Detailed Description
In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings and the detailed description.
A lower hinge assembly of a top-bottom hinge as shown in fig. 1 to 5 includes a base 1 capable of being mounted on a door pocket, and a mounting base 2 capable of being mounted on a door leaf. The top-bottom hinge is composed of a lower hinge component and an upper hinge component, wherein the upper hinge component is of a conventional structure (namely, the top-bottom hinge comprises an upper base fixed on the upper part of a door pocket and an upper mounting seat fixed on the top of a door leaf, the upper base is in a corner bracket shape, an upper shaft hole is formed in the upper base, an upper rotating shaft is arranged on the upper mounting seat, and the upper rotating shaft and the upper shaft hole are mutually matched).
More specifically, as shown in fig. 1, the base 1 includes a vertical plate 11 which can be fixed to the lower portion of the door pocket, and a horizontal plate 12 which is provided on one side of the lower portion of the vertical plate 11 and can be abutted against the ground. Typically, the vertical plate 11 is fixed to the lower end of the door pocket by screws. The bottom surface of the horizontal plate 12 is directly abutted with the ground, and the horizontal plate 12 and the vertical plate 11 form an L-shaped corner brace. More specifically, the horizontal plate 12 and the vertical plate 11 are integrally connected. Of course, the horizontal plate 12 and the vertical plate 11 can be regarded as corner brackets (i.e. the base 1) formed by bending a whole plate, and the forming is relatively simple.
As shown in fig. 2-5, the bottom surface of the horizontal plate 12 is provided with a containing groove 121 with a downward opening, an adjusting block 3 capable of moving in the containing groove 121 and abutting against the ground is arranged in the containing groove, and a locking structure is arranged between the adjusting block 3 and the horizontal plate 12. Of course, the adjusting block 3 is provided with a shaft hole 31, and the mounting seat 2 is provided with a rotating shaft 21 which can be matched with the shaft hole 31. Namely, the mounting seat 2 and the adjusting block 3 are rotatably connected through the rotating shaft 21 and the shaft hole 31.
In the utility model, when the door leaf and the door sleeve have errors, the gap can be directly adjusted without detaching the door leaf. The door leaf and the mounting seat 2 are turned aside, and then the locking structure (described in detail below) is loosened, so that the position of the adjusting block 3, that is, the size of the door gap, can be adjusted. After the adjustment, the locking structure is locked.
It is noted that the adjustment block 3 is smaller in size than the accommodation groove 121 in terms of size, and is movable in any horizontal direction in the accommodation groove 121. Of course, the boss 32 hereinafter is smaller in size than the through-hole 123 in the same manner, and can move in any horizontal direction in the through-hole 123. The degree of freedom of adjustment is thus relatively high, and is not limited to a single direction (described later).
The present utility model limits the movable range of the adjustment block 3 by means of the ground, using the co-engagement of the receiving groove 121 and the ground. In addition, in the utility model, the size of the accommodating groove 121 is only required to be larger than that of the adjusting block 3, and the adjusting block 3 can move in the accommodating groove 121 without considering the size error of the adjusting block 3, so that the accuracy requirements on the adjusting block 3 and the accommodating groove 121 are not high, and the cost is reduced.
In the present utility model, since the adjusting block 3 is directly abutted against the ground, the horizontal plate 12 is not directly forced, and the gravity of the door leaf acts on the adjusting block 3 and is directly transmitted to the ground, the horizontal plate 12 only plays a limiting role (the limiting role here means the receiving groove 121 thereon, and the through hole 123 described later). Thus, the horizontal plate 12 is not stressed, is not easy to deform and damage, and is durable.
More specifically, the locking structure includes a plurality of threaded holes 122 formed on the upper surface of the horizontal plate 12 and penetrating the receiving groove 121, and a top thread 4 formed in the threaded holes 122 and capable of pressing down the adjusting block 3.
In the utility model, the size of the door gap is convenient to adjust. Specifically, when the adjusting block 3 is to be locked, only the jackscrew 4 needs to be screwed down, the jackscrew 4 can downwards push the adjusting block 3, and the adjusting block 3 is tightly pushed on the ground, so that the adjusting block 3 is locked. If the position of the adjusting block 3 is to be adjusted, the mounting seat 2 (the mounting seat 2 is provided with a door leaf, and the door leaf does not need to be disassembled) is turned to one side, so that the threaded hole 122 and the jackscrew 4 are completely exposed, at this time, the jackscrew 4 can be rotated by tools such as a screwdriver, and the like, the position of the adjusting block 3 can be adjusted by loosening the jackscrew 4, and after the adjustment is completed, the jackscrew 4 is locked.
It is worth noting that the jackscrew 4 of the present utility model is used for pressing the adjusting block 3 from top to bottom onto the ground so as to lock the adjusting block 3, and the adjusting block 3 is also subjected to the gravity of the door leaf, and the gravity of the door leaf helps to strengthen the locking of the jackscrew 4, i.e. the gravity of the door leaf makes the adjusting block 3 self-locking to a certain extent, so that the loosening of the adjusting block 3 can be avoided.
More specifically, the horizontal plate 12 is provided with a through hole 123, the adjusting block 3 is provided with a boss 32, the shaft hole 31 is provided on the boss 32, and the boss 32 is inserted into the through hole 123 from bottom to top and can move in the through hole 123. Further, the cross-sectional dimension of the through hole 123 is larger than the cross-sectional dimension of the boss 32, and the boss 32 can move in any horizontal direction in the through hole 123. Of course, the through hole 123 can limit the boss 32, so that the boss 32 can be finely adjusted only within the range of the through hole 123 and cannot be freely separated.
In the utility model, the degree of freedom of adjustment is high. Specifically, as described below, when the jack screw 4 is released, the body of the adjusting block 3 can be moved forward and backward and leftward and rightward at random in the accommodating groove 121, and the boss 32 can be moved forward and backward and leftward and rightward at random in the through hole 123, so that the degree of freedom of movement of the adjusting block 3 is high. Therefore, the door leaf can be subjected to position adjustment in at least a plurality of directions, namely front, back, left and right, and the door leaf is not limited to one direction, and the door gap can be adjusted smoothly and conveniently.
More specifically, the mounting base 2 is rectangular plate-shaped, and the rotating shaft 21 is disposed at a corner portion of the bottom surface of the mounting base 2. Namely, the rotating shaft 21 is arranged at one corner position (shown in fig. 2) of the bottom surface of the mounting seat 2, so that when the mounting seat 2 rotates around the rotating shaft 21 to a certain position (shown in fig. 4), the threaded hole 122 and the jackscrew 4 can be completely exposed, and the jackscrew 4 can be disassembled and adjusted by using a tool (such as a screwdriver).
More specifically, the mounting base 2 is provided with a plurality of strip-shaped holes 22. The mounting seat 2 and the door leaf are connected by a plurality of screws which pass through the corresponding strip-shaped holes 22 so as to adjust the position of the mounting seat 2 during installation.
