Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of switch installation, in particular to an anti-deformation switch panel installation structure. Background Art
[0002] The word switch means to open and close. It also refers to an electronic component that can open a circuit, interrupt the current or make it flow to another circuit. The most common switch is an electromechanical device that can be operated by a person, which has one or more electronic contacts. The "closed" contact means that the electronic contact is conductive and allows current to flow; the "open" switch means that the electronic contact is not conductive and forms an open circuit, which does not allow current to flow.
[0003] The traditional switch structure includes a panel button, a cover, a mounting frame and a switch housing. The switch housing has a contact assembly. The middle of the panel button is hinged on the cover, and its two ends can be raised and lowered to press the moving contact. The cover and the switch housing are respectively mounted on the mounting frame. The mounting frame is also used to be mounted on the dark box. The left and right side panels of the mounting frame have mounting holes for screws to pass through. During installation, the cover is connected to the top of the mounting frame, the switch housing is connected to the bottom of the mounting frame, the switch housing is buried in the dark box, and then the screws are passed through the mounting holes on the mounting frame with a tool, and screwed into the dark box to fix it, and then the panel button is mounted on the cover. When the mounting screws are driven downward, the mounting frame will be pulled and deformed. The middle positions of the left and right side panels of the mounting frame where the mounting holes are provided will be deformed most severely downward. The left and right side panels will present a downward arched structure, and the front and rear end panels of the mounting frame will also warp. Since the face cover, the mounting frame, and the switch housing are installed and connected as one, after the mounting frame is deformed, the face cover and the switch housing will also be deformed together. After the deformation, the following problems exist: 1. Since the mounting frame drives the front and rear ends of the face cover to warp upward, the distance between the two ends of the panel button and the front and rear ends of the face cover will be shortened, and the two ends of the panel button cannot be effectively pressed down, and the panel button has a small swing amplitude. Even when the deformation is serious, the front and rear ends of the face cover will directly press against the two ends of the panel button, resulting in the panel button being unable to be pressed down; 2. Since the mounting frame drives the switch housing to deform downward, the contact assembly in the switch housing will be correspondingly away from the panel button, which will lengthen the triggering stroke between the panel button and the moving contact, resulting in the problem of being unable to touch and press, and the switch product will be scrapped. The greater the torque of the screw, the more serious the deformation of the cover, mounting frame and switch housing. With current technology, the switch cannot be used if the deformation occurs at a torque of 0.6. Utility Model Content
[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides an anti-deformation switch panel installation structure, which can effectively prevent the surface cover and the switch housing seat from being deformed by the installation frame, thereby ensuring that the switch can be used normally.
[0005] The technical solution of the utility model is as follows: an anti-deformation switch panel installation structure comprises a panel button, a face cover, a mounting frame and a switch shell seat, wherein the panel button is mounted on the face cover, and the mounting frame is also used for being mounted on a dark box, and screw through holes are provided on the left and right side plates of the mounting frame, and the switch shell seat is directly connected to the face cover over the mounting frame, and convex edges are provided on the outer edges at both ends of the switch shell seat, and the front and rear end plates of the mounting frame are respectively supported by the convex edges at both ends, and the mounting frame is limited between the convex edges and the bottom surface of the face cover.
[0006] By adopting the above technical solution, since the switch housing base is directly connected to the face cover over the mounting frame, when the mounting frame is deformed during installation, it will not affect the face cover and the switch housing base. Only the mounting frame is deformed independently, and the contact assemblies in the face cover and the switch housing base still maintain good normal triggering.
[0007] Since the convex edges at both ends respectively support the front and rear end plates of the mounting frame, the mounting frame can be prevented from falling off backwards, and the two ends of the mounting frame are not easily deformed and have little influence on the rear switch housing seat.
[0008] Preferably, the inner ring of the mounting frame also has a sunken inner frame edge, the convex edge is supported on the bottom surface of the inner frame edge, and there are also bumps at both ends of the bottom surface of the face cover, and the outer edges of the front and rear end plates of the mounting frame are respectively supported by the bumps at both ends. The inner edge of the mounting frame is supported by the convex edge, and its outer edge is supported by the bumps, and the supporting effect is stable, and both are supported on the front and rear end plates of the mounting frame. Since the front and rear end plates are relatively far away from the screw perforations, the possibility of deformation when the screws are driven in is small.
