Description

Technical Field

[0001] This utility model belongs to the technical field of liquid level transmitters, and specifically relates to a protective buffer structure for a liquid level transmitter. Background Technology

[0002] Utility model patent CN221725339U discloses a protective buffer structure for a level transmitter, including a mounting plate. A level transmitter body is fixedly fixed through the center of the mounting plate. A protective frame is fixedly installed on the outside of the level transmitter body. Side guard plates are elastically connected to the periphery of the protective frame via springs. A top guard plate is elastically connected to the top of the level transmitter body via springs. Connecting posts are fixed at the four corners of the inner sidewalls of the side guard plates and the four corners of the bottom of the top guard plate. This utility model, by setting a protective frame on the outside of the level transmitter body and elastically setting side guard plates and a top guard plate on the outside of the protective frame, can block forces from the periphery of the level transmitter body through the four side guard plates and block forces from above the level transmitter body through the top guard plate, thereby achieving buffer protection for the level transmitter body.

[0003] However, the above-mentioned mechanism has the following problems: the most common connection method for existing level transmitters is to connect them with flange bolts, while the level transmitter in the above structure obviously needs to be improved in terms of overall shape design. This method greatly increases the cost of the level transmitter and reduces the applicability of the device. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a protective buffer structure for a level transmitter, thereby solving the problem that existing level transmitters require improvements to their overall shape design when providing buffer protection functions, which increases the cost of the level transmitter and reduces its applicability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a level transmitter protection buffer structure, comprising a buffer frame, wherein the buffer frame includes multiple buffer plates, each buffer plate includes a buffer rod, and the upper and lower ends of the buffer rod are respectively connected to a crossbar and a sleeve. The sleeve is bolted to the flange of the level transmitter body. The multiple buffer plates are interconnected by a lower connector, the lower connector including a connecting rod one and a connecting rod two. One end of the connecting rod one and the connecting rod two is rotatably connected to the sleeve by a pin, and the other end of the connecting rod one and the connecting rod two is respectively provided with a pin and a snap-fit ​​groove. The pin is adapted to the snap-fit ​​groove. The end of the crossbar is connected to an external threaded plate, and the external threaded plate is threadedly connected to an upper connector.

[0006] The beneficial effects of this utility model are as follows: the buffer plate can be connected to the liquid level transmitter body using the bolts used to install the liquid level transmitter body itself, without the need to make any changes to the appearance of the liquid level transmitter body, which effectively improves the applicability of the device; multiple buffer plates can be quickly and stably assembled into a whole by connecting the lower connector and the upper connector, providing reliable buffer protection for the liquid level transmitter body.

[0007] To ensure a stable connection between one end of the buffer plate using the lower connector;

[0008] As a further improvement to the above technical solution: the snap-fit ​​groove and the pin are staggered vertically, and the width of the opening end of the snap-fit ​​groove is not greater than the diameter of the pin.

[0009] The beneficial effect of this improvement is that, after unfolding, the staggered snap-fit ​​grooves and pins can stably connect multiple buffer plates into one unit by connecting the snap-fit ​​grooves and pins on adjacent buffer plates.

[0010] In order to achieve effective cushioning and protection through the use of a buffer plate;

[0011] As a further improvement to the above technical solution: the buffer rod is an elastic arc-shaped rod structure.

[0012] The beneficial effect of this improvement is that the buffer rod undergoes elastic deformation when subjected to pressure from external objects, thus providing effective buffering and protection in both the radial and axial directions.

[0013] To ensure a stable connection at the top of multiple buffer plates;

[0014] As a further improvement to the above technical solution: the external threaded plate is an arc-shaped plate structure, and when multiple buffer plates are connected into a whole by a lower connector, the axes of the multiple external threaded plates are collinear, and the upper connector includes an internal threaded tube, which is threadedly connected to the external threaded plate.

[0015] The beneficial effect of this improvement is that after the buffer plate is securely installed on the level transmitter body, the upper connector can be screwed onto the external thread plate to stably connect multiple buffer plates into one unit.

[0016] To further improve the stability of the connection between multiple buffer plates;

[0017] As a further improvement to the above technical solution: a limiting rod is formed on the inner end face of the internally threaded tube, and the curved side of the limiting rod is slidably connected to the inner wall of the externally threaded plate.

