Description

Technical Field

[0001] This application relates to the field of barcode scanner bracket technology, and more specifically, to a barcode scanner bracket and a trolley having the barcode scanner bracket. Background Technology

[0002] Barcode scanners, especially handheld ones, are widely used in the healthcare field. For example, when examining or treating patients using medical supplies on a trolley, it is often necessary to immediately input patient identification information or medical supply information. In this case, healthcare professionals generally rely on handheld barcode scanners to scan the barcodes / QR codes on the patient's wristband or the medical supplies to complete this operation, significantly improving the efficiency and accuracy of information entry.

[0003] When handheld barcode scanners are needed, medical staff often simply place them haphazardly on the table of the trolley. This haphazard placement presents the following problems:

[0004] 1) Cluttered work surface: Handheld barcode scanners and their cables are placed haphazardly on the work surface, which undermines the cleanliness and professionalism of the work surface;

[0005] 2) Hinders operation: The handheld barcode scanner and its cable placed on the table will occupy the already limited table space and may interfere with other medical items or the movements of medical staff, thus hindering the operation of medical staff.

[0006] 3) Increased risk of damage: Handheld barcode scanners that are placed carelessly are easily knocked down or come into contact with other medical items, increasing the risk of damage to the handheld barcode scanners and other medical items;

[0007] Therefore, there is an urgent need for a solution that can effectively address the above problems and provide a convenient, stable, and space-saving placement solution for handheld barcode scanners on a trolley. Summary of the Invention

[0008] This application aims to solve the technical problems caused by handheld barcode scanners being placed haphazardly on the table of a trolley, resulting in table clutter, obstructed operation, and easy damage to items. To address this technical problem, a first aspect of this application provides a barcode scanner holder, which may include a mounting base and a support tray. The mounting base is configured to be mounted on a rod-like object. The support tray may be disposed on the mounting base. The support tray may include a disc body and a protrusion extending upward along the edge of the disc body. The protrusion may protrude from the upper surface of the disc body. The protrusion may be configured to limit a portion of a handheld barcode scanner supported on the disc body. The protrusion may have an upward-opening locking opening. The locking opening is used to hold another portion of the handheld barcode scanner. The bottom of the locking opening may be higher than the upper surface of the disc body.

[0009] The mounting base for the barcode scanner holder can be installed on a rod-like object, such as a handle on a trolley, thus providing a fixed placement position for the handheld barcode scanner. Different parts of the handheld barcode scanner are positioned by engaging the locking opening and protrusions, and the locking opening raises a portion of the handheld scanner, allowing it to be reliably placed on the support tray. This solves a series of problems caused by haphazard placement of handheld barcode scanners, such as cluttered work surfaces, obstructed operation, and potential damage to items, while ensuring the safety of the handheld scanner placed on the holder. Furthermore, by appropriately selecting the dimensions of the locking opening and the tray, the holder can accommodate various models of handheld barcode scanners and allows users to place the scanner in multiple ways, offering high convenience. The holder also boasts advantages such as compact size and simple structure.

[0010] Another aspect of this application provides a trolley. The trolley may include a rod-like object, which may be a handle disposed on the top side of the trolley. The trolley may also include a barcode scanner bracket of any of the above embodiments, with the mounting base of the barcode scanner bracket mounted on the handle. Because the trolley includes a barcode scanner bracket of any of the above embodiments, the trolley can have the beneficial effects of any of the above-described barcode scanner brackets.

[0028] In the following description, numerous details are provided to enable a thorough understanding of this application. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the application, and that the application can be implemented without one or more of these details. Furthermore, to avoid confusion with this application, some technical features well-known in the art have not been described in detail.

[0029] To fully understand the embodiments of this application, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, other embodiments may also be available in addition to these detailed descriptions.

