Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical production technology, and in particular to a clamping device for the safe production of hazardous chemical materials. Background Technology
[0002] In chemical production processes, industrial products are often made into blocks for easy measurement and storage. For example, sodium hydroxide is a hazardous material. Because hazardous chemicals are highly dangerous, they need to be handled by clamping devices to prevent chemical personnel from coming into direct contact with them.
[0003] Existing gripping devices are mostly angled structures, such as tweezers. However, when the chemical product is large, it is often necessary to increase the angle of the tweezers to accommodate the size of the product. When the angle is too large, the tweezers and the chemical product are prone to slipping, making it difficult to grip. Therefore, tweezers-type gripping devices have poor applicability.
[0004] To address the aforementioned issues, we propose a gripping device for the safe production of hazardous materials in the chemical industry. Utility Model Content
[0005] The purpose of this invention is to solve the problems in the background art by proposing a clamping device for the safe production of hazardous materials in the chemical industry.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a clamping device for the safe production of hazardous materials in the chemical industry, comprising a strip plate, a handle fixedly sleeved on the strip plate, a guide groove near the front end of the handle on the strip plate, the guide groove being located on the axis of the strip plate, a slide rail one and a slide rail two fixedly mounted on the lower side wall of the strip plate, the slide rail one and the slide rail two being symmetrically arranged on the front and rear sides of the guide groove, the rear end of the slide rail one being close to the guide groove, and the front end of the slide rail one being away from the guide groove, a movable sleeve one and a movable sleeve two being slidably sleeved on the slide rail one and the slide rail two respectively, a horizontally arranged clamping rod one and a clamping rod two being fixedly connected to the lower wall of the movable sleeve one and the movable sleeve two respectively, and a clamping plate one and a clamping rod two being fixedly mounted at the ends of the clamping rod one and the clamping rod two respectively. Plate 2, the lower side of the strip plate is provided with a slider located below the guide groove. The slider is located behind slide rail 1 and slide rail 2. A vertical moving rod is fixedly inserted on the slider. The moving rod is movably inserted in the guide groove. The moving rod is connected to moving sleeve 1 and moving sleeve 2 by connecting rod 1 and connecting rod 2 respectively. The two ends of connecting rod 1 are rotatably connected to moving sleeve 1 and moving rod respectively. The two ends of connecting rod 2 are rotatably connected to moving sleeve 2 and moving rod respectively. The upper end of the moving rod is fixed with a push handle located on the upper side of the strip plate. The handle has a guide hole located on the lower side of the strip plate. A rod is movably inserted in the guide hole. The front end of the rod extends out of the guide hole and is fixedly connected to the slider. A spring is movably sleeved on the rod between the slider and the handle.
[0007] In the above-mentioned clamping device for the safe production of hazardous materials in the chemical industry, clamping rod one and clamping rod two are arranged in parallel.
[0008] In the above-mentioned clamping device for the safe production of hazardous materials in the chemical industry, vertical support legs are fixed to the middle of the lower walls of clamping rod one and clamping rod two.
[0009] In the aforementioned clamping device for the safe production of hazardous materials in the chemical industry, the rear end of the strip plate has a hanging hole located on the outside of the handle.
[0010] In the above-mentioned clamping device for the safe production of hazardous materials in the chemical industry, gaskets are fixed to the opposite side walls of clamping plate one and clamping plate two.
[0011] In the aforementioned clamping device for the safe production of hazardous materials in the chemical industry, the push handle is made of elastic steel and has multiple anti-slip ribs on its outer wall.
