Description

Technical Field

[0001] This utility model relates to the field of waterproof switches, specifically a waterproof switch that prevents the push handle from breaking. Background Technology

[0002] A waterproof switch is a type of switch with good waterproof properties, allowing the handle to be pressed with wet hands, thus increasing electrical safety.

[0003] Existing waterproof switches, such as the waterproof push button switch proposed in patent application number "CN201921133898.4", include a housing, a button, a moving contact, and a first stationary contact and a second stationary contact. The housing includes a cavity, one end of the button is slidably disposed in the cavity, and the other end of the button extends outward from the housing. A slider is disposed at the end of the button disposed in the cavity. The side wall of the cavity is provided with a groove that mates with the slider. The slider is provided with a groove for embedding the moving contact. The groove includes a bottom inner wall and two opposing insertion slots. The moving contact includes a fixing part for inserting into the bottom inner wall of the groove. The fixing part extends outward along the two insertion slots and bends to form clamping feet for respectively holding the first stationary contact and the second stationary contact. This utility model provides a waterproof push button switch in which the moving contact is less prone to deformation under button pressing, thus reducing the risk of poor contact.

[0004] However, existing technologies have drawbacks. When using a push-button control switch, pressing the push-button can cause excessive pressure and large swing amplitude in some high-push-button waterproof switches, which can easily lead to breakage and damage to the switch. Therefore, a waterproof switch that prevents push-button breakage is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof switch that prevents the push handle from breaking, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A waterproof switch to prevent the handle from breaking includes a base and a cover plate. The cover plate is bolted to the upper end of the base. An inner cavity is formed between the cover plate and the base. A vertical cylinder is fixed to the upper end of the cover plate. A handle is inserted into the vertical cylinder. The handle passes through the cover plate and is inserted into the inner cavity.

[0008] The inner cavity is fitted with a silicone pad, a waterproof membrane, an inner button, and a spring. The button is pressed against the silicone pad. The waterproof membrane is located between the silicone pad and the inner button. The inner button is pressed against the spring. Two sets of clips are fitted on the base. One set of clips is fixed with a guide component one, and the other set of clips is fixed with a guide component two. The middle of the spring is pressed against the guide component one, and the edge of the spring is abutted against the guide component two.

[0009] Preferably, the vertical cylinder sidewall is fixed with multiple sets of reinforcing ribs, the lower ends of which are fixed to the upper end of the cover plate. The multiple sets of reinforcing ribs are arranged in a circumferential array, and the shape of each set of reinforcing ribs is set as a right triangle.

[0010] Preferably, a ring is fixed to the lower end of the cover plate, the ring is pressed against the upper end of the silicone pad, and a groove is provided at the upper end of the base, in which the silicone pad is snapped into the groove.

[0011] Preferably, the inner wall of the cavity has multiple sets of slots, each set of slots has an elastic support foot fixedly connected to it, the end of the elastic support foot is fixedly connected to a clamping plate, the clamping plate slides on the bottom wall of the inner cavity, the clamping plate is set to be arc-shaped, and the clamping plate is pressed and engaged with the side wall of the spring piece.

[0012] Preferably, a pressing seat is fixedly connected to the lower end of the handle, the inner cavity diameter is larger than the diameter of the central hole of the vertical cylinder, the pressing seat slides in the inner cavity, and a pressing end for squeezing the middle of the silicone pad is fixedly connected to the lower end of the pressing seat.

[0013] Preferably, the spring sheet is slightly arched, with protrusions fixed to both the upper and lower ends of the inner side. The protrusion at the upper end is pressed and engaged with the center of the bottom of the silicone pad, and the protrusion at the lower end is pressed and engaged with the center of the spring sheet.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes a mechanism where pressing the handle compresses a silicone pad, which in turn compresses a waterproof membrane, which in turn compresses an inner button, which in turn compresses a spring. This causes the center of the spring to contact the conductor, enabling conductivity between the two sets of clips. The silicone pad and waterproof membrane enhance the switch's waterproof performance. However, adding these components makes controlling the pressing direction more difficult. By adding an inner button to the spring, the pressing direction becomes more consistent, providing a better tactile feedback. A vertical cylinder is installed on the cover plate, and its upward extension lengthens the support path for the handle, increasing its protection and preventing breakage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A waterproof switch to prevent the push handle from breaking, such as Figures 1-6 As shown, it includes a base 1 and a cover plate 3. The cover plate 3 is fixed to the upper end of the base 1 by bolts 19. An inner cavity 21 is opened between the cover plate 3 and the base 1. A vertical cylinder 4 is fixed to the upper end of the cover plate 3. A handle 6 is inserted into the vertical cylinder 4. The handle 6 passes through the cover plate 3 and is inserted into the inner cavity 21.

[0027] The inner cavity 21 is fitted with a silicone pad 8, a waterproof membrane 10, an inner button 11, and a spring piece 12. The handle 6 is pressed against the silicone pad 8. The waterproof membrane 10 is located between the silicone pad 8 and the inner button 11. The inner button 11 is pressed against the spring piece 12. Two sets of clips 13 are fitted onto the base 1. One set of clips 13 is fixedly connected to a guide 14, and the other set of clips 13 is fixedly connected to a guide 2 15. The middle of the spring piece 12 is pressed against the guide 14, and the edge of the spring piece 12 abuts against the guide 2 15.

