Description
Technical Field
[0001] The utility model relates to the technical field of rolling shutter door installation, in particular to an adjustable bracket for a large rolling shutter door. Background Art
[0002] The rolling door includes a motor for controlling the rotation of the roller and a bracket for fixing the motor. A conventional motor housing is provided with three circular holes, and the center points of the three circular holes are cocircular. When the motor and the bracket are installed, a plurality of connecting columns on the bracket respectively pass through the corresponding holes on the motor housing, and the outer ends of the connecting columns are threadedly connected with nuts, and the nuts abut against the end faces of the holes on the motor housing to install the motor on the bracket.
[0003] Due to equipment precision, process control or human factors, there is a certain deviation in the position of the connecting column on the bracket, which causes the connecting column on the bracket to be incompatible with the round hole on the motor. In order to improve the compatibility of the motor and the bracket, facilitate the installation of the motor on the bracket, and quickly align the connecting column with the hole, the hole on the motor casing has to be set from a round hole to a strip hole. When the hole on the motor casing is a strip hole and is used on a large rolling door, the motor vibrates during operation. Since the length of the strip opening in the strip hole is greater than the diameter of the connecting column, a larger degree of freedom is provided for the connecting column. The relative position of the connecting column and the strip hole is prone to change, or the connecting column is tilted, which in turn causes the motor to shake or be unstable during operation, which in turn causes the large rolling door to shake or get stuck during operation. Due to the large size and heavy weight of large rolling doors, they are often used in commercial places, warehouses, factories and other places. Shaking or getting stuck during operation of large rolling doors is more likely to cause safety hazards, such as the inability of large rolling doors to operate normally, hindering the control of fire and increasing the risk of fire.

[0009] Compared with the prior art, the beneficial effects of the present invention are:
[0010] The adjustment component of the utility model can adjust the two second connecting columns at the same time, so that the two second connecting columns move radially along the first base, thereby ensuring that the first connecting column and the two second connecting columns can adjust their positions as needed and align with the circular holes on the motor, so that the bracket is adapted to the motor with the circular holes, reducing the difficulty of installation, facilitating the connection between the motor and the bracket, ensuring that the motor and the bracket are stably connected, and thus ensuring that the large rolling door runs smoothly and safely.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0026] The reference numerals include: bracket body 1, first base 2, connecting assembly 3, first connecting column 301, second connecting column 302, adjusting assembly 4, slider 401, first dovetail groove 402, second dovetail groove 403, first dovetail block 404, second dovetail block 405, second base 406, threaded hole 4061, connecting rod 407, handle 4071.
[0027] like Figure 1-3 As shown, an adjustable bracket for a large rolling door includes a bracket body 1, and the bracket body 1 is provided with a first base 2 and a second base 406. In this embodiment, the first base 2 is a round block, and the first base 2 is provided with a connecting component 3 for connecting a motor and an adjusting component 4 for simultaneously adjusting the positions of two second connecting columns 302. The connecting component 3 includes a first connecting column 301 fixedly connected to the first base 2 and two second connecting columns 302 that can be adjusted and positioned along the radial position of the first base 2.
[0028] The adjustment component 4 includes a slider 401, a first dovetail groove 402, two second dovetail grooves 403, a first dovetail block 404 slidingly matched with the first dovetail groove 402, a second dovetail block 405 slidingly matched with the second dovetail groove 403, a second base 406 and a connecting rod 407. The slider 401 is connected to the first dovetail block 404. The center line of the first dovetail groove 402 in the width direction and the center point of the connection between the first connecting column 301 and the first base 2 are located in the radial direction of the first base 2. The first dovetail groove 402 and the two second dovetail grooves 403 are all located on the first base 2 and are arranged at intervals along the circumference of the first base 2. The two second dovetail grooves 403 are symmetrically distributed on both sides of the first dovetail groove 402. The second dovetail block 405 is connected to the corresponding second connecting column 302. Both ends of the slider 401 pass through the second dovetail block 405 respectively, and the slider 401 is slidingly matched with the second dovetail block 405.
[0029] In this embodiment, the slider 401 includes a first connecting block and a second connecting block located at both ends of the first connecting block. The angle between the first connecting block and the second connecting block is an obtuse angle (the angle range is greater than 90 degrees and less than 180 degrees). The second connecting block passes through the second dovetail block 405 and slides with the second dovetail block 405. The first dovetail block 404 and the second dovetail block 405 have the same shape. The first dovetail block 404 includes a first connecting portion and a second connecting portion. The first connecting portion and the second connecting portion are connected. The first connecting portion is in contact with the surface of the first base 2, and the second connecting portion is slideably matched with the first dovetail groove 402. The surface of the first connecting portion opposite to the first base 2 and the end surface of the first base 2 are provided with anti-slip stripes.
[0030] The second base 406 is located on one side of the first base 2 and is fixedly connected to the bracket body 1. In this embodiment, the second base 406 is a support block. The second base 406 is provided with a threaded hole 4061. One end of the connecting rod 407 passes through the threaded hole 4061 and is rotatably connected to the first dovetail block 404. The connecting rod 407 is threadedly connected to the threaded hole 4061, and a handle 4071 is provided at the outer end of the connecting rod 407.
[0031] Principle and specific operation steps of adjusting the second connecting column 302:
[0032] Since the center points of the three circular holes on the motor housing are cocircular, when one of the circular holes on the motor is aligned with the first connecting post 301, it is only necessary to adjust the positions of the two second connecting posts 302 according to the positions of the remaining two circular holes on the motor, so that the first connecting post 301 and the two second connecting posts 302 can be aligned with the corresponding circular holes;
[0033] The handle 4071 is held and rotated, and the connecting rod 407 is driven to rotate through the handle 4071. The connecting rod 407 rotates and cooperates with the threaded hole 4061 on the second base 406, and the connecting rod 407 moves along the length direction of the first dovetail groove 4022. When the connecting rod 407 moves, the first dovetail block 404 is driven to slide and cooperate with the first dovetail groove 402. The first dovetail block 404 moves along the length direction of the first dovetail groove 402. Since the first dovetail block 404 is connected to the first connecting block on the slider 401, the slider 401 is also driven to move along the length direction of the first dovetail groove 402 when the first dovetail block 404 moves. Since the second connecting blocks on the slider 401 all pass through the corresponding second dovetail blocks 405 and slide and cooperate with the second dovetail blocks 405, since the first connecting block on the slider 401 is connected to the second connecting block The angle between the blocks is an obtuse angle. When the slider 401 moves along the length direction of the first dovetail groove 402, the slider 401 simultaneously drives the two second dovetail blocks 405 to slide and cooperate with the corresponding second dovetail grooves 403, and move radially along the first base 2. Since the second connecting column 302 is connected to the second dovetail block 405, the second dovetail block 405 moves while driving the corresponding second connecting column 302 to move, so as to adjust the position of the two second connecting columns 302 at the same time, so that the first connecting column 301 and the two second connecting columns 302 are aligned with the circular holes on the motor housing. Since the connecting rod 407 is threadedly connected to the second base 406, when the connecting rod 407 stops rotating, the position of the connecting rod 407 is automatically limited, and the positions of the second dovetail block 405, the slider 401, the second dovetail block 404 and the second connecting column 302 are limited in turn.
[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
