Description

Technical Field

[0001] This invention relates to the technical field of furniture installation equipment, and more specifically to a wooden door installation device. Background Technology

[0002] Currently, wooden door installation is a technical job. Installers need specialized training before entering the industry, and experienced installers guide them for a period before actual installation, resulting in high initial training costs. Furthermore, the number of installers is relatively small. When someone needs a door installed, the installer needs to bring all necessary tools to the installation location. Additionally, installing wooden doors requires multiple workers to cooperate. For example, door alignment is crucial, but a gap must be left at the bottom. Hinges require pre-fixing a screw to each hinge before final adjustment, causing instability and easy swaying or shifting. This necessitates additional support and stabilization to keep the door upright. Moreover, leaving a gap at the bottom makes it easy for the door to wobble when lifted, leading to significant installation errors and wasting time and effort. Therefore, the existing wooden door installation methods require multiple installers to work together, resulting in high costs in terms of manpower, transportation, and training, which in turn leads to excessively high installation costs for wooden doors. Summary of the Invention

[0003] The present invention aims to provide a wooden door installation device to solve the technical problem of high installation cost of wooden doors in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wooden door installation device, including a bracket and a limiting mechanism, the bracket including a support plate and a lifting mechanism, the lifting mechanism being a telescopic rod with telescopic function, the telescopic rod being rotatably mounted on the support plate; the limiting mechanism including a limiting block, the limiting block having a groove for accommodating a wooden door, the limiting block and the support plate being rotatably connected.

[0005] The principle and advantages of this solution are as follows: The support plate provides support for the limiting block and the lifting mechanism, forming a device for installing wooden doors. During use, one end of the wooden door is inserted into the groove on the limiting block, and then the door is placed on the support plate. The support plate provides support for the door, and the extension rod pushes the door upwards, causing it to flip upwards until it stands upright. The limiting block provides a limiting function for the door, preventing instability and thus achieving the goal of automatically lifting and stably maintaining the door in an upright position. Therefore, using this solution requires only one installer, saving labor costs. Furthermore, the solution has a simple structure, is easy to use, and saves on training costs for door installers.

[0006] Preferably, as an improvement, a second rotating shaft is fixedly connected to the limiting block, and sliders are respectively rotatably provided at both ends of the second rotating shaft, with the sliders and the support plate being slidably connected.

[0007] This solution connects the limiting block and the support plate via a slider, allowing the limiting block to not only rotate the wooden door to an upright position but also slide relative to the support plate. This adjusts the height of the limiting block, thereby achieving the goal of adjusting the height of the wooden door, resulting in more precise alignment and accurate installation.

[0008] Preferably, as an improvement, the pallet is also provided with an adjustment mechanism for adjusting the height of the limit block. The adjustment mechanism includes a drive gear and a power source for driving the drive gear to rotate. The slider is provided with a rack, and the drive gear and the rack mesh with each other.

[0009] This solution automatically adjusts the height of the slider through an adjustment mechanism, further reducing the labor intensity of installers. Moreover, this solution directly drives the drive gear to rotate via a power source, which in turn drives the slider to slide, achieving the purpose of adjusting the height of the slider. The structure is simple and easy to operate.

[0010] Preferably, as an improvement, the pallet is provided with a receiving cavity for accommodating the lifting mechanism, and a third rotating shaft is rotatably provided inside the receiving cavity, with the telescopic rod and the third rotating shaft fixed.

[0011] The telescopic rod of this design can rotate around the third rotation axis. Normally, the telescopic rod is rotated into the receiving cavity, which can accommodate the lifting mechanism, reducing the overall volume of the invention and facilitating storage and transfer. During use, the telescopic rod is rotated out, and it can be extended or retracted towards the wooden door to lift the door.

[0012] Preferably, as an improvement, the cavity is further provided with a drive component for driving the third rotating shaft to rotate.

[0013] The drive unit of this solution can automatically drive the third rotating shaft to rotate, thereby automatically rotating the telescopic rod into or out of the receiving cavity, further reducing the labor intensity of installers.

[0014] Preferably, as an improvement, the pallet includes a first pallet and a second pallet, with the telescopic rod rotatably mounted on the first pallet; at least two square rods are fixedly mounted on the second pallet; the first pallet has a groove for accommodating the square rods, with the square rods slidingly engaging with the groove; a transmission gear is coaxially fixed on a third rotating shaft, and a transmission rack is mounted on the square rod near the transmission gear, with the transmission gear and the transmission rack meshing with each other.

[0015] This design divides the tray into two parts and connects them via a square rod, allowing users to adjust the overall length of the tray. During normal storage, the first and second trays can be folded together, shortening the overall length of the bracket and saving storage space. Simultaneously, when the square rod slides out, it drives the transmission gear to rotate, which in turn drives the third rotating shaft. The third rotating shaft then drives the telescopic rod, automatically rotating the telescopic rod out of the receiving cavity during the bracket opening process. This eliminates the need for installers to manually rotate the telescopic rod, further reducing operation steps and saving installers' time.

