Description

[0003] The handles of these devices have batteries and control modules built into them, which are then connected to electrical equipment at the far end by wires to form a closed circuit. Due to the requirements for the effective distance, most of them have a long overall structure and can only be installed in a hollow long tube. They are also complex in structure and installation, and are inconvenient to carry.

[0004] At present, the common way to solve this problem is to design the straight pipe structure into an assembled, telescopic, or foldable type. The disadvantage of the assembled type is that it requires users to assemble it themselves, and it may not be as portable as other methods. The telescopic type is characterized by the use of a sliding connection method. The farthest end of the multi-section sliding will be smaller in diameter than the proximal end, which is not conducive to the design and installation of equipment. In addition, it is not as good as the foldable type in that it can significantly reduce the volume. The advantages of the foldable type are extreme portability, high flexibility, and no change in the diameter of the far and near ends, which is conducive to the design and installation of equipment. However, the foldable type in the prior art only solves the folding between pipeline structures, and lacks an effective connection method between the circuits from the handle to the electrical equipment.

[0029] The following is combined with Figure 1-Figure 1 0 and specific embodiments further introduce the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by ordinary technicians in the technical field to which the present invention belongs.

[0030] The present invention discloses a foldable multi-section pipe electrical connector structure, which is used for connecting (merging) and disconnecting (folding) wiring pipes 9, and can realize the transmission of strong and weak electrical signals when in the connected (merged) state. The electrical connector structure is fixedly installed at the ends of two wiring pipes 9 that need to be connected, and the electrical connector structure includes a piston seat 1, a piston stopper 2, a piston assembly, and an electrical signal transmission mechanism 4;

[0031] like Figure 1 As shown, the piston seat 1 and the piston stopper body 2 are hinged at the matching installation position through a hinge 6; specifically, one end of the hinge 6 is hinged to the hinge installation opening on the piston seat 1, and the other end of the hinge 6 is hinged to the hinge installation opening on the piston stopper body 2;

[0032] The piston seat 1 is a cylindrical structure with a through hole inside for installing the piston assembly; four through holes are evenly arranged around the center of the piston seat 1 for fixedly installing the push-and-plug type elastic transmission mechanism 4-1; a positioning pin hole is arranged on the cylindrical wall of the piston seat 1.

[0033] The piston stopper body 2 is a cylindrical structure, and its end (close to the end connected to the piston seat 1) is provided with a connecting hole that cooperates with the cone and cylinder on the piston 3, so that when the piston stopper body 2 and the piston seat 1 are combined, it cooperates with one end of the piston 3; four through holes are evenly arranged around the center for fixed installation of the push-and-plug type rigid transmission mechanism 4-2.

[0034] The self-adjusting limit block 5 is provided with a clamping protrusion and a top protrusion; one end of the self-adjusting limit block 5 is hinged on the self-adjusting limit block installation port of the piston seat 1, and the self-adjusting limit block 5 is provided with a countersunk hole in the direction close to the inner wall of the piston seat 1, and a second compression spring 5-1 is provided in the countersunk hole, one end of the second compression spring 5-1 contacts the end of the countersunk hole, and the other end contacts the inner wall of the self-adjusting limit block installation port of the piston seat 1. The piston 3 in the piston assembly is installed in the through hole of the piston seat 1, and the outer wall of the piston 3 contacts the self-adjusting limit block 5, and the self-adjusting limit block realizes axial limitation of the piston, and at this time, the second compression spring 5-1 is in an initial free state.

[0035] The piston assembly includes a piston 3, a first compression spring 3-1, a first pin 3-2 and a first limiting pin 3-3.

[0036] The piston 3 is a rotating body structure, including a cylindrical section and a frustum section, and a boss is formed at the connection between the cylindrical section and the frustum section. A step hole is provided inside the piston 3 for installing and limiting the first compression spring 3-1. A first pin hole is provided at the bottom of the piston 3 for installing the first pin 3-2, and a waist-shaped through hole is provided on the side wall of the piston 3 for installing the first limiting pin 3-3. Figure 7 As shown, on the boss formed by the cylindrical section and the frustum section of the piston 3, a first plane is processed at the root of the frustum section, which increases the contact area with the clamping protrusion of the self-adjusting limit block 5 and avoids interference with the self-adjusting limit block 5.

