Description

Technical Field

[0001] This invention relates to the field of alarm technology, and in particular to call switches. Background Technology

[0002] Call switches are typically used in alarm systems. Users trigger the call switch to send an alarm signal to the alarm system, thereby enabling the call alarm function.

[0003] The call switch provided by the relevant technology is usually installed on the wall. Pressing the button triggers the micro switch to realize the call alarm. At the same time, the locking spring in the base is engaged in the locking groove on the side wall of the button, so that the call switch is kept in the call alarm state.

[0004] However, locking springs are prone to insufficient elasticity under frequent use, which is detrimental to both locking and unlocking operations. Summary of the Invention

[0011] In some possible implementations, the first locking part includes: an adjacent first wedge surface and a locking surface;

[0012] In the sliding engagement state, the first wedge surface slides into contact with the side wall of the second locking part.

[0013] In the locked state, the locking surface abuts against the bottom wall of the second locking part facing the base.

[0014] In some possible implementations, the second locking part is a wedge block, an arc block, or a cylindrical block.

[0015] In some possible implementations, the slider includes: a connected movable connecting portion and an arm portion;

[0016] The movable connecting part is movably connected to the support member and is limited by the support member in the horizontal direction, so that the sliding member slides in a direction parallel to the panel assembly. Furthermore, the movable connecting part is also connected to the second elastic reset member.

[0017] A second locking part is provided on the wall of the arm facing the button;

[0018] The horizontal direction is perpendicular to the pressing direction of the button.

[0019] In some possible implementations, the base is provided with a limiting groove that limits the end of the arm away from the movable connecting part in the horizontal direction.

[0020] In some possible implementations, the support member includes: a support body and a first limiting block connected to the support body, the first limiting block having a first limiting cavity;

[0021] The movable connecting part is sleeved in the first limiting cavity, and the first limiting cavity limits the movable connecting part in the horizontal direction.

[0022] In some possible implementations, the support member further includes: a second limiting block connected to the support body, wherein the second limiting block and the first limiting block are arranged sequentially along the sliding direction of the slider;

[0023] The movable connecting part is provided with a second limiting cavity, and the second limiting block is sleeved in the second limiting cavity. The second limiting block limits the movable connecting part in the horizontal direction.

[0024] In some possible implementations, the second limiting block has a receiving cavity to accommodate the second elastic reset member;

[0025] One end of the second elastic reset member is connected to or abuts against the second limiting block, and the other end of the second elastic reset member is connected to or abuts against the movable connecting part.

[0026] In some possible implementations, the functional component further includes a circuit board having a switch assembly area and a non-switch assembly area, wherein the microswitch is electrically connected to the circuit board within the switch assembly area;

[0027] The support body is also pressed onto the non-switch assembly area of ​​the circuit board.

[0028] In some possible implementations, the button includes a pressing part and a sliding part, one end of the sliding part being connected to the pressing part, and the other end of the sliding part being movably connected to the base;

[0029] The sliding part is provided with the first locking part;

[0030] The pressing part is used to trigger the micro switch.

[0031] In some possible implementations, the cover includes a cover body and a limiting portion, the limiting portion abutting against the top wall of the slider facing the cover body.

[0032] In some possible implementations, the faceplate body has a button through hole, and the limiting part includes a limiting sleeve, which is coaxially connected with the button through hole to limit the pressing part;

[0033] The sliding member includes a movable connecting part and an arm part connected to each other, and the limiting sleeve simultaneously abuts against the top wall of the movable connecting part and the top wall of the arm part.

[0035] In some possible implementations, the call switch further includes an unlocking element capable of acting on the slider to slide it, thereby releasing the locking connection between the first locking part and the second locking part.

[0036] In some possible implementations, the slider includes: a movable connecting portion and an arm portion connected together, wherein a second wedge surface is provided at the end of the movable connecting portion away from the arm portion;

[0037] The panel assembly has a socket, and the unlocking end of the unlocking member enters the receiving space through the socket and abuts against the second inclined wedge surface;

[0038] The unlocking element is configured such that pressing the unlocking element downwards can drive the sliding element to slide, causing the second locking part to slide away from the first locking part.

[0039] In some possible implementations, the unlocking end of the unlocking element has an unlocking driving surface, which is an inclined plane or an arc-shaped surface.

[0040] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following:

[0041] The call switch provided in this embodiment of the invention allows the user to directly press the button to move it downwards. The downward-moving button slides through a first locking part on its surface, which engages with a second locking part on a slider, driving the slider to slide horizontally until the button reaches a position that triggers a microswitch on the functional component, causing the call switch to activate the alarm. Simultaneously, the first and second locking parts switch from a sliding engagement state to a locked state, with the first locking part being locked by the second locking part. This, in turn, locks the button by the slider, keeping the call switch in the alarm activation state. The slider is movably connected to a support member, allowing it to slide under the support of the support member. A second elastic reset member is located between the slider and the support member to facilitate the reset movement of the slider.

