Digital projection clock multi-angle projection support adjusting mechanism

Abstract

This utility model relates to the field of adjustment mechanism technology and discloses an adjustment mechanism for a multi-angle projection bracket of a digital display projection clock. The mechanism includes a base with an adjustment component on the top for adjusting the angle. The bracket drives a connecting rod to rotate laterally on a bearing, which in turn drives the insert blocks to rotate sequentially until they align with ten sets of second slots. Then, the restoring force of a first spring causes the slider to slide back to its original position within the movable chamber, inserting the insert blocks into the second slots. This achieves the purpose of adjusting the lateral rotation angle of the digital display projection clock. Furthermore, a rotating rod rotates within a fixed base, causing another set of insert blocks to insert into a corresponding set of first slots, thus achieving the purpose of adjusting the vertical angle of the digital display projection clock. This makes angle adjustment more convenient and faster for operators, while solving the problem of cumbersome adjustment steps in existing bracket adjustment mechanisms.

Description

Technical Field

[0001] This utility model relates to the field of adjustment mechanism technology, specifically to an adjustment mechanism for a multi-angle projection bracket of a digital display projection clock. Background Technology

[0002] In modern life, digital projection clocks, with their ability to clearly project time information onto walls, ceilings, and other surfaces, are widely used in various settings such as bedrooms, living rooms, and offices. They provide convenience for people to check the time, eliminating the need to look directly at the clock itself, but simply at the projected surface.

[0003] Existing projection stands have significant shortcomings in angle adjustment. Some stands use a composite structure of gear meshing and bolt locking. When adjusting, users need to first loosen multiple sets of positioning bolts, then adjust the projection angle tooth by tooth through the gear set, and finally repeatedly tighten the bolts to fix it. The whole process requires frequent tool switching and extremely high adjustment accuracy, which is inconvenient for operators to adjust the stand. Therefore, those skilled in the art provide a multi-angle projection stand adjustment mechanism for digital display projection clocks to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a multi-angle projection bracket adjustment mechanism for a digital display projection clock, thereby solving the problems in the prior art.

[0005] This utility model provides the following technical solution: a multi-angle projection bracket adjustment mechanism for a digital display projection clock, including a base, an adjustment component for adjusting the angle is provided on the top of the base, a bracket is fixedly connected to the top of the adjustment component, a digital display projection clock is placed inside the bracket, and a connecting component for limiting the position of the digital display projection clock is provided between the bracket and the digital display projection clock.

[0006] As a preferred embodiment of the above technical solution, the adjustment component includes a bearing built into the top surface of the base, a connecting rod fixedly connected to the top surface of the bearing, a fixing ring fixedly connected to the base surface around the connecting rod, a fixing seat fixedly connected to the end of the connecting rod away from the fixing ring, a rotating rod rotatably connected inside the fixing seat, a bracket fixedly connected to the top surface of the rotating rod, a digital display projection clock placed on the top of the bracket, a movable chamber fixedly connected to the left outer wall of the connecting rod, a first spring fixedly connected to the inner wall of the movable chamber, a slider fixedly connected to the other end of the first spring, and the slider slides linearly within the movable chamber. Two sets of inserts are symmetrically fixedly arranged on the upper and lower outer walls of the slider. One set of inserts has five sets of first slots opened in the fixing seat and rotating rod corresponding to the outer wall of the outer wall of the insert, and the other set of inserts has ten sets of second slots evenly spaced on the outer wall of the fixing ring corresponding to the outer wall of the fixed ring.

[0007] As a preferred embodiment of the above technical solution, the two sets of inserts are designed in an L-shape, and the right angles on the outer walls of the inserts are all rounded.

[0008] As a preferred embodiment of the above technical solution, one end of the first spring is welded to the middle position of the inner wall of the movable chamber, and the other end of the first spring is welded to the inner end of the slider.

