Description

Technical Field

[0001] This invention relates to the technical field of building construction tools, and in particular to a compaction tool for window frame sealant. Background Technology

[0002] In window installation, after the window frame is installed, weather-resistant sealant (such as silicone sealant or expanding foam) needs to be injected into the gap between the window frame and the wall (generally 8-15mm wide). After it dries, it should be compacted to achieve a preliminary sealing and seepage prevention effect. According to the seepage prevention requirements, the weather-resistant sealant that overflows from the window frame should be squeezed down to slightly below the surface of the window frame after it dries to ensure that it is dense.

[0003] However, in this step of the construction process, the common practice now is for workers to cut or tear off the overflowing weather-resistant sealant or foam sealant and use their fingers to compact the sealant. This operation is difficult to achieve a sealing effect. For tall or irregularly shaped window frames, the operation space is limited, making it even more difficult to achieve the desired effect, thus leading to window frame leakage. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a compaction tool for window frame sealant.

[0005] The present invention provides a compaction tool for window frame sealant, which adopts the following technical solution: A compaction tool for window frame sealant includes an operating rod. One end of the operating rod is provided with a working head, and rubber protective plates are fixed to both sides of the working head. The other end of the operating rod is fixed with a connector one, and a connector two is provided to cooperate with connector one. An extension rod is fixed to connector two. Connectors one and connector two are the same shape and size and each is provided with a central hole and a peripheral hole. A fixing bolt can be detachably installed in the central hole, and a limit screw can be detachably installed in the peripheral hole.

[0006] By adopting the above technical solution, the working head is used to compress weather-resistant adhesive, and both sides are wrapped with rubber protective plates. The operating rod is connected to the reinforcing rod through joint one and joint two. At the same time, it is convenient to adjust the angle of the operating rod relative to the extension rod as needed. The initial connection of joint one and joint two is achieved by fixing bolts, and the relative rotation of joint one and joint two is restricted by limit screws. The use of the extension rod increases the overall length of this tool. The window frame sealant compaction tool of the present invention is easy to operate and has significant effects. It not only improves the sealing effect, but also effectively adapts to tall or irregular window frames.

[0007] Preferably, the working head is semi-circular, with both ends of the working head fixed to the side wall of the operating rod, and the rubber guard plate is adapted to the shape of the working head.

[0008] By adopting the above technical solution, the semi-circular working head effectively adapts to the working environment, is firmly connected to the operating lever, and is easy to operate.

[0009] Preferably, the operating rod head is provided with a receiving cavity that runs through its two opposite side walls, the working head is annular and is disposed in the receiving cavity, the working head is rotatably connected to the operating rod head through a connecting shaft that is limited and installed inside itself, and a positioning mechanism for limiting the rotation of the working head is installed on the operating rod.

[0010] By adopting the above technical solution, the operator can adjust the working range of the working head protruding from the operating lever according to actual usage needs. The working head is rotatably connected to the operating lever through a connecting shaft, and the working head is simultaneously positioned by a positioning mechanism to restrict the arbitrary rotation of the working head and keep it in working condition.

[0011] Preferably, an installation groove is provided on one side of the outer wall of the operating lever along the length direction. The connecting shaft includes a shaft rod passing through the working head. One end of the shaft rod is coaxially fixed to a gear plate, and the other end of the shaft rod is threaded with a nut. Both the gear plate and the nut are located in a countersunk groove on the surface of the operating lever. The positioning mechanism includes a push block that is slidably installed in the installation groove. One end of the push block near the connecting shaft is fixed to an insert rod that is slidably inserted into the inside of the operating lever. The head of the insert rod is movably inserted into the tooth groove of the gear plate.

[0012] By adopting the above technical solution, after the working head rotates, it pushes the push block towards the connecting shaft. The push block drives the insertion rod to move, and the head of the insertion rod is inserted into the tooth groove of the gear plate, thereby restricting the rotation of the gear plate and thus restricting the rotation of the working head. The push block can be fixed by friction.

[0013] Preferably, the push block has a hook groove on the side away from the connecting shaft, and a hook is rotatably connected to the head surface of the operating rod. The connecting shaft is located between the hook and the push block, and the hook is detachably hung on the push block through the hook groove.

[0014] By adopting the above technical solution, when the tool is not in use, it can be hung on the wall by a hook. When the tool is in use, after the push block is pushed, the hook is flipped towards the push block so that the hook is hooked on the push block through the hook groove, thereby restricting the directional movement of the push block and improving the positioning effect of the push block. The hook has a dual function.

[0015] Preferably, a limiting groove is provided along the length direction on the inner wall of the receiving cavity, and a pressure plate is movably installed in the limiting groove. A second inclined block is provided on the side of the pressure plate near the push block, and a first inclined block is provided on the side of the push block near the pressure plate. The inclined surface of the first inclined block fits with the inclined surface of the second inclined block. A rubber pad is provided on the side of the pressure plate near the working head. Overlapping edges are provided at the left and right ends of the pressure plate, and a disc spring is installed between the overlapping edge and the inner wall of the limiting groove. The disc spring has an elastic tendency to drive the pressure plate to move away from the working head.