[0042] As can be seen, the call switch provided in this embodiment of the invention uses a slider linked to the button as a locking component. The sliding of the slider during locking is driven by the pressing motion of the button, which is a novel locking method. Furthermore, this linkage method allows the slider to be set as a rigid component, eliminating the possibility of locking or unlocking failure due to insufficient elasticity, thus ensuring the reliability of the button's locking or unlocking operation and fundamentally solving the technical problems existing in related technologies.

[0076] The accompanying drawings have illustrated specific embodiments of the invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0077] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0078] The directional terms used in the embodiments of this invention, such as "upper," "lower," and "side," are generally... Figure 1 and Figure 2 The relative positions shown are based on the given information, and these directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged. In this embodiment of the invention, the position of the panel is defined as "up," and the position of the base is defined as "down."

[0079] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0080] The call switch provided by the relevant technology is usually installed on the wall. Pressing the button triggers the micro switch to realize the call alarm. At the same time, the locking spring in the base is engaged in the locking groove on the side wall of the button, so that the call switch is kept in the call alarm state.

[0081] However, locking springs are prone to insufficient elasticity under frequent use, which is detrimental to both locking and unlocking operations.

[0082] For example, when unlocking the locking spring, the end of the unlocking component rotates to engage the free end of the locking spring. If the locking spring's elasticity is insufficient, the unlocking component may be unable to effectively engage the free end, resulting in a failure to engage. Alternatively, when locking using the locking spring, the locking spring relies on its elasticity to return to its original position within the locking groove on the button's side wall. If the locking spring's elasticity is insufficient, it may be difficult for it to move into the locking groove, causing a locking failure.

[0083] Regarding the technical problems existing in related technologies, such as Figure 1 -Appendix Figure 2 As shown, an embodiment of the present invention provides a call switch, which includes: a panel assembly 1, a base assembly 2, a trigger assembly 3, a locking assembly 4, and a functional assembly 5. The panel assembly 1 includes a face cover 12, the base assembly 2 includes a base 21, and the trigger assembly 3, the locking assembly 4, and the functional assembly 5 are all located within the accommodating space formed by the face cover 12 and the base 21.

[0084] Further details combined with appendix Figure 3 As shown, the trigger component 3 includes a button 31 and a first elastic reset member 32. The button 31 is movably connected to the base 21 and passes through the panel component 1. The button 31 has a first locking part 311. The first elastic reset member 32 is located between the button 31 and the base 21.

[0085] The locking assembly 4 includes a slider 41, a support 42, and a second elastic reset member 43. The support 42 is fixed inside the base 21, the slider 41 is movably connected to the support 42, the second elastic reset member 43 is located between the slider 41 and the support 42, and the slider 41 has a second locking part 411.

[0086] The call switch provided in this embodiment of the invention is configured such that the button 31 can be pressed to switch the first locking part 311 and the second locking part 411 from a sliding engagement state to a locked state, and the button 31 triggers the micro switch 51 on the functional component 5 in the locked state.

[0087] In this embodiment of the invention, the movement direction of button 31 is defined as the vertical direction, so the pressing direction of button 31 can be considered as the vertically downward direction; the sliding direction of slider 41 is defined as the horizontal direction, that is, parallel to panel assembly 1 and perpendicular to the movement direction of button 31.

[0088] In application, the call switch provided in this embodiment of the invention allows the user to directly press button 31 to move it downwards. The downward-moving button 31 slides through a first locking part 311 on its surface, which engages with a second locking part 411 on the slider 41. This drives the slider 41 to slide horizontally until the button 31 moves downwards to the position triggering microswitch 51 on the functional component 5, causing the call switch to activate the alarm. Simultaneously, the first locking part 311 and the second locking part 411 switch from a sliding engagement state to a locked state. The first locking part 311 is locked by the second locking part 411, which in turn locks the button 31 by the slider 41, thus keeping the call switch in the alarm activation state. The slider 41 is movably connected to the support 42, allowing it to slide under the support of the support 42. The second elastic reset member 43 is located between the slider 41 and the support 42 to facilitate the reset movement of the slider 41. The second locking part 411 resets to a certain extent after sliding away from the first locking part 311, so that the second locking part 411 abuts against the top wall of the first locking part 311.

