Description

Technical Field

[0001] The invention relates to a folding device, in particular to a foldable connector between tent supports. Background Art

[0002] Traditional folding tents have many steps to fold and are inconvenient to store. For example, the bracket folding structure with application number 201822113746.x discloses a set seat, which forms at least one through-hole and an activity space connected to the through-hole, and defines a supporting surface in the activity space; a movable rod, which is arranged in the activity space and can be contacted and positioned with the supporting surface, and the movable rod defines a long hole structure corresponding to the through-hole; and a fixing member, which penetrates the through-hole and the long hole structure, and the movable rod can move the seat and rotate through the fixing member as an axis. When the seat is closed, that is, after the tent is unfolded and fixed, if it is to be stored and folded, it is necessary to pull the movable rod so that it and the seat are displaced in the axial direction of the seat; this requires holding the seat with one hand and pulling out the movable rod with the other hand, which often brings inconvenience to users who are prone to mechanical interference or hand slip in outdoor operation environments. Utility Model Content

[0003] The present invention aims to provide a bidirectional rotating clutch folding device which can overcome the above defects of conventional similar products and can ignore the user's hand slipping or mechanical interference and realize hand-carrying closure and hand-pushing folding.

[0004] Technical Solution

[0005] The present invention provides a two-way rotating clutch folding device, the folding device comprises a mother bearing connection member and a child bearing connection member; a closing rotating mechanism and a folding rotating mechanism are arranged between the mother bearing connection member and the child bearing connection member; a switching mechanism is arranged between the closing rotating mechanism and the folding rotating mechanism, and the switching mechanism enables the folding device to have at least two states:

[0006] Closed state: the male and female bearing connectors can and can only be released from the closed state through the closed rotation mechanism;

[0007] Folding state: the sub-connecting part and the mother-connecting part can rotate relative to each other through the folding and rotating mechanism;

[0008] An anti-reversal mechanism is provided between the mother bearing connection piece and the child bearing connection piece, and there is at least one direction or turn through which the child bearing connection piece and the mother bearing connection piece cannot leave the closed state.

[0009] The closing and rotating mechanism is provided with a limiting protrusion and a limiting guide rail; one of the limiting protrusion and the limiting guide rail is arranged on the sub-bearing connecting member, and the other is arranged on the mother-bearing connecting member; the limiting protrusion slides along the limiting guide rail to realize the closing or disengagement of the sub-bearing connecting member and the mother-bearing connecting member.

[0010] The closed rotating mechanism is provided with an anti-slip component and a closing through hole; one of the anti-slip component and the closing through hole is arranged on the sub-bearing connecting member, and the other component is arranged on the mother-bearing connecting member; the anti-slip component extends into or passes through the closing through hole, so that the mother-bearing connecting member and the sub-bearing connecting member can rotate or slide relative to each other, thereby closing or disengaging the sub-bearing connecting member and the mother-bearing connecting member.

[0011] The anti-reversal mechanism is provided with a concave contact surface on the limiting guide rail, and the limiting protrusion slides and / or rolls along the concave contact surface of the limiting guide rail; the anti-reversal mechanism is provided with a sleeve groove on the mother bearing connector, and the sub-bearing connector extends into the sleeve groove; the closing rotation mechanism and the folding rotation mechanism are both arranged on the contact surface of the mother bearing connector and the sub-bearing connector in the sleeve groove; the limiting guide rail is arranged at a position of the sleeve groove close to the notch, and the projection space of the concave opening of the concave contact surface of the limiting guide rail is within the projection space of the notch of the sleeve groove. When the sub-bearing connector extends into and abuts against the bottom of the sleeve groove, the mother bearing connector and the sub-bearing connector cannot rotate relative to each other in the direction of the notch.

[0012] The closed rotating mechanism is provided with a directional disengagement mechanism, which is arranged in the sleeve groove. The directional disengagement mechanism includes a buckle hook and a buckle groove. The buckle groove wall restricts the buckle hook from moving in the opposite direction of the sub-support connecting member extending into the sleeve groove.

[0013] The folding and rotating mechanism comprises a folding through hole, the folding through hole is connected with one end of the closing through hole, and the anti-dropping part slides in the space formed by the folding through hole and the closing through hole.

[0014] The folding through hole and the closing through hole are both long holes, and the angle opening direction formed by the folding through hole and the closing through hole is opposite to the direction in which the sub-support connecting piece extends into the sleeve groove.

