Description

Technical Field

[0001] This utility model relates to the field of rolled tubes, specifically a snap-fit ​​rolled tube. Background Technology

[0002] In existing technologies or within the industry, splicing ultra-long hoses relies on connecting rods inside the hose to secure the two sections. However, this existing technology has the following shortcomings:

[0003] First, the spliced ​​surface of the roll tube cannot be precisely fixed, resulting in discontinuities on the surface, which causes indentations when the fabric is rolled up, damaging the flatness of the fabric.

[0004] Secondly, when one end of the fabric is inserted into the roller tube slot for fixation, the slot gap is small and the roller tube is too long, making operation difficult and easily causing scratches on the fabric and damaging the roller blind system. Utility Model Content

[0005] The purpose of this invention is to provide a snap-fit ​​type reel to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A snap-fit ​​hose includes a hose with grooves on both the upper and lower parts of its outer wall. An extension plate is provided on the upper part of the groove opening. The extension plate is fixedly connected to one end of the hose near the groove. A top strip is fixedly connected to the left side of the upper surface of the groove. A rotating shaft is installed at the end of the hose away from the extension plate. An arc-shaped plate is fixedly connected to the outer wall of the rotating shaft. A bottom strip is fixedly connected to the lower surface of the arc-shaped plate.

[0008] As a further embodiment of this utility model: the top of the top strip is fixedly connected to the first inclined piece, and the bottom of the bottom strip is fixedly connected to the second inclined piece, wherein the first inclined piece and the second inclined piece are connected at an angle.

[0009] As a further improvement of this utility model: a round head is fixedly connected to one end of the arc plate near the rotating shaft, and an arc groove is formed on the side of the round head near the round head.

[0010] As a further improvement of this utility model: the lower part of the round head is provided with an arc-shaped opening, which is adapted to the round head.

[0011] As a further embodiment of this utility model: a roller blind mounting block is installed between the groove and the top strip, and a curtain strip is installed on the lower part of the roller blind mounting block.

[0012] As a further embodiment of this utility model: both ends of the coiled tube are threaded with threaded nuts, and the end of the threaded nut away from the coiled tube is fixedly connected to a fixing disc.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this utility model, the rotating shaft and the arc plate are fixed at one end of the tube. The arc plate can be pressed down onto the groove, and the round head and the arc opening on the arc hook fixed at the lower part of the arc plate are adapted to each other. When the arc plate is pressed down, the round head can slide smoothly in the arc opening.

[0015] In this utility model, the inclined plate 2 connected to the bottom of the round head and the inclined plate 1 at the top of the top strip are in contact with each other. When the lower part of the inclined plate 2 contacts the lower part of the inclined plate 1, the round head is secured to the top strip 1, ensuring the stability of the roller shutter mounting block after connection in the groove, thereby achieving high-precision positioning and preventing discontinuity on the surface of the roller tube.

[0021] 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.

[0022] Please see Figures 1-2In this embodiment of the utility model, a snap-fit ​​roller tube includes a roller tube 1. Grooves 2 are provided on the upper and lower parts of the outer wall of the roller tube 1. An extension plate 12 is provided on the upper part of the groove of the groove 2. The extension plate 12 is fixedly connected to one end of the roller tube 1 near the groove 2. A top strip 4 is fixedly connected to the left side of the upper surface of the groove 2. A rotating shaft 7 is installed on the end of the roller tube 1 away from the extension plate 12. An arc plate 8 is fixedly connected to the outer wall of the rotating shaft 7. When the roller shutter mounting block 3 is placed in the groove 2, the arc plate 8 is in the open state. The arc plate 8 is pressed down onto the groove 2, and the arc plate 8 squeezes the roller shutter mounting block 3 so that it is stably embedded in the groove. A bottom strip 5 is fixedly connected to the lower surface of the arc plate 8.

[0023] The lower part of the round head 9 is provided with an arc opening 10, which is adapted to the round head 9. The arc structure of the arc opening 10 and the sliding fit of the round head 9 allow for a certain installation error and improve the assembly tolerance. The round head 9 at the bottom of the arc plate 8 is adapted to the arc opening 10 on the arc hook 6. When pressed down, the round head 9 slides smoothly in the arc opening 10 to ensure accurate positioning trajectory.

