It is used to reflect loading capacity, help customers complete weighing operation quickly and at low cost, accurately load and unload, prevent overload and improve work efficiency. It is widely used in bulk cargo loading and unloading operations in factories, mines, railways and ports.

[0003] Traditional loader electronic scale installation facilities are provided with a buffer component, which is mostly realized by using the characteristics of a spring to prevent the electronic scale from being squeezed when the load is quickly loaded, so that the electronic scale is not damaged by a large impact force. However, it should be noted that due to the characteristics of the spring, when the spring deforms rapidly and the deformation amplitude is large, the electronic scale will constantly shake when the spring rebounds, thereby affecting the measurement work of the electronic scale. SUMMARY

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a fixing device of loader electronic scale to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fixing device of loader electronic scale, comprising a base and an installation box arranged above the base, an electronic scale is installed in the installation box, the base and the installation box are vertically slidingly connected, a spring and a sealing membrane are installed between the base and the installation box, a one-way valve and an electromagnetic valve are installed on the base, the one-way valve and the electromagnetic valve are both in communication with the inside of the sealing membrane, and the electronic scale is electrically connected with the electromagnetic valve.

[0007] Preferably, two or more telescopic rods are arranged on the installation box, and the telescopic ends of the telescopic rods are fixedly connected with the top of the base.

[0008] Preferably, a clamping plate is arranged in the installation box, a sliding groove is formed in the side wall of the installation box, a sliding block is slidingly connected in the sliding groove, and one end of the sliding block extending into the installation box is fixedly connected with the clamping plate.

[0009] Preferably, a limiting body is rotatably connected to the other end of the sliding block, a one-way rack is arranged on the side wall of the installation box, and a one-way tooth matched with the one-way rack is arranged on the limiting body.

[0018] The following will be for reference. Figures 1 to 3 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0019] A mounting device for a loader electronic scale, such as Figure 1 and Figure 2 As shown, the system includes a base 1 and a mounting box 2 positioned above the base 1. An electronic scale 3 is installed inside the mounting box 2. The base 1 and the mounting box 2 are vertically slidably connected. The mounting box 2 is equipped with two or more telescopic rods 8, each consisting of a sleeve and an inner rod. The telescopic end of the telescopic rod 8 is fixedly connected to the top of the base 1. The telescopic rods 8 allow the mounting box 2 to move closer to or further away from the base 1. A spring 4 and a sealing membrane 5 are installed between the base 1 and the mounting box 2. When the load compresses the electronic scale 3, the spring 4 is compressed through the cooperation of the spring 4 and the telescopic rods 8, causing the mounting box 2 to move closer to the base 1, thereby preventing the electronic scale 3 from being damaged due to excessive impact.

[0020] The base 1 is provided with a one-way valve 6 and an electromagnetic valve 7, both of which are in communication with the inside of the sealing membrane 5, and the electronic scale 3 is electrically connected with the electromagnetic valve 7.

[0021] It should be noted that when the load is quickly loaded, the spring 4 will rebound after being quickly compressed, which will affect the detection effect of the electronic scale 3, and if the spring 4 is compressed to a large extent, the installation box 2 will even shake constantly with the electronic scale 3, which will greatly affect the progress of the detection work of the electronic scale 3. The device is provided with the sealing membrane 5, the one-way valve 6 and the electromagnetic valve 7, when the installation box 2 moves quickly to the base 1 to compress the spring 4, the air pressure in the inside of the sealing membrane 5 increases, and the high-pressure gas in the inside of the sealing membrane 5 is discharged through the one-way valve 6, that is, the rebound of the spring 4 will cause a negative pressure in the inside of the sealing membrane 5, so that the rebound movement of the spring 4 has a large resistance, so that the spring 4 cannot rebound or rebounds slightly, so as to realize the quick and stable of the electronic scale 3, which is beneficial to the detection work of the electronic scale 3; when the load is unloaded, the electronic scale 3 detects that the weight data is zero (a control system such as a controller is arranged on the electronic scale 3), and the electromagnetic valve 7 is controlled to be opened, so that the external gas flows into the inside of the sealing membrane 5, and the spring 4 rebounds and resets the installation box 2 with the electronic scale 3.

[0022] As shown in Figures 1 to 3 , the installation box 2 is provided with a clamping plate 9, a sliding groove 10 is formed in the side wall of the installation box 2, and a sliding block 11 is slidably connected in the sliding groove 10, one end of the sliding block 11 extending into the installation box 2 is fixedly connected with the clamping plate 9, and the clamping plate 9 can slide along the direction of the sliding groove 10 through the cooperation of the sliding groove 10 and the sliding block 11, so that the position of the clamping plate 9 can be adjusted.

[0023] The other end of the sliding block 11 is rotatably connected with a limiting body 12, and the side wall of the installation box 2 is provided with a one-way rack 13, and the limiting body 12 is provided with a one-way tooth 14 matched with the one-way rack 13, when the one-way rack 13 and the one-way tooth 14 are engaged, the sliding block 11 can only move towards the electronic scale 3.

[0024] As shown in Figure 2 , the side of the clamping plate 9 close to the electronic scale 3 is provided with a soft pad 15, and the friction between the electronic scale 3 and the clamping plate 9 is increased through the arrangement of the soft pad 15, so as to improve the stability of the installation of the electronic scale 3, and the other side of the clamping plate 9 is provided with a handle 16, which is convenient for the user to move the clamping plate 9.

[0025] When the electronic scale 3 is installed, the electronic scale 3 is first placed in the inside of the installation box 2, and then the clamping plate 9 is pushed to move along the direction of the sliding groove 10 and clamps the electronic scale 3, it should be noted that the position of the clamping plate 9 after movement can be limited through the cooperation of the one-way rack 13 and the one-way tooth 14.

[0026] When the electronic scale 3 needs to be removed, the limiting body 12 is lifted upward to disengage the one-way rack 13 from the one-way tooth 14, and then the clamping plate 9 is pulled away from the electronic scale 3 through the handle 16, so that the electronic scale 3 is no longer clamped by the clamping plate 9 and can be taken out.