[0089] As can be seen, the call switch provided in this embodiment of the invention uses a slider 41 linked to the button 31 as a locking component. The sliding of the slider 41 during locking is driven by the pressing motion of the button 31, which is a novel locking method. Furthermore, this linkage method allows the slider 41 to be set as a rigid component, eliminating the possibility of locking or unlocking failure due to insufficient elasticity, thus ensuring the reliability of the locking or unlocking operation of the button 31 and fundamentally solving the technical problems existing in related technologies.

[0090] The structure and function of each component involved in this call switch are illustrated below:

[0091] As attached Figure 3 As shown, the button 31 is provided with a first locking part 311, and the locking component 4 is provided with a second locking part 411. The cooperation between the first locking part 311 and the second locking part 411 includes a sliding cooperation state and a locking state.

[0092] In some examples, as shown in the appendix Figure 4As shown, the first locking part 311 includes: a first wedge surface 3111 and a locking surface 3112 adjacent to each other; in the sliding engagement state of the first locking part 311 and the second locking part 411, the first wedge surface 3111 slides into contact with the side wall of the second locking part 411; in the locked state of the first locking part 311 and the second locking part 411, the locking surface 3112 abuts against the bottom wall of the second locking part 411 facing the base 21.

[0093] The first wedge surface 3111 is an inclined plane, with its upper end connected to the locking surface 3112 and its lower end extending to the lower end of the first locking portion 311. The first locking portion 311 can be, for example, a wedge-shaped block, wherein the locking surface 3112 is located at its top end and can be set as a plane.

[0094] Appendix Figure 3 The sliding engagement state between the first locking part 311 and the second locking part 411 is illustrated in the attached figure. Figure 3 As shown, in the sliding engagement state, the first wedge surface 3111 slides into the side wall of the second locking part 411, and the button 31 is not locked and can be pressed down.

[0095] When button 31 is pressed down, the first locking part 311 moves downward and drives the second locking part 411 to slide horizontally away from the first locking part 311 (to the right) through its first wedge surface 3111, and then the slider 41 slides horizontally to the right as a whole.

[0096] When button 31 moves downwards to its position and triggers micro switch 51, the second locking part 411 slides away from the first locking part 311. Since the second locking part 411 is no longer stopped by the first locking part 311, it will reset under the elastic force of the second elastic reset member 43, that is, move to the left.

[0097] Appendix Figure 5 The example illustrates the locked state between the first locking part 311 and the second locking part 411, as shown in the attached figure. Figure 5 As shown, the second locking part 411, which moves a certain distance to the left, simultaneously abuts against the locking surface 3112 of the first locking part 311 and the side wall of the button 31. Thus, the first locking part 311 is blocked by the second locking part 411 and cannot move upwards to reset. Simultaneously, the second locking part 411 is blocked by the side wall of the button 31 (i.e., the side wall of the sliding part 3102) and cannot continue to move to the left to reset, thereby locking the first locking part 311 and the second locking part 411 together. In this locked state, the button 31 remains in the position that triggers the micro switch 51, keeping the call switch in the call alarm state.

[0098] In this embodiment of the invention, the second locking part 411 is a wedge-shaped block, an arc-shaped block, or a cylindrical block (see...). Figure 3 or Figure 4 The above-described structure of the second locking part 411 can be effectively driven to slide by the first locking part 311.

[0099] The side wall of the second locking part 411 is used to slide with the first wedge surface 3111 of the first locking part 311, and the bottom wall of the second locking part 411 facing the base 21 is used to lock with the locking surface 3112 of the first locking part 311.

[0100] For example, if the second locking part 411 is a wedge-shaped block, then the side of the second locking part 411 is provided with an inclined wedge surface that matches the first inclined wedge surface 3111, and the bottom of the second locking part 411 is provided with a locking surface that abuts against the locking surface 3112. The locking surface can be a plane or an arc surface.

[0101] For example, the second locking part 411 is an arc-shaped block or a cylindrical block (wherein, Figure 3 and Figure 4 (Example: a cylindrical block) Then, the arc-shaped or circular arc-shaped sidewall of the second locking part 411 slides in engagement with the first inclined wedge surface 3111, and the arc-shaped or circular arc-shaped bottom wall of the second locking part 411 abuts against the locking surface 3112.

[0102] In some examples, the second locking part 411 can be a cylindrical block, which not only makes the sliding process of the slider 41 smoother, but also simplifies the molding process of the slider 41 based on its simple structure.