[0030] According to one aspect of this application, a barcode scanner holder 1 is provided. (See also...) Figures 1 to 5 The barcode scanner bracket 1 may include a mounting base 100 and a support tray 200 disposed on the mounting base 100. The mounting base 100 is configured to be mounted to the rod 2 (see...). Figures 6 to 7 In some embodiments, the mounting base can take any suitable structure, as long as it can be secured to the rod and keep the support tray disposed thereon stable. Exemplarily, the mounting base can be constructed as a clamp. The clamp can be made of an annular sheet with an opening. After the clamp is fitted onto the rod, the opening of the annular sheet can be locked using any suitable fastener, thereby securing the clamp to the rod. The support tray can be mounted on any suitable portion of the annular sheet. Exemplarily, the mounting base can be constructed as a clip that can be clamped onto the rod.

[0031] The tray 200 may include a tray body 210 and a protrusion 220 extending along the edge of the tray body 210. The protrusion 220 may project upwards beyond the upper surface of the tray body 210. The tray 200 may be made of any material such as plastic or metal. Figure 1 , Figure 3 As shown, the disc body 210 can be disc-shaped. The disc-shaped disc body 210 has no sharp edges, making it less likely to cause injury upon impact. In other embodiments not shown, the disc body can also be any suitable polygonal disc shape. The upper surface of the disc body 210 can be flat as shown, or it can be recessed. Optionally, the upper surface of the disc body 210 can be provided with a suitable pattern or have other soft pads attached to it for anti-slip purposes.

[0032] like Figure 1As shown, the protrusion 220 can extend continuously along the entire edge of the disk body 210 to form an annular structure that generally surrounds the disk body 210. In embodiments not shown, the protrusion 220 can extend along a portion of the edge of the disk body 210 to surround one-quarter, more, or less (e.g., half of the circumference of the disk body 210). In embodiments not shown, the protrusion can also extend discontinuously along the edge of the disk body, in which case there can be multiple protrusions, spaced apart along the edge of the disk body. Optionally, the multiple protrusions can be evenly distributed around the disk body, or, of course, can be located at local edges of the disk body as needed. Furthermore, although in the illustrated embodiment, a portion of the protrusion 220 is significantly higher than other portions, i.e., this portion of the protrusion 220 protrudes more from the upper surface of the disk body 210 than other portions, in other embodiments not shown, the various portions of the protrusion 220 can have approximately the same height.

[0033] Because the protrusion 220 protrudes upward from the upper surface of the disc body 210, at least a portion of the handheld barcode scanner supported on the disc body 210 can be limited. Furthermore, as... Figure 1 and Figure 4 As shown, the protrusion 220 may have an upward-facing locking opening 221. The locking opening 221 can be used to hold another part of the handheld barcode scanner. Exemplarily, the other part of the handheld barcode scanner may be partially or completely locked into the locking opening 221. Exemplarily, the locking opening 221 may extend from the inner peripheral side to the outer peripheral side of the protrusion 220. This allows a portion of the handheld barcode scanner to extend beyond the support tray 200, thereby reducing the size of the support tray 200. Of course, for small handheld barcode scanners, they can also be entirely supported on the disc body 210, in which case the body of the small handheld barcode scanner can be completely limited by the protrusion 220.

[0034] Typically, a handheld barcode scanner may include a body and a cable. The body includes a wide head and a handle connected to the head. The head may house the optical system of the handheld barcode scanner, such as a light source and a light signal receiving element. The circuitry of the handheld barcode scanner may be housed within the handle. The cable of the circuitry may extend from the tail of the handle, and the cable may provide power and transmit signals to the handheld barcode scanner. Exemplarily, the top width (i.e., horizontal dimension) of the locking opening 221 may be greater than the width of the connection portion between the head and the handle (referred to as the neck), but less than the width of the head. This allows the neck of the handheld barcode scanner to engage with the locking opening 221.

[0035] In the first usage of the barcode scanner holder 1, the tail of the handheld barcode scanner can be supported on the disc body 210, and the neck can be held in place by the locking opening 221. Then, the handheld barcode scanner can be slightly pulled toward the inner periphery of the disc body 210, so that the head of the handheld barcode scanner abuts against the protrusion 220 at the locking opening 221 on the outer periphery of the protrusion 220, thereby reliably placing the handheld barcode scanner on the barcode scanner holder 1.

