[0002] Lock machine refers to the situation that equipment is locked or restricted use, this situation can occur on various equipment, when wheel lock machine, usually pass through rim brake disc, make automobile wheel hub stop rotating, to prevent wheel rotation, play the role of lock machine.

[0003] For example, the announcement number is "CN219686964U", a hub unit central locking mechanism, the 5 or 6 bolt nut fasteners on the flange disc circumference of the inner side of the rim required for installing rim brake disc are changed to 1 bolt nut fastener in the central position of the outer side of the rim, so that the replacement of the rim tire is more rapid and convenient, most locking parts are in the inner side of the tail end of the flange disc, not easy to be eroded by mud, not easy to rust, prolong service life. However, when the rim brake disc needs to be maintained, the end of the bolt is not easy to enter the threaded hole in the flange disc, and the operator needs to consume a long time to replace the rim tire, thereby reducing the work efficiency. UTILITY MODEL CONTENTS

[0004] The utility model aims at solving the problem that when the rim brake disc needs to be maintained, the end of the bolt is not easy to enter the threaded hole in the flange disc, and the operator needs to consume a long time to replace the rim tire, thereby reducing the work efficiency, and provides an automobile lock machine structure.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] An automobile lock machine structure is designed, which comprises a hub unit body and a first flange, the right side of the hub unit body is fixedly connected with the first flange, the inside of the first flange is provided with a fixing mechanism, the right side of the first flange is attached to a second flange, and a rim guide end is installed on the right side of the second flange.

[0007] Preferably, the fixing mechanism comprises a bolt, the end of the bolt is fixedly connected with a circular truncated cone, the circular truncated cone is slidably connected with a conical groove, the outer wall of the bolt is bolted with the first flange and the second flange respectively, the bolt is threadedly connected with a nut, and the inside of the nut is attached to the first flange.

[0008] Preferably, the conical groove is machined on the first flange and the second flange respectively.

[0009] Preferably, the right side of the rim guide end is installed with a rim brake disc.

[0010] The utility model provides a kind of automobile lock machine structure, beneficial effect lies in: by the cooperation of first flange, second flange and fixed mechanism, insert the circular table along conical groove into first flange and second flange, rotate bolt and nut simultaneously, when first flange and second flange inside abut tightly, stop rotating bolt and nut, to realize by conical groove and circular table, bolt is more easily entered into first flange and second flange, and the rim brake disc that needs to be repaired can be installed in shorter time, to improve work efficiency.

[0017] The utility model is further described below in connection with the drawings:

[0018] Refer to the Figures 1-5 : in the embodiment, a kind of automobile lock machine structure, including hub unit body 1 and first flange 2, hub unit body 1 and rim guide end have been disclosed in the announcement number CN219686964U in this paper, here, do not make too much repetition, hub unit body 1 right side fixedly connected with first flange 2, first flange 2 inside is equipped with fixed mechanism 5, first flange 2 right side and second flange 4 are pasted, and second flange 4 right side is equipped with rim guide end 3.

[0019] Fixed mechanism 5 includes bolt 501, bolt 501 end fixedly connected with circular table 502, circular table 502 is slidably connected with conical groove 503, bolt 501 outer wall is bolted with first flange 2 and second flange 4 respectively, bolt 501 is screw-threaded with nut 504, and nut 504 inside and first flange 2 are pasted.

[0020] The taper groove 503 is respectively machined on the first flange 2 and the second flange 4, and the rim brake disc 6 is installed on the right side of the rim guide end.

[0021] Working principle:

[0022] When the automobile lock mechanism structure is used:

[0023] The automobile rim tire is usually braked by the rim brake disc 6 through the rim guide end 3 to make the hub unit body 1, and the purpose of the lock mechanism is achieved, which is a relatively mature prior art, and thus will not be described in detail.

[0024] When the rim brake disc 6 needs to be repaired:

[0025] The operator rotates the nut 504 and the bolt 501 to separate the first flange 2 and the second flange 4, and then the operator repairs the rim brake disc 6, and when the rim brake disc 6 is repaired, the operator inserts the circular table 502 into the first flange 2 and the second flange 4 along the taper groove 503, and rotates the bolt 501 and the nut 504, and when the inner sides of the first flange 2 and the second flange 4 abut tightly, the rotation of the bolt 501 and the nut 504 is stopped, so that the rim brake disc 6 is installed, so that the bolt 501 is more easily inserted into the first flange 2 and the second flange 4, and the repaired rim brake disc 6 can be installed in a shorter time, thereby improving the work efficiency.

[0026] Although the utility model has been illustrated and described by referring to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
