Detailed implementation manners

[0030] To make the invention purpose, technical solution and beneficial effects of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments.

[0031] As Figures 1 to 4 shown, an adjustable jaw of an automatic sample collector is provided on the automatic sample collector, which includes a support frame 10. A guide rail 11 is provided on the support frame 10, and at least one fixture body 40 that can move on the guide rail 11 is provided on the guide rail 11;

[0032] Each fixture body 40 includes a first mounting plate 62, and the first mounting plate 62 is movably connected to the guide rail 11; a first driving mechanism is provided on the upper surface of the first mounting plate 62, and the first driving mechanism drives the rotation and / or lifting of the first mounting plate 62, and two relatively arranged clamping plates 50 are provided on the lower surface of the first mounting plate 62; a second driving mechanism is provided at one end of the first mounting plate 62, and the second driving mechanism is connected to the two clamping plates 50, and the second driving mechanism drives the two clamping plates 50 to move towards each other or away from each other.

[0033] In the present utility model, by adjusting the rotation angle and height of the fixture body through the first driving mechanism, and at the same time, the two clamping plates 50 of the fixture body 40 can be driven to move towards each other or away from each other through the second driving mechanism, the effects of adjusting the height and rotation angle of the fixture body of the present utility model are achieved, so as to clamp items as needed; and since the distance between the two clamping plates 50 of the fixture body is adjustable, the present utility model can be applied to clamp objects of different sizes, improving the versatility of the present utility model.

[0034] Specifically, first, in the present utility model, the support frame 10 plays a supporting role for other components such as the fixture body 40 of the present utility model. The structure of the support frame 10 is as in the prior art, mainly including support feet 12 and a support frame 10 main body supported by the support feet 12. A guide rail 11 is provided on the support frame 10 main body, and at least one fixture body 40 that can move on the guide rail 11 along the length direction of the guide rail 11 is provided, that is, the effect of moving the fixture body 40 is achieved.

[0035] Secondly, the first driving mechanism drives the rotation and / or lifting of the first mounting plate 62, and two clamping plates 50 are provided on the lower surface of the first mounting plate 62. Under the action of the first driving mechanism, the effect of driving the clamping plates 50 to rotate and / or lift along with the first mounting plate 62 is achieved, that is, the effect of adjusting the rotation angle and height of the fixture body through the first driving mechanism is achieved.

[0036] Furthermore, the second driving mechanism is connected to the two clamping plates 50. Under the action of the second driving mechanism, the second driving mechanism drives the two clamping plates 50 to move towards each other or away from each other. That is, by driving the movement of the two clamping plates 50 through the second driving mechanism, the distance between the two clamping plates 50 is adjusted; by adjusting the distance between the two clamping plates 50, the effect of the two clamping plates 50 clamping an object is achieved. Moreover, since the distance between the two clamping plates 50 of the fixture body is adjustable, the present utility model can be applied to clamping objects of different sizes, improving the versatility of the present utility model.

[0037] In some embodiments of the present utility model, each fixture body 40 further includes a slider 20. The slider 20 can move on the guide rail 11; a telescopic rod 21 is provided below the slider 20. The telescopic rod 21 can extend downward or retract upward, and a first driving mechanism is provided at the bottom of the telescopic rod 21; the first driving mechanism includes a first motor 30. The first main shaft of the first motor 30 is connected to the first mounting plate 62, and the first motor 30 drives the rotation of the first mounting plate 62.

[0038] Specifically, the fixture body 40 includes a slider 20, a telescopic rod 21, the first motor 30 in the first driving mechanism, the first mounting plate 62 and two clamping plates 50 arranged in sequence from top to bottom. The slider 20 drives the telescopic rod 21, the first motor 30, the first mounting plate 62 and the two clamping plates 50 to move along the guide rail 11. A telescopic rod 21 is provided below the slider 20. The lifting effect of the first mounting plate 62, and the first motor 30 and the two clamping plates 50 provided on the first mounting plate 62 is realized through the telescopic rod 21; and through the connection between the main shaft of the first motor 30 and the first mounting plate 62, the effect of the first mounting plate 62 driving the two clamping plates 50 to lift is realized. That is, the effect of adjusting the rotation angle and height of the fixture body through the first driving mechanism is realized. In the present utility model, it is mainly used to clamp a sample bottle, and the angle and height of the two clamping plates 50 clamping an object can be adjusted, improving the versatility of the present utility model for clamping objects of different specifications and sizes.

