Abstract

The utility model relates to a joint element structure, which is composed of two joint heads with shapes of mirror symmetry, and the two joint heads are provided with a circular wheel-shaped portion, a socket cylinder which is connected and arranged on the rear end of the circular wheel-shaped portion, a protruding ring portion which is arranged in the center of the external periphery of the socket cylinder, and a butted portion which is arranged on the top of the socket cylinder. The two joint heads can be combined into eccentric combined shapes with rivets, and through clamping nails which pass through fisheye holes of the two joint heads, the two joint heads can be fastened. When the joint element structure is used, the socket cylinder is inserted to an object which needs to be connected, and the two connecting objects can form a straightening state or a bending state.

Description

The joint component structure

The utility model relates to a kind of field that needs the folding rod member, particularly a kind of joint component structure.

Convenient and efficient are all stressed in current all aspects of living in, but the situation that large-sized object is set as the folding shape is very general, the camp of picture camping usefulness, because of portion within it accommodates more than the people, so volume was very big when it launched, use more comfortable, but just inconvenience to some extent when carrying, therefore the specification that the camp folding that the type body is very big in the time of how will opening becomes to be easy to carry about with one, for example how become shorter shape to be convenient for carrying the microscler pole folding of camp, can be fixed again when using and set up is steady status, just becomes an important problem.

And the common ball and socket structures that a stock folding become two to three joints, mostly be at two body of rod adjacent end portions screw is set, to screw togather a bolt again after the alignment of two body of rod screws, make two bodies of rod connect into a stock body, this kind method must lock instruments such as alignment of body of rod screw and palpus use screwdriver with bolt, instrument that so operation is more time-consuming and need be extra, if when but camp brought to the remote mountains and leaves behind instrument, then will cause the situation of making a futile effort, therefore how to develop a kind of must other aids operations to make body of rod joint component bent and locking be an important topic.

The purpose of this utility model is to overcome the shortcoming that above-mentioned technology exists, and a kind of joint component structure is provided.

For achieving the above object, the technical solution of the utility model is:

The joint component structure is made of two ball and socket joints that are shaped as the mirror image symmetry, two ball and socket joints have Round Wheel portion and are arranged in the jack tube of Round Wheel portion rear end and are located near the prominent ring portion the Round Wheel portion outer peripheral edges center and are located at the annular caulking groove that the prominent ring portion of confession on jack tube top embeds, wherein be respectively equipped with the rivet hole at stray circle colyliform portion center on two ball and socket joints, and both are combined into eccentric in conjunction with shape with rivet, two ball and socket joints go up and are provided with fish eyelet respectively in the relative position place simultaneously, the hole, big footpath of these two fish eyelets is the medial surfaces when being located at two ball and socket joints and combining, wherein the hole, big footpath of a fish eyelet has little teat, two blockings nail is the path hole of passing fish eyelet with its pole portion, and its enlarged head is supported in the hole, big footpath of fish eyelet, and can not deviate from from its path hole, when two ball and socket joints are bent into when making two fish eyelets relative, expose outside blocking nail pole portion end from fish eyelet path hole by pushing, the enlarged head that blocking is followed closely slips over little teat in hole, the big footpath of another fish eyelet, end stationary state and form card, this moment is if another outside blocking nail pole portion end is exposed in the path hole of another fish eyelet of pushing, then can make last blocking nail enlarged head deviate from little teat, make two ball and socket joints recover to change the state of bending angle.

Below in conjunction with description of drawings embodiment of the present utility model:

Symbol description:

10,10 ' is ball and socket joint, 11,11 ' is the jack tube, and 12,12 ' is Round Wheel portion, and 121,121 ' is fish eyelet, 121 " be little teat; 122,122 ' is rivet hole, 13,13 ' is prominent ring portion, and 14,14 ' is abutting part; 141,141 ' is annular caulking groove; the 15th, rivet, the 16, the 17th, blocking nail, the 161, the 171st, enlarged head.

As shown in Figures 1 to 4, the joint component structure of this novel preferred embodiment, it is the ball and socket joint 10 that is shaped as the mirror image symmetry by two, 10 ' constitute, two ball and socket joints 10,10 ' has Round Wheel portion 12,12 ' and be arranged in Round Wheel portion 12, the jack tube 11 of 12 ' rear end, 11 ' and be located at Round Wheel portion 12, near 12 ' the outer peripheral edges centers prominent ring portion 13,13 ' and be located at jack tube 11, the abutting part 14 on 11 ' top, 14 ', this abutting part 14,14 ' be provided with can be for prominent ring portion 13,13 ' the annular caulking groove 141 that embeds, 141 ', two ball and socket joints 10 wherein, be respectively equipped with the rivet hole 122 at stray circle colyliform portion center on 10 ', 122 ', both are combined into eccentric with rivet 15 in conjunction with shape, as shown in Figure 2, two ball and socket joints 10,10 ' goes up the relative position place is provided with fish eyelet 121 respectively, 121 ', fish eyelet 121, two ball and socket joints 10 are located in 121 ' hole, big footpath (not label), 10 ' medial surface when combining, wherein the hole, big footpath of fish eyelet 121 has little teat 121 "; as shown in Figure 3, two blockings nail 16; the 17th passes fish eyelet 121 with its pole portion; 121 ' path hole makes its enlarged head 161; 171 are supported in fish eyelet 121; in 121 ' the hole, big footpath and can not deviate from from its path hole (not label).

With two ball and socket joints 10,10 ' is bent into and makes two fish eyelets 121,121 ' relatively the time, pushing is exposed outside blocking and is followed closely 17 pole portion ends from the path hole of fish eyelet 121 ', can make the enlarged head 171 of blocking nail 17 slip over little teat 121 in the hole, big footpath of another fish eyelet 121 "; form card and end stationary state; as shown in Figure 4; follow closely 16 pole portion ends if outside blocking is exposed in the path hole of pushing fish eyelet 121 this moment; then can push by enlarged head 161 make blocking follow closely 17 enlarged head 171 to deviate from little teat 121 ", make two ball and socket joints 10,10 ' recovers to change the state of bending angle.In use, jack tube 11,11 ' inserts the body of rod that needs connection respectively, utilizes this joint component structure, and can make it to be in line connection and card end or folding state, utilize the different designs of two fish eyelets, also can make it to be fixed into arbitrarily angled.

According to this novel joint component structure, the joint component structure directly can be located at two body of rod two abutting end portions to be connect, so must not carry other aids relatively saves trouble, and its locking only can realize by the pole portion end of pushing blocking nail body with release, easy to operate and easy, and its clamping structure is firm, for example can form camp etc. effectively and strong support rod body, so easy to use, effect is excellent.
