Abstract

The utility model relates to a pin joint member bar structure, which is composed of two member bars, a pin joint shaft, steel balls, elastic elements and adjusting screws. A member bar is provided with a notch in which the other member bar can be inserted, and the two member bars are pin jointed by the pin joint shaft. The utility model is characterized in that the two side surfaces of the two member bars are provided with a plurality of screw holes and semicircular pits each two among which are corresponding and each two inner rings and outer rings are staggered. The steel balls, the elastic elements and the adjusting screws are assembled by the screw holes. The steel balls can be just containd in the semicircular pits. The two member bars have proper tightness and can be optionally positioned. The utility model is a pin joint member rod with precise positioning angle and adjustable tightness.

Description

Driving-join rod structure

The utility model relates to a kind of pivot joint member structure, refer in particular to a kind of have can adjust the pivot joint member structure that pivot closes elasticity and has multiple orientation angle.

Being articulated in our daily life everywhere as seen of rod member especially can arbitrarily be adjusted the article of rod member angle, as the motor of desk lamp joint or fan and supporting base engagement angles etc.; And the design of the pivot-connecting position of these class article all has a quite main designing requirement, promptly must adjust the pivot joint angle easily at any time, and can locate at any time and can not drop; But it is well-known, when we when using this class desk lamp or fan, often run into an insoluble puzzlement, that is to use in the near future, these pivot-connecting positions just can be difficult for the puzzlement of location at any time because of abrasion produces, even revolve its pivot button tight again, two hands are just decontroled, desk lamp that articulates or fan motor are at once sagging with it, allow the Consumer regret in vain and can't solve its puzzlement.

The purpose of this utility model is to overcome the above-mentioned defective of prior art and a kind of pivot joint member structure is provided.

Be a kind of pivot joint member structure of realizing that the purpose of this utility model proposes, it is caused by two rod members, drive-connecting shaft, steel ball, elastic element and the combination of adjustment screw; One rod member has recess and just can insert and utilize drive-connecting shaft that it is articulated combination for another rod member; It is characterized in that: the bi-side of two rod members are provided with two corresponding and many screws that inner and outer rings two two positions stagger and semicircle holes, utilize the screw group to establish steel ball, elastic element and adjustment screw, steel ball just can hold and is placed in the semicircle hole, make two rod members have suitable elasticity and can arbitrarily locate, become the pivot joint rod member that a kind of orientation angle is fine and closely woven and the tool degree of tightness is adjusted.

The utlity model has multiple advantages from the above, as:

1. the rod member two sides of Shu Jieing all has steel ball to hold for the location, and surface of contact is big and stressed even, and two rod members can keep good pivot joint assembled state.

2. the steel ball that elasticity is engaged, elastic element, adjustment screw and semicircle are cheated, screw is with inside and outside ring and be the corresponding in twos mode setting of staggering, its angle of doing at any time to locate can be finer and closely woven cutting apart, that is can remedy the puzzlement that adjacent two positions can't be located by this mode.

3. bi-side make 360 ° of equally spaced positions, no matter are to be used for pivot that bendable is converted into two rod members of the vertical (as shown in Figure 3) that merging phase (as shown in Figure 2) maybe can't merge to set up jointly and connect all quite suitablely, and it has wide range of applications.

4. have outside the steel ball elastic positioning of both sides, adjust screw can supply easily because of use with the passing of time abrasion and the adjustment at any time of elasticity, simple and easy clear and definite, quite have practicability.

For technological means and the creation characteristic that the utility model is used is easy to understand, conjunction with figs. and figure number are described in detail as follows now:

Fig. 1 is a cross-sectional schematic of the present utility model;

Fig. 2 is combination of the present utility model and rod member action schematic representation;

Fig. 3 is another combination of the utility model and rod member action schematic representation;

At first, see also shown in whole accompanying drawings, the utility model mainly is by two

rod members

1,2 and drive-connecting shaft 3, steel ball 4, elastic element 5, adjusts elements combination such as screw 6 and form.

There is a suitable recess 11 just can insert in the rod member 1 for another rod member 2, and utilize drive-connecting shaft 3 fasteners 31 to articulate combination two rod members 1,2: wherein rod member 1 both sides are provided with many screws 12, and 12 one-tenth two donuts of screw around and the setting that is equally spaced, and the also corresponding with it many semicircles hole 21 that is provided with, another rod member 2 bi-side, just can hold, and this sodium pearl 4 is subjected to holding by adjusting screw 6 of elastic element 5 to adjust its elasticity for the steel ball 4 that passes screw 12.

Utilize above-mentioned combination to cause, arbitrarily pull a

rod member

1 or 2, steel ball 4 is promptly beated on half and half round pool 21, when stopping to pull, then locatees motionless immediately; Because the semicircle of inside and outside ring hole 21 and screw 12 are the corresponding mode setting of staggering, promptly the position of outer shroud at interior ring between any two; Otherwise the position of interior ring and is equipped with steel ball 4, elastic element 5 and adjusts screw 6 also at outer shroud between any two in each screw 12, makes each semicircle hole 21 all can be for inserting to locate the pivot joint angle of two

rod members

1,2 holding of steel ball 4.

Claims

1, a kind of pivot joint member structure, it is caused by two rod members, drive-connecting shaft, steel ball, elastic element and the combination of adjustment screw; One rod member has recess and just can insert and utilize drive-connecting shaft that it is articulated combination for another rod member; It is characterized in that: the bi-side of two rod members are provided with two corresponding and many screws that inner and outer rings two two positions stagger and semicircle holes, utilize the screw group to establish steel ball, elastic element and adjustment screw, steel ball just can hold and is placed in the semicircle hole, make two rod members have suitable elasticity and can arbitrarily locate, become the pivot joint rod member that a kind of orientation angle is fine and closely woven and the tool degree of tightness is adjusted.
