Detailed Description
In order to make the technical solution, the purpose and the advantages of the present invention more apparent, the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1, a cart with a buffering device comprises a bottom plate 1 horizontally arranged and wheels 6 arranged on the lower side of the bottom plate 1, wherein the buffering device is arranged between the bottom plate 1 and the wheels 6, the buffering device comprises a support group, the support group comprises a first support rod 3 and a second support rod 5 which are arranged in an X-shaped cross manner, and the cross positions of the first support rod 3 and the second support rod 5 are connected through a rotating shaft; the top ends of the first support rod 3 and the second support rod 5 are connected with the bottom plate 1 through a rotating shaft, and the bottom ends of the first support rod 3 and the second support rod 5 are respectively connected with a wheel 6; the upper section of the first support rod 3 and/or the second support rod 5 is connected with a shock absorber 4 with the bottom of the bottom plate 1. The upper side of the bottom plate 1 is connected with a push rod 2.
The support sets are arranged in two groups, the two groups of support sets are arranged in parallel, and the two groups of support sets are connected to the cross position between the corresponding first supporting rod 3 and the second supporting rod 5 through the support shaft 7 and the rotating shaft. The dampers 4 are provided with at least two sets, wherein the two sets of dampers 4 are symmetrically arranged with respect to the crossing position between the first support bar 3 and the second support bar 5. When the shallow shakes through unevenness's ground, the vertical direction's that bottom plate 1 received effort can be cushioned to the bumper shock absorber 4 of symmetric distribution, and then weakens the vibrations that the automobile body received. In the present embodiment, the damper 4 is a tube damper.
An elastic part 8 is connected between the two ends of the lower section of the first support rod 3 and the second support rod 5, and the elastic part 8 applies a restoring elastic force which is in opposite leaning connection to the first support rod 3 and the second support rod 5. The elastic members 4 are provided with at least two, and the elastic members 4 are arranged side by side and arranged in parallel with respect to the base plate 1. In this embodiment, the elastic member 4 is a spring. When the cart is not carrying goods, the spring is in a natural extension state; when the cart carries goods, the gravity of the heavy object makes the bottom wheels 6 of the first support rod 3 and the second support rod 5 move outwards, and the spring stretches at the moment to enable the spring to apply restoring elasticity which is in opposite abutting joint to the first support rod 3 and the second support rod 5. On the other hand, the elastic part 8 is connected with the first supporting rod 3 and the second supporting rod 5, and partial vertical direction acting force received by the first supporting rod 3 and the second supporting rod 5 is converted into stress release of the horizontal direction through the elastic part 8, so that acting force of the vertical direction is further buffered.
According to the trolley with the buffer device, when the trolley vibrates through the rugged ground, the symmetrically distributed shock absorbers 4 can buffer the action force of the bottom plate 1 in the vertical direction, so that the vibration of the trolley body is weakened. Simultaneously, the gravity of heavy object makes first bracing piece 3 and second bracing piece 5 receive the effort of vertical direction, through the setting of elastic component 8, makes the partial vertical direction effort that first bracing piece 3 and second bracing piece 5 received turn into the stress release of horizontal direction through elastic component 8 to further cushion the effort of vertical direction, protect the safety of article more comprehensively, guarantee the stationarity of removal.
The above description is only a preferred embodiment of the present invention, and those skilled in the art may still modify the described embodiment without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as the protection scope of the present invention.
