Description

Technical Field

[0001] The present application relates to the technical field of connection structure devices, and in particular to a profile quick-disassembly connector. Background Art

[0002] Profiles are typically made of aluminum, aluminum alloy, or plastic-steel. They consist of multiple plates connected to form a defined cross-section. They are non-solid structures, which are lighter, less expensive, and easier to transport than solid plates and columns. Each plate within the profile is split, has multiple bends, or is reinforced with ribs, giving the profile greater structural strength and stability.

[0003] In the prior art, profiles are used as supporting structures in products such as window frames, appliance frames, and mobile stages. These profiles are disassembled during transportation, and rivets and angle irons are used as quick connectors to connect the profiles to each other after arriving at the installation site. However, this connection method is a non-detachable connection that involves destructive assembly and disassembly, making it unsuitable for repeated assembly and disassembly. Although electric screwdrivers and screws can be used to connect profiles instead of rivets, the use of screws will cause pressure and deformation accumulation at the profile joints, and the number of such disassembly and assembly times is still limited.

[0004] Therefore, there is an urgent need for a connecting device that can ensure that the profiles can be repeatedly disassembled and assembled, and can also ensure that the profiles are stably connected. Utility Model Content

[0005] The present invention mainly aims at the above problems and proposes a profile quick disassembly connector, aiming to solve the technical problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides a profile quick-disassembly connector, which is used for profile connection, the profile is provided with a connecting groove, the end of the connecting groove is connected to the end opening of the profile, and a closing block strip is provided at the notch of the connecting groove. The profile quick-disassembly connector includes a plug-in base and a locking strip, and the plug-in base includes a first plug-in section and a second plug-in section that are connected to each other; the first plug-in section and / or the second plug-in section are provided with a receiving groove; the locking strip is arranged in the receiving groove, one end of which is rotatably connected to the first plug-in section and / or the second plug-in section, and the outer wall of the locking strip at the rotating connection is provided with an eccentric protrusion; the plug-in base corresponds to the eccentric protrusion and is provided with an avoidance through-hole on the bottom wall of the receiving groove; when the locking strip rotates a first predetermined angle relative to the plug-in base, the eccentric protrusion enters the avoidance through-hole and extends out of the end face of the bottom wall of the plug-in base; when the locking strip rotates a second predetermined angle relative to the plug-in base, the eccentric protrusion withdraws from the avoidance through-hole.

[0007] Furthermore, sliding chamfers are provided at both ends of the plug-in base plate.

[0008] Furthermore, a locking screw is included, and a screw connection hole is opened on the bottom wall of the accommodating groove.

[0009] Furthermore, a reference portion is provided at the junction of the first plug-in section and the second plug-in section.

[0010] Furthermore, it includes a rotating shaft connected to the plug-in base plate, and the locking strip is connected to the plug-in base plate through the rotating shaft.

[0011] Furthermore, when the locking strip is rotated relative to the plug-in base plate by a first predetermined angle, the locking strip is received in the plug-in base plate.

[0012] Furthermore, when the locking strip is rotated relative to the plug-in base plate by a second predetermined angle, the locking strip is away from the end connected to the plug-in base plate, and the end is away from the accommodating groove.

[0013] Furthermore, the first plug-in section and the second plug-in section are connected in a straight line;

[0014] Alternatively, an angle corresponding to the relative connection positions of the two profiles is provided between the first plug-in section and the second plug-in section.

[0015] Furthermore, it comprises a connecting block connected to the plug-in base plate, and used for connecting at least two of the profile quick-disconnect connectors in parallel into one.

[0016] Furthermore, it includes a fin plate connected to the plug-in base plate and / or the connecting block, and the cross-sectional profile of the fin plate at least corresponds to the profile of the outer area of ​​the cross-sectional area of ​​the profile.

[0017] Compared with the prior art, the utility model provides a profile quick disassembly connector, which can not only realize the quick connection between profiles, but also realize quick disassembly. Moreover, the profile connection and alignment are carried out simultaneously, which is more convenient and quicker than the prior art in which the profiles are aligned first and then rivets or screws are driven in for connection. The size of the plug-in base plate and the size of the connection groove can be a transition fit relationship. When the length of the plug-in base plate is long enough, the friction between the plug-in base plate and the connection groove is high enough, and the pressing force of the eccentric protrusion on the profile surface is high enough, then the stability of this connection strength is fully competent for profile frame structures that are temporarily built, used at low intensity, and require repeated disassembly and assembly.

