Description

Technical Field

[0001] This utility model relates to the technical field of tables, and in particular to a stretchable and unfoldable table. Background Technology

[0002] A table is a piece of furniture, typically with a flat tabletop and supporting legs, used for placing items, working, or dining. Its core function is to provide a stable surface to support items such as books, computers, and tableware. It can also serve as a platform for working, studying, writing, or drawing, and can be used for family gatherings, meetings, or social events.

[0003] Currently, tabletops are generally fixed, with a constant usable area, which is inconvenient to use and takes up a large area, making them difficult to transport and store. Therefore, this utility model proposes a stretchable table that differs from existing technologies to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the issue of a constant usable area on the desktop mentioned above, this invention provides a stretchable and expandable table.

[0005] This utility model provides a retractable table, which adopts the following technical solution:

[0006] A retractable table includes a second desktop panel. Support components are installed at the four corners of the lower surface of the second desktop panel. Support legs are provided at the bottom of the multiple sets of support components. Multiple sets of sliding components are installed on both side walls of the second desktop panel. A first desktop panel is installed on the upper surface of the multiple sets of sliding components. Multiple sets of positioning holes are evenly opened on the lower surface of the two sets of first desktop panels. Threaded plug-in components are installed on both end faces of the second desktop panel.

[0007] By adopting the above technical solution, the items to be placed are placed on the work panel formed by the splicing of two sets of first desktop panels to meet the usage requirements. The support components and support leg components can stably support the first desktop panels and the second desktop panels. By screwing the threaded plug-in components and using the sliding components to pull the first desktop panels outward to the appropriate position, the two sets of first desktop panels can be fully unfolded.

[0008] Optionally, the sliding assembly includes a slide rail, which is fixedly welded to the outer wall of the second desktop panel, and a slider welded to the lower surface of the first desktop panel is slidably sleeved in the inner cavity of the slide rail.

[0009] Optionally, the threaded insertion assembly includes an internally threaded tube, which is fixedly welded to the outer wall of the second desktop plate. An externally threaded tube is inserted through the internally threaded tube and is matched with the positioning insertion hole. A rotating rod plate is fixedly welded to the bottom end of the externally threaded tube.

[0010] By adopting the above technical solution, the screwing of multiple sets of rotating discs drives the external threaded tube to rotate synchronously and separate it from the positioning hole at the corresponding position. Then, the first desktop plate is pulled outward so that it slides synchronously to the appropriate position in the inner cavity of the slide through the slider. This reduces the overlap between the first desktop plate and the second desktop plate, allowing the two sets of first desktop plates to be fully unfolded. This enables the first desktop plate to cooperate with the second desktop plate for use, which is convenient for meeting the needs of customers.

[0011] Optionally, the support assembly includes a first diagonal brace, and multiple sets of the first diagonal braces are provided. The multiple sets of the first diagonal braces are obliquely welded to the lower surface of the second desktop board. A vertical connecting pipe is fixedly welded to the bottom end of the multiple sets of the first diagonal braces. A vertical support plate that penetrates the vertical connecting pipe is movably sleeved inside the vertical connecting pipe. Multiple sets of circular insertion holes are evenly opened on the outer wall of the vertical support plate. A plug rod that penetrates the vertical connecting pipe and is inserted into and matched with the circular insertion holes is provided on one side of the outer wall of the vertical connecting pipe. Multiple sets of springs that are connected to the outer wall of the vertical connecting pipe are installed on the plug rod.

[0012] Optionally, the support assembly includes a base tube, which is movably sleeved on the bottom wall of the vertical support plate. A base plate is fixedly welded to the lower surface of the base tube. Multiple sets of second diagonal braces are obliquely welded to the outer walls of the base tube, and the bottom ends of the multiple sets of second diagonal braces are welded to each other at the upper surface of the base plate.

[0013] By adopting the above technical solution, multiple sets of base tubes are respectively fitted onto the bottom ends of multiple sets of vertical support plates. The area of ​​the lower surface of the vertical support plate can be increased by using multiple sets of second diagonal braces, base tubes and base plates. Pulling the plug outward separates it from the circular plug hole. Then, the second tabletop moves up and down, causing multiple sets of first diagonal braces to move synchronously to an appropriate height. Then, the plug is released, and under the elastic force of the spring, the plug automatically re-engages with the circular plug hole at the corresponding height. Thus, the overall height of the extendable table can be easily and flexibly adjusted as needed.

