Description

Technical Field

[0001] The utility model relates to the technical field of automobile roof linings, in particular to an extended fixing structure for automobile roof linings. Background Art

[0002] The car roof lining is a decoration needed for convertible cars or convertible cars that you modify yourself. It mainly provides a seal and rainproof function for the car, and can also serve as a decoration for the car.

[0003] A currently used extended fixing structure for a car roof lining has been searched and found, for example, in a Chinese patent document with an authorization publication number of CN216002447U, which discloses a car roof lining installation and fixing structure, including a roof lining plate, a support assembly is fixedly installed on the middle part of the upper end of the roof lining plate, a fixing mechanism is symmetrically fixedly installed on the upper end of the support assembly, the support assembly includes a support plate, a groove is opened at the right end of the support plate, a support column is fixedly installed on the front and rear side walls inside the groove, a protrusion is rotatably installed on the outer surface of the support column, and a bracket is fixedly installed on the right end of the protrusion. Through the set fixing mechanism and card plate assembly, it is convenient for users to install and use, and it is easy to operate and also convenient for users to disassemble and replace, which can not only reduce a lot of installation time for users but also improve the installation efficiency of operators, and can not only increase the stability of the entire fixed structure but also increase the practicality of the entire device.

[0004] Although the above patents solve the problems in the above background technology, they still have the following shortcomings: 1.

[0028] For examples, see Figure 1-4 , the utility model provides a technical solution:

[0029] An extended fixing structure for a car roof lining comprises a roof lining plate 1 and a welding frame 2 arranged on the top of the roof lining plate 1, wherein a first fixing strip 101 and a second fixing strip 102 are respectively installed on the top surface of the roof lining plate 1, a fastening seat 103 is respectively fixedly installed on the top surface of the first fixing strip 101 and the second fixing strip 102, a fastening hole 1031 is opened on the top surface of the fastening seat 103, an extension mechanism 3 is arranged between the first fixing strip 101 and the second fixing strip 102, and a fastener 201 is arranged at the bottom of the welding frame 2;

[0030] Specifically, the first fixing strip 101 and the second fixing strip 102 are respectively located at the front and rear ends of the top of the top lining plate 1, and the fastener 201 is rotatably connected to the bottom surface of the welding frame 2 through a rotating shaft. The outer top surface of the fastener 201 is anti-slip, and the outer bottom surface thereof is provided with an external thread groove, and the inner wall of the fastening hole 1031 is provided with an internal thread groove that is screwed with the external thread groove;

[0031] In this embodiment, the fastener 201 is mainly used to contact the fastening hole 1031, thereby achieving the purpose of installing the fastening seat 103, and the No. 1 fixing strip 101 and the No. 2 fixing strip 102 can support the top lining plate 1, meeting the fixing requirements of the top lining plate 1.

[0032] In this embodiment, please refer to Figure 1 and Figure 4The extension mechanism 3 includes a mounting support 301, a square groove 302 and an extension bar 303. The mounting support 301 is fixedly mounted on the top surface of the No. 1 fixing bar 101, and a compression spring 304 is embedded and movably mounted on the top surface thereof. A locking rod 305 is matched and arranged inside the compression spring 304. A pull ring 306 is fixedly mounted on the top of the locking rod 305. The square groove 302 is arranged on the right side surface of the No. 1 fixing bar 101. The extension bar 303 is fixedly arranged on the left side of the No. 2 fixing bar 102, and a plurality of locking holes 307 are respectively arranged on the top surface thereof.

[0033] Specifically, the vertical cross-section of the extension bar 303 is a square structure, and its outer surface is in close contact with the inner wall of the square groove 302, and a plurality of locking holes 307 are equidistantly distributed on the top surface of the extension bar 303. The bottom end of the compression spring 304 is fixedly connected to the bottom inner wall of the mounting bracket 301, and its top end is welded to the bottom surface of the pull ring 306. The bottom end of the locking rod 305 is movable through the bottom inner wall of the mounting bracket 301 and the top surface of the first fixing bar 101 in sequence and extends to the inside of the square groove 302, and is engaged with the locking hole 307.

[0034] In the present embodiment, the extension bar 303 is mainly used for sliding contact with the inner wall of the square groove 302, and the pull ring 306 is mainly used for driving the locking rod 305 and stretching the compression spring 304, so that the locking rod 305 is disengaged from the locking hole 307. In the absence of external force, the compression spring 304 in the stretched state will drive the pull ring 306 and the locking rod 305 to move downward, thereby realizing the connection between the locking rod 305 and the locking hole 307, ensuring the fastening state between the extension bar 303 and the square groove 302, thereby achieving the effect of adjusting the distance between the No. 1 fixing bar 101 and the No. 2 fixing bar 102, and meeting the support requirements of top lining plates 1 of different sizes.

[0035] The working process of the utility model is as follows: when using an extended fixing structure for a car roof lining, the positions of the first fixing strip 101 and the second fixing strip 102 are adjusted according to the size of the roof lining plate 1, and an external force is applied to the pull ring 306, which drives the locking rod 305 to move upward and stretches the compression spring 304 until the locking rod 305 is disengaged from the locking hole 307, and then the extension strip 303 is moved along the inner wall of the square groove 302 until the second fixing strip 102 moves to a suitable position. The external force can be removed, and under the action of the compression spring 304, the locking rod 305 gradually moves down and contacts the locking hole 307, so that the length adjustment of the No. 1 fixing strip 101 and the No. 2 fixing strip 102 can be achieved, and then the adjusted No. 1 fixing strip 101 and the No. 2 fixing strip 102 are fixed to the front and rear ends of the top of the top lining plate 1, and finally the top lining plate 1 is moved to make the fastening hole 1031 close to the fastener 201 and screw them together, thereby completing the fixed installation of the top lining plate 1 and meeting the needs of the user.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
