Description

Technical Field

[0001] This application relates to the field of handle technology, specifically a metal handle. Background Technology

[0002] Metal handles are tools made of metal used to open and close doors, drawers, cabinets, boxes, and other items. Their main function is to facilitate the opening and closing of doors and drawers and to provide a stable gripping point. Metal handles are usually made of materials such as stainless steel, aluminum alloy, and copper. Due to their high strength, corrosion resistance, and wear resistance, they are widely used in homes, offices, and industries.

[0003] Traditional metal handles always maintain a fixed length. In small environments or where the distance to the wall is tight, the protruding part of the handle often causes space congestion, makes it inconvenient to use, or increases the risk of collision. To solve the above problems, a new type of metal handle has been proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a metal handle with a telescopic design, which can provide greater flexibility and comfort in situations where space is limited, usage scenarios are diverse, and the handle length needs to be adjusted.

[0005] To achieve the above objectives, this application provides the following technical solution: a metal handle, comprising a handle base and a metal outer tube fixedly connected to one end of the handle base, wherein the metal outer tube is provided with a telescopic mechanism, the telescopic mechanism comprising a rectangular metal block slidably sleeved on the inner wall of the metal outer tube, a lead screw rotatably sleeved on the inner wall of the metal outer tube, the inner wall of the rectangular metal block being threadedly connected to the outer surface of the lead screw, a worm gear being fixedly connected to the shaft end of the lead screw, and a worm being rotatably sleeved on the inner wall of the metal outer tube, the worm meshing with the worm gear.

[0006] The above solution, through the telescopic mechanism, enables the device to have convenient telescopic functionality, avoiding excessive space occupation. It is especially suitable for environments with limited space. Furthermore, the telescopic design allows users to adjust the length of the outer metal tube as needed, making the force and angle more tailored to individual habits or requirements, increasing operational comfort. During adjustment, the rectangular metal block extends or retracts from the inner wall of the outer metal tube by rotating the worm gear. The rotation of the worm gear drives the worm wheel, which in turn rotates the lead screw, causing the rectangular metal block to move within the inner wall of the outer metal tube. The worm wheel and worm gear, combined, have a self-locking effect, and the lead screw itself also has a self-locking effect. This double locking effectively prevents the rectangular metal block from extending or retracting arbitrarily, making it more practical.

[0007] Furthermore, a tail block is fixedly connected to one end of the rectangular metal block, and both the outer surface of the metal outer tube and the outer surface of the rectangular metal block are passivated.

[0008] The above solution makes the outer surface of the metal tube and the rectangular metal block more rounded, improving the comfort during use.

[0009] Furthermore, the worm gear's shaft end passes through a metal outer tube and is fixedly connected to a knob, the outer surface of which is coated with an anti-slip layer.

[0010] The above solution increases the contact area at the end of the worm shaft, making it easier to rotate the worm.

[0011] Furthermore, a partition is fixedly connected to the inner wall of the outer metal tube, and the lead screw is rotatably sleeved on the inner wall of the partition.

[0012] The above scheme can limit the position of the rectangular metal block, thus avoiding interference with the rotation of the worm gear and worm during the movement of the rectangular metal block.

[0013] Furthermore, two guide posts are fixedly connected to the outer surface of the partition, and two guide grooves are opened on one side of the rectangular metal block, with the two guide posts slidably sleeved in the two guide grooves respectively.

[0014] The above method enables the rectangular metal block to move stably within the inner wall of the outer metal tube, achieving a stable expansion and contraction effect.

[0015] Furthermore, grooves are provided on both sides of the inner wall of the outer metal tube, and two sliders are fixedly connected to the outer surface of the rectangular metal block. The two sliders are respectively slidably sleeved on the inner walls of the two grooves.

[0016] The above scheme allows the sliding groove and slider to work together to make the rectangular metal block move more stably on the inner wall of the outer metal tube, while also limiting the maximum distance the rectangular metal block extends, thus preventing it from falling off the inner wall of the outer metal tube.

