[0002] As the most common type of furniture, tables have been accompanying people's daily lives for thousands of years. At the same time, in order to cater to public demand, the types of tables are also constantly evolving. The existing tables on the market can be divided into many categories according to demand, such as office desks, dining tables, desks for classes, computer desks for placing computers, and desks for studying and reading, etc.

[0003] Similarly, according to their structures, they can be divided into height-adjustable lifting tables and foldable tables that can be folded and stored, etc.; since the expansion table includes both expansion and storage forms, it can be applied to more usage scenarios and is favored by more and more families; as a type of expansion table, the pull-out table realizes the switching between the expansion and storage forms by pulling out, but the pull-out tables in the prior art mostly adopt a semi-automatic / fully-automatic pull-out table consisting of two side table tops, a middle table top and a guide rail, or a manual pull-out table consisting of two table tops and a guide rail. To complete the expansion or folding of the table top, basically two to three steps are required and human assistance is required to complete; therefore, a pull-out table is needed to solve the problems of the prior art pull-out tables being bloated in structure, inconvenient to deform and operate, and requiring collaboration of multiple people. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a sliding retractable pull-out table to solve the problems of the pull-out table in the prior art, such as bloated structure, inconvenient deformation operation and need for cooperation of multiple people.

[0005] In order to solve the above technical problems, the utility model provides a sliding retractable pull-out table, comprising:

[0006] A support frame, the support frame comprising a front bracket and a rear bracket, the front bracket being slidably disposed on the rear bracket, and the front bracket being pulled to reduce or increase the distance between the front bracket and the rear bracket, so that the support frame is switched between an extended position and a stored position;

[0007] A telescopic table top, the telescopic table top comprising a plurality of table top rods arranged in parallel on the front bracket and the rear bracket and a plurality of telescopic stoppers connecting two adjacent table top rods, the plurality of table top rods are assembled together to form a complete table top, the telescopic stoppers satisfy that two adjacent table top rods abut against each other or are spaced apart from each other at a certain distance, and the table top rods at the front end and the rear end are fixed to the front bracket and the rear bracket respectively;

[0008] Pull the front bracket toward the front side to increase the distance between the front bracket and the rear bracket, so that the support frame is in the expanded position, and use the telescopic limiter to make the adjacent table top rods spaced at a certain distance from each other, and the sliding telescopic pull-out table is in the expanded state; push the front bracket toward the rear side to reduce the distance between the front bracket and the rear bracket, so that the support frame is in the stored position, the adjacent table top rods abut against each other, and the sliding telescopic pull-out table is in the stored state.

[0009] As a more preferred embodiment, the rear bracket includes a rear beam and two rear side rods connected to both ends of the rear beam and perpendicular to each other. The two rear side rods are horizontally arranged and provided with slide grooves, and the front bracket can be slidably mounted on the slide grooves.

[0010] As a more preferred embodiment, the front bracket includes a front beam and two front side sliding bars connected to and perpendicular to the two ends of the front beam.

[0011] As a more preferred embodiment, the front bracket also includes a front reinforcing beam whose two ends are respectively connected to the two front side sliding rods. The front reinforcing beam further ensures the structural strength of the front bracket, improves the stability when sliding on the rear bracket, and improves the service life of the sliding retractable pull-out table of the utility model.

[0012] As a more preferred manner, the tops of the rear rod and the front sliding rod are flush with each other, a plurality of the table top rods are overlapped on the tops of the rear rod and the front sliding rod, and the table top rod is perpendicular to the rear rod and the front sliding rod. This ensures that the table top of the retractable pull-out table is flat. At the same time, when the sliding retractable pull-out table switches between the storage state and the unfolded state, the table top rod slides more smoothly on the tops of the rear rod and the front sliding rod.

[0013] As a more preferred embodiment, a limiting long hole is provided on the telescopic limiting member, and a limiting pin adapted to the limiting long hole is provided on the table top rod. One end of the telescopic limiting member is fixed on one of the two adjacent table top rods, and the limiting long hole of the telescopic limiting member is sleeved on the limiting pin of the other table top rod.

