Abstract
Description
Technical Field
[0001] This application relates to a buffer slide rail, and more particularly to an extension table and its buffer slide rail. Background Technology
[0002] In existing extension table designs, heavy-duty guide rails are commonly used to pull out the tabletop. However, these traditional structures have some obvious drawbacks: First, most designs lack effective damping mechanisms, making it easy for users to pull out the tabletop with excessive force or completely remove it, causing the tabletop to separate from the table body. This not only causes inconvenience but also poses a risk of the tabletop falling, injuring people, or causing damage, resulting in insufficient safety and reliability.
[0003] Furthermore, existing technologies often lack precise damping mechanisms during the tabletop retraction process. This makes it difficult for the tabletop to accurately return to its initial position after retraction, frequently resulting in misalignment between the tabletop and the table frame. This misalignment not only affects the overall aesthetics of the table, disrupting the furniture's sense of unity and design, but may also cause parts of the tabletop to be suspended in mid-air, affecting stability and comfort during use. Utility Model Content
[0004] This application provides an extension table and its buffer slide rail to solve the problems existing in related technologies. The technical solution is as follows:
[0005] In a first aspect, embodiments of this application provide a buffer slide rail, including:

[0011] The slide rail has a first state and a second state.
[0012] When the slide rail is in the first state, the first limiting member is in contact with the buffer assembly, while the second limiting member is not in contact with the buffer assembly.
[0013] When the slide rail is in the second state, the second limiting member is in contact with the buffer assembly, while the first limiting member is not in contact with the buffer assembly.

[0039] The advantages or beneficial effects of the above technical solutions include at least the following:
[0040] By using a buffer component in conjunction with the first and second limiting components, the table body and desktop can be easily pulled out and extended, while the desktop is locked relative to the table body to prevent it from being pulled out excessively and separating from the table body. At the same time, the desktop is limited when it is retracted to ensure that the surface of the table body is flush after the desktop is retracted, thus enhancing the aesthetics.

[0055] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0056] Figures 1-3 A structural diagram of a buffer slide rail according to an embodiment of this application is shown. Figures 1-3 As shown, the buffer slide rail may include:
[0057] Support frame 100;
[0058] The slide rail 200 is mounted on the support frame 100.
[0059] A buffer assembly 300 is mounted on a support frame 100.
[0060] The first limiting member 400 is disposed on the slide rail 200;
[0061] The second limiting member 500 is disposed on the slide rail 200, and the first limiting member 400 and the second limiting member 500 are respectively disposed at both ends of the slide rail 200 near the end.
[0062] The slide rail 200 has a first state and a second state;
[0063] When the slide rail 200 is in the first state, the first limiting member 400 is in contact with the buffer assembly 300, and the second limiting member 500 is not in contact with the buffer assembly 300.
[0064] When the slide rail 200 is in the second state, the second limiting member 500 is in contact with the buffer assembly 300, while the first limiting member 400 is not in contact with the buffer assembly 300.
[0065] In this embodiment, during use, the slide rail 200 is connected to the desktop 900 of the extension table. The slide rail 200 is slidably connected to the support frame 100, thereby enabling the desktop 900 and table body 800 to be pulled out. The buffer component 300 locks the desktop 900 when it is pulled out or retracted. When the slide rail 200 is in the first state, the first limiting member 400 contacts the buffer component 300, while the second limiting member 500 does not contact the buffer component 300. When the slide rail 200 is in the second state, the second limiting member 500 contacts the buffer component 300, while the first limiting member 400 does not contact the buffer component 300.
[0066] Specifically, the first state of the slide rail 200 is the state in which the desktop 900 is pulled out and used. At this time, the buffer component 300 contacts the first limiting component 400, thereby locking the desktop 900 in the state of pulling out the table body 800. The second state of the slide rail 200 is the state in which the desktop 900 is not used. At this time, the desktop 900 and the table body 800 form a cuboid structure with a flush surface, ensuring the flush surface of the table body 800.
