Description

Technical Field

[0001] The present application relates to the field of furniture, and in particular to a slide rail structure and a dining table. Background Art

[0002] Currently, the dining table is mainly a fixed tabletop. In order to adapt the dining table to more usage scenarios, a dining table has been developed, which includes a main tabletop and a secondary tabletop, and the secondary tabletop is slidably connected to the main tabletop through a slide rail. The relative position of the main tabletop and the secondary tabletop can be adjusted according to actual needs, thereby adjusting the size of the dining table to adapt to more usage scenarios. However, the general slide rail has poor stability. When the secondary tabletop slides relative to the main tabletop to the unfolded state of the dining table, the stability of the secondary tabletop of the dining table is not guaranteed.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there is a defect that the existing slide rails have poor stability. Summary of the invention

[0004] In order to keep the slide rail stably in the unfolded state,

[0005] In the first aspect, the present application provides a slide rail structure, which adopts the following technical solution:

[0006] The camming mechanism is a kind of sliding mechanism, and its first and second ends are used for the sliding of the camming mechanism, and its second ends are used for the sliding of the camming mechanism.

[0007] By adopting the above technical solution, when the slide rail is in a retracted state, the auxiliary slide rail is located inside the main slide rail and maintains a stable posture. When the slide rail needs to be converted to an expanded state, first slide the auxiliary slide rail relative to the main slide rail until the auxiliary slide rail slides to the expanded state. Then rotate the auxiliary slide rail relative to the first connecting block so that the card block is inserted into the card slot. The card slot limits the card block, so that the auxiliary slide rail is stably fixed relative to the main slide rail, so that the slide rail is stably maintained in the expanded state. The overall stability of the slide rail is improved. At the same time, when the slide rail is in a retracted state, the auxiliary slide rail is completely hidden in the main slide rail, which improves the aesthetics of the slide rail.

[0008] Preferably, a rotating shaft is provided on the side wall at one end of the auxiliary slide rail, and a sliding groove for the rotating shaft to slide into is opened on the first connecting block, and the sliding groove is connected to the inner side of the first connecting block; when the slide rail structure needs to change from a contracted state to an expanded state, the auxiliary slide rail slides a certain distance relative to the main slide rail, and the rotating shaft enters the slide groove from one end of the sliding groove, and then the rotating shaft rotates relative to the first connecting block. At this time, the auxiliary slide rail rotates relative to the first connecting block until the card block is inserted into the card groove.

[0009] By adopting the above technical solution, since the first connecting block does not need to guide the sliding of the auxiliary slide rail relative to the main slide rail throughout the entire process, the first connecting block does not need to be very long, saving material costs. At the same time, the first connecting block can stably guide the rotating shaft through the sliding groove, so that the auxiliary slide rail can stably rotate relative to the first connecting block.

[0010] Preferably, the slide groove includes a first horizontal groove, a connecting groove and a second horizontal groove which are connected in sequence, the first horizontal groove and the second horizontal groove are both arranged along the length direction of the main slide rail, one end of the first horizontal groove is connected to the inward side of the first connecting block, and the second horizontal groove is located above the outward side of the first horizontal groove; when the rotating shaft slides in the connecting groove, the secondary slide rail has a movement relative to the main slide rail along the height direction of the main desktop.

[0011] By adopting the above technical solution, the auxiliary slide rail and the main slide rail can have not only horizontal movement but also vertical movement. Therefore, when the slide rail structure is in the extended state, the auxiliary desktop can be at the same height as the main desktop, and when the slide rail structure is in the retracted state, the desktop can be stored under the main desktop. The comfort of the desktop is improved when the slide rail structure is in the extended state, and the concealment of the auxiliary desktop is ensured when the slide rail structure is retracted.

[0012] Preferably, the first horizontal groove has an inward end that is flared.

[0013] By adopting the above technical solution, the flared end of the first horizontal groove can play a guiding role, so that the rotating shaft can slide into the sliding groove more smoothly.

[0014] Preferably, the card slot includes a first card slot, a guide slot and a second card slot which are connected in sequence, the first card slot is connected to the upper end surface of the auxiliary slide rail, the second card slot is located below the outward side of the first card slot, and the second card slot is connected to the upper end wall of the guide slot; when the card block is inserted into the first card slot, the auxiliary slide rail slides inward relative to the main slide rail until the card block slides along the guide slot and is inserted into the second card slot, and at this time the rotating shaft slides in the second horizontal slot.