[0019] As described above, the sliding retractable pull-out table of the utility model has the following beneficial effects: when the sliding retractable pull-out table of the utility model is in use, in a scenario where a small number of people use the table in daily life at home, the front bracket is pulled forward to increase the distance between the front bracket and the rear bracket, so that the support frame is in the unfolded position, and the telescopic limiter is used to make the adjacent table top rods spaced apart from each other at a certain distance, so that the sliding retractable pull-out table is in the storage state, which reduces the placement space and also meets the needs of a small number of people using the table at the same time;

[0020] In a scenario where multiple people use the table, such as a dinner party, the front bracket is pushed toward the rear side to reduce the distance between the front bracket and the rear bracket, so that the support frame is in the storage position, and the telescopic limiter is used to make the adjacent table top rods abut against each other, so that the sliding telescopic pull-out table is in the unfolded state, at this time, the table space is expanded, and the needs of multiple people using the table at the same time are met;

[0021] To sum up, the sliding retractable pull-out table of the utility model realizes the switching between the storage state and the unfolded state through the retractable and sliding support frame and the retractable table top with variable intervals.

[0048] like Figures 1 to 5 As shown, the utility model provides a sliding retractable pull-out table, comprising:

[0049] A support frame 1, wherein the support frame 1 comprises a front support 12 and a rear support 11, wherein the front support 12 is slidably disposed on the rear support 11, and the front support 12 is pulled to reduce or increase the distance between the front support 12 and the rear support 11, so that the support frame 1 is switched between an unfolded position and a stowed position;

[0050] The telescopic table top 2 includes a plurality of table top rods 21 arranged in parallel on the front bracket 12 and the rear bracket 11, and a plurality of telescopic stoppers 22 connecting two adjacent table top rods 21. The plurality of table top rods 21 are assembled together to form a complete table top. The telescopic stoppers 22 ensure that two adjacent table top rods 21 abut against each other or are spaced apart from each other at a certain distance. The table top rods 21 at the front end and the rear end are fixed to the front bracket 12 and the rear bracket 11 respectively.

[0051] Pull the front bracket 12 toward the front side to increase the distance between the front bracket 12 and the rear bracket 11, so that the support frame 1 is in the expanded position, and use the telescopic limiter 22 to make the adjacent table top rods 21 spaced apart from each other at a certain distance, and the sliding telescopic pull-out table is in the expanded state; push the front bracket 12 toward the rear side to reduce the distance between the front bracket 12 and the rear bracket 11, so that the support frame 1 is in the stored position, and use the telescopic limiter 22 to make the adjacent table top rods 21 abut against each other, and the sliding telescopic pull-out table is in the stored state.

[0052] When the sliding retractable pull-out table of the utility model is in use, in a scenario where a small number of people use it in daily life at home, the front bracket 12 is pulled forward to increase the distance between the front bracket 12 and the rear bracket 11, so that the support frame 1 is in the expanded position, and the telescopic limiter 22 is used to make the adjacent table top rods 21 spaced apart from each other at a certain distance, so that the sliding retractable pull-out table is in the storage state, which reduces the placement space and also meets the needs of a small number of people using it at the same time, such as Figure 1 as well as Figure 2 As shown;

[0053] In a scenario where multiple people use the table, such as a dinner party, the front bracket 12 is pushed toward the rear side to reduce the distance between the front bracket 12 and the rear bracket 11, so that the support frame 1 is in the storage position, and the telescopic limiter 22 is used to make the adjacent table top rods 21 abut against each other, so that the sliding telescopic pull-out table is in the unfolded state, at this time, the table space is expanded, and the needs of multiple people using the table at the same time are met. Figure 4 as well as Figure 5 As shown;

[0054] In this embodiment, if Figure 1As shown, the rear support 11 includes a rear beam 111 and two rear side rods 112 connected to both ends of the rear beam 111 and perpendicular to each other. The two rear side rods 112 are arranged horizontally and a slide groove 112 a is arranged on the rear side rods 112 .

[0055] In this embodiment, if Figure 1 As shown, the front bracket 12 includes a front beam 121 and two front side slide bars 122 connected to both ends of the front beam 121 and perpendicular to the front beam 121. The two front side slide bars 122 are horizontally arranged and respectively slidably arranged on the slide grooves 112a corresponding to the rear side bars 112. The two front side slide bars 122 can satisfy the requirement that the front bracket 12 slides more smoothly on the rear bracket 11.

[0056] In this embodiment, if Figure 1 As shown, the front bracket 12 also includes a front reinforcing beam 123 whose two ends are respectively connected to the two front side sliding rods 122, and the front reinforcing beam 123 further ensures the structural strength of the front bracket 12, improves the stability when sliding on the rear bracket 11, and improves the service life of the sliding retractable pull-out table of the utility model; further, in this embodiment, a total of two front reinforcing beams 123 are arranged on the front bracket 12, and the two ends of the two front reinforcing beams 123 are respectively connected to the two front side sliding rods 122, and maintain a certain interval.

