Description

Technical Field

[0001] This utility model relates to the field of experimental apparatus technology, and more specifically, to a beaker clamp that is easy to use. Background Technology

[0002] In industrial production, it is often necessary to conduct laboratory tests on various products or samples to determine whether their parameters meet the factory requirements. Laboratory equipment, instruments, and clamps used in conjunction with glassware assist in chemical analysis. When glassware containing hot solutions needs to be transferred or used, high demands are often placed on the clamping tools used, which must meet the requirements of safety, convenience, and robustness. Currently, beaker clamps are commonly used.

[0003] Existing beaker clamps are similar to clamping tools such as fire tongs, but beaker clamps are shorter overall and have a wide, flat clamping shape, which can hold beakers more stably. When actually holding beakers, the wrist joint must be kept horizontal to hold the beaker horizontally. However, a horizontal wrist joint is not easy to lift heavy objects. When it is necessary to hold the beaker in front, the horizontal wrist joint needs to be bent at a certain angle. This is especially difficult when there is a lot of liquid in the beaker, and it is easy to lose strength and cause the beaker to fall. Moreover, long-term use can easily cause wrist joint damage. Therefore, this utility model provides a beaker clamp that is easy to use. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a beaker clamp that is easy to use, which solves the problems that the existing beaker clamp is relatively difficult to use, and is prone to loss of strength, resulting in unstable clamping and the beaker falling. Moreover, long-term use can easily cause wrist joint damage.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A user-friendly beaker clamp includes a mounting bracket, one end of which is fixedly connected to a pin, a pair of collars are rotatably connected to the outer circumference of the pin, a handle and a connecting rod are fixedly connected to the outer circumference of the collars, a spring is fixedly connected between the handles, and a clamping nozzle is fixedly connected to one end of the connecting rod.

[0009] A handle is fixedly connected to one end of the mounting bracket away from the pin. A pair of connecting blocks are fixedly connected to the outer circumference of the handle. Each pair of connecting blocks has a through groove. A rectangular operating rod passes through the through groove. The rectangular operating rod is movably connected to the connecting block through the through groove. A connecting frame is fixedly connected to the upper end of the rectangular operating rod. A pair of small rollers are rotatably connected to the upper end of the connecting frame. The pair of small rollers are clamped on both sides of the handle.

[0010] Furthermore, a protective block is fixedly connected inside the clamp, and the protective block is made of rubber material.

[0011] Furthermore, a flexible layer is fixedly connected to the surface of the rectangular operating rod.

[0012] Furthermore, a pair of limiting blocks are fixedly connected to the rectangular operating rod, and the pair of limiting blocks are clamped between a pair of connecting blocks.

[0013] Furthermore, the clamp is in contact with the outer circumferential surface of the small roller shaft in the initial state.

[0014] 3. Beneficial Effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this solution, the palm of the operator's hand contacts the handle, and the four fingers rest on the rectangular operating rod to control the entire beaker clamp. When it is necessary to clamp the beaker, move it to the mouth of the beaker, place the two clamping mouths on the two sides of the beaker, and then tighten the four fingers. The four fingers will drive the rectangular operating rod to move closer to the handle. During the process of moving closer, the rectangular operating rod, together with the connecting frame, will drive the small roller to move synchronously. The synchronously moving small roller will gradually gather the clamp handle, so that the clamping mouth can tightly clamp the beaker. During the entire clamping process, the wrist joint of the operator's hand is vertical and the wrist joint does not need to bend at an angle, which makes it convenient for the operator to exert force for a long time and can effectively reduce the possibility of the beaker falling due to lack of strength.

[0017] (2) When the wrist joint of the person's hand is in a vertical position, the person can grasp the beaker in front without bending the angle. The operation is more scientific and can effectively reduce the possibility of strain on the wrist joint of the person's hand. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example

[0025] like Figure 1-3 As shown, a beaker clamp that is easy to use includes a mounting frame 1. One end of the mounting frame 1 is fixedly connected to a pin 2. A pair of collars 3 are rotatably connected to the outer circumference of the pin 2. A clamp handle 4 and a connecting rod 5 are fixedly connected to the outer circumference of the collars 3. A spring piece 401 is fixedly connected between the clamp handles 4. A clamping nozzle 6 is fixedly connected to one end of the connecting rod 5.

