Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
Refer to Fig. 3 to Fig. 6, a kind of measurement connection component, including outer tube 102, inner tube 101, positioning mechanism, nut
303, locking cap 301 and lock ring 302, outer tube 102 is slidably socketed in inner tube 101, and inner tube under external force can edge
Outer tube axially reciprocating, 101 outer wall of inner tube are equipped with more than one notch, and each notch is set from different measurements with connection component
Fixed height is corresponding, wants so that the measurement after stretching can be adjusted to meeting different setting heights with connection component by notch
It asks；Positioning mechanism is fixed on 102 outer wall of outer tube, which has a positioning rod 304, the locating rod 304 be used for it is described
Notch is engaged by clamping；Nut 303 is fixed on 102 top of outer tube, and internal diameter is axially gradually reduced from top to bottom along outer tube 102；Lock
Tight cap 301 is slidably socketed in 101 outer wall of inner tube, has rotating part 3011 and multiple interconnecting pieces 3012, the interconnecting piece 3012 is along rotation
The bottom end of transfer part 3011 is circumferentially stretched out, for being threadedly coupled with nut 303；Lock ring 302 is slidably socketed in 101 outer wall of inner tube,
Its top is fixed on 3011 inner wall of rotating part, and bottom end is stretched out by 301 bottom end of locking cap.
In use, rotation locking cap 301 makes its drive when inner tube 101 is pulled to appropriate height along outer tube 102 axially upwards
Lock ring 302 together towards close to be fixed on 102 top of outer tube nut 303 move, until locking cap 301 interconnecting piece 3012 with
Nut 303 is threadedly coupled, and is axially gradually reduced due to the internal diameter of nut 303 along outer tube 102 from top to bottom during this, is made nut
303 have inclined inner wall, therefore when screwing in the interconnecting piece 3012 of locking cap 301 in nut 303, nut 303 is static not
Dynamic, tilt internal wall can be gradually increased the pressure to lock ring 302, and inner tube 101 is lock onto outer tube eventually by lock ring 302
On 102, to facilitate 101 height of adjustment inner tube.In addition, during adjustment measurement connection component reaches setting height,

In on outer tube 102, the bottom of mounting base 307 is provided with a groove 3071, button 306, locating rod 304 along the direction perpendicular to outer tube
It successively slides and is connected in groove 3071 along the direction of 3071 notch of groove to 3071 slot bottom of groove with spring 305,306 He of button
Locating rod 304 is integrally formed, and encloses the port for accommodating outer tube 102, and one end of spring 305 is abutted with locating rod 304, spring
305 other end is connect with 3071 slot bottom of groove.During stretching inner tube 101, spring 305 compresses, on 101 outer wall of inner tube
Notch with respect to mounting base 307 move, when notch is located in groove 3071, spring 305 extend, and drive locating rod 304 fortune
It is dynamic, so that locating rod 304 is passed through 102 arm of outer tube and protrude into the notch of inner tube 101, to limit 101 height of inner tube, makes after stretching
Measurement connection component meets setting height.In addition, the top of the mounting base 307 in the present embodiment is used as handle portion 3072, just
It takes and holds in user.
In order to enhance the interconnecting piece 3012 of locking cap 301 and the connection of nut 303, and prevent locking cap 301 from turning round
Phenomenon is also additionally arranged a plasticity limited location snap ring 310, and make rope as a preferred embodiment in positioning mechanism in the present embodiment
Property limited location snap ring 310 is socketed on outer tube 102 and is fixed on the top of handle portion 3072, and the interconnecting piece of above-mentioned locking cap 301
3012 bottom end outer wall outwardly convexs form barb, which can be engaged by clamping with 310 bottom of plasticity limited location snap ring, to prevent from locking
Tight cap 301 turns round, and enhances user experience.And plasticity limited location snap ring 310 is added in handle portion, it can be used family or manufacturer only need to be to modeling
Property limited location snap ring 310 be exchanged without disassembly positioning mechanism maintenance to product can be realized.
In order to avoid the abrasion of 102 bottom end of outer tube, and improve the accuracy of measurement, as a preferred embodiment, this implementation
It also is provided with stainless steel feet head 308 in 102 bottom end of outer tube in example, and dismantles stainless steel feet head 308 for convenience, so that measurement
It can be used cooperatively with other equipment with connection component, the stainless steel feet head 308 in the present embodiment is removably fixed
In 102 bottom end of outer tube.As shown in figure 9, can be disassembled stainless steel feet head 308 when using base station mode operations,
It uses connection component outer tube 102 to connect with foot prop 401 in order to measure, is wanted so that transmitting antenna 501 be made to can satisfy antenna height
It asks.Further, for the ease of installing transmitting antenna 501,101 top of inner tube of measurement connection component has in the present embodiment
The thread docked with transmitting antenna 501.And stainless steel feet head 308 is caused to exist because often dismantling stainless steel feet head 308 in order to prevent
It is caducous when use to happen, it is also additionally arranged between 102 bottom end of outer tube and stainless steel feet head 308 in the present embodiment locking
Washer 309.
In order to improve the application range of measurement connection component, as a preferred embodiment, used in the present embodiment in measurement
101 outer wall of inner tube of connection component, which is provided with, can be used for measuring the scale of object length so that measurement with connection component not only
It can be used for specialized engineering measurement, as shown in figure 8, can be used for conventional length measurement, as shown in Figure 7.
And in order to reduce the weight of measurement connection component, to reduce the fatigue strength in user's use process, as one kind
Preferred embodiment sets 27mm for 102 outer diameter of outer tube of measurement connection component in the present embodiment, and 101 outer diameter of inner tube is set as
18.5mm, which can connect with external small-sized measuring device, to meet the needs of different crowd, with this
Simultaneously as 102 outer diameter of outer tube and 101 outer diameter of inner tube of measurement connection component are significantly less than centering rod currently on the market
Outer pipe outside diameter and inner tube outside diameter, therefore the measurement in the present embodiment is substantially reduced with connection component weight, to enhance user's body
It tests.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideas
Corresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present invention
Within.
