The upper left side of the connecting front fork 3 is also provided with a pushing part 32 which is positioned at the upper left side of the limiting groove 31 and is used for pushing the limiting bolt 2. The pushing portion 32 is arc-shaped, and is aimed at smoothly pushing the limit plug 2, so as to avoid interference. The right side of the pushing part 32 is provided with a downward concave penetrating lower groove 33 penetrating the front connecting fork 3. The upper side of the front connecting fork 3 is also provided with a yielding groove 34 which transversely penetrates through the lower penetrating groove 33 and is used for yielding the lower end of the frame connecting seat 1 to extend into the frame connecting seat. The front side and the rear side of the frame connecting seat 1 are respectively provided with a positioning protrusion 12 protruding outwards and being matched with the through lower groove 33 and used for positioning and connecting the front fork 3. The positioning protrusion 12 is attached to the through lower groove 33, so that the front connection fork 3 and the frame connecting seat 1 are connected in place, and the front connection fork 3 and the frame connecting seat 1 are positioned and connected in a convenient manner.
The tightening assembly 4 comprises a connecting mounting body 41, an elastic block 42, a connecting pull rod 43, an elastic resetting piece 44, a guide part 45, a connecting crank 46, a connecting lug 47 and a tightening wrench 48. The connection mounting body 41 is arranged at the lower side of the inner part of the frame connecting seat 1 along the transverse direction of the frame connecting seat 1, and is provided with a mounting notch 411 with an opening facing the left side. The elastic block 42 is disposed in the mounting slot 411, and its left end extends out of the left side of the mounting slot 411. The connecting pull rod 43 is disposed between the elastic block 42 and the limiting latch 2, and the left end of the connecting pull rod penetrates through the right side wall of the through hole 11 and then is connected with the right side of the limiting latch 2. The elastic resetting piece 44 is sleeved on the connecting pull rod 43 and is positioned in the frame connecting seat 1. The guide member 45 transversely penetrates through the left side wall of the through hole 11 and is sleeved on the left side of the frame connecting seat 1, and the right end of the guide member is connected with the left side of the limiting bolt 2. The left lower end of the connecting crank 46 is hinged with the right end of the connecting pull rod 43. The connecting projection 47 is located at the upper side of the connecting mounting body 41, and its upper end is hinged to the upper right end of the connecting crank 46, and its lower end is in an outer convex arc shape. The elastic wrench 48 is hinged to the frame connecting seat 1 along the longitudinal direction of the frame connecting seat 1, and is connected to the lower end of the connecting bump 47, and the front end of the elastic wrench is located at the front side of the frame connecting seat 1. The elastic block 42 is a rubber elastic pad, the elastic restoring member 44 is a tower-shaped compression spring, and the elastic force of the elastic restoring member is smaller than that of the elastic block 42.
When the connecting fork 3 is in a folded state, the elastic component 4 is in a semi-elastic state as a whole, wherein the elastic reset piece 44 pulls the connecting pull rod 43 to link the limiting bolt 2 and the guiding component 45 to move rightwards along the transverse direction of the frame connecting seat 1 until the connecting pull rod 43 is blocked by the elastic block 42, and the elastic action of the elastic reset piece 44 is smaller than that of the elastic block 42, so that the connecting pull rod 43 is blocked by the elastic block 42 to stop moving rightwards, and at the moment, the limiting bolt 2 is just positioned in the middle of the through hole 11, so that the pushing part 32 is convenient to contact and push the limiting bolt 2 when the connecting fork 3 is unfolded;
further, when the front connecting fork 3 is lowered and unfolded from the folded state, the wheels 5 connected with the front connecting fork 3 in a linkage manner rotate clockwise around the hinge joint of the front connecting fork 3 and the frame connecting seat 1 under the action of gravity, and due to the inertia effect, the pushing part 32 on the front connecting fork 3 firstly contacts the limit bolt 2 and overcomes the elastic force of the elastic reset piece 44, and then pushes the limit bolt 2 leftwards, in the process, the connecting pull rod 43 moves leftwards from the limit bolt 2 and compresses the elastic reset piece 44, and the guide part 45 also moves leftwards from the limit bolt 2;