[0015] A tent using the above-mentioned folding device, the tent comprising a tarpaulin, more than three pairs of support rods and a folding device, the support rods comprising upper support rods and lower support rods that are stretched outward with the tent, one of the sub-support connector and the mother-support connector of the folding device is connected to the upper support rod, and the other is connected to the lower support rod; the tangent of the closing point of the trajectory of the sub-support connector and the mother-support connector to complete the closing is parallel to the tangent of the upper support rod and the lower support rod at the closing point, or the angle formed is less than 90 degrees, so that when the tent is opened, the tension of the tarpaulin can squeeze the sub-support connector and the mother-support connector to have a closing tendency.

[0016] The folding direction of the upper support rod and the lower support rod is the same as the direction in which the folding device is disengaged from the closed state. When the external force acts in the folding direction and overcomes the force of the tarpaulin on the support rod, the folding device is disengaged from the closed state, the tarpaulin loses the force on the support rod, and the tent is folded. It is particularly pointed out that when the support rod pushes the tent outward, the hand acts in the direction of overcoming the pushing direction, that is, in the reverse direction.

[0017] The above technical solution is beneficial in that:

[0018] In the present invention, a closing rotation mechanism and a folding rotation mechanism are provided between the mother supporting connecting member and the child supporting connecting member; a switching mechanism is provided between the closing rotation mechanism and the folding rotation mechanism, that is, the closing and folding trajectories can be not completely overlapped, so that the force for completing the closing and the force for completing the folding are not on the same straight line, which makes it easy to design a technical solution to overcome the problem of easy opening (closing) and difficult folding. At the same time, it is convenient to store and install, and is more stable and has fewer faults.

[0019] An anti-reversal mechanism is provided between the mother supporting connector and the child supporting connector of the present invention, and the anti-reversal mechanism has the same anti-rotation direction as the movement trend of the support rod under the action of the tarpaulin. Therefore, when the folding device of the present invention is used for devices or objects with more than two states, such as tents, it has the effect of improving the state stability.

[0027] like Figure 1-Figure 5A bidirectional rotating clutch folding device is shown, the folding device comprises a mother bearing connection member 1 and a child bearing connection member 2; a closing rotating mechanism 3 and a folding rotating mechanism 4 are arranged between the mother bearing connection member 1 and the child bearing connection member 2; a switching mechanism 5 is arranged between the closing rotating mechanism 3 and the folding rotating mechanism 4, and the switching mechanism 5 enables the folding device to have at least two states:

[0028] Closed state: the male connector 2 and the female connector 1 can and can only be released from the closed state through the closed rotation mechanism 3;

[0029] Folding state: the sub-connecting member 2 and the female connecting member 1 can rotate relative to each other through the folding and rotating mechanism 4;

[0030] An anti-reversal mechanism 6 is provided between the female bearing connector 1 and the male bearing connector 2, and there is at least one direction or turn through which the male bearing connector 2 and the female bearing connector 1 cannot leave the closed state.

[0031] The closing rotation mechanism 3 is provided with a limiting protrusion 31 and a limiting guide rail 32; the limiting protrusion 31 is provided on the sub-bearing connecting member 2, and the limiting guide rail 32 is provided on the mother-bearing connecting member 1; the limiting protrusion 31 slides along the limiting guide rail 32 to realize the closing or disengagement of the sub-bearing connecting member 2 and the mother-bearing connecting member 1.

[0032] The closed rotating mechanism 3 is provided with an anti-slipping member 33 and a closing through hole 34; one of the anti-slipping member 33 and the closing through hole 34 is arranged on the sub-supporting member 2, and the other is arranged on the mother-supporting connecting member 1, and the anti-slipping member 33 extends into or passes through the closing through hole 34, so that relative rotation or sliding can occur between the mother-supporting connecting member 1 and the sub-supporting connecting member 2, thereby closing or disengaging the sub-supporting connecting member 2 and the mother-supporting connecting member 1.

[0033] The anti-reversal mechanism 6 is provided with a concave contact surface 61 on the limiting guide rail 32, and the limiting protrusion 31 slides and / or rolls along the concave contact surface 61 of the limiting guide rail; the anti-reversal mechanism 6 is provided with a sleeve groove 62 on the mother bearing connector, and the sub-bearing connector 2 extends into the sleeve groove 62; the closing rotation mechanism 3 and the folding rotation mechanism 4 are both arranged on the contact surface of the mother bearing connector 1 and the sub-bearing connector 2 in the sleeve groove 62; the limiting guide rail 32 is arranged at a position close to the notch of the sleeve groove 62, and there is at least a circular arc segment of the projection space S1 of the concave opening of the limiting guide rail concave contact surface 61 in the projection space S2 of the notch of the sleeve groove 62. When the sub-bearing connector 2 extends into and abuts against the bottom of the sleeve groove 62, the mother bearing connector 1 and the sub-bearing connector 2 cannot rotate relative to each other in the notch direction Y.

