[0006] A further improvement of the utility model is that a guide tube connected to the pin hole is provided at one end of the fixed base for inserting the positioning pin, and the diameter of the guide tube is adapted to the aperture of the reserved hole of the frame so that the guide tube can pass through the reserved hole of the frame; guide openings corresponding to the limiting boss are respectively opened on both sides of the guide tube, that is, the positioning pin is inserted into the pin hole after passing through the guide tube, and the limiting boss is movably inserted in the guide opening.

[0007] A further improvement of the utility model is that the fixed base is cylindrical, the pin hole is a through structure, and the pin hole is coaxial with the fixed base.

[0008] A further improvement of the utility model is that strap guide grooves corresponding to the strap guide holes are provided on both sides of the pin hole, and the strap guide holes, the strap guide grooves and the pin hole are communicated with each other.

[0023] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] Please refer to the attached Figure 1 — Figure 3, combined with a specific embodiment, it is explained as follows: a frame tube harness positioning and restraining device described in the utility model comprises a fixed base 1, a positioning pin 2 and a cable tie 4; the fixed base 1 is a cylindrical structure, and a pin hole is opened on the fixed base 1, and the positioning pin 2 passes through the reserved hole of the frame and is movably inserted into the pin hole; the pin hole is a through structure, and the pin hole is coaxial with the fixed base 1; one end of the fixed base 1 for inserting the positioning pin 2 is provided with a guide tube 1-1 connected to the pin hole, and the diameter of the guide tube 1-1 is adapted to the aperture of the reserved hole of the frame, so that the guide tube 1-1 can pass through the reserved hole of the frame, that is, the positioning pin 2 passes through the guide tube 1-1 and is inserted into the pin hole.

[0025] Both sides of the fixed base 1 are respectively provided with cable tie guide holes 1-2, which are connected with the pin holes; both sides of one end of the positioning pin 2 inserted into the pin hole are respectively provided with cable tie openings 2-2, and the cable tie openings 2-2 on both sides are connected with each other; both sides of the positioning pin 2 are respectively connected with limiting bosses 2-1 extending to the outside of the reserved hole of the frame, and both sides of the guide tube 1-1 are respectively provided with guide openings 1-4 corresponding to the limiting bosses 1-2, the limiting bosses 2-1 are movably inserted in the guide openings 1-4, and the limiting bosses 2-1 cooperate with the fixed base 1 to clamp the frame 3.

[0026] Specifically, the limiting boss 2-1 is a right-angled triangle structure and is made of elastic material; one horizontal surface of the right-angled triangle is connected to the positioning pin 2, and the other horizontal surface of the right-angled triangle faces the closed end of the positioning pin 2; when the positioning pin 2 is inserted into the reserved hole of the frame, the inclined surface of the limiting boss 2-1 faces the frame, and at this time the inclined surface is equivalent to a guide surface. Since the limiting boss 2-1 is made of elastic material, the limiting boss 2-1 is deformed after being squeezed by the reserved hole of the frame so that it can pass through the frame hole. After passing through the reserved hole of the frame, the limiting boss 2-1 automatically rebounds and resets, and the limiting boss 2-1 exits.

[0027] The cable tie 4 is inserted through the cable tie guide hole 1-2 on one side of the fixed base 1, and then passes through the cable tie openings 2-2 on both sides of the positioning pin 2 and then passes through the cable tie guide hole 1-2 on the other side of the fixed base 1, thereby fastening the fixed base 1 and the positioning pin 2.

[0028] The use principle of this utility model: refer to Figure 4 The fixed base 1 and the positioning pin 2 are pre-connected together by using a cable tie 4 through the cable tie guide hole 1-2 and the cable tie opening 2-2, and the limiting boss 2-1 of the positioning pin 2 is not within the guide opening 1-4 of the fixed base 1, so that the right-angle side of the limiting boss 2-1 supports the end of the guide tube 1-1, and the pre-installation is completed.

[0029] Reference Figure 5When fixing the wiring harness, first pass the pre-installed fixed base 1, positioning pin 2 and cable tie 4 assembly through the limited boss 2-1 of the positioning pin 2 through the reserved hole of the frame, and hear a "snap" sound when the limited boss 2-1 is freely opened. At this time, rotate the positioning pin 2 so that the limited boss 2-1 of the positioning pin 2 enters the guide opening 1-4 of the fixed base 1, bring the wiring harness close to the outer end of the fixed base 1, and tie the wiring harness with the cable tie 4. At this time, the fixed base 1 is freely rotated in the reserved hole of the frame to a most suitable position. While tightening it with the cable tie 4, the limited boss 2-1 of the positioning pin 2 and the inner end of the fixed base 1 will tightly clamp the frame, and the installation is completed.

[0030] In one embodiment, a tie guide groove 1-5 corresponding to the tie guide hole 1-2 is provided on both sides of the pin hole, and the tie guide hole 1-2, the tie guide groove 1-5 and the pin hole are connected to each other. After the tie 4 passes through the tie guide hole 1-2, it can be placed in the tie guide groove 1-5. This structure enables the positioning pin 2 to be better inserted into the pin hole.

[0031] In one embodiment, at least two cable tie guide holes 1-2 form a group and are evenly spaced and arranged. The staff can select cable tie guide holes at different positions according to the actual installation situation, which greatly improves the adaptability of the device.

[0032] In one embodiment, the positioning pin 2 is a cylindrical structure, the tie openings 2-2 are arranged on both sides of the closed end of the positioning pin, and the limiting boss 2-1 is close to the open end of the positioning pin 2. With the above structure, the weight of the positioning pin 2 can be reduced.

[0033] In one embodiment, the side of the cable tie opening 2-2 facing the closed end of the positioning pin is a concave structure. The concave structure can facilitate the staff to wear the cable tie 4.

[0034] In one embodiment, a plurality of grooves are evenly arranged on the outer surface of the fixed base 1; observation windows 1-3 are provided at the bottom of the grooves. The arrangement of the grooves can not only reduce the weight of the fixed base 1, but also improve the structural strength of the fixed base 1. At the same time, the staff can observe the installation of the cable tie 4 at any time through the observation windows 1-5, which is conducive to the installation of the cable tie 4.
