[0041] Truck scales are used to weigh and detect the load of moving vehicles, including mechanical sensors. The mechanical properties of mechanical sensors will be calibrated before leaving the factory. After calibration, the sensors will have corresponding markings on their bodies. When installing and debugging the sensors on the truck scale, the corresponding markings need to be consistent with the load direction of the truck scale to ensure the accuracy of the truck scale weighing. In the relevant prior art, some of the sensors need to be installed while lying on the weighing surface of the truck scale to align the markings, which makes installation and inspection difficult, and there are situations where the installation angle is not in place, affecting the accuracy of the truck scale debugging. Some of them also use auxiliary tooling to install sensors, but the structure of the auxiliary tooling is usually more complicated. For example, the sensor and the auxiliary tooling need to be fixed with multiple screws, and after the sensor is installed on the truck scale, the position of some screws is difficult to see, resulting in a more cumbersome disassembly and assembly process between the sensor and the auxiliary tooling.

[0042] In order to solve the above problems, Figures 1 to 7 As shown, the utility model first provides a sensor installation device, which has a simple structure and is easy to install and can facilitate the alignment of the sensor.

[0043] like Figure 1 to Figure 2 As shown, specifically, the sensor installation device is used to install the sensor 1, the sensor 1 has an identification position 11, the sensor installation device includes a fixed part 2, a movable part 3 and an indicating assembly 5, wherein: one end of the movable part 3 is rotatably connected to one end of the fixed part 2, the other end of the movable part 3 is detachably connected to the other end of the fixed part 2, the movable part 3 can be surrounded by the fixed part 2 to form an installation cavity 4 for accommodating part of the sensor 1; the indicating assembly 5 includes an extension part 51 arranged on a side of the fixed part 2 away from the movable part 3, and is used to indicate the identification position 11.

The sensor installation device has a simple structure, is easy to disassemble and assemble the sensor 1, and is easy to operate.

[0045] When installing the sensor 1 to the truck scale, first install the sensor 1 to the sensor installation device to form the sensor assembly 100, and then install the sensor assembly 100 to the scale body 200 of the truck scale. After the installation is completed, the sensor installation device and the sensor 1 are disassembled; because the identification position 11 of the sensor 1 is aligned with the extension piece 51, it is only necessary to control the extension piece 51 to be consistent with the load direction of the truck scale to ensure that the identification position 11 is consistent with the load direction of the truck scale, so that the user can easily align and check the sensor 1, and the installation accuracy of the sensor 1 is high to ensure the accuracy of the truck scale weighing.

[0046] like Figure 1 and Figure 4 As shown, the indicating assembly 5 further includes a level bubble 52 disposed at one end of the extension member 51 away from the fixing member 2. The level bubble 52 enables the user to more intuitively observe and adjust the sensor installation device and the angle of the sensor 1, avoiding the error caused by visually observing the extension member 51, improving the installation accuracy of the sensor 1, and thus improving the weighing accuracy of the truck scale.

When the second connection component 62 is connected to the first connection component 61 through a thread, the end where the fixed part 2 is detachably connected to the movable part 3 can be pressed and fixed, and there is no need to disassemble and install multiple screws during the installation and disassembly process, and the operation is simple and convenient, thereby improving the efficiency of installing the sensor 1 through the sensor installation device.

[0048] In the illustrated embodiment, the first connecting member 61 is disposed on the movable member 3, and the fixed member 2 is provided with a through hole 21. Since the extension member 51 is facing the user when the sensor 1 is installed, the first connecting member 61 is disposed on the movable member 3 and facing the fixed member 2 and the extension member 51, and the second connecting member 62 is fixed or disassembled with the first connecting member 61 by screw threads on the side of the fixed member 2 close to the extension member 51, so that the user can easily see the first connecting member 61 and the second connecting member 62, and the operation is more convenient. In addition, the first connecting member 61 will not fall off from the movable member 3, thereby preventing the loss of parts.

[0049] The side wall of the through hole 21 may have an opening, and the direction of the opening is consistent with the rotation direction of the movable member 3 relative to the fixed member 2, that is, the direction of the opening is parallel to the rotation plane of the movable member 3, so that when the movable member 3 rotates relative to the fixed member 2, the first connecting member 61 can pass through or escape from the through hole 21. Alternatively, the through hole 21 can also be set as a waist-shaped hole, and the length direction of the waist-shaped hole is consistent with the rotation direction of the movable member 3 relative to the fixed member 2.

The rotating axis of the first connecting member 61 can be parallel to the rotating axis of the movable member 3. The rotatable connection between the first connecting member 61 and the movable member 3 can facilitate the user to disassemble and assemble the second connecting member 62, and avoid interference between the user's hand and the extension member 51 or other components in the vehicle scale when disassembling and assembling the second connecting member 62.

[0051] like Figure 5 As shown, the connecting assembly 6 further includes a first rotating shaft 63, the first rotating shaft 63 includes a first threaded section 631 and a first optical axis section 632 connected to each other, the movable member 3 is provided with a first threaded hole 31, the rotating portion 611 is provided with a first optical hole 6111, the first threaded section 631 can pass through the first optical hole 6111 and is threadedly fastened with the first threaded hole 31, and the rotating portion 611 can rotate relative to the first optical axis section 632 through the first optical hole 6111.

[0052] like Figure 5 As shown, the sensor installation device further includes a first stopper 7 disposed on the movable member 3, and the first stopper 7 can abut against the rotating portion 611 to limit the rotation range of the rotating portion 611 relative to the movable member 3. This prevents the first connecting member 61 from rotating too much, which makes it difficult for the user to control the connection between the first connecting member 61 and the second connecting member 62. At the same time, the first stopper 7 can also ensure the stability of the first connecting member 61 in the through hole 21, and prevent the first connecting member 61 from accidentally falling out of the through hole 21 from the opening of the through hole 21.

[0053] like Figure 5 As shown, the second connecting member 62 includes a nut 621 threadably matched with the threaded portion 612 and a handle 622 extending outward from the outer side wall of the nut 621. The handle 622 can facilitate the user to rotate the nut 621, saving effort and avoiding slipping.

[0054] In another embodiment, the first connecting member 61 may be disposed on the fixed member 2, and the movable member 3 may be provided with a through hole 21. The first connecting member 61 is disposed on the fixed member 2 and faces the movable member 3, and the second connecting member 62 is fixed or disassembled with the first connecting member 61 by threads on the side of the movable member 3 away from the extension member 51.

This prevents the movable member 3 from rotating too much, which makes it difficult for the user to control the connection between the movable member 3 and the detachable end of the fixed member 2.

[0058] In the illustrated embodiment, the second limit member 8 is arranged on the fixed member 2, and can abut against the movable member 3 when the movable member 3 is rotated and opened to a certain range relative to the fixed member 2, so as to limit the movable member 3 from continuing to rotate.
