Description

Technical Field

[0001] This utility model belongs to the field of furniture technology, specifically relating to a pull-out table with a reverse-moving desktop. Background Technology

[0002] In existing technology, most household tables have fixed tabletops whose size cannot be changed. When the space where the table is placed or the occasion for its use changes, such as moving it from a large room to a small room, or when the number of people using the table changes, or when it is used or not used, it will cause a lot of inconvenience.

[0003] As craftsmanship and technology continue to improve, furniture manufacturers are producing new types of furniture, such as lift-up pull-out tables. Compared to traditional fixed-top tables, lift-up pull-out tables have the advantage of being able to change the size of the tabletop and make full use of space.

[0004] Chinese patent publication number "CN218791161U" discloses a vehicle-mounted pull-out and height-adjustable tea table, relating to the field of vehicle-mounted tea table technology. Specifically, it includes a tea table panel, with a fixed tabletop fixedly connected to the top of one end of the tea table panel, and a pull-out tabletop provided at the top of the other end of the tea table panel. Guide rails are fixedly connected to the top of both sides of the tea table panel, and the bottom sides of the pull-out tabletop are placed within the guide rails, allowing the pull-out tabletop to move horizontally and linearly along the guide rails. A height-adjustable table leg is vertically installed at the center of the bottom surface of the tea table panel. The height-adjustable table leg comprises multiple hollow tubes, each with a rectangular structure, and the diameter of the hollow tube gradually decreases from top to bottom. The multiple hollow tubes slide and nest with each other.

[0005] The aforementioned patent utilizes two pull-out tabletops and one fixed tabletop. When unfolded, the two pull-out tabletops are pulled outwards, creating space in the middle area. The desktop area is expanded by placing a spliced ​​tabletop in the position of the fixed tabletop. However, this method requires two additional spliced ​​tabletops to achieve the expansion, resulting in high costs and cumbersome unfolding and folding processes. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this utility model provides a pull-out table with reverse tabletop movement, which solves the technical problems of high cost of using pull-out tabletops and cumbersome unfolding and folding.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0008] A pull-out table with reverse-moving desktop includes a table frame assembly, two desktop panels, and a linkage component. The two desktop panels are symmetrically slidably connected to the table frame assembly and linked together by the linkage component. When one desktop panel is pulled out, the linkage component drives the other panel to move synchronously in the opposite direction, and the pulled-out desktop panel can rise and fall during the movement.

[0009] Furthermore, the two tabletops are divided into a lifting tabletop and a movable tabletop. The bottom of the movable tabletop is fixed with a support column, so that the movable tabletop and the support frame are spaced apart, forming a storage space. The lifting tabletop can be lowered when pushed inward and retracted into the storage space; when pulled outward, it can be raised until its top surface is flush with the top surface of the movable tabletop.

[0010] Furthermore, the lifting tabletop includes a tabletop body and a tabletop frame. Movable grooves are formed on both sides of the tabletop body. A lifting member that mates with the movable groove is fixed to the table frame assembly. The end of the lifting member extends into the movable groove, cooperating with the groove to achieve lifting and lowering when the tabletop body moves.

[0011] Furthermore, the tabletop body and the tabletop frame are connected by telescopic columns.

[0012] Furthermore, the movable groove includes an outward-extending section, a retracting section, and a lifting section. The outward-extending section and the retracting section are parallel to each other and spaced apart. The lifting section is inclined and its two ends are connected to the outward-extending section and the retracting section, respectively.

[0013] Furthermore, the linkage assembly includes a transmission rope and two pulleys. The transmission rope is wrapped around the two pulleys. The bottoms of the two tabletops are fixed to the sides of the transmission rope, respectively.

[0014] Furthermore, the transmission rope includes a first transmission part, a second transmission part, and a transition part. The first transmission part and the second transmission part are arranged in parallel, and the transition part is used to connect the ends of the first transmission part and the second transmission part. The bottom of the two desktop plates are fixed to the first transmission part and the second transmission part respectively through corresponding connectors.

[0015] Furthermore, the table frame assembly includes a support frame and table legs fixed to the bottom of the support frame. Both tabletop panels are slidably connected to the support frame.

[0016] Furthermore, track frames are fixed to both sides of the support frame. Main rails are fixed to both sides of the track frames. Sub-rails that mate with the corresponding main rails are fixed to the bottom of both desktop panels. The sub-rails slide in conjunction with the main rails.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This invention features a slidingly connected lifting tabletop and a movable tabletop on a table frame assembly. Movable grooves are provided on both sides of the lifting tabletop, and a pusher component that mates with the movable groove is fixed to the table frame assembly. Through the cooperation between the pusher component and the movable groove, the lifting tabletop can descend when pushed inward, retracting into the storage space below the movable tabletop; and rise upward when pulled outward until its top surface is flush with the top surface of the movable tabletop, thus achieving the outward extension of the pull-out tabletop. This solves the problems of high costs caused by requiring multiple tabletops for the outward extension of the pull-out tabletop, and the cumbersome technical aspects of unfolding and retracting.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1 and 2 As shown, a pull-out table with reverse-moving desktop includes a table frame assembly 1, two desktop panels 2, and a linkage assembly 3. The two desktop panels 2 are symmetrically slidably connected to the table frame assembly 1. The linkage assembly 3 is installed at the bottom of the two desktop panels 2. When one desktop panel 2 is pulled out, the linkage assembly 3 drives the other panel to complete a reverse synchronous movement, and the pulled-out desktop panel 2 can rise and fall during the movement.

