[0034] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0035] refer to Figure 1 As shown, an embodiment of this application provides a door bolt structure 100, which includes a bolt body 110, a bolt seat 120, and a movable component 130.
[0036] Specifically, in combination Figure 2 and Figure 3As shown, the bolt body 110 includes a first limiting part 111 and a second limiting part 112, which are respectively disposed at opposite ends of the bolt body 110. The bolt seat 120 defines a through groove 121, through which the bolt body 110 passes, and the bolt body 110 is movably connected to the bolt seat 120. The movable component 130 is movably installed on the door body 200. Correspondingly, the bolt body 110, bolt seat 120, and movable component 130 of the door bolt structure 100 cooperate to realize the function of opening and closing the door body 200. The structure is compact, so that the door bolt structure 100 can realize the self-locking function or the self-locking function of the door body 200. It is easy to use and thus improves the use effect of the door bolt structure 100.
[0037] like Figure 3 and Figure 4 As shown, the bolt 110 has at least a first position and a second position. When the bolt 110 is in the first position, the first limiting part 111 engages with the slot of the through groove 121, and the second limiting part 112 extends toward the movable component 130 to limit the door body 200. When the bolt 110 is in the second position, the movable component 130 abuts against the second limiting part 112 and drives the second limiting part 112 to retract, so that the second limiting part 112 separates from the door body 200. The bolt 110 can move between the first position and the second position. When the bolt 110 moves to the first position under the action of gravity, the second limiting part 112 extends to limit and lock the door body 200. The through groove 121 of the bolt seat 120 plays a limiting role for the first limiting part 111, so as to determine that the bolt seat 120 is in the first position after moving into place. In order to release the locking of the door bolt structure 100, the movable component 130 abuts against the second limiting part 112. When the movable component 130 moves, it drives the second limiting part 112 to retract away from the door body 200. When the bolt 110 moves to the second position, the second limiting part 112 retracts, allowing the door body 200 to open freely.
[0038] It is understandable that the door body 200 mainly includes the door leaf, which moves relative to the door to open or close the door, and rotates with the door frame through hinges; the door frame is the load-bearing and positioning structure of the door, and includes the side frame, threshold, etc.
[0039] like Figure 1 and Figure 2As shown, the door bolt structure 100 has a first direction X and a second direction Y, wherein the first direction X and the second direction Y are perpendicular to each other. For example, the first direction X refers to the width direction of the door bolt structure 100, and the second direction Y refers to the height direction of the door bolt structure 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the door bolt structure 100 and should not be construed as limitations on this application.
[0040] In one embodiment, alternatively, such as Figure 3 As shown, the second limiting part 112 extends to form a bent part 1121. The bending angle of the bent part 1121 is θ, which satisfies: 45°≤θ<90°, that is, the bending angle θ of the bent part 1121 is less than 90°, so that the bending angle θ of the bent part 1121 is an acute angle structure, avoiding the bending angle of the bent part 1121 being too large and affecting the relative movement of the movable component 130 and the normal locking of the door 200. In addition, the bending angle θ of the bent part 1121 is greater than or equal to 45°, so that when the movable component 130 contacts the second limiting part 112, it has sufficient contact area and tilt angle to drive the bolt 110 to move, so that the bolt 110 can achieve the purpose of locking or opening the door 200.
[0041] In one embodiment, alternatively, referencing Figure 1 and Figure 2 As shown, the bending portion 1121 is located on the side of the bolt body 110 away from the door frame. In other words, the bending portion 1121 extends and bends in a direction away from the door frame, so that the bending portion 1121 can cooperate with the door body 200 to achieve the purpose of locking and unlocking the door.
[0042] In one embodiment, optionally, combining Figure 3 and Figure 4 As shown, when the movable component 130 moves relative to the door bolt 100 along the first direction X, it can drive the bolt body 110 to move relative to the door bolt 100 along the second direction Y. The first direction X and the second direction Y are perpendicular to each other. When the movable component 130 abuts against the bending part 1121 and drives the bending part 1121 to move, the movable component 130 moves along the width direction of the door bolt structure 100, and the bending part 1121 moves relative to the height direction of the door bolt structure 100. The bending part 1121 separates from the door body 200, releasing the locking function of the door body 200, thereby realizing the function of opening the door through the movable component 130.
