Description

[Technical Field]

[0001] The present invention relates to the technical field of folding rods, and more particularly to a rotary connecting joint and folding rod group with a stopper control device. [Background technology]

[0002] The folding rod group is the core support structure of folding furniture (e.g., folding chairs, folding beds) and portable devices, and its core is to realize the deployment and fixing of rod members and the folding and storage through the rotation-lockable hinge connection points of the connecting joints.

[0003] Conventional folding rod groups (such as folding chair holders) always use plug-type or knob-type locking joints, which have obvious drawbacks: (1) Complicated operation: Unlocking requires two-handed operation (pulling out the plug, turning the nut, etc.), making it impossible to quickly fold with one hand; (2) Unreliable: The plug is prone to unexpectedly coming out and causing the lock to malfunction, and the knob is prone to loosening due to vibration; (3) Exposed structure: The locking components are exposed to the outside and are prone to contamination and mechanical damage; (4) Large space occupancy: An external locking mechanism increases the joint volume, affecting the compactness of the folding mechanism.

[0004] Therefore, a technical solution that can solve the above problems is needed. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION In order to solve the technical problems existing in the prior art, the object of the present invention is to provide a rotary connecting joint and a folding rod group equipped with a stopper control device that can solve the above technical problems. [Means for solving the problem]

[0008] Preferably, the first connecting member and the second connecting member are both provided with mounting grooves, and when the first connecting member and the second connecting member are connected to each other, the position of the mounting groove of the first connecting member corresponds to the position of the mounting groove of the second connecting member, and the locking member has a protrusion that can slide in the mounting grooves of the first connecting member and the second connecting member, When the locking member is in the locked position, the entire protrusion is located within the mounting groove of one of the first connecting member and the second connecting member; When the locking member is in the unlocked position, the protrusion is located between the mounting groove of the first connecting member and the mounting groove of the second connecting member.

[0009] Preferably, one of the first connecting member and the second connecting member is provided with a regulating plate having a through hole, and the other is provided with a pillar having a through hole, and the first connecting member and the second connecting member are connected to the through hole of the regulating plate via a bolt that passes through the pillar.

[0010] Preferably, the locking member is provided with a retraction hole, and when the locking member is attached to the lock chamber, the locking member is fitted to the outside of the pillar through the retraction hole.

[0011] Preferably, the second portion of the pressing member is a cap portion exposed to the outside of the pressing chamber, and the first portion is a pressing foot that enters the lock chamber and abuts against the lock member.

[0012] Preferably, the distal end of the pressing foot is provided with a restricting protrusion for preventing the pressing member from escaping from within the lock chamber.

[0013] Preferably, two pressure feet are provided, and when the pressure feet enter the lock chamber, the regulating plate is positioned between the two pressure feet to prevent relative movement of the two pressure feet.

[0017] In this device, a locking chamber is provided between the connecting members, and an elastic member, a locking member, and a pressing member are provided within the locking chamber. When the pressing member presses, the locking member overcomes the elastic force of the elastic member, causing it to leave the locked position, thereby realizing instantaneous unlocking and free rotation of the rod group. This simplifies operation, allows for quick one-handed folding, and improves efficiency.

[0018] In this invention, the locking member is installed inside the locking chamber, and both locking and unlocking are performed inside the locking chamber, which is highly reliable and avoids problems such as lock failure due to accidental release and loosening of the knob due to vibration.

[0019] The locking member of the present invention is subjected to the elastic force of the elastic member within the locking chamber, and after the pressing member is released, the elastic member automatically presses the locking member into the locked position, thereby ensuring rigid locking of the rod group in the deployed state and significantly enhancing the ability to resist vibration and falling off. In addition, the locking member and the elastic member are located within the locking chamber, reducing the exposed parts, reducing the joint volume, and making the device more compact when folded.

[0026] FIG. 1 is a structural schematic diagram of a folding rod group of a rotary joint equipped with a stopper control device according to the present invention.

[0027] As shown in Figures 1 to 18, the folding rod group of the rotary connection joint with a stopper control device includes a rotary connection joint 100 with a stopper control device and rod members 200. The rod members 200 are connected to the rotary connection joint 100 with a stopper control device, and are connected via the rotary connection joint 100 with a stopper control device, so that the rod members 200 can be rotated relative to each other, and the rod members 200 can be locked together via the rotary connection joint 100 with a stopper control device, allowing the rod members 200 to be operated to fold and unfold, etc.

[0028] 1, 2 and 3, a rotary connection joint 100 equipped with a stopper control device includes a first connection member 110, a second connection member 120, a locking member 130, a pressing member 140 and an elastic member 150.

[0029] 4 to 14, the first connecting member 110 and the second connecting member 120 are rotatably connected, and each is provided with a joint 111 for connection to the rod member 200.

[0030] Specifically, in this embodiment, the first connecting member 110 and the second connecting member 120 each have one end configured as a circular structure 112, and a joint 111 extending from the other end, the shape of which matches the shape of the rod member 200. When connecting the first connecting member 110 and the second connecting member 120, the ends of the circular structures 112 are arranged coaxially and connected via a bolt. The bolt does not lock the first connecting member 110 and the second connecting member 120, and the first connecting member 110 and the second connecting member 120 can still rotate relative to each other, so that the rod member 200 connected between the first connecting member 110 and the second connecting member 120 can be folded or unfolded relative to each other, i.e., the first connecting member 110 and the second connecting member 120 are hingedly connected.

