Abstract
The utility model relates to a quick clamping apparatus, which is characterized in that one end of a pin shaft (3) fixed on a lower connecting plate (2) is provided with a flat positioning platform which fits to a positioning hole arranged on the side face of an upper connecting plate (1). The utility model provides a locking device which has the advantages of convenient operation, one time operation of fixation or loose, and double insurance.
Description
The utility model relates to connection, the locking device of two sections rod members.
General foldable poles be two sections bars or pipe fitting end each fix a connecting plate, a side of two connecting plates is hinged, side has a Camlock device in addition.When locking state, bearing pin is through in the hole of lower connecting plate, and its end has a location cylindrical to adapt with the locating hole of upper junction plate side.The Camlock pull bar vertically passes the hole at bearing pin middle part, and by adjusting the size that nut goes to adjust coupling mechanism force, eccentric handle rotates around the axis, and realizes unclamping or locking.At locking state, the eccentric handle that counterclockwise rotates around the axis around the bearing pin swing, is deviate from upper junction plate then, and this moment, Camlock mechanism unclamped.The pad axle makes the spring compression again, and bearing pin moves axially, and makes the end axle journal align upper junction plate locating hole lower openings.This moment, upper and lower connecting plate can rotate around the hinge of opposite side, realized the folding of two rod members.Said apparatus all needs two actions in the process of unclamping and clamping, and must push down bearing pin, upper and lower connecting plate is unclamped and locks, so operation inconvenience.
The purpose of this utility model provides a kind of easy to operate, can disposable operation fixes or unclamp and have the locking device of double insurance.
Technical solution of the present utility model is such, at the connection of existing two sections rod members, the upper junction plate of locking device, lower connecting plate, the Camlock pull bar, adjust nut, rotating shaft, on the basis of eccentric handle, the utility model particularly has a flat locating platform that adapts with upper junction plate side locating hole at an end that is fixed on the bearing pin on the lower connecting plate.
The outer wall of the outer face of the locating platform of above-described flat and upper and lower connecting plate the same side is in same plane.
The flat locating platform of one end of the utility model bearing pin can be that the center line of its flat locating platform overlaps with the shaft centre line of bearing pin, and the both sides of the opening part of locating hole bottom, upper junction plate side are symmetry and two parallel straight flanges.
The rotating shaft core of above the utility model eccentric handle to the bearing pin distance of shaft centers from the distance c of the eccentric throw b of a and eccentric handle sum more than or equal to the bearing pin axis in same vertical plane to upper junction plate end face front, i.e. a+b 〉=c.
The flat locating platform of one end of the utility model bearing pin, the center line that yet can be its flat locating platform does not overlap with the shaft centre line of bearing pin, just the flat locating platform is asymmetric in bearing pin shaft centre line two side portions, for adapting with it, the opening part of locating hole bottom, upper junction plate side, one straight line on one side of its opening part also extends to the tangent line that becomes circle on the locating hole circumference, and this limit and opening part opposite side are that the former is less than the latter to distance between center line.
The utility model has the advantages that and can disposable operation fix or unclamp, and the locking device of double insurance is arranged.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1 organigram of the present utility model;
The flat locating platform structure of Fig. 2 bearing pin of the present utility model and the working state schematic representation that locking device unclamps;
The asymmetric flat locating platform structure of the bearing pin of Fig. 3 application examples of the present utility model, and locating hole lower openings place, upper junction plate side organigram;
Fig. 4 bearing pin of the present utility model termination locating platform structure and position view.
Shown in Fig. 1,2,3,4, the utility model is at the upper junction plate 1 of the connection locking device of existing two sections rod members, lower connecting plate 2, Camlock pull bar 4, adjust nut 5, rotating shaft 6 is on the basis of Camlock handle 7, the utility model is at an end that is fixed on the bearing pin 3 on the lower connecting plate 2 a flat locating platform that adapts with upper junction plate 1 side locating hole to be arranged, and the outer wall of the outer face of the locating platform of flat and upper junction plate 1 the same side is in same plane.The rotating shaft b axle center of eccentric handle 7 to bearing pin 3 distances of shaft centers from the eccentric throw b sum of a and eccentric handle 7 distance c, i.e. a+b 〉=c more than or equal to 3 axis of the bearing pin in same vertical plane to upper junction plate 1 end face front.
Before upper and lower connecting plate of the present utility model closed up, the flat locating platform of bearing pin 3 ends aligned the opening of locating hole bottom, upper junction plate 1 side.After the flat locating platform inserted opening, swing Camlock pull bar 4 made the locking pull bar snap in upper junction plate 1, rotates the Camlock handle again, can realize the disposable operation fixing and locking of upper and lower connecting plate, as shown in Figure 1.This moment bearing pin 3 ends the position of flat locating platform, as Fig. 2, in the upper junction plate lateral aperture shown in the double dot dash line, when this programme unclamps in Camlock mechanism, locking pull bar 4 rotates in the scopes of diagram less than 90 degree, and upper and lower connecting plate also can be in connection status because of the flat locating platform of bearing pin 3 ends and the interference of upper junction plate lateral aperture.Realize the locking of double insurance.And when 3 rotations 90 of locking pull bar 4 drive bearing pins are spent, because of the center line of flat locating platform overlaps with the shaft centre line of bearing pin 3, and the both sides of the opening part of locating hole bottom, upper junction plate 1 side are symmetry and two parallel straight flanges, therefore the flat locating platform just can be realized coming out from upper junction plate 1 side locating hole lower openings slippage easily, that is to say to have realized that disposable operation unclamps.Can rotate upper and lower connecting plate this moment very easily, realizes the folding of rod member.Because of the flat locating platform in bearing pin axial line both sides symmetry, so one 90 of revolution degree all can skid off, be exactly that two symmetrical limits all can skid off like this.
The locating platform of bearing pin 3 of the present utility model also can be that the center line of its flat locating platform does not overlap with the shaft centre line of bearing pin, just the flat locating platform is asymmetric in bearing pin shaft centre line two side portions, for adapting with it, the opening part of locating hole bottom, upper junction plate 1 side, one side of its opening part is a straight line and extends to the tangent line that becomes circle on the locating hole circumference, as Fig. 3.During this kind shape, locking pull bar 4 moves in illustrating less than the scopes of 180 degree, upper and lower connecting plate also can be in connection status because of the flat locating platform of bearing pin 3 ends and the interference of upper junction plate 1 lateral aperture, thereby improved the security that upper and lower connecting plate connects, realized the locking of double insurance.In this case, asymmetric because of the flat locating platform in bearing pin shaft centre line two side portions, therefore can only revolve 180 degree from a fixed-direction, could skid off from upper junction plate 1 side locating hole opening.
The condition that the utility model can be realized is: a+b 〉=c.