[0015] By adopting the above technical solution, the first clamping groove can ensure that the clamping block is clamped into the clamping groove, and the guide groove can play a role in buffering the transition, so that the clamping block can smoothly enter the second clamping groove. The second clamping groove cooperates with the guide groove to form an inverted hook design to ensure that the clamping block does not fall off or loosen. Thus, the auxiliary slide rail is stably fixed relative to the main slide rail.

[0016] When the card block is introduced into the card slot, the card block is restricted by the card slot. When it reaches the top, the secondary slide rail can only rotate upward relative to the first connecting block, and guide the card slot into the card block; the whole movement process is guided by the card block and the card slot limit, the operation is simple, and the secondary desktop will not have the problem of scratching up and down.

[0017] Preferably, a first limit block is provided on the first connecting block, and a second limit block is provided on the second connecting block; when the rotating shaft does not enter the slide groove, the first limit block abuts against the upper end surface of the auxiliary slide rail, and the second limit block abuts against the lower end surface of the auxiliary slide rail.

[0018] By adopting the above technical solution, the first limit block and the second limit block cooperate, so that the auxiliary slide rail is limited in the vertical direction relative to the main slide rail before the rotating shaft slides into the slide groove, so that the auxiliary slide rail can stably slide along the predetermined track relative to the main slide rail, ensuring that the rotating shaft can enter the slide groove. At the same time, the first limit block and the second limit block can also play the role of pressure support, so that the auxiliary slide rail can slide more stably relative to the main slide rail.

[0019] Preferably, the first limiting block is rotatably connected to the first connecting block, and the second limiting block is rotatably connected to the second connecting block.

[0020] By adopting the above technical solution, sliding friction is converted into rolling friction, the friction force is reduced, and the pushing and pulling process of the auxiliary slide rail relative to the main slide rail is smoother.

[0021] Preferably, a baffle for covering the notch of the receiving groove is provided at one end of the auxiliary slide rail; when the auxiliary slide rail is completely located in the receiving groove, the baffle abuts against one end of the main slide rail.

[0022] By adopting the above technical solution, the baffle can cover the accommodating groove, thereby improving the concealment of the auxiliary slide rail when the slide rail structure is in a retracted state.

[0023] In a second aspect, the present application provides a dining table, which adopts the following technical solution:

[0024] A dining table, comprising a main table top, a secondary table top and a slide rail, wherein the slide rail structure is as described in any one of claims 3-8, wherein the secondary table top is fixedly mounted on the upper end surface of the secondary slide rail, and the main table top is fixedly mounted on the upper end surface of the main slide rail via a connecting piece, wherein two secondary table tops are provided and are located on both sides of the main table top, wherein two secondary slide rails are provided, and one secondary slide rail corresponds to one secondary table top, and both secondary slide rails are located in one main slide rail.

[0025] By adopting the above technical solution, the adjustment range of the table top can be made larger, thereby improving the application range of the table.

[0026] Preferably, a gap is provided between the main desktop and the main slide rail; when the rotating shaft is not in the slide groove and the auxiliary slide rail is received in the accommodating groove, the auxiliary desktop is located below the main desktop and above the main slide rail; when the rotating shaft is in the second horizontal groove and the clamping block is located in the second clamping groove, the auxiliary desktop is located on one side of the main desktop, and the upper end surface of the auxiliary desktop and the upper end surface of the main desktop are located in the same plane.

[0027] By adopting the above technical solution, the secondary tabletop can be at the same height as the main tabletop when the dining table is in the expanded state, and the tabletop can be stored under the main tabletop when the dining table is in the retracted state. The comfort of the tabletop when the dining table is in the expanded state is improved, and the concealment of the secondary tabletop when the dining table is retracted is ensured. At the same time, when the dining table is in the expanded state, due to the cooperation of the card slot and the card block, the tabletop of the dining table is stable and not prone to warping or tipping.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Through the cooperation of the card slot and the card block, when the slide rail structure is in the unfolded state, the tabletop of the dining table is stable and not prone to warping or tipping;

[0030] 2. When the slide rail structure is in the unfolded state, the dining table top is at its maximum and all located on the same plane, which provides better comfort for use;

[0031] 3. When the slide rail structure is in the retracted state, the auxiliary table top is hidden under the main dining table, and the auxiliary slide rail is hidden in the main slide rail, which takes up little space and has a beautiful structure;

[0042] The following is combined with Figure 1-8 This application is described in further detail.

