Abstract
Description
Technical Field
[0001] This utility model relates to the field of container security door technology, and in particular to a container security door with an embedded handle. Background Technology
[0002] Recently, a type of security door with a function for receiving goods or packages has appeared on the market and has become very popular. For example, Chinese patent CN215369515U discloses a security door with a package receiving and delivery function. It mainly consists of a box or cabinet for receiving goods installed on the security door, with the door of the box or cabinet nested inside the security door body. This type of security door is equipped with both a security door lock and a cabinet door lock to lock the security door itself and the cabinet door respectively. The cabinet door lock can be controlled by the homeowner's mobile phone, thus enabling the effective receipt of goods or packages. While ensuring security and theft prevention, it also allows for convenient and quick package receipt even when no one is home.
[0003] Conventional security doors have their outer handles mounted on the door body. Therefore, modern container security doors also typically have their outer handles designed onto the security door itself. To facilitate opening and closing the container door, handles are often installed on the container door itself, or the door is designed with a push-to-open mechanism. However, this design presents several problems: First, installing handles on both the security door and the container door increases production costs and is aesthetically unappealing and cumbersome. Second, if the container door has a push-to-open mechanism, this structure is prone to damage, making the door difficult to open. Third, regardless of whether a handle is prominently displayed on the security door or the container door, the container security door, being thicker than a conventional security door, appears significantly thicker, negatively impacting the user's experience. Utility Model Content
[0004] In view of this, this utility model proposes a container security door with an embedded handle to solve the problem of unreasonable handle design on current container security doors.
[0005] The technical solution of this utility model is implemented as follows: This utility model provides a container anti-theft door with an embedded handle, including a door frame, a door body, a container door and a protruding strip; the door frame is fitted inside the room entrance; the door body is closed inside the door frame and has a cabinet cavity on the side facing the outside; the container door is closed on the cabinet cavity; the protruding strip is provided on the container door, with both ends of the protruding strip extending vertically, and a groove is provided on the protruding strip and an embedded handle is provided in the groove.
[0006] Based on the above technical solutions, preferably, it also includes a first hinge connector and a second hinge connector; the first hinge connector is disposed between one vertical side of the door body and the inner wall of the door frame, so that the door body swings horizontally to open and close relative to the door frame; the second hinge connector is disposed between the side of the container door near the hinge connection part of the door body and the inner wall of the container cavity, so that the container door swings horizontally to open and close relative to the door body.
[0007] More preferably, the raised strip is located on the outer wall of the container door on the side away from the hinge connection of the container door.
[0008] In a further preferred embodiment, a notch is provided on the side of the door body where the first hinge connector is located, and the first hinge connector is installed in the notch, so that the outer wall of the door frame is flush with the outer wall of the door body.
[0009] In a further preferred embodiment, a groove is provided on the outer wall of the door body, and a container door is installed in the groove, so that the outer wall of the door body is flush with the outer wall of the container door.
[0010] In a further preferred embodiment, the portion of the door body located between the notch and the groove forms a protrusion, and the second hinge connector is embedded in the protrusion. A connecting rod connects the second hinge connector to the side of the container door, allowing the container door to rotate circumferentially around the protrusion.
[0011] Even more preferably, the side of the protrusion closest to the container door is set as a slope.
[0012] More preferably, it also includes a handle, which is disposed on the surface of the door body facing the interior, and is located on the side of the door body away from the first hinge connector. The handle is a horizontal handle.
[0013] Based on the above technical solutions, preferably, the raised strip is located in the middle of the long side of the container door.
[0014] Based on the above technical solutions, preferably, the length of the convex strip is not less than two-thirds of the length of the container door.
[0015] The container security door with an embedded handle of this utility model has the following advantages over the prior art:
[0016] (1) This utility model provides a raised strip on the container door and a hidden handle in the groove of the raised strip. The raised strip can clearly show the position of the handle to the user, making it convenient for the user to identify the position of the handle. At the same time, the hidden handle avoids the problem of the security door becoming significantly thicker in appearance. The hidden handle is also not easy to be damaged or fail. In addition, the handle in the raised strip on the container door can be used for opening and closing the security door and the container door at the same time, without affecting the normal use of the container security door.
