Description

Technical Field

[0002] A switch box is a device used to connect electrical equipment. It is usually made of metal or plastic materials and contains switches, sockets, terminals and other components. Its main principle is to control the opening and closing of the circuit to achieve the flow or cut off of current, thereby controlling the start and stop of electrical equipment. The function of the switch box is to provide safe and convenient electrical connection and control, prevent wires from being exposed, and avoid the risk of electric shock. It is widely used in many fields such as household electrical appliances, industrial equipment, construction, communication equipment, etc., and is an indispensable and important part of electrical engineering.

A left live wire terminal compartment A is provided on the bottom cover of the patent on the left side of the circuit board mounting boss, and a live wire routing groove is provided on the bottom cover on the lower side of the circuit board mounting boss; the back of the partition strip 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 strip covers the live wire routing groove; the upper cover is installed on the partition strip 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 routing groove.

[0004] During the installation of the switch box, the embedded box body is usually fixed to the wall first, and then the remaining switch parts are installed after the subsequent wall decoration is completed. Since there will be a depth difference between the embedded box body and the wall after the wall decoration is completed, and the depth difference is different, it is not convenient for the subsequent installation of components such as the switch panel, and artificial embedding will always have the problem of depth difference; at the same time, it is more troublesome to install the switch base plate later, it cannot be stably fixed, and there will often be a gap between the switch base plate and the wall, which is not beautiful and there is a risk of leakage; and when ordinary switch box parts are damaged, they need to be disassembled with tools such as screwdrivers, but when there is a depth difference between the wall and the embedded box body, it is impossible to flexibly use tools for quick disassembly after installation due to the small space. Summary of the invention

[0005] In order to solve the deficiencies in the prior art, the present invention provides a switch box connection structure and method. The present invention realizes that the depth of the switch box is adjustable when there is a depth difference between the embedded box and the wall after decoration, and also realizes quick disassembly, thereby avoiding the problem that it is impossible to use a screwdriver or other tools for disassembly in a narrow space. The present invention realizes that the switch bottom plate can be effectively installed by controlling the telescopic frame when there is a depth difference between the embedded box and the wall after decoration, thereby avoiding the influence of the depth difference on the installation of the switch box.

[0014] Furthermore, the connecting component of the switch base plate is inserted into the front opening of the embedded box; a plurality of second threaded holes are provided on the switch base plate, and the second threaded holes are threadedly connected with the corresponding threaded holes on the mounting plate through screws.

[0015] A connection method using the switch box connection structure comprises the following steps: S1. Pull apart the telescopic frame and the limit plate, press the T-block into the inside of the T-slot, and insert the plug-in block of the limit plate into the slot of the n-slot, so that one end of the T-block extends out and engages with the bayonet. At this time, the limit plate is engaged with the slot of the n-slot, and then release the telescopic frame; S2. Install the embedded box and telescopic frame on the wall. After decoration, there is a depth difference between the front of the embedded box and the wall. At this time, pull the telescopic frame out of the wall. Then loosen the telescopic frame, and the elastic inclined card block is connected to the limit block to limit the telescopic frame. At this time, install the switch base plate on the front of the telescopic frame and install the wires. 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 guide groove, so that the N-type block finally falls into the accommodating groove; at this time, the N-type rod and the second clamping block are synchronously lowered, so that the first clamping block falls into the clamping groove; then release the telescopic frame, and the telescopic frame automatically shrinks into the embedded box under the reset action of the reset spring, and the installation frame abuts against the wall; at this time, the switch base plate cannot be pulled manually, and the switch panel is buckled on the front of the switch base plate to complete the installation; S4. When disassembly is required, disassemble the switch panel, then push the second card block upwards to release the first card block from the card slot, and then pull the telescopic frame to make the through slot leak out; then reach into the through slot and press the T-block to release the T-block from the bayonet, so as to disengage the limit plate and quickly disassemble.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention achieves adjustable depth of the switch box when there is a depth difference between the embedded box and the wall after decoration through the cooperation of the limit plate and the telescopic frame, and also achieves quick disassembly, thereby avoiding the problem that a screwdriver or other tools cannot be used for disassembly in a narrow space. Specifically, the depth of the switch box is adjustable by sliding the telescopic frame on the limit plate. When disassembly is required, the switch panel is disassembled, and then the telescopic frame is pulled to expose the through groove. Then, the T-block is extended into the through groove and pressed to release the T-block from the bayonet, thereby achieving the detachment of the limit plate, thereby achieving quick disassembly and avoiding the problem that a screwdriver or other tools cannot be used for disassembly in a narrow space.

