Description

Technical Field

[0001] This invention relates to the field of touch screen bracket technology, and more particularly to a touch screen bracket with manually adjustable angle. Background Technology

[0002] A touchscreen is an interactive display device that integrates input and output functions. Users can directly operate the screen surface with their fingers or a dedicated stylus to control information devices such as computers, mobile phones, and tablets, thus replacing or supplementing traditional physical keyboards and mice. Its emergence has completely changed the way humans interact with computers, making operation intuitive, natural, and efficient, and is a key technology for the widespread adoption of smartphones and tablets.

[0003] When installing a touchscreen, it is often necessary to use an external bracket to fix it in a specific location or environment for people to operate or view. Usually, the screen needs to be tilted slightly back so that the screen plane is perpendicular to the user's natural downward line of sight. However, people of different ages have certain differences in height, which also leads to certain differences in their viewing angle. Therefore, it is necessary to adjust the angle of the touchscreen to avoid causing users to unconsciously lower or raise their heads, which can lead to cervical strain in the long term. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a touch screen holder with manually adjustable angle.

[0005] The present invention is achieved by the following technical solution: it includes a mounting frame, an angle adjustment mechanism is provided on the mounting frame, a placement mechanism is provided above the angle adjustment mechanism, and a lifting mechanism is provided below the placement mechanism; The angle adjustment mechanism includes a rotating rod, the top of which is fixedly connected to the bottom of the mounting frame. A protective shell is rotatably connected to the outer wall of the rotating rod. A gear plate is fixedly connected to the outer wall of the rotating rod. A telescopic rod is fixedly connected inside the protective shell. A locking block is fixedly connected to the end of the telescopic rod near the gear plate. A first spring is fixedly connected to the side of the locking block away from the gear plate. The end of the first spring away from the locking block is fixedly connected to the inner wall of the protective shell. A rotating shaft is rotatably connected inside the mounting frame. One end of the rotating shaft passes through the outer wall of the mounting frame and extends outward. A worm gear is fixedly connected to the end of the rotating shaft away from the mounting frame. A worm is rotatably connected inside the mounting frame. One end of the worm passes through the outer wall of the mounting frame and extends outward. A first knob is fixedly connected to the end of the worm away from the mounting frame.

[0006] As a further improvement to the above solution, the outer wall of the card block contacts the outer wall of the gear disk, the telescopic rod is located inside the first spring, and the top of the worm gear meshes with the bottom of the worm wheel.

[0007] With the above technical solution, the rotation of the rotating rod will drive the toothed disc to rotate. Since the contact surfaces of the toothed disc and the locking block are both inclined, when the toothed disc rotates, it will push the toothed disc to move towards the telescopic rod, thereby causing the telescopic rod to retract and compress the first spring.

[0008] As a further improvement to the above solution, the placement mechanism includes a placement frame, the inner wall of which is fixedly connected to the outer wall of the rotating rod, and a sliding groove is provided on the placement frame, with a bidirectional threaded rod rotatably connected inside the sliding groove.

[0009] As a further improvement to the above solution, one end of the bidirectional threaded rod penetrates through the outer wall of the placement frame and extends therefrom. A second knob is fixedly connected to the end of the bidirectional threaded rod away from the placement frame. A slider is threadedly connected to the outer wall of the bidirectional threaded rod. The outer wall of the slider is slidably connected inside the slide groove. A limit rod is fixedly connected to the outer wall of the slider.

[0010] With the above technical solution, rotating the second knob clockwise causes the bidirectional threaded rod to rotate. The clockwise rotation of the bidirectional threaded rod causes the two sliders to move closer to each other along the slide groove. The sliders drive the limit rod to move, thereby limiting the external display screen device.

[0011] As a further improvement to the above solution, the lifting mechanism includes a connecting rod, the top end of which is fixedly connected to the bottom of the protective shell, a slot is provided on the connecting rod, a storage tube is slidably connected to the outer wall of the connecting rod, an anti-detachment block is slidably connected inside the storage tube, and the top of the anti-detachment block is fixedly connected to the bottom end of the placement rack.

[0012] As a further improvement to the above solution, a plug rod is slidably connected inside the storage tube. A limit block is fixedly connected to one end of the plug rod near the connecting rod. The side of the limit block away from the plug rod is sleeved inside the slot. A second spring is fixedly connected to the side of the limit block near the plug rod.

[0013] As a further improvement to the above solution, the insertion rod is located inside the second spring, and the end of the second spring away from the limiting block is fixedly connected to the inner wall of the storage tube. The side of the insertion rod away from the limiting block penetrates through the outer wall of the storage tube and extends therefrom. The end of the insertion rod away from the limiting block is fixedly connected to a mounting plate, and the side of the mounting plate away from the insertion rod is rotatably connected to a pull ring. The bottom end of the storage tube is fixedly connected to a bottom plate.

