Abstract
The invention discloses a pressure early warning wrench. The pressure early warning wrench comprises a wrench handle 1 and a wrench head 2 connected with the wrench handle 1 and is characterized in that an accommodating hole and a setting button are arranged on the wrench handle 1; a battery, and a liquid crystal display screen, a buzzer and a control chip, connected with the battery, are arranged in the accommodating hole; a pressure sensor 4 connected with the control chip is arranged on the wall of a clamping opening of the wrench head 2; and the liquid crystal display screen, the buzzer and the setting button are all connected with the control chip.
Description
Technical field
The present invention relates to a kind of instrument, particularly a kind of pressure early warning spanner.
Background technology
Spanner is the common tool of a kind of flight-line maintenance, for dismounting screw, but some mechanical ratio are more accurate, thus the torsion that bears of some precision screw is limited, exceed and screw thread may be caused damage, so that design a spanner can reported to the police when soon exceeding predetermined torsion.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of pressure early warning spanner.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of pressure early warning spanner, including spanner handle and the driving end that is connected with spanner handle, it is characterized in that: described spanner handle is provided with accommodation hole and button groups, this accommodation hole is provided with battery and the buzzer being connected with battery and control chip, the wall of the bayonet socket of described driving end is provided with the pressure transducer being connected with control chip, and described buzzer, button groups are all connected with control chip.
Hold hole place and be provided with cover plate.
Described button groups includes some groups of pressure value buttons.
The invention has the beneficial effects as follows: the present invention includes spanner handle and the driving end being connected with spanner handle, it is characterized in that: described spanner handle is provided with accommodation hole and button groups, this accommodation hole is provided with battery and the buzzer being connected with battery and control chip, the wall of the bayonet socket of described driving end is provided with the pressure transducer being connected with control chip, described buzzer, button groups is all connected with control chip, pass through said structure, user can arrange the reading of predetermined alarm pressure by settings button, the pressure recorded can be passed to control chip by pressure transducer, when in assembling process, the pressure that pressure transducer detects exceed this reading after control chip can control buzzer send drip drip an acoustic alarm, thus ensure that will not exceed default pressure because of accident avoids damaged screws, and can Normalization rule person reach to need pressure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, the invention discloses the driving end 2 including spanner handle 1 and being connected with spanner handle 1, described spanner handle 1 is provided with accommodation hole and button groups 3, this accommodation hole is provided with battery and the buzzer being connected with battery and control chip, the wall of the bayonet socket of described driving end 2 is provided with the pressure transducer 4 being connected with control chip, and described buzzer, button groups 3 are all connected with control chip.
As it can be seen, hold hole place to be provided with the cover plate 5 in capping accommodation hole. Described button groups 3 includes some groups of pressure value buttons.
Buzzer, settings button and control chip are all customary components, thus specifically do not describe.
A kind of pressure early warning the spanner above embodiment of the present invention provided, it is described in detail, principles of the invention and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method and the core concept thereof of the present invention; Simultaneously for one of ordinary skill in the art, according to the thought of the present invention, all will change in specific embodiments and applications, in sum, this specification content should not be construed as limitation of the present invention.
