[0025] Reference Figure 1-2 A game fence connector includes an upper corner joint 1 and a lower corner joint 8, and the upper corner joint 1 and the lower corner joint 8 are rotatably connected to adjacent fence components 7 respectively.

[0026] A slot 6 is provided at the upper part of the upper corner joint 1, and an unlocking button 2 is inserted in the slot 6. A locking piece 17 is sleeved between the inner sides of the upper corner joint 1 and the lower corner joint 8, and a return spring 10 is sleeved at the lower end of the outer side of the locking piece 17. An angle adjustment structure is provided between the top of the locking piece 17 and the unlocking button 2, and the angle adjustment structure is used to adjust the angle between the upper corner joint 1 and the lower corner joint 8.

[0027] A first locking structure is provided between the upper portion of the locking member 17 and the upper corner joint 1 , and a second locking structure is provided between the lower portion of the locking member 17 and the lower corner joint 8 .

[0028] The angle adjustment structure includes a partition 18, an insert plate 4, a through hole 16, a tooth groove 5 and a shallow tooth groove 11. The partition 18 is installed on the inner side of the slot 6. The through hole 16 is opened on the partition 18. The tooth groove 5 is set at the bottom of the insert plate 4. The insert plate 4 passes through the through hole 16 and extends to the bottom of the partition 18. The tooth groove 5 and the shallow tooth groove 11 cooperate with each other.

[0029] The first locking structure includes a deep tooth groove 12 and a latch tooth 19. The latch tooth 19 is arranged in a ring array on the inner side of the upper corner joint 1. The deep tooth groove 12 is installed on the outer upper end of the locking member 17. The deep tooth groove 12 and the latch tooth 19 cooperate with each other. When the position of the locking member 17 is lowered, the deep tooth groove 12 and the latch tooth 19 are disengaged from each other.

[0030] The second locking structure includes an outer ring gear 13 and an inner ring gear 9. The inner ring gear 9 is arranged inside the lower corner joint 8, and the outer ring gear 13 is installed on the outer lower part of the locking piece 17. When the upper corner joint 1 and the lower corner joint 8 are locked, the outer ring gear 13 is clamped on the inner side of the inner ring gear 9, and the inner ring gear 9 and the outer ring gear 13 cooperate with each other.

[0031] When the upper corner joint 1 and the lower corner joint 8 are in an unlocked state, the outer gear ring 13 drops in height until the outer gear ring 13 is separated from the inner gear ring 9 .

[0032] The partition 18 is evenly provided with through positioning holes 15 , and a positioning block 3 is installed at the lower end of the unlocking button 2 . The positioning blocks 3 are respectively inserted into the positioning holes 15 at different positions. The unlocking button 2 is circular in shape, and its size matches that of the slot 6 .

[0033] The upper corner joint 1 and the lower corner joint 8 are rotatably set between two adjacent fence components 7 through the locking piece 17, the unlocking button 2 is inserted into the inner side of the slot 6, and the positioning block 3 at the bottom of the unlocking button 2 cooperates with the positioning hole 15 on the partition 18, so that the unlocking button 2 can be quickly inserted into the inner side of the slot 6.

[0034] When the angle between the fence components 7 needs to be adjusted, the groove 5 at the bottom of the plug plate 4 fits the shallow groove 11 at the top of the locking member 17. Figure 2 As shown, in the process of pressing the unlock button 2 downward, the tooth groove 5 slowly enters the inner side of the shallow tooth groove 11, and in the process of entering, it will not only drive the shallow tooth groove 11 to rotate a certain angle, but also the force in the vertical direction will drive the shallow tooth groove 11 together with the locking piece 17 to move downward. At this time, a reset spring 10 is arranged on the outside of the locking piece 17, and the reset spring 10 is located at the upper corner joint 1 and the lower corner joint 8. The reset spring 10 is compressed and has tension. In the process of the locking piece 17 moving downward, the upper deep tooth groove 12 and the latch tooth 19 are disengaged from each other, changing from a bite state to a separation state. At the same time, as the locking piece 17 moves downward, the outer tooth ring 13 on the locking piece 17 is also disengaged from the inner tooth ring 9 on the lower corner joint 8, so that the locking piece 17 loses the limitation between the upper corner joint 1 and the lower corner joint 8, and the fence assembly 7 can be adjusted at this time.

