Description

Technical Field

[0001] The present application relates to the technical field of membrane switches, and in particular to a snap-on and easily detachable membrane switch. Background Art

[0002] Membrane switch is a type of control switch, which is widely used in various equipment and electrical appliances. At present, most membrane switches are generally installed with adhesive when installed with equipment, that is, adhesive is achieved through double-sided tape on the membrane switch or the installation equipment. This method has a high installation efficiency. However, there are also some problems. For example, when the membrane switch fails, it is difficult to quickly disassemble it using double-sided tape, and the outer protective structure of the membrane switch itself will be affected after disassembly. If a new membrane switch is replaced, the residual glue and tape are difficult to clean. If the repaired one is reassembled, the glue or tape after disassembly needs to be reapplied, otherwise there will be problems with unstable assembly. Utility Model Content

[0003] The purpose of the present application is to provide a snap-on and easily detachable membrane switch to solve at least one of the above-mentioned technical problems.

[0004] In order to solve the above technical problems, the present application provides a snap-on and easily detachable membrane switch, comprising a switch body and a mounting base shell;

[0005] A receiving groove adapted to the switch body is formed on the mounting base shell, and the switch body is suitable for being installed in the receiving groove;

[0006] At least one locking hole is provided on the bottom surface of the receiving groove, and at least one locking component is slidably provided on the inner side wall of the locking hole; a locking column suitable for extending into the locking hole is provided on the switch body, and a locking groove is formed on the outer peripheral wall of the locking column;

[0007] The locking assembly comprises an elastic member and a U-shaped main body, wherein the elastic member drives the main body to approach the locking column along the locking hole radially;

[0008] The main body is provided with a clamping block adapted to the clamping slot at one end close to the receiving slot, and an unlocking block at one end away from the receiving slot; the end of the clamping block is wedge-shaped;

[0009] In the above implementation process, during assembly, the user aligns the switch body with the receiving groove on the mounting base shell, and then presses the switch body into the receiving groove. At this time, the locking post on the switch body will extend into the locking hole. In the process of the locking post extending into the locking hole, it first contacts the end of the clamping block. With the cooperation of the wedge-shaped structure of the clamping block, as it is further pressed down, the clamping block moves in the direction away from the locking post. At this time, the elastic member is simultaneously compressed until the clamping block enters the locking groove on the locking post. The elastic member releases its elastic potential energy to make the clamping card snap into the locking groove, thereby locking the switch body and the mounting base shell. When disassembly is required, through The columnar structure extends from one end of the locking hole facing away from the accommodating groove, and by squeezing the unlocking block, the unlocking block is driven to move in the direction away from the locking column. The unlocking block is connected to the locking block, so when the unlocking block moves, it will drive the locking block to move and then separate the locking block from the locking groove, so that the switch body is not restricted, and quick disassembly can be achieved. The solution has a simple structure and can realize automatic and quick assembly of the switch body and the mounting base shell without the need for additional double-sided tape for fixation. It is also simple and quick to disassemble, effectively improving the disassembly and assembly efficiency. At the same time, the impact on the switch body after disassembly and assembly is small, and quick secondary assembly can be performed after maintenance.

[0010] Preferably, the locking holes are provided with four and are respectively arranged near the four corners of the accommodating groove, and the locking components are provided with four corresponding to the locking holes;

[0011] In the above implementation process, the present solution provides locking holes at the four corners of the receiving groove, which can effectively improve the assembly stability of the switch body and the mounting base shell.

[0012] Preferably, a first limiting groove is formed on the inner side wall of the locking hole, and a second limiting groove communicating with the first limiting groove is provided in the first limiting groove on a side away from the axis of the locking hole;

[0013] A limiting column is provided on one side of the main body away from the axis of the locking hole, and the limiting column is suitable for extending into the second limiting groove;

[0014] The main body slides in the first limiting groove;

[0015] In the above implementation process, the second limiting groove can limit the limiting column, while the first limiting groove can limit the main body. The double limiting can further improve the movement stability of the main body, thereby achieving stable buckle locking and unlocking.

