Description

Technical Field

[0001] This utility model relates to the field of urea pump assembly technology, and in particular to a modular quick-release urea pump. Background Technology

[0002] The urea pump is a crucial component of the urea solution injection metering system. Its main function is to draw urea solution from the urea tank, maintain a certain pressure, and then deliver it to the injection unit to meet the flow and pressure requirements of the injection metering system. Traditional urea pumps are primarily designed for direct bolt mounting, where the pump body and motor are connected using long bolts, which also serve as supports and fixations. However, during installation, it is difficult to achieve precise alignment of the bolt holes, which can obstruct the bolt insertion process. This necessitates constant adjustments to the pump body or motor's position. Since the pump body and motor are relatively heavy, this increases the intensity of movement and adjustment work, making the operation cumbersome and time-consuming. This inconvenience is even more pronounced in scenarios requiring frequent maintenance or replacement of the urea pump, severely impacting work efficiency.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes a modular quick-release urea pump, which solves the aforementioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A modular quick-release urea pump includes a bracket, a fixing block is fixedly connected to one side of the bracket, a socket is opened on one side of the fixing block, a pin is inserted into the socket, movable cavities are opened on both sides of the socket, a fixing shaft is fixedly installed in the inner cavity of the movable cavity, a locking pin is rotatably installed on the surface of the fixing shaft, the end of the locking pin facing the pin is locked on the pin, triangular blocks are symmetrically arranged on both sides of the inner cavity of the movable cavity, four springs are fixedly connected to the inclined side of the triangular blocks, and the ends of the springs away from the triangular blocks are fixedly connected to the locking pins.

[0006] The present invention, as described above, is used for a modular quick-release urea pump. Further, one side of the pin is provided with an inclined surface, and a recess adapted to the end of the locking pin is formed between the inclined surface and the side plane of the pin's tail end.

[0007] The present invention, as described above, is used for a modular quick-release urea pump. Further, a limiting groove is provided on one side of the inner cavity of the movable chamber, a limiting rod is slidably installed in the inner cavity of the limiting groove, and one end of the limiting rod extends out of the inner cavity of the limiting groove and is fixedly connected to the locking pin.

[0008] The present invention, as described above, is used for a modular quick-assembly urea pump. In a further step, pre-installation holes are provided at all four corners of one side of the bracket.

[0009] The present invention, as described above, is used for a modular quick-release urea pump. Further, a pump body is fixedly connected to one side of the bracket, and a motor adapted to the pump body is fixedly connected to one end of the pin.

[0010] The present invention provides a modular quick-release urea pump as described above, further comprising: a pressure regulating port is provided on one side of the top of the pump body, and a pressure regulating bolt is installed in the internal thread of the pressure regulating port.

[0011] The present invention, as described above, is used for a modular quick-release urea pump. Further, the output end of the motor is fixedly connected with a locking pin, and a rotating shaft is rotatably installed inside the pump body. One end of the rotating shaft has a groove that matches the locking pin.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a modular quick-disassembly structure design. Operators can quickly connect and disassemble the motor and pump body by simply plugging in the connection, which greatly improves work efficiency. Even in some scenarios where the urea pump needs to be frequently inspected or replaced, the ease of disassembly and assembly of the urea pump is highlighted, providing convenience for users' work.

[0014] 2. This utility model features a sloping surface at a 45-degree angle, which creates a ramp that allows the end of the locking pin to slide smoothly over the surface and engage with the bolt, preventing the bolt from shifting back and ensuring a secure and stable connection between the bolt and the fixing block. This provides convenience for users.

[0015] 3. This utility model, through the setting of a limiting slide groove and a limiting slide rod, allows the locking pin to drive the limiting slide rod to slide within the limiting slide groove during the rotation of the locking pin, thereby limiting the locking pin. Simultaneously, the semi-circular shape of the limiting slide groove further restricts the locking pin from continuing to rotate into the fixed block within its original movement range, thus ensuring the tightness and firmness of the connection between the fixed block and the pin, providing convenience for users.

[0016] 4. This utility model features pre-installed holes, which are pre-drilled on the bracket for inserting mounting bolts. This allows operators to directly insert bolts into the pre-installed holes when installing the urea pump, eliminating the need for subsequent drilling and allowing for quick assembly of the urea pump. It also improves the stability of the urea pump's operation.

[0017] 5. This utility model, through the arrangement of the pump body and the motor, uses the motor to drive the pump body to work. When the urea pump is working, the motor starts to work, and the motor will transmit power to the pump body through the locking pin, thereby driving the pump body to work normally, ensuring the normal operation of the urea pump, and providing convenience for users' work and use.

[0018] 6. This utility model features a pressure regulating port, which is used to adjust the large spring inside the pump body's safety valve. Specifically, this bolt can adjust the spring's compression, thereby adjusting the valve's opening pressure. When the pump is over-pressurized, the safety valve will open to protect the pump from overload and prevent the pump body from bursting.