[0017] (2) The present invention cooperates with the embedded box and the telescopic frame. When there is a depth difference between the embedded box and the wall after decoration, the telescopic frame can be controlled to ensure that the switch base plate can be effectively installed, thereby 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 achieved without manually fixing the telescopic frame. Specifically, when the embedded box and the telescopic frame are installed on the wall, and there is a depth difference between the front face of the embedded box and the wall after decoration, the telescopic frame is pulled at this time, and the return spring is compressed and the telescopic frame is pulled out under the guidance of the sliding rod, so that the telescopic frame extends out of the wall, thereby 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, the telescopic frame is released, and at this time, an elastic inclined block at the bottom of the N-type rod will deform and clamp the limit block, so that the telescopic frame is temporarily limited and fixed, which is convenient for the subsequent installation of the switch base plate. The installation of the switch base plate can be achieved without manually fixing the telescopic frame.

[0018] (3) The present invention realizes temporary deformation of the elastic tilting block to clamp the limit block through the structural design of the limit block and the movable cavity, and can also quickly release the limit, thereby facilitating the automatic retraction and installation of the telescopic frame. Specifically, when the elastic tilting block clamps the limit block, after installing the switch base plate and the wires, it is only necessary to 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 guide groove, so that the N-type block finally falls into the accommodating groove; at this time, the N-type block releases the limit on the N-type rod, and the N-type rod drops synchronously; then the telescopic frame is released, and at this time, the telescopic frame automatically retracts into the embedded box under the resetting action of the resetting spring, and the installation frame abuts against the wall to achieve automatic retraction and installation.

[0019] (4) The present invention can achieve automatic shrinkage installation when the installation frame abuts the wall without hindering the shrinkage of the telescopic frame through the cooperation of the N-type rod and the slot, and at the same time, the telescopic frame cannot be pulled out after the shrinkage is completed, thereby realizing 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 curved outer side surface of the first clamping block will not produce a limiting effect with the curved surface of the slot, and the N-type rod will continue to rise and fall in a cycle, thereby realizing automatic shrinkage installation when the installation frame abuts the wall without hindering the shrinkage of the telescopic frame; at the same time, after the installation is completed, the switch bottom plate is pulled again, because the flat inner side surface of the first clamping block is limited by the flat surface of the slot, so the switch bottom plate can no longer be pulled, so that under the reset action of the reset spring, the installation frame is tightly abutted against the wall, realizing automatic seamless installation of the switch box.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0023] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items.

[0024] Example

[0025] like Figure 1 to Figure 10 As shown, a switch box connection structure includes an embedded box 100, the front of the embedded box 100 is open and a telescopic frame 400 is movably inserted, a switch bottom plate 300 is fixedly installed on the front of the telescopic frame 400, and a switch panel 200 is buckled on the front of the switch bottom plate 300; The left and right side walls and the top side wall of the front side of the embedded box 100 are penetrated by an n-type groove 120, and a limit plate 500 is installed on the groove of the n-type groove 120. The limit plate 500 is an n-type plate and is movably engaged with the groove of the n-type groove 120; a plug-in block 520 is fixedly provided on the top of the back side of the limit plate 500, and a T-shaped groove 530 is provided at the bottom of the plug-in block 520; a T-shaped block 540 is vertically slidably connected in the T-shaped groove 530; a card slot is provided on the top of the interior of the embedded box 100. The stopper 121 is connected with the n-type groove 120; when the limiting plate 500 is engaged with the notch of the n-type groove 120, one end of the T-block 540 extends out and is engaged with the stopper 121; a plurality of sliding holes 510 are provided on the left and right sides of the limiting plate 500, and the telescopic frame 400 is movably inserted on the sliding holes 510. The left and right sides and the top of the telescopic frame 400 are both closed structures, and a through groove 420 is provided on the top; a wire tube 110 is fixedly connected to the middle of the bottom of the embedded box 100.

[0026] The present invention achieves adjustable depth of the switch box when there is a depth difference between the embedded box 100 and the wall after decoration, and also achieves quick disassembly through the cooperation of the limiting plate 500 and the telescopic frame 400, thereby avoiding the problem that a screwdriver or other tools cannot be used for disassembly in a narrow space. Specifically, the adjustable depth of the switch box is achieved by sliding the telescopic frame 400 on the limiting plate 500. At the same time, when disassembly is required, the switch panel 200 is disassembled, and then the telescopic frame 400 is pulled to make the through groove 420 leak out. Then, the T-block 540 is extended into the through groove 420 and the T-block 540 is pressed to release the engagement with the bayonet 121, thereby achieving the detachment of the limiting plate 500, thereby achieving quick disassembly and avoiding the problem that a screwdriver or other tools cannot be used for disassembly in a narrow space.