[0017] (2) The handle on the inside of the security door is designed as a horizontal handle. Since the security door of the container is thicker than the conventional security door, the inner edge of the door body will be very close to the inside of the door frame when the door body is opened and closed. If the handle on the inside of the security door is designed as a vertical handle, the fingers may rub against the inside of the door frame and get injured when the person operates the vertical handle. However, the use of a horizontal handle can effectively avoid the problem of the person's hand rubbing against the inside of the door frame. Attached Figure Description

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0029] like Figure 1 As shown, combined with Figure 2 and Figure 5 The present invention relates to a container security door with an embedded handle, comprising a door frame 1, a door body 2, a container door 3, and a raised strip 4.
[0030] Door frame 1 is installed inside the room entrance. Door frame 1 is a metal frame.
[0031] The door body 2 is enclosed within the door frame 1 and has a cabinet cavity 201 on the side facing the outside. One long side of the door body 2 is hinged to the door frame 1.
[0032] The container door 3 is closed on the container cavity 201. One long side of the container door 3 is hinged to the inner wall of the container cavity 201.
[0033] A raised strip 4 is installed on the container door 3, extending vertically at both ends. The raised strip 4 has a groove with a recessed handle inside. By installing a handle on the container door 3, the opening and closing of both the container door 3 and the door body 2 can be operated simultaneously. Specifically, when the door body 2 is locked and the container door 3 is open, pulling the hidden handle inside the raised strip 4 will open the container door 3; conversely, when the door body 2 is open and the container door 3 is locked, pulling the hidden handle inside the raised strip 4 will open the door body 2. This eliminates the need for handles on both the door body 2 and the container door 3, which would be cumbersome and unsightly. Although the raised strip 4 protrudes slightly outwards from the surface of the security door, the groove within it allows for a less noticeable increase in the overall thickness of the raised strip 4, preventing a significant increase in the perceived thickness of the security door. Furthermore, the design of the raised strip 4 allows the homeowner to quickly and clearly identify the location of the hidden handle, serving as a prominent marker. Furthermore, if a recess is directly created on the container door 3 and a hidden handle is installed without involving the protruding strip 4, on the one hand, this would create an inwardly recessed area on the container door 3, compressing the accommodating space of the container cavity 201; on the other hand, the completely flat surface of the security door, where the handle is not visible, would feel abrupt to the user, and in fact, it does not meet the requirements of excellent ergonomic design. The hidden handle can be a fixed, immovable structure, or it can be a flexible, outward-folding, and spring-back structure.
[0034] exist Figure 4In a preferred embodiment shown, the device further includes a first hinge connector 5 and a second hinge connector 6.
[0035] The first hinge connector 5 is disposed between one vertical side of the door body 2 and the inner wall of the door frame 1, allowing the door body 2 to swing horizontally open and close relative to the door frame 1. The first hinge connector 5 generally includes two connecting plates and a rotatable shaft pin disposed between the two connecting plates. The two connecting plates are respectively disposed on the vertical side of the door body 2 and the inner wall of the door frame 1.
[0036] The second hinge connector 6 is located between the side of the container door 3 near the hinge connection point of the door body 2 and the inner wall of the container cavity 201, allowing the container door 3 to swing open and close horizontally relative to the door body 2. The second hinge connector 6 generally includes two connecting plates and a rotatable shaft pin located between the two connecting plates. The two connecting plates are respectively located on the vertical side of the container door 3 and the inner wall of the container cavity 201. The hinge connector enables the door body 2 or the container door 3 to swing open and close.
[0037] exist Figure 3 In a preferred embodiment shown, the protrusion 4 is located on the outer wall of the container door 3, away from the hinge connection. Therefore, the protrusion 4 is positioned far from the hinge connection of the door body 2 or the container door 3, making it easier for the operator to open and close the door body 2 or the container door 3 by pulling the handle inside the protrusion 4. Since the security door is relatively heavy, and the protrusion 4 is located on the movable container door 3, with the lock inside the protrusion 4 very close, when the container door 3 is locked to the door body 2, pulling the handle inside the protrusion 4 will not subject the locking connection between the container door 3 and the door body 2 to a large relative force, thus avoiding damage to the lock body of the container door 3. Furthermore, the protrusion 4's proximity to the lock body of the container door 3 or the door body 2 not only better meets the aesthetic requirements of human visual perception.
