To illustrate and understand the utility model rather than to limit the utility model.
Embodiment：
As depicted in figs. 1 and 2, the utility model provides a kind of anti-gas-leak for watch back shell air-tightness and detects dress
It puts, including airtightness test table 1, dorsal shield fixing device 2, the dorsal shield fixing device 2 is installed on the airtightness test table 1
Including the placement block 201 being mounted on airtightness test table 1 and the frame shape briquetting 203 for being hinged on 201 top side of placement block, the peace
It puts 201 center of block and is equipped with holding tank 202, it is close that placement 201 top of block and 203 top of frame shape briquetting are mounted on rubber buffer
Packing 204 makes watch back shell when by frame shape briquetting 203 and placement block 201 common extruding force, rubber buffer gasket 204
The cushion effect for the buffering that is pressurized to watch back shell one, so as to be unlikely to deform wristwatch case or be subject to crushing, and watch back shell bottom surface
It is pressed on the rubber buffer gasket 204 for placing 201 top of block, so as to which the air-tightness for making holding tank 202 is guaranteed, holds
Receive slot 202 will not gas leakage or into gas without foundation, make testing result relatively reliable.
As shown in Fig. 2, being equipped with pressure test device 4 on the placement block 201, the pressure test device 4 includes gas
Pressure table 401 and the air pressure detection needle 402 being connect with 401 one end of air gauge, the air gauge 401, which is mounted on, places block 201
Outside, the air pressure detection needle 402 are inserted into holding tank 202, and air pressure detection needle 402 can detect the gas pressure in holding tank 202
Power, when the air-tightness for detecting watch back shell, if watch back shell gas leakage, gas can be transmitted by air pressure transfer device 5
It, at this moment can be according to air gauge so as to increase the air pressure in holding tank 202 in holding tank 202 immediately below to watch back shell
401 variation judgement watch back shell air-tightness is bad, if to air gauge 401 in the time after detection before watch back shell detection
Air pressure registration does not change always, at this moment can judge that watch back shell air-tightness is good.
As shown in Fig. 2, 201 top of the placement block is equipped with several screw holes 205, if being inserted on the frame shape briquetting 203
The dry screw rod 206 to match with screw hole 205, by 206 precession screw hole 205 of screw rod, can make placement block 201 and frame shape briquetting 203
Wristwatch case is tightly pushed down, wristwatch case is made not moved when air-leakage test is received, so as to ensure that holding tank 202
Interior sealing and the accuracy of testing result, 206 precession screw hole 205 of screw rod is deeper, and frame shape briquetting 203 is to the compression of wristwatch case
Power is bigger, can turn screw rod 206 adjust the pressing force that is subject to of water meter housing, to prevent damaging by pressure or by wristwatch case compressive strain.
As shown in Figure 1, being equipped with oil cylinder 3 by supporting rack 7 on the airtightness test table 1,3 bottom of oil cylinder passes through
Vertical piston rod 301 passes through 7 top of supporting rack to be connected with installation frame 302, and atmospheric pressure is equipped in the installation frame 302
Generating means 6,6 bottom of atmospheric pressure generating means are connected with positioned at the air pressure transfer device 5 placed right over block 201,
Oil cylinder 3 drives vertical piston rod 301 to extend so as to make installation frame 302 that atmospheric pressure generating means 6 and air pressure be driven to transmit dress
It puts 5 to move downward, air pressure transfer device 5 is made to be contacted with the watch back shell being fixed on placement block 201, atmospheric pressure generating means
6 ventilate in air pressure transfer device 5, if watch back shell gas leakage, pressure test device 4 can detect that variation, if watch back shell
Air-tightness is good, then pressure test device 4 does not change.
As shown in Fig. 2, the air pressure propagation medium of atmospheric pressure generating means 6 is air, it is -20~20KPa to make pressure range,
Pressure system is made as the indispensable ancillary equipment of pressure measurement, is constantly subjected to legal professional metrological service and industrial and mining enterprises thermal technology
Portable pressure in the market can be used in metering and the concern and attention of meter control engineering staff, atmospheric pressure generating means 6 here
Pump, makes pressure range：- 95~250KPa, weight about 0.6Kg, it is simple, light, easy to operate, it is light-weight, it is easy to operate.
As shown in Figures 2 and 3, the air pressure transfer device 5 includes center tracheae 501, the middle set gas that length is sequentially reduced
Pipe 502 and housing tracheae 503, center tracheae 501, middle set tracheae 502 and 503 three of housing tracheae is coaxial and three all in an axial direction
It moves up and down.501 top of center tracheae connect with atmospheric pressure generating means 6, the center tracheae 501 and is set in
Between the middle set tracheae 502 in the outside of motive pipe 501, middle set tracheae 502 and the housing tracheae for being set in middle 502 outside of set tracheae
Restore sealing ring 504 by elasticity between 503 tops to be tightly connected, because of center tracheae 501, middle set tracheae 502 and housing
The elemental height of 503 bottom surface of tracheae is different, so when being all pressed on watch back shell three tracheae bottoms, elasticity restores close
Seal 504 can be pressurized contraction, and rise in piston rod 301 and shrink, and when center tracheae 501 also rises, elasticity restores sealing
Circle 504 makes middle set tracheae 502 and housing tracheae 503 return to initial position, so as to ensure that the standard of detection watch back shell every time
True property.
As shown in Fig. 2, the bottom surface level height of the center tracheae 501, middle set tracheae 502 and housing tracheae 503 is successively
It reduces, when vertical piston rod 301 extends downwardly elongation, housing tracheae 503 first contacts watch back shell, after being closely affixed, middle set
The front and rear contact watch back shell in bottom end of tracheae 502, center tracheae 501, the bottom end of three tracheaes is in sealing contact with watch back shell,
So as to make air-tightness relatively reliable, the gas for flowing to watch back shell from tracheae is made not leaked from the gap of tracheae and watch back shell
Out, serious forgiveness is increased, it is only necessary to which any one tracheae and watch back shell are in sealing contact in three tracheaes, so that it may be completed
The air-leakage test of watch back shell extends the maintenance cycle of detection device, so as to reduce cost.
As shown in Fig. 2, the bottom end of center tracheae 501, middle set tracheae 502 and housing tracheae 503 is mounted on ring packing
Rubber press 505, when so that three tracheae bottom ends is pressed on watch back shell, watch back shell and tracheae will not damage, in extending
Motive pipe 501, middle set 503 service life of tracheae 502 and housing tracheae, and ring packing rubber block 505 also makes center tracheae
501st, the bottom end of middle set tracheae 502 and housing tracheae 503 is closely attached on watch back shell, ensure that watch back shell air-tightness is examined
The stability and accuracy of survey.
In conclusion the utility model is mainly characterized by：
（1）Air-tightness is more preferable when the design of center tracheae, middle set tracheae and housing tracheae makes the tracheae be contacted with watch back shell,
Serious forgiveness is increased, even if the damage of any one tracheae nor affects on the detection of air-tightness, extends the repair week of detection device
Phase saves testing cost；
（2）The design of rubber buffer gasket and ring packing rubber press makes watch back shell by more stable fixation, hand
Table dorsal shield is hardly damaged or deforms, and connection sealing is good, and the air-leakage test result of watch back shell is relatively reliable.