[0009] Preferably, the outer edges of both ends of the switch housing seat are provided with a plurality of convex edges, and the inner frame edge is also provided with a limit block that can be stuck between two adjacent convex edges, so as to limit the displacement of the installation frame.
[0010] Preferably, the bottom surface of the cover has a concave receiving area, the mounting frame is also installed in the receiving area, and the front and rear end plates and outer edges of the mounting frame also have upwardly concave notches, which can accommodate corresponding protrusions. The mounting frame is partially installed in the receiving area to limit displacement, and the formed notches are also convenient for accommodating protrusions.
[0011] Preferably, a shell cover is further provided on the top of the switch housing seat, and at least one pair of hooks are provided on the top surface of the shell cover, and the hook heads of the pair of hooks are arranged opposite to each other, and a hook groove is provided on the surface cover, and the hook heads of the pair of hooks are respectively hooked on the hook plates on the opposite sides of the hook groove, so as to realize the connection and positioning between the surface cover and the switch housing seat. The surface cover is connected to the top of the switch housing seat.
[0012] Preferably, a connection frame is provided on the bottom surface of the cover, the switch housing is connected to the inner ring of the connection frame, a step block and a lug are provided on the outer ring of the switch housing, a hook platform and a stop platform are provided on the inner ring of the connection frame, the step block abuts on the hook platform to limit the switch housing from being separated downward from the connection frame, and the lug abuts on the bottom of the stop platform to limit the switch housing from being displaced upward. The cover is connected to the outer ring surface of the switch housing.
[0013] Preferably, the upper end surface of the building block is an inclined surface and the lower end surface is a plane. Since the upper end surface of the building block is an inclined surface, it is convenient for the building block to be squeezed upward, and when the building block moves above the hook platform, its lower end surface is a plane and can form a good abutment with the surface of the hook platform.
[0014] Preferably, vertical guide ribs and guide grooves are provided between the connection frame and the switch housing seat, and the connection frame and the switch housing seat cooperate with each other to achieve installation guidance through the guide ribs and the guide grooves.
[0015] Preferably, there are convex points on the left and right side plates and the top surface of the mounting frame, and the convex points on the two side plates correspond to the outer sides of the respective screw holes. When the screw is driven vertically downward to the end, the nail head part will first contact the raised convex point, causing the screw to tilt. Since the screw driving trajectory is tilted, the resistance between it and the threaded hole of the dark box becomes larger, which has a buffering effect on the impact force of the screw driving.
[0016] Preferably, the protrusion is formed by the side plate of the mounting frame protruding upward. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical scheme in this embodiment will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figure 1-10 As shown, an anti-deformation switch panel mounting structure of the utility model comprises a panel button 1, a face cover 2, a mounting frame 3 and a switch shell seat 4. The panel button 1 can be mounted on the face cover 2 in a swinging or floating manner. The mounting frame 3 is also used to be mounted on a dark box. Screw through holes 3a are provided on the left and right side plates 31 and 32 of the mounting frame 3. The switch shell seat 4 is directly connected to the face cover 2 over the mounting frame 3. Both ends of the switch shell seat 4 have convex edges 41 on their outer edges. The convex edges 41 are integrally formed with the switch shell seat 4. The front and rear end plates 33 and 34 of the mounting frame 3 are respectively supported by the convex edges 41 at both ends. The mounting frame 3 is limited between the convex edges 41 and the bottom surface of the face cover 2.
[0031] Specifically, the inner circle of the mounting frame 3 also has a sunken inner frame edge 35, which is integrally formed on the mounting frame 3, and the flange 41 is supported on the bottom surface of the inner frame edge 35. Bumps 21 are also integrally provided at both ends of the bottom surface of the face cover 2, and the outer edges of the front and rear end plates 33 and 34 of the mounting frame 3 are respectively supported by the bumps 21 at both ends.
[0032] Specifically, the outer edges of both ends of the switch housing base 4 are provided with a plurality of protrusions 41 , and the inner frame edge 35 is further provided with a limit block 351 that can be clamped between two adjacent protrusions 41 .
[0033] Specifically, the bottom surface of the cover 2 has a concave accommodating area 22, and the mounting frame 3 is also installed in the accommodating area 22. The outer edges of the front and rear end plates 33 and 34 of the mounting frame 3 also have upwardly concave grooves 3b, and the grooves 3b can accommodate the corresponding protrusions 21.