[0039] In some embodiments of the present utility model, a chute 41 is provided below the first mounting plate 62; the second driving mechanism includes a second motor 42 and a rotating rod 43 connected to the second motor 42. The rotating rod 43 is arranged in the chute 41; connection threads 44 with opposite rotation directions are respectively provided at both ends of the rotating rod 43. Threaded connecting plates 45 meshing with the connection threads 44 are provided on the upper parts of the two clamping plates 50. The threaded connecting plates 45 are detachably connected to the clamping plates 50; when the rotating rod rotates, the threaded connecting plates 45 move on the connection threads 44, and the two clamping plates 50 move towards each other or away from each other.

[0040] Specifically, since the second motor 42 is connected to the rotating rod 43, and the rotating rod 43 is rotatably connected to the sliding groove 41, and the rotating rod 43 can rotate within the sliding groove 41, the second motor 42 can drive the rotating rod 43 to rotate. Also, since the two threaded connecting plates 45 are respectively meshed and connected with the two connecting threads 44, and the rotation directions of the two connecting threads 44 are opposite, when the rotating rod 43 rotates, it can drive the two connecting plates to move towards each other or away from each other; that is, under the action of the second driving mechanism, the opposite movement or the back-and-forth movement of the two clamping plates 50 is realized. That is, under the action of the second driving mechanism, the distance between the two clamping plates 50 is adjusted, and then the effect of clamping items of different specifications and sizes is realized, improving the versatility of the present utility model for clamping items of different specifications and sizes.

[0041] In some embodiments of the present utility model, a clamping plate 50 replacement structure is provided on the threaded connecting plate 45. The clamping plate 50 replacement structure includes a plug-in groove 51; a plug-in groove 51 is opened at the lower part of the threaded connecting plate 45, and a plug-in block 52 is provided at the upper part of the clamping plate 50; a first threaded hole 53 is opened on the side groove wall of the plug-in groove 51, a second threaded hole 54 is opened on the plug-in block 52, and the positions of the first threaded hole 53 and the second threaded hole 54 are adapted to each other. The plug-in block 52 is detachably fixed in the plug-in groove 51 by inserting a first screw 55 into the first threaded hole 53 and the second threaded hole 54.

[0042] In the present utility model, for the convenience of using the present utility model, the fixture main body in the present utility model is replaceable. When replacing, the plug-in block 52 can be inserted into the plug-in groove 51. And since both the first threaded hole 53 and the second threaded hole 54 are meshed and connected with the screw 55, the disassembly effect of the clamping plate 50 relative to the threaded connecting plate 45 can be realized by the meshing of the screw 55 with the first threaded hole 53 and the second threaded hole 54 respectively, so as to realize the replaceable effect of the clamping plate 50, ensuring the service life of the present utility model.

[0043] Furthermore, the clamping plate 50 replacement structure further includes a limiting mechanism 60; the limiting mechanism 60 includes a second mounting plate 62, and two limiting plates 64 are arranged on the inner side of the second mounting plate 62; a connecting hole 63 is further opened on the outer wall of the plug-in groove 51, the connecting hole 63 is perpendicular to the direction of the first threaded hole 53, and the limiting plate 64 is correspondingly inserted into the connecting hole 63.

[0044] Specifically, after the limiting plate 64 is correspondingly inserted into the connecting hole 63, the situation that the screw 55 loosens due to the vibration generated during operation can be prevented, that is, the connection effect between the threaded connecting plate 45 and the mounting plate 62 is strengthened, and the situation that the threaded connecting plate 45 and the mounting plate 62 are separated from the clamping plate 50 is avoided. Moreover, by replacing the clamping plates 50 of different specifications, it is convenient for the device to be applicable to more specifications and styles of sample bottles, increasing the versatility of the clamping jaws.

[0045] Furthermore, the limiting mechanism 60 further includes a main rod 61. The main rod 61 is disposed on the second mounting plate 62, and a spring 65 is sleeved on the main rod 61. Two ends of the spring 65 respectively abut against the main rod 61 and the connecting plate.

[0046] Specifically, since the spring 65 is sleeved on the main rod 61 and two ends of the spring 65 respectively abut against the main rod 61 and the mounting plate 62, the elastic force of the spring 65 can limit the main rod 61 to prevent the main rod 61 from loosening and ensure the fixing effect of the mounting plate 62.

[0047] In some embodiments of the present invention, a pull ring 70 is further disposed on the outer side of the second mounting plate 62. The pull ring 70 can facilitate pulling the main rod 61 when disassembling the clamping plate 50, thereby increasing the convenience of operation.

[0048] In some embodiments of the present invention, an anti-slip pad 80 is disposed on the side surface of the clamping plate 50. The anti-slip pad 80 can increase the friction between the clamping plate 50 and an article, make the fixture body more firm when clamping a sample bottle, and avoid the situation that the sample bottle slides.

[0049] As an embodiment of the present invention, a plurality of fixture bodies can be disposed on the guide rail 11 to improve the working efficiency.

[0050] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
