Description

Technical Field

[0001] The embodiments of this utility model belong to the field of special vehicle manufacturing technology, and more specifically, relate to a process door lock suitable for armored vehicle doors. Background Technology

[0002] During the production of a certain series of armored vehicles, after the body-in-white is welded and formed, the doors and other opening and closing components need to be installed on the body-in-white before painting. Because the doors and locking mechanisms on the body-in-white are not installed, the doors cannot be closed, which adversely affects the transport and painting of the body-in-white.

[0003] Currently, using process door locks is an effective way to solve such problems. Patent CN206220712U discloses a process door lock for car door painting. One end of the elastic structure is an insertion end that inserts into the door lock pin hole. After the insertion end is bent, an elastic ring is wrapped around it. After the elastic ring, a process ring or handle ring is provided through an extension section, and the process ring or handle ring extends out to provide a connecting end. The insertion end and the connecting end are in the same direction and have the same elasticity as the elastic ring. The connecting end is also fitted with a plastic conical limiting block, and the connecting end extends from the middle of the conical limiting block. Although this patent solves the problem of door closure and painting quality around the pin hole, its use of an elastic structure to connect the car body and the door is prone to deformation under stress during transportation and painting operations, causing gaps between the car body and the door, affecting output operations. Moreover, after long-term use, the process door lock will deform and bend, making it unable to lock the car body and door.

[0004] Therefore, there is an urgent need for a process door lock suitable for armored vehicle doors. It can be installed and locked based on the structure of the body-in-white and the door, making the most of existing structures such as positioning holes and grooves. It is simple to operate, securely locked, and can be used repeatedly for a long time. Summary of the Invention

[0005] In view of the problems of existing process locks being easily deformed by force, causing gaps between the vehicle body and the door, and having a short service life, this utility model provides a process door lock suitable for armored vehicle doors to solve these problems.

[0006] To achieve the above objectives, this utility model provides a process door lock suitable for armored vehicle doors, including a lock body mechanism fixedly installed at a corresponding location on the body-in-white, comprising a mounting plate, a connecting screw, a locking rod, and a limiting component; the connecting screw is vertically fixedly installed on the mounting plate; one end of the locking rod is rotatably connected to the connecting screw; the limiting component abuts against both sides of the locking rod and restricts its rotation; and a lock hook mechanism fixedly installed at a corresponding location on the door, comprising a temporary handle and a limiting groove on the temporary handle, the limiting groove engaging with the other end of the locking rod to lock the door.

[0007] Furthermore, the limiting component includes a first limiting nut and a second limiting nut, which are respectively threaded to the connecting screw and located on both sides of the locking rod.

[0008] Furthermore, the top of the limiting groove is also provided with a horizontal groove to provide reserved space for the other end of the locking rod to rotate.

[0009] Furthermore, the mounting plate is a strip plate, which has a first through hole corresponding to the screw holes on the white body, and a first projection nut is welded and fixed at the first through hole.

[0010] Furthermore, the temporary handle has an arched structure, and a second through hole is opened at the arch foot corresponding to the screw hole on the door. A second projection nut is welded and fixed at the second through hole.

[0011] Furthermore, the locking rod includes a rod body, and a locking part and a connecting part respectively provided at both ends of the rod body; the connecting part has a rotating hole, which is sleeved on the connecting screw, so that the locking rod rotates around the connecting screw; the connecting part is provided with a slot, which cooperates with the locking hook mechanism to lock the door to the body-in-white.

[0012] Furthermore, the width of the limiting groove is adapted to the thickness of the locking rod to limit the horizontal lateral displacement of the locking rod, and the thickness of the temporary handle is adapted to the width of the slot to limit the horizontal longitudinal displacement of the locking rod.

[0013] Furthermore, the connecting part of the locking rod is provided with a surface roughening layer on both sides, which increases the friction between the two sides of the connecting part and the first limiting nut and the second limiting nut respectively, and prevents the locking rod from rotating in the locked state.

[0014] Furthermore, both the lock body mechanism and the lock hook mechanism are made of stainless steel.