[0037] Specifically, the first compression spring 3-1 is installed in the piston 3, and one end of the first compression spring 3-1 contacts the internal step surface of the internal step hole of the piston 3 to limit one end of the first compression spring 3-1; the first limit pin 3-3 passes through the positioning pin hole on the piston seat 1 and the waist-shaped through hole set on the side wall of the piston 3, and contacts the other end of the first compression spring 3-1 to limit the other end of the first compression spring 3-1. The first pin 3-2 is installed in the first pin hole, which is used to connect the pull rope 10 and drive the piston 3 to move when the electrical connector needs to be disconnected. When the electrical connector is in the disconnected state, the first compression spring 3-1 is in a compressed state. When the piston 3 is at the maximum displacement near the bottom of the piston seat 1, the self-adjusting limit block 5 cooperates with the position on the piston 3 to limit the piston 3 axially. When the electrical connector needs to be connected (i.e., the wiring tubes 9 are merged), the piston block body 2 and the piston seat 1 are closed, and the card slot on the piston block body 2 acts on the top protrusion of the self-adjusting limit card block 5, so that the self-adjusting limit card block 5 rotates toward the inner wall of the self-adjusting limit card block installation port close to the piston seat 1, compressing the second compression spring 5-1, completing the unlocking of the step surface of the piston 3, and the piston 3 moves toward the piston block body 2 under the action of the restoring force of the first compression spring 3-1, and enters the connecting hole inside the piston block body 2, realizing the connection between the piston seat 1 and the piston block body 2. At this time, the raised elastic contact point on the push-insertion elastic transmission mechanism 4-1 contacts the concave contact point on the push-insertion rigid transmission mechanism 4-2, realizing the connection of the electrical signal.

[0038] A raised male buckle is provided at the end of the piston seat 1, and a recessed female buckle hole is provided on the end surface of the piston stopper body 2. When the piston seat 1 and the piston stopper body 2 are combined, the male buckle cooperates with the female buckle hole to further ensure the coaxiality of the piston seat 1 and the piston stopper body 2 when they are combined.

[0039] The push-insert type electrical signal transmission mechanism 4 (conduction mechanism) includes a push-insert type elastic transmission mechanism 4-1 and a push-insert type rigid transmission mechanism 4-2:

[0040] The push-and-plug elastic transmission mechanism 4-1 includes a first connection seat 4-1-1, an insulating tube 4-1-2 and a spring conductive needle 4-1-3.

[0041] Four insulating tubes 4-1-2 are evenly fixedly installed on the first connection seat 4-1-1 in the circumferential direction, and a spring conductive pin 4-1-3 is installed inside each insulating tube 4-1-2; the end of the spring conductive pin 4-1-3 is a convex contact point. The spring conductive pin 4-1-3 is close to the bottom of the first connection seat 4-1-1 and is connected to the socket through a wire.

[0042] The spring conductive needle 4-1-3 usually consists of three basic parts: the needle shaft, the spring, and the needle tube. The spring conductive needle is formed by riveting with precision instruments. The spring conductive needle 4-1-3 is widely used in various electronic products to play a role in signal transmission and connection.

[0043] The push-and-plug rigid transmission mechanism 4-2 includes a first connection seat 4-1-1, an insulating tube 4-1-2 and a first guide core 4-1-4; four insulating tubes 4-1-2 are evenly fixedly installed on the first connection seat 4-1-1 in the circumferential direction, and a first guide core 4-1-4 is installed inside each insulating tube 4-1-2. The end of the first guide core 4-1-4 is a concave contact point, which is used to cooperate with the end convex contact of the spring conductive needle 4-1-3 to transmit the electrical signal. The first guide core 4-1-4 is connected to the socket through a wire near the bottom of the first connection seat 4-1-1.

[0044] The electrical connector also includes a handle 7; the handle 7 is installed at one end of the wiring tube 9 away from the electrical connector, and the handle 7 includes a handle shaft 7-1, a handle shell 7-2, a handle sleeve 7-3, a handle spring 7-4, a rope tightener 7-5, a spring limit ring 7-6, a control unit and a second limit pin.

[0045] The handle sleeve 7-3 is fixedly connected to the end of the wiring tube 9, one end of the handle shaft 7-1 passes through the inner hole of the handle sleeve 7-3, is fixedly connected to the spring limit retaining ring 7-6, and extends into the wiring tube 9; the handle shell 7-2 is fixed on the shaft wall of the handle shaft 7-1 near the other end; a handle spring 7-4 is sleeved on the handle shaft 7-1 and between the spring limit retaining ring 7-6 and the handle sleeve 7-3, which is used for the movement and reset of the handle shaft 7-1. A waist-shaped hole is provided on the shaft wall of the handle shaft 7-1, and a second limit pin 7-9 is fixedly provided on the handle sleeve 7-3, and the second limit pin 7-9 passes through the waist-shaped hole on the handle shaft 7-1, thereby limiting the movement distance of the handle shaft 7-1 relative to the wiring tube 9.

[0046] A through hole is provided inside the handle shaft 7-1, and a rope tightener 7-5 is fixed to the end surface of the handle shaft 7-1 by a thread, and the rope tightener 7-5 is used to lock the pull rope. One end of the pull rope 10 is connected to the first pin 3-2 on the piston 3 in the electrical connector, and the other end passes through the wiring tube 9, the handle shaft 7-1 and the rope tightener 7-5 and comes out.

[0047] The control unit is arranged inside the handle shell 7-2 and does not interfere with the passing pull cord 10. One end of the connecting line 11 is connected to the control unit, and the other end is provided with a plug, which is connected to the socket on the first connecting seat 4-1-1; it is used to realize the conduction of electrical signals.

