Specific embodiment

As shown in Figures 1 to 7, a kind of connector, is mainly used for a kind of connector as bridges such as supporters, including in The second empty bolt 1, the second bolt 1 is a hollow straight-bar, and one end of the second bolt 1 offers the first hole 111, the first hole Sliding is provided with the first bolt 2 in 111, and the first bolt 2 can be stretched out to 1 contract of the second bolt or to outside the second bolt 1, be adopted Bridge is installed with the connector of this both ends plug-in mounting structure, one end of the second bolt 1 is plugged by telescopic first bolt 2 On a rod piece, the other end of the second bolt 1 is plugged on another rod piece, so that connector connects two rod pieces to be formed Bridge, therefore connector is avoided to be exposed to the side wall of rod piece, more beautiful using the bridge after the installation of connector, installation is more Convenient, the structure of connector is simple.

There is retention bead 21, retention bead 21 is slidably arranged in the second bolt 1, therefore is limited on first bolt 2 Position protrusion 21 defines the sliding stroke of the first bolt 2, when elastic component 3 forces the first bolt 2 to reach most to outside the first hole 111 Big stroke, retention bead 21 are pushed against the inner wall of the second bolt 1.

Elastic component 3 is provided in second bolt 1, elastic component 3 forces the first bolt 2 to stretch out to outside the second bolt 1, the One bolt 2 retracts in the second bolt 1, can be automatic protruding, therefore the first bolt 2 all has the effect to automatically reset.

The elastic component 3 is threaded through on the first bolt 2, and 3 one end of elastic component is arranged in retention bead 21, and elastic component 3 is another One end is arranged on the second bolt 1, and the structure that elastic component 3 is threaded through on the first bolt 2 makes the compact-sized of connector, and second The size of bolt 1 is small and exquisite, and elastic component 3 is using helical spring.

The side of second bolt 1 has limiting section 112, when one end of the second bolt 1 is plugged on a rod piece, limit Portion 112 is pushed against on rod piece, and the first bolt 2, in forced contraction, limiting section 112 guarantees the limit of the second bolt 1 in bar On part.

The same end of the second bolt 1 is arranged in the limiting section 112 and the first hole 111, when connector is mounted on bridge, Connector is arranged between two rod pieces, and connector only has limiting section 112 to expose between rod piece.

One end of second bolt 1 has the curved end 115 of indent, and the first hole 111 is provided with curved end 115 On, curved end 115 is the end face of limiting section 112, and bridge can be the rod piece composition of the various shapes such as round tube, square tube, arc End face 115 can be adapted to the rod piece of round tube shape.

Second bolt 1 includes first sleeve 11 and second sleeve 12, and limiting section 112 is arranged in first sleeve 11, First bolt 2 is slidably arranged between first sleeve 11 and second sleeve 12, and first sleeve 11 is detachably arranged at second sleeve On 12, first sleeve 11 is disassembled from second sleeve 12, the first bolt 2 and elastic component 3 can be easily from first sets It is disassembled in cylinder 11 and second sleeve 12, therefore dismountable structure facilitates the dismounting of components, and bridge is used When the different rod piece of size is attached, the first sleeve 11 of the curved end 115 of sizes is optional to be attached to second sleeve 12 On.

One end of first sleeve 11 has plug 113, and the other end of first sleeve 11 is limiting section 112, shape on plug 113 At having convex stupefied 114, plug 113 is annulus shape, and convex stupefied 114 specifically in the outer wall of plug 113, and one end of second sleeve 12 has There is the socket 123 of adaptation plug 113, socket 123 is also annulus shape, and the other end of second sleeve 12 is the second hole 121, socket Convex stupefied 114 recess 122 of adaptation is formed on 123, recess 122 is specifically in the inner wall of socket 123, when plug 113 is plugged in On socket 123, convex stupefied 114 are connected in recess 122.

One end of second bolt 1 offers the second hole 121, and the first bolt 2 is slidably arranged in the first hole 111 and the second hole On 121, the first bolt 2 is protruding on the second hole 121 or to contract, therefore the size of the second bolt 1 further contracts It is small, the smooth sliding of the first bolt 2 is realized using the structure in the first hole 111 and the second hole 121.

Using the bridges general process such as this connector connection supporter are as follows: bridge includes the first rod piece 4 and the second rod piece 5, First rod piece 4 and the second rod piece 5 are hollow round tube, and the first rod piece 4 is arc round tube, and the second rod piece 5 is straight round tube, and second The both ends of rod piece 5 pass through connector respectively and are mounted on the first rod piece 4, and the second rod piece 5 has adaptation second in the axial direction The opening 51 of bolt 1, opening 51 run through the second rod piece 5, and the side of the first rod piece 4 offers the location hole of the first bolt 2 of adaptation 41, the second bolt 1 of two connectors is plugged in the both ends of opening 51 respectively, the first bolt 2 of two connectors is pushed back It is moved up into the second bolt 1, and by the corresponding side that the curved end of two connectors 115 fits in the first rod piece 4 respectively Dynamic, when the second bolt 1 is directed at the location hole 41 of the first rod piece 4, the first bolt 2 automatically resets, so that the first bolt 2 is plugged in In location hole 41, so that the first rod piece 4 is fixed on the second rod piece 5 by connector, the bridge after connecting, connector setting exists Between first rod piece 4 and the second rod piece 5, only limiting section 112 be it can be seen that, limiting section 112 is to be clipped in 4 He of the first rod piece Between second rod piece 5, connector is hidden between the first rod piece 4 and the second rod piece 5, therefore the associative perception of bridge is strong.

Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model Within the scope of.