[0016] Preferably, the elastic member comprises a spring, one end of the spring abuts against the inner wall of the second limiting groove, and the other end of the spring abuts against one end of the limiting column;

[0017] In the above implementation process, the second limiting groove provides an assembly position for the spring, which can limit the spring; when the main body is squeezed, it moves closer to one side of the spring and then squeezes the spring.

[0018] Preferably, the length of the locking hole is greater than the length of the locking column, and when the locking column is locked into the locking hole, the unlocking block is exposed;

[0019] In the above implementation process, when the switch body and the mounting base shell are installed, the locking column will extend into the locking hole. After it is fully assembled, there is still a certain distance between the end of the locking column and the end of the locking hole, and the unlocking block is located in this distance, so that the inserted convex column structure has space to extend when unlocking it later.

[0020] Preferably, the end of the unlocking block is spherical;

[0021] Preferably, the end of the unlocking block is wedge-shaped;

[0022] In the above implementation process, the end shape of the unlocking block can be in various forms, among which a spherical or wedge-shaped structure can guide the subsequent insertion of the convex column structure for unlocking, thereby facilitating rapid unlocking and disassembly.

[0023] Preferably, a guiding inclined surface is formed around the locking hole on a side of the mounting base shell facing away from the accommodating groove;

[0024] In the above implementation process, the present solution further provides a guiding inclined surface on the outer periphery of the locking opening, which can guide the convex column structure used for unlocking to quickly enter the guiding inclined surface, thereby achieving unlocking.

[0025] Compared with the prior art, the beneficial effects of the present application are as follows: the technical solution provided by the present application has a simple structure, and can realize automatic and rapid assembly of the switch body and the mounting base shell without the need for additional double-sided tape for fixation; and it is also simple and quick to disassemble, which effectively improves the efficiency of disassembly and assembly.

[0039] Example

[0040] Membrane switch is a type of control switch, which is widely used in various equipment and electrical appliances. At present, most membrane switches are generally installed with adhesive when installed with equipment, that is, the adhesive is achieved through the double-sided tape on the membrane switch or the installation equipment. This method has a high installation efficiency. However, there are also some problems. For example, when the membrane switch fails, it is difficult to quickly disassemble it by using the double-sided tape, and the outer protective structure of the membrane switch itself will be affected after disassembly. If a new membrane switch is replaced, the residual glue and tape are difficult to clean. If the repaired one is reassembled, the glue or tape after disassembly needs to be reapplied, otherwise there will be a problem of unstable assembly. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0041] For details, see Figure 1-7 , this embodiment provides a snap-on and easily detachable membrane switch, including a switch body 10 and a mounting base shell 20;

[0042] Specifically, a receiving groove 21 adapted to the switch body 10 is formed on the mounting base shell 20, and the switch body 10 is suitable for being installed in the receiving groove 21;

[0043] Furthermore, at least one locking hole 22 is provided on the bottom surface of the accommodating groove 21, and at least one locking component is slidably provided on the inner wall of the locking hole 22; a locking column 30 suitable for extending into the locking hole 22 is provided on the switch body 10, and a locking groove 31 is formed on the outer peripheral wall of the locking column 30;

[0044] Specifically, the locking assembly includes an elastic member 53 and a U-shaped main body 40, and the elastic member 53 drives the main body 40 to approach the locking column 30 along the radial direction of the locking hole 22;

[0045] Specifically, a clamping block 41 adapted to the clamping groove 31 is provided at one end of the main body 40 close to the accommodating groove 21, and an unlocking block 42 is provided at one end away from the accommodating groove 21; the end of the clamping block is wedge-shaped;

