Abstract
The utility model relates to a quick fastening spanner for a tripod, which comprises a pair of press plates capable of clamping two fixing rods of a tripod support leg, wherein a draw rod is penetrated between the two press plates, one end of the draw rod is provided with a limited blocking head and the other end of the draw rod is hinged with a cam with a handle. When the cam handle is rotated, the press plates are tightly butted by the cam and are fixed to a support frame. The utility model has the advantages of convenient operation and easy fastening and release, and avoids the phenomenon that fingernails are damaged by that the fastening spanner can not be successfully lifted when the original and old type tripod spanner is released after the fastening.
Description
Technical field
The utility model relates to the regulating mechanism of surveying instrument tripod, and particularly a kind of tripod is locked spanner fast.
Background technique
The quick locking mechanism of traditional tripod all is to adopt spiral to tighten mode, this mode operate cumbersome and efficient low.For the ease of adjusting, the quick locking mechanism of the tripod of developed country is modified into the quick locking mechanism of presser type mostly in the world.Used quick locking mechanism is the product of the imitative U.S. on the Chinese market at present, after shortcoming is the locking of tripod spanner, is difficult to the people for unclamping, and is difficult for carrying out rapidly position adjustment next time.
Summary of the invention
The purpose of this utility model is the above-mentioned difficulties that will overcome prior art, for the surveying instrument tripod provides a kind of improved regulating mechanism, makes it convenient, quick and laborsaving.
Solution of the present utility model comprises a pair of pressing plate that can clamp tripod supporting leg two fixing rods, is installed with pull bar between two pressing plates, and an end of pull bar has the limiting block head, and the cam of the other end and a band handle is hinged.When the rotating cam handle, cam promptly pushes against pressing plate and makes it to be fixed on the support.
It can be a nut that above-mentioned limit is drawn the retaining head, is connected with pull rod screw.
The hinged end of above-mentioned pull bar and cam can be pressed into flat, and the hole that pull bar passes pressing plate also should be a long and narrow hole mutually.
Above-mentioned band handle cam can be working of plastics or metalwork, and is hinged by bearing pin and pull bar.
The advantage that tripod after the improvement is locked spanner fast is:
1. operation is convenient especially, locking and discharge all easy, when having avoided original old-fashioned tripod spanner after locking, to discharge because can't smooth cocked locking spanner, to such an extent as to damage finger nail.
2. the width that new tripod is locked spanner fast than old-fashioned width increased by three/
One, it is increased with the area of contact of locking pressure plate after locking, pressure reduces, frictional force reduces, thereby has prolonged the life-span of locking spanner, has reduced the main after sales service work of tripod, so both obtain user's welcome, saved the spending of maintenance expenses again.
Description of drawings
Fig. 1 is the plan view of quick locking mechanism.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Referring to accompanying drawing, tripod props up to move back by fixing rod 9,10 and sliding bar 5 etc. to be formed.During use, the pull bar 8 of this locking mechanism passes in the hole of sliding bar 5, is connected with sliding bar, can move with sliding bar.Pressing plate was in to prop up and moves back both sides in 4,6 minutes.One end of pull bar 8 has the nut 7 that blocks compressing tablet 6, and the other end of pull bar 8 is hinged with the cam 1 of strap wrenches by bearing pin 2.The limiting block head of pull bar 8 ends also can be other similar convex parts except that adopting nut.
When pulling to solid line position by dotted line position spanner 3,, so can push against two compressing tablets, make it to be fixed on two fixing rods, thereby finish quick locking because the eccentric curve diameter of cam increases gradually.When cam 1 was in locked position, its planar section and pressing plate 10 were fitted, and the angle of handle and sliding bar is 30 °, helped finger insertion plate and rose.Upwards pulled about 90 ° then pressing plate be in the state that gets loose fully.For ease of wearing bearing pin and making handle and the definite orientation of pressing plate maintenance, pull bar 8 is pressed into flat with the hinged end of cam, and the hole that pull bar passes pressing plate also should be a long and narrow hole mutually.
Claims (4)
1, tripod is locked spanner fast, comprise a pair of pressing plate (4,6) that can clamp tripod supporting leg two fixing rods, it is characterized in that: be installed with pull bar (8) between two pressing plates (4,6), an end of pull bar has the limiting block head, and the cam (1) of the other end and a band handle is hinged.