[0103] See Figure 6 , Figure 7 and Figure 8 An example of a slider 41 is provided, comprising: a movable connecting portion 4101 and an arm portion 4102 connected to each other; the movable connecting portion 4101 is movably connected to a support member 42 and is limited in the horizontal direction by the support member 42, such that the slider 41 slides in a direction parallel to the panel assembly 1, and the movable connecting portion 4101 is also connected to a second elastic reset member 43; a second locking portion 411 is provided on the wall of the arm portion 4102 facing the button 31. The aforementioned horizontal direction is perpendicular to the pressing direction of the button 31.

[0104] The movable connecting part 4101 is used to movably connect to the support member 42, so that the sliding member 41 is supported and limited by the support member 42. The arm part 4102 is provided with a second locking part 411 so as to deliver the second locking part 411 to the position corresponding to the first locking part 311.

[0105] For example, as shown in the appendix Figure 8As shown, the arm 4102 includes a rod body and an extension rod connected to the lower part of the rod body. The second locking part 411 is connected to the extension rod. This arrangement makes the assembly of the sliding member 41 and the support member 42 more compact, thereby reducing the assembly volume and facilitating the miniaturization of the call switch.

[0106] In some examples, as shown in the appendix Figure 8 As shown, the width of the movable connecting portion 4101 is greater than the width of the arm portion 4102, and the arm portion 4102 can be connected to one side of the movable connecting portion 4101. The direction of the aforementioned width is perpendicular to the sliding direction of the slider 41.

[0107] For example, the movable connecting part 4101 is a rectangular block, and the arm part 4102 is a rod, as shown in the attached figure. Figure 6 As shown, the movable connecting part 4101 and the button 31 are arranged side by side along the sliding direction of the slider 41, and the arm part 4102 is located on one side of the button 31 along a direction perpendicular to the sliding direction of the slider 41.

[0108] The slider 41 is limited by the support 42 based on its movable connection 4101, ensuring that the slider 41 can only move along its sliding direction, while avoiding displacement in other directions. Further, see... Figure 3 It can be seen that a limiting groove 211 is provided on the base 21, and the limiting groove 211 limits the end of the arm 4102 away from the movable connecting part 4101 in the horizontal direction.

[0109] The end of the arm 4102 that is away from the movable connecting part 4101 extends into the limiting groove 211. The limiting groove 211 allows the arm 4102 to slide horizontally along the sliding direction of the slider 41, while preventing it from being displaced in other directions, such as in a direction perpendicular to the sliding direction of the slider 41.

[0110] In some examples, a bracket is provided on the base 21, and a limiting groove 211 is formed on the bracket to ensure that the position of the limiting groove 211 in the base 21 satisfies the requirement that the sliding member 41 be arranged horizontally.

[0111] As mentioned above, the movable connecting portion 4101 of the slider 41 is limited by the support member 42. The following is an exemplary description of this limiting method:

[0112] As attached Figure 7 and attached Figure 8 As shown, the support member 42 includes: a support body 420 and a first limiting block 421 connected to the support body 420. The first limiting block 421 has a first limiting cavity 4210. The movable connecting part 4101 is sleeved in the first limiting cavity 4210, and the first limiting cavity 4210 limits the movable connecting part 4101 in the horizontal direction.

[0113] The support body 420 is frame-shaped, and its side walls are formed to form a first limiting cavity 4210. The structure of the first limiting cavity 4210 is adapted to the structure of the movable connecting part 4101, so that the movable connecting part 4101 is effectively limited by the first limiting cavity 4210 and can only slide horizontally along the sliding direction of the slider 41, and will not slide horizontally in other directions.

[0114] Understandably, the side of the support body 420 facing the button 31 can be designed to be open (i.e., without a sidewall at that location), or the side can be provided with a sidewall having a through hole to accommodate the movable connection 4101.

[0115] Furthermore, as shown in the appendix Figure 7 and attached Figure 8 As shown, the support member 42 further includes a second limiting block 422 connected to the support body 420. The second limiting block 422 and the first limiting block 421 are arranged sequentially along the sliding direction of the sliding member 41. The movable connecting part 4101 is provided with a second limiting cavity 4103, and the second limiting block 422 is fitted into the second limiting cavity 4103, thereby limiting the movable connecting part 4101 in the horizontal direction.

[0116] The movable connecting part 4101 can be configured as a frame with an open lower end to form a second limiting cavity 4103 with a lower opening, and the second limiting block 422 is assembled into the interior of the second limiting cavity 4103 through the lower opening.

[0117] The end of the second limiting block 422 facing the first limiting block 421 can be located outside the first limiting cavity 4210 or can extend into the interior of the first limiting cavity 4210.

