AI Technical Summary
目前汽车隔热罩大多通过卡扣结构固定安装在车上，但是现有的卡扣结构大多都是通过弹性件的卡合来固定，所以连接的效果较差，在风力较大时，空气会进入汽车隔热罩与挡风玻璃之间，使汽车隔热罩鼓起晃动，进而容易出现卡扣松脱的情况，从而不利于使用，故而提出一种防偏移的隔热罩固定卡扣结构
[0011]有益效果：与现有技术相比，本实用新型的卡扣结构通过将吸盘吸附在车身玻璃上，并将连接块的顶部与隔热罩固定连接，当需要对隔热罩进行安装时，将连接块插入至连接槽的内部，然后便可拧动旋钮来带动转轴和驱动锥齿轮旋转，进而通过从动锥齿轮来带动螺纹杆旋转，而螺纹杆在旋转的过程中则会带动定位块向右移动，来使定位块移动至定位槽的内部，从而对连接块进行卡合固定，当限位槽移动至限位块的正上方时，在限位弹簧的弹力作用下则会带动滑块和限位块向上移动，来使限位块移动至限位槽的内部，从而对定位块进行限位固定，即完成对隔热罩的固定作业，通过设置第一矩形块和连接块为连接媒介来对隔热罩进行安装，强度高，不易变形，进而使隔热罩不会出现偏移的情况，其次，通过定位块来进行卡合固定，固定效果好，不会出现松脱的情况，进而有利于使用。

Description
Technical Field
[0001] This utility model relates to the field of automotive heat shield technology, specifically to a heat shield fixing buckle structure that prevents displacement. Background Technology
[0002] Car heat shields, also known as car sunshades, are used to reduce the temperature inside a car in the short term because sunlight can cause significant damage to leather seats, dashboards, and other interior features.
[0003] In the process of realizing this utility model, the inventors discovered that: Currently, most automotive heat shields are fixed to vehicles using a snap-fit structure. However, existing snap-fit structures mostly rely on the engagement of elastic components, resulting in poor connection. In strong winds, air can enter between the heat shield and the windshield, causing the heat shield to bulge and shake, which can easily lead to the snaps coming loose and hindering its use. Therefore, a heat shield fixing snap-fit structure that prevents displacement is proposed. Summary of the Invention
[0004] In order to solve the problems existing in the prior art, this utility model provides a heat insulation cover fixing buckle structure that prevents displacement, which has the advantages of good fixing effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat insulation cover fixing buckle structure for preventing displacement, comprising a first rectangular block, a suction cup at the bottom of the first rectangular block, a connecting groove at the top of the first rectangular block, a connecting block extending to the top of the first rectangular block at one end inside the connecting groove, a second rectangular block at the left side of the first rectangular block, a rectangular groove at the right side of the second rectangular block, a threaded rod at the left side of the inner wall of the rectangular groove, a through hole at the right side of the threaded rod at the left side of the first rectangular block, a positioning block at one end threaded to the outside of the threaded rod and extending into the through hole at the inside of the rectangular groove, a positioning groove at the right side of the positioning block at the left side of the connecting block, a rotating component at one end extending into the rectangular groove and fixedly connected to the outside of the threaded rod at the bottom left side of the second rectangular block, a limiting groove at the bottom left side of the positioning block, and a limiting component at one end extending into the rectangular groove and fitting against the bottom of the positioning block at the bottom right side of the second rectangular block.
[0006] Preferably, the rotating assembly includes a rotating shaft, a rotating shaft extending into the rectangular groove at one end is movably mounted on the bottom left side of the second rectangular block, a driving bevel gear located below the threaded rod is fixedly mounted on the top of the rotating shaft, a driven bevel gear located on the left side of the positioning block and meshing with the driving bevel gear at one end is fixedly mounted on the outside of the threaded rod, and a knob is fixedly mounted on the bottom of the rotating shaft.
[0007] Preferably, the limiting component includes a housing, a housing is fixedly installed on the bottom right side of the second rectangular block, a slider is movably installed inside the housing, a limiting block is fixedly installed on the top of the slider with one end extending into the rectangular groove and fitting against the bottom right side of the positioning block, a pull rod is fixedly installed on the bottom of the slider with one end extending to the bottom of the housing, a limiting spring located outside the pull rod is fixedly installed between the bottom of the slider and the inner bottom wall of the housing, and a pull ring is fixedly installed on the bottom of the pull rod.
[0008] Preferably, a first bearing is fixedly installed on the left side of the inner wall of the rectangular groove, and the threaded rod is rotatably connected to the left side of the inner wall of the rectangular groove through the first bearing.

[0011] Beneficial effects: Compared with the prior art, the snap-fit structure of this utility model uses a suction cup to adhere to the vehicle glass and fixes the top of the connecting block to the heat insulation cover. When the heat insulation cover needs to be installed, the connecting block is inserted into the connecting groove, and then the knob can be turned to drive the rotating shaft and drive the bevel gear to rotate. In turn, the driven bevel gear drives the threaded rod to rotate. During the rotation of the threaded rod, it will drive the positioning block to move to the right, so that the positioning block moves into the positioning groove, thereby locking and fixing the connecting block. When the limiting groove moves to the top of the limiting block, the elastic force of the limiting spring will drive the slider and the limiting block to move upward, so that the limiting block moves into the limiting groove, thereby limiting and fixing the positioning block, thus completing the fixing operation of the heat insulation cover. By setting the first rectangular block and the connecting block as the connecting medium to install the heat insulation cover, the strength is high and it is not easy to deform, so that the heat insulation cover will not shift. Secondly, the locking and fixing by the positioning block has a good fixing effect and will not loosen, which is beneficial to use. Attached Figure Description

[0017] The working principle of this utility model: In use, first attach the suction cup 2 to the car window and fix the top of the connecting block 4 to the heat insulation cover. When the heat insulation cover needs to be installed, insert the connecting block 4 into the connecting groove 3. Then, turn the knob 114 to drive the rotating shaft 111 and the drive bevel gear 112 to rotate, which in turn drives the threaded rod 7 to rotate through the driven bevel gear 113. During the rotation of the threaded rod 7, the positioning block 9 will move to the right, so that the positioning block 9 moves into the positioning groove 10, thereby locking and fixing the connecting block 4. When the limiting groove 12 moves to the top of the limiting block 133, the elastic force of the limiting spring 135 will drive the slider 132 and the limiting block 133 to move upward, thereby limiting the position. Block 133 moves into the interior of the limiting groove 12, thereby limiting and fixing the positioning block 9, thus completing the fixing operation of the heat insulation cover. The heat insulation cover is installed by setting the first rectangular block 1 and the connecting block 4 as the connecting medium. It has high strength and is not easy to deform, so the heat insulation cover will not shift. Secondly, the positioning block 9 is used for snap-fit fixing, which has a good fixing effect and will not loosen. This is beneficial to use and solves the problem that most existing buckle structures are fixed by snap-fitting elastic elements, so the connection effect is poor. When the wind is strong, air will enter between the car heat insulation cover and the windshield, causing the car heat insulation cover to bulge and shake, which can easily cause the buckle to loosen, thus making it unsuitable for use.
