Description

Technical Field

[0001] This utility model relates to the field of quick-connect fittings technology, and in particular to a quick-connect mechanism. Background Technology

[0002] Most quick-connect structures currently use snap-fit ​​mechanisms, but after the male and female snap-fit ​​mechanisms are connected, there will be some gaps, which can cause the two components to loosen or wobble slightly.

[0003] For example, when the armrests of furniture chairs are assembled using a snap-fit ​​structure, gaps exist in the assembly method, resulting in wobbling after assembly and poor stability. Utility Model Content

[0004] The purpose of this invention is to provide a quick connection mechanism that uses the close contact between the first plate and the second plate to limit their relative positions, thereby improving the tightness and precision of the connection, making it less prone to shaking and providing good stability.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A quick-connect mechanism includes a first component and a second component;

[0007] The first component includes a first plate and a drive bar;

[0008] The second component includes a second plate, clamping elements, and bolts;

[0009] The drive bar and the clamping element are connected by a gear structure;

[0010] The clamping parts and bolts are connected by a threaded structure;

[0011] When the first plate is in the first position, the clamping member moves away from the first plate, and the first plate and the second plate are in a loosened state;

[0012] When the second plate is in the second position, the clamping member abuts against the first plate and causes the first plate and the second plate to be in a tight fit, thereby defining the relative position between the first plate and the second plate.

[0013] In some embodiments, as the first plate moves from the first position to the second position, the drive bar drives the clamping member to rotate through the gear structure, and the clamping member moves closer to the first plate under the action of the threaded structure, thereby pushing the first plate to move closer to the second plate.

[0014] As the first plate moves from the second position to the first position, the drive bar drives the clamping member to rotate in the opposite direction through the gear structure, and the clamping member gradually moves away from the first plate under the action of the thread structure, thereby causing the first plate to loosen from the second plate.

[0015] In some embodiments, as the first plate moves from the first position to the second position, the first plate is located between the clamping member and the second plate.

[0016] In some embodiments, the drive bar is provided with a rack portion, and the outer peripheral surface of the clamping member is provided with an external tooth portion that mates with the rack portion;

[0017] The clamping component has a first screw hole, and the bolt has a first threaded section that mates with the first screw hole.

[0018] In some implementations, the drive bar is connected to the first plate.

[0019] The bolts are vertically connected to the second plate.

[0020] In some embodiments, the first component further includes a third countersunk screw, which passes through a third countersunk hole in the drive bar and is screwed into a third screw hole in the first plate.

[0021] The bolt is also provided with a second threaded section, and the second plate is provided with a second threaded hole that mates with the second threaded section.

[0022] In some embodiments, the first plate has an opening through which the clamping member can pass;

[0023] The first plate is provided with a guide groove, which is connected to the opening. The width of the guide groove is greater than the diameter of the first threaded section.

[0024] The second plate is provided with a guide protrusion that cooperates with the guide groove.

[0025] In some embodiments, the guide groove is arranged parallel to the rack portion.

[0026] In some embodiments, the drive bar also has a fence portion, which is arc-shaped and located on the side of the opening away from the guide groove.

[0027] In some embodiments, both the first plate and the second plate are elongated, with the clamping member located at the upper end of the second plate and the opening located at the lower end of the first plate.

[0028] The beneficial effects of this utility model are: by using the first plate and the second plate to fit together to limit their relative positions, the tightness and precision of the connection are improved, making it less prone to shaking and more stable.

[0029] Furthermore, the clamping component, through the synergistic action of the gear structure and the thread structure, enables the clamping component to move away from and towards the two plates as they move relative to each other, thereby achieving convenient switching between the loose and tight states between the two plates and facilitating assembly.

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] refer to Figures 1 to 4 A quick-connect mechanism, comprising a first component 1 and a second component 2;

[0041] The first component 1 includes a first plate body 11 and a driving bar 12;

[0042] The second component 2 includes a second plate body 21, a pressing member 22 and a bolt 23;

[0043] The driving bar 12 and the pressing member 22 are connected by a gear structure;

[0044] The pressing member 22 and the bolt 23 are connected by a threaded structure;

[0045] When the first plate body 11 is at the first position P1, the pressing member 22 is away from the first plate body 11, and the first plate body 11 and the second plate body 21 are in a loose state. The loose state can be understood as: there is a gap between the first plate body 11 and the second plate body 21, having a certain movement space, and the two can move relatively freely between them.

[0046] When the second plate body 21 is at the second position P2, the pressing member 22 abuts against the first plate body 11 and urges the first plate body 11 and the second plate body 21 to be in a close state, thereby fixing or limiting the relative position between the first plate body 11 and the second plate body 21. The close state can be understood as: the first plate body 11 and the second plate body 21 are fitted together under a certain pressure.

