Description
Technical Field
The invention relates to an overspeed braking bearing traveling wheel of a manual sliding door.
Background
The hangar door and the large-scale factory building door are mostly manual type push-pull door, because the manual push-pull is with uneven effort, lead to the door walking speed to stumble, because the door body dead weight is great with the volume, under acceleration and inertial action, the door body running speed can be faster and faster, relies on the manpower to be unable to master the speed reduction or the stop of door body this moment.
Disclosure of Invention
The invention aims to overcome the original defects, and the speed reducing mechanism is additionally arranged at present, so that the speed can be automatically reduced when the running speed of the door body is uneven, and the manual control is facilitated.
The aim of the invention is achieved by the following technical scheme: the utility model provides a manual push-and-pull door overspeed braking bearing traveling wheel, includes the walking wheel, and the walking wheel is installed on the walking wheel fixing base, and the walking wheel surface is equipped with the ring arch, is equipped with a plurality of recesses along circumference partition position on the ring arch, and the recess is protruding to divide into a plurality of equal segmentation with the ring, and every recess one side all corresponds and is equipped with the collision piece, installs the pendulum board on the walking wheel fixing base, and pendulum board mounting point below floats in walking wheel surface setting, and the one side middle part towards the ring arch on the pendulum board is connected with the lug.
Preferably, one side of the suspension swing plate, which is opposite to the bulge of the circular ring, is provided with a stop block, and the axis of the suspension swing plate is connected with one end of a torsion spring, and the other end of the torsion spring is connected to the suspension swing plate body.
Preferably, the number of grooves is three or more.
Preferably, the axis of the travelling wheel is coincident with the central line of the collision block, the collision block is of an isosceles trapezoid structure, the side of the collision block facing the center of the travelling wheel is the upper side, the width of the groove is 40mm, the length of the upper side is smaller than the width of the groove, and the width of the lug is smaller than or equal to 20mm.
Compared with the prior art, the invention has the advantages that: the speed reducing mechanism is additionally arranged, so that the speed can be reduced automatically when the running speed of the door body is uneven, and the manual control is facilitated.

Detailed Description
The present invention will be further described in detail with reference to the following examples and drawings for the purpose of enhancing the understanding of the present invention, which examples are provided for the purpose of illustrating the present invention only and are not to be construed as limiting the scope of the present invention.
The manual sliding door overspeed braking bearing traveling wheel comprises a traveling wheel 1, the traveling wheel 1 is arranged on a traveling wheel fixing seat 2, annular protrusions 3 are arranged on the surface of the traveling wheel 1, a plurality of grooves 4 are formed in the annular protrusions 3 along circumference equally-divided positions, the number of the grooves 4 is three or more, the annular protrusions 3 are divided into a plurality of equal sections by the grooves 4, collision blocks 5 are correspondingly arranged on one side of each groove 4, a pendulum plate 6 is arranged on the traveling wheel fixing seat 2, the lower part of a mounting point of the pendulum plate 6 floats on the surface of the traveling wheel 1, and a bump 7 is connected to the middle part of one side, facing the annular protrusions 3, of the pendulum plate 6. One side of the pendulum plate 6, which is back to the annular bulge 3, is provided with a stop block 8, one end of a torsion spring 9 is connected to the axis of the pendulum plate 6, and the other end of the torsion spring 9 is connected to the pendulum plate 6 body.
The axis of the travelling wheel 1 coincides with the central line of the collision block 5, the collision block 5 is of an isosceles trapezoid structure, the side of the collision block 5 facing the center of the travelling wheel 1 is the upper side, the width of the groove 4 is 40mm, the length of the upper side is smaller than the width of the groove 4, and the width of the lug 7 is smaller than or equal to 20mm.
When the device works, namely when a human-powered sliding door body is used, the travelling wheel 1 rotates, when the collision block 5 contacts the protruding block 7, the collision block 5 can pass through the lower part of the collision block due to the shape of the protruding block 7, the protruding block 7 can move towards the circle center direction of the travelling wheel 1 due to the isosceles trapezoid structure of the collision block 5 when the collision block 5 passes through the lower part of the protruding block 7, the protruding block 7 is just located in the groove 4 at the moment, the travelling wheel 1 further rotates, the protruding block 7 collides with the circular ring protrusion 3, the protruding block 7 moves towards the circle center direction far away from the travelling wheel 1 under the action force of the circular ring protrusion 3 and the isosceles trapezoid structure of the collision block 5, and more than one movement is repeated after the circular arc distance of the segmented circular ring protrusion 3, so that the door body can be automatically decelerated, the door can be decelerated due to the fact that large human power is required to be pulled backwards due to the action of inertia, and manual control is facilitated. The stop block 8 prevents the swinging angle of the swinging plate 6 from being too large, and the torsion spring 9 can enable the swinging plate 6 to return to the normal angle.
