Description

Technical Field

[0001] The utility model relates to a guardrail neighborhood, in particular to a door guardrail with an opening. Background Art

[0002] In the absence of a door or when the door is open, in order to prevent young children or pets from running out of the restricted area, door guardrail products have appeared. After the door guardrail is installed, pets or young children can only leave by opening the guardrail, which is inconvenient to operate. In order to facilitate the entry and exit of pets or young children, another opening is opened on the guardrail. In order to facilitate the opening or closing of the opening, a movable baffle is usually set on the guardrail to realize the opening and closing of the guardrail opening. However, the existing movable baffles are mostly limited by complex structures, and the limiting is not stable enough. Since the movable baffle is used frequently, the limiting device or positioning device is prone to malfunction and damage, and it is inconvenient to operate. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a door guardrail with an opening. By streamlining and optimizing the structure of the positioning device, the failure rate is reduced, the structural stability and ease of operation are improved, and the positioning device is more stably fixed, preventing the movable baffle from accidentally opening or closing, thereby improving safety and efficiency. The present invention is suitable for a door guardrail with an opening.

[0004] The technical solution adopted by the utility model is: a door guardrail with an opening, including a guardrail body, the guardrail body including a plurality of vertical rods, an opening is provided at the lower part of the guardrail body, a horizontal rod that cuts off the vertical rods is provided above the opening, a movable baffle that can slide up and down and open or close the opening is provided on the guardrail body, a positioning device is provided on the movable baffle, the positioning device can limit the relative movement of the movable baffle and the guardrail body so that the opening is in an open state, and is characterized in that at least one of the plurality of vertical rods passes through the movable baffle and cooperates with the positioning device The positioning is achieved by combining the two devices. The positioning device includes a slider that can move laterally, a latch is provided at the front of the slider, and an upper limit opening is provided on the corresponding vertical rod that cooperates with the positioning device. When the latch is inserted into the upper limit opening, the movable baffle is fixed in a high position, and the opening is in an open state. The interior of the movable baffle is provided with a guide rail cavity for the movement of the slider, and the outer side of the baffle is provided with a paddle connected to the slider and controlling the movement of the slider. The latch can be controlled to be extended and retracted by controlling the paddle. The structure is simple, the failure rate is low, and it is easy to operate. The movable baffle will not slide off easily, and it has high stability and safety.

[0005] A better method is to provide a door guardrail with an opening, characterized in that a lower limit opening is also provided on the vertical rod that cooperates with the positioning device. When the latch is inserted into the lower limit opening, the movable baffle is fixed in a low position, and the opening is in a closed state. When the opening is closed, the movable baffle will not be easily opened by animals or babies, and the safety is higher.

[0006] A better method is to provide a door guardrail with an opening, characterized in that a return spring is provided at the rear of the slider to push the slider forward. When the paddle is in a non-stressed state, the pin on the slider is firmly inserted into the upper limit opening or the lower limit opening by the action of the return spring. When the pin disengages from the upper limit opening or the lower limit opening and slides up and down, the pin is compressed by the surface of the vertical rod and is in a retracted state. The return spring accumulates force and contracts. When the pin moves to the upper limit opening or the lower limit opening position, the pin automatically bounces into the upper limit opening or the lower limit opening under the elastic force of the return spring to achieve position fixing, making operation easier.

[0007] A better method is to provide a door guardrail with an opening, characterized in that two positioning devices are provided on the movable baffle, and the positions of the two positioning devices are symmetrical with each other. The sliders of the two positioning devices slide in opposite directions under the action of the reset springs, and the front parts of the corresponding two positioning devices are provided with vertical rods that cooperate with each positioning device. The surfaces of the two vertical rods that fit with the pins on both sides are respectively provided with upper limit openings and lower limit openings that are symmetrical and of the same height. The setting of the two positioning devices makes the position of the movable baffle more stably fixed.

