Embodiment
In order to describe technology contents of the present utility model, construction feature in detail, below in conjunction with embodiment and coordinate accompanying drawing
It is described further.
Referring to Fig. 1, the interchangeable self-locking slide calliper rule 100 of measuring jaw of the present utility model include two exterior measuring measuring jaws 10, blade 20,
It is installed on the chi first 30 of the left end end of blade 20, is slidedly arranged on blade along the left and right directions (i.e. double-head arrow B is signified) of blade 20
Chi frame 40 and the interior survey that is respectively arranged at the top end of chi first 30 and chi frame 40 on 20 and at the right side of chi first 30
Measuring jaw 50.One exterior measuring measuring jaw 10 be close to along the left and right directions parallel to blade 20 at the left side wall of chi frame 40 and with by
Lock section 11 (see Fig. 3), another exterior measuring measuring jaw 10 is close to along the left and right directions parallel to blade 20 at the right side wall of chi first 30
And with by lock section 11, with cause external pelivimetry pawl 10 along the left and right directions group parallel to blade 20 in or be moved away from chi first 30 and chi
Frame 40, i.e. exterior measuring measuring jaw 10 at chi first 30 along the left and right directions group parallel to blade 20 in or be moved away from chi first 30, chi frame 40
The exterior measuring measuring jaw 10 at place along the left and right directions group parallel to blade 20 in or be moved away from chi frame 40.Chi first 30 and chi frame 40 are equipped with use
Carried out in the exterior measuring measuring jaw 10 to each locating by lock section 11 sealed to forbid exterior measuring measuring jaw 10 along the left and right parallel to blade 20
Direction unload from lock set 60.User's operation makes to allow exterior measuring measuring jaw 10 along the left and right parallel to blade 20 from lock set 60
Unload and realize exterior measuring measuring jaw 10 and change in direction.Specifically, as shown in Figures 3 and 4, in the present embodiment, the left side of chi frame 40
The right side wall of wall and chi first 30 respectively offers being stretched by lock section 11 for the exterior measuring measuring jaw 10 at self-locking movable chamber 70, chi first 30 and is placed in
In self-locking movable chamber 70 at the chi first 30, being stretched by lock section 11 for exterior measuring measuring jaw 10 at chi frame 40 is placed at the chi frame 40
In self-locking movable chamber 70, to provide space from 60 pairs of sealed and release the lock operations by lock section 11 of lock set, but it is not limited；Lift
For example, as shown in Figures 3 and 4, in the present embodiment, elastic component 61 is respectively included from lock set 60 at chi first 30 and chi frame 40
And self-locking block 62, above-below direction (i.e. in Fig. 1 double-head arrow C signified) of the self-locking block 62 along blade 20, which is slided, to be arranged so that self-locking block
62 can along blade 30 above-below direction slide so that meet self-locking block 62 it is sealed by lock section 11 or release by lock section 11 requirement；
Self-locking block 62 has and by the sealed main lock section 621 in lock section 11, elastic component 61 is permanent has and drives main lock section 621 along parallel to blade
20 above-below direction is slided to and by the sealed trend in lock section 11, to go to realize the main lock section 621 of self-locking block 62 by elastic component 61
With the purpose by the self-locking of lock section 11 of exterior measuring measuring jaw 10, so that self-locking is convenient and swift and simple in construction, but is not illustrated and be limited with this.
