Description

Technical Field

[0001] This utility model relates to the field of automotive armrest frame technology, specifically a heat straightening fixture for armrest frame production. Background Technology

[0002] A car armrest frame refers to the skeletal structure in a car seat armrest used to support and secure the armrest components. It is typically made of metal or sturdy plastic to ensure sufficient stability and load-bearing capacity. The main function of a car armrest frame is to provide support, allowing drivers and passengers to comfortably place their arms while seated, reducing arm fatigue during long drives or sitting.

[0003] In the current production process of automotive armrest frames, thermal straightening technology is required to restore the deformation of the frame caused by external forces. However, the existing clamps for gripping the armrest frame for heating lack a structure for continuous clamping during use, which requires the user to hold the clamp to hold the frame for heating. This causes hand fatigue and reduces the efficiency of restoration. Based on the shortcomings of the existing technology, this utility model designs a thermal straightening clamp for armrest frame production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a thermal straightening fixture for the production of handrail frames, which has the advantage of continuously clamping the handrail frames.

[0005] This utility model provides the following technical solution: a heat-correcting fixture for handrail frame production, comprising a fixing tube, an inner groove inside the fixing tube, a one-way structure installed on one side of the outer surface of the fixing tube, and a pulling structure slidably installed inside the inner groove; the one-way structure includes two first fixing plates, an inclined frame fixedly installed between the two first fixing plates, a locking strip fixedly installed inside the inclined frame, a triangular locking block slidably installed in the inner cavity of the inclined frame, the triangular locking block being slidably connected to the locking strip, three first springs fixedly installed on the top of the triangular locking block, one end of the top of the three first springs being fixedly connected to the top of the inner cavity of the inclined frame, and a lifting rod fixedly installed on the top of the triangular locking block, the lifting rod being movably connected to the inclined frame; the pulling structure includes a push rod, a toothed pressure strip fixedly installed on one side of the outer surface of the push rod, a handle fixedly installed on one end of the push rod, a second spring fixedly installed on one side of the bottom of the handle, and one end of the second spring being fixedly connected to the fixing tube.

[0006] As a preferred embodiment of this utility model, a first hinge seat is fixedly installed on both sides of the outer surface of the fixed tube, and hinge grooves are provided on both sides of the bottom of the push rod.

[0007] As a preferred embodiment of this utility model, a clamping structure is internally hinged to the two first hinge seats, and the clamping structure includes two first hinge rods.

[0008] As a preferred embodiment of this utility model, the two first hinge rods are hingedly connected to the first hinge seat, and two second fixing plates are fixedly installed at one end of the two first hinge rods.

[0009] As a preferred embodiment of this utility model, a clamping plate is fixedly installed at one end of each of the two second fixing plates, and a pad is provided inside the two clamping plates.

[0010] As a preferred embodiment of this utility model, a second hinge seat is fixedly installed on one side of each of the two first hinge rods, and a second hinge rod is hingedly installed on one end of each of the two second hinge seats.

[0011] As a preferred embodiment of this utility model, the two second hinge rods are hinged to the hinge groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This heat-correcting clamp for handrail frame production, through a one-way, pulling structure, allows the clamping structure to hold the frame when the pulling structure is pulled. Pulling the handle stretches the second spring, causing the push rod to move within the inner groove. Simultaneously, because one of the inclined sides of the triangular locking block engages with the gap in the toothed pressure bar, the triangular locking block slides upwards within the pressure bar as the push rod moves the pressure bar. Due to the first spring, when the triangular locking block reaches its highest point, it falls into the second gap in the toothed pressure bar. When the push rod is stopped and the frame is clamped, the triangular locking block again engages in the gap in the toothed pressure bar, preventing the push rod from retracting due to the second spring's rebound. This continuously clamps the handrail frame. When it is necessary to release the clamp, pulling the lever upwards causes the triangular locking block to disengage from the toothed pressure bar. The second spring then rebounds, causing the push rod to reset and release the handrail frame. This achieves the purpose of continuously clamping the handrail frame.