[0028] By pressing the handle 6, the lower end of the handle 6 squeezes the silicone pad 8, the silicone pad 8 squeezes the waterproof membrane 10, the waterproof membrane 10 squeezes the inner button 11, and the inner button 11 squeezes the spring piece 12, so that the middle part of the spring piece 12 contacts the conductor 14 to conduct electricity, so that the two sets of clips 13 conduct electricity through the spring piece 12. The silicone pad 8 and the waterproof membrane 10 increase the waterproof performance of the switch. After adding the silicone pad 8 and the waterproof membrane 10 to the switch, it is more difficult to control the pressing direction. Adding an inner button 11 on the spring piece 12 makes the pressing direction of the spring piece 12 more consistent and provides customers with a better pressing feel. A vertical cylinder 4 is set on the cover plate 3. The vertical cylinder 4 is stretched upward, so that the support path of the vertical cylinder 4 for the handle 6 is longer, which increases the protection of the handle 6 and prevents the handle 6 from breaking.

[0029] like Figure 1 As shown, the vertical cylinder 4 has multiple sets of reinforcing ribs 5 fixedly connected to its side wall. The lower ends of the multiple sets of reinforcing ribs 5 are all fixedly connected to the upper end of the cover plate 3. The multiple sets of reinforcing ribs 5 are arranged in a circumferential array, and the shape of the multiple sets of reinforcing ribs 5 is set as right-angled triangles.

[0030] A reinforcing rib 5 is fixed between the vertical cylinder 4 and the cover plate 3 to increase the structural stability of the vertical cylinder 4.

[0031] like Figure 3 As shown, a ring 20 is fixed to the lower end of the cover plate 3. The ring 20 is pressed against the upper end of the silicone pad 8. A groove 2 is provided at the upper end of the base 1, and the silicone pad 8 is snapped into the groove 2.

[0032] After the cover plate 3 and the base 1 are fixed together by bolts 19, the silicone pad 8 is snapped between the cover plate 3 and the base 1, and the ring 20 presses the silicone pad 8 to seal the cover plate 3 and the base 1.

[0033] like Figure 4 and Figure 5 As shown, the inner wall of the inner cavity 21 has multiple sets of slots 16, and each set of slots 16 is fixedly connected to an elastic support leg 17. The end of the elastic support leg 17 is fixedly connected to a clamping plate 18. The clamping plate 18 slides on the bottom wall of the inner cavity 21. The clamping plate 18 is arc-shaped and is pressed against the side wall of the spring piece 12.

[0034] As the spring piece 12 is squeezed by the inner press 11, the spring piece 12 deforms, and there is a certain gap between the edge of the spring piece 12 and the side wall of the inner cavity 21. When installing the spring piece 12, the spring piece 12 is installed downwards and installed between multiple sets of clamping plates 18. The clamping plates 18 are squeezed, causing the elastic support leg 17 to compress and deform, and squeezing the clamping plates 18 in the opposite direction, so that the arc-shaped clamping plates 18 squeeze the side wall of the spring piece 12, so that the spring piece 12 is centered inside the inner cavity 21, and the middle part of the spring piece 12 is aligned with the middle part of the inner press 11, increasing the accuracy and feel of the button 6.

[0035] like Figure 2 and Figure 3As shown, a pressing seat 7 is fixedly connected to the lower end of the handle 6. The diameter of the inner cavity 21 is larger than the diameter of the central hole of the vertical cylinder 4. The pressing seat 7 slides in the inner cavity 21. A pressing end for squeezing the middle of the silicone pad 8 is fixedly connected to the lower end of the pressing seat 7.

[0036] The pressing end is pressed against the center of the silicone pad 8, and the pressing seat 7 will not detach from the inner cavity 21.

[0037] like Figure 2 and Figure 3 As shown, the spring piece 12 is slightly arched, and protrusions are fixed to the upper and lower ends of the inner pad 11. The protrusion at the upper end is pressed and engaged with the center position of the bottom of the silicone pad 8, and the protrusion at the lower end is pressed and engaged with the center position of the spring piece 12.

[0038] The protrusions and the spring sheet 12 are used to squeeze the material, resulting in a moderate pressing force and a better pressing feel.

[0039] The working principle of the waterproof switch that prevents the handle 6 from breaking, provided by this utility model, is as follows:

[0040] By pressing the handle 6, the lower end of the handle 6 squeezes the silicone pad 8, the silicone pad 8 squeezes the waterproof membrane 10, the waterproof membrane 10 squeezes the inner button 11, and the inner button 11 squeezes the spring piece 12, so that the middle part of the spring piece 12 contacts the conductor 14 to conduct electricity, so that the two sets of clips 13 conduct electricity through the spring piece 12. The silicone pad 8 and the waterproof membrane 10 increase the waterproof performance of the switch. After adding the silicone pad 8 and the waterproof membrane 10 to the switch, it is more difficult to control the pressing direction. Adding an inner button 11 on the spring piece 12 makes the pressing direction of the spring piece 12 more consistent and provides customers with a better pressing feel. A vertical cylinder 4 is set on the cover plate 3. The vertical cylinder 4 is stretched upward, so that the support path of the vertical cylinder 4 for the handle 6 is longer, which increases the protection of the handle 6 and prevents the handle 6 from breaking.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
