[0037] During actual use of medical devices, due to the disinfection requirements of the devices, they need to be wiped and disinfected frequently with disinfectants. The keys on the key panel of the medical device need to rebound after being pressed. Therefore, in order to ensure the normal rebound of the keys, it is necessary to reserve sufficient gaps between the keys and the outer casing. In order to ensure waterproofing, it is generally necessary to add waterproof parts inside. After long-term use, the waterproof parts are prone to loosening and other problems, resulting in waterproof failure. The disinfectant flows into the medical device through the keys, causing a short circuit inside the medical device, resulting in economic losses.

[0038] In view of this, the utility model proposes a waterproof key panel, in which during each key operation, the pressing operation can only cause the corresponding part of the pressing portion on the protrusion to be concave and deformed, while the peripheral side surface of the protrusion and the wall surface of the corresponding key hole are relatively static, so as to play a waterproof role without setting up an additional waterproof structure, thereby solving the problem that the key panel is prone to waterproof failure after long-term use. Figures 1 to 5 FIG. 1 is an example of a novel waterproof key panel.

[0039] like Figures 1 to 3 As shown, the waterproof key panel 100 proposed by the utility model includes an operation panel 1, a soft colloid 2 and a key assembly 3. The operation panel 1 has a receiving groove 11 with an opening facing downward, and a plurality of key holes 11a are arranged on the bottom wall of the receiving groove 11; the soft colloid 2 is arranged in the receiving groove 11, and a plurality of grooves 21 are concavely arranged on the lower side of the soft colloid 2, and each of the grooves 21 forms a protrusion on the upper side of the soft colloid 2, and the protrusion passes through the corresponding key hole 11a, and its upper end surface is exposed outside the receiving groove 11 to form a pressing portion 22, and the key hole 11a is formed on the upper side of the soft colloid 2. An elastic abutment 23 is provided on the lower end face of the pressing portion 22, and the peripheral side face of the protrusion contacts the wall surface of the button hole 11a; the button assembly 3 includes a mounting plate 31 and a plurality of buttons 32, the mounting plate 31 is arranged in the accommodating groove 11 and is located below the soft gel 2, and the plurality of buttons 32 are arranged on the upper end face of the mounting plate 31 and are respectively arranged corresponding to the plurality of grooves 21; wherein the pressing portion 22 is used to be recessed under the action of external force so that the corresponding elastic abutment 23 can move downward to press the corresponding button 32.

[0040] In the technical solution of the utility model, the waterproof key panel 100 includes an operation panel 1, a soft colloid 2 and a key assembly 3, wherein the operation panel 1 has a receiving groove 11 with an opening facing downward, and a plurality of key holes 11a are arranged on the bottom wall of the receiving groove 11; the soft colloid 2 is arranged in the receiving groove 11, and a plurality of grooves 21 are concavely arranged on the lower side of the soft colloid 2, and each of the grooves 21 forms a protrusion on the upper side of the soft colloid 2, and the protrusion passes through the corresponding key hole 11a, and its upper end surface is exposed outside the receiving groove 11 to form a pressing portion 22, and the key hole 11a is formed on the upper side of the soft colloid 2. The lower end surface of the pressing portion 22 is provided with an elastic abutting portion 23, and the peripheral side surface of the protrusion contacts the wall surface of the key hole 11a; the key assembly 3 includes a mounting plate 31 and a plurality of keys 32, the mounting plate 31 is arranged in the accommodating groove 11 and is located below the soft colloid 2, and the plurality of keys 32 are arranged on the upper end surface of the mounting plate 31 and are respectively arranged corresponding to the plurality of grooves 21; wherein the pressing portion 22 is used to be concave under the action of an external force, so that the corresponding elastic abutting portion 23 can move downward to press the corresponding key 32. In this way, during the operation of each key 32, the pressing operation can only cause the corresponding part of the pressing portion 22 on the protrusion to be concave and deformed, while the peripheral side surface of the protrusion and the corresponding wall surface of the key hole 11a are relatively static, so as to play a waterproof role without the need to set up an additional waterproof structure, thereby solving the problem that the key 32 panel is prone to waterproof failure after long-term use.

[0041] In this embodiment, the peripheral side surface of the protrusion is interference-fitted with the wall surface of the corresponding key hole 11a, so that the peripheral side surface of the protrusion and the wall surface of the corresponding key hole 11a are more closely matched, thereby improving the waterproof performance of the waterproof key panel 100.

[0042] In this embodiment, if Figure 3 As shown, the lower end surface of the soft colloid 2 abuts against the upper end surface of the mounting plate 31. The mounting plate 31 supports the soft colloid 2, so that, combined with the interference fit between the protrusion and the corresponding key hole 11a, it is ensured that after the waterproof key panel 100 is used for a long time, the soft colloid 2 and the operation panel 1 will not move relative to each other, thereby ensuring the waterproof performance of the waterproof key panel 100.

During the operation of each of the keys 32, the corresponding part of the pressing portion 22 on the protrusion is deformed by pressing operation, so that the elastic abutment portion 23 can move downward to press the corresponding key 32, wherein the elastic abutment portion 23 will elastically deform when pressing the key 32, and when the external force is removed, the elastic abutment portion 23 will restore the deformation and restore the pressing portion 22 to its original state. Through the structural design of the connecting column 231, the connecting column 231 and the pressing portion 22 have a larger contact area, so that the force generated by the elastic abutment portion 23 restoring the deformation can be better utilized, so that the pressing portion 22 can quickly restore its original state.

[0044] In this embodiment, if Figure 2 and Figure 4 As shown, the circumferential side of the soft colloid 2 is concavely provided with a limiting groove 24, and the wall surface of the limiting groove 24 passes through the upper and lower end surfaces of the soft colloid 2; the bottom wall of the accommodating groove 11 is provided with a limiting column 11b, and the limiting column 11b cooperates with the limiting groove 24 to limit the installation of the soft colloid 2. In this way, the combination of the limiting column 11b and the limiting groove 24 can realize the installation limit of the soft colloid 2, and further improve the installation stability of the soft colloid 2.

[0045] In this embodiment, if Figure 2 As shown, the limiting grooves 24 and the limiting columns 11b are arranged in a one-to-one correspondence to form a limiting group, and the limiting group is provided in plurality and is arranged at intervals along the circumference of the soft colloid 2.

In this way, the operation panel 1 is detachably connected to the mounting plate 31, the housing and other parts by screws, so as to facilitate the disassembly and maintenance of the waterproof key panel 100.

[0047] In this embodiment, the material of the operation panel 1 includes plastic, which is beneficial to the lightweight design of the waterproof key panel 100 .

[0048] In this embodiment, if Figure 1As shown, the bottom wall of the receiving groove 11 is provided with an installation opening; the waterproof key panel 100 further includes a display screen 4, which is arranged in the receiving groove 11, and its screen is exposed at the installation opening. In this way, information display can be realized through the display screen 4, thereby improving the practicality of the waterproof key panel 100.