[0036] In the second usage of the barcode scanner holder 1, the head of the handheld barcode scanner can be supported on the disc body 210, and then the handheld part (e.g., the middle or the tail of the handheld part) can be locked into the locking opening 221.

[0037] For different models, the various parts of a handheld barcode scanner may have different dimensions. Therefore, to accommodate handheld barcode scanners of different sizes, the width of the locking opening 221 can, for example, gradually decrease in the downward direction. In this way, for most handheld barcode scanners on the market, regardless of the usage method, the part that is locked into the locking opening 221 can contact the side walls of the locking opening 221 on both sides, preventing the handheld barcode scanner from shaking in the horizontal direction.

[0038] As mentioned above, typically, a portion of the handheld barcode scanner extends beyond the tray 200. To further ensure safety, such as... Figure 1 and Figure 4 As shown, the bottom of the locking opening 221 can be higher than the upper surface of the tray 210. This allows the portion of the handheld barcode scanner extending beyond the support tray 200 to be raised, thereby keeping the center of gravity of the handheld barcode scanner within the support tray 200. This prevents the handheld barcode scanner from falling off the barcode scanner holder 1 due to improper user operation causing excessive extension of the handheld barcode scanner beyond the tray 200, or accidental impact to the portion extending beyond the tray 200, etc.

[0039] The mounting base 100 of the barcode scanner bracket 1 provided in the embodiments of this application can be mounted on the rod-shaped object 2, such as... Figure 6 , Figure 7As shown, for example, the barcode scanner holder 1 can be mounted on the rod-like part 2 (e.g., handle) of the trolley 3, thereby providing a fixed placement position for the handheld barcode scanner. The tray 200 of the barcode scanner holder 1 includes a locking opening 221 and a protrusion 220. The locking opening 221 and the protrusion 220 cooperate to limit different parts of the handheld barcode scanner, and by using the locking opening 221 to raise a part of the handheld barcode scanner, the handheld barcode scanner can be reliably placed on the tray 200. This solves a series of problems caused by the random placement of handheld barcode scanners, such as table clutter, obstruction of operation, and easy damage to items, and ensures the safety of the handheld barcode scanner placed on the barcode scanner holder 1. In addition, by reasonably selecting the size of the locking opening 221 and the tray 200, it is possible to adapt the barcode scanner holder 1 to various models of handheld barcode scanners, and it allows users to place the handheld barcode scanner on the barcode scanner holder 1 in multiple ways, making it highly convenient to use. Furthermore, the barcode scanner bracket 1 also has the advantages of being compact and simple in structure.

[0040] For example, the protrusion 220 can be configured to surround the base of a desktop barcode scanner placed on the disk body 210. That is, in the barcode scanner holder 1 provided in the embodiments of this application, as long as the size of the disk body 210 is reasonably selected, the base of the desktop barcode scanner can be placed on the disk body 210, and the protrusion 220 limits the position of the desktop barcode scanner base in the horizontal direction. In this way, there is no need to design a separate structure for the support tray 200; as long as its size is reasonably selected, the barcode scanner holder 1 can accommodate two types of barcode scanners, thereby increasing the applicability of the barcode scanner holder 1.

[0041] In some embodiments, to better limit the bottom of the desktop barcode scanner, the shape of the disc body 210 can be reasonably selected according to the shape of the bottom of the target desktop barcode scanner, so that the protrusion 220 on the edge of the disc body 210 can be adapted to the base of the desktop barcode scanner. Of course, if it is desired to adapt to more models of desktop barcode scanners, the size of the disc body 210 can be made larger.

[0042] like Figure 1 , Figure 2 and Figure 4As shown, the mounting base 100 may include a first arm 110 and a second arm 120. The first arm 110 and the second arm 120 may be made of any suitable material such as plastic, wood, or alloy. A support tray 200 may be disposed on the first arm 110. Exemplarily, the support tray 200 may be detachably or non-detachably connected to the first arm 110 via a connecting structure 230. In embodiments not shown, the support tray and the first arm may be a single piece. The second arm 120 may be folded and opened relative to the first arm 110. In some embodiments, the first arm 110 and the second arm 120 may be configured to be completely separable. In embodiments not shown, the first arm and the second arm may be connected together by a hinge or similar means, without being completely separated.

