Detailed Description

To make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described in the embodiments of the present invention with reference to the drawings, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The specific embodiment is as follows:

this embodiment provides a laborsaving push-and-pull door of preventing falling, including door frame 1, door frame 1 includes top beam 101, left crossbeam 102, right crossbeam 103, underframe 104, still including set up in the gyro wheel unit 2 of underframe 104 bottom, set up in underframe 104 bottom is used for supporting the support element 3 of door frame 1, gyro wheel unit 2 includes fixed mounting underframe 104 bottom support 201, set up in universal wheel 202 on the support 201. The rollers of the universal wheel 202 are rubber rollers.

As shown in fig. 1, in the present embodiment, the door frame 1 is hinged to a side frame (not shown) through a door hinge 6, and when the door needs to be opened, the door frame 1 is pushed so that the door frame 1 swings around the door hinge 6, thereby completing the requirement of opening and closing the door. After long-time use of the large door, the door frame 1 may fall and deform due to the action of gravity or the influence of the environment, at this time, the rotating friction force of the door hinge 6 becomes large, the door frame 1 needs to be pushed to overcome a larger resistance, and the door frame 1 may also fall to be in direct contact with the ground, so that when the door frame 1 is pushed, the bottom frame 104 may slide on the ground due to friction.

In order to avoid the above phenomenon, in the present embodiment, the bottom of the bottom frame 104 is provided with a roller unit 2, as shown in fig. 2, the roller unit 2 includes a bracket 201 fixedly installed at the bottom of the bottom frame 104, and a universal wheel 202 disposed on the bracket 201. The universal wheel 202 is in direct contact with the ground, and when the doorframe 1 is pushed, the universal wheel 202 can roll on the ground. Like this the gyro wheel unit 2 is right door frame 1 can play the supporting role of certain degree, and the frictional force on gyro wheel and ground is less moreover, is convenient for constructor to promote fast door frame 1.

In order to avoid the phenomenon that the tire may be deformed or even damaged and cannot be used after being used for a long time due to the heavy weight of the doorframe and the generally weak strength of the tire, please refer to fig. 1 again, the bottom of the bottom frame 104 is provided with a supporting unit 3 for supporting the doorframe 1. In this embodiment, the supporting unit 3 directly contacts with the ground, and thus the door frame 1 is supported, and the falling caused by the excessive gravity of the door frame 1 can be avoided.

Specifically, as shown in fig. 3, the supporting unit 3 includes a supporting frame 5 fixedly installed at the bottom of the bottom frame 104, and a supporting rod 4 hinged to the supporting frame 5. In this embodiment, the support rod 4 directly contacts with the ground to play a role of stable support. But when the door frame 1 is pushed, the support rod 4 is driven to have sliding friction on the ground, and the resistance on the door frame 1 is increased. In order to avoid the above phenomenon, the top end of the support rod 4 is hinged with the support frame 5 in the embodiment. According to the arrangement, when the door frame 1 does not need to be pushed or pulled, the supporting rod 4 is shifted, so that the bottom end of the supporting rod 4 is abutted against the ground, and the supporting rod 4 can play a role in stably supporting the door frame 1; when the door frame 1 needs to be pushed and pulled, the supporting rod 4 is pushed, so that the bottom end of the supporting rod 4 is separated from the ground, the resistance of pushing and pulling the door frame 1 is small, and a constructor can conveniently open and close the door quickly.

Wherein, 4 bottom of bracing piece is hemispherical structure, swings like this during bracing piece 4, the frictional force on bracing piece 4 and ground is less, and the swing is easier, can avoid appearing 4 bottom of bracing piece and the dead condition of ground card.

When the support rod 4 is kept in a vertical state, the support effect on the doorframe 1 is most stable and optimal, however, due to the influence of the external environment, if the doorframe 1 is dropped to a certain extent, the support rod 4 cannot vertically support the doorframe 1 at this time. Therefore, in order to avoid the above problem, in the present embodiment, the supporting rod 4 is a telescopic structure. By adjusting the length of the supporting rod 4, the supporting requirements of different heights can be met.

Specifically, as shown in fig. 4, the support rod 4 includes an outer cylinder 401 and an inner cylinder 402 slidably sleeved inside the outer cylinder 401. In this embodiment, the top end of the outer cylinder 401 is hinged to the supporting frame 301, the bottom end of the inner cylinder 402 abuts against the ground, and the inner cylinder 402 can slide into the outer cylinder 401 to shorten the length of the supporting rod 4.

In order to facilitate quick fixing of the length of the support rod 4, that is, fixing the positions of the inner cylinder 402 and the outer cylinder 401, in this embodiment, as shown in fig. 5, a first screw hole 403 is formed in a side wall of the outer cylinder 401, a plurality of second screw holes 404 adapted to the first screw holes 403 are formed in a side wall of the inner cylinder 402, and the support rod 4 further includes a screw rod 405, where the screw rod 405 passes through the first screw holes 403 and is screwed with the second screw holes 404. Wherein, the second screw holes 404 are uniformly distributed at intervals along the length direction of the inner cylinder 402.

The relative positions of the inner cylinder 402 and the outer cylinder 401 can be locked by screwing the screw 405 into the first screw hole 403 and the second screw hole 404 at the same time, when the length of the support rod 4 needs to be changed, the second screw holes 404 at different height positions are selected to be matched with the first screw holes 403, and the structure is simple and convenient to use.

In this embodiment, the bracket 201 and the support frame 5 are fixed to the bottom frame 104 by welding. The welding fixing mode is simple, and the structure is firm.

Finally, in this embodiment, the roller units 2 and the supporting units 3 are both disposed at the bottom of the bottom frame 104, so that the overall appearance of the door frame is not affected, and the door frame does not occupy other positions, thereby reducing the occupied space of the door frame as much as possible.

In some other embodiments, if the door frame 1 is closer to the ground, the roller units 2 and the supporting units 3 may be disposed on the side wall of the door frame 1, so as to facilitate installation and detachment by a constructor.

Although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the following descriptions are only provided for illustrating the technical solutions of the present invention and not for limiting the same: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
