Description

Folding part

Technical Field

The utility model relates to a folding part, in particular to can be applied to folding bicycle or foldable electric scooter's folding part.

Background

Energy conservation and emission reduction are advocated all over the world, and China is a countless county of bicycles and electric vehicles. Because of its portability and small occupied space, the foldable bicycle has become a very important kind of bicycle and has a tendency to become more and more popular.

Most of the existing folding bicycles are provided with a folding joint at the middle part of the bicycle frame or at the position of a vertical tube. For example, chinese patent CN201520268853.3 discloses a "folding joint clamping device", in which a joint i, a joint ii and a handle are hinged together through a shaft pin i, and a locking block is connected together through an adjusting screw, a spring, a pull rod, a pull ring and a connecting pin; one end of the shaft pin is locked by a locking screw.

In the prior art, there are other embodiments regarding the fixing of the hinge shaft of two folding joints, such as that one end of the hinge shaft is a hole and the other end is a screw to block the pin shaft; or, the clamp spring is used at two ends or one end of the hinged shaft; furthermore, the outer diameter of the articulated shaft is provided with a groove and is connected by a bolt.

In the existing scheme, the gap between the hinge shaft and the matched hole or groove is easy to be larger and larger in the using process; the hinge shaft is rocked in the hole or the groove, so that abnormal sound is easily generated, and potential safety hazards exist in use. In addition, the original two parts are combined, if the surface is increased in thickness, the finished surface is easily damaged due to the irregular periphery at the position of the rotating hinge, and the appearance effect is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a folding part that folding is convenient, firm reliable, simple structure, easily manufacturing simultaneously.

The utility model discloses a realize like this: a folding component comprises a first component and a second component which are hinged and connected through a hinge shaft, wherein the side of the first component is provided with a first lug, the side of the second component is provided with a second lug, the first lug is in snap fit with the second lug, and the hinge shaft passes through the through hole of the first lug and is connected with the second lug; the hinge shaft is radially provided with a groove, the second lug is radially provided with a through hole, the connecting piece penetrates through the through hole, and the front end of the connecting piece is inserted into the groove of the hinge shaft.

The connecting piece is a C-shaped cylindrical elastic pin with an opening at the side edge.

The connecting piece is a machine-meter screw with an external thread, the groove of the hinge shaft is provided with an internal thread, and the internal thread is matched with the external thread.

The connecting piece is a common cylindrical pin.

After the connecting piece is assembled, the tail end of the connecting piece is lower than or flush with the outer surface of the second lug.

The tail end of the connecting piece is provided with a tool groove.

The utility model discloses folding part is provided with the through-hole radially at the second lug, and the hinge is radial to be provided with the recess, can realize the fixed connection to the hinge through single connecting piece, and mounting process is simple and convenient, practices thrift the cost, and locking is firm. Meanwhile, the connecting piece is sunken in, so that scraping damage cannot be formed, and the surface effect cannot be damaged in rotation.

Detailed Description

The folding member of the present invention will be described in further detail with reference to fig. 1 to 6.

As shown in fig. 1 to 4, the folding component comprises a first component 1 and a second component 2 which are hinged and connected through a hinge shaft 3, wherein the side of the first component is provided with a first lug 11, the side of the second component is provided with a second lug 21, the first lug is in snap fit with the second lug, and the hinge shaft passes through the through hole of the first lug and is connected with the second lug; the hinge shaft is radially provided with a groove 31, the second lug is radially provided with a through hole 211, the connecting piece 4 penetrates through the through hole, and the front end of the connecting piece is inserted in the groove of the hinge shaft.

There are various embodiments of the connecting member, one of which is a C-shaped cylindrical spring pin with a side opening 41, as shown in fig. 5 and 6.

In the second embodiment, the connecting piece is a screw with an external thread, the groove of the hinge shaft is provided with an internal thread, and the internal thread is matched with the external thread.

In a third embodiment, the connecting member is a common cylindrical pin.

In each of the above embodiments, after the connector is assembled, the tail end of the connector is lower than or flush with the outer surface of the second lug. This does not create scratches nor affect the appearance. When the repair is needed, the tool groove at the tail end of the connecting piece can be taken out only by screwing the tool.

The folding component can be widely applied to traffic and entertainment sports products such as folding bicycles, folding electric vehicles, folding scooters and the like.

The present invention is illustrated schematically by "first" and "second", wherein "first" and "second" can be interchanged.
