Description

Technical Field

[0001] The utility model relates to a vehicle door painting tool, in particular to a magnetic door painting limiting process lock. Background Art

[0002] The inventor discovered during the process of implementing the utility model that:

[0003] The utility model patent with announcement number CN105672789A discloses a car door limit process lock. When in use, the middle part of the stop edge of the car body door opening is inserted into the slot, and the fastening bolt outside the slot is rotated to fix the process lock to the stop edge of the door opening. The connecting rod extends above the gap between the inner and outer panels of the car door, and the operating handle is pushed backward to achieve door limit or limit release.

[0004] However, this utility model has at least the following problems in actual use: First, manual contact and manual operation are required to open the car door for subsequent painting of the inside of the car door; second, one end of its installation part is on the edge of the stop of the car body door opening, and the other end extends above the gap between the inner and outer panels of the car door. This position is just above the lower edge of the car door window. Since the process lock has paint residue on the surface after long-term use, the paint residue is easy to fall onto the surface of the car door after using the process lock, affecting the quality of the topcoat, resulting in rework, increased production costs, and reduced work efficiency; third, the stop edge of the sealing strip for installing the sealing strip may shake due to the possibility of shaking of the car door, causing the clamping head to swing and deform, and thus there is a risk of inconvenience in installing the sealing strip. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, the utility model proposes a magnetic door painting limit process lock.

[0006] To this end, the technical solution of the utility model is a magnetic door painting limit process lock, including a connecting block, characterized in that: a card joint is fixed to one side of one end face of the connecting block in the length direction, a card slot is provided on the opposite side of the card joint away from the connecting block, the card slot is adapted to the edge of the stopper of the vehicle body door opening, and a fastening hexagonal bolt vertically connected to the card slot is provided on the outer side of the card joint.

[0007] A threaded rod extending through the connecting block is provided at the other end of the connecting block, opposite to the card joint. The threaded rod is fixed to the connecting block by nuts provided on both sides. A magnetic head is fixed to the end of the threaded rod away from the connecting block.

[0008] A further improvement to the above technical solution is that a knob handle is fixed to the outer end of the tightening hexagonal bolt, which facilitates manual operation without the aid of other tools.

[0009] A further improvement to the above technical solution is that a plastic sheath is provided on the threaded rod to protect the thread from being contaminated by paint and affect normal use, and to facilitate adjustment of the position of the magnetic head according to different car models.

[0010] A further improvement to the above technical solution is that the fastening hexagonal bolt is connected to the clamping joint via a hexagonal nut, which is welded to the surface of the clamping joint. Existing materials are used for welding and fixing, and the hexagonal bolt and hexagonal nut are easily available.

[0011] Beneficial Effects: When using the present invention, the card slot of the card connector is connected to the edge of the door opening stop located below the vehicle body window, the hexagonal bolt is tightened, and the vehicle door is pushed to the inner wall to be attracted by the magnetic head, thereby limiting the position of the vehicle door. It is very convenient to use, and since it is located on the inside of the vehicle door, paint residue will not fall on the door surface. During the trial, no deformation of the vehicle body stop was found. When opening the vehicle door, only the process hole or the door gap on the vehicle door can be hooked with a wire to open the vehicle door, and the subsequent spraying of the inner side of the vehicle door can be carried out. The present invention has a simple structure, low manufacturing cost, is easy to use, saves labor and effort, and effectively improves the painting quality of the vehicle door, reduces costs, and improves efficiency.

[0015] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings, but this embodiment should not be understood as limiting the present invention.

[0016] The utility model Figure 1 and Figure 2 As shown:

[0017] A magnetic door paint limit lock includes a connecting block 1. A clamping joint 2 is fixed to one side of one end face of the connecting block in the longitudinal direction. The purpose of the design of the bias to one side is to avoid interference between the connecting block and the clamping joint when the clamping joint clamps the stopper of the vehicle body door opening. A clamping slot 3 is provided on the opposite side of the clamping joint away from the connecting block. The clamping slot is adapted to the edge of the stopper of the vehicle body door opening. A fastening hexagonal bolt 4 is provided on the outside of the clamping joint and is perpendicularly connected to the clamping slot.

[0018] A threaded rod 5 extending through the connecting block is provided at the other end of the connecting block 1, opposite to the card joint. The threaded rod is fixed to the connecting block by nuts 6 on both sides. A magnetic head 7 is fixed to the end of the threaded rod away from the connecting block by screws.

[0019] A knob handle 8 is fixed to the outer end of the tightening hexagonal bolt, which is convenient for manual operation without the aid of other tools; a plastic sheath 9 is provided on the outside of the threaded rod to protect the thread from being contaminated by paint and affecting normal use, and to facilitate adjustment of the position of the magnetic head according to different vehicle models; the tightening hexagonal bolt is connected to the card joint through the hexagonal nut 10, and the hexagonal nut is welded and fixed to the surface of the card joint. It is welded and fixed with existing materials. The hexagonal bolt and hexagonal nut are existing commodities that can be purchased and used immediately, and the cost is low.

[0020] The working principle of this utility model:

[0021] When in use, connect the card slot of the card connector to the edge of the door opening stop located below the door window (different from the installation position in the existing technology, it can be any position below the door window), tighten the fixing hexagonal bolt, push the door to the inner wall and abut against the magnetic suction head for adsorption, and the door can be limited under the action of magnetic force. It is very convenient to use, and it is located on the inside of the door and is not restricted by the installation position, and paint residue will not fall on the surface of the door. When opening, you only need to use a wire to hook the process hole or the door gap on the door to open the door. At this time, the door is disengaged from the process lock, and the subsequent spraying of the inside of the door can be carried out. When the process lock needs to be removed, you only need to loosen the fixing hexagonal bolt to remove it.

[0022] Parts not described in detail in this specification are well-known technologies in the art.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
