[0029] This utility model proposes a door support fixture 100.
[0030] Please see Figure 1 and Figure 2 In one embodiment of this utility model, an installation hole is provided on the inner side of the car door, and an inner cavity communicating with the installation hole is formed inside the car door; the support fixture 100 includes a support column 1, a limiting plate 2, and a locking assembly 3. The two ends of the support column 1 along its axial direction are a support end 11 and a connecting end 12, respectively. The support end 11 is used to abut against the door frame; the opposite sides of the limiting plate 2 are a first connecting side 21 and a second connecting side 22, respectively. The first connecting side 21 is connected to the connecting end 12. A through hole 23 is provided on the limiting plate 2. The through hole 23 extends from a position near the support column 1 in a direction away from the support column 1, and the side wall of the through hole 23 away from the support column 1 forms a limiting wall 231; the locking assembly 3 includes The lock block 31 and the lock rod 32 are connected to the second connecting side 22. The lock rod 32 passes through the through hole 23 and is hinged to one side of the lock block 31 so that the lock rod 32 can rotate relative to the lock block 31 between the locked position and the unlocked position, and the side of the lock rod 32 away from the lock block 31 abuts against or disengages from the limiting wall 231. The side of the lock rod 32 away from the lock block 31 also forms a limiting step 324. When the lock rod 32 is in the unlocked position, the lock block 31 can pass through the mounting hole and extend into the inner cavity, and the limiting plate 2 abuts against the inner side of the door. When the lock rod 32 is in the locked position, the limiting step 324 can form a first lock groove 325 between itself and the second connecting side 22 for engaging with the hole wall of the mounting hole.
[0031] The door support fixture 100 of this utility model adopts a support column 1, a limiting plate 2, and a locking assembly 3. The support end 11 of the support column 1 supports the door frame, the first connecting side 21 of the limiting plate 2 is connected to the connecting end 12, and the locking assembly 3 is connected to the second connecting side 22 of the limiting plate 2. During installation, the locking rod 32 is rotated around the locking block 31 and placed in the unlocked position. At this time, the locking rod 32 is disengaged from the abutment wall, making it easy to insert the locking block 31 of the locking assembly 3 through the mounting hole into the inner cavity. Then, the locking rod 32 is rotated to the locked position, at which time the locking rod 32 abuts against the abutment wall, and the limiting position of the locking rod 32 is achieved. A first locking groove 325 is formed between the step 324 and the second connecting side 22. The first locking groove 325 engages with the wall of the mounting hole to install the entire door support fixture 100 at the mounting hole. In addition, due to the setting of the limiting plate 2, when the limiting plate 2 abuts against the inner side of the door during installation, it indicates that the locking block 31 has been inserted into place. At this time, it can be locked by the locking rod 32. Since the abutting end of the support column 1 abuts against the door, a certain distance is maintained between the door and the door frame when you open and close the door, preventing the door and the frame from colliding and ensuring the spraying quality and the integrity of the coating. During disassembly, by moving the locking rod 32 to rotate around the locking block 31 and put it in the unlocked position, the locking rod 32 disengages from the abutting wall. At this time, the locking rod 32 can be pulled out from the mounting hole to remove the entire door support fixture 100 from the door. As can be seen, the door support fixture 100 can be quickly installed on and removed from the door by moving the locking lever 32. It is easy to install and remove, and its simple structure makes it easy to clean.
[0032] In one embodiment, the two ends of the locking rod 32 are a free end 3231 and a hinged end 3211, respectively. The hinged end 3211 is hinged to the locking block 31, and the free end 3231 extends through the through hole 23 to the support column 1. The free end 3231 can rotate around the hinged end 3211 so that the locking rod 32 can rotate relative to the locking block 31 between the locked position and the unlocked position. The side of the locking block 31 facing the locking rod 32 is the mounting side. A receiving groove 311 with a slot facing the locking rod 32 is opened on the mounting side away from the limiting plate 2. The hinged end 3211 is hinged to the receiving groove 311 through a rotating shaft.
[0033] The locking rod 32 has a free end 3231 and a hinged end 3211 at its two ends. A receiving groove 311 is provided on the mounting side of the locking block 31. The hinged end 3211 extends into the mounting groove and is hinged to the receiving groove 311 by a pivot, which effectively limits the positional displacement of the hinged end 3211 and reduces the overall volume of the support fixture 100. The free end 3231 extends through the through hole 23 to the support column 1, and the free end 3231 can rotate around the hinged end 3211, which is convenient for the operator to operate.
[0034] In one embodiment, the locking bar 32 includes a limiting section 321, an abutting section 322, and an operating section 323 connected in sequence. A limiting step 324 is formed at the connection between the limiting section 321 and the abutting section 322. The end of the limiting section 321 away from the abutting section 322 is a hinged end 3211, and the end of the operating section 323 away from the abutting section 322 is a free end 3231. The abutting section 322 passes through the through hole 23, and at least part of the limiting section 321 can be accommodated in the receiving groove 311 when the locking bar 32 is in the unlocked position.
