Description

Technical Field

[0001] This utility model relates to the field of conference all-in-one machine technology, specifically a conference all-in-one machine that is easy to adjust. Background Technology

[0002] A conference all-in-one machine, also known as a conference tablet all-in-one machine or a smart conference all-in-one machine, is a smart office device that integrates functions such as display, writing, collaboration, and video conferencing.

[0003] When using a conference all-in-one machine, the height of the machine usually needs to be adjusted to meet writing and other needs. However, the existing height adjustment mechanism of the conference all-in-one machine is relatively complicated and inconvenient to adjust.

[0004] CN214331986U discloses a conference tablet all-in-one machine based on a height adjustment mechanism. By setting a base plate, a fixed guide tube, a lifting rod, and a lifting plate, the height of the lifting plate is adjustable, providing a height adjustment function. By setting a connecting plate, a partition, an A-locking box, an A-sliding piece, an A-spring, a snap-fit ​​plate, a snap-fit ​​groove, and a Z-shaped handle, when the height of the lifting plate needs to be adjusted, simply squeeze the two Z-shaped handles simultaneously to adjust the height of the lifting plate. After adjustment, simultaneously releasing the Z-shaped handles allows the snap-fit ​​plate to lock automatically in the snap-fit ​​groove, thus providing convenient adjustment and automatic locking functions.

[0005] However, the height adjustment mechanism in the CN214331986U patent is still complex. It requires one hand to operate the Z-shaped handle and the other hand to lift the integrated machine to move it up and down. The integrated machine is usually large and heavy, making it difficult to lift and move it with one hand. It may even require two people to operate the lifting integrated machine together, which is very inconvenient. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model provides an easily adjustable conference all-in-one machine.

[0007] The technical solution of this utility model is as follows:

[0008] An easily adjustable conference all-in-one machine includes a body and a frame, which are connected by a rotating locking mechanism;

[0009] The rotary locking mechanism includes a sliding component, a connecting component, and a cam. The sliding component is slidably connected to the frame and can slide vertically. The connecting component is fixedly connected to the upper rear side of the machine body and rotatably connected to the sliding component. The axis of rotation extends left and right. The cam is connected to the connecting component and rotates coaxially with the connecting component. It is configured such that when the machine body rotates backward to a vertical position, the cam presses against the frame.

[0010] The rotating locking mechanism also includes a plug and several slots. The plug is located at the lower rear side of the machine body and extends backward. Several slots are opened on the frame and are evenly distributed vertically for the plug to be inserted and fitted.

[0011] When the height of the machine body needs to be adjusted, lift the bottom of the machine body forward, pull the insert out of the slot, and at the same time the cam rotates to release the clamping relationship with the frame. At this time, the machine body can be moved up and down freely.

[0012] Once the desired position is reached, rotate the lower part of the machine body backward so that the insert bar is inserted into the corresponding slot. At the same time, the cam rotates and presses against the frame. The machine body is supported by the insertion and engagement of the insert bar and the slot. Meanwhile, the large friction between the cam and the frame also provides support for the machine body, thus firmly locking the position of the machine body.

[0013] When adjusting the height of the conference all-in-one machine, only the lower part of the machine needs to be lifted, without any other operation. The adjustment can be completed by a single person, making it simple and convenient to operate. Moreover, it allows one person to move the machine with both hands, making the height adjustment operation easier.

[0014] Furthermore, the frame includes two vertical guide columns arranged on the left and right, with a base connected to the lower end of the two guide columns. There are two sets of rotating locking mechanisms, corresponding to the two guide columns respectively.

[0015] Furthermore, the two sets of rotating locking mechanisms are arranged symmetrically on the left and right sides.

[0016] Furthermore, the connecting component includes an extension and a rotating shaft fixed to the extension. The extension is fixed to the machine body, the sliding component is rotatably connected to the rotating shaft, and the cam is fixedly connected to the rotating shaft.

[0017] Furthermore, the guide post is a rectangular tube, and the sliding component is located inside the guide post and slides within the inner hole of the guide post. The sliding component is also rectangular tube with its opening facing the front-to-back direction. The side wall of the guide post has slots for the rotating shaft to pass through and slide. The cam is located inside the sliding component. The placement of the sliding component and the cam inside the sliding component makes the overall appearance of the all-in-one machine simpler and avoids occupying external space on the guide post. This allows the center of gravity of the machine to be closer to the guide post, resulting in better and more stable support.

[0018] Furthermore, the cam is an elliptical cam, with its central axis collinear with the axis of rotation. The elliptical cam can simultaneously press against the front and rear side walls of the guide post to increase the friction between the cam and the guide post, thereby increasing the support force on the machine body.

