[0002] Families with infants often install a sliding gate in the aisle to prevent them from getting lost or getting hurt. The sliding gate is usually composed of two movable door bodies. The gate can be made longer or shorter by moving one of the door bodies. When installing, the length of the gate can be adjusted according to the length of the aisle, and then one side of the gate can be pivotally installed at the installation position so that the gate can swing between the position of disconnecting the aisle and the position of opening. When the gate swings to the position of disconnecting the aisle, the other side of the gate can be locked by the gate lock. Since one side is a pivoting structure for swinging the gate and the other side is a locking structure for fixing the gate, this type of sliding gate is open on one side. The sliding gate with the same structure and operation is difficult to arouse consumers' attention and interest. Utility Model Content

[0015] The utility model provides a safety door fence with doors opened on both sides.

[0016] In the embodiment of the utility model, Figures 1 to 6As shown, the safety gate fence with doors opened on both sides includes two door bodies 100 movably connected to each other. One of the two door bodies 100 can make a linear reciprocating movement in the horizontal direction relative to the other so that the two door bodies 100 overlap or stagger. One side of the door body 100 is detachably pivotally connected with a positioning mechanism 200. The positioning mechanism 200 is used to be fixed in a position to be assembled so that the door body 100 can be horizontally swung relative to the position to be assembled to realize the door opening or closing action.

[0017] The technical solution of the utility model is to first fix the two positioning mechanisms at the installation position in a manner of being spaced opposite to each other at a left and right interval during installation, and adjust one of the two door bodies to move horizontally relative to the other according to the spacing between the two positioning mechanisms, thereby increasing or decreasing the length, so that one side of each of the two door bodies can be detachably pivoted with the two positioning mechanisms respectively, and after one side of the pivotal cooperation on both sides is released, the door body can swing through the pivotal cooperation on the other side that has not been released as the rotation center to realize the door opening and closing actions, so that the user can choose to open the door from the left or right according to needs. Compared with the traditional one, the overall structure is simple, and when necessary, the pivotal cooperation on both sides can be released at the same time to quickly remove the door body, which has excellent practicality and novelty.

[0018] It should be noted that the mutual movable connection structure between the two door bodies 100 can refer to the existing technology, and its specific structural principle will not be repeated here.

[0019] Specifically, the positioning mechanism 200 includes a support rod 1 and an upper seat 2 and a lower seat 3 respectively disposed at both ends of the support rod 1 , and the upper seat 2 and the lower seat 3 are respectively detachably pivotally matched with the top and the bottom of the door body 100 .

[0020] Specifically, the bottom of the upper seat 2 and the top of the lower seat 3 are respectively provided with a first connecting hole 21 and a second connecting hole 31, and the top and bottom of the door body 100 are respectively provided with a first connecting member 101 for movably plugging into the first connecting hole 21 and a second connecting member 102 for movably plugging into the second connecting hole 31, and the first connecting member 101 can move between the position of plugging into and withdrawing from the first connecting hole 21 relative to the door body 100, and an unlocking member 22 is further provided for driving the first connecting member 101 to move in the direction of withdrawing from the first connecting hole 21 to release the cooperation between the upper seat 2 and the top of the door body 100.

[0021] When opening the door, the first connecting member 101 is driven to withdraw from the first connecting hole 21 through the unlocking member 22, so that the top of the door body 100 is disconnected from the upper seat 2, and the door body 100 is moved to stagger the first connecting member 101 with the first connecting hole 21. Since the door body 100 and the positioning mechanism 200 are not completely tightly matched, the door body 100 can be slightly lifted to pull the second connecting member 102 out of the second connecting hole 31, so as to realize the disassembly of the door body 100 and the positioning mechanism 200, that is, the unlocking action of the safety gate. In this embodiment, the structures of the two door bodies 100 are the same, and the structures of the two positioning mechanisms 200 are also the same, so both sides of the safety gate can realize the unlocking and opening action.

[0022] Specifically, in one embodiment, the first connecting member 101 is connected to the unlocking member 22, and the unlocking member 22 can drive the first connecting member 101 to move to be plugged into the first connecting hole 21 or withdraw from the first connecting hole 21. In this embodiment, a first top spring 103 is further provided, and the first top spring 103 is used to apply an elastic force to the first connecting member 101 to move in the direction of plugging into the first connecting hole 21. When closing the door, the first connecting member 101 can be forced to move away from the first connecting hole 21 by an external force, so that the first top spring 103 is compressed, until the first connecting member 101 is aligned with the first connecting hole 21, and the first top spring 103 is released from compression and releases the elastic force so that a part of the first connecting member 101 automatically extends into the first connecting hole 21.

