Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a door assembly and a protective cage. Background Technology

[0002] Currently, the doors of existing safety cages can only open inwards and not outwards. For example, a commonly used structure is one that uses spring hinges and spring pin assemblies.

[0003] This structure has a hinge limit in the outward opening direction, which allows the door to open only inwards, and it can also achieve automatic closing and locking.

[0004] However, this structure also has certain drawbacks. For example, if people enter and allow the spring hinges and spring latches to close and lock automatically, the door may fail to close completely, potentially causing people to fall out and resulting in injury or death. Similarly, if the spring latch assembly fails, preventing the door from locking, people may also fall out.

[0005] Therefore, a door assembly and protective cage are needed to at least partially solve the above problems. Utility Model Content

[0057] Now, refer to Figures 1 to 8 Exemplary embodiments according to the present invention will be described in more detail below.

[0058] First preferred embodiment

[0059] refer to Figure 1 , Figure 2 and Figure 3 A first embodiment of the hinged door assembly 100 of this application is shown. In the first embodiment, the hinged door assembly 100 is configured as a single-leaf door structure. That is, the hinged door assembly 100 has only a first door leaf 120.

[0060] The door assembly 100 includes a door frame 110, a first door leaf 120, an automatic locking assembly 140, and a manual locking assembly 130. The first door leaf 120 is pivotally mounted on the door frame 110. The automatic locking assembly 140 is disposed on the first door leaf 120 and has a locked state and an unlocked state. The automatic locking assembly 140 is configured to automatically switch from the unlocked state to the locked state when the first door leaf 120 is closed in the correct position. The manual locking assembly 130 is disposed on the top wall of the first door leaf 120 and has a locked position and an open position. The manual locking assembly 130 is configured to rotate between the locked position and the open position. When the first door leaf 120 is closed in the correct position and the manual locking assembly 130 rotates to the locked position, the manual locking assembly 130 locks the first door leaf 120.

[0061] According to the door assembly 100 of this application, by adding a manual locking component 130 to the automatic locking component 140, an additional step of manual confirmation of the door being closed is added. This ensures that workers can confirm whether the door is closed after entering the door, and can still lock the door even if the manual locking component 130 fails, thus improving safety.

[0062] The automatic locking assembly 140 can be configured as a spring-loaded bolt assembly. In the locked state, the spring-loaded bolt assembly connects to the door frame 110 to lock the first door leaf 120. In the unlocked state, the spring-loaded bolt assembly disengages from the door frame 110, allowing the first door leaf 120 to pivot. The first door leaf 120 and the door frame 110 can be connected by a spring hinge assembly 150, enabling the first door leaf 120 to close automatically.

[0063] The manual locking assembly 130 includes a locking part 132 and a pivot shaft 131. The pivot shaft 131 is disposed on the top wall of the first door leaf 120 and extends along the thickness direction of the first door leaf 120. The locking part 132 rotates about the extending direction of the pivot shaft 131; in other words, one end of the locking part 132 is rotatably connected to the pivot shaft 131, and the other end pivots about the center line of the pivot shaft 131. As a preferred embodiment, the manual locking assembly 130 also includes a handle 133, which can be disposed on the locking part 132 for easy operation by a person.

[0064] The door assembly 100 also includes a mating structure 160, wherein when the manual locking assembly 130 is in the open position, the locking portion 132 of the manual locking assembly 130 is isolated from the mating structure 160. When the manual locking assembly 130 is in the locked position, the locking portion 132 of the manual locking assembly 130 is locked and connected to the mating structure 160.

[0065] In one implementation, when the first door leaf 120 is closed in place, the mating structure 160 is horizontally opposite or substantially opposite to the first door leaf 120. Preferably, when the first door leaf 120 is closed in place, the mating structure 160 is flush with both sides of the first door leaf 120 relative to the thickness direction of the first door leaf 120.

[0066] In one alternative embodiment, the locking part 132 includes two locking walls 135, which are disposed opposite to each other in the thickness direction of the first door leaf 120. When the manual locking assembly 130 is rotated to the locked position, the two locking walls 135 are respectively located on both sides of the mating structure 160 and the first door leaf 120 in the thickness direction of the first door leaf 120, so that the two locking walls 135 restrict the movement of the first door leaf 120 relative to the mating structure 160, thereby forming a lock.

[0067] The locking wall 135 is configured to remain in a position that blocks movement of the first door leaf 120 when the manual locking assembly 130 is rotated to the locked position. Exemplarily, a limiting member can be provided on the door frame 110 or the mating structure 160 to limit further pivoting of the locking wall 135 when it has pivoted to the locked position. Alternatively, a damping structure can be provided on the pivot axis 131 so that the locking wall 135 has resistance during pivoting, allowing it to remain in a fixed position without external action, but pivoting under external action.

[0068] Preferably, the locking part 132 further includes a connecting plate 134, which is connected between the two locking walls 135. When the manual locking assembly 130 is rotated to the locked position, the connecting plate 134 abuts against the top wall of the mating structure 160 and the top wall of the first door leaf 120. Thus, the locking position is maintained by the connecting plate 134.

