Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a side-opening hatch door adsorption and fixing device, application and working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The side hatch of a car has the characteristics of easy door opening and operation. In addition, since stamping parts have the advantages of high precision, mass production and low cost, most manufacturers usually use iron stamping parts to assemble the side hatch. During the assembly process, the side hatch needs to be fixed. In the prior art, iron wire bundling or round steel hooks are usually used for fixing: painting involves multiple processes such as spraying, foaming, pattern pasting and paint spraying. The frequent bundling and disassembly of iron wire are many, the construction is inconvenient, and the bundling part has interference with the spraying, which affects the construction efficiency; another method is to use round steel to make a hook, and the hook is fixed to the side hatch through the lock hole part and the hole part of the bottom plate in the warehouse, but there are also problems: because the fixed position of the bottom plate hole in the warehouse is inconsistent due to the production order configuration, it is necessary to make a variety of round steel fixing hooks of different specifications according to the production order, which is not universal and inconvenient to install the hook.

[0004] In addition, during the coating production, construction, baking and transportation process of the side hatch door, the side hatch door is very easy to open naturally due to loose fixation, causing the side hatch door to collide and deform. After the side hatch door is collided and deformed, it needs to be repaired, and repair paint problems will occur, which will affect the paint delivery progress and increase the workload and cost of repair paint. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a side-opening hatch door adsorption and fixing device, which effectively improves production efficiency, is easy to disassemble, and has a wide range of applications.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0007] A side-opening hatch door adsorption and fixing device comprises a support rod, a connecting tube is circumferentially sleeved on the support rod, the support rod is rotatable relative to the connecting tube, the length of the support rod is longer than the connecting tube, a magnetic part is fixedly arranged on the outside of the connecting tube, the magnetic part protrudes from the connecting tube, both ends of the support rod are bent, one end of the support rod can drive the connecting tube to extend into the lock hole of the side-opening hatch door, the size of the magnetic part is larger than the inner diameter of the lock hole of the side-opening hatch door, the part of the magnetic part protruding from the connecting tube can be adsorbed and fixed to the hatch door panel, and one end of the support rod located on the inner side of the side-opening hatch door contacts the lock seat and provides a force to prevent the side-opening hatch door from sliding freely.

[0008] In the above-mentioned adsorption and fixing device for a side-opening hatch, the connecting pipe is circumferentially provided with limit members on both sides of the magnetic member, the limit members are fixedly connected to the connecting pipe to limit the magnetic member, the outer diameter of the limit member is matched with the inner diameter of the lock hole of the side-opening hatch door so that the limit member can enter the lock hole of the side-opening hatch door, and the magnetic member is a magnet ring, and the outer diameter of the magnetic member is larger than the outer diameter of the limit member.

[0009] According to the above-mentioned side-opening hatch door adsorption and fixing device, the support rod includes a screw rod, both ends of the screw rod are respectively arranged beyond the connection pipe, and fixing rods are respectively arranged at both ends of the screw rod, and the fixing rods are bent;

[0010] The length of the screw rod is greater than the depth of the lock hole of the side-opening door, so that space is reserved between the fixing rods at both ends and the side-opening door.

[0011] As described above, in an adsorption and fixing device for a side-opening hatch door, the fixing rod comprises a first fixing rod arranged at one end of the screw rod and a second fixing rod arranged at the other end of the screw rod, the first fixing rod is bent in a first plane, the second fixing rod is bent in a second plane, and the first plane and the second plane are perpendicular to each other, so that when the first fixing rod or the second fixing rod contacts the lock seat on the side and is parallel to the upper side surface of the door frame, the second fixing rod or the first fixing rod is in a vertical state, which is convenient for judging the state of the side-opening hatch door.

[0012] In the above-mentioned adsorption and fixing device for a side-opening hatch, when the first fixing rod is in a horizontal state, the side of the second fixing rod away from the screw rod is in a vertical downward state relative to the first fixing rod.