[0009] As a preferred embodiment of the above technical solution, the connecting assembly includes a guide rail formed on the top surface of the bracket, a sliding rod slidably connected within the guide rail, a digital display projection clock fixedly connected to the outer wall of the end of the sliding rod facing away from the bracket, two sets of guide grooves symmetrically formed within the brackets on both sides of the digital display projection clock, a limit block slidably connected within each set of guide grooves, a limit groove formed on the outer wall of the digital display projection clock corresponding to the inner end surface of each set of limit blocks, a pull rod fixedly connected to the outer wall of the end of each set of limit blocks facing away from the limit groove, and a second spring wound around the surface of the pull rod in each set of guide grooves.

[0010] As a preferred embodiment of the above technical solution, a handle is provided on the outer wall of the pull rod away from the limiting block, and the handle is designed in the shape of a square.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a bracket to drive a connecting rod to rotate laterally on a bearing. The connecting rod then drives the insert blocks to rotate sequentially until they align with ten sets of second slots. The restoring force of the first spring causes the slider to slide back to its original position within the movable chamber, inserting the insert blocks into the second slots. This achieves the purpose of adjusting the lateral rotation angle of the digital display projection clock. Furthermore, the rotating rod rotates within the fixed base, causing another set of insert blocks to insert into the corresponding set of first slots, thus achieving the purpose of adjusting the vertical angle of the digital display projection clock. This makes angle adjustment more convenient and faster for operators, while also solving the problem of cumbersome adjustment steps in existing bracket adjustment mechanisms.

[0013] 2. This utility model uses a digital display projection clock to drive a sliding rod into the guide rail, aligning the limiting groove with the limiting block. Then, the restoring force of the second spring is used to drive the limiting block to abut against the limiting groove, thereby facilitating the quick assembly and disassembly of the digital display projection clock by the staff, thus improving the efficiency of the assembly, disassembly and replacement of the digital display projection clock.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a digital display projection clock multi-angle projection bracket adjustment mechanism, including a base 1, an adjustment component 3 for adjusting the angle is provided on the top of the base 1, a bracket 36 is fixedly connected to the top of the adjustment component 3, a digital display projection clock 2 is placed inside the bracket 36, and a connecting component 4 for limiting the position of the digital display projection clock 2 is provided between the bracket 36 and the digital display projection clock 2.

[0022] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the adjustment component 3 includes a bearing 31 built into the top surface of the base 1. A connecting rod 32 is fixedly connected to the top surface of the bearing 31. A fixing ring 33 is fixedly connected to the base 1 around the connecting rod 32. A fixing seat 34 is fixedly connected to the end of the connecting rod 32 away from the fixing ring 33. A rotating rod 35 is rotatably connected inside the fixing seat 34. A bracket 36 is fixedly connected to the top surface of the rotating rod 35. A digital display projection clock 2 is placed on the top of the bracket 36. A movable chamber 37 is fixedly connected to the left outer wall of the connecting rod 32. A first spring 38 is fixedly connected to the inner wall of the movable chamber 37. A slider 39 is fixedly connected to the other end of the first spring 38. The slider 39 slides linearly inside the movable chamber 37. Two sets of inserts 310 are symmetrically fixedly arranged on the upper and lower outer walls of the slider 39. Five sets of first slots 311 are opened in the fixing seat 34 and rotating rod 35 corresponding to the outer wall of one set of inserts 310. Ten sets of second slots 312 are equally spaced on the outer wall of the fixing ring 33 corresponding to the outer wall of the other set of inserts 310.

[0023] Specifically, the bracket 36 drives the connecting rod 32 to rotate laterally on the bearing 31. Then, the connecting rod 32 drives the insert blocks 310 to rotate sequentially until they align with the ten sets of second slots 312. The restoring force of the first spring 38 drives the slider 39 to slide back in the movable chamber 37, and the insert blocks 310 are inserted into the second slots 312, thereby achieving the purpose of adjusting the lateral rotation angle of the digital display projection clock 2. Then, the rotating rod 35 rotates in the fixed base 34, causing another set of insert blocks 310 to be inserted into the corresponding set of first slots 311, thereby achieving the purpose of adjusting the vertical angle of the digital display projection clock 2. This makes it more convenient and faster for staff to adjust the angle, and at the same time solves the problem of cumbersome adjustment steps in the existing bracket adjustment mechanism.

