Description

Technical Field

[0001] This utility model relates to the field of host brackets, and in particular to a host bracket width adjustment device. Background Technology

[0002] Desks, gaming desks, and other tables that require the use of computers need to be equipped with computer towers. The towers are usually placed under the desktop, taking up floor space. Therefore, the existing technology uses a tower bracket to fix the tower under the desktop, and then fixes the tower inside the tower bracket to achieve the purpose of tower suspension, thereby saving floor space.

[0003] CN 219655791 U discloses an adjustable computer host bracket, including an upper bracket, a width adjustment bracket, and a height adjustment bracket. The width adjustment bracket is used to adjust the width of the bracket to facilitate host installation and accommodate hosts of different widths. The width adjustment structure includes a rack, a toothed bracket, and a spring and push rod for controlling the toothed bracket. When adjusting the width, the push rod is pressed, the push rod is pushed forward, the toothed bracket is retracted, and the toothed bracket is disengaged from the rack. The position of the width adjustment bracket is adjusted as required. When the position is reached, the push rod is released, and the toothed bracket is pushed forward by the compression spring to engage with the rack, locking the width adjustment bracket. While this patent can achieve width adjustment, it has the following two problems: First, when adjusting the width, the push rod needs to be pressed continuously to keep the teeth disengaged from the rack. Pressing and width adjustment need to be done simultaneously. When the width position is repeatedly adjusted, the push rod needs to be pressed for a long time, which is quite strenuous and requires the cooperation of both hands. This is especially inconvenient for users when the main unit is installed in a small area under the desktop. Second, after the width position is adjusted, it needs to be locked with a spring, which has poor reliability. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a main unit bracket width adjustment device that is easy to adjust and highly reliable.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a main unit bracket width adjustment device, including a bracket base, a fixed upright plate on one side of the bracket base, a bottom support plate at the bottom end of the fixed upright plate, and an adjustment seat horizontally slidingly and telescopically installed on the other side of the bracket base, the bottom end of the adjustment seat having an adjustment upright plate that cooperates with the fixed upright plate; a toothed rod is fixedly provided on the bracket base, the surface of the toothed rod having a plurality of locking tooth grooves arranged along the telescopic direction of the bracket base, a rotating rod is rotatably installed on the adjustment seat, the rotating rod having locking tooth blocks corresponding to each of the locking tooth grooves, an adjustment knob is fixedly connected to one end of the rotating rod, the adjustment knob having a limiting post, the adjustment seat having an arc-shaped hole, the limiting post being inserted into the arc-shaped hole and sliding along the arc-shaped hole, when the limiting post slides to the end point of the arc-shaped hole, the locking tooth block is inserted into the locking tooth groove.

[0006] As a preferred technical solution, the bracket seat is provided with a transverse sliding groove, and the adjusting seat moves back and forth along the transverse sliding groove.

[0007] As a preferred technical solution, the locking tooth block is provided in two parts, which are respectively arranged on both sides of the rotating rod.

[0008] As a preferred technical solution, the arc-shaped hole is a semi-circular arc, and the two ends of the semi-circular arc correspond to the positions of the two locking tooth blocks respectively.

[0009] As a preferred technical solution, a damping ring is provided between the outer periphery of the rotating rod and the adjusting seat.

[0010] As a preferred technical solution, the end of the rotating rod is provided with a groove, the end of the adjusting knob is provided with a protrusion that fits into the groove, and the adjusting knob is fixed to the end of the rotating rod by a screw.

