Abstract
The utility model provides a bar folding mechanism which comprises a pin shaft arranged between two bars that rotate relative to each other. The bar folding mechanism is characterized in that the two bars and bushings are connected together through the pin shaft, a compaction block is arranged on either of the two bars, a locking sleeve is sleeved on the other bar, and compaction threads are arranged between the locking sleeve and the compaction block and matched to each other. Since the bar folding mechanism rotates around the pin shaft to achieve the folding operation, the two bars are locked by the compaction block and the locking sleeve on the bars when opening. The bar folding mechanism has simple structure and convenient folding operation, and is applied to the handle bar of the scooter or the bicycle.
Description
Technical field:
The utility model relates to a kind of rod member fold mechanism.
Background technology:
For dwindling the volume that transports and carry in the process, the handlebar of existing Kickboard Scooter and bicycle is typically provided with the rod member fold mechanism.A kind of " folded tube " just disclosed for No. 200720140600.3 as Chinese patent.In this technical scheme, folded tube includes: connection pipe on, a block nut, an intermediate connecting rod, vertical tube, an and lower link once.Last connection pipe is provided with that rank, stage casing shapes ring is protruding, taper portion and articulated section, bottom; Block nut is provided with the shape hole of running through, rank, and shape hole, rank comprises that keeping supplying connection pipe wears the path hole of passing through, and encircles the hole, big footpath of protruding ccontaining slippage with one for rank shapes, and hole, big footpath opening is provided with negative thread; The two ends of intermediate connecting rod have first articulated section and second articulated section, and first articulated section is taken over the articulated section, bottom and articulated with linking; Following vertical tube is provided with the class hole of running through, and position, following vertical tube top is provided with the outside thread of establishing for block nut negative thread lock.Above-mentioned folded tube can be finished function folding and locking, but there is complex structure in it, the deficiency that manufacturing cost is high.
Summary of the invention:
The purpose of this utility model is: the rod member fold mechanism that a kind of simple in structure, folding convenient is provided.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of rod member fold mechanism, be provided with bearing pin between two relatively turnable rod members, it is characterized in that: two rod members and lining link together by bearing pin, and compact heap is installed on the rod member, lock sleeve is enclosed within on another rod member, is provided with the collet threaded that matches between lock sleeve and compact heap.
Advantage of the present utility model is: because the utility model is that the center rotation is folding with the bearing pin, by being installed on compact heap and the lock sleeve on the rod member, realize locking when two rod members are opened.It is simple in structure, and folding convenient is adapted at using on the handlebar of Kickboard Scooter or bicycle.
In the utility model, described lining is provided with the perforate of installation member and is used for the folding fluting of rod member.It is folding that it is beneficial to rod member.
In the utility model, described compact heap bottom is provided with outside thread, and compact heap is provided with the special-shaped block of projection, and a conical surface is arranged at the special-shaped block top of projection, and the special-shaped block of projection is stuck in the fluting of lining, and can slide vertically.When screwing collet threaded, the conical surface of the special-shaped block of projection contacts with the inner conical surface of lock sleeve, forces special-shaped projection elastic deformation toward the center extruding, reaches to connect and the antibacklash purpose.
In the utility model, there is the conical surface at described lock sleeve inner chamber position, and negative thread is arranged at the bottom, and lock sleeve can slide on rod member.When screwing collet threaded, the conical surface of the special-shaped block of projection contacts with the inner conical surface of lock sleeve, forces special-shaped projection elastic deformation toward the center extruding, reaches to connect and the antibacklash purpose.
In the utility model, the rod member of described compact heap below is provided with jump ring.Jump ring can limit the axial stroke scope of compact heap, makes lock sleeve more convenient with being connected of compact heap.
Description of drawings:
Scheme drawing when Fig. 1 is the utility model open mode.
Scheme drawing when Fig. 2 is the utility model folded state.
Cutaway view when Fig. 3 is the utility model folded state.
Cutaway view when Fig. 4 is the utility model open mode.
The specific embodiment:
In conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: the rod member fold mechanism of present embodiment comprises: two 1,2 of relatively turnable rod members are provided with bearing pin 3.Two rod members 1,2 and lining 4 link together by bearing pin 3, and compact heap 5 is installed on the rod member 1, and lock sleeve 6 is enclosed within on another rod member 2, and 5 of lock sleeve 6 and compact heaps are provided with the collet threaded that matches.
The present embodiment operating process is as follows: when folding, unclamp lock sleeve and on draw lock sleeve, amount to rod member, two rod members rotate around bearing pin, promptly finish folding work.When opening, the pull-up rod member makes two rod members be in same axis, and lock sleeve glides, and utilizes the collet threaded between lock sleeve and compact heap, tightens lock sleeve, promptly finishes the work of opening.
Because the utility model is the center with the bearing pin to rotate foldingly, by being installed on compact heap and the lock sleeve on the rod member, can realize that two rod members open locking, it is simple in structure, and folding convenient is adapted at using on the handlebar of Kickboard Scooter or bicycle.When screwing collet threaded, the conical surface of the special-shaped block of projection contacts with the inner conical surface of lock sleeve, forces special-shaped projection elastic deformation toward the center extruding, reaches to connect and the antibacklash purpose.
Above embodiment only is a case of the present invention, and any replacement that spirit is done according to the present invention all is interpreted as not breaking away from protection scope of the present invention.
