Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solution of the present invention.Following embodiment is only used for
Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
First embodiment:
It please refers to Fig.1 to Fig.3, a kind of waterproof test equipment 10 with static(al) locking device, including test equipment 700,
Backing plate 100, pulling plate 200, hollow jack 600 and lock 300.Specifically, test equipment 700 is the tubbiness of cover plate 710
Body is loaded with test fluid in test equipment 700, and test fluid generally selects colored water or common domestic water, for testing drag-line
500 watertightness.Backing plate 100 is arranged on the cover board 710 of test equipment 700, and the middle part of backing plate 100 offers via hole 110.It draws
Plate 200 is located at the surface of backing plate 100, offers through-hole 210 on pulling plate 200.One end of drag-line 500 is fixed on test equipment
700 it is interior, the other end of drag-line 500 is fixed on pulling plate 200 after passing through the via hole 110 on backing plate 100.Hollow jack
600 are arranged on backing plate 100.The mandril 610 of hollow jack 600 can press against the lower end surface of backing plate 100.Lock 300 is worn
It is inserted in through-hole 210.Pulling plate 200 and lock 300 can be along 210 relative motions of through-hole.Lock 300 can consolidate pulling plate 200
It is fixed.When needing to carry out waterproof test test to drag-line 500, it first is internally embedded test test paper in drag-line 500, then will draw
One end of rope 500 is fixed in test equipment 700, and the other end of drag-line 500 is solid after the via hole 110 on backing plate 100
It is scheduled on pulling plate 200.Then start hollow jack 600, the top of pulling plate 200 is sent to predetermined by the mandril 610 of hollow jack 600
Position then can carry out waterproof test test to drag-line 500.In 500 waterproof test test process of drag-line, when hollow very heavy
After the top of pulling plate 200 is sent to predetermined position by top 600, then the position of pulling plate 200 can be locked by lock 300, pass through locking
Device keeps the original test pulling force of drag-line 500, thus off-loadable jack.After completing test, by drag-line 500 from test equipment
It is taken out in 700, by observing test paper situation, then can determine whether the watertightness of drag-line 500.
Lock 300 includes insertion rod 310 and detent component 320.Insertion rod 310 is plugged in through-hole 210, and is inserted into
The bottom end of bar 310 is fixed on backing plate 100.Mounting hole 311 is arranged in the side wall at the top of insertion rod 310.Detent component 320 is arranged
In mounting hole 311.Detent component 320 has elasticity, can stretch along mounting hole 311 and expose to mounting hole 311.Detent group
Part 320 includes tongue 321 and elastic component 322.Tongue 321 is arranged in mounting hole 311.322 one end of elastic component and mounting hole 311
Bottom connection, other end connect with tongue 321.The end of tongue 321 exposes to mounting hole 311, and tongue 321 can installed
Hole 311 is slided, and the end of the close backing plate 100 of tongue 321 is wedge shape 323.In use process, pulling plate 200 is in hollow jack
It is moved up under the top power of 600 mandril 6100, pulling plate 200 is slowly close to detent component 320, when pulling plate 200 and tongue 321 connect
After touch, since the end of the close backing plate 100 of tongue 321 is wedge shape 323, pulling plate 200 is then pushed during moving up
Tongue 321 move to the direction close to mounting hole 311 up to being pushed onto mounting hole 311, when pulling plate 200 be sent to by top it is pre-
When positioning is set, tongue 321 exposes to mounting hole 311 in the effect of elastic component 322 again, so that pulling plate 200 be prevented to transport downwards
It is dynamic.In the present embodiment, elastic component 322 is preferably spring.
In the present embodiment, tongue 321 far from the end of backing plate 100 is vertically arranged with extension rod for operating easily,
324.The length of extension rod 324 is greater than the thickness of pulling plate 200.Leader 325, and handle 325 are horizontally arranged on extension rod 324
Expose to mounting hole 311.It, then can be to the direction squeeze grip 325 close to insertion rod 310, tongue when pulling plate 200 unlocks
321 can be pressed into mounting hole 311, and pulling plate 200 then smoothly can unlock and decline.
In the present embodiment, in order to keep 200 stability under loading of pulling plate, there are two locks 300, and two locks 300 are right
The two sides that drag-line 500 is set claimed, in the specific use process, the quantity of lock 300 can as needed depending on.
The specifically used method of the above-mentioned waterproof test equipment 10 with static(al) locking device:
When needing to carry out waterproof test test to drag-line 500, it first is internally embedded test test paper in drag-line 500,
One end of drag-line 500 is fixed in test equipment 700 again, other end is fixed on drawing after passing through the via hole 110 on backing plate 100
On plate 200.Then starting hollow jack 600, the top of pulling plate 200 is sent to predetermined position by the mandril 610 of hollow jack 600,
Can then waterproof test test be carried out to drag-line 500.In 500 waterproof test system testing of drag-line, pulling plate 200 is hollow thousand
It is moved up under the top power of 600 mandrils 610 of jin top, pulling plate 200 is slowly close to detent component 320, when pulling plate 200 and tongue 321
After contact, pulling plate 200 then pushes tongue 321 to be moved to the direction close to mounting hole 311 until complete during upper movement
Total pressure enters in mounting hole 311, when pulling plate 200 is sent to predetermined position by top, tongue 321 elastic component 322 effect, it is again outer
It is exposed to mounting hole 311, so that pulling plate 200 be prevented to move downward.It, then can be to close to insertion rod when pulling plate 200 does not need locking
310 direction squeeze grip 325, tongue 321 can be then pressed into mounting hole 311, and pulling plate 200 then can smoothly decline.It completes
After test, drag-line 500 is taken out out of test equipment 700, by observing test paper situation, then can determine whether the watertightness of drag-line 500.
The above-mentioned waterproof test equipment 10 with static(al) locking device, including test equipment 700, backing plate 100, pulling plate 200,
Hollow jack 600 and lock 300 are loaded with test fluid in test equipment 700, and test fluid is generally colored water, for surveying
Try the watertightness of drag-line 500.In 500 waterproof test system testing of drag-line, when hollow jack 600 send the top of pulling plate 200
To after predetermined position, then the position of pulling plate 200 can be locked by detent component 320, to keep the original test of drag-line 500
Pulling force, and then off-loadable jack.Since the end of the close backing plate 100 of tongue 321 is wedge shape 323, pulling plate 200 is then being moved up
Tongue 321 is smoothly pushed to be moved to the direction close to mounting hole 311 until being pressed into mounting hole 311 in dynamic process.When
When pulling plate 200 does not need locking, then peace can be then pressed into the direction squeeze grip 325 close to insertion rod 310, tongue 321
It fills in hole 311, pulling plate 200 then can smoothly decline.
