Description

Technical Field

[0001] The utility model relates to the field of cage door, in particular to a cage door which can maintain an open and closed state. Background Art

[0002] The cage is a vertical transportation tool used in manufacturing companies or construction sites to transport people or goods up and down. The floor door is one of the structures of the cage. The floor door can be opened and closed laterally or longitudinally to open or close the cage, making it easier for people or goods to enter and exit the cage.

[0003] During the lifting process of the cage, the floor door of the cage needs to be locked to prevent the personnel in the cage from opening the floor door by mistake and causing safety hazards. The prior art, for example, has the application (patent) number: CN202111019048.3, and its name is a floor door and elevator for an elevator. In order to lock the floor door, the prior art generally uses a limiting mechanism to abut against the top of the floor door when the floor door is closed, so that the door body cannot be opened. When the floor door is unlocked, the limiting mechanism still has a tendency to flip downward under the action of gravity. During the door opening process, the limiting mechanism will scrape against the top of the floor door. At the same time, if the door body is opened at an angle of more than 90°, the limiting mechanism will naturally flip down under the action of gravity, making the door body unable to close.

[0004] The purpose of the present invention is to design a cage door that can maintain an open or closed state in view of the above-mentioned problems in the prior art. Utility Model Content

[0005] In view of the problems existing in the above-mentioned prior art, the utility model provides a cage door which can maintain an open and closed state, and can effectively solve at least one problem existing in the above-mentioned prior art.

[0010] A state-maintaining assembly is arranged at a position above the door frame corresponding to the door body, and the state-maintaining assembly includes a T-shaped rod, and the intersection of the T-shaped rod is hinged to the door frame. When the door body is opened, the door body drives the transverse portion of the T-shaped rod to flip the T-shaped rod so that the transverse portion of the T-shaped rod supports the limit assembly. When the door body is closed, the door body drives the vertical portion of the T-shaped rod to separate the transverse portion of the T-shaped rod from the limit assembly.

[0011] The clamping assembly is arranged at the intersection of the T-shaped rods, and the clamping assembly is used to clamp the T-shaped rods so that the T-shaped rods can maintain the support or be separated from the limiting assembly.

[0012] Furthermore, a rotating wheel is provided on the transverse portion of the T-shaped rod.

[0013] Furthermore, the limit baffle assembly includes a limit baffle, a limit member, and a driving member. The limit baffle is hinged on the top of the door body, and the driving member is used to drive the limit member to block or release the limit baffle. When the limit baffle is naturally flipped down by gravity and blocked by the limit member, the limit baffle limits the door body from opening. When the limit baffle is released by the limit member, the limit baffle releases the door body.

[0014] Furthermore, a guide groove is provided at a position of the limit baffle corresponding to the T-shaped rod, and a transverse portion of the T-shaped rod supports the limit assembly through the guide groove.

[0015] Furthermore, the limiting member is a rotating rod disposed above the limiting baffle, a baffle is disposed on the side of the rotating rod, and the baffle can prevent the limiting baffle from turning up, and the driving member is used to drive the rotating rod to rotate.

[0022] The elastic member is arranged on the movable seat so that the movable seat has a movement tendency toward the fixed seat.

[0023] Therefore, the utility model provides the following effects and / or advantages:

[0024] The present application uses a state holding component to always support the door body on the limit component when the door body is opened, so that the limit component remains in an unlocked state and does not flip down to hinder the opening and closing of the door body.

[0025] The present application uses a specially designed clamping component to maintain the state of the state holding component in a supporting state or an unlocked state after the state holding component is flipped 90°.

[0026] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the invention.

[0033] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0034] Embodiment 1

[0035] refer to Figure 1-5 , a cage door that maintains an open and closed state, comprising:

[0036] Door frame 1 and door body 2;

[0037] A limiting component 3, the limiting component 3 is arranged above the door frame 1, and the limiting component 3 is used to limit or release the door body 2;

[0038] A state-maintaining component 4 is arranged at a position above the door frame 1 corresponding to the door body 2, and the state-maintaining component 4 includes a T-shaped rod 401, and the intersection of the T-shaped rod 401 is hinged to the door frame 1. When the door body 2 is opened, the door body 2 drives the transverse part of the T-shaped rod 401 so as to flip the T-shaped rod 401 so that the transverse part of the T-shaped rod 401 supports the limiting component 3. When the door body 2 is closed, the door body 2 drives the vertical part of the T-shaped rod 401 so as to separate the transverse part of the T-shaped rod 401 from the limiting component 3.