[0118] The movable connecting part 4101 is sleeved inside the first limiting cavity 4210 of the first limiting block 421. At the same time, the movable connecting part 4101 is also sleeved outside the second limiting block 422 through its second limiting cavity 4103. In fact, the limiting function of the second limiting block 422 is the same as that of the first limiting block 421. By further adding the second limiting block 422, the limiting effect on the movable connecting part 4101 is improved and its smooth movement is more stable and reliable.

[0119] In some examples, the support body 420 is flat, and the first limiting block 421 and the second limiting block 422 are rectangular frames with different widths and coaxially connected.

[0120] Furthermore, combined Figure 8 , Figure 9 and Figure 10It is known that the second limiting block 422 has a receiving cavity 4220 to accommodate the second elastic reset member 43; one end of the second elastic reset member 43 is connected to or abuts against the second limiting block 422, and the other end of the second elastic reset member 43 is connected to or abuts against the movable connecting part 4101.

[0121] The length direction of the accommodating cavity 4220 is the same as the direction of the elastic force of the second elastic reset member 43 acting on the slider 41, which is parallel to the sliding direction of the slider 41. The second elastic reset member 43 applies an elastic force to the slider 41, which is beneficial to make the slider 41 reset.

[0122] The second elastic reset member 43 can be an elastic structure such as a tension spring or a compression spring. For example, the second elastic reset member 43 is a compression spring.

[0123] The second elastic reset member 43 can be assembled between the second limiting block 422 and the movable connecting part 4101 in the following manner: the first end of the second elastic reset member 43 abuts against or connects with the corresponding end of the second limiting cavity 4103. During connection, a connecting sleeve or connecting protrusion can be provided at the corresponding end of the second limiting cavity 4103 to engage with the first end of the second elastic reset member 43.

Figure 9 An example is provided at the corresponding end of the second limiting cavity 4103, which is provided with a connecting protrusion.

[0124] The second end of the second elastic reset member 43 abuts against or connects to the corresponding end of the receiving cavity 4220 of the second limiting block 422. During connection, a connecting sleeve or connecting protrusion can be provided at the corresponding end of the receiving cavity 4220 to engage with the second end of the second elastic reset member 43. (The attached text is incomplete and requires further context.) Figure 9 The example illustrates that the second end of the second elastic reset member 43 abuts against the corresponding end of the second limiting cavity 4103.

[0125] When the slider 41 is in the initial position, the second locking part 411 and the first locking part 311 are in a sliding engagement manner, and the second elastic reset part 43 is in a natural state.

[0126] When the slider 41 is driven to a smooth movement by the button 31, the second elastic reset member 43 is compressed and stores a certain amount of elastic potential energy. At the instant when the second locking part 411 separates from the first locking part 311, the smooth displacement of the slider 41 reaches its maximum, and at the same time, the elastic potential energy reaches its maximum value.

[0127] When the second locking part 411 and the first locking part 311 are locked together, the sliding member 41 performs a slight reset movement. The second elastic reset member 43 releases a certain amount of elastic potential energy, but not completely. The remaining elastic potential energy is used to reset the sliding member 41 to the initial position.

[0128] Understandably, the micro switch 51 typically includes two types: the first type of micro switch 51 is activated when its trigger terminal is pressed and then quickly resets; the second type of micro switch 51 is activated when its trigger terminal is pressed and requires pressing again to reset. Both types of micro switches 51 are applicable to the embodiments of the present invention. The micro switch 51 is subordinate to functional component 5.

[0129] Understandably, functional component 5 also includes a circuit board 52, on which a control circuit is provided. This control circuit is electrically connected to a micro switch 51. After the micro switch 51 is pressed and turned on, the control circuit receives the call alarm signal and sends the call alarm signal to the terminal device. The terminal device may be, for example, a pager, which, upon receiving the call alarm signal, can make an audible call to achieve the alarm purpose.

[0130] In some examples, the base 21 has a positioning groove that is adapted to the structure of the circuit board 52. The circuit board 52 is accommodated and positioned in the positioning groove. Furthermore, the circuit board 52 can be connected to the corresponding position on the base 21 by fasteners, such as screws, thereby achieving stable placement in the base 21.

[0131] In addition to maintaining an electrical connection with the circuit board 52, the micro switch 51 is also mounted on the circuit board 52. For example, the circuit board 52 has a recessed hole, and the bottom of the micro switch 51 has a protruding post, so that the protruding post is inserted into the recessed hole, thereby achieving stable placement of the micro switch 51 on the circuit board 52.

