Description

Technical Field

[0001] The utility model relates to the technical field of rotating racks, in particular to a rotating fixing device with stable rotation. Background Art

[0002] Bookshelves are a type of furniture used to place and store books, documents, decorations and other items. They are also one of the essential infrastructures in places such as homes or offices. Their main functions are to store, display, protect books and decorate the interior environment.

[0003] Since traditional bookshelves occupy a large area, they give people a full sense of oppression when filled with books. At present, in the process of home decoration, traditional bookshelves have been gradually replaced by new revolving bookshelves, which occupy a small area, save space well, and have a stronger aesthetic sense of craftsmanship. During the installation of the revolving bookshelf, a more common installation method is to rotate the bookshelf between the ground and the roof of the house, and set a bearing seat and bearings at the connection position between the bookshelf and the ground, and at the connection position between the bookshelf and the roof to assist in the rotation of the bookshelf. However, in actual application, since many books or other decorations will be stored on the bookshelf, the overall weight of the bookshelf will be very heavy, so the bearing seat will be under very great pressure. During long-term use, if traditional bearings are used, the bearing seat or bearing is prone to damage or deformation. Once this happens, the rotation of the bookshelf will be affected, the service life will be reduced, and there are also certain safety hazards. Utility Model Content

[0037] Specific implementation plan: see Figure 1-Figure 8 The utility model is a rotationally stable rotating fixing device, comprising a load-bearing component 1 and an upper connecting component 2 arranged in an upper and lower interval, wherein the load-bearing component 1 is installed on the ground, the upper connecting component 2 is installed on the top surface, and a storage rack 3 is provided between the load-bearing component 1 and the upper connecting component 2. The load-bearing component 1 includes:

[0038] The base 11 is fixed on the ground and has a first placement slot 111 built therein;

[0039] The first seat 13 is covered on the base 11, and the first seat 13 is provided with a first slot 131, and the first slot 131 and the first placement groove 111 cooperate to form a mounting position for a single first ball 12 to be matched and placed;

[0040] A first connecting structure is provided between the first seat 13 and the storage rack 3;

[0041] The upper connection assembly 2 comprises:

[0042] The upper seat 22 is fixed on the top surface and has a second placement groove 221 built in;

[0043] The second seat 24 is covered under the upper seat 22, and the second seat 24 is provided with a second slot 241, and the second slot 241 and the second placement groove 221 cooperate to form a mounting position for a single second ball 23 to be matched and placed;

[0044] A second connecting structure is provided between the second seat 24 and the storage rack 3 .

[0045] As a preferred implementation of this embodiment, please refer to Figure 2 and Figure 4 It can be seen that the lower end of the first seat 13 is separated from the base 11, and the upper end of the second seat 24 is separated from the upper seat 22.

[0046] Here, when the first seat 13 is placed above the base 11, the lower end of the first seat 13 is not in contact with the base 11, thereby reducing the contact area between the first seat 13 and the base 11, making the rotation resistance smaller, which is equivalent to the first seat 13 rotating on the first ball 12 to a certain extent. The base 11 is provided to prevent the first seat 13 from shifting in position during rotation.

[0047] Then, when the second sleeve 24 is placed under the upper seat 22, the upper end of the second sleeve 24 is not in contact with the upper seat 22, thereby reducing the contact area between the second sleeve 24 and the upper seat 22, making the rotation resistance smaller, which is equivalent to the second sleeve 24 rotating on the second ball 23 to a certain extent. The upper seat 22 is provided to prevent the second sleeve 24 from shifting in position during rotation.

[0048] In addition, in order to increase the overall structural strength, in the present embodiment, the load-bearing component 1 and the upper connecting component 2 are both made of high-strength stainless steel, including the first ball 12 and the second ball 23 which are also steel balls.

[0049] See also Figure 1 and Figure 2It can be seen that in this embodiment, the first connection structure is a first stud 14 fixed to the upper end of the first socket 13 , and the first stud 14 is screwed and fixed to the lower end of the storage rack 3 .

[0050] Then, the first connection structure further includes a first fixing plate 15 screwed on the first stud 14 , and the first fixing plate 15 is fixed to the lower end of the storage rack 3 by a plurality of screws.

[0051] See also Figure 3 It can be seen that the first fixing plate 15 is provided with a plurality of first screw holes 151 , screws are installed at the first screw holes 151 , and the first fixing plate 15 cooperates with the first studs 14 to effectively strengthen the connection strength between the first seat 13 and the storage rack 3 .

[0052] Next, see Figure 4 and Figure 6 It can be seen that the second connection structure is a second stud 25 fixed to the lower end of the second sleeve 24 , and the second stud 25 is screwed and fixed to the upper end of the rack 3 .

[0053] Then, the second connection structure further includes a second fixing plate 26 screwed on the second stud 25 , and the second fixing plate 26 is fixed to the upper end of the storage rack 3 by a plurality of screws.

[0054] See also Figure 5 It can be seen that the second fixing plate 26 is provided with a plurality of third screw holes 261 , screws are installed at the third screw holes 261 , and the second fixing plate 26 cooperates with the third studs to effectively strengthen the connection strength between the first seat 13 and the storage rack 3 .

[0055] See also Figure 1 and Figure 8 It can be seen that the lower end of the base 11 is provided with a screw hole for the expansion screw 4 to be screwed and fixed, and the expansion screw 4 is fixed on the ground.

[0056] For more details, see Figure 6 and Figure 8 It can be seen that an upper connecting plate 21 is fixed to the upper end of the upper seat 22 , and a plurality of second screw holes 211 are provided on the upper connecting plate 21 . The upper connecting plate 21 is fixed to the top surface by installing screws at the second screw holes 211 .

[0057] Please note that, see Figure 7 and Figure 8 Since the storage rack 3 is installed between the load-bearing component 1 and the upper connecting component 2, it can support the upper connecting component 2. Therefore, when the upper connecting plate 21 is fixed on the top surface, it will not be separated from the top surface.

[0058] In summary, the cooperation between the first ball 12 on the load-bearing component 1 and the second ball 23 on the upper component 2 can make the rotation of the storage rack 3 very stable. After actual testing, a single ball is used to replace the bearing, which has a stronger pressure-bearing capacity, will not deform or damage, and has a long service life.

[0059] The above description of a rotationally stable rotating fixing device of the present invention is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