[0038] exist Figure 4 In a preferred embodiment shown, a notch 202 is provided on the side of the door body 2 where the first hinge connector 5 is located. The first hinge connector 5 is installed within the notch 202, making the outer wall of the door frame 1 flush with the outer wall of the door body 2. Conventional security door hinges typically protrude outwards, but this design makes the door appear significantly thicker, especially for container security doors which are thicker than conventional security doors. Therefore, by installing the first hinge connector 5 within the notch 202, the installation position of the first hinge connector 5 is moved back a certain distance towards the interior, preventing it from protruding and making the container security door more aesthetically pleasing. Furthermore, the retraction of the first hinge connector 5 towards the interior places its installation position closer to the middle of the security door's thickness, resulting in a more rational load-bearing design.
[0039] exist Figure 6In a preferred embodiment shown, a groove 203 is provided on the outer wall of the door body 2, and the container door 3 is installed in the groove 203, so that the outer wall of the door body 2 is flush with the outer wall of the container door 3, making the container security door more aesthetically pleasing.
[0040] exist Figure 6 In a preferred embodiment shown, the portion of the door body 2 located between the notch 202 and the groove 203 forms a protrusion 21. A second hinge connector 6 is embedded in the protrusion 21, and a connecting rod 61 connects the second hinge connector 6 to the side of the container door 3, allowing the container door 3 to rotate circumferentially around the protrusion 21. Since the second hinge connector 6 is embedded in the protrusion 21, if the connecting plate of the second hinge connector 6 were directly installed on the side of the container door 3, the container door 3 would be blocked by the protrusion 21 when it swings outward to open. Therefore, by extending the rotation radius of the container door 3 through the connecting rod 61, the container door 3 can be opened and closed outward without being blocked by the protrusion 21.
[0041] exist Figure 4 In a preferred embodiment shown, the side of the protrusion 21 near the container door 3 is provided as a slope 204. The slope 204 makes the corner of the protrusion 21 form a notch design, which makes way for the container door 3 to swing outward to open and close, so that the container door 3 can have a larger opening and closing angle.
[0042] exist Figure 7 and Figure 8 In a preferred embodiment shown, a handle 7 is also included. The handle 7 is disposed on the surface of the door body 2 facing the interior, and is located on the side of the door body 2 away from the first hinge connector 5. The handle 7 is a horizontal handle. The handle 7 is generally connected to the door lock cylinder shaft of the door body 2, and the security door can be opened from the inside by pressing down on the handle 7. See reference. Figure 8 As shown in Figure b, if a vertical handle is used, the container security door is thicker than a regular security door due to the container inside. The thickness of the container security door extends inwards, which means that when the door body is opened and closed, the inner edge of the door is very close to the inner side of the door frame during the swinging motion. If the handle on the inside of the security door is designed as a vertical handle, which is usually close to the edge of the door, when a person operates the vertical handle, their fingers may rub against the inner side of the door frame during the swinging motion, causing injury. However, using the horizontal handle 7 shown in Figure a, the horizontal design of handle 7 restricts the person's hand from getting close to the edge of the door without hindering the person from pulling the security door open and close, thus effectively avoiding the problem of the person's hand rubbing against the inner side of the door frame.
[0043] exist Figure 1 In a preferred embodiment shown, the protrusion 4 is located in the middle of the long side of the container door 3, so that the force applied to the security door when the handle is pulled is more reasonably distributed.
[0044] exist Figure 1In a preferred embodiment shown, the length of the protrusion 4 is not less than two-thirds of the length of the container door 3, so that the length of the handle inside the protrusion 4 is long enough to allow a larger range of outward pulling force when the hand pulls the handle, thereby effectively pulling the heavy security door.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
