Description

Technical Field

[0001] The utility model relates to the technical field of drug inspection, in particular to an analytical titration device for drug inspection. Background Art

[0002] A titration apparatus is a device used for chemical analysis. Based on the chemical reaction between the titrant and the sample, the concentration or purity of a specific component in the sample can be determined. It is a commonly used device in the field of pharmaceutical testing.

[0003] When the existing titration device is working, the height of the burette is mostly fixed, which is difficult to adjust according to actual working requirements. In addition, the volume of the titration device is large, which is inconvenient to transport and carry. The burette is also easily broken and damaged by external impact. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an analytical titration device for drug testing.

[0005] The utility model is implemented by the following technical scheme: an analytical titration device for drug inspection, comprising a bearing seat, a transmission shaft is inserted into the interior of the bearing seat, both ends of the transmission shaft are fixedly connected with A main bevel gears, the outer surface of the A main bevel gear is meshed and connected with a telescopic component, and the bottom of the bearing seat is fixedly connected with an outer box;

[0006] The telescopic assembly includes an A secondary bevel gear, which is meshed with an A main bevel gear. A forward and reverse threaded rod is inserted into the interior of the A secondary bevel gear. One end of the forward and reverse threaded rod is rotatably connected to the inner wall of one side of the outer box. Both sides of the forward and reverse threaded rod are threadedly connected to walking blocks, and the outer surface of the walking block is fixedly connected to the scissors frame body.

[0007] Through the above technical solution, the A auxiliary bevel gear and the A main bevel gear are meshed with each other to rotate the positive and negative threaded rods. Since the threads on both sides of the positive and negative threaded rods are opposite, the walking blocks on both sides move relatively, thereby driving the scissor frame to extend and retract, thereby adjusting the height of the burette, so that personnel can adjust the height of the burette in time according to actual work needs.

[0008] As a further improvement of the above solution, a motor housing is fixedly connected to one side of the inner bottom wall of the outer box, a servo motor is fixedly connected to the inside of the motor housing, and a B main bevel gear is fixedly connected to the output end of the servo motor.

[0009] Through the above technical solution, the motor housing can seal and protect the servo motor to avoid the problem of equipment damage caused by the servo motor being exposed to the outside. At the same time, the servo motor starts to drive the B main bevel gear to rotate.

[0010] As a further improvement of the above solution, the outer surface of the B main bevel gear is meshedly connected with a B auxiliary bevel gear, and the B auxiliary bevel gear is sleeved on the middle part of the outer surface of the transmission shaft.

[0011] Through the above technical solution, the servo motor starts to drive the B main bevel gear and the B auxiliary bevel gear to engage and rotate. Since the B auxiliary bevel gear is sleeved on the outer surface of the transmission shaft, the transmission shaft can rotate inside the bearing seat.

[0012] As a further improvement of the above solution, the inner walls on both sides of the outer box are fixedly connected with connecting blocks, and the other ends of the forward and reverse threaded rods are rotatably connected to the surfaces of the connecting blocks through bearings.

[0013] Through the above technical solution, one end of the forward and reverse threaded rod is rotatably connected to the inner wall of the outer box, and the other end is rotated on the surface of the connecting block, which can support the forward and reverse threaded rod to prevent it from moving and falling after being affected by external force.

[0014] As a further improvement of the above solution, a working plate is fixedly connected to the top of the scissors frame, an auxiliary bearing is fixedly connected to the middle of the front side of the working plate, a sleeve is fixedly connected to the inside of the auxiliary bearing via a bearing rod, and a burette is fixedly connected to the inside of the sleeve.

[0015] Through the above technical solution, the burette can be rotated inside the auxiliary bearing through the bearing rod, so that the personnel can rotate the burette conveniently when the device is not in use. Then, by lowering the height of the scissor frame, the burette can be stored inside the outer box, which reduces the space occupation and protects the burette, avoiding the problem that the burette is exposed to the outside and easily broken by impact during transportation.

[0016] As a further improvement of the above solution, both sides of the middle part of the front side of the working plate are fixedly connected to limit blocks, the interior of the limit blocks is plugged with a limit cross bar, and the limit cross bar is plugged into the interior of the bearing rod.

[0017] Through the above technical solution, when the limiting cross bar is inserted into the interior of the bearing rod, the rotation angle of the burette can be fixed, so that the burette will not rotate due to the influence of external force.

[0018] As a further improvement of the above solution, a placement groove is provided on the other side of the inner bottom wall of the outer box, a capacity cup is clamped inside the placement groove, a control panel is provided in the middle of the front of the outer box, and anti-slip pads are fixedly connected to the four corners of the lower surface of the outer box.

[0019] Through the above technical solution, the capacity cup is clamped inside the placement slot, which can prevent the capacity cup from tilting and collapsing during work. At the same time, the start and stop of the servo motor can be controlled through the control panel, making the automated operation more convenient. The anti-slip pad can greatly increase the friction of the device on the ground.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model uses a telescopic component, an A auxiliary bevel gear and an A main bevel gear to mesh with each other to rotate the forward and reverse threaded rods, and the walking blocks on both sides can move relatively, thereby driving the scissor frame to telescope, so as to achieve the effect of adjusting the height of the burette, and when the device is not in use, the personnel can pull out the limit cross bar to rotate the burette, and then by lowering the height of the scissor frame, the burette can be stored inside the outer box, which can not only reduce space occupation, but also protect the burette, and avoid the problem that the burette is exposed to the outside and is easy to be broken by impact during transportation and carrying.