[0048] When the wiring tubes 9 need to change from a connected (merged) state to a disconnected (folded) state, the handle shell 7-2 is dragged outward, thereby driving the handle shaft 7-1 to move outward relative to the wiring tubes 9. The handle shaft 7-1 drives the piston 3 to move in the direction of the piston seat 1 through the pull rope 10, and the connection between the wiring tubes 9 is disconnected, and the piston seat 1 is separated from the piston block body 2, thereby realizing the disconnection of the contacts between the push-plug type elastic transmission mechanism 4-1 and the push-plug type rigid transmission mechanism 4-2 in the push-plug type electrical signal transmission mechanism 4.

[0049] like Fig. 9 As shown, as an embodiment of the present invention, two wiring tubes 9 are connected through an electrical connector. Specifically, the piston seat 1 and the piston stopper 2 are fixedly mounted on the ends of the two wiring tubes 9, respectively. The other end of one wiring tube 9 is provided with a handle 7, and the other end of the other wiring tube 9 is provided with a battery and an electronic and electrical equipment load 8. The battery and the electronic and electrical equipment load 8 are connected to one end of the connecting wire 11, and the other end of the connecting wire 11 is provided with a plug connected to the socket on the push-plug rigid transmission mechanism 4-2, so as to realize the connection between the battery and the electronic and electrical equipment load 8 and the connector.

[0050] As another embodiment of the present invention, the electrical connector can realize the connection between two or more wiring tubes 9. After the wiring tubes 9 are connected, the two wiring tubes 9 at the end, one wiring tube 9 is connected to the handle 7, and the other wiring tube 9 is connected to the battery and the electronic and electrical equipment load 8.

[0051] During installation, the folding direction of the wiring tube 9 when the connector is disconnected must be opposite. For example, when three wiring tubes 9 are connected through an electrical connector, they are folded into an "N" shape in the disconnected state.

[0052] Among them, the insulating tube 4-1-2 is an insulating material, and various plastics such as ABS engineering plastics, PVC, and nylon can be selected.

[0053] The working principle of the foldable multi-section tube electrical connector structure is as follows: when two or more wiring tubes 9 are connected, the piston seat 1 and the piston stopper 2 are fixedly mounted on the ends of the two wiring tubes 9, respectively, one of the wiring tubes 9 is provided with a handle 7 at the other end, and the other end of the other wiring tube 9 is connected to the battery and the electronic and electrical equipment load 8. The plugs on the battery and the electronic and electrical equipment load 8 are connected to the sockets on the push-insertion rigid transmission mechanism 4-2 through the connecting wire 11, so as to realize the connection between the battery and the electronic and electrical equipment load 8 and the connector. The handle shaft 7-7 is connected to the socket on the push-insertion elastic transmission mechanism 4-1 through the connecting wire 11, so as to realize the connection between the handle and the connector.

[0054] When the two wiring tubes 9 are connected (merged), the piston 3 moves to the connection hole in the piston stopper 2; at this time, the contact points of the push-insertion elastic transmission mechanism 4-1 and the push-insertion rigid transmission mechanism 4-2 are connected. When the wiring tube 9 needs to enter the disconnected (folded) state, the handle shell 7-2 is dragged outward, thereby driving the handle shaft 7-1 to move outward relative to the wiring tube 9, compressing the handle spring 7-4, and the handle shaft 7-1 drives the piston 3 to move in the direction of the piston seat 1 through the pull rope 10, thereby compressing the first compression spring 3-1 inside the piston 3, so that the connection between the wiring tubes 9 is disconnected, the piston seat 1 and the piston stopper 2 are separated, and the contact points between the push-insertion elastic transmission mechanism 4-1 and the push-insertion rigid transmission mechanism 4-2 in the push-insertion electrical transmission mechanism 4 are disconnected; the piston 3 moves to the maximum displacement inside the piston seat 1 and is limited and clamped by the clamping protrusion on the self-adjusting limit clamp 5.

[0055] When the wiring tube 9 needs to enter the connected (merged) state from the disconnected (folded) state, the piston seat 1 and the piston block body 2 are merged, and the card groove on the piston block body 2 acts on the top of the self-adjusting limit block 5, so that the self-adjusting limit block 5 rotates, completing the unlocking of the top of the piston 3, and the piston 3 moves toward the piston block body 2 under the action of the restoring force of the first compression spring 3-1, and enters the connecting hole inside the piston block body 2, realizing the connection between the piston seat 1 and the piston block body 2, and at this time, the raised elastic contact point on the push-plug type elastic transmission mechanism 4-1 contacts the concave contact point on the push-plug type rigid transmission mechanism 4-2, realizing the connection of the signal.

[0056] The multi-section wiring tube 9 can be installed with various electrical equipment loads, batteries and control units according to the actual diameter of the tube, and then connected mechanically and electronically by the electrical connector. This achieves the straight tube type integrated operation effect and the foldable portability effect. The wiring tube 9 can be made of various engineering plastic tubes, metal material tubes, carbon fiber tubes, glass fiber tubes, etc.
