The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0029] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0030] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0031] refer to Figures 1 to 7 A dustproof device according to a preferred embodiment of the present invention will be described in detail below. The dustproof device includes a door device 10 and a device body 20.

[0032] The device body 20 defines an active space 201 and an inlet and outlet 202 communicating with the active space 201. The door device 10 includes a door member 11, at least one connecting mechanism 12, and a sealing member 13. The connecting mechanism 12 includes a first assembly component 121 and a second assembly component 122, wherein the first assembly component 121 is rotatably mounted on the second assembly component 122.

[0033] The door member 11 forms at least one first hidden groove 1101, and the first assembly component 121 is concealedly installed in the first hidden groove 1101. The wall of the inlet and outlet 202 is recessed inward to form at least one second hidden groove 203, and the second assembly component 122 is concealedly installed in the second hidden groove 203. The door member 11 opens or closes the inlet and outlet 202 by flipping the first assembly component 121 relative to the second assembly component 122. When the door member 11 closes the inlet and outlet 202, the door member 11 is embedded in the inlet and outlet 202. At this time, the second hidden groove 203 is opposite to the first hidden groove 1101, and the first assembly component 121 and the second assembly component 122 remain opposite to each other and abut against each other, thereby reducing the gap between the door member 11 and the device body 20, thereby improving the sealing performance of the dustproof device. Since the second assembly component 122 and the first assembly component 121 are respectively hidden in the second hidden groove 203 and the first hidden groove 1101, the connecting mechanism 12 does not occupy the activity space 201 or is not exposed to the outside, thereby preventing the connecting mechanism 12 from interfering with other devices.

[0034] The sealing member 13 is surrounded by the periphery of the door member 11, and when the door member 11 covers the inlet and outlet 202, the sealing member 13 blocks the gap between the door member 11 and the device body 20, so that the activity space 201 is sealed, further preventing external dust and the like from entering the activity space 201 through the gap between the door member 11 and the device body 20, and avoiding interference of dust and the like on the operation of the equipment located in the activity space 201.

[0035] In one example, the sealing element 13 is implemented as a rubber ring.

[0036] In a preferred embodiment, the door member 11 includes a door frame and glass. The sealing member 13 is disposed around the periphery of the door frame. The door frame forms a receiving groove, and the glass is fixedly mounted in the receiving groove, allowing outsiders to observe the operating status of the equipment within the activity space 201 through the glass.

[0037] Specifically, the first assembly component 121 includes a first assembly body 1211, at least one first connecting component 1212, and a first pivot axis 1213. The second assembly component 122 includes a second assembly body 1221, at least one second connecting component 1222, and a second pivot axis 1223. The first assembly body 1211 is fixedly mounted in the first hidden slot 1101. The second assembly body 1221 is fixedly mounted in the second hidden slot 203.

[0038] The first assembly body 1211 forms a first sliding channel 121101 and a first mounting groove 121102, wherein the first sliding channel 121101 extends in the same direction as the first hidden groove 1101. The second assembly body 1221 forms a second sliding channel 122101 and a second mounting groove 122102, wherein the second sliding channel 122101 extends in the same direction as the second hidden groove 203. One end of the first connecting component 1212 extends into the first mounting groove 121102 and is rotatably connected to the first assembly body 1211 via the first pivot axis 1213. The end of the first connecting component 1212, which is away from the first pivot axis 1213, is slidably mounted on the second sliding channel 122101. One end of the second connecting component 1222 extends into the second installation groove 122102 and is rotatably connected to the second assembly body 1221 through the second pivot shaft 1223 . One end of the second connecting component 1222 away from the second pivot shaft 1223 is slidably installed in the first sliding channel 121101 .

[0039] In this way, when the door member 11 drives the first assembly 1211 to rotate and move in the direction of opening the inlet and outlet 202, the first connecting component 1212 slides in the direction of pulling out the second hidden groove 203, and at the same time, the first connecting component 1212 rotates relative to the first assembly 1211 with the first pivot axis 1213 as the axis; the second connecting component 1222 rotates relative to the second assembly 1221 with the second pivot axis 1223 as the axis, and at the same time, the second connecting component 1222 slides in the direction of pulling out the first hidden groove 1101. When the door member 11 drives the first assembly 1211 to rotate and close the inlet and outlet 202, the first connecting component 1212 slides in the direction of deepening into the second hidden groove 203, and at the same time, the first connecting component 1212 rotates relative to the first assembly 1211 with the first pivot axis 1213 as the axis; the second connecting component 1222 rotates relative to the second assembly 1221 with the second pivot axis 1223 as the axis, and at the same time, the second connecting component 1222 slides in the direction of deepening into the first hidden groove 1101.

[0040] It can be understood that since the first pivot axis 1213 and the second pivot axis 1223 are respectively retained in the first mounting groove 121102 and the second mounting groove 122102, and when the door member 11 closes the inlet and outlet 202, the first connecting component 1212 and the second connecting component 1222 are hidden in the second sliding channel 122101 and the first sliding channel 121101, the first assembly 1211 and the second assembly 1221 can abut against each other to reduce the gap between the door member 11 and the equipment body 20.

[0041] Preferably, the first connecting assembly 1212 includes a first curved arm 12121. One end of the first curved arm 12121 is connected to the first pivot axis 1213, and the end of the first curved arm 12121 away from the first pivot axis 1213 is slidably mounted in the second sliding channel 122101. The second connecting assembly 1222 includes a second curved arm 12221. One end of the second curved arm 12221 is connected to the second pivot axis 1223, and the end of the second curved arm 12221 away from the second pivot axis 1223 is slidably mounted in the first sliding channel 121101. The first sliding channel 121101 and the second sliding channel 122101 define the movement directions of the second curved arm 12221 and the first curved arm 12121, respectively.

