Abstract
A hand-press folding scooter, wherein a folding press piece (100) is pressed to drive an upper push rod (97) to move downwards so that a lower portion thereof moves to a lower push rod (96) such that parts of racks (962, 971) of the lower push rod and the upper push rod engage together and sequentially push the lower push rod, a pull piece (91) and a steel rope (90) in a linked manner so that a slide pin (92) slides to extend or retract into position slots (12, 13). Thus, pressing the folding press piece downwards causes parts of the racks between the lower push rod and the upper push rod to engage together to fold or unfold the scooter regardless of whether a movable tube (62) of a telescopic rod (6) is in a high position or contracted into place, so that the folding and unfolding operations are not restricted by the position state of the telescopic rod, and it is not necessary to contract the telescopic rod to the shortest state each time the scooter is folded or unfolded, which satisfies people's usual habits for scooter folding and unfolding. The scooter has a more reasonable structure, and is easy to operate with one hand.

从上可以看出,操纵滑板车的折叠、展开,是靠按下收折按压件100带动上推动杆97往下移动的同时使其下部摆向下推动杆96后,使下推动杆96和上推动杆97的一部分条形齿962、971咬合在一起,再联动地依次推动下推动杆96、牵拉件91、钢性绳90后使滑销92滑离展开或收合到位槽来实现的,这样不管伸缩杆的动管是在高位还是收缩到位,只要往下按收折按压件100,都可以使下推动杆96和上推动杆97之间的一部分齿条962、971咬合在一起来实现折叠或展开滑板车,以使其收折、展开操作不受伸缩杆位置状态的限制,从而无需每次在折叠或展开滑板车时都要把伸缩管缩到最短状态才能操作,这就非常符合人们平常收合、展开滑板车的使用习惯,因此本实用新型的结构更合理。As can be seen from the above, when the folding and unfolding of the scooter is operated, the lower push rod 96 and the lower push rod 96 are pushed down while the upper push rod 97 is moved downward by pushing down the retractable pressing member 100 and the lower push rod 96 and A part of the bar teeth 962 and 971 of the upper push rod 97 are snapped together, and then the lower push rod 96, the pulling member 91, and the steel rope 90 are sequentially pushed in a coordinated manner, and the sliding pin 92 is slid away from the unfolding or closing position groove to realize In this way, no matter whether the moving tube of the telescopic rod is in the high position or contracted in place, as long as the folding and pressing member 100 is pressed down, a part of the racks 962 and 971 between the lower push rod 96 and the upper push rod 97 can be snapped together. Get up to realize the folding or unfolding scooter, so that its folding and unfolding operations are not limited by the position of the telescopic rod, so there is no need to retract the telescopic tube to the shortest state before operating the folding or unfolding scooter. It is very in line with people's usual habit of folding and unfolding scooters, so the structure of the utility model is more reasonable.
作为较佳的实施方案,如图8所示,上推动杆97和下推动杆96的齿条971、962的齿形有些倾斜,它们单向咬合(当上推动杆97向下推时才咬合在一起)。As a preferred embodiment, as shown in FIG. 8, the tooth shapes of the racks 971 and 962 of the upper push rod 97 and the lower push rod 96 are slightly inclined, and they engage in one direction (the upper push rod 97 only engages when it is pushed downward). Together).
在本实施例中,在所述上推动杆97的上部中设有条形的导向孔974;所述的牵拉件复位簧94是设在该导向孔974中的压簧;在位于该牵拉件复位簧94下方的导向孔974中设有横销101,其两端横插固定在该动管62的销孔621中,横销除了给上推动杆的97稍微倾斜地上下移动起导向外,还可以给压簧对上推动杆的作用提供支承。In this embodiment, a strip-shaped guide hole 974 is provided in the upper portion of the upper push rod 97; the puller reset spring 94 is a compression spring provided in the guide hole 974; A transverse pin 101 is provided in the guide hole 974 below the pull-piece return spring 94, and both ends thereof are inserted and fixed in the pin hole 621 of the moving pipe 62. The horizontal pin moves upwards and downwards slightly to guide the 97 of the upper push rod In addition, it can also provide support for the action of the compression spring on the upper push rod.