[0035] Understandably, when in the unlocked position, the limiting section 321 of the locking rod 32 is at least partially accommodated in the receiving groove 311 of the locking block 31, so that the locking rod 32 is retracted into the locking block 31 as a whole, so that the locking block 31 can be inserted into or extended out of the mounting hole. In use, the user only needs to manually turn the operating end to realize the rotation of the locking rod 32, which is convenient to operate and makes installation and disassembly more convenient.
[0036] In one embodiment, an elastic member 33 is further provided between the limiting segment 321 and the locking block 31. One end of the elastic member 33 is connected to the bottom wall of the receiving groove 311, which is opposite to the groove opening, and the other end of the elastic member 33 abuts against the limiting segment 321.
[0037] Understandably, by providing an elastic element 33 between the limiting section 321 and the locking block 31, when the operating section 323 is pressed toward the support column 1 during use, the free end 3231 rotates around the hinge end 3211 to drive the limiting section 321 to compress the elastic element 33. When the operating section 323 is released, the free end 3231 rotates away from the support column 1 under the elastic restoring force of the elastic element 33, so that the abutting section 322 of the locking rod 32 abuts against the abutting wall of the through hole 23, thereby achieving automatic locking. The spring provides a continuous elastic force to ensure that the locking rod 32 always keeps the locking rod 32 in close contact with the limiting arm when there is no external force, thus improving the connection stability of the support fixture 100.
[0038] In one embodiment, the elastic element 33 is a spring, and the locking rod 32 is provided with a mounting protrusion 3212 corresponding to the position of the spring, with the spring sleeved on the mounting protrusion 3212. By providing the mounting protrusion 3212, the spring can be accurately sleeved on the mounting protrusion 3212, preventing the spring from shifting, tilting, or falling out during compression or rebound.
[0039] Understandably, when the locking rod 32 is in the locked position, there is a clearance between the mounting protrusion 3212 and the bottom wall of the receiving groove 311 that is opposite to the groove opening.
[0040] In one embodiment, the abutting section 322 has an abutting area and a locking area on the side facing the limiting wall 231. The abutting area can abut against the limiting wall 231 and the abutting area and the limiting wall 231 are matched and configured to match each other. The locking area can form a first locking groove 325 with the limiting step 324 and the second connecting side 22 when the locking rod 32 is in the locked position.
[0041] The abutment area and the limiting wall 231 are matched so that their shapes match each other, ensuring that the abutment area and the limiting arm can fit together completely, increasing the contact area between the two, reducing local stress concentration, and preventing damage to the abutment wall and the locking rod 32. The through hole 23 can also position the locking rod 32 when it is locked, preventing the locking rod 32 from shaking.
[0042] Furthermore, the end connecting the operating section 323 and the abutment section 322 is a docking end 3232, and the docking end 3232 to the free end 3231 is inclined away from the support column 1. The outward inclination of the operating section 323, which moves its free end 3231 away from the support column 1, provides a clearance for the locking rod 32 to move, significantly improving the convenience of operation.
[0043] Furthermore, a clearance groove 13 extending axially is provided on the side of the support column 1 facing the operating section 323. The through hole 23 is located on the same side as the clearance groove 13 and the clearance groove 13 communicates with the through hole 23. By providing the clearance groove 13 to avoid the locking rod 32, the rotation range of the locking rod 32 is increased, so that it can accommodate more sizes of mounting holes, making the support fixture 100 more versatile.
[0044] Furthermore, a limiting notch 312 is provided on the side of the lock block 31 away from the lock rod 32. The limiting notch 312 and the second connecting side 22 form a second locking groove for engaging with the wall of the mounting hole.
[0045] By forming a second locking groove, when the locking rod 32 is in the unlocked position, the locking block 31 can pass through the mounting hole. At this time, the second locking groove can first engage with the wall of the mounting hole to achieve temporary fixation. Then, under the action of elastic restoring force, the locking rod 32 engages with the wall of the mounting hole, further increasing the locking stability. Moreover, the first locking groove 325 and the second locking groove are arranged opposite to each other, and their cooperation makes the locking effect better, improving the stability of the support fixture 100 installed in the mounting hole.
[0046] In one embodiment, the support end 11 is equipped with an elastic pad 111 for abutting against the door frame. By providing the elastic pad 111, the elastic pad 111 has good cushioning ability and can prevent scratches or bumps to the door frame or damage to the painted surface when in contact with the door frame.
[0047] Furthermore, the support column 1 is hollow to reduce the weight of the entire support fixture 100 and achieve the purpose of lightweighting.
[0048] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