[0015] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0016] (1) The process door lock of this utility model is locked by engaging one end of the lock rod with the limiting groove, and the lock body mechanism and the lock hook mechanism are installed by using the screw holes inherent on the white body and the door respectively, thereby simplifying the installation and locking process, making the operation more convenient, and making it easier for technicians to quickly complete the locking work of the door.

[0017] (2) The process door lock of this utility model adopts a rigid structure design, which can ensure that the lock between the door and the body is more secure, effectively preventing the gap between the door and the body from being caused by force during transportation and painting operations, thus improving the stability and safety of the operation.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be 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 for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] like Figure 1-3As shown, this utility model provides a process door lock suitable for armored vehicle doors, including a lock body mechanism 1 fixedly installed at a corresponding location on the body-in-white 2, and a lock hook mechanism 3 fixedly installed at a corresponding location on the door 4. The lock body mechanism 1 includes a mounting plate 11, a connecting screw 12, a locking rod 13, and a limiting component 14. The mounting plate 11 is provided with a first welded nut 11 corresponding to a screw hole on the body-in-white 2. The mounting plate 11 is fixedly installed on the body-in-white 2 at intervals by bolts passing through the first welded nut 11, thereby reducing the contact area between the mounting plate 11 and the body-in-white 4. The connecting screw 12 is vertically fixed on the mounting plate 11. One end of the locking rod 13 is rotatably connected to the connecting screw 12. The limiting component 14 is threadedly connected to the connecting screw 12, abutting against both sides of the locking rod 13 and restricting the rotation of the locking rod 13. The lock hook mechanism 3 includes a temporary handle 301, and a transverse groove 303 and a limiting groove 304 provided on the temporary handle 301. During the locking operation, the car door is closed tightly, and the locking rod 13 is rotated so that its other end engages with the limiting groove 304 to prevent horizontal displacement. The limiting component 14 is then rotated to restrict the vertical displacement of the locking rod 13 and prevent it from rotating, thereby locking the car door 2. This utility model of a door lock uses a rigid structure to lock the car body and the door, is simple to operate, has a good locking effect, and can be used repeatedly for a long time.

[0025] like Figure 2-3 As shown in the embodiment of this utility model, the lock body mechanism 1 is fixedly installed at the corresponding position of the body-in-white 2 and cooperates with the lock hook mechanism 3 to lock the door 4 to the body-in-white 2. It includes a mounting plate 11, a connecting screw 12, a lock rod 13, a limiting component 14 and a first projection weld nut 15.

[0026] The mounting plate 11 is a strip plate with a first through hole corresponding to the screw holes on the white body. A first projection nut 15 is welded and fixed at the first through hole to separate the mounting plate 11 from the white body 2, thereby reducing the contact area between the mounting plate 11 and the white body 2 and increasing the contact area between the white body 2 and the electrophoretic liquid.

[0027] The connecting screw 12 is vertically fixed on the mounting plate 11 and is used to install the connecting locking rod 13 and the limiting component 14.

[0028] The locking rod 13 includes a rod body 131, and locking portions 132 and connecting portions 133 respectively located at both ends of the rod body 131. The connecting portion 133 has a rotating hole and is fitted onto the connecting screw 12, allowing the locking rod 13 to rotate around the connecting screw 12. The connecting portion 133 has a slot that cooperates with the locking hook mechanism 3 to lock the door 4 to the body 2. In this embodiment of the invention, the degree of closure of the door 4 can be adjusted by adjusting the position of the locking rod 13 on the connecting screw 12.

[0029] The limiting component 14 includes a first limiting nut and a second limiting nut 142, both of which are threadedly connected to the connecting screw 12 and are located on both sides of the locking rod 13. By rotating the first limiting nut 141 and the second limiting nut 142, they are made to abut against both sides of the locking rod 13, limiting its lateral displacement and using friction to prevent rotation, thus avoiding the locking rod 13 from rotating and unlocking due to force during the transfer and painting operation. Since the locking rod 13 is mainly subjected to the horizontal tension between the door 4 and the body 2 when it engages with the locking hook mechanism 3, the force it is subjected to in the vertical direction is mainly the weight of the locking rod 13 itself and the impact force generated by vibration during the transfer. The forces of these two are relatively small. The friction force generated by the first limiting nut and the second limiting nut 142 against both sides of the locking rod 13 is much greater than its own weight and the impact force, thereby limiting the rotation of the locking rod 13 and preventing unlocking during the operation.