[0017] Furthermore, the handle base has a cavity inside, and an annular block is fixedly connected to the inner wall of the cavity.

[0018] The above scheme allows the device to be fitted into the position to be installed, facilitating subsequent positioning work.

[0019] Furthermore, the bottom of the handle base is provided with an internal thread groove, and the outer surface of the handle base is provided with a positioning hole, which is connected to the cavity.

[0020] The above solution allows for easy positioning and installation of the handle base in a suitable location using the internal threaded groove and positioning hole.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This metal handle features a telescopic mechanism that allows for convenient extension and retraction, minimizing space usage and making it particularly suitable for confined or narrow environments. Users can adjust the length of the outer metal tube by rotating the worm gear to flexibly meet personal preferences or desired force and angle, enhancing operational comfort. When the worm gear rotates, it drives the worm wheel and lead screw, causing the rectangular metal block to extend or retract within the inner wall of the outer metal tube. The worm wheel and worm gear combination is self-locking, and the lead screw itself also has a self-locking function. This double locking mechanism effectively prevents accidental extension and retraction, enhancing the device's practicality. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 3 and Figure 4 This embodiment of a metal handle includes a handle base 1 and a metal outer tube 2 fixedly connected to one end of the handle base 1. The metal outer tube 2 has an internal telescopic mechanism 3, which includes a rectangular metal block 301 slidably sleeved on the inner wall of the metal outer tube 2. The rectangular metal block 301 can extend out of or into the metal outer tube 2, thereby adjusting its length. A lead screw 303 is rotatably sleeved on the inner wall of the metal outer tube 2. The inner wall of the rectangular metal block 301 is threadedly connected to the outer surface of the lead screw 303. When the lead screw 303 rotates, the rectangular metal block 301 can move within the inner wall of the metal outer tube 2. The threaded connection between the lead screw 303 and the rectangular metal block 301 has a self-locking effect, allowing the rectangular metal block 301 to be adjusted to a suitable position and limited. A worm gear 304 is fixedly connected to the shaft end of the lead screw 303. The wall-mounted rotating sleeve is equipped with a worm gear 305, which meshes with a worm wheel 304. When the worm gear 305 rotates, it causes the worm wheel 304 to rotate, which in turn causes the lead screw 303 to rotate. This allows adjustment of the extended length of the rectangular metal block 301, avoiding excessive space occupation. This is especially suitable for confined or narrow environments. Furthermore, by adjusting the extended length of the rectangular metal block 301, users can adjust the length of the outer metal tube 2 as needed, making the force and angle more suitable for personal habits or needs, increasing operational comfort. At the same time, the combination of the worm wheel 304 and the worm gear 305 has a self-locking effect, which, together with the self-locking effect of the lead screw 303 itself, achieves a double locking effect. This allows the rectangular metal block 301 to be locked more stably after being adjusted to a suitable position, preventing the rectangular metal block 301 from moving arbitrarily.

[0032] Please see Figure 2 , Figure 4 and Figure 5A tail block 302 is fixedly connected to one end of a rectangular metal block 301. Both the outer surfaces of the outer metal tube 2 and the rectangular metal block 301 are passivated, making them more rounded and improving user comfort. A knob 306 is fixedly connected to the shaft end of the worm gear 305, which passes through the outer metal tube 2. The outer surface of the knob 306 is coated with an anti-slip layer, increasing the contact area at the shaft end of the worm gear 305 and facilitating its rotation. Positioning the knob 306 on the back of the outer metal tube 2, close to the handle base 1, prevents accidental rotation. A partition 307 is fixedly connected to the inner wall of the outer metal tube 2. The lead screw 303 is rotatably sleeved on the inner wall of the partition 307, limiting the movement of the rectangular metal block 301 and preventing it from damaging the worm gear 304 during movement. The rotation of the worm gear 305 causes interference. Two guide posts 308 are fixedly connected to the outer surface of the partition 307. Two guide grooves 309 are opened on one side of the rectangular metal block 301. The two guide posts 308 are slidably sleeved in the two guide grooves 309, which enables the rectangular metal block 301 to move stably in the inner wall of the outer metal tube 2, achieving a stable telescopic effect. Slide grooves 310 are opened on both sides of the inner wall of the outer metal tube 2. Two sliders 311 are fixedly connected to the outer surface of the rectangular metal block 301. The two sliders 311 are slidably sleeved in the inner wall of the two slide grooves 310. The slide grooves 310 and sliders 311 cooperate with each other to enable the rectangular metal block 301 to move more stably in the inner wall of the outer metal tube 2. At the same time, it can also limit the maximum distance of the rectangular metal block 301 to extend, preventing the rectangular metal block 301 from falling out of the inner wall of the outer metal tube 2.

