The purpose of the present invention is to improve the overall aesthetics of the examination table, simplify subsequent disassembly and maintenance, and reduce the risk of contamination or damage. A description thereof will be given below with reference to the accompanying drawings.

[0036] Figure 1 A schematic diagram showing an application scenario of an examination bed provided by an embodiment of the present invention is shown. Figure 2 The figure shows the assembly structure diagram of the examination bed provided by one embodiment of the present utility model. Figure 3 A schematic structural diagram of a bottom shell provided by an embodiment of the present invention is shown. Figure 4 The following is a schematic diagram showing the exploded structure of an examination bed provided by an embodiment of the present invention. Figure 5 A schematic structural diagram showing the connection between the bottom shell and the internal structure provided by one embodiment of the present utility model is shown.

[0037] like Figures 1 to 5 As shown, the examination bed includes: an internal structure 10, a shell assembly 100 and a bed board 200. Optionally, the examination bed further includes a headrest 300, which is detachably mounted on the front end of the bed board 200.

[0038] The rear end of the bed board 200 is inserted into the housing assembly 100 and detachably secured to the internal structure 10. The bed board 200 and the internal structure 10 are preferably secured together using screws 140. Specifically, the rear end of the bed board 200 is inserted beneath the internal structure 10, and then the internal structure 10 and the bed board 200 are tightened with an appropriate number of screws 140 to vertically lock the bed board 200.

[0039] The internal structure 10 refers to mechanical components and / or electrical components hidden in the shell assembly 100 , which can support and fix the bed board 200 and the shell assembly 100 .

[0040] In an exemplary embodiment, the internal structure 10 is disposed on the column 20 in a liftable manner, and thus the shell assembly 100 and the bed board 200 can be lifted and lowered along the column 20 together with the internal structure 10 .

[0041] In other embodiments, the internal structure 10 may not be lifted or lowered, that is, may not provide a lifting function.

[0042] Specifically, the housing assembly 100 includes an upper cover 110, a bottom shell 120, and a locking device 130. The upper cover 110 is detachably attached to the bottom shell 120, that is, the upper cover 110 can be connected to and separated from the bottom shell 120 at any time.

[0043] It should be understood that the housing assembly 100 has at least two states: a disconnected state and a connected state. The disconnected state occurs when the upper cover 110 and the bottom shell 120 are disconnected, while the connected state occurs when the upper cover 110 and the bottom shell 120 are connected. In the connected state, the upper cover 110 covers the bottom shell 120, and the upper cover 110 and the bottom shell 120 are locked together by the locking device 130.

[0044] Specifically, if Figure 3 and Figure 4 As shown, the locking device 130 includes a lock 131 and a lock tongue 132; the lock 131 is arranged on the inner surface of the bottom shell 120; the lock tongue 132 is arranged on the inner surface of the upper cover 110 (that is, the surface facing the bottom shell 120); based on this, through the cooperation between the lock 131 and the lock tongue 132, the upper cover 110 and the bottom shell 120 can be quickly assembled, and conversely, the upper cover 110 can be quickly removed.

[0045] Those skilled in the art should know that the working principle of the locking device 130 is that based on the action of the locking tongue 132 on the locking buckle 131 (such as pressing), the locking buckle 131 is able to clamp or release the locking tongue 132, thereby controlling the connection and separation of the upper cover 110 and the bottom shell 120.

[0046] Thus, the locking and unlocking method provided by the locking device 130 can effectively simplify the connection and separation operations of the upper cover 110 and the bottom shell 120, greatly simplifying the installation and removal process, improving work efficiency, and facilitating subsequent disassembly and maintenance. At the same time, it can also reduce the use of external screws to a certain extent, improving the overall aesthetics of the examination bed while reducing the risk of contamination and damage.

[0047] In practice, the locking device 130 can adopt various detachable locking structures. Although the following embodiments are described in conjunction with the ball-bump locking method in the accompanying drawings, it should be understood that various other detachable locking connection methods can also be adopted. Although the locking method of this embodiment may have a simpler structure, be more convenient to use, and lock more securely, this embodiment should not be limited to this locking connection method. Therefore, in addition to the locking methods listed in the accompanying drawings, those skilled in the art can find other alternative methods based on the description of this application to achieve the functions described in this application / achieve the above-mentioned effects, not just the solutions disclosed in this embodiment.

[0048] In this embodiment, the lock buckle 131 is preferably a ball-bump lock buckle, and the lock tongue 132 is a structure that cooperates with the ball-bump lock buckle, which has the advantages of simple structure, easy use, and secure connection. Optionally, the lock buckle 131 is provided on a mounting seat 133, and the mounting seat 133 is directly fixed to the inner surface of the bottom shell 120.

[0049] The present application does not impose any particular limitation on the number of locking devices 130. Specifically, one, two, or more locking devices 130 may be used. Preferably, there are at least two locking devices 130, and all locking devices 130 are evenly distributed around the joint between the upper cover 110 and the bottom shell 120, thereby ensuring that the seam between the bottom shell 120 and the upper cover 110 is uniform and the edges are neat and close fitting.