[0034] Specifically, a shell cover 4a is further provided on the top of the switch shell base 4, and at least a pair of hooks 4a1 are provided on the top surface of the shell cover 4a, and the hook heads 4a11 of the pair of hooks 4a1 are arranged back to back. A hook groove 2a is opened on the surface cover 2, and the hook heads 4a11 of the pair of hooks 4a1 are respectively hooked on the hook plates 2a1 on the opposite sides of the hook groove 2a, so as to realize the connection and positioning between the surface cover 2 and the switch shell base 4.
[0035] Specifically, there is an integrally formed connection frame 23 on the bottom surface of the cover 2, the switch housing seat 4 is connected to the inner circle of the connection frame 23, the outer circle of the switch housing seat 4 is provided with a step block 42 and a lug 43, and the inner circle of the connection frame 23 is provided with a hook platform 231 and a stop platform 232. The step block 42 is pressed against the hook platform 231 to limit the switch housing seat 4 from disengaging from the connection frame 23 downward, and the lug 43 is pressed against the bottom of the stop platform 232 to limit the switch housing seat 4 from moving upward. The upper end surface of the step block 42 is an inclined surface, and the lower end surface is a plane. There are also vertical guide ribs 51 and guide grooves 52 between the connection frame 23 and the switch housing seat 4, and the connection frame 23 and the switch housing seat 4 are installed and guided by the guide ribs 51 and the guide grooves 52. Of course, the cover 2 and the switch housing seat 4 can also be connected with screws. The switch housing seat 4 is square, and has a step block 42 and a lug 43 on each surface, and the step block 42 is located above the lug 43.
[0036] Specifically, there are convex points 3c on the top surfaces of the left and right side plates 31, 32 of the mounting frame 3, and the convex points 3c on the two side plates correspond to the outer sides of the respective screw through holes 3a. The convex points 3c are formed by the upward protrusion of the side plates of the mounting frame 3. The screw through holes 3a are waist-shaped holes, and the convex points 3c are located outside the short aperture of the waist-shaped holes, and the long aperture of the waist-shaped holes extends in the front-to-back direction.
[0037] When installing this product, the switch housing base 4 passes over the mounting frame 3 and is directly connected to the face cover 2. The housing cover 4a is snap-fitted or screw-connected to the switch housing base 4. The hook heads 4a11 of a pair of hooks 4a1 are respectively hooked on the hook plates 2a1 on the opposite sides of the hook groove 2a, so as to realize the connection and positioning between the housing cover 4a and the face cover 2. The switch housing base 4 is connected to the inner circle of the connection frame 23. The block 42 abuts on the hook platform 231 to limit the downward separation of the switch housing base 4 from the connection frame 23, and the lug 43 abuts on the bottom of the stop platform 232 to limit the upward displacement of the switch housing base 4, so as to realize the direct connection and fixation between the switch housing base 4 and the face cover 2.
[0038] The outer edges of the front plate 33 and the rear plate 34 of the mounting frame 3 are supported by the protrusions 21 at both ends of the face cover 2, respectively, and the protrusions 41 at both ends of the switch housing seat 4 are supported on the bottom surfaces of the front and rear ends of the inner frame edge 35, so that the mounting frame 3 can be prevented from being separated backwards, and when the screws are driven into the screw holes 3a, most of the impact force acts on the left plate 31 and the right plate 32 of the mounting frame 3, and the two end plates of the mounting frame 3 are not easily deformed, and the influence on the face cover 2 and the switch housing seat 4 is small;
[0039] The mounting frame 3 is also installed in the accommodating area 22 , the notch 3 b can accommodate the corresponding protrusion 21 , and the limit block 351 on the inner frame edge 35 is also stuck between two adjacent protrusions 41 , which can limit the displacement of the mounting frame 3 .
[0040] When the screw is driven vertically downward from the screw through hole 3a to the end, the nail head part will first hit the raised protrusion, causing the screw to tilt. As the screw driving trajectory tilts, the resistance between it and the threaded hole of the junction box becomes larger, which has a buffering effect on the impact force of the screw driving.
[0041] When the tool drives the screw with a torque of 1.2 or even 1.8, the deformation of this switch product is small and the switch can still be used normally.
[0042] It should be noted that in the description of the present invention, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0043] In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "couple", "connect", and "fix" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
