Abstract
Description
Technical Field
[0001] This application relates to the field of product display rack technology, specifically to a rotating mechanism and a shoe rack having the rotating mechanism. Background Technology
[0002] We often see shoe racks used to display shoes in shoe stores. Shoe racks play a crucial role in showcasing shoes, as the merchandise needs to be displayed as prominently as possible to attract customers to stop and admire them before making a purchase. Traditional shoe racks are generally fixed in one piece, but they come in different angles, typically including three specifications: flat, left-tilted, and right-tilted. Stores usually need to stock all three types of shoe racks, changing them as needed. Frequent changes can be inconvenient, and the used shoe racks require additional storage, undoubtedly increasing spare and daily maintenance costs. Therefore, adjustable shoe racks have emerged, such as those in Chinese patents CN209018254U and CN217792330U. CN217792330U has a simple structure, but due to structural limitations ( The diameter of the shoe support rod is relatively small (generally 10mm), making it difficult to perform multi-faceted processing and thus difficult to achieve small-angle adjustment. In CN209018254U, a gear meshing structure is used for limiting, and the minimum adjustment angle can be adjusted by adjusting the number of teeth. However, the structure is complex and difficult to process, resulting in high production costs. Moreover, once the tray part of the existing shoe support is completed, the size is fixed, which is inconvenient. When it is necessary to display shoes with large size differences, shoe supports of the corresponding size will be replaced in order to make the display area look coordinated. This also requires a certain number of shoe supports of different sizes to be stocked, causing some inconvenience in use and increasing operating costs. Summary of the Invention
[0003] In view of this, this application provides a rotating mechanism and a shoe support having the rotating mechanism to solve the technical problems of existing shoe supports being difficult to adjust at small angles, having complex structures, and having non-adjustable sizes.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A rotating mechanism includes a connecting sleeve and a connecting rod. The connecting rod is pluggably installed in the connecting sleeve. The inner wall of the connecting sleeve is provided with at least one limiting rib. The outer circumferential surface of the connecting rod is provided with an angle limiting groove group that cooperates with the limiting rib. The angle limiting groove group includes at least two adjacent angle limiting grooves. After the adjacent angle limiting grooves are processed, they will form a corresponding partition wall. The lengths of the adjacent angle limiting grooves in the axial extension direction are different, and the height of the partition wall in the radial direction is less than the depth of the angle limiting groove.
[0006] Furthermore, the blind end of the angle limiting groove is provided with a dynamic tilting stop surface, and all the dynamic tilting stop surfaces in the same group have the same tilting direction. The end of the limiting rib is provided with a static tilting stop surface that can fit with the dynamic tilting stop surface.
[0007] Furthermore, the inner wall of the connecting sleeve is provided with two limiting ribs that are offset by 180 degrees in the circumferential direction, and the static inclined stop surfaces on the two limiting ribs are symmetrically arranged.
[0008] Furthermore, the angle limiting groove group includes three angle limiting grooves, with the angle limiting groove located in the middle position having the longest length.
[0009] Furthermore, the connecting rod includes a first rod body and a second rod body with successively increasing diameters. The first rod body is movably fitted with the connecting sleeve. An angle limiting groove is provided on the second rod body. A fixing screw is connected to the end of the first rod body. A compression spring provided in the connecting sleeve abuts against the fixing screw, so that the connecting rod can be automatically inserted and reset.
[0010] Furthermore, the radial cross-section of the limiting rib is large at the root and small at the top, and the top of the limiting rib is a circular arc surface.
[0011] Given that this application has already disclosed a technical solution for a rotating mechanism, this application further discloses a technical solution:
[0012] A shoe holder having the aforementioned rotating mechanism includes a hanger connected to a connecting sleeve, a fixed bracket connected to a connecting rod, and an adjustable placement plate disposed on the fixed bracket. The fixed bracket includes a guide rod extending along the length direction and a support plate connected to the side of the guide rod. The adjustable placement plate includes a pair of symmetrically arranged sub-placement plates. Each sub-placement plate includes a first plate body slidably connected to the guide rod and a second plate body slidably disposed on the first plate body along the width direction. The second plate body is slidably engaged with a guide groove located on the support plate. In use, when the pair of sub-placement plates move away from or closer to each other, the second plate body moves away from or closer to the first plate body.
