The keyboard tray can be extended and retracted by the sliding cooperation of the inner and outer rails. However, this method makes it easy for snack crumbs, hair, dust and other debris to enter the track, which can easily cause it to jam during the sliding process. Utility Model Content

[0003] The purpose of this invention is to provide a keyboard tray to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a keyboard tray, including a support plate for placing a keyboard, a track assembly is fixedly installed on the lower surface of the support plate, and a clamping and adjusting mechanism for mounting the support plate on a desktop is slidably connected to the track assembly.

[0005] The track assembly includes: an annular track with a sliding groove; a mounting bracket fixedly mounted on the lower surface of a support plate by countersunk bolts, the mounting bracket being fixedly connected to the annular track by a first screw, the lower surface edge of the mounting bracket having an annular protrusion, and a limiting annular groove communicating with the sliding groove being formed between the lower surface of the annular protrusion and the upper surface of the annular track; and a movable plate slidably connected within the limiting annular groove, the movable plate having a fixed seat extending through and slidingly engaging with the sliding groove, the fixed seat having a threaded hole for connecting with a clamping and adjusting mechanism.

[0006] Preferably, the upper surface of the annular track is provided with an annular groove, and the edge of the mounting bracket is integrally formed with an annular protrusion for engaging with the annular groove.

[0007] Preferably, the mounting bracket has a plurality of protrusions integrally formed thereon, and the protrusions are provided with countersunk grooves for the heads of countersunk bolts to be engaged. The distance between the lower surface of the protrusion and the lower surface of the mounting bracket is less than the thickness of the annular protrusion.

[0008] Preferably, the clamping adjustment mechanism includes: a bracket, the lower end of which is provided with at least two first through holes, a second screw passing through the first through holes and threadedly connected to the threaded hole to fix the bracket to the fixed seat, the upper end of which is provided with a central through hole and two arc-shaped grooves; a clamping member, the lower horizontal plate of which is provided with a central screw hole and two second through holes, a pin passing through the second through holes and the arc-shaped grooves in sequence and threadedly connected to a first nut; a screw, passing through the central through hole and threadedly connected to the central screw hole, the upper end of which passes into the clamping member and is fixedly connected to a support plate, a clamping space being formed between the support plate and the upper horizontal plate of the clamping member, and a gripping block being fixedly connected to the lower end of the screw.

[0009] Preferably, the clamping member consists of an upper clamping frame and a lower clamping frame, both of which are L-shaped. The vertical plate of the lower clamping frame is provided with a set of first mounting holes, and the vertical plate of the upper clamping frame is provided with multiple sets of second mounting holes that mate with the first mounting holes. An adjusting bolt passes through the first mounting holes and the second mounting holes and is threaded with a second nut to fix the lower clamping frame and the upper clamping frame together.

[0010] Preferably, the vertical plate of the upper clamping frame protrudes outward from the middle and forms a reinforcing strip.

[0011] Preferably, the support plate consists of two flat plates, and the lower surfaces of the two flat plates are fixedly connected to multiple long strip-shaped reinforcing plates.

[0012] Preferably, a baffle protruding from the upper surface of the support plate is fixedly connected to one side of the lower surface of the two flat plates, and the baffle is provided with a notch.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. By placing the track assembly below the support plate, the ring track has a long, circular structure, and the upper opening of the ring track is covered by the mounting bracket, with only the sliding groove facing downwards. This allows most of the snack crumbs, hair, dust, etc., to slide off from the side of the track assembly, making it less likely for them to enter the track assembly. This ensures smooth sliding inside the track assembly and improves its service life.

[0015] 2. Because the track assembly adopts a double-layer structure of ring track and mounting frame, the moving plate is limited between the ring track and the mounting frame. That is, the limiting plate can only move along the length of the limiting ring groove. Since the two ends of the ring track are closed in the length direction, the moving plate can only move within a certain range. The moving plate, the fixed seat and the ring track will not separate from each other, which increases safety and service life.

[0016] 3. By setting up a clamping adjustment mechanism, when in use, first align the desktop with the clamping space, that is, the upper horizontal plate of the clamping component contacts the upper surface of the desktop, while the support plate is located below the desktop. At this time, by rotating the screw, the support plate is moved upward until it is pressed against the lower surface of the desktop, thus achieving clamping and enabling the use of the support plate. In addition, by setting an arc groove, the angle between the clamping component and the bracket can be adjusted adaptively, thereby adapting to more types of desks and improving their usage effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5 As shown, a keyboard tray includes a support plate 1 for placing a keyboard. A track assembly 2 is fixedly installed on the lower surface of the support plate 1. A clamping and adjusting mechanism 3 for mounting the support plate 1 on a desktop is slidably connected to the track assembly 2. The track assembly 2 includes an annular track 21 and a mounting bracket 22 fixedly installed on the lower surface of the support plate 1 by countersunk bolts 23. A sliding groove 211 is formed on the annular track 21. The mounting bracket 22 is fixedly connected to the annular track 21 by a first screw 24. An annular protrusion 221 is provided on the lower edge of the mounting bracket 22. A limiting annular groove 25 communicating with the sliding groove 211 is formed between the lower surface of the annular protrusion 221 and the upper surface of the annular track 21. A moving plate 26 is slidably connected to the limiting annular groove 25. A fixed seat 27 is fixedly connected to the moving plate 26, extending through the sliding groove 211 and slidingly engaging with the sliding groove 211. A threaded hole 271 for connecting with the clamping and adjusting mechanism 3 is provided on the fixed seat 27.