[0132] In some examples, embodiments of the present invention may use a first type of micro switch 51, as shown in the attached figure. Figure 6 As shown, the trigger end of this type of micro switch 51 is generally designed as an elastic sheet 510. The first end of the elastic sheet 510 is connected to the outer wall of the micro switch 51, and the second end of the elastic sheet 510 is upturned and located above the micro switch 51. The micro switch 51 has a trigger head located in the gap between the elastic sheet 510 and the micro switch 51, close to the first end of the elastic sheet 510. The upturned second end of the elastic sheet 510 interacts with the trigger portion to be pressed down and triggered.

[0133] In some examples, the circuit board 52 has a switch assembly area and a non-switch assembly area. The micro switch 51 is electrically connected to the circuit board 52 in the switch assembly area. The support body 420 is also pressed onto the non-switch assembly area of ​​the circuit board 52. This arrangement not only makes the assembly of the support 42 in the base 21 more compact, but also protects the non-switch assembly area of ​​the circuit board 52.

[0134] For example, the support body 420 is flat and is laid flat on the non-switch assembly area of ​​the circuit board 52. The two are connected by screws, so that the support 42 can be fixedly arranged in the base 21.

[0135] As attached Figure 6 As shown, button 31 includes: a pressing part 3101 and a sliding part 3102. One end of the sliding part 3102 is connected to the pressing part 3101, and the other end of the sliding part 3102 is movably connected to the base 21. A first locking part 311 is provided on the sliding part 3102. The pressing part 3101 is used to trigger the micro switch 51.

[0136] The pressing part 3101 of the button 31 passes through the button through hole 13 on the panel assembly 1. It is designed to be pressed by the user. For example, the pressing part 3101 is a common circular disc. Furthermore, in order to improve the pressing feel, rough bumps or textured structures can be provided on the top wall of the pressing part 3101. Alternatively, a soft coating can be provided on the top wall of the pressing part 3101.

[0137] In some examples, a stop rib may be provided on the top wall of the cover 12 of the panel assembly 1. This stop rib is coaxially connected to the button through hole 13. The stop rib is used to stop the pressing part 3101 and prevent it from moving excessively upward and disengaging from the cover 12. Furthermore, this stop rib may also be fitted inside the button through hole 13 of the panel 11, so that the cover 12 and the panel 11 mutually limit each other in the horizontal direction.

[0138] The bottom wall at the corresponding position of the pressing part 3101 can be used as a trigger to trigger the trigger end of the micro switch 51, or a separate trigger can be connected to the side of the pressing part 3101 facing the base 21.

[0139] When the button 31 is not pressed, the trigger part of the pressing part 3101 is spaced apart from the trigger end of the micro switch 51. After the button 31 is pressed and moved to a certain distance, the bottom of the trigger part of the pressing part 3101 abuts against the trigger end of the micro switch 51 and presses down the trigger end, thereby triggering the micro switch 51.

[0140] Button 31 is movably connected to base 21 by its sliding part 3102, so that button 31 moves in the vertical direction. When the user presses the pressing part 3101, button 31 moves downward and triggers micro switch 51. When button 31 is reset, it moves upward.

[0141] In some examples, the sliding part 3102 is a hollow structure and is movably connected to the base 21. For example, Figure 3As shown, a connecting sleeve 212 is provided at a corresponding position on the base 21, and the sliding part 3102 is slidably connected to the connecting sleeve 212, so that the sliding part 3102 can slide under the guidance of the connecting sleeve 212.

[0142] For example, the sliding part 3102 is sleeve-shaped, and the connecting sleeve 212 is adapted to the structure of the sliding part 3102. The sliding part 3102 can be sleeved on the outside of the connecting sleeve 212, or the connecting sleeve 212 can be sleeved on the outside of the sliding part 3102. For example, both have a circular outline.

[0143] By utilizing the sliding engagement of the connecting sleeve 212 with the sliding part 3102 and guiding the sliding part 3102 to slide up and down, the sliding part 3102 can achieve the pressing movement of the sliding part 3102 relative to the base 21. Furthermore, the connecting sleeve 212 also helps to position the sliding part 3102, so that it can only reciprocate along the pressing direction (i.e., the vertical direction) and cannot be displaced in the horizontal direction.

[0144] Furthermore, as shown in the appendix Figure 6 As shown, button 31 also includes a stop portion 3103, which is connected to the side of sliding portion 3102 and is located on one side of first locking portion 311.

[0145] As attached Figure 8 As shown, the arm 4102 includes a rod body and an extension rod connected to the lower part of the rod body, and the second locking part 411 is connected to the extension rod.

[0146] Although the probability of the slider 41 slipping excessively is very low, when the button 31 is suddenly subjected to a large impact force, the slider 41 may slip excessively due to the impact force. By setting the first locking part 311 to abut against the side of the extension rod of the arm 4102, the excessive slipping of the slider 41 can be effectively prevented.