when the limiting plug 2 is pushed to the left side of the through hole 11, the pushing part 32 rotates to the upper side of the limiting plug 2, the elastic reset piece 44 elastically resets to act on the connecting pull rod 43 to drive the limiting plug 2 to link the guiding part 45 to move rightwards, and when the limiting plug 2 moves to the middle of the through hole 11, the front end and the rear end of the limiting plug 2 are clamped into the limiting groove 31 positioned on the connecting front fork 3, so that the purpose of primarily locking the connecting front fork 3 is achieved;
in the above process, the connecting crank 46, the connecting lug 47 and the elastic wrench 48 are driven to reciprocate by the connecting rod 43;
although the front fork 3 and the wheel 5 can be initially locked on the frame connecting seat 1 by gravity and inertia when being unfolded by lowering, if external force (such as vibration) is applied to cause the limit plug 2 to move leftwards, the left side of the front fork 3 is easy to drop off the frame connecting seat 1 to cause potential safety hazard, so that the elastic wrench 48 needs to be pulled to rotate clockwise, so that the elastic wrench 48 drives the connecting lug 47 to swing leftwards and rightwards around the longitudinal direction thereof, then the right upper end of the connecting crank 46 moves from the connecting lug 47, the lower end drives the connecting pull rod 43 to link the limit plug 2 and the guide member 45 to move rightwards (the movement amplitude is smaller) under the condition of overcoming the elastic resistance of the elastic block 42, the elastic block 42 is pushed to recover leftwards after being compressed, the elastic block 42 is pushed to restore leftwards, the elastic rod 43 is pushed to rotate leftwards, and the elastic wrench is locked, and the whole connecting assembly is locked when the elastic rod is pushed leftwards and the elastic rod is pushed to move forwards, and the elastic wrench is locked, and the connecting assembly is locked and the locking assembly is locked.
When the front fork 3 and the wheel 5 need to be loosened and folded, the elastic wrench 48 is pulled anticlockwise, the elastic wrench 48 drives the connection lug 47 to swing from right to left around the longitudinal direction of the connection lug, then the right upper end of the connection crank 46 moves from the connection lug 47, the lower end of the connection crank drives the connection pull rod 43 to link the limit bolt 2 and the guide part 45 to move leftwards until the front end and the rear end of the limit bolt 2 are withdrawn from the limit groove 31, then the left side of the front fork 3 is connected to drop off the frame connecting seat 1, and under the action of external force of an operator, the front fork 3 can drive the wheel 5 to rotate anticlockwise around the hinged position of the wheel to the right side of the frame connecting seat 1, so that folding work is completed.
The elastic wrench 48 includes a straight body portion 481 penetrating the frame connecting base 1 in the front-rear direction, and a pulling portion 482 connected to the straight body portion 481 and located at the front side of the frame connecting base 1 for pulling. The straight body 481 has a cylindrical shape, and has a first straight surface 4811 and a second straight surface 4812 provided symmetrically with respect to the first straight surface 4811 on a peripheral side thereof in an axial direction. The use of the first straight surface 4811 and the second straight surface 4812 can ensure that the elastic wrench 48 is rigidly connected to the connection protrusion 47, so as to ensure that the connection protrusion 47 is synchronously driven by the elastic wrench 48.
The left end of the connecting pull rod 43 is smaller than the right end of the connecting pull rod 43, an inward concave yielding connecting groove 431 is formed in the right end of the connecting pull rod 43 and used for yielding the left lower end of the connecting crank 46 to extend into the connecting groove 431, and the yielding connecting groove 431 comprises an upward opening with an upward opening, and a rightward opening with a rightward opening and a rightward opening communicated with the upward opening. The purpose is to increase the opening width of the yielding connection groove 431, so as to meet the requirement of large rotation of the connection crank 46.
The left side of the elastic block 42 is provided with a guiding protrusion 421 protruding leftwards and extending into the rightwards opening to guide the connecting pull rod 43 to be matched with the elastic block 42. This has the advantage of facilitating guiding the connecting rod 43 to connect with the resilient block 42.
The connecting crank 46 is "C" shaped. The purpose of this is to ensure that when the wrench 48 rotates clockwise past the dead point and is in a locked state, the connecting crank 46 just touches the straight body 481, thereby preventing the wrench 48 from continuing to rotate, and achieving the purpose of firmly locking the connecting front fork 3.