[0013] Furthermore, the adjustable placement plate also includes two connecting rods. One end of the connecting rod is hinged to the corresponding first plate body, and the other end of the two connecting rods is movably connected to the connecting shaft of the adjustment mechanism. The end plate connected to the lower end of the connecting shaft has an elastic locking mechanism, which acts on the support plate.
[0014] Furthermore, the end plate is slidably connected to the limiting frame located on the lower surface of the support plate. The support plate has a slot for the connecting shaft to pass through. A spring and a locking ball are installed in the blind hole on the side of the end plate. The locking ball is held against the limiting frame by the spring. The limiting frame has multiple slots that can cooperate with the locking ball.
[0015] As can be seen from the above technical solution, the advantages of the present invention are:
[0016] 1. The rotating mechanism in this application utilizes multiple adjacent angle limiting grooves of varying lengths in conjunction with limiting ribs to allow the angle of the shoe support to be easily adjusted within a small range. The length difference of the angle limiting grooves creates a thickened position on the corresponding side wall of the angle limiting groove, thereby increasing the strength of the angle limiting groove and thus improving the stability of the shoe support during use.
[0017] 2. The angle limiting groove of the rotating mechanism in this application is a localized machining process, which reduces the machining difficulty of the connecting rod and lowers the machining cost.
[0018] 3. The blind end of the angle limiting groove of the rotating mechanism in this application is provided with a dynamic tilting stop surface, and the limiting rib is provided with a static tilting stop surface. The static tilting stop surface can not only play a guiding role, but also prevent the fixed bracket from rotating in the tilted state through the cooperation of the dynamic tilting stop surface and the static tilting stop surface.
[0019] 4. The rotating mechanism in this application has two sets of symmetrically arranged angle limiting grooves, so that no matter which side the fixed bracket tilts, at least one dynamic tilt stop surface and the static tilt stop surface cooperate to play a stopping structure, so that the fixed bracket can maintain a stable tilting posture.
[0020] 5. The shoe rack in this application has an adjustable placement board, which makes the size of the placement board adjustable to meet the needs of items of different sizes, avoids frequent replacement, reduces inventory, and is simple and convenient to adjust. Attached Figure Description

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.
[0035] refer to Figures 1 to 7 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a rotating mechanism, including a connecting sleeve 2 and a connecting rod 5. The connecting rod 5 is pluggably installed in the connecting sleeve 2. The inner wall of the connecting sleeve 2 is provided with at least one limiting rib 21. The outer circumferential surface of the connecting rod 5 is provided with an angle limiting groove group that cooperates with the limiting rib 21. The angle limiting groove group includes at least two adjacent angle limiting grooves. After the adjacent angle limiting grooves are processed, they will form a corresponding partition wall 524. The lengths of the adjacent angle limiting grooves along the axial extension direction are different, and the height of the partition wall 524 along the radial direction is less than the depth of the angle limiting groove.