[0027] It is worth noting that, through the cooperation between 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 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; this will be described in detail later.

[0028] Furthermore, 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 surfaces of the left and right sides of the mounting frame 430, and the sliding rods 450 are slidably connected to the corresponding sliding holes 510 and the ends of the sliding rods 450 are fixedly connected to the protrusions 451.

[0029] The sliding of the sliding rod 450 and the corresponding sliding hole 510 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 510 .

[0030] 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.

[0031] 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.

[0032] It is worth noting that the elastic inclined clamping block 413 is made of a material with a certain elastic deformation, such as hard rubber, etc., which can have a certain degree of deformation and can also perform position limiting clamping, which will not be described in detail here.

[0033] Furthermore, the limit block 600 includes an n-type block 610, and two ends of the n-type block 610 are provided with slide grooves 611, and the slide grooves 611 are slidably connected with second protrusions 631, and the second protrusions 631 are fixedly connected to the second slide rod 630; the second slide rod 630 passes through the end of the n-type block 610 and is arranged outward, and the ends of the second slide rod 630 are fixedly connected to the slider 620; The bottom of the embedded box 100 has two symmetrically arranged movable chambers 150, a pair of guide rods 650 are fixedly connected to the movable chambers 150, and the through holes 621 on the slider 620 are slidably connected to the corresponding guide rods 650. The guide rods 650 improve the sliding stability of the slider 620.

[0034] Furthermore, a pair of guide grooves 130 and a receiving groove 140 are connected to the top of the active cavity 150 , and the receiving groove 140 is connected to the guide groove 130 ; the second slide bar 630 is located in the corresponding guide groove 130 , and the width of the receiving groove 140 is greater than the thickness of the n-type block 610 .

[0035] The present invention realizes temporary deformation of the elastic tilting block 413 to clamp the limit block 600 through the structural design of the limit block 600 and the movable cavity 150, and can quickly release the limit so as to facilitate the automatic retraction and installation of the telescopic frame 400; specifically, when the elastic tilting block 413 clamps the limit block 600, after the switch bottom plate 300 and the wires are installed, it is only necessary to continue to pull the telescopic frame 400, so that the first block 411 of the n-type rod 410 pulls the n-type block 610 to slide on the guide groove 130, so that the n-type block 610 finally falls into the accommodating groove 140; at this time, the n-type block 610 releases the limit on the n-type rod 410, and the n-type rod 410 drops synchronously; then the telescopic frame 400 is released, and at this time, under the resetting action of the resetting spring 460, the telescopic frame 400 automatically retracts into the embedded box 100, and the installation frame 430 is abutted against the wall to achieve automatic retraction and installation.

[0036] It is worth noting that the N-type rods 410 are movably mounted on both sides of the bottom of the frame 430, so they can be lowered synchronously, which will not be described in detail here.

[0037] Furthermore, a limit spring 660 is sleeved on the guide rod 650 , and the limit spring 660 abuts the slider 620 against the side away from the front of the embedded box 100 ; a second return spring 640 is sleeved on the second slider 630 located in the slide groove 611 .

[0038] With the assistance of the limiting spring 660, the slider 620 can be initially limited, thereby preventing the n-type block 610 from accidentally moving when the telescopic frame 400 and the n-type rod 410 are just extended; with the assistance of the second return spring 640, when the n-type block 610 is moved to just above the accommodating groove 140, the second return spring 640 can assist in quickly making the n-type block 610 fall into the accommodating groove 140.

[0039] Furthermore, the two 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 flat surface; the second clamping block 412 is an L-shaped structure; L-shaped slots 432 are symmetrically opened on both sides of the bottom of the installation frame 430, and the second clamping block 412 is located in the corresponding L-shaped slot 432 and is slidably connected to the L-shaped slot 432 up and down; A plurality of slots 160 are evenly arranged on the bottom surface of the embedded box 100 directly below the n-shaped rod 410; the slots 160 are flat on one side close to the front of the embedded box 100 and curved on the other side away from the front of the embedded box 100.