[0043] The present application embodiment discloses a dining table. Figure 1 and Figure 2 A dining table includes a main tabletop 1, a secondary tabletop 2 and a slide rail. Two secondary tabletops 2 are provided and are located on both sides of the main tabletop 1. The slide rail includes a main slide rail 3 for connecting the main tabletop 1 and a secondary slide rail 4 for connecting the secondary tabletop 2. The main tabletop 1 is fixedly mounted on the upper end surface of the main slide rail 3 through a connector 5, and a gap is provided between the main tabletop 1 and the main slide rail 3. Two secondary slide rails 4 are provided, and one secondary slide rail 4 corresponds to one secondary tabletop 2.

[0044] When the tabletop area to be used is small, the auxiliary slide rail 4 can be slid into the main slide rail 3. At this time, the auxiliary tabletop 2 is hidden between the main tabletop 1 and the main slide rail 3, the table is in a retracted state, and occupies a small space. When the tabletop area to be used is large, the auxiliary slide rail 4 can be slid to the extreme position relative to the main slide rail 3 toward the side away from the main slide rail 3. At this time, the auxiliary tabletop 2 is located on one side of the main tabletop 1, and the upper end surface of the auxiliary tabletop 2 is located on the same plane as the upper end surface of the main tabletop 1. The table is in an expanded state, occupies a large space, and can be used in more occasions.

[0045] Specifically, refer to Figure 2 and Figure 3Both ends of the main slide rail 3 are provided with receiving grooves 6 for receiving the auxiliary slide rail 4 along the length direction thereof. One auxiliary slide rail 4 corresponds to one receiving groove 6, and the auxiliary slide rail 4 is slidably connected to the receiving groove 6. Both side walls of the receiving groove 6 are installed with connecting block groups, and the connecting block groups include a first connecting block 7 and a second connecting block 8 installed at intervals on the side walls of the receiving groove 6. Figure 3 and Figure 4 , a rotating shaft 10 is provided on the side wall of one end of the auxiliary slide rail 4, and a slide groove 9 for the rotating shaft 10 to slide into is provided on the first connecting block 7. The slide groove 9 includes a first horizontal groove 11, a connecting groove 12 and a second horizontal groove 13 which are connected to each other from one end close to the center of the main slide rail 3 to one end away from the center of the main slide rail 3. The first horizontal groove 11 and the second horizontal groove 13 are both arranged along the length direction of the main slide rail 3, one end of the first horizontal groove 11 is connected to the inward side of the first connecting block 7, and the inward end of the first horizontal groove 11 is expanded. The second horizontal groove 13 is located above the outward side of the first horizontal groove 11.

[0046] When the dining table is to be changed from the retracted state to the expanded state, the secondary slide rail 4 slides relative to the main slide rail 3 toward the side away from the main slide rail 3. At this time, the rotating shaft 10 first slides a certain distance in the receiving groove 6, and then enters the slide groove 9 through the first horizontal groove 11, and slides along the slide groove 9 until the rotating shaft 10 abuts against the end of the second horizontal groove 13 away from the first horizontal groove 11. In this process, the secondary slide rail 4 not only moves horizontally, but also moves vertically upward. The demand for the secondary desktop 2 to move from the bottom of the main desktop 1 to the side of the main desktop 1 is realized.

[0047] Reference Figure 4 and Figure 5 In order to keep the dining table stably in the unfolded state, a slot 14 is provided on the secondary slide rail 4, and a block 15 for being inserted into the slot 14 is provided on the second connecting block 8. The block 15 is cylindrical. The slot 14 includes a first engaging slot 16, a guide slot 17, and a second engaging slot 18 which are connected to each other in sequence from the end close to the center of the main slide rail 3 to the end far from the center of the main slide rail 3. The first engaging slot 16 is connected to the upper end surface of the secondary slide rail 4, and the second engaging slot 18 is located below the outward side of the first engaging slot 16, and the second engaging slot 18 is connected to the upper end wall of the guide slot 17. The slot 14 is formed into an inverted hook shape as a whole.