[0036] Specifically, the connecting rod 5 includes a first rod body 51 and a second rod body 52 with successively increasing diameters. The first rod body 51 is rotatably connected to the connecting sleeve 2 to form a rotating pair, and the first rod body 51 can move axially along the inner hole of the connecting sleeve 2. An angle limiting groove of the connecting rod 5 is provided on the second rod body 52, and the end of the angle limiting groove near the connecting sleeve 2 extends to the end face of the second rod body 52. After the limiting rib 21 slides into the corresponding angle limiting groove, it forms a stop structure to restrict the relative rotation of the connecting rod 5 and the connecting sleeve 2, so that the connecting rod 5 can be stably maintained in the corresponding state. After the connecting rod 5 and the connecting sleeve 2 are locked together, the friction between the connecting rod 5 and the connecting sleeve 2, or the locking screw or elastic element provided on the connecting sleeve 2 and acting on the connecting rod 5, can be used to prevent the connecting rod 5 from separating from the connecting sleeve 2. When the second rod body 52 separates from the connecting sleeve 2, the connecting rod 5 is in the first position, the limiting rib 21 separates from the angle limiting groove, the connecting rod 5 can rotate freely, and the limiting rib 21 slides into the corresponding angle limiting groove. When the angle limiting groove continues to slide into the connecting rod 5, the connecting rod 5 is in the second position and locked. The connecting rod 5 rotates automatically. The inner hole of the connecting sleeve 2 is stepped. The diameter of the inner hole that mates with the first rod body 51 is smaller than the diameter of the inner hole with the limiting rib 21. Since the radial height of the partition wall 524 is less than the depth of the angle limiting groove, the adjacent angle limiting grooves will overlap to a certain extent, thus enabling small-angle tilt adjustment. Preferably, the adjustment angle between adjacent angle limiting grooves is 15°. However, this results in the technical problem that the partition wall 524 is not strong enough and is prone to deformation. To solve this problem, the lengths of the adjacent angle limiting grooves along the axial extension direction are different. The length difference of the angle limiting grooves makes the corresponding sidewalls of the angle limiting grooves thicker, which improves the local strength of the angle limiting grooves and makes them less prone to deformation. The angle limiting grooves and the limiting rib 21 cooperate stably, improving the stability of the shoe support.
[0037] In the embodiments of this application, such as Figure 3As shown, the end of the first rod 51 is provided with a first threaded hole 511, and the fixing screw 4 is threadedly connected to the first threaded hole 511. The compression spring 3, which is set in the connecting sleeve 2, abuts against the fixing screw 4, so that the connecting rod 5 can be automatically inserted and reset. In this application, the stop is achieved by the cooperation of the limiting rib 21 and the angle limiting groove. The compression spring 3 is used to make the connecting rod 5 automatically reset and maintain a stable locked state. The position of the connecting rod 5 is unlocked by pulling out the connecting rod 5, so that the connecting rod 5 can rotate. When this rotating mechanism is applied to the shoe rack, the connecting rod 5 is connected to the fixed bracket 6, realizing the convenient switching between three states of the adjustable placement plate 7: flat, tilted to the left, and tilted to the right. The compression amount of the compression spring 3 can be adjusted by the fixing screw 4, thereby adjusting the reset elastic force, so that the compression spring 3 can generate sufficient reset tension to reliably insert the connecting rod 5 into the connecting sleeve 2, preventing the connecting rod 5 from being too long and prone to sagging and deformation after long-term use.
[0038] In the embodiments of this application, such as Figure 4 , Figure 5 and Figure 6 As shown, the blind end of the angle limiting groove is provided with a dynamic tilting stop surface 525. All dynamic tilting stop surfaces 525 in the same group have the same tilting direction. The end of the limiting rib 21 is provided with a static tilting stop surface 211 that can fit with the dynamic tilting stop surface 525. The blind end of the angle limiting groove is provided with a dynamic tilting stop surface 525, and the limiting rib 21 is provided with a static tilting stop surface 211. The static tilting stop surface 211 can not only play a guiding role when the limiting rib 21 slides into the angle limiting groove, but also increase the local wall thickness of the angle limiting groove by setting the dynamic tilting stop surface 525. The cooperation between the dynamic tilting stop surface 525 and the static tilting stop surface 211 prevents the fixed bracket 6 from rotating in the tilted state.
[0039] In the embodiments of this application, such as Figure 4 , Figure 5 and Figure 7 As shown, the inner wall of the connecting sleeve 2 is provided with two limiting ribs 21 that are offset by 180 degrees in the circumferential direction, and the static inclined stop surfaces 211 on the two limiting ribs 21 are symmetrically arranged.
