[0034] Laboratory equipment has high requirements for miniaturization and automation. For the application scenario of opening and closing the clamp cover that requires automatic control, currently, two linear motors are needed to drive two clamp hoops to cover respectively, so as to realize the opening and closing actions. The problem with this structure is that it requires a large amount of planar space, including the space of the motors themselves and the stroke space required for the double clamp opening and closing actions, which cannot meet the miniaturization requirements of laboratory equipment.

[0035] The technical solution of the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0036] Please refer to Figure 1 and Figure 2 , this embodiment discloses a clamp type opening and closing structure, including a support plate 100, a first sliding mechanism 200, a second sliding mechanism 300, a clamp body 400 and a driving member 500. The first sliding mechanism 200 is connected with a first pull rod 210; the second sliding mechanism 300 is connected with a second pull rod 310; the clamp body 400 includes a first clamp cover 410 and a second clamp cover 420, the first clamp cover and the second clamp cover are arranged oppositely and are both installed on the first side of the support plate, the first clamp cover 410 is connected with the first sliding mechanism 200, and the second clamp cover 420 is connected with the second sliding mechanism 300; the driving member 500 is installed on the second side of the support plate 100 and is located between the first sliding mechanism and the second sliding mechanism, and the output end of the driving member 500 is connected with the first pull rod 210 and the second pull rod 310. The driving member 500 is used to drive the first sliding mechanism 200 and the second sliding mechanism 300 to move towards each other or away from each other. By using a central driving member 500, a first pull rod 210 and a second pull rod 310, the two clamp covers are automatically connected, so that the telescopic action of the driving member 500 is associated with the opening and closing actions of the first clamp cover 410 and the second clamp cover 420. The installation and operation of the whole structure only require the space of the components themselves, and the switching action only requires a small stroke space. The structure is compact and space-saving, meeting the miniaturization requirements of laboratory equipment.

[0037] Embodiment 1, please refer to Figure 2, the output end of the driving member 500 is a telescopic shaft, and the power direction of the output end of the driving member 500 is parallel to the support plate 100. The first pull rod 210 is connected to the first suspension plate 220, and the second pull rod 310 is connected to the second suspension plate 320. The length directions of the first pull rod 210 and the second pull rod 310 are both parallel to the support plate 100. The first pull rod 210 rotates freely around the connection point of the first suspension plate 220, and the second pull rod 310 rotates around the connection point of the second suspension plate 320, driving the first sliding mechanism 200 and the second sliding mechanism 300 to move towards or away from each other. The first clamping cover 410 moves along with the first suspension plate 220 and the second clamping cover 420 also moves along with the second suspension plate 320, thereby realizing the closing or opening action. The power direction of the output end of the driving member 500 is parallel to the support plate 100, and the overall structure is of low height, saving space and meeting the requirements of miniaturization of laboratory equipment.

[0038] Example 2, please refer to Figure 3 , the difference between the second embodiment and the first embodiment is that the power direction of the output end of the driving member 500 is perpendicular to the support plate 100. The first pull rod 210 is connected to the first suspension plate 220, and the second pull rod 310 is connected to the second suspension plate 320. The length direction of the first pull rod 210 forms an angle with the first suspension plate 220, and the length direction of the second pull rod 310 forms an angle with the second suspension plate 320. The structure is compact, reducing the occupied area and adapting to a relatively narrow installation space.

[0039] Example 3, please refer to Figure 4 , the difference between the third embodiment and the second embodiment is that the output end of the driving member 500 is a rotating shaft, and the rotation plane of the rotating shaft is parallel to the support plate 100. The first side of the rotating shaft is connected to the first pull rod 210, and the second side of the rotating shaft is connected to the second pull rod 310. The telescopic space of the telescopic shaft of the driving member 500 is reduced, thereby further saving space.

[0040] Please refer to Figure 2 , the first sliding mechanism 200 includes a first suspension plate 220, a first guide rail 230 and a first slider 240. The first slider 240 is arranged on the first guide rail 230, and the first suspension plate 220 is installed on the first slider 240. The second sliding mechanism 300 includes a second suspension plate 320, a second guide rail 330 and a second slider 340. The second slider 340 is arranged on the second guide rail 330, and the second suspension plate 320 is installed on the second slider 340. The first suspension plate 220 is installed on the first slider 240 so that the first suspension plate 220 slides along with the first slider 240; the second suspension plate 320 is installed on the second slider 340 so that the second suspension plate 320 slides along with the second slider 340. Through the first guide rail 230 and the second guide rail 330, the friction is reduced, ensuring that the first suspension plate 220 and the second suspension plate 320 move in a predetermined direction, realizing high-precision linear movement.

[0041] Please refer to Figure 2 , the first guide rail 230 is a single-rail structure or a multi-rail structure, and the second guide rail 330 is a single-rail structure or a multi-rail structure. The single-rail structure or the multi-rail structure can be adopted according to the actual installation space of the clamp-type opening and closing structure. If the installation space is large, the multi-rail structure is adopted, and the first suspension plate 220 and the second suspension plate 320 move more smoothly.

[0042] Please refer to Figure 2 , the first suspension plate 220 is provided with a first bolt 221, and the first suspension plate 220 is connected to the first clamping cover 410 through the first bolt 221. The second suspension plate 320 is provided with a second bolt 321, and the second suspension plate 320 is connected to the second clamping cover 420 through the second bolt 321.

