Description

Technical Field

[0001] This utility model relates to the field of door and window construction technology, specifically a door and window construction tightening device. Background Technology

[0002] In door and window construction, tightening is the core process to ensure accurate positioning, structural stability, and sealing performance of door and window frames. It mainly involves applying controllable pressure to the door and window frames using special tools or components to reduce the offset error between them and the wall opening, matching hardware, or sealing surface.

[0003] Chinese Patent Publication No. CN220929105U discloses a door and window construction tightening device, including a base plate. A through groove is formed on the side of the base plate. Clamping plates are slidably connected to the inner walls of both ends of the through groove via sliding grooves and sliders. A fixing frame is fixedly connected to the top surface of the base plate. Clamping components are arranged inside the through groove, and a support plate is positioned directly above the fixing frame. The two clamping plates in the through groove of this application allow the base plate to be fixed to the window opening, ensuring greater stability during support. It also facilitates convenient installation of the base plate, increasing the stability of the tightening device. The height of the support plate can be quickly adjusted by rotating a knob, and the screw adjustment ensures more precise height adjustment, facilitating quick leveling of the window frame and increasing the practicality of the device.

[0004] In the aforementioned prior art, the device can be clamped at the window opening by clamping plates on both sides. The window frame can be supported by adjusting the height of the support plate. However, the fixing measures of this device mainly rely on the elastic force of the torsion spring and the clamping force of the clamping plate. Since the window frame has a certain weight, the clamping plate is prone to affecting the stability of the support due to insufficient clamping force during the support process. Moreover, the support plate lacks protective measures, and the supported window frame may tilt outward. Therefore, a door and window construction clamping device is needed to meet people's needs. Utility Model Content

[0005] The purpose of this utility model is to provide a door and window construction clamping device to solve the problem that the door and window clamping device mentioned in the background art mainly relies on the elastic force of the torsion spring and the clamping force of the clamping plate. During the support process, the clamping plate is prone to affecting the support stability due to insufficient clamping force, and there is a lack of protective measures, which may cause the supported window frame to tilt outward.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a door and window construction tightening device, comprising several U-shaped seats, a guide rod installed on the inner wall of the U-shaped seat, a positioning structure connected to the guide rod, an installation plate detachably installed on the U-shaped seat, a support structure connected to the installation plate, a second lead screw rotatably installed on the installation plate, and an adjustment structure connected to the second lead screw.

[0007] Furthermore, the positioning structure includes two positioning clamps, both of which are slidably mounted on a guide rod. Two springs are slidably sleeved on the guide rod. One end of each spring is mounted on one side of the two positioning clamps, and the other end of each spring is mounted on the inner walls of both sides of the U-shaped seat. Expansion bolts are inserted into the interior of each positioning clamp.

[0008] Furthermore, a gear is rotatably mounted inside the U-shaped seat, and racks are mounted on one side of each of the two positioning plates, with both racks meshing with the gears.

[0009] Furthermore, the support structure includes a support plate, which is slidably mounted on a mounting plate. A threaded slide plate is slidably mounted inside the support plate, and a lead screw is threadedly mounted inside the threaded slide plate. The lead screw is rotatably mounted inside the support plate. An L-shaped baffle is detachably mounted on one side of the threaded slide plate. Several mounting screws are inserted inside the mounting plate, and one end of each mounting screw is threadedly mounted inside a U-shaped seat.

[0010] Furthermore, a fixing screw is inserted inside the L-shaped baffle, and one end of the fixing screw passes through the L-shaped baffle and is threaded into the inside of the threaded slide plate.

[0011] Furthermore, the support plate has a guide groove inside, and the threaded slide plate is slidably installed in the guide groove.

[0012] Furthermore, the adjustment structure includes two threaded slides, both of which are slidably mounted on one side of the mounting plate and threaded onto the lead screw. One end of each of the two threaded slides is rotatably mounted on one end of a connecting rod, and the other end of each connecting rod is rotatably mounted below the support plate.

[0013] Furthermore, a limiting guide rod is installed below the support plate, and the limiting guide rod is slidably installed inside the mounting plate.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] (1) When using this utility model, the U-shaped seat can be clamped on the walls on both sides of the window opening using the positioning clamp. After adjusting the level, it can be fixed with expansion bolts. Then, U-shaped seats are installed around the window opening, and the window frame can be supported on the support plate. At the same time, the L-shaped baffle can be used to protect the outside of the window frame to prevent it from tilting outwards, thus achieving a tight support effect on the window frame. Furthermore, the support position of the support plate can be adjusted by rotating the screw rod to make it closer to or further away from the window frame, thereby adjusting the tightness and making it convenient to adjust according to the size of the window frame.

