Description

Technical Field

[0001] The present invention belongs to the technical field of switch boxes, and particularly relates to a switch box installation structure and method. Background Art

[0002] A switch box is a device used in electrical equipment, usually used to house and protect electrical components such as switches and sockets. Its principle is to achieve the on-off control of current through internal wiring and conductive components. The main functions of the switch box are to provide a safe installation space to prevent electrical components from being damaged by the outside world, and at the same time ensure the normal operation of the circuit. It can also prevent electrical components from being exposed, reduce the risk of electric shock, and increase the reliability and safety of the equipment.

[0003] Chinese Patent No. 201410470630.5 discloses a switch box for installing an intelligent low-voltage metering and billing module. On the bottom cover of this patent, a left live wire terminal compartment A is provided on the left side of the circuit board installation boss, and a live wire wiring groove is provided on the lower side of the circuit board installation boss; the back of the partition bar is installed on the bottom cover, and the left live wire terminal compartment B corresponds to the left live wire terminal compartment A, the right live wire terminal compartment B corresponds to the right live wire terminal compartment A, and the horizontal bar covers the live wire wiring groove; the upper cover is installed on the partition bar, and the left neutral wire terminal compartment B corresponds to the left neutral wire terminal compartment A, the right neutral wire terminal compartment B corresponds to the right neutral wire terminal compartment A, and the neutral wire groove cover corresponds to the neutral wire wiring groove.

[0004] During the installation of the switch box, usually the embedded box body is first fixed on the wall, and then the installation of the remaining switch components is carried out after the subsequent wall decoration is completed. Since there will be a depth difference between the wall decoration and the embedded box body after the wall decoration is completed, and the depth differences are different, it is not convenient for the installation of subsequent switch panels and other components, and the problem of depth difference always occurs in manual embedding; at the same time, it is more troublesome to install the switch bottom plate later, it cannot be stably fixed, and there are often gaps between the switch bottom plate and the wall, which is not only not very beautiful but also has a risk of electric leakage. Summary of the Invention

[0005] To address the deficiencies of the existing technology, the present invention provides a switch box installation structure and method. Through the cooperation of the embedded box and the telescopic frame, when there is a depth difference between the embedded box and the decorated wall surface, the telescopic frame can be controlled to expand and contract to ensure the effective installation of the switch bottom plate, thereby avoiding the impact of the depth difference on the installation of the switch box. At the same time, the installation of the switch bottom plate can be achieved without manually fixing the telescopic frame. Through the structural design of the limit block and the movable cavity, the elastic inclined block is temporarily deformed to clamp the limit block, and at the same time, the limit can be quickly released to facilitate the automatic contraction and installation of the telescopic frame. Through the cooperation of the n-shaped rod-like and the card slot, it can not only prevent the telescopic frame from contracting during the automatic contraction and installation process when the installation square frame abuts against the wall surface, but also prevent the telescopic frame from being pulled out after the telescopic frame has contracted, thereby achieving the automatic seamless installation of the switch box.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] A switch box installation structure includes an embedded box. The front of the embedded box is open and a telescopic frame is movably inserted. The front of the telescopic frame is fixedly installed with a switch bottom plate, and the front of the switch bottom plate is snap-connected with a switch panel.

[0008] On the left and right side walls and the top side wall of the front of the embedded box, an n-shaped groove is commonly penetrated. A limit plate is fixedly installed on the notch of the n-shaped groove. A plurality of sliding holes are penetrated on both the left and right sides of the limit plate, and the telescopic frame is movably inserted into the sliding holes. A wire pipe is fixedly connected to the middle of the bottom of the embedded box.

[0009] Furthermore, the left and right sides and the top of the telescopic frame are all closed structures, and a through groove is penetrated through the top. On the outer edge of the front opening of the telescopic frame, an installation square frame is fixedly provided. Installation plates are fixedly provided inside the left and right sides of the installation square frame, and threaded holes are provided on the installation plates. A plurality of sliding rods are fixedly connected to the back of the left and right sides of the installation square frame. The sliding rods are slidably connected to the corresponding sliding holes, and bumps are fixedly connected to the ends of the sliding rods.

[0010] Even further, a return spring is sleeved on the sliding rod between the bump and the limit plate. On both sides of the bottom of the installation square frame, n-shaped rod-likes are symmetrically and movably installed. A plurality of elastic inclined blocks are evenly fixedly provided on the inner bottom of the n-shaped rod-like, and the inclined direction of the elastic inclined block faces the inside of the embedded box. Limit blocks are symmetrically installed on both sides of the bottom inside the embedded box, and the limit blocks abut against the inner bottom of the n-shaped rod-like.