[0147] In this embodiment of the invention, the first locking part 311 can be a wedge-shaped block, and the first locking part 311 can be connected to the lower end of the outer side wall of the sliding part 3102. A gap cavity is provided between the first locking part 311 and the side wall of the side portion of the base 21, which is used to accommodate the smoothly moving second locking part 411 to prevent the second locking part 411 from interfering with the movement.

[0148] As attached Figure 3 As shown, one end of the first elastic reset member 32 abuts against or is connected to the button 31, and the other end of the first elastic reset member 32 abuts against or is connected to the base 21; the first elastic reset member 32 is configured to cause the button 31 to perform a reset movement.

[0149] The first elastic reset member 32 can be an elastic structure such as a tension spring or a compression spring. For example, the first elastic reset member 32 is a compression spring. The direction of the elastic force of the first elastic reset member 32 acting on the button 31 is parallel to the pressing direction of the button 31. The first elastic reset member 32 applies an elastic force to the button 31, which can cause the button 31 or the slider 41 to slide away from the micro switch 51, so as to realize the reset of the button 31.

[0150] For example, as shown in the appendix Figure 3 As shown, a connecting sleeve or connecting protrusion is provided in the inner cavity of the connecting sleeve 212 on the base 21 to engage with the lower end of the first elastic reset member 32. The upper end of the first elastic reset member 32 is connected to or abuts against the inner cavity of the sliding part 3102. For example, a partition or a ring of stop steps is provided in the inner cavity of the sliding part 3102, so that the upper end of the first elastic reset member 32 extends into the inner cavity of the sliding part 3102 and abuts or connects with the partition or stop steps.

[0151] In some implementations, such as the appendix Figure 10 As shown, the face cover 12 includes: a face cover body 120 and a limiting part 121, which are further combined with... Figure 3 It can be seen that the limiting part 121 abuts against the top wall of the sliding member 41 facing the cover body 120.

[0152] By having the bottom wall of the limiting part 121 abut against the top wall of the sliding member 41 facing the cover body 120, the sliding member 41 can be limited in the vertical direction to prevent the sliding member 41 from displacing in the vertical direction.

[0153] In some examples, as shown in the appendix Figure 10 As shown, the faceplate body 120 has a button through hole 13, and the limiting part 121 includes a limiting sleeve 1211, which is coaxially connected with the button through hole 13 to limit the pressing part 3101; the sliding member 41 includes a movable connecting part 4101 and an arm part 4102 connected to each other, and the limiting sleeve 1211 abuts against the top wall of the movable connecting part 4101 and the top wall of the arm part 4102.

[0154] By arranging as described above, the limiting sleeve 1211 not only limits the sliding member 41, but also limits and guides the pressing part 3101 of the button 31 in the horizontal direction.

[0155] In some examples, the bottom wall at the corresponding position of the pressing part 3101 is used as the trigger part. Accordingly, the limiting sleeve 1211 is provided with a relief groove 12110 at the position corresponding to the elastic piece 510 of the micro switch 51. The relief groove 12110 is used to accommodate the elastic piece 510, so that the elastic piece 510 is as close as possible to the bottom wall of the pressing part 3101.

[0156] Furthermore, to improve the limiting effect on the slider 41, the limiting part 121 also includes a limiting rib 1212, which is connected to the side wall of the limiting sleeve 1211 and also abuts against the top wall of the movable connecting part 4101. For example, the limiting rib 1212 can be a long strip rib, the length of which is along the sliding direction of the slider 41.

[0157] In some examples, as shown in the appendix Figure 3 As shown, the call switch provided in this embodiment of the invention further includes an unlocking member 6, which can act on the sliding member 41 to make it slide, so as to release the locking connection between the first locking part 311 and the second locking part 411.

[0158] The locking connection between the first locking part 311 and the second locking part 411 can be released by the unlocking component 6. This removes the locking of both the button 31 and the slider 41, allowing the button 31 to reset under the action of the first elastic reset component 32, thus disengaging from the micro switch 51 and deactivating the call alarm. The unlocking component 6 can be used to unlock the switch via the following methods, as shown in the attached diagram. Figure 3 and combined Figure 11 As shown, the slider 41 includes a movable connecting part 4101 and an arm part 4102 connected to each other, and a second inclined wedge surface 4104 is provided at the end of the movable connecting part 4101 away from the arm part 4102.

[0159] The panel assembly 1 has a socket 14, and the unlocking end of the unlocking member 6 enters the receiving space through the socket 14 and abuts against the second inclined wedge surface 4104; the unlocking member 6 is configured such that pressing the unlocking member 6 downward can drive the sliding member 41 to slide, so that the second locking part 411 slides away from the first locking part 311.

