[0003] Traditional door locks usually have handles designed as long horizontal rods to improve the ease of operation. However, for families with cats and dogs, if the owner is not at home, they often trigger the handle out of curiosity, causing the door to be opened by mistake, causing unnecessary trouble to the owner, so there is still room for improvement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a door with an anti-misopening function, in which a limit seat is installed on the door body through the sliding card connection between the slide groove and the guide rail, so that the handle can be carded in the limit groove of the limit seat to limit the movement of the handle, thereby preventing the handle from being triggered by mistake.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A door with an anti-misopening function comprises a door body and a handle arranged on the front side of the door body, the handle is in the shape of a horizontal long rod, and a limiting mechanism is arranged on the door body. The limiting mechanism comprises a limiting seat arranged between the handle and the door body and a limiting groove laterally opened on the side of the limiting seat away from the door body for the handle to be engaged, and a horizontal guide rail is arranged on the door body, and a sliding groove is horizontally opened on the side of the limiting seat close to the door body and is slidably engaged with the guide rail so that the limiting seat can slide in the horizontal direction.

[0007] By adopting the above solution, the limit seat can be installed on the door body through the sliding engagement between the slide groove and the guide rail, and the horizontal long rod-shaped handle can be engaged in the limit groove of the limit seat to limit the movement of the handle, thereby preventing the handle from being accidentally touched. When the slide groove is separated from the guide rail, the limit seat can be removed from the door body to restore the active state of the handle, thereby facilitating the user to use the handle.

[0008] Preferably, a limiting member is provided at the opening of the slide groove corresponding to the movable end of the handle.

[0009] By adopting the above solution, the limiting member can limit the maximum stroke of the slide groove on the guide rail, thereby improving the assembly accuracy between the slide groove and the guide rail.

[0010] Preferably, an avoidance groove connected to the guide rail is provided between the limit groove and the sliding groove and on the side close to the limit member, and a clamping groove is provided on the side of the guide rail away from the door body. When the sliding groove is completely slid and clamped on the guide rail, the clamping groove is located in the avoidance groove, and a buckle assembly is provided on the limit member, which is clamped in the clamping groove to prevent the limit seat from sliding along the guide rail.

[0011] By adopting the above scheme, the movement of the slide groove on the guide rail can be effectively restricted by utilizing the snap-fit ​​cooperation between the snap assembly and the slot, so as to lock the limit seat on the guide rail, thereby improving the connection stability between the limit seat and the door body.

[0012] Preferably, the buckle assembly includes a hook buckled in the slot, a first connecting plate arranged on the hook, a second connecting plate arranged on the limiting member, and an elastic member arranged between the first connecting plate and the second connecting plate to drive the first connecting plate to drive the hook to buckle in the slot.

[0018] Preferably, the first gripping member and the second gripping member are bent in opposite directions.

[0019] With the above solution, the bent first gripping piece and the second gripping piece are more convenient for two fingers to bear force, thereby further improving the disassembly efficiency and convenience of the limit seat.

[0020] Preferably, a guiding slope is provided on a side of the hook away from the first connecting plate.

[0021] By adopting the above scheme, when the sliding groove on the limit seat is connected with the guide rail on the door body, the end of the guide rail presses against the guiding slope on the hook, and the guiding slope can overcome the elastic force of the elastic part to drive the hook to lift until the hook is engaged in the groove, thereby improving the installation efficiency and convenience of the limit seat.

[0022] Preferably, mounting plates are provided at both ends of the guide rail, and the mounting plates are fixed to the door body by screws.

[0023] With the above solution, the screw structure is simple, easy to assemble and disassemble, and low in cost. It can stably install the mounting plate on the door body, thereby improving the connection stability between the guide rail and the door body.

[0024] The utility model has a significant technical effect due to the adoption of the above technical solution: through the sliding engagement between the slide groove and the guide rail, the limit seat can be installed on the door body, and the horizontal long rod-shaped handle can be engaged in the limit groove of the limit seat to limit the movement of the handle, thereby preventing the handle from being accidentally touched. When the slide groove is separated from the guide rail, the limit seat can be removed from the door body to restore the active state of the handle, thereby facilitating the user to use the handle.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] like Figures 1 to 4 As shown, a door with an anti-misopening function disclosed in this embodiment includes a door frame 21, a door body 1 pivotally connected to one side of the door frame 21, and a handle 2 arranged on the front side of the door body 1, and the handle 2 is in the shape of a horizontal long rod to facilitate user operation. A limiting mechanism 3 is arranged on the door body 1, and specifically, the limiting mechanism 3 includes a limiting seat 4 arranged between the handle 2 and the door body 1 and a limiting groove 5 horizontally opened on the side of the limiting seat 4 away from the door body 1 for the handle 2 to be engaged. A horizontal guide rail 6 is arranged on the door body 1, and the cross section of the guide rail 6 is trapezoidal. In order to improve the connection stability between the guide rail 6 and the door body 1, mounting plates 19 are arranged at both ends of the guide rail 6, and the mounting plates 19 are fixed to the door body 1 by screws 20. A sliding groove 7 is horizontally opened on the side of the limiting seat 4 close to the door body 1, which is slidably engaged with the guide rail 6 so that the limiting seat 4 can slide in the horizontal direction, and the cross section of the sliding groove 7 is also trapezoidal to adapt to the guide rail 6 and improve the stability of the sliding groove 7 after docking with the guide rail 6.