[0033] Please see Figure 1 and Figure 2 The handle base 1 has a cavity 4 inside, and an annular block 5 is fixedly connected to the inner wall of the cavity 4. The cavity 4 and the annular block 5 allow the device to be fitted into the position to be installed, facilitating subsequent positioning. The bottom of the handle base 1 has an internal threaded groove 6, and the outer surface of the handle base 1 has a positioning hole 7, which communicates with the cavity 4. The internal threaded groove 6 and the positioning hole 7 allow the handle base 1 to be easily positioned and installed in a suitable position. In summary, the cavity 4, the annular block 5, the internal threaded groove 6, and the positioning hole 7 allow the handle base 1 to be conveniently and stably positioned and installed in a suitable position, making it convenient to use.

[0034] In this embodiment, a metal handle, through a telescopic mechanism 3, enables the device to extend and retract conveniently, avoiding excessive space occupation. It is particularly suitable for confined or narrow environments. Furthermore, the telescopic design allows users to adjust the length of the outer metal tube 2 as needed, making the force and angle more tailored to individual habits or requirements, increasing operational comfort. During adjustment, the worm gear 305 can be rotated to extend or retract the rectangular metal block 301 from the inner wall of the outer metal tube 2. When the worm gear 305 rotates, it drives the worm wheel 304 to rotate, which in turn causes the lead screw 303 to rotate, thus moving the rectangular metal block 301 within the inner wall of the outer metal tube 2. The worm wheel 304 and worm gear 305 together have a self-locking effect, and the lead screw 303 itself also has a self-locking effect. This double locking effectively prevents the rectangular metal block 301 from extending or retracting arbitrarily, making it more practical.

[0035] The working principle of the above embodiment is as follows: The handle base 1 is positioned and installed in a suitable position through the cavity 4, the annular block 5, the internal thread groove 6, and the positioning hole 7. Then, the length of the rectangular metal block 301 extending from the outer metal tube 2 can be adjusted according to the user's usage habits and the available space. When adjusting the position of the rectangular metal block 301, it can be achieved by rotating the knob 306. When the knob 306 rotates, it drives the worm gear 305 to rotate. When the worm gear 305 rotates, it drives the worm wheel 304 to rotate. The rotation of the worm wheel 304 causes the lead screw 303 to rotate. When the lead screw 303 rotates, it causes the rectangular metal block 301 to move within the inner wall of the outer metal tube 2. At the same time, it can be adjusted by the set... The guide post 308 and guide groove 309 improve the stability of the rectangular metal block 301 during movement. The slide groove 310 and slider 311 limit the maximum extension distance of the rectangular metal block 301, preventing the rectangular metal block 301 from accidentally falling out of the inner wall of the outer metal tube 2. After adjusting the rectangular metal block 301 to the appropriate position, the knob 306 can be stopped. Since the worm gear 304 and worm 305 have a self-locking effect, and the lead screw 303 also has a self-locking effect, the rectangular metal block 301 can be positioned in the adjusted position through double locking, preventing random movement. This makes it more practical. The telescopic function not only saves space but also improves the operating experience and increases the applicability of the device.