[0047] Thus, by using the close contact between the first plate body 11 and the second plate body 21 to limit their relative positions, it is beneficial to improve the tightness of the connection between the first plate body 11 and the second plate body 21, with higher connection accuracy. Since there is no gap or the gap is very small between the first plate body 11 and the second plate body 21, it is more difficult for the two plate bodies to shake.

[0048] Furthermore, when the first plate body 11 moves from the first position P1 to the second position P2, the driving bar 12 drives the pressing member 22 to rotate through the gear structure, and the pressing member 22 moves gradually closer to the first plate body 11 under the action of the threaded structure, thereby pushing the first plate body 11 to move gradually closer to the second plate body 21; that is, it urges the gap between the first plate body 11 and the second plate body 21 to gradually become smaller. When the first plate body 11 reaches the second position P2, the first plate body 11 and the second plate body 21 are in a close state.

[0049] When the first plate body 11 moves from the second position P2 to the first position P1, the driving bar 12 drives the pressing member 22 to rotate in the reverse direction through the gear structure, and the pressing member 22 moves gradually away from the first plate body 11 under the action of the threaded structure, thereby causing the first plate body 11 and the second plate body 21 to loosen; that is, it urges the movable gap between the first plate body 11 and the second plate body 21 to gradually become larger.

[0050] Therefore, during the relative movement between the first plate 11 and the second plate 21, the synergistic effect of the gear structure and the thread structure enables the clamping member 22 to move away from and closer to the first plate 11, thereby achieving convenient switching between the loosened state and the tight state.

[0051] Furthermore, as the first plate 11 moves from the first position P1 to the second position P2, the first plate 11 is positioned between the clamping member 22 and the second plate 21. That is, the clamping member 22 and the second plate 21 form a structure that clamps the first plate 11. This can be understood as follows: the clamping member 22 presses against the first plate 11, and the first plate 11 presses against the second plate 21. Thus, in the tightly pressed state, the three parts are tightly pressed against each other, making the positional constraint between the first plate 11 and the second plate 21 more stable.

[0052] refer to Figure 1 and Figure 2 The drive bar 12 is provided with a rack portion 121, which is arranged along the direction from the first position P1 to the second position P2; the clamping member 22 may be circular, and the outer peripheral surface of the clamping member 22 is provided with an external tooth portion 221 that cooperates with the rack portion 121.

[0053] The clamping member 22 is provided with a first screw hole 222, and the bolt 23 is provided with a first threaded section 231 that mates with the first screw hole 222. In this way, the connection through the threaded structure makes the clamping member 22 more accurate in moving closer and further away, and the threaded structure has a better self-locking force, which makes it less likely to loosen when it is in a tight state.

[0054] refer to Figure 1 and Figure 2 The drive bar 12 is connected to the first plate 11, and the rack portion 121 of the drive bar 12 moves with the movement of the first plate 11.

[0055] Bolt 23 is vertically connected to the second plate 21, causing the clamping member 22 to contact the first plate 11 in a surface-to-surface manner, thereby improving stability.

[0056] The first component 1 also includes a third countersunk screw 13, which passes through the third countersunk hole 123 of the drive bar 12 and is screwed into the third screw hole 113 of the first plate 11; the drive bar 12 is assembled to the first plate 11 by a screw structure.

[0057] Bolt 23 is also provided with a second threaded section 232, and the second plate 21 is provided with a second threaded hole 212 that mates with the second threaded section 232. Bolt 23 is assembled to the second plate 21 by means of a threaded structure.

[0058] refer to Figure 1 and Figure 2The first plate 11 has an opening 111, through which the clamping member 22 can pass; the diameter of the opening 111 is larger than the diameter of the clamping member 22, so that the clamping member 22 can freely pass through or enter the opening 111.

[0059] The first plate 11 is provided with a guide groove 112, which is connected to the opening 111. The width of the guide groove 112 is slightly larger than the diameter of the first threaded section 231, thereby forming a space for the relative movement of the first threaded section 231, that is, it does not hinder the relative movement between the first threaded section 231 and the first plate 11.

[0060] The second plate 21 is provided with a guide protrusion 211 that cooperates with the guide groove 112. The guide groove 112 is arranged along the direction from the first position P1 to the second position P2, and the guide groove 112 and the guide protrusion 211 cooperate to form a guide structure, which improves the accuracy of the relative movement between the first plate 11 and the second plate 21; when the guide protrusion 211 and the first threaded section 231 both enter the guide groove 112, the relative angle between the first plate 11 and the second plate 21 can be limited.

[0061] The guide groove 112 is arranged parallel to the rack portion 121, and the rack portion 121 is located on one side of the guide groove 112.

[0062] refer to Figure 1 and Figure 2 The drive bar 12 is also provided with a fence section 122, which is arc-shaped and located on the side of the opening away from the guide groove 112.

[0063] The fence portion 122 can be configured as a semi-circular arc or a U-shape, and is set along the edge of the opening, so that the clamping member 22 cannot go beyond the fence portion 122, and the clamping member 22 or the first plate 11 can more easily find the first position P1.

