Description

Technical Field

[0001] This utility model belongs to the field of heater duct covers, specifically an automotive heater duct cover device. Background Technology

[0002] The car heater duct is an important connecting structure in the car heating system. The end of the car heater duct is usually equipped with a heater duct cover. The car heater duct cover is an important part of the vehicle heating system and is usually used to cover or close the heater duct.

[0003] When using a car heater duct cover, it is installed by snapping it onto the heater duct. After installation, the sealing gasket inside the cover ensures a tight seal between the duct and the cover, thus sealing the heater duct. However, in actual use, due to the inevitable bumps and vibrations during vehicle operation, the force of these vibrations is transmitted to the heater duct cover, causing it to move and gradually creating gaps between it and the heater duct. This affects the seal between the cover and the heater duct, leading to heat loss and reduced heating efficiency.

[0004] In summary, this utility model provides an automotive heater duct cover device to solve the above-mentioned problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A car heater duct cover device includes a pipe body, one end of which is provided with a sealing element, and the surface of the pipe body is provided with a friction element. The inner cavity of the sealing element is provided with a buffer element. The sealing element includes a cover, one side of the inner cavity of the cover is fixedly connected to a sealing ring, and the other side of the inner cavity of the cover is fixedly connected to a threaded ring. The friction element includes a collar, and the inner wall of the collar is fixedly connected to a friction pad. The buffer element includes two arc-shaped plates, and a spring is provided between the two arc-shaped plates. The inner cavity of the spring is provided with a damper.

[0007] Furthermore, in this invention, the tube body penetrates the inner cavity of the threaded ring and extends to the inner cavity of the cover, and is threadedly connected to the inner cavity of the threaded ring.

[0008] Furthermore, in this utility model, a limiting groove is formed on one side of the sealing ring, and one end of the tube extends into the inner cavity of the limiting groove and contacts the inner wall of the limiting groove.

[0009] Furthermore, in this utility model, a connecting plate is fixedly connected to the upper and lower ends of one side of the collar, and the end of the connecting plate away from the collar is fixedly connected to the sleeve cover. The friction pad and the collar are sleeved on the surface of the tube body, and the friction pad is in contact with the surface of the tube body.

[0010] Furthermore, in this utility model, both ends of the spring and both ends of the damper are fixedly connected to the arc-shaped plate, and the arc-shaped plate, spring and damper all extend into the inner cavity of the tube, and the arc-shaped plate is in contact with the inner wall of the tube.

[0011] Furthermore, in this utility model, a T-shaped groove is provided on one side of the inner cavity of the cover, and a T-shaped block is fixedly connected to one side of the arc plate. One end of the T-shaped block is located in the inner cavity of the T-shaped groove and is slidably connected to the inner cavity of the T-shaped groove.

[0012] Beneficial effects: This utility model has the following beneficial effects:

[0013] This invention uses a sleeve cap to drive a threaded ring to rotate. During rotation, the tube body and the threaded ring are threaded together, and the tube body enters the inner cavity of the sleeve cap and contacts the sealing ring. The sealing ring seals the tube body, ensuring its airtightness. At the same time, the sleeve cap drives the sleeve ring and friction pad to fit on the surface of the tube body, and the buffer enters the interior of the tube body. Therefore, during vibration, the friction pad increases the friction force in contact with the tube body, thus preventing connection wobbling. The vibration force is transmitted to the arc plate, which causes the spring and damper to deform, thereby buffering the vibration force. At the same time, the restoring force of the spring and damper cancels out the vibration force, thus achieving vibration reduction and preventing gaps caused by vibration from affecting the airtightness.

Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides an automotive heater duct cover device, including a pipe body 1. One end of the pipe body 1 is provided with a sealing member 2, and the surface of the pipe body 1 is provided with a friction member 3. The inner cavity of the sealing member 2 is provided with a buffer member 4. The sealing member 2 includes a cover 21. A sealing ring 22 is fixedly connected to one side of the inner cavity of the cover 21, and a threaded ring 23 is fixedly connected to the other side of the inner cavity of the cover 21. The friction member 3 includes a collar 31, and a friction pad 32 is fixedly connected to the inner wall of the collar 31. The buffer member 4 includes an arc plate 41, and there are two arc plates 41. A spring 42 is provided between the two arc plates 41, and a damper 43 is provided in the inner cavity of the spring 42.

