Description

Technical Field

[0001] This utility model belongs to the field of product waterproof structure technology, specifically relating to a structure for improving the waterproof performance of products. Background Technology

[0002] Currently, the waterproofing structure used for buttons both domestically and internationally is basically achieved by waterproof rings. However, ordinary waterproof ring structures cannot simultaneously meet the requirements of stability, durability, comprehensive waterproofing, and optimized button feel.

[0003] like Figure 1 As shown, in the prior art, a protruding sealing part 7 is provided on the inner ring of the waterproof cover. The gun holder button is formed on the waterproof cover through a vulcanization and rubber coating process. A non-detachable sealing groove is formed on the gun holder button to mate with the sealing part. A waterproof structure is formed between the non-detachable sealing groove and the sealing part.

[0004] The waterproof structure formed between the aforementioned waterproof cap and the gun holder button is susceptible to loosening and detachment under manual pressing of the button (soft rubber). This is due to the lack of tightness around the button, and frequent pressing can severely compromise the product's waterproof performance, hindering stable and reliable production. Furthermore, the limited contact area during the vulcanization process of the button and waterproof cap can lead to insufficient rubber coverage and difficulties in filling the rubber layer, further increasing costs associated with high defect rates. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a structure for improving the waterproof performance of products, thereby solving the technical problem that the waterproof structure on the existing gun holder button is prone to loosening and falling off after frequent pressing, leading to the failure of the waterproof structure.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0007] A structure for improving the waterproof performance of a product includes a waterproof cover, a button body, a connecting rod, and a hook. The button body is mounted on the waterproof cover. The hook is rotatably connected to the corresponding product at its center and is connected to the button body via the connecting rod.

[0008] The waterproof cover is equipped with a sealing element. The button body has an annular groove that mates with the sealing element. The sealing element fits against the surface of the groove. A downwardly extending limiting part is provided on the outer edge of the groove. The limiting part and the groove cooperate to form a waterproof structure that covers the sealing element.

[0009] Furthermore, the top edge of the seal is provided with multiple anti-detachment grooves.

[0010] Furthermore, each of the anti-detachment grooves is circumferentially distributed around the axis of the retaining wall, forming a concave-convex retaining wall structure at the top edge of the seal.

[0011] Furthermore, the bottom of the button body is provided with a stepped surface. The stepped surface, in conjunction with the sealing element, defines the position of the button body.

[0012] Furthermore, the hook has a spring at its tail end. The top of the spring abuts against the waterproof cap.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model incorporates a sealing element on a waterproof cover. The button body has an annular groove that mates with the sealing element. The sealing element adheres to the surface of the groove. A downwardly extending limiting portion is provided on the outer edge of the groove, forming a waterproof structure that covers the sealing element. This increases the contact area between the button body and the sealing element, preventing the button body from detaching while improving waterproof performance.

[0015] 2. This new invention adds a concave-convex retaining wall structure to the top edge of the sealing element. The concave-convex retaining wall structure increases the contact area with the button body during molding, which can enhance the clamping force between the soft and hard rubber while simplifying the processing. It effectively prevents the button body from detaching during use and greatly improves the waterproof performance of the product. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 2 and 3 As shown, a structure for improving the waterproof performance of a product includes a waterproof cover 1, a button body 2, a connecting rod, and a hook. The button body 2 is mounted on the waterproof cover 1. The hook is rotatably connected to the corresponding product at its center and is connected to the button body 2 via the connecting rod. When a worker presses the button body 2, the force applied to the button body 2 is transmitted to the internal components of the product through the connecting rod and the hook, executing the corresponding command.

[0024] like Figure 3 As shown, the waterproof cover 1 is equipped with a sealing element 3. The button body 2 has an annular groove that mates with the sealing element 3. The sealing element 3 fits against the surface of the groove. A downwardly extending limiting part 4 is provided on the outer edge of the groove. The limiting part 4 and the groove cooperate to form a waterproof structure that covers the sealing element 3. The waterproof structure increases the contact area between the button body 2 and the sealing element 3, effectively reducing the risk of the button body 2 falling off during manual pressing and preventing liquid from entering the device and causing damage.

[0025] Furthermore, such as Figure 2 As shown, the top edge of the seal 3 has multiple anti-detachment grooves 5. Each anti-detachment groove 5 is evenly distributed circumferentially around the axis of the retaining wall portion, thus forming a concave-convex retaining wall structure at the top edge of the seal 3. This concave-convex retaining wall structure increases the contact area with the button body 2 during molding, effectively preventing the button body 2 from detaching.

[0026] In this embodiment, as Figure 4 As shown, the button body 2 is formed around the seal 3 by vulcanization and rubber coating. Furthermore, the bottom of the button body 2 has an integrally formed snap-fit ​​portion 6. The outer dimension of the snap-fit ​​portion 6 is larger than the dimension of the part where the button body 2 contacts it, thus forming a stepped surface that matches the bottom of the seal 3. The button body 2 is fixed to the waterproof cover 1 through the fit between the snap-fit ​​portion 6 and the seal 3, further preventing the button body 2 from detaching during use.

[0027] In this embodiment, a spring is provided at the tail end of the hook. The top of the spring abuts against the waterproof cover 1. When the operator releases the force applied to the button body 2, the spring returns to its original position, thereby causing the hook and the button body 2 to reset.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