[0046] In the above scheme, when assembling, the user aligns the switch body 10 with the receiving groove 21 on the mounting base shell 20, and then presses the switch body 10 into the receiving groove 21. At this time, the locking column 30 on the switch body 10 will extend into the locking hole 22. In the process of the locking column 30 extending into the locking hole 22, it first contacts the end of the card block. With the cooperation of the wedge-shaped structure of the card block, as it is further pressed down, the card block moves in the direction away from the locking column 30. At this time, the elastic member 53 is synchronously compressed until the card block enters the locking groove 31 on the locking column 30. The elastic member 53 releases the elastic potential energy to make the locking card snap into the locking groove 31, thereby locking the switch body 10 and the mounting base shell 20. When disassembly is required, The columnar structure extends from the end of the positioning hole 22 facing away from the accommodating groove 21, and the unlocking block 42 is driven to move in the direction away from the positioning column 30 by squeezing the unlocking block 42. The unlocking block 42 is connected to the clamping block 41, so when the unlocking block 42 moves, it will also drive the clamping block 41 to move and then the clamping block 41 will be separated from the positioning groove 31, so that the switch body 10 is not restricted, and rapid disassembly can be achieved. The present solution has a simple structure and can realize automatic and rapid assembly of the switch body 10 and the mounting base shell 20 without the need for additional double-sided tape for fixation. It is also simple and quick to disassemble, which effectively improves the disassembly and assembly efficiency. At the same time, the impact on the switch body 10 after disassembly and assembly is small, and rapid secondary assembly can be performed after maintenance.

[0047] For details, see Figure 1 and Figure 5 There are four locking holes 22, which are respectively arranged near the four corners of the accommodating groove 21, and four locking components are correspondingly arranged with the locking holes 22;

[0048] In the above solution, the present solution respectively sets the locking holes 22 at the four corners of the receiving groove 21 , which can effectively improve the assembly stability of the switch body 10 and the mounting base shell 20 .

[0049] It is understandable that when unlocking and disassembling, a U-shaped unlocking structure can be used. Figure 4 The columnar ends of the two U-shaped structures can be respectively inserted into the four positioning holes 22 at the same time, and the unlocking block 42 is squeezed to drive the locking block 41 to move to achieve unlocking.

[0050] Specifically, a first limiting groove 51 is formed on the inner side wall of the locking hole 22, and a second limiting groove 52 communicating with the first limiting groove 51 is provided in the first limiting groove 51 on a side away from the axis of the locking hole 22;

[0051] Furthermore, a limiting column 43 is provided on one side of the main body 40 away from the axis of the locking hole 22, and the limiting column 43 is suitable for extending into the second limiting groove 52;

[0052] Specifically, the main body 40 slides in the first limiting groove 51;

[0053] In the above scheme, the second limiting groove 52 can limit the limiting column 43, while the first limiting groove 51 can limit the main body 40. The double limiting can further improve the movement stability of the main body 40, thereby achieving stable buckle locking and unlocking.

[0054] For details, see Figure 3 The elastic member 53 includes a spring, one end of which abuts against the inner wall of the second limiting groove 52, and the other end of which abuts against one end of the limiting column 43;

[0055] In the above solution, the second limiting groove 52 is an assembly position provided for the spring, which can limit the spring; when the main body 40 is squeezed, it moves closer to one side of the spring and then squeezes the spring.

[0056] Specifically, the length of the locking hole 22 is greater than the length of the locking column 30. When the locking column 30 is locked into the locking hole 22, the unlocking block 42 is exposed.

[0057] In the above scheme, when the switch body 10 and the mounting base shell 20 are installed, the locking column 30 will extend into the locking hole 22. After it is fully assembled, the end of the locking column 30 is still a certain distance away from the end of the locking hole 22, and the unlocking block 42 is located in this distance, so that the inserted convex column structure has space to extend when unlocking is performed later.

[0058] Specifically, in one embodiment, the end of the unlocking block 42 is spherical;

[0059] Specifically, in one embodiment, the end of the unlocking block 42 is wedge-shaped.

[0060] In the above scheme, the end shape of the unlocking block 42 can be in various forms, among which a spherical or wedge-shaped structure can guide the subsequent insertion of the convex column structure for unlocking, thereby facilitating rapid unlocking and disassembly.

[0061] Specifically, a guide inclined surface 221 is formed around the positioning hole 22 on one side of the mounting base shell 20 facing away from the receiving groove 21;

[0062] In the above solution, this solution further provides a guiding inclined surface 221 on the outer periphery of the locking opening, which can guide the convex column structure used for unlocking to quickly enter the guiding inclined surface 221, thereby achieving unlocking.

[0063] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