[0014] Using the above technical solution, pulling the pull ring away from the storage tube causes the mounting plate to move, which in turn moves the insertion rod. The insertion rod then moves the limiting block, which in turn compresses the second spring. The movement of the limiting block causes it to disengage from the slot on the connecting rod, at which point the height of the top of the connecting rod can be adjusted.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention involves horizontally moving the mounting bracket, which in turn rotates the rotating rod and the placement mechanism. The rotating rod then rotates the gear disc. Because the contact surfaces of the gear disc and the locking block are both inclined, the rotation of the gear disc pushes it towards the telescopic rod, causing the telescopic rod to retract and compress the first spring. When the groove of the gear disc aligns with the protruding part of the locking block, the locking block is re-engaged into the groove due to the spring force of the first spring. This prevents the gear disc from rotating without external force, thus allowing the display screen fixed to the placement mechanism to rotate for easy adjustment of the screen's orientation. Then, rotating the first knob rotates the worm gear, which in turn rotates the worm wheel, which in turn rotates the rotating shaft. The rotating shaft then rotates the placement mechanism, causing the tilt angle of the display screen on the placement mechanism to change, making the screen plane perpendicular to the user's relatively horizontal line of sight.

[0016] This invention uses a second knob rotated clockwise to rotate a bidirectional threaded rod. The clockwise rotation of the bidirectional threaded rod causes two sliders to move closer to each other along the groove. The sliders then move a limiting rod, thereby limiting the external display screen device and preventing it from falling.

[0017] This invention allows for effective height adjustment of the device by pulling a ring away from the storage cylinder. The ring pushes the mounting plate, which in turn moves the insertion rod, which in turn moves the limiting block. Simultaneously, the second spring is compressed, causing the limiting block to disengage from the slot on the connecting rod. At this point, the connecting rod can be pulled along the storage cylinder. Releasing the ring allows the spring force of the second spring to re-insert the limiting block into the slot, preventing the slot from shifting due to gravity. This effectively adjusts the height of the device to accommodate users of different age groups. Attached Figure Description

[0023] The placement mechanism 3 includes a placement frame 301, the inner wall of which is fixedly connected to the outer wall of the rotating rod 201. A sliding groove 302 is provided on the placement frame 301, and a bidirectional threaded rod 303 is rotatably connected inside the sliding groove 302.

[0024] One end of the bidirectional threaded rod 303 passes through the outer wall of the placement frame 301 and extends therefrom. The end of the bidirectional threaded rod 303 away from the placement frame 301 is fixedly connected to a second knob 304. A slider 305 is threadedly connected to the outer wall of the bidirectional threaded rod 303. The outer wall of the slider 305 is slidably connected inside the slide groove 302. A limit rod 306 is fixedly connected to the outer wall of the slider 305.

[0025] The lifting mechanism 4 includes a connecting rod 401. The top end of the connecting rod 401 is fixedly connected to the bottom of the protective shell 202. A slot 402 is provided on the connecting rod 401. A storage tube 403 is slidably connected to the outer wall of the connecting rod 401. An anti-detachment block 404 is slidably connected inside the storage tube 403. The top of the anti-detachment block 404 is fixedly connected to the bottom end of the placement rack 301.

[0026] The storage tube 403 has a sliding connection to a rod 405. A limiting block 406 is fixedly connected to one end of the rod 405 near the connecting rod 401. The side of the limiting block 406 away from the rod 405 is fitted into the slot 402. A second spring 407 is fixedly connected to the side of the limiting block 406 near the rod 405.

[0027] The insertion rod 405 is located inside the second spring 407. The end of the second spring 407 away from the limiting block 406 is fixedly connected to the inner wall of the storage tube 403. The side of the insertion rod 405 away from the limiting block 406 passes through the outer wall of the storage tube 403 and extends outward.

[0028] The implementation principle of a manually adjustable touchscreen bracket in this application embodiment is as follows: In use, the external display device is placed inside the mounting bracket 301. Then, the second knob 304 is rotated clockwise. The second knob 304 drives the bidirectional threaded rod 303 to rotate. The clockwise rotation of the bidirectional threaded rod 303 causes the two sliders 305 to move closer together along the slide groove 302. The sliders 305 drive the limiting rod 306 to move, thereby limiting the external display device and preventing it from falling. Then, the mounting bracket 1 is moved horizontally, causing the mounting bracket 1 to rotate the rod. When rod 201 and placement mechanism 3 rotate, the rotation of rod 201 will drive the gear 203 to rotate. Since the contact surfaces of gear 203 and locking block 205 are both inclined, when gear 203 rotates, it will push gear 203 towards telescopic rod 204, thereby causing telescopic rod 204 to retract and compress the first spring 206. When the groove of gear 203 aligns with the protrusion of locking block 205, locking block 205 will be locked back into the groove of gear 203 due to the elastic force of the first spring 206. This can prevent gear 203 from rotating without external force, thus fixing the gear 203. The display screen on the placement mechanism 3 is rotated to adjust its orientation. Then, the first knob 210 is rotated, causing the worm gear 209 to rotate. The worm gear 209 rotates the worm wheel 208, which in turn rotates the shaft 207. The shaft 207 then rotates the placement mechanism 3, causing the tilt angle of the display screen on the placement mechanism 3 to change, making the screen plane perpendicular to the user's relatively horizontal line of sight. Then, the pull ring 409 is pulled away from the storage cylinder 403, causing the mounting plate 408 to be pushed. 08 drives the insertion rod 405 to move, which in turn drives the limiting block 406 to move. At the same time, it compresses the second spring 407. The movement of the limiting block 406 causes it to disengage from the slot 402 on the connecting rod 401. At this point, the connecting rod 401 can be pulled along the storage cylinder 403. Then, the pull ring 409 is released. The elastic force of the second spring 407 will cause the limiting block 406 to re-insert into the slot 402, preventing the slot 402 from moving due to gravity. This allows for effective adjustment of the device's height to accommodate users of different age groups.
