Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-temperature constant-temperature reaction bath technology, specifically a low-temperature constant-temperature reaction bath. Background Technology
[0002] Low-temperature constant-temperature reaction baths are suitable for low-temperature experiments in scientific research, biology, physics, medicine, chemical industry and other departments. They can replace dry ice and liquid nitrogen for low-temperature reactions and provide low-temperature conditions for related equipment. They can also be used as low-temperature water tanks for viscosity testing. Additionally, they can be equipped with magnetic stirrers at the bottom for two-stage stirring, making the temperature inside the stainless steel tank more uniform and providing precise intelligent temperature control.
[0003] However, when existing low-temperature constant-temperature reaction baths are put into use, the material is placed in a beaker and then the beaker is moved into the water tank for testing. However, after the test is completed, the staff needs to remove the beaker. Under the mixture of room temperature and cold temperature, some water droplets and liquid residue will remain on the surface of the beaker. Moreover, the temperature of the beaker is low, which not only makes it inconvenient for the staff to pick up the beaker, but also easily causes water droplets to fall onto the top of the workbench.
[0004] Meanwhile, in most low-temperature constant-temperature reaction baths, the position of the beaker is adjusted by the staff using bolts. After the material in the beaker has been tested, the staff needs to take out the beaker, clamp the beaker with the prepared material, and then move the beaker to the low-temperature water bath. The process is quite cumbersome, which reduces the staff's testing speed. Utility Model Content
[0005] The purpose of this invention is to provide a low-temperature constant-temperature reaction bath to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature constant-temperature reaction bath, including a controller and a worktable bolted to the top of the controller, and further comprising:
[0007] A rotating rod is rotatably connected to the top of the workbench. A limit mechanism is provided on one side of the rotating rod. A sleeve is rotatably connected to the surface of the rotating rod. A connecting rod is bolted to one side of the sleeve. A clamping assembly is provided on one side of the connecting rod.
[0008] A fixed housing is bolted to the top of the workbench. A manual disc is provided on one side of the fixed housing. A spur gear is fixed to one side of the manual disc. A first rack plate is meshed on one side of the spur gear.
[0009] A second rack plate meshes with the other side of the spur gear. A moving rod is bolted to one side of the second rack plate, and a sponge block is bolted to one side of the moving rod. A guide mechanism is provided on one side of the sponge block.

[0012] Preferably, the number of connecting rods is three, and they are arranged in a circular array around the central axis of the casing.
[0013] Preferably, the first rack plate and the second rack plate are the same size and are designed symmetrically about the central axis of the spur gear.
[0014] Preferably, the cross-sectional shape of the limiting block is an equilateral triangle, and the shape of the limiting block corresponds to the inner wall shape of the corresponding groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention, through the cooperation of a manual disc, spur gear, first rack plate, and second rack plate, allows the moving rods on both sides to drive the sponge block to move in opposite directions. This enables the sponge block to clean the surface of the beaker after testing, effectively reducing water droplet residue on the beaker surface, making it easier for staff to pick up the beaker, and reducing the occurrence of water droplets falling onto the top of the workbench. At the same time, with the cooperation of the limiting mechanism, the housing, and the connecting rod, staff can pre-fix the beaker with the prepared materials using the clamping assembly, thereby speeding up the testing process.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4As shown, a low-temperature constant-temperature reaction bath includes a controller 1, which enables the low-temperature constant-temperature reaction bath to operate. A worktable 2 is bolted to the top of the controller 1. A rotating rod 3 is rotatably connected to the top of the worktable 2 via a bearing seat. A limit mechanism 4 is provided on one side of the rotating rod 3. A housing 5 is rotatably connected to the surface of the rotating rod 3. With the cooperation of the rotating rod 3 and the limit mechanism 4, the housing 5 can be limited, which facilitates the adjustment of the position of the housing 5 by the operator and reduces the workload of the operator. A connecting rod 6 is bolted to one side of the housing 5. There are three connecting rods 6 arranged in a circular array around the central axis of the housing 5. A clamping assembly 7 is provided, which clamps the beaker by driving a clamping block through a rotating bidirectional threaded rod, allowing the beaker to react on top of the controller 1. Under the action of the housing 5, the connecting rod 6 can drive the clamping assembly 7 to rotate around the central axis