Further, the screw rod includes the threaded portion of front end and the polished rod portion of rear end, the length and screw thread of described sleeve pipe
The surface of the equal length in portion, the polished rod is equipped with scale, and described sleeve pipe is transparent configuration.
Further, the pushing block is equipped with external screw thread, and connect with bush whorl, and the end of pushing block is equipped with operation
Hole.
Further, the pushing block is piston, is arranged with sealing ring, by sealing ring and sleeve connection, piston
Rear end is equipped with handle hole or threaded hole.
Preferably, the front end of the sleeve is equipped with inner core, and inner core and sleeve are integrally formed；The middle part of inner core is equipped with and light
The perforation that bar portion matches.More preferably, sealing ring is equipped in perforation, and inner seal ring is placed on outside polished rod portion.
The utility model has the beneficial effects that the utility model can quickly position the spiro rod length for protruding into blind hole,
Statistics is convenient and error is small.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the present embodiment.
Fig. 2 is a kind of schematic cross-sectional view of the present embodiment.
Fig. 3 is another schematic cross-sectional view of the present embodiment.
Appended drawing reference includes:
1 --- sleeve；2 --- limited part；3 --- casing；4 --- screw rod；5 --- pushing block；41 --- polished rod portion；
42 --- threaded portion；6 --- sealing ring.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing.As shown in Figure 1 to Figure 3.
Embodiment: a kind of for measuring the gauge of blind hole depth a, comprising: sleeve 1, one end of sleeve 1 are connected with set
Pipe 3, casing 3 are connected to sleeve 1, and the screw rod 4 for measurement is socketed in described sleeve pipe 3, and casing 3, spiral shell are stretched out in one end of screw rod 4
The other end of bar 4 passes through casing 3 and gos deep into sleeve 1, and the pushing block 5 for pushing ahead screw rod 4 is equipped in the sleeve 1.
When in use, the exposed one end of screw rod 4 is smaller for the technical program, and first by the insertion blind hole of screw rod 4, then
Casing 3 is abutted against with blind hole；External force is reused on pushing block 5 so that pushing block 5 drive screw rod 4 along casing 3 forward
It is mobile, until the end face of screw rod 4 and the bottom surface of blind hole offset；Finally screw rod 4 is removed from blind hole, to the screw rod being exposed
4 teeth are counted, and at this time by casing 3 as referring to, it is accurate that statistics facilitates.
Further, the side of the sleeve 1 offers side opening, and side opening is connected with for limiting the movement of screw rod 4
Limited part 2, limited part 2 can opposed side apertures movements.
Since the precision of measurement request is higher, after a measurement, screw rod 4 is immovable, to facilitate statistics；In the technical program
Provided with limited part 2, in measurement, limited part 2 leaves screw rod 4；In statistics, limited part 2 is mobile and abuts with screw rod 4,
So that screw rod 4 is limited.Prevent screw rod 4 from moving down in external force dynamic.Screw, bolt etc. can be used in limited part 2, connects with side opening screw thread
It connects.
Further, the screw rod 4 includes the threaded portion 42 of front end and the polished rod portion 41 of rear end, the length of described sleeve pipe 3
Scale is equipped with the surface of the equal length of threaded portion 42, the polished rod, it is preferable that described sleeve pipe 3 is transparent configuration.Casing 3
The materials such as silica gel can be used.Alternatively, the side of casing 3 offers form corresponding with scale hole；With the quarter of convenient reading polished rod
Degree.
Scale is arranged can be with subsidiary, when measurement, and casing 3,41 sleeve pipe 3 of polished rod portion are stretched out in threaded portion 42；Screw thread
The equal length of length and 41 sleeve pipe 3 of polished rod portion that portion 42 is stretched out, therefore when measuring 42 extension elongation of threaded portion, it can also
It is more convenient to use accurate to protrude into the length in the polished rod portion 41 of casing 3 by measuring and determine.
Further, the pushing block 5 is equipped with external screw thread, and is threadedly coupled with sleeve 1, and the end of pushing block 5 is equipped with behaviour
Make hole.
Handle hole can be in cross or quincunx；By screwdriver action advances block 5, pushing block 5 is controlled in sleeve 1
Position.
Further, referring to Fig. 3, the pushing block 5 is piston, is arranged with sealing ring 6, passes through sealing ring 6 and sleeve 1
The rear end of connection, piston is equipped with handle hole or threaded hole.
Pushing block 5 is connected by handle hole, threaded hole and operating stick, and pushing block 5 is pushed to move in sleeve 1, mobile
Meanwhile changing the pressure difference in sleeve 1, threaded portion 42 is released or retracted out of casing 3.
Preferably, the front end of the sleeve 1 is equipped with inner core, and inner core and sleeve 1 are integrally formed；The middle part of inner core be equipped with
The perforation that polished rod portion 41 matches.More preferably, sealing ring 6 is equipped in perforation, and inner seal ring 6 is placed on outside polished rod portion 41.
In the front end of sleeve 1, setting inner core will not shake so that polished rod portion 41 is directed limit when moving in sleeve 1
It is dynamic.In lead-screw 4, pushed using air pressure.Preferably, liquid is filled in sleeve 1.Using hydraulic-driven screw rod 4
It moves more convenient.Liquid basically will not produce volume compression during the work time.Precision is high.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
