Description

Technical Field

[0001] The utility model relates to the field of furniture, in particular to a keyboard tray, in particular to an operating room keyboard tray. Background Art

[0002] Computer peripherals such as keyboards and mice are usually placed on computer desks for use. The keyboard tray can also be separated from the computer desktop as a separate component to expand the scope of application. Common ones include sliding rail keyboard trays and rotating keyboard trays. The general keyboard tray is just a keyboard tray that cooperates with the keyboard and mouse for operation. With the popularization of computers and the development of computer peripherals, some people have proposed an integrated rotating keyboard tray that integrates computer peripherals such as keyboards and USB hubs. It is a left-middle-right structure, that is, the left and right sides are the left mounting seat and the right mounting seat respectively, and the middle is the keyboard tray. This keyboard tray realizes internal wiring, and the wire only needs to be bent about 90 degrees at the joint between the mounting seat and the keyboard tray.

[0003] In the application of operating room, the keyboard tray with left-middle-right structure occupies a large space. Therefore, some people have proposed a rotating keyboard tray, which changes the left and right mounting seats to the middle mounting seat and connects the left and right mounting seats with the keyboard tray through a rotating block. Figure 1 As shown, a rotating keyboard tray is divided into a mounting sheet metal A1, a mounting support A2, a rotating shaft A3, a rotating block A4, a wire A5, and a keyboard bracket A6. Among them, the mounting support A2 is fixed on the mounting sheet metal A1, and the mounting support A2 and the keyboard bracket A6 are respectively connected through the rotating block A4; a wiring through hole is set at the bottom of the keyboard bracket A6 and in the middle of the mounting sheet metal A1, and the keyboard wire A5 is routed through the through hole at the bottom of the keyboard bracket A6 to the through hole in the middle of the mounting sheet metal A1, and the wire A5 is reserved in length so that the keyboard tray can rotate within the travel range.

[0004] The above solution realizes the change of the mounting bracket to the middle mounting, and connects the mounting bracket and the keyboard bracket through the rotating block. However, the above solution has the following problems: (1) The wire is exposed, and the outer rubber of the wire is easily oxidized by air. After the rubber is oxidized and hardened, the keyboard bracket is prone to problems when the wire is bent multiple times; (2) The wire is exposed, which is easy to accumulate dust and difficult to clean, and does not meet the application requirements of the clean environment of the operating room. Summary of the invention

[0005] The utility model aims to overcome the deficiencies of the prior art and provide a rotating keyboard tray.

[0006] The utility model solves the technical problem by adopting the following technical scheme.

[0007] A rotating keyboard tray is composed of a mounting back plate, a mounting seat, a rotating shaft, an adapter block, a keyboard wire, a keyboard tray, screws, a keyboard, and a threaded cover. The mounting seat is fixed on the mounting back plate, the keyboard tray is fixed on the adapter block by screws, the adapter block is connected to the mounting seat by a rotating shaft, and the threaded cover is fixed on the adapter block.

[0008] The top surface of the adapter block is provided with threaded holes and top through holes, the left and right sides are provided with side through holes, and the front is provided with an internal main through hole; the internal main through hole is drilled from the front of the adapter block, connecting the top through hole and the side through hole; a thread is provided at the outlet of the internal main through hole, which is connected to the threaded cover.

[0009] A rotating keyboard tray has the following internal wiring path: the keyboard wire passes through the bottom through hole of the keyboard tray, enters the top through hole of the adapter block, passes through the main through hole inside the adapter block, comes out from the side through hole of the adapter block, enters the internal through hole of the rotating shaft, then passes through the side through hole of the mounting seat and enters the back through hole of the mounting seat, and finally passes through the through hole of the mounting back plate to connect with the device.

[0010] The periphery of the keyboard is embedded and installed in a square groove set on the top of the keyboard tray, and the top of the keyboard is provided with a flange to cover the gap between the keyboard and the square groove of the keyboard tray, and sealing is achieved by applying glue at the gap.

[0011] The keyboard tray drives the adapter block to rotate upward relative to the mounting seat through the rotating shaft, and the back side of the keyboard tray contacts the top of the mounting seat, and the rotation stroke is limited.

[0012] The advantages and positive effects of the utility model are as follows.

