Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the present invention, the distal end refers to the end away from the rotating member 10, and the proximal end refers to the end close to the rotating member 10. Movement along the first direction refers to movement away from the rotating member 10, and movement along the second direction refers to movement close to the rotating member 10.

[0026] like Figures 1-8 As shown, the present invention provides a clamping structure 200 for an oscillator 100. The clamping structure 200 includes a rotating member 10, two pushing components 20, and two clamping components 40. The rotating member 10 is rotatably mounted on the oscillator 100, and its two ends are pivotally connected to the two pushing components 20 respectively. The two pushing components 20 are respectively connected to the two clamping components 40. During operation, one of the pushing components 20 is pushed, causing the rotating member 10 to rotate. The rotating member 10 pushes the other pushing component 20 to move, thereby driving the two clamping components 40 to clamp or release the experimental instrument (not shown) on the support 300.

[0027] In this embodiment, the rotating component 10 is connected to two pushing components 20 at both ends. The two pushing components 20 move in conjunction with the rotating component 10. The pushing components 20 drive the clamping components 40 to move. The structure is simple and ensures the consistency of the actions of the two clamping components 40, which effectively improves the clamping reliability of the oscillator 100 and has strong practicality. At the same time, this method only requires one power source to drive it, which can reduce product costs and facilitate product miniaturization design.

[0028] Furthermore, the rotating component 10 and the two pushing components 20 are arranged to form a parallelogram, and the bearing seat 300 is located within the parallelogram. The rotating component 10 and the two pushing components 20 are arranged in a parallelogram shape, which makes assembly simple and further reduces the installation difficulty of the clamping structure 200, avoiding abnormal operation of the oscillator 100 due to installation deviation.

[0029] In one embodiment, the rotating member 10 is a rotating rod with a rotating part 11 in the middle, and the rotating rod rotates around the rotating part 11; both pushing assemblies 20 include a push rod 21 and a limiting assembly 22, the two ends of the rotating rod are pivotally connected to the two push rods 21 respectively, one clamping assembly 40 is disposed at the free end of one push rod 21, and the other clamping assembly 40 is installed at the connection between the other push rod 21 and the rotating rod; when the rotating rod rotates around the rotating part 11, the two push rods 21 are axially displaced in opposite directions, driving the two clamping assemblies 40 to clamp or release the experimental instrument on the support 300, and the limiting assembly 22 is used to limit the radial rotation generated when the push rod 21 is axially displaced.

[0030] In this embodiment, the free end refers to the end not connected to the rotating rod. A rotating part 11 is provided at the middle position of the rotating rod, and two push rods 21 are respectively connected to the two ends of the rotating rod, ensuring that the two push rods 21 move the same distance in opposite axial directions. The rotating rod can rotate simply by mounting it on the rotating part 11, simultaneously linking the two push rods 21. The installation is simple and does not require complex angle adjustments to the pushing assembly 20 and the clamping assembly 40, which is beneficial for mass production. The radial rotation of the push rod 21 is restricted by the limiting assembly 22, ensuring a stable connection between the push rod 21 and the clamping assembly 40 and preventing the push rod 21 from flipping.

[0031] Furthermore, the rotating part 11 includes a rotating support shaft disposed on the oscillator 100. A rotating hole is provided in the middle of the rotating rod, and the rotating support shaft passes through the rotating hole to ensure that the rotating rod can rotate relative to the rotating support shaft. A plastic gasket is installed at the connection between the rotating rod and the rotating support shaft to reduce friction between the rotating rod and the rotating support shaft, extend product life, and reduce noise.

