Description

Technical Field

[0001] This utility model belongs to the field of fixing device technology, and specifically relates to a truck urea pipe fixing device. Background Technology

[0002] The truck urea hose is a core component of the automotive SCR system, responsible for delivering urea solution from the urea tank to the exhaust pipe to participate in the exhaust gas purification reaction. When using the truck urea hose, a quick-connect interface for plugging into the urea pump needs to be inserted into the end of the hose. During the connection process, a device is needed to secure the urea hose.

[0003] Most existing fixing devices are horizontal, consisting of a base plate, a fixing seat, and a clamping plate. After the urea tube is inserted into the fixing seat, the clamping plate is lowered to clamp it. Although this is stable and reliable, there are other problems in use. For example, it does not have a quick push-in function. After the pipe is fixed, the lower end of the connector is placed in the pipe. Due to the thick pipe wall, the pressure on the connector is relatively large, which can easily cause the connector to tilt and fall out due to unbalanced force. It has poor flexibility and poor fixing effect. After the connector is inserted, the end of the urea tube will expand and deform outward. In order to avoid the inability to expand due to clamping, the end of the pipe often needs to be extended upward to keep it in a movable state. In this state, it is easy to bend as the connector is inserted, and personnel need to hold it to support it. Utility Model Content

[0004] The purpose of this utility model is to provide a truck urea pipe fixing device, which has the advantages of quick push-in function and good fixing effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a truck urea pipe fixing device, comprising a housing, wherein a bidirectional screw is rotatably connected to the inside of the housing via a bearing, and two fixing seats are threadedly connected to the surface of the bidirectional screw. Each of the two fixing seats has a slot on one side opposite to the other. A groove communicating with the slot is formed on the top of the fixing seat. A connecting seat is provided inside the groove. A fixing spring is bolted between one side of the connecting seat and the groove via a spring fixing plate. A mounting bracket is bolted to the top of the housing. A threaded rod is threadedly connected to the top of the mounting bracket. A pressure plate is rotatably connected to the bottom end of the threaded rod via a bearing.

[0006] The above technical solution achieves good fixation, provides adequate deformation space when the pipe is opened, avoids the inability to insert due to tight fixation, has good stability and flexibility, and also has a quick push-in function. It is simple and labor-saving to operate, improves the work efficiency of personnel, reduces the support burden of personnel, and is highly practical.

[0007] The present invention is further configured such that two limiting rods are provided through one side of the fixed base, and both ends of the limiting rods are welded to the inside of the housing.

[0008] The above technical solution is adopted: by setting the limit rod, the fixed seat can be limited to prevent it from flipping over during left and right movement.

[0009] The present invention is further configured such that a first throttle is bolted to the other end of the bidirectional screw, and a second throttle is bolted to the top end of the threaded rod.

[0010] The above technical solution allows operators to easily rotate the bidirectional screw or threaded rod by hand through the setting of the first and second throttles.

[0011] The present invention is further provided that a guide groove is provided at the bottom of the pressure plate.

[0012] The above technical solution allows for the positioning of the top of the joint by setting the guide groove, thus preventing the joint from shifting during the pressing process of the pressure plate.

[0013] The present invention is further configured such that two mounting plates are provided inside the housing.

[0014] The above technical solution allows operators to easily install and fix the housing with screws by setting up the mounting plate.

[0015] The present invention is further configured such that the bidirectional screw, the threaded rod, and the pressure plate are all made of stainless steel.

[0016] The above technical solutions feature high strength, low density, and excellent corrosion resistance in the bidirectional screw, threaded rod, and pressure plate.

[0017] The present invention is further configured such that the fixing spring is made of carbon spring steel.

