[0017] 1. The utility model realizes the locking and fixing of the sliding wheel mounting seat and the sliding wheel assembly by adopting a locking structure that is squeezed and engaged on both sides. When installing the sliding wheel assembly, the sliding wheel support is first plugged into the positioning hole on the sliding wheel mounting seat through the positioning head at the end of the connecting rod, and then the paddle is toggled to slide the tongue lock toward the inner side of the tongue lock sliding groove, so that the clamping blocks on the side of the tongue lock extend out of the positioning hole and engage with the rectangular clamping grooves on both sides of the positioning head, thereby realizing locking and fixing. When disassembling, the paddle is toggled outward to reset the tongue lock, so that the positioning head can be separated from the positioning hole. The whole process does not require the aid of external tools, and solves the problem that the sliding wheel of the existing sliding door sliding wheel assembly is fixed to the mounting surface by screws, while the sliding wheel is a wearing part. As the use time increases, the surface is prone to wear, generating non-positive force, making the sliding door not smoothly drawn, and the use of a screw-type connection method makes it inconvenient to disassemble and assemble the sliding wheel.

[0018] 2. By installing a weak magnetic suction sheet on the bottom surface of the positioning hole, after the positioning head of the sliding wheel support is inserted into the positioning hole of the sliding wheel mounting seat, the weak magnetic suction sheet can be adsorbed and fixed to the positioning head made of ferrous material through weak magnetic force to achieve the effect of preliminary positioning, which is convenient for further locking later.

[0019] 3. By arranging a rubber limit block fixed by a connecting rope on the sliding wheel mounting seat, after the tongue lock slides to the end of the tongue lock sliding groove and is locked, the rubber limit block can be inserted into the remaining gap of the tongue lock sliding groove to avoid the tongue lock from resetting, thereby further improving the locking stability.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-3 , the utility model provides an embodiment: an extrusion type quick-release sliding door sliding wheel, comprising a sliding wheel mounting seat 1 and a sliding wheel support seat 7;

[0026] Also includes:

[0027] A positioning hole 6, which is arranged at a middle position inside the sliding wheel mounting seat 1;

[0028] The tongue lock sliding groove 3 is arranged on both sides of the positioning hole 6, and the tongue lock 4 is installed inside the tongue lock sliding groove 3. The sides of the tongue lock 4 on both sides are provided with a clamping block 13, and one end of the clamping block 13 passes through and extends to the inside of the positioning hole 6;

[0029] The connecting rod 9 is installed at the lower end of the sliding wheel support 7. A positioning head 11 is installed at the lower end of the connecting rod 9. Rectangular slots 12 are provided on both sides of the outer wall of the positioning head 11. The sliding wheel support 7 is connected to the positioning hole 6 on the sliding wheel mounting seat 1 through the positioning head 11.

[0030] See also Figure 3 A weak magnetic attraction sheet 16 is installed on the bottom surface of the positioning hole 6. After the positioning head 11 of the sliding wheel support 7 is inserted into the positioning hole 6 of the sliding wheel mounting seat 1, the weak magnetic attraction sheet 16 can be adsorbed and fixed to the positioning head 11 made of iron-containing material through weak magnetic force to achieve the effect of preliminary positioning, which is convenient for subsequent further locking.

[0031] See also Figure 1 A paddle 5 is provided at the upper end of the tongue lock 4, and the paddle 5 is integrally formed with the tongue lock 4. The paddle 5 allows a person to manually paddle the tongue lock 4 to slide without the aid of external tools.

[0032] See also Figure 1 and Figure 3 A rubber limit block 14 is provided on one side of the tongue lock 4, and the rubber limit block 14 is located inside the tongue lock sliding groove 3. The rubber limit block 14 is connected to the outer wall of the sliding wheel mounting seat 1 through a connecting rope 15. After the tongue lock 4 slides and is locked, the rubber limit block 14 can be inserted into the remaining gap of the tongue lock sliding groove 3 to prevent the tongue lock 4 from resetting and improve the locking stability.

[0033] See also Figure 1 The sliding wheel support 7 is threadedly connected to the connecting rod 9 through a screw 10. Sliding wheels 8 are installed on both sides of the sliding wheel support 7. Four sliding wheels 8 are provided, and the four sliding wheels 8 are rotatably connected to the sliding wheel support 7 through a rotating shaft. The sliding wheel support 7 realizes sliding guidance through the sliding wheels 8.

[0034] See also Figure 3 Three screw head protection grooves 2 are arranged inside both ends of the sliding wheel mounting seat 1, and screw holes 17 are arranged inside the screw head protection grooves 2. The sliding wheel mounting seat 1 is pre-fixed to the mounting surface through the screw holes 17 and screws. After installation, the screws are located in the screw head protection grooves 2, which has a good shielding effect to ensure the firmness of the installation.

[0035] Working principle: when in use, first fix the sliding wheel mounting seat 1 to the mounting surface through the screw holes 17 at both ends of the sliding wheel mounting seat 1 with the screws. When installing the sliding wheel assembly, first plug the sliding wheel support 7 into the positioning hole 6 on the sliding wheel mounting seat 1 through the positioning head 11 at the end of the connecting rod 9. When plugging in, the weak magnetic suction piece 16 in the positioning hole 6 can be adsorbed and fixed by the positioning head 11 made of ferrous material through weak magnetic force to achieve the effect of preliminary positioning. Then, the paddle 5 is toggled to slide the tongue lock 4 toward the inside of the tongue lock sliding groove 3, so that the block 13 on the side of the tongue lock 4 extends out from the positioning hole 6 and engages with the rectangular grooves 12 on both sides of the positioning head 11 to achieve the locking and fixing of the sliding wheel 8 assembly. After locking, the rubber limit block 14 can be inserted into the remaining gap in the tongue lock sliding groove 3 to avoid the tongue lock 4 from resetting, thereby further improving the locking stability. When disassembling, the rubber limit block 14 is pulled out by the connecting rope 15, and the paddle 5 is toggled outward to reset the tongue lock 4, so that the positioning head 11 can be separated from the positioning hole 6.
