A rotation assist device

Abstract

The utility model discloses a rotation auxiliary device, which includes a base fixed on the ground, and an axle rod is provided at the upper end of the base; a fixing plate fixed to the lower end of the rotating member and abutted against the top of the base, and a through hole is provided on the fixing plate for the axle rod to pass through; an embedded block is sleeved on the axle rod, the embedded block is located above the fixing plate and embedded in the lower end of the rotating member, and a placement groove is provided at the lower end of the embedded block; a bearing is sleeved on the axle rod and matched and placed in the placement groove. The fixing plate and the embedded block of the utility model are fixedly connected, and a bearing is provided on the axle rod. Therefore, during the rotation of the rotating member, the fixing plate will rotate relative to the base. Since the base is kept abutting against the fixing plate, the design of the bearing can effectively reduce the friction resistance between the axle rod and the embedded block. Therefore, while ensuring the supporting effect on the rotating member, the rotation of the rotating member relative to the base can be very stable, and will not be affected by the slight sinking of the rotating member, so the service life is longer and the practicality is strong.

Description

Technical Field

[0001] The utility model relates to the technical field of rotating parts, in particular to a rotation auxiliary device. Background Art

[0002] In modern home decoration, in addition to doors that need to be rotated to open and close, many other decorative objects, such as screens and cabinets, also have a rotating function for ease of use. During use, the rotation function of the rotating part is generally achieved through a hinge. In addition, in order to increase the stability during the rotation process, a rotation auxiliary structure is generally installed directly below the corresponding position of the rotating shaft of the rotating part, that is, on the ground.

[0003] In the prior art, regarding the above-mentioned rotation auxiliary structure, a combination of a base and a mounting part is generally used, wherein the base is installed on the ground, the mounting part is installed on the rotating part, and a pin is provided between the base and the mounting part, and the rotation position is limited only by the pin. During frequent rotation, the position of the hinge is prone to loosening, which appears as the sinking of the rotating part. At this time, the rotation of the pin will be affected, which will in turn reduce the rotation smoothness of the rotating part, and it is easy to get stuck during rotation. In addition, after the rotating part is installed, in order to ensure the stability of the structure, it is generally not removed and adjusted, especially the position of the hinge. Therefore, when the rotation auxiliary structure is affected, it is difficult to adjust it. Utility Model Content

[0033] Specific implementation plan: see Figure 1-Figure 5 The utility model is a rotation assisting device, which is installed between the rotating member 6 and the ground and is used to assist the rotating member in rotating. The rotation assisting device includes:

[0034] A base 1 is fixed on the ground, and a shaft 12 arranged vertically is provided at the upper end of the base 1;

[0035] The fixed plate 2 is fixed to the lower end of the rotating member 6 and abuts against the top of the base 1. The fixed plate 2 is provided with a through hole 21 for the shaft 12 to pass through;

[0036] The embedded block 3 is sleeved on the shaft 12. The embedded block 3 is located above the fixed plate 2 and embedded in the lower end of the rotating member 6. The lower end of the embedded block 3 is provided with a placement groove 31;

[0037] The bearing 4 is sleeved on the shaft 12 and matchedly placed in the placement groove 31 .

[0038] See also Figure 4 It can be seen that in this embodiment, the bearing 4 includes an intermediate shaft connecting piece 42, and an upper connecting piece 43 and a lower connecting piece 41 respectively arranged at the upper and lower ends of the intermediate shaft connecting piece 42, and a plurality of rollers 421 spaced apart from each other are provided on the intermediate shaft connecting piece 42 along its own circumference, and the upper and lower ends of the rollers 421 are respectively abutted against the upper connecting piece 43 and the lower connecting piece 41.

[0039] Here, since the shaft 12 is fixed on the base 1, and the fixed plate 2 and the embedded block 3 are both fixed on the rotating member 6, the rotating member 6 will rotate relative to the base 1 during the opening or closing process of the rotating member 6, which is reflected in the relative rotation between the shaft 12 and the embedded block 3. In this process, the provision of the bearing 4 can effectively reduce the friction resistance between the shaft 12 and the embedded block 3.