[0014] 2. The heat straightening fixture for the production of handrail frames, through a pulling structure and a clamping structure, when the push rod is pulled, due to the hinge of the second hinge rod and the hinge groove, the included angle of the two second hinge rods becomes smaller, thereby driving the second fixing plates on both sides to fold inward at the same time. The car handrail frame can be clamped through the second hinge seat, thereby completing the subsequent heat straightening work. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A heat-correcting fixture for handrail frame production includes a fixing tube 1, with an inner groove 101 inside the fixing tube 1. A one-way structure 2 is installed on one side of the outer surface of the fixing tube 1, and a pulling structure 3 is slidably installed inside the inner groove 101. The one-way structure 2 includes two first fixing plates 21, with a diagonal frame 22 fixedly installed between the two first fixing plates 21. A retaining strip 23 is fixedly installed inside the diagonal frame 22, and a triangular retaining block 24 is slidably installed inside the diagonal frame 22. The triangular retaining block 24 is slidably connected to the retaining strip 23. Three first springs 25 are fixedly installed on the top of block 24. One end of the top of the three first springs 25 is fixedly connected to the top of the inner cavity of the inclined frame 22. A lifting rod 26 is fixedly installed on the top of the triangular block 24. The lifting rod 26 is movably connected to the inclined frame 22. The pulling structure 3 includes a push rod 31. A toothed pressure strip 33 is fixedly installed on one side of the outer surface of the push rod 31. A handle 35 is fixedly installed on one end of the push rod 31. A second spring 34 is fixedly installed on one side of the bottom of the handle 35. One end of the second spring 34 is fixedly connected to the fixed tube 1.

[0023] Please see Figure 1-2The first hinge seat 102 is fixedly installed on both sides of the outer surface of the fixed tube 1, and the bottom sides of the push rod 31 are provided with hinge grooves 32.

[0024] Side grooves are provided on both sides of the inner groove 101 to prevent the push rod 31 from rotating inside the inner groove 101.

[0025] Please see Figure 1 and Figure 5 Two first hinge seats 102 are internally hinged to clamping structures 4, each clamping structure 4 including two first hinge rods 41. The two first hinge rods 41 are hingedly connected to the first hinge seats 102, and two second fixing plates 42 are fixedly mounted at one end of each first hinge rod 41. Clamping plates 43 are fixedly mounted at one end of each second fixing plate 42, and pads are provided inside the clamping plates 43. Second hinge seats 44 are fixedly mounted on one side of each first hinge rod 41, and second hinge rods 45 are hingedly mounted at one end of each second hinge seat 44. The two second hinge rods 45 are hingedly connected to hinge slots 32.

[0026] When the push rod 31 is pulled, the angle between the two second hinge rods 45 and the hinge groove 32 becomes smaller due to the hinge. This causes the two second fixing plates 42 on both sides to fold inward at the same time. The car armrest frame can be clamped by the second hinge seat 44, thereby completing the subsequent heat correction work.

[0027] Working principle: When a heat straightening fixture for armrest frame production is used, firstly, the handle 35 is pulled, causing the second spring 34 to stretch, which in turn moves the push rod 31 inside the inner groove 101. Due to the hinge between the second hinge rod 45 and the hinge groove 32, the included angle between the two second hinge rods 45 becomes smaller, thereby causing the two second fixing plates 42 on both sides to fold inward simultaneously. The second hinge seat 44 can clamp the car armrest frame, thus completing the subsequent heat straightening work. At the same time, since one of the inclined sides of the triangular block 24 is in contact with the gap of the toothed pressure bar 33, when the push rod 31 moves the toothed pressure bar 33, it can drive the three... The triangular locking block 24 slides upward inside the locking strip 23. Due to the setting of the first spring 25, when the triangular locking block 24 moves to the highest point, it falls into the second gap in the toothed pressure strip 33. Until the push rod 31 stops pulling and clamps the frame, the triangular locking block 24 is locked in the gap of the toothed pressure strip 33 again, preventing the push rod 31 from retracting due to the rebound of the second spring 34. Thus, the armrest frame can be continuously clamped. When it is necessary to release the clamp, the lifting rod 26 is held up and pulled upward. The triangular locking block 24 can then fall out of contact with the toothed pressure strip 33. At this time, the second spring 34 rebounds and the push rod 31 resets, releasing the frame armrest.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
