Detailed Description
Preferred embodiments of the present utility model will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the adjustable support device for a civil air defense door according to a preferred embodiment of the present utility model includes a hinge base 1, a connection bolt 2, a door frame assembly 3, and an adjustment assembly 4, wherein the hinge base 1 is mounted on the door frame assembly 3 through the connection bolt 2, and the adjustment assembly 4 is mounted on the door frame assembly 3 to act on the hinge base 1 for coaxiality adjustment and shear protection.
In the present embodiment, the coupling bolts 2 are two rows of coupling bolts, which respectively couple and fix the hinge support 1 to the door frame assembly 3 at both left and right sides of the hinge support 1. In fig. 1, each row of tie bolts has four. It should be understood that the location and number of the connection bolts may be adjusted as desired.
In the present embodiment, the door frame assembly 3 includes a door frame 31 and a hinge mount plate 32, wherein the hinge mount plate 32 is welded to the door frame 31, and the hinge mount 1 is fixedly coupled to the hinge mount plate 32 by a coupling bolt 2, thereby transmitting the force received by the hinge mount 1 to the door frame wall.
In the present embodiment, the door frame assembly 3 further includes a right baffle 33 (i.e., a first baffle) and a lower baffle 34 (i.e., a second baffle), wherein the right baffle 33 is welded and fixed to the hinge mount plate 32 at the right side of the hinge mount 1, and the lower baffle 34 is welded and fixed to the hinge mount plate 32 below the hinge mount 1.
In this embodiment, the adjusting assembly 4 includes a right adjusting bolt 41 (i.e. a first adjusting bolt) and a lower adjusting bolt 42 (i.e. a second adjusting bolt), wherein the right adjusting bolt 41 passes through the right baffle 33 to be propped against the right side of the hinge seat 1 so as to adjust the coaxiality of the hinge seat 1 in the vertical direction, and the lower adjusting bolt 42 passes through the lower baffle 34 to be propped against the lower side of the hinge seat 1 so as to reliably support the vertical stress of the hinge seat 1, thereby avoiding the shearing damage of the connecting bolt 2 caused by overlarge stress and playing a role of protecting the connecting bolt 2 from shearing.
In this embodiment, the baffles 33, 34 are provided with threaded holes into which the adjusting bolts 41, 42 are screwed. In fig. 1, the right baffle 33 is provided with two threaded holes into which two right adjusting bolts 41 are screwed to be mounted so as to abut against the right outer surface of the hinge base 1; the lower baffle 34 is provided with two threaded holes into which two lower adjusting bolts 42 are screwed to be mounted so as to be abutted against the lower outer surface of the hinge support 1. The tightening position is as close as possible to the vertical line of bolting, as the installation conditions allow.
In this way, there is no need to plug the adjusting pad between the right baffle 33 and the hinge support 1 and between the lower baffle 34 and the hinge support 1, thereby fundamentally solving the defect of complicated procedures during the installation and debugging of the existing hinge.
In a word, the utility model starts from the use function, selects the adjusting bolts 41 and 42 with the resistance grade meeting according to the weight of the door leaf, and converts the complex operation of adjusting the hinged support by the original field multiple-time plug adjusting pad into the reliable support by only rotating the adjusting bolts 41 and 42 and tightly propping the adjusting bolts 41 and 42 with the hinged support 1 through the matching of the bolts and the threaded holes, thereby being convenient and quick. Meanwhile, the adjusting accuracy of the adjusting bolts 41 and 42 is higher, and the distance required to be jacked is mainly controlled by the number of screwing turns. The precision of the original plug adjusting pad can only be controlled to be more than 1mm (the minimum thickness of the gasket is 1 mm), and a plurality of gaps smaller than 1mm can only be formed by knocking and the like, so that the precision is difficult to ensure.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the scope of the present utility model, and various modifications can be made to the above-described embodiment of the present utility model. All simple, equivalent changes and modifications made in accordance with the claims and the specification of this application fall within the scope of the patent claims. The present utility model is not described in detail in the conventional art.