[0048] When the clamping block 15 is inserted into the first clamping groove 16, the auxiliary slide rail 4 slides inward relative to the main slide rail 3 until the clamping block 15 slides along the guide groove 17 and is inserted into the second clamping groove 18. At this time, the rotating shaft 10 slides in the second horizontal groove 13. The second clamping groove 18 cooperates with the guide groove 17 to form an inverted hook design to ensure that the clamping block 15 is stably located in the clamping groove 14. In this way, the auxiliary slide rail 4 is fixed relative to the main slide rail 3, and the dining table can be stably maintained in the unfolded state.

[0049] Reference Figure 3 and Figure 4In order to make the auxiliary slide rail 4 slide more stably relative to the main slide rail 3, the first connection block 7 is provided with a first limit block 19, the first limit block 19 is cylindrical, and the first limit block 19 is rotatably connected to the first connection block 7. The second connection block 8 is provided with a second limit block 20, the second limit block 20 is cylindrical, and the second limit block 20 is rotatably connected to the first connection block 7.

[0050] When the rotating shaft 10 does not enter the slide groove 9, the first limit block 19 abuts against the upper end surface of the auxiliary slide rail 4, and the second limit block 20 abuts against the lower end surface of the auxiliary slide rail 4. The first limit block 19 and the second limit block 20 cooperate so that the auxiliary slide rail 4 is vertically limited relative to the main slide rail 3 before the rotating shaft 10 slides into the slide groove 9, so that the auxiliary slide rail 4 can stably slide along the predetermined track relative to the main slide rail 3, ensuring that the rotating shaft 10 can enter the slide groove 9. There is rolling friction between the first limit block 19 and the second limit block 20 and the auxiliary slide rail 4, and the friction force is small, so that the auxiliary slide rail 4 can slide smoothly relative to the main slide rail 3.

[0051] Reference Figure 3 In order to improve the concealment of the auxiliary rail 4, a baffle 21 for shielding the notch of the receiving groove 6 is provided at one end of the auxiliary rail 4. When the auxiliary rail 4 is completely located in the receiving groove 6, the baffle 21 abuts against one end of the main rail 3 and closes the receiving groove 6.

[0052] The implementation principle of a dining table in the embodiment of the present application is:

[0053] 1. The dining table has two states, expanded state and contracted state;

[0054] 2. When the dining table is in the retracted state, the secondary tabletop is hidden under the main tabletop, and the dining tabletop is smaller; at this time, refer to Figure 6 , the auxiliary slide rail 4 is completely located in the receiving groove 6 and abuts against the inner bottom surface of the receiving groove 6, the baffle 21 abuts against one end of the main slide rail 3 and closes the receiving groove 6, the rotating shaft 10 does not slide into the slide groove 9, and the block 15 does not slide into the card groove 14;

When the dining table is in the retracted state, the auxiliary table top 2 is located on the side of the main table top 1, and the upper end surface of the auxiliary table top 2 is located on the same plane as the upper end surface of the main table top 1, and the dining table top is larger; at this time, refer to Figure 8 , the auxiliary slide rail 4 abuts against the top surface of the receiving groove 6, the rotating shaft 10 is located in the second horizontal groove 13, and the clamping block 15 is clamped in the second clamping groove 18;

[0056] 4. When the dining table needs to be transformed from the collapsed state to the expanded state, refer to Figures 6 to 8, pull the secondary table top 2 to slide outward relative to the main table top 1, at this time, the secondary slide rail 4 slides relative to the main slide rail 3 toward the side away from the main slide rail 3, the rotating shaft 10 first slides in the accommodating groove 6, and then enters the slide groove 9 through the first horizontal groove 11, and slides along the slide groove 9 until the rotating shaft 10 abuts against the second horizontal groove 13 away from the first horizontal groove 11. The secondary slide rail 4 continues to slide relative to the main slide rail 3 until the block 15 is aligned with the first engaging groove 16, and the secondary table top 2 is rotated relative to the main table top 1, and then the secondary slide rail 4 is rotated relative to the first connecting block 7, so that the block 15 is engaged in the first engaging groove 16; finally, the secondary slide rail 4 is slid relative to the main slide rail 3 toward the side close to the main slide rail 3 until the block 15 is engaged in the second engaging groove 18, so that the secondary slide rail 4 and the main slide rail 3 are relatively fixed, so that the dining table is transformed from the retracted state to the expanded state, and stably maintained in the expanded state.