[0040] Specifically, two sets of angle limiting grooves are provided on the outer perimeter of the second rod body 52, and the two sets of angle limiting grooves are symmetrically arranged along the axis center plane. The tilting directions of the dynamic tilting stop surfaces 525 provided on the two sets of angle limiting grooves are opposite. With this structure, no matter which direction the fixed bracket 6 tilts, at least one dynamic tilting stop surface 525 will abut against the corresponding static tilting stop surface 211, thereby stably maintaining the tilting posture of the fixed bracket 6. Moreover, since the angle limiting grooves are locally processed, the processing difficulty of the stop structure is reduced, and the production cost is reduced.
[0041] In the embodiments of this application, the radial cross-section of the limiting rib 21 is large at the root and small at the top, and the top of the limiting rib 21 is an arc surface. This structure maximizes the strength of the limiting rib 21 and the angle limiting groove, making the application more reliable and stable.
[0042] In the embodiments of this application, such as Figure 6 and Figure 7 As shown, the angle limiting groove assembly includes three angle limiting grooves, with the longest being the one located in the middle position. When the limiting rib 21 engages with the angle limiting groove in the middle position, it ensures that the fixing bracket 6 is in a horizontal position. The longest angle limiting groove in the middle position provides wall thickness on both sides, increasing its strength and ensuring sufficient strength and stability for the fixing bracket 6 in a horizontal position.
[0043] like Figure 7 As shown, the three angle limiting grooves located in the same angle limiting groove group are the first angle limiting groove 521, the second angle limiting groove 522, and the third angle limiting groove 523. The second angle limiting groove 522 is the angle limiting groove located in the middle position. When the limiting rib 21 cooperates with the second angle limiting groove 522, the fixed bracket 6 is in a horizontal posture. When the limiting rib 21 cooperates with the first angle limiting groove 521 or the third angle limiting groove 523, the fixed bracket 6 is in an inclined posture, and at least one movable inclined stop surface 525 abuts against the corresponding static inclined stop surface 211, thereby stably maintaining the inclined posture of the fixed bracket 6, so that the adjustable placement plate 7 connected to the fixed bracket 6 can maintain a stable inclined posture.
[0044] When the rotating mechanism is in use, the second rod body 52 is separated from the connecting sleeve 2 by pulling the connecting rod 5. The connecting rod 5 is in the first position. After the connecting rod 5 rotates a certain angle, it is released. The compression spring 3 drives the connecting rod 5 to slide into the connecting sleeve 2. The limiting rib 21 slides into the corresponding angle limiting groove until the connecting rod 5 can no longer slide in. At this point, the connecting rod 5 is in the second position and is locked. The connecting rod 5 cannot rotate, and therefore cannot drive the fixed bracket 6 to rotate automatically. The adjustment is then complete.
[0045] Given that this application has already disclosed a technical solution for a rotating mechanism, this application further discloses a technical solution:
[0046] like Figure 8 , Figure 9 , Figure 10 and Figure 11The shoe holder shown includes a rotating mechanism as described above, comprising a hanging bracket 1 connected to a connecting sleeve 2, a fixed bracket 6 connected to a connecting rod 5, and an adjustable placement plate 7 disposed on the fixed bracket 6. The fixed bracket 6 includes a guide rod 61 extending along the length direction and a support plate 62 connected to the side of the guide rod 61. The adjustable placement plate 7 includes a pair of symmetrically arranged sub-placement plates 71. Each sub-placement plate 71 includes a first plate body 711 slidably connected to the guide rod 61 and a second plate body 712 slidably disposed on the first plate body 711 along the width direction. The second plate body 712 slidably engages with a guide groove 621 located on the support plate 62. In use, when the pair of sub-placement plates 71 move away from or closer to each other, the second plate body 712 moves away from or closer to the first plate body 711 to achieve size adjustment of the placement plate, so as to meet the needs of placing and displaying items of different sizes.