[0027] Understandably, by placing the track assembly 2 below the support plate 1, and given that the annular track 21 has a long, ring-shaped structure and its upper opening is covered by the mounting bracket 22, with only the sliding groove 211 facing downwards, most snack crumbs, hair, dust, etc., slide off from the side of the track assembly 2, making it less likely for them to enter the track assembly 2. This ensures smooth sliding inside the track assembly 2 and improves its service life. In addition, because the track assembly 2 adopts a double-layer structure of annular track 21 and mounting bracket 22, the moving plate 26 is limited between the annular track 21 and the mounting bracket 22. That is, the limiting plate can only move along the length of the limiting annular groove 25. Since the two ends of the annular track 21 are closed in the length direction, the moving plate 26 can only move within a certain range, preventing the moving plate 26, the fixed seat 27, and the annular track 21 from detaching from each other, thus increasing safety and service life.

[0028] As a preferred option, such as Figure 3 and Figure 5As shown, the upper surface of the annular track 21 is provided with an annular groove 212, and the edge of the mounting bracket 22 is integrally formed with an annular protrusion 222 for engaging in the annular groove 212. During assembly, the annular protrusion 222 is engaged in the annular groove 212, which can play a good positioning role, improve the connection stability between the annular track 21 and the mounting bracket 22, and facilitate the screwing in of the first screw 24.

[0029] As a preferred option, such as Figures 3-5 As shown, the mounting bracket 22 has several protrusions 223 integrally formed on it. The protrusions 223 are provided with grooves 224 for the head of the countersunk bolt 23 to be inserted. The distance between the lower surface of the protrusion 223 and the lower surface of the mounting bracket 22 is less than the thickness of the annular protrusion 221.

[0030] Understandably, the design of the protrusion 223 enables it to serve as a rigid support point, enhancing the rigidity and anti-loosening properties of the connection with the countersunk bolt 23. Furthermore, limiting the thickness of the portion of the protrusion 223 located below the mounting bracket 22 prevents interference with the sliding of the movable plate 26 in the limiting ring groove 25, thereby improving the performance.

[0031] As a preferred option, such as Figure 1 , Figure 6 and Figure 7 As shown, the clamping adjustment mechanism 3 includes a bracket 31, a clamping member, and a screw 34. The lower end of the bracket 31 is provided with at least two first through holes. A second screw 35 passes through the first through holes and is threadedly connected to the threaded hole 271 to fix the bracket 31 on the fixed seat 27. The upper end of the bracket 31 is provided with a central through hole 311 and two arc-shaped grooves 312. The lower horizontal plate of the clamping member is provided with a central screw hole 321 and two second through holes 322. A pin passes through the second through holes 322 and the arc-shaped grooves 312 in sequence and is threadedly connected to a first nut. The screw 34 passes through the central through hole 311 and is threadedly connected to the central screw hole 321. The upper end of the screw 34 passes into the clamping member and is fixedly connected to a support plate 36. A clamping space is formed between the support plate 36 and the upper horizontal plate of the clamping member. The lower end of the screw 34 is fixedly connected to a gripping block 341.

[0032] Understandably, during use, the desktop is first aligned with the clamping space, meaning the upper horizontal plate of the clamping component contacts the upper surface of the desktop, while the support plate 36 is located below the desktop. At this point, the gripping block 341 is held and rotated, which in turn drives the screw 34 to rotate synchronously, causing the support plate 36 to move upward until it presses against the lower surface of the desktop, thus achieving clamping. At this time, the support plate 1 can move along the sliding direction of the track assembly 2, allowing the keyboard to be placed on the support plate 1 for use. In addition, the design of the arc groove 312 can adaptively adjust the angle between the clamping component and the bracket 31, thereby adapting to more types of office desks and improving its usability.

[0033] As a preferred option, such as Figure 6 and Figure 7 As shown, the clamping component consists of an upper clamping frame 33 and a lower clamping frame 32. Both the upper clamping frame 33 and the lower clamping frame 32 are L-shaped. The vertical plate of the lower clamping frame 32 is provided with a set of first mounting holes, and the vertical plate of the upper clamping frame 33 is provided with multiple sets of second mounting holes 331 that mate with the first mounting holes. The adjusting bolt passes through the first mounting holes and the second mounting holes 331 and is threaded with a second nut to fix the lower clamping frame 32 and the upper clamping frame 33 together.

[0034] Understandably, by dividing the clamping component into two parts, the upper clamping frame 33 and the lower clamping frame 32, the distance between the lower horizontal plate and the upper horizontal plate of the upper clamping frame 33 can be set according to one's own conditions and preferences during assembly. This can improve the performance and enhance the user experience, as well as facilitate transportation.

[0035] As a preferred option, such as Figure 7 As shown, the upper clamping frame 33 has a reinforcing strip 332 that protrudes outward from the middle of the vertical plate, which can enhance the bending strength of the upper clamping frame 33 and improve its service life.

[0036] As a preferred option, such as Figure 2 As shown, the support plate 1 consists of two flat plates. The lower surfaces of the two flat plates are fixedly connected to multiple long strip-shaped reinforcing plates 5, which can be disassembled and stacked for convenient transportation, and can also strengthen the connection strength and bending resistance of the two flat plates after assembly, thereby improving service life.

[0037] As a preferred option, such as Figure 1 and Figure 2 As shown, a baffle 4 protruding from the upper surface of the support plate 1 is fixedly connected to one side of the lower surface of the two flat plates. This can prevent the keyboard from falling off the support plate 1. The baffle 4 has a notch 41, which can keep the connecting wires in a certain way.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
