Abstract
A Nutation-adjusting spanner is to solve the existing problems of pipe connection piece and the dismounting difficulty of water meter. The characteristic lies in: a driving head(1) and a handle(2) are articulated, the driving head(1) connects the handle (2) with pins (3). The adjustable nutation spanner applies to the water meter which is equipped under the pipe back at the barrier position and closing the very wall to make the water meter to be changed successfully with less labor and time to get high working efficiency.
Description
Technical field:
The utility model relates to the employed a kind of instrument of oil field pipe field dismounting connector, belongs to a kind of adjustable preliminary operation head spanner.
Background technology:
In resident's water supply field, because pipeline wears out or gets rusty and will dismantle conduit coupling sometimes, as short circuit, loose joint, the four directions that is threaded such as valve, hexahedron and water meter, the installation site of some user's water meter or connector is very unreasonable, stopped or the position very close by upper and lower conduit apart from metope, general instrument can't arrive place under repair herein, bring very large difficulty for maintenance and replacing, also can accidentally injure finger in the time of accidentally, dismounting is not in most cases got off, influence the replacing of water meter, the resident can not water, makes troubles for resident's life.
Summary of the invention:
In order to solve the deficiency that exists in the background technology, the utility model provides a kind of adjustable preliminary operation head spanner, this is adjustable, and preliminary operation head spanner is applicable to that the back side of water meter installation site under water pipe is hindered position and the position dismounting very near apart from wall, water meter can be changed smoothly, the time time saving and energy saving, high efficiency.
Technical solution adopted in the utility model is: this is adjustable, and preliminary operation head spanner comprises driving end, handle, and driving end and handle are hinged, and driving end is connected by pin with handle.
It is oral that the interior sidewall of the above-mentioned spanner draught animals is fixed a Flexible spanner by screw; Driving end is the survivor of a murder attempt; Handle has tenon, has on the driving end and the tenon corresponding groove, and tenon places in the groove and by pin and connects.
The beneficial effects of the utility model are: the handle of this is adjustable preliminary operation head spanner and driving end are hinged promptly to flexibly connect, in use hindered position and the position very near apart from wall for the back side of water meter installation site under water pipe, can both it is smooth, water meter can be dismantled smoothly, the time time saving and energy saving, high efficiency, alleviate employee's working strength, made things convenient for urbanite water consumption simultaneously.
Description of drawings:
Fig. 1 is a partial sectional view of the present utility model;
Fig. 2 is the partial sectional view of the utility model embodiment 2.
1-handle among the figure, the 2-driving end, the 3-pin, 4-opens wheel, and the 5-Flexible spanner is oral, 6-screw, 7-tenon, 8-groove.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in fig. 1, this is adjustable, and preliminary operation head spanner comprises driving end 1, handle 2, driving end 1 is hinged with handle 2, driving end 1 is connected by pin 3 with handle 2, to fix a Flexible spanner by screw 6 oral 5 for a sidewall in 1 mouthful of the driving end, unloads Flexible spanner oral 5 for the rotatable screw 6 of large-sized connector.
As shown in Figure 2, driving end 1 is the survivor of a murder attempt, can adjust the size of spanner mouth by rotarily opening wheel 4, and the connector for size dimension can both be suitable for like this.
In a utility model, for this spanner in use pin be difficult for being fractureed, handle 2 has tenon 7, has on the driving end 1 and tenon 7 corresponding groove 8, tenon 7 places in the groove 8 and by pin 3 and connects.
Because the driving end 1 of this adjustable preliminary operation head spanner can be spent to the angular transformation between 150 degree 20, in actual use, hindered position and the position not easy-operating place very near for the back side of water meter installation site under water pipe apart from wall, use the driving end of spanner at ordinary times to arrive, work can't be carried out, use this adjustable preliminary operation head spanner, these positions of the driving end of this spanner can both reach, water meter and connector are dismantled smoothly, the time time saving and energy saving, high efficiency, alleviate employee's working strength, made things convenient for urbanite water consumption simultaneously.This is adjustable water meter that preliminary operation head spanner dismantled, the one side distance apart from downcomer of water meter narrows down to more than 1 millimeter, only needs 33 millimeters the scope can apart from metope.
