Abstract

An assembly and disassembly device for a porcelain insulator base screw relates to a screw assembly and disassembly device. An internally hexagonal recess (7) is arranged in the middle of the upper end face of a chuck (8), a through hole (14) penetrating through a sector gear (10) is arranged at the inner bottom of the internally hexagonal recess, the lower end of the chuck movably penetrates through the upper surface of an angular plate (9) and is fixedly connected with the sector gear, the sector gear is meshed with another sector gear (11), a connecting rod (12) penetrates through a side plate of the angular plate behind the other sector gear, a stirring handle (6) is arranged on the outer side of the connecting rod, the outer end of the stirring handle is connected with an end of a handle (5), and a side handle (13) is arranged at one end of the angular plate. The chuck is clamped on a nut on the lower portion of a supporting screw, the lower end of the supporting screw is placed in the through hole, and the bore diameter of the through hole is larger than the diameter of the lower portion of the supporting screw. The nut can be easily detached by tightly griping the side handle with one hand while screwing up the handle with the other hand.

Description

The base screw of china bottle handler

[technical field]

The utility model relates to a kind of screw provision for disengagement, especially relates to a kind of base screw of china bottle handler.

[background technology]

Known; Existing electric wire need carry out transition by angle bar, porcelain vase usually when registering one's residence installation, can find out that in conjunction with accompanying drawing 1 said structure the studdle (2) of porcelain vase (1) bottom is fixed on the angle bar (4) through two nuts (3); Because the gap is less between the interior angle of studdle (2) lower end and angle bar (4); So it is all comparatively difficult to dismantle nut (3), especially after death has no idea basically to dismantle at nut (3) rust, and power construction is caused very big difficulty at every turn.

[summary of the invention]

In order to overcome the deficiency in the background technology; The utility model discloses a kind of base screw of china bottle handler; Said base screw of china bottle handler is connected to through dop on the nut of studdle bottom, and perforation is put in the lower end of studdle, just can easily unload lower nut through handle then.

For realizing the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of base screw of china bottle handler; Comprise dop, dihedral plate, sector gear, another sector gear, handle and side handle, the middle part, upper surface of dop is provided with interior six sides depression, and the bottom in interior six sides depression is provided with the perforation that connects sector gear; The upper side that the dihedral plate is passed in the lower end activity of dop is fixedly connected with sector gear; Said sector gear and another sector gear are meshing, and the side plate of dihedral plate is passed by connecting rod in the rear portion of another sector gear, and one side is provided with and stirs handle in the outer end of connecting rod; An outer end of stirring connects an end of handle, is provided with side handle at an end of dihedral plate.

Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:

The said base screw of china bottle handler of the utility model is connected on the nut of studdle bottom through dop; Perforation is put in the lower end of studdle; The aperture of perforation is greater than the bottom of studdle; Then hold tight side handle for one, the another hand just can easily unload lower nut through screwing handle; The utility model is simple in structure, for the dismounting effect highly significant of rust nut cap.

[description of drawings]

Fig. 1 is the syndeton sketch map of existing base screw of china bottle;

Fig. 2 is the structural representation of the utility model;

Fig. 3 is that the A of Fig. 2 is to view;

Among the figure: 1, porcelain vase; 2, studdle; 3, nut; 4, angle bar; 5, handle; 6, stir handle; 7, interior six sides depression; 8, dop; 9, dihedral plate; 10, sector gear; 11, another sector gear; 12, connecting rod; 13, side handle; 14, perforation.

[specific embodiment]

Can explain in more detail that through following embodiment the utility model, the utility model are not limited to following embodiment;

In conjunction with accompanying

drawing

2 or 3 described base screw of china bottle handlers; Comprise dop 8, dihedral plate 9, sector gear 10, another sector gear 11, handle 5 and side handle 13; The middle part, upper surface of dop 8 is provided with interior six sides depression 7; Bottom in interior six sides depression 7 is provided with the perforation 14 that connects sector gear 10, and the upper side that dihedral plate 9 is passed in the lower end activity of dop 8 is fixedly connected with sector gear 10, and said sector gear 10 is meshing with another sector gear 11; The side plate of dihedral plate 9 is passed at the rear portion of another sector gear 11 by connecting rod 12; A side is provided with and stirs 6 in the outer end of connecting rod 12, stirs an end that connects 6 outer end on handle 5, is provided with side handle 13 at an end of dihedral plate 9.

Implement the said base screw of china bottle handler of the utility model, the structure in conjunction with accompanying

drawing

1,2 or 3 provides at first is connected on the nut 3 of studdle 2 bottoms through dop 8; Perforation 14 is put in the lower end of studdle 2; Because perforation 14 aperture is greater than the bottom of studdle 2, thus bore a hole 14 can not influence nut 3 dismounting, hold tight side handle 13 by one; The another hand just can easily unload lower nut 3 through screwing handle 5.

The utility model does not detail part and is prior art.

Claims

1. base screw of china bottle handler; Comprise dop (8), dihedral plate (9), sector gear (10), another sector gear (11), handle (5) and side handle (13); It is characterized in that: the middle part, upper surface of dop (8) is provided with interior six sides depressions (7); Bottom in interior six sides depressions (7) is provided with the perforation (14) that connects sector gear (10), and the upper side that dihedral plate (9) is passed in the lower end activity of dop (8) is fixedly connected with sector gear (10), and said sector gear (10) is meshing with another sector gear (11); The side plate of dihedral plate (9) is passed at the rear portion of another sector gear (11) by connecting rod (12); A side is provided with and stirs (6) in the outer end of connecting rod (12), stirs an end that connects the outer end of (6) on handle (5), is provided with side handle (13) at an end of dihedral plate (9).