[0067] By using the buffer component 300 in conjunction with the first limiting component 400 and the second limiting component 500, the table body 800 and the desktop 900 can be easily pulled out and extended, while the desktop 900 is locked relative to the table body 800 to prevent the desktop 900 from being pulled out excessively and separating from the table body 800. At the same time, the desktop 900 is limited when it is retracted to ensure that the surface of the table body 800 is flush after the desktop 900 is retracted, thus enhancing the aesthetics.
[0068] like Figures 2-3 As shown, in one embodiment,
[0069] Buffer component 300 includes:
[0070] The outer casing 310 is mounted on the support frame 100 and has a first receiving cavity 320 and a second receiving cavity 330.
[0071] The first clamping member 340 is disposed in the first accommodating cavity 320. When the slide rail 200 is in the first state, the first limiting member 400 contacts the first clamping member 340.
[0072] The second clamping member 350 is disposed in the second accommodating cavity 330. When the slide rail 200 is in the second state, the second limiting member 500 contacts the second clamping member 350.
[0073] Two buffer cylinders 380 are provided on the outer shell 310, and the movable ends of the two buffer cylinders 380 are respectively provided on the first clamping member 340 and the second clamping member 350.
[0074] Two springs 390 are respectively disposed in the first accommodating cavity 320 and the second accommodating cavity 330.
[0075] In this embodiment, the first clamping member 340 slides within the first accommodating cavity 320, and the second clamping member 350 slides within the second accommodating cavity 330. When the slide rail 200 is in the first state, the first clamping member 340 clamps the first limiting member 400. When the slide rail 200 is in the second state, the second clamping member 350 clamps the second limiting member 500.
[0076] Specifically, when the slide rail 200 is in the first state, one end of the slide rail 200 with the second limiting member 500 extends to the outside of the table body 800, and one end of the slide rail 200 with the first limiting member 400 is flush with the end of the support frame 100 away from the second limiting member 500.
[0077] When the slide rail 200 is in the second state, one end of the slide rail 200 with the second limiting member 500 is flush with the end of the support frame 100 away from the first limiting member 400.
[0078] Furthermore, both the first clamping member 340 and the second clamping member 350 are provided with protrusions 360, and the outer shell 310 has a first sliding groove 311 and a second sliding groove 312 corresponding to the protrusions 360. The protrusions 360 on the first clamping member 340 and the second clamping member 350 are respectively located in the first sliding groove 311 and the second sliding groove 312.
[0079] The protrusions 360 on the first clamping member 340 and the second clamping member 350 slide in the first slide groove 311 or the second slide groove 312 respectively, thereby limiting the movement trajectory of the first clamping member 340 and the second clamping member 350.
[0080] Specifically, the first slide groove 311 and the second slide groove 312 are respectively connected to the first accommodating cavity 320 and the second accommodating cavity 330. Both the first slide groove 311 and the second slide groove 312 have bent portions, which are respectively directed toward the two ends of the outer shell 310.
[0081] When the protrusions 360 on the first clamping member 340 or the second clamping member 350 move along the first slide groove 311 or the second slide groove 312 to the bending part, the first clamping member 340 and the second clamping member 350 rotate under the action of the first slide groove 311 or the second slide groove 312. The first clamping member 340 and the second clamping member 350 are each provided with four protrusions 360. The first slide groove 311 and the second slide groove 312 are each provided with two. The two first slide grooves 311 and the two second slide grooves 312 are symmetrically arranged about the first accommodating cavity 320 and the second accommodating cavity 330, respectively, to ensure the stability of the movement of the first clamping member 340 and the second clamping member 350.
[0082] Specifically, the bends of the first slide groove 311 and the second slide groove 312 are both smooth corners, ensuring the stability of the protrusion 360° movement;
[0083] When the protrusion 360 is located at the bend, the first clamping member 340 and the second clamping member 350 are partially housed in the corresponding first receiving cavity 320 and second receiving cavity 330.
[0084] The two bent portions of the first slide groove 311 and the second slide groove 312 are respectively oriented toward the two ends of the outer casing 310, so as to facilitate the switching of the first state and the second state of the slide rail 200;
[0085] During the switching process between the first state and the second state of the slide rail 200, one of the buffer cylinders 380 pushes the first clamping member 340 or the second clamping member 350 to the bending part of the first slide groove 311 or the second slide groove 312 in advance, while the other buffer cylinder 380 retracts the first clamping member 340 or the second clamping member 350, so that the first clamping member 340 or the second clamping member 350 disengages from the bending part of the first slide groove 311 or the second slide groove 312.