[0013] In the above-mentioned side-opening door adsorption and fixing device, nuts are fixedly connected to the two ends of the connecting pipe respectively, the screw rod is rotatable relative to the nut, and the nut and the connecting pipe are connected as a whole. If the first fixing rod is in contact with the lock seat and the second fixing rod is not in a vertical state, the second fixing rod can be automatically rotated relative to the nut under force until the second fixing rod is in a vertical downward state.

[0014] As described above, in a side-opening hatch door adsorption and fixing device, a protective tube is fixedly arranged on the outer side of the nut to protect the screw rod, and the screw rod is arranged beyond the protective tube. The screw rod is rotatable relative to the protective tube. The protective tube plays a role in protecting the screw rod to prevent the screw rod at the outer end of the connecting tube from being affected by the false paint sprayed on it and affecting its rotation.

[0015] In the above-mentioned adsorption and fixing device for a side-opening hatch, the nut is spot-welded to the connecting pipe, and the protective pipe is spot-welded to the nut.

[0016] In a second aspect, the present invention further discloses an application of a side-opening hatch adsorption and fixing device, which is applied to the painting, drying and transportation processes of the side-opening hatch of an automobile.

[0017] In a third aspect, the present invention further discloses a working method of a side-opening hatch door adsorption and fixing device, including the following contents:

[0018] Pass one end of the support rod through the lock hole of the side door and come to the other side of the door panel. The connecting pipe can enter the lock hole of the side door. The magnetic part is attached to the outer side or inner side of the door panel. The end of the support rod located on the inner side of the door panel contacts the lock seat and provides a force to the lock seat, so that the side door remains closed.

[0019] The support rod is rotated relative to the connecting pipe so that one end of the support rod is separated from the lock seat. At this time, the side-opening hatch is in a naturally open state.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1) In the present invention, the support rod is circumferentially sleeved with a connecting tube, and a magnetic member is arranged on the outside of the connecting tube, and the size of the magnetic member is larger than the inner diameter of the lock hole of the side hatch door, so that when the support rod passes through the lock hole of the side hatch door, the magnetic member is exposed at the lock hole of the side hatch door, and the magnetic member can be adsorbed and fixed to the iron side hatch door, and the end of the support rod located on the inner side of the side hatch door can provide a force to the lock seat. Because the lock seat is arranged on the door frame, this is equivalent to arranging a component in the lock hole of the side hatch door to press the lock seat, so that the side hatch door is locked relative to the lock seat and is not in a naturally open state. The overall structure is simple, and there is no need to tie the side hatch door or make a hook to hang the side hatch door for construction, which greatly facilitates the painting construction, improves the construction efficiency, and is conducive to shortening the delivery schedule.

[0022] 2) The entire device of the present invention utilizes the space of the lock hole of the side hatch door, and space is also reserved between the two sides of the support rod and the side hatch door. No interference will occur during the spraying process of the side hatch door, and the setting position of the magnetic part can be determined according to the inner or outer side of the hatch door panel to be constructed, thereby effectively avoiding the construction surface to be constructed; because the magnetic part and the side hatch door can be firmly adsorbed and fixed, the side hatch door is prevented from opening naturally during the spraying process of the side hatch door, which effectively avoids the problem of collision and deformation of the side hatch door, and effectively reduces the workload and cost of repainting.

[0023] 3) In the present invention, the support rod includes a screw rod, and nuts are respectively arranged at both ends of the connecting pipe. The screw rod can rotate relative to the nut. In this way, when the magnetic part is adsorbed on the cabin door panel, the support rod can rotate relative to the connecting pipe, that is, relative to the magnetic part, so as to achieve contact or separation between one end of the support rod and the lock seat, thereby achieving adjustment of the opening or closing state of the opposite side cabin door.

