Description

Technical Field

[0001] This utility model relates to the field of sleeve technology, specifically to a rolling sleeve and a sliding hinge with the sleeve. Background Technology

[0002] The sliding sleeve is one of the folding components of many deformable folding products. The sliding sleeve is slidably sleeved on the outside of the rod. The sliding stroke of the sleeve on the rod is used to complete the folding and unfolding of the product. When the existing sliding sleeve and the rod are in a guide rail-less sliding fit, the frictional resistance generated is large, which not only affects the folding effect of the product, but also easily causes wear to the rod. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a rolling sleeve and a sliding hinge with the sleeve.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a rolling sleeve, including a cylinder body, wherein at least one end of the cylinder body is engaged with a retaining ring, the retaining ring including a ring body and a flange located at the top of the ring body and extending inward;

[0005] The rolling mechanism includes a limiting groove disposed on the end of the cylinder or the flange and a rolling element limited within the limiting groove. The top of the limiting groove is open for the rolling element to be inserted. The limiting groove has a notch in the direction of the inner wall of the cylinder for the portion of the rolling element to be inserted to protrude from the inner wall of the cylinder.

[0006] Furthermore, the rolling element is a ball or a roller.

[0007] Furthermore, when the rolling element is a ball, the limiting groove includes multiple mounting seats disposed on the flange, the end of the cylinder is provided with a notch for the mounting seat to engage, and the mounting seat is provided with a ball groove for mounting the ball.

[0008] Furthermore, the inner sidewall of the ring is provided with a guide groove corresponding to the ball groove for adapting to the ball.

[0009] Furthermore, when the rolling element is a ball and the rolling element is disposed at the end of the cylinder, the limiting groove includes a plurality of ball grooves disposed at the end of the cylinder.

[0010] Furthermore, when the rolling element is a roller, the limiting groove includes mounting grooves provided at both ends of the cylinder for mounting the roller.

[0011] Furthermore, the side wall of the mounting groove located on the outer side of the cylinder is higher than the side wall located on the inner side of the cylinder.

[0012] A sliding hinge component includes the aforementioned rolling sleeve, wherein the sleeve has a hinge portion for hinged rods along at least one side of its peripheral wall.

[0013] Furthermore, the hinge portion includes two side plates spaced apart on the cylinder and a horizontal plate for connecting the two side plates, and the side plates are provided with pin holes for the pin shaft to pass through.

[0014] Furthermore, it also includes a reinforcement structure for reinforcing the hinge portion, the reinforcement structure including a vertical plate disposed on the horizontal plate, and a connecting plate disposed between the vertical plate and the adjacent side plate;

[0015] A reinforcing plate for reinforcement is provided between adjacent hinge parts, and the reinforcing plate is provided with mounting holes.

[0016] Compared with the prior art, this utility model has the following beneficial effects:

[0017] This invention, by incorporating a rolling element inside the sleeve, transforms the sleeve's movement on the rod from sliding to rolling. This reduces friction during movement, improves the folding and unfolding effect of the product, and avoids wear on the rod caused by long-term sliding friction, thereby enhancing product quality and lifespan.

[0018] This utility model's sleeve comprises a separate cylindrical body and a retaining ring. Whether the rolling mechanism is located on the cylindrical body or the retaining ring, the assembly of the rolling components is more convenient. For example, when the limiting groove on the retaining ring is a ball groove, since the ball groove is open at the top, when installing the ball, simply place the retaining ring into the container containing the ball. After the ball groove is submerged, the ball automatically engages in the ball groove. Then, remove the retaining ring and snap the sleeve body into the retaining ring to complete the ball's limiting assembly, which is very convenient. Conversely, the same operating principle applies when the limiting groove is located on the sleeve body. Attached Figure Description

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Please see Figure 1-11 .

[0034] Example 1:

[0035] Please see Figure 1-5The present invention relates to a rolling sleeve, comprising a cylinder body 1, characterized in that a retaining ring 2 is engaged at least at one end of the cylinder body 1, the retaining ring 2 comprising a ring body 21 and a flange 22 located at the top end of the ring body 21 and extending inward, and disposed at both ends of the cylinder body 1.

[0036] The rolling mechanism 3 includes a limiting groove 31 disposed on the end of the cylinder 1 or the flange 2 and a rolling element 32 limited in the limiting groove 31. The top of the limiting groove 31 is open for the rolling element 32 to be inserted. The limiting groove 31 is provided with a notch 312 in the direction of the inner wall of the cylinder 1 for the part of the rolling element 32 to be inserted to protrude from the inner wall of the cylinder 1.

[0037] By providing a rolling element 32 inside the cylinder 1, and having the rolling element 32 protrude from the flange 22 and the inner side of the cylinder 1, it is possible to avoid significant friction between the cylinder 1 and the rod when the cylinder 1 is fitted inside the rod. Through the contact between the rolling element 32 and the rod, the rigid friction between the rod and the cylinder 1 is transformed into rolling friction between the rolling element 32 and the rod. By providing a limiting groove 31, the rolling element 32 can be slidably and limited between the cylinder 1 and the retaining ring 2. By having the rolling element 32 protrude from the inner wall of the cylinder 1, it is possible to ensure that when the rolling element 32 contacts the rod, the cylinder 1 and the rod do not contact each other.

