DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0041] Embodiment 1:

[0042] A stretchable tabletop for a cabinet comprises a cabinet 1, a panel 2 and a tabletop 3, wherein the panel 2 is fixedly connected to the top of the cabinet 1, the tabletop 3 is slidably connected to the inside of the panel 2, and limiting mechanisms are provided on both sides of the cabinet 1, which can limit the panel 2 after its position is adjusted;

[0043] A supporting mechanism, which is fixedly arranged on both sides of the cabinet 1 and can be supported by the supporting mechanism after the stretchable table top 3 is stretched;

[0044] One implementation method of the present embodiment 1 is: the limiting mechanism includes a shell 4 fixedly connected to one side of the panel 2, the inner wall of the shell 4 is fixedly connected to a spring 5, one side of the spring 5 is fixedly connected to a moving block 6, one side of the moving block 6 is fixedly connected to a limiting rod 7, and both sides of the table top 3 are provided with a plurality of limiting holes 8 used in conjunction with the limiting rod 7.

[0045] The embodiment takes into account that when the user does not need such a large cooking operation space, the fully stretched table top 3 will occupy a large kitchen space, which is not conducive to the user's use. Therefore, by providing a limiting mechanism, the table top 3 can be pulled outward by applying a certain force, so that after the table top 3 is moved to an appropriate position, the elastic force generated by the spring 5 will push the moving block 6 and the limiting rod 7 to move, so that the limiting rod 7 enters the corresponding limiting hole 8 to complete the limiting of the table top 3. The number of limiting holes 8 is several, and the table top 3 can be stretched to any position for limiting, so as to avoid the table top 3 being stretched too long and occupying too much space, which affects the use of the user;

[0046] The problem is that when the user does not need such a large cooking space, the fully extended tabletop 3 will occupy a large kitchen space, which is not conducive to the user's use;

[0047] It should be noted that one end of the limiting rod 7 is spherical. When a certain force is applied to pull the table top 3 to move, it is squeezed by the inner wall of the limiting hole 8 and moves with the moving block 6 to the side close to the spring 5, squeezing the spring 5 at the same time.

[0048] Preferably, a stabilizing block 25 is fixedly connected to one side of the desktop 3, and two mounting grooves 26 are provided on the top and bottom of the stabilizing block 25. The inner wall of the mounting groove 26 is rotatably connected to a plurality of guide wheels 27, and the inner wall of the panel 2 is provided with a guide groove 28 used in conjunction with the guide wheel 27.

[0049] This embodiment provides a stabilizing block 25, a placement groove 26, a guide wheel 27 and a guide groove 28, so that the stability of the desktop 3 after stretching can be improved through the stabilizing block 25. At the same time, the design of the guide wheel 27 and the guide groove 28 can improve the stability of the desktop 3 during the stretching and moving process.

[0050] Preferably, one end of the limiting rod 7 is spherical.

[0051] In this embodiment, by setting one end of the limiting rod 7 to be spherical, when a certain force is applied to pull the table top 3 to move, it can be squeezed by the inner wall of the limiting hole 8 and move with the moving block 6 to the side close to the spring 5, thereby playing a transmission role.

[0052] Embodiment 2:

[0053] On the basis of Example 1, the limiting mechanism in this embodiment can enable the desktop 3 to reasonably adjust the stretching distance. However, considering that after the desktop 3 is stretched out, it is easy for the user to shake it while cooking due to the lack of support, causing the items placed on the desktop 3 to fall off. The supporting mechanism in this application includes a first sleeve 9 movably arranged on both sides of the cabinet 1, a lifting block 10 is arranged inside the first sleeve 9, the top of the lifting block 10 is fixedly connected to a supporting block 11, a rotating block 12 is arranged at the bottom of the first sleeve 9, the top of the rotating block 12 is fixedly connected to a first threaded rod 13, and a first threaded hole 14 for use with the first threaded rod 13 is opened at the bottom of the lifting block 10.

[0054] In this embodiment, it is considered that after the table top 3 is stretched out, due to the lack of support, the user is prone to shaking when cooking, causing the items placed on the table top 3 to fall off. Therefore, a support mechanism is provided to enable the table top 3 to be stretched out. Figure 3 and Figure 5 As shown, by rotating the rotating block 12, the rotating block 12 drives the first threaded rod 13 to rotate. When the first threaded rod 13 rotates, the external thread on its surface squeezes the internal thread of the threaded hole, so that the lifting block 10 moves upward along the track of the sliding block 22 and the sliding groove 23. The lifting block 10 drives the supporting block 11 to move upward, and then the top of the supporting block 11 contacts the bottom of the desktop 3, thereby supporting the desktop 3 and improving the stability of the desktop 3.

[0055] The problem that the table top 3 is easily shaken when a user cooks due to lack of support after being stretched out is solved, resulting in the falling of items placed on the table top 3.

[0056] Preferably, sliding blocks 22 are fixedly connected to both sides of the lifting block 10 , and a sliding groove 23 for use with the sliding block 22 is formed on the inner wall of the first sleeve 9 .

