Description

Technical Field

[0001] This utility model relates to the field of table technology with adjustable desktop height, specifically a dust cover for the uprights of a height-adjustable table. Background Technology

[0002] A table is a common piece of furniture, with a flat surface on top and supports underneath. It can be used for placing things, doing things, eating, writing, working, etc. It has a smooth flat surface and is fixed by legs and other supports. In language, it can also be used as a noun. To cater to the needs of the public, there are many types of tables. Tables can be divided into many categories according to needs, such as office desks, dining tables, school desks, computer desks, lecterns, etc. Because the height of people who use tables is different, the optimal table height for each person is also different. In order to make everyone comfortable when using a table, height-adjustable desks have appeared on the market. Height-adjustable desks can automatically adjust the desktop height according to the user's needs to meet the needs of people of different heights.

[0003] When using a height-adjustable desk, the tabletop needs to rise and fall, so the desk's uprights have a lifting mechanism, and motors are installed in the legs. To prevent dust from entering the interior of the uprights through the lifting mechanism's connection points, dust covers are usually inserted at these connections. These dust covers keep the dust out of the uprights. However, when the lifting mechanism rises and falls, friction causes the dust covers to also be subjected to the forces of rising and falling. This can cause the dust covers to loosen when the uprights rise, eventually causing them to fall off the connection points and become unable to keep out dust. This makes the dust covers rather inconvenient to use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a dust cover for the column of a height-adjustable desk. It has the function of ensuring that the dust cover is tightly connected to the lifting structure and will not fall off when the column rises. This eliminates the need for staff to frequently reinstall the dust cover at the connection point, reducing the inconvenience of using the dust cover.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust cover for a height-adjustable table column, comprising a height-adjustable outer shell, wherein a height-adjustable column is slidably connected inside the height-adjustable outer shell, the upper side of the height-adjustable column extends out of the upper side of the height-adjustable outer shell, and a motor is fixedly connected to the upper side of the height-adjustable column;

[0008] The lifting housing has a connecting ring inside, which is sleeved on the outer surface of the lifting column. A dustproof cover is fixedly connected to the upper side of the connecting ring, and the dustproof cover is located on the upper side of the lifting housing.

[0009] The lifting housing and the connecting ring are equipped with a snap-fit ​​mechanism, which enables the connecting ring and the lifting housing to be tightly connected.

[0010] Preferably, the locking mechanism includes a connection port, which is located on the right side of the lifting housing;

[0011] The left wall of the connection port extends into the interior of the lifting housing, and connection grooves are provided on both the front and rear walls of the connection port.

[0012] Preferably, the connecting groove is disposed inside the lifting housing, and a sliding block is slidably connected inside the connecting port;

[0013] The sliding block is fixedly connected to both the front and rear sides with connecting blocks, and the two connecting blocks extend into the interior of the two connecting grooves respectively.

[0014] Preferably, the left side of the lifting housing also has a connection port, the connection structures of the left and right connection ports are the same and mirrored, and the right side of the connecting ring has a sliding groove.

[0015] Preferably, a snap-fit ​​block is slidably connected inside the sliding groove. The snap-fit ​​block is triangular in shape with its inclined surfaces facing the right and the bottom. A connecting spring is fixedly connected to the left side of the snap-fit ​​block.

[0017] The left side of the connecting ring also has a sliding groove, and the connection structure of the sliding grooves on the left and right sides is the same and they are mirror images of each other.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a dust cover for the upright column of a height-adjustable desk, which has the following beneficial effects:

[0020] (1) The dust cover for the column of the lifting table is installed by fitting the top of the dust cover and the connecting ring onto the outer surface of the lifting column and connecting it to the inner surface of the lifting shell. At this time, the snap-fit ​​block extends into the inside of the connection port and forms a snap-fit ​​with the connection port. When the lifting column moves upward, the connecting ring moves upward due to friction. Because the snap-fit ​​block extends into the inside of the connection port and forms a snap-fit, the connecting ring will not be pulled upward by the lifting column and thus will not fall off. This way, the dust cover can be tightly connected to the column and will not fall off due to the column rising. This eliminates the need for staff to frequently reinstall the dust cover at the connection point and reduces the trouble of using the dust cover.

