Brief description of the drawings
Fig. 1 is the schematic perspective view of an embodiment of the utility model device for detecting length；
Fig. 2 is the circuit diagram of display module in the utility model device for detecting length.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, device for detecting length of the present utility model includes：Survey mass 10, the first contact 20, the second contact 30
And display module 40.
The survey mass 10 is used to carry out crossbeam to the length of measured object.Specifically, the survey mass 10, which has, weighs quilt
The whether satisfactory thickness of thing length is surveyed, meanwhile, the logical of through-thickness extension is offered on the side of the survey mass 10
Hole 11, the through hole 11 penetrate the side that the survey mass 10 is oppositely arranged.So that, can be by measured object longitudinally when measuring
Stretch into from one end of the through hole 11, when the inserting end of measured object can not stretch out from the other end of the through hole 11, then show
The length violation of measured object closes size requirement, otherwise, shows that the length of measured object is met the size requirements.
The contact 30 of first contact 20 and second is used to respond the stretching state of measured object and can not stretch out state, and can
The electric signal corresponding to output in the state of difference.Specifically, first contact 20 is set as follows, and it is against simultaneously
One end of the through hole 11 is covered, the other end of the through hole 11 is connected with external environment condition, so that the through hole 11 is another
End is available for measured object to stretch into.Meanwhile first contact 20 under a resilient force along above-mentioned thickness direction with described
Two contacts 30 are electrically connected with, as long as second contact 30 meets to keep with first contact 20 under above-mentioned resilient force
Electric connection, to its specific set-up mode without limiting.
So as to when after measured object stretches into through hole 11 and when can not stretch out, the contact 30 of the first contact 20 and second is in bullet
Property the lower clock of power effect keep being electrically connected with, when measured object stretches into through hole 11 and can stretch out, the part of stretching and described the
One contact 20 is in contact, and promotes it to be moved along above-mentioned thickness direction, it is separated with second contact 30, so realizes
The contact 30 of first contact 20 and second stretches out state to measured object and can not stretch out the response of state.In addition, testing
After, under the resilient force, first contact 20 moves to initial position, continues to keep and second contact
30 electric connection.
In one embodiment, first contact 20 can be the first copper billet, and second contact 30 can be the
Two copper billets.In present embodiment, first copper billet is located at the side of the survey mass 10, and second copper billet is located at the survey
The both ends of gauge block 10, and be arranged side by side with the survey mass 10, the width of first copper billet is more than the width of the survey mass 10
Degree.So as to when after measured object stretches into through hole 11 and when can not stretch out, first copper billet is in contact with second copper billet at both ends；
When measured object stretches into through hole 11 and can stretch out, second copper billet at first copper billet and both ends is separated.
Further, the length-measuring appliance also includes pedestal 50, and it is used for the survey mass, the first copper billet and second
The installation of copper billet is fixed.Preferably, the pedestal 50 can be bakelite.
Specifically, the pedestal 50 has front end face and top surface, is provided with sunk part on the front end face, it causes institute
It is substantially in concave shape to state pedestal 50, is set on the top surface fluted.Wherein, the survey mass and second copper billet at both ends house
It is installed in the sunk part, the second copper billet and the front end face at the survey mass and both ends can be fixed by screw
Connection, first copper billet are actively contained in the groove, meanwhile, it is provided between first copper billet and the groove
Elastic component, the elastic component provide the elastic force of above-mentioned thickness direction.Preferably, the elastic component is spring.
In addition, in order that first copper billet and the second copper billet exported under different conditions corresponding to electric signal, both ends
The second copper billet on be connected to the wire of transmitting telecommunication number.Cabling channel is additionally provided with the pedestal 50, the cabling channel is opened
Located at the both sides of the groove, the cabling channel is used to house the wire.
As shown in Fig. 2 the display module 40 be used for receive the contact 30 of the first contact 20 and second be electrically connected with
And electric signal when disconnecting, and show measurement result according to the electric signal.
In one embodiment, the display module 40 includes qualified indicator lamp L2, unqualified indicator lamp L1, to described
The first relay J2 that qualified indicator lamp L2 is controlled and the second relay being controlled to the unqualified indicator lamp L1
Device J1.The qualified indicator lamp L2 can select green light, and the unqualified indicator lamp L1 can select red colored lamp.Shown in Fig. 2
In circuit, the normality of the first relay J2 is switch J21 closures, switch J22 open circuits；The second relay J1's is normal
State is switch J11 closures, switch J12 open circuits.
So as to, after the display module 40 is powered, when measured object length is inadequate, under the first copper billet act in elasticity and
Two the second copper billets are in contact, and K closures are switched in circuit shown in Fig. 2, and switch J11 closures switch J12 open circuits, and switch J21 is closed
Close, switch J22 open circuits, so as to which red colored lamp is bright, green light does not work；When measured object length composite demand, the first copper billet is tested
Thing promotes to be separated with two the second copper billets, and K is switched in circuit shown in Fig. 2 and is disconnected, and switch J11 open circuits, switch J12 closures, is opened
J21 open circuits are closed, switch J22 closures, so as to which green light is bright, red colored lamp does not work.
In summary, the utility model can be detected quickly and easily to the length of electronic product, its detection efficiency
Height, and accuracy of detection is good, fully meets the demand of enterprise's production.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can be realized in other embodiments in the case where not departing from spirit or scope of the present utility model.Cause