[0023] Specifically, in this embodiment, the bottom of the upper seat 2 is provided with a first guide surface 23 for contacting the top of the first connecting member 101. When the door body 100 swings in the door closing direction, the first guide surface 23 can contact the top of the first connecting member 101 and guide the first connecting member 101 to move away from the first connecting hole 21 to compress the first top spring 103 as the door body 100 continues to swing.

[0024] Specifically, the second connecting member 102 can move between the position of being plugged into and out of the second connecting hole 31 relative to the door body 100, and is further provided with a second top spring 104, which is used to apply an elastic force to the second connecting member 102 to move in the direction of plugging into the second connecting hole 31. When closing the door, the second connecting member 102 can be forced to move away from the second connecting hole 31 by an external force, so that the second top spring 104 is compressed, until the second connecting member 102 is aligned with the second connecting hole 31, and the second top spring 104 is decompressed and releases the elastic force, so that a part of the second connecting member 102 automatically extends into the second connecting hole 31.

[0025] Specifically, in this embodiment, a second guide surface 32 is provided on the top of the lower seat 3 for contacting the bottom of the second connecting member 102. When the door body 100 swings in the door closing direction, the second guide surface 32 can contact the bottom of the second connecting member 102 and guide the second connecting member 102 to move away from the second connecting hole 31 to compress the second top spring 104 during the continuous swinging of the door body 100.

[0026] Specifically, a movable block 33 is movably provided inside the lower seat 3. The movable block 33 can move between a position where it partially extends into the second connection hole 31 and a position where it exits. A third top spring 34 is also provided. The third top spring 34 is used to apply an elastic force to the movable block 33 to move in a direction where it partially extends into the second connection hole 31. The lower end of the second connection member 102 is a spherical surface, and the movable block 33 is provided with a third guide surface 331 for contacting the spherical surface. In the process where the second top spring 104 releases the elastic force to allow the lower end of the second connection member 102 to spring into the second connection hole 31, the third guide surface 331 can cooperate with the spherical surface to force the movable block 33 to move to a certain position in a direction where it exits the second connection hole 31, and the elastic force applied by the second top spring 104 and the elastic force applied by the third top spring 34 can keep the movable block 33 in contact with the peripheral wall of the second connection member 102. When the first connection member 101 is offset from the first connection hole 21, the second connection member 102 can be tilted to a certain extent, so that the spherical surface is displaced to contact with the third guide surface 331. At the same time, the elastic force applied by the third top spring 34 forces the second connecting member 102 to move in the direction away from the second connecting hole 31. Of course, the elastic force applied by the third top spring 34 cannot make the second connecting member 102 completely withdraw from the second connecting hole 31. It is necessary to further force the second connecting member 102 to completely withdraw from the second connecting hole 31 through the cooperation between the opening of the second connecting hole 31 and the spherical surface during the process of swinging the door body 100 by external force. In this way, the cooperation between the lower seat 3 and the bottom of the door body 100 can be released without lifting the lower part of the door body 100 to pull the second connecting member 102 out of the second connecting hole 31.

[0027] Specifically, the top wall of the moving block 33 is provided with a first mark (not shown) for indicating a locked state and a second mark (not shown) for indicating an unlocked state. The lower seat 3 is provided with a first window 35 at a position corresponding to the top of the moving block 33. The moving block 33 can move between a position in which the first mark is aligned with the first window 35 and a position in which the second mark is aligned with the first window 35. When the first mark is aligned with the first window 35, the moving block 33 elastically resists against the peripheral wall of the second connecting member 102, and the second top spring 104 can apply an elastic force to the moving block 33 to move in the direction of alignment of the second mark with the first window 35.

[0028] Specifically, there are many ways to fix the positioning mechanism 200 to the position to be assembled. For example, the support rod 1, the upper seat 2 and the lower seat 3 can be locked to the position to be assembled by screws. The position to be assembled is usually a wall. Some walls are provided with skirtings. In order to avoid the skirtings and prevent the support rod 1 from tilting, in this embodiment, the positioning mechanism 200 also includes a sliding seat 4 movably mounted on the support rod 1. The sliding seat 4 is used to be fixedly connected to the position to be assembled to realize the connection between the positioning mechanism 200 and the position to be assembled.

[0029] Specifically, the sliding seat 4 and the upper seat 2 can be fixed to the wall by screw locking or a quick-release structure so that the support rod 1 avoids the skirting and avoids the positioning mechanism 200 from tilting.

[0030] It should be noted that the quick release mechanism can refer to the prior art, and its specific structural principle will not be described in detail here.

