Technical Field

[0001] The utility model relates to the field of weighing sensors, in particular to a cross beam weighing sensor. Background Art

[0002] At present, the existing cross beam weighing sensor lowers the center of gravity of the weighing body and is not easy to fall down. All components are soft-connected, making single-piece replacement, installation, and movement more convenient. However, in actual use, the pressure of heavy objects acts on the ductile body, and the ductile body is subjected to four-way lateral forces for a long time, affecting the service life of the ductile body, thereby reducing the reliability of the weighing sensor. At the same time, there is no overload protection structure. Once the weighing sensor is overloaded, it will be damaged, posing a safety hazard.

[0003] To solve the above problems, the prior art patent (CN202141508U) discloses a cross beam weighing sensor, including an elastic body, a base, and a cable.

Depressions are provided on both sides of each arm of the cross-shaped beam, and strain gauges are attached to the depressions. A bearing member is provided at the center of the upper end surface of the elastic body. The structure of the utility model is simple, convenient for processing and manufacturing, and easy to install. Moreover, the elastic body is a cross-shaped beam perpendicular to each other, and the four walls of the elastic body can be evenly stressed, greatly reducing the influence of four-way lateral forces on the elastic body, and at the same time playing an overload protection role.

[0004] However, in the above prior art, when the elastic body is set and used, the bearing member is easily damaged when being extruded by the bearing member for a long time, reducing the service life of the bearing member. Summary of the Utility Model

[0022] The present utility model provides a cross-beam load cell, which includes a base 101, a connecting mechanism 102, a bearing member 103, a connecting block 104, a shock-absorbing spring 105, an elastic body 106, a first rod 107, a second rod 108, a box body 109, a placement groove 110, a bolt 111 and a block 112. The foregoing solution solves the problem that when the elastic body 106 is used and the bearing member 103 is squeezed for a long time, the bearing member 103 is easily damaged, reducing the service life of the bearing member 103.

[0023] For this specific embodiment, the connecting mechanism 102 is detachably connected to the base 101 and is located at the right end of the base 101.

The connecting block 104 is fixedly connected to the carrier 103 and is located at one end of the carrier 103. A plurality of the telescopic rods are fixedly connected to the connecting block 104 and are evenly arranged at one end of the connecting block 104. Each damping spring 105 is detachably connected to the corresponding telescopic rod and is located at one end of the corresponding telescopic rod. The elastic body 106 is fixedly connected to a plurality of the telescopic rods and is located at the upper ends of the plurality of telescopic rods. Two contact boxes are detachably connected to the connecting block 104 and are symmetrically arranged at one end of the connecting block 104.

The base 101 is connected to the device through the connecting mechanism 102, and then a heavy object is placed on the elastic body 106. The elastic body 106 squeezes the damping spring 105 and simultaneously contracts the telescopic rod. At this time, the elastic body 106 drives the contact block to move downward. When the contact block touches the contact box, the contact block drives the connecting block 104 to move downward through the contact box, and the connecting block 104 drives the carrier 103 to move downward. Buffering is performed through the telescopic rod and the damping spring 105, thereby improving the utilization rate of the elastic body 106 and avoiding wear of the carrier 103.

[0024] Among them, each telescopic rod includes a first rod body 107 and a second rod body 108. The first rod body 107 is fixedly connected to the connecting block 104 and is located at one end of the connecting block 104.

The box body 109 is installed on the connecting block 104, and the placement groove 110 is installed in the box body 109.

[0026] Meanwhile, the contact block includes a bolt 111 and a block 112. The block 112 is fixedly connected to the elastomer 106 and is located at one end of the elastomer 106. One end of the bolt 111 is detachably connected to the block 112, is located at one end of the block 112, and penetrates through the block 112. The other end of the bolt 111 is detachably connected to the elastomer 106 and is located at one end of the elastomer 106. The block 112 is mounted on the elastomer 106 through the bolt 111.

[0027] When using a cross-beam weighing sensor according to this embodiment, during specific use, the base 101 is connected to the device through the connection mechanism 102. Then, a heavy object is placed on the elastomer 106. The elastomer 106 squeezes the shock-absorbing spring 105. At this time, the elastomer 106 drives the second rod 108 to move into the first rod 107. At the same time, the elastomer 106 drives the block 112 to move downward into the placement groove 110 of the box body 109. The block 112 drives the connection block 104 to move through the box body 109, and the connection block 104 drives the bearing member 103 to move. Buffering is performed through the first rod 107, the second rod 108, and the shock-absorbing spring 105, thereby improving the utilization rate of the elastomer 106 and avoiding wear of the bearing member 103.
