Description

Technical Field

[0001] The present invention relates to the field of computer risers, and in particular to a desktop mobile riser that locks immediately when released. Background Art

[0002] Most existing Apple desktop computers are of an integrated structure. In order to look simple and fashionable, the configured brackets can usually only be adjusted in pitch, and cannot be adjusted in height, left and right, front and back, etc. In addition, there is also a stand - foot type desktop monitor bracket, which also cannot move back and forth, but is a little better than Apple's, and can usually be adjusted up and down and moved left and right. However, although left - right movement can be achieved, there are still the following problems: 1. The moving structure usually uses four ordinary universal wheels to achieve movement. When reverse movement is required, the universal wheels will rotate and turn in place on the desktop, resulting in laborious movement, a problem of jamming, and at the same time, it is easy to scratch the desktop, and locking and unlocking are also rather troublesome; 2. After moving to a fixed position, braking is very inconvenient and is also easy to forget, which may lead to accidents and cause damage to the computer; 3. The biggest problem with currently higher - end arbitrarily adjustable and hoverable monitor brackets is that they take up a lot of space and are not convenient to install. There are usually two installation methods: one is to drill holes in the desktop and the bracket is fixed through this hole, which is not suitable for desktop drilling in many occasions; the other is to clamp the bracket on the edge of the desktop through a clamping device. In many cases, the table edge is surrounded by office partitions, and it is simply impossible to find a place to clamp, resulting in nowhere to place the bracket.

[0003] Therefore, there are defects in the prior art and improvement is needed. Summary of the Invention

Detailed implementation manners

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Please refer to Figures 1-7, the present invention provides a desktop mobile riser that locks immediately when released, comprising: a support frame 1, two sets of moving members 2 mounted on the support frame 1, a brake block 3, and a lifting driving member 4 connected to the brake block 3. Each of the two sets of moving members 2 includes a plurality of moving wheels 20; specifically, the support frame 1 includes: a support plate, and two side plates respectively connected to both sides of the support plate. The two sets of moving members 2 are respectively mounted on the two side plates and are symmetrically arranged; specifically, in this embodiment, the moving wheels 20 are bull's-eye universal wheels; the brake block 3 is used to contact the placement surface where the support frame 1 is placed and prevent the moving member 2 from moving on the placement surface where the support frame 1 is placed; the lifting driving member 4 is used to drive the brake block 3 to move towards or away from the side of the placement surface where the support frame 1 is placed; when the lifting driving member 4 drives the brake block 3 to move away from the side of the placement surface where the support frame 1 is placed, manually push the support frame 1, and under the action of the two sets of moving members 2, the support frame 1 can be driven to translate. Fix the computer on the support frame 1. When it is necessary to drive it to move left and right, under the action of the lifting driving member 4, drive the brake block 3 to move away from the side of the placement surface where the support frame 1 is placed, so that the brake block 3 is separated from the placement surface. At this time, directly push the support frame 1, and under the action of the moving wheels 20 in the moving member 2, directly drive the entire support frame 1 to move horizontally. After moving it to the designated position, under the action of the lifting driving member 4, drive the brake block 3 to move towards the side close to the placement surface where the support frame 1 is placed, and the bottom of the brake block 3 contacts the placement surface, generating a fixed frictional force, so that the moving wheels 20 cannot move further, thereby realizing moving the support frame 1 and the computer to the designated position; it should be noted that since there is a computer above the brake block 3 and the support frame 1 itself, the total downward pressure after braking can reach 6-8 kg, which can limit the uncontrolled movement of the mobile rack, so that after moving to the fixed position, it will not move further, ensuring high stability, without the need for unlocking and locking operations, simplifying the operation process. At the same time, since there is no need for unlocking and locking operations, there is no problem of forgetting to lock. After adjusting the position each time, when the applied external force disappears, the brake block 3 can be directly lowered, which will not cause an accident and prevent damage to the computer, with high safety; on the other hand, since the support frame 1 in the present invention is directly placed on the desktop, it does not need to be fixed or installed, effectively simplifying the use process. At the same time, it occupies a small space and can be applied to various use environments; in addition, during the movement process, the brake block 3 is separated from the placement surface, so it will not cause damage to the placement surface or the support frame 1 itself, preventing the problem of scratching the placement surface.