[0031] Specifically, the unlocking member 22 has multiple implementation modes. In the present embodiment, a socket 24 aligned with the first connecting hole 21 is provided inside the upper seat 2, and the unlocking member 22 is provided with a connecting shaft 221 for movably plugging into the socket 24. The unlocking member 22 can be pivotally mounted on the upper seat 2 through the cooperation between the connecting shaft 221 and the socket 24 and can make vertical reciprocating motion along the socket 24. During the downward movement of the unlocking member 22, the connecting shaft 221 can contact the first connecting member 101 and drive the first connecting member 101 to move in the direction of exiting the first connecting hole 21 to force the first connecting member 101 to exit the first connecting hole 21.

[0032] Specifically, a base 25 with the insertion hole 24 is provided inside the upper seat 2, the unlocking member 22 is provided with a limiting portion 222, and the base 25 is provided with a limiting groove 251. The limiting portion 222 can swing between the upper and lower aligned and staggered positions with the pivoting of the unlocking member 22. When the limiting portion 222 is aligned with the limiting groove 251, the unlocking member 22 can drive the limiting portion 222 to be inserted into the limiting groove 251 during the process of downward driving the first connecting member 101 to exit the first connecting hole 21. A first torsion spring 26 is also provided. The first torsion spring 26 is used to apply an elastic force to the unlocking member 22 to pivot in the staggered direction of the limiting portion 222 and the limiting groove 251. When the limiting portion 222 is inserted into the limiting groove 251, affected by the elastic force applied by the first torsion spring 26, the limiting portion 222 remains against the inner wall of the limiting groove 251. When the elastic force applied by the first top spring 103 causes the first connecting member 101 to be partially inserted into the first connecting hole 21, the unlocking member 22 can be lifted up by the connecting shaft 221 to drive the limiting portion 222 to exit the limiting groove 251. After the limiting portion 222 exits the limiting groove 251, the elastic force applied by the first torsion spring 26 forces the unlocking member 22 to pivot and drive the limiting portion 222 to swing to a position offset from the limiting groove 251, thereby realizing automatic resetting of the unlocking member 22.

[0033] Specifically, a slider 27 is movably installed inside the upper seat 2, and a third mark 271 for indicating a locked state and a fourth mark 272 for indicating an unlocked state are arranged on the top of the slider 27. A second window 20 is opened on the top of the upper seat 2, and the slider 27 can move between a position where the third mark 271 is vertically aligned with the second window 20 and a position where the fourth mark 272 is vertically aligned with the second window 20. A fourth top spring 273 is also provided, and the fourth top spring 273 is used to apply an elastic force to the slider 27 to move in a direction in which the third mark 271 is vertically aligned with the second window 20. A fourth guide surface 274 is provided on a side of the slider 27 close to the base 25. During the downward process of the unlocking member 22, a part of it contacts the fourth guide surface 274 and is guided by the fourth guide surface 274 to force the slider 27 to move in a direction in which the fourth mark 272 is vertically aligned with the second window 20, and compress the fourth top spring 273, so that after the top of the door body 100 is disconnected from the upper seat 2, the fourth mark 272 indicating the unlocked state can be viewed from the second window 20. When the unlocking member 22 is lifted, the fourth top spring 273 is decompressed and releases the elastic force to move the slider 27 in the direction of the third mark 271 and the second window 20 to be aligned vertically, so that after the top of the door body 100 is connected to the upper seat 2, the third mark 271 indicating the locked state can be viewed from the second window 20.

[0034] Specifically, the base 25 is pivotably sleeved with a ring 28 that surrounds the jack 24 therein, and the outer wall of the ring 28 is formed with a driving portion 281 for contacting the limiting portion 222. One end of the first torsion spring 26 is connected to the base 25, and the other end is connected to the ring 28. During the swinging process of the limiting portion 222 in the direction aligned with the limiting groove 251, the limiting portion 222 contacts the driving portion 281 and pushes the ring 28 to pivot to compress the first torsion spring 26, and the first torsion spring 26 is kept compressed by inserting the limiting portion 222 into the limiting groove 251. After the limiting portion 222 exits the limiting groove 251, the first torsion spring 26 is decompressed and releases the elastic force to pivot the ring 28 to push the limiting portion 222 to swing in the direction offset from the limiting groove 251 through the driving portion 281.

[0035] Specifically, a positioning piece 282 is fixed at a position above the base 25 corresponding to the ring 28, and a stopper 283 is formed on the outer wall of the ring 28 for abutting against the outer wall of the positioning piece 282 to prevent the ring 28 from excessively pivoting and to avoid the situation where the limiting portion 222 cannot contact the driving portion 281 to push the ring 28 to pivot.