[0011] Further, the limiting block includes an n-shaped block. Chutes are formed inside both ends of the n-shaped block, and second bumps are slidably connected to the chutes. The second bumps are fixedly connected to second sliding rods; the second sliding rods pass through the ends of the n-shaped block and extend outward, and the ends of the second sliding rods are fixedly connected to a slider together.

[0012] Two activity cavities are symmetrically formed inside the bottom of the embedded box. A pair of guide rods are fixedly connected inside the activity cavities. Through holes on the slider are slidably connected to the corresponding guide rods.

[0013] Further, a pair of guide grooves and a receiving groove are formed in communication with the top of the activity cavity. The receiving groove is in communication with the guide grooves; the second sliding rods are located in the corresponding guide grooves, and the width of the receiving groove is greater than the thickness of the n-shaped block.

[0014] Further, a limiting spring is sleeved on the guide rod, and the limiting spring abuts the slider against the side away from the front of the embedded box; a second return spring is sleeved on the second sliding rod located in the chute.

[0015] Further, the two ends of the n-shaped rod-like member are respectively a first clamping block and a second clamping block. The outer side surface of the first clamping block is a curved surface and the inner side surface is a flat surface; the second clamping block is an L-shaped structure; L-shaped notch openings are symmetrically formed on both sides of the bottom of the installation square frame, and the second clamping block is located in the corresponding L-shaped notch openings and is slidably connected up and down with the L-shaped notch openings.

[0016] A plurality of card slots are evenly formed on the bottom surface of the embedded box directly below the n-shaped rod-like member; the card slots are flat on the side close to the front of the embedded box and are curved on the side away from the front of the embedded box.

[0017] Further, the side length of the installation square frame is greater than the side length of the opening on the wall where the embedded box is located.

[0018] Further, the connecting component of the switch bottom plate is inserted into the front opening of the embedded box; a plurality of second threaded holes are formed on the switch bottom plate, and the second threaded holes and the threaded holes on the corresponding mounting plates are threadedly connected by screws.

[0019] An installation method using the above switch box installation structure includes the following steps:

[0020] S1. Install the embedded box and the telescopic frame on the wall. After decoration, a depth difference is generated between the front of the embedded box and the wall surface. At this time, pull the telescopic frame to pull the telescopic frame out of the wall surface.

[0021] S2. Release the telescopic frame. The elastic inclined clamping block is clamped on the limiting block to limit the telescopic frame. At this time, install the switch bottom plate on the front of the telescopic frame and install the wires.

[0022] S3. After installation, continue to pull the telescopic frame so that the first clamping block of the n-type rod pulls the n-type block to slide on the guiding groove, causing the n-type block to finally fall into the accommodating groove. At this time, the n-type rod and the second clamping block descend synchronously, causing the first clamping block to fall into the clamping groove. Then release the telescopic frame. Under the reset action of the reset spring, the telescopic frame automatically contracts into the embedded box, and the installation square frame abuts against the wall surface.

[0023] S4. At this time, the switch base plate cannot be pulled manually anymore. Snap the switch panel on the front of the switch base plate to complete the installation.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) Through the cooperation of the embedded box and the telescopic frame, when there is a depth difference between the embedded box and the decorated wall surface, the effective installation of the switch base plate can be ensured by controlling the expansion and contraction of the telescopic frame, thus avoiding the influence of the depth difference on the installation of the switch box. At the same time, the installation of the switch base plate can be realized without manually fixing the telescopic frame. Specifically, when the embedded box and the telescopic frame are installed on the wall and a depth difference occurs between the front surface of the embedded box and the wall surface after decoration, pull the telescopic frame at this time. Under the guiding action of the sliding rod, the reset spring is compressed and the telescopic frame is pulled out, causing the telescopic frame to extend out of the wall surface, thus facilitating the installation of the switch base plate and avoiding the influence of the depth difference on the installation of the switch box. At the same time, when the telescopic frame is pulled out, the n-type rod is pulled synchronously. When the telescopic frame extends out of the wall surface, release the telescopic frame. At this time, an elastic inclined clamping block at the bottom of the n-type rod will deform and clamp the limiting block, so that the telescopic frame is temporarily limited and fixed, facilitating the subsequent installation of the switch base plate. The installation of the switch base plate can be realized without manually fixing the telescopic frame.