[0038] It should be noted that when the rolling element 32 is a ball bearing 321, the limiting groove 31 includes multiple mounting seats 311 disposed on the flange 22. The end of the cylinder 1 is provided with a notch 312 corresponding to the mounting seat 311 for engaging with the mounting seat 311. The mounting seat 311 contains a ball groove 313 for mounting the ball bearing 321. This design, by providing the mounting seat 311 and the notch 312, facilitates the detachable mounting of the retaining ring 2 onto the cylinder 1. By providing the ball groove 313 on the mounting seat 311, it is easy to install the ball bearing 321 within the mounting seat 311, and the ball bearing 321 can protrude from the cylinder 1, allowing it to contact the rod during use. Furthermore, considering the structure of the ring 21, such as... Figure 3 As shown, the advantage of this design is that it makes it easy to put the ball bearings 321 into the ball grooves 313. By placing the ring body 21 into the box containing a large number of ball bearings 321, then pressing the ring body 21 down to completely submerge it in the ball bearings 321, and then lifting the ring body 21, all the ball grooves 313 are now filled with ball bearings 321. This can quickly solve the efficiency problem of manually loading the ball bearings 321.

[0039] It should be noted that the inner wall of the ring 21 is provided with a guide groove 314 corresponding to the ball groove 313 for fitting the ball 321. This design, by providing the guide groove 314 on the inner wall of the ring 21 corresponding to the ball groove 313, guides the ball 321 when it is placed into the ball groove 313, thus ensuring that when the ring 21 is lifted, only the ball 321 remains within the ball groove 313.

[0040] Example 2:

[0041] Please see Figure 6 A sliding hinge component includes the aforementioned rolling sleeve, wherein the sleeve 1 has a hinge portion 4 for hinged rods along at least one side of its peripheral wall. This design facilitates the use of the sliding hinge component by providing a hinge portion 4 on at least one side of the sleeve 1, enabling convenient hinged connection with rods.

[0042] It should be noted that the hinge part 4 includes two side plates 42 spaced apart on the cylinder 1 and a horizontal plate 41 for connecting the two side plates 42. The side plates 42 are provided with pin holes 43 for the pin shaft to pass through. This design, by setting the hinge part 4, facilitates the installation of rods during use and the use of the sleeve. By setting the side plates 42 and the horizontal plate 41, it is convenient for the rod to be rotatably mounted on the hinge part 4 via the pin shaft.

[0043] It should be noted that the reinforcement structure 5 is also included for reinforcing the hinge part 4. The reinforcement structure 5 includes a vertical plate 51 disposed on the horizontal plate 41. A connecting plate 52 is disposed between the vertical plate 51 and the adjacent side plate 42. The connecting plate 52 is provided with a clearance hole 53 for clearance during the installation of the pin.

[0044] A reinforcing plate 54 is provided between adjacent hinge parts 4 for reinforcement, and the reinforcing plate 54 is provided with a hanging hole 55. This design, by providing the reinforcing structure 5, can improve the structural stability of the hinge parts 4 and facilitate the normal use of the hinge parts 4. By providing the reinforcing plate 54, a connection can be established between adjacent hinge parts 4, further improving the structural stability.

[0045] Example 3:

[0046] Please see Figure 7-8 The difference between this embodiment and Embodiment 1 is that when the rolling element 32 is a ball bearing 321 and the rolling element 32 is disposed at the end of the cylinder 1, the limiting groove 31 includes a plurality of ball grooves 313 disposed at both ends of the cylinder 1. This design allows for the installation of the ball bearing 321 by providing ball grooves 313 at both ends of the cylinder 1, and the retaining rings 2 at both ends can cooperate with the cylinder 1 to limit the movement of the ball bearing 321.

[0047] Example 4:

[0048] Please see Figure 9-11 The difference between this embodiment and Embodiment 1 is that when the rolling element 32 is a roller, the limiting groove 31 includes mounting grooves 315 at both ends of the cylinder 1 for mounting the roller. This design, by setting the rolling element 32 as a roller, enables rolling contact with the rod during use. Furthermore, by providing mounting grooves 315 at both ends of the cylinder 1 for mounting the roller, installation of the roller is convenient. Combined with the retaining ring 2, the roller can be limited, ensuring normal use.

[0049] It should be noted that the side wall of the mounting groove 315 located on the outer side of the cylinder 1 is higher than the side wall located on the inner side of the cylinder 1. This design, by setting the side wall of the outer side of the cylinder 1 to be higher than the side wall located on the inner side of the cylinder 1, facilitates the limiting of the roller, thereby preventing the roller from falling out of the cylinder 1 during use.

[0050] Preferably, the flange 22 is provided with a groove for fitting the roller. This design facilitates the installation and positioning of the roller, and also allows for easy rotation of the roller by cooperating with the mounting groove 315 on the cylinder 1.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
