Example

[0026] Please refer to Figures 1 to 5 As shown, the present invention discloses a central locking structure of a folding tent, including a first mold base 1, a second mold base 2, a connecting rod 3, a locking assembly 4 and a driving assembly 5. The connecting rod 3 is provided at the bottom of the first mold base 1, and an insertion port 21 for inserting the lower end of the connecting rod 3 is provided at the top of the second mold base 2. The second mold base 2 is provided with a locking cavity 22 connected to the insertion port 21. The locking assembly 4 is arranged in the locking cavity 22 for fixing the lower end of the connecting rod 3. The driving assembly 5 is used to drive the locking assembly 4 to lock or unlock the lower end of the connecting rod 3.

[0027] The locking assembly 4 includes a roller 41 and a plurality of latching teeth 42 arranged circumferentially on the outer wall of the roller 41. The side wall of the connecting rod 3 is axially provided with a plurality of latching grooves 31 adapted to the latching teeth 42. A driving shaft 43 is provided on both sides of the roller 41. The inner wall of the locking cavity 22 is provided with a first waist hole 23 for the driving shaft 43 to move. The driving assembly 5 drives the driving shaft 43 to move in the first waist hole 23 so that the latching teeth 42 on the outer wall of the roller 41 are engaged in the latching groove 31 or disengaged from the latching groove 31.

[0028] The first waist hole 23 is set at an angle, and the inclination angle is toward the connecting rod 3. When the driving shaft 43 is at the upper end position of the first waist hole 23, the locking tooth 42 of the roller 41 is locked in the slot 31 of the connecting rod 3, and is in a locked state. When the driving shaft 43 gradually moves downward, the locking tooth 42 slowly disengages from the slot 31, and is in an unlocked state.

[0029] The driving assembly 5 includes a sliding sleeve 51 and a spring member 52. The upper and lower ends of the second mold base 2 are respectively provided with an upper limit block 24 and a lower limit block 25. The sliding sleeve 51 is slidably sleeved on the outer wall of the second mold base 2 and is located between the upper limit block 24 and the lower limit block 25. The upper limit block 24 and the lower limit block 25 are used to limit the sliding stroke of the sliding sleeve 51. The sliding sleeve 51 and the lower limit block 25 are elastically connected by the spring member 52. The outer wall of the sliding sleeve 51 is provided with a second waist hole 511. The end of the drive shaft 43 passes through the first waist hole 23 and is movably inserted into the second waist hole 511. The second waist hole 511 is tilted, and the inclination angle of the second waist hole 511 is opposite to that of the first waist hole 23.

[0030] The two groups of first waist holes 23 are in an eight-shaped structure, and the two groups of second waist holes 511 are in an inverted eight-shaped structure.

[0031] The upper limit block 24 is fixedly set on the top of the second mold base 2, the lower limit block 25 is detachably set on the bottom end of the second mold base 2 by bolts, and the top end of the connecting rod 3 is detachably set on the bottom end of the first mold base 1 by bolts.

[0032] An upper mounting groove and a lower mounting groove are respectively provided at the bottom end of the sliding sleeve 51 and the top end of the lower limit block 25. The upper and lower ends of the spring member 52 are respectively inserted into the upper mounting groove and the lower mounting groove. The inner diameters of the upper mounting groove and the lower mounting groove are adapted to the outer diameter of the spring member 52 to prevent the spring member 52 from deviating and tilting left and right.

[0033] A limiting groove 26 is provided in the locking cavity 22 and above the first waist hole 23. The limiting groove 26 is used to cooperate with the slot 31 to limit the left and right positions of the locking assembly 4 when the latch 42 is latched into the slot 31, thereby preventing the roller 41 from shaking left and right when in the locked state.

[0034] In this embodiment, two sets of rollers 41 are located on either side of the connecting rod 3. The connecting rod 3 and the drive assembly 5 are adapted to the two sets of rollers 41. The two sets of rollers 41 cooperate to secure the two sides of the connecting rod 3, providing a good locking effect and positioning the two sides of the connecting rod 3 to prevent the connecting rod 3 from tilting left or right.

[0035] The inner diameter of the insertion port 21 is larger than the outer diameter of the connecting rod 3, which facilitates the insertion of the bottom end of the connecting rod 3; and the lower end of the insertion port 21 extends inward to form a limiting port 211, and the inner diameter of the limiting port 211 is adapted to the outer diameter of the connecting rod 3, which is used to position the circumferential side of the connecting rod 3 so that the connecting rod 3 is in a vertical state and does not tilt.

[0036] The bottom end of the connecting rod 3 extends inward to form a pushing head 32, and the cross-section of the pushing head 32 is a trapezoidal structure. When the bottom end of the connecting rod 3 is inserted into the locking cavity, due to the small width of the front end of the pushing head 32, the end of the pushing head 32 is stuck between the two groups of rollers 41, and then the rollers 41 are pushed downward along the first waist hole 23 along the trapezoidal oblique side of the pushing head 32, so that the bottom end of the connecting rod 3 is inserted between the two groups of rollers 41.

[0037] The first mold base 1 includes a first base body 11 and a plurality of first hinged seats 12 circumferentially arranged at the bottom of the first base body 11. The upper bone rod 6 is hingedly connected to the first hinged seat 12. The second mold base 2 includes a second base body 27 and a plurality of second hinged seats 28 circumferentially arranged at the top of the second base body 27. The second hinged seats 28 correspond to the first hinged seats 12. The lower bone rod 7 is hingedly connected to the second hinged seat 28, and the other end of the lower bone rod 7 is rotatably connected to the upper bone rod 6. The first hinged seat 12 is provided with a first hinge port 121, and the second hinged seat 28 is provided with a second hinge port 281. The first hinge port 121 and the second hinge port 281 are both L-shaped openings, and the opening directions are arranged in opposite directions.

[0038] During installation, the bottom end of the connecting rod 3 is inserted into the locking cavity 22 through the insertion port 21 , and the pushing head 32 at the bottom end of the connecting rod 3 pushes the roller 41 downward along the first waist hole 23 , so that the bottom end of the connecting rod 3 is inserted between the two groups of rollers 41 . Then, the spring tension of the spring member 52 automatically drives the sliding sleeve 51 to move up along the second die base 2. Since the end of the driving shaft 43 passes through the first waist hole 23 and is movably inserted into the second waist hole 511, and the inclination angle of the second waist hole 511 is opposite to that of the first waist hole 23, when the sliding sleeve 51 moves up, the second waist hole 511 drives the driving shaft 43 to move up on the first waist hole 23, so that the teeth 42 on the outer wall of the roller 41 are stuck in the groove 31 on the connecting rod 3. At this time, the upper limit block 24 at the upper end of the second die base 2 limits the upward end point of the sliding sleeve 51, preventing the sliding sleeve 51 from continuing to move up. The spring tension of the spring member 52 supports the sliding sleeve 51 to maintain this state, thereby realizing the locking state of the locking assembly 4 on the connecting rod 3.

[0039] When unlocking, the sliding sleeve 51 is driven downward along the second mold base 2 by manual external force. When the sliding sleeve 51 moves upward, the second waist hole 511 drives the drive shaft 43 to move up and down in the first waist hole 23, so that the teeth 42 on the outer wall of the roller 41 are disengaged from the teeth 42 on the connecting rod 3, and then the connecting rod 3 is pulled out from the locking cavity 22, and finally the upper bone rod 6 and the lower bone rod 7 are rotated and folded for storage.

[0040] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