[0016] By adopting the above technical solution, when the push block moves, it not only drives the insertion rod to move, but also drives the pressure plate to move through ramp block one, ramp block two and disc spring, so that the pressure plate and rubber pad apply pressure to the working head, so that both positions on the working head are fixed, further improving the positioning effect of the working head. The push block has a dual effect.

[0017] Preferably, a limiting groove is also provided on the inner wall of the other side of the receiving cavity along the length direction. The limiting groove is also provided with a pressure plate, a second inclined block, a rubber pad and a disc spring. A third inclined block is also slidably installed in the limiting groove. The inclined surface of the third inclined block fits with the inclined surface of the second inclined block. Pull wires are respectively connected between the front and rear sides of the push block and the front and rear sides of the third inclined block.

[0018] By adopting the above technical solution, when the pusher moves, the pressure plates on both sides of the working head apply pressure simultaneously. On the basis of the additional pressure plate, the positioning effect of the working head is further improved, resulting in a better positioning effect.

[0019] Preferably, the four corners of the operating lever are fixed with retaining edges along the length direction, the retaining edges having a quarter-circle cross section and the arc surface being close to the working head.

[0020] By adopting the above technical solution, the setting of the retaining edge avoids excess sealant from contaminating the surface of the operating rod with the push block and the opposite surface.

[0021] Preferably, a key is fixed to the surface of the shaft along the axial direction, and the shaft is detachably connected to the working head via the key.

[0022] By adopting the above technical solution and setting the key, it is easy to connect the shaft and the working head, so that the two can rotate synchronously.

[0023] Preferably, the distance between the overlap and the working head is greater than the distance between the pressure plate and the working head.

[0024] By adopting the above technical solution, a space to accommodate the disc spring is effectively formed, making the spatial distribution of the tool's components more reasonable. Attached Figure Description

[0033] The following combination Figures 1-7 The present invention will be described in further detail below.

[0034] This invention discloses a compaction tool for window frame sealant. Example

[0035] Reference Figures 1-2 A compaction tool for window frame sealant includes an operating rod 1. A semi-circular working head 2 is provided on the side of the head of the operating rod 1. Both ends of the working head 2 are fixedly connected to the operating rod 1. Rubber protective plates 3 are glued and fixed to both sides of the working head 2. The shape and length of the rubber protective plates 3 are adapted to the working head 2. A circular plate-shaped connector 4 is fixedly connected to the tail end of the working head 2. A central hole 41 is opened in the center of the connector 4, and a plurality of peripheral holes 42 are evenly opened around the central hole 41. The peripheral holes 42 are provided with internal threads.

[0036] Connector 2 5 is provided to match connector 4. Connector 2 5 has the same shape and size as connector 4, and an extension rod 6 is fixed to connector 2 5. Connector 2 5 has a center hole 41 and a peripheral hole 42 at the same position as connector 4. After the center hole 41 of connector 4 and the center hole 41 of connector 2 5 are aligned, connector 4 and connector 2 5 can be connected by passing through the mounting bolt 7. When connector 4 rotates relative to connector 2 5 to the required angle, the limiting screw 8 is screwed into the two aligned peripheral holes 42 to effectively limit the relative rotation of connector 4 and connector 2 5.

[0037] The implementation principle of Example 1 is as follows: The working head 2 is 8mm wide and 50mm long, with a semi-circular outer contour to accommodate extrusion work at various angles. Rubber protective plates 3 cover both sides, and the working head 2 in the middle is made of aluminum alloy to prevent damage to the window frame during the pressing process. The operating rod 1 has a cross-section of 12mm*25mm, is made of aluminum alloy, and is 20-30cm long. A 35mm diameter connector 4 is provided at the tail end for pressing the weather-resistant sealant onto high or irregularly shaped window frames.

[0038] The center of connector 4 has a 10mm center hole 41. The operating rod 1 and the extension rod 6 are initially connected using fixing bolts 7. At this point, the operating rod 1 and the extension rod 6 can still rotate relative to each other. After adjusting the angle of the operating rod 1, it is then fixed using the peripheral holes 42 and limiting screws 8. This allows for the application of weather-resistant sealant to the window frame. The extension rod 6 is connected to the operating rod 1 via connector 5 and connector 4, increasing the overall structural length to accommodate complex locations such as high places and irregularly shaped window frames. This window frame sealant compaction tool is easy to operate and has significant effects, not only improving the sealing effect but also effectively adapting to higher or irregularly shaped window frames. Example

[0039] Reference Figures 3-7 The difference between this embodiment and Embodiment 1 is that the working head 2 in this embodiment is annular, which is not only replaceable, but also allows for adjustment of the length and working range of the working surface protruding from the operating rod 1 according to usage needs. Both the left and right sides of the working head 2 protruding from the operating rod 1 can be used. The operating rod 1 is provided with a receiving cavity 11 that runs through its two opposite sides. The receiving cavity 11 is used to place the working head 2. A connecting shaft 21 that passes through the working head 2 is detachably installed on the head of the operating rod 1, so that the working head 2 can rotate within the receiving cavity 11 with the connecting shaft 21 as the center, thereby adjusting the working range of the working head 2.

