Description

Technical Field

[0001] This utility model relates to the field of beaker clamping technology, specifically a beaker heating anti-scalding and heat-insulating clamping device. Background Technology

[0002] A beaker is a common laboratory glassware made of glass, plastic, or heat-resistant glass. Beakers are widely used for heating chemical reagents. After heating, to avoid direct contact with the beaker to prevent burns or contamination, beaker tongs are used to hold and transfer the beaker.

[0003] In existing technology, a beaker clamp consists of a pivot and two metal rods. A rubber sleeve is fitted at the front end of the metal rods to facilitate clamping and prevent slippage of the beaker. The ends of the metal rods are bent into an O-shape to form a space for placing fingers, serving as the handle of the beaker clamp for controlling its opening and closing. However, in actual use, the finger space in the handle of the beaker clamp is relatively large. When the beaker clamp is opened, the outer surface of the fingers contacts the handle, but when clamping the beaker, the fingers need to move a considerable distance, which makes it difficult to guarantee the stability of the beaker clamp and easily leads to the beaker clamp slipping out of the hand. Therefore, it is necessary to improve the beaker heating and anti-scalding heat-insulating clamping device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a beaker heating anti-scalding and heat-insulating clamping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a beaker heating anti-scalding and heat-insulating clamping device, including a rotating shaft, a metal rod rotatably mounted on the outside of the rotating shaft, a rubber sleeve sleeved on the outside of the metal rod, a positioning mechanism provided on the outside of the metal rod, and an auxiliary mechanism provided inside the positioning mechanism.

[0006] Preferably, the elastic plastic sleeve is movably installed on the outside of the metal rod, a sponge block is provided on the outside of the elastic plastic sleeve, a threaded sleeve is fixedly installed on the outside of the elastic plastic sleeve, a screw is movably installed inside the elastic plastic sleeve, and a positioning block is fixedly installed on the outside of the metal rod, which facilitates the squeezing of the fingers and thus reduces the risk of the metal rod slipping out of the hand.

[0007] Preferably, the threaded sleeve has a threaded hole at the position corresponding to the screw, and the screw is threaded into the threaded hole to facilitate the limiting operation of the elastic plastic sleeve.

[0008] Preferably, a through groove is provided inside the elastic plastic sleeve at a position corresponding to the positioning block, and the positioning block is slidably installed in the through groove to facilitate the positioning of the elastic plastic sleeve.

[0009] Preferably, the auxiliary mechanism includes a positioning post, which is fixedly installed on the outside of the elastic plastic sleeve. A connecting plate is slidably installed on the outside of the positioning post. A screw is movably installed inside the connecting plate. A support post is fixedly installed at the bottom of the connecting plate. A rubber block is provided at the bottom of the support post. A connecting ear is movably installed on the inner wall of the elastic plastic sleeve. A connecting sleeve is fixedly installed at one end of the connecting ear. An elastic rope is fixedly installed inside the connecting sleeve, which facilitates the support and assisted reset of the metal rod, further reducing the risk of the metal rod slipping out of the hand.

[0010] Preferably, the elastic plastic sleeve has a through hole at the position corresponding to the support column, and the support column is slidably installed in the through hole, which facilitates the lifting and lowering of the support column and makes it convenient to disassemble and assemble the support column.

[0011] Preferably, a through hole is provided inside the connecting ear at a position corresponding to the support column, and the support column passes through the through hole to facilitate the limiting operation of the connecting ear.

[0012] Compared with the prior art, this utility model provides a beaker heating anti-scalding and heat-insulating clamping device, which has the following beneficial effects: 1. This beaker heating anti-scalding and heat-insulating clamping device, through its positioning mechanism, facilitates the initial positioning of the elastic plastic sleeve during use by the positioning block, preventing the elastic plastic sleeve from rotating and making it easy to put the elastic plastic sleeve over the metal rod. The threaded sleeve and screw complete the limiting work of the elastic plastic sleeve. When clamping the heated beaker, the sponge block facilitates the filling of the space around the fingers, thereby facilitating the clamping work and reducing the risk of the metal rod slipping out of the hand. By replacing the sponge block adhered to the surface of the elastic plastic sleeve, it is easy to replace the appropriate size sponge block according to the thickness of the user's fingers.

[0013] 2. This beaker heating and anti-scalding heat-insulating clamping device, through its auxiliary mechanism, uses a positioning post to easily position the connecting plate during use, preventing it from rotating. The screw passing through the connecting plate facilitates its limiting function. The support post and rubber block support the metal rod, preventing it from touching the table and making it easy for the user to pick it up. The support post also helps to limit the connection lugs and facilitates the assembly of the elastic cord. When clamping the beaker, the elasticity of the cord ensures a tight contact between the metal rod and the beaker, further reducing the risk of the metal rod slipping out of the user's hand.

