Description
Technical field
The present invention relates to a kind of bottle gouard moved by hands, be specifically related to a kind of resilience handle of Lever Blocks.
Background technology
Lever Blocks is that a use is simple, Manual hoisting instrument easy to carry, pull handle by manpower manual to carry out hoisting heavy by the straight line tractive force that lever principle obtains and load matches, the handle of existing Lever Blocks is all back and forth pulling manually by cw and conter clockwise, realize lifting by crane and transfer weight, in order to improve the using method of Lever Blocks, people also carried out improvement to its handle, as: application number is: the Chinese patent " a kind of handle arrangement of Lever Blocks " of 2014100057512, but such improvement just changes into artificial push pull maneuver up and down by originally artificial to handle cw and pulling back and forth of conter clockwise, and do not alleviate the fatigue manually back and forth pulled.
Summary of the invention
Can only pulling back and forth or deficiency that up and down drawing handle could lift by crane and transfer weight by manpower in order to overcome existing Lever Blocks, the present invention proposes a kind of handle of Lever Blocks, that is: a kind of resilience handle of Lever Blocks.
Technical scheme of the present invention is as follows: a kind of resilience handle of Lever Blocks, it comprises Lever Blocks body, resilience handle and extension spring, resilience handle is wherein on the handle both sides of Lever Blocks or top or on the line of centers of its length direction, is fixed with installation ring or post or hole, in the lower end of resilience handle, sheath is housed, sheath has through hole; One end of extension spring is fixed on installation ring on resilience handle or post or hole, the other end of extension spring is fixed on the Lever Blocks body of resilience handle side or on the case of Lever Blocks body, or be arranged on the Lever Blocks body of resilience handle side or on the case of Lever Blocks body by support (post), make the angle of resilience handle between the line of centers and the hook of Lever Blocks body of length direction be not more than 90 degree, and the through hole internal fixtion on sheath have antifriction-bearing box.
Function of the present invention is achieved in that common Lever Blocks is after suspension, and its handle is because being sagging by the Action of Gravity Field of self, that is: common Lever Blocks is after suspension, and the angle of its handle between the line of centers and hook of length direction is 180 degree; The resilience handle of Lever Blocks of the present invention is after suspension, and its resilience handle upwarps because of the effect being subject to extension spring, that is: the resilience handle of Lever Blocks is after suspension, and the angle of its resilience handle between the line of centers and hook of length direction is less than 90 degree.
Because common Lever Blocks is after suspension, the angle of its handle between the line of centers and hook of length direction is 180 degree, so, common Lever Blocks back and forth must pull handle by artificial cw and conter clockwise when lifting by crane and transferring weight, just can complete Lever Blocks lifting and transfer the operation of weight; And the angle of the resilience handle of Lever Blocks of the present invention between the line of centers and hook of length direction is not more than 90 degree, so, with resilience handle Lever Blocks lifting and handle need only be pulled by artificial cw or conter clockwise when transferring weight, the operation of lifting by crane and transferring weight can be completed, this, simplifies manual operation process, which reduce the fatigue manually back and forth pulled.
In addition, when the suspension height of common Lever Blocks exceedes human height, the situation that manually cannot operate will be caused; And the resilience handle of Lever Blocks of the present invention, a rope or metal drag hook can be installed in the through hole on resilience handle cover, manually need only pull down running rope rope or metal drag hook can complete the lifting of weight and put down operation; Therefore, the resilience handle of Lever Blocks of the present invention not only alleviates artificial fatigue but also expands the field of application of Lever Blocks.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention, be also resilience handle after suspension, be in the schematic diagram of hoisting heavy state.
Fig. 2 be Fig. 1 resilience handle when hoisting heavy, the view after pulling under resilience handle cw.
Fig. 3 is the view of resilience handle when transferring weight.
Fig. 4 be Fig. 3 resilience handle when transferring weight, the view after pulling under resilience handle conter clockwise.
Fig. 5 is another kind of structural representation of the present invention, that is: resilience handle both sides are fixed with the structural representation of installation ring, and wherein: 6 for being fixed on the pillar on case, 7 is extension spring, 8 for being fixed on the installation ring of resilience handle both sides, and handle is in the state of hoisting heavy.
Fig. 6 is that in Fig. 5, resilience handle is in view when transferring weight.
The common Lever Blocks of Fig. 7 after suspension, the view of handle.
Fig. 8 is another kind of structural representation of the present invention, that is: resilience handle is fixed with the structural representation of erection column on the line of centers of its length direction, wherein: 6 for being fixed on the pillar on Lever Blocks body, 7 is extension spring, 8 for being fixed on the erection column on the line of centers in resilience decreased food direction, and handle is in the state of hoisting heavy.
Detailed description of the invention
See the resilience handle (to be fixed with installation ring at handle tip) of Fig. 1 a kind of Lever Blocks of the present invention, it comprises Lever Blocks body 9, resilience handle 4 and extension spring 7, resilience handle 4 is wherein fixed with installation ring 8 on the top of the handle 4 of Lever Blocks, sheath 3 is equipped with in the lower end of resilience handle 4, sheath 3 has through hole 2, has antifriction-bearing box 2 at through hole 2 internal fixtion; Resilience handle 4 there is commutation shifting block 5; Lever Blocks body 9 is fixed with pillar 6, one end of extension spring 7 is fixed on the installation ring 8 on resilience handle 4 top, the other end of extension spring 7 is fixed on the pillar 6 of the Lever Blocks body 9 of resilience handle 4 side, makes the included angle A of resilience handle 4 between the line of centers and the hook 1 of Lever Blocks body 9 of length direction be not more than 90 degree.
Function of the present invention is achieved in that common Lever Blocks is after suspension, its handle is because by the Action of Gravity Field of self being sagging (referring to: Fig. 7), so, back and forth must pull handle by artificial cw and conter clockwise when lifting by crane and transfer weight with common Lever Blocks, just can complete the lifting of weight and transfer operation, and the resilience handle 4 of Lever Blocks of the present invention is after Lever Blocks body 9 hangs, its resilience handle 4 upwarps because of the effect being subject to extension spring 7, that is: the resilience handle 4 of Lever Blocks is after Lever Blocks body 9 hangs, the included angle A of its resilience handle 4 between the line of centers and hook 1 of length direction is less than 90 degree (referring to: Fig. 1), so, when the Lever Blocks body 9 with resilience handle 4 is at hoisting heavy, resilience handle 4 deasil need only be pulled Fig. 2 position (referring to: Fig. 2) from the position of Fig. 1, then, unclamp resilience handle 4, resilience handle 4 will automatically revert to the initial position of Fig. 1 under the effect of extension spring 7, so cw pulls resilience handle 4 repeatedly, the lifting operation of weight can be completed, therefore, with the Lever Blocks body 9 of resilience handle 4 when hoisting heavy, resilience handle 4 need only be pulled by artificial cw, and manually need not carry out conter clockwise reset to resilience handle 4, the operation of hoisting heavy can be completed, this, simplifies manual operation process, which reduce the fatigue manually back and forth pulled, situation (referring to: Fig. 3 and Fig. 4) when transferring weight with resilience handle 4 is similar with it, repeats no more herein.
