[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0019] In order to solve the problem of tipping over when the main body 110 is directly installed on the floor scale in the prior art, the present application sets a support ring 130 at the bottom of the main body 110, and installs the main body 110 and the support ring 130 to form a whole, and uses the support ring 130 to flatten the bottom surface to reduce the possibility of the sensor tipping over.

[0020] In the embodiment of the utility model, Figure 1 The overall structural diagram of the self-limiting weighing sensor is shown; Figure 1 In the invention, the self-limiting weighing sensor comprises a main body 110 and a pressure head 120 installed on the top of the main body 110; in the prior art, the pressure head 120 is directly welded to the main body 110; the pressure head 120 is directly compressed as a pressure surface and sends out an electrical signal to realize detection; and since the sensor needs to bear pressure, but its bottom is an arc-shaped structure, it will tip over when installed on a floor scale.

[0021] In view of the above technical problems, this application proposes a self-limiting weighing sensor. Figure 2 A schematic diagram of the exploded structure of the support ring 130 is shown; Figure 1 and Figure 2In the embodiment, the self-limiting weighing sensor further comprises a support ring 130, the body 110 is located on the support ring 130, a locking hole 131 is provided on the side wall of the support ring 130, and a locking bolt 132 is rotatably installed in the locking hole 131, and the insertion end of the locking bolt 132 abuts against the surface of the body 110; since the support ring 130 and the body 110 can be fixedly installed, and the bottom of the support ring 130 is flat, the support ring 130 can replace the body 110 and be installed on the ground, and the area of ​​the support ring 130 in the horizontal projection can be larger than the body 110, thereby expanding the contact area, making the installation of the body 110 more stable, and at the same time cooperating with the body 110 The height of the main body 110 is changed from the traditional 213mm to the existing 155mm. Without changing the coordination of other components inside the main body 110, the height of the main body 110 is lowered, so that its center of gravity is more stable. A notch 111 corresponding to the locking bolt 132 is opened on the main body 110, and the locking bolt 132 can be inserted into the notch 111 to restrict the main body 110. Since the locking bolt 132 can be inserted into the notch 111, the locking bolt 132 can further prevent the main body 110 and the support ring 130 from rotating relative to each other while contacting the outer wall of the main body 110, thereby ensuring that the main body 110 and the support ring 130 can form a whole after installation.

[0022] Figure 3 Shows a schematic diagram of the exploded structure of a self-limiting weighing sensor; Figure 3In the embodiment, the self-limiting weighing sensor further comprises a fixing frame 140, the fixing frame 140 comprises a base 141 and a supporting bridge 142 guarding the base 141, the supporting bridge 142 has a limiting hole 143, the supporting ring 130 is detachably mounted on the surface of the base 141, the body 110 passes through the limiting hole 143 and is arranged above the base 141, the supporting bridge 142 surrounds the outside of the body 110 to support the body 110; by arranging a fixing frame 140 outside the body 110, on the one hand, the base 141 increases the stability of the sensor after installation, on the other hand, the supporting bridge 142 can limit the upper part of the body 110 to form a support for the body 110, thereby cooperating with the supporting ring 130 to complete the limitation of the position of the body 110 and ensure that the body 110 does not tip over; the limiting hole 143 is a first-order The limiting hole 143 has a ladder structure, and a fastening ring 144 is provided on the step surface of the limiting hole 143, and the inner ring wall of the fastening ring 144 matches the main body 110; the limiting hole 143 is a ladder structure, because after the main body 110 is installed after passing through the limiting hole 143, there is still a gap between the main body 110 and the limiting hole 143, and the main body 110 can still tip over. At this time, a fastening ring 144 is placed on the step surface of the limiting hole 143 to further reduce the movable range of the main body 110, so that the fastening ring 144 and the main body 110 are closely matched, thereby forming a restriction on the main body 110; a pressing ring 145 is detachably installed on the supporting bridge 142, and the pressing ring 145 is sleeved outside the main body 110 and presses the fastening ring 144; the pressing ring 145 is used to press the fastening ring 144 to prevent the fastening ring 144 from moving up and down.

[0023] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
