The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] refer to Figure 1In one embodiment, a doorbell installation device 10 is provided, which includes a thimble 100 and a doorbell structure 200. The doorbell structure 200 is generally installed on a door or a wall to remind the user that there is a visitor. The thimble 100 can disassemble the doorbell structure 200. The doorbell structure 200 includes a doorbell assembly 300 and a base 400. The doorbell assembly 300 and the base 400 are detachable structures and can be realized by the thimble 100. The doorbell structure 200 has a simple structure and is easy for users to assemble or disassemble.

[0027] refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In one embodiment, the base 400 includes a bottom plate 410 and a spring 420. The user can first fix the bottom plate 410 on a wall or a door. The fixing method can be adhesive, screws, pins, etc. The bottom plate 410 is provided with a receiving groove 411. The receiving groove 411 runs through two opposite sides of the bottom plate 410. The spring 420 is received in the receiving groove 411, and one end of the spring 420 is connected to the groove wall of the receiving groove 411, and the other end is spaced from the groove wall of the receiving groove 411. Specifically, the receiving groove 411 is roughly a square groove. The spring 420 is an element with a certain elasticity. One end of the spring 420 is fixedly connected to the groove wall of the receiving groove 411, and the other end is received in the receiving groove 411. When an external force acts on the spring 420, the spring 420 can be elastically deformed so that the spring 420 moves from the first position to the second position. In one embodiment, the spring piece 420 has a first inclined surface 421, and the bottom plate 410 is further provided with a through hole 412, which can be connected to the receiving groove 411, and the axis extension line of the through hole 412 can pass through the first inclined surface 421, so that the ejector pin 100 can pass through the through hole 412 and slide along the first inclined surface 421.

[0028] refer to Figure 2 , Figure 3 and Figure 5In one embodiment, the doorbell assembly 300 is provided with a limiting groove 310 on one side facing the bottom plate 410. When the doorbell assembly 300 is mounted on the bottom plate 410, a part of the structure of the spring 420 can be held in the limiting groove 310. At this time, the doorbell assembly 300 and the bottom plate 410 are relatively stationary and fixed, that is, the assembly of the doorbell assembly 300 and the bottom plate 410 is completed. Specifically, when the user needs to remove the doorbell assembly 300 from the bottom plate 410, the user can pick up the ejector pin 100, so that the ejector pin 100 passes through the through hole 412 and slides along the first inclined surface 421, and slides between the doorbell assembly 300 and the spring 420. The spring 420 is deformed due to the extrusion of the ejector pin 100, so that the spring 420 moves from the first position to the second position, that is, at this time, a part of the structure of the spring 420 is separated from the limiting groove 310, thereby realizing the separation of the doorbell assembly 300 from the base 400. It can be understood that the angle between the first bevel 421 and the base 400 is 20 degrees to 40 degrees, and the more optimized angle between the first bevel 421 and the base 400 is about 30 degrees. The first bevel 421 at this angle can help the ejector pin 100 to slide more smoothly on the first bevel 421, which is more conducive to the ejector pin 100 sliding from the first bevel 421 to between the doorbell assembly 300 and the spring 420, and helps part of the structure of the spring 420 to detach from the limiting groove 310.

[0029] refer to Figure 4 and Figure 5 In one embodiment, the spring piece 420 includes a connecting portion 422 and an acting portion 423 connected to the connecting portion 422, the connecting portion 422 is connected to the groove wall of the accommodating groove 411, the acting portion 423 is spaced from the groove wall of the accommodating groove 411, the acting portion 423 is provided with a slide groove 424, and the first inclined surface 421 is located at the groove bottom of the slide groove 424. Figure 2Specifically, the slide groove 424 is generally a C-shaped groove, and the slide groove 424 has a first opening and a second opening opposite to each other. The ejector pin 100 can enter the first opening of the slide groove 424, pass through the first inclined surface 421 and slide out from the second opening opposite to each other to the surface of the connecting portion 422, so that the ejector pin 100 is located between the spring piece 420 and the doorbell assembly 300. It can be understood that when the ejector pin 100 slides on the first inclined surface 421, that is, when the ejector pin 100 slides on the bottom of the slide groove 424, the groove wall of the slide groove 424 has a guiding effect on the sliding of the ejector pin 100, which can prevent the sliding route of the ejector pin 100 from being unclear and deviating. In one embodiment, a protrusion 425 is provided on the side of the action portion 423 facing the doorbell assembly 300, and the protrusion 425 protrudes from the bottom plate 410. The shape of the protrusion 425 is mutually adapted to the limiting groove 310, so that the protrusion 425 can be clamped in the limiting groove 310. When the ejector pin 100 passes through the through hole 412 and the first inclined surface 421 and slides between the doorbell assembly 300 and the spring sheet 420, the spring sheet 420 is deformed, and the spring sheet 420 moves from the first position to the second position, that is, the protrusion 425 is converted from the state of being clamped in the limiting groove 310 to the state of being separated from the limiting groove 310, so that the doorbell assembly 300 is separated from the bottom plate 410. Specifically, the height of the ejector pin 100 is greater than or equal to the height of the protrusion 425, and the height of the protrusion 425 can be the height of the protrusion 425 accommodated in the limiting groove 310. When the ejector pin 100 is located between the doorbell assembly 300 and the spring sheet 420, due to the height setting of the ejector pin 100, the protrusion 425 can be completely withdrawn from the limiting groove 310, effectively preventing the partial structure of the protrusion 425 from being accommodated in the limiting groove 310, resulting in obstacles to the separation of the doorbell assembly 300 and the bottom plate 410.

