[0012] Furthermore, a mounting groove is provided at the connection between the main cover plate and the handle, and the mounting groove is connected to the sliding cavity.

[0013] By adopting the above technical solution, the mounting groove can accommodate and load the handle.

[0014] Furthermore, a skid-resistant pad is bonded to the lower end of the handle, and the skid-resistant pad is made of rubber.

[0015] By adopting the above technical solution, the anti-slip limiting effect of the anti-slip pad is ensured to be stable.

[0016] Furthermore, a pressing seat is fixedly installed in the installation groove above the handle, and a top block is slidably connected to the lower end of the pressing seat.

[0017] By adopting the above technical solution, the top block can move downward under the action of the top pressure seat.

[0018] Furthermore, a chamber is provided in the pressing seat, and a spring is welded in the chamber of the pressing seat, wherein there are two springs which are symmetrically distributed.

[0019] By adopting the above technical solution, the spring can ensure that the driving effect of the top pressure seat on the top block is stable.

[0020] Furthermore, the spring is welded to the top block, and the top block is welded to the handle.

[0021] By adopting the above technical solution, it is ensured that the action force of the spring can be stably transmitted to the handle.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] The utility model provides a covering protection mechanism composed of a main cover plate, a left cover plate, a right cover plate, a sliding cavity, a roller, a lifting handle, an anti-slip pad and a top pressure seat, which can be quickly pulled out and fixed to adjust the length. During use, the door and window frame profile protection device can be applied to door and window frame profiles of different lengths, thereby improving the scope of application and flexibility of use of the protection device.

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] like Figure 1-Figure 7As shown, an adjustable door and window frame profile protection device in this embodiment includes a main cover plate 1, a left cover plate 2 and a right cover plate 3. The left cover plate 2 and the right cover plate 3 are located at both ends of the main cover plate 1 and are slidably connected to the main cover plate 1. A sliding cavity 4 is provided at the connection between the main cover plate 1 and the left cover plate 2 and the right cover plate 3. Rollers 5 are arranged at the lower ends of the left cover plate 2 and the right cover plate 3. Wheel rails 6 are provided at the corresponding positions of the main cover plate 1 and the rollers 5. The left cover plate 2 and the right cover plate 3 can perform smooth sliding adjustment operations under the action of the rollers 5 to ensure the adjustment effect of the door and window frame profile protection device.

[0035] The upper ends of the left cover plate 2 and the right cover plate 3 are both installed with a handle 7 on the side away from the main cover plate 1 by screws. The main cover plate 1 and the handle 7 are provided with grooves at the corresponding positions to accommodate the handle 7, thereby ensuring that the structural edges of the door and window frame profile protection device are flush; the four corners of the main cover plate 1 are all slidably connected with a handle 8, and the handle 8 is an inverted L-shape. The handle 8 can be conveniently held by the staff for easy control and management of the left cover plate 2 and the right cover plate 3.

[0036] An installation groove 9 is provided at the connection between the main cover plate 1 and the handle 8, and the installation groove 9 is connected to the sliding cavity 4, and the installation groove 9 can accommodate the top pressure seat 11; an anti-slip pad 10 is bonded to the lower end of the handle 8, and the anti-slip pad 10 is made of rubber to ensure that the anti-slip effect of the anti-slip pad 10 is good; a top pressure seat 11 is fixedly installed above the handle 8 in the installation groove 9, and a top block 13 is slidably connected to the lower end of the top pressure seat 11, and the top block 13 can move downward under the action of the top pressure seat 11; a chamber is provided in the top pressure seat 11, and a spring 12 is welded to the top pressure seat 11 in the chamber. There are two springs 12 and they are symmetrically distributed to ensure that the top pressure effect of the top pressure seat 11 is balanced; the spring 12 is welded to the top block 13, and the top block 13 is welded to the handle 8, so that the action of the spring 12 can be smoothly and stably transmitted to the handle 8.

[0037] The specific implementation process of this embodiment is as follows: when in use, the staff can cover the main cover plate 1 on the door and window frame profile, and then lift the handles 8 on both sides of the left cover plate 2 upwards so that the anti-slip pad 10 can be separated from the left cover plate 2, and then the staff can pull the left cover plate 2 to one side through the grip 7, so that the left cover plate 2 can slide out of the main cover plate 1 under the action of the roller 5, and after sliding to a suitable position, the staff can release the lifting of the handle 8, so that the handle 8 can move downward again under the action of the top pressure seat 11, and the anti-slip pad 10 can establish a close fitting relationship with the left cover plate 2, thereby producing an anti-slip limiting effect on the left cover plate 2 to prevent the left cover plate 2 from accidentally sliding, and then the staff can pull out the right cover plate 3 again according to the above steps, and simultaneously prevent and limit the sliding, so that the use of the door and window frame profile protection device can be more flexible, and the scope of application of the door and window frame profile protection device is improved.
