Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a positioning device for installing door and window hardware. Background Technology

[0002] Patent application number CN202221669806.6 discloses a door and window hardware positioning device. This solution can solve the problem that in actual engineering construction, it is necessary to first assemble the frame and sash, then measure the position of the window sash locking point according to the drawing dimensions using measuring tools, mark the position, and then install the locking block. The construction efficiency is extremely low, and there are also large installation errors, making it unsuitable for mass production. However, this solution does not address the fact that existing positioning tools mostly use a single fixed structure, such as clamping with mechanical clamps or magnetic adsorption. This cannot adapt to different materials of doors, windows and door frames (such as wood, plastic, metal, etc.), is prone to slipping on smooth surfaces, and is difficult to fix on non-magnetic materials, causing the device to shift during the positioning process and affecting the installation stability.

[0003] The fixing and clamping operation of traditional positioning devices requires manual adjustment in steps, such as rotating bolts to fix the clamps and manually suction cups. The steps are complicated, difficult for a single person to operate, and have low installation efficiency, especially in batch installation scenarios, which is time-consuming and labor-intensive.

[0004] Traditional methods mainly rely on manual visual inspection combined with measuring tape to determine the hinge position. However, due to the operator's experience and visual errors, it is difficult to guarantee the levelness and dimensional accuracy, and problems such as hinge tilt and uneven spacing are prone to occur. This requires repeated adjustments and increases construction costs. Utility Model Content

[0012] Preferably, the bubble level is used to indicate the horizontal state of the device, and the scale is used for preliminary measurement and marking of the hinge installation position.

[0013] Preferably, the suction cup and the strong magnet are used to attach the device to the surface of a door, window, or door frame.

[0015] Preferably, a reinforcing rib is fixedly connected to the gripper support rod to enhance the structural strength of the gripper support rod.

[0016] Preferably, the micro vacuum pump creates a negative pressure inside the suction cup through the vacuum device to achieve adsorption; pressing the suction cup button controls adsorption and release.

[0017] Preferably, the micro motor drives the threaded rod to rotate, causing the slider to move linearly, which in turn drives the gripper to perform clamping or releasing actions through the gripper support rod; pressing the gripper button can control clamping or releasing.

[0018] Preferably, the limiting block is used to prevent the slider from moving excessively, which could damage the gripper support rod or related components.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) The positioning device installed on the door and window hardware has a buffer anti-slip pad on the claw that can not only avoid surface damage caused by hard contact between the claw and the door and window, but also prevent the door and window from sliding when clamped. The heat dissipation holes at the bottom of the box can dissipate the heat of the internal motor and vacuum pump in time, ensuring the continuous and stable operation of the equipment, and solving the problem that the existing device is prone to damage to the workpiece or failure due to overheating.

[0021] (2) The positioning device installed on the door and window hardware has a suction cup button and a gripper button in the middle of the two handles that can control the suction cup to adsorb / release and the gripper to clamp / release respectively. No complicated operation steps are required. The operator can complete the key control by holding the handle with one hand. Compared with the existing technology that requires manual adjustment of the fixed structure, the operation process is significantly simplified.

[0022] (3) The positioning device installed on the door and window hardware has suction cups and strong magnets arranged in a cross pattern on the side of the box. It can be adsorbed onto smooth surfaces by suction cups and onto iron-containing materials by strong magnets.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Please see Figure 1-4 This utility model provides a technical solution: a positioning device for installing door and window hardware, including a box body 1, with handles 2 fixedly connected to both ends of the outer side of the box body 1, a suction cup button 5 and a gripper button 6 fixedly connected between the two handles 2, a spirit level 4 fixedly connected to the middle part of the top of the box body 1, and a scale 3 fixedly connected to the upper edge of the box body 1. When the operator holds the handles 2 at both ends of the outer side of the box body 1, he can judge whether the device is in a horizontal state by checking the spirit level 4 in the middle part of the top of the box body 1. The scale 3 at the upper edge of the box body 1 is used to perform preliminary size measurement and marking of the hinge installation position, providing basic data for hinge positioning.