[0016] Preferably, as an improvement, the limiting mechanism further includes a horizontal limiting component, which includes two limiting blocks arranged opposite to each other. The two limiting blocks are slidably disposed on both sides of the support plate, and the limiting block and the two limiting blocks form a three-sided enclosure structure for the wooden door.

[0017] This solution uses a horizontal limiting component to restrict and adjust the horizontal position of the wooden door. Combined with the limiting and supporting function of the limiting block, it can uniquely fix the position of the wooden door.

[0018] Preferably, as an improvement, the pallet is also provided with a drive component for moving the limit block.

[0019] This solution utilizes a driving component to slide two limiting blocks, allowing for adjustment of their positions. This makes the solution suitable for wooden doors of different widths and also facilitates door alignment.

[0020] Preferably, as an improvement, several balls are movably installed in the groove.

[0021] The ball bearings in this design reduce frictional damping between the wooden door and the inner wall of the groove, making it easier to adjust the horizontal position of the wooden door.

[0022] Preferably, as an improvement, the pallet is provided with a telescopic mechanism for adjusting the length of the pallet.

[0023] The retraction mechanism of this solution can adjust the length of the tray. During use, the retraction mechanism is in an extended state, allowing the tray to meet the length requirements of the wooden door. After installation, the retraction mechanism can be shortened, thereby shortening the length of the entire bracket, making the bracket of this solution easier to move and carry.

[0036] Example 1

[0037] As attached Figure 1 The image shows a wooden door installation device, including a bracket and a limiting mechanism. The bracket includes a support plate 1, a lifting mechanism, and a limiting mechanism. Rollers 2 are rotatably mounted on the support plate 1, located at its left and right ends. Taking the right-end roller 2 as an example, its specific arrangement is explained as follows: A bracket 15 is bolted to the right end of the support plate 1; two brackets 15 are arranged side-by-side as an example. The bracket 15 has a through hole, through which a first rotating shaft 14 is rotatably connected via bearings. Each end of the first rotating shaft 14 is rotatably connected to a roller 2 via bearings. A baffle 16 for blocking the rollers 2 is also bolted to the support plate 1. In actual production, a caster wheel can be installed at each of the four corners of the support plate 1 instead of the rollers 2. Casters are common existing technology and will not be elaborated upon here.

[0038] like Figure 1 , Figure 2 As shown, the lifting mechanism is a telescopic rod with telescopic function. Here, we take the first electric telescopic rod 13 as an example. The first electric telescopic rod 13 is rotatably mounted on the support plate 1, and the specific arrangement is as follows: The support plate 1 has a receiving cavity 9 for accommodating the lifting mechanism. A third rotating shaft 10 is rotatably connected to the side wall of the receiving cavity 9 through a shaft hole. The receiving cavity 9 also has a driving component for driving the third rotating shaft 10 to rotate. Here, we take a motor as an example (the motor is not shown in the figure). The motor is located on the side wall of the receiving cavity 9 and is fixed to the support plate 1 by bolts. The output shaft of the motor is coaxially engaged and fixed to the third rotating shaft 10. Two sleeves 11 are engaged and fixed in the middle of the third rotating shaft 10. Mounting blocks 12 are welded and fixed to the sleeves 11. The lower end of the first electric telescopic rod 13 is fixed to the mounting blocks 12 by bolts.

[0039] like Figure 1 As shown, the limiting mechanism includes a limiting block 3 and a second rotating shaft 8 for mounting the limiting block 3. The limiting block 3 has a groove 4 for accommodating the wooden door. The shape of the limiting block 3 is as follows: Figure 3 and Figure 4As shown. This example uses two limiting blocks 3. The two limiting blocks 3 are fixed side-by-side on the second rotating shaft 8, with a certain space between them. Each end of the second rotating shaft 8 is rotatably connected to a slider 5 via bearings. The left end of the slider 5 is vertically slidably connected to the support plate 1 via a guide rail, and the right end face of the slider 5 has an integrally formed rack. The support plate 1 also has an adjustment mechanism for adjusting the height of the limiting blocks 3. The adjustment mechanism includes a drive gear 7 and a power source that drives the drive gear 7. The power source is a drive motor 6, here taking a stepper motor as an example. The drive motor 6 is fixed to the support plate 1 with bolts, and the output shaft of the drive motor 6 is coaxially fixed to the drive gear 7. The drive gear 7 and the rack mesh with each other. Two adjustment mechanisms are provided here, located at both ends of the second rotating shaft 8, and are mirror-symmetrically arranged about the perpendicular bisector of the second rotating shaft 8. They are used to synchronously provide driving force to the sliders 5 on both sides of the second rotating shaft 8, so that the forces on both ends of the second rotating shaft 8 are balanced.

