Detailed Description

The technical solutions in the implementation of the present invention will be made clear and fully described below with reference to the accompanying drawings, and the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the utility model can be used in many occasions, and the utility model provides an embodiment of the application of the suspension structure on the sweeper. As shown in fig. 1 and 2, the sweeper mainly comprises a frame 1, a connecting frame 9, a main wheel 10 and an auxiliary wheel 8, wherein a sweeping roller driven by the main wheel 10 is arranged in the frame 1, and the connecting frame 9 is required to be connected with a tractor when in use. The present suspension structure can be used to adjust the suspension state of the auxiliary wheel 8.

Specifically, as shown in fig. 1 to 4, the embodiment of the present invention provides a suspension structure, which includes a limiting plate 4 and a supporting plate 2, wherein the limiting plate 4 is rotatably disposed on a rack 1, and a first rotation axis (i.e., a rotation axis of the limiting plate 4) is formed on the rack 1; the support plate 2 is rotatably arranged on the rack 1, a second rotating axis (namely, a rotating axis of the support plate 2) is formed on the rack 1, a shaft body 6 capable of being buckled on the limit plate 4 is arranged on the support plate 2, and the shaft body 6 forms a fixed axis (namely, an axis of the shaft body 6) on the limit plate 4; the first rotating axis, the second rotating axis and the fixed axis are parallel to each other, and on the axial projection plane of any one axis, the connecting line of the first rotating axis, the second rotating axis and the fixed axis forms a triangle.

As can be seen from fig. 2 and 4, the rotation track of the limiting plate 4 is a circle, the rotation track of the shaft body 6 is also a circle, the two circles have intersection points, a triangle is formed on the axial projection planes of the fixed axis, the first rotation axis and the second rotation axis formed when the shaft body 6 is buckled with the limiting plate 4, because the triangle has stability, the position of the supporting plate 2 is fixed, and the suspension position of an object suspended at one end of the supporting plate 2 far away from the second rotation axis is fixed. The suspension mode has the advantages of simple structure, convenient use, low manufacturing cost, excellent triangular limiting stability and wide application.

The buckling mode of the shaft body 6 and the limiting plate 4 can be adopted, namely, the limiting plate 4 is provided with a hanging groove 5, and the shaft body 6 is matched with the hanging groove 5; the hanging groove 5 is an arc-shaped groove, and the axis corresponding to the hanging groove 5 coincides with the first rotating axis. As shown in fig. 2, when the suspension groove 5 is a circular arc and the center of the circular arc is concentric with the first rotation axis, the shaft body 6 can enter the suspension groove 5 by rotating the limiting plate 4 and the supporting plate 2, so that the shaft body 6 and the limiting plate 4 can be buckled. The central angle that the arc wall corresponds is 36 degrees, and the size of arc wall can not be too big this moment, also enough lock axis body 6 simultaneously, and the central angle of arc wall also can be other angles about 36 degrees. When the hanging groove 5 is a groove of other shape, although the function of fastening can be basically realized, the use is inconvenient when the fastening is rotated.

The rotation connection mode of the limiting plate 4 and the rack 1 is hinged, the limiting plate 4 is rotatably arranged on the rack 1 through a rotating shaft 3 (namely a hinged pin shaft), and when the shaft body 6 is matched with the suspension groove 5, the supporting plate 2 is abutted against the rotating shaft 3. Through setting up and 2 complex pivots 3 of backup pad, can be convenient seek the position of finding fixed axis, rotate backup pad 2 promptly and make backup pad 2 support pivot 3 when, just can direct rotatory limiting plate 4 make hang groove 5 and detain on the axis body 6 to convenient realization hangs fixedly, improves operating efficiency.

On articulated basis, for the convenience of user's rotation limiting plate 4, the one end that limiting plate 4 kept away from the arc wall is provided with driving lever 7.

As a further development of the utility model, a pressure lever 11 is provided on the support plate 2. The provision of the pressing lever 11 can facilitate the user to rotate the support plate 2.

During the use, can set up two limiting plates 4 and adjust two kinds of states of hanging of jockey pulley 8 in order to make things convenient for the user, one is the level and hangs, one is perpendicular.

When the sweeper is used for sweeping the ground, the auxiliary wheel 8 needs to be horizontally suspended, as shown in fig. 1, the supporting plate 2 is rotated to a horizontal state, the supporting plate 2 abuts against the rotating shaft 3, then the limiting plate 4 is rotated to enable the suspension groove 5 to buckle the shaft body 6, a stable triangle is formed at the moment, and the auxiliary wheel 8 is stably suspended.

Need carry out perpendicular suspension with the auxiliary wheel 8 when not using the machine of sweeping the floor, use driving lever 7 will rotate limiting plate 4 for suspension groove 5 breaks away from axis body 6, then as shown in fig. 2, rotates backup pad 2 to vertical state, then rotates another limiting plate 4, makes limiting plate 4 detain axis body 6, realizes the fixed of auxiliary wheel 8 position.
