Detailed Description

In order to make the technical field personnel understand the utility model discloses the scheme, will combine the figure in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.

As shown in the figures 1-4, a novel simple tripod ball comprises a tripod ball body 10 which is arranged in a hollow manner, the inner wall of the tripod ball body 10 is in a sawtooth shape, so that the tripod ball can be perfectly matched with a half shaft, an oil storage cavity 19 is formed in the tripod ball body 10, two water injection holes are formed in one side end surface of the tripod ball body 10 and are communicated with the oil storage cavity 19, a sealing pin 15 is detachably arranged in each water injection hole, the sealing pin 15 is made of rubber, the lubricating oil can balance the air pressure in a cavity channel during injection through the arrangement of the two sealing pins 15, the difficulty of injecting the lubricating oil is reduced, and three ball ring assemblies are arranged on the outer peripheral side of the tripod ball body 10;

each ball ring component is fixed with the tripod body 10 through a guide pipe 18, one side end face of each guide pipe 18 far away from the central line of the tripod body 10 is fixedly connected with a ball ring 13, the peripheral side of each ball ring 13 is provided with a groove, an inner ball sleeve 12 is further sleeved on each ball ring 13, at least two roller pins 14 are arranged between the inner ball sleeve 12 and each ball ring 13, a guide pipe 18 and an oil outlet channel 17 are arranged in each ball ring 13, each guide pipe 18 extends to the central line direction of the tripod body 10 to penetrate through the connecting shaft 11 to be communicated with the oil storage cavity 19, each guide pipe 18 extends to the central line direction of the tripod body 10 to penetrate through the oil outlet channel 17, a convex block is arranged on the inner wall of one side of each guide pipe 18 far away from the tripod body 10, each oil outlet channel 17 is communicated with the groove, and the arrangement of the oil outlet channel 17 and the guide pipe 18, make lubricating oil can be stored in the tripod head, make it can reach lubricated effect many times, thereby the operating time of tripod head has been prolonged, it is equipped with sealing block 16 to slide in the pipe 18, a side end face that the tripod head 10 was kept away from to sealing block 16 and the pipe 18 inner wall within a definite time have linked firmly the spring, be equipped with the opening in the sealing block 16, open-ended opening direction is towards tripod head 10 central line direction, the through-hole has still been seted up in the sealing block 16, the through-hole communicates with sealing block 16's opening, the central line direction of through-hole is unanimous with the central line direction of oil drain 17, setting through sealing block 16, not only avoid lubricating oil to appear leaking, still can automatic lubricating oil that adds when tripod head rotates simultaneously, the efficiency of the maintenance of tripod head has been improved greatly.