[0028] Please refer to Figure 1 - Figure 6 The present embodiment provides a profile quick-disassembly connector, which is used for connecting a profile 1. The profile 1 is provided with a connecting groove 110. The end of the connecting groove 110 is connected to the end opening 120 of the profile 1. The notch of the connecting groove 110 is provided with a closing block 111. The profile quick-disassembly connector includes a plug-in base 2 and a locking strip 3. The plug-in base 2 includes a first plug-in section 210 and a second plug-in section 220 that are connected to each other; the first plug-in section 210 and / or the second plug-in section 220 are provided with a receiving groove 2 15; the locking strip 3 is disposed in the accommodating groove 215, with one end being rotatably connected to the first plug-in section 210 and / or the second plug-in section 220, and the locking strip 3 is provided with an eccentric protrusion 310 on the outer wall of the rotatable connection; the plug-in base plate 2 is provided with a position-avoiding through-hole 230 on the bottom wall of the accommodating groove 215 corresponding to the eccentric protrusion 310; when the locking strip 3 is rotated relative to the plug-in base plate 2 by a first predetermined angle, the eccentric protrusion 310 enters the position-avoiding through-hole 230 and extends out of the end surface of the bottom wall of the plug-in base plate 2;

[0029] When the locking bar 3 is rotated relative to the plug-in base plate 2 by a second predetermined angle, the eccentric protrusion 310 is withdrawn from the avoidance through hole 230. Before inserting the first plug-in section 210 or the second plug-in section 220 connected to the locking bar 3 into the connecting groove 110, the locking bar 3 needs to be rotated relative to the plug-in base plate 2 by the second predetermined angle.

[0030] Working principle: When the first plug-in section 210 and the second plug-in section 220 are both provided with a receiving groove 215, the number of locking strips 3 is also two. The first plug-in section 210 of the plug-in base plate 2 is inserted into the connecting groove 110 of another profile 1 from the end opening 120, and the second plug-in section 220 of the plug-in base plate 2 is inserted into the connecting groove 110 of the other profile 1 from the end opening 120.

[0031] Due to the closing structure of the closing block 111 on the notch of the connecting groove 110 , the plug-in base plate 2 can only be disassembled and separated from the profile 1 in the opposite moving direction relative to the profile 1 when inserted into the connecting groove 110 .

[0032] When the locking strip 3 rotates relative to the plug-in base plate 2 by a first predetermined angle, the eccentric protrusion 310 enters the avoidance through-hole 230 and extends out of the bottom wall end surface of the plug-in base plate 2. The eccentric protrusion 310 abuts against the wall surface of the connecting groove 110, thereby achieving a fixed connection between the profile 1 and the quick-disconnect connector. Specifically, the eccentric protrusion 310 abuts against the wall surface of the connecting groove 110, exerting a pressing force on the profile 1, thereby generating limiting friction, which prevents the two from easily moving relative to each other. Depending on the elastic and plastic deformation capabilities of the different materials of the profile 1 and the different dimensional design parameters of the eccentric protrusion 310, the eccentric protrusion 310 can cause plastic deformation of the profile 1, resulting in a pit at the location where the profile 1 and the eccentric protrusion 310 abut, thereby achieving a concave-convex fit. Alternatively, after the eccentric protrusion 310 stops pressing on the surface of the profile 1, the profile 1 elastically returns to its original state.

[0033] When it is necessary to release the connection between the profile quick-disconnect connector and the profile 1, it is only necessary to rotate the locking strip 3 relative to the plug-in base plate 2 to a second predetermined angle, that is, when the eccentric protrusion 310 is withdrawn from the avoidance through hole 230, the locking strip 3 is rotated to an angle. After the eccentric protrusion 310 cancels the pressure on the surface of the profile 1, the plug-in base plate 2 can be freely plugged in and out relative to the connecting groove 110 to release the connection.

[0034] This connector can not only realize the quick connection between profiles 1, but also realize the quick disassembly and assembly. Moreover, the connection and alignment of profiles 1 are carried out simultaneously, which is more convenient and quicker than the existing technology of first aligning profiles 1 and then driving rivets or screws to connect.

