Description

Technical Field

[0001] This utility model relates to the field of vehicle water tanks, and in particular to a sealing structure for a passenger vehicle heater water tank. Background Technology

[0002] The passenger car heater core is the core component of the car's air conditioning and heating system. Essentially, it is a heat exchange device that absorbs heat from the engine coolant, heats the air, and then sends it into the car to provide functions such as heating, defrosting, and defogging. It is an important component for ensuring driving comfort and safety.

[0003] A sealing structure refers to a structure that isolates or controls the internal space of an object or system from the external environment (such as air, water, dust, gas, etc.) through specific design, materials, and combinations. Its core purpose is to prevent leakage of internal media and prevent the intrusion of external impurities and pollutants, so as to ensure the normal operation, safety, reliability, and stable performance of equipment, systems, or devices.

[0004] However, traditional heater cores are equipped with inlet and outlet ports, and high-temperature hoses are fitted onto their surfaces. After connection, the high-temperature hoses are fixed and pressed to the inlet or outlet port by adjustable clamps. However, they do not have an internal sealing structure, which may cause water leakage at the connection point after long-term use. Therefore, a sealing structure for passenger car heater cores is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sealing structure for a passenger vehicle heater core, which aims to improve the problem that the lack of an internal sealing structure may lead to water leakage at the connection points after long-term use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sealing structure for a passenger vehicle heater water tank, comprising a water tank body, wherein a water inlet pipe is fixedly connected to the left side wall of the water tank body, and a clamping mechanism is provided on the surface of the water inlet pipe;

[0007] The clamping mechanism includes a fixing bolt a, a rotating block is threadedly connected to the outer wall of the fixing bolt a, a fixing block is rotatably connected to the bottom of the rotating block, a hinge rod is hinged to the side wall of the rotating block, a connecting block is hinged to the end of the hinge rod away from the rotating block, a reinforcing clamp is fixedly connected to the lower surface of the connecting block, a sliding block is slidably connected to the inner wall of the reinforcing clamp, and a sealing mechanism is provided on the surface of the water inlet pipe.

[0008] As a further description of the above technical solution:

[0009] The sealing mechanism includes a fixing bolt b, the outer wall of which is threaded with a sliding sleeve, and the end of the sliding sleeve away from the fixing bolt b is in contact with a sealing ring.

[0021] The surface of the water inlet pipe is provided with an annular groove, and the sealing ring is fitted onto the surface of the annular groove of the water inlet pipe.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a clamping mechanism is provided. By rotating the rotating block, the hinge rods are driven to move closer together. The hinge rods drive the two sets of reinforcing clamps to move closer together, thereby pressing and fixing the external water inlet pipe. Adjusting the distance between the two sets of reinforcing clamps can make the fixing of water inlet pipes of different diameters more universal. At the same time, the fixing bolts can make the reinforcing clamps firmly fix the external water inlet pipe.

[0024] 2. In this utility model, a sealing structure is provided. By sliding the sliding sleeve, the sliding sleeve compresses the sealing ring. The sealing ring deforms in all directions under compression, fitting into the inner wall of the external water pipe, thus achieving a quick and convenient sealing effect. At the same time, the movable sliding sleeve allows for multiple compression deformations of the sealing ring, thereby enhancing the sealing effect. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a passenger vehicle heater core sealing structure, including a tank body 1. The heater core is a core component of the passenger vehicle's air conditioning heating system. The tank body 1 serves as a key carrier and achieves multiple functions such as heat exchange, medium storage, and system connection through structural design and functional integration. A water inlet pipe 2 is fixedly connected to the left side wall of the tank body 1. Two sets of water pipes are provided on the surface of the tank body, namely the water inlet pipe 2 and the water outlet pipe. The water inlet pipe 2 serves as a key pipeline connecting the engine cooling system and the heater core. A clamping mechanism 3 is provided on the surface of the water inlet pipe 2.

