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
[0003] For example, the "a lever gear rotation prying technology CN 105065602 A" 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 fulcrum and the same lever. It can be seen that the The effect of the structure is not good

Embodiment Construction
[0030] 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.
[0031] like 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:
[0032] The first support 6; the first support 6 is provided with a central axis 7 and a plurality of telescopic rods 8;
[0033] The secon...

The invention relates to the field of pulley blocks, and particularly discloses a pulley block structure capable of continuous working to make the load as close as possible to a fulcrum. The pulley block structure comprises a wheel set provided with an inner wheel and an outer wheel, wherein a connecting rotary shaft is arranged in the wheel set, a track is arranged below the wheel set to form thefulcrum of a wheel body lever, and the track is connected with a base; and the pulley block structure is characterized in that the pulley block structure further comprises a first support, a second support, a rotary branch sleeve pipe and third support; a rotating bracket is connected to the third support, a second bull eye ball pulley block is arranged on the rotating bracket, and the second bull eye ball pulley block faces the surface of the inner wheel of the wheel set and is used for achieving the synchronous rotation of the third support and a central shaft. According to the pulley blockstructure, continuous working can be achieved, the load can be as close as possible to the fulcrum, thus more labor is saved, the useful work done by the pulley block structure can be greatly improved, and thus the energy is advantageously saved.
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. [0003] For example, the "a lever gear rotation prying technology CN 105065602 A" 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 fulcrum and the same lever. It can be seen that the The effect of the structure is not good. Contents of the invention [0004] In order to overcome the above defects and deficiencies...
