Description

Technical Field

[0001] The utility model relates to the technical field of door bars, and particularly relates to a sheet structure and a door bar with the same. Background Art

[0002] With the progress of social economy, people's safety awareness is getting higher and higher. Especially for children, not only the safety problems outdoors are emphasized, but also the safety problems indoors are emphasized. Therefore, parents usually set up safety door bars at positions such as indoor aisles and stairways to eliminate potential dangers.

[0003] At present, the safety door bars for children or pets on the market are generally of a sheet structure. One side of the sheet structure is rotatably connected to the installation position to be installed, and can swing along the rotation connection to realize the opening or closing action. A door bar lock is arranged on the other side of the sheet structure to lock the sheet structure.

[0004] In the prior art, the sheet structure is usually divided into those covered with a soft body and those not covered with a soft body. Compared with those not covered with a soft body, the sheet structure covered with a soft body uses less material and has a lower cost. For the convenience of packaging and transportation, the sheet structure is also provided with a folding structure. When the sheet structure is covered with a soft body, it can also be directly folded.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0042] The present utility model provides a sheet-like structure.

[0043] In the embodiments of the present utility model, as Figures 1 to 6 shown, the sheet-like structure includes a soft body 100. The upper and lower parts of the soft body 100 are respectively connected with an upper connecting rod 11 and a lower connecting rod 12. Both ends of the lower connecting rod 12 are pivotally connected with swing rods 13. The swing rods 13 can swing relative to the lower connecting rod 12 between positions where the free ends of the swing rods 13 approach the lower connecting rod 12 and the ends of the upper connecting rod 11. In addition, a locking mechanism is provided, and the locking mechanism is used to lock the free ends of the swing rods 13 and the ends of the upper connecting rod 11 after the free ends of the swing rods 13 approach the ends of the upper connecting rod 11.

[0044] Specifically, the locking mechanism includes a locking member 14 movably installed at the free end of the swing rod 13. A locking hole 15 is provided at the end of the upper connecting rod 11. The locking member 14 can move relative to the swing rod 13 between positions where it partially extends into and withdraws from the locking hole 15.

The locking member 14 is provided with a driving portion 141, and the locking member 14 can be driven through the driving portion 141 to move in the direction of partially withdrawing from the locking hole 15 against the elastic force applied by the first top spring.

[0046] Specifically, a first connection seat 16 is provided at the end of the upper connecting rod 11, and the locking hole 15 is provided in the first connection seat 16. The bottom of the locking hole 15 is open for a part of the locking member 14 to extend therein.

During the process of the free end of the swing rod 13 moving towards the direction of entering the receiving cavity, the contact and cooperation between the inclined surface and the inner wall of the receiving cavity 161 forces the locking member 14 to move in the direction of partially withdrawing from the locking hole 15 until the locking member 14 is aligned with the locking hole 15. Then, the elastic force applied by the first top spring forces a part of the locking member 14 to extend into the locking hole 15.

[0051] Specifically, in one embodiment, a step is provided at the bottom of the receiving cavity for the free end of the swing rod to abut against it vertically (the step is below and the free end of the swing rod is above), so as to prevent the first connection seat from moving away from the free end of the swing rod in the vertical direction.

A clamping groove 162 for cooperating with the clamping block is provided in the receiving cavity 161. When a part of the locking member extends into the locking hole, the clamping block is located in the clamping groove, so as to prevent the first connection seat from detaching from the swing rod in the vertical direction. While realizing the positioning of the locking hole 15 and the locking member 14, the connection between the upper end of the swing rod 13 and the first connection seat can also be strengthened, avoiding the situation that the upper connecting rod falls off due to the soft body relaxation.

[0052] Specifically, a second connection seat 17 is provided at the end of the lower connecting rod 12, and one end of the swing rod 13 is rotatably connected to the second connection seat 17.

[0068] Specifically, the fixing mechanism includes a moving part 33 movably mounted on the upper seat 3, and a vertically extending avoidance hole 331 is formed on one side of the moving part 33 close to the button 32. The button 32 is provided with a clamping portion 321 at a position above the avoidance hole 331. The moving part 33 can move relative to the upper seat 3 between a position where the avoidance hole 331 and the clamping portion 321 are offset to limit the button 32 and an alignment to release the restriction. When the avoidance hole 331 is aligned with the clamping portion 321, the button 32 can make the movement, and a fourth top spring 34 is also provided.