[0043] When the first arm 110 and the second arm 120 are closed, they can cooperate to form a through hole 130 for the rod-like object to pass through. Exemplarily, the shape and size of the through hole 130 can perfectly match the shape and size of the rod-like object, so that the first arm 110 and the second arm 120 can fit together when closed. Optionally, the first arm 110 and the second arm 120 may not fit together completely when closed, but the rod-like object can still be held between them. In some embodiments, the through hole 130 can be formed by the grooves of the first arm 110 and the second arm 120. When the first arm 110 and the second arm 120 are closed, they can be fixed together by a fastener 140. The fastener 140 can be any of a threaded fastener, a spring pin, etc. Optionally, if the first arm 110 and the second arm 120 are threaded holes, the threaded fastener can be a bolt. Optionally, if the first arm 110 and the second arm 120 are not threaded holes, the threaded fastener can include a bolt and a nut. Optionally, if the first arm 110 and the second arm 120 are not threaded holes, the fastener 140 can include a spring pin. When the first arm 110 and the second arm 120 are separated, the rod-like object can disengage from the through hole 130.

[0044] Therefore, the mounting base 100 can be easily fixed to the rod by the cooperation of the first arm 110 and the second arm 120. Moreover, this mounting base 100 can take into account the advantages of simple structure, easy installation and use, convenient production and processing, and reliable fixation on the rod.

[0045] like Figure 1 and Figure 4As shown, the through hole 130 may include a circular channel 131, an upper notch 132 disposed at the top of the circular channel 131, and a lower notch 133 disposed at the bottom of the circular channel 131. The openings of the upper notch 132 and the lower notch 133 are opposite to each other. The upper notch 132 and the lower notch 133 extend through the circular channel 131 along its axis. Thus, the circular channel 131 can connect with a circular rod-shaped object 2 (such as...). Figure 7 (As shown) Adaptable. The upper notch 132 and lower notch 133 can be used with a strip-shaped rod 2 (such as...) Figure 3 (As shown) Adaptation. When the barcode scanner bracket 1 is mounted on the rod 2, a gap may exist between the first arm 110 and the second arm 120. The size of the gap between the first arm 110 and the second arm 120 will vary depending on the thickness or diameter of the rod. Therefore, the barcode scanner bracket 1 can be adapted to rods of different thicknesses or diameters.

[0046] In some embodiments, a gasket may be provided between the through-hole and the rod-like object. The gasket may be any one of silicone strips, rubber sheets, etc. This prevents the through-hole material from damaging the rod-like object. When the diameter of the through-hole is larger than the diameter of the rod-like object or the thickness of the notch is larger than the thickness of the rod-like object, a gasket can be used to fill the gap between the through-hole and the rod-like object, ensuring a firm fit between them.

[0047] For example, such as Figure 4 , Figure 6 , Figure 7 As shown, the first arm 110 and the second arm 120 can be arranged side by side in a horizontal direction. The second arm 120 may have abutment portion 121, which protrudes toward the side away from the first arm 110. In embodiments where the rod 2 is mounted on the trolley 3, for example as the handle of the trolley 3, the rod 2 is typically located on the side of the trolley 3 and spaced horizontally from the side of the trolley 3. In this case, the second arm 120 can be mounted between the side of the trolley 3 and the rod 2, while the first arm 110 is mounted on the outside of the rod 2. The abutment portion 121 of the second arm 120 can protrude toward the side of the trolley 3. The abutment portion 121 can abut against the side of the trolley 3 when the barcode scanner bracket 1 is tilted. When the barcode scanner bracket 1 is stably mounted on the rod 2, i.e., the support tray 200 remains horizontal, there can be a gap between the abutment part 121 and the side of the trolley 3. This allows the second arm 120 to be easily installed between the rod 2 and the side of the trolley 3 during the installation of the barcode scanner bracket 1. Even if the connection between the barcode scanner bracket 1 and the rod 2 becomes loose, and the support tray 200 tilts slightly, the abutment part 121 can still abut against the side of the trolley 3, maintaining the stability of the support tray 200, preventing it from tipping over, and thus preventing the barcode scanner from falling and being damaged.