在本实施例中,如图6、7所示,为便于生产和组装,使所述的下推动杆96分成上部分的齿条部963和管状部964,它们通过销轴103连接;所述的齿条962设在该齿条部963上;所述带弹片1021的推动销102设在该管状部964内。优选地,在所述伸缩杆6内设有使上推动杆97摆离该下推动杆96的推动杆分离推件104,这样当松开收折按压件100,可避免下推动杆96和上推动杆97的齿条962、971仍咬合在一起影响收折结构9的复位。推动杆分离推件104通常是弹性件,它可以是拉簧、压簧或折弯的弹性钢条、弹片等,在如图7所示的本实施例中,它是装在该上推动杆97下端中的V型弹性钢条(其弹力不用很大,当松开收折按压件时,钢条能辅助分开上、下推动件即可),其对向该下推动杆96,当上推动杆下部摆向下推动杆时,弹性钢条一端顶在下推动杆上,而一旦松开收折按压件,在弹性钢条的作用下,上、下推动杆顺利分开。在本实施例中,所述下推动杆96和上推动杆97的齿条962、971在直线方向上分别通过分隔槽965、972分隔成两列,所述弹性钢条设在上推动杆97的分隔槽965中,这样既有助于齿条之间的咬合,又有助于弹性钢条的安装和受力均衡。In this embodiment, as shown in FIGS. 6 and 7, in order to facilitate production and assembly, the lower push rod 96 is divided into a rack portion 963 and a tubular portion 964 of an upper portion, which are connected by a pin 103; A rack 962 is provided on the rack portion 963; the push pin 102 with the elastic piece 1021 is provided in the tubular portion 964. Preferably, a push rod separating pusher 104 is provided in the telescopic rod 6 to swing the upper push rod 97 away from the lower push rod 96. In this way, when the folding pusher 100 is released, the lower push rod 96 and the upper push rod can be avoided. The racks 962 and 971 of the push rod 97 still bite together and affect the reset of the folding structure 9. The push rod separating pusher 104 is usually an elastic member, which can be a tension spring, a compression spring, or a bent elastic steel bar, an elastic sheet, etc. In this embodiment shown in FIG. 7, it is a push rod mounted on the push rod. 97 V-shaped elastic steel bar in the lower end (its elasticity does not need to be very large, the steel bar can assist to separate the upper and lower pushers when the folding and pressing member is released), and it faces the lower push rod 96, when the upper When the lower part of the push rod pushes the rod downward, one end of the elastic steel bar is pressed against the lower push rod, and once the folding and pressing member is released, the upper and lower push rods are smoothly separated by the action of the elastic steel bar. In this embodiment, the racks 962 and 971 of the lower push rod 96 and the upper push rod 97 are separated into two rows by separating grooves 965 and 972 in a linear direction, and the elastic steel bar is provided on the upper push rod 97. In the separation groove 965, this not only helps the meshing between the racks, but also helps to install and balance the elastic steel bars.
上推动杆摆动推件99可以是各种结构,只要当上推动杆下移时能推动它的下部摆向下推动杆,当上推动杆上移复位时能自动摆离下推动杆即可。在本实施例中,上推动杆97和上推动杆摆动推件99通过斜台的方式来实现,如图4、8所示,所述的上推动杆摆动推件99呈管状,其装入到该定管61内;所述上推动杆97上端、下推动杆96上端伸入到该上推动杆摆动推件99的管内;在所述上推动杆的下端上设有斜凸台973,在所述上推动杆摆动推件99的内壁上设有斜推台991,当上推动杆下移时,在斜推台991的作用下就可以使上推动杆下部摆向下推动杆。The upper push rod swing pusher 99 can have various structures, as long as the lower push rod can be pushed down when the upper push rod is moved down, and the lower push rod can be automatically swung away when the upper push rod is moved upward and reset. In this embodiment, the upper push rod 97 and the upper push rod swing pusher 99 are implemented by means of an inclined platform. As shown in FIG. 4 and FIG. Into the fixed pipe 61; the upper end of the upper push rod 97 and the upper end of the lower push rod 96 extend into the tube of the upper push rod swing pusher 99; and the inclined end 973 is provided on the lower end of the upper push rod, An inclined push platform 991 is provided on the inner wall of the upper push rod swing pusher 99. When the upper push rod moves downward, the upper push rod can swing the lower push rod downward under the action of the inclined push platform 991.
优选地,在所述收折按压件100的下部设有斜凸肩,在所述上推动杆上端设有与该斜凸肩相互作用的受力斜面,这样当按下收折按压件100时,有助于使上推动杆的下部摆向下推动杆,从而达到更省力来操作收折结构的目的。Preferably, an oblique shoulder is provided at the lower part of the folding presser 100, and a force-inclined surface interacting with the oblique shoulder is provided at the upper end of the upper push rod, so that when the folding presser 100 is pressed , It helps to make the lower part of the upper push rod push the rod downward, so as to achieve the purpose of more effortless operation of the folding structure.
本实施例所示的滑板车是双把手的。The scooter shown in this embodiment is a two-handle.
