Problems solved by technology
The pulley block is also a kind of lever, but the pulley block in the prior art cannot move with the load and work continuously, because it cannot make the load close to the fulcrum better, so it is relatively not labor-saving enough
For example, the "a lever gear rotation prying technology CN105065602A" disclosed in the prior art is actually the same lever as a whole, the fulcrum does not move, the fulcrum does not move, and it is equivalent to the same lever with the same fulcrum. It can be seen that the structure not good

Embodiment Construction
[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] Such as Figure 1-7 As shown, a kind of pulley block structure of the present invention that can work continuously to make the load close to the fulcrum as far as possible includes a wheel set 3 with an inner wheel 1 and an outer wheel 2, and the wheel set 3 is provided with a connecting shaft 4, and the wheel set The bottom of 3 is provided with track 5, to constitute the fulcrum of wheel lever, track is connected with a base 24, also includes:
[0029] The first support 6; the first support 6 is provided with a central axis 7 and a plurality of telescopic rods 8;
[0030] The se...

The invention relates to the field of pulley blocks, and specifically discloses a pulley block structure capable of continuous work to allow the load to be as close as possible to the fulcrum, including a wheel set with an inner wheel and an outer wheel. There is a track below to form the fulcrum of the wheel body lever. The track is connected to a base, and it is characterized in that it also includes: a first support; a second support; a rotating branch sleeve; a third support; A rotating bracket is connected to the third support, and a second bull's-eye ball pulley is arranged on the rotating bracket, and the second bull's-eye ball pulley faces the inner wheel surface of the wheel set for the third support. Rotate synchronously with the central axis. The pulley block structure of the present invention can work continuously, and can make the load close to the fulcrum to the greatest extent, so it saves labor, and its useful work can be greatly improved, thereby helping to save energy.
Description
technical field [0001] The invention relates to the field of pulley blocks, in particular to a pulley block structure capable of continuous work to allow loads to approach the fulcrum to the maximum. Background technique [0002] In daily life, the bar lever just puts the load on the fulcrum, but in reality the load does not move at all. The pulley block is also a kind of lever, but the pulley block in the prior art cannot move with the load and work continuously, because it cannot make the load close to the fulcrum better, so it is relatively labor-saving. For example, the "a lever gear rotation prying technology CN105065602A" disclosed in the prior art is actually the same lever as a whole, the fulcrum does not move, the fulcrum does not move, and it is equivalent to the same lever with the same fulcrum. It can be seen that the structure The effect is not good. Contents of the invention [0003] In order to overcome the above defects and deficiencies of the prior art, ...
