Detailed Implementation

[0018] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0019] like Figures 1-7 As shown, a hanger rack for drying automotive parts includes a hanging rod 1. A T-slot 2 is machined on one side wall of the hanging rod 1, extending from top to bottom along the length of the hanging rod 1. Several sliders 3 are installed in the T-slot 2, and the sliders 3 slide in the T-slot 2 to adjust their positions to accommodate different automotive parts. After the sliders 3 are adjusted into position in the T-slot 2, their positions need to be fixed. Specifically, positioning holes 4 are machined on both side walls of the wide groove of the T-slot 2, with multiple positioning holes 4 on each side, evenly distributed along the length of the hanging rod 1. A positioning mechanism is installed on the sliders 3, which cooperates with the positioning holes 4 to fix the position of the sliders 3 in the T-slot 2. A crossbar 6 is installed on the sliders 3, and the crossbar 6 is detachably connected to the sliders 3. Hooks 8 can be installed on the crossbar 6 to suspend the automotive parts.

[0020] like Figures 3-6As shown, the slider 3 has a hollow cavity 5 machined inside. The positioning mechanism is installed inside the cavity 5. The positioning mechanism includes a gear 9, a rack 10, and a knob 11. The gear 9 is installed inside the cavity 5 through a bearing and can rotate relative to the slider 3. There are two racks 10, which are located on the upper and lower sides of the gear 9, respectively. Both racks 10 mesh with the gear 9. The rotation of the gear 9 can drive the two racks 10 to move in opposite directions. A positioning rod 12 is machined at one end of the rack 10. The end of the positioning rod 12 away from the rack 10 penetrates and is connected to the side wall of the cavity 5. It can extend out to the outside of the slider 3 as the rack 10 moves and be inserted into the positioning hole 4 for positioning, or retract into the inside of the slider 3 to release the insertion from the positioning hole 4. The knob 11 is installed on the outside of the slider 3. One end of the knob 11 extends into the cavity 5 and is fixed to the gear 9. The rotation of the gear 9 is achieved by the knob 11, which saves effort. After installation, the positioning rods 12 on the two racks 10 are in opposite directions and the two racks 10 are distributed in parallel. The distance between the axes of the two positioning rods 12 is an integer multiple of the distance between the axes of two adjacent positioning holes 4 on the hanging rod 1, so that during the adjustment of the slider 3, the positioning rods 12 on both sides of the slider 3 can always correspond to the positioning holes 4, ensuring reliable positioning. A countersunk hole 13 is machined at the end of the rack 10 away from the positioning rod 12. A first spring 14 is installed inside the countersunk hole 13. The first spring 14 abuts against the side wall of the cavity 5 of the rack 10 and the slider 3. The first spring 14 applies a pushing force to the rack 10, causing the rack 10 to tend to extend outward towards the slider 3, which can ensure the reliable insertion of the positioning rod 12 into the positioning hole 4.

[0021] like Figures 1-3 and Figure 7 As shown, the connection between the slider 3 and the crossbar 6 is a plug-in method, which makes installation and disassembly convenient and quick. A plug-in groove 15 is machined on the side wall of the slider 3 on the same side as the knob 11. A plug-in block 16 is machined on the crossbar 6. The plug-in block 16 is located in the middle of the crossbar 6. The plug-in block 16 is inserted into the plug-in groove 15 to realize the installation of the crossbar 6 on the slider 3. Multiple spaced hanging grooves 7 are machined on the crossbar 6 along its length. Hooks 8 are installed in the hanging grooves 7 to suspend the parts. The hooks 8 can be randomly adjusted to be installed in different hanging grooves 7, which makes operation and adjustment convenient.

[0022] like Figure 1 and Figure 2As shown, locking teeth 18 are machined on both sides of the narrow groove of the T-slot 2. Multiple locking teeth 18 have grooves evenly distributed along the length of the hanging rod 1, forming a wavy shape after machining. A locking hole 17 is machined on the slider 3, and two locking pins 19 are installed within the locking hole 17. The two locking pins 19 are symmetrically distributed within the locking hole 17 and slide against it. A second spring 20 connects between the two locking pins 19, pushing the two locking pins 19. The pin 19 extends out of the snap-fit ​​hole 17 and into the outside of the slider 3. The end of the snap-fit ​​pin 19 is inserted into the groove of the snap-fit ​​tooth 18 for locking and positioning, which further enhances the stability of the connection between the slider 3 and the hanging rod 1. When the slider 3 is adjusted, a pushing force is applied to the slider 3, so that the snap-fit ​​pin 19 and the snap-fit ​​tooth 18 generate a force that overcomes the elastic force of the second spring 20. This allows the snap-fit ​​pin 19 to retract into the snap-fit ​​hole 17 without affecting the adjustment of the slider 3. After the adjustment is in place, the snap-fit ​​pin 19 extends out again under the action of the second spring 20.

[0023] like Figure 1 As shown, a hook 21 is connected to the top of the hanging rod 1. The entire hanging rack can be lifted and moved by the hook 21 to facilitate subsequent operations such as drying.

[0024] The working principle of this utility model is as follows: Install the sliders 3 sequentially into the T-slots 2 of the hanging rod 1, and adjust the position of the sliders 3 in the T-slots 2 according to the specifications of the parts to be hung and dried. During adjustment, the knob 11 drives the gear 9 to rotate. Through the meshing of the gear 9 and the rack 10, the two racks 10 overcome the force of the first spring 14 and move in opposite directions, causing the positioning rod 12 to retract into the slider 3, disengaging the positioning rod 12 from the positioning hole 4, thereby allowing the slider 3 to slide within the T-slots 2. After adjustment, rotate the knob 11 in the opposite direction, and the gear 9 and racks... The engagement of 10 causes the positioning rod 12 to extend from the slider 3 and be inserted into the positioning holes 4 on both sides. The first spring 14 generates a pushing force on the rack 10 to maintain reliable insertion. The second spring 20 pushes the locking pins 19 on both sides to engage in the corresponding locking teeth 18, enhancing the stability of the connection between the slider 3 and the hanging rod 1. The insertion block 16 is inserted into the insertion slot 15 to connect the crossbar 6 to the slider 3. The hook 8 is installed in the hanging slot 7 of the crossbar 6 to suspend the car parts on the hook 8. The whole assembly is lifted and moved to the drying station for drying by the hook 21.