[0069] In the first embodiment, the first door leaf 120 has a pivot side pivotally connected to the door frame 110 and a free side opposite to the pivot side. The mating structure 160 is configured as a first limiting protrusion 111, which is connected to the end of the door frame 110 opposite to the pivot side of the first door leaf 120. In other words, when the first door leaf 120 is closed, the first limiting protrusion 111 is close to the free side of the first door leaf 120.

[0070] The first door leaf 120 includes a door leaf body 122 and a second limiting protrusion 121. The second limiting protrusion 121 is connected to the top wall of the door leaf body 122 and is located at one end of the door leaf body 122 near the free side. A manual locking assembly 130 is rotatably disposed on the top wall of the second limiting protrusion 121.

[0071] Preferably, the first limiting protrusion 111 extends a predetermined distance in the direction pointing to the pivot side; in other words, the first limiting protrusion 111 protrudes from the surface of the door frame 110, so that when the first door leaf 120 is closed in place, the door leaf body 122 is located below the first limiting protrusion 111. The top wall of the first limiting protrusion 111 and the top wall of the second limiting protrusion 121 can be horizontally aligned or substantially horizontally aligned, so that the connecting plate 134 of the locking part 132 can simultaneously and smoothly conform to the top walls of both the first limiting protrusion 111 and the second limiting protrusion 121.

[0072] As a preferred embodiment, such as Figure 3 As shown, the first limiting protrusion 111 can be higher than the second limiting protrusion 121, such that the top wall of the first limiting protrusion 111 is higher than the top wall of the second limiting protrusion 121, and the bottom wall of the first limiting protrusion 111 is lower than the bottom wall of the second limiting protrusion 121. This allows the pivoting side of the first door leaf 120 to pivot smoothly to below the first limiting protrusion 111 without obstruction when the first door leaf 120 is closed.

[0073] Second preferred embodiment

[0074] Figure 4 , Figure 5 , Figure 6 and Figure 7 A second preferred embodiment of this application is shown. This second preferred embodiment is a variation of the first preferred embodiment. Except for its double-door configuration, the door assembly 200 of the second preferred embodiment has a similar structure and / or construction to the door assembly 100 of the first preferred embodiment. Therefore, elements having substantially the same function as those in the first preferred embodiment will be denoted by the same numbers and, for the sake of brevity, will not be described in detail and / or illustrated further.

[0075] In this embodiment, the door assembly 200 includes a first door leaf 120, a second door leaf 221, an automatic locking assembly 140, and a manual locking assembly 130. The second door leaf 221 cooperates with the first door leaf 120 to construct the door assembly 200 as a double-door structure.

[0076] The first door leaf 120 and the second door leaf 221 are pivotally connected to the door frame 110, respectively. Alternatively, both the first door leaf 120 and the second door leaf 221 can be pivotally mounted on the door frame 110, for example, both the first door leaf 120 and the second door leaf 221 are pivotally connected to the door frame 110 via a spring hinge assembly 150. An automatic locking assembly 140 is disposed on at least one of the first door leaf 120 and the second door leaf 221. Exemplarily, when the automatic locking assembly 140 is disposed on the first door leaf 120 and is in a locked state, the automatic locking assembly 140 is connected to the second door leaf 221, thereby locking both the first door leaf 120 and the second door leaf 221 together.

[0077] Both the first door leaf 120 and the second door leaf 221 have a pivot side that is pivotally connected to the door frame 110 and a free side that is opposite to the pivot side. When the door assembly 200 is closed, the free sides of the first door leaf 120 and the free sides of the second door leaf 221 are opposite to each other and are approximately flush.

[0078] The manual locking assembly 130 is provided on the first door leaf 120 or the second door leaf 221. For example, in Figures 4 to 7 In the illustrated embodiment, the manual locking assembly 130 is located at one end of the first door leaf 120 near its own free side, while the top region of the free side of the second door leaf 221 forms a mating structure 160. In this embodiment, no second limiting protrusion is provided on the first door leaf 120, and the manual locking assembly 130 is directly provided on the top wall of the first door leaf 120.

[0079] Therefore, as Figure 6 and Figure 7 As shown, when the manual locking assembly 130 is pivoted to the locked position, the two locking walls 135 of the locking part 132 are located on the inner and outer sides of the free side of the first door leaf 120 and the free side of the second door leaf 221, respectively.

[0080] refer to Figure 8 In another aspect, this application provides a protective cage 10, which is generally formed into a cage shape by a frame body 13. It has an end face 11 and a side face 12, both of which are preferably provided with door assemblies to facilitate worker access. The door frame 110 of the door assembly is provided on the frame body 13.

[0081] The end face 11 has a shorter length, which allows for the installation of the single-door hinged door assembly 100 of the first embodiment described above. The side face 12 has a longer length, which allows for the installation of the double-door hinged door assembly 200 of the second embodiment described above.

[0082] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Features described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.

[0083] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are only for illustrative purposes. This utility model is not limited to the above embodiments. Many variations and modifications can be made based on the teachings of this utility model, and all such variations and modifications fall within the scope of protection claimed by this utility model.
