Description

Technical Field

[0001] The utility model relates to the technical field of existing door and window detection, in particular to a static load pressurizing device for existing doors and windows. Background Art

[0002] Existing doors and windows refer to doors and windows that have been installed and are in use in a building. These doors and windows may have been used for a period of time and have experienced daily use and the impact of the natural environment, so their performance and usage conditions may be different from those of newly installed doors and windows. When existing doors and windows have been used for a long time, it is necessary to use the existing door and window static load pressurization device to pressurize the existing doors and windows to test the performance of the doors and windows under a certain static load pressure, so as to evaluate the structural strength, sealing performance and durability of the doors and windows.

[0003] After searching, the utility model patent with Chinese patent announcement number CN207215579U discloses a static load pressurizing device for the exterior wall of existing doors and windows, including a mounting bracket, an electric telescopic rod, a pressure value display, a displacement value display, a pressure sensor, a movable rod, a displacement sensor and a fixing component. The electric telescopic rod is installed on the outer side of the upper end of the mounting seat, and the outer surface of one side of the rear end of the control box is sequentially installed with a pressure value display and a displacement value display from top to bottom. The pressure sensor is installed on the outer side of the other end of the electric telescopic rod, and the movable rod is connected to one side of the pressure sensor. The displacement sensor is installed on the outside of one side of the movable rod, and a fixing component is installed on the outer side of one end of the second support rod. The utility model has a scientific and reasonable structure, is safe and convenient to use, and is provided with an electric telescopic rod as a driving device, which replaces the commonly used fan driving device. The noise can be reduced to a minimum or even no noise when detecting doors and windows, avoiding the problem of huge noise emitted by the fan drive. The operation is simple and easy to use.

[0004] After searching the above patent, it was found that the pressure detection of existing doors and windows was processed. However, when the device performs pressure detection on existing doors and windows, it is necessary to first fix the bracket on the wall before the pressure detection on the existing doors and windows can be performed. When the height of the installed existing doors and windows is high, it takes more manpower to fix the bracket on the wall, which makes the operation cumbersome and inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide a static load pressurizing device for existing doors and windows, which can facilitate pressurizing detection of existing doors and windows of different heights, so as to solve the problem in the prior art that it is inconvenient to perform pressurizing detection on existing doors and windows of different heights.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An existing static load pressurizing device for doors and windows comprises a base, a plurality of universal wheels are fixedly connected to the lower end of the base, a shell is slidably connected to the upper end of the base, an electric push rod is fixedly connected to the inside of the shell, a column is fixedly connected to the output end of the electric push rod, a pressure sensor is fixedly connected to the inside of the column, a movable column is slidably connected to the side wall of the column, and the end of the movable column cooperates with the pressure sensor; a movable plate, the movable plate is arranged inside the shell, a plurality of suction cups are fixedly connected to the side wall of the movable plate, and the movable column and the column are both slidably connected to the movable plate.

[0008] Preferably, a hydraulic cylinder is fixedly connected inside the base, an output end of the hydraulic cylinder is slidably connected to an upper end of the base, and a lower end of the housing is fixedly connected to the output end of the hydraulic cylinder.

[0009] Preferably, a plurality of notches are provided at the upper end of the base, a plurality of auxiliary rods are fixedly connected to the lower end of the shell, and the auxiliary rods are slidably connected to the notches.

[0010] Preferably, a push rod is fixedly connected to the side wall of the base, and a rubber protective sleeve is fixedly connected to the side wall of the push rod.

[0011] Preferably, the column side wall is provided with a slide groove, the movable column is slidably connected to the slide groove, a spring is fixedly connected between the end of the movable column and the inner wall of the slide groove, and the pressure sensor side wall is fixedly connected to the inner wall of the slide groove.

[0012] Preferably, a fixed plate is passed through and fixedly connected to the side wall of the column, and a second spring is fixedly connected between the side wall of the fixed plate and the side wall of the movable plate.

[0013] Compared with the prior art, the advantages of the utility model are:

[0014] 1. The operator pushes the push rod to make the universal wheel roll and moves the entire device to the specified position, then locks the universal wheel. The operator then wipes the surface of the door and window frame to prevent foreign matter and dust from existing on the surface of the door and window frame, and pushes the shell through the hydraulic cylinder to move the shell upward. After the shell moves upward to an appropriate height, the electric push rod pushes the column to one side of the door and window frame, so that one end of the movable column fits the surface of the door and window frame. The electric push rod continues to pressurize and extend, so that the other end of the movable column contacts the pressure sensor. The pressure sensor transmits the data of the pressure borne by the door and window frame to the display screen for display, so that the operator can record the data, so that the device can perform pressurized detection on existing doors and windows of different heights.

[0015] 2. When one side of the movable column is fitted with the surface of the door and window frame, the movable plate is pushed by the fixed plate and the spring, so that the movable plate drives the suction cup to fit with the surface of the door and window frame first, so that the suction cup adsorbs the door and window frame, thereby fixing the door and window frame at a fixed point. Then the movable column passes through the movable plate and fits with the side wall of the door and window frame to avoid the device from shifting when the door and window frame is pressure tested, resulting in inaccurate pressure test data.