[0026] (2) Through the structural design of the limiting block and the movable cavity, not only can the elastic inclined clamping block be temporarily deformed to clamp the limiting block, but also the limit can be quickly released to facilitate the automatic contraction and installation of the telescopic frame. Specifically, when the elastic inclined clamping block clamps the limiting block, after the switch base plate and the electric wire are installed, just continue to pull the telescopic frame, so that the first clamping block of the n-type rod pulls the n-type block to slide on the guiding groove, causing the n-type block to finally fall into the accommodating groove. At this time, the n-type block releases the limit on the n-type rod, and the n-type rod descends synchronously. Then release the telescopic frame. At this time, under the reset action of the reset spring, the telescopic frame automatically contracts into the embedded box, and the installation square frame abuts against the wall surface to realize the automatic contraction and installation.

[0027] (3) Through the cooperation of the n-type rod-like structure and the card slot, the present invention can not only prevent the shrinkage of the telescopic frame from being hindered during the automatic shrinkage installation process when the installation box abuts against the wall surface, but also prevent the telescopic frame from being pulled out after the telescopic frame has completed its shrinkage, thereby achieving the automatic seamless installation of the switch box. Specifically, when the telescopic frame automatically shrinks into the embedded box under the reset action of the reset spring, the outer curved surface of the first clamping block will not have a limiting effect on the curved surface of the card slot, and the n-type rod-like structure will continuously rise and fall in a cycle, so that the shrinkage of the telescopic frame will not be hindered during the automatic shrinkage installation process when the installation box abuts against the wall surface. At the same time, after the installation is completed, when the switch bottom plate is pulled, since the inner flat surface of the first clamping block produces a limit with the flat surface of the card slot, the switch bottom plate cannot be pulled, and thus, under the reset action of the reset spring, the installation box closely abuts against the wall surface, achieving the automatic seamless installation of the switch box.

[0040] Embodiment

[0041] As Figures 1 to 8 shown, a switch box installation structure includes an embedded box 100. The front of the embedded box 100 is open and a telescopic frame 400 is movably inserted. The front of the telescopic frame 400 is fixedly installed with a switch bottom plate 300, and a switch panel 200 is snap-connected to the front of the switch bottom plate 300;

[0042] The left and right side walls and the top side wall on the front of the embedded box 100 are jointly and penetratingly provided with an N-shaped groove 120. A limiting plate 500 is hermetically installed on the notch of the N-shaped groove 120. A plurality of sliding holes are penetratingly provided on both the left and right sides of the limiting plate 500, and the telescopic frame 400 is movably inserted into the sliding holes; A wire pipe 110 is fixedly communicated with the middle of the bottom of the embedded box 100.

[0043] The present invention cooperates with the embedded box 100 and the telescopic frame 400. When there is a depth difference between the embedded box 100 and the wall after decoration, the telescopic frame 400 can be controlled to extend and retract to ensure that the switch base plate 300 can be effectively installed, thereby avoiding the influence of the depth difference on the installation of the switch box. At the same time, the switch base plate 300 can be installed without manually fixing the telescopic frame 400; a detailed description will be given later.

[0044] Furthermore, the left and right sides and the top of the telescopic frame 400 are all closed structures, and a through slot 420 is opened through the top; a mounting frame 430 is fixedly provided on the outer edge of the front opening of the telescopic frame 400, and mounting plates 431 are fixedly provided inside the left and right sides of the mounting frame 430, and threaded holes are opened on the mounting plates 431; a plurality of sliding rods 450 are fixedly connected to the back of the left and right sides of the mounting frame 430, and the sliding rods 450 are slidably connected to the corresponding sliding holes and the ends of the sliding rods 450 are fixedly connected to the protrusions 451.

[0045] The sliding of the sliding rod 450 and the corresponding sliding hole changes the telescopic distance of the telescopic frame 400 , and the protrusion 451 plays a limiting role to prevent the sliding rod 450 from being separated from the sliding hole.

[0046] Furthermore, a return spring 460 is sleeved on the sliding rod 450 located between the protrusion 451 and the limit plate 500, and the two sides of the bottom of the installation frame 430 are symmetrically and movably installed with N-type rods 410, and the inner bottom of the N-type rod 410 is evenly fixed with a plurality of elastic inclined blocks 413, and the inclination direction of the elastic inclined blocks 413 is toward the inside of the embedded box 100; the limiting blocks 600 are symmetrically installed on both sides of the bottom of the embedded box 100, and the limiting blocks 600 abut against the inner bottom of the N-type rod 410.