[0026] A handle 7 is fixedly connected to the end of the mounting bracket 1 away from the pin 2. A pair of connecting blocks 8 are fixedly connected to the outer circumference of the handle 7. Each pair of connecting blocks 8 has a through groove 801. A rectangular operating rod 9 passes through the through groove 801. The rectangular operating rod 9 is movably connected to the connecting block 8 through the through groove 801. A connecting frame 10 is fixedly connected to the upper end of the rectangular operating rod 9. A pair of small rollers 11 are rotatably connected to the upper end of the connecting frame 10. The pair of small rollers 11 are clamped on both sides of the clamp handle 4.

[0027] In use, the user places their palm (tiger's mouth) in contact with the handle 7, with four fingers resting on the rectangular operating lever 9 to control the beaker clamp. When the beaker needs to be clamped, it is moved to the mouth of the beaker, with a pair of clamping tips 6 placed on either side of the beaker. Then, the user tightens their four fingers, which will move the rectangular operating lever 9 toward the handle 7. During this movement, the rectangular operating lever 9, in conjunction with the connecting frame 10, will move the small roller 11 synchronously. The synchronously moving small roller 11 will gradually converge the clamp handle 4, allowing the clamping tips 6 to firmly hold the beaker. Throughout the clamping process, the user's wrist joint remains vertical, without the need for bending, allowing for sustained exertion of force and effectively reducing the possibility of the beaker falling due to fatigue.

[0028] It should be noted that the specific shape of the clamping spout 6 can be adjusted according to the beaker to be clamped. Figure 1Based on the above, adaptive modifications were made to match beakers of different sizes.

[0029] like Figure 1 As shown, a protective block 601 is fixedly connected inside the clamp 6, and the protective block 601 is made of rubber material.

[0030] When in use, the protective block 601 made of rubber material can reduce the rigid squeezing force between the clamp 6 and the beaker to prevent damage to the beaker, and can also increase the friction between the clamp 6 and the beaker to improve the stability of clamping.

[0031] like Figure 1 and Figure 3 As shown, a flexible layer 902 is fixedly connected to the surface of the rectangular operating rod 9.

[0032] When in use, the rectangular operating lever 9 can match the through groove 801, ensuring that the rectangular operating lever 9 can only move horizontally on the connecting block 8. If the rectangular operating lever 9 is cylindrical, it may rotate during operation, resulting in unstable operation. The flexible layer 902 can eliminate the sharp edges of the rectangular operating lever 9 and improve the comfort of operation.

[0033] like Figure 1 and Figure 3 As shown, a pair of limiting blocks 901 are fixedly connected to the rectangular operating lever 9, and the pair of limiting blocks 901 are clamped between a pair of connecting blocks 8.

[0034] When in use, the limit block 901 can limit the rectangular operating rod 9, preventing the rectangular operating rod 9 from moving up and down a large range on the connecting block 8, thereby further improving the stability of operation.

[0035] like Figure 1 As shown, the clamp 4 is in contact with the outer circumferential surface of the small roller shaft 11 in the initial state.

[0036] In use, since a pair of small rollers 11 clamp the handle 4 in the initial state, thus limiting the handle 4, the beaker clamp as a whole will not be able to rotate or deviate on the mounting frame 1, ensuring stable operation.

[0037] In summary, the specific working process of this solution is as follows: The operator's palm contacts the handle 7 with the web of their hand, and four fingers rest on the rectangular operating rod 9 to control the entire beaker clamp. When it is necessary to clamp the beaker, the operator moves it to the mouth of the beaker, and a pair of clamping mouthpieces 6 are placed on both sides of the beaker. Then, the operator tightens their four fingers, which will drive the rectangular operating rod 9 to move closer to the handle 7. During the closing process, the rectangular operating rod 9, together with the connecting frame 10, will drive the small roller shaft 11 to move synchronously. The synchronously moving small roller shaft 11 will gradually converge the clamping handle 4, so that the clamping mouthpieces 6 can firmly clamp the beaker. During the entire clamping process, the operator's wrist joint is in a vertical position, and the wrist joint does not need to bend at an angle, which makes it convenient for the operator to exert force for a long time and can effectively reduce the possibility of the beaker falling due to lack of strength. After use, the operator releases the rectangular operating rod 9, and the clamping handle 4 will return to its initial state under the push of the spring piece 401.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
