[0013] 1. This type of telescopic curtain box, through the setting of an adjustment mechanism, allows for the adjustment of the distance between the two secondary boxes (sub-box one and sub-box two) on both sides of the main curtain box to lengthen or shorten the overall length. First, by pulling the cross block, the limiting block connected to the cross block disengages from the slot and the limiting groove. Simultaneously, the gear two connected to the other side of the limiting block disengages from the tooth groove. At this time, an external device with a matching tooth groove is inserted and rotated, driving the rotating shaft to rotate. The rotating shaft then drives the gear one connected to its outer surface to rotate. The rack two and rack one, which are meshed on the upper and lower sides of the outer surface of gear one, move towards or away from each other under the drive of gear one. Due to the movement of one side of sub-box two... The side of the rack is connected to the side of the second rack, and the side of the first auxiliary box is connected to the side of the first rack, thereby driving the second auxiliary box and the second auxiliary box to move closer or further away inside the main curtain box, thereby adjusting the length of the overall device. After adjustment, the limiting block is inserted into the limiting groove and the slot, and the second gear on one side of the limiting block is inserted into the tooth groove, thereby limiting the determined length for subsequent use. This structure allows the length of the curtain box to be adjusted according to actual needs, so as to facilitate installation. Moreover, the telescopic curtain box is more in line with actual needs, eliminating the need to measure and customize a curtain box of the appropriate length.

[0014] 2. This type of retractable curtain box, with its adhesive and mounting plates, allows for easy installation. First, the adhesive plate is pasted into the mounting groove on the back of the main curtain box. The main curtain box is then attached to the wall using the adhesive plate. The length of the curtain box is adjusted using an adjustment mechanism. After adjustment, the mounting plates on both sides of the secondary curtain boxes move to their corresponding positions. The entire assembly is then fixed to the wall using the mounting holes on the mounting plates and matching bolts. This structure allows for easy adjustment of the curtain box length through a simple fixing method to meet construction requirements. Further fixing of the curtain box enhances the connection strength between the curtain box and the wall, ensuring its proper use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 and Figure 3A retractable curtain box includes: a main curtain box 1, an adjusting mechanism 4 on the main curtain box 1, side grooves 21 and 22 respectively on the inner sides of the main curtain box 1, and auxiliary boxes 2 and 3 respectively slidably connected to the inner sides of the main curtain box 1. The interior of side groove 21 is slidably connected to one side of auxiliary boxes 2 and 3, and the interior of side groove 22 is slidably connected to the other side of auxiliary boxes 2 and 3. The adjusting mechanism 4 includes a rotating shaft 20, a gear 8, a rack 10 and a rack 9. The outer surface of the rotating shaft 20 is rotatably engaged with the interior of side groove 22. The interior of gear 8 is fixedly connected to one end of the rotating shaft 20 inside the side groove 22. One side of rack 210 is fixedly connected to the upper side of the side of auxiliary box 23. One side of rack 9 is fixedly connected to the lower side of the side of auxiliary box 2. The opposite sides of rack 9 and rack 210 mesh with the outer surface of gear 8. A limiting groove 17 is opened on the outer side of the main curtain box 1. A slot 16 is opened on the inner side of the limiting groove 17. A limiting round block 15 is inserted into the limiting groove 17. The outer extension of the limiting round block 15 is inserted into the inside of the slot 16. A toothed groove 19 is opened at the end of the rotating shaft 20. The toothed groove 19 meshes with a toothed part. Gear 2 18 is fixedly connected to the inner side of the limiting block 15 on its outer side. A cross block 13 is fixedly connected to the outer side of the limiting block 15. The length of the curtain box is adjusted by pulling the cross block 13, causing the limiting block 15 connected to the cross block 13 to disengage from the slot 16 and the limiting groove 17. At the same time, gear 2 18 connected to the other side of the limiting block 15 disengages from the tooth groove 19. At this time, an external device that matches the tooth groove 19 is inserted and rotated, which drives the rotating shaft 20 to rotate. The rotating shaft 20 then drives gear 1 8 connected to its outer surface to rotate, meshing with the upper and lower sides of the outer surface of gear 1 8. The connected racks 10 and 9 move towards or away from each other under the drive of gear 8. Since one side of the secondary box 3 is connected to the side of the rack 10 and one side of the secondary box 2 is connected to the side of the rack 9, the secondary boxes 2 and 3 move closer or further away from each other inside the main curtain box 1, thereby adjusting the length of the overall device. After adjustment, the limiting block 15 is inserted into the limiting groove 17 and the slot 16. At the same time, the gear 18 on one side of the limiting block 15 is inserted into the tooth groove 19, thereby limiting the determined length for subsequent use.

