Description

A kind of button joint

Technical field

The utility model relates to a kind of syndeton, relates in particular a kind of button joint.

Background technology

for the joint that is used between rod member connecting with and can carrying out folding, the connector that for example arranges between two rod members that connect of tent is to realize expansion and the folding between two rod members, its general structure that adopts the unidirectional connector of U-shaped groove, or the connector of two pivot bush units, all need by rivet with two its be hinged, both pivot joint and rotations take rivet as axle, and the internal constructions such as the upper corresponding locking screens of cooperation or back-moving spring, so that it rotates more flexible and can fix when supporting expansion, such structure is comparatively complicated, assemble also more loaded down with trivial details, and some connector is for coordinating folding, also must carry out pull when folding bounces back reach the expansion between two connectors and fold, such connector operation is more painstaking, inconvenient to use, and adopt between connector or in connector more complicated part etc. to assemble, material cost and assembly cost have been increased.

The utility model content

The purpose of this utility model is to provide a kind of button joint, and it is simple in structure, and convenient folding is linked and packed between rod member convenient and swift.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of button joint, it comprises joint sleeve and the ball and socket joint that is connected to two Rod end, ball and socket joint is actively socketed between two auricles of joint sleeve by a pin, be provided with a draw-in groove above ball and socket joint, the top of joint sleeve is articulated with a pressing plate, pressing plate locates to be provided with a snap fit that coordinates with above-mentioned draw-in groove below the end of nearly ball and socket joint, the other end of pressing plate is held by a spring.

Described pressing plate is articulated between two auricles of joint sleeve, and pivot is positioned at the nearly middle part of pressing plate.

One button is located at the top that is positioned at spring on pressing plate.

After adopting said structure, button joint of the present utility model is by joint sleeve and the ball and socket joint of two pivot bush units, by the snap fit on the joint sleeve center platen and the draw-in groove snapping in ball and socket joint are realized joint sleeve and ball and socket joint are connected and fixed, and be provided with the button that presses down on pressing plate, regulate by button lift on an end of pressing plate after, make snap fit disengaging draw-in groove in pressing plate, thereby make ball and socket joint break away from the fastening locking of joint sleeve, both can realize turnover downwards and closing realizes leaning on folding between two rod members.

The specific embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

As shown in Figure 1 and Figure 2, button joint of the present utility model, comprise the joint sleeve 1 and the ball and socket joint 2 that are connected on two

rod members

10,20 ends, wherein, ball and socket joint 2 is actively socketed among two auricles 11 of joint sleeve 1, be respectively equipped with pivot hole 12,21 in joint sleeve 1 and ball and socket joint 2 the place aheads, thereby by pin 3, ball and socket joint 2 be articulated between two auricles 11 of joint sleeve 1.

For making joint sleeve 1 and ball and socket joint 2 can locate and form firm support when the deployed condition, but the easy adjustment joint launches between two rod members to support or the folding closing realizing smoothly simultaneously.In the utility model, be provided with a draw-in groove 22 above ball and socket joint 2 front ends, simultaneously be provided with a pressing plate 4 above joint sleeve 1, pressing plate 4 is articulated between two auricles 11 of joint sleeve 1, and makes that pivot 40 is middle part or the nearly middle parts that are positioned at pressing plate 4.The place, below of the end of pressing plate 4 nearly ball and socket joints is provided with a snap fit 41, snap fit 41 coordinates with draw-in groove 22 in ball and socket joint 2, when ball and socket joint 2 is connected in joint sleeve 1 and both be parallel, thus snap fit 41 be fastened on make in draw-in groove 22 be connected between ball and socket joint 2 and joint sleeve 1 after the location.The other end of pressing plate 4 is that an end of nearly rod member 10 is held by a spring 6, and has a button 5 to be located at the top that is positioned at spring 6 on pressing plate 4, and button 5 can be and connects a circular press button that is positioned on pressing plate 4.Establish a spring 6 between pressing plate 4 and joint sleeve 1, spring 6 is positioned at the below of button 5, when button 5 pressed down, the spring 6 between 1 liang of auricle 11 of joint sleeve was to lower compression, after an end of pressing plate 4 nearly rod members 10 presses down, the other end is lifted on, thereby snap fit 41 upwards lifts, and deviates from from draw-in groove 22, and two ball and socket joints 2 break away from the locking relation with joint sleeve 1, ball and socket joint 2 is the latter two closings of rotation relatively in joint sleeve 1, and drive

rod member

10,20 is received and leaned on.

Shown in Fig. 3 A to Fig. 5 B, be the operating state graph of a relation of button joint of the present utility model.During in open mode, two

rod members

10,20 are launched into holding state when joint, and ball and socket joint 2 connects and is positioned between joint sleeve 1, and the snap fit 41 of pressing plate 4 is buckled in the draw-in groove 22 of ball and socket joint 1, and spring 6 is relaxed state in joint sleeve 1.when needs carry out folding with two rod members, push button 5, this moment, spring 6 was stressed to lower compression, pressing plate 4 a wherein end is pressed down, the other end upwards lifts, owing to being subject to simultaneously certain material deformation between snap fit 41 and draw-in groove 22, snap fit 41 upwards lifts and breaks away from draw-in groove 22, ball and socket joint 2 breaks away from the locking of joint sleeve 1, both rear folding closings of turnover downwards mutually, realize the folding of rod member 10 and rod member 20, two rod members are two bar closing states from parallel expansion holding state folding, during folding, button 5 removed when snap fit 41 breaks away from draw-in groove 22 press down stressed, and spring 6 also resets and is relaxed state, the state that pressing plate 4 restores balance.Otherwise, two rod members be connected, ball and socket joint 2 activities to joint sleeve, are buckled into the snap fit 41 in joint sleeve 4 in draw-in groove 22 in ball and socket joint 2 and get final product.

Button joint of the present utility model is by joint sleeve 1 and the ball and socket joint 2 of two pivot bush units, ball and socket joint 2 is movably connected in joint sleeve 1, by the snap fit 41 on joint sleeve 1 center platen 4 and draw-in groove 22 snappings in ball and socket joint 2 are realized joint sleeve 1 and ball and socket joint 2 are connected and fixed, and be provided with the button 5 that presses down on pressing plate 4, regulate by button lift on an end of pressing plate 4 after, make snap fit 41 disengaging draw-in grooves 22 in pressing plate 4, thereby make ball and socket joint break away from the fastening locking of joint sleeve, both can realize turnover downwards and closing realizes leaning on folding between two rod members.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
