[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0021] See also Figure 1-5 , an embodiment provided by the utility model:

[0022] A hidden cloth threading structure comprises a slotted tube 1 and a cloth piece 3. The slotted tube 1 is provided with two groups. The surfaces of the two groups of slotted tubes 1 are provided with slide grooves 2. The cloth piece 3 can slide in the slide grooves 2. The top of the slotted tube 1 is fixedly connected with a back top plug-in iron core 4. The middle part of the slotted tube 1 is abutted and connected with a rear lower transverse tube 5. The lower surfaces of the two groups of slotted tubes 1 are provided with transverse grooves 6. The interior of the transverse grooves 6 is plugged with a front transverse 7. The surface of the front transverse 7 is fixedly connected with a fixing nail 8. The bottom surface of the slotted tube 1 is abutted and connected with a front transverse outer U-shaped iron sheet 9. The surface of the front transverse outer U-shaped iron sheet 9 is movably connected with a self-tapping screw 10. The back top is fixed by an inserting iron core, and the rear lower transverse tube 5 is used in the middle of the back to hold the cloth piece 3 open. The structure is novel and time-saving and labor-saving to install. Compared with the existing cloth-pressing cloth threading method, a hidden cloth threading structure is adopted, and the cloth threading frame is fully enclosed. The appearance is neat and clear, the operation is simple, and the cost is reduced.

[0023] Furthermore, a circular groove 1 is opened at the right end of the slotted tube 1, and the back top inserted iron core 4 passes through the circular groove 1 to fix the cloth piece 3 inside the slide groove 2. The cloth piece 3 is first inserted into the slide groove 2 of the slotted tubes 1 on both sides, and then the cloth piece 3 is fixed by the back top inserted iron core 4 to prevent the cloth piece 3 from slipping off.

[0024] Furthermore, a second circular groove is formed on the opposite surfaces of the middle of the two groups of slotted tubes 1, and both ends of the rear lower transverse tube 5 pass through the second circular groove to connect the two groups of slotted tubes 1, and the rear lower transverse tube 5 stretches the cloth pieces 3 inside the slotted tubes 1.

[0025] Furthermore, the length of the cloth piece 3 is slightly greater than the length of the slotted tube 1 , so that a portion of the cloth piece 3 is still outside the slotted tube 1 after it is fully unfolded inside the slotted tube 1 .

[0026] Furthermore, after the front transverse seat 7 is inserted into the transverse groove 6 , the portion of the cloth piece 3 that is longer than the slotted tube 1 covers the surface of the front transverse seat 7 , and at this time, the cloth piece 3 is completely tightened on the surface of the front transverse seat 7 .

[0027] Furthermore, the fixing pins 8 penetrate the cloth piece 3 and are fixedly connected to the surface of the front crossbar 7 of the seat, and the friction between the taut cloth piece 3 and the cross groove 6 and the front crossbar 7 of the seat prevents the front crossbar 7 from sliding downward.

[0028] Furthermore, a circular groove three is provided on the surface of the front transverse seat 7, and a circular groove four is provided on the surface of the front transverse outer U-shaped iron sheet 9. Self-tapping screws 10 penetrate circular groove three and circular groove four to fix the front transverse outer U-shaped iron sheet 9, the cloth piece 3 and the front transverse seat 7 together, so that the front transverse outer U-shaped iron sheet 9 is locked on the surface of the cloth piece 3 and the front transverse seat 7.

[0029] Working principle: When using the hidden cloth-threading structure, first pass the cloth piece 3 through the slide groove 2 in the slotted tube 1 to the top of the slotted tube 1, use the back top insertion iron core 4 to pass through the circular groove 1 opened at the right end of the slotted tube 1 and insert it into the top opening of the cloth piece 3, fix it with the top of the slotted tube 1, insert the rear lower horizontal tube 5 into the circular groove 2 opened on the opposite surface of the middle part of the slotted tube 1, stretch and tighten the cloth piece 3, insert the front horizontal tube 7 into the horizontal groove 6, the part of the cloth piece 3 longer than the slotted tube 1 covers the surface of the front horizontal tube 7, use the fixing nail 8 to fix the cloth piece 3 on the surface of the front horizontal tube 7, at this time, the cloth piece 3 moves with the opening The groove tube 1 is shaped and tightened, and the front horizontal outer U-shaped iron sheet 9 is fixed to the surface of the front horizontal seat 7 by self-tapping screws 10. The friction between the tightened cloth piece 3 and the horizontal groove 6 and the front horizontal seat 7 prevents the front horizontal seat 7 and the front horizontal outer U-shaped iron sheet 9 from sliding down, completing the assembly of the structure. The top of the back is fixed with an iron core, and the rear lower horizontal tube 5 of the seat is used to open the slide groove 2 in the middle of the back. The structure is novel and time-saving and labor-saving to install. Compared with the existing cloth-pressing cloth-threading method, a hidden cloth-threading structure is adopted, and the cloth-threading frame is fully enclosed, the appearance is neat and clear, the operation is simple, and the cost is reduced.