[0021] (2) When installing the dust cover for the lifting table column, simply place the connecting ring on the outer surface of the lifting column and move it downwards. The connecting ring will then move into the interior of the lifting housing. Simultaneously, the inclined surface of the locking block will first contact the upper side of the lifting housing, causing the locking block to be pressed and moved into the sliding groove. The connecting spring will then be compressed. When the lower side of the dust cover top contacts the upper side of the lifting housing, the locking block will move to the connection port. The connecting spring will then reset from its compressed state, pushing the locking block back to its original position. After resetting, the locking block will move into the connection port to form a locking mechanism. Simultaneously, the locking block will push the sliding block towards the lifting outer surface. When the outer side of the shell moves, the sliding block is restricted by the connecting block and cannot fall out of the connection port. Thus, the dust cover can protect the column of the lifting table from dust. When removing the dust cover, the operator only needs to press the sliding block inside the shell. The sliding block drives the connecting block to move inside the connecting groove. The sliding block pushes the locking block to move, and the locking block will move into the sliding groove. At this time, the connecting spring begins to compress, and the locking block is released from the connection port. Then, the top of the dust cover can be moved upward to remove the entire dust cover. This method ensures that the dust cover can be locked while also allowing for quick disassembly and installation, making the use of the dust cover more convenient. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 4This utility model provides a new technical solution: a dust cover for a height-adjustable desk column, including a height-adjustable outer shell 1, a height-adjustable column 2 slidably connected inside the height-adjustable outer shell 1, the upper side of the height-adjustable column 2 extending beyond the upper side of the height-adjustable outer shell 1, and a motor 21 fixedly connected to the upper side of the height-adjustable column 2. The height-adjustable column 2 and motor 21 are existing structures and will not be explained in detail. A connecting ring 41 is provided inside the height-adjustable outer shell 1, and the connecting ring 41 is sleeved on the outer surface of the height-adjustable column 2. A dust cover top 4 is fixedly connected to the upper side of the connecting ring 41, and the dust cover top 4 is located on the upper side of the height-adjustable outer shell 1. A snap-fit ​​mechanism is provided on the height-adjustable outer shell 1 and the connecting ring 41, which enables the connecting ring 41 and the height-adjustable outer shell 1 to be tightly connected. The snap-fit ​​mechanism includes a connecting port 11, which is opened on the height-adjustable outer shell 1. On the right side of the lifting housing 1, the left wall of the connecting port 11 extends into the interior of the lifting housing 1. Connecting grooves 12 are provided on both the front and rear walls of the connecting port 11, and are located inside the lifting housing 1. A sliding block 3 is slidably connected inside the connecting port 11. Connecting blocks 31 are fixedly connected to the front and rear sides of the sliding block 3, and each of the two connecting blocks 31 extends into the interior of one of the two connecting grooves 12. A connecting port 11 is also provided on the left side of the lifting housing 1. The connecting structures of the left and right connecting ports 11 are identical and mirror-image. A sliding groove 42 is provided on the right side of the connecting ring 41, and a locking block 5 is slidably connected inside the sliding groove 42. The locking block 5 is triangular in shape with its inclined surfaces facing to the right and down. A connecting spring 5 is fixedly connected to the left side of the locking block 5. 1. The left end of the connecting spring 51 is fixedly connected to the left wall of the sliding groove 42. The snap-fit ​​block 5 is adapted to the connecting groove 12. The left side of the connecting ring 41 is also provided with a sliding groove 42. The connection structure of the left and right sliding grooves 42 is the same and they are mirror images of each other. When the dust cover is installed, the dust cover top 4 and the connecting ring 41 are respectively fitted onto the outer surface of the lifting column and connected to the inner surface of the lifting housing 1. At this time, the snap-fit ​​block 5 will extend into the interior of the connecting port 11, and the snap-fit ​​block 5 will form a snap-fit ​​state with the connecting port 11. When the lifting column 2 moves upward, the lifting column 2 moves upward and the connecting ring 41 moves upward due to friction. Because the snap-fit ​​block 5 extends into the interior of the connecting port 11, it forms a snap-fit. Therefore, the connecting ring 41 will not be moved upward by the lifting column 2 and thus will not fall off. When installing the connecting ring 41, simply place it on the outer surface of the lifting column 2 and move it downward. The connecting ring 41 will then move into the interior of the lifting housing 1. Simultaneously, the inclined surface of the locking block 5 will first contact the upper side of the lifting housing 1, and the locking block 5 will be pressed into the sliding groove 42. The connecting spring 51 will then be compressed. When the lower side of the dust cover top 4 contacts the upper side of the lifting housing 1, the locking block 5 will move to the connection port 11. The connecting spring 51 will then reset from its compressed state, pushing the locking block 5 to reset. After resetting, the locking block 5 will move into the connection port 11 to form a locking mechanism.Simultaneously, the locking block 5 pushes the sliding block 3 to move outwards from the lifting housing 1. The sliding block 3 is prevented from falling out of the connection port 11 by the connecting block 31, thus protecting the lifting table column from dust. To remove the dust cover, the operator simply presses the sliding block 3 inside the lifting housing 1. The sliding block 3 moves the connecting block 31 inside the connection groove 12, pushing the locking block 5 to move into the sliding groove 42. At this point, the connecting spring 51 is compressed, releasing the locking block 5 from the connection port 11. The top of the dust cover 4 can then be moved upwards to remove the entire dust cover. This method ensures the dust cover is tightly connected to the column, preventing it from falling off as the column rises. This eliminates the need for operators to frequently reinstall the dust cover, reducing the inconvenience of using it.

