For those of ordinary skill in the art, the specific meanings of the above terms in the invention can be understood in specific situations.

With reference to FIGS. 1 to 3 , an embodiment of the present invention provides an angle-adjustable connection device, which includes a bracket assembly 2, a first support 1-1 and a second support 1-2; the bracket assembly 2 Including a screw 2-5 and a first bracket 2-1, a second bracket 2-2, a third bracket 2-3 and a fourth bracket 2-4 hinged end to end, the first bracket 2-1 and the second bracket 2- The side walls of the hinge shafts of One end of 5 passes through the first threaded hole, and the other end passes through the through hole and is connected to the first limiting part; the hinge shafts of the second bracket 2-2 and the third bracket 2-3 are hinged with the first support 1-1 , the hinge shafts of the first bracket 2-1 and the fourth bracket 2-4 are used for hinged connection with one end of the equipment to be installed, and the second support 1-2 is used for hinged connection with the other end of the equipment to be installed. The device to be installed may be, but not limited to, the communication device 3 .

The following takes the communication device 3 as an example to describe the operation method of the angle-adjustable connection device of this embodiment: For the convenience of description, the hinge shafts of the first bracket 2-1 and the second bracket 2-2 may be referred to as upper hinge shafts 2-6, the hinge axis of the second bracket 2-2 and the third bracket 2-3 can be referred to as the right hinge axis 2-7, and the hinge axis of the third bracket 2-3 and the fourth bracket 2-4 can be referred to as the lower The hinge shaft 2-8, the hinge column of the fourth bracket 2-4 and the first bracket 2-1 may be referred to as the left hinge shaft 2-9.

First, fix the first support 1-1 and the second support 1-2 on the fixing rod 4 or the wall in sequence from top to bottom; then, hinge the two ends of the communication device 3 to the left hinge shaft 2- 9 and the second support 1-2; finally, adjust the inclination angle of the communication device 3, specifically: when the inclination angle of the communication device 3 relative to the fixed rod 4 or the wall is to be increased, the staff only needs to turn the screw 2 counterclockwise -5 will do. During the process of rotating the screw 2-5, the upper hinge shaft 2-6 and the lower hinge shaft 2-8 move toward each other, that is to say, the distance between the upper hinge shaft 2-6 and the lower hinge shaft 2-8 gradually decreases, The distance between the left hinge shaft 2-9 and the right hinge shaft 2-7 gradually increases. At this time, the communication device 3 will rotate around its hinge axis with the second support 1-2 in a direction away from the fixing rod 4 or the wall surface. When the inclination of the communication device 3 relative to the fixed rod 4 or the wall is to be reduced, the staff only needs to turn the screws 2-5 clockwise. During the process of rotating the screw 2-5, the upper hinge shaft 2-6 and the lower hinge shaft 2-8 move back, that is to say, the distance between the upper hinge shaft 2-6 and the lower hinge shaft 2-8 gradually increases , the distance between the left hinge shaft 2-9 and the right hinge shaft 2-7 gradually decreases. At this time, the communication device 3 rotates toward the fixed rod 4 or the wall around the hinge axis between the communication device 3 and the second support 1-2. It should be noted that, in actual use, the moving direction of the upper hinge shaft 2-6 and the lower hinge shaft 2-8 can be adjusted by changing the thread direction of the screw rod 2-5 when the screw rod 2-5 rotates clockwise or counterclockwise.

It can be seen from the above that the device has a simple structure and is convenient to operate. When adjusting, the upper hinge shaft 2-6, that is, the hinge shaft of the first bracket 2-1 and the second bracket 2-2, can be driven to be hinged with the lower hinge only by rotating the screw 2-5. The shaft 2-8, that is, the hinge shafts of the third bracket 2-3 and the fourth bracket 2-4, move toward or away from each other, thereby increasing or decreasing the inclination of the device to be installed relative to the fixed rod 4 or the wall. It can be seen that there is no need to hold the equipment to be installed by hand during the whole adjustment process, and only one person can rotate the screw 2-5 to realize the adjustment of the inclination of the equipment to be installed and the self-locking of the bracket assembly 2, which greatly improves the convenience of operation and reduces the labor cost. cost. In addition, since the four brackets of the bracket assembly 2, namely the first bracket 2-1, the second bracket 2-2, the third bracket 2-3 and the fourth bracket 2-4 are hinged end to end in sequence, the four brackets can Supporting each other, on the premise of ensuring the strength of the bracket assembly 2, the strength requirements of each bracket are lower than the strength requirements of the existing brackets, that is to say, each bracket in this embodiment can be made of lightweight materials, and is made of This significantly reduces the weight of the entire device.

Preferably, the length of the screw 2-5 is greater than the sum of the lengths of the first bracket 2-1 and the fourth bracket 2-4, that is, the length of the screw 2-5 is longer than the distance between the head and tail of the first bracket 2-1 and the first bracket 2-1. The sum of the head and tail distances of the four brackets 2-4.

Preferably, the structures of the first bracket 2-1, the second bracket 2-2, the third bracket 2-3 and the fourth bracket 2-4 are the same, that is, the first bracket 2-1, the second bracket 2-4 2.
