Description

Technical Field

[0001] The utility model relates to the field of assembly structures, and particularly relates to an assembly structure for a urea sensor. Background Technique

[0002] At present, the Chinese utility model with the publication number of CN219974605U discloses an assembly structure of a urea quality sensor and a urea tank, including a urea tank body and a urea sensor body. The urea sensor body is installed in the urea tank. Through holes are respectively opened on the inner walls of both sides of the placement opening at the top of the urea tank body. Clamping rods are arranged in the through holes in a matching manner. Adjusting mechanisms for controlling the movement of the clamping rods are arranged on the outer walls of both sides of the placement opening at the top of the urea tank body, so as to avoid the urea sensor body from shaking, disturbing the urea solution, and reducing the generation of bubbles in the urea solution. By combining the present utility model with the existing installation method, the two methods are combined, and the stability effect of the urea sensor is better.

[0003] Although the existing assembly structure has good stability and can avoid the urea sensor from shaking after being placed, there are still other problems in the use process. For example, it does not have a highly micro-adjustable function. When the length of the urea sensor is fixed and the placed urea tank is relatively shallow, it will cause the bottom end of the sensor to collide with the urea tank, and the installation parts between the two cannot be in contact and fixed, reducing the applicability of the device. Moreover, it is not convenient to quickly disassemble and assemble the sensor. When the urea sensor needs to be maintained during use, the sensor needs to be taken out of the urea tank. Since the sensor is directly fixed by screws, tools are required to assist in the disassembly and assembly process, reducing the maintenance efficiency of personnel and having low practicability. To solve the above problems, we propose an assembly structure for a urea sensor. Content of the Utility Model

[0004] The purpose of the utility model is to provide an assembly structure for a urea sensor, which solves the problems that the existing assembly structure cannot micro-adjust the height of the sensor and is rather cumbersome when disassembling and assembling the sensor.

[0005] The above technical object of the utility model is achieved through the following technical solutions: An assembly structure for a urea sensor, including a urea tank, a fixing frame is placed on the top of the urea tank, an installation sleeve is welded on the top of the fixing frame, a urea sensor is slidably connected inside the installation sleeve, threaded rods are equidistantly installed on the surface of the urea sensor, fixing nuts are threadedly connected to the surface of the threaded rods, a sliding groove is opened at the top of the installation sleeve, a limiting sleeve is welded inside the fixing frame, two clamping plates are arranged inside the fixing frame, a fixing spring is bolted between one side of the clamping plate and the fixing frame through a spring fixing piece, a fixing rod is welded on one side of the clamping plate, and the other end of the fixing rod penetrates and extends to the outside of the fixing frame.

[0006] Adopting the above technical solutions can facilitate the quick disassembly and assembly of the sensor by personnel, with simple and labor-saving operation, accelerating the maintenance and repair efficiency of personnel, high practicability, and at the same time being able to slightly adjust the height of the sensor, improving the applicable range of the structure and having good flexibility.

[0007] The utility model is further arranged as: Anticorrosive coatings are applied on the surfaces of the fixing frame and the installation sleeve.

[0008] Adopting the above technical solutions, through the setting of the anticorrosive coating, the anti-corrosion effect on the surfaces of the fixing frame and the installation sleeve can be improved, and the service life of the fixing frame and the installation sleeve is prolonged.

[0009] The utility model is further arranged as: The number of the threaded rods, the fixing nuts and the sliding grooves is four each.

[0010] Adopting the above technical solutions can improve the stability between the urea sensor and the installation sleeve, and avoid the situation of the urea sensor falling off.

[0011] The utility model is further arranged as: The threaded rods and the fixing nuts are both made of stainless steel.

[0012] Adopting the above technical solutions, the threaded rods and the fixing nuts have the characteristics of high strength, low density and excellent corrosion resistance.

[0013] The utility model is further arranged as: A limiting rod is welded on one side of the clamping plate, and the other end of the limiting rod penetrates and extends to the outside of the fixing frame.

[0014] Adopting the above technical solutions, through the setting of the limiting rod, the clamping plate can be limited to prevent the clamping plate from tilting during the left-right movement.

[0015] The utility model is further arranged as: A sealing ring is fixedly sleeved inside the fixing frame.

[0016] With the above technical solution, through the setting of the sealing ring, the sealing effect between the top of the urea tank and the inside of the fixed frame can be improved.

[0017] The present utility model is further configured as: a protective pad that fits the urea tank is bonded to the other side of the clamping plate.

[0018] With the above technical solution, through the setting of the protective pad, the urea tank can be protected, and the surface of the urea tank can be prevented from being scratched during the clamping process by the clamping plate.

[0019] The present utility model is further configured as: the other end of the fixed rod penetrates to the outside of the fixed frame and is welded with a pull ring.

[0020] With the above technical solution, through the setting of the pull ring, it is convenient for personnel to pull the fixed rod.

[0021] The present utility model is further configured as: the fixed spring is made of carbon spring steel.

[0022] With the above technical solution, the fixed spring has the characteristics of excellent mechanical properties, good anti-fatigue reduction performance, low temperature resistance and corrosion resistance.

[0023] The present utility model is further configured as: the diameter of the limiting sleeve is the same as the inner diameter of the opening at the top of the urea tank.

[0024] With the above technical solution, after being placed, it fits with the inside of the urea tank to avoid shaking.

[0025] In summary, the present utility model has the following beneficial effects:

[0026] 1. In the present utility model, first, hold the two pull rings with both hands and pull them outwards. When the pull rings are pulled outwards, they will drive the fixed rod and the clamping plate to move outwards through the cooperation of the limiting rods. When the clamping plate moves outwards, it will squeeze the fixed spring to make it contract and deform. When the pull rings are pulled out to the end, place them on the urea tank, and finally release the hands holding the pull rings. Since the fixed spring has elasticity, when the fixed spring rebounds, it will push the protective pad to clamp onto the urea tank, which is convenient for personnel to quickly disassemble and assemble the sensor, with simple and labor-saving operation, accelerating the maintenance and repair efficiency of personnel, and high practicality;

[0027] 2. In the present utility model, pick up the urea sensor, and after picking up the urea sensor, vertically place it downwards into the installation sleeve. When the urea sensor is placed, the threaded rod needs to slide into the corresponding sliding groove, and then hold the urea sensor and slowly lower it. When the urea sensor is lowered to the appropriate position, use a tool to tighten the fixing nut. After the fixing nut is tightened until it contacts the installation sleeve, the urea sensor can be fixed, and the height of the sensor can be slightly adjusted, improving the applicable range of the structure and having good flexibility.