[0019] Furthermore, the sliding component has a wear-resistant plate inside the tube, which slides in fit with the inner hole of the sliding component and is located between the side walls of the cam and the guide post.

[0020] Furthermore, the insert is an arc-shaped strip, and the slot is an arc-shaped groove. The center lines of both the insert and the slot are collinear with the rotation axis of the connecting component. Both the insert and the slot are arc-shaped to ensure a tight fit, allowing the slot to support the insert and thus the machine body. At the same time, the side of the insert fits against the inner side of the slot, generating friction to prevent the insert from being pulled out of the slot by accident, thus avoiding accidental removal of the insert.

[0021] To further prevent the connector from being pulled out due to collisions, the slot is designed as a through hole, with the rear end of the connector extending through a guide post. The rear end of the connector also has a pin hole into which a locking pin is inserted to lock the connector in the slot.

[0022] Furthermore, the horizontal and vertical dimensions of the slot holes are smaller than the corresponding dimensions of the wear-resistant sheet.

[0023] This utility model provides an easy-to-adjust conference all-in-one machine. When adjusting the height of the machine, only the lower part of the machine needs to be lifted or lowered. No other operation is required, and a single person can complete the adjustment. The operation is simple and convenient, and one person can move the machine with both hands, making the height adjustment operation easier. Attached Figure Description

[0032] like Figure 1 and Figure 2As shown, this utility model embodiment provides an easily adjustable conference all-in-one machine (hereinafter referred to as the all-in-one machine), including a body 1 and a frame 2, which are connected by a rotation locking mechanism;

[0033] The rotating locking mechanism includes a sliding component 31, a connecting component 32, and a cam 33. The sliding component 31 is slidably connected to the frame 2 and can slide vertically. The connecting component 32 is fixedly connected to the upper rear side of the body 1 and rotatably connected to the sliding component 31. The axis of rotation extends left and right. The cam 33 is connected to the connecting component 32 and rotates coaxially with the connecting component 32. It is configured such that when the body 1 rotates backward to a vertical position, the cam 33 presses against the frame 2.

[0034] The rotating locking mechanism also includes a plug 34 and several slots 35. The plug 34 is located at the lower rear side of the body 1 and extends rearward. Several slots 35 are opened on the frame 2 and are evenly distributed vertically for the plug 34 to be inserted and engaged.

[0035] Specifically, such as Figure 1 As shown, the frame 2 includes two vertical guide columns 21 arranged on the left and right. The lower ends of the two guide columns 21 are connected to the base 22. There are two sets of rotating locking mechanisms, which correspond to the two guide columns 21 respectively.

[0036] In this embodiment, two sets of rotating locking mechanisms are symmetrically arranged on the left and right sides of the vertical center plane of the body 1 to provide balanced support for the body 1.

[0037] like Figure 2 As shown, the connecting component 32 includes an extension 321 and a rotating shaft 322 fixed to the extension 321. The extension 321 is fixed to the body 1 and extends rearward. The sliding component 31 is rotatably connected to the rotating shaft 322, and the cam 33 is fixedly connected to the rotating shaft 322. The extension 321 provides space for the rotation of the body 1, allowing the insert 34 to be pulled out of the slot 35, while preventing the top of the body 1 from colliding with the guide post 21.

[0038] Please combine Figures 1 to 5 As shown, the guide post 21 is a rectangular tube, preferably a square tube. The sliding component 31 is located inside the guide post 21, and it is also a rectangular tube, preferably a square tube. The four horizontal sides of the sliding component 31 are close to the four inner sides of the guide post 21, so that the sliding component 31 slides in contact with the inner hole of the guide post 21, and the inner hole of the guide post 21 guides the sliding component 31.

[0039] The opening of the sliding component 31 faces the front-to-back direction. The side wall of the guide post 21 is provided with a slot 211 for the rotating shaft 322 to pass through and slide. The cam 33 is located inside the sliding component 31. When the rotating shaft 322 rotates, the cam 33 presses against the front and / or rear side wall of the guide post 21.

[0040] In this embodiment, the sliding component 31 is located inside the guide column 21, and the cam 33 is located inside the sliding component 31, making the overall appearance of the all-in-one machine simpler and avoiding occupying the external space of the guide column 21. This allows the center of gravity of the machine body 1 to be closer to the guide column 21, resulting in better and more stable support.

[0041] In this embodiment, the slot 211 is opened on the opposite side of the two guide posts 21, the two extensions 321 are located between the two guide posts 21, and the rotating shafts 322 on the two extensions 321 extend from the rear end of the extensions 321 in opposite directions to the left and right, pass through the slot 211 and are rotatably connected to the sliding member 31.