[0034] The sides of the box 1 are respectively fixedly connected with suction cups 14 and strong magnets 15 in a cross manner to fix the device to the surface of doors, windows or door frames.

[0035] The box 1 has a heat dissipation hole 11 at the bottom. The heat dissipation hole 11 can dissipate the heat generated by the miniature vacuum pump 12 and miniature motor 16 inside the box 1 in time, ensuring that the two operate continuously and stably, and ensuring the normal operation of the device.

[0036] A miniature vacuum pump 12 is fixedly connected inside the box 1. A vacuum device 13 is fixedly connected to the miniature vacuum pump 12. The vacuum device 13 is fixedly connected to the suction cup 14 outside the box 1. When the suction cup 14 is used for fixation, the suction cup button 5 is pressed to control the suction and release of the suction cup 14. The miniature vacuum pump 12 fixedly connected inside the box 1 is started, and the vacuum device 13 connected to it works accordingly, so that a negative pressure is formed inside the suction cup 14, thereby firmly adhering to the smooth surface of the door, window or door frame.

[0037] A micro motor 16 is fixedly connected inside the box body 1. A threaded rod 17 is fixedly connected to the output end of the micro motor 16. A slider 18 is fixedly connected to the threaded rod 17. A gripper support rod 7 is fixedly connected around the slider 18. A reinforcing rib 8 is fixedly connected to the gripper support rod 7. A gripper 9 is fixedly connected to the tail of the gripper support rod 7. A buffer anti-slip pad 10 is fixedly connected to the gripper 9. When the gripper button 6 is pressed, the micro motor 16 fixedly connected inside the box body 1 starts, and the threaded rod 17 fixedly connected to its output end rotates accordingly. The threaded rod 17 fixedly connected to the threaded rod 17... The slider 18 moves linearly under the drive of the threaded rod 17. The gripper support rod 7, which is fixedly connected around the slider 18, moves together with the slider 18. The reinforcing rib 8, which is fixedly connected on the gripper support rod 7, enhances the structural strength of the support rod and prevents it from deforming under force. The gripper 9, which is fixedly connected at the tail of the gripper support rod 7, clamps the door and window under the drive of the support rod. The buffer anti-slip pad 10, which is fixedly connected on the gripper 9, can prevent the gripper from making hard contact with the door and window and causing damage. At the same time, it can prevent the door and window from sliding during the clamping process and ensure the stability of the positioned hinge.

[0038] A limiting block 19 is fixedly connected to the rear end of the box 1. The limiting block 19 can limit the movement range of the slider 18 and prevent the slider from moving too much, which could damage the gripper support rod 7 or other components.

[0039] Working principle: The operator holds the handles 2 at both ends of the outer side of the box 1 and can judge whether the device is in a horizontal state by the level bubble 4 in the middle part of the box 1. The operator uses the scale 3 on the upper edge of the box 1 to make preliminary size measurement and marking of the hinge installation position, providing basic data for hinge positioning.

[0040] The suction cup 14 and the strong magnet 15, which are cross-fixed on the side of the box 1, are used to fix the device to the surface of the door, window or door frame. When the suction cup 14 is used for fixation, the suction cup button 5 is pressed to control the suction and release of the suction cup 14. The micro vacuum pump 12 fixedly connected inside the box 1 is started, and the vacuum device 13 connected to it works accordingly, so that a negative pressure is formed inside the suction cup 14, thereby firmly adhering to the smooth surface of the door, window or door frame. If the door, window or door frame is made of iron, the strong magnet 15 can be directly adsorbed on it to assist in fixing the device.