[0032] In one embodiment, such as Figures 5-8As shown, the limiting component 22 includes a limiting seat 221 and a limiting groove 211. The limiting seat 221 is disposed on the oscillator 100; the limiting groove 211 is disposed on the push rod 21 and extends along the axial direction of the push rod 21; the limiting seat 221 has a through hole 222 for the push rod 21 to pass through and a limiting boss 223 that can slide relative to the limiting groove 211. The limiting boss 223 and the limiting groove 211 cooperate to limit the radial rotation of the push rod 21. In this embodiment, the length of the limiting groove 211 extends along the axial direction of the push rod 21, and the limiting boss 223 moves axially along the limiting groove 211 to ensure that the push rod 21 moves only in the axial direction. By limiting the radial rotation of the push rod 21, the push rod 21 is prevented from overturning.

[0033] Furthermore, the number of limiting components 22 is four, with two limiting components 22 respectively installed at both ends of one push rod 21, and the other two limiting components 22 installed at both ends of another push rod 21, which helps to improve the stability of the axial displacement of the push rod 21, thereby improving product reliability.

[0034] In one embodiment, the rotating member 10 has a first strip-shaped hole 12 and a second strip-shaped hole (not shown) at both ends; the first strip-shaped hole 12 and a through hole 212 of one of the push rods 21 are connected by a pin 23, and the second strip-shaped hole and a through hole 212 of another push rod 21 are connected by another pin 23. In this embodiment, by providing the first strip-shaped hole 12 and the second strip-shaped hole, the two pins 23 are respectively inserted into the first strip-shaped hole 12 and the second strip-shaped hole, so that the rotating member 10 rotates while the push rod 21 only moves axially, avoiding interference. In this embodiment, the two push rods 21 have through holes 212 at both ends for connecting to the rotating member 10 and the clamping assembly 20.

[0035] In one embodiment, such as Figures 5-8 As shown, both clamping assemblies 40 include connecting rods 60, interconnected couplings 41, and sliding clamping assemblies 42. One push rod 21 has a through hole 212 at its end away from the rotating rod and a pin 23 passing through the through hole 212. The two ends of one connecting rod 60 are respectively connected to one coupling 41 and the pin 23, and the two ends of the other connecting rod 60 are respectively connected to another coupling 41 and the pin 23. In this embodiment, the connecting rod 60 has two connecting holes, and the coupling 41 and the pin 23 pass through the two connecting holes respectively. The push rod 21 drives the sliding clamping assembly 42 to move through the coupling 41 and the connecting rod 60.

[0036] In one embodiment, such as Figure 4 and Figure 6As shown, the sliding clamping assembly 42 includes a slide rail 421 mounted on the oscillator 100, a slider 422 slidably disposed on the slide rail 421, and a clamping member 423 mounted on the slider 422. The slide rail 421 is provided with a clearance groove 424. One end of the coupling 41 is connected to the slider 422, and the other end passes through the clearance groove 424 and is connected to the connecting rod 60. In this embodiment, the clamping member 423 slides smoothly through the cooperation of the slide rail 421 and the slider 422. Further, the clamping member 423 includes a clamping seat and two clamping posts arranged parallel to each other on the clamping seat.

[0037] In one embodiment, such as Figures 1-8 As shown, the clamping structure 200 further includes a gripper 70, a clamping power assembly 80, a first elastic element 90, and / or a second elastic element 91. The gripper 70 is mounted on a push rod 21 and extends through a positioning groove 71 to the oscillator 100. The clamping power assembly 80 is connected to another push rod 21. The first elastic element 90 is sleeved on the push rod 21 connected to the gripper 70, with one end abutting against the gripper 70 and the other end abutting against a limiting assembly 22. Alternatively, the second elastic element 91 is sleeved on the push rod 21 connected to the clamping power assembly 80, with one end abutting against the clamping power assembly 80 and the other end abutting against another limiting assembly 22. In this embodiment, when the clamping assembly 40 is in a released state or a clamped state, the first elastic element 90 and / or the second elastic element 91 are always in a compressed state, greatly improving the safety and reliability of the product.