[0018] Using the above technical solution, the fixed spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0019] In summary, this utility model has the following beneficial effects: 1. By bending the urea tube and placing it in the slot of the fixing seat, then holding the first throttle and rotating the double-ended screw, the double-ended screw will move the two fixing seats inward synchronously with the help of the limit rod. When the fixing seats move, they will fix the urea tube to the center. After the urea tube is fixed, the connector is placed in the pipe and pressed down. When the connector is pressed down, it will push the connecting seat outward. When the connecting seat moves outward, it will compress the fixing spring and cause it to contract. When the fixing spring contracts, it will not only provide thrust to the connecting seat, but also provide deformation space for the expansion of the urea tube. It can achieve good fixing effect and provide appropriate deformation space when the pipe is opened, avoiding the inability to insert due to tight fixing. It has good stability and flexibility. 2. When it is difficult to press the connector down, place the bottom end of the connector in the pipe, and then hold the second handle to rotate the threaded rod downward. When the threaded rod moves down, it will drive the pressure plate down with the help of the bearing. When the pressure plate moves down, it will place the top end of the connector in the guide groove at the bottom. Then, the continued rotation of the second handle will force the connector into the pipe. It has a quick push-in function, is simple and labor-saving to operate, improves the work efficiency of personnel, reduces the support burden of personnel, and is highly practical.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: refer to Figure 1 , Figure 2 and Figure 3A truck urea pipe fixing device includes a housing 1. A bidirectional screw 2 is rotatably connected to the inside of the housing 1 via bearings. Two fixing seats 3 are threaded onto the surface of the bidirectional screw 2. Each fixing seat 3 has a slot 4 on one opposite side. A groove 5 communicating with the slot 4 is formed on the top of each fixing seat 3. A connecting seat 6 is disposed inside the groove 5. A fixing spring 7 is bolted between one side of the connecting seat 6 and the groove 5 via a spring fixing plate. The urea pipe is bent and placed into the slot 4 within the fixing seat 3. Then, by holding the first throttle 12, the bidirectional screw 2 is rotated. The bidirectional screw 2 rotates... With the cooperation of the limiting rod 11, the two fixed seats 3 will move inward synchronously. When the fixed seat 3 moves, it will fix the urea tube to the center. After the urea tube is fixed, the connector is placed in the pipe and pressed down. When the connector is pressed down and the pipe is opened, it will push the connecting seat 6 outward. When the connecting seat 6 moves outward, it will compress the fixing spring 7 and cause it to contract. When the fixing spring 7 contracts, it will not only provide thrust to the connecting seat 6, but also provide deformation space for the expansion of the urea tube. It can achieve good fixing effect and provide appropriate deformation space when the pipe is opened, avoiding the inability to insert due to tight fixing. It has good stability and flexibility.

[0024] refer to Figure 2 Two limiting rods 11 are provided through one side of the fixed base 3. Both ends of the limiting rods 11 are welded to the inside of the housing 1. By setting the limiting rods 11, the fixed base 3 can be limited to prevent it from flipping over during left and right movement.

[0025] refer to Figure 1 and Figure 2 The housing 1 has two mounting plates 15 inside, which make it easy for operators to install and fix the housing 1 with screws.

[0026] refer to Figure 1 The fixed spring 7 is made of carbon spring steel and has excellent mechanical properties, good spring damping performance, low temperature resistance and corrosion resistance.

[0027] Brief description of the usage process: After bending the urea tube, place it in the slot 4 inside the fixed seat 3. Then, hold the first throttle 12 to drive the double-acting screw 2 to rotate. When the double-acting screw 2 rotates, it will drive the two fixed seats 3 to move inward synchronously with the cooperation of the limit rod 11. When the fixed seats 3 move, they will fix the urea tube to the center. After the urea tube is fixed, place the connector in the pipe and press it down. When the connector is pressed down, it will push the connecting seat 6 to move outward. When the connecting seat 6 moves outward, it will compress the fixing spring 7 and cause it to contract. When the fixing spring 7 contracts, it will not only provide thrust to the connecting seat 6, but also provide deformation space for the expansion of the urea tube.

[0028] Example 2: refer to Figure 1 , Figure 2 and Figure 4 A truck urea pipe fixing device is disclosed. A mounting bracket 8 is bolted to the top of the housing 1. A threaded rod 9 is threadedly connected to the top of the mounting bracket 8. A pressure plate 10 is rotatably connected to the bottom of the threaded rod 9 via a bearing. When it is difficult to press the connector down, the bottom of the connector is placed in the pipe, and then the second handle 13 is held by hand to rotate the threaded rod 9 downwards. As the threaded rod 9 moves downwards, it drives the pressure plate 10 downwards with the help of the bearing. As the pressure plate 10 moves downwards, the top of the connector is placed in the guide groove 14 at the bottom. The continued rotation of the second handle 13 then forces the connector into the pipe. This device features a quick-push-in function, is simple and labor-saving to operate, improves personnel efficiency, reduces the burden of support, and is highly practical.

[0029] refer to Figure 1 and Figure 2 The other end of the bidirectional screw 2 is bolted with a first throttle 12, and the top end of the threaded rod 9 is bolted with a second throttle 13. The setting of the first throttle 12 and the second throttle 13 makes it easy for the operator to rotate the bidirectional screw 2 or the threaded rod 9 by hand.

[0030] refer to Figure 4 The bottom of the pressure plate 10 is provided with a guide groove 14. The top of the connector can be positioned by the guide groove 14 to prevent the connector from shifting during the pressing process of the pressure plate 10.

[0031] refer to Figure 1 and Figure 2 The double-acting screw 2, threaded rod 9, and pressure plate 10 are all made of stainless steel. The double-acting screw 2, threaded rod 9, and pressure plate 10 have the characteristics of high strength, low density, and excellent corrosion resistance.

[0032] Brief description of the usage process: When it is difficult to press down the connector, place the bottom end of the connector in the pipe, and then hold the second handle 13 to drive the threaded rod 9 to rotate downward. When the threaded rod 9 moves downward, it will drive the pressure plate 10 to move downward together with the bearing. When the pressure plate 10 moves downward, it will place the top end of the connector in the bottom guide groove 14. Then, the continued rotation of the second handle 13 will force the connector into the pipe.