[0040] In this embodiment, the working principle of the bearing 4 is as follows: when any one of the upper connecting piece 43, the lower connecting piece 41 and the intermediate shaft connecting piece 42 rotates relative to the shaft rod 12, it is manifested as a relative rotation between the upper connecting piece 43 and the intermediate shaft connecting piece 42, or a relative rotation between the lower connecting piece 41 and the intermediate shaft connecting piece 42. In this process, since the intermediate shaft connecting piece 42 has a plurality of rollers 421 arranged at intervals along its own circumference, and the upper and lower ends of the rollers 421 are respectively abutted against the upper connecting piece 43 and the lower connecting piece 41, the friction resistance of the upper connecting piece 43 relative to the intermediate shaft connecting piece 42 and the friction resistance of the lower connecting piece 41 relative to the intermediate shaft connecting piece 42 can be effectively reduced.

[0041] Then, a fixing structure is provided between the embedded block 3 and the fixing plate 2 .

[0042] In this example, see Figure 1 It can be seen that the fixing structure includes a second screw hole 23 provided on the fixing plate 2 and a third screw hole 32 provided on the embedded block 3. The second screw hole 23 and the third screw hole 32 are located correspondingly and are installed with fixing screws.

[0043] Next, in order to make the connection between the fixed plate 2 and the rotating member 6 more stable, in the present embodiment, the fixed plate 2 is in the shape of an elongated strip (which can increase the connection area between the fixed plate 2 and the rotating member 6), and a plurality of first screw holes 22 are provided on the fixed plate 2, and the fixed plate 2 is screwed and fixed to the lower end of the rotating member 6 through the first screw holes 22.

[0044] See also Figure 1 and Figure 2 , you can see that the base 1 includes:

[0045] A bottom plate 11 is fixed on the ground and is provided with a mounting opening 111;

[0046] The mounting block 14 is matched and placed in the mounting opening 111;

[0047] The abutment block 13 is fixed above the mounting block 14, and the abutment block 13 abuts against the lower end of the fixing plate 2;

[0048] The shaft rod 12 is fixed above the abutment block 13 .

[0049] More specifically, a slot hole 33 is provided at the upper end of the embedded block 3, and the slot hole 33 is located directly above the shaft rod 12. A cover plate 5 is detachably fixed above the embedded block 3. In the present embodiment, a plurality of fourth screw holes 51 are provided on the cover plate 5, and the positions of the fourth screw holes 51 and the third screw holes 32 correspond to each other.

[0050] Here, the slot hole 33 is provided to prevent the upper end of the shaft rod 12 from contacting an object, thereby reducing the friction resistance of the shaft rod 12 during rotation. The cover plate 5 is provided to seal the slot hole 33, and the overall aesthetics are better.

[0051] In this embodiment, the lower end of the rotating member 6 is provided with an embedding opening for the embedded block 3 to be embedded and installed.

[0052] See also Figure 5 , the installation process of the rotation assist device in this embodiment is described below:

[0053] First, determine the installation position of the base 1, and fix the bottom plate 11 of the base 1 to the ground with screws; then, place the mounting block 14 in the mounting opening 111 (note that in other embodiments, the mounting opening 111 and the mounting block 14 may not be provided, and the abutment block 13 may be directly fixed on the bottom plate 11); then, screw and fix the cover plate 5, the embedded block 3, and the fixed plate 2 together, and embed the embedded block 3 with the cover plate 5 in the embedded opening, and screw and fix the fixed plate 2 to the lower end of the rotating member 6; then, install the rotating member 6 from top to bottom, and make the shaft 12 pass through the through hole 21 and the bearing 4 in sequence, and enter the embedded block 3, at which time the abutment block 13 on the base 1 abuts against the lower end of the fixed plate 2; finally, install the hinge.