[0035] like Figure 5 As shown, in order to improve the docking accuracy between the slide slot 7 and the guide rail 6, a limiter 8 is provided at the slide slot 7 corresponding to the opening 22 of the movable end of the handle 2. The limiter 8 is in a long strip shape, and its two ends are respectively overlapped on both sides of the opening 22 of the slide slot 7 and span the opening 22 to form a barrier at the opening 22, thereby limiting the maximum travel of the slide slot 7 on the guide rail 6.

[0036] like Figures 4 to 7As shown, in order to lock the limit seat 4 on the guide rail 6, an avoidance groove 9 connected to the guide rail 6 is provided between the limit groove 5 and the slide groove 7 and on the side close to the limit member 8, and a clamping groove 10 is provided on the side of the guide rail 6 away from the door body 1. When the slide groove 7 is completely slid and clamped on the guide rail 6, the clamping groove 10 is located in the avoidance groove 9, and the limit member 8 is provided with a buckle assembly that is clamped in the clamping groove 10 to prevent the limit seat 4 from sliding along the guide rail 6. Specifically, the buckle assembly includes a hook 12 that is clamped in the clamping groove 10, a first connecting plate 13 provided on the hook 12, a second connecting plate 14 provided on the limit member 8, and an elastic member 15 provided between the first connecting plate 13 and the second connecting plate 14 to drive the first connecting plate 13 to drive the hook 12 to be clamped in the clamping groove 10. The elastic member 15 is preferably a stainless steel spring sheet, and its two ends are respectively connected to the first connecting plate 13 and the second connecting plate 14 as one body.

[0037] like Figure 7 As shown, in order to facilitate the user to release the engagement state between the hook 12 and the slot 10, a first gripping member 16 is extended outward from one side of the first connecting plate 13 away from the hook 12, which responds to external force to drive the first connecting plate 13 to overcome the elastic force of the elastic member 15 and tilt up. The first gripping member 16 is plate-shaped, so that it is convenient for the user to press. In this embodiment, when the first connecting plate 13 tilts up, the hook 12 is separated from the slot 10.

[0038] like Figure 7 As shown, in order to improve the disassembly efficiency and convenience of the limit seat 4, a second gripping member 17 is provided on the outer side of the second connecting plate 14, which is opposite to the first gripping member 16. The second gripping member 17 is also plate-shaped, so as to facilitate force. The first gripping member 16 and the second gripping member 17 are bent in opposite directions, further improving the convenience of operation.

[0039] like Figure 7 As shown, in order to improve the installation efficiency and convenience of the limiting seat 4 , a guiding inclined surface 18 is provided on a side of the hook 12 away from the first connecting plate 13 .

[0040] The specific usage process is as follows:

[0041] When the user needs to go out, the slide groove 7 on the limit seat 4 is slid from left to right and connected to the guide rail 6 of the door body 1. In this process, the guiding inclined surface 18 on the hook 12 can drive the hook 12 to open outward under the pressure of the end of the guide rail 6 until the limit member 8 abuts against the left end of the guide rail 6, and the slot 10 on the guide rail 6 is exposed in the avoidance groove 9 at the bottom of the limit groove 5. At this time, the elastic member 15 drives the first connecting plate 13 to drive the hook 12 to be connected to the slot 10, so as to complete the locking of the slide groove 7 and the guide rail 6, thereby completing the installation of the limit seat 4. In this state, the handle 2 in the shape of a horizontal long rod is just connected to the limit groove 5 of the limit seat 4, so that the limit groove 5 can limit the movement of the handle 2, thereby preventing the handle 2 from being accidentally touched.

[0042] When the handle 2 needs to be used, the first gripping member 16 and the second gripping member 17 are pinched with two fingers to overcome the elastic force of the elastic member 15 to drive the first connecting plate 13 to tilt up, thereby driving the hook 12 to disengage from the slot 10. Then, the first gripping member 16 and the second gripping member 17 are used to pull the limiting member 8 and the limiting seat 4 to the left to drive the slide groove 7 to disengage from the guide rail 6, thereby completing the removal of the limiting seat 4, and then the limiting slot 5 on the limiting seat 4 is separated from the handle 2. At this time, since the handle 2 is no longer restricted by the limiting slot 5, it can be used normally.