[0019] 7. With the setting of the locking pin and the locking groove, after the motor and the pump body are connected and installed together, the locking pin will be inserted into the locking groove. When the motor starts working, the output will drive the locking pin to rotate. With the cooperation of the locking groove, the locking pin will drive the rotating shaft on the pump body to rotate, thereby driving the pump body to work, ensuring the normal operation of the urea pump, and also realizing the modular and quick assembly and disassembly of the urea pump.

Detailed Implementation

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0028] A modular quick-release urea pump includes a bracket 1. A fixing block 2 is fixedly connected to one side of the bracket 1. A socket 4 is opened on one side of the fixing block 2. A pin 3 is inserted into the socket 4. Movable cavities 5 are opened on both sides of the inner cavity of the socket 4. A fixing shaft 6 is fixedly installed in the inner cavity of the movable cavity 5. A locking pin 7 is rotatably installed on the surface of the fixing shaft 6. The end of the locking pin 7 facing the pin 3 is locked onto the pin 3. Triangular blocks 8 are symmetrically arranged on both sides of the inner cavity of the movable cavity 5. Four springs 9 are fixedly connected to the inclined side of the triangular blocks 8. The end of the spring 9 away from the triangular blocks 8 is fixedly connected to the locking pin 7.

[0029] The specific usage process is as follows: During installation, first place the pump body 15 or motor 14 in a suitable position, or fix the motor 14 and pump body 15. For example, first install the motor 14 or pump body 15 onto the equipment, and then lift the motor 14 or pump body 15. The following explanation takes the installation and fixing of the motor 14 as an example. After fixing the motor 14, you can lift or raise the pump body 15. Align the pin 3 on the motor 14 with the socket 4 on the fixing block 2, and then pass the pin 3 through the socket 4 until it comes out from the other side of the socket 4, until the motor 14 and pump body 15 are connected. At this time, the end of the locking pin 7 facing the inclined surface 10 will be stuck on the inclined surface 10, that is, stuck in the recess corresponding to the pin 3. The locking pin 7 is set at an angle. The limiting slide bar 12 can only slide within a limited angle within the limiting slide groove 11, which also limits the locking pin 7, making it able to rotate only outwards and difficult to rotate inwards. This, in turn, restricts the insertion pin 3, preventing it from moving back. It should be noted that, in addition to limiting it through the limiting slide bar 12 and the limiting slide groove 11, the length of the outer opening of the movable cavity 5 can also be changed so that when the locking pin 7 rotates inwards towards the fixed block 2, it will be blocked by the inner wall of the fixed block 2. This design can also prevent the insertion pin 3 from moving back. Thus, the operator only needs to insert the insertion pin 3 directly into the fixed block 2 to complete the installation and connection of the motor 14 and the pump body 15. In order to improve the tightness and stability of the operation of the motor 14 and the pump body 15, the electric... The motor 14 and pump body 15 are then connected and fixed with long bolts. Because the pin 3 is inserted into the fixing block 2, the screw holes on the motor 14 and pump body 15 can be precisely aligned. At this time, the long bolt can be inserted into the screw holes on the motor 14 and pump body 15, improving the speed and efficiency of bolt installation. When the pin 3 is inserted into the socket 4, the end of the pin 3 will touch the ends of the two locking pins 7, thereby pressing the two locking pins 7 outward and rotating them outward. The locking pins 7 rotate on the fixed shaft 6. At the same time, the two ends of the locking pins 7 will compress the corresponding springs 9. Simultaneously, the limiting slide rod 12 will slide with the locking pins 7 in the limiting slide groove 11, thereby limiting the rotation of the locking pins 7. Afterward, the end of the locking pin 7 will pass through the pin 3. The pin 7 moves to the side and then abuts against the inclined surface 10. Finally, the end of the locking pin 7 is engaged with the pin 3 and has a recess in the inclined surface 10, completing the assembly of the pin 3 and the fixing block 2. When the end of the locking pin 7 moves to the position of the inclined surface 10, the spring 9 will extend and return to its original position, thus allowing the end of the locking pin 7 to abut against the inclined surface 10 and quickly engage with the pin 3 and have a recess in the inclined surface 10. During disassembly, press the end of the locking pin 7 that is exposed to the outside and squeeze it into the fixing block 2. At this time, the other end of the locking pin 7, that is, the end that is engaged with the pin 3, will rotate outward and then disengage from the pin 3. At this time, the pin 3 can be pulled out from the fixing block 2 to complete the disassembly, that is, to disassemble and remove the motor 14 and the pump body 15.After disassembly, the inclined plane 10 is set at a 45-degree angle, forming a slope that allows the end of the locking pin 7 to slide smoothly and engage with the pin 3, preventing the pin 3 from shifting back and ensuring the firmness and stability of the connection between the pin 3 and the fixing block 2. This provides convenience for the user. During the rotation of the locking pin 7, it drives the limiting slide rod 12 to slide within the limiting slide groove 11, thus limiting the locking pin 7. The semi-circular shape of the limiting slide groove 11 further restricts the locking pin 7 from rotating further into the fixing block 2 within its original movement range, ensuring the tightness and firmness of the connection between the fixing block 2 and the pin 3. This provides convenience for the user. The pre-installed hole 13 is pre-drilled on the bracket 1 for inserting the mounting bolt. This allows the operator to directly insert the bolt into the pre-installed hole 13 when installing the urea pump, eliminating the need for subsequent drilling and enabling rapid assembly of the urea pump. This also improves the stability of the urea pump's operation. Motor 14 drives pump body 15. When the urea pump is working, motor 14 starts and transmits power to pump body 15 via locking pin 18, thus ensuring the normal operation of pump body 15 and providing convenience for users. The pressure regulating port 17 is used to adjust the large spring inside the pump body's safety valve. Specifically, this bolt adjusts the spring's compression, thereby regulating the valve's opening pressure. When the pump is over-pressurized, the safety valve opens to protect the pump from overload and prevent pump body bursting. After motor 14 and pump body 15 are connected and installed together, locking pin 18 is inserted into locking groove 19. When motor 14 starts working, its output drives locking pin 18 to rotate. Locking pin 18, in conjunction with locking groove 19, drives the rotating shaft on pump body 15 to rotate, thus driving pump body 15 to work and ensuring the normal operation of the urea pump. This also allows for modular and quick assembly / disassembly of the urea pump.