[0024] Please see Figures 1-2 The top of the top strip 4 is fixedly connected to the inclined plate 13, and the bottom of the bottom strip 5 is fixedly connected to the inclined plate 25. The inclined plate 13 and the inclined plate 25 are connected at an angle. When the roller blind mounting block 3 is placed in the groove 2, the arc plate 8 is in the open position. The elastic design of the arc plate 8 can be supplemented with springs to adapt to roller blind mounting blocks of different sizes without manual adjustment. After the arc plate 8 is pressed down on the groove 2, the roller blind mounting block 3 can be squeezed and limited to ensure that the roller blind mounting block 3 is in the groove 2. The inclined plate 25 at the bottom of the round head 9 contacts the inclined plate 13 at the top of the top strip 4. The inclined surface design of the two pushes the round head 9 downward to the top strip 4, forming a mechanical lock. Through the contact of the inclined surfaces of the inclined plates, the position of the round head 9 is automatically adjusted to ensure that the roller blind mounting block 3 does not shift in the groove 2 and eliminates splicing gaps.

[0025] Please see Figures 1-2 A round head 9 is fixedly connected to one end of the arc plate 8 near the rotating shaft 7. An arc groove is opened on one side of the round head 9 near the round head 9. The rotating shaft 7 is fixed to the arc plate 8, and the rotational transmission ensures that the arc plate moves smoothly.

[0026] Please see Figures 1-3 A roller blind mounting block 3 is installed between the groove 2 and the top strip 4. A curtain strip is installed on the lower part of the roller blind mounting block 3. The inclined plate 15 connected to the bottom of the round head 9 and the inclined plate 13 at the top of the top strip 4 are in contact with each other. When the lower part of the inclined plate 15 and the inclined plate 13 are in contact, the round head 9 is fastened to the top strip 4, which ensures the stability of the roller blind mounting block 3 after connection in the groove 2, thereby achieving high-precision positioning. The top strip 4 and the groove 2 form upper and lower limits to prevent the roller blind mounting block 3 from loosening in the vertical direction.

[0027] Please see Figure 3 Both ends of the coil tube 1 are threaded with threaded nuts 11. The end of the threaded nut 11 away from the coil tube 1 is fixedly connected with a fixing plate 14 to prevent the surface of the coil tube from being discontinuous, thus overcoming the technical problem of discontinuity in splicing ultra-long coil tubes.

[0028] The working principle of this utility model is as follows:

[0029] When in use, place the roller shutter mounting block 3 into the groove 2. At this time, the arc plate 8 is in the open state. After pressing the arc plate 8 down onto the groove 2, the roller shutter mounting block 3 can be squeezed and limited to ensure that the roller shutter mounting block 3 is in the groove 2.

[0030] The rotating shaft 7 and the arc plate 8 installed at one end of the tube 1 are fixed. The arc plate 8 can be pressed down onto the groove 2. The round head 9 fixed at the lower part of the arc plate 8 and the arc opening 10 on the arc hook 6 are adapted to each other. When the arc plate 8 is pressed down, the round head 9 can slide smoothly in the arc opening 10.

[0031] The inclined plate 15 connected to the bottom of the round head 9 and the inclined plate 13 at the top of the top strip 4 are in contact with each other. When the lower part of the inclined plate 15 and the inclined plate 13 are in contact, the round head 9 is fastened to the top strip 4, which ensures the stability of the roller shutter mounting block 3 after connection in the groove 2, thereby achieving high-precision positioning and preventing the roller tube surface from having a break, thus overcoming the technical problem of the break in the splicing of ultra-long roller tubes.

[0032] Installation: Place the roller shutter mounting block 3 in the groove 2, manually press down the arc plate 8 to make it fit the upper surface of the groove 2, and squeeze the roller shutter mounting block 3; During the pressing down of the arc plate 8, the round head 9 slides along the arc opening 10 of the arc hook 6; the inclined plate 2 15 contacts the inclined surface of the inclined plate 13, push the round head 9 to engage with the top strip 4, and complete the positioning;

[0033] Adjustment: When the arc plate 8 is pressed down, the round head 9 slides in the arc opening 10, automatically adapting to the positional deviation of the installation block; the pressure generated by the contact of the inclined plate makes the round head 9 accurately embedded in the top strip 4, forming a stable lock. Through the uniform extrusion of the arc plate 8 and the sliding positioning of the round head and the arc opening, it is ensured that the adjacent roller blind installation blocks 3 are aligned in the groove 2, eliminating the height difference at the splicing point.