After the limiter 35 partially extends into the avoidance hole 331, it can limit the moving member 33 from moving in a direction where the avoidance hole 331 and the clamping portion 321 are staggered. A spring (not shown) is also provided, and the spring is used to apply an elastic force to the limiter 35 to move in a direction where the limiter 35 partially extends into the avoidance hole 331. When the button 32 moves to a position where the first telescopic member 25 is forced to withdraw from the first plug hole 31, the clamping portion 321 moves with it to force the limiter 35 to withdraw from the avoidance hole 331.

[0072] Specifically, the upper seat 3 is locked by screws or fixed to the position to be installed by a snap-on structure, or: the upper seat 3 is detachably mounted with a first back plate 36 for fixing to the position to be installed, the upper seat 3 is provided with a first slot 37 for the first back plate 36 to be inserted from bottom to top (or from top to bottom), the first slot 37 is partially opened on one side close to the position to be installed so that part of the first back plate 36 is exposed to the outside, the upper seat 3 is also movably mounted with a locking key 38, the locking member 14 can move between a position where the first back plate 36 is partially inserted into the first slot 37 to restrict the first back plate 36 from exiting the first slot 37 and a position where the restriction is released away from the first back plate 36 relative to the upper seat 3, and a fifth top spring 39 is further provided, the fifth top spring 39 is used to apply an elastic force to the locking key 38 to move in a direction where the locking key 38 is partially inserted into the first back plate 36. When it is necessary to release the restriction of the locking key 38 on the first back plate 36, the locking key 38 can be forced to move in a direction away from the first back plate 36 by an external force.

[0073] Specifically, the upper seat 3 is formed by the cooperation of a cover body and a base.

[0074] Specifically, a third telescopic member 42 is movably installed on the lower seat 4. The third telescopic member 42 can move relative to the lower seat 4 between a position where it partially extends into the second slot 62 and a position where it withdraws. Additionally, a sixth top spring 43 is provided, and the sixth top spring 43 is used to apply an elastic force to the third telescopic member 42 to move it in the direction of partially extending into the second slot 62.

When the sheet-like structure performs a door-closing action, the second telescopic member 26 can be forced to move away from the second jack 41 through the second guiding surface until the second telescopic member 26 is aligned with the second jack 41 and then automatically extends into the second jack 41.

[0076] Specifically, the second telescopic member 26 is movably installed on one of the two first connecting seats 17.

[0077] Specifically, a sliding seat 61 and a second back plate 60 for fixing at the installation position to be installed are further provided. The sliding seat 61 is movably sleeved on the support rod 5. The sliding seat 61 is provided with a second slot 62 into which the second back plate 60 can be inserted from bottom to top (or from top to bottom). One side of the second slot 62 close to the installation position to be installed is partially open so that a part of the second back plate 60 is exposed. The installation position to be installed described herein is mainly a wall. When there is a skirting board on the wall, it is not conducive to the installation of the lower seat 4, and it is easy to cause the support rod 5 to tilt, resulting in the door threshold being skewed. Therefore, the double fixation is achieved through the sliding seat 61 with an adjustable installation position and the upper seat 3, so that the lower seat 4 can avoid the skirting board. At the same time, when the lower seat 4 is not fixed, it can also ensure that the support rod 5 will not tilt, so that the door threshold after assembly will not be skewed.

[0078] The technical solution of the utility model forms a sheet structure through the cooperation of a soft body, an upper connecting rod, a lower connecting rod and two swing rods. Among them, the upper connecting rod and the lower connecting rod are respectively fixedly connected to the upper part and the lower part of the soft body, and the two swing rods are respectively rotatably connected to the two ends of the lower connecting rod, so that the free ends of the swing rods can swing between a position close to the end of the upper connecting rod and a position far away from it. When the free ends of the swing rods swing to a position close to the end of the upper connecting rod, the free ends of the swing rods and the end of the upper connecting rod can be fixed through a locking mechanism, so as to cooperate with the soft body to form a square sheet structure. The overall structure is simple and easy to install. When storage is needed, first release the locking of the swing rods and the upper connecting rod by the locking mechanism, swing the swing rods to be close to the lower connecting rod to achieve partial folding, and then roll up the sheet structure from the direction of the lower connecting rod to the direction of the upper connecting rod until the sheet structure forms a roll. During the rolling process, the soft body wraps the swing rods and the lower connecting rod, effectively avoiding the occurrence of wrinkles and mess on the soft body of the folded sheet structure, which may cause inconvenience in packaging and possible damage to the soft body during the packaging process.

[0079] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the present utility model.
