Abstract
The utility model relates to a rack rod joint connector which is provided with a cylindrical body which can be screwed with a sheep eye socket and a circular cap thread hole at the middle part, and the utility model is provided with at least three open slots which extend towards the outer edge of the end surface of the cylindrical body according to different orientations and angles and can be connected with a rack rod along the radical direction, wherein each open slot is a U-shaped counterbore slot with small inner part and big outer part; a through hole extending towards the rear end face of the cylindrical body is arranged on a small end corresponding to a slot opening of the U-shaped counterbore slot; the diameter of the through hole is smaller than the diameter of a ball of a joint head of a connecting rod member. The utility model with light weight, flexibility and portability solves the problem of a cylindrical sleeve for splicing the rack rod in the prior art. Matching with a spherical joint rod with universal change, the utility model can rotate towards different directions to be positioned so as to regulate the degree of freedom, and thus, the spherical joint can rotate up and down and right and left. An assembled joint support can be changed into support bodies with different shapes such as a rectangle, a square, etc. The utility model is especially suitable for connecting the support rods of a tent and a supporter of a fixed instrument of the field operation.
Description
Technical field
The utility model relates to a kind of each joint connector to connection support rod member.The joint connector that the utility model relates in describing is to connect the joint connection that rod member is an object.It can connect the supporting rod of tent, also can connect the tripod of field work retainer instrument, can also be fit to other connections such as billboard supporting rod joint.
Background technique:
Support joint connector in the known technology is that the support rod member directly is inserted in the cylindrical sleeves hole of being fixed in joint coupling shaft end face slotted eye, and the cylindrical sleeves of its door assembly with hinge and glass in right hand and left axle is movably connected in the rotary axis groove of this assembly axis end face slotted eye.Profile is radial groove do 0～90 degree rotation stretching, extension that polygonal cylindrical sleeves can only be left along four right angles, its circular hole plane, can not oscillation adjustment, only can connect foursquare frame rod member, the orientation that connects is very limited, thereby using scope is narrow, the variation of geometrical shape like a fish out of water.Concerning the support that is connected, have only a rotational freedom that rotates along its vertical plane, be fixed as a shape only.After rod member connects, can not realize the adjusting of mobile or rotational freedom to other directions.Because it directly connects as one cylindrical sleeves with the joint coupling shaft, make its figure comparatively heaviness that becomes, use dumb, also inconvenience.
Summary of the invention
The utility model provides a kind of light and flexible at the defective that exists in the prior art, to connecting the joint connector that rod member has two rotational freedoms at least.
The technological scheme that realizes the utility model purpose is: a kind of support rod member joint connector, have a middle part and be shaped on the cylindrical body of can be spirally connected screw eye and dome tapped hole, it is shaped at least three opening slots that can connect the support rod member by the different azimuth angle to the extension of cylindrical body end face outer rim diametrically, it is characterized in that: described opening slot is inner small and outside big U-shaped counterbore groove, the small end of corresponding U-shaped counterbore groove notch also is shaped on the through hole that leads to the cylindrical body ear end face, and the diameter of this through hole is less than connecting rod member ball and socket joint sphere diameter.
U-shaped counterbore groove described in the utility model can be the counterbore opening slot of asymmetric U-shaped center line, and promptly the length on inclined-plane, one side is greater than the chamfer length of another side, as shape J-shaped U word hook.
Dome described in the utility model can be a spheroid cross-sectional shape structure.
End face joint one end of connection rod member described in the utility model is shaped on spherosome.
The utility model compared with prior art has following beneficial effect.
Than prior art, the utility model has not only saved the burden of the cylindrical sleeves of grafting support rod member, light and flexible, and cooperate spherical joint rod member with universal variation connection, realized the location adjusting degrees of freedom of multi-direction rotation, its spheroidal joint is rotated up and down.The knuckle support that installs can be transformed to difform stake body, as rectangular, and square etc.Aspect processing, owing to do not flexibly connect the hinge structure of cylindrical sleeves, thereby easy to process, cost reduces, weight saving, it is perfect that outward appearance more becomes.
Following accompanying drawing has been described an embodiment of the present utility model.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the rear view of Fig. 1.
Fig. 3 is the utility model and schematic representation after the support rod member is connected.
Embodiment
Fig. 1, Fig. 2 have described the joint connector cylinder body of being made by engineering plastics or metallic material 2, and its middle part is shaped on the tapped hole 1 of be spirally connected Fig. 3 screw eye hole 8 and dome (not shown).It directly upwards can be shaped on four uniform several angles of each interval as shown in Figure 1, and the opening slot 3 that extends to cylindrical body end face outer rim, and this opening slot 3 can be inner small and outside big U-shaped counterbore groove.Described U-shaped counterbore groove can be the counterbore opening slot of asymmetric U-shaped center line.The length on its inclined-plane, one side can be the chamfer length greater than another side, with J-shaped U word hook as shape.The location counterbore groove of making by required support on the circumference among the figure can go out by the irregular numeral system of not limitting, and also can be made into shapes such as blade profile groove, and opening can not limit the 45-90 degree number of degrees.The knuckle support that installs can be transformed to the stake body of different geometries like this, as rectangular, square etc.Small end at corresponding U-shaped counterbore groove notch also is shaped on the through hole 4 that leads to cylindrical body ear end face 5, and the diameter of this through hole 4 is usually less than connecting rod member ball and socket joint sphere diameter.Ear end face 5 can be a plane, also can be spherical.
Among Fig. 3, connect support rod member 7 end face joints one end and be shaped on spherosome 6.Connecting rod member 7 can be fiber rod, also can be metal rod.The big end of the joint spherosome 6 that connects support rod member 7 by U-shaped counterbore groove snaps in the small end notch and links to each other with the through hole 4 of cylindrical body ear end face 5, makes joint spherosome 6 acquisition rotational freedoms, makes it and can rotate up and down.Be spirally connected then and go up screw eye, the dome that will be the spheroid cross-sectional shape again is by the screwed hole of centre 1 of screw in cylindrical body back side end face 5.
