, and the other end is provided with a baffle 42 vertically. The baffle 42 is welded to the limiting side plate and is also in the form of a flange.

[0035] like Figure 4 As shown, each set of positioning plates corresponds to a set of slide rods 6. Each set of slide rods 5 has claws 61 on both sides of one end. The claws 61 are set perpendicular to the slide rod body and are used to lock onto both sides of the slide track 4.

[0036] like Figure 1 As shown, the three sets of slide rods 6 are welded end to end to form an integral slide rod 6 structure. The integral slide rod 6 is provided with three sets of claws, which respectively cooperate with the slide tracks on the three sets of positioning plates.

[0037] like Figure 2 As shown, the spacing of the claws 61 on each set of slide bars 6 is adapted to the spacing of the limiting side plate, so that the inner side of the claws 61 contacts and slides with the outer side of the limiting side plate 44.

[0038] The body of the slide bar 6 is a plate-shaped structure. The width of the plate-shaped structure is adapted to the distance between the two limiting side plates on the same slide, so that the inner side of the claw 61 can slide and cooperate with the outer side of the limiting side plate.

[0039] like Figure 1 and Figure 2 As shown, when the three sets of positioning plates are arranged side by side, the claw approaches the left end of the limiting side plate, that is, it abuts against the baffle 42. At this time, the claw can push the baffle 42 to make the slide slide to the left relative to the positioning plate until the positioning post 12 abuts against the right end of the slide groove 43. When the positioning plate is pulled out, that is, the positioning plate is pulled to the left, the claw 61 can slide to the right relative to the limiting side plate 44, that is, move towards the flange 41 until the claw 61 abuts against the flange 41.

[0040] As the positioning plate continues to be pulled out to the left, the positioning post 12 can slide to the left within the slide groove 43 due to the restriction of the flange by the claw 61, until the positioning post 12 is located at the left end of the slide groove 43. During this pulling process, the slide groove can slide to the right relative to the positioning plate, so that the flanged end of the slide 4 is pulled to the right side of the positioning plate. Figure 9 As shown, the maximum pull-out distance of this set of positioning plates stops when the positioning post 12 abuts the left end of the slide groove 43.

[0041] To ensure the smooth operation of the above process, it is necessary to ensure that the inner side of the top plate 52 of the cover plate 5 abuts against the outer side of the slide rod 6 body, and that the inner side of the slide rod body slides in conjunction with the outer side of the slide rail. Figure 2 As shown.

[0042] like Figure 1 As shown, the distance between the flanges on the two sets of limiting side plates 44 at their opposite ends is greater than the distance between the positioning side plates 51 of the cover plate. The two sets of baffles at their opposite ends slide in cooperation with the inner surface of the positioning side plates 51 of the cover plate. Therefore, the distance between the opposite ends of the baffles matches the distance between the positioning side plates 51. With the restriction of the baffles 42, combined with the sliding cooperation of the slide groove 43 and the positioning post 12, the slide 4 can slide in the lateral direction within the space covered by the U-shaped structure of the cover plate 5.

[0043] like Figure 1 As shown, the length of the limiting side plate 44 is the same as the length of the positioning side plate 51, so that when the device is retracted, the left and right ends of the slide and the cover plate are aligned. The baffle 42 fits on the inner side of the left end of the positioning side plate 51, the flange 41 abuts against the right end face of the positioning side plate 51, and the claw 61 abuts against the right side face of the baffle. Figure 2 The positioning pin 12 is fitted at the right end of the slide groove 43.

[0044] When a set of positioning plates is pulled to the left to its maximum extent, as Figure 9 As shown, this is the state after the column positioning plate 1 is pulled out. At this time, the baffle 42 is engaged with the inner side of the right end of the positioning side plate 51, the claw 61 abuts against the left side of the flange, and the positioning column is located at the left end of the slide groove.

[0045] It is understandable that the positioning post 12 is positioned corresponding to the right end of the cover plate 5.

[0046] Understandably, in order to prevent the claw 61 from disengaging from the limiting side plate 44, a set of transverse sliding groove structures can be provided on the outer side of the limiting side plate 44, and a set of sliders can be provided on the inner side of the claw 61. The sliders cooperate with the transverse sliding groove structure so that the claw 61 will not disengage from the limiting side plate 44 after the positioning plate is pulled to the left.

[0047] The purpose of pulling out the positioning plate is to adjust the spacing of the positioning plate according to the spacing of the light buttons to be installed, so that the positioning groove 13 on each positioning plate can engage with the corresponding sign. After engagement, the light buttons can be tightened.

[0048] Example 2 This embodiment provides a positioning method for installing auxiliary switchboard lights in a power distribution cabinet, using the positioning device from Embodiment 1, and includes the following steps: Place the sign 8 at the installation position of the light button 7 on the front side of the distribution cabinet door. Align the threaded holes of the light button 7 and the sign with the corresponding round holes on the distribution cabinet door. Pre-tighten the light button 7 on the back side of the distribution cabinet door with fasteners to achieve initial fixation, so that the integrated sign 8 and light button 7 will not fall off the cabinet door.

[0049] Next, adjust the verticality of signboard 8 to ensure it is not tilted, and then adjust the spacing between the positioning plates in the positioning device, such as... Figure 9 As shown, the positioning groove 13 at the bottom of the positioning plate is then engaged with the sign 8, and the magnet is attached to the cabinet door. Then, the light button is fastened from the back of the cabinet door using fasteners to install the light button of the power distribution cabinet. At this time, the horizontal and vertical alignment of the light button can be ensured when it is fastened.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
