DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] As Figs. 1-3As shown, a kind of ball prism support, including support seat 1, recess 2 is opened in the surface inside above of support seat 1, the inner surface of recess 2 is equipped with soft scraping strip 3, the surface inside of support seat 1 is evenly distributed with the magnetism ball 4 rotationally arranged below recess 2, the bottom of support seat 1 is fixedly installed with magnetic attraction piece 5, the left and right side inner wall and inner side of support seat 1 are all provided with positioning mechanism 6, the middle groove inside of support seat 1 is placed with ball prism main body 7;The diameter of soft scraping strip 3 is matched with the diameter of recess 2, the inner circular surface of soft scraping strip 3 protrudes from the recess 2 and is located in the groove inside of support seat 1, and the inner circular surface of soft scraping strip 3 is set as the arc surface matched with the arc shape of the groove of support seat 1;One side of magnetism ball 4 protrudes in the groove inside of support seat 1, and the protruding distance of magnetism ball 4 is same with soft scraping strip 3, and magnetic attraction piece 5 keeps the same arc surface with the bottom of support seat 1.

[0023] By adopting the above technical scheme, when ball prism main body 7 is placed into the groove inside of support seat 1, it is preferentially attached to magnetism ball 4, and the protruding distance of magnetism ball 4 itself can prevent ball prism main body 7 from contacting the surface of the groove, thereby reducing the friction contact surface;

[0024] When ball prism main body 7 rotates, magnetism ball 4 also rotates and is attached, so as to change sliding friction into rolling friction, which can greatly reduce the friction force and friction contact surface between the surface of ball prism main body 7 and support seat 1, and the rotation is more labor-saving, and it can also prevent the friction and damage of ball prism main body 7 from occurring after multiple rotations;

[0025] Due to magnetism ball 4, magnetic attraction piece 5 cannot directly attach ball prism main body 7, but can only generate downward pulling force on ball prism main body 7 by magnetic force through a certain interval distance, so as to ensure that ball prism main body 7 can be stably installed in the groove of support seat 1;

[0026] Ball prism main body 7 can preferentially contact soft scraping strip 3 at the position on the upper side of the groove, and soft scraping strip 3 is attached to the surface of ball prism main body 7, so as to block and scrape dust when ball prism main body 7 rotates.

[0027] Soft scraping strip 3 can be directly taken out from recess 2 for disassembly, and when installed, it is only necessary to pinch soft scraping strip 3 and directly place it into recess 2, so as to embed and install it in recess 2 by using the elastic deformation force of soft scraping strip 3 itself.

[0028] Further, positioning mechanism 6 includes air cavity 601 formed in the left and right side inner walls of support seat 1, and piston 602 is slidably attached to the inner surface of air cavity 601;Positioning mechanism 6 further includes threaded hand lever 603 rotationally connected to the upper surface of piston 602, and the upper end of threaded hand lever 603 penetrates support seat 1 and is threadedly connected with the inner wall of support seat 1 at the penetrating position.

[0029] By adopting the above technical scheme, the threaded hand lever 603 rotates, and the piston 602 is driven to move in the air cavity 601 by screwing.

[0030] Further, the positioning mechanism 6 further comprises suction cups 605 fixedly installed on the inner sides of the left and right sides of the surface of the support base 1, and air channels 604 are fixedly connected to the opposite sides of the surfaces of the suction cups 605. The air channels 604 are arranged on the inner walls of the support base 1, and the ends of the air channels 604 away from the suction cups 605 are in communication with the air cavity 601.

[0031] By adopting the above technical scheme, in the process of moving the piston 602 upward, the gas in the air channels 604 is gradually extracted into the air cavity 601. Under the action of air pressure, the suction cups 605 become concave arc surfaces, which are greater than the contact surfaces of the ball prism body 7 and are in adsorption. Since the positions of the suction cups 605 are fixed, the position of the ball prism body 7 can also be effectively fixed after the ball prism body 7 is adsorbed by the suction cups 605.

[0032] Further, the suction cups 605 are in a planar state in a normal state, and the thickness of the suction cups 605 is the same as the protruding distance of the magnetic balls 4 and the soft scraping strips 3.

[0033] By adopting the above technical scheme, the thickness of the suction cups 605 does not affect the contact between the ball prism body 7 and the magnetic balls 4. In a normal state, the suction cups 605 are planar, and the surface of the ball prism body 7 is in single-point contact with the surface of the ball prism body 7, and the friction is very small. When it is not fixed, it does not affect the normal rotation of the ball prism body 7.

[0034] Further, the bottom plate 8 is fixedly installed on the lower surface of the support base 1, and mounting holes 9 are uniformly arranged on the surface of the bottom plate 8.

[0035] By adopting the above technical scheme, the bottom plate 8 is combined with the mounting surface through the mounting holes 9, and the fasteners are combined with the mounting surface, so that the support base 1 can be fixed as a whole.

[0036] Working principle: when the ball prism support is used, first, the ball prism body 7 is installed in the groove of the support base 1. The ball prism body 7 is preferentially adsorbed by the magnetic balls 4. The protruding distance of the magnetic balls 4 can prevent the ball prism body 7 from contacting the surface of the groove. The surface of the ball prism body 7 can be in contact with the soft scraping strip 3 on the upper side of the groove. At this time, the magnetic attraction block 5 cannot directly adsorb the ball prism body 7 due to the magnetic balls 4, but can generate a downward magnetic force on the ball prism body 7 through a certain interval distance, so as to ensure that the ball prism body 7 can be stably installed in the groove of the support base 1.

[0037] After installation, rotate the spherical prism body 7 to the appropriate angle. When the spherical prism body 7 rotates, the magnetic balls 4 will also be attracted to rotate, converting sliding friction into rolling friction, which can greatly reduce the friction and friction contact surface between the surface of the spherical prism body 7 and the support seat 1, making rotation more labor-saving. It can also prevent the spherical prism body 7 from being scratched by friction during multiple rotations. When the spherical prism body 7 rotates, the soft scraping strip 3 will adhere to the surface of the spherical prism body 7 and scrape, preventing dust from entering the groove and affecting the magnetic attraction effect of the magnetic balls 4;

[0038] After the spherical prism body 7 is adjusted to the appropriate angle, rotate the threaded hand lever 603 to drive the piston 602 to move upwards, which will suck the air on one side of the suction cup 605 into the air chamber 601 for storage. Under the action of air pressure, the suction cup 605 will become a concave curved surface state, which is larger than the contact surface of the spherical prism body 7 and will be attracted. The position of the suction cup 605 is fixed, that is, after the suction cup 605 attracts the spherical prism body 7, the position of the spherical prism body 7 can also be effectively fixed. This is the working principle of the spherical prism support.