[0043] In summary, the bolt body 110, bolt seat 120, and movable component 130 of the door bolt structure 100 cooperate to realize the function of opening and closing the door. The bolt body 110 can move between a first position and a second position. When the bolt body 110 moves to the first position under the action of gravity, the second limiting part 112 extends to limit and lock the door body 200. The through groove 121 of the bolt seat 120 limits the first limiting part 111 to determine whether the bolt seat 120 is in the first position after moving into place. When the door bolt structure 100 is released from its lock, the movable component 130 abuts against the second limiting part 112. When the movable component 130 moves, it causes the second limiting part 112 to retract and move away from the door body 200. When the bolt body 110 moves to the second position, the second limiting part 112 retracts, allowing the door body 200 to open freely. The structure is ingenious, so that the door bolt structure 100 can realize the self-locking function or the self-locking function of the door body 200. It is relatively simple to use, thereby improving the use effect of the door bolt structure 100.
[0044] refer to Figures 1 to 3 As shown, an embodiment of this application provides another door bolt structure 100, which includes a bolt body 110, a bolt seat 120, and a movable component 130.
[0045] Specifically, in combination Figure 2 and Figure 3As shown, the bolt body 110 includes a first limiting part 111 and a second limiting part 112, which are respectively disposed at opposite ends of the bolt body 110. The bolt seat 120 defines a through groove 121, through which the bolt body 110 passes, and the bolt body 110 is movably connected to the bolt seat 120. The movable component 130 is movably installed on the door body 200. Correspondingly, the bolt body 110, bolt seat 120, and movable component 130 of the door bolt structure 100 cooperate to realize the function of opening and closing the door body 200. The structure is compact, so that the door bolt structure 100 can realize the self-locking function or the self-locking function of the door body 200, which is simple to use and thus improves the use effect of the door bolt structure 100. The bolt body 110 has at least a first position and a second position. When the bolt 110 is in the first position, the first limiting part 111 engages with the slot of the through groove 121, and the second limiting part 112 extends toward the movable component 130 to limit the door 200. When the bolt 110 is in the second position, the movable component 130 abuts against the second limiting part 112 and drives the second limiting part 112 to retract, so that the second limiting part 112 separates from the door body 200. The bolt 110 can move between the first position and the second position. When the bolt 110 moves to the first position under the action of gravity, the second limiting part 112 extends to limit and lock the door body 200. The through groove 121 of the bolt seat 120 plays a limiting role for the first limiting part 111, so as to determine that the bolt seat 120 is in the first position after moving into place. In order to release the locking of the door bolt structure 100, the movable component 130 abuts against the second limiting part 112. When the movable component 130 moves, it drives the second limiting part 112 to retract away from the door body 200. When the bolt 110 moves to the second position, the second limiting part 112 retracts, allowing the door body 200 to open freely.
[0046] In one embodiment, alternatively, such as Figure 3As shown, the second limiting part 112 extends to form a bent part 1121. The bending angle of the bent part 1121 is θ, which satisfies: 45°≤θ<90°, that is, the bending angle θ of the bent part 1121 is less than 90°, so that the bending angle θ of the bent part 1121 is an acute angle structure, avoiding the bending angle of the bent part 1121 being too large and affecting the relative movement of the movable component 130 and the normal locking of the door 200. In addition, the bending angle θ of the bent part 1121 is greater than or equal to 45°, so that when the movable component 130 contacts the second limiting part 112, it has sufficient contact area and tilt angle to drive the bolt 110 to move, so that the bolt 110 can achieve the purpose of locking or opening the door 200. For example, the bending angle θ of the bending portion 1121 can be any value between 45° and 90°. For instance, the bending angle θ of the bending portion 1121 can be 50°, 55°, 65°, 75°, 85°, etc., which will not be described in detail here.