[0018] The beneficial effects of this improvement are: the limiting rod plays a limiting role, effectively supports the buffer plate on the inner side of the external thread plate, and ensures the stability of the connection between multiple buffer plates.

[0019] In order to effectively buffer and protect the level transmitter body in the axial direction;

[0020] As a further improvement to the above technical solution: the distance between the crossbar and the top of the liquid level transmitter body is not less than one centimeter.

[0021] The beneficial effect of this improvement is that by maintaining a suitable initial distance between the crossbar and the level transmitter body, an effective movement space can be provided for the crossbar when it is subjected to pressure that causes the buffer rod to deform.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0029] Example 1:

[0030] like Figures 1-4As shown: A protective buffer structure for a level transmitter includes a buffer frame 2, which includes multiple buffer plates 3. Each buffer plate 3 includes a buffer rod 32. The upper and lower ends of the buffer rod 32 are respectively connected to a crossbar 33 and a sleeve 31. The sleeve 31 is bolted to the flange of the level transmitter body 1. The multiple buffer plates 3 are interconnected by a lower connecting member 4. The lower connecting member 4 includes a connecting rod 41 and a connecting rod 42. One end of the connecting rod 41 and the connecting rod 42 is rotatably connected to the sleeve 31 by a pin. The other end of the connecting rod 41 and the connecting rod 42 is respectively provided with a pin 43 and a locking groove 44. The pin 43 is adapted to... The device includes a snap-fit ​​slot 44. The end of the crossbar 33 is connected to an external threaded plate 34, which is threadedly connected to an upper connector 5. The buffer plate 3 can be connected to the level transmitter body 1 using bolts already installed on the body, eliminating the need for any cosmetic changes to the body and effectively improving the device's applicability. Multiple buffer plates 3, connected by the lower connector 4 and upper connector 5, quickly and stably form a single unit, providing reliable buffer protection for the level transmitter body 1. The snap-fit ​​slot 44 and pin 43 are staggered vertically, with the opening width of the snap-fit ​​slot 44 not exceeding the diameter of the pin 43. After unfolding, the pin 43 connects to the adjacent buffer plates 3 via the snap-fit ​​groove 44, allowing multiple buffer plates 3 to be stably connected as a whole. The buffer rod 32 is an elastic arc-shaped rod structure. When subjected to pressure from external objects, the buffer rod 32 undergoes elastic deformation, providing effective buffering protection in both radial and axial directions. The external threaded plate 34 is an arc-shaped plate structure. When multiple buffer plates 3 are connected as a whole via the lower connector 4, the axes of the multiple external threaded plates 34 are collinear. The upper connector 5 includes an internal threaded tube 51, which is threadedly connected to the external threaded plates 34. After the buffer plates 3 are securely installed on the level transmitter body 1... A connector 5 can be screwed onto the external threaded plate 34 to stably connect multiple buffer plates 3 into one unit. A limiting rod 52 is formed on the inner end face of the internal threaded tube 51. The curved side of the limiting rod 52 is slidably connected to the inner wall of the external threaded plate 34. The limiting rod 52 plays a limiting role and effectively supports the buffer plates 3 on the inner side of the external threaded plate 34, ensuring the stability of the connection between multiple buffer plates 3. The distance between the crossbar 33 and the top of the liquid level transmitter body 1 is not less than one centimeter. By maintaining a suitable initial distance between the crossbar 33 and the liquid level transmitter body 1, an effective movement space can be provided for the crossbar 33 when it is subjected to pressure and pushes the buffer rod 32 to deform.

[0031] The working principle of this technical solution is as follows: When installing the buffer frame 2, a single sleeve 31 is placed against and aligned with the flange bolt hole of the level transmitter body 1. The bolt is inserted into the bolt hole and the sleeve 31. After multiple buffer plates 3 are installed on the level transmitter body 1, the connecting rod 1 41 and the connecting rod 2 42 are rotated so that the connecting rod 2 42 installed on one buffer plate 3 is connected to the pin 43 on the connecting rod 1 41 installed on another buffer plate 3 through the snap-fit ​​groove 44. Thus, the multiple buffer plates 3 are connected into a whole through the connection of the lower connecting piece 4. Then, the operator screws the internal threaded pipe 51 onto the external threaded plate 34. At this time, the limiting rod 52 is supported on the inner side of the external threaded plate 34 to support the buffer plate 3, so that the buffer frame 2 plays the role of buffering, supporting and protecting the inner side of the level transmitter body 1.