[0016] (2) The position of the L-shaped baffle can be adjusted by rotating the screw, and the L-shaped baffle will push the window frame on the support plate to move horizontally, so as to fine adjust the installation position of the window frame. After removing the L-shaped baffle and moving the threaded slide to the other side of the window frame, the L-shaped baffle is reinstalled to fit the other side of the window frame. Then, the screw is rotated again to adjust the position of the L-shaped baffle, and the L-shaped baffle can push the window frame to move in the opposite direction, so as to flexibly adjust according to the installation requirements.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a door and window construction tightening device, including several U-shaped seats 100, a guide rod 200 installed on the inner wall of the U-shaped seat 100, a positioning structure connected to the guide rod 200, the positioning structure being used for fixing at the window opening, an installation plate 300 detachably installed on the U-shaped seat 100, a support structure connected to the installation plate 300, the support structure being used for supporting the window frame and being able to adjust the support position according to the window frame size, a second lead screw 400 rotatably installed on the installation plate 300, an adjustment structure connected to the second lead screw 400, the adjustment structure being used for fine-tuning the horizontal position of the window frame.

[0025] Furthermore, the positioning structure includes two positioning clamps 201, both of which are slidably mounted on the guide rod 200. Two springs 202 are slidably sleeved on the guide rod 200. One end of each spring 202 is mounted on one side of the two positioning clamps 201, and the other end is mounted on the inner walls of both sides of the U-shaped seat 100. Expansion bolts 203 are inserted inside each of the two positioning clamps 201. Pulling the positioning clamps 201 on both sides causes them to slide and unfold on the guide rod 200. During the movement of the positioning clamps 201, the springs 202 are compressed. Then, the positioning clamps 201 on both sides are placed on the walls on both sides of the window opening. When the positioning clamps 201 are released, the spring force of the springs 202 pushes the positioning clamps 201 to clamp onto the window opening for positioning.

[0026] Furthermore, a gear 204 is rotatably mounted inside the U-shaped base 100, and a rack 205 is mounted on one side of each of the two positioning clamps 201. Both racks 205 mesh with the gear 204. During the movement of the positioning clamps 201, the corresponding racks 205 will move. When the racks 205 move, they will drive the gears 204 to rotate through meshing with the gears 204, thereby enabling the other rack 205 to move in the opposite direction. By utilizing the meshing of the gears 204 and the two racks 205, the moving distance of the positioning clamps 201 on both sides can be made the same.

[0027] Furthermore, the support structure includes a support plate 301, which is slidably mounted on a mounting plate 300. A threaded slide plate 302 is slidably mounted inside the support plate 301, and a lead screw 303 is threadedly mounted inside the threaded slide plate 302. The lead screw 303 is rotatably mounted inside the support plate 301. An L-shaped baffle 304 is detachably mounted on one side of the threaded slide plate 302. Several mounting screws 307 are inserted inside the mounting plate 300, and one end of each mounting screw 307 is threaded into the U-shaped seat 100. The window frame rests on the support plate 301 around the perimeter. 1. The L-shaped baffle 304 can provide protection for the outside of the window frame. Rotating the screw 303 can drive the threaded slide plate 302 to move. The threaded slide plate 302 will drive the L-shaped baffle 304 to move. The L-shaped baffle 304 will push the window frame to move. When it is necessary to move the window frame in the opposite direction, the L-shaped baffle 304 can be removed. Then, the position of the threaded slide plate 302 can be adjusted so that it passes from the bottom of the window frame to the other side. Then, the L-shaped baffle 304 can be reinstalled so that it fits against the other side of the window frame. At this time, controlling the movement of the fixing screw 305 can push the window frame to move in the opposite direction.

[0028] Furthermore, a fixing screw 305 is inserted inside the L-shaped baffle 304. One end of the fixing screw 305 passes through the L-shaped baffle 304 and is threaded into the threaded slide plate 302. The fixing screw 305 can pass through the L-shaped baffle 304 and be screwed into the threaded slide plate 302 to fix the position of the L-shaped baffle 304. Conversely, the L-shaped baffle 304 can be removed by rotating and unscrewing the fixing screw 305.

[0029] Furthermore, the support plate 301 has a guide groove 306 inside, and the threaded slide plate 302 is slidably installed in the guide groove 306. When the threaded slide plate 302 moves, it will slide in the guide groove 306. The guide groove 306 can restrict the movement direction of the threaded slide plate 302.