[0013] The mounting base can be installed in the middle, and the left and right spaces on the back of the keyboard tray are released, which is of great significance for the operating room where every inch of land is valuable. The keyboard tray is fixed to the adapter block by screws. Since the depth of the groove required for the keyboard tray to be embedded in the keyboard is determined by the keyboard, if countersunk screws are used for connection, the minimum thickness of the keyboard tray is the depth of the groove required for the embedded keyboard plus the thickness of the bottom of the keyboard tray. In this way, the thickness of the keyboard tray can be minimized, and the material cost and machining cost of the keyboard tray can be reduced, which has important economic significance. The rotation, limit, and internal routing of the keyboard tray are realized, and the overall dust and water resistance are achieved, meeting the requirements for cleaning and disinfection of keyboard applications in operating rooms.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the embodiments of the utility model in conjunction with the accompanying drawings. It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive. Therefore, the utility model is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by technical personnel in this field based on the technical solution of the utility model also fall within the scope of protection of the utility model.

[0021] like Figure 2 and Figure 3 As shown, a rotary keyboard tray is composed of a mounting back plate 1, a mounting seat 2, a rotating shaft 3, an adapter block 4, a keyboard wire 5, a keyboard tray 6, a screw 7, a keyboard 8, and a threaded cover 9. Among them, the mounting seat 2 is fixed on the mounting back plate 1, the keyboard tray 6 is fixed on the adapter block 4 by screws 7, the adapter block 4 is connected to the mounting seat 2 by the rotating shaft 3, and the threaded cover 9 is fixed on the adapter block 4.

[0022] like Figure 4 As shown, the top surface of the adapter block 4 is provided with a threaded hole and a top through hole, the left and right sides are provided with side through holes, and the front is provided with an internal main through hole; wherein the internal main through hole is drilled from the front of the adapter block 4, connecting the top through hole and the side through hole; a thread is provided at the outlet of the internal main through hole, which is connected to the threaded cover 9.

[0023] like Figure 2 and Figure 3 As shown, a rotating keyboard tray has the following internal wiring path: the keyboard wire 5 passes through the bottom through hole of the keyboard tray 6, enters the top through hole of the adapter block 4, passes through the main through hole inside the adapter block 4, comes out from the side through hole of the adapter block 4, enters the internal through hole of the rotating shaft 3, and then passes through the side through hole of the mounting seat 2 to enter the back through hole of the mounting seat 2, and finally passes through the through hole of the mounting back plate 1 to connect with the device.

[0024] Compared with the rotating keyboard tray with a left-middle-right structure, the utility model has multiple wire bends of about 90 degrees when routing internally, namely, the keyboard wire 5 passes through the bottom through hole of the keyboard tray 6 and enters the top through hole of the adapter block 4; the keyboard wire 5 enters the main through hole inside the adapter block 4 from the top through hole of the adapter block 4; the keyboard wire 5 passes through the main through hole inside the adapter block 4 and comes out from the side through hole of the adapter block 4; the keyboard wire 5 passes through the side through hole of the mounting seat 2 and enters the back through hole of the mounting seat 2. Therefore, while designing the structure, the feasibility of the actual assembly operation must be considered. Considering that there are two wire bends of about 90 degrees in the adapter block 4, and only one wire bend of about 90 degrees in the other parts, the following focuses on the internal routing scheme of the adapter block 4. First, the main through hole inside the adapter block 4 is the intersection of the two 90-degree bends of the internal routing of the adapter block 4, so setting its aperture larger is conducive to routing. In a design example, the main through hole inside the adapter block 4 is designed to be 15 mm in diameter. In addition, the through hole at the top of the adapter block 4 is set to be close to the outlet of the main through hole inside the adapter block 4 on the front. When routing, the keyboard wire 5 is first passed through the outlet of the main through hole inside the adapter block 4 on the front, and then passed into the adapter block 4 from the outlet of the main through hole inside the adapter block 4 on the front after bending, and then passed out from the through hole at the top of the adapter block 4. The advantage of this design is that the diameter of the wire is generally smaller than that of the wire connector, and the wire is easier to bend than the wire connector, which is more convenient for perforation and routing operations.

[0025] like Figure 2 As shown, the keyboard 8 is embedded in the square groove set on the top of the keyboard tray 6 around its periphery, and the top of the keyboard 8 has a flange to cover the gap between the keyboard 8 and the square groove of the keyboard tray 6, and sealing is achieved by applying glue at the gap.

[0026] like Figure 5 As shown, the keyboard tray 6 drives the adapter block 4 to rotate upward relative to the mounting seat 2 through the rotating shaft 3, and the back of the keyboard tray 6 contacts the top of the mounting seat 2, and the rotation stroke is limited.
