[0017] The following description, in conjunction with the accompanying drawings of the embodiments of the present invention, will illustrate the embodiments of the present invention. The technical solutions described herein are clearly and completely provided. Obviously, the described embodiments are merely this. This describes some, but not all, embodiments of the utility model. Based on the present utility model... Examples of embodiments obtained by those skilled in the art without inventive effort. All other embodiments are within the scope of protection of this utility model.

[0018] In practical implementation: such as Figure 1-4 As shown, a quick-replacement machine for sealing strips of building doors and windows. The mechanical clamp includes: an upper clamping arm 100, a lower clamping arm 200, and a guide mechanism 400. The lower clamping arm 200... Hinged to the surface of the upper clamping arm 100, the opposite ends of the lower clamping arm 200 and the upper clamping arm 100 are both fixed. Connected with a pressure seat 300.

[0019] A rolling roller 500 is rotatably connected to the surface of the pressure base 300. The rolling roller 500 can effectively reduce... The friction between the low-pressure seat 300 and the sealing strip can not only reduce the friction between the upper pressure seat 300 and the sealing strip, but also reduce the friction between the upper pressure seat 300 and the sealing strip. This reduces the probability of the sealing strip being damaged by compression, and also reduces the impact on the lower pressure seat 300 and the sealing strip. This reduces the probability of the adhesive surfaces sticking together, thereby improving the efficiency of users installing sealing strips.

[0020] The surface of the lower clamping arm 200 is provided with a guide hole 210, which is located at the lower pressure. Between seat 300 and upper clamping arm 100, this allows for the directional guidance of the sealing strip to reduce the amount of sealant. The probability that the strip will tilt during installation.

[0021] Both the upper clamping arm 100 and the lower clamping arm 200 have resistance-increasing rings 600 fixedly connected to their surfaces to increase resistance. Ring 600 is a rubber component, which improves the user's operation of the upper clamping arm 100 and the lower clamping arm. The friction of 200 makes the installation of the sealing strip more stable.

[0022] When using this clamp, the two pressure seats 300 are first separated by rotating the lower clamping arm 200. Then, the end of the sealing strip is moved through the guide hole 210 between the two pressure seats 300, and Furthermore, the adhesive side of the sealing strip needs to face downwards towards the pressure seat 300, and then the guide mechanism 400... The corresponding guide plate 420 fits into the side of the door and window frame groove and the end of the sealing strip is then attached. Adhere it into the groove, then manually pull the upper clamp arm 100 degrees away from the end of the sealing strip, and clamp it. Arm 100 moves the upper pressure seat 300, pressing and sticking the sealing strip to the door and window during the movement. The grooves in the frame allow for quick and straight installation of the sealing strips.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the guide mechanism 400 includes a component rotatably connected to the upper clamping arm. A 100-degree surface-mounted bidirectional lead screw 410, with two opposite threads on the surface of the bidirectional lead screw 410. The water is connected to a guide plate 420, and the two guide plates 420 are symmetrically distributed on the upper pressure seat 300. The guide mechanism 400 on both sides not only helps the user press and stick the sealing strip flat, but also assists in the application. The corresponding position in the door and window frame groove, and the user can also refer to the door and window frame groove. The installation position of the adjustable sealing strip can be adjusted to accommodate different sizes of fixtures. The door and window frame recesses do not need to be custom-made according to the specifications of the door and window frame recesses, thus achieving... This expands the applicability of the fixture.

[0024] The guiding mechanism 400 also includes a guide rod 430 fixedly connected to the surface of the upper clamping arm 100. Both ends of the guide rod 430 extend to the outside of the two guide plates 420, respectively. The guide rod 430 and... The axes of the bidirectional lead screw 410 are parallel, which prevents the bidirectional lead screw 410 from driving the guide plate. 420 rotate together to ensure that the guide plate 420 can move smoothly.

[0025] One end of the bidirectional lead screw 410 is fixedly connected to an adjusting handle 440, and the adjusting handle 440... The edges and corners are rounded, which reduces the burden on the user when rotating the bidirectional leadscrew 410, and reduces... The difficulty of adjustment for users.

[0026] One end of the guide plate 420 is rotatably connected to a roller 450, and the roller 450 is connected to a bidirectional lead screw 410. The axes are parallel, which reduces the friction between the guide plate 420 and the groove contact surface, making... The user can easily move the entire clamp.

[0027] When using this invention, if the user needs to attach the sealing strip to the door or window frame... When the corresponding position in the groove is reached, the user only needs to rotate the bidirectional lead screw 410 in the corresponding direction. The lead screw 410 drives two guide plates 420 simultaneously via two opposite threads, following the guide rod. 430 moves towards or away from each other until the distance between the corresponding guide plate 420 and the pressure base 300 is... Continue until the side of the groove aligns with the adhesive strip's placement; at this point, the user can proceed with the corresponding guide. Plate 420 fits against the side of the groove, and then the entire clamp is moved along the side of the groove to seal it. The sealing strip is glued into the groove of the door and window frame, which allows the clamp to adapt to different door sizes. Window frame recesses do not require custom customization based on the specifications of door and window frame recesses, thus achieving expansion. This improves the applicability of the fixture.

[0028] It should be noted that the bidirectional lead screw 410 mentioned above is a relatively mature application of existing technology. The components are familiar, and the specific models can be selected according to actual needs, which will not be elaborated here.

[0029] Furthermore, it should be understood that although this specification describes embodiments, it is not... Each implementation contains only one independent technical solution; this narrative style in the specification is only... For clarity only, those skilled in the art should consider the specification as a whole, with each part distinct. The technical solutions in the examples can also be appropriately combined to form a combination that can be understood by those skilled in the art. Other implementation methods.
