Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
The following detailed description is exemplary in nature and is intended to provide further details of the invention. Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention.
Referring to fig. 1, the utility model provides an electric power tool box capable of climbing stairs, which comprises a box body 1, wherein 4 universal wheels 11 are arranged at the bottom of the box body 1; the top of the box body 1 is provided with a handle 12. One side of the box body 1 is provided with two mounting cavities 10, and each mounting cavity is internally provided with a stair climbing ratchet wheel structure.
The stair climbing ratchet structure comprises a first ratchet wheel 2, and the first ratchet wheel 2 is installed in the installation cavity 10 through a rotating shaft 21. The rotating shaft 21 is also coaxially and fixedly provided with a second ratchet wheel 3; a non-return pawl 4 is arranged on the mounting cavity 10, and the root part of the non-return pawl 4 is hinged on the inner wall of the mounting cavity 10; the non-return pawl 4 and the second ratchet wheel 3 form a ratchet mechanism; a stop block 42 for preventing the reverse rotation of the non-return pawl 4 is arranged beside the non-return pawl 4; the backstop pawl 4 is connected with a tension spring for resetting the backstop pawl 4.
The first ratchet teeth 22 and the second ratchet teeth 23 are oppositely directed. The first ratchet teeth 22 of the first ratchet 2 are used for climbing stairs to grasp the ground, so the first ratchet 2 is rotated reversely relative to a conventional ratchet so that when a maintenance worker drags the tool box to grasp the surface of the stairs through the front end protrusions of the first ratchet teeth 22 of the first ratchet 2, the stair is advanced upwards by pulling continuous rotation; meanwhile, the second ratchet wheel 3 rotates in the forward direction, and in the process of the forward rotation, the non-return pawl 4 continuously slides over the ratchet wheel tooth back of the second ratchet wheel tooth 32 and is clamped into the next ratchet wheel tooth groove. Because the first ratchet wheel 2 and the second ratchet wheel 3 are coaxially fixed on the rotating shaft 21, if the first ratchet wheel 2 rotates in the forward direction, the non-return pawl 4 is clamped in the ratchet wheel tooth groove of the second ratchet wheel tooth 32, and the resistance value of the first ratchet wheel 2 rotates in the forward direction, so that the first ratchet wheel 2 cannot rotate in the forward direction due to the action of the ratchet wheel mechanism formed by the second ratchet wheel 3 and the non-return pawl 4 in the stair climbing process, and the tool box cannot fall down stairs.
Referring to fig. 3, the handle 12 includes three sections: a first section 120, a second section 121, and a third section 122; the second section 121 and the third section 122 adopt a drawing structure, and the third section 122 can be received in the second section 121. One end of the second section 121 is hinged with the first section 120, so that the angle between the second section 121 and the first section 120 in the handle 12 can be adjusted according to actual conditions when a service worker uses the handle. When not in use, the third section 122 is received in the second section 121, and the second section 121 naturally droops and is received between the two first sections 120, so that the whole handle 12 is shortest.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
