Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically a novel column sensor. Background Technology

[0002] The column sensor is one of the commonly used sensors on weighbridges. During the measurement process, gravity acts on the elastic body, causing the elastic body to deform. The deformation is then converted into electronic signals by the strain gauges on the elastic body and transmitted to the display device to display the weight.

[0003] A column-type sensor for weighbridges, disclosed in publication number CN116295765B, relates to the technical field of weighbridge equipment. This column-type sensor includes a base. Two equidistant movable slots are arranged on both sides of the top center of the base. A slider is slidably connected within each movable slot. The top ends of the sliders on the same side are fixedly connected to the front and rear sides of the bottom center of the movable base. A lower ring seat is fixedly connected to the side of the movable base connected to the base. Mounting holes are provided at the front and rear ends of the middle of the side of the movable base away from the base. Mounting seats are fixedly connected to the middle of both sides of the top of the base. Mounting rods are fixedly connected to the front and rear ends of the middle of the adjacent side of the mounting seats. Multiple fixing support structures secure the upper and lower middle parts of the column-type sensor body within the mounting position of the base, ensuring the vertical state of the column-type sensor during use and preventing tilting.

[0004] As we know, the environment in which weighbridges are used is dusty. Dust entering the sensor can affect its accuracy. Existing technologies have not addressed this issue. Therefore, we propose a new type of column sensor. Utility Model Content

[0005] The purpose of this invention is to provide a novel column-type sensor to solve the problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel column-type sensor, comprising a base plate and a sensor body, wherein a balancing base is installed at the top of the base plate, the sensor body is installed on the balancing base, a sensor sealing shell is installed on the outer side of the middle part of the sensor body, a protective outer cover is installed on the base plate outside the sensor body, and the protective outer cover has multiple through holes at equal intervals at the base plate.

[0007] Preferably, a cushioning rubber ring is installed at the contact point between the top of the protective outer casing and the sensor body.

[0008] Preferably, a convex pressure head is installed at the top of the sensor body, and a concave pressure head is installed at the top of the convex pressure head.

[0009] Preferably, the upper part of the convex pressure head is a spherical boss, and the bottom of the concave pressure head is provided with an inner groove that mates with the spherical boss.

[0010] Preferably, the protective outer shell is hexagonal, pentagonal, quadrilateral, or cylindrical in shape.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. A sensor sealing shell is installed on the outer side of the middle part of the sensor body. The sensor sealing shell seals and protects the middle part of the sensor body, reducing the intrusion of dust and other impurities. A protective outer cover is installed on the outside of the base plate, providing overall external protection for the sensor. The sealing shell and the external protection of the protective outer cover doubly prevent dust from entering the sensor, avoiding dust affecting measurement accuracy. The protective outer cover has multiple through holes at equal intervals on the base plate, which can be poured out to drain dust without affecting weighing accuracy.

[0013] 2. A buffer rubber ring is installed at the contact point between the top of the protective outer shell and the sensor body to reduce collision and friction between the protective outer shell and the sensor body, thus playing a buffering and protective role. The buffer rubber ring reduces direct contact damage between components and extends the service life of the sensor.

[0014] 3. The spherical boss of the convex pressure head and the inner groove of the concave pressure head are precisely matched to ensure that the external pressure is stably and evenly transmitted to the sensor body, thereby improving the measurement accuracy. Attached Figure Description

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0029] Please see Figure 1-9In this embodiment of the utility model, a novel column-type sensor includes a base plate 8 and a sensor body 6. The sensor body 6 deforms under the action of gravity to achieve weight detection. A balance base 7 is installed at the top of the base plate 8, and the sensor body 6 is installed on the balance base 7 to ensure that the sensor body is in a balanced state. A sensor sealing shell 5 is installed on the outer side of the middle part of the sensor body 6 to seal and protect the middle part of the sensor body 6 and reduce the intrusion of dust and other impurities. A protective outer cover 4 is installed on the outer side of the base plate 8, which protects the sensor from the outside. A buffer rubber ring 3 is installed at the contact point between the top of the protective outer cover 4 and the sensor body 6 to alleviate the collision and friction between the protective outer cover 4 and the sensor body 6, and play a buffer protection role. The protective outer cover 4 has multiple through holes at equal intervals at the base plate 8, which can be poured out to drain dust without affecting the weighing accuracy.

[0030] The sensor body 6 has a convex pressure head 2 installed at its top, and a concave pressure head 1 installed at its top. The upper part of the convex pressure head 2 is a spherical boss, and the bottom of the concave pressure head 1 is provided with an inner groove that cooperates with the spherical boss. The concave pressure head 1 receives external pressure and transmits it to the convex pressure head 2.