[0064] Both the first plate 11 and the second plate 21 are elongated strips, which can be understood as rectangular; the clamping member 22 is located at the upper end of the second plate 21, and the opening 111 is located at the lower end of the first plate 11.

[0065] The elongated design facilitates relative movement along its length, and when the first plate 11 and the second plate 21 are in close contact, it ensures a large contact area between the first plate 11 and the second plate 21, resulting in a more stable close contact.

[0066] Working principle:

[0067] During assembly:

[0068] refer to Figure 5 The opening 111 of the first component 1 is fitted into the clamping member 22 of the second component 2, causing the clamping member 22 to be located inside the opening 111. At this time, the first plate 11 is located in the first position P1.

[0069] The first plate 11 is pushed to move to the second position P2, that is, to move along the A1 direction. During the movement, the rack part 121 drives the clamping member 22 to rotate. At the same time, the clamping member 22 moves closer to the first plate 11 under the action of the thread structure, that is, to move along the B1 direction, thereby pushing the first plate 11 closer to the second plate 21 and gradually reducing the gap between the two plates.

[0070] When the first plate 11 moves to the second position P2, the clamping member 22 abuts against the first plate 11 and causes the first plate 11 and the second plate 21 to be in a tight fit, thereby realizing the relative position between the first plate 11 and the second plate 21, thus completing a quick and convenient connection and assembly.

[0071] The first position P1 can be understood as the position of the clamping member 22 when it is located inside the opening 111;

[0072] The second position P2 can be understood as follows: the first plate 11 moves in the direction of A1 until the first plate 11 can hardly move in the direction of A1 anymore, that is, the clamping member 22 moves close to the upper end of the guide groove 112. At this time, there is basically no gap between the first plate 11 and the second plate 21, which meets the assembly requirements.

[0073] During unloading:

[0074] refer to Figure 6 An external force is applied to cause the first plate 11 to move to the first position P1, that is, to move along the A2 direction. During the movement, the rack part 121 drives the clamping member 22 to rotate in the opposite direction. At the same time, the clamping member 22 moves away from the first plate 11 under the action of the thread structure, that is, it moves along the B2 direction, thereby causing the movable gap between the first plate 11 and the second plate 21 to gradually increase.

[0075] When the first plate 11 moves to the first position P1, the first plate 11 and the second plate 21 are in a loose state, and the clamping member 22 is located in the opening 111. Then, the opening 111 is disengaged from the clamping member 22, thereby separating the first component 1 from the second component 2 and completing the quick and convenient disassembly and assembly.

[0076] The aforementioned quick-connect mechanism can be applied to the connection or docking of two objects, thereby achieving quick and convenient connection and assembly.

[0077] For example:

[0078] refer to Figures 7 to 10 It is applied to seat 200, and the armrest 220 of seat 200 is assembled to seat 210 of seat 200 through quick connection mechanism.

[0079] The first plate 11 of the first component 1 may be provided with a first countersunk hole 113, and the first plate 11 is assembled to the handrail 220 by the first countersunk screw 3.

[0080] The second plate 21 of the second component 2 may be provided with a second countersunk hole 213, and the second plate 21 is assembled to the base 210 by a second countersunk screw 4.

[0081] During assembly, the first component 1 is pushed downwards, causing the first plate 11 and the second plate 21 to be in close contact, thereby connecting to the second component 2 and achieving quick and convenient assembly;

[0082] During disassembly, the first component 1 is pushed upward, causing the first plate 11 and the second plate 21 to be in a loose state, thereby separating from the second component 2, achieving quick and convenient disassembly.

[0083] Of course, seat 200 can be a home chair, office chair, sofa, massage chair, beauty chair, etc.

[0084] Similarly, the backrest of seat 200 is also assembled to seat 210 of seat 200 via a quick-connect mechanism.

[0085] Similarly, the headboard or guardrails of the bed are also assembled to the bed frame via a quick-connect mechanism.

[0086] Similarly, furniture products also use quick-connect mechanisms to assemble two components.

[0087] Of course, quick-connect mechanisms can also be applied to products that connect or dock components.

[0088] Therefore, the quick-connect mechanism of this application has the following functions: it can be repeatedly installed and disassembled, is easy to install, can be locked firmly without screws, has strong load-bearing capacity, and is thin in size.

[0089] Application scenarios: Suitable for various industrial products.

[0090] 1. Applicable to the assembly of various furniture parts or components (e.g., sofas, armrests, seats, and backrests can be fully disassembled and securely assembled), convenient to produce, small packaging size, and saves logistics and warehousing costs.

[0091] 2. Modular building formwork bridges are quick and securely assembled.

[0092] 3. All kinds of machinery, equipment and industrial products are quick-assembled and securely fitted.

[0093] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