[0022] Please see Figure 1 and Figure 2The main curtain box 1 has a mounting groove 23 on its rear side, and an adhesive plate 7 is pasted inside the mounting groove 23. The rear ends of the secondary curtain box 1 2 and secondary curtain box 2 3 are fixedly connected to mounting plates 5. The mounting plate 5 has a through mounting hole 6 in the middle. By pasting the adhesive plate 7 into the mounting groove 23 on the rear side of the main curtain box 1 and determining the installation position, the main curtain box 1 is pasted to the wall with the adhesive plate 7. The length of the curtain box is adjusted by the adjustment mechanism 4. After the adjustment is completed, the mounting plates 5 on both sides of the secondary curtain box 1 2 and secondary curtain box 2 3 are also moved to the corresponding positions. At this time, the entire device can be fixed to the wall with the mounting holes 6 on the mounting plates 5 and the matching bolts.

[0023] Please see Figure 3 Both ends of the opposite sides of rack 19 and rack 210 are fixedly connected with limiting plates 11. The sides of rack 210 and rack 19 are in contact with the inner upper and lower surfaces of side groove 22. The limiting plates 11 are set to prevent rack 19 and rack 210 from moving excessively, causing secondary boxes 12 and secondary boxes 23 to detach from the main curtain box 1.

[0024] Please see Figure 3 and Figure 4 The two auxiliary boxes 2 and 3 each have a semi-circular groove 14 on their opposite sides. The end of the rotating shaft 20 is fixedly connected to a limiting circular plate 12. One side of the limiting circular plate 12 is in contact with the inner side of the rack 2 10 and rack 1 9. The internal size of the semi-circular groove 14 is the same as the external size of the limiting circular plate 12. The limiting circular plate 12 is set to prevent the rotating shaft 20 from detaching from the main curtain box 1 and to ensure the normal operation of the device.

[0025] Working principle: When using the system, firstly, when installing the whole system, firstly, stick the adhesive board 7 inside the mounting groove 23 opened on the back side of the main curtain box 1, and then determine the installation position and stick the main curtain box 1 to the wall using the adhesive board 7.

[0026] At this time, the length of the curtain box is adjusted by adjusting mechanism 4. By pulling the cross block 13, the limiting block 15 connected to the cross block 13 disengages from the slot 16 and the limiting groove 17. At the same time, the gear 18 connected to the other side of the limiting block 15 disengages from the tooth groove 19. At this time, an external device that matches the tooth groove 19 is inserted and rotated, which drives the rotating shaft 20 to rotate. The rotating shaft 20 then drives the gear 8 connected to its outer surface to rotate. The racks 10 and 9, which are meshed with the upper and lower sides of the outer surface of the gear 8, are driven by the gear 8. The movement of the auxiliary box 2 3 towards or away from each other is caused by the connection of one side of the auxiliary box 2 3 to the side of the rack 2 10 and one side of the auxiliary box 1 2 to the side of the rack 1 9. This causes the auxiliary boxes 1 2 and 2 3 to move closer or further away from each other inside the main curtain box 1, thereby adjusting the length of the overall device. After adjustment, the limiting block 15 is inserted into the limiting groove 17 and the slot 16. At the same time, the gear 2 18 set on one side of the limiting block 15 is inserted into the tooth groove 19, thereby limiting the determined length for subsequent use.

[0027] After adjustment, the mounting plates 5 on both sides of the auxiliary boxes 1 2 and 2 3 are also moved to the corresponding positions. At this time, the entire device can be fixed to the wall through the mounting holes 6 opened on the mounting plates 5 and the matching bolts.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