[0040] like Figure 5 As shown, the end of the second rotating shaft 8 is also integrally formed with a boss 17 for limiting the rotation amplitude of the second rotating shaft 8, and the slider 5 is provided with a receiving groove for the boss 17 to slide.

[0041] The specific implementation process is as follows: Place the wooden door on the support plate 1 and insert the right end of the wooden door into the groove 4 on the limiting block 3. Then start the motor, which drives the third rotating shaft 10 to rotate clockwise. The third rotating shaft 10 drives the sleeve 11 and the mounting block 12 to rotate clockwise together. The mounting block 12 drives the first electric telescopic rod 13 to rotate clockwise, thereby lifting the left end of the wooden door upward. Then, start the first electric telescopic rod 13 to extend it. The first electric telescopic rod 13 continues to lift the left end of the wooden door upward, causing the wooden door to rotate clockwise around the second rotating shaft 8 until the wooden door is rotated to an upright position, thereby achieving the purpose of keeping the wooden door stably upright and facilitating the installation by workers.

[0042] The boss 17 of this solution can limit the rotation range of the second rotating shaft 8, and thus limit the rotation range of the limiting block 3, so that the limiting block 3 can only rotate to the vertical position and cannot continue to rotate clockwise. This avoids the situation where the wooden door is tilted due to uneven force on both sides after the wooden door is rotated to the vertical position, and further ensures that the wooden door can stably maintain the vertical position.

[0043] When the height of the wooden door is not aligned, the drive motor 6 can be activated to rotate the drive gear 7, which in turn causes the slider 5 to slide up and down. Figure 5(From a certain perspective), the slider 5 drives the second rotating shaft 8 to slide up and down, the second rotating shaft 8 drives the limit block 3 to slide up and down, and the limit block 3 drives the wooden door to slide up and down, thereby achieving the purpose of adjusting the height of the wooden door.

[0044] The rollers 2 in this design allow workers to easily adjust the position of the support plate 1, thereby achieving the purpose of adjusting the position of the wooden door. During use, the bracket can be pushed to the door frame, causing the wooden door to be pushed upwards into an upright position, perfectly matching the door frame. Workers can then directly connect the wooden door to the door frame using screws and hinges.

[0045] The baffle 16 in this solution can shield the roller 2, preventing sawdust and other impurities from falling into the installation position of the roller 2 and causing the roller 2 to get stuck and unable to rotate normally; at the same time, it can also prevent the roller 2 from causing injury to nearby workers, thus playing a safety protection role.

[0046] Therefore, when using the brackets of this solution to install wooden doors, only one person is needed to install the doors, saving labor costs. At the same time, the structure of this solution is simple and easy to use, saving training costs for wooden door installers. Moreover, the wooden doors installed using this solution can be stably kept upright at the required height, improving the final installation quality of the wooden doors.

[0047] Example 2

[0048] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that the pallet 1 is provided with a telescopic mechanism for adjusting the length of the pallet 1. The retraction mechanism is a second electric telescopic rod 18. There are multiple second electric telescopic rods 18, and two are used as an example here. The two second electric telescopic rods 18 are arranged parallel to each other. The pallet 1 includes a first pallet 19 and a second pallet 20. Here, the one on the left end is named the first pallet 19, and the one on the right end is named the second pallet 20. Both the first pallet 19 and the second pallet 20 are provided with blind holes (not shown in the figure) for accommodating the second electric telescopic rod 18. Specifically, the first blind hole is provided at the right end of the first pallet 19, and the second blind hole is provided at the left end of the second pallet 20. The left end of the second electric telescopic rod 18 is snapped and fixed at the bottom of the first blind hole, and the right end of the second electric telescopic rod 18 is snapped and fixed at the bottom of the second blind hole.

[0049] During use, the shrinkage mechanism is in Figure 6The extended state shown allows the support plate 1 to meet the length requirements of the wooden door. After the wooden door is installed, the second electric telescopic rod 18 is activated to shorten it, thereby shortening the length of the entire bracket. In this solution, because the first and second blind holes can accommodate the length of the second electric telescopic rod 18, when it is retracted to its shortest state, the right end of the first support plate 19 and the left end of the second support plate 20 can be pressed together. Therefore, the retraction mechanism of this solution can significantly shorten the length of the bracket, making the bracket of this solution easier to transfer and carry.