[0036] Specifically, a swinging member 29 having a fifth guide surface 291 is pivotally mounted inside the upper seat 2, and a second torsion spring 292 is further provided. The second torsion spring 292 is used to apply an elastic force to the swinging member 29 to swing in a direction in which the end of the swinging member 29 contacts the unlocking member 22;

[0037] The unlocking member 22 is provided with a latching position 223, and the latching position 223 can swing between a position aligned with and away from the end of the swinging member 29 as the unlocking member 22 pivots. When the limiting portion 222 is aligned with the limiting groove 251 up and down, the end of the swinging member 29 is aligned with the latching position 223 and the elastic force applied by the second torsion spring 292 causes the end of the swinging member 29 to be latched into the latching position 223 to resist the elastic force applied by the first torsion spring 26, so that the unlocking member 22 maintains the current state. Thereafter, during the process of the limiting portion 222 being inserted into the limiting groove 251, the unlocking member 22 partially contacts the fifth guide surface 291 and forces the swinging member 29 to swing in a direction away from the unlocking member 22, so that the end of the swinging member 29 is away from the latching position 223, and the latching position 223 moves to the bottom of the end of the swinging member 29 with the unlocking member 22.

[0038] The limiting groove 251 is relatively wide, allowing the limiting portion 222 to swing horizontally therein. After being inserted into the limiting groove 251, the limiting portion 222 is affected by the elastic force of the first torsion spring 26 and swings to keep against the inner wall of the limiting groove 251, while driving the latch 223 to move, so that the latch 223 is staggered with the end of the swinging member 29. In this way, when the limiting portion 222 exits the limiting groove 251, the latch 223 can rise to a position that is in the same horizontal plane as the end of the swinging member 29 but is not re-engaged with the end of the swinging member 29, so that after the first torsion spring 26 releases the elastic force, the limiting portion 222 can smoothly swing in the direction staggered with the limiting groove 251, thereby realizing the reset of the unlocking member 22 and the latch 223 at the same time.

[0039] Specifically, the upper seat 2 includes a cover body and a base, the unlocking member 22 is in the shape of a cap, and a flange 224 that can contact the fifth guide surface 291 is formed at a position corresponding to the bottom of the outer peripheral wall of the unlocking member 22, and the locking position 223 is arranged on the flange 224. The swinging member 29 is also provided with a sixth guide surface 293 that can contact the flange 224. In the process of the limiting part 222 withdrawing from the limiting groove 251, the flange 224 and the sixth guide surface 293 can cooperate to force the end of the swinging member 29 to swing in a direction away from the unlocking member 22, so as to avoid the flange 224 and the swinging member 29 being abutted against each other up and down during the process of the limiting part 222 withdrawing from the limiting groove 251, resulting in the limiting part 222 being unable to withdraw from the limiting groove 251.

[0040] Specifically, the cover body is formed with an avoidance hole 01 suitable for the unlocking member 22, and the unlocking member 22 partially passes through the avoidance hole 01 and is exposed to the outside, and the flange 224 can be limitedly matched with the inner wall of the cover body to prevent the unlocking member 22 from completely passing through the avoidance hole 01.

[0041] Specifically, a gripping portion 225 is formed on the top of the unlocking member 22 .

[0042] Specifically, the door body 100 is a foldable structure or a non-foldable structure, and specific details may refer to the prior art, or refer to the following embodiments: the door body 100 is formed by connecting two horizontal bars and two vertical bars, and both ends of the horizontal bar are provided with angle seats for connecting with the ends of the vertical bars, one of the angle seats at both ends of the horizontal bar located at the top of the door body 100 is provided with the first connecting member 101, and one of the angle seats at both ends of the horizontal bar located at the bottom of the door body 100 is provided with the second connecting member 102, and a joint is provided in the middle of the vertical bar, so that the two ends of the vertical bar can swing between close and separated positions, thereby realizing the folding action of the door body 100.

[0043] Specifically, the door body 100 is also covered with software.

[0044] Specifically, rollers 105 are further provided at the bottom of the door body 100 to facilitate transportation of the door body 100 .

[0045] It should be noted that the above embodiments disclose the beneficial effect of the utility model that the door can be opened on both sides. In practical applications, the utility model also includes the effect of opening the door on one side, which can be achieved by simply replacing the positioning mechanism 200 on one side with a door lock.

[0046] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.