[0048] In other embodiments not shown, the rod 2 may be another component of the trolley 3 itself or an additional component provided on the trolley 3 for mounting the barcode scanner bracket 1. In this case, any suitable side surface of the rod 2 can be selected as the first surface for the abutment 121 to abut against when the tray 200 is slightly tilted. This first surface may be horizontally spaced from the rod 2 for the second support arm 120 to be inserted therein. In embodiments where the rod 2 is a handle of the trolley 3, the first surface may include the side of the trolley 3.

[0049] In embodiments not shown, the first and second arms may also be arranged vertically. An abutment may be provided on the first and / or second arms for abutting against the first surface when the barcode scanner holder tilts due to rotation along the axial direction of the rod. Exemplarily, the vertically arranged first and second arms may span the rod along their respective length directions. Each of the first and second arms may have end faces opposite each other along its respective length direction. The abutment may be provided on the end faces of the first and / or second arms to prevent the barcode scanner holder from tilting. Optionally, the first and / or second arms may also be extended along their length to form the abutment. Thus, the first and second arms are respectively mounted on the top and bottom surfaces of the rod. This eliminates the need to insert the first or second arm into the narrow space between the first surface and the rod, although it may be necessary to secure fasteners from the bottom through the second arm to the first arm to mount the mounting to the rod. The pallet can be fixed to the first arm at the top.

[0050] Additionally, it should be noted that although the first arm 110 and the second arm 120 have different structures in the illustrated embodiment, for example, the first arm 110 is generally columnar and the second arm 120 is generally L-shaped, in other embodiments not shown, the first arm 110 and the second arm 120 may have the same or similar structures, for example, both may be columnar or L-shaped.

[0051] like Figure 2 , Figure 4As shown, a fastening through hole 111 can be provided on the first arm 110. When the first arm 110 and the second arm 120 are closed, the fastener 140 can pass through the fastening through hole 111 and connect to the second arm 120. Continuing with the embodiment where the barcode scanner bracket 1 is mounted on the rod-shaped object 2 of the trolley 3, the first arm 110 is located on the outside of the rod-shaped object 2. Therefore, by providing the fastening through hole 111 on the first arm 110, the fastener 140 can be operated from the outside to pass through the fastening through hole 111 and connect to the second arm 120. This provides a larger operating space and facilitates installation. For example, the placement of the tray 200 on the outer side of the first arm 110 also has the following advantages: when the barcode scanner bracket 1 is mounted on the rod 2, the tray 200 and the first arm 110 can be kept connected together (or the two can be non-detachably connected together or directly made into one piece), and the relatively small second arm 120 can be inserted into the gap between the rod 2 and the side of the trolley 3, making installation more convenient.

[0052] Taking the barcode scanner bracket 1 applied to the trolley 3 as an example, such as Figure 6 and Figure 7 As shown, the user may wish to mount the barcode scanner bracket 1 to the left handle (i.e., the left rod 2) of the trolley 3, or may wish to mount the barcode scanner bracket 1 to the right handle (i.e., the right rod 2) of the trolley 3. To meet the above mounting requirements, the inventors have proposed a new design for the connection structure 230 that connects the tray 200 to the first arm 110. This design is applicable to any of the above embodiments, and is particularly applicable to embodiments in which the first arm 110 and the second arm 120 are arranged in a horizontal direction and the first arm 110 and the second arm 120 have different structures.

