Abstract

The utility model discloses a rod regulating positioner which can be used on various machines, household appliances, furniture and life and cultural articles. A pipe sleeve 1 and a rod core 2 are residual parts of a cylinder hole and a cylinder body which are separately cut 1 to 4 parts by a flat surface or a curved surface which are parallel to the shaft lines of the cylinder hole and the cylinder body. An inner groove 6 and an outer tooth 5 are arranged on the residual inner and outer cylinder surfaces of the pipe sleeve 1 and the rod core, and the outer tooth 5 can be screwed inside the inner groove 6. When the residual part of the rod core 2 is aligned to the cut part of the pipe sleeve 1, the rod core 2 can be inserted into the pipe sleeve 1 to slide axially; when the rod core 2 rotates at a certain angle relative to the pipe sleeve, the axially relative position between the rod core and the pipe sleeve is locked.

Description

Rod member is regulated positioning work piece

The utility model relates to a kind of rod member and regulates positioning device.

On various machineries, household electrical appliances, furniture, daily necessities, using rod member to regulate positioning device widely, in order to regulating the relative position between other parts, length, just, and as: tripod for camera, medical infusion aircraft etc.In the prior art, realize above-mentioned levelling method commonly used a kind of be to open several grooves vertically at pipe socket, outside it on cylinder of garden, be shaped on the garden tapered thread, and the nut of the figure of a being shaped on tapered thread with matching arranged, rely on tightening nuts during use, the pipe socket internal diameter is shunk and the bar core is clamped.Another kind is laterally to bore an aperture at pipe socket, is shaped on screw thread in the hole, is screwed into a screw in the screw thread, is commonly called as " jackscrew ", and the bar core dieback that relies on screw will insert pipe box is fixed.The shortcoming one of above-mentioned two kinds of methods is troublesome poerations, comparatively requires great effort when unclamping with tightening nuts and screw, and will rotate several circles; The 2nd, poor reliability, sometimes because the distortion of other part, it is still clamped that garden awl nut unclamps back bar core, or garden awl nut wants that core is still fixing not to be lived after tightening, or lost efficacy because of the screw stripped thread.

The new purpose of this practicality provides a kind of swift to operate, convenient, the reliable rod member adjusting in adjusting location positioning device.

The utility model rod member is regulated positioning work piece and is made up of bar core and pipe box.The bar core is that a Cylinder is cut the remaining part in 1～4 part back with plane that is parallel to its axis or curved surface.Outside the bar core is remaining, on the cylinder of garden, be shaped on outer tooth.Pipe box can regard that the garden pipe that an internal diameter is equaled the outer root of the tooth garden of bar core diameter correspondingly cuts out 1～4 remaining part in back partly as, and its part that cuts out should guarantee that the bar core just inserts wherein and can freely slide vertically.Be shaped on inside groove on the cylinder of garden in pipe box is remaining, the thread form of inside groove, tooth distance are identical with outer tooth, and the internal diameter of inside groove and external diameter and outer tooth cooperatively interact, and guarantee that outer tooth can screw in the inside groove.

In order to find " levelling " and " locking " position quickly and accurately, and can keep lock state after locking, the not end at the inside groove camber line of pipe box is shaped on pin-and-hole, inserts a locating stud in pin-and-hole.

Technique scheme, the part alignment tube of tooth puts when cutting out partly outside being shaped on the bar core, and the bar core can insert pipe box and can freedom move vertically in pipe box.When the bar core moves to the position that needs, only need 25 °～90 ° of bar core or pipe box rotations, in the inside groove that the outer tooth spinning in pipe on the bar core is put, can the limit rod core and pipe box between axially relative displacement, it is very convenient quick therefore to operate.On the other hand, it is not a frictionally, but the axial thrust power on outer tooth and the inside groove shoulder realizes axially locating, thereby its reliable operation.

The utility model is further described below in conjunction with drawings and Examples:

Fig. 1 is the erection drawing of bar core and pipe box;

Fig. 2 and Fig. 3 are respectively the structural drawing of bar core and pipe box;

Fig. 4 and Fig. 5 are the erection drawings of different cross section shape bar core and pipe box.

In Fig. 1, Fig. 2 and Fig. 3, rod member is regulated positioning work piece by bar core 2, and pipe box 1 and locating stud 4 are formed.Bar core 2 is that Cylinder is cut two remaining parts in back partly with the plane symmetry ground that is parallel to its axis, on the cylinder of the outer garden of bar core 2, tooth 5 outside the triangle is arranged.Pipe box 1 can regard that the garden pipe that an internal diameter is equaled the 5 garden diameters of outer tooth on the bar core 2 correspondingly cuts out remaining part behind two sections arcuate zones as.Bar core 2 can insert and cut out position and can sliding vertically therein on the pipe box 1, is shaped on leg-of-mutton inside groove 6 on the post surface, interior garden of pipe box 1, and the tooth distance of inside groove 6 is equal with outer tooth 5.Their external diameter, internal diameter cooperatively interacts, and guarantees that outer tooth 5 can screw in the inside groove 6.

Swingle core 2 or pipe box 1 during use make the part that outer tooth is arranged on the bar core 2 aim at cutting out partly on the pipe box 1, and bar core 2 can move vertically at this moment; Mechanism is in " levelling " state; Shown in a among Fig. 1, when aligning, only need bar core 2 or pipe box 1 half-twist to desired location; This moment, outer tooth 5 promptly screwed in the inside groove 6, and bar core 2 is fixed with the relative axial position of pipe box 1, and mechanism is in " locking " state, shown in b among Fig. 1; Regulating location work finishes.

In order to find " levelling " and " locking " position quickly and accurately, and can keep lock state after locking, the not end at the camber line of inside groove 6 is shaped on a pin breast 3, wherein inserts locating stud 4.When bar core 2 is rotated counterclockwise when the pin 4 that is positioned blocks, it promptly is in " levelling " position; When 2 dextrorotations of bar core go to the pin 4 that is positioned when blocking, it promptly is in " locking " position.

Among Fig. 4, bar core 2 and pipe box 1 are respectively that the garden cylinder that is parallel to its axis cuts the remaining part in two part backs, and the outer outline of bar core 2 and the interior profile of pipe box 1 overlap fully.A is the levelling phase diagram, and b is lock state figure.

Among Fig. 5, bar core 2 is that a Cylinder is mutually three planes of 60 jiaos and cuts three remaining parts in back partly.A is the levelling state, and b is a lock state.

Thread form of the present utility model also can adopt rectangle, trapezoidal, semicircle, zigzag fashion etc., and inside groove 6 and outer tooth 5 can be made independent groove and tooth, also can be made into the pattern of internal and external screw thread, and all these variations all belong to protection domain of the present utility model.
