Referring to fig. 1-4, a vehicle door with a built-in anti-theft lock includes: the door panel unit, the lock lever fixing seat unit, the right door upright post 8 and the internal thread connecting body 9 are arranged in the door panel unit; the whole lock bar unit is columnar; the lock bar fixing seat unit is fixed on the door panel unit and is provided with a lock bar supporting hole 01 for supporting the lock bar unit; one side of the door panel unit is hinged with the left door upright post 10; a locking lever through hole 02 penetrating through the left door upright post 10 is arranged at the position, opposite to the locking lever supporting hole 01, of the left door upright post; the internal thread connector 9 is fixed on the right door upright post 8, the internal thread connector 9 is provided with an internal thread, and the internal thread is arranged opposite to the lock lever supporting hole 01; one end of the lock lever unit close to the left door upright post 10 is provided with an external thread 42 matched with the internal thread; one end face of the locking bar unit close to the right door upright post 8 is provided with a wrench groove 41 which is formed by sinking and is used for inserting a wrench to screw the locking bar unit to rotate along the axis of the internal thread. Door plant unit is including constituteing left door plant 1 and the right door plant 2 of running from opposite directions the door structure, and lock thick stick fixing base unit includes: the left fixing seat 5, the right fixing seat 6 and the extending stop lever 7; the left fixed seat 5 is fixed on the left door panel 1, and the right fixed seat 6 is fixed on the right door panel 2; one end of the extending stop rod 7 is fixed at one end of the right fixing seat 6 close to the left fixing seat 5, and the other end of the extending stop rod 7 extends to the rear of the left door panel 1 after passing through the splicing seam of the left door panel 1 and the right door panel 2; the lock lever support hole 01 penetrates through the left fixing seat 5 and the right fixing seat 6 simultaneously. The locking lever unit comprises a lever body 3 and a stud 4 which are connected in a welding mode, and external threads 42 are arranged on the outer side wall of the stud 4; the wrench groove 41 is formed on an end surface of the stud 4 close to the left door pillar 10. The cross section of the wrench groove 41 is in a regular hexagon shape or a shape like a Chinese character ' yi ' groove or a shape like a cross ' groove. The female threaded connector 9 is a nut. The vehicle door with the anti-theft built-in lock further comprises a left door upright post 10, one end of a left door panel 1 is hinged to the left door upright post 10, and one end, far away from the stud 4, of the lever main body 3 abuts against the left door upright post 10. The vehicle door with the anti-theft built-in lock further comprises a circular tube-shaped sheath 11, wherein the sheath 11 is arranged in the lock lever through hole 02; the inner diameter of the sheath 11 is larger than the maximum value of the outer diameter of the lock lever unit. This design facilitates insertion and extraction of the lock lever unit. One end of the sheath 11 is flush with the outer side surface of the right door pillar 8. The vehicle door with the anti-theft built-in lock further comprises a cap backing plate 12, wherein the cap backing plate 12 is fixed on the outer side surface of the right door upright post 8 through a threaded connecting piece 13 and completely covers the locking lever hole. The threaded connection members 13 are two and arranged in the height direction of the right door pillar 8.
The vehicle door with the anti-theft built-in lock in the embodiment is arranged on a carriage body, particularly on the rear door of the carriage body, and the lever main body 3 is positioned in the carriage body. The lock bar fixing seat unit is fixed on the back door, after the lock bar unit penetrates through the lock bar supporting hole 01, one end of the stud 4 of the lock bar unit is in threaded connection with the internal thread connector 9, the internal thread connector 9 is fixed on the right door upright post 8, and therefore the lock bar can fix the back door and the right door upright post into a whole. In this state, even if the door lock outside the rear door is opened, the door cannot be opened because the lock lever unit is fixed inside the rear door. In this state, when the door needs to be opened, a wrench needs to be used to extend into the right door pillar 8 from the outside, to be inserted into the lock lever through hole 02, and to extend into the wrench groove 41 on the stud 4. The spanner is rotated to control the stud 4 to rotate, so that the locking bar unit is driven to rotate integrally, the stud 4 rotates and moves towards the direction close to an operator, and when the stud 4 passes through the threaded connecting part 13 in a rotating mode, the locking bar unit can be pulled by hand to be drawn out of the compartment body from the locking bar through hole 02. At the moment, the door panel loses the constraint of the lock lever unit, and can be freely opened under the condition that the external door lock is opened. When the locking lever unit is installed, one end of a non-bolt section of the locking lever unit is inserted into the locking lever through hole 02 first and then continuously inserted into and penetrates through the locking lever supporting hole 01, when the bolt 4 touches the internal thread connector 9, direct insertion cannot be continuously performed, at the moment, the locking lever unit is pulled by a wrench through the wrench groove 41, the bolt 4 is screwed into the internal thread connector 9, and the locking lever can fix the back door and the right door upright post 8 into a whole. In the present embodiment, the sheath 11 serves to prevent damage to the right door pillar 8 when the lock lever unit is repeatedly inserted and withdrawn, and to protect the right door pillar from being damaged. In this embodiment, the cap backing plate 12 is used to cover the lock lever through hole 02, to enhance concealment and prevent a lawless person from finding the position of the lock lever unit. The threaded connection piece 13 is two and the design that is vertical setting for guarantee that the threaded connection piece 13 arranges along the direction of height of stand, do benefit to the firm locking on the stand of threaded connection piece 13. The extending stop lever 7 in the lock lever fixing seat unit has the effect that when the rear door is externally locked on the left door panel 1 only through an electronic lock, and the right door panel 2 is outwards opened, the extending stop lever 7 interferes with the left door panel 1 to limit the outward opening action of the right door panel 2. That is, by providing the extended stop 7, a lock can lock two doors at the same time. The cost of the lockset is saved. In this embodiment, the lock bar fixing unit is made of a profile shaped like "Ω" by cutting and slicing. The hole of the profile itself of the "omega" -like shape can be used directly as the lock bar support hole 01. The design is beneficial to processing and forming and ensures the overall performance. In the present embodiment, the shape of the wrench groove 41 may be the shape of a common wrench groove 41, but in order to increase the anti-theft performance, a special-shaped groove may be provided, so that a corresponding special-shaped wrench is needed to open, thereby improving the anti-theft effect. To reduce costs, the female connector body 9 can be replaced by a standard socket head nut.
In addition, the directions of "left" and "right" referred to in the present invention refer to directions when the rear door of the car is viewed in the car body.
Compared with the prior art, the invention provides the vehicle door with the anti-theft built-in lock, which can be arranged at the rear part of a carriage body and can effectively prevent a lawless person from directly opening the carriage door after opening the rear door lock. The anti-theft performance of the carriage body can be improved.
While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