[0031] Preferably, one of the first connecting member 110 and the second connecting member 120 is provided with a pillar 113, and the other is provided with a restricting plate 121, and both the pillar 113 and the restricting plate 121 are provided with a through hole 114. When connecting the first connecting member 110 and the second connecting member 120, the through hole 114 in the pillar 113 is aligned with the through hole 114 in the restricting plate 121, and a bolt is inserted into the pillar 113 from the outside of the first connecting member 110 or the second connecting member 120, passes through the through hole 114 in the restricting plate 121, and is screwed into a nut, thereby connecting the first connecting member 110 and the second connecting member 120 to each other. Specifically, in this embodiment, the first connecting member 110 is provided with the pillar 113, and the second connecting member 120 is provided with the restricting plate 121.

[0032] Preferably, when the first connecting member 110 and the second connecting member 120 are connected, they are both provided with a hinged reinforcement plate 160, one end of which is connected to the joint 111 of the first connecting member 110 or the second connecting member 120, and the other end is connected to the connection point between the first connecting member 110 and the second connecting member 120. Specifically, referring to Figures 2 and 12, two hinged reinforcement plates 160 are provided, each with one end connected to the joint 111 of the first connecting member 110 and the second connecting member 120 and the other end connected to the end of the circular structure 112 of the first connecting member 110 and the second connecting member 120, thereby strengthening the connection between the first connecting member 110 and the second connecting member 120. The hinge connection reinforcement plate 160 is rotatably connected to the connection point between the first connecting member 110 and the second connecting member 120 so as not to affect the relative rotation of the first connecting member 110 and the second connecting member 120. The hinge connection reinforcement plate 160 reinforces the hinge connection between the first connecting member 110 and the second connecting member 120, thereby preventing separation between the first connecting member 110 and the second connecting member 120.

[0033] When the first connecting member 110 and the second connecting member 120 are connected to each other, a lock chamber 100a is formed, and the elastic member 150 and the lock member 130 are installed in the lock chamber 100a at the connection point between the first connecting member 110 and the second connecting member 120. The lock member 130 has a locked position and an unlocked position within the lock chamber 100a and is movable between the locked position and the unlocked position to lock or unlock the first connecting member 110 and the second connecting member 120 and allow the rod member 200 connected between the first connecting member 110 and the second connecting member 120 to rotate relative to each other. The elastic member 150 is installed within the lock chamber 100a and abuts against the lock member 130, generating an elastic force in the lock member 130 to maintain the lock member 130 in the locked position. Preferably, the elastic member 150 is fitted to the pillar 113.

[0034] 14 and 18, one of the first connecting member 110 and the second connecting member 120 is further provided with a pressing chamber 100b, and a pressing member 140 is mounted in the pressing chamber 100b and includes a first portion and a second portion, the first portion of the pressing member 140 abutting against the locking member 130 within the locking chamber 100a, and the second portion of the pressing member 140 is exposed from one of the first connecting member 110 and the second connecting member 120 and is used for external pressing. When pressed, the pressing member 140 abuts against the locking member 130, thereby causing the locking member 130 to overcome the elastic force of the elastic member 150 and move from the locked position to the unlocked position, allowing the first connecting member 110 and the second connecting member 120 to rotate relative to each other. When the pressing member 140 is released, the locking member 130 moves from the unlocked position to the locked position under the action of the elastic force of the elastic member 150, thereby locking the first connecting member 110 and the second connecting member 120 together and preventing them from rotating relative to each other.

[0035] Specifically, in this embodiment, the first connecting member 110 and the second connecting member 120 each have a mounting groove 115 at the end of the circular structure 112. When the first connecting member 110 and the second connecting member 120 are connected to each other, the mounting groove 115 of the first connecting member 110 and the mounting groove 115 of the second connecting member 120 correspond and fit together to form a lock chamber 100a for accommodating the lock member 130. The lock member 130 has a shape that matches the mounting groove 115 and has a protrusion 133. The protrusion 133 may be mounted in the mounting groove 115 and be movable within the mounting groove 115, thereby allowing the lock member 130 to move within the lock chamber 100a. Furthermore, within the lock chamber 100a, when the entire protrusion 133 of the locking member 130 is located within the mounting groove 115 of one of the first connecting member 110 or the second connecting member 120, the locking member 130 is in the unlocked position (unlocked state), whereas when a part of the locking member 130 is located within the mounting groove 115 of the first connecting member 110 and another part of the locking member 130 is located within the mounting groove 115 of the second connecting member 120, i.e., when the protrusion 133 is located between the mounting groove 115 of the first connecting member 110 and the mounting groove 115 of the second connecting member 120, the locking member 130 is in the locked position (locked state), and the first connecting member 110 and the second connecting member 120 are prevented from rotating relative to each other by the locking member 130, and the first connecting member 110 and the second connecting member 120 are locked.