[0039] The clamping assembly 5 is disposed at the intersection of the T-shaped rod 401 , and is used to clamp the T-shaped rod 401 so that the T-shaped rod 401 remains supported or separated from the limiting assembly 4 .

[0040] refer to Figure 3 In this embodiment, when the stopper assembly 3 releases the door body 2, the door body 2 can be opened freely. When the door body 2 is closed, the transverse portion of the T-shaped rod 401 faces downward. During the process of opening the door body 2, the door body 2 drives the transverse portion of the T-shaped rod 401 to flip outward, thereby forming a Figure 3 In the state shown, the lateral portion of the T-bar 401 is supported on the limit assembly 3, as shown in FIG. Figure 1 As shown, the limiting assembly 3 is in a state of completely releasing the door body 2. When the door body 2 is closed, the door body 2 drives the vertical portion of the T-shaped rod 401 to flip inward, so that the T-shaped rod 401 releases the limiting assembly 3.

[0041] The clamping assembly 5 is used to clamp the T-shaped bar 401 so that the T-shaped bar 401 can remain in the state of being driven by no external force. Figure 3 The state shown in the figure makes the limiting assembly 3 always keep a completely released state, and there is no friction with the limiting assembly 3 during the opening process of the door body 2.

[0042] Furthermore, a rotating wheel 402 is provided on the transverse portion of the T-shaped bar 401 .

[0043] Furthermore, the limiting assembly 3 includes a limiting baffle 301, a limiting member 302, and a driving member 303. The limiting baffle 301 is hinged on the top of the door body 2. The driving member 303 is used to drive the limiting member 302 to block or release the limiting baffle 301. When the limiting baffle 301 is naturally flipped down by gravity and blocked by the limiting member 302, the limiting baffle 301 limits the door body 2 to open. When the limiting baffle 301 is released by the limiting member 302, the limiting baffle 301 releases the door body 2.

[0044] Further, refer to Figure 4The limiting member 302 is a rotating rod disposed above the limiting baffle 301, and a baffle is disposed on the side of the rotating rod, which can prevent the limiting baffle 301 from flipping up, and the driving member 303 is used to drive the rotating rod to rotate.

[0045] Furthermore, the driving member 303 includes a push plate 3032, a driving cylinder 3033, and an opening and closing connecting rod 3031. The push plate 3032 is driven by the corresponding driving cylinder 3033. One end of the opening and closing connecting rod 3031 is connected to the rotating rod 302. The other end of the opening and closing connecting rod 3031 is driven by the push plate 3032. When the opening and closing connecting rod 3031 is brought together, it drives the rotating rod to prevent the limit baffle 301 from flipping up.

[0046] In this embodiment, the opening and closing connecting rod 3031 is a herringbone structure, one of the bottom ends of the herringbone structure is set on the rotating rod, and the other bottom end of the herringbone structure is cooperated with the roller and the push plate 3032. When the push plate 3032 is extended, the roller is squeezed and moves upward, and the herringbone structure opens, driving the rotating rod to rotate, so that the baffle releases the limit baffle 301.

[0047] Further, refer to Figure 5 The position of the limiting baffle 301 corresponding to the T-bar 401 is provided with a guide groove 3011 , and the transverse portion of the T-bar 401 supports the limiting assembly 3 through the guide groove 3011 .

[0048] Furthermore, the door frame 1 is provided with an avoidance groove 101 .

[0049] Furthermore, a linkage plate 201 is provided at the top of the door body 2 corresponding to the position of the state maintaining component 4 .

[0050] In this embodiment, since the top of the door body 2 may not be in direct contact with the state maintaining component 4 , a linkage plate 201 may be additionally provided to increase the height of the top of the door body 2 .

[0051] Furthermore, the clamping assembly 5 comprises:

[0052] A fixing seat 501 is fixedly disposed on the door frame 1, and the intersection of the T-shaped rod 401 is hinged to the fixing seat 501;

[0053] The movable seat 502 can be movably arranged toward the fixed seat 501, and the movable seat 502 is provided with a cross-shaped groove;

[0054] The elastic member 503 is disposed on the movable seat 502 so that the movable seat 502 has a movement tendency toward the fixed seat 501 .

[0055] like Figure 3As shown, the fixed seat 501 serves as the intersection of the T-shaped rod 401. In the absence of external force, the elastic member 503 drives the movable seat 502 to clamp the T-shaped rod 401, so that the T-shaped rod 401 is in the cross-shaped groove and maintains its position. When the T-shaped rod 401 is driven by the door body 2, the T-shaped rod 401 can push the movable seat 502 open and rotate to a certain angle.