[0041] In the hinge clamping and positioning stage, pressing the gripper button 6 starts the micro motor 16 fixedly connected inside the housing 1, and the threaded rod 17 fixedly connected to its output end rotates accordingly. The slider 18 fixedly connected to the threaded rod 17 moves linearly under the drive of the threaded rod 17. The gripper support rod 7 fixedly connected around the slider 18 moves together with the slider 18. The reinforcing rib 8 fixedly connected to the gripper support rod 7 enhances the structural strength of the support rod and prevents it from deforming under force. The gripper 9 fixedly connected to the tail of the gripper support rod 7 clamps the door and window under the drive of the support rod. The buffer anti-slip pad 10 fixedly connected to the gripper 9 can prevent the gripper from making hard contact with the door and window and causing damage, while preventing the door and window from sliding during the clamping process, ensuring the stability of the positioned hinge.

[0042] The limiting block 19 fixedly connected to the tail end inside the box 1 can limit the movement range of the slider 18, preventing excessive movement of the slider from causing damage to the gripper support rod 7 or other components. The heat dissipation hole 11 opened at the bottom of the box 1 can dissipate the heat generated by the micro vacuum pump 12 and micro motor 16 inside the box 1 in time, ensuring that both operate continuously and stably, and ensuring the normal operation of the device.

[0043] Through the coordinated action of the above components, the device achieves precise positioning and fixation of door and window hinges, facilitating hinge installation.

[0044] Structural Description:

[0045] Box 1: Box 1 is the basic load-bearing structure of the device.

As the carrier of the overall structure, it centrally integrates the various functional components, ensuring that the device structure is compact and the layout is reasonable. It provides a stable foundation for the coordinated work of various components and reduces the installation error of scattered components.

[0046] Handle 2: Handle 2 is fixedly connected to both ends of the outer side of the box body 1. It conforms to the ergonomic design, making it easy for the operator to hold the device stably. It reduces hand shaking during positioning and hinge installation, improves operational stability, and provides convenient operating fulcrums for suction cup button 5 and gripper button 6.

[0047] Ruler 3: Ruler 3 is fixedly connected to the upper edge of the box 1. It can directly measure and mark the dimensions of the door and window hinge installation positions without the need to carry additional tools such as tape measures, simplifying the operation process. In addition, the fixed connection with the box 1 ensures the consistency of the measurement benchmark and improves the accuracy of the positioning dimensions.

[0048] Level Bubble 4: Level Bubble 4 is fixedly connected to the middle part of the box body 1 and rigidly connected to the box body 1 to ensure that the horizontal judgment benchmark is consistent with the overall posture of the device. Operators can intuitively observe whether the device is horizontal, avoid the problem of doors and windows not opening and closing smoothly due to the tilt of the hinge installation, and improve the accuracy of the installation level.

[0049] Suction cup button 5: The suction cup button 5 is fixedly connected between the two handles 2 and is located close to the handles 2. This allows the operator to operate the handles 2 simultaneously and directly control the start and stop of the micro vacuum pump 12, enabling the suction cup 14 to quickly adsorb and release, simplifying the fixing operation steps and improving efficiency.

[0050] Gripper button 6: The gripper button 6 is fixedly connected between the two handles 2 and is set in conjunction with the suction cup button 5. The position design of the suction cup button 5 makes it easy to operate when holding. It can control the forward and reverse rotation of the micro motor 16 to realize the clamping and releasing of the gripper 9. The operation logic is clear, reducing the probability of misoperation and improving the convenience of clamping and positioning.

[0051] Gripper support rod 7: The gripper support rod 7 is fixedly connected around the slider 18, and the tail is fixedly connected to the gripper 9. It serves as the connection medium between the slider 18 and the gripper 9, converting the linear motion of the slider 18 into the clamping action of the gripper 9. The surrounding structure design ensures that the gripper 9 is subjected to uniform force, improving clamping stability.

[0052] Reinforcing rib 8: The reinforcing rib 8 is fixedly connected to the gripper support rod 7, which enhances the structural strength and deformation resistance of the gripper support rod 7, prevents the support rod from bending due to excessive force when clamping doors and windows, ensures the positioning accuracy of the gripper 9, and extends the service life of the device.

