Description

Technical Field

[0001] This utility model relates to the field of door and window sealing technology, and more specifically, to a door and window sealing strip disassembly and assembly device. Background Technology

[0002] Sliding doors and windows are widely used. To ensure their sealing effect, sealing strips are installed in the grooves inside the frame. When these strips age and harden, they are prone to breakage during replacement. Once this happens, the base of the strip remains in the groove, making it difficult to remove completely. This hinders the smooth installation of new sealing strips, sometimes requiring physical damage to the frame for replacement. This significantly reduces the overall lifespan of the sliding doors and windows and decreases the efficiency of sealing strip replacement.

[0003] To address the aforementioned issues, patent document publication number CN211414971U discloses a door and window sealing strip replacement device, comprising a fixed base. The upper surface of the fixed base has a first slot and a second slot sequentially formed from left to right. A first connecting rod is fixedly installed at the left end of the fixed base, and a first roller is connected to the first connecting rod via a bearing.

[0004] However, in actual use, it still has some drawbacks. For example, the above-mentioned equipment requires frequent disassembly and reassembly of tools to switch according to actual needs, which increases the operation interruption time, affects the overall efficiency of rubber strip disassembly and reassembly, and reduces the practicality of the equipment to a certain extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a door and window sealing strip disassembly and assembly device to solve the problem that the prior art equipment requires frequent disassembly and assembly of tools during use, which affects the efficiency of sealing strip disassembly and assembly.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a door and window sealing strip disassembly and assembly device, including a fixed base, the door and window sealing strip disassembly and assembly device further including a fixed shaft, the fixed shaft being disposed on the top of the fixed base, the fixed shaft being configured as a hollow structure;

[0007] A threaded rod is rotatably mounted inside a fixed shaft, and a handwheel is fixedly connected to the top end of the threaded rod;

[0008] A movable column is threaded onto the surface of a threaded rod, and the surface of the movable column is slidably connected to the inner wall of a fixed shaft.

[0009] Connecting seat one, the connecting seat one is fixedly installed at the bottom end of the movable column, the mounting column is rotatably installed inside the connecting seat one, and the two sides of the surface of the mounting column are provided with fitting rings opposite each other, the surface of the fitting rings is fitted with the side of the connecting seat one;

[0010] A connecting frame one, the top end of which is fixedly connected to the surface of the mounting column end, and a connecting seat two is fixedly installed at the bottom end of the connecting frame one, with a scraper provided at the bottom of the connecting seat two;

[0011] The second connecting frame is fixedly connected to the surface of the end of the mounting column on one side, and a pressure roller is provided on the side of the second connecting frame opposite to the mounting column.

[0012] It also includes cross-shaped grooves, which are formed opposite to each other on both sides of the mounting post.

[0013] The connecting seat has mounting brackets on both sides of its top. A spring is fixedly connected to the inner wall of the mounting bracket. A movable seat is fixedly connected to one end of the spring relative to the mounting bracket. The side of the movable seat is slidably connected to the inner wall of the mounting bracket. A snap-fit ​​plate is fixedly installed on the bottom surface of the movable seat. The surface of the snap-fit ​​plate snaps into the inside of the cross-shaped groove.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] In the above scheme, by rotating the handwheel at the top of the threaded rod, the threaded rod rotates synchronously inside the fixed shaft. Since the outer wall of the movable column is slidably connected to the inner wall of the fixed shaft, the movable column can move vertically downward under the rotation of the threaded rod, thereby driving the pressure roller or scraper to approach the door and window rubber strip for processing. When it is necessary to switch the pressure roller or scraper, the mounting column in the connecting seat 1 is rotated 90 degrees so that the corresponding tool can face the door and window, thus completing the quick switching of tools. This replaces the process of disassembling and assembling tools, realizes the direct switching of the required tools, greatly shortens the operation interruption time, ensures the efficiency of rubber strip disassembly and assembly, and improves the practicality of the device.

[0016] When the mounting column rotates, the elastic structure of the spring in the mounting bracket drives the movable seat to move horizontally, causing the snap-fit ​​plate installed at the bottom of the movable seat to move synchronously and engage with the cross-shaped groove on the surface of the mounting column. This, combined with the friction generated between the rough surface structure of the fitting ring and the connecting seat, further secures the mounting column and prevents the friction-increasing effect of the rough surface structure from decreasing after long-term use, thus affecting the stability of the mounting column after rotation.