[0030] Preferably, the connecting portion 133 of the locking rod 13 is provided with a surface roughening layer on both sides, which can increase the friction between the two sides of the connecting portion 133 and the first limiting nut and the second limiting nut 142 respectively, and can effectively prevent the locking rod 13 from rotating in the locked state.

[0031] like Figure 1 As shown, the locking mechanism 3 includes a temporary handle 301, a second projection weld nut 302, a transverse groove 303, and a limiting groove 304. The temporary handle 301 has an arched structure, and a second through hole is opened at the arch foot corresponding to the screw hole on the car door 4. A second projection weld nut 15 is welded and fixed at the second through hole. The second projection weld nut 302 can separate the temporary handle 301 from the car door 4, thereby reducing the contact area between the temporary handle 301 and the car door 4 and increasing the contact area between the car door 4 and the electrophoretic liquid. The transverse groove 303 is provided on one side of the arch top of the temporary handle 301, and a limiting groove 304 is opened at its bottom. The transverse groove 303 provides reserved space for the locking part 132 of the locking rod 13 to rotate, so that the locking part 132 rotates into the transverse groove 303 and engages with the limiting groove 304. The width of the limiting groove 304 is adapted to the thickness of the locking rod 13, thus limiting the horizontal lateral displacement of the locking rod 13. The thickness of the temporary handle 301 is adapted to the width of the slot, thus limiting the horizontal longitudinal displacement of the locking rod 13.

[0032] In this embodiment of the utility model, both the lock body mechanism 1 and the lock hook mechanism 3 are made of stainless steel. Their surfaces have low paint adhesion, which can prevent the paint layer from piling up too thickly during repeated use and affecting the use. In addition, they are strong, corrosion resistant, and can be used repeatedly for a long time.

[0033] In this embodiment of the present invention, the bottom of the first projection weld nut 15 and the second projection weld nut 302 is a conical structure, which further reduces the contact area with the body-in-white 2 or the door 4 and increases the contact area between the body-in-white 2 and the door 4 and the electrophoretic liquid.

[0034] In this utility model of a process door lock, during locking operations, the lock body mechanism 1 is installed at the corresponding position on the white body 2, and the lock hook mechanism 3 is installed at the corresponding position on the door 4; the door 4 is closed, and the lock rod 13 is moved to the corresponding position along the connecting screw 12, so that the lock rod 13 is aligned with the limiting groove 304; the lock rod 13 is rotated so that the slot engages with the limiting groove 304; the first limiting nut 141 and the second limiting nut 142 are rotated so that they respectively abut against the two sides of the lock rod 13, restricting its lateral movement, thereby locking the door 4 to the white body 2; after the painting operation is completed, the first limiting nut 141 and the second limiting nut 142 are rotated in the opposite direction so that they disengage from the two sides of the lock rod 13, and the lock rod 13 is rotated upward so that it disengages from the lock hook mechanism 3; thus completing the unlocking operation; the lock body mechanism 1 and the lock hook mechanism 3 are disassembled, and the next round of locking operations is carried out.

[0035] The process door lock of this utility model is locked by one end of the locking rod 13 engaging with the limiting groove 304, which simplifies the installation and locking process, makes the operation more convenient, and makes it easier for technicians to quickly complete the locking work of the car door.

[0036] The process door lock of this utility model adopts a rigid structure design, which can ensure a more secure lock between the door 4 and the body 2, effectively preventing gaps between the door and the body due to stress during transportation and painting operations, thus improving the stability and safety of the operation.

[0037] The door lock of this utility model takes into account the needs of long-term use. Through reasonable structural design and material selection, the door lock can withstand repeated use without deformation or damage, thereby achieving long-term cyclic use and reducing maintenance costs and replacement frequency.

[0038] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