[0040] The connecting shaft 21 includes a shaft 211 located in the middle. One end of the shaft 211 is coaxially fixed to a gear 212, and the other end of the shaft 211 is provided with an external thread and a nut 213 is threaded on it. The gear 212 and the nut 213 are both located in the countersunk grooves on both sides of the operating lever 1. A key 214 is fixed to the side wall of the shaft 211 along the axial direction, and the shaft 211 is connected to the working head 2 through the key 214.

[0041] The operating lever 1 is equipped with a positioning mechanism 9 for limiting the rotation of the connecting shaft 21, thereby limiting the rotation of the working head 2. A mounting groove 12 is provided along the length direction on one side of the outer wall of the operating lever 1. A push block 91 is slidably installed in the mounting groove 12. The surface of the push block 91 is provided with anti-slip texture. A hook groove 911 is provided on the side of the push block 91 away from the connecting shaft 21. An insert rod 92 is vertically fixed to the side of the push block 91 near the connecting shaft 21. The insert rod 92 slides through the operating lever 1 and is movably inserted into the tooth groove of the gear disk 212. That is, the rotation of the gear disk 212 is limited by inserting the insert rod 92 into the tooth groove.

[0042] Limiting grooves 13 are respectively provided on the two opposing inner walls of the receiving cavity 11. A pressure plate 93 is installed in the limiting groove 13. A rubber pad 931 for pressing contact with the working head 2 is bonded to the surface of the pressure plate 93. An overlap 932 is fixed to both ends of the pressure plate 93. The distance between the overlap 932 and the working head 2 is greater than the distance between the pressure plate 93 and the working head 2. A ramp block 94 is provided on the bottom surface of the push block 91. A disc spring 95 is installed between the overlap 932 and the inner wall of the limiting groove 13. The disc spring 95 has an elastic tendency to drive the pressure plate 93 to move away from the working head 2.

[0043] A second ramp block 96 is provided on the side of the pressure plate 93 near the push block 91, which cooperates with the first ramp block 94. The inclined surface of the second ramp block 96 is in contact with the inclined surface of the first ramp block 94. A third ramp block 97 is slidably installed on the side of the operating lever 1 away from the push block 91 along the length direction. The inclined surface of the third ramp block 97 is in contact with the inclined surface of the corresponding second ramp block 96. Two pull wires 98 are connected to the front and rear sides of the push block 91, respectively. The two pull wires 98 located on the front side of the push block 91 pass forward through the operating lever 1 and are connected to the third ramp block 97 by turning the head of the operating lever 1 to the rear. The connecting shaft 21 is located in the area between the two pull wires 98.

[0044] Two pull wires 98 located behind the push block 91 extend outwards into the operating lever 1 and, after turning inside the operating lever 1, connect to the ramp block 97. A hook 99 is hinged to the side of the operating lever 1 corresponding to the push block 91. The hook 99 is detachably hooked onto the push block 91 through the hook groove 911, thereby restricting the push block 91 from moving in the opposite direction. At the four corners of the operating lever 1, a retaining edge 14 is fixed along the length direction. The retaining edge 14 has a quarter-circle cross section, and the arc surface is close to the working head 2 to provide a guiding effect and prevent excess sealant from contaminating the surface of the operating lever 1 where the push block 91 is located and the opposite surface.

[0045] The implementation principle of Example 2 is as follows: The operator first pushes the working head 2 to one side to adjust the working surface range. At this time, the connecting shaft 21 rotates with the working head 2. Then, the push block 91 is pushed towards the head of the operating rod 1. When the push block 91 moves, it drives the insertion rod 92 to move, so that the insertion rod 92 is inserted into the tooth groove of the toothed disc 212. The insertion rod 92 restricts the rotation of the toothed disc 212, that is, restricts the rotation of the working head 2.

[0046] At the same time, push block 91 drives ramp block 1 94 to move, ramp block 1 94 pushes ramp block 2 96, push block 91 moves and pulls pull line 98, pull line 98 pulls ramp block 3 97, ramp block 1 94 and ramp block 3 97 respectively push the two pressure plates 93 closer to each other, disc spring 95 is elastically compressed, rubber pad 931 squeezes working head 2, restricting the rotation of working head 2 again. That is, only push block 91 is needed to restrict the movement of two positions of working head 2 through insert rod 92 and pressure plate 93 respectively, achieving a double positioning effect and better positioning effect.

[0047] Subsequently, the hook 99 is flipped towards the push block 91 and hooked into the hook groove 911, thereby restricting the reverse movement of the push block 91 and maintaining the positioning effect of the positioning mechanism 9 on the working head 2. After the tool is used, it can also be hung on the wall via the hook 99 for easy storage and future use. In this embodiment, the push block 91 has the dual function of simultaneously driving the insertion rod 92 and the pressure plate 93, and the hook 99 has the dual function of fixing the push block 91 and facilitating the hanging of the tool. The tool is very easy to operate, the working surface range can be adjusted according to the needs of use, and the working head 2 can be easily replaced, effectively adapting to more application scenarios.

[0048] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