[0024] 4) In the present invention, a first fixing rod and a second fixing rod are respectively arranged at the other end of the screw rod, and the first fixing rod and the second fixing rod are respectively bent relative to the screw rod, and the plane where the first fixing rod is located is perpendicular to the plane where the second fixing rod is located, and when the first fixing rod is in a horizontal state, the side of the second fixing rod away from the screw rod can be in a vertical downward state relative to the first fixing rod, so that the second fixing rod can be automatically rotated freely relative to the connecting pipe under force, thereby ensuring the contact force between the first fixing rod or the second fixing rod and the lock seat, and also facilitating the acquisition of the state of opening the hatch door on the opposite side.

[0035] As introduced in the background technology, in the prior art, the fixing method of the side-opening hatch in the production process has the problems of low construction efficiency and poor versatility. In order to solve the above technical problems, the present invention proposes an adsorption and fixing device for the side-opening hatch.

[0036] Embodiment 1

[0037] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a side-opening hatch door adsorption and fixing device comprises a support rod, a connecting pipe 1 is circumferentially sleeved on the support rod, the support rod is rotatable relative to the connecting pipe 1, the length of the support rod is longer than the connecting pipe 1, a magnetic member 4 is circumferentially sleeved on the connecting pipe 1, the thickness of the magnetic member 4 is less than the length of the connecting pipe 1, and both ends of the magnetic member 4 are respectively provided with limit members, the limit members are sleeved on the circumferential direction of the connecting pipe 1 and fixed to the connecting pipe 1, and the outer diameter of the limit member is adapted to the size of the lock hole of the side-opening hatch door, and is usually smaller than the inner diameter of the lock hole of the side-opening hatch door so that the limit member The part can enter the lock hole of the side-opening door 14 along with the connecting pipe. The inner diameter of the limit part is adapted to the outer diameter of the connecting pipe 1. The outer diameter of the limit part is larger than the inner diameter of the magnetic part 4 to limit the magnetic part. The limit part and the connecting pipe 1 are fixed to fix the magnetic part 4. The outer diameter of the magnetic part 4 is larger than the outer diameter of the limit part. In this way, after the limit part is extended into the lock hole of the side-opening door, the part of the magnetic part 4 exposed from the limit part is adsorbed and fixed to the door panel 14, thereby realizing the adsorption and fixation of the device and the side-opening door.

[0038] It is easy to understand that the limiting members on both sides of the magnetic member are respectively a first limiting member 2 and a second limiting member 3 , and the structures and sizes of the first limiting member 2 and the second limiting member 3 are the same.

[0039] Specifically, the connecting pipe 1 is a round tube, and the magnetic part 4 is a magnet ring (strong magnet ring). The outer diameter of the magnet ring is slightly larger than the inner diameter of the lock hole of the side-opening cabin door, so that the magnet ring can be placed on the side of the lock hole of the side-opening cabin door to be sucked and fixed with the cabin door panel; the magnetic part 4 can be sucked from the inside or outside of the cabin door panel 14, so that when constructing the outer side, the magnetic part 4 is sucked with the inner side of the cabin door panel 14, and when constructing the inner side, the magnetic part is sucked with the inner side of the cabin door panel, and no touch-up work is required.

[0040] The stopper and the connecting pipe 1 are fixed to each other by spot welding.

[0041] In this embodiment, the support rod includes a screw rod 5, which is circumferentially provided with an external thread. The screw rod 5 is longer than the length of the connecting tube 1. The inner diameter of the connecting tube 1 is larger than the outer diameter of the screw rod. The screw rod 5 is circumferentially provided with nuts at both ends of the connecting tube, which are a first nut 6 and a second nut 7 respectively. Each nut is fixedly connected to the end of the connecting tube, and can be fixed by spot welding, so that the nut and the connecting tube are an integrated structure, and the screw rod 5 can rotate relative to the nut.