More specifically, as follows：
As shown in Figures 3 and 4, above-below direction of the main lock section 621 in same self-locking block 62 along blade 20 is in one on the other
Arrangement, same exterior measuring measuring jaw 10 by above-below direction of the lock section 11 along blade 20 in arranging one on the other, increase self-locking block 62
At cooperation with 10 self-lockings of exterior measuring measuring jaw, so improve the external measuring claw 10 of self-locking block 62 by sealed reliable in lock section 11
Property, but be not limited.Specifically, in the present embodiment, the elastic component 61 at chi first 30 is compression spring and is connected to chi head
30 and the chi first 30 on self-locking block 62 between, elastic component 61 at chi frame 40 is compression spring and is connected to chi frame 40 and the chi
Between self-locking block 62 on frame 40, the self-locking block 62 at chi first 30 is slidedly arranged on chi first 30, and the self-locking block 62 at chi frame 40 is slided and set
In on chi frame 40, to go to simplify the simple in construction of elastic component 61 by compression spring, the main lock of self-locking block 62 is also reliably driven
Portion 621 has the trend sealed by lock section 11 with exterior measuring measuring jaw 10, but is not limited.For example, as shown in figure 4, main
Lock section 621 and be respectively hook-like configuration by lock section 11, to simplify both structures and ensure the reliability of both self-lockings；And by lock section 11
With the inclined pushing tow inclined-plane 111 of above-below direction along blade 20, main lock section 621 has driven with the cooperation of pushing tow inclined-plane 111
Inclined-plane 6211, therefore exterior measuring measuring jaw 10 makes to be slided to and master by lock section 11 by pushing tow inclined-plane 111 to the pushing tow on driven inclined-plane 6211
The sealed position in lock section 621, therefore, exterior measuring measuring jaw 10 is assembled in along the left and right directions parallel to blade 20 left side of chi frame 40
During wall, mobile exterior measuring measuring jaw 10 makes self-locking block 62 overcome elasticity the pushing tow on driven inclined-plane 6211 by pushing tow inclined-plane 111
The elastic force of part 61 and to bottom offset so that exterior measuring measuring jaw 10 is opened main lock section 621 by the top of lock section 11 and slides to exterior measuring measuring jaw
10 positions being close to the left side wall of chi frame 40, then self-locking block 62 now is again under the elastic force of elastic component 61 so that self-locking block 62
Main lock section 621 with being locked together by lock section 11, realize the purpose of self-locking.Because exterior measuring measuring jaw 10 is assembled in the right side wall of chi first 30
On principle it is identical with the principle for the left side wall that exterior measuring measuring jaw 10 is assembled in chi frame 40, therefore will not be repeated here.
As shown in Figures 1 and 2, chi first 30 and chi frame 40 are each provided with the cover plate 80 at cover plate 80 and screw 90, chi first 30
The screw 90 at the elastic component 61 and self-locking block 62 at the chi first 30, chi first 30 is covered to be fixed in the cover plate 80 at the chi first 30
On chi first 30, the cover plate 80 at chi frame 40 covers the screw 90 at the elastic component 61 and self-locking block 62 at the chi frame 40, chi frame 40
Cover plate 80 at the chi frame 40 is fixed on chi frame 40.
Compared with prior art, because an exterior measuring measuring jaw 10 in the utility model is along the left and right parallel to blade 20
Direction is close at the left side wall of chi frame 40 and with by lock section 11, and another exterior measuring measuring jaw 10 is along the left and right parallel to blade 20
Direction is close at the right side wall of chi first 30 and with by lock section 11, and chi first 30 and chi frame 40 are equipped with for each locating
Exterior measuring measuring jaw 10 carried out by lock section 11 it is sealed with forbid exterior measuring measuring jaw 10 along the left and right directions parallel to blade 20 unload from
Lock set 60, operation makes to allow exterior measuring measuring jaw 10 to unload along the left and right directions parallel to blade 20 from lock set 60, so as to realize
Exterior measuring measuring jaw 10 is changed, so that the replacement operation of exterior measuring measuring jaw 10 is very convenient and swift；Meanwhile, in the absence of because of stripped thread
The defect for causing exterior measuring measuring jaw 10 not change, so that it is guaranteed that the reliability that exterior measuring measuring jaw 10 is changed.
Above disclosed is only preferred embodiments of the present utility model, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to the utility model claim still fall within the model that the utility model is covered
Enclose.