[0036] Preferably, the elastic member 150 is a spring, and a spring groove 131 is provided on one side of the locking member 130. When the locking member 130 and the elastic member 150 are both attached to the locking chamber 100a, the locking member 130 is fitted onto one end of the elastic member 150 via the spring groove 131, and the other end of the elastic member 150 abuts against the side wall of the locking chamber 100a (the bottom of the attachment groove 115 of the first connecting member 110 or the second connecting member 120), thereby allowing the elastic member 150 to generate an elastic force acting on the locking member 130. Specifically, in this embodiment, the elastic member 150 is provided within the first connecting member 110.

[0037] Preferably, the pressing member 140 has a circular cap structure, the second part of which is a cap portion 141 extending from the lock chamber 100a, and the first part of which is two pressing feet 142 provided below the cap portion 141. When installed, the pressing member 140 enters the lock chamber 100a and abuts against the lock member 130 to press the lock member 130.

[0038] 10 and 11, the pressing member 140 preferably further includes a restricting protrusion 1421 for restricting the pressing member 140 from escaping from the lock chamber 100a. Specifically, in this embodiment, the restricting protrusion 1421 is provided on the pressing foot 142, and each of the two pressing feet 142 is provided with a restricting protrusion 1421, the size of the two restricting protrusions 1421 being larger than the size of the mounting hole. When the two pressing feet 142 are mounted, they can be pressed to move relative to each other, reducing the distance between the two restricting protrusions 1421 and allowing the pressing feet 142 to be mounted within the lock chamber 100a through the mounting hole. When not pressed, the distance between the two pressing feet 142 is restored, and the distance between the restricting protrusions 1421 is larger than the size of the mounting hole, thereby restricting the pressing feet 142 and preventing them from escaping.

[0039] Preferably, at least a portion of the pressing member 140 extends from one of the first connecting member 110 and the second connecting member 120 where the regulating plate 121 is provided, and the width of the regulating plate 121 is slightly smaller than the width between the two pressing feet 142, and when the pressing feet 142 are inserted into the lock chamber 100a, they are located on either side of the regulating plate 121, respectively. Due to the action of the regulating plate 121, it is difficult for the two pressing feet 142 inserted into the lock chamber 100a to move relative to each other, and as a result, the regulating protrusion 1421 can always regulating the pressing feet 142 within the lock chamber 100a.

[0040] 13 and 14, when the pressing member 140 is pressed, the locking member 130 can overcome the elastic force of the elastic member 150, and the entire locking member 130 is positioned within the first connecting member 110 or the second connecting member 120, and the first connecting member 110 and the second connecting member 120 are unlocked and can rotate relative to each other. Referring to FIGS. 15 to 18, when the pressing member 140 is not pressed, under the action of the elastic member 150, a portion of the locking member 130 is positioned within the mounting groove 115 of the first connecting member 110 and another portion of the locking member 130 is positioned within the mounting groove 115 of the second connecting member 120, and the locking member 130 is in the locked position, and the first connecting member 110 and the second connecting member 120 are locked.

[0041] Preferably, the locking member 130 is further provided with a retraction hole 132 for retracting the pillar 113, and when the locking member 130 is attached to the lock chamber 100a, the pillar 113 passes through the retraction hole 132, and the locking member 130 can also rotate around the pillar 113.

[0042] The rod member 200 is a straight rod or an irregular rod, with a first fixing hole at one end and a second fixing hole at the joint 111 between the first connecting member 110 and the second connecting member 120. After the rod member 200 is connected into the joint 111 of the first connecting member 110 or the second connecting member 120, it can be fixed into the first fixing hole and the second fixing hole via a bolt, thereby fixing the rod member 200 to the first connecting member 110 or the second connecting member 120.

[0043] In use, the folding rod group of the rotary connection joint 100 equipped with the stopper control device can be used in a folding chair, and the rod group serves as a support frame for the folding chair. When the folding chair needs to be unfolded, the rod member 200 connected to the first connecting member 110 and the second connecting member 120 is unfolded 180 degrees. At this time, the locking member 130 is in the locked position within the lock chamber 100a. When the folding chair needs to be folded, the pressing member 140 is pressed, and the pressing member 140 presses the locking member 130 to the unlocked position within the lock chamber 100a, and the rod members 200 connected to the first connecting member 110 and the second connecting member 120 can rotate relative to each other. At this time, the mounting groove 115 of the first connecting member 110 and the mounting groove 115 of the second connecting member 120 do not correspond to each other, and the locking member 130 overcomes the elastic force of the elastic member 150 due to the pressure of the pressing member 140 and falls into the mounting groove 115 of one of the first connecting member 110 and the second connecting member 120, allowing the rod members 200 of the first connecting member 110 and the second connecting member 120 to rotate freely, thereby folding the folding chair.

[0044] As can be understood, multiple sets of folding bars of the rotary connection joint 100 equipped with the stopper control device may be provided in the folding chair as required.

[0045] The above are only some embodiments of the present invention, and those skilled in the art may make some modifications and improvements within the scope of protection of the present invention without departing from the creative concept of the present invention. [Explanation of symbols]
