DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0024] like Figure 1-3 As shown, an embodiment of the present invention provides a door lock for an off-road vehicle, comprising a door lock body 1, a mounting bolt 2, a first limiting nut 3, and a locking bolt 6. The door lock body 1 includes a transition plate 11, and a mounting plate 12 and a locking plate 13, respectively disposed at either end of the transition plate 11. The mounting plate 12 is provided with a rotation hole 121, and the locking plate 13 is provided with a locking groove 131. The mounting bolt 2 passes through the rotation hole 121 and is threadedly connected to a first mounting hole 801 on the vehicle body 8. The first limiting nut 3 is threadedly connected to the mounting bolt 2, separating the door lock body 1 from the vehicle body 8 and restricting the door lock body 1 from sliding axially along the mounting bolt 2, so that the door lock body 1 can only rotate radially about the mounting bolt 2. The locking bolt 6 is threadedly connected to a third mounting hole on the vehicle door 9. To lock the vehicle, the locking plate 13 is moved upward, causing the door lock body 1 to rotate within a certain range around the mounting bolt 2. The vehicle door is then closed, and the locking plate 13 is rotated downward, aligning the sliding groove 122 with the locking bolt 6. The locking plate 13 then slides downward, allowing the locking bolt 6 to slide into the bottom of the sliding groove 122, locking the vehicle. This locking plate solves the problem of paint damage to the vehicle body and makes locking and opening the vehicle door simpler and more convenient, improving operational efficiency.
[0025] like Figure 1 As shown, the door lock body 1 is an I-shaped structure, including a transition plate 11, and a mounting plate 12 and a locking plate 13 respectively provided at both ends of the transition plate 11.
[0026] The transition plate 11 adjusts the distance between the mounting plate 12 and the locking plate 13 so that the door lock body 1 fits the gap between the vehicle body 8 and the door 9, and extends the locking plate 13 to the corresponding position of the door 9 so that the door 9 can be effectively locked after closing.
[0027] The mounting plate 12 is used for rotational connection with the vehicle body 8, and a rotation hole 121 is opened at the corresponding position on it. The mounting bolt 2 passes through the rotation hole 121 and is threadedly connected to the first mounting hole, thereby realizing the installation of the door lock body 1 on the vehicle body 8; further, in order to realize the limited rotation of the door lock body 1 and at the same time avoid the excessive contact area between the door lock body 1 and the vehicle body 8 to reduce the painting effect, a first limiting nut 3 is also provided between the door lock body 1 and the vehicle body 8. The first limiting nut 3 is threadedly connected to the mounting bolt 2, and the distance between the first limiting nut 3 and the head of the mounting bolt 2 is adapted to the thickness of the door lock body 1, thereby limiting the axial sliding of the door lock body 1 along the mounting bolt 2 and causing the door lock body 1 to rotate radially around the mounting bolt 2. Furthermore, to limit the rotational travel of the door lock body 1 and prevent collision with the vehicle body 8 and paint peeling, the mounting plate 12 is further provided with a sliding groove 122, which is located below the rotation hole 121 and corresponds to the second mounting hole 802 on the vehicle body 8. The limiting bolt 4 passes through the sliding groove 122 and is threadedly connected to the second mounting hole 802. When the door lock body 1 is rotated, the limiting bolt 4 contacts the ends of the sliding groove 122, thereby limiting the rotational travel of the door lock body 1 and preventing collision with the vehicle body 8. Preferably, a second limiting nut 5 is further provided between the sliding groove 122 and the vehicle body 8. The second limiting nut 5 is threadedly connected to the limiting bolt 4. The spacing between the second limiting nut 5 and the head of the limiting bolt 4 is adapted to the thickness of the door lock body 1. This can prevent the end of the mounting plate 12 farther from the rotation hole 121 from swinging due to force, thereby making the door lock body 1 rotate more smoothly. Preferably, the mounting plate 12 is also provided with a weight-reducing hole 123 and a weight-reducing groove 124, both of which effectively reduce the overall weight of the door lock body 1, and can serve as backups for the rotating hole 121 and the sliding groove 122 respectively, and are used to install the door lock body 1 on different types of vehicles, so as to adapt to other vehicle models for locking operations.
