It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. Membrane switch has the characteristics of reliability, long life, dustproof, waterproof, and corrosion resistance, and is widely used in various industries.

[0003] In the prior art, some membrane switches are also equipped with a protective assembly. For example, the patent with publication number CN218782959U discloses a membrane switch protective assembly, which can provide a good protective effect on the membrane switch body by setting a protective cover that can be flipped upward 180 degrees. However, in the actual application of the membrane switch with the above-mentioned membrane switch protective assembly, since the opening of the protective cover requires sufficient space, the membrane switch cannot be installed in a too narrow space, which will limit the application scope of the membrane switch. Therefore, the utility model proposes a membrane switch protective assembly that can be applied to narrow spaces. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example: See Figures 1 to 7According to an embodiment of the utility model, a technical solution is provided: a membrane switch protection component, comprising an upper protective shell 1 and a lower protective shell 2 slidably connected by a sliding connection, a membrane switch body 3 is installed between the upper protective shell 1 and the lower protective shell 2, in this embodiment, a mounting groove 18 for accommodating the membrane switch body 3 is opened on a side of the lower protective shell 2 facing the upper protective shell 1, and the membrane switch body 3 is embedded and installed in the mounting groove 18, the sliding connection comprises a first sliding hole 5 arranged along the length direction of the left and right sides of the lower protective shell 2 and a first slider 4 arranged on the left and right sides of the upper protective shell 1, the first slider 4 is embedded in the first sliding hole 5 and can slide along the length direction of the first sliding hole 5 and in a direction perpendicular to the lower protective shell 2, the sliding connection also includes a support bar 6, a spring 7 and a ball 8, the spring 7 is arranged between the support bar 6 and the upper protective shell 1, and the ball 8 is rotatably arranged at the bottom of the support bar 6 and against the lower protective shell 2.

[0031] With the membrane switch protection assembly of the above structure, the upper protective shell 1 and the lower protective shell 2 can protect the membrane switch body 3, and the membrane switch body 3 can be covered or exposed by pressing the upper protective shell 1 toward the lower protective shell 2 and sliding the upper protective shell 1 in a direction parallel to the lower protective shell 2. Since the upper protective shell 1 is arranged to open by sliding, this opening method can be completed in a narrow space. Therefore, the membrane switch with the membrane switch protection assembly can be installed in a narrow space for use.

[0032] In this embodiment, grooves 9 are provided on both sides of the lower protective shell 2, and n-shaped connecting edges 10 are provided on both sides of the upper protective shell 1. The first slider 4 is provided on the side of the connecting edge 10 away from the upper protective shell 1, and the support bar 6, spring 7 and ball bearing 8 are all provided on the inner side of the connecting edge 10. By providing the groove 9, the sliding direction of the connecting edge 10 can be limited, thereby ensuring that the upper protective shell 1 slides along a predetermined track.

[0033] In this embodiment, second sliders 11 are formed protrudingly on both sides of the top of the support bar 6, and second sliding holes 12 are opened on both sides of the connecting edge 10. The second sliders 11 are embedded in the second sliding holes 12 and can slide in a direction perpendicular to the lower protective shell 2. By providing the second sliders 11 and the second sliding holes 12, a sliding connection can be formed between the support bar 6 and the connecting edge 10 in a direction perpendicular to the lower protective shell 2. Of course, as long as a sliding connection can be formed between the support bar 6 and the connecting edge 10 in a direction perpendicular to the lower protective shell 2, there is no special restriction on the specific connection method between the support bar 6 and the connecting edge 10.

[0034] In this embodiment, a first limiting groove 13 is formed at the top of the connecting edge 10, a second limiting groove 14 is formed at the inner top of the connecting edge 10, and the spring 7 is installed between the first limiting groove 13 and the second limiting groove 14. The position of the spring 7 can be limited by the first limiting groove 13 and the second limiting groove 14, so that the spring 7 is in the correct position.

[0035] In this embodiment, the end of the support bar 6 away from the first slider 4 is provided with a protruding connection edge 10 and is rotatably connected with a roller 15, and the bottom surface of the roller 15 is flush with the bottom of the lower protective shell 2. Through the arrangement of the roller 15, when the upper protective shell 1 is opened, the roller 15 rolls on the wall and provides support for the upper protective shell 1, thereby improving the sliding stability of the upper protective shell 1.

[0036] In this embodiment, a first anti-slip pattern 16 is provided on the top of the first slider 4, and a second anti-slip pattern 17 is provided on the top of the first slide hole 5 along the length direction. By providing the first anti-slip pattern 16 and the second anti-slip pattern 17, when the upper protective shell 1 is opened and the user releases the upper protective shell 1, the first slider 4 will abut against the inner top of the first slide hole 5. At this time, the first anti-slip pattern 16 and the second anti-slip pattern 17 can increase the friction between the first slider 4 and the lower protective shell 2, so that the upper protective shell 1 is kept in the open position.

[0037] In this embodiment, a window 19 is provided at the middle of the top of the upper protective shell 1 corresponding to the position of the membrane switch body 3, and a transparent plate 20 is installed in the window 19. The provision of the transparent plate 20 can facilitate users to observe the membrane switch body 3 so as to obtain information on the panel of the membrane switch.

[0038] Working principle: When in use, the user first fixes the bottom of the lower protective shell 2 on the wall where the membrane switch needs to be installed with screws or tape. When the membrane switch is not in use, the upper protective shell 1 is closed to cover the membrane switch body 3. At this time, the upper protective shell 1 and the lower protective shell 2 can form a protection for the membrane switch body 3. When the membrane switch needs to be used, the upper protective shell 1 can be pressed toward the lower protective shell 2 while sliding the upper protective shell 1 in a direction parallel to the lower protective shell 2 to expose the membrane switch body 3. At this time, the user can operate the membrane switch body 3.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