[0043] Specifically, the first suspension plate 220 is provided with 3 first bolts 221, which are respectively located at both ends and the middle of the first suspension plate 220; the second suspension plate 320 is also provided with 3 second bolts 321, which are respectively located at both ends and the middle of the second suspension plate 320. The first clamping cover 410 and the second clamping cover 420 are installed on the other side of the support plate 100, that is, not on the same side as the driving member 500. The first clamping cover 410 is connected to the first suspension plate 220 through the first bolt 221, and the second clamping cover 420 is connected to the second suspension plate 320 through the second bolt 321. Since the first suspension plate 220 is fixedly connected to the first clamping cover 410 and the second suspension plate 320 is fixedly connected to the second clamping cover 420, the first clamping cover 410 moves towards the middle along with the first suspension plate 220 and the second clamping cover 420 also moves towards the middle along with the second suspension plate 320, thereby realizing the closing action; since the first suspension plate 220 is fixedly connected to the first clamping cover 410 and the second suspension plate 320 is fixedly connected to the second clamping cover 420, the first clamping cover 410 moves towards both sides along with the first suspension plate 220 and the second clamping cover 420 also moves towards both sides along with the second suspension plate 320, thereby realizing the opening action.

[0044] Please refer to Figure 2 , a connecting rod 510 is connected to the output end of the driving member 500. The connecting rod 510 is provided with a connecting rod bolt 222. The first pull rod 210 and the second pull rod 310 are respectively connected to the connecting rod 510 through the connecting rod bolt 222. The first pull rod 210 and the second pull rod 310 can rotate freely around the connecting rod bolt 222; the first pull rod 210 and the second pull rod 310 are respectively sleeved and connected to the first suspension plate 220 and the second suspension plate 320; nuts are used for fixation to prevent the first pull rod 210 and the second pull rod 310 from falling off.

[0045] Please refer to Figure 5, the support plate 100 is provided with a plurality of sliding grooves 101, and the first bolt 221 and the second bolt 321 are respectively inserted into the plurality of sliding grooves 101. When the driving member 500 extends the push rod 211, it pushes the connecting rod 510 to move. The first bolt 221 slides in the sliding groove 101, and the second bolt 321 also slides in the sliding groove 101, thereby driving the first hanging plate 220 and the second hanging plate 320 to move towards the middle. When the driving member 500 contracts the push rod 211, it pulls the connecting rod 510 to move, thereby driving the first hanging plate 220 and the second hanging plate 320 to move towards both sides.

[0046] Please refer to Figure 5 , the support plate 100 is provided with a motor mounting platform 110 and a push rod mounting platform 120. Both the motor mounting platform 110 and the push rod mounting platform 120 are arranged in the middle of the support plate 100. The first end of the driving member 500 is mounted on the motor mounting platform 110, and the second end of the driving member 500 is mounted on the push rod mounting platform 120. The driving member 500 is mounted on the motor mounting platform 110 and the push rod mounting platform 120, and the whole driving member 500 is fixed on the support plate 100. Limiting protrusions 121 are arranged on both sides of the push rod mounting platform 120 to limit the driving member 500 on the push rod mounting platform 120, so that the driving member 500 is further fixed firmly.

[0047] Please refer to Figure 6 , the clamp body 400 further includes a top cover 430. The top cover 430 is mounted under the support plate 100, and the top cover 430 is located between the first clamping cover 410 and the second clamping cover 420. The top cover 430 is mounted under the support plate 100 and is on the same plane as the first clamping cover 410 and the second clamping cover 420. When the support plate 100 moves up and down, automatic opening and closing of the cover can be realized.

[0048] This embodiment also discloses an experimental device, including the above-mentioned clamp-type opening and closing structure.

[0049] Please refer to Figure 7 , when the driving member 500 extends the push rod 211, it pushes the connecting rod 510 to move, thereby driving the first hanging plate 220 and the second hanging plate 320 to move towards the middle. Since the first hanging plate 220 is fixedly connected to the first clamping cover 410 and the second hanging plate 320 is fixedly connected to the second clamping cover 420, the first clamping cover 410 moves towards the middle along with the first hanging plate 220 and the second clamping cover 420 also moves towards the middle along with the second hanging plate 320, thereby realizing the closing action.

[0050] Please refer to Figure 1When the driving member 500 contracts the push rod 211, it pulls the connecting rod 510 to move, thereby driving the first suspension plate 220 and the second suspension plate 320 to move to both sides. Since the first suspension plate 220 is fixedly connected to the first clamping cover 410 and the second suspension plate 320 is fixedly connected to the second clamping cover 420, the first clamping cover 410 moves to both sides along with the first suspension plate 220 and the second clamping cover 420 also moves to both sides along with the second suspension plate 320, thus realizing the opening action.

[0051] By adopting a central driving member 500, a first pull rod 210 and a second pull rod 310, the two clamp covers are automatically connected, so that the telescopic action of the driving member 500 is associated with the opening and closing actions of the first clamping cover 410 and the second clamping cover 420. The installation and operation of the whole structure only require the space of the components themselves, and the switching action only requires a small stroke space, with a compact structure and space saving. By controlling the driving member 500 to extend or contract the push rod 211, the actions of automatically closing or opening the first clamping cover 410 and the second clamping cover 420 are realized, with a complete automatic action. If the top cover 430 is installed under the support plate 100 at the same time and is on the same plane as the first clamping cover 410 and the second clamping cover 420, when the support plate 100 moves up and down, automatic opening and closing of the cover can be realized, thus integrating the full automation functions of opening, closing, opening the cover and closing the cover, meeting the application scenarios of the lid-equipped experimental equipment that requires clamp connection and the applications with the need for automatic control of opening and closing the cover.

[0052] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