[0028] The locking plate 13 is used to lock the vehicle door 9, and a locking slide groove 131 is provided at the corresponding position thereon. The width of the locking slide groove 131 is the same as that of the locking bolt 6, and it includes a vertical groove provided at the bottom of the vertical groove; preferably, an arc-shaped chamfer is provided on the outer side of the vertical groove; the circular outer periphery of the locking bolt 6 is tangent to the arc-shaped chamfer, and a tangential force is generated so that the locking bolt 6 can slide smoothly into the arc-shaped groove and slide along the arc-shaped groove to the lower end of the vertical groove, releasing the door lock body 1, so that the locking plate 13 falls naturally under the action of gravity, and the locking bolt 6 is blocked from falling by contacting with the vertical groove, and the locking bolt 6 is limited by the groove walls on both sides of the vertical groove, thereby completing the locking operation and preventing the vehicle door 9 from opening during the painting process.
[0029] In order to facilitate pushing the door lock body 1 to rotate upward for unlocking, a lever 7 is also provided on the locking plate 13. By lifting the lever 7 upward, the locking plate 13 is rotated upward. After the locking bolt 6 slides to the arc groove, the car door 9 can be opened, and the locking bolt 6 is disengaged from the door lock body 1, completing the unlocking action.
[0030] like Figure 2 As shown, when installing the process door lock, the mounting bolt 2 is passed through the rotating hole 121 and threadedly connected to the first limiting nut 3, and the first limiting nut 3 is rotated to limit the door lock body 1; the limiting bolt 4 is passed through the sliding groove 122 and threadedly connected to the second limiting nut 5, and the second limiting nut 5 is rotated to limit the door lock body 1; the mounting bolt 2 is screwed into the first mounting hole 801, and the limiting bolt 4 is screwed into the second mounting hole 802. After completion, the door lock body 1 is rotated to ensure that it can rotate smoothly and will not slide axially along the mounting bolt 2; the locking bolt 6 is aligned with the third mounting hole and screwed in to connect it to the vehicle door 9; thereby completing the installation operation of the process door lock.
[0031] like Figure 3 As shown, when the locking operation is performed, the vehicle door 9 is pushed toward the vehicle body 8 and closed. The locking bolt 6 is tangent to the arc chamfer provided on the outer side of the vertical groove, and a tangential force is generated so that the locking bolt 6 can slide smoothly into the arc groove and slide along the arc groove to the lower end of the vertical groove, releasing the door lock body 1, so that the locking plate 13 falls naturally under the action of gravity, and the locking bolt 6 is blocked from falling by contacting with the vertical groove, and the locking bolt 6 is limited by the groove walls on both sides of the vertical groove, thereby completing the locking operation and preventing the vehicle door 9 from opening during the painting process.
[0032] When performing the unlocking operation, the lever 7 is lifted upward to rotate the locking plate 13 upward. After the locking bolt 6 slides to the arc groove, the vehicle door 9 can be opened to disengage the locking bolt 6 from the door lock body 1, completing the unlocking operation.
[0033] The craft door lock of the present invention is installed using the existing door lock assembly screw holes of the door 9 and the door frame of the vehicle body 8, and adopts the first limiting nut 3 and the second limiting nut 5 to separate the door lock body 1, thereby solving the problem of the craft door lock damaging the paint of the door frame sealing beam. It is simple to disassemble and assemble, and greatly improves the painting efficiency.
[0034] The craft door lock of the present invention provides an arc-shaped chamfer on the outer side of the vertical groove, so that the locking bolt 6 can slide smoothly into the arc-shaped groove and slide along the arc-shaped groove to the lower end of the vertical groove, and the locking plate 13 falls naturally under the action of gravity, thereby quickly completing the locking operation; when unlocking, it is only necessary to lift the lever 7 upward to rotate the locking plate 13 upward, and the locking bolt 6 can slide to the arc-shaped groove to open the car door 9; thereby, the door locking and opening actions of the craft door lock can be completed simply and quickly.
[0035] The craft door lock of the present invention is made of stainless steel material, and its surface has low adhesion to paint, which can avoid the paint layer from piling up too thickly and affecting its use during multiple uses. It is also strong and corrosion-resistant and can be recycled for a long time.
[0036] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
