Abstract

The utility model discloses a pedal bar folding device for Tiaotiao devices, comprising a pedal bar bearing block, a pedal bar, a pivot, a positioning bar, a spring and other components and provided with a main frame bar of a Tiaotiao device for matching. The device is characterized in: The pedal bar bearing block is fixedly connected to the lower end of main frame bar while an extension board extends outwards from the lateral of the pedal bearing block; the extension board is articulated with one end of the pedal bar by the pivot; one slot is respectively arranged on the outer end and upper end of the extension board; one end of the pedal bar is provided with a slide slot for having the pivot embedded and slide in and a positioning bar is arranged at the middle section of the pedal bar; and one end of the spring is fixed to the pedal bar while the other end is fixed to the pedal bar bearing block or the pivot. The spring is tightened to make the pedal bar positioned in the slots at positions corresponding to the positioning bar. The device is easy-to-carry and saves space.

Description

The foot-driven lever folding device of Tiaotiao device

The utility model relates to a kind of foot-driven lever device, relates in particular to a kind of foot-driven lever folding device of Tiaotiao device.

The foot-driven lever of existing Tiaotiao device is fixed, though can support use during use, takes up space very much when not using, and carries also very inconvenient; The creator changes it into pin-jointed structure at first, and finding during test has in the use and can't locate, and the misgivings on the safety are arranged, and therefore, is to set about improvement again, has the utility model to produce eventually.

It is a kind of portable and save the foot-driven lever folding device of the Tiaotiao device in space that the purpose of this utility model promptly provides at the problems referred to above.

The technical scheme that the utility model adopted is: a kind of foot-driven lever folding device of Tiaotiao device, comprise the treadle bearing, foot-driven lever, pivot, member such as backstay and spring, the body frame bar of collocation Tiaotiao device, it is characterized in that: the affixed treadle bearing in the lower end of the body frame bar of Tiaotiao device, and the treadle bearing is stretched out extension board laterally, extension board articulates foot-driven lever one end with pivot, extension board outer end and upper end respectively are provided with a caulking groove, foot-driven lever one end is provided with chute with the sliding pivot of corresponding embedding, the foot-driven lever stage casing is provided with backstay, spring one end is fixed in foot-driven lever and the other end is fixed in treadle bearing or pivot, and spring can draw and make foot-driven lever be positioned caulking groove with the backstay correspondence.

The beneficial effects of the utility model are: in the utility model, spring can draw and make foot-driven lever be positioned caulking groove with the backstay correspondence and use for the user, when folding, the treadle of transporting persons or goods by cart earlier makes backstay break away from caulking groove, the pivot foot-driven lever, the power of spring is drawn and is made foot-driven lever be positioned caulking groove with the backstay correspondence and fold, and therefore, the utility model is easy to carry about with one and saves the space.

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

The explanation of accompanying drawing drawing:

Fig. 1 is an exploded view of the present utility model;

Fig. 2 is assembled sectional view of the present utility model (vertical profile);

Fig. 3 is the stereogram that the utility model is applied to whole Tiaotiao device;

Fig. 4 is one of the operation chart of the utility model when folding (backstay 22 of foot-driven lever 2 breaks away from caulking grooves 13);

Fig. 5 is two (foot-driven lever 2 has pivoted) of the operation chart of the utility model when folding;

Fig. 6 is three (backstay 22 of foot-driven lever 2 is embedded in caulking groove 14) of the operation chart of the utility model when folding.

As shown in Figure 1 to Figure 3, the utility model comprises members such as treadle bearing 1, foot-driven lever 2, pivot 12, backstay 22 and spring 5, and the body frame bar 6 of collocation Tiaotiao device, wherein:

The affixed treadle bearing 1 in the lower end of body frame bar 6, and treadle bearing 1 is stretched out extension board 11 laterally, extension board 11 articulates foot-driven lever 2 one ends with pivot 12, extension board 11 outer ends and upper end respectively are provided with a

caulking groove

13,14, foot-driven lever 2 one ends then are provided with the sliding pivot 12 of chute 21 corresponding embeddings, foot-driven lever 2 stage casings are provided with backstay 22, and spring 5 one ends are fixed in foot-driven lever 2 fixed bar 23 of end in addition, and the other end is fixed in the pivot 12 (or being directly arranged in treadle bearing 1) of treadle bearing 1.

As shown in Figure 2, spring 5 can draw and make foot-driven lever 2 be positioned caulking groove 13 with backstay 22 correspondences and use for the user, when folding, as shown in Figs. 4-6, at first as shown in Figure 4, the treadle 2 of transporting persons or goods by cart earlier makes backstay 22 break away from caulking groove 13, again as shown in Figure 5, pivot foot-driven lever 2, at last as shown in Figure 6, the power of spring 5 is drawn and is made foot-driven lever 2 be positioned caulking groove 14 with backstay 22 correspondences and fold.

Comprehensively above-mentioned, the utility model is compared the fixed foot-driven lever that effect is commonly used, and the utility model has really Portable and joint space-efficient effect.