The unlocking member (22) can be pivotally mounted on the upper seat (2) through the cooperation between the connecting shaft (221) and the plug hole (24) and can perform vertical reciprocating motion along the plug hole (24). During the downward motion of the unlocking member (22), the connecting shaft (221) can contact the first connecting member (101) and drive the first connecting member (101) to move in a direction of exiting the first connecting hole (21) so as to force the first connecting member (101) to exit the first connecting hole (21).

11. The safety gate with doors opening on both sides as claimed in claim 10, characterized in that: A base (25) having the insertion hole (24) is provided inside the upper seat (2); the unlocking member (22) is provided with a limiting portion (222); the base (25) is provided with a limiting groove (251); the limiting portion (222) can swing between a position aligned with and offset from the limiting groove (251) as the unlocking member (22) pivots; when the limiting portion (222) is aligned with the limiting groove (251), the unlocking member (22) can drive the limiting portion (222) to be inserted into the limiting groove (251) in the process of driving the first connecting member (101) to exit the first connecting hole (21) downward; a first torsion spring (26) is further provided, and the first torsion spring (26) is used to apply an elastic force to the unlocking member (22) to pivot in the offset direction of the limiting portion (222) and the limiting groove (251).

12. The safety gate with doors opening on both sides as claimed in claim 11, characterized in that: The base (25) is pivotably sleeved with a sleeve (28) surrounding the insertion hole (24); the outer wall of the sleeve (28) is formed with a driving part (281) for contacting the limiting part (222); one end of the first torsion spring (26) is connected to the base (25), and the other end is connected to the sleeve (28); when the limiting part (222) swings in the direction aligned with the limiting groove (251), it contacts the driving part (281) and pushes the sleeve (28) to pivot, so that the first torsion spring (26) is compressed; and the first torsion spring (26) is kept compressed by inserting the limiting part (222) into the limiting groove (251); after the limiting part (222) exits the limiting groove (251), the first torsion spring (26) is released from compression and releases elastic force, so that the sleeve (28) pivots, so as to push the limiting part (222) to swing in the direction offset from the limiting groove (251) through the driving part (281).

13. The safety gate with doors opening on both sides as claimed in claim 12, characterized in that: A positioning piece (282) is fixed to the base (25) at a position above the corresponding collar (28), and a stopper (283) is formed on the outer wall of the collar (28) for abutting against the outer wall of the positioning piece (282) to prevent the collar (28) from excessively pivoting.

14. The safety gate with doors opening on both sides as claimed in claim 11, characterized in that: A swinging member (29) having a fifth guide surface (291) is pivotally mounted inside the upper seat (2), and a second torsion spring (292) is also provided, wherein the second torsion spring (292) is used to apply an elastic force to the swinging member (29) to swing in a direction in which the end of the swinging member (29) contacts the unlocking member (22); The unlocking member (22) is provided with a latching position (223), and the latching position (223) can swing between a position aligned with and away from the end of the swinging member (29) as the unlocking member (22) pivots. When the limiting portion (222) is aligned with the limiting groove (251) up and down, the end of the swinging member (29) is aligned with the latching position (223) and the end of the swinging member (29) is latched into the latching position (223) by the elastic force applied by the second torsion spring (292) to resist the elastic force applied by the first torsion spring (26), so that the unlocking member (22) maintains a current state. Thereafter, during the process of the limiting portion (222) being inserted into the limiting groove (251), the unlocking member (22) partially contacts the fifth guide surface (291) and forces the swinging member (29) to swing in a direction away from the unlocking member (22), so that the end of the swinging member (29) is away from the latching position (223), and the latching position (223) moves to below the end of the swinging member (29) along with the unlocking member (22); The width of the limiting groove (251) is relatively large, allowing the limiting portion (222) to swing horizontally therein. After being inserted into the limiting groove (251), the limiting portion (222) is influenced by the elastic force of the first torsion spring (26) to swing until it is in contact with the inner wall of the limiting groove (251), and at the same time drives the clamping portion (223) to move, so that the clamping portion (223) is offset from the end of the swinging member (29).

15. The safety gate with doors opening on both sides as claimed in claim 14, characterized in that: The upper seat (2) comprises a cover body and a base, the unlocking member (22) is in the shape of a cap, a flange (224) capable of contacting the fifth guide surface (291) is formed at a position of the outer peripheral wall of the unlocking member (22) corresponding to the bottom, the locking position (223) is arranged on the flange (224), and the swinging member (29) is also provided with a sixth guide surface (293) capable of contacting the flange (224). When the limiting portion (222) exits the limiting groove (251), the flange (224) and the sixth guide surface (293) can cooperate to force the end of the swinging member (29) to swing in a direction away from the unlocking member (22).