[0050] In a preferred embodiment, there are four locking devices 130. The locks 131 of the four locking devices 130 are arranged on the inner surface of the bottom shell 120 and are evenly distributed around the junction of the upper cover 110 and the bottom shell 120. Figure 3 Accordingly, the locking tongues 132 of the four locking devices 130 are disposed on the inner surface of the upper cover 110 and are evenly distributed around the junction of the upper cover 110 and the bottom shell 120 , and the positions of the locking tongues 132 correspond to those of the locking buckles 131 .

[0051] The present application uses four locking devices 130 to better lock the upper cover 110 and the bottom shell 120, making the locking more secure, and the joints between the upper cover 110 and the bottom shell 120 are more uniform, the appearance quality is better, the quantity is appropriate, and it is easy to use.

[0052] In the embodiment of four locking devices 130, the locks 131 of the two locking devices 130 are preferably arranged near the rear end of the bottom shell 120, and correspondingly, the locking tongues 132 of the two locking devices 130 are arranged near the rear end of the upper cover 110; in this way, the rear end of the upper cover 110 and the rear end of the bottom shell 120 are effectively joined, ensuring the connection strength of the shell assembly 100 at the rear end and preventing the rear end from warping.

[0053] In addition, if Figure 1 and Figure 5 As shown, in actual use, the bottom shell 120 needs to be detachably fixed to the internal structure 10. Specifically, the left and right sides of the bottom shell 120 are connected to the internal structure 10, so that the fixing direction between the bottom shell 120 and the internal structure 10 is the left and right direction, avoiding the up and down fixing direction of the bed board 200 and the up and down covering direction of the upper cover 110.

[0054] Preferably, the bottom shell 120 is fixed to the internal structure 10 by screws 140. In this article, all screw connection methods have the advantages of easy operation, low cost, good applicability, and detachability, especially the detachable screw connection, which makes maintenance and replacement easier.

[0055] A receiving space 121 is reserved between the bottom shell 120 and the internal structure 10, and the rear end of the bed board 200 can be inserted into the receiving space 121 and detachably fixed to the internal structure 10. The size of the receiving space 121 can be equal to or slightly larger than the thickness of the bed board 200.

[0056] Furthermore, the bottom portion 122 of the bottom shell 120 can be designed based on the outer shape of the bed board 200, so that the shape of the bottom portion 122 matches the outer shape of the bed board 200 and a receiving space 121 is reserved between the bottom portion 122 and the internal structure 10. Specifically, in this embodiment, the bottom portion 122 of the bottom shell 120 can be designed based on the curved bed surface of the bed board 200 and be proportionally enlarged so that the bottom portion 122 of the bottom shell 120 can wrap around the outer side of the curved bed surface.

[0057] Preferably, the shell assembly 100 also includes: at least two connectors 150. At least two connectors 150 are arranged on the inner surface of the bottom shell 120 and are detachably fixed to the internal structure 10. Here, the provision of the connectors 150 is conducive to the connection of the bottom shell 120 with the internal structure 10 on the inner side without affecting the appearance. The number of the connectors 150 can be two, four or more, and preferably, four connectors 150 are used. In this embodiment, the four connectors 150 are provided on the inner surface of the bottom shell 120 and are evenly distributed around the junction of the upper cover 110 and the bottom shell 120, so that the bottom shell 120 and the internal structure 10 can be effectively locked.

[0058] Preferably, the connector 150 is fastened to the internal structure 10 by screws 140 , and the number of screws 140 used in each connector 150 is not limited. In an exemplary embodiment, each connector 150 is fastened to the internal structure 10 by two screws 140 .

[0059] In an exemplary embodiment, the connector 150 is connected to the mounting base 133 and preferably secured with screws 140. This allows the connector 150 and the locking mechanism 130 to be integrated into one piece, thereby reducing the number of mounting points on the bottom case 120, simplifying the structure, and improving the overall aesthetics. Of course, in other cases, the connector 150 can be separate from the locking mechanism 130.

[0060] The connector 150 is preferably a sheet metal member, and its specific shape and size are not limited. For example, the connector 150 is an L-shaped member, one end of which is secured to the mounting seat 133 via a screw 140, and the other end is secured to the internal structure 10 via two screws 140. The number of screws 140 is not intended to be limiting.

[0061] Furthermore, considering that the bottom shell 120 and the upper cover 110 may have uneven seams or warping at some joints, in some preferred embodiments, when the upper cover 110 is placed on the bottom shell 120, the upper cover 110 and the bottom shell 120 are further locked together by screws 140. The screw locking position can be adjusted according to actual conditions and needs. For example, the screws 140 can be used to lock the upper cover 110 and the bottom shell 120 in the vertical direction, or in the front-to-back direction.

