Embodiment
By describing technology contents of the present utility model, structural attitude in detail, being reached object and effect, below hereby exemplify embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1 to Fig. 2, the utility model proving installation 100 for test headphone 200 wear 201 and pronunciation portion 202 between propelling power and withdrawal force.
Proving installation 100 comprises support 11, is installed in clamping device 12, propulsion system 13 and push-pull effort counting device 14 on support 11.Clamping device 12 wears 201 at support 11 for fixed clamp headphone 200.Propulsion system 13 are for clamping the pronunciation portion 202 of headphone 200, and produce and be used as power with the pronunciation portion 202 of push-and-pull headphone 200, make it with propulsion system 13, make arc sliding, to regulate the length of wearing 201.Push-pull effort counting device 14 is connected in propulsion system 13, for the numerical value of survey record push-pull effort.
Thus, manually push-and-pull pull bar 136, drives arc synchronized piece 135 in the synchronous interior slip of dragging track 112, drives push-and-pull fixed block 132 synchronous slides, thereby drive arcuate movement piece 131 in the interior slip of arc sliding track 111 by contiguous block 34.
The contiguous block 134 of push-and-pull counter 14 and propulsion system 13 is connected, so that record the numerical value of the push-pull effort of propulsion system 13.In the present embodiment, on support 11, be provided with two groups of reference columns 121.
During the work of the utility model proving installation, first say that headphone 200 is contained on support 11, headphone 200 to wear 201 two ends fixing by one group of reference column 121 respectively, wearing of one end to be tested 201 fixed by clamping device 12, wear 201 and put into crack 126, again grip block 124 is slipped into loose slot 1221 from guide block 123 tops, and to fixed block 122 directions, slide when gliding, while sliding into loose slot 1221 bottom, grip block 124 stretches out loose slot 1221, supports 201 one end that are connected with pronunciation portion 202 of wearing of clamping headphone 200; The pronunciation portion 202 of headphone 200 is placed in the locking groove 1321 on push-and-pull fixed block 132 with the one end of wearing 201 connections, and rotary lock piece 133 is fixed.
Then, push-and-pull pull bar 136, drive arc synchronized piece 135 along being synchronized with the movement the interior slip of track 112, and driving arcuate movement piece 131 along the interior slip of arcuate movement track 111 by contiguous block 134, the push-and-pull fixed block 132 and the locking block 133 that are fixed on arcuate movement piece 131 drive the pronunciation portion 202 of headphone 200 and wear one end propelling of 201 connections or pull out and wear 201.Meanwhile, be connected to push-pull effort register 14 on contiguous block 134 and record the value of push-pull effort, complete test.
In sum, the utility model proving installation is by arranging arc synchronized piece 135 and being synchronized with the movement that track 112 coordinates and arcuate movement piece 131 and arcuate movement track 111 coordinate, realized the test to the push-pull effort on arc track, mechanism is simple, handled easily.
