Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
The structure and the principle of a four-bar folder according to the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a four-bar linkage folder according to an embodiment of the present invention; FIG. 2 is an exploded view of the four bar linkage folder of FIG. 1; FIG. 3 is a schematic view of a four bar linkage folder shown in FIG. 2 in a fully unfolded state; fig. 4 is a schematic view of a partially unfolded state of the four-bar folder shown in fig. 2. Referring to fig. 1-4, the utility model provides a four-bar linkage folder, it includes a first connecting plate 21, with first connecting plate 21 articulated second connecting plate 22, with first connecting plate 21 articulated handle 23, with second connecting plate 22 articulated regulation pole 24, handle 23 with it is articulated to adjust pole 24, handle 23 adjust pole 24 with first connecting plate 21 and second connecting plate 22 is the four-bar linkage structure, first connecting plate 21 is provided with a recess 211, second connecting plate 22 is provided with a boss 221, works as first connecting plate 21 with when second connecting plate 22 is in the laminating state, boss 221 with the recess 211 interlock is connected.
As shown in fig. 1, the four-bar linkage folder 2 is mounted on a main beam 1 of a frame of a folding bicycle, and divides the main beam 1 into a front main beam 11 and a rear main beam 12, as shown in fig. 2-4, the first connecting plate 21 is fixedly connected to the rear main beam 12, the second connecting plate 22 is fixedly connected to the front main beam 11, and the first connecting plate 21 is hinged to the second connecting plate 22, so that when the first connecting plate 21 and the second connecting plate 22 are in a fit state, the main beam 1 is in an unfolded state, and a rider can use the folding bicycle. When the rider needs to fold the foldable bicycle so as to reduce the occupied space of the foldable bicycle, the folding can be realized by only unfolding the first connecting plate 21 and the second connecting plate 22.
The handle 23, the adjusting lever 24, the first connecting plate 21 and the second connecting plate 22 are of a four-bar linkage structure, so that the four-bar linkage folder 2 has better structural strength on one hand, and on the other hand, the closed or unfolded state of the first connecting plate 21 and the second connecting plate 22 can be conveniently controlled by changing the internal angle of the four-bar linkage.
When the first connecting plate 21 and the second connecting plate 22 are in a fit state, the boss 221 is in snap-fit connection with the groove 211. For example, the area of the boss 221 may be greater than one fifth of the area of the second connection plate 22, and the height of the boss 221 may be greater than one third of the thickness of the first connection plate 21. Therefore, the first connecting plate 21 and the second connecting plate 22 can be guided and positioned when being closed, and the first connecting plate 21 and the second connecting plate 22 are greatly prevented from being dislocated when being closed; the structural strength of the four-bar folder 2 can be enhanced by sharing the shearing force borne by the hinge shaft for hinging the first connecting plate 21 and the second connecting plate 22 with the boss 221 and the groove 211 during the use of the folding bicycle by a rider.
In a preferred embodiment, the handle 23 is provided with a receiving groove 231, and the adjusting lever 24 is received in the receiving groove 231 when the first connecting plate 21 and the second connecting plate 22 are in the attached state. This makes the four-bar folder 2 beautiful and reduces erosion of the hinged portions of the handle 23 and the adjustment lever 24 by external environments such as rain and dust.
In a preferred embodiment, one end of the adjusting rod 24 is an external thread head 241, the other end is provided with an internal thread hole, the adjusting rod 24 is connected with the second connecting plate 22 through a first hinge shaft 25, the first hinge shaft 25 is provided with a hollow through hole 251, the adjusting rod 24 is connected with the first hinge shaft 25 through a screw 26 penetrating through the hollow through hole 251, the adjusting rod 24 is connected with the handle 23 through a second hinge shaft 27, the second hinge shaft 27 is provided with a hollow thread hole 271, and the external thread head 241 of the adjusting rod 24 is in threaded connection with the hollow thread hole 271. This facilitates the assembly of the adjustment lever.
In a preferred embodiment, the handle 23 further comprises a U-shaped connecting member 232 received in the receiving groove 231, the U-shaped connecting member 232 is provided with a hollow through hole at the bottom and at both sides thereof, and the adjusting lever 24 is threaded through the hollow through hole at the bottom of the U-shaped connecting member 232 and the second hinge shaft 27 passing through the hollow through holes at both sides of the U-shaped connecting member 232. The width of the U-shaped connecting member 232 is smaller than the width of the receiving groove 231, so that the relative rotation between the adjusting lever 24 and the handle 23 is not affected, the force bearing point of the adjusting lever 24 can be increased, and the thread wear caused by excessive stress on the external thread head 241 and the hollow threaded hole 271 in the use process is avoided.
The shaft of the adjusting lever 24 may have a polygonal cross section, such as a quadrangular or hexagonal cross section, and the hollow through hole 251 of the first hinge shaft 25 may be partially or entirely identical to the shaft cross section of the adjusting lever 24, so that it is possible to prevent the adjusting lever 24 from rotating during use, thereby preventing the screw connection between the adjusting lever 24 and the screw 26 and the second hinge shaft 27 from being loosened.
In a preferred embodiment, the boss 221 is provided with a receiving groove 222 for receiving the adjustment lever 24 when the first and second connection plates 21 and 22 are in the unfolded state. This ensures that the boss 221 does not affect the movement stroke of the adjustment lever 24 when the first connecting plate 21 and the second connecting plate 22 are in the fully unfolded state.
The utility model provides a four-bar linkage folder, its simple structure, simple to operate, structural strength is good, can effectively prevent folding bicycle's folding position dislocation when the closure, improves folding bicycle's security.
