Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
Referring to Fig. 3 to Fig. 6, a kind of measurement uses connection assembly, including outer tube 102, inner tube
101, detent mechanism, nut 303, locking cap 301 and lock ring 302, outer tube 102 is sliding
Dynamic be socketed in inner tube 101, and inner tube under external force can along outer tube axially reciprocating,
Inner tube 101 outer wall is provided with more than one breach, and each breach connects assembly from different measurements
Setting height is corresponding so that the measurement connection assembly after La Shen can by breach adjust to
Meet different setting height requirements；Detent mechanism is fixed on outer tube 102 outer wall, this localization machine
Structure has a positioning rod 304, and this location bar 304 is used for and described breach snap-fit engagement；Nut
303 are fixed on outer tube 102 top, and its internal diameter is axially gradually reduced from top to bottom along outer tube 102；
Locking cap 301 is slidably socketed in inner tube 101 outer wall, has rotating part 3011 and multiple connection
Portion 3012, this connecting portion 3012 stretches out along the bottom circumference of rotating part 3011, is used for and spiral shell
Cap 303 is threaded；Lock ring 302 is slidably socketed in inner tube 101 outer wall, and its top is fixed
On rotating part 3011 inwall, its bottom is stretched out by locking cap 301 bottom.
During use, by inner tube 101 along outer tube 102 be pulled to axially upwards suitably height time, rotate
Locking cap 301 makes it drive lock ring 302 in the lump towards near the spiral shell being fixed on outer tube 102 top
Cap 303 moves, until the connecting portion 3012 of locking cap 301 is threadeded with nut 303,
During this, the internal diameter due to nut 303 is axially gradually reduced from top to bottom along outer tube 102, makes
Nut 303 possesses the inwall of inclination, is therefore being screwed in by the connecting portion 3012 of locking cap 301
Time in nut 303, nut 303 transfixion, its tilt internal wall can be gradually increased lock ring
The pressure of 302, lock onto inner tube 101 on outer tube 102 eventually through lock ring 302, from
And conveniently adjust inner tube 101 height.Additionally, reach to set height adjusting measurement connection assembly
During degree, by the location bar 304 in detent mechanism and the breach on inner tube 101 outer wall
Snap-fit engagement, can very easily inner tube 101 tensile elongation be carried out spacing so that survey
Amount connection assembly meets setting height, afterwards by above-mentioned locking cap 301, lock ring 302
And the cooperation between nut 303, locking inner tube 101 again, it is to avoid inner tube 101 was using
Journey moves, thus improves measurement and connect assembly stability under setting height, to improve
Measure precision.
Realize the snap-fit engagement between location bar 304 and breach for convenience, preferred as one
Scheme, the detent mechanism in the present embodiment also has mounting seat 307, button 306 and spring 305,
Wherein, mounting seat 307 is removably fixedly sheathed on outer tube 102, mounting seat 307
Bottom have a groove 3071, button 306, location bar 304 along the direction being perpendicular to outer tube
Slide successively along groove 3071 notch to the direction of groove 3071 bottom land with spring 305 and be connected to
In groove 3071, button 306 and location bar 304 are one-body molded, and enclose receiving outer tube
The port of 102, one end of spring 305 abuts with location bar 304, the other end of spring 305
It is connected with groove 3071 bottom land.During stretching inner tube 101, spring 305 compresses,
Breach on inner tube 101 outer wall is mounted opposite seat 307 and moves, when breach is positioned at groove 3071
Time interior, spring 305 extends, and drives location bar 304 to move, and makes location bar 304 through outward
Pipe 102 arm stretches in the breach of inner tube 101, thus limits inner tube 101 height, after making stretching
Measurement connection assembly meet setting height.Additionally, mounting seat 307 in the present embodiment
Top is used as handle portion 3072, it is simple to user takes and holds.
The connection of connecting portion 3012 with nut 303 in order to strengthen locking cap 301, and prevent
There is bow tie in locking cap 301, as a kind of preferred version, also in location in the present embodiment
Mechanism is additionally arranged a plasticity limited location snap ring 310, and makes outside limited location snap ring 310 is socketed on without hesitation
Pipe 102 is also fixed on the top of handle portion 3072, and the connecting portion 3012 of above-mentioned locking cap 301
Bottom outer wall outwardly convex forms barb, and this barb can be with clamping bottom plasticity limited location snap ring 310
Coordinate, thus prevent locking cap 301 from turning round, strengthen Consumer's Experience.And set up in handle portion and mould
Property limited location snap ring 310, can make user or manufacturer only need to be replaced plasticity limited location snap ring 310
And the maintenance to product can be realized without dismantling detent mechanism.
In order to avoid the abrasion of outer tube 102 bottom, and improve the accuracy of measurement, as one
Preferred version, is also provided with rustless steel foot head 308 in outer tube 102 bottom in the present embodiment, and
And dismantle rustless steel foot head 308 for convenience, so that measurement connects assembly and can set with other
Standby with the use of, the rustless steel foot head 308 in the present embodiment be removably be fixed on outside
Pipe 102 bottom.As it is shown in figure 9, when using base station mode operations, can be by stainless
Steel foot head 308 disassembles, in order to measure with connecting assembly outer tube 102 with foot rest 401 even
Connect, so that launching antenna 501 can meet antenna height requirement.Further, in order to just
Launch antenna 501 in installing, the present embodiment is measured with the inner tube 101 top tool connecting assembly
Have and launch the thread that antenna 501 docks.And in order to prevent because often dismantling rustless steel foot head 308
And cause the most caducous situation of rustless steel foot head 308 to occur, the present embodiment also exists
It is additionally arranged lock washer 309 between outer tube 102 bottom and rustless steel foot head 308.
The range of application of assembly is connected, as a kind of preferred version, this reality in order to improve measurement
Execute in example measurement connect assembly inner tube 101 outer wall be provided with may be used for measure object
The scale of length, so that measurement connection assembly can be not only used for specialized engineering and measures, such as figure
Shown in 8, it is also possible to measure for conventional length, as shown in Figure 7.
And in order to reduce measurement connect assembly weight, with reduce user use during tired
Lao Du, as a kind of preferred version, will measure with the outer tube 102 connecting assembly in the present embodiment
External diameter is set to 27mm, and inner tube 101 external diameter is set to 18.5mm, this measurement connection group
Part can be connected with outside small-sized measurement equipment, to meet the demand of different crowd, same with this
Time, owing to outer tube 102 external diameter and inner tube 101 external diameter of measurement connection assembly are all significantly less than
The outer tube external diameter of centering rod and inner tube external diameter in the market, therefore the measurement in the present embodiment is used
Connect lightweight packages substantially to reduce, thus strengthen Consumer's Experience.
It will be apparent to those skilled in the art that can technical scheme as described above and structure
Think, make other various corresponding changes and deformation, and all these changes and deformation
Within all should belonging to the protection domain of the claims in the present invention.
