The utility model adopts following technical scheme:

The utility model provides a kind of sound test fixture, comprising: two main folder arms, one jig arm and a coupling shaft; The upper end of described main folder arm and time jig arm is equipped with a through hole, and described through hole is crossed and is socketed in respectively on the described coupling shaft, and described main folder arm and time jig arm pivot along described coupling shaft; The lower end of described main folder arm is provided with the lock body installing plate of the tested lock body of an installation, and the lower end of described jig arm is provided with the snap close installing plate of an installation snap close; Described tested lock body and snap close with the pivot of described main folder arm and time jig arm, are finished the action of locking thereby described snap close clashes into the dead bolt of described tested lock body respectively.

Preferably, described coupling shaft is suspended on the house beam.

Preferably, the fixing some main folder arm baffle plates of a side of two described main folder arms.

Preferably, the lower end of described main folder arm is provided with at least one distance rod, and the lower end of described jig arm is provided with a photoelectric sensor, the measurement range by described photoelectric sensor in the stroke that described distance rod pivots with the main folder arm.

Preferably, also comprise a distance measurement ruler, described distance measurement ruler is supported between described main folder arm bottom and described the jig arm bottom, makes described main folder arm and described jig arm form angle.

Preferably, also comprise a balancing weight, described balancing weight is arranged on the lower end of described jig arm.

Owing to having adopted above-mentioned technology, compared with prior art, sound test fixture of the present utility model can effectively be implemented lock sound test of automobile door lock, has effectively avoided the noise that the test fixture vibrations bring in the test process, guarantee test data accurately and test process safe and reliable.

Further specify the utility model below in conjunction with drawings and Examples.

Embodiment

Introduce specific embodiment of the utility model below by Fig. 1 to 3.

Shown in Fig. 1 to 2, a kind of sound test fixture of the present utility model comprises: two main folder arms 2, one jig arm 6 and a coupling shaft 1; The upper end of described main folder arm 2 and time jig arm 6 is equipped with a through hole, and described through hole is crossed and is socketed in respectively on the described coupling shaft 1, and described main folder arm 2 and time jig arm 6 pivot along described coupling shaft 1; The lower end of described main folder arm 2 is provided with the lock body installing plate 3 of the tested lock body 10 of an installation, and the lower end of described jig arm 6 is provided with the snap close installing plate 7 of an installation snap close 5; Described tested lock body 10 and snap close 5 are respectively with the pivot of described main folder arm 2 and time jig arm 6, thereby the dead bolt of the described tested lock body 10 of described snap close 5 bumps is finished the action of locking.

Described coupling shaft 1 is suspended on the house beam, can effectively avoid the noise that test fixture produces in the test process.Article two, fixing some main folder arm baffle plates 4 of a side of described main folder arm 2 prevent that time jig arm 6 from passing between two described main folder arms 2.The lower end of described main folder arm 2 is provided with distance rod, and the lower end of described jig arm 6 is provided with a photoelectric sensor, the measurement range by described photoelectric sensor in the stroke that described distance rod pivots with main folder arm 2.

Among Fig. 1, the bottom sheet of main folder arm 2 is lock body installing plate 3, and the above installs tested lock body 10.The bottom sheet of inferior jig arm 6 is snap close installing plate 7, and the above installs snap close 5.

Among Fig. 2, coupling shaft 1 is suspended on the suspension cord, and housing is main folder arm 2, and the centre is main folder arm baffle plate 4, and a middle arm is time jig arm 6, is furnished with balancing weight 8, makes normally complete locking of lock body.

The utility model also comprises a balancing weight 8, and described balancing weight 8 is arranged on the lower end of described jig arm 6.

As shown in Figure 3, in actual the use, the utility model also comprises a distance measurement ruler 9, and described distance measurement ruler 9 is supported between described main folder arm 2 bottoms and described jig arm 6 bottom, makes described main folder arm 2 and described jig arm 6 formation angles.

Sound test fixture of the present utility model is arranged in the quiet room.This unit clamp mainly comprises main folder arm 2, inferior jig arm 6.Link to each other with suspension cord by coupling shaft, suspension cord hangs on the fixed cross beam.The lock body installing plate of main folder arm 2 lower ends can be fixed tested lock body 10.The snap close installing plate 7 of inferior jig arm 6 lower ends can be fixed tested lock body 10 corresponding snap closes 5.The position that can be used for mounting distance dip stick 9 is arranged respectively on the primary and secondary jig arm, behind the mounting distance dip stick 9, formed an angle between main folder arm 2 and the inferior jig arm 6, after taking out fast distance measurement ruler 9 from the side, main folder arm 2 and time jig arm 6 are in being returned to the equilibrium position process, thereby snap close 5 can strike the dead bolt of lock body and finish the action of locking, the sound that produces in the process of locking to computing machine, and can go out sound figure and data with software analysis by the microphone receiving record of sound testing apparatus.

This Special-purpose testing jig is owing to hanging on the crossbeam with rope, the primary and secondary jig arm 6 of anchor clamps is in the plane because of Action of Gravity Field, and place distance measurement ruler 96 of primary and secondary jig arm, there is certain difference in height in two jig arm with equilibrium position separately, take out distance measurement ruler 9, when primary and secondary jig arm 6 is returned to same plane at short notice, produces lock body and agree with mutually the sound that sends with snap close 5, guaranteed the accuracy of the sound of surveying.In addition, the weight of main folder arm 2 is installed with balancing weight 8 substantially with reference to the weight of arrangements for automotive doors on the inferior jig arm 6, makes normally complete locking of lock body.According to different lock bodies, snap close 5, the length of adjustable range dip stick 9 can guarantee that all tested lock bodies 10 lock with identical speed, guarantees consistance, the science of test, also can make and same lock body be tested by different speed, and compare.

In summary, owing to having adopted above-mentioned material and technological innovation, sound test when sound test fixture of the present utility model can be implemented smoothly automobile door lock and locks is effectively avoided because test fixture in the measuring process produces unnecessary noise in test process, and safe, easy.