[0053] To distinguish between different horizontal directions, the horizontal direction in which the first arm 110 and the second arm 120 are arranged side by side is referred to as the first horizontal direction. The support tray 200 is detachably connected to the first arm 110 via a connecting structure 230. The connecting structure 230 may include one or more threaded fasteners or one or more spring pins, etc. Typically, the support tray 200 and the first arm 110 need to be provided with matching connecting structures to the connecting structure 230, such as fastening holes. Furthermore, in designing this barcode scanner bracket 1, the disc body 210 can be symmetrical with respect to the first arm 110 in at least one horizontal direction, for example, symmetrical in the first horizontal direction (i.e., the support tray 200 is symmetrical about a centerline passing through the center of the first arm 110 and perpendicular to the first horizontal direction, such as...). Figure 8A The middle plate 210 is symmetrical about the first support arm 110 (either horizontally or horizontally), or symmetrical in a second horizontal direction perpendicular to the first horizontal direction (i.e., the tray 200 is symmetrical about a centerline passing through the center of the first support arm 110 and perpendicular to the second horizontal direction). Figure 8AThe middle plate 210 is symmetrical about the first support arm 110 (either vertically or horizontally), or symmetrical about both the first and second horizontal directions, so that the first support arm 110 can provide uniform support to the support tray 200 and is more aesthetically pleasing. Furthermore, when mounted to any handle of the trolley 3, it is desirable that the second support arm 120 be inserted into the gap between the side of the trolley 3 (i.e., the first surface) and the handle, while the first support arm 110 is on the outside of the handle, so that the fastener 140 can be operated from the outside to connect the first support arm 110 to the second support arm 120, thereby securing the barcode scanner bracket 1 to the handle. For ease of description, in Figures 8A-9C The first arm 110, the second arm 120, and the fastener 140, which are covered by the pallet 200, are shown in dashed lines using a perspective method.

[0054] Based on the above situation, such as Figure 8A As shown, the connection structure 230 can be symmetrical about only the first center line AA of the support tray 200. The first center line AA passes through the center of the support tray 200 and is parallel to the first horizontal direction. Therefore, whether the barcode scanner bracket 1 is installed on the right handle or the left handle, the distance from the barcode scanner bracket 1 to the first surface 4 of the trolley 3 can be equal. Figure 8A The diagram shows the barcode scanner bracket 1 mounted on the right-side handle. However, for clarity, the handle is not shown; instead, the position of the first surface 4 is used as a reference. Figure 8B The barcode scanner bracket 1 is shown in a similar manner when mounted to the left handle. Whether the barcode scanner bracket 1 is mounted to the right or left handle, the second arm 120 is positioned close to the first surface 4 to allow for operation of the fastener 140 from the outside. Therefore, Figure 8B Compared to Figure 8A The first arm 110 and the second arm 120 are rotated 180 degrees in the plane of the paper. To make the distance from the support tray 200 to the first surface 4 equal in both mounting states, the support tray 200 is also rotated 180 degrees in the plane of the paper. However, this causes the locking opening 221 to also be rotated relative to the first surface 4. Figure 8A It is rotated 180 degrees. For example, if in Figure 8A In the installed state, the locking opening 221 is located on the rear side of the support tray 200, then... Figure 8B In the installed state, the locking opening 221 is located on the front side of the support tray 200. Alternatively, it can be used... Figure 8C In the installation configuration shown, the locking opening 221 remains on the rear side of the support tray 200, but this changes the distance between the support tray 200 and the first surface 4. Figure 8A In the installation configuration shown, the support tray 200 is approximately symmetrical with respect to the first support arm 110, but the connecting structure 230 is not approximately symmetrical with respect to the first support arm 110. Figure 8CBecause the middle support pallet 200 was not rotated 180 degrees in the paper plane along with the first arm 110 and the second arm 120, the distance from the support pallet 200 to the first surface 4 will be greater than [the distance between the support pallet 200 and the first surface 4]. Figure 8A and 8B The distance in the middle.