[0042] Specifically, such as Figure 3 and Figure 4 As shown, the cam 33 is preferably an elliptical cam 33, whose central axis is collinear with the axis of the rotating shaft 322. When the rotating shaft 322 rotates, the elliptical cam 33 can press against the front and rear side walls of the guide post 21 simultaneously to increase the friction between the cam 33 and the guide post 21. The position of the machine body 1 is locked by the friction, and the support force on the machine body 1 is also increased by increasing the friction.

[0043] Furthermore, the sliding component 31 has a wear-resistant plate 36 inside its tube. The wear-resistant plate 36 is slidably engaged with the inner hole of the sliding component 31 and is located between the cam 33 and the side wall of the guide post 21. When the cam 33 rotates, it presses the wear-resistant plate 36 against the side wall of the guide post 21. Through the wear-resistant plate 36, the contact area with the side wall of the guide post 21 is increased, thereby improving the friction.

[0044] In addition, since the wheel surface of cam 33 is in line contact with the pressing surface when it is pressed, the contact area is small and it is very easy to wear and slip over a long period of use, which reduces the support effect on the machine body 1. In this embodiment, by setting a wear-resistant plate 36, the wear-resistant plate 36 slides with the inner hole of the sliding component 31. The friction between the wear-resistant plate 36 and the side wall of the guide post 21 is transmitted to the sliding component 31 through the wear-resistant plate 36, and then transmitted to the rotating shaft 322 by the sliding component 31 to provide support force for the machine body 1. When cam 33 presses the wear-resistant plate 36, there is no friction problem between cam 33 and wear-resistant plate 36, which reduces the wear of the wheel surface of cam 33.

[0045] like Figure 3 and Figure 5 As shown, in this embodiment, the insert 34 is an arc-shaped strip and the slot 35 is an arc-shaped groove. The center lines of the insert 34 and the slot 35 are both collinear with the rotation axis of the connecting component 32.

[0046] Both the insert 34 and the slot 35 are designed to be curved so that they can fit together tightly, allowing the slot 35 to support the insert 34, thereby supporting the body 1. At the same time, the side of the insert 34 is in contact with the inner side of the slot 35, generating friction to prevent the insert 34 from being pulled out of the slot 35 at will, thus avoiding accidental collision that could cause the insert 34 to be pulled out.

[0047] Furthermore, to prevent the insert 34 from being pulled out due to a collision with the main body 1, the slot 35 is designed as a through hole, with the rear end of the insert 34 extending through the guide post 21. The rear end of the insert 34 also has a pin hole 37, into which a locking pin 38 is inserted, thereby locking the insert 34 within the slot 35. Figure 1 , Figure 2 and Figure 5 As shown.

[0048] Furthermore, a pin hole 37 and a locking pin 38 can be provided on a plug 34 so that the locking of the plug 34 can be quickly released when the height of the body 1 needs to be adjusted.

[0049] In addition, in this embodiment, the horizontal and vertical dimensions of the hole in the slot 35 are smaller than the corresponding dimensions of the wear-resistant piece 36, so as to prevent the wear-resistant piece 36 from falling out of the hole in the slot 35 when it slides vertically with the sliding member 31.

[0050] Furthermore, the distance between the insert 34 and the connecting member 32 above it is set such that when the insert 34 is inserted into the slot 35, the cam 33 is positioned between adjacent slots 35.

[0051] When the height of the machine body 1 needs to be adjusted, the locking pin 38 is pulled out, the bottom of the machine body 1 is lifted forward, the insert 34 is pulled out of the slot 35, and at the same time the cam 33 rotates to release the clamping relationship with the frame 2. At this time, the machine body 1 can be moved up and down freely.

[0052] After the body 1 is moved to the desired position, the lower part of the body 1 is rotated backward so that the insert 34 is inserted into the corresponding slot 35. At the same time, the cam 33 rotates and presses against the frame 2. At this time, the body 1 is supported by the insertion and cooperation of the insert 34 and the slot 35. At the same time, the large friction between the cam 33 and the frame 2 also provides support for the body 1, thereby firmly locking the position of the body 1. Finally, the locking pin 38 is inserted into the pin hole 37 to lock the insert 34.

[0053] When adjusting the height of the machine body 1, the integrated machine of this utility model only requires lifting and placing the lower part of the machine body 1. No other operation is required, and a single person can complete the adjustment action. The operation is simple and convenient, and one person can move the machine body 1 with both hands, making the height adjustment operation easier.
