Description

Technical Field

[0001] This utility model relates to the technical field of weighing instrument sensor protection, and in particular to a limit protection device for a large weighing instrument sensor. Background Technology

[0002] Weighing instruments are instruments that measure the mass of objects using Hooke's Law or the lever balance principle of forces. They are a type of measuring device used to weigh objects and are widely used in various sectors of the national economy and in people's daily lives. When using large weighing instruments, sensors are an essential component. They can sense the information being measured and transform the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control. Currently, large weighing instrument sensors often require sensor limit protection devices to protect the weighing instrument sensors and prevent them from tipping over.

[0003] Existing large-scale weighing instrument sensor limit protection devices, such as the one disclosed in patent CN207556665U and the one disclosed in patent CN213021924U, still have certain shortcomings. Both devices are double-sided supports, which makes the device structure unstable during use. When supporting the load, the device is prone to tipping over and cannot effectively prevent the sensor from falling over, thus failing to achieve an effective protection effect. Their limit protection function needs to be improved. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a large weighing instrument sensor limit protection device that can effectively improve the stability of the device structure, avoid tipping, effectively prevent the sensor from falling over, enhance the protection effect, and improve the limit protection function of the sensor.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large weighing instrument sensor limit protection device, comprising a base and a limit protection assembly. The base has mounting holes at all four corners and a lower insertion hole at its top. Two sets of threaded connection holes are provided at the bottom of the lower insertion hole. The limit protection assembly includes a lower limit ring and a cover ring. The lower limit ring is fixedly connected to the top of the base and is coaxial with the lower insertion hole. Four sets of conical limit blocks are fixedly connected in a circular array on the lower limit ring. The bottom of each positioning block is fixedly connected to the top of the base. The top of each of the four sets of conical limiting blocks is provided with a positioning groove, and the bottom of each of the four positioning grooves is provided with a threaded hole. The cover ring is provided with four bolt holes arranged in a ring, and each bolt hole is fitted with an internal hex bolt. The cover ring is installed in the four sets of positioning grooves by the cooperation of the internal hex bolts and the threaded holes, and the top of the cover ring is aligned with the top of the conical limiting block. The inner diameter of the cover ring is the same as that of the lower insertion hole. The bottom of the cover ring is integrally fixedly connected with an upper limiting ring, and the upper limiting ring is the same size as the lower limiting ring.

[0007] Preferably, the four sets of mounting holes on the base and the four sets of bolt holes on the cover ring are all countersunk holes.

[0008] Preferably, a circular rubber pad is fixedly connected to the bottom end of the lower insertion hole, and the circular rubber pad has two through holes.

[0009] Preferably, the bottom of each of the four sets of positioning grooves is fixedly connected with an arc-shaped rubber pad.

[0010] Preferably, all four sets of internal hex bolts are fitted with spring washers.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During use and installation, the base is fixedly installed in an appropriate position by the cooperation of bolts and mounting holes. The bottom of the large weighing instrument sensor is inserted into the lower insertion hole, and the sensor is fixed by the cooperation of bolts and threaded connection holes. After the sensor is installed, four sets of conical limiting blocks surround the sensor. Then, the cover ring is inserted into the positioning groove and fixed by hexagonal bolts, so that the upper limiting ring surrounds the upper side of the sensor. Thus, the sensor is installed from top to bottom into the cover ring, upper limiting ring, conical limiting blocks, lower limiting ring, and lower insertion hole. The upper and lower limiting rings provide limiting protection for the upper and lower ends of the large weighing instrument sensor, respectively. The four sets of conical limiting blocks distributed in a ring array and the cover ring installed on top can support the carrier. Compared with double-sided support, the force is more balanced, which can effectively improve the stability of the device structure, avoid side tipping, effectively prevent the sensor from tilting, enhance the protection effect, and improve the limiting protection function of the sensor.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] Example