[0057] In this embodiment, by setting the sliding block 22 and the sliding groove 23, when the first threaded rod 13 rotates, the external thread on its surface will squeeze the internal thread of the threaded hole, so that the lifting block 10 can only move along the trajectory of the sliding block 22 and the sliding groove 23, thereby limiting the movement trajectory.

[0058] Preferably, a bearing 24 is sleeved on the surface of the first threaded rod 13 , and the top of the rotating block 12 is rotatably connected to the bottom of the first sleeve 9 through the bearing 24 .

[0059] In this embodiment, by providing the bearing 24, the position of the first threaded rod 13 can be limited, and at the same time, the first threaded rod 13 can be restricted to rotate only around the bearing 24, thereby improving the smoothness of the rotation process.

[0060] Embodiment three:

[0061] On the basis of the first embodiment, the support mechanism in this embodiment can support the stretched desktop 3, but considering that the stretched length of the desktop 3 can be adjusted, if the position supported by the support mechanism cannot be adjusted, the stability of the support will also be affected. In this application, adjustment mechanisms are provided on both sides of the cabinet 1, which can adjust the position supported by the support mechanism;

[0062] The adjustment mechanism includes a second sleeve 15 fixedly connected to both sides of the cabinet 1, an adjustment rod 16 is arranged inside the second sleeve 15, one end of the adjustment rod 16 passes through one side of the first sleeve 9 and is fixedly connected to one side of the first sleeve 9, the top of the second sleeve 15 is threadedly connected to a second threaded rod 17, the top of the second sleeve 15 is provided with a second threaded hole 18 used in conjunction with the second threaded rod 17, the top of the second threaded rod 17 is fixedly connected to a twisting block 19, and the bottom of the second threaded rod 17 is fixedly connected to a clamping block 20.

[0063] In this embodiment, the stretched length of the desktop 3 is adjustable. If the position of the support mechanism cannot be adjusted, the stability of the support will be affected. Therefore, an adjustment mechanism is provided, such as Figure 3 As shown, the second threaded rod 17 can be driven to rotate in the second threaded hole 18 by rotating the twisting block 19. At this time, the second threaded rod 17 will move upward, and the second threaded rod 17 will drive the clamping block 20 and the anti-sliding block 21 to move upward, thereby releasing the restriction on the adjustment rod 16. At this time, the first sleeve 9 can be pulled to drive the adjustment rod 16 to move, thereby adjusting the position of the support mechanism. After reaching the appropriate position, the twisting block 19 is rotated in the opposite direction to drive the second threaded rod 17 to rotate. The second threaded rod 17 will drive the clamping block 20 and the anti-sliding block 21 to move downward, tightly contacting the surface of the adjustment rod 16, and limiting the adjustment rod 16 through pressure, thereby achieving the effect of adjusting the support position of the support mechanism, thereby further improving the stability of the desktop 3.

[0064] Preferably, an anti-sliding block 21 is fixedly connected to the bottom of the pressing block 20 , and the anti-sliding block 21 is made of rubber.

[0065] In this embodiment, the anti-sliding block 21 is provided to increase the friction force after the pressing block 20 contacts the adjusting rod 16 , thereby improving the stability of the adjusting rod 16 .

[0066] Working principle: the user applies a certain force to pull the desktop 3 outwards, and after the desktop 3 moves to an appropriate position, the elastic force generated by the spring 5 will push the moving block 6 and the limiting rod 7 to move, so that the limiting rod 7 enters the corresponding limiting hole 8 to complete the limiting of the desktop 3. The number of limiting holes 8 is several, and the desktop 3 can be limited to any position when stretched to avoid the desktop 3 being stretched too long and occupying too much space, which affects the use of users;

[0067] At the same time, after the desktop 3 is stretched out, the rotating block 12 is rotated, and the rotating block 12 drives the first threaded rod 13 to rotate. When the first threaded rod 13 rotates, the external thread on its surface squeezes the internal thread of the threaded hole, so that the lifting block 10 moves upward along the trajectory of the sliding block 22 and the sliding groove 23, and the lifting block 10 drives the supporting block 11 to move upward, and then the top of the supporting block 11 contacts the bottom of the desktop 3, thereby supporting the desktop 3 and improving the stability of the desktop 3.

[0068] Taking into account that the stretched length of the desktop 3 is adjustable, if the position of the support mechanism cannot be adjusted, the stability of the support will also be affected. Therefore, by setting an adjustment mechanism, the second threaded rod 17 can be driven to rotate in the second threaded hole 18 by rotating the twisting block 19. At this time, the second threaded rod 17 will move upward, and the second threaded rod 17 will drive the clamping block 20 and the anti-sliding block 21 to move upward, releasing the restriction on the adjustment rod 16. At this time, the first sleeve 9 can be pulled to drive the adjustment rod 16 to move, thereby adjusting the position of the support mechanism. After reaching the appropriate position, the twisting block 19 is rotated in the opposite direction to drive the second threaded rod 17 to rotate. The second threaded rod 17 will drive the clamping block 20 and the anti-sliding block 21 to move downward, tightly contacting the surface of the adjustment rod 16, and limiting the adjustment rod 16 through pressure, thereby achieving the effect of adjusting the support position of the support mechanism, and further improving the stability of the desktop 3.

[0069] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