[0042] Preferably, the first assembly 1211 further defines a first side opening 121103 that communicates with the first sliding channel 121101. When the first assembly 1211 is installed in the first hidden groove 1101, the sidewalls of the first hidden groove 1101 block the first side opening 121103, allowing the first hidden groove 1101 and the first sliding channel 121101 to cooperatively define the sliding trajectory of the second curved arm 12221. This eliminates the need for additional structure on the side of the first assembly 1211 forming the first side opening 121103, reducing the size of the first assembly 1211 and the manufacturing cost of the first assembly 1211.

[0043] Also preferably, the second assembly 1221 further defines a second side opening 122103 that communicates with the second sliding channel 122101. When the second assembly 1221 is installed in the second hidden groove 203, the sidewalls of the second hidden groove 203 block the second side opening 122103, allowing the second hidden groove 203 and the second sliding channel 122101 to cooperatively define the sliding trajectory of the first curved arm 12121. This eliminates the need for additional structure on the side of the second assembly 1221 that forms the second side opening 122103, reducing the size of the second assembly 1221 and the manufacturing cost of the second assembly 1221.

[0044] Furthermore, the first connecting assembly 1212 also includes a first sliding post 12122. The axial direction of the first sliding post 12122 is parallel to the axial direction of the first pivot axis 1213. The first sliding post 12122 is mounted on an end of the first crank arm 12121 away from the first pivot axis 1213. Two second limiting grooves 122104 are also formed on the inner wall of the second sliding channel 122101. The two second limiting grooves 122104 are arranged opposite each other and arranged in a direction perpendicular to the extension direction of the second sliding channel 122101. The extension direction of the second limiting grooves 122104 is parallel to the extension direction of the second sliding channel 122101. The two ends of the first sliding post 12122 are respectively inserted into one of the second limiting grooves 122104. When the door member 11 drives the first assembly 1211 to flip, the first assembly 1211 drives the first sliding post 12122 to move along the extension direction of the second limiting groove 122104 via the first crank arm 12121. It is worth mentioning that the first connecting component 1212 is retained in the second sliding channel 122101 under the restraint of the second limiting groove 122104.

[0045] In a preferred embodiment, the second assembly 1221 further defines an access port 122105 in communication with the second limiting groove 122104. The second limiting groove 122104 has a closed end 1221041 that opposes the access port 122105 and is located adjacent to the opening of the second hidden groove 203. The closed end 1221041 is located in the sliding path of the first sliding post 12122. When the first sliding post 12122 abuts the closed end 1221041, the door 11 rotates to open the access port 202 to its maximum angle. At this point, the closed end 1221041 prevents the first sliding post 12122 from moving out of the second limiting groove 122104 and separating from the second assembly 1221. When the first slide post 12122 abuts the wall of the second hidden groove 203 through the access port 122105, the door member 11 rotates to completely cover the access port 202. In other words, the closed end 1221041 and the inner wall of the second hidden groove 203 jointly limit the travel range of the first slide post 12122. Furthermore, the end of the second assembly 1221 that forms the access port 122105 does not require any additional structure, resulting in a smaller size of the second assembly 1221, thereby reducing the manufacturing cost of the second assembly 1221.

[0046] Furthermore, the second connecting assembly 1222 also includes a second sliding post 12222. The axial direction of the second sliding post 12222 is parallel to the axial direction of the second pivot axis 1223. The second sliding post 12222 is mounted on an end of the second crank arm 12221 away from the second pivot axis 1223. Two first limiting grooves 121104 are also formed on the inner wall of the first sliding channel 121101. The two first limiting grooves 121104 are arranged opposite each other and arranged in a direction perpendicular to the extension direction of the first sliding channel 121101. The extension direction of the first limiting grooves 121104 is parallel to the extension direction of the first sliding channel 121101. The two ends of the second sliding post 12222 are respectively inserted into one of the first limiting grooves 121104. When the door member 11 drives the first assembly 1211 to flip, the second crank arm 12221 drives the second sliding post 12222 to move along the extension direction of the first limiting groove 121104. It is worth mentioning that the second connecting component 1222 is limited by the first limiting groove 121104 and remains moving in the first sliding channel 121101.

[0047] In a preferred embodiment, the first assembly 1211 further defines a free port 121105 in communication with the first limiting groove 121104. The first limiting groove 121104 includes a retaining end 1211041 positioned opposite the free port 121105 and adjacent to the opening of the first hidden groove 1101. The retaining end 1211041 is positioned along the sliding path of the second sliding post 12222. When the second sliding post 12222 abuts the retaining end 1211041, the door member 11 rotates to open the access port 202 to its maximum angle. At this point, the retaining end 1211041 prevents the second sliding post 12222 from moving out of the first limiting groove 121104 and separating from the first assembly 1211. When the second slide post 12222 abuts the wall of the first hidden groove 1101 through the free port 121105, the door member 11 rotates to completely cover the inlet and outlet 202. In other words, the retaining end 1211041 and the inner wall of the first hidden groove 1101 jointly limit the travel range of the second slide post 12222, and no structure is required on the end of the first assembly 1211 forming the free port 121105, thereby reducing the size of the first assembly 1211 and thereby reducing the manufacturing cost of the first assembly 1211.

[0048] Furthermore, the connecting mechanism 12 further includes a connecting shaft 123. The first crank arm 12121 and the second crank arm 12221 are pivotally connected via the connecting shaft 123, and the connecting shaft 123 is used to improve the stability of the first crank arm 12121 and the second crank arm 12221 when they rotate.