[0033] Reference Figures 2-4The clamping mechanism 3 includes a fixing bolt a31, a rotating block 32 threadedly connected to the outer wall of the fixing bolt a31, a fixing block 33 rotatably connected to the bottom of the rotating block 32, and a fixing block 33 fixedly connected to the lower surface of the fixing block 33 to the outer wall of the sliding sleeve 42. The surface of the fixing block 33 has a threaded groove, and the outer wall of the fixing bolt a31 is threadedly connected to the inner wall of the fixing block 33. The function of the fixing bolt a31 is to fix the rotating block 32 after rotation. The rotation of the rotating block 32 causes the hinge rods 34 to move closer together or further apart, and the fixation between them is achieved through the self-locking property of the threads of the fixing bolt a31. A hinge rod 34 is hinged to the side wall of the rotating block 32, and a connecting block 3 is hinged to the end of the hinge rod 34 away from the rotating block 32. 5. A reinforcing clamp 36 is fixedly connected to the lower surface of the connecting block 35. When the rotating block 32 rotates, it will simultaneously pull the two sets of hinge rods 34 on the surface to rotate around the center, so that the corresponding hinged connecting block 35 drives the bottom reinforcing clamp 36 to move closer or further away from each other. In addition, the inner wall of the reinforcing clamp 36 is provided with rubber anti-slip grooves, which makes the reinforcing clamp 36 more firmly clamped and fixed to the outer wall of the external water pipe, and increases friction. The inner wall of the reinforcing clamp 36 is slidably connected with a sliding block 37. Two sets of sliding blocks 37 are provided. Both sets of sliding blocks 37 are fixedly connected to the surface of the sliding sleeve 42. The function of the sliding block 37 is to guide the movement position of the reinforcing clamp 36. A sealing mechanism 4 is provided on the surface of the water inlet pipe 2.

[0034] Reference Figure 1 and Figures 3-4 The sealing mechanism 4 includes a fixing bolt b41. The bottom end of the outer wall of the fixing bolt b41 contacts the outer arc surface of the water inlet pipe 2. A sliding sleeve 42 is threadedly connected to the outer wall of the fixing bolt b41. By rotating the fixing bolt b41 and moving the sliding sleeve 42 downwards along the inner thread, it can contact the surface of the water inlet pipe 2. The sliding sleeve 42 is fixed by the self-locking property of the thread of the fixing bolt b41. The inner wall of the sliding sleeve 42 is slidably connected to the outer wall of the water inlet pipe 2. A circular groove is formed on the surface of the water inlet pipe 2, so that the sliding sleeve 42 can only move within the circular groove. The sliding sleeve 42 moves left and right within the groove. The end of the sliding sleeve 42 away from the fixing bolt b41 contacts the sealing ring 43. The surface of the water inlet pipe 2 has an annular groove. The sealing ring 43 is fitted onto the surface of the annular groove of the water inlet pipe 2. The sealing ring 43 is made of soft rubber. By squeezing the sealing ring 43 with the sliding sleeve 42, the sealing ring 43 will deform and fit against the inner wall of the external water pipe, thus achieving a sealing effect. Furthermore, the external connecting pipe can be fitted onto the outside of the water inlet pipe 2 with a clamp, so that the sealing ring 43 makes contact and seal at the point where the external connecting pipe and the water inlet pipe 2 are connected.

[0035] Working principle: When using this device, the external water pipe is connected to the inlet of the water inlet pipe 2. Then, the fixing bolt a31 is loosened, so that the fixing bolt a31 is no longer in contact with the surface of the water inlet pipe 2. Then, the sliding sleeve 42 is pushed to the left, so that the sliding sleeve 42 squeezes the sealing ring 43. The force generated by the squeeze will deform the outer wall of the sealing ring 43, so that the sealing ring 43 squeezes the inner wall of the external water inlet pipe interface to complete the seal. After the movement is completed, the fixing bolt b41 is rotated in the reverse direction in the internal thread of the sliding sleeve 42 and contacts the current position of the water inlet pipe 2. With the self-locking property of the thread of the fixing bolt b41, the position of the sliding sleeve 42 is fixed.

[0036] Meanwhile, reinforcing clamps 36 are provided on both sides of the sliding sleeve 42. First, rotate the fixing bolt a31 to disengage it from the threaded groove at the bottom of the fixing block 33. Rotate the fixing bolt a31, which drives the rotating block 32 to rotate around the center. The rotating block 32 rotates around the center, which drives the two hinge rods 34 to move closer together. The two sets of hinge rods 34 move closer together, which drives the two sets of connecting blocks 35 to move closer together. The two sets of connecting blocks 35 move closer together, which drives the two sets of reinforcing clamps 36 to move closer together, so that the reinforcing clamps 36 firmly clamp the outer wall of the external water pipe. Finally, the fixing bolt a31 is threaded into the threaded groove at the current position of the fixing block 33. Thus, when the external connecting pipe is sleeved on the inlet pipe 2, the reinforcing clamps 36 can stably press the external connecting pipe. When it is necessary to disassemble the external connecting pipe, the operation can be reversed.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
