Hydraulic system for student dormitory windows

[0014] The following are specific embodiments of the present invention combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0015] Such as figure 1 with figure 2 As shown, the dormitory building includes a wall 1 and a window frame 2 located on the outside of the wall 1. It is characterized in that the windows of this dormitory include a protective net 31 located on the outside of the window frame 2, and the protective net 31 is fixed to a rectangular installation frame 32 Inside, the two outer sides of the mounting frame 32 are respectively provided with a sliding groove 33, two brackets 34 respectively located on both sides of the mounting frame 32 are fixedly provided on the wall body 1, and two connecting rods are hinged on each bracket 34 The middle part of the connecting rod is hinged with the mounting frame 32, and the outer end of the connecting rod is fixedly provided with a sliding block 35 which is slidably connected in the sliding groove 33. The windows of this dormitory also include two double-acting hydraulic cylinders 4, which are located in The inner ends of the two connecting rods on one side of the mounting frame 32 are respectively connected with the two piston rods of the hydraulic cylinder-4. The cylinder body of the hydraulic cylinder-4 is fixed in the wall 1. The lower end of the mounting frame 32 has a bearing plate 5. , The protective net 31 located on the outside of the window frame 2 can effectively prevent the occurrence of window throwing and students committing suicide; in the event of a fire hazard in the student dormitory, it can control the two piston rods of the hydraulic cylinder 4 of the dormitory window to contract, so The connecting rods on both sides of the mounting frame 32 shrink to drive the mounting frame 32 to move to the outside of the window frame 2. In this way, the bearing plate 5, the protective net 31 and multiple connecting rods form a space that can accommodate students. Students only need to open it. The glass on the window frame 2 can be stepped on the carrying plate 5 for refuge.

[0016] Such as figure 2 with image 3 As shown, the windows of the dormitory also include two hydraulic hoses 61 and two single-acting hydraulic cylinders 62 corresponding to the hydraulic cylinder one 4 one by one. The two ends of the hydraulic hose 61 are connected to the hydraulic cylinder one 4 and the hydraulic cylinder two respectively. 62 is connected, the second hydraulic cylinder 62 is provided with a ball valve 63 capable of blocking the internal hydraulic passage of the second hydraulic cylinder 62, and a coil spring 64 under tension is connected between the inner ends of the two connecting rods on the same side of the mounting frame 32 A handle 65 is fixed on the piston rod of the second hydraulic cylinder 62. The normal state of the two piston rods of the hydraulic cylinder 4 is in the extended state. When the shelter outside the window frame 2 needs to be opened, the ball valve 63 arranged on the hydraulic cylinder 2 62 is rotated to make the hydraulic cylinder 2 62 communicate with the hydraulic cylinder 1 4 Under the action of the coil spring 64 and manpower, the hydraulic oil in the hydraulic cylinder 4 enters the hydraulic cylinder 2 62, so that the two piston rods of the hydraulic cylinder 4 are contracted, and the protective net 31 is moved to the outside of the window frame 2. , So as to provide students with a shelter space, after use, you can push the handle 65 on the hydraulic cylinder two 62, so that the hydraulic oil enters the hydraulic cylinder one 4, and make the two piston rods of the hydraulic cylinder one 4 in the extended state , And then close the ball valve 63; the hose 61 connected between the hydraulic cylinder one 4 and the hydraulic cylinder two 62 can facilitate the installation of the hydraulic cylinder one 4 and the hydraulic cylinder two 62 on the wall 1.

[0017] A window is equipped with two independent hydraulic control systems to prevent misoperation; the window installation frame 32 is controlled by a linkage structure and a hydraulic system, and does not involve an electronic structure, which can prevent the occurrence of power failure in the event of a fire. More effective.

[0018] Such as figure 2 As shown, a pallet 7 is fixedly provided on the outer side of the wall 1, and the bearing plate 5 is located above the pallet 7 and abuts the pallet 7. The mounting frame 32 and the bearing plate 5 themselves are difficult to bear the force, and need to be supported by the pallet 7 fixed on the wall 1.