[0057] In this embodiment, if Figure 1 As shown, the tops of the rear rod 112 and the front sliding rod 122 are flush with each other, and a plurality of the table top rods 21 are overlapped on the tops of the rear rod 112 and the front sliding rod 122, and the table top rod 21 is perpendicular to the rear rod 112 and the front sliding rod 122. This ensures that the table top of the retractable pull-out table is flat. At the same time, when the sliding retractable pull-out table switches between the storage state and the unfolded state, the table top rod 21 slides more smoothly on the tops of the rear rod 112 and the front sliding rod 122.

[0058] In this embodiment, if Figure 3 As shown, a limiting long hole 221 is provided on the telescopic limiting member 22, and a limiting pin 211 adapted to the limiting long hole 221 is provided on the table top rod 21. One end of the telescopic limiting member 22 is fixed to one of the two adjacent table top rods 21, and the limiting long hole 221 of the telescopic limiting member 22 is sleeved on the limiting pin 211 of the other table top rod 21. The limiting pin 211 of the other table top rod 21 moves back and forth along the limiting long hole 221, so that the two adjacent table top rods 21 abut against each other or are spaced apart from each other at a certain distance.

[0059] In this embodiment, if Figure 1 as well as Figure 3As shown, the telescopic limit members 22 are divided into two rows along the front-to-back direction, wherein the telescopic limit members 22 spaced apart from each other are arranged in a row, so as to avoid interference between adjacent telescopic limit members 22 when the sliding telescopic pull-out table is in the storage state, resulting in the inability of adjacent table top rods 21 to abut against each other, thereby affecting the user experience; further, in the present embodiment, in order to control the maximum interval between adjacent table top rods 21 and to ensure the structural strength, the length of the telescopic limit member 22 is twice the width of the table top rod 21, but the telescopic limit member 22 and the table top rod 21 are in a one-to-one correspondence. If the telescopic limit members 22 are arranged in a row, when the adjacent telescopic pull-out table is in the storage state, When the retractable limit members 22 abut against each other in pairs, the adjacent table top rods 21 cannot abut against each other. In this way, in order to meet the requirement that the adjacent table top rods 21 abut against each other when the sliding retractable pull-out table is in the storage state, the two adjacent table top rods 21 that abut against each other correspond to one retractable limit member 22, and the retractable limit member 22 is divided into two rows and interleaved. Similarly, the length of the retractable limit member 22 can also be set to three times the width of the table top rod 21, and the corresponding retractable limit member 22 needs to be divided into three rows and interleaved. At this time, the long diameter of the limiting long hole 221 can be longer, and the maximum interval between adjacent table top rods 21 can also be larger.

[0060] In this embodiment, two adjacent table top rods 21 are connected by two or more telescopic limit members 22 arranged side by side. The multiple telescopic limit members 22 arranged side by side can ensure that the relative movement between adjacent table top rods 21 is smoother, and also ensure that when one of the telescopic limit members 22 fails, the other telescopic limit member 22 can ensure that the sliding telescopic pull-out table can continue to work.

[0061] Furthermore, in this embodiment, the telescopic limiter 22 can be made of plastic material and can be rapidly mass-produced using an injection molding process.

[0062] In this embodiment, if Figure 1 as well as Figure 3 As shown, the pull-out telescopic folding table also includes legs 3. Further, in the present embodiment, the legs 3 include four in total, two of which are arranged on the front bracket 12 and are respectively fixed to the two ends of the front beam 121, and the other two are arranged on the rear bracket 11 and are respectively fixed to the two ends of the rear beam 111. In this way, the pull-out telescopic folding table is more stable when placed. Further, in the present embodiment, anti-slip pads 31 are also provided at the bottom of the legs 3 to reduce relative sliding with the ground and further improve the stability of placement.

[0063] In this embodiment, a positioning block is further provided on the support frame 1, and the positioning block is used to limit the support frame 1 when it moves to the unfolded position and the stored position.

[0064] Furthermore, in the present embodiment, the support frame 1 also includes a locking structure. When the pull-out retractable folding table is switched to an unfolded state or a stowed state, the support frame 1 is locked to prevent relative sliding between the front bracket 12 and the rear bracket 11.

[0065] In summary, the sliding retractable pull-out table of the utility model realizes the switching between the two states of storage and unfolding through the retractable and sliding support frame 1 and the retractable table board 2 with variable intervals. At the same time, the structure is simple and the state switching is convenient, which can be completed by one person, thus solving the problems of the pull-out table in the prior art, such as bloated structure, inconvenient deformation operation and the need for cooperation of multiple people. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0066] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