[0047] When the embedded box 100 and the telescopic frame 400 are installed on the wall, when a depth difference is generated between the front face of the embedded box 100 and the wall after decoration, the telescopic frame 400 is pulled at this time, and the return spring 460 is compressed under the guidance of the slide rod 450 and the telescopic frame 400 is pulled out, so that the telescopic frame 400 extends out of the wall, thereby facilitating the installation of the switch base plate 300 and avoiding the influence of the depth difference on the installation of the switch box; at the same time, when the telescopic frame 400 is pulled out, the quasi-n-type rod 410 is pulled synchronously; when the telescopic frame 400 extends out of the wall, the telescopic frame 400 is released, and at this time, an elastic inclined block 413 at the bottom of the quasi-n-type rod 410 will deform and clamp the limit block 600, so that the telescopic frame 400 is temporarily limited and fixed, which is convenient for the subsequent installation of the switch base plate 300, and the installation of the switch base plate 300 can be achieved without manually fixing the telescopic frame 400.

[0048] It should be noted that the elastic inclined clamping block 413 is made of a material with a certain elastic deformation, such as hard rubber, etc. It can not only have a certain degree of deformation, but also perform limit clamping, which will not be described in detail here.

[0049] Furthermore, the limiting block 600 includes an n-shaped block 610. Chutes 611 are opened inside both ends of the n-shaped block 610. A second convex block 631 is slidably connected to the chute 611. The second convex block 631 is fixedly connected to a second sliding rod 630. The second sliding rod 630 passes through the end of the n-shaped block 610 and extends outward, and the ends of the second sliding rods 630 are fixedly connected to a slider 620 together.

[0050] Two movable cavities 150 are symmetrically opened inside the bottom of the embedded box 100. A pair of guide rods 650 are fixedly connected inside the movable cavity 150. A through hole 621 on the slider 620 is slidably connected to the corresponding guide rod 650. The guide rod 650 improves the sliding stability of the slider 620.

[0051] Furthermore, a pair of guide grooves 130 and a receiving groove 140 are communicated and opened at the top of the movable cavity 150. The receiving groove 140 is communicated with the guide groove 130. The second sliding rod 630 is located in the corresponding guide groove 130. The width of the receiving groove 140 is greater than the thickness of the n-shaped block 610.

[0052] Through the structural design of the limiting block 600 and the movable cavity 150, the present invention not only realizes that the elastic inclined clamping block 413 temporarily deforms to clamp the limiting block 600, but also can quickly release the limit to facilitate the automatic contraction and installation of the telescopic frame 400. Specifically, when the elastic inclined clamping block 413 clamps the limiting block 600, after installing the switch bottom plate 300 and the electric wire, just continue to pull the telescopic frame 400, so that the first clamping block 411 of the n-shaped rod 410 pulls the n-shaped block 610 to slide on the guide groove 130, so that the n-shaped block 610 finally falls into the receiving groove 140. At this time, the n-shaped block 610 releases the limit on the n-shaped rod 410, and the n-shaped rod 410 descends synchronously. Then release the telescopic frame 400. At this time, under the reset action of the reset spring 460, the telescopic frame 400 automatically contracts into the embedded box 100, and the installation square frame 430 abuts against the wall surface to realize automatic contraction and installation.

[0053] It should be noted that the n-shaped rod 410 is movably installed on both sides of the bottom of the installation square frame 430, so it can descend synchronously, which will not be described in detail here.

[0054] Furthermore, a limiting spring 660 is sleeved on the guide rod 650. The limiting spring 660 abuts the slider 620 on the side far from the front side of the embedded box 100. A second reset spring 640 is sleeved on the second sliding rod 630 located in the chute 611.

[0055] With the assistance of the limiting spring 660, it is convenient to preliminarily limit the slider 620, thereby preventing the accidental driving of the N-shaped block 610 when the telescopic frame 400 and the N-shaped rod 410 just extend out; with the assistance of the second reset spring 640, when the N-shaped block 610 is moved to directly above the receiving groove 140, the second reset spring 640 can assist in quickly making the N-shaped block 610 fall into the receiving groove 140.

