For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0044] See also Figure 1-4 The utility model provides a technical solution: a quick assembly jig for automobile wiring harnesses, comprising:

[0045] Binary fixture head 1;

[0046] A connecting rod 3, the upper end of which is welded to the middle of the bottom surface of the two-fork fixture head 1;

[0047] The lower end of the connecting rod 3 is equipped with a conveniently disassembled screw seat 4. The conveniently disassembled screw seat 4 is used to replace the screw portion at the lower end of the two-pronged fixture. The connecting rod 3 can be easily disassembled from the conveniently disassembled screw seat 4, and the installation is also convenient. The entire device is screwed to the base through the conveniently disassembled screw seat 4, making it easier to disassemble the components on the connecting rod 3.

[0048] The conveniently assembled wire harness clamping portion 2 is fixedly assembled on the upper end of the two-pronged fixture head 1. The wire harness can be quickly clamped into the two-pronged fixture head 1 and can also be easily disassembled.

[0049] In some embodiments, in order to facilitate the installation and removal of the automotive wiring harness, the wiring harness clamping portion 2 includes:

[0050] A first rectangular rod 21, which is longitudinally welded to one end of the upper side of the two-pronged fixture head 1;

[0051] A second rectangular rod 23, which is longitudinally welded to the other side of the upper side of the two-fork fixture head 1;

[0052] A fixed arc-shaped rod 22 is fixedly connected to the middle of the inner side surface of the first rectangular rod 21;

[0053] The upper end of the inner side surface of the second rectangular rod 23 is equipped with a hinged arc rod 24;

[0054] The articulated arc-shaped rods 24 and the fixed arc-shaped rods 22 are arranged alternately up and down.

[0055] When the wiring harness is installed, it enters from the gap between the articulated arc rod 24 and the fixed arc rod 22. The wiring harness squeezes the inner end of the articulated arc rod 24 and flips upward, forming a larger gap for the wiring harness to enter. After the wiring harness passes through the gap, the inner end of the articulated arc rod 24 flips back to its original position, shielding the top of the fixed arc rod 22 to reduce the probability of the wiring harness accidentally falling out after being clamped.

[0056] In some embodiments, in order to reduce the probability of accidental disengagement of the wiring harness after assembly, one end of the fixed arc rod 22 located inside the binary jig head 1 extends to below the articulated arc rod 24, and the distance between one end of the fixed arc rod 22 located inside the binary jig head 1 and the inner wall of the binary jig head 1 on the same side is greater than the outer diameter of the automotive wiring harness to be assembled. This discharge size is only slightly larger than the outer diameter of the automotive wiring harness, which can better prevent the wiring harness from accidentally disengaging after assembly.

[0057] In some embodiments, in order to make the welding transition between the upper end of the binary jig head 1 and the lower ends of the first rectangular rod 21 and the second rectangular rod 23 smoother, a round-to-square transition section 6 is welded between the upper end of the binary jig head 1 and the lower ends of the first rectangular rod 21 and the second rectangular rod 23.

[0058] In some embodiments, in order to avoid scratching the wire harness, the fixed arc rod 22 and the hinged arc rod 24 are integrally formed with an arc-shaped round cap 7 at the ends located inside the two-pronged fixture head 1, and the outer wall of the arc-shaped round cap 7 is an arc surface with a smooth surface.

[0059] In some embodiments, in order to enable the arc rod body 243 to flip upward when the wiring harness to be assembled is squeezed, so as to provide a larger clearance for the wiring harness to pass through, the arc rod body 243 is reset and shielded above the fixed arc rod 22 after the wiring harness passes through, and the articulated arc rod 24 includes:

[0060] A rectangular window 241 is provided at the upper ends of the left and right side walls of the second rectangular rod 23;

[0061] The upper ends of the front and rear side walls of the rectangular window 241 are rotatably connected to a rotating shaft 242 near the middle of the two-fork fixture head 1;

[0062] The upper end of the arc-shaped rod body 243 is fixedly sleeved on the rotating shaft 242, and the lower end of the arc-shaped rod body 243 extends into the two-fork fixture head 1;

[0063] A horizontal plate 244 is fixedly connected to the upper end of the outer side surface of the arc-shaped rod body 243;

[0064] A spring 245 is fixedly connected between the bottom surface of the horizontal plate 244 and the bottom surface of the inner cavity of the rectangular window 241. When the inner end of the arc rod body 243 flips upward, the horizontal plate 244 flips downward to squeeze the spring 245 to contract. After the external squeezing force is removed, the spring 245 drives the horizontal plate 244 and the arc rod body 243 to reset.

[0065] In some embodiments, in order to make the direction in which the spring 245 is compressed substantially the same as the flipping direction of the cross plate 244 and provide better elastic reset capability, the lower end of the spring 245 is inclined toward one side of the middle of the two-fork fixture head 1 .

[0066] In some embodiments, in order to facilitate the removal of the automobile wiring harness from the portable wiring harness clamping portion 2, one end of the fixed arc rod 22 located inside the two-pronged fixture head 1 is bent from horizontal to inclined upward.

[0067] In some embodiments, in order to enhance the welding strength between the connecting rod 3 and the binary fixture head 1 , a reinforcing welding material 5 is provided between the upper end of the connecting rod 3 and the middle of the bottom surface of the binary fixture head 1 .

[0068] In some embodiments, in order to facilitate the disassembly and installation of the connecting rod 3 and its upper part and the easily disassembled screw connection seat 4, the easily disassembled screw connection seat 4 is screwed and fixed on the base, and the easily disassembled screw connection seat 4 includes:

[0069] The sleeve 41 has a sealing design at its lower end;

[0070] The lower end of the connecting rod 3 is inserted into the sleeve 41;

[0071] A fixing bolt 42 is screwed to the upper end of the outer wall of the sleeve 41, and the end of the fixing bolt 42 abuts against the outer wall of the connecting rod 3. After the fixing bolt 42 is loosened, the connecting rod 3 can be removed from the sleeve 41, and the connecting rod 3 and its upper part can be fixed in the sleeve 41 by reverse operation;

[0072] The upper end of the screw rod 43 is coaxially fixedly connected to the sealing end of the lower end of the sleeve 41.

[0073] Working principle:

[0074] The connecting rod 3 has an upper end welded to the middle of the bottom surface of the two-pronged fixture head 1, and the lower end of the connecting rod 3 is equipped with a conveniently disassembled screw seat 4. The conveniently disassembled screw seat 4 is used to replace the screw portion of the lower end of the two-pronged fixture. The connecting rod 3 can be easily disassembled from the conveniently disassembled screw seat 4, and the installation is also convenient. The entire device is screwed to the base through the conveniently disassembled screw seat 4, making it easier to disassemble the components on the connecting rod 3;

[0075] The conveniently assembled wire harness clamping portion 2 is fixedly assembled on the upper end of the two-pronged fixture head 1. The wire harness can be quickly clamped into the two-pronged fixture head 1 and can also be easily disassembled.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