[0034] The closed rotating mechanism 3 is provided with a directional disengagement mechanism, which is arranged in the sleeve groove 62. The directional disengagement mechanism includes a hook 35 and a slot 36. The slot wall of the slot 36 restricts the hook 35 from moving in the opposite direction A of the sub-supporting connecting member 2 extending into the sleeve groove 62.

[0035] The folding and rotating mechanism 4 includes a folding through hole 41 , which is connected to one end of the closing through hole 34 , and the disengagement member 33 slides in the space formed by the folding through hole 41 and the closing through hole 34 .

[0036] The folding through hole 41 and the closing through hole 34 are both long holes, and the angle opening direction formed by the folding through hole 41 and the closing through hole 34 is opposite to the direction B in which the sub-support connecting member 2 extends into the sleeve groove.

[0037] The working principle is as follows: in the closed state, with O1, O2 and O3 as the rotation fulcrums, the female bearing connector 1 and the male bearing connector 2 cannot rotate in the Y direction, but can rotate in the X direction to leave the closed state.

[0038] The closure described in this embodiment refers to the state that the female connecting member 1 and the male connecting member 2 are unable to rotate in the Y direction.

[0039] In this embodiment, the limiting guide rail 32 can also be arranged on the sub-support connecting member 2, and the limiting protrusion 31 can be arranged on the female support connecting member 1;

[0040] In this embodiment, the closing through hole 34 can also be provided on the female support connecting member 1, and the anti-dropping member 33 can be provided on the male support connecting member 2. Example

[0041] like Figure 2 As shown, in the bidirectional rotating clutch folding device described in Example 1, the anti-reversal mechanism can also adopt the following technical methods:

[0042] The anti-reversal mechanism is provided with a concave contact surface on the limiting guide rail, and the limiting protrusion slides and / or rolls along the concave contact surface of the limiting guide rail; the anti-reversal mechanism is provided with a sleeve groove on the mother bearing connector, and the sub-bearing connector extends into the sleeve groove; the closing rotation mechanism and the folding rotation mechanism are both arranged on the contact surface of the mother bearing connector and the sub-bearing connector in the sleeve groove; the limiting guide rail is arranged at a position close to the slot opening of the sleeve groove, and the projection space S1 of the concave opening of the concave contact surface of the limiting guide rail intersects with the projection space S2 of the slot opening of the sleeve groove. When the sub-bearing connector extends into and abuts against the bottom of the sleeve groove, the mother bearing connector and the sub-bearing connector cannot rotate relative to each other in the direction of the slot opening.

[0043] This embodiment is further optimized as follows: the concave contact surface of the limiting guide rail is located in the sleeve groove, and the sleeve groove opening covers the concave opening of the concave contact surface of the limiting guide rail. Example

[0044] A tent using the above-mentioned folding device, the tent comprising a tarpaulin, more than three pairs of support rods and a folding device, the support rods comprising upper support rods and lower support rods that are stretched outward with the tent, one of the sub-support connector and the mother-support connector of the folding device is connected to the upper support rod, and the other is connected to the lower support rod; the tangent of the closing point of the trajectory of the sub-support connector and the mother-support connector to complete the closing is parallel to the tangent of the upper support rod and the lower support rod at the closing point, or the angle formed is less than 90 degrees, so that when the tent is opened, the tension of the tarpaulin can squeeze the sub-support connector and the mother-support connector to have a closing tendency.

[0045] The concave opening of the concave contact surface of the guide rail faces the connection direction of the upper support rod and the lower support rod. The folding direction of the upper support rod and the lower support rod is the same as the direction in which the folding device is disengaged from the closed state. When the external force acts in the folding direction and overcomes the force of the tarpaulin on the support rod, the folding device is disengaged from the closed state, the tarpaulin loses the force on the support rod, and the tent is folded. It is particularly pointed out that when the support rod pushes the tent outward, the hand acts in the direction of overcoming the pushing direction, that is, in the reverse direction.