[0056] Furthermore, both ends of the N-shaped rod 410 are respectively a first clamping block 411 and a second clamping block 412. The outer side surface of the first clamping block 411 is a curved surface and the inner side surface is a plane; the second clamping block 412 is an L-shaped structure; symmetrically arranged L-shaped notches 432 are formed on both sides of the bottom of the installation square frame 430, and the second clamping block 412 is located in the corresponding L-shaped notch 432 and is slidably connected up and down with the L-shaped notch 432;

[0057] A plurality of card slots 160 are evenly formed on the bottom surface of the embedded box 100 located directly below the N-shaped rod 410; one side of the card slot 160 close to the front surface of the embedded box 100 is a plane, and the side far from the front surface of the embedded box 100 is a curved surface.

[0058] Through the cooperation of the N-shaped rod 410 and the card slot 160, the present invention can not only prevent the telescopic frame 400 from being blocked during the automatic shrinkage installation process when the installation square frame 430 abuts against the wall surface, but also prevent the telescopic frame 400 from being pulled out after the telescopic frame 400 is completely shrunk, thereby realizing the automatic seamless installation of the switch box; specifically, when the telescopic frame 400 automatically shrinks into the embedded box 100 under the reset action of the reset spring 460, the curved outer side surface of the first clamping block 411 will not produce a limiting effect on the curved surface of the card slot 160, and the N-shaped rod 410 will continuously rise and fall in a cycle, so as to prevent the telescopic frame 400 from being blocked during the automatic shrinkage installation process when the installation square frame 430 abuts against the wall surface; at the same time, after the installation is completed, when the switch bottom plate 300 is pulled again, since the plane inner side surface of the first clamping block 411 produces a limit with the plane of the card slot 160, the switch bottom plate 300 cannot be pulled, so that under the reset action of the reset spring 460, the installation square frame 430 closely abuts against the wall surface, realizing the automatic seamless installation of the switch box.

[0059] It should be noted that the up and down sliding connection of the second clamping block 412 in the corresponding L-shaped notch 432 is not in close fit, so that the N-shaped rod 410 can continuously rise and fall in a cycle. The smoothness of the rise and fall can be improved through the design of specific dimensions, which is a conventional adjustment and will not be described in detail here; and the real-time state can be quickly understood by observing the position of the second clamping block 412 on the L-shaped notch 432.

[0060] Furthermore, the side length of the installation square frame 430 is greater than the side length of the opening on the wall where the embedded box 100 is located. Through this design, the installation square frame 430 is tightly abutted against the wall to achieve seamless installation.

[0061] Furthermore, the connecting component of the switch bottom plate 300 is inserted into the inner part of the front opening of the embedded box 100; a plurality of second threaded holes 310 are provided on the switch bottom plate 300, and the second threaded holes 310 are threadedly connected with the threaded holes on the corresponding mounting plate 431 through screws.

[0062] An installation method using the above switch box installation structure includes the following steps:

[0063] S1. Install the embedded box 100 and the telescopic frame 400 on the wall. After decoration, there is a depth difference between the front of the embedded box 100 and the wall surface. At this time, pull the telescopic frame 400 to pull the telescopic frame 400 out of the wall surface;

[0064] S2. Release the telescopic frame 400, and the elastic inclined clamping block 413 is clamped on the limiting block 600 to limit the telescopic frame 400. At this time, install the switch bottom plate 300 on the front of the telescopic frame 400 and install the wires;

[0065] S3. After installation, continue to pull the telescopic frame 400, so that the first clamping block 411 of the n-shaped rod 410 pulls the n-shaped block 610 to slide on the guide groove 130, so that the n-shaped block 610 finally falls into the accommodating groove 140; at this time, the n-shaped rod 410 and the second clamping block 412 descend synchronously, so that the first clamping block 411 falls into the clamping groove 160; then release the telescopic frame 400, and under the reset action of the reset spring 460, the telescopic frame 400 automatically shrinks into the embedded box 100, and the installation square frame 430 abuts against the wall surface;

[0066] S4. At this time, the switch bottom plate 300 cannot be pulled manually, and the switch panel 200 is buckled on the front of the switch bottom plate 300 to complete the installation.

[0067] When installing the switch bottom plate 300 through the installation method of the present invention, it is not necessary to ensure that the telescopic frame 400 is aligned with the wall surface. It is only necessary to pull the telescopic frame 400 out beyond the wall surface, which not only facilitates the installation of the switch bottom plate 300, but also avoids the problem of subsequent installation gaps.

[0068] 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 inventive concept of the present invention, several improvements and transformations can still be made, and these all belong to the protection scope of the present invention.