[0050] Example 3

[0051] like Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the limiting mechanism also includes a horizontal limiting component. The horizontal limiting component includes two limiting blocks arranged opposite to each other. The two limiting blocks are slidably disposed on both sides of the support plate 1. For ease of explanation, the one located on the upper side is named the first limiting block 21, and the one located on the lower side is named the second limiting block 22. The first limiting block 21 and the second limiting block 22 are slidably disposed on both sides of the support plate 1. The first limiting block 21, the second limiting block 22 and the limiting block 3 respectively play a supporting and pressing role on the three sides of the wooden door. The pallet 1 is also equipped with a driving component for moving the first limiting block 21 and the second limiting block 22. Here, the setting of the driving component is described using the second limiting block 22 as an example. The driving component is a third electric telescopic rod 23. The upper end of the third electric telescopic rod 23 is fixed to the pallet 1 by bolts, and the lower end of the third electric telescopic rod 23 is fixed to the second limiting block 22 by bolts. The extension and retraction of the third electric telescopic rod 23 causes the second limiting block 22 to move away from or closer to the pallet 1, thereby achieving the purpose of the second limiting block 22 sliding relative to the pallet 1.

[0052] like Figure 8 As shown, a number of balls 24 are movably installed in the groove 4 on the limiting block 3. Specifically, the bottom of the groove 4 has a groove to accommodate the balls 24. There is a gap between the balls 24 and the inner circumferential wall of the groove. The upper end of the groove has an integrally formed flange to prevent the balls 24 from falling out, so that the balls 24 can rotate in the groove without falling out of the groove.

[0053] When using this solution, first activate the drive mechanism to move the first limiting block 21 and the second limiting block 22 away from each other, increasing the distance between them. Then, place the wooden door onto the tray 1. After the wooden door is placed on the tray 1, the drive mechanism can also be activated to slide the first limiting block 21 and the second limiting block 22, thereby adjusting the position of the wooden door. For example, when the wooden door needs to slide to the lower right, drive the first limiting block 21 and the second limiting block 22 to slide to the lower right. The first limiting block 21 will push the wooden door to the lower right, causing it to slide to the lower right, while the second limiting block 22 will limit the lower side of the wooden door, preventing it from tilting and being unable to slide to the lower right, and also preventing the wooden door from slipping off. The ball bearing 24 reduces the frictional damping between the wooden door and the inner wall of the groove 4, making it easier to adjust the horizontal position of the wooden door.

[0054] Example 4

[0055] like Figure 9 , Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that the pallet 1 includes a first pallet 19 and a second pallet 20. Here, the one on the left is named the first pallet 19 and the one on the right is named the second pallet 20. The first electric telescopic rod 13 is located on the first pallet 19. At least two square rods 25 are fixedly mounted on the second pallet 20 by bolts. Two square rods 25 are shown in the figure as an example. The first pallet 19 is provided with a groove 26 for accommodating the square rods 25. The square rods 25 can be inserted into the groove 26 and can slide relative to the groove 26, so that the square rods 25 can slide relative to the first pallet 19. A transmission gear 27 is coaxially engaged and fixed on the third rotating shaft 10. A transmission rack is integrally formed on the square rod 25 near the transmission gear 27, and the transmission gear 27 and the transmission rack mesh with each other. When the lifting mechanism is in a non-working state, the first electric telescopic rod 13 is located on the right side of the third rotating shaft 10.

[0056] When installing the wooden door, slide the second support plate 20 to the right, causing the square rod 25 to slide outwards, thereby increasing the overall length of the bracket and providing more stable support for the wooden door. When the square rod 25 slides out to the position where the transmission rack and transmission gear 27 mesh, the square rod 25, while sliding to the right, will drive the transmission gear 27 to rotate counterclockwise. The transmission gear 27 will drive the third rotating shaft 10 to rotate counterclockwise, and the third rotating shaft 10 will drive the first electric telescopic rod 13 to rotate counterclockwise, thereby causing the first electric telescopic rod 13 to rotate to... Figure 10 As shown in the tilted state, the installer can directly place the wooden door on the upper side of the first electric telescopic rod 13, and then start the first electric telescopic rod 13 to lift the wooden door upward, without having to rotate the first electric telescopic rod 13 to the tilted state separately.

[0057] After installation, as the square rod 25 is slid to the left and retracted into the first tray 19, it will simultaneously drive the transmission gear 27 and the third rotating shaft 10 to rotate in the opposite direction, thereby driving the first electric telescopic rod 13 to rotate in the opposite direction and return to the receiving cavity 9, thus achieving the purpose of reducing the volume of the entire installation equipment and making it easier to carry and transfer.

[0058] In actual operation, the length of the transmission rack required for the transmission gear 27 to rotate a certain angle can be calculated based on the transmission ratio of the transmission gear 27 and the transmission rack. For example, if the length of the transmission rack required for the transmission gear 27 to rotate 45° is L, then a transmission rack of length L is machined at the right end of the square rod 25, thereby achieving the purpose of accurately controlling the rotation amplitude of the first electric telescopic rod 13.

[0059] The above descriptions are merely embodiments of the present invention, and common knowledge such as specific technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