[0029] Working principle: At the start of operation, after the dust cover is installed, the top 4 of the dust cover and the connecting ring 41 are respectively fitted onto the outer surface of the lifting column and connected to the inner surface of the lifting housing 1. At this time, the locking block 5 extends into the connection port 11, thus forming a locking state with the connection port 11. When the lifting column 2 moves upward, the connecting ring 41 moves upward due to friction. Because the locking block 5 extends into the connection port 11 and forms a locking state, the connecting ring 41 will not be moved upward by the lifting column 2 and thus will not fall off. Simultaneously, when installing the connecting ring 41, simply fit it onto the outer surface of the lifting column 2 and move it downward. The connecting ring 41 will then move into the interior of the lifting housing 1. At the same time, the inclined surface of the locking block 5 will first contact the upper side of the lifting housing 1, thus the locking block 5 will be squeezed into the sliding groove 42, and the connecting spring 51 will begin to compress. When the lower side of the dust cover top 4 contacts the upper side of the lifting housing 1, the locking block 5 moves to the position of the connection port 11, and the connecting spring 51 begins to reset from the compressed state, pushing the locking block 5 to reset. After resetting, the locking block 5 moves into the inside of the connection port 11 to form a lock. At the same time, the locking block 5 pushes the sliding block 3 to move outward of the lifting housing 1. The sliding block 3 is restricted by the connecting block 31 and cannot fall out of the connection port 11. Thus, the dust cover can protect the lifting table column from dust. When removing the dust cover, the operator only needs to press the sliding block 3 inside the lifting housing 1. The sliding block 3 drives the connecting block 31 to move inside the connection groove 12. The sliding block 3 pushes the locking block 5 to move, and the locking block 5 moves into the inside of the sliding groove 42. At this time, the connecting spring 51 begins to be compressed, and the locking state between the locking block 5 and the connection port 11 is released. Then, the dust cover top 4 can be moved upward to remove the entire dust cover.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