[0024] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the two sets of inserts 310 are designed in an L shape, and the right angles on the outer wall of the inserts 310 are all rounded.

[0025] In practice, this design allows staff to easily pull the insert block 310, which in turn causes the slider 39 to slide within the movable chamber 37, thus facilitating the operation of the slider 39.

[0026] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, one end of the first spring 38 is welded to the middle position of the inner wall of the movable chamber 37, and the other end of the first spring 38 is welded to the inner end of the slider 39.

[0027] Specifically, this implementation ensures that the elastic force generated by the compression of the first spring 38 is evenly transmitted to the slider 39, allowing the slider 39 to slide stably within the movable chamber 37 and preventing it from getting stuck.

[0028] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 as well as Figure 4 As shown, the connecting component 4 includes a guide rail 41 formed on the top surface of the bracket 36. A slide rod 42 is slidably connected in the guide rail 41. A digital display projection clock 2 is fixedly connected to the outer wall of the end of the slide rod 42 away from the bracket 36. Two sets of guide grooves 43 are symmetrically formed in the brackets 36 on both sides of the digital display projection clock 2. Limiting blocks 44 are slidably connected in both sets of guide grooves 43. Limiting grooves 45 are formed on the outer wall of the digital display projection clock 2 corresponding to the inner end surface of the two sets of limiting blocks 44. Pull rods 46 are fixedly connected to the outer wall of the end of the two sets of limiting blocks 44 away from the limiting grooves 45. A second spring 47 is wound on the surface of the pull rods 46 in both sets of guide grooves 43.

[0029] Specifically, the digital display projection clock 2 drives the slide rod 42 into the guide rail 41, aligning the limiting groove 45 with the limiting block 44. Then, the restoring force of the second spring 47 drives the limiting block 44 to abut against the limiting groove 45, thus facilitating the quick assembly and disassembly of the digital display projection clock 2 and improving the efficiency of disassembly, assembly, and replacement. When it is necessary to disassemble the digital display projection clock 2, simply pull the lever 46, causing the lever 46 to drive the limiting block 44 from the limiting groove 45 into the guide groove 43. Then, the digital display projection clock 2 drives the slide rod 42 to slide out of the guide rail 41, thus achieving the purpose of quick disassembly of the digital display projection clock 2.

[0030] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, a handle is provided on the outer wall of the pull rod 46 on the side opposite to the limiting block 44, and the handle is designed in the shape of a square.

[0031] In practice, this design allows staff to easily pull the lever 46, causing the lever 46 to slide the limit block 44 out of the limit groove 45, thereby releasing the rotation limit of the digital display projection clock 2. At the same time, it prevents staff from slipping their hands when using the lever 46.

[0032] Working principle: First, pull the insert 310 away from the connecting rod 32, causing the insert 310 to drive the slider 39 to slide outward in the movable chamber 37, and causing the slider 39 to stretch the first spring 38. Then, rotate the bracket 36 laterally, causing the bracket 36 to drive the connecting rod 32 to rotate on the bearing 31 until the digital display projection clock 2 is rotated to the required angle, and any set of second slots 312 is aligned with the insert 310. Then, by releasing the insert 310, the restoring force of the first spring 38 drives the slider 39 to return to its original position and slide in the movable chamber 37, and the insert 310 is inserted into the second slot 312, thereby achieving the purpose of adjusting the lateral angle of the digital display projection clock 2. Then, by rotating the rotating rod 35 in the fixed seat 34, another set of inserts 310 is inserted into the corresponding set of first slots 311, thereby achieving the purpose of adjusting the vertical angle of the digital display projection clock 2.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
