Description

Technical Field

[0001] The utility model belongs to the technical field of column type sensors, and in particular relates to a column type sensor limiter. Background Art

[0002] A weighing sensor is a device that converts mass signals into measurable electrical signals. There are many types of weighing sensors. It is very important to choose the correct weighing sensor according to different working environments. In addition, the use and installation methods of different weighing sensors will also affect the service life and measurement accuracy of the weighing sensor.

[0003] Column sensors are functional elements that use metal elastic bodies to convert force into strain. Column sensors are mostly used on truck scales. In the prior art, column sensors on truck scales need to be adjusted and aligned during installation. However, since multiple column sensors need to be aligned at the same time, column sensors often tilt. The load introduction method and positioning limit device requirements for column sensors are relatively stringent. Eccentric loads and lateral loads have a great impact on the weighing accuracy of column sensors.

[0004] At present, the existing column type sensor is easily overturned or even topples over due to impact when in use, which affects the measurement accuracy of the column type sensor. Utility Model Content

[0005] The purpose of the utility model is to provide a column sensor limiter to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a column sensor limiter, comprising a sensor body, a lower limit seat and an upper limit seat, wherein the lower end of the sensor body is fixedly installed in the lower limit seat, the upper end of the sensor body is fixedly installed in the upper limit seat, the four corners of the lower limit seat are fixedly connected with support columns, the upper limit seat is slidably sleeved on the support column, and the upper end of the support column is threadedly connected with a limit nut;

[0007] A bidirectional screw is rotatably installed on one side of the lower limit seat and the upper limit seat, a nut is fixedly connected to one end of the bidirectional screw, two symmetrical positioning blocks are threadedly connected to the bidirectional screw, and arc grooves are opened on the sides of the two positioning blocks close to each other.

[0008] As a preferred embodiment, through holes are provided at the four corners of the upper limit seat, and the support column slides through the through holes.

[0009] As a preferred implementation, a rubber ring is abutted between the limit nut and the upper limit seat, and the rubber ring is sleeved on the support column.

[0010] As a preferred implementation, grooves are provided on the side walls of the lower limit seat and the upper limit seat, and the nuts are located in the grooves.

[0011] As a preferred implementation, guide rods are fixedly mounted on the sides of the lower limit seat and the upper limit seat away from the bidirectional screw, and the positioning block is slidably sleeved on the guide rods.

[0012] As a preferred implementation, a rubber pad is fixedly connected to the inner wall of the arc-shaped groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The column sensor limiter is provided with a lower limit seat, an upper limit seat, a support column and a limit nut. The lower limit seat limits and fixes the lower end of the sensor body, and the upper limit seat limits and fixes the upper end of the sensor body. When the sensor body is impacted, the upper limit seat can slide vertically along the support column, which can play a horizontal limit effect on the column sensor, thereby preventing the column sensor from overturning or even tipping over due to impact, and ensuring the measurement accuracy of the column sensor.

[0015] The column sensor limiter is provided with a bidirectional screw, a nut, a positioning block and an arc groove. When the column sensor is installed, the nut can be rotated to drive the bidirectional screw to rotate, so that the bidirectional screw drives the two positioning blocks to approach each other, so that the arc groove of the positioning block clamps and positions the sensor body, and the operation is convenient.