[0011] As a preferred technical solution, the outer surface of the adjustment knob is provided with an indicator mark.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: This utility model provides a width adjustment device with pure mechanical locking. Compared with the locking method using springs, the locking effect of this pure mechanical device is better. It uses a semi-circular guide groove to limit the locking position, which plays a self-locking role, resulting in better locking effect and higher reliability. Moreover, after unlocking, it will remain in the unlocked state, and the user does not need to continuously press or rotate to unlock. At this time, the width can be adjusted arbitrarily. After the width is repeatedly adjusted, it can be locked again. This adjustment and unlocking do not need to be operated simultaneously. Unlocking and adjustment can be completed with one hand, which is more conducive to user operation and suitable for operation in confined spaces. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0016] like Figures 1 to 8As shown, a host computer bracket width adjustment device includes a bracket base 1, which serves as the mounting base for the device and is installed under a desktop. A fixed upright plate 2 is provided on one side of the bracket base 1, and a bottom support plate 3 is provided at the bottom end of the fixed upright plate 2. An adjustment seat 4 is horizontally and slidably mounted on the other side of the bracket base 1. An adjustment upright plate 5, which cooperates with the fixed upright plate 2, is provided at the bottom end of the adjustment seat 4. The distance between the adjustment upright plate 5 and the fixed upright plate 2 is the required width of the host computer bracket. The top end of the adjustment upright plate 5 is fixed to the bottom end of the adjustment seat 4. A toothed rod 6 is fixedly provided on the bracket base 1, and the toothed rod 6 is arranged along the extension direction of the bracket base 1. The surface of the toothed rod 6 is provided with a plurality of locking toothed grooves 7 along the extension and retraction direction of the bracket seat 1. A rotating rod 8 is rotatably mounted on the adjusting seat 4. Both ends of the rotating rod 8 are rotatably supported on the adjusting seat 4. The outer periphery of the rotating rod 8 is provided with locking tooth blocks 9 corresponding to each of the locking toothed grooves 7. One end of the rotating rod 8 extends into the outside of the adjusting seat 4 and is fixedly connected to an adjusting knob 10. The adjusting knob 10 is provided with a limiting post 11. The adjusting seat 4 is provided with an arc-shaped hole 12. The limiting post 11 is inserted into the arc-shaped hole 12 and slides along the arc-shaped hole 12. When the limiting post 11 slides to the end point of the arc-shaped hole 12, the locking tooth block 9 is inserted into the locking toothed groove 7.

[0017] The bracket seat 1 is provided with a transverse sliding groove, and the adjusting seat 4 moves back and forth along the transverse sliding groove. The transverse sliding groove can ensure the stability of the adjusting seat 4 during transverse adjustment.

[0018] The locking tooth block 9 has two parts, which are respectively arranged on both sides of the rotating rod 8 at a 180-degree angle.

[0019] The arc-shaped hole 12 is a semi-circular arc, and the two ends of the semi-circular arc correspond to the positions of the two locking tooth blocks 9 respectively. The semi-circular arc is 180°. When the limiting post 11 slides to 0° and 180°, the two locking tooth blocks 9 can be inserted into the locking tooth groove 7 respectively and are in a locked state. When the limiting post 11 approaches the 90° position, the locking tooth block 9 separates from the locking tooth groove 7 and is in an unlocked state. The limiting post 11 can be locked by rotating 90° clockwise or counterclockwise from the unlocked state.

[0020] A damping ring is provided between the outer periphery of the rotating rod 8 and the adjusting seat 4. The damping ring is used to control the rotation of the rotating rod 8, ensuring that the rotating rod 8 can rotate and requires a certain force when rotating, so that the adjusting knob 10 can remain stationary in the locked position when the adjusting knob 10 is not rotated.

[0021] The end of the rotating rod 8 is provided with a groove, and the end of the adjusting knob 10 is provided with a protrusion that fits into the groove. The adjusting knob 10 is fixed to the end of the rotating rod 8 by screws. When the adjusting knob 10 is installed, the angle of adjustment is determined by the engagement of the protrusion with the groove, and then it is fixed by screws.

[0022] The outer surface of the adjustment knob 10 is provided with an indicator mark, the position of which corresponds to the position of the limit post 11.

[0023] The working principle of this embodiment is as follows: When width adjustment is required, rotate the adjustment knob 10 to make the limiting post 11 slide along the arc-shaped hole 12, which drives the rotating rod 8 to rotate, so that the locking tooth block 9 disengages from the locking tooth groove 7. At this time, stop rotating the adjustment knob 10, and then slide the adjustment seat 4 inward or outward along one side of the bracket seat 1 to change the distance between the adjustment plate 5 and the fixed plate 2, thereby achieving the purpose of bracket width adjustment. After the width adjustment is completed, rotate the adjustment knob 10 in the forward or reverse direction until the adjustment knob 10 can no longer be rotated. At this time, the limiting post 11 abuts against one end of the arc-shaped hole 12, and the locking tooth block 9 is inserted into the locking tooth groove 7 to lock and remain in the locked position.

[0024] The locking method of this application is achieved by mechanically engaging the locking tooth block 9 and the locking tooth groove 7, and by limiting the locking position with a semi-circular arc, which plays a self-locking role and ensures the locking effect.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
