Abstract

The utility model relates to an angle changeable member connector, which is used for connection of various members and is capable of optionally changing a connection angle. Heads of two connecting rods are respectively provided with a frame and a groove-shaped ratchet wheel. The groove-shaped ratchet wheel is hinged on the frame through a rivet. The frame is also provided with a ratchet pawl which is provided with a restoring spring. The ratchet pawl is fixed on the frame through the rivet. The ratchet pawl and the groove-shaped ratchet wheel are combined together through the restoring spring. The rivet in the groove-shaped ratchet wheel is also provided with an abnormal cam for controlling combination or separation of the ratchet pawl and the groove-shaped ratchet wheel. The connector has the advantages of simple structure and safe and convenient operation and is capable of optionally adjusting the angle between two members.

Description

Become angle member connector

The utility model relates to a kind of member connector, is used for the connection of various parts, can arbitrarily change connection angle.

The member connector is of many uses, and wherein great majority are used on the furniture, and the furniture of Chu Shouing such as seat, sofa etc. all are by adjust the angle of backrest with the whole method that is connected and fixed the part screw of hand adjustment in the market, and are very inconvenient, can not arbitrarily adjust.

The purpose of this utility model is the shortcoming that overcomes existing connector, and a kind of connector of arbitrarily adjusting member fastening angle automatically is provided, and can be used on furniture and need adjust on the articles for use of angle with other.

The technical solution of the utility model is to realize like this, a kind of change angle member connector, it is special be in: it is that head at two connecting rods is separately installed with framework and flute profile ratchet, by rivet the flute profile ratchet is hinged on the framework, the ratchet of band return spring also is installed on framework, be fixed on the framework with rivet, by return spring ratchet and flute profile ratchet are combined, be combining or disengagement of control ratchet and flute profile ratchet, a special-shaped cam also is installed on the rivet in the flute profile ratchet, the protrusion position is arranged on its edge, hollow groove, before, back push and block, when the ratchet connecting rod turns to limit position up and down, its edge and special-shaped cam rotation, make on the special-shaped cam before, back push and block contact, promote that different parts contacts with ratchet on the special-shaped cam, the working state of control connection device.

The utility model advantage compared with prior art is simple in structure, can adjust the angle between two members arbitrarily, and is safe and reliable, easy to operate.

Now describe the utility model most preferred embodiment in conjunction with the accompanying drawings in detail:

Fig. 1 is for becoming the structural representation of angle member connector;

Fig. 1-a is a plan view;

Fig. 1-b is a plan view;

Fig. 2 is a flute profile ratchet structure schematic representation;

Fig. 3 is the frame structure schematic representation that has the return spring ratchet;

Fig. 4 is special-shaped cam structure schematic representation;

Fig. 5-a ratchet and ratchet disengaged condition figure;

Fig. 5-b ratchet and ratchet bonding state figure.

Among the figure: 1, connecting rod 4, ratchet 7, flute profile ratchet

2, return spring 5, framework 8, special-shaped cam

3, rivet 6, rivet 9, connecting rod

A, D connecting rod edge

Forward and backward push and block on a, the d cam

B, cam edge are protruded the position

Hollow groove on c, the cam

A kind of change angle member connector such as Fig. 1,2,3,4, shown in 5, it is at two connecting rods 1,9 head is separately installed with framework 5 and flute profile ratchet 7, by rivet 6 flute profile ratchet 7 is hinged on the framework 5, the ratchet 4 that has return spring 2 also is installed on framework 5, be fixed on the framework 5 with rivet 3, by return spring 2 flute profile ratchet 7 and ratchet 4 are combined, be combining and disengagement of control flute profile ratchet 7 and ratchet 4, a special-shaped cam 8 also is installed on the rivet in flute profile ratchet 7, the position b of protrusion is arranged on its edge, hollow groove c, before, back push and block a, d, when the connecting rod 9 of connector turns to its edge limit position up and down, the A of its edge, D and special-shaped cam 7 are gone forward, back push and block a, during the d contact, connecting rod 9 promotes special-shaped cam 7 and rotates, protrusion position b or hollow groove c on the special-shaped cam 7 are contacted with ratchet 4, when the protrusion position b on the cam 7 contacts with ratchet 4, ratchet 4 is pressed onto the below, ratchet 4 and flute profile ratchet are thrown off shown in Fig. 5-a, make connector be in relieved state; When ratchet 4 was absorbed in hollow groove c, ratchet 4 contacted with flute profile ratchet 7 again, and combination again shown in Fig. 5-b, makes connector in running order.