[0008] A better method is to provide a door guardrail with an opening, characterized in that the heights of the paddles on the two positioning devices gradually increase toward the rear, and the paddles on both sides can be pinched by two fingers at the same time to achieve the synchronous backward contraction of the pins on both sides, so that the pins on both sides are simultaneously disengaged from the upper limit opening or the lower limit opening, making it easier to manipulate the paddles to disengage the pins from the upper limit opening or the lower limit opening, allowing the movable baffle to slide up and down.

[0009] A better method is to provide a door guardrail with an opening, characterized in that a bottom plate is provided at the bottom of the movable baffle. When the movable baffle is in a high position, the bottom plate limits the movable baffle from continuing to slide upward, and also further realizes the accurate coordination of the latch and the upper limit opening, effectively preventing the latch from sliding over the upper limit opening.

[0010] This solution reduces the failure rate, improves the stability of the structure and the convenience of operation by streamlining and optimizing the structure of the positioning device. The positioning device is more stably fixed, effectively preventing the movable baffle from opening or closing by mistake, and improving safety and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model provides a door guardrail with an opening, which is suitable for guardrail neighborhoods. The utility model can be implemented in the following ways:

[0021] like Figure 1-6 As shown: A door guardrail with an opening, including a guardrail body 1, the guardrail body 1 includes a plurality of vertical rods 12, an opening 11 is provided at the lower part of the guardrail body 1, a horizontal rod 13 is provided above the opening 11 to cut off the vertical rod 12, a movable baffle 2 is provided on the guardrail body 1 that can slide up and down to open or close the opening 11, two positioning devices 3 are provided on the top of the movable baffle 2, and the positions of the two positioning devices 3 are symmetrical in opposite directions; a slider 31 that can move laterally is provided in the positioning device 3, a latch 311 is provided at the front of the slider 31, and the two positioning devices 3 are provided at the top of the movable baffle 2. The front part, that is, both sides of the two positioning devices 3, are provided with vertical rods 12 that cooperate with the positioning devices 3. The two vertical rods 12 pass through the movable baffle 2. An upper limit opening 5 and a lower limit opening 6 are provided on the vertical rods 12. The two upper limit openings 5 are symmetrical to each other and have the same height, and the two lower limit openings 6 are symmetrical to each other and have the same height; when the pins 311 on both sides are inserted into the upper limit openings 5, the movable baffle 2 is fixed in the high position, and the opening 11 is in the open state; when the pins 311 on both sides are inserted into the lower limit openings 6, the movable baffle 2 is fixed in the low position, and the opening 11 is in the closed state.

[0022] The movable baffle 2 is provided with two guide rail cavities 4 for the movement of the slider 31. The positions of the two guide rail cavities 4 are also symmetrical. A paddle 33 connected to the slider 31 and controlling the movement of the slider 31 is provided on the top outer side of the baffle 2. The latch 311 can be controlled to extend and retract by controlling the paddle 33. A return spring 32 is provided in the guide rail cavity 4 and at the rear of the slider 31 to push the slider 31 forward. When the paddle 33 is not under force, the latch 311 on the slider 31 is under force. When the latch 311 moves to the upper limit opening 5 or the lower limit opening 6 position, the latch 311 is automatically rebounded into the upper limit opening 5 or the lower limit opening 6 by the elastic force of the reset spring 32, so as to achieve position fixing and easier operation.

[0023] Since the two positioning devices 3 are designed to be back to back as a whole, the heights of the paddles 33 on the two positioning devices 3 gradually increase towards the rear. The paddles 33 on both sides can be pinched by two fingers at the same time to bring the two paddles 33 closer together, so that the pins 311 on both sides can be retracted backward synchronously, so that the pins 311 on both sides can be disengaged from the upper limit opening 5 or the lower limit opening 6 at the same time, making it easier to manipulate the paddles 33 to disengage the pins 311 from the upper limit opening 5 or the lower limit opening 6, so that the movable baffle 2 can slide up and down.

[0024] A bottom plate 21 is further provided at the bottom of the movable baffle 2. When the movable baffle 2 is in a high position, the bottom plate 21 limits the movable baffle 2 from sliding further upward, and also further realizes the accurate matching of the latch 311 and the upper limit opening 5, effectively preventing the latch 311 from sliding over the upper limit opening 5.