[0038] Specifically, one end of the elastic element abuts against the gripper 70, and the other end abuts against a limiting component 22 and is fixed to the limiting component 22. The elastic element abutting against the gripper 70 is compressed. During clamping, the push rod 21, which is fixedly connected to the gripper 70, is pushed to move in the second direction. The push rod 21 pulls the sliding clamping component 42 on it to clamp the experimental instrument. At the same time, the push rod 21 pushes the rotating component 11 to rotate. The rotation of the rotating component 11 causes another push rod 21 to move in the first direction. The other push rod 21 pulls the sliding clamping component 42 installed at the connection between the push rod 21 and the rotating rod to clamp the experimental instrument, ensuring that the product can automatically clamp the experimental instrument. Conversely, when the gripper 70 is manually pushed to move in the first direction, the push rod 21, which is fixedly connected to the gripper 70, moves in the first direction, increasing the compression of the first elastic member 90. This pushes the sliding clamping assembly 42 on the first elastic member to release the experimental instrument. At the same time, the push rod 21 pushes the rotating member 11 to rotate. The rotation of the rotating member 11 causes another push rod 21 to move in the second direction, pulling the sliding clamping assembly 42, which is installed at the connection between the push rod 21 and the rotating rod, to release the experimental instrument, thus realizing the manual release of the experimental instrument. At this time, if the gripper 70 is released, the two sliding clamping assemblies 42 automatically clamp the experimental instrument under the action of the elastic member.

[0039] Alternatively, the clamping power assembly 80 moves in the second direction, pushing the connected push rod 21 to move in the second direction and compressing the second elastic member 91 that abuts against it; the push rod 21 pushes the sliding clamping assembly 42 on it to release the experimental instrument, and at the same time, the push rod 21 pushes the rotating member 11 to rotate, causing another push rod 21 to move in the first direction, and the other push rod 21 pushes the sliding clamping assembly 42 on it to release the experimental instrument. Conversely, the clamping power assembly 80 moves in the first direction, pushing the connected push rod 21 to move in the first direction, and the push rod 21 pulls the sliding clamping assembly 42 on it to clamp the experimental instrument, and at the same time, the push rod 21 pushes the rotating member 11 to rotate, causing another push rod 21 to move in the second direction, and the other push rod 21 pulls the sliding clamping assembly 42 on it to clamp the experimental instrument.

[0040] In another embodiment, a first elastic member 90 is sleeved on the push rod 21 connected to the gripper 70, with one end abutting against the gripper 70 and the other end abutting against a limiting component 22; a second elastic member 91 is sleeved on the push rod 21 connected to the clamping power component 80, with one end abutting against the clamping power component 80 and the other end abutting against another limiting component 22, so as to improve product reliability.

[0041] In one embodiment, such as Figure 4As shown, the clamping power assembly 80 includes a lead screw 83, a lead screw 82, a transmission assembly 85, a motor 854, and a fixing member 81; the lead screw 83 is sleeved on the lead screw 82, the transmission assembly 85 is used to drive the lead screw 82 to rotate, and the transmission assembly 85 is connected to the output shaft of the motor 854; the fixing member 81 is sleeved on the push rod 21 and is located between the lead screw 83 and the second elastic member 91.

[0042] The transmission assembly 85 includes a first transmission wheel 851, a second transmission wheel 852, a transmission belt 853 sleeved on the transmission wheel and the second transmission wheel 852, and a motor 854. The first transmission wheel 851 is connected to the output shaft of the motor 854, and the second transmission wheel 852 is mounted on the lead screw 82.

[0043] For ease of description, the push rod 21 fitted onto the first elastic member 90 is described as the first push rod 21', and the clamping assembly 40 connected to the first push rod 21' is described as the first clamping assembly 40'; the push rod 21 fitted onto the second elastic member 91 is described as the second push rod 21'', and the clamping assembly 40 connected to the second push rod 21'' is described as the second clamping assembly 40''.