[0032] The telescopic assembly 4 includes an A sub-bevel gear 401, which is meshed with the A main bevel gear 3. A forward and reverse threaded rod 402 is inserted into the interior of the A sub-bevel gear 401, and one end of the forward and reverse threaded rod 402 is rotatably connected to the inner wall of one side of the outer box 5. Both sides of the forward and reverse threaded rod 402 are threadedly connected with walking blocks 403, and the outer surface of the walking block 403 is fixedly connected with a scissors frame 404. The forward and reverse threaded rod 402 is rotated by the mutual meshing of the A sub-bevel gear 401 and the A main bevel gear 3. Since the threads on both sides of the forward and reverse threaded rod 402 are opposite, the walking blocks 403 on both sides move relatively, thereby driving the scissors frame 404 to telescope, thereby adjusting the height of the burette 15, so that personnel can adjust the height of the burette 15 in time according to actual work needs.

[0033] A motor housing 6 is fixedly connected to one side of the inner bottom wall of the outer box 5, a servo motor 7 is fixedly connected to the inside of the motor housing 6, and a B main bevel gear 8 is fixedly connected to the output end of the servo motor 7. The motor housing 6 can seal and protect the servo motor 7 to avoid the problem of equipment damage caused by the servo motor 7 being exposed to the outside. At the same time, the servo motor 7 is started to drive the B main bevel gear 8 to rotate.

[0034] The outer surface of the B main bevel gear 8 is meshedly connected with the B sub-bevel gear 9, and the B sub-bevel gear 9 is sleeved on the middle part of the outer surface of the transmission shaft 2. The servo motor 7 is started to drive the B main bevel gear 8 and the B sub-bevel gear 9 to mesh and rotate. Since the B sub-bevel gear 9 is sleeved on the outer surface of the transmission shaft 2, the transmission shaft 2 can rotate inside the bearing seat 1.

[0035] The inner walls on both sides of the outer box 5 are fixedly connected with connecting blocks 10, and the other end of the forward and reverse threaded rod 402 is rotatably connected to the surface of the connecting block 10 through a bearing. Through the above technical solution, one end of the forward and reverse threaded rod 402 is rotatably connected to the inner wall of the outer box 5, and the other end is rotated on the surface of the connecting block 10, which can support the forward and reverse threaded rod 402 to prevent it from moving and falling after being affected by external force.

[0036] A working plate 11 is fixedly connected to the top of the scissors frame 404, an auxiliary bearing 12 is fixedly connected to the middle of the front of the working plate 11, a sleeve 14 is fixedly connected to the interior of the auxiliary bearing 12 via a bearing rod 13, a burette 15 is fixedly connected to the interior of the sleeve 14, and the burette 15 can be rotated inside the auxiliary bearing 12 via the bearing rod 13, so that it is convenient for personnel to rotate the burette 15 when the device is not in use, and then the height of the scissors frame 404 is lowered so that the burette 15 can be stored inside the outer box 5, which reduces space occupancy and protects the burette 15 to avoid the burette 15 being exposed to the outside and easily broken by impact during transportation.

[0037] Both sides of the middle part of the front side of the working plate 11 are fixedly connected to the limit blocks 16, and the limit cross bar 17 is inserted into the interior of the limit block 16. The limit cross bar 17 is inserted into the interior of the bearing rod 13. When the limit cross bar 17 is inserted into the interior of the bearing rod 13, the rotation angle of the burette 15 can be fixed, so that the burette 15 will not rotate due to external force.

[0038] A placement groove is provided on the other side of the inner bottom wall of the outer box 5, and a capacity cup 18 is clamped inside the placement groove. A control panel 19 is provided in the middle of the front of the outer box 5, and anti-slip pads 20 are fixedly connected to the four corners of the lower surface of the outer box 5. The capacity cup 18 is clamped inside the placement groove to prevent the capacity cup 18 from tilting and collapsing during operation. At the same time, the start and stop of the servo motor 7 can be controlled through the control panel 19, and the automated operation is more convenient. The anti-slip pad 20 can greatly improve the friction of the device on the ground.

[0039] The implementation principle of an analytical titration device for drug inspection in the embodiment of the present application is as follows: a person starts the servo motor 7 through the control panel 19 to drive the B main bevel gear 8 and the B auxiliary bevel gear 9 to engage and rotate. Since the B auxiliary bevel gear 9 is sleeved on the outer surface of the transmission shaft 2, the transmission shaft 2 can rotate inside the bearing seat 1, so that the A auxiliary bevel gear 401 and the A main bevel gear 3 are engaged with each other, so that the positive and negative threaded rod 402 rotates. Since the threads on both sides of the positive and negative threaded rod 402 are opposite, the walking blocks 403 on both sides move relatively, thereby driving The movable scissor frame 404 is extended and retracted to adjust the height of the burette 15, so that the personnel can adjust the height of the burette 15 in time according to actual work needs. When the personnel are not using the device, the burette 15 is rotated, and then the height of the scissor frame 404 is lowered so that the burette 15 and the scissor frame 404 can be stored inside the outer box 5, which reduces the space occupation and protects the burette 15, avoiding the problem that the burette 15 is exposed to the outside and is easily broken by impact during transportation.