[0040] The present invention cooperates with the n-shaped rod 410 and the card slot 160, so that the contraction of the telescopic frame 400 will not be hindered during the process of the installation frame 430 abutting against the wall to realize automatic contraction installation, and the telescopic frame 400 cannot be pulled out after the contraction is completed, thereby realizing automatic seamless installation of the switch box; specifically, when the telescopic frame 400 automatically contracts into the embedded box 100 under the reset action of the reset spring 460, the curved outer side surface of the first card block 411 will not contact the curved outer side surface of the card slot 160. The surface produces a limiting effect, and the N-shaped rod 410 will continue to rise and fall in a cycle, so that the installation frame 430 can abut against the wall to achieve automatic contraction, and the contraction of the telescopic frame 400 will not be hindered during the installation process; at the same time, after the installation is completed, the switch base plate 300 is pulled again. Since the inner side surface of the plane of the first clamping block 411 and the plane of the clamping groove 160 produce a limiting effect, the switch base plate 300 can no longer be pulled, so that under the resetting action of the resetting spring 460, the installation frame 430 is tightly abutted against the wall, realizing automatic seamless installation of the switch box.

[0041] It is worth noting that the second card block 412 is located in the corresponding L-shaped slot 432 and the up and down sliding connection with the L-shaped slot 432 is not tightly fitted, 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 by designing specific dimensions. This is a routine adjustment and is not described in detail here. In addition, the real-time status can be quickly understood by observing the position of the second card block 412 on the L-shaped slot 432.

[0042] Furthermore, the side length of the installation frame 430 is greater than the side length of the wall opening where the embedded box 100 is located. This design allows the installation frame 430 to be closely attached to the wall, achieving seamless installation.

[0043] Furthermore, the connection component of the switch base plate 300 is inserted into the front opening of the embedded box 100; a plurality of second threaded holes 310 are provided on the switch base plate 300, and the second threaded holes 310 are threadedly connected to the corresponding threaded holes on the mounting plate 431 through screws.

[0044] A connection method using the switch box connection structure comprises the following steps: S1, pull apart the telescopic frame 400 and the limiting plate 500, press the T-shaped block 540 into the inside of the T-shaped slot 530, and insert the plug-in block 520 of the limiting plate 500 into the slot of the n-shaped slot 120, so that one end of the T-shaped block 540 extends out and is engaged with the bayonet 121, at which time the limiting plate 500 is engaged with the slot of the n-shaped slot 120, and then release the telescopic frame 400; S2, the embedded box 100 and the telescopic frame 400 are installed on the wall. After decoration, there is a depth difference between the front of the embedded box 100 and the wall. At this time, the telescopic frame 400 is pulled out of the wall; then the telescopic frame 400 is released, and the elastic inclined block 413 is clamped on the limit block 600 to limit the telescopic frame 400. At this time, the switch base plate 300 is installed on the front of the telescopic frame 400 and the wires are installed; S3, after installation, continue to pull the telescopic frame 400, so that the first clamping block 411 of the n-type rod 410 pulls the n-type block 610 to slide on the guide groove 130, so that the n-type block 610 finally falls into the accommodating groove 140; at this time, the n-type rod 410 and the second clamping block 412 are synchronously lowered, so that the first clamping block 411 falls into the clamping groove 160; then release the telescopic frame 400, and the telescopic frame 400 automatically shrinks into the embedded box 100 under the reset action of the reset spring 460, and the installation frame 430 abuts against the wall; at this time, the switch base plate 300 cannot be pulled manually, and the switch panel 200 is buckled on the front of the switch base plate 300 to complete the installation; S4. When disassembly is required, disassemble the switch panel 200, then push the second clamping block 412 upwards to release the first clamping block 411 from the clamping slot 160, and then pull the telescopic frame 400 to make the through slot 420 leak out; then reach into the through slot 420 and press the T-block 540 to release the T-block 540 from the clamping port 121, so as to achieve the detachment of the limit plate 500, thereby quickly disassembling.

[0045] By using the connection method of the present invention, when installing the switch base plate 300, it is not necessary to ensure that the telescopic frame 400 is aligned with the wall. The telescopic frame 400 only needs to be pulled out beyond the wall, which is convenient for the installation of the switch base plate 300 and avoids the problem of subsequent installation gaps. At the same time, when disassembly is required, the switch panel 200 is disassembled, and then the telescopic frame 400 is pulled to make the through groove 420 leak out; then, by extending into the through groove 420 and pressing the T-block 540, the T-block 540 is released from the bayonet 121, and the limit plate 500 is separated, so that the quick disassembly is avoided, and the problem of being unable to use tools such as a screwdriver for disassembly in a small space is avoided.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
