[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0020] Please see Figure 1A positioning device for automotive air conditioning components includes a car body 2 with a housing 1, a positioning cylinder 3 on the housing 1, and a hexagonal bolt 4 connected to the car body 2 inside the positioning cylinder 3. A limiting component is fitted onto the bolt 4. By adding a limiting component to the bolt 4 to cooperate with the positioning cylinder 3, the limiting component wraps around the hexagonal bolt 4. The hexagonal bolt 4 is a fixed type of bolt 4 with the same hexagonal head size, which can reduce production costs. At the same time, the limiting component wraps around the head of the bolt 4, and the bolt 4 can be unscrewed by rotating the limiting component. The limiting component can only be opened with the matching tools, which prevents the air conditioning components from being replaced without the user's knowledge during vehicle repair, avoiding property damage. It also prevents the replacement of non-original parts, reducing the losses caused by piracy to the enterprise.

[0021] It also includes a screwdriver 6 for opening the restraints; the restraints can only be opened with the dedicated screwdriver 6.

[0022] The limiting component is a bolt head 5 fitted onto a hexagonal bolt 4. The bolt head 5 is provided with a cross-shaped insert 14, and the end of the screwdriver 6 is provided with a groove 15 that mates with the insert 14. The screwdriver 6 drives the bolt head 5 to rotate through the cooperation of the insert 14 and the groove 15.

[0023] The diameter of the bolt head 5 is the same as the inner diameter of the positioning cylinder 3, and the diameter of the screwdriver 6 is the same as the inner diameter of the positioning cylinder 3. The width of the screwdriver 6 is limited by the inner diameter of the positioning cylinder 3. When the width of the screwdriver 6 is greater than the inner diameter of the positioning cylinder 3, the screwdriver 6 cannot be inserted into the positioning cylinder 3 and the bolt head 5 cannot be unscrewed normally.

[0024] A push block 7 is inserted into the positioning cylinder 3, with one end of the push block 7 located inside the positioning cylinder 3. The push block 7 restricts the bolt head 5. When the push block 7 is not completely pushed out of the positioning cylinder 3, the bolt head 5 cannot be disengaged from the positioning cylinder 3. When the tool diameter is smaller than the inner diameter of the positioning cylinder 3, the tool cannot push the push block 7 out of the positioning cylinder 3, thus playing a restrictive role and preventing the bolt head 5 from being unable to be unscrewed when using non-standard tools.

[0025] The push block 7 has an inclined surface at one end inside the positioning cylinder 3. When the bolt head 5 and screwdriver 6 are inserted into the positioning cylinder 3, the bolt head 5 and screwdriver 6 can push the push block 7 away from the center of the positioning cylinder 3 along the inclined surface, which makes it easy to insert the bolt 4 and bolt head 5, and also easy to insert the screwdriver 6. At the same time, the surface of the push block 7 is still flat, so when the bolt head 5 is unscrewed, the bolt head 5 cannot actively push the push block 7, avoiding the risk of using a tool with a smaller diameter to unscrew it.

[0026] The positioning cylinder 3 has an outer shell 8 on its outer side, and an ejector spring 9 is provided between the push block 7 and the outer shell 8; this facilitates the reset of the push block 7 and allows for repeated use.

[0027] The push block 7 is provided with a baffle 10, which is located outside the positioning cylinder 3. The baffle 10 limits the length of the push block 7 into the positioning cylinder 3, prevents the flat part of the push block 7 from entering the positioning cylinder 3, and prevents the screwdriver 6 and the bolt head 5 from entering the positioning cylinder 3 and failing to push the push block 7 smoothly.

[0028] The body shell 2 is provided with a threaded sleeve 11 that mates with the bolt 4. The positioning cylinder 3 is fitted on the outside of the threaded sleeve 11, and the positioning cylinder 3 is provided with an annular plate 12. The bolt 4 mates with the threaded sleeve 11 and the annular plate 12, and the head of the bolt 4 abuts against the annular plate 12, which can fix the positioning cylinder 3 on the threaded sleeve 11 to achieve the purpose of fixing.

[0029] The positioning cylinder 3 is provided with a circumferentially arranged elastic plate 13; the elastic plate 13 is used to achieve the positioning of positioning cylinders 3 of different widths and threaded sleeves 11. The end of the elastic plate 13 abuts against the outside of the threaded sleeve 11, so as to achieve the alignment of the axis of the positioning cylinder 3 and the axis of the threaded sleeve 11.

[0030] Working principle: During installation, the positioning cylinder 3 is fitted onto the threaded sleeve 11. The end of the elastic plate 13 inside the positioning cylinder 3 abuts against the threaded sleeve 11. Since the elastic plate 13 is circumferentially arranged, the axis of the positioning cylinder 3 can be aligned with the axis of the threaded sleeve 11, which facilitates the subsequent installation of the bolt 4. Then, the bolt 4 is inserted into the threaded sleeve 11 through the ring plate 12. Then, a special screwdriver 6 is used. The groove 15 of the screwdriver head cooperates with the insert 14 on the bolt head 5 to screw the bolt 4 into the threaded sleeve 11. The head of the bolt 4 fixes the ring plate 12 inside the positioning cylinder 3 onto the threaded sleeve 11, achieving the purpose of fixed installation. At the same time, when screwing in the bolt 4 and the bolt head 5, as the bolt head 5 descends, the edge of the bolt head 5 abuts against the inclined surface of the push block 7, which can push the push block 7 outward from the positioning cylinder 3 without affecting the normal installation of the bolt 4. When disassembling the housing 1, a special screwdriver 6 is inserted into the positioning cylinder 3. The head of the screwdriver 6 abuts against the inclined surface of the push block 7, pushing the push block 7 out of the positioning cylinder 3. The end of the push block 7 abuts against the side of the screwdriver 6 and cannot enter the positioning cylinder 3. Then, the bolt head 5 is rotated to remove the bolt 4 from the threaded sleeve 11. Throughout the process, since the screwdriver 6 and the bolt head 5 are both in contact with the inner wall of the positioning cylinder 3, the push block 7 cannot enter the positioning cylinder 3 and will not block the bolt head 5, so the bolt 4 can be unscrewed normally. When the tool diameter is too large, the tool cannot be smoothly inserted into the positioning cylinder 3, and when the tool diameter is too small, the tool cannot push the push block 7 out of the positioning cylinder 3. When rotating the bolt 4, the bolt head 5 will be blocked by the push block 7 and cannot be smoothly removed.

[0031] The technical effect of this utility model is as follows: by adding a limiting part to the bolt 4 to cooperate with the positioning cylinder 3, the limiting part can only be opened with the matching tool, which prevents the air conditioning parts from being replaced without the user's knowledge during vehicle maintenance, thus avoiding property damage. It also prevents the replacement of non-original parts and reduces the losses caused by piracy to enterprises.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