[0023] like Figure 1-4 As shown, the sleeve cover 21 drives the threaded ring 23 to rotate. During the rotation, the tube body 1 and the threaded ring 23 will be threadedly connected, and the tube body 1 will enter the inner cavity of the sleeve cover 21 and contact the sealing ring 22. The sealing ring 22 seals the tube body 1 to ensure its airtightness. At the same time, the sleeve cover 21 drives the collar ring 31 and the friction pad 32 to be fitted on the surface of the tube body 1, and the buffer 4 enters the interior of the tube body 1. When vibration occurs, the friction pad 32 increases the friction force in contact with the tube body 1, thereby preventing the connection from shaking. The vibration force will be transmitted to the arc plate 41, which will cause the spring 42 and the damper 43 to deform, thereby buffering the vibration force. At the same time, the restoring force of the spring 42 and the damper 43 will cancel the vibration force, thereby achieving vibration reduction and preventing gaps caused by vibration from affecting the airtightness.

[0024] Example 2

[0025] Reference Figure 1 , 2 4 and 5 represent the second embodiment of this utility model, which is based on the previous embodiment.

[0026] In this embodiment, the tube body 1 penetrates the inner cavity of the threaded ring 23 and extends to the inner cavity of the sleeve 21, and is threadedly connected to the inner cavity of the threaded ring 23.

[0027] A limiting groove 221 is provided on one side of the sealing ring 22, and one end of the tube body 1 extends into the inner cavity of the limiting groove 221 and contacts the inner wall of the limiting groove 221.

[0028] A connecting plate 311 is fixedly connected to the upper and lower ends of one side of the collar 31. The end of the connecting plate 311 away from the collar 31 is fixedly connected to the cover 21. The friction pad 32 and the collar 31 are sleeved on the surface of the tube body 1, and the friction pad 32 is in contact with the surface of the tube body 1.

[0029] like Figure 1 , 2 As shown in Figure 4, the tube body 1 and the threaded ring 23 are connected by threads, which ensures a firm connection. One end of the tube body 1 enters the inner cavity of the limiting groove 221 and contacts it, thereby sealing one end of the tube body 1 and ensuring a tight seal. The friction pad 32 contacts the tube body 1, thereby increasing the friction between the two and preventing slippage. The connecting plate 311 connects the collar 31 and the cover 21 to achieve synchronous movement.

[0030] Example 3

[0031] Reference Figure 3 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0032] In this embodiment, both ends of the spring 42 and both ends of the damper 43 are fixedly connected to the arc plate 41. The arc plate 41, the spring 42 and the damper 43 all extend into the inner cavity of the tube body 1, and the arc plate 41 contacts the inner wall of the tube body 1.

[0033] A T-shaped groove 211 is provided on one side of the inner cavity of the cover 21, and a T-shaped block 411 is fixedly connected to one side of the arc plate 41. One end of the T-shaped block 411 is located in the inner cavity of the T-shaped groove 211 and is slidably connected to the inner cavity of the T-shaped groove 211.

[0034] like Figure 3 and 4 As shown, the arc plate 41, spring 42 and damper 43 enter the inner cavity of the tube body 1, and the arc plate 41 is released from contact with the tube body 1, thereby buffering and canceling the vibration of the tube body 1 to achieve vibration reduction. When the arc plate 41 is subjected to force and moves, the arc plate 41 will drive the T-shaped block 411 to slide along the inner cavity of the T-shaped groove 211, thereby limiting the arc plate 41 and ensuring the stability of the arc plate 41 during movement, preventing misalignment.

[0035] In use, first remove the cover 21 and align it with the tube body 1. Then rotate the cover 21, which drives the threaded ring 23 to rotate. During rotation, the tube body 1 and the threaded ring 23 will be threadedly connected, and the tube body 1 will enter the inner cavity of the cover 21 and contact the sealing ring 22. The sealing ring 22 seals the tube body 1 to ensure its airtightness. At the same time, the cover 21 will drive the collar 31 and friction pad 32 to be fitted onto the surface of the tube body 1, and the buffer 4 will enter the interior of the tube body 1. Thus, during vibration, the friction pad 32 increases the friction. The frictional force in contact with the tube body 1 prevents the connection from shaking and coming loose. At the same time, the tube body 1 transmits the vibration force to the arc plate 41. The arc plate 41 moves to one side under the force, which in turn pressurizes the spring 42 and the damper 43, causing the spring 42 and the damper 43 to deform. The deformation force of the spring 42 and the damper 43 buffers the vibration force, while the restoring force of the spring 42 and the damper 43 cancels out the vibration force. This achieves vibration reduction and prevents gaps caused by vibration from affecting the sealing performance.
