Description

Technical Field

[0001] The utility model relates to the field of automobile expansion boxes, in particular to a cover structure of an expansion box. Background Art

[0002] The expansion tank is a very important component in the automobile cooling system. In order to prevent the cover of the expansion tank from loosening or even falling off during the various bumpy driving of the automobile, various clip anti-detachment assembly structures have been developed to prevent the expansion tank cover from falling off. At the same time, in order to provide more user-friendly operation, the cover is designed to be easy to tighten and difficult to withdraw and loosen, and more and more designs have emerged, for example, the cover structure of the expansion tank.

[0003] Patent CN207788837U discloses an expansion tank cover tightening tool sleeve, including a cylinder cover and an annular cylinder wall, the cylinder cover and the cylinder wall are fixedly connected or integrally formed, a matching groove is provided on the cylinder cover, and at least two protrusions are provided on the inner wall of the cylinder wall, the matching groove is plugged into the sleeve of a fixed torque electric tightening tool, and the protrusions are releasably offset against the depression on the outer wall of the expansion tank cover. The utility model reduces assembly time, improves employee assembly efficiency, reduces the occurrence of the problem of the expansion tank cover being too tight or too loose after assembly, and improves assembly ergonomics.

[0004] At present, after the traditional automobile expansion tank cap is tightened, the car will inevitably experience bumps when driving. As the car vibrates during long-term operation, most conventional caps do not have positioning buckles, and the caps will become loose or even fall off, which not only causes damage to the vehicle, but also greatly threatens the safety of the people in the car and is inconvenient to use.

[0015] 1. By setting the anti-drop assembly, when the cover of the expansion tank needs to be tightly closed, the cover shell is rotated downward to cover the cover support, and it is rotated until the arc block is close to the bottom of the cover support, so that the block is inserted into the slot. Due to the limitation of the square block, the cover shell will not be easily loosened due to bumps, which greatly improves the practicality of the device.

[0016] 2. By setting up auxiliary components, when the expansion tank cover is closed tightly, the installation clip can be put on the outside of the cover shell, and the nut can be rotated so that the nut can slide left and right on the threaded rod, which is convenient for adjusting the tightness of the installation clip. The installation clip can be used to reinforce the cover shell for the second time. If the cover shell needs to be removed, the cover shell can be rotated by the installation rod, which greatly improves the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] An embodiment of the utility model provides a cover structure of an expansion box.

[0024] See also Figure 1 , Figure 2 and Figure 3 The middle part of the lower end of the cover shell 1 is threadedly connected with the cover support 2, the lower end of the cover shell 1 is provided with an anti-slip assembly, and the upper end of the cover support 2 is provided with an auxiliary assembly, the anti-slip assembly includes an arc clamping block 311, the lower end of the cover shell 1 is fixedly connected with an arc clamping block 311, the lower end of the cover shell 1 is fixedly connected with a square clamping block 312, the lower end of the cover support 2 is fixedly connected with a clamping block 313, the clamping block 313 is clamped at the lower end of the cover shell 1, and the lower end of the cover shell 1 is provided with a clamping groove 314 that cooperates with the clamping block 313, the anti-slip assembly also includes a slide groove 315, and the lower end of the cover support 2 is provided with a slide groove 315.

[0025] When the utility model is in use: before the vehicle drives, the cover of the expansion tank needs to be tightly closed, and the cover shell 1 is covered on the upper end of the cover support 2. The cover shell 1 can be slid up and down by rotating the cover shell 1. When the cover shell 1 slides downward, the cover shell 1 can be closed tightly, and the cover shell 1 is rotated until it is close to the bottom of the cover support 2, so that the block 313 is stuck in the slot 314. Due to the limitation of the arc block 311 and the square block 312, the block 313 is stuck between the two, so that the cover shell 1 will not be easily loosened due to bumps, which greatly improves the practicability of the device.

[0026] Please refer again Figure 1 and Figure 4The auxiliary component includes a mounting clip 411. Two groups of mounting clips 411 are arranged on the outer side of the cover 2. The front and rear ends of the mounting clips 411 are fixedly connected with mounting blocks 412. The middle parts of the two groups of mounting blocks 412 are threadedly connected with the same threaded rod 413. The middle part of the mounting block 412 is provided with a threaded hole that cooperates with the threaded rod 413. The left and right sides of the threaded rod 413 are fixedly connected with a stop block 414. The outer side of the threaded rod 413 is threadedly connected with a nut 415. The auxiliary component also includes a mounting rod 416. The outer sides of the two groups of mounting clips 411 are fixedly connected with the mounting rod 416.

[0027] When the utility model is in use: after the expansion tank cover is closed tightly, the mounting clip 411 can be sleeved on the outside of the cover shell 1, and the nut 415 can be rotated so that the nut 415 can slide left and right on the threaded rod 413, which is convenient for adjusting the tightness of the mounting clip 411. When the nut 415 slides to the left, the mounting clip 411 can be tightened, so that the mounting clip 411 can perform secondary reinforcement on the cover shell 1, which is safer. When the nut 415 slides to the right, the mounting clip 411 can gradually loosen the cover shell 1, which is convenient for removing the cover shell 1. If the cover shell 1 needs to be removed, the cover shell 1 can be rotated by rotating the mounting rod 416, which greatly improves the practicality of the device.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
