Abstract

The utility model relates to a multiple camshaft gemel, which aims at solving the technical problem of the deformation twist of an object after marginal abrasion easily caused by an uneven gravity. For solving the technical problem, the utility model includes a door bracket and a hinge axis which is inserted in the door bracket, the hinge axis is sleeved with a spring which is characterized in that the hinge axis is also sleeved with more than one inside camshafts and more than two outside camshafts which are clamped with the inner camshafts. Because the utility model adopts the structure, the utility model is composed of more than one inside camshafts and more than two outside camshafts, whose two sides are provided with outside camshaft shafts and springs as a standard by the inside camshafts, so the reciprocal action direction is uniformly distributed to two directions thereby keeping the balance and making the switch action stable and soft, the utility model prevents the abrasion, increases the service life and effectively prevents the deformation twist and the damage of the exterior appearance of the object.

Description

Many camshafts hinge

Technical field

The utility model relates to a kind of hinge, specifically a kind of many camshafts hinge.

Background technology

Existing hinge means is widely used in fields such as tame electrical article, mechanical device, is used for the switch of control gate, makes the switch of door can keep stable state.Such as kimchi refrigerator, the cabinet door is located at the top of cabinet, reveals in order to prevent cold air, and general incomplete the opening of cabinet door only is opened to 30 ° or 60 °.Since more when taking out reserve, therefore need Hinge for cupboard door when open mode, can keep stable halted state.A kind of camshaft hinge 100 as shown in Figure 1 can be used for kimchi refrigerator, and it comprises the evagination wheel shaft 110 in the hinge axle housing 140 that is arranged on the cabinet, the axle housing, an inner camshaft 120 and a spring 130.Because the camshaft of the hinge of this structure is arranged on a side of hinge, so the gravity during switch is partially in a side, and taking place easily, decreases eccentric wear, the life-span of hinge and the soundness of action there is very big influence, the feasible object torsional deformation that this hinge has been installed, can't keep balance, appearance damage between face and the face.

Summary of the invention

The utility model is inhomogeneous for the gravity that solves the prior art existence, eccentric wear takes place easily decrease technical problems such as causing the object torsional deformation.

In order to solve the problems of the technologies described above, the utility model comprises a body carriage and the hinge axis that is inserted on the body carriage, be with spring on the hinge axis, it is characterized in that: at the evagination wheel shaft more than two that also is with more than one inner camshaft on the hinge axis and is interlocked with inner camshaft.

Also have following feature in the utility model: the centre of described inner camshaft is the axis hole that is enclosed within on the hinge axis, is provided with outstanding, two ends and is semicircular camshaft contact site, and is fixed on the fixed part on the body carriage on inner camshaft; Described external cam thrust collar is in the left and right sides of inner camshaft, and is enclosed within on the hinge axis, and the outside of camshaft also is provided with spring outside.

Also have following feature in the utility model: described evagination wheel shaft includes in the cam axial plane of helical type curve and the restriction prevention groove of angle of revolution and the inserting groove at top.

Also have following feature in the utility model: described door body carriage comprises fixed head and forms the biside plate of one with fixed head, biside plate is provided with hinge shaft hole, there is a prominent edge below of fixed head, and the fixed head that has prominent edge is inserted in the inserting groove at evagination wheel shaft top.

In the utility model, also has following feature: be provided with the spring joint portion on the lateral surface of camshaft outside.

The utlity model has following advantage and good effect: because the utility model has adopted said structure, constitute by more than one inner camshaft and the evagination wheel shaft more than 2, and be benchmark with the inner camshaft, both sides are provided with evagination wheel shaft and spring, and therefore counter having an effect to the both direction uniform distribution can be kept in balance, make switch motion stable and soft, prevent the eccentric wear damage, improved application life, prevented the torsional deformation and the outward appearance damage of object effectively.

The specific embodiment

Referring to Fig. 1～Fig. 9, many camshafts of the utility model hinge 1 comprises a body carriage 10 and the hinge axis 40 that is inserted on the body carriage 10, be with spring 60 on the hinge axis 40, two the evagination wheel shaft 50 that on hinge axis 40, also is with an inner camshaft 20 and is interlocked with inner camshaft 20.The centre of inner camshaft 20 is the cam ring axis hole 25 that is enclosed within on the hinge axis 40, being provided with outstanding, two ends on inner camshaft 20 is semicircular camshaft contact site 21, and be fixed on fixed part 22 on the body carriage 10, have the engagement groove 27 that can be inserted on body carriage 10 protuberances 15 on the fixed part 22; Two evagination wheel shafts 50 are buckled in the left and right sides of inner camshaft 20, and are enclosed within on the hinge axis 40, also are provided with two relative springs 60 in the outside of two evagination wheel shafts 50.Evagination wheel shaft 50 includes cam axial plane 51 and the prevention groove 53 of the interior angle of revolution of restriction and the inserting groove 55 at top of helical type curve.During with the open revolution of decided angle, the prevention groove 53 of evagination wheel shaft 50 is stopped revolution by 21 backstops of inner camshaft contact site when opening the door.Door body carriage 30 comprises fixed head 31 and forms the biside plate 33 of one with fixed head, and biside plate 33 is provided with hinge shaft hole 35, and it is one prominent along 37 that the below of fixed head 31 has, have in the inserting groove 55 that prominent fixed head 31 along 37 is inserted in evagination wheel shaft 50 tops in.The lateral surface of camshaft 50 is provided with spring joint portion 57 outside, and spring joint portion 57 can form groove or the protuberance that spring 60 ends are pressed from both sides, thereby can combine with spring 60 better.