[0035] Since the gear teeth on the outside of the latch 19 are not inserted into the groove on the edge of the deep tooth groove 12, but the gear teeth of the latch 19 and the gear teeth of the deep tooth groove 12 are pressed against each other, and the same is true for the inner gear ring 9 and the outer gear ring 13 below, even if the external force is removed at this time, the fence assembly 7 will not be locked. When the unlocking button 2 is pressed again, the tooth groove 5 drives the shallow tooth groove 11 to rotate a certain distance. At this time, the gear teeth on the outside of the latch 19 are aligned with the groove on the edge of the deep tooth groove 12, and the same is true for the inner gear ring 9 and the outer gear ring 13 below. After the external force on the unlocking button 2 is removed, the deep tooth groove 12 can be effectively pushed into the latch 19 under the action of the tension of the reset spring 10, and the inner gear ring 9 and the outer gear ring 13 will also engage with each other.

[0036] Example 2

[0037] refer to Figure 1-3 The difference between this embodiment and embodiment 1 is that a base 14 is provided at the bottom of the lower corner joint 8, a through first connecting hole 20 is provided at the top of the locking piece 17, a through second connecting hole 21 is provided in the middle of the base 14, and the first connecting hole 20 is connected to the second connecting hole 21 through the inside of the locking piece 17.

[0038] When the unlocking button 2 is installed in the slot 6, in order to prevent the problem of negative pressure inside the structure, the base 14 is set to be in a hollow state with the middle part bulging upward. At the same time, the interior of the locking piece 17 is also hollow, and the lower end is opened. A first connecting hole 20 and a second connecting hole 21 are respectively opened on the locking piece 17 and the base 14 to form air convection. When the unlocking button 2 is pulled out, the problem of being unable to be pulled out due to negative pressure is prevented.

[0039] The working principle of the device is:

[0040] The upper corner joint 1 and the lower corner joint 8 are rotatably set between two adjacent fence components 7 through the locking piece 17, the unlocking button 2 is inserted into the inner side of the slot 6, and the positioning block 3 at the bottom of the unlocking button 2 cooperates with the positioning hole 15 on the partition 18, so that the unlocking button 2 can be quickly inserted into the inner side of the slot 6.

[0041] When the angle between the fence components 7 needs to be adjusted, the groove 5 at the bottom of the plug plate 4 fits the shallow groove 11 at the top of the locking member 17. Figure 2As shown, in the process of pressing the unlock button 2 downward, the tooth groove 5 slowly enters the inner side of the shallow tooth groove 11, and in the process of entering, it will not only drive the shallow tooth groove 11 to rotate a certain angle, but also the force in the vertical direction will drive the shallow tooth groove 11 together with the locking piece 17 to move downward. At this time, a reset spring 10 is arranged on the outside of the locking piece 17, and the reset spring 10 is located at the upper corner joint 1 and the lower corner joint 8. The reset spring 10 is compressed and has tension. In the process of the locking piece 17 moving downward, the upper deep tooth groove 12 and the latch tooth 19 are disengaged from each other, changing from a bite state to a separation state. At the same time, as the locking piece 17 moves downward, the outer tooth ring 13 on the locking piece 17 is also disengaged from the inner tooth ring 9 on the lower corner joint 8, so that the locking piece 17 loses the limitation between the upper corner joint 1 and the lower corner joint 8, and the fence assembly 7 can be adjusted at this time.

[0042] Since the gear teeth on the outside of the latch 19 are not inserted into the groove on the edge of the deep tooth groove 12, but the gear teeth of the latch 19 and the gear teeth of the deep tooth groove 12 are pressed against each other, and the same is true for the inner gear ring 9 and the outer gear ring 13 below, even if the external force is removed at this time, the fence assembly 7 will not be locked. When the unlocking button 2 is pressed again, the tooth groove 5 drives the shallow tooth groove 11 to rotate a certain distance. At this time, the gear teeth on the outside of the latch 19 are aligned with the groove on the edge of the deep tooth groove 12, and the same is true for the inner gear ring 9 and the outer gear ring 13 below. After the external force on the unlocking button 2 is removed, the deep tooth groove 12 can be effectively pushed into the latch 19 under the action of the tension of the reset spring 10, and the inner gear ring 9 and the outer gear ring 13 will also engage with each other.

[0043] When the unlocking button 2 is installed in the slot 6, in order to prevent the problem of negative pressure inside the structure, the base 14 is set to be in a hollow state with the middle part bulging upward. At the same time, the interior of the locking piece 17 is also hollow, and the lower end is opened. A first connecting hole 20 and a second connecting hole 21 are respectively opened on the locking piece 17 and the base 14 to form air convection. When the unlocking button 2 is pulled out, the problem of being unable to be pulled out due to negative pressure is prevented.