[0014] Optionally, a storage frame is fixedly welded to the lower end of the outer wall of multiple sets of the first diagonal bracing rods. Multiple sets of connecting rods that are connected to the outer wall of the vertical connecting pipe are obliquely welded to the bottom of the outer wall of the storage frame. Multiple sets of pads are uniformly welded to the inner walls on both sides of the storage frame, and storage boards are provided on the multiple sets of pads.

[0015] By adopting the above technical solution, the shelf is placed on the pad, and then the items to be placed are stacked on the upper surface of the shelf and the lower surface of the inner cavity of the shelf frame at the corresponding positions, which facilitates the storage of items.

[0016] In summary, this utility model has at least one of the following beneficial effects:

[0017] Twisting multiple sets of rotating discs drives the external threaded tube to rotate synchronously and separate it from the positioning hole at the corresponding position. Then, pull the first desktop plate outward and slide it to the appropriate position. Then, simply twist the rotating discs in the opposite direction to drive the external threaded tube to fully re-engage with the positioning hole at the corresponding position. This allows the two sets of first desktop plates to be fully unfolded, so that the first desktop plate can cooperate with the second desktop plate to form a complete unit for use, which can meet the needs of customers.

[0018] Place the items to be placed on the upper surface of the shelf in the corresponding position and on the lower surface of the inner cavity of the shelf for easy storage. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0025] Please refer to the attached diagram in the instruction manual. Figure 1 , 23. One embodiment of this utility model: a stretchable table, including a second tabletop 18, with support components installed at the four corners of the lower surface of the second tabletop 18. The support components include first diagonal braces 3, and multiple sets of first diagonal braces 3 are provided. The multiple sets of first diagonal braces 3 are obliquely welded to the lower surface of the second tabletop 18. The bottom ends of the multiple sets of first diagonal braces 3 are fixedly welded to vertical connecting pipes 12. A vertical support plate 11 is movably sleeved inside the vertical connecting pipe 12 and passes through the vertical connecting pipe 12. The lateral longitudinal section of the vertical support plate 11 is T-shaped. Multiple sets of circular insertion holes 5 are evenly opened on the outer wall of the vertical support plate 11. An insertion rod 4 is provided on one side of the outer wall of the vertical connecting pipe 12, which passes through the vertical connecting pipe 12 and is inserted into and matched with the circular insertion holes 5.

[0026] Please refer to the attached diagram in the instruction manual. Figure 1 , 2 Multiple sets of springs 13 connected to the outer wall of the vertical connecting pipe 12 are installed on the insertion rod 4. Each set of vertical support plates 11 has a support foot assembly at its bottom. The support foot assembly includes a base tube 7, which is movably sleeved on the bottom wall of the vertical support plate 11. A base plate 10 is fixedly welded to the lower surface of the base tube 7. Multiple sets of second diagonal braces 6 are obliquely welded to the outer wall of the base tube 7. The bottom ends of the multiple sets of second diagonal braces 6 are welded to the upper surface of the base plate 10. The cross-sectional dimension of the base plate 10 is larger than that of the base tube 7.

