Description

Technical Field

[0001] This utility model relates to a weighing device, and more specifically, to a clamp-type weighing device. Background Technology

[0002] This is a device for detecting leaks in carbon dioxide cylinders of carbon dioxide fire extinguishing controllers for machine tools. Carbon dioxide cylinders may leak during prolonged storage. Previously, it was necessary to remove and weigh the cylinders, which could result in the cylinder's status not being known in real time.

[0003] To obtain real-time information, a weighing device needs to be added to the carbon dioxide machine tool fire extinguishing controller. The carbon dioxide cylinder will be placed on it for real-time weighing. However, the carbon dioxide cylinder may shake during use, causing inaccurate weighing and affecting the weighing accuracy.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a clamp-type weighing device, which, through its structural design, can ensure the stability of carbon dioxide cylinders and guarantee weighing accuracy.

[0006] The technical solution of this utility model is:

[0007] A clamp-type weighing device includes a weighing pan and a sensor electrically connected to the weighing pan. A vertically arranged support frame is fixedly connected to one side of the weighing pan. Several fixed clamp assemblies are arrayed along the length of the support frame facing the weighing pan. Each fixed clamp assembly includes a fixing member fixedly connected to the support frame and extensions at both ends of the fixing member extending toward the outer peripheral wall of a carbon dioxide cylinder. An adjustment part is movably connected to the extension. An opening for cable ties to pass through is provided at the end of the adjustment part away from the extension.

[0008] The present invention is further configured such that the adjusting part is made of an elastic material.

[0009] The present invention is further configured such that the side of the extension away from the support frame is arc-shaped.

[0010] The present invention is further configured such that the extension is provided with a receiving groove for accommodating the adjustment part, and the adjustment part is slidably connected to the inner wall of the receiving groove.

[0011] The present invention is further configured such that the distance from the opening to the adjustment part near the bottom wall of the receiving groove is greater than the length of the receiving groove.

[0012] The present invention is further configured such that the extension is rotatably connected to one end of the fixing member, and the fixing member is provided with a first elastic member, the first elastic member having elastic deformation performance to drive the extensions at both ends of the same fixing member to move closer to each other.

[0013] The present invention is further configured such that a second elastic member is fixedly connected to the inner bottom wall of the receiving groove, and one end of the second elastic member away from the inner bottom wall of the receiving groove is fixedly connected to the adjusting part. The second elastic member has the elastic deformation performance to drive the adjusting part to extend into the receiving groove.

[0014] The beneficial technical effects of this utility model are:

[0015] By setting up a fixed clamp assembly and using cable ties, the carbon dioxide cylinder is securely fixed to the support frame, thus placing it stably on top of the weighing pan and preventing the carbon dioxide cylinder from shaking during equipment operation, which would affect the weighing accuracy.

Detailed Implementation

[0021] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] A clamp-type weighing device, such as Figures 1-4As shown, it includes a weighing pan 1 and a sensor 2 electrically connected to the weighing pan 1. A vertically arranged support frame 3 is fixedly connected to one side of the weighing pan 1. Several fixing clamp components are arrayed along the length of the support frame 3 facing the weighing pan 1. It operates by powering on DC24V. The sensor 2 and the weighing pan 1 are combined and connected to the alarm display device, so that the weight status of the carbon dioxide cylinder can be displayed in real time and accurately.

[0023] The fixing clamp assembly includes a fixing member 4 fixedly connected to the support frame 3. Both ends of the fixing member 4 are provided with extensions 5 extending toward the outer peripheral wall of the carbon dioxide cylinder. The side of the extension 5 away from the support frame 3 is arc-shaped, which has a good guiding effect, making it easier to put the carbon dioxide cylinder between the two extensions 5. An adjustment part 6 is movably connected to the extension 5. The end of the adjustment part 6 away from the extension 5 is provided with a through opening 61 for the cable tie to pass through.

[0024] The extension 5 has a receiving groove 51 for accommodating the adjustment part 6. The adjustment part 6 can extend into or out of the receiving groove 51 to achieve the effect of length adjustment, thereby adapting to carbon dioxide cylinders of different radii. The distance from the opening 61 to the bottom wall of the adjustment part 6 near the inner wall of the receiving groove 51 is greater than the length of the receiving groove 51, so that the opening 61 always extends out of the receiving groove 51 and will not enter the receiving groove 51, making it convenient to use. The adjustment part 6 is made of elastic material, such as aluminum alloy, which has good elastic deformation properties and can deform well, so that it can fit better against the outer peripheral wall of the carbon dioxide cylinder, ensuring the positioning effect and making the placement of the carbon dioxide cylinder more stable. When it is not necessary to fix the carbon dioxide cylinder, the adjustment part 6 returns to its original state through its own elastic deformation properties, so that it can be more easily stored in the receiving groove 51.

[0025] The extension 5 and the fixing member 4 are rotatably connected by a shaft hole. The fixing member 4 is provided with a limiting member 41, which can limit the continuous rotation of the extension 5 and prevent the extensions 5 located at both ends of the fixing member 4 from rotating more than 180°, thereby losing the positioning effect of the clamp. The fixing member 4 is provided with a first elastic member 7, which is a torsion spring. The first elastic member 7 has the elastic deformation performance to drive the extensions 5 at both ends of the same fixing member 4 to move closer to each other. Through the elasticity of the torsion spring, the two extensions 5 can move closer to each other and fit more closely to the carbon dioxide cylinder, ensuring the fixing effect.

[0026] A second elastic element 52 is provided on the inner bottom wall of the receiving groove 51. The second elastic element 52 is a spring. One end of the second elastic element 52 is fixedly connected to the inner bottom wall of the receiving groove 51, and the other end of the second elastic element 52 is fixed to the adjusting part 6. The elasticity of the spring can pull the adjusting part 6 into the receiving groove 51 to complete the storage; it also has the effect of stretching the cable tie, ensuring the fixing effect.

[0027] Working principle: The carbon dioxide cylinder is placed on the weighing pan 1, and the extensions 5 at both ends of the fixing member 4 are moved away from each other. At this time, the first elastic member 7 is deformed by external force. After the carbon dioxide cylinder is moved between the two extensions 5, the first elastic member 7 drives the extensions 5 at both ends of the fixing member 4 to move closer to each other and fit against the outer peripheral wall of the carbon dioxide cylinder through its own elasticity, achieving the effect of initial limiting. The adjusting part 6 is pulled out from the receiving groove 51. At this time, the second elastic member 52 is stretched by external force. Then, the cable tie is passed through the opening 61 of the adjusting part 6 located at both ends of the same fixing member 4 and the cable tie is tightened. At the same time, the second elastic member 52 stretches the adjusting part 6 into the receiving groove 51 through its own elasticity, thereby further making the cable tie fit against the outer peripheral wall of the carbon dioxide cylinder, completing the fixing of the carbon dioxide cylinder and preventing the carbon dioxide cylinder from shaking during the operation of the equipment, which would affect the weighing accuracy. Thus, the weight status of the carbon dioxide cylinder can be displayed in real time and accurately.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