[0031] Specifically, in this embodiment, the brake block 3 includes: a brake rubber pad 30, a protective cover 31 sleeved on the brake rubber pad 30, and a brake spring 32 disposed within the protective cover 31. One end of the brake spring 32 abuts against the inner wall of the protective cover 31, and the other end abuts against the brake rubber pad 30. It should be noted that the bottom surface of the brake rubber pad 30 is a non-slip rough surface; the lifting drive member 4 includes: a rotation synchronization member 40, two moving drive gears 41 sleeved on the rotation synchronization member 40, and a lifting moving member 422 that cooperates with the moving drive gears 41; the rotation synchronization member 40 includes: two moving handles 400, a first rotating rod 401, a first synchronization gear box 402 connected to the first rotating rod 401, a synchronization connecting rod 403 connected to the first synchronization gear box 402, a second synchronization gear box 404 connected to the synchronization connecting rod 403, and a second rotating rod 405 connected to the second synchronization gear box 404. The two moving handles 400 are respectively connected to the first rotating rod 401 and the second rotating rod 405, and the first rotating rod 401 is connected to the moving handle 400 through a universal joint 407 to ensure the normal progress of the rotation process; the two moving drive gears 41 are respectively sleeved on the first rotating rod 401 and the second rotating rod 405; the lifting moving member 422 includes: a moving plate 420, a carrying pole 421 connected to the moving plate 420, and a brake pull rod 422 connected to the carrying pole 421. A sawtooth rack 423 that cooperates with the moving drive gears 41 is provided on the moving plate 420; the brake pull rod 422 is connected to the brake rubber pad 30, and the brake spring 32 is sleeved on the brake pull rod 422; a sliding groove 10 is further provided on the support frame 1, and a sliding block 424 that cooperates with the sliding groove 10 is provided at the bottom of the moving plate 420; a return torsion spring 406 is further provided on the moving handle 400. The support frame 1 is sleeved on the moving handle 400, and one end of the return torsion spring 406 is connected to the moving handle 400, and the other end is connected to the support frame 1. Therefore, after releasing the moving handle 400, it can quickly achieve automatic reset under the action of the return torsion spring 406, without generating a virtual position at its rotating part, enabling it to return to the initial position.The specific process of the lifting drive member 4 driving the brake block 3 to move is as follows: Rotate two moving handles 400 simultaneously or rotate one of the moving handles 400, which drives the first rotating rod 401 to rotate. Under the action of the first rotating rod 401, the first synchronous gearbox 402, the synchronous connecting rod 403, and the second synchronous gearbox 404, the second rotating rod 405 is driven to rotate. Further, under the rotating action of the first rotating rod 401 and the second rotating rod 405, the two moving drive gears 41 are driven to rotate. The moving drive gears 41 act on the saw teeth 423 on the moving plate 420, driving the sliding block 424 on the moving plate 420 to slide in the sliding groove 10. The moving plate 420 moves up and down relative to the support frame 1, thereby pulling the carrying pole 421 and the brake pull rod 422 to move. Under the action of the brake pull rod 422, the brake rubber pad 30 is further driven to move away from the placement surface of the support frame 1. The brake spring 32 provided on the brake rubber can play a buffering role during its movement. When the support frame 1 is moved to the designated position, release the moving handle 400. Under the action of the return torsion spring 406, the moving handle 400 can be quickly reset, thereby driving the first rotating rod 401, the first synchronous gearbox 402, the synchronous connecting rod 403, the second synchronous gearbox 404, and the second rotating rod 405 to act in the reverse direction, thereby realizing the quick reset of the brake block 3; Under the action of the rotating synchronizing member 40, the two groups of moving drive gears 41 and the lifting moving member 422 can act synchronously. Therefore, the position adjustment of the computer and the support frame 1 can be realized with one hand operation, effectively simplifying the adjustment process.

[0032] Specifically, in this embodiment, the first synchronous gearbox 402 includes: a box body 4020, a first gear 4021 sleeved on the first rotating rod 401, and a second gear 4022 meshed with the first gear 4021. The second gear 4022 is sleeved on the synchronous connecting rod 403. The structure of the second synchronous gearbox 404 is the same as that of the first synchronous gearbox 402. The synchronous connecting rod 403 is connected to the first gear 4021 in the second synchronous gearbox 404, and the second rotating rod 405 is connected to the second gear 4022 in the second synchronous gearbox 404. Under the action of the first rotating rod 401, the first gear 4021 is driven to rotate. The first gear 4021 drives the second gear 4022 to rotate. Further, under the action of the second gear 4022, the synchronous rod is driven to rotate. Similarly, under the action of the second synchronous gearbox 404, the second rotating rod 405 is driven to rotate.

[0033] Specifically, in this embodiment, an elastic buffer block 21 is provided between the moving wheel 20 and the support frame 1. The elastic buffer block 21 is made of an elastic material. Since the moving wheel 20 is relatively hard and the placement surface may not be very flat, some of the moving wheels 20 may not contact the tabletop or the contact pressure of individual moving wheels 20 may be relatively large. Under the action of the elastic buffer block 21, these effects can be eliminated, vibrations can be isolated, and noise can be reduced.

[0034] Specifically, in this embodiment, two sets of mounting and fixing members 5 are symmetrically arranged on the support frame 1. The mounting and fixing members 5 include: a fixing block 50, a fixing knob 51 threadedly connected to the fixing block 50, and a pressing block 52 sleeved on the fixing knob 51. The two mounting and fixing members 5 are used to fix the base at the bottom of the computer to the support frame 1 of the present invention. When fixing, the computer is directly placed on the support frame 1, the pressing block 52 is rotated, the pressing block 52 presses on the base of the computer, and the fixing knob 51 is rotated. The fixing knob 51 locks the pressing block 52 and the fixing block 50, thereby fixing the computer to the support frame 1 and realizing its quick installation and fixing.

[0035] In summary, the present invention provides a desktop mobile heightening stand that locks immediately when released, having the following beneficial effects:

[0036] 1. There is no need to perform unlocking and locking operations, which simplifies the operation process. There is no problem of forgetting to lock. After each adjustment of the position and the external force applied disappears, the brake block can be directly lowered, which will not cause accidents and prevent damage to the computer, and has high safety;

[0037] 2. The support frame is directly placed on the tabletop without the need for its fixation or installation, and can be applicable to various use environments, with strong compatibility;

[0038] 3. During the moving process, the brake block is separated from the placement surface, and will not cause damage to the placement surface or the support frame itself, avoiding the problem of scratching the placement surface;

[0039] 4. Under the action of the rotation synchronizing member, the synchronous action of the two sets of moving drive gears and the lifting and moving members can be realized, and the position adjustment of the computer and the support frame can be realized with a single-handed operation, effectively simplifying the adjustment process.

[0040] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
