Detailed Description

Example 1

Referring to fig. 1-2, in this embodiment, a detachable simple portal frame includes a stand column 10, a cross beam 20 and a limiting block 30, wherein a connecting sleeve 11 is arranged at the top of the stand column 10, and a plurality of avoidance ports 13 are axially and alternately distributed on the connecting sleeve 11; the cross beam 20 is slidably arranged in the connecting sleeve 11 in a penetrating way, and a clamping groove 21 corresponding to the avoidance port 13 is formed in the peripheral surface of the cross beam 20; the limiting block 30 is clamped in the avoidance port 13, and the inner end of the limiting block 30 is clamped in the clamping groove 21.

The detachable simple portal frame of this embodiment optimizes current portal frame, has add the adapter sleeve 11 that has dodge mouthful 13, can be convenient for the quick assembly disassembly of crossbeam 20, and the stopper 30 of cooperation design can realize the locking of crossbeam 20 for the position of adapter sleeve 11 to improve overall structure's stability.

It should be noted that, in this embodiment, the two upright posts 10 are arranged parallel to each other, and the beam 20 sequentially passes through the connecting sleeves 11 at the top of the two upright posts 10, so as to form a portal hanger structure, and since the beam 20 is detachably penetrated into the connecting sleeves 11 as a whole, the detachment between the beam 20 and the upright posts 10 is more convenient, and the movement of the device after the whole detachment can be facilitated; the limiting block 30 is matched with the connecting sleeve 11 and the cross beam 20 in a plugging manner, so that the position of the cross beam 20 can be locked, and the stability of the whole structure of the device is improved.

In this embodiment, optionally, in order to improve structural stability of the upright 10, a base 14 horizontally placed is provided at the bottom of the upright 10, and meanwhile, by providing a diagonal brace 15 between the upright 10 and the base 14, structural strength of the upright 10 can be improved.

In addition, the connecting sleeve 11 is vertically arranged with the upright post 10 as a whole, in order to facilitate alignment of the positions of the clamping groove 21 and the avoidance port 13, a notch 12 extending along the axial direction is formed on the peripheral surface of the connecting sleeve 11, the avoidance port 13 is formed inside the notch 12, and the avoidance port 13 is symmetrically arranged at two sides of the notch 12 as an example.

In addition, the clamping groove 21 is integrally arranged along the radial direction of the cross beam 20, the limiting block 30 is provided with an arc-shaped end face matched with the appearance of the connecting sleeve 11, the limiting block 30 is integrally constructed into a fan shape, and when the limiting block 30 is clamped into the clamping groove 21 in the avoidance port 13, the arc-shaped end face of the limiting block 30 is flush with the peripheral surface of the connecting sleeve 11.

When the horizontal distance between the two vertical columns 10 (i.e., the distance between the two vertical columns 10) of the detachable simple portal frame needs to be adjusted, the limiting block 30 is firstly removed from the clamping groove 21, then the vertical columns 10 are moved to a proper position along the cross beam 20, the avoidance opening 13 at the position is ensured to correspond to the clamping groove 21, and finally the limiting block 30 is inserted into the clamping groove 21 again, so that the adjustment work is completed.

Although embodiments of the present application have been shown and described above, it should be understood that the above embodiments are illustrative and not to be construed as limiting the application, and that variations, modifications, alternatives, and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the application.