[0030] Example 2: As Figure 2-3 To facilitate fine-tuning of the window frame's installation position, an adjustment structure is provided. This structure includes two threaded slide blocks 401, each slidably mounted on one side of the mounting plate 300 and threaded onto a lead screw 400. Two connecting rods 402 are rotatably mounted on one end of each of the two slide blocks 401. The other ends of the connecting rods 402 are rotatably mounted below the support plate 301. A limiting guide rod 403 is installed below the support plate 301 and slidably mounted inside the mounting plate 300. Rotating the lead screw 400 simultaneously controls the two threaded slide blocks 401 to move closer or further apart. When the two threaded slide blocks 401 move, they pull one end of the connecting rods 402 on both sides to move accordingly, thereby causing the support plate 301 to move closer or further away from the window frame for support. This allows for adjustment of the position of the surrounding support plates 301 according to the window frame size. The remaining features are the same as in Embodiment 1.

[0031] The working principle is as follows: First, pull the positioning clamps 201 on both sides to slide them on the guide rod 200, causing the positioning clamps 201 to unfold. During the movement of the positioning clamps 201, the spring 202 will be compressed. Then, place the positioning clamps 201 on the walls on both sides of the window opening. Release the positioning clamps 201; at this point, the spring force of the spring 202 will clamp the positioning clamps 201 onto the window opening for positioning. After adjusting the U-shaped seat 100 and the support plate 301 to ensure they are level, drill holes in the wall and screw the expansion bolts 203 into the positioning clamps 201. Screwing the expansion bolts 203 into the drilled holes will reinforce the connection of the U-shaped seat 100. Installing the U-shaped seats 100 around the window opening allows the window frame to rest on the surrounding support plates 301. The L-shaped baffle 304 provides protection to the outside of the window frame, preventing it from tilting outwards. Figure 1 During window frame installation, the support distance of the support plate 301 can be adjusted according to the window frame size. Adjustment is achieved by rotating the second lead screw 400. The two ends of the second lead screw 400 have oppositely oriented threads, each threaded to one of two threaded slide blocks 401. Rotation of the second lead screw 400 simultaneously controls the two threaded slide blocks 401 to move closer or further apart. When the two threaded slide blocks 401 move closer, they pull one end of the connecting rods 402 on both sides to rotate closer, thus moving the support plate 301 towards the mounting plate 300. This movement of the support plate 301 causes the limiting guide rod 403 to slide inside the mounting plate 300, thus restricting the direction of movement of the support plate 301 and preventing it from shifting. Conversely, when the two threaded slide blocks 401 move further apart, they push the two connecting rods 402 to move accordingly. One end of each connecting rod pushes the support plate 301 to move further apart. The support plate 301 moves away from the mounting plate 300 to adjust the position of the surrounding support plates 301 according to the window frame size. By rotating the lead screw 303, it can drive the threaded slide plate 302 to move through the threaded engagement with the threaded slide plate 302. The threaded slide plate 302 will slide in the guide groove 306 and drive the L-shaped baffle 304 to move. The L-shaped baffle 304 will push the window frame on the support plate 301 to move inward toward the room. When it is necessary to move the window frame in the opposite direction, the fixing screw 305 can be unscrewed first to remove the L-shaped baffle 304. Then, the position of the threaded slide plate 302 can be adjusted so that it passes from the bottom of the window frame to the other side. Then, the L-shaped baffle 304 can be reinstalled so that the L-shaped baffle 304 fits against the other side of the window frame. At this time, controlling the movement of the L-shaped baffle 304 can push the window frame to move in the opposite direction to fine-tune the installation position of the window frame in the window opening.

[0032] After the support is completed, foam or concrete can be poured between the window opening and the window frame for fixation. When filling, avoid the U-shaped seat 100 and its components. After the window frame is completely fixed in the window opening, the screw rod 400 can be rotated to move the support plate 301 toward the mounting plate 300 and away from the support of the window frame. Then, the fixing screw 305 can be rotated out to remove the L-shaped baffle 304 to avoid the L-shaped baffle 304 from obstructing the window frame. Then, the mounting screw 307 can be rotated out to separate the mounting plate 300 from the U-shaped seat 100, making it easy to pull the mounting plate 300 out of the window opening. At the same time, it allows room for movement above the U-shaped seat 100. After exceeding the expansion bolt 203, pull the positioning clamps 201 on both sides to release them from the clamp on the window opening wall, so that the U-shaped seat 100 and its components can be removed, making it easier to fix the window frame later.