[0021] Please see Figures 1-6This utility model discloses a large-scale weighing instrument sensor limit protection device, comprising a base 1, a lower limit ring 5, and a cover ring 8. The base 1 has mounting holes 2 at each of its four corners, and a lower insertion hole 3 at its top. The bottom of the lower insertion hole 3 has two sets of threaded connection holes 4. The lower limit ring 5 is fixedly connected to the top of the base 1, and is coaxial with the lower insertion hole 3. Four sets of conical limit blocks 6 are fixedly connected in a circular array on the lower limit ring 5, and the bottom ends of all four sets of conical limit blocks 6 are fixedly connected to the top of the base 1. Each of the four positioning blocks 6 has a positioning groove 7 at its top, and each of the four positioning grooves 7 has a threaded hole at its bottom. The cover ring 8 has four bolt holes arranged in a ring, each containing a hexagonal socket head cap screw 9. The cover ring 8 is installed in the four positioning grooves 7 by the engagement of the hexagonal socket head cap screws 9 with the threaded holes. The top of the cover ring 8 is aligned with the top of the conical limiting block 6. The inner diameter of the cover ring 8 is the same as the lower insertion hole 3. An upper limit ring 10 is integrally fixedly connected to the bottom of the cover ring 8, and the upper limit ring 10 has the same dimensions as the lower limit ring 5. During installation... The base 1 is fixedly installed in a suitable position by bolts and mounting holes 2. The bottom of the large weighing instrument sensor is inserted into the lower insertion hole 3, and the sensor is fixed by bolts and threaded connection holes 4. After the sensor is installed, four sets of conical limiting blocks 6 surround the sensor. Then, the cover ring 8 is inserted into the positioning groove 7 and fixed by hexagonal socket head cap screws 9, so that the upper limit ring 10 surrounds the upper side of the sensor. Thus, the sensor is installed from top to bottom into the cover ring 8, upper limit ring 10, conical limiting blocks 6, lower limit ring 5 and lower insertion hole 3. The upper limit ring 10 and lower limit ring 5 provide limiting protection for the upper and lower ends of the large weighing instrument sensor, respectively. The four sets of conical limiting blocks 6 distributed in a ring array and the cover ring 8 installed on top can support the carrier. Compared with double-sided support, the force is more balanced, which can effectively improve the stability of the device structure, avoid side tipping, effectively prevent the sensor from tilting, enhance the protection effect, and improve the limiting protection function of the sensor.

[0022] The four sets of mounting holes 2 on the base 1 and the four sets of bolt holes on the cover ring 8 are all countersunk holes. By adopting the countersunk hole structure, the connection strength can be increased during installation, and the mounting surface can be made flatter and more aesthetically pleasing.

[0023] A circular rubber pad 11 is fixedly connected to the bottom of the lower insertion hole 3. The circular rubber pad 11 has two through holes. By setting the circular rubber pad 11, the bottom of the large weighing instrument sensor can be installed more tightly and firmly.

[0024] The bottom of each of the four positioning grooves 7 is fixedly connected with an arc-shaped rubber pad 12; by setting the arc-shaped rubber pad 12, the cover ring 8 can be installed more tightly and securely.

[0025] All four sets of socket head cap screws 9 are fitted with spring washers 13; by setting the spring washers 13, the socket head cap screws 9 can be effectively prevented from loosening after tightening.

[0026] This utility model discloses a large weighing instrument sensor limit protection device. During installation, the base 1 is fixed in a suitable position using bolts and mounting holes 2. The bottom of the large weighing instrument sensor is inserted into the lower insertion hole 3, and the sensor is secured using bolts and threaded connection holes 4. After the sensor is installed, four sets of conical limit blocks 6 surround the sensor. Then, the cover ring 8 is inserted into the positioning groove 7 and secured with hexagonal socket head cap screws 9, so that the upper limit ring 10 surrounds the upper side of the sensor. Thus, the sensor is inserted from top to bottom into the cover ring 8, upper limit ring 10, conical limit blocks 6, lower limit ring 5, and lower insertion hole 3. The upper limit ring 10 and lower limit ring 5 respectively provide limit protection for the upper and lower ends of the large weighing instrument sensor. The four sets of conical limit blocks 6 arranged in a ring array and the cover ring 8 installed on top support the load-bearing body, resulting in a more balanced force distribution compared to double-sided support.

[0027] The present invention relates to a large-scale weighing instrument sensor limit protection device. Its installation method, connection method, or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
