Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a multifunctional sensing jaw for an analyzer. Background Art

[0002] Sample analyzers are now widely used in hospitals at all levels, medical testing laboratories, and regional testing centers due to their fast measurement speed, high accuracy, and small reagent consumption.

[0003] Most of the existing sample analyzers include a clamping claw assembly for clamping objects. The clamping surfaces of the clamping claws on some existing sample analyzers are generally flat or curved. Since the flat clamping surface is suitable for clamping objects with flat sides, and the curved clamping surface is suitable for clamping cylindrical goods, when the clamping claw with a flat clamping surface is used to clamp a cylindrical object or when the clamping claw with a curved clamping surface is used to clamp an object with a flat side, the clamping effect is poor and the clamping is unstable. Therefore, the existing technology can only stably clamp objects of one shape, and the function is relatively single, which reduces the scope of application of the device.

[0004] In summary, how to enable the clamp to firmly clamp both cylindrical objects and objects with flat sides is a technical problem that needs to be solved urgently. To this end, we propose a multifunctional sensor clamp for an analyzer. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a multifunctional sensing clamp for an analyzer, comprising a cross bar, a connecting frame fixedly connected to the bottom side of the cross bar, a groove is provided on the top of the cross bar, a driving assembly is arranged inside the groove, two matching sliding blocks are symmetrically and slidably connected inside the groove, an installation cavity is provided inside the sliding block, a rotating hole is provided on the top of the sliding block, a rotating motor is fixedly connected inside the installation cavity, a rotating shaft is rotatably connected inside the rotating hole, an output end of the rotating motor extends to the inside of the rotating hole and is fixedly connected to the rotating shaft, two rotating plates are symmetrically and slidably connected to the top of the cross bar, two rectangular plates are arranged between the two rotating plates, clamping plates are arranged on opposite sides of the two rotating plates, pressure sensors are fixedly connected between the rotating plate and the rectangular plate and between the rotating plate and the clamping plate, and an arc-shaped clamping groove is provided on the surface of the clamping plate.

[0006] According to the technical solution provided in the embodiment of the present application, the driving assembly includes a servo motor and a bidirectional screw rod, the inner rotation of the groove is connected to the bidirectional screw rod, and the two sliding blocks are symmetrically threaded on the outer side of the bidirectional screw rod, and the outer side of the cross bar is fixedly connected to the servo motor for driving the bidirectional screw rod to rotate.

[0007] According to the technical solution provided in the embodiment of the present application, the rotating hole is communicated with the mounting cavity, and the top end of the rotating shaft is fixedly connected to the middle part of the bottom end surface of the rotating plate.

[0008] According to the technical solution provided in the embodiment of the present application, a second battery is fixedly connected to the left side of the bottom end surface of the cross bar, and the outer sides of the two sliding blocks are fixedly connected to the first battery.

[0009] According to the technical solution provided in the embodiment of the present application, sliding grooves are provided on both the front and rear sides of the inner wall of the groove, and sliding blocks adapted to the sliding grooves are symmetrically fixedly connected to the outer side of the sliding block.

[0010] According to the technical solution provided in the embodiment of the present application, an annular groove is provided on the inner wall of the rotating hole, and an annular sliding block adapted to the annular groove is fixedly connected to the outer side of the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When it is necessary to clamp and fix an object with a flat side surface, the present application controls the two rotating motors to rotate, thereby rotating the two rectangular plates between the two rotating plates, so that the object is clamped and fixed by using the two rectangular plates with flat clamping surfaces, and the clamping and fixing effect is better. When it is necessary to clamp and fix a cylindrical object, the two rotating motors are controlled to work, and the two clamping plates are rotated between the two rotating plates, so that the object is clamped and fixed by using the arc-shaped clamping grooves on the two clamping plates, thereby ensuring the clamping and fixing effect for the cylindrical object. In summary, the present application improves the scope of application of the device and solves the problem of the single function of the clamping claws in the prior art.

[0013] 2. When two rectangular plates or two clamping plates clamp an object, when the pressure value detected by the pressure sensor is greater than the set value, the servo motor is controlled to stop working to avoid damage to the object due to excessive pressure, thereby making the device have a sensing function.

[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] As mentioned in the background technology, the clamping surfaces of the clamps on some sample analyzers in the prior art are generally flat or curved. Since the flat clamping surface is suitable for clamping objects with flat sides, and the curved clamping surface is suitable for clamping cylindrical goods, the clamping effect is not good and the clamping is not stable when the clamping surface of the flat clamping surface is used to clamp cylindrical objects or the clamping surface of the curved clamping surface is used to clamp objects with flat sides. Therefore, there is a problem that the prior art can only stably clamp objects of one shape, the function is relatively single, and the scope of application of the device is reduced.