[0016] 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.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Example 1: Please see Figure 1-3This utility model provides a technical solution: a beaker heating anti-scalding and heat-insulating clamping device, including a rotating shaft 1, a metal rod 2 rotatably mounted on the outside of the rotating shaft 1, two metal rods 2 are provided, and the two metal rods 2 are arranged one above the other outside the rotating shaft 1 to facilitate the clamping of the beaker, a rubber sleeve 3 is sleeved on the outside of the metal rod 2, a positioning mechanism 4 is provided on the outside of the metal rod 2, and an auxiliary mechanism 5 is provided inside the positioning mechanism 4.

[0019] Furthermore, the positioning mechanism 4 includes an elastic plastic sleeve 401, which is movably mounted on the outside of the metal rod 2. A sponge block 402 is provided on the outside of the elastic plastic sleeve 401, and the sponge block 402 is glued to the outside of the elastic plastic sleeve 401, thereby facilitating the replacement of the sponge block 402. A threaded sleeve 403 is fixedly mounted on the outside of the elastic plastic sleeve 401, and a screw 404 is movably mounted inside the elastic plastic sleeve 401. A positioning block 405 is fixedly mounted on the outside of the metal rod 2. The positioning block 405 facilitates the initial positioning of the elastic plastic sleeve 401. Positioning prevents the elastic plastic sleeve 401 from rotating, facilitating its placement on the metal rod 2. The threaded sleeve 403 and screw 404 limit the elastic plastic sleeve 401. When clamping the heated beaker, the sponge block 402 fills the space around the fingers, facilitating the clamping operation and reducing the risk of the metal rod 2 slipping out. The sponge block 402, which is attached to the surface of the elastic plastic sleeve 401, can be easily replaced with a sponge block 402 of appropriate size according to the user's finger size.

[0020] Furthermore, the threaded sleeve 403 has a threaded hole at the position corresponding to the screw 404, and the screw 404 is threaded into the threaded hole, which facilitates the limiting work of the elastic plastic sleeve 401 and ensures the stability of the elastic plastic sleeve 401.

[0021] Furthermore, a through groove is provided inside the elastic plastic sleeve 401 at the position corresponding to the positioning block 405, and the positioning block 405 is slidably installed in the through groove, which facilitates the positioning of the elastic plastic sleeve 401 and prevents the elastic plastic sleeve 401 from rotating outside the metal rod 2.

[0022] Please see Figure 4-5Furthermore, in conjunction with Embodiment 1, the auxiliary mechanism 5 includes a positioning post 501, which is fixedly installed on the outside of the elastic plastic sleeve 401. A connecting plate 502 is slidably installed on the outside of the positioning post 501. A screw 404 is movably installed inside the connecting plate 502. A support post 503 is fixedly installed on the bottom of the connecting plate 502. A rubber block 504 is provided at the bottom of the support post 503 and is glued to the bottom of the support post 503. A connecting ear 505 is movably installed on the inner wall of the elastic plastic sleeve 401. A connecting sleeve 506 is fixedly installed at one end of the connecting ear 505. An elastic rope 507 is fixedly installed inside the connecting sleeve 506. The positioning post 501 facilitates the positioning of the connecting plate 502, preventing it from rotating. The screw 404 passes through the connecting plate 502, facilitating its positioning. The support post 503 and rubber block 504 support the metal rod 2, preventing it from touching the table and making it easier for the user to pick it up. The support post 503 also helps to limit the position of the connecting lug 505, facilitating the assembly of the elastic cord 507. When clamping the beaker, the elasticity of the elastic cord 507 ensures close contact between the metal rod 2 and the beaker, further reducing the risk of the metal rod 2 slipping out of the user's hand.

[0023] Furthermore, the elastic plastic sleeve 401 has a through hole at the position corresponding to the support column 503, and the support column 503 is slidably installed in the through hole, which facilitates the lifting and lowering of the support column 503 and makes it convenient to disassemble and assemble the support column 503.

[0024] Furthermore, a through hole is provided inside the connecting ear 505 at the position corresponding to the support post 503, and the support post 503 passes through the through hole to facilitate the limiting operation of the connecting ear 505.

[0025] In actual operation, when this device is used, a sponge block 402 of appropriate size is attached to the surface of the elastic plastic sleeve 401, and the elastic plastic sleeve 401 is placed on the surface of the metal rod 2. With the cooperation of the positioning block 405, the elastic plastic sleeve 401 is initially limited. The connecting ear 505 is slid on the inner wall of the elastic plastic sleeve 401, and the support column 503 is passed through the elastic plastic sleeve 401 and the connecting ear 505, so that the positioning column 501 slides inside the connecting plate 502. The screw 404 is passed through the connecting plate 502 and the elastic plastic sleeve 401. The sleeve 401, in cooperation with the threaded sleeve 403, limits the screw 404, thereby completing the limiting work of the elastic plastic sleeve 401, the connecting plate 502 and the connecting ear 505. The sponge block 402 fills the space around the fingers, reducing the risk of the metal rod 2 slipping out of the hand. As the rubber sleeves 3 move away from each other, the elastic rope 507 is stretched. When clamping the beaker, the elasticity of the elastic rope 507 makes the rubber sleeve 3 in close contact with the beaker, further reducing the risk of the metal rod 2 slipping out of the hand and facilitating the clamping and movement of the beaker.