[0047] Specifically, the hanging bracket 1 is used to mount and fix the display rack, wall, or other structures for mounting the bracket 6. The adjustable placement plate 7, as its name suggests, is used to place display items. The first plate 711 has a sliding sleeve 7111 on its side connected to the guide rod 61. The second plate 712 has a linkage rod 7121 slidably connected to the first plate 711 on its side near the first plate 711. The linkage rod 7121 is perpendicular to the length direction of the guide rod 61. The cross-section of the linkage rod 7121 is I-shaped or dovetail-shaped. The first plate 711 has a long groove with an I-shaped or dovetail-shaped cross-section that slidably engages with the linkage rod 7121. The support plate 62 is located below the adjustable placement plate 7. The top surface of the support plate 62 has two guide grooves 621 distributed in a V-shape. The guide grooves 621 extend along the length direction of the guide rod 61. The second plate 712 has a sliding engagement with the guide grooves 621. When adjusting the length of the adjustable placement plate 7 by moving the slider and the pair of sub-placement plates 71 away from or closer to each other, the linkage rod 7121 causes the second plate 712 and the first plate 711 to move simultaneously. During the movement of the sub-placement plate 71, the guide groove 621 guides the second plate 712 away from or closer to the first plate 711, thereby adjusting the width of the adjustable placement plate 7. After adjustment, the corresponding locking mechanism locks the adjustable placement plate 7. For example, a screw threaded to the support plate 62 is used to press against the sub-placement plate 71, or an elastic pressure plate mounted on the fixed bracket 6 is used to press against the sub-placement plate 71. The guide groove 621 can also be a combination of a slanted groove and a straight groove. When the slider of the second plate 712 is engaged with the straight groove, only the length of the placement plate is adjusted, while the width remains unchanged. When the slider of the second plate 712 is engaged with the slanted groove, both the length and width of the placement plate are adjusted simultaneously.
[0048] In a preferred embodiment of this application, the adjustable placement plate 7 further includes two connecting rods 713 of equal length. One end of each connecting rod 713 is hinged to a corresponding first plate 711, and the other end of each connecting rod 713 is movably hinged to a connecting shaft 82 of the adjusting mechanism 8. A nut 83 of the adjusting mechanism 8 is connected to the upper end of the connecting shaft 82, thus limiting the two connecting rods 713 to the connecting shaft 82. An end plate 81 connected to the lower end of the connecting shaft 82 has an elastic locking mechanism that acts on a support plate 62. By pushing the connecting shaft 82 to move, the two connecting rods 713 swing simultaneously, thereby enabling a pair of placement plates 71 to move synchronously along the guide rod 61, simplifying the adjustment process. The position locking of the pair of placement plates 71 is achieved by locking the connecting shaft 82 using the elastic locking mechanism.
[0049] The elastic locking mechanism can be a locking rod driven by elastic force, which locks the position of the connecting shaft 82 by inserting the locking rod into the support plate 62.
[0050] In a preferred embodiment of this application, the end plate 81 is slidably connected to the limiting frame 63 located on the lower surface of the support plate 62. The support plate 62 has a slot 622 through which the connecting shaft 82 passes. The slot 622 is perpendicular to the guide rod 61 and is located between a pair of placement plates 71. A spring 84 and a locking ball 85 are provided in a blind hole on the side of the end plate 81. The locking ball 85 is held against the limiting frame 63 by the action of the spring 84. The limiting frame 63 has multiple slots that can cooperate with the locking ball 85. By moving the end plate 81, the connecting shaft 82 is moved, thereby moving the pair of placement plates 71. At the same time, the length and width of the adjustable placement plates 7 are adjusted. After adjustment, the position is locked by connecting the locking ball 85 with the corresponding slot.
[0051] In the embodiments of this application, the length of the sliding sleeve 7111 can be the same as the length of the first plate 711. When the length of the adjustable placement plate 7 is at its shortest, the end of the guide rod 61 can just protrude from the sliding sleeve 7111. When the length of the adjustable placement plate 7 increases, the sliding sleeve 7111 can hide the end of the guide rod 61. The lengthening of the sliding sleeve 7111 improves the connection reliability of the adjustable placement plate 7 and also makes the shoe rack more aesthetically pleasing. The top surface of the adjustable placement plate 7 has anti-slip protrusions, and both ends of the adjustable placement plate 7 have anti-slip end blocks.
[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
