Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Example (b):
as shown in fig. 1, an abrasion-proof screw includes a rod body 1 and a screw rib 2 fixedly connected to an outer circumferential wall thereof.
As shown in fig. 5 and 6, a plurality of oil storage chambers 11 are formed in a rod body 1, the oil storage chambers 11 are uniformly arranged at intervals, adjacent oil storage chambers 11 are communicated with each other through holes 111, the aperture of each through hole 111 is smaller than one tenth of the aperture of each oil storage chamber 11, a plurality of through holes 3 which are communicated with the oil storage chambers 11 and are arranged in a one-to-one correspondence manner are formed in the peripheral wall of the rod body 1, as shown in fig. 2, one-way ball valves are fixedly connected in the through holes 3, the input ends of the one-way ball valves protrude out of the through holes 3, and when the input ends of the one-way ball valves are stressed and retracted, the one-way ball valves conduct the oil storage chambers 11 to the outside, when people use the screw and the structure in threaded connection with the screw to carry out transmission, the structure can be attached to the peripheral wall of the rod body 1 at, and the one-way ball valve is kept smooth, so that the lubricating oil in the oil storage cavity 11 can be thrown out through the one-way ball valve by the centrifugal force of the screw in the rotating process, the lubricating oil can be thrown between the screw and a structure in threaded connection with the screw for lubrication, the friction between the screw and the structure is reduced, and the screw rib 2 on the screw is prevented from being abraded.
As shown in fig. 6, the one end of the body of rod 1 has been seted up uncovered, open area is greater than the open area of oil storage chamber 11, can dismantle through bolt 8 in uncovered and be connected with baffle 7, when people need carry out lubricating oil interpolation work in the oil storage chamber 11, people can open baffle 7 through bolt 8, make open uncovered, then people can add lubricating oil in the oil storage chamber 11 towards, lubricating oil then can flow into next oil storage chamber 11 through-hole 111 in, until all oil storage chambers 11 in all set up sufficient lubricating oil.
As shown in fig. 3 and 4, the ball check valve includes a valve body 4 and a ball body 5, a receiving groove 41 is formed in the valve body 4, an upper end of the receiving groove 41 is communicated with a ball groove 42 penetrating the valve body 4, the aperture of the ball groove 42 is gradually increased from top to bottom, a cylinder 51 integrally formed with the ball body 5 is slidably connected in the receiving groove 41, an elastic member 6 is fixedly connected between the bottom surface of the receiving groove 41 and the bottom surface of the cylinder 51, an upwardly concave recess 44 is formed in the bottom surface of the valve body 4, the recess 44 is communicated with an outlet 45 communicated with the receiving groove 41 and the ball groove 42, the cylinder 51 and the ball body 5 shield the outlet 45, the ball body 5 protrudes out of the ball groove 42, a groove 43 communicated with the recess 44 is formed in the bottom surface of the valve body 4, the opening area of the groove 43 is larger than that of the recess 44, when, meanwhile, the cylinder 51 can compress the elastic element 6 which is a spring in the accommodating groove 41 under stress, after the ball body 5 and the cylinder 51 move downwards, the outlet 45 on the inner peripheral wall of the accommodating groove 41 and the ball groove 42 is not shielded by the ball body 5 or the cylinder 51 any more, so that the lubricating oil is exposed, the lubricating oil under the centrifugal force swinging action sequentially passes through the groove 43, the concave hole 44, the outlet 45, the accommodating groove 41 and the ball groove 42 to leave the one-way ball valve, so that the lubricating oil is thrown out, and when the ball body 5 does not bear acting force any more, the elastic element 6 releases elastic acting force.
When people need use this screw rod to carry out the driven, the screw rod can carry out the transmission with its threaded connection's structure, this structure is the nut for example, screw rod self takes place to rotate, and the structure receives spacing unable screw rod of following to take place to rotate, both take place along the guide motion of spiral shell arris 2 promptly, the structure can be along the length direction of screw rod displacement, and when the structure received spiral shell arris 2 guide, the structure can carry out relative rotation along the direction of spiral shell arris 2, thereby make the structure can contact the input of the one-way ball valve of the 1 periphery wall setting of the salient body of rod, can make the one-way ball valve keep unblocked, from this under the rotation of screw rod, lubricating oil throws out oil storage chamber 11 to the external world through centrifugal force, make lubricating oil be located between screw rod and the structure, take.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