[0160] The second wedge surface 4104 is an inclined plane, and the lower end of the second wedge surface 4104 is further away from the button 31 than its upper end.

[0161] As attached Figure 11 As shown, the unlocking end of the unlocking component 6 enters the receiving space through the insertion hole 14. When the user presses down on the unlocking component 6, the unlocking end of the unlocking component 6 drives the second inclined wedge surface 4104 of the sliding component 41, and the two slide in cooperation, thereby causing the sliding component 41 to slide (towards) Figure 11 (As shown in the right direction), thus causing the second locking part 411 to finally slide away from the first locking part 311. At this time, the top wall of the first locking part 311 is no longer blocked by the second locking part 411, so the button 31 can be reset under the elastic force of the first elastic reset member 32 to disengage from the micro switch 51 and realize alarm cancellation. At the same time, the slider 41 is reset to the initial position under the elastic force of the second elastic reset member 43.

[0162] To ensure smoother sliding contact between the unlocking end of the unlocking component 6 and the second wedge surface 4104, the unlocking end of the unlocking component 6 has an unlocking driving surface 60, which is an inclined plane or an arc-shaped surface. (The remaining text appears to be incomplete and requires further context.) Figure 11 The example shows that the unlocking drive surface 60 is a curved surface, which can achieve the effect of smoothly driving the slider 41 to slide.

[0163] For panel assembly 1 and base assembly 2, see the following embodiments: as attached Figure 2 and attached Figure 3 As shown, panel assembly 1 includes a panel 11 and a cover 12, and base assembly 2 includes a base 21 and a mounting bracket 22. The base 21 has a receiving cavity, and the cover 12 is connected to the base 21 and covers the upper port of its receiving cavity to close the cavity and form a receiving space. The mounting bracket 22 is connected to the base 21 and surrounds the outside of the base 21. The panel 11 is connected to the base 21 and covers the cover 12 and the base 21 to enhance the aesthetics of the call switch. The mounting bracket 22 is used for installing the call switch in the application environment; for example, when the call switch is installed on a wall, the mounting bracket 22 is fixedly connected to a mounting box embedded in the wall.

[0164] It should be noted that both the panel 11 and the cover 12 are provided with a button through hole 13 and a socket 14. The button through hole 13 is used to expose the pressing part 3101 of the button 31, and the socket 14 is used to allow the unlocking member 6 to be inserted into the receiving space.

[0165] Understandably, apart from some special improved designs corresponding to the embodiments of the present invention, the main structures of panel 11, cover 12, base 21 and fixing bracket 22 can be referred to the structures of corresponding components in common switches, and will not be described in detail here.

[0166] Based on the structure of the call switch provided in the embodiments of the present invention, the assembly method of the call switch is described below as an example:

[0167] The functional component 5 is placed inside the base 21. For example, the circuit board 52 of the functional component 5 is placed inside the base 21, and a support member 42 is placed on the circuit board 52 and fixed and locked with screws. The second elastic reset member 43 is assembled into the slider 41. For example, the second elastic reset member 43 passes through the second limiting cavity 4103 of the movable connecting portion 4101 of the slider 41 and is connected, and then the whole is movably connected to the support member 42. Then, the lower end of the first elastic reset member 32 is connected to the connecting sleeve 212 on the base 21.

[0168] The button 31 is assembled into the base 21, making the two movably connected. The first wedge surface 3111 of the first locking portion 311 on the button 31 abuts against the second locking portion 411 of the slider 41. Then, the cover 12 is fastened to the top of the base 21, and the cover 12 is correspondingly fitted with the movable connection portion 4101 of the button 31 and the slider 41. Finally, the base 21 is assembled with the mounting bracket 22, and the panel 11 is assembled with the mounting bracket 22, thus completing the assembly of the call switch.

[0169] In summary, the call switch provided in this embodiment of the invention discloses a novel locking structure. Locking and unlocking operations are achieved by sliding the first locking part 311 on the button 31 in conjunction with the second locking part 411 on the slider 41. Compared to the locking method where a metal spring is fixed to the side wall of the button, this effectively avoids the problems of button 31 failing to lock or unlock. Furthermore, the unlocking member 6 uses a push-press method for unlocking, which is more effortless, more in line with user habits, and improves the user experience.

[0170] The call switch provided in this embodiment of the invention has fewer parts, each part has a simple structure and is easy to mold and manufacture, and the compact assembly between the parts is convenient, which helps to improve the yield of call switch products.

[0171] In embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0172] The above description is merely for the purpose of enabling those skilled in the art to understand the technical solutions of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
