Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness heating equipment, and in particular relates to a heating box for a wire harness. Background Art

[0002] Some wire harnesses need to be preheated during the processing to ensure the normal progress of subsequent processing links. The conventional heating method is to place the wire bobbin directly in the wire harness heating box for preheating. The wire harness heating box has an air electric heater, which can preheat the wire bobbin placed in the box and the wire harness on the wire bobbin by hot air. As disclosed in the existing patent with publication number CN221040642U, "a wire harness preheating box includes a box body, a through slot is opened at the front of the box body, a left box door and a right box door are rotatably installed in the through slot, a plurality of support plates are fixedly installed in the box body, and an air electric heater is fixedly installed on the bottom surface of the inner wall of the box body", it can be seen that the application describes a common heating box for wire harnesses;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] See also Figures 1 to 5 , is an embodiment of the utility model, which provides a technical solution: a heating box for a wiring harness, comprising

[0026] A heating box body 1, a box door 2 arranged on the front surface of the heating box body 1, a wire outlet 3 opened on the top surface of the heating box body 1, an air electric heater 6 installed at the bottom end of the inner side of the heating box body 1, an inner support plate 11 fixed on the inner side of the heating box body 1 and above the air electric heater 6, a top plate 12 installed on the top surface of the inner support plate 11, a base column 14 fixed on the top of the top plate 12, and a wire barrel 7 sleeved on the surface of the base column 14. The model of the air electric heater 6 is ZRYD-360, which is a common air duct heating element. After operation Hot air can be blown out, and multiple vents with filters 13 are provided on both sides of the inner support plate 11, so that when the air electric heater 6 is running, hot air flows to the top of the inner support plate 11, thereby preheating the wire harness on the wire drum 7, and then the wire harness wound on the wire drum 7 passes through the support ring 42 and is pulled out of the wire outlet 3 to perform subsequent processing of the wire harness, and the above-mentioned partial structural principles are all existing technologies that have been disclosed in existing patents. For details, please refer to the existing patent with publication number CN221040642U, which will not be described in detail here;

[0027] and a support column 4 installed through the top surface of the heating box body 1, a support ring 42 installed at the bottom end of the support column 4 and located inside the heating box body 1, and a top block 41 welded and fixed to the top end of the support column 4 and located at the top of the heating box body 1, and a through hole 15 for the support column 4 to pass through the top surface of the heating box body 1 is opened;

[0028] And an adjustment mechanism arranged between the heating box body 1 and the support column 4, including a side groove 53 opened on the side wall of the through hole 15, a spring 54 and a side slider 55 installed in the side groove 53, a side clamping rod 56 welded and fixed to the side of the side slider 55, a plurality of limit clamping holes 52 opened on the surface of the support column 4, a connecting block 57 welded and fixed on the top surface of the side slider 55, and a top slide 58 opened on the top surface of the heating box body 1 for the connecting block 57 to slide, and the top end of the connecting block 57 passes through the top slide 58 to the top of the heating box body 1 and is fixed with an L-shaped block 51. When actually used, the side slider 55 will be pushed by the spring 54, so that the side clamping rod 56 is inserted into one of the limit clamping holes 52, thereby engaging and limiting the support column 4 to ensure that the support column 4 is locked. To ensure the height stability of the support column 4 and the supporting ring 42, when the height of the supporting ring 42 needs to be adjusted laterally, it is only necessary to pull the L-shaped block 51 sideways, so that the connecting block 57 moves sideways with the side slider 55 and compresses the spring 54, so that the end of the side clamping rod 56 moves out of the limiting clamping hole 52, and the limiting of the support column 4 can be released. At this time, the support column 4 can be slid up and down for height adjustment, thereby changing the height of the supporting ring 42. When it is adjusted to a suitable height, the L-shaped block 51 is released, so that the spring 54 pushes the side slider 55 back to reset, and the side clamping rod 56 can be inserted into the limiting clamping hole 52 at other positions, so that the support column 4 can be limited again, completing the support and limiting of the support column 4 and the supporting ring 42, and completing the rapid adjustment of the height of the supporting ring 42.

[0029] A cylindrical groove is formed on the inner wall of the side groove 53 , one end of the spring 54 is embedded in the cylindrical groove, and the other end of the spring 54 is fixedly connected to the side slider 55 .

[0030] The side slider 55 is slidably located in the side groove 53 , and the side slider 55 is rectangular.

[0031] Among them, a bottom block 43 is fixed to the bottom end of the support column 4, a rotating seat 44 is welded and fixed to the left surface of the supporting ring 42, and the rotating seat 44 is rotatably installed at the bottom of the bottom block 43, so that the supporting ring 42 can be rotated and adjusted later, further improving the flexibility of use. A shaft rod with a T-shaped cross-section is fixed to the bottom surface of the bottom block 43, and the rotating seat 44 is rotatably sleeved on the shaft rod, so that the rotating seat 44 can smoothly rotate at the bottom of the bottom block 43, thereby realizing the rotation adjustment of the supporting ring 42.

[0032] Among them, a rubber side piece 45 is glued and fixed to the side of the rotating seat 44, and the top end of the rubber side piece 45 extends to one side of the bottom block 43. A hemispherical protrusion 46 is arranged on the top side of the rubber side piece 45, and a plurality of positioning grooves 47 corresponding to the hemispherical protrusion 46 are opened on the circumferential surface of the bottom block 43. The end of the hemispherical protrusion 46 is embedded in one of the positioning grooves 47, which can play a certain limiting role on the rotating seat 44 and the supporting ring 42. When the rotating seat 44 and the supporting ring 42 rotate subsequently, the end of the hemispherical protrusion 46 will be squeezed into the positioning grooves 47 at other positions, thereby realizing auxiliary positioning of the rotating seat 44 and the supporting ring 42 after rotation.

[0033] The rubber side piece 45 and the hemispherical protrusion 46 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed.

[0034] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
