[0002] A car fan sleeve is used to secure the fan at the air outlet of a car's air conditioning system; it is one of the car's accessories.

[0003] For example, the Chinese authorized patent with publication number CN213392821U (A Car Fan Sleeve Structure) includes a fixed tube, an extension tube fixedly installed on the top surface of the fixed tube, a telescopic tube movably connected to the top of the extension tube, a clearance groove on the bottom surface of the telescopic tube, a base plate fixedly installed at the bottom end of the fixed tube, a top plate fixedly installed at the top of the telescopic tube, and an engaging sleeve fixedly installed on the top surface of the base plate. This invention, by rotating a threaded rod and engaging it with the engaging sleeve, allows the threaded rod to extend beyond the top of the engaging sleeve. The top of the extension tube is movably connected to the clearance groove, allowing the telescopic tube to slide on the surface of the extension tube. This changes the distance between the bottom surface of the fixed tube and the top surface of the telescopic tube. During installation, the length of the device can be adjusted to accommodate car fans of different sizes, increasing the device's practicality.

[0004] However, existing automotive fan sealing sleeves are usually fixed to the fan with screws. Disassembly requires tools to remove the screws from inside the sealing sleeve before removing the fan, which is time-consuming and laborious. Furthermore, disassembly inside the sealing sleeve is space-constrained and inconvenient. Therefore, this does not meet the current requirements. To address this, we have proposed a new sealing sleeve. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing sleeve to solve the problems mentioned in the background art, where the sealing sleeve of the existing car fan is usually fixed to the fan with screws. When disassembling, tools are needed to remove the screws inside the sealing sleeve before removing the fan, which is time-consuming and laborious. Furthermore, disassembling inside the sealing sleeve is inconvenient due to limited space.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sealing sleeve, comprising: a sleeve body, wherein a sleeve groove is provided inside the sleeve body, a connecting component is provided inside the sleeve groove, an adjusting component is provided at the lower end of the connecting component, a limiting slot is provided on all four inner walls of the sleeve groove, and the limiting slot extends vertically through the sleeve body, a rotating groove is provided on the inner wall of the sleeve body near the bottom, and a fixing groove is provided on the top surface of the rotating groove, and multiple fixing grooves are provided.

[0007] Preferably, the connecting assembly includes a connecting base, and the outer walls of the connecting base are provided with limiting plates. The upper surface of the limiting plates is provided with fixing strips, and the fixing strips are inserted into fixing grooves. The upper surface of the connecting base is provided with mounting holes.

[0008] Preferably, the connecting assembly further includes a rotating sleeve, and the rotating sleeve is located at the center of the lower surface of the connecting base.

[0009] Preferably, the adjustment assembly includes an adjustment plate, a positioning seat is provided on the central upper surface of the adjustment plate, a ball bearing is provided on the outside of the positioning seat, and a rotating sleeve is sleeved on the outside of the ball bearing, and is rotatably connected to the positioning seat through the ball bearing.

[0010] Preferably, the outer walls of the adjusting plate are provided with stabilizing inserts, and both the stabilizing inserts and the limiting inserts move up and down along the limiting slots. The limiting inserts rotate along the rotating groove via the rotating sleeve.

[0011] Preferably, the adjustment assembly further includes a pressing base, which is located on the lower surface of the adjustment plate. Compression springs are provided at the lower ends of all four sides of the pressing base, and spring seats are provided at both ends of the compression springs.

[0012] Preferably, the bottom surface of the rotating groove is provided with an installation groove, and the spring seat at the lower end of the compression spring is fixed inside the installation groove, and the spring seat at the other end of the compression spring is welded and fixed to the lower surface of the pressing base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a rotating groove on the inner wall near the bottom of the sleeve groove, and sets a connecting component and an adjusting component inside the sleeve groove. The car fan is fixed to the connecting base by external fasteners. The connecting base is inserted along the sleeve groove, rotated and sleeved outside the ball bearing, and continues to press down, which has a pressing effect on the adjusting plate. Relying on the deformation effect of the compression spring, the adjusting plate continues to move down. Then, by rotating the connecting base, the limiting insert plate rotates along the rotating groove until the fixing bar is inserted into the fixing groove by the elastic energy of the compression spring, so that the connecting base is connected to the sleeve body. When it is necessary to disassemble the car fan, it is only necessary to press down the connecting base and then rotate the connecting base to remove the car fan. It is not necessary to use tools to disassemble the car fan inside the sleeve groove. After taking it out, it can be disassembled. The space is large and the disassembly is convenient, which improves the convenience and efficiency of disassembly, saves time and effort, and solves the problem that the existing car fan sealing sleeve is usually fixed to the fan by screws. When disassembling, tools are needed to remove the screws inside the sealing sleeve before removing the fan, which is time-consuming and laborious. In addition, the space is limited and inconvenient to operate when disassembling inside the sealing sleeve.

[0015] (2) By setting limit plates on all four outer walls of the connecting base, the connecting base is inserted into the sleeve groove. When inserted, the limit plates move downward along the limit slot, which improves the stability of movement and avoids the connecting base from rotating and shifting, thus affecting the stability of installation. In addition, stabilizing plates are set on all four outer walls of the adjusting plate. The stabilizing plates move along the limit slot. When the connecting base rotates, the stabilizing plates are squeezed against the limit slot to prevent the adjusting plate from rotating, thereby preventing the compression spring from being damaged by rotational force and improving its service life.
