Abstract

The utility model discloses a connecting piece composed of a connecting piece A and a connecting piece B connected with the connecting piece A, a first lug boss is arranged in the interior of the connecting piece A, at least a convex step is arranged on one surface of the first lug boss facing to the connecting piece B, a second lug boss is arranged in the interior of the connecting piece B, at least two convex claws are arranged on one surface of the second lug boss facing to the connecting piece A, the connecting piece A and the connecting piece B are connected with each other through the first lug boss, the second lug boss and the convex claws, as the two connecting pieces have relative fixation and relative rotation states so that the defect that the connected object cannot be adjusted when the traditional connecting piece is fixedly connected is overcome and the connecting piece is applicable to lighting field.

Description

A kind of link

Technical field

The utility model relates to a kind of link.

Background technique

The general direct employing screw of traditional link, pin or rivet ways of connecting are fixedly linked connected two-part, and this Placement has the following disadvantages: in a single day connected two-part are fixedly linked, and just cannot adjust again.Such as a kind of directed luminous body (transverse-plug type LED lamp), has directionality owing to it is luminous, when its lamp socket and lamp body adopt be connected with upper type after, again with itself and external stability parts (base on the wall or on the desk lamp) when linking to each other, the luminous surface direction of directed luminous body (transverse-plug type LED lamp) is just fixing, the user can't adjust as required to its luminous surface again, greatly reduces the practicability of directed luminous body (transverse-plug type LED lamp).

The model utility content

The utility model in order to overcome above technical deficiency, provides a kind of link just, overcomes the deficiency that traditional link can't be adjusted connected body after fixedly connected again.

In order to overcome above technical deficiency, the utility model adopts following technological scheme:

A kind of link, form by A link and coupled B link, A link inside is provided with first boss, described first boss face is provided with protruding rank at least to the one side of B link, B link inside is provided with second boss, described second boss face is provided with two dogs at least to the one side of A link, A link and B link are by first boss, second boss and dog are connected, the B link can move around along the dog direction with respect to the A link, when the spacing of first boss and second boss was not less than the height on protruding rank, the B link was rotatable with respect to the A link; When the spacing of first boss and second boss during less than the height on protruding rank, the B link is non-rotatable with respect to the A link.

Described first boss is provided with four protruding rank.

Described second boss is provided with four dogs, and described dog is the elasticity dog.

Preferably, described first boss dorsad the one side of B link be provided with a screens.

Preferably, have and have only in described four dogs a dog when the B link rotates with respect to the A link and screens collide, be used to stop the B link to continue to former direction rotation.

The utility model provides a kind of link, because its two-part link exists relative fixed and relative rotation two states, has overcome the deficiency that traditional link can't be adjusted connected body after fixedly connected again.

Embodiment

Below in conjunction with embodiment and embodiment the utility model is further described:

Link described in the utility model exists relative fixed and relative rotation two states: during the relative fixed state, the protruding component level of A link guarantees that the A link can be used as an integral body with the B link and rotates in the gap of second boss of B link; Relatively during rotation status, the user can be by relatively rotating connected body adjusted between A link and B link.

Embodiment 1:

See also Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6:

Present embodiment provides a kind of link, form by A link 1 and coupled B link 2, A link inside is provided with first boss 11, described first boss face is provided with four protruding rank 12 (as shown in Figure 3) to the one side of B link, B link inside is provided with second boss 21, described second boss face is provided with four dogs 22 (as shown in Figure 5) to the one side of A link, the A link is connected (as shown in Figure 6) by first boss, second boss and dog with the B link, and the B link can move around along the dog direction with respect to the A link.

Described dog is the elasticity dog, guarantees to be unlikely to make dog generation permanent deformation even fracture when A link and B link make up.

During use, draw along the dog direction to push away the B link, making has a displacement between first boss and second boss, and when the spacing of first boss and second boss was not less than the height on protruding rank, the B link was rotatable with respect to the A link, was used to regulate the direction of connected body; When the spacing of first boss and second boss during less than the height on protruding rank, the B link is non-rotatable with respect to the A link, and this moment, protruding rank 12 were arranged in the gap of second boss, played the effect (as shown in Figure 6) of B link with respect to the rotation of A link that stop.

Embodiment 2:

See also Fig. 1, Fig. 2, Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 8:

During use, draw along the dog direction to push away the B link, making has a displacement between first boss and second boss, and when the spacing of first boss and second boss was not less than the height on protruding rank, the B link was rotatable with respect to the A link, was used to regulate the direction of connected body; When the spacing of first boss and second boss during less than the height on protruding rank, the B link is non-rotatable with respect to the A link, and this moment, protruding rank 12 were arranged in the second boss gap, played the effect (as shown in Figure 6) of B link with respect to the rotation of A link that stop.

Described first boss of the present embodiment one side of B link dorsad also is provided with a screens 13 (as shown in Figure 7).

Have and have only in described four dogs a dog when the B link rotates with respect to the A link and screens collide (as shown in Figure 8); be used to stop the B link to continue to former direction rotation; thereby rotation round about; can protect the components and parts in the connected body like this; such as: between the lamp socket of lamp and lamp body, be provided with this link; between lamp socket and lamp body because there is lead to link to each other; lead is twined even disconnection to unidirectional continuous rotation; the existence of screens 13 carries out clockwise it and alternately rotation counterclockwise, has overcome this defective.