[0055] For example, such as Figure 9A As shown, the connecting structure 230 can be symmetrical about only the second center line BB of the support tray 200. The second center line BB passes through the center of the support tray 200 and is parallel to the second horizontal direction. Therefore, the connecting structure 230 has a first distance d1 to the edge of the support tray 200 where the locking opening 221 is located, and the connecting structure 230 has a second distance d2 to the edge of the support tray 200 where the wire harness opening 223 is located. The first distance d1 is not equal to the second distance d2. Figure 9A and Figure 9B respectively with Figure 8A and Figure 8B A similar arrangement is shown with the barcode scanner bracket 1 mounted on the right and left handles. Figure 9B Compared to Figure 9A The first arm 110 and the second arm 120 are rotated 180 degrees within the plane of the paper. Figure 9A In the shown installation configuration, the disc body 210 is vertically symmetrical with respect to the first arm 110. To achieve this symmetry between the disc body 210 and the first arm 110 in both installation configurations, the tray 200 is also rotated 180 degrees within the plane of the paper. However, this causes the locking opening 221 to also be vertically symmetrical with respect to the first arm 110. Figure 9A It was rotated 180 degrees. And if... Figure 9C If the installation state shown still maintains the locking opening 221 on the rear side of the tray 200, then the tray body 210 will not be able to achieve the above-mentioned symmetry with respect to the first support arm 110.

[0056] In another set of preferred embodiments, such as Figure 3 As shown, the connecting structure 230 can be symmetrical about both the first centerline AA and the second centerline BB of the carrier 200. Therefore, regardless of which side of the trolley 3 the barcode scanner bracket 1 is installed on, only the positions of the first arm 110 and the second arm 120 change relative to the barcode scanner bracket 1 as a whole. The position of the carrier 200 relative to the barcode scanner bracket 1 can remain unchanged.

[0057] For example, such as Figure 3As shown, the locking opening 221 is symmetrical about the second center line BB of the support tray 200. The second center line BB is generally parallel to the extension direction of the rod. Of course, the rod can also be curved, in which case the second center line BB is generally parallel to the section of the rod where the barcode scanner holder 1 is located. Thus, in the two aforementioned usage methods of the barcode scanner holder 1, the handheld barcode scanner can be placed generally along the extension direction of the rod. As mentioned earlier, the side of the rod may have a first surface; placing the handheld barcode scanner generally along the rod avoids interference from the first surface, thus improving ease of use.

[0058] like Figure 1 , Figure 2 , Figure 6 and Figure 7 The protrusion 220 may include a rear portion located at the rear edge of the tray 200. The rear portion is higher than the other parts of the protrusion 220, and a locking opening 221 is provided on the rear portion. The rear side can be the side furthest from the person after the barcode scanner bracket 1 is mounted to the rod 2. By providing the locking opening 221 on the rear portion, the head of the handheld barcode scanner, locked in the locking opening 221, will be aligned with the side furthest from the person. This avoids the barcode scanner head scanning the person's eyes and causing harm. Furthermore, in the event of an accident, the person will not bump into the more distant rear portion.

[0059] like Figures 1 to 7 In the illustrated embodiment, the portions of the protrusion 220, excluding the rear portion, can have substantially the same height, such that the rear portion includes two distinctly protruding parts, and the locking opening 221 can be formed between these two protruding parts. Optionally, as... Figure 10 As shown, in another embodiment, the protrusion 220' may have a gradually decreasing height from the rear portion to the front portion, thereby preventing a noticeable protrusion from forming on the rear side of the tray 200'. However, to ensure sufficient depth of the locking opening 221, the average height of the protrusion 220' in this embodiment may be greater than [missing information]. Figures 1 to 7 The average height of the protrusion 220 in the illustrated embodiment. Those skilled in the art can reasonably select the structure of the protrusion as needed. It should be noted that... Figure 10 In the embodiments shown, and Figures 1 to 7 In the embodiments shown, similar or identical components are referred to by the same reference numerals, and for the sake of brevity, they will not be described in detail here.

[0060] See back Figure 1A cable management hole 222 may be provided on the protrusion 220. The cable management hole 222 extends from the inner circumference of the protrusion 220 to the outer circumference. The cable management hole 222 may be located below the retaining opening 221. Preferably, when storing the desktop barcode scanner, the cable management hole 222 can be used to allow the cable of the desktop barcode scanner to pass through. The cable of the desktop barcode scanner is usually located on the rear side of the desktop barcode scanner. The cable management hole 222 is located below the retaining opening 221, and can be located on the rear side like the retaining opening 221. In this way, the front side of the desktop barcode scanner is on the side closer to the user, which is convenient for scanning various barcodes. The cable passes through the cable management hole 222 on the rear side, which is convenient for storing and organizing the cable. At the same time, due to the limiting effect of the cable management hole 222, it can also prevent the desktop barcode scanner from falling to the ground due to accidental damage.

