Description

Technical Field

[0001] The utility model relates to the technical field of building hardware tools, in particular to a device for replacing door and window sealing strips. Background Art

[0002] Door and window seals play a vital role in our daily lives. They effectively block the intrusion of wind, rain, dust, and noise, improving the sealing and thermal insulation performance of doors and windows. However, over time and with increased frequency of use, door and window seals gradually age and become damaged.

[0003] Currently, when door and window sealing strips need to be replaced, dismantling workers will use a blade to slide off the old sealing strips and then tear them off by hand. This makes it easy to scratch the glass when the blade cuts the door and window sealing strips, and also makes it easy for the sealing strips to remain on the door and window frames, affecting the subsequent installation of the door and window sealing strips. Therefore, we propose a door and window sealing strip replacement device to solve the above problems. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 A door and window sealing strip replacement device includes a fixed plate 1, a puncture mechanism is provided at the bottom of the fixed plate 1; the puncture mechanism includes two puncture tubes 2 fixed at the bottom of the fixed plate 1, and a sharp cone block 3 is fixed at the end of the puncture tube 2.

[0024] It is further explained that the two puncture tubes 2 at the bottom of the fixed plate 1 and the sharp cone block 3 at the end of the puncture mechanism can easily pierce the old sealing strip, providing a quick and effective entry point for replacing the sealing strip, greatly improving the efficiency of replacing the sealing strip, and eliminating the need to manually remove the old sealing strip, saving time and manpower.

[0025] like Figure 1 As shown, a protective sleeve 14 is fixedly sleeved on the puncture tube 2.

[0026] To further illustrate, the protective sleeve 14 can make the puncture tube 2 more stable when puncturing the old sealing strip.

[0027] like Figure 3 As shown, two puncture tubes 2 are arranged in parallel at the bottom of the fixing plate 1.

[0028] It is further explained that the purpose of such a setting is to enable puncture to be performed more smoothly during operation, improve the accuracy and controllability of the operation, and also make it easier for the user to hold the fixing plate 1 with both hands to better control the force and direction.

[0029] like Figure 1 and Figure 2 As shown, a limiting mechanism is provided on the puncture tube 2, and the limiting mechanism includes a fixed cavity 4 opened in the fixed plate 1 and connected to the puncture tube 2, an inverted T-shaped rod 5 is slidably provided on the inner wall of the fixed cavity 4, and two movable rods 6 are fixed to the bottom of the inverted T-shaped rod 5, and the outer wall of the movable rod 6 is slidably connected to the inner wall of the puncture tube 2, and two sliding holes 7 are opened on the puncture tube 2, and a limiting bolt 8 is slidably provided on the inner wall of the sliding hole 7.

[0030] The two limit bolts 8 are connected by multiple connecting springs 9. The two ends of the connecting springs 9 are fixedly connected to the outer walls of the two limit bolts 8. The ends of the two limit bolts 8 close to each other are provided with sliding grooves 10. The end of the moving rod 6 is fixed with an extrusion plate 11, and the outer wall of the extrusion plate 11 and the inner walls of the two sliding grooves 10 are both slidably connected.

[0031] Further explanation: in the limiting mechanism, when the puncture tube 2 penetrates the sealing strip, the cooperation of the inverted T-shaped rod 5, the movable rod 6 and the extrusion plate 11 can make the limiting bolt 8 extend from the sliding hole 7 of the puncture tube 2, clamping the sealing strip, preventing the puncture tube 2 from accidentally sliding out during the replacement process, thereby ensuring the stability and continuity of the replacement operation.

[0032] like Figure 1 As shown, a through hole communicating with the fixed cavity 4 is opened on the top of the fixed plate 1, the outer wall of the inverted T-shaped rod 5 and the inner wall of the through hole are slidably connected, a top plate 12 is fixed on the top of the inverted T-shaped rod 5, and a reset spring 13 is sleeved on the inverted T-shaped rod 5.

[0033] It is further explained that the top plate 12 on the top of the inverted T-shaped rod 5 is convenient for users to press and operate, and the reset spring 13 mounted on the inverted T-shaped rod 5 can automatically reset the device after the operation is completed, preparing for the next operation, thereby improving the convenience of using the device.

[0034] like Figure 2 As shown, the width of the extruded plate 11 gradually decreases from top to bottom.

[0035] It is further explained that the purpose of such a design is to enable the movable rod 6 to slide more smoothly in the slide groove 10 under the push of the movable rod 6, thereby accurately controlling the extension and retraction of the limit bolt 8 and ensuring the reliability of the limit function.

[0036] The functional principle of this utility model can be explained through the following operation modes:

[0037] 1. Puncture the old sealing strip

[0038] When the user uses the device to replace the door and window sealing strips, he holds the fixing plate 1 with both hands, aligns the two puncture tubes 2 with the old sealing strip that needs to be replaced, and punctures it with force: apply pressure steadily so that the sharp cone block 3 at the end of the puncture tube 2 pierces the old sealing strip. The design of the sharp cone block 3 can penetrate the sealing strip relatively easily.

[0039] 2. Start limit mechanism

[0040] After the puncture tube 2 successfully penetrates the sealing strip, press the top plate 12 on the top of the inverted T-shaped rod 5 with your finger to push the stop pin 8, causing the inverted T-shaped rod 5 to move downward, driving the bottom movable rod 6 downward. During the downward movement, the extrusion plate 11 at the end of the movable rod 6, due to its design of gradually decreasing width from top to bottom, gradually squeezes the sliding grooves 10 at the ends of the two stop pins 8 that are close to each other, causing the stop pins 8 to extend from the sliding hole 7 of the puncture tube 2. The extended stop pins 8 will clamp the sealing strip, preventing the puncture tube 2 from accidentally sliding out during the replacement process.

[0041] 3. Remove the sealing strip

[0042] After the stop bolt 8 has clamped the sealing strip, gently pull the device to remove the old sealing strip from the door and window. Due to the fixing effect of the puncture tube 2 and the stop bolt 8, the old sealing strip can be removed relatively easily without breaking or remaining.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
