Description
Technical Field
The invention belongs to the field of fastening devices, and particularly relates to a local universal fastening device.
Background
In the prior art, the universal ball is often used for connecting parts which need to be moved frequently, so that the universal ball is convenient to adjust and has a stable structure. However, the structure of the existing devices is complex.
There is a need for a stable, structurally simple, and inexpensive fastening device.
Disclosure of Invention
The invention aims to provide a fastening device which is stable, simple in structure, low in price and convenient to adjust.
The invention is realized by the following technical scheme:
a fastening device with a universal ball comprises a supporting rod, wherein the end part of the supporting rod is a universal ball head; comprising a ball shoe for connecting items to be fastened; the ball cover is also included; the ball tile is fixed between the universal ball head and the ball cover; the universal ball head, the ball tile and the ball cover are combined with each other in a spherical manner.
As a further improvement, the device also comprises a bolt; the universal ball head is provided with a ball upper screw hole, the ball cover is provided with a cover upper through hole, the ball tile is provided with a tile upper through hole, and the diameter of the tile upper through hole is larger than the diameter of the ball upper screw hole and the diameter of the cover upper through hole; the bolt passes through the screw hole on the ball, the through hole on the tile and the through hole on the cover.
As a further improvement, butter lubricant is added into the universal ball head, the ball tile and the ball cover.
The invention has the beneficial effects that:
1. the improved universal ball structure is used, so that the fixing is more stable; 2. the adjustment is very convenient; 3. simple structure, low cost and convenient manufacture.
Drawings
For ease of illustration, the invention is described in detail by the following specific examples and figures.
FIG. 1 is a perspective view of the connection of the present invention;
FIG. 2 is a plan view of the connection of the present invention;
FIG. 3 is a use reference diagram of the present invention;
the reference numerals for the figures are as follows:
1. a support rod; 11. a universal ball head; 2. a spherical tile; 3. a ball cover; 4. a bolt; 41. a screw hole is arranged on the ball; 42. covering the through hole; 43. a through hole is arranged on the tile; 5. and (6) sweeping the disc.
Detailed Description
For ease of illustration, the invention is described in detail by the following specific examples and figures.
As shown in fig. 1 and 2, the fastening device with the universal ball comprises a support rod 1, wherein a universal ball head 11 is arranged at the end part of the support rod 1; comprises a ball tile 2 for connecting fastened articles; also comprises a ball cover 3; the ball tile 2 is fixed between the universal ball head 11 and the ball cover 3; the universal ball head 11, the ball tile 2 and the ball cover 3 are combined with each other in a spherical way. The article that is fastened is connected on ball tile 2, loosens universal bulb 11, ball tile 2, spherical cover 3, can adjust the article that is fastened, because ball tile 2 is locked by the pressure on two sides, therefore its stability is superior to common universal ball after fixing.
The universal ball head 11 is provided with a ball upper screw hole 41, the ball cover 3 is provided with a cover upper through hole 42, the ball tile 2 is provided with a tile upper through hole 43, the bolt 4 passes through the ball upper screw hole 41, the tile upper through hole 43 and the cover upper through hole 42, and the diameter of the tile upper through hole 43 is larger than the diameters of the ball upper screw hole 41 and the cover upper through hole 42. Since the tile upper through hole 43 is large, the fastened article can be arbitrarily adjusted within the range of the tile upper through hole 43.
When the adjustable ball tile is used, the ball tile 2 can be adjusted by loosening the bolt 4, and the position of the ball tile 2 can be stabilized by fastening the bolt 4.
The following description will be made with reference to fig. 3 for a specific application of the present invention to a sweeper brush of a sweeper truck, and the present invention can be applied to other technical fields, and is not limited to the following manner. The sweeper is provided with a sweeper brush, the position of the sweeper brush is required to be stable during working, and the angle of inclination of the sweeper brush is required to be adjusted frequently. Therefore, the sweeper brush is arranged on the ball tile 2, so that the position of the sweeper brush can be conveniently adjusted, and the sweeping stability of the sweeper brush can be kept. When the inclination angle of the sweeping disc 5 needs to be adjusted, the inclination angle of the sweeping disc 5 can be adjusted by loosening the bolt 4, and the weight of the sweeping disc 5 is supported on the universal ball completely during adjustment; and because the combination force of the ball tile 2, the ball cover 3 and the universal ball head 11 is uniform, the adjusted inclination angle of the sweeping disc 5 cannot be displaced. Compared with other fixing modes, the inclination angle can be adjusted only by the tightness of one bolt 4, so that the adjustment convenience is kept, and the stability and the pressing force of the spherical tile 2 after the bolt 4 is screwed down are also kept.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