[0044] Working principle of clamping structure 200: as follows Figures 1-8As shown, when the first clamping assembly 40' and the second clamping assembly 40'' clamp the experimental instrument, the nut 83 and the fixing member 81 are at the distal end, and the second elastic member 91 is in a compressed state; the gripping member 70 is at the proximal end, and the first elastic member 90 is in a compressed state. The clamping structure 200 of the present invention can release the experimental instrument in both electric and manual modes. In electric mode: Motor 854 drives nut 83 to move in the second direction through transmission assembly 85, pushing fixing member 81 to compress second elastic member 91. Second push rod 21'' moves in the second direction under the action of fixing member 81. Second push rod 21'' pulls sliding clamping assembly 42 of second clamping assembly 40'' away from experimental instrument through connecting rod 60. Second push rod 21'' pushes rotating rod to rotate around rotating part 11. Rotating rod causes first push rod 21' to move in the first direction. First push rod 21' drives sliding clamping assembly 42 of first clamping assembly 40' away from experimental instrument through connecting rod 60 to release experimental instrument. In manual mode, the gripper 70 is manually pushed to move in the first direction, the first elastic member 90 between the gripper 70 and the limiting component 22 is compressed, the first push rod 21' moves with the gripper 70 in the first direction, the rotating rod rotates and drives the second push rod 21'' to move in the second direction, and the sliding clamping component 42 of the first clamping component 40' and the second clamping component 40'' moves away from the experimental instrument to release the experimental instrument. Understandably, in electric mode, motor 854 drives nut 83 to move in the first direction via transmission assembly 85. The compressed second elastic element 91 pushes the fixing element 81 to follow nut 83, thereby causing the second push rod 21'' to move in the first direction. The sliding clamping assembly 42 of the second clamping assembly 40'' connected to the second push rod 21'' moves towards the experimental instrument. The rotating rod rotates under the push of the second push rod 21'', which in turn drives the first push rod 21' to move in the second direction. The first push rod 21' causes the sliding clamping assembly 42 of the first clamping assembly 40' to move towards the experimental instrument to clamp it. In manual mode, releasing the gripping element 70 reduces the compression of the first elastic element 90, causing the first push rod 21' to move in the second direction, which drives the rotating rod to rotate. The rotating rod causes the second push rod 21'' to move in the first direction, causing the sliding clamping assembly 40' and the sliding clamping assembly 42 of the second clamping assembly 40' to move towards the experimental instrument to clamp it.

[0045] As one embodiment, the clamping structure 200 further includes a guide member 84, which is arranged along the axial direction of the push rod 21. The nut 83 cooperates with the guide member 84 to allow the nut 83 to move axially. In this embodiment, the guide member 84 is arranged along the axial direction of the push rod 21 and includes a slider and a slide rail that cooperate with each other. The nut 83 is connected to the slider and moves along the slide rail to allow the nut 83 to move stably along the axial direction of the push rod 21, avoiding deviation and ensuring the reliability of the movement.

[0046] As one embodiment, the clamping structure 200 further includes a release detection component, which determines whether the two clamping components 40 release the experimental instrument by detecting the position of the nut 83.

[0047] Specifically, the release detection component includes, but is not limited to, an optical coupler detection component, an infrared sensor detection component, and an image detection component. Further, the release detection component includes a release optical coupler and a release optical coupler baffle. The release optical coupler baffle is disposed on the nut 83, and the release optical coupler is disposed on the oscillator 100. The release optical coupler baffle moves with the nut 83. When the release optical coupler baffle is opposite to the release optical coupler, the two clamping components 40 reach the position of the release experimental instrument, realizing intelligent position detection. The release detection component also includes a signal generator. When the release optical coupler baffle is opposite to the release optical coupler, the signal generator triggers a signal to inform the user that the two clamping components 40 have reached the position of the release experimental instrument. This signal can be a constantly lit indicator light, a flashing indicator light, an audible sound, or a voice announcement, etc., and is not limited thereto. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