[0042] It is easy to understand that protective tubes are respectively arranged on the outside of the first nut 6 and the second nut 7 of the screw rod 5. The two ends of the screw rod 5 extend out from the protective tubes on both sides. The first protective tube 10 is on the outside of the first nut, and the second protective tube 11 is on the outside of the second nut 7. The first protective tube 10 is spot-welded to the outer end face of the first nut, and the second protective tube 11 is spot-welded to the outer end face of the second nut. The two ends of the screw rod 5 are arranged beyond the first protective tube 10 and the second protective tube 11. Each protective tube is a protective circular tube. The inner diameter of the protective tube is larger than the outer diameter of the screw rod, which will not affect the rotation of the screw rod. The protective tube plays the role of protecting the screw rod to prevent the screw rod at the outer end of the connecting tube from being affected in its rotation due to false paint sprayed.

[0043] It is easy to understand that reference Figure 2 and Figure 3As shown, fixing rods are welded to the ends of the screw rod 5 that extend beyond the corresponding protective tubes, which are respectively a first fixing rod 8 that extends beyond the first protective tube 10 and a second fixing rod 9 that extends beyond the second protective tube 11. The first fixing rod 8 and the second fixing rod 9 are both bent, the first fixing rod 8 is bent in a first plane, and the second fixing rod 9 is bent in a second plane, the first plane and the second plane are perpendicular to each other, the first fixing rod 8 and the second fixing rod 9 are used for rotation adjustment of the outer side of the lock hole of the side-opening door, which is equivalent to the function of a handle, when the first fixing rod or the second fixing rod extends from the outer side of the side-opening door into the inner side of the side-opening door, the first fixing rod or the second fixing rod is used to contact the lock seat 13, the lock seat 13 is fixed to the door frame (skeleton steel 12), and is located on the side of the lock hole of the side-opening door, the bent first fixing rod or the second fixing rod can provide a force to the lock seat 13, which is equivalent to providing a device at the lock hole of the side-opening door, the device is not only fixed by suction with the door panel, but also can contact with the lock seat 13 and maintain a certain force, so that the side-opening door is in a closed state.

[0044] Specifically, the first fixing rod is bent into an L-shape, and the second fixing rod is also bent into an L-shape. When the first fixing rod is in a horizontal state, the side of the second fixing rod away from the screw rod is in a vertical downward state.

[0045] When using, refer to Figure 4 and Figure 5 As shown, on the inner side of the door panel 14, the first fixing rod 8 is fixed in horizontal contact with the door lock seat 13, and the second fixing rod 9 on the outer side of the door panel 14 is bent in a drooping state to better fix the side-opening door. Because the second fixing rod on the outside of the side-opening door is naturally rotated to a drooping state due to the force, the first fixing rod 8 on the inner side of the door panel is rotated under the force, thereby preventing the side-opening door from becoming a naturally open state, and the second fixing rod 9 on the outer side of the door panel is in a drooping state, indicating that the side-opening door is in a closed state, which is convenient for identifying the closed state of the side-opening door.

[0046] The device provided in this embodiment can be applied to the construction of automobile painting from front-end glue spraying to pattern pasting process: the first fixing rod is extended from the inner side of the hatch door panel 14 along the lock hole of the side-opening hatch door, the magnetic member 4 is adsorbed and fixed to the inner side of the side-opening hatch door panel 14, the second fixing rod is in contact with the lock seat 13, and the side-opening hatch door is opened and closed by rotating and adjusting the first fixing rod on the outer side of the hatch door panel, so as to avoid the problem that the magnetic member is adsorbed and fixed on the outer side of the hatch door panel to cover the part, resulting in the problem of poor painting and interference with the painting construction;

[0047] Alternatively, the device provided in this embodiment is applied to the construction of spraying lining paint on the inner side of the hatch door panel in the process of spraying lining paint on the inner side of the hatch door panel in the automobile lining paint process: the first fixing rod is extended from the outer side of the hatch door panel into the hatch door lock hole, the magnetic part 4 is adsorbed and fixed to the outer side of the hatch door panel, the first fixing rod contacts the lock seat 13 from the inner side of the hatch door panel, and the second fixing rod on the outer side of the hatch door panel is rotated and adjusted by a screw rod, so as to better realize the opening and closing of the side-opening hatch door, and solve the problems of loose painting and repair paint in the part covered by the magnetic part on the inner side of the side-opening hatch door.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