[0086] When the buffer cylinder 380 retracts, it abuts against the first clamping member 340 or the second clamping member 350 through the spring 390, thereby damping and absorbing the impact force when the buffer cylinder 380 moves, thus achieving a damping effect.
[0087] like Figures 2-3 As shown, in one embodiment, it further includes:
[0088] Two fixing blocks 370 are respectively disposed on the first limiting member 400 and the second limiting member 500. The first clamping member 340 and the second clamping member 350 have grooves adapted to the two fixing blocks 370. When the slide rail 200 is in the first state, the fixing block 370 on the first limiting member 400 is located in the groove of the first clamping member 340. When the slide rail 200 is in the second state, the fixing block 370 on the second limiting member 500 is located in the groove of the second clamping member 350.
[0089] In this embodiment, the shapes of the first clamping member 340 and the second clamping member 350 are the same as the clamping end shape of the pliers;
[0090] Specifically, both the first clamping member 340 and the second clamping member 350 have beveled edges on the side facing the corresponding fixing block 370, with the beveled edges facing the two ends of the outer casing 310. When the tabletop 900 is pulled outward, the protrusion on the first limiting member 400 contacts the portion of the first clamping part located outside the first accommodating cavity 320, and pushes the first clamping member 340 along the first sliding groove 311, thereby causing the fixing block 370 on the first limiting member 400 to enter the groove of the first clamping member 340. At the same time, the second limiting member 500 moves outward, pushing the second limiting member 500 to the bending portion of the second sliding groove 312, causing the second clamping member 350 to flip under the action of the bending portion, so that the fixing block 370 on the second limiting member 500 disengages from the groove on the second clamping member 350. When the tabletop 900 is pushed inward, the second limiting member 500 and the first limiting member 400 can move in opposite directions as described above.
[0091] like Figures 2-3 As shown, in one embodiment, it further includes:
[0092] Several pulleys 600 are mounted on the support frame 100 and slide within the slide rail 200.
[0093] In this embodiment, the pulley 600 rotates within the slide rail 200 to ensure the smooth movement of the slide rail 200 and the support frame 100.
[0094] In one implementation, it further includes:
[0095] The sealing element 700 is installed at both ends of the slide rail 200.
[0096] In this embodiment, by setting the sealing component 700, the two ends of the slide rail 200 are indexed, thereby limiting the movement distance of the slide rail 200, and thus limiting the movement distance of the desktop 900.
[0097] Figure 1 A structural diagram of an extension table according to an embodiment of this application is shown. Figure 1 As shown, the extended table may include:
[0098] A buffer slide rail as described in any of the above embodiments; and
[0099] The table body 800 and the support frame 100 are mounted on the table body 800;
[0100] The desktop 900 and the slide rail 200 are set on the desktop 900. The desktop 900 is slidably set on the desktop 900 through the slide rail 200 and the support frame 100. When the slide rail 200 is in the first state, the desktop 900 extends relative to the table body 800. When the slide rail 200 is in the second state, the desktop 900 retracts relative to the table body 800.
[0101] In this embodiment, the first state of the slide rail 200 is the state in which the desktop 900 is pulled out and used. At this time, the buffer component 300 contacts the first limiting member 400, thereby locking the desktop 900 in the state of pulling out the table body 800. The second state of the slide rail 200 is the state in which the desktop 900 is not used. At this time, the desktop 900 and the table body 800 form a cuboid structure with a flush surface, ensuring the flush surface of the table body 800.
[0102] like Figure 1 As shown, in one embodiment,
[0103] The desktop 900 has a recess, and the slide rail 200 is set in the recess.
[0104] In this embodiment, by setting a recess on the desktop 900, the slide rail 200 can be hidden at the bottom of the desktop 900, which not only ensures aesthetics but also facilitates the movement of the desktop 900.
[0105] The functions of each module in each device of this utility model embodiment can be found in the corresponding description in the above method, and will not be repeated here.