[0029] The specific structure is as follows: Figure 2 As shown, the table frame assembly 1 includes a support frame 1-1 and table legs 1-2 fixed to the bottom of the support frame 1-1. Track frames 1-3 are fixed to both sides of the support frame 1-1. Main rails 1-4 are fixed to both sides of the track frames 1-3. Sub-rails 1-5, which mate with the corresponding main rails 1-4, are fixed to the bottom of each of the two tabletops 2. The sub-rails 1-5 slide with the main rails 1-4. A linkage assembly 3 is installed on the track frames 1-3, enabling the other tabletop 2 to move synchronously in the opposite direction when one tabletop 2 moves.

[0030] like Figure 3 and 4 As shown, the linkage assembly 3 includes a transmission rope 3-1 and two pulleys 3-2. The two pulleys 3-2 are rotatably connected to both ends of the track frame 1-3. The transmission rope 3-1 is connected end-to-end, with both ends wrapped around the two pulleys 3-2. The transmission rope 3-1 is divided into two parallel transmission sections 3-1-1 and 3-1-2, and a transition section connecting the two ends of the first and second transmission sections 3-1-1 and 3-1-2. The two transition sections are wrapped around the two pulleys 3-2 respectively. The secondary rails 1-5 on the two tabletops 2 are fixed to the first and second transmission sections 3-1-1 and 3-1-2 respectively via connectors 5.

[0031] In use, when the desktop panel 2 connected to the first transmission part 3-1-1 of the transmission rope 3-1 is pulled, the first transmission part 3-1-1 of the transmission rope 3-1 will move synchronously. At the same time, the second transmission part 3-1-2 of the transmission rope 3-1 will move synchronously in the opposite direction, driving the other desktop panel 2 to move in the opposite direction.

[0032] like Figure 5 As shown, the two tabletops 2 are a lifting tabletop 2-1 and a movable tabletop 2-2. The bottom of the movable tabletop 2-2 is fixed with multiple support columns 2-3, creating a storage space between the movable tabletop 2-2 and the support frame 1-1. The lifting tabletop 2-1 can be lowered when pushed inwards, retracting into the storage space; and raised when pulled outwards until its top surface is flush with the top surface of the movable tabletop 2-2.

[0033] The lifting tabletop 2-1 includes a tabletop body 2-1-1 and a tabletop frame 2-1-2. The tabletop frame 2-1-2 is fixed to the corresponding sub-rail 1-5, achieving a sliding engagement with the support frame 1-1. A telescopic column is provided between the tabletop body 2-1-1 and the tabletop frame 2-1-2, which can provide support for the tabletop body 2-1-1 while preventing interference between the tabletop body 2-1-1 and the tabletop frame 2-1-2 during lifting.

[0034] Both sides of the tabletop body 2-1-1 are provided with integrally formed lifting transmission plates 2-4. Movable slots 2-5 are formed on the lifting transmission plates 2-4. A pusher 4, which mates with the movable slots 2-5, is fixed on the support frame 1-1. The end of the pusher 4 extends into the movable slots 2-5, cooperating with them to complete the lifting operation when the tabletop body 2-1-1 moves.

[0035] The specific structure is as follows: Figure 6 As shown, the movable slot 2-5 includes an outward-extending part 2-5-1, a retracting part 2-5-2, and a lifting part 2-5-3. The outward-extending part 2-5-1 and the retracting part 2-5-2 are parallel to each other and spaced apart on the lifting transmission plate 2-4. The lifting part 2-5-3 is inclined, and its two ends are connected to the outward-extending part 2-5-1 and the retracting part 2-5-2, respectively. In the initial state, the pusher 4 is located in the retracting part 2-5-2, and the table body 2-1-1 of the lifting table 2-1 is located in the storage space below the movable table 2-2, causing the lifting table 2-1 and the movable table 2-2 to retract in a stacked manner.

[0036] When the movable table 2-2 and the lifting table 2-1 are unfolded, the worker pulls the lifting table 2-1 outward. When the top of the lifting part 2-5-3 on the lifting table 2-1 is aligned with the inner end of the pusher 4, the worker applies an upward lifting force to the table body 2-1-1 in the lifting table 2-1, allowing the inner end of the pusher 4 to smoothly enter the lifting part 2-5-3. The worker continues to pull the lifting table 2-1 outward. The table body 2-1-1 in the lifting table 2-1 rises upward with the cooperation of the pusher 4 and the lifting part 2-5-3 until it moves into the outward extension part 2-5-1. The table body 2-1-1 of the lifting table 2-1 moves upward a distance equal to the thickness of the movable table 2-2, making the table body 2-1-1 in the lifting table 2-1 flush with the movable table 2-2. The staff pushes the lifting table 2-1 inward, and in the process maintains the same lifting force as the table body 2-1-1 as the table body 2-1-1, so that the table body 2-1-1 in the lifting table 2-1 can move inward smoothly and connect with the moving table 2-2, realizing the outward splicing of the lifting table 2-1 and the moving table 2-2.

[0037] When the movable table 2-2 and the lifting table 2-1 are folded up, the worker pulls the lifting table 2-1 outwards. When the bottom end of the lifting part 2-5-3 on the lifting table 2-1 is aligned with the inner end of the pushing member 4, the table body 2-1-1 in the lifting table 2-1 moves downwards under gravity, allowing the inner end of the pushing member 4 to enter the lifting part 2-5-3. After the inner end of the pushing member 4 has entered the lifting part 2-5-3, the worker pushes the lifting table 2-1 inwards. The table body 2-1-1 in the lifting table 2-1 continues to move downwards with the cooperation of the pushing member 4 and the lifting part 2-5-3 until it moves downwards a distance equal to the thickness of the movable table 2-2. This allows the table body 2-1-1 in the lifting table 2-1 to smoothly enter the storage space below the movable table 2-2, achieving the stacked storage of the lifting table 2-1 and the movable table 2-2.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