[0030] In one embodiment, the width of the connection portion 422 may be different from the width of the action portion 423 and may be adjusted according to the needs of the user, that is, the width of the connection portion 422 may be less than or equal to the width of the action portion 423. Specifically, when the user wishes to assemble the doorbell assembly 300 and the base 400 more flexibly, the width of the connection portion 422 may be set to be less than the width of the action portion 423, so that when the user applies the ejector pin 100 to the first inclined surface 421 on the action portion 423, the arc of deformation of the connection portion 422 is larger, and the user does not need to apply a large pressure to the ejector pin 100, and the spring sheet 420 can be deformed and then moved from the first position to the second position and separated from the limiting groove 310, and the cooperation between the ejector pin 100 and the spring sheet 420 is more sensitive. When the user hopes that the anti-disassembly performance of the assembly of the doorbell assembly 300 and the base 400 will be higher, the connecting portion 422 can be set to be equal to or slightly larger than the width of the action portion 423, so that when the user applies the ejector pin 100 to the first inclined surface 421 on the action portion 423, the connecting portion 422 is not easily deformed. Then the user needs to apply greater pressure to the ejector pin 100 so that the spring piece 420 can be deformed and separated from the limiting groove 310, thereby making the assembly of the doorbell assembly 300 and the base 400 more secure.

[0031] refer to Figure 2 and Figure 4 In one embodiment, the bottom plate 410 is provided with a slot 413, and the doorbell assembly 300 is provided with a hook 320 on the side facing the bottom plate 410, and the hook 320 can be clamped in the slot 413. The mutual clamping action between the hook 320 and the slot 413 can further make the assembly between the doorbell assembly 300 and the bottom plate 410 more stable, which is conducive to the doorbell assembly 300 not being easily separated from the bottom plate 410. Figure 6In one embodiment, the slot 413 includes a first holding slot 4131 and a second holding slot 4132, the first holding slot 4131 and the second holding slot 4132 are connected to each other, and the maximum width of the first holding slot 4131 is greater than the maximum width of the second holding slot 4132. Further, the first holding slot 4131 can be through both sides of the bottom plate 410, and the maximum width of the first holding slot 4131 should be greater than the maximum width of the hook 320, so that the hook 320 can pass through the first holding slot 4131. After the hook 320 passes through the first holding slot 4131, the doorbell assembly 300 can slide in the reverse direction. At this time, the hook 320 is held in the second holding slot 4132. When the hook 320 is held, the protrusion 425 of the spring 420 is also held in the limiting slot 310. Due to the joint holding of the hook 320 and the protrusion 425, the doorbell assembly 300 can be more firmly installed on the bottom plate 410. Specifically, when the hook 320 is retained in the second retaining groove 4132, the doorbell assembly 300 is not limited, that is, the doorbell assembly 300 may still slide, and the hook 320 may be disengaged from the second retaining groove 4132. At this time, the protrusion 425 is retained in the limiting groove 310, which effectively limits the position between the doorbell assembly 300 and the bottom plate 410, thereby preventing the doorbell assembly 300 from separating from the bottom plate 410, making the assembly of the doorbell assembly 300 and the bottom plate 410 more stable.

[0032] refer to Figure 5 In one embodiment, the protrusion 425 has a supporting surface 4251, a transition surface 4252 and a second inclined surface 4253, and the transition surface 4252 is located between the supporting surface 4251 and the second inclined surface 4253. Figure 2 During the assembly of the doorbell assembly 300 with the base 400, first align the hook 320 of the doorbell assembly 300 with the first holding groove 4131 to insert the hook 320 into the first holding groove 4131. At this time, the spring piece 420 is pressed against the doorbell assembly 300 and deformed. The user continues to slide the doorbell assembly 300 in the opposite direction to move the hook 320 to be held in the second holding groove 4132. The spring piece 420 moves to the position of the limit groove 310, that is, moves to the first position to be held in the limit groove 310. It can be understood that when the spring piece 420 is in the process of resisting the doorbell assembly 300 and being stuck in the limiting groove 310, the spring piece 420 first resists the doorbell assembly 300 and deforms, and the doorbell assembly 300 continues to move to slide along the second inclined surface 4253, and slides from the second inclined surface 4253 through the transition surface 4252, and finally moves to the relative position between the limiting groove 310 and the protrusion 425 of the spring piece 420, at which time the spring piece 420 recovers its deformation and is located in the first position, and then the protrusion 425 is stuck in the limiting groove 310.

[0033] It is understandable that when the user wishes to separate the doorbell assembly 300 from the base 400, the user can first slide the ejector pin 100 through the through hole 412 and along the first inclined surface 421 to between the doorbell assembly 300 and the base 400. At this time, the protrusion 425 of the spring 420 is separated from the limiting groove 310, and then the user can push the doorbell assembly 300 with his hand to push the doorbell assembly 300 in the forward direction (forward and reverse are opposite directions). At this time, the hook 320 can move from the position held in the second holding groove 4132 to the position accommodated in the first holding groove 4131. The user then picks up the doorbell assembly 300 from the base 400, thereby achieving the separation of the doorbell assembly 300 from the base 400.

[0034] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