[0030] Therefore, the modular quick-disassembly structure design allows operators to quickly connect and disconnect the motor and pump body by simply plugging them in, greatly improving work efficiency. Even in scenarios where frequent maintenance or replacement of the urea pump is required, the ease of disassembly and assembly of the urea pump is highlighted, providing convenience for users' work.

[0031] A bevel 10 is provided on one side of the pin 3, and a recess is formed between the bevel 10 and the tail end side plane of the pin 3 to fit the end of the locking pin 7.

[0032] Specifically, the inclined surface 10 is set at a 45-degree angle to form a slope, allowing the end of the locking pin 7 to slide smoothly over it. This also allows the end of the locking pin 7 to be locked onto the pin 3, preventing the pin 3 from shifting back and ensuring the firmness and stability of the connection between the pin 3 and the fixing block 2, thus providing convenience for the user's work.

[0033] A limiting groove 11 is provided on one side of the inner cavity of the movable cavity 5. A limiting rod 12 is slidably installed in the inner cavity of the limiting groove 11. One end of the limiting rod 12 extends out of the inner cavity of the limiting groove 11 and is fixedly connected to the locking pin 7.

[0034] Specifically, the limiting slide groove 11 and the limiting slide rod 12 are designed so that when the locking pin 7 rotates, the locking pin 7 will drive the limiting slide rod 12 to slide within the limiting slide groove 11, thereby limiting the locking pin 7. At the same time, the limiting slide groove 11 is semi-circular in shape, which can also restrict the locking pin 7 from continuing to rotate into the fixed block 2 within the original set movement range, thereby ensuring the tightness and firmness of the connection between the fixed block 2 and the pin 3, and providing convenience for the user's work.

[0035] Pre-installed holes 13 are provided at each of the four corners on one side of the bracket 1.

[0036] Specifically, the pre-installed hole 13 is pre-drilled on the bracket 1 for inserting mounting bolts. This allows the operator to directly insert the bolts into the pre-installed hole 13 when installing the urea pump, eliminating the need for subsequent drilling and allowing for quick assembly of the urea pump, while also improving the stability of the urea pump's operation.

[0037] A pump body 15 is fixedly connected to one side of the bracket 1, and a motor 14 adapted to the pump body 15 is fixedly connected to one end of the pin 3.

[0038] Specifically, regarding the configuration of the pump body 15 and the motor 14, the motor 14 is used to drive the pump body 15 to work. When the urea pump is working, the motor 14 is started and works. The motor 14 will transmit power to the pump body 15 through the locking pin 18, thereby driving the pump body 15 to work normally, ensuring the normal operation of the urea pump, and providing convenience for users' work.

[0039] A pressure regulating port 17 is provided on one side of the top of the pump body 15, and a pressure regulating bolt 16 is installed inside the pressure regulating port 17.

[0040] Specifically, the pressure regulating port 17 is used to adjust the large spring inside the pump body safety valve. In particular, this bolt can adjust the compression of the spring, thereby adjusting the valve opening pressure. When the pump is over-pressurized, the safety valve will open to protect the pump from overload and prevent the pump body from bursting.

[0041] The output end of the motor 14 is fixedly connected to a locking pin 18, and a rotating shaft is rotatably installed inside the pump body 15. One end of the rotating shaft is provided with a slot 19 that matches the locking pin 18.

[0042] Specifically, with the setting of the locking pin 18 and the locking slot 19, after the motor 14 and the pump body 15 are connected and installed together, the locking pin 18 will be inserted into the locking slot 19. In this way, when the motor 14 starts working, the output will drive the locking pin 18 to rotate. With the cooperation of the locking slot 19, the locking pin 18 will drive the rotating shaft on the pump body 15 to rotate, thereby driving the pump body 15 to work, ensuring the normal operation of the urea pump, and also realizing the modular and quick disassembly and assembly of the urea pump.

[0043] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