of the rotating rod 3. With the combined effect of the connecting rod 6 and the clamping assembly 7, the operator can clamp the material to be tested in advance, speeding up the material testing process. A fixed housing 8 is bolted to the top of the workbench 2. A manual disc 9 is provided on one side of the fixed housing 8. A spur gear 10 is fixed to one side of the manual disc 9. The bottom of the spur gear 10 is connected to the inner cavity of the fixed housing 8. The rotating connection, in cooperation with the manual disc 9 and the fixed housing 8, allows the spur gear 10 to rotate. One side of the spur gear 10 meshes with a first rack plate 11, and the other side meshes with a second rack plate 12. The first rack plate 11 and the second rack plate 12 are of the same size and are symmetrically designed about the central axis of the spur gear 10. A moving rod 13 is bolted to one side of the second rack plate 12, and the surface of the moving rod 13 is slidably connected to the inner cavity of the fixed housing 8. Another moving rod 13 is bolted to one side of the first rack plate 11. Under the action of the spur gear 10, the first rack plate 11 and the second rack plate 12 can simultaneously drive the moving rods 13 on both sides. Moving in the opposite direction, a sponge block 14 is attached to one side of the moving rod 13. Under the action of the moving rod 13, the sponge blocks 14 on both sides can be moved, allowing the sponge blocks 14 to clean the coolant on the surface of the beaker, making it easier for the staff to pick up the beaker and reducing the amount of coolant dripping onto the top of the workbench 2, thereby increasing the practicality of the low-temperature constant-temperature reaction bath. A guide mechanism 15 is provided on one side of the sponge block 14. Under the action of the guide mechanism 15, the position of the sponge block 14 can be effectively prevented from shifting during operation, increasing the stability of the sponge block 14, thereby increasing the stability of the low-temperature constant-temperature reaction bath.
[0024] The limiting mechanism 4 includes a blocking block 41, the bottom of which is bolted to the top of the rotating rod 3. Under the action of the blocking block 41, the housing 5 can be effectively prevented from detaching from the surface of the rotating rod 3. A limiting block 42 is bolted to the surface of the rotating rod 3. A corresponding groove 43 is provided at the bottom of the housing 5. The cross-sectional shape of the limiting block 42 is an equilateral triangle. The shape of the limiting block 42 corresponds to the inner wall shape of the corresponding groove 43. Under the action of the housing 5 moving, the connecting rod 6 can move the beaker out of the controller 1 through the clamping assembly 7. With the cooperation of the limiting block 42 and the corresponding groove 43, the angle of the clamping assembly 7 moving the beaker can be more accurate, so that the beaker can be in the center, which makes it convenient for the staff to adjust the position of the beaker and reduces the workload of the staff.
[0025] The guiding mechanism 15 includes a mounting rod 151, one side of which is bolted to one side of the sponge block 14. A guide block 152 is bolted to one side of the mounting rod 151. A groove 153 is provided on the top of the worktable 2. The surface of the guide block 152 is slidably connected to the inner cavity of the groove 153. With the cooperation of the first rack plate 11 and the second rack plate 12, the sponge block 14 can move the guide block 152 in the inner cavity of the groove 153 through the mounting rod 151. With the cooperation of the shapes of the guide block 152 and the groove 153, the position of the sponge block 14 is effectively prevented from shifting during movement, thus increasing the stability of the sponge block 14 and thereby increasing the stability of the low-temperature constant temperature reaction bath.
[0026] Working principle: First, the operator pours the material to be tested into the beaker. When the beaker needs to be clamped by the clamping component 7, the connecting rod 6 moves the clamping component 7 upward through the sleeve 5, thus clamping the beaker. When the material in the beaker needs to be tested, the sleeve 5 moves downward so that the limiting block 42 aligns with the corresponding groove 43, ensuring that the beaker fixed by the clamping component 7 is in the center of the controller 1. Then, the controller 1 is turned on for testing. Simultaneously, the operator adds the material to be tested later and fixes it using other clamping components 7. After the test is completed, the operator... The operator manually rotates the spur gear 10 using the manual dial 9. The spur gear 10 drives the first rack plate 11 and the second rack plate 12 to move in opposite directions simultaneously. This causes the moving rods 13 on both sides to move the sponge block 14 inward. With the cooperation of the guide mechanism 15, the movement of the sponge block 14 can be made more stable. Then, the operator uses the sleeve 5 to move the clamping assembly 7 to move the beaker upward, allowing the sponge block 14 to wipe the beaker. The operator rotates the sleeve 5 to rotate the prepared beaker on the other side to the center of the controller 1. Then, the above steps are repeated to test the prepared beaker containing the material.
