DETAILED DESCRIPTION

[0021] The following will be combined with 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 of 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.

[0022] refer to Figure 1-5 , an anti-interference AC / DC data collector, comprising a shell 1, a dustproof net 101, a dustproof groove 102 is provided on the side of the shell 1, the dustproof net 101 is arranged in the dustproof groove 102, a positioning block 103 is provided at the bottom of the dustproof groove 102, a fixing mechanism for fixing the dustproof net 101 is provided inside the positioning block 103, both sides of the dustproof groove 102 are provided with telescopic components for fixing the dustproof net 101, and a mounting frame 104 is provided around the dustproof net 101. By setting the mounting frame 104, the dustproof net 101 can be more easily cleaned and replaced. When the dustproof net 101 becomes dirty or damaged, it is only necessary to simply remove the mounting frame 104, remove the old dustproof net 101, and install a new dustproof net 101 or clean it without complicated processing of the entire data collector. The fixing mechanism is used for one side of the dustproof net 101, and the telescopic component is used to fix the other side of the dustproof net 101.

[0023] Positioning frames 105 are provided on both sides of the bottom of the installation frame 104. When the staff installs the dustproof net 101, the positioning frames 105 can help the staff to quickly position the dustproof net 101, making it convenient for the staff to quickly install the dustproof net 101. The opposite sides of the two positioning frames 105 are provided with a first fixing hole 106 that is slidably connected to the fixing mechanism, and the top of the installation frame 104 is provided with a second fixing hole 107 that is slidably connected to the telescopic component.

[0024] In this embodiment, the fixing mechanism includes a fixing plate 2, a first elastic member 201, and a plurality of fixing blocks 202. A accommodating space 203 is provided inside the positioning block 103. Fixed grooves 204 are provided on both sides of the accommodating space 203. Each fixing block 202 has at least two, and the two fixing blocks 202 are respectively arranged inside the fixing grooves 204 and are slidably connected to the inner walls of the fixing grooves 204. The fixing plate 2 is arranged inside the accommodating space 203 and is slidably connected to the inner walls of the accommodating space 203. The opposite sides of the two fixing blocks 202 are rotatably connected to the two sides of the fixing plate 2 through one end of a plurality of connecting rods 205, and the other end of the connecting rod 205 is rotatably connected to the fixing block 202.

[0025] A fixing rod 206 is provided at one end of the fixing plate 2 away from the fixing block 202. The side of the fixing rod 206 away from the fixing plate 2 passes through the side of the positioning block 103 and extends to the outside of the positioning block 103. One end of the first elastic member 201 abuts against the fixing plate 2, and the other end of the first elastic member 201 abuts against the inner wall of the accommodating space 203. When the staff pulls the fixing rod 206 outward, the fixing rod 206 will move in the direction of compressing the elastic member, and the fixing rod 206 will drive the fixing plate 2 to slide against the inner wall of the accommodating space 203. At the same time, the fixing plate 2 will drive the fixing block 202 to slide in the fixing groove 204 through a plurality of connecting rods 205. In order to limit the self-slip of the fixing plate 2 Therefore, a guide groove 402 is set at the top of the accommodating space 203, and a guide block 401 is set at the top of the fixed plate 2, and the guide block 401 is slidably connected to the inner wall of the guide groove 402. The guide block 401 and the guide groove 402 limit the freedom of the fixed plate 2, so that the fixed plate 2 can only move forward and backward, thereby improving the stability of the fixing mechanism. When the fixed block 202 is retracted into the fixed groove 204, the fixed block 202 will be separated from the first fixing hole 106 and slidably connected to the inner wall of the first fixing hole 106. When the fixed block 202 is separated from the first fixing hole 106, the staff only needs to overcome the reset force of the second elastic member 3 to remove the dustproof net 101.

[0026] In this embodiment, in order to facilitate the staff to quickly position the dustproof net 101, the positioning block 103 is extended to the outside of the dustproof groove 102 at one end away from the fixing block 202, and a handle 207 is provided on the side of the fixing rod 206 away from the fixing plate 2. The handle 207 can increase the contact area between the staff and the fixing rod 206, thereby facilitating the staff to install the dustproof net 101, and extend the positioning block 103 to the outside of the dustproof groove 102. When the staff needs to install the dustproof net 101, the gap between the two positioning frames 105 is matched with the positioning block 103, so that the dustproof net 101 can be pre-installed and quickly positioned. Then, the positioning frame 105 only needs to be pushed into the dustproof groove 102 to complete the installation.

[0027] In this embodiment, in order to realize the rapid installation and disassembly of the dustproof net 101, the telescopic assembly includes a second elastic member 3 and a telescopic block 301. Telescopic grooves 302 are provided on both sides of the dustproof groove 102. One end of the second elastic member 3 abuts against the bottom of the telescopic groove 302, and the other end of the second elastic member 3 abuts against the telescopic block 301. The telescopic block 301 extends out of the telescopic groove 302. The end of the telescopic block 301 away from the second elastic member 3 is in an arc shape. The cross-section of the second fixing hole 107 is in a triangular structure. One end of the telescopic block 301 in an arc shape is slidably connected to the second fixing hole 107. The side of the installation frame 104 close to the bottom of the dustproof groove 102 is in an arc shape.

[0028] When the staff needs to remove the dust screen 101, they only need to hold the handle 207 and pull it in the direction away from the positioning block 103. The handle 207 will drive the fixing rod 206 to move, so that the fixing plate 2 moves in the direction of the compressed elastic member. Since the fixing block 202 is rotatably connected to the fixing plate 2 through the connecting rod 205, when the fixing plate 2 moves in the direction of the compressed elastic member, the fixing plate 2 will drive the fixing block 202 to move in the fixing groove 204 through the connecting rod 205, so that the two fixing blocks 202 move in the direction of approaching each other, so that the two fixing blocks 202 are separated from the first A fixing hole 106. When the fixing block 202 is separated from the first fixing hole 106, a plurality of balls 4 are arranged on the inner wall of the fixing groove 204 to reduce friction. The balls 4 can reduce the friction between the fixing block 202 and the fixing groove 204, thereby facilitating the staff to disassemble the dustproof net 101. Since one end of the telescopic block 301 is in an arc-shaped structure and is slidably connected to the second fixing hole 107, the staff only needs to overcome the force of the second elastic member 3 to take out the dustproof net 101 and clean it. The staff only needs to pull the handle 207 to release the fixation of the two fixing blocks 202 on the dustproof net 101. The operation is convenient and the practicality is improved.

[0029] When the staff needs to install the dustproof net 101, the gap between the two positioning frames 105 is matched with the positioning block 103. Since the side of the installation frame 104 close to the bottom of the dustproof groove 102 is an arc-shaped structure, when the installation frame 104 is pushed into the dustproof groove 102, the end of the telescopic block 301 with an arc-shaped structure will slide with the installation frame 104 and compress the second elastic member 3. When the second fixing hole 107 moves to the telescopic block 301, under the action of the second elastic member 3, the telescopic block 301 will extend into the second fixing hole 107 and fix the installation frame 104.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