[0053] Gripper 9: Gripper 9 is fixedly connected to the tail of gripper support rod 7 and directly contacts the door and window to achieve clamping and positioning. The clamping force can be precisely controlled through the linkage of gripper support rod 7 to ensure that the hinge is stable in position during installation and avoid displacement that affects installation accuracy.

[0054] Buffer anti-slip pad 10: The buffer anti-slip pad 10 is fixedly connected to the clamp 9. It is made of flexible material to avoid surface scratches or indentations caused by hard contact between the clamp 9 and the door / window. At the same time, it increases the friction with the door / window to prevent the door / window from sliding during clamping, thus balancing protection and positioning stability.

[0055] Heat dissipation hole 11: The heat dissipation hole 11 is located on the bottom of the box 1 to provide a heat dissipation channel for the miniature vacuum pump 12 and miniature motor 16 inside the box 1, so as to dissipate the heat generated during operation in a timely manner, avoid the equipment performance degradation or damage due to high temperature, and ensure the continuous and stable operation of the device.

[0056] Miniature vacuum pump 12: The miniature vacuum pump 12 is fixedly connected inside the box 1, and the vacuum device 13 is fixedly connected to the top. It serves as the power source for the suction cup 14 to adsorb. The vacuum device 13 extracts the air from the suction cup 14 to form a negative pressure, thereby achieving stable fixation of the device on the smooth surface. The power output is stable, ensuring reliable adsorption force.

[0057] Vacuum device 13: Vacuum device 13 is fixedly connected to the micro vacuum pump 12 and to the suction cup 14. As a connecting bridge between the micro vacuum pump 12 and the suction cup 14, it can stably transmit negative pressure, ensure uniform negative pressure in the suction cup 14, improve the sealing and stability of adsorption, and avoid device displacement caused by air leakage.

[0058] Suction cup 14: The suction cup 14 is fixedly connected to the side of the box 1 and connected to the vacuum device 13. It is adsorbed onto the smooth surface of the door, window or door frame by negative pressure. It works with the micro vacuum pump 12 and the vacuum device 13 to achieve quick fixation. It is suitable for non-magnetic materials such as glass and plastic, thus expanding the applicability of the device.

[0059] Strong magnet 15: The strong magnet 15 is fixedly connected to the side of the box 1 and is distributed crosswise with the suction cup 14. It can be directly adsorbed onto iron doors and windows or door frames, forming a complementary fixing method with the suction cup 14. It is adaptable to magnetic material surfaces, does not rely on negative pressure, and improves the fixing flexibility of the device on different material surfaces.

[0060] Miniature motor 16: The miniature motor 16 is fixedly connected inside the housing 1, and the output end is fixedly connected to the threaded rod 17 to provide power for the clamping action of the gripper 9. By driving the threaded rod 17 to rotate, the slider 18 can be moved accurately. The power output is controllable to ensure the clamping force and position accuracy of the gripper 9.

[0061] Threaded rod 17: The threaded rod 17 is fixedly connected to the output end of the micro motor 16, and the slider 18 is fixedly connected to it. It converts the rotational motion of the micro motor 16 into the linear motion of the slider 18. The threaded transmission has the characteristics of high precision and good self-locking. It can accurately control the moving distance of the slider 18 and ensure the accurate positioning of the gripper 9.

[0062] Slider 18: Slider 18 is fixedly connected to threaded rod 17, and gripper support rod 7 is fixedly connected around it. As an intermediate component for power transmission, it drives gripper support rod 7 to move synchronously under the drive of threaded rod 17. The cooperation between slider 18 and threaded rod 17 ensures smooth movement and avoids gripper 9 shaking and affecting positioning.

[0063] Limiting block 19: The limiting block 19 is fixedly connected to the rear end inside the box 1, limiting the maximum movement distance of the slider 18, preventing the slider 18 from moving excessively and causing the gripper support rod 7 to collide with the internal components of the box 1 or the support rod to deform, thus protecting the internal structure of the device and improving the safety of use.

[0064] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