[0047] In one embodiment, alternatively, referencing Figure 1 and Figure 2 As shown, the bent portion 1121 is located on the side of the bolt body 110 away from the door frame. In other words, the bent portion 1121 extends and bends in a direction away from the door frame, so that the bent portion 1121 can cooperate with the door body 200 to achieve the purpose of locking and unlocking the door.
[0048] In one embodiment, optionally, combining Figure 3 and Figure 4 As shown, when the movable component 130 moves relative to the first direction X, it can drive the bolt body 110 to move relative to the second direction Y. The first direction X and the second direction Y are perpendicular to each other. When the movable component 130 abuts against the bending part 1121 and drives the bending part 1121 to move, the movable component 130 moves along the width direction of the door bolt structure 100, and the bending part 1121 moves relative to the height direction of the door bolt structure 100. The bending part 1121 separates from the door body 200, releasing the locking function of the door body 200, thereby realizing the function of opening the door through the movable component 130.
[0049] Optionally, refer to Figure 2As shown, the movable component 130 includes a movable element 131 and an elastic element 132. The door body 200 has a through hole 210, through which the movable element 131 passes. The elastic element 132 is sleeved on the movable element 131 and abuts against the door body 200 and the movable element 131. The movable element 131 is installed on the door body 200 through the through hole 210. When the movable element 131 moves relative to the door body 200, it causes the bolt 110 to move, separating the bent portion 1121 from the door body 200 for easy opening. The movable element 131 can return to its initial state under the action of the elastic element 132, and the bolt 110 will not affect or obstruct the return of the movable element 131. For example, the elastic element 132 is a return spring. A return spring is a functional element that stores and releases mechanical energy through elastic deformation and can autonomously restore its initial geometric shape after the external load is removed.
[0050] Optionally, refer to Figure 4 As shown, when the bolt 110 is in the second position, the contact position between the movable member 131 and the second limiting part 112 is located at the door gap, achieving the purpose of separating the second limiting part 112 of the bolt 110 from the door body 200. In the second position, it facilitates free opening and closing of the door body 200 and prevents the second limiting part 112 from causing obstruction, thus achieving better technical results. It can be understood that the door gap is located in the gap between the door body 200 and the door frame.
[0051] In one embodiment, optionally, combining Figure 2 and Figure 3 As shown, there are multiple bolt seats 120, which are spaced apart along the second direction Y. Each bolt seat 120 defines a through slot 121. That is, the multiple bolt seats 120 are spaced apart along the height direction of the bolt structure 100, so that the through slots 121 of the multiple bolt seats 120 are all used to install the bolt body 110, regulating and restricting the movement path of the bolt body 110, and preventing the bolt body 110 from shifting or misaligning during relative movement. Exemplarily, there are two bolt seats 120, which are used to fix and limit the bolt body 110, respectively.
[0052] Optionally, such as Figure 2 As shown, the thimble seat 120 is located between the first limiting part 111 and the second limiting part 112. The first limiting part 111 and the second limiting part 112 of the thimble body 110 are respectively limited by the thimble seat 120 to prevent the thimble body 110 from dislodging from the thimble seat 120 during the movement of the first limiting part 111 or the second limiting part 112, so as to facilitate the normal use of the thimble body 110.
[0053] Optionally, combined Figure 3 and Figure 4 As shown, one of the bolt bodies 110 passes through multiple through slots 121 in sequence. In other words, one bolt body 110 can pass through multiple through slots 121 of bolt seats 120 in sequence, so that the through slots 121 of multiple bolt seats 120 can jointly regulate and limit the bolt body 110, thereby improving the user experience.
[0054] An embodiment of this utility model also provides a door bolt system, including the bolt structure 100 in the above embodiments. The door bolt system including the bolt structure 100 has all the beneficial effects of the bolt structure 100, which will not be described in detail here.
[0055] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0056] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