[0027] Multiple sets of base tubes 7 are respectively fitted onto the bottom ends of multiple sets of vertical support plates 11. The area of ​​the lower surface of the vertical support plate 11 can be increased by using multiple sets of second diagonal braces 6, base tubes 7 and base plates 10. Items to be placed are placed on the work panel formed by the splicing of two sets of first desktop panels 14 to meet the needs of use. Moving the second desktop panel 18 up and down drives multiple sets of first diagonal braces 3 and vertical connecting tubes 12 to slide synchronously to an appropriate height. Then, the insertion rod 4 is released. Under the elastic force of the spring 13, the insertion rod 4 is automatically driven to re-engage with the circular insertion hole 5 at the corresponding height. Thus, the overall height of the stretchable table can be flexibly adjusted as needed.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 Multiple sets of sliding components are installed on both sides of the second desktop panel 18. The sliding components include slide rails 19. The slide rails 19 are fixedly welded to the outer wall of the second desktop panel 18. The inner cavity of the slide rails 19 is fitted with sliders 17. The upper surfaces of the multiple sets of sliders 17 are fitted with first desktop panels 14. Multiple sets of positioning holes 21 are evenly opened on the lower surfaces of the two sets of first desktop panels 14.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1 and 2Both ends of the second desktop panel 18 are equipped with threaded plug-in assemblies. The threaded plug-in assembly includes an internal threaded tube 1, which is fixedly welded to the outer wall of the second desktop panel 18. An external threaded tube 20 is inserted through the internal thread of the internal threaded tube 1 and is matched with the positioning plug hole 21. A rotating rod disk 2 is fixedly welded to the bottom end of the external threaded tube 20.

[0030] Pull the first desktop plate 14 outward so that it slides synchronously to the appropriate position in the inner cavity of the slide rail 19 via the slider 17. Rotate the rotating rod 2 in the opposite direction to drive the external threaded tube 20 to fully re-engage with the positioning hole 21 at the corresponding position. This can reduce the overlap between the first desktop plate 14 and the second desktop plate 18, allowing the two sets of first desktop plates 14 to fully unfold.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 , 2 4. A storage frame 8 is fixedly welded to the lower end of the outer wall of the multiple sets of first diagonal bracing rods 3. The front side of the storage frame 8 is set to be open, and the upper side of the storage frame 8 is also set to be open. Multiple sets of connecting rods 9 that are connected to the outer wall of the vertical connecting pipe 12 are welded at an angle to the bottom of the outer wall of the storage frame 8. Multiple sets of pads 15 are evenly welded to the inner walls on both sides of the storage frame 8. Storage boards 16 are set on the multiple sets of pads 15.

[0032] Place the shelf 16 on the pad 15, and then place the items to be placed on the upper surface of the shelf 16 and the lower surface of the inner cavity of the shelf frame 8 in the corresponding positions for easy storage.

[0033] Working principle: When using this extendable table, multiple sets of base tubes 7 are respectively fitted onto the bottom of multiple sets of vertical support plates 11. The area of ​​the lower surface of the vertical support plate 11 can be increased by using multiple sets of second diagonal braces 6, base tubes 7 and base plates 10, thereby reducing pressure and improving the support stability of the extendable table. Then, the items to be placed are simply placed on the work panel formed by the two sets of first desktop panels 14 to meet the usage requirements.

[0034] Pulling the plug rod 4 outward causes the spring 13 to extend and deform elastically, separating it from the circular insertion hole 5. Then, moving the second desktop plate 18 up and down causes multiple sets of first diagonal braces 3 to move synchronously, allowing the first diagonal braces 3 to drive the vertical connecting pipe 12 to slide synchronously on the outer wall of the vertical support plate 11 to an appropriate height. Then, releasing the plug rod 4 causes it to automatically re-engage with the circular insertion hole 5 at the corresponding height under the elastic force of the spring 13, thus allowing the overall height of the extendable table to be flexibly adjusted as needed.

[0035] Twisting the multi-set rotating disc 2 drives the external threaded tube 20 to rotate synchronously. Under the action of the internal threaded tube 1, the external threaded tube 20 can be separated from the positioning socket 21 at the corresponding position during rotation. Then, the first desktop plate 14 is pulled outward so that it slides synchronously to the appropriate position in the inner cavity of the slide rail 19 through the slider 17. Then, simply twisting the rotating disc 2 in the opposite direction drives the external threaded tube 20 to fully re-engage with the positioning socket 21 at the corresponding position. This reduces the overlap between the first desktop plate 14 and the second desktop plate 18, allowing the two sets of first desktop plates 14 to fully unfold. This allows the first desktop plate 14 to cooperate with the second desktop plate 18 for use, which is convenient for meeting the customer's needs.

[0036] Place the shelf 16 on the pad 15, and then place the items to be placed on the upper surface of the shelf 16 and the lower surface of the inner cavity of the shelf frame 8 in the corresponding positions for easy storage.