[0061] like Figure 1 As shown, the protrusion 220 may be provided with an upward-facing cable routing opening 223. The cable routing opening 223 extends from the inner peripheral side of the protrusion 220 to the outer peripheral side. Exemplarily, the cable routing opening 223 and the locking opening 221 are arranged opposite each other about the center of the disc body 210. When the neck of the handheld barcode scanner is held in place by the locking opening 221, the cable routing opening 223 can be used for the cable of the handheld barcode scanner to pass through, further fixing the position of the handheld barcode scanner and preventing cable tangling.

[0062] Specifically, the barcode scanner bracket is used for mounting on a trolley carrying a near-infrared brain functional imaging device. Generally, near-infrared brain functional imaging devices come in various types, such as desktop and portable. Different types of near-infrared brain functional imaging devices may have different types of barcode scanner interfaces for mounting different types of barcode scanners, such as handheld and desktop barcode scanners. Ideally, after various types of near-infrared brain functional imaging devices are mounted on the trolley, a suitable barcode scanner bracket should be provided for placing their corresponding barcode scanners. Preferably, it is desirable to provide a more widely applicable barcode scanner bracket that can accommodate different types of barcode scanners. This way, near-infrared brain functional imaging device manufacturers do not need to design separate matching brackets for each type of barcode scanner, and when the barcode scanner type is changed, there is no need to redesign a new barcode scanner bracket, resulting in lower manufacturing costs and greater convenience. Specifically, the cable routing hole 222 can be located below the mounting opening 221, and the cable routing hole 222 and the mounting opening 221 can both be located on the rear side of the protrusion 220. This allows both handheld and desktop barcode scanners to be placed on the barcode scanner holder, making it convenient for scanning barcodes and expanding its application range. It can effectively improve the application efficiency of the barcode scanner holder and prevent the more protruding rear part of the protrusion 220 from bumping into people.

[0063] In embodiments where the locking opening 221 is located on the rear side of the protrusion 220, the cable routing opening 223 and the locking opening 221 can be arranged opposite each other about the center of the disc body. Thus, by restraining the head of the handheld barcode scanner through the locking opening 221 and by restraining the cable of the handheld barcode scanner through the cable routing opening 223, the position of the handheld barcode scanner is stably restrained. This ensures that the barcode scanner head is stably facing away from the human body, preventing the tail position from changing and causing the barcode scanner head to shift, accidentally scanning the human eye and causing harm.

[0064] In embodiments where the cable routing hole 222 is located below the retaining opening 221, the cable routing opening 223 and the retaining opening 221 can be arranged opposite each other about the center of the tray. Thus, the retaining opening 221, the cable routing opening 223, and the cable routing hole 222 can be on the same horizontal direction passing through the center of the tray, allowing the tray 200 to have a symmetrical structure overall, facilitating manufacturing. Furthermore, this design is suitable for use with either handheld or fixed barcode scanners, and can be adapted to most medical devices currently equipped with barcode scanners, effectively improving the application efficiency of the barcode scanner holder.

[0065] like Figure 6 and Figure 7 As shown, according to another aspect of this application, a trolley 3 is also provided. Exemplarily, the trolley can be any of a medical equipment trolley, a logistics picking cart, or a mobile checkout cart, and in particular, it can be a trolley for a near-infrared brain functional imaging device. The trolley 3 may include a rod-like object 2, which may be a handle disposed on the top side of the trolley 3. The trolley 3 may also include a barcode scanner bracket 1 of any of the above embodiments, with a mounting base 100 of the barcode scanner bracket 1 mounted on the handle. Because the trolley 3 includes the barcode scanner bracket 1 of any of the embodiments of this application, the trolley 3 can have the beneficial effects of any of the above-described barcode scanner bracket 1.