[0012] Compared with existing technologies, the advantages of this gripping device for the safe production of hazardous materials in the chemical industry are:
[0013] This invention uses a push handle to move a movable rod along a guide groove. Under the linkage of connecting rod one and connecting rod two, movable sleeve one and movable sleeve two slide simultaneously along slide rail one and slide rail two, respectively. Since slide rail one and slide rail two are inclined and clamping rod one and clamping rod two are parallel, clamping plate one and clamping plate two can maintain a parallel state when the clamping jaws open or close, reducing the occurrence of slippage when clamping blocky chemical products and providing a certain degree of clamping safety.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figures 1-4A gripping device for the safe production of hazardous materials in the chemical industry includes a strip plate 1, a handle 2 fixedly sleeved on the strip plate 1, a guide groove 3 formed on the strip plate 1 near the front end of the handle 2, the guide groove 3 being located on the axis of the strip plate 1, a slide rail 4 and a slide rail 2 fixedly mounted on the lower side wall of the strip plate 1, the slide rail 4 and the slide rail 2 being symmetrically arranged on the front and rear sides of the guide groove 3, the rear end of the slide rail 4 being close to the guide groove 3, and the front end of the slide rail 4 being away from the guide groove 3, a movable sleeve 5 and a movable sleeve 2 being slidably sleeved on the slide rail 4 and the slide rail 2 respectively, the lower walls of the movable sleeve 5 and the movable sleeve 2 being fixedly connected to horizontal... The clamping rods 6 and 7 are set in parallel. The ends of the clamping rods 6 and 7 are respectively fixed with clamping plates 8 and 9. The opposite side walls of clamping plates 8 and 9 are fixed with gaskets 18. The gaskets 18 are elastic and are used to contact the chemicals. They play a certain flexible clamping role when clamping the chemicals. When the moving sleeves 5 and 2 move simultaneously on the slide rails 4 and 2, the distance between the clamping rods 6 and 7 changes. The clamping rods 6 and 7 remain parallel, so that clamping plates 8 and 9 can open or retract in parallel.
[0021] A slider 10 is located on the lower side of the strip plate 1, below the guide groove 3. The slider 10 is located behind the slide rail 4 and the slide rail 2. A vertical moving rod is fixedly inserted into the slider 10. The moving rod is movably inserted into the guide groove 3. Connecting rod 11 and connecting rod 2 12 are respectively connected between the moving rod and the moving sleeve 5 and the moving sleeve 2. The two ends of connecting rod 11 are rotatably connected to the moving sleeve 5 and the moving rod, respectively. The two ends of connecting rod 2 12 are rotatably connected to the moving sleeve 2 and the moving rod, respectively. A push handle 13 is fixed at the upper end and located on the upper side of the strip plate 1. The push handle 13 is made of elastic steel and has multiple anti-slip ribs on its outer wall. Pushing the push handle 13 causes the moving rod to move along the guide groove 3. Under the linkage of connecting rod 11 and connecting rod 22, moving sleeve 15 and moving sleeve 2 are driven at the same time. When clamping plate 18 and clamping plate 29 hold the chemical product, the elastic push handle 13 has a certain buffering effect, reducing the excessive squeezing of the chemical product by clamping plate 18 and clamping plate 29 when the pushing force is large.
[0022] The handle 2 has a guide hole located on the lower side of the strip plate 1. A rod 14 is movably inserted into the guide hole. The front end of the rod 14 extends out of the guide hole and is fixedly connected to the slider 10. A spring 15 is movably sleeved on the rod 14 between the slider 10 and the handle 2. The spring 15 exerts a pushing force on the slider 10. Under the action of this pushing force, the moving rod is located at the front end of the guide groove 3. The clamping rod 6 and the clamping rod 7 remain parallel and open. When clamping chemical products, push the handle 13 backward to retract the clamping rod 6 and the clamping rod 7 relative to each other to achieve clamping.
[0023] Vertical support legs 16 are fixed to the middle of the lower wall of clamping rod 6 and clamping rod 7. When the clamping device is placed flat, the support legs 16 can lift clamping rod 6 and clamping rod 7, keeping the pads 18 on clamping plates 8 and 9 suspended, reducing contact contamination. The rear end of the strip plate 1 is provided with a hanging hole 17 located on the outside of the handle 2, which facilitates the storage of the clamping device. This device drives the moving rod to move along the guide groove 3 by pushing the push handle 13. Under the linkage of connecting rod 11 and connecting rod 22, moving sleeve 5 and moving sleeve 2 slide along slide rail 4 and slide rail 2 respectively. Since slide rail 4 and slide rail 2 are inclined and clamping rod 6 and clamping rod 7 are parallel, clamping plates 8 and 9 can maintain a parallel state when opening or closing the clamping jaws, reducing the occurrence of slippage when clamping blocky chemical products and providing a certain degree of clamping safety.
[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
