Embodiment
Below in conjunction with Figure of description, the present invention will be further described.
The surveyor's staff of available end surface measurement of the present invention is as shown in Fig. 1-5,6-9, it comprises that section bar chi body 01(section bar is as aluminium alloy extrusions), on section bar chi body 01, be equipped with and measure bubble 02, in the end endoporus of section bar chi body 01, assemble closeouts 03, the outer face of closeouts 03 is made as measurement face 31 for measuring at small space.
As a kind of version of assembling closeouts 03, be to establish locking structure 04 in the end endoporus of section bar chi body 01, closeouts 03 is inserted in the endoporus of section bar chi body 01 end and by locking structure 04 locking.
Concrete, locking structure 04 comprises that at least one end that can axial stretching is exposed at the lock pin 41 outside section bar chi body 01, on lock pin 41, is respectively equipped with lock part 45 and dodges portion's (radial dimension of lock part 45 is greater than the radial dimension of the portion of dodging) along its axial different parts; Closeouts 03 is provided with the clamping location division for coordinating with lock pin 41.Therefore, be exposed at the end outside section bar chi body 01 by operation (as pressing) lock pin 41, make lock pin 41 axial stretchings, make lock part 45 and clamping location division coordinate (referring to Fig. 5-9) to realize locking or make the portion that dodges and clamping location division corresponding (referring to Fig. 4) to change the mated condition of the relative section bar chi of closeouts body.
Further, on lock pin 41, effect has pair lock pin 41 to produce the elastic component 44 of axial elastic force, lock pin 41 is remained on the state that lock part 45 coordinates with clamping location division by the elastic force of elastic component 44, to keep the assembly relation of closeouts 03 and section bar chi body 01 under normality, the rear lock pin 41 of operation lock pin 41 can be at self-resetting.
More specifically, for simple in structure and be convenient to assembling, in the end endoporus of section bar chi body 01, be fixed with pedestal 42, lock pin 41 is assemblied on pedestal 42, elastic component 44 is supported between pedestal 42 and lock pin 41.
And in closeouts 03, effect has the flexible member 05 that it is outwards applied to elastic force, to dodging portion and clamping location division at once closeouts 03 outwards being ejected.Especially, closeouts 03 is provided with blind hole 32, pedestal 42 is provided with the reference column 43 of corresponding blind hole, flexible member 05 is spiral spring and its one end is nested with on reference column 43, its other end is supported on blind hole 32 bottom, can be to volute spring effective location, avoid the volute spring position of losing the job.And blind hole 32 is symmetrical two, thereby arrangement flexible member that can be symmetrical makes closeouts uniform stressed.
As a kind of version of clamping location division, referring to Fig. 1-5, it can be a pair of card 33, and card 33 is provided with and coordinates the draw-in groove (draw-in groove 35 shown in Figure 7) of realizing locking with lock part (referring to lock part 45 shown in Fig. 7, Fig. 9).Especially card 33 and the draw-in groove be located on each card are arranged symmetrically with, so that uniform stressed.The clamping location division of this structure, is convenient to dismounting and change closeouts.The clamping location division of this structure, in the time as shown in Figure 4 lock pin 41 being pressed, the portion that dodges of the corresponding lock pin of draw-in groove on card 33, thus closeouts 03 can be pulled down from the endoporus of section bar chi body 01, after release lock pin, lock pin is upspring as shown in Figure 3; Otherwise also can in the time pressing lock pin, load onto closeouts 03, now discharge lock pin after lock pin upspring as shown in Figure 5, the lock part of lock pin coordinates with the draw-in groove on card realizes locking to closeouts.
As a kind of version of clamping location division, referring to Fig. 6-9, clamping location division can be a slotted hole 34 being nested with on lock pin, the edge of slotted hole 34 is provided with and coordinates the draw-in groove 35 of realizing locking with lock part at least two places of its length direction, when the draw-in groove at one place coordinates with the lock part of lock pin 45, measure the end endoporus (referring to Fig. 8, Fig. 9) of face 31 indentation section bar chi bodies 01, when the draw-in groove at another place coordinates with the lock part of lock pin, measurement face stretches out the end endoporus (referring to Fig. 6, Fig. 7) of section bar chi body.The clamping location division of this structure, can be used for whole closeouts indentation chi bodies to deposit according to demand, also the measurement face of closeouts can be stretched out to chi body for measuring, and when indentation or the measurement face of stretching out, can operate lock pin as mode described in leading portion.