There is a rotating shaft 16. When it is necessary to clamp and fix an object with a flat side surface, the two rotating motors 11 are controlled to rotate, so that the two rectangular plates 6 are rotated between the two rotating plates 5, so that the two rectangular plates 6 with flat clamping surfaces are used to clamp and fix the object, and the clamping and fixing effect is better. When it is necessary to clamp and fix a cylindrical object, the two rotating motors 11 are controlled to work, and the two clamping plates 7 are rotated between the two rotating plates 5, so that the arc-shaped clamping grooves 8 on the two clamping plates 7 are used to clamp and fix the object, thereby ensuring the clamping and fixing effect of the cylindrical object;

[0022] The output end of the rotating motor 11 extends to the inside of the rotating hole 13 and is fixedly connected to the rotating shaft 16. Two rotating plates 5 are symmetrically and slidably connected to the top of the cross bar 1. Two rectangular plates 6 are arranged between the two rotating plates 5. Clamping plates 7 are arranged on the opposite sides of the two rotating plates 5. Pressure sensors are fixedly connected between the rotating plate 5 and the rectangular plate 6 and between the rotating plate 5 and the clamping plate 7. During operation, a pressure value is set for the pressure sensor. When the pressure value detected by the pressure sensor is greater than the set value, the servo motor 3 is controlled to stop working to avoid excessive pressure from clamping and damaging the object, thereby making the device have a sensing function. An arc-shaped clamping groove 8 is provided on the surface of the clamping plate 7, wherein the pressure sensor, the servo motor 3 and the rotating motor 11 are all externally connected to a controller.

[0023] See also Figure 1 and Figure 2 The driving assembly includes a servo motor 3 and a bidirectional screw 9. The inner part of the groove 4 is rotatably connected with the bidirectional screw 9, and two sliding blocks 15 are symmetrically threadedly sleeved on the outer side of the bidirectional screw 9. The outer side of the cross bar 1 is fixedly connected with a servo motor 3 for driving the bidirectional screw 9 to rotate. The rotating hole 13 is communicated with the mounting cavity 10. The top of the rotating shaft 16 is fixedly connected to the middle part of the bottom end surface of the rotating plate 5. The servo motor 3 drives the bidirectional screw 9 to rotate. The rotation of the bidirectional screw 9 drives the two sliding blocks 15 to move relative to each other inside the groove 4, thereby driving the two rotating plates 5 to move relative to each other, so that the two rectangular plates 6 or the two clamping plates 7 are used to clamp and fix the object.

[0024] See also Figure 1 and Figure 2 A second battery (not shown in the figure) is fixedly connected to the left side of the bottom end surface of the cross bar 1, and the second battery supplies power to the servo motor 3. The outer sides of the two sliding blocks 15 are fixedly connected to the first battery 12, and the first battery 12 supplies power to the rotating motor 11. The second battery and the servo motor 3, and the first battery 12 and the rotating motor 11 are connected by wires.

The cooperation between the sliding groove and the sliding block further limits the sliding block 15. When the sliding block 15 moves, the sliding block 15 drives the sliding block to move inside the sliding groove, thereby improving the stability of the sliding block 15 when sliding. An annular groove 14 is provided on the inner wall of the rotating hole 13, and an annular slider 17 adapted to the annular groove 14 is fixedly connected to the outer side of the rotating shaft 16. The cooperation between the annular slider 17 and the annular groove 14 rotatably connects the rotating shaft 16 to the inside of the rotating hole 13, thereby limiting the rotation of the rotating shaft 16. When the rotating motor 11 rotates to drive the rotating shaft 16 to rotate, the rotating shaft 16 drives the annular slider 17 to rotate inside the annular groove 14.

[0026] Working principle: when it is necessary to clamp and fix an object with a flat side surface, the two rotating motors 11 are controlled to rotate, so that the two rectangular plates 6 are rotated between the two rotating plates 5, so that the rectangular plates 6 with flat clamping surfaces are used to clamp and fix the object, and the clamping and fixing effect is better. When it is necessary to clamp and fix a cylindrical object, the two rotating motors 11 are controlled to work, and the two clamping plates 7 are rotated between the two rotating plates 5, so that the arc-shaped clamping grooves 8 on the two clamping plates 7 are used to clamp and fix the object, thereby ensuring the clamping and fixing effect of the cylindrical object. The servo motor 3 is controlled to work and drive the bidirectional screw rod 9 to rotate. The rotation of the bidirectional screw rod 9 drives the two sliding blocks 15 to move relative to each other inside the groove 4, thereby driving the two rotating plates 5 to move relative to each other, so that the two rectangular plates 6 or the two clamping plates 7 are used to clamp and fix the object. When the two rectangular plates 6 or the two clamping plates 7 clamp and fix the object, when the pressure value detected by the pressure sensor is greater than the set value, the servo motor 3 is controlled to stop working to avoid excessive pressure from clamping and damaging the object.