[0035] The size of the plug-in base plate 2 and the size of the connecting groove 110 can be a transition fit relationship. When the length of the plug-in base plate 2 is long enough, the friction between the plug-in base plate 2 and the connecting groove 110 is high enough, and the pressing force of the eccentric protrusion 310 on the surface of the profile 1 is high enough, then this connection strength stability can be fully competent for profile frame structures that are temporarily built, used with low intensity, and require repeated disassembly and assembly.

[0036] Preferably, there is one locking strip 3 connected to the first plug-in section 210 , and the locking strip 3 is connected to an end of the first plug-in section 210 away from the second plug-in section 220 .

[0037] The width of the locking strip 3 is smaller than the opening enclosed by the two closing bars 111 of the notch of the connecting groove 110, so that the locking strip 3 can be easily rotated and switched between the first predetermined angle and the second predetermined angle.

[0038] Please refer to Figure 1 and Figure 3 The two ends of the plug-in base plate 2 are provided with sliding chamfers 240 .

[0039] The sliding chamfers 240 facilitate the guidance of both ends of the plug-in substrate 2 so as to be inserted into the connecting groove 110 .

[0040] Please refer to Figure 1 and Figure 2 、 Figure 4 , including a locking screw 4, and a screw connection hole 2151 is opened on the bottom wall of the accommodating groove 215.

[0041] Receiving slot 215 serves as a countersink for locking screw 4, accommodating the nut of locking screw 4 and saving space. After the quick-disconnect connector and profile 1 are connected, a preliminary alignment is achieved. Locking screw 4 is then inserted through screw connection hole 2151 to connect the connector and profile 1. This not only further enhances connection strength and stability, but also improves connection accuracy, avoiding the inconvenience and poor precision of manual alignment and screw tightening.

[0042] In addition, since the first plug-in section 210 and the second plug-in section 220 of the connector are inserted into the connection groove 110, the connector is prevented from being exposed to the outside, and the appearance is higher than connecting the side of the profile 1 with angle irons through screws or rivets.

[0043] Please refer to Figure 1 and Figure 3 A reference portion 216 is provided at the junction of the first plug-in section 210 and the second plug-in section 220.

[0044] In some embodiments, the reference portion 216 is a block-shaped structure, which can serve to indicate the depth limit of the first plug-in section 210 or the second plug-in section 220 inserted into the connecting groove 110 .

[0045] Please refer to Figure 1 and Figure 2 , including a rotating shaft 5 connected to the plug-in base plate 2, and the locking strip 3 is connected to the plug-in base plate 2 through the rotating shaft 5.

[0046] Preferably, when the locking strip 3 rotates relative to the plug-in base plate 2 by a first predetermined angle, the locking strip 3 is retracted into the plug-in base plate 2 .

[0047] Please refer to Figure 6 When the locking strip 3 rotates relative to the plug-in base plate 2 by a second predetermined angle, the locking strip 3 moves away from the end connected to the plug-in base plate 2 , and the end moves away from the receiving groove 215 .

[0048] Please refer to Figure 1 and Figure 2 , the first plug-in section 210 and the second plug-in section 220 are connected in a straight line;

[0049] This structure is suitable for the profiles 1 to be extended in the same straight line direction.

[0050] Or, please refer to Figure 4 and Figure 6 An angle corresponding to the relative connection position of the two profiles 1 is set between the first plug-in section 210 and the second plug-in section 220.

[0051] This structure is suitable for reversing connection of two profiles 1 in non-colinear directions.

[0052] Please refer to Figure 4 and Figure 6 , including a connecting block 6, which is connected to the plug-in base plate 2 and is used to connect at least two of the profile quick-disassembly connectors in parallel into one.

[0053] This design is suitable for connecting larger profiles 1 to profiles 1. Multiple profile quick disassembly connectors are connected in parallel as one, corresponding to the multiple connection grooves 110 on the profile 1, avoiding repeated installation operations of multiple split structures.

[0054] After assembly, it can form the side frames of electrical products such as outdoor advertising machines and light boxes. Before assembly, the profiles and profile quick-disconnect connectors are disassembled for easy packaging and transportation.

[0055] Please refer to Figure 4 and Figure 6 , including a fin plate 7 connected to the plug-in base plate 2 and / or the connecting block 6, the cross-sectional profile of the fin plate 7 at least corresponds to the profile of the outer area of ​​the cross-sectional area of ​​the profile 1.

[0056] The fin plate 7 is used to fill the gap in the outer area of ​​the profile 1 at the connection turning point when two profiles 1 are connected in a non-straight direction, thereby improving the aesthetics and structural strength.