[0062] Please focus on Figure 3 In some cases, the bottom shell 120 is open in the front-to-back direction and at the top. The front-to-back opening facilitates the disassembly and assembly of the bottom shell 120 along the bed board 200, and the top opening is used to install the upper cover 110.

[0063] For this reason, Figure 4 As shown, in some embodiments, the upper cover 110 has an upper portion 111 and a front portion 112; the front portion 112 is disposed on one side (i.e., the front side) of the upper portion 111. Furthermore, when the upper cover 110 is placed on the bottom shell 120, the upper portion 111 covers the top opening of the bottom shell 120, and the front portion 112 covers the front opening of the bottom shell 120. Simultaneously, the upper portion 111 and the bottom shell 120 are locked together by a locking device 130. The upper cover 110 thus seals the top and front ends of the bottom shell 120, while allowing the rear end of the bottom shell 120 to be inserted into the internal structure 10 and positioned opposite the pillar 20.

[0064] In some embodiments, the front portion 112 and the front opening of the bottom shell 120 just abut against each other, and no additional locking is required between the two.

[0065] In other embodiments, the front portion 112 and the bottom shell 120 are fastened together by the screws 140 and / or the locking device 130, which can effectively prevent problems such as warping and uneven seams in the front portion 112. Specifically, in this embodiment, the front portion 112 and the bottom shell 120 are fastened together only by the screws 140.

[0066] The front portion 112 and the bottom shell 120 may be fastened together by a suitable number of screws 140 , including but not limited to two screws 140 .

[0067] In this embodiment, the left and right edges of the front portion 112 are secured to the left and right edges of the front opening of the bottom shell 120 by two or more screws 140, with all screws 140 being symmetrically distributed. This arrangement allows the entire housing assembly 100 to be provided with only a few external screws at the front, with no external screws at other locations. For disassembly and maintenance, simply unscrew the screws 140 at the front portion 112 and operate the locking mechanism 130 to easily open the top cover 110 for maintenance. This operation is very convenient, and the use of external screws is minimal, resulting in a well-designed overall appearance.

[0068] Furthermore, the bottom of the front portion 112 is preferably adapted to the shape of the bed board 200. For example, in this embodiment, the bed board 200 has a curved surface, and the bottom of the front portion 112 is also curved to match the curved surface of the bed board 200, improving the overall aesthetics and making installation and alignment easier. Furthermore, the outer surface of the upper portion 111 may be provided with a finger operation hole 113 for finger operation.

[0069] The following further describes the assembly method between the shell assembly 100 and the bed board 200 provided in the embodiment of the present application.

[0070] In the first assembly method, the rear end of the bed board 200 is fixed to the internal structure 10 in advance, and then the bottom shell 120 is inserted into the front end of the bed board 200 and slid along the length direction of the bed board 200 to the rear end of the bed board 200. After that, the bottom shell 120 is locked to the internal structure 10, and finally the upper cover 110 is installed and locked.

[0071] In the second assembly method, the bottom shell 120 is first locked on the internal structure 10, then the rear end of the bed board 200 is inserted into the accommodating space 121 between the internal structure 10 and the bottom shell 120, and then the bed board 200 and the internal structure 10 are locked, and finally the upper cover 110 is installed and locked.

[0072] When disassembly is required, in a preferred scenario, it is only necessary to unscrew the two screws 140 of the front end portion 112 of the upper cover 110 and then pull the upper cover 110 upward to remove the upper cover 110 for maintenance or replacement.

[0073] In summary, the present invention provides a shell assembly 100, which can be installed on the rear end of the bed board 200 of the scanning device when in use, and then the rear end of the bed board 200 and the bottom shell 120 of the shell assembly 100 and the internal structure 10 are detachably fixed. The shell assembly 100 and the bed board 200 can be supported and fixed with the help of the internal structure 10 to ensure the overall stability and durability of the bed board 200.

[0074] On this basis, the housing assembly 100 itself locks the upper cover 110 and the bottom shell 120 through the locking device 130, achieving convenient assembly, effectively simplifying the connection and separation operations of the upper cover 110 and the bottom shell 120, improving work efficiency, and to a certain extent reducing the use of external screws, improving the overall aesthetics of the examination bed, while also reducing the risk of contamination and damage, improving hygiene and durability, and facilitating subsequent disassembly and maintenance. Moreover, the assembly method provided in this application can be adjusted and applied according to the design of different bed bodies, and can adapt to the needs of bed bodies of different models and specifications, with high flexibility.

[0075] Not only that, the bottom shell 120 and the upper cover 110 in the shell assembly 100 can also be locked by screws 140, which not only enhances the locking effect but also further improves the overall aesthetics. In particular, the bottom shell 120 and the upper cover 110 only need to be locked at the front position by external screws, which greatly reduces the number of external screws, simplifies the operation, reduces the risk of screw damage and contamination, and improves production efficiency.

[0076] While the present invention is disclosed above, it is not limited thereto. Persons skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the present invention and its equivalents, the present invention is intended to encompass such modifications and variations.
