Description

TECHNICAL FIELD The present invention belongs to the technical field of musical instruments, and more particularly, to an electric piano whose height can be easily adjusted and which is used integrally with a desk.

With the improvement of living standards, pianos are universally entering ordinary households. Especially in recent years, the development speed of the electric piano is very fast, and the keyboard of the electric piano is usually mounted on a supporting frame for use because of its simplicity and portability. Generally, the support frame is often installed in an H-shape or an X-shape. Since the current support frame remains constant in height, for young or tall people, the height of a normal fixed support frame cannot meet the commonly used requirements.

On the other hand, in the technology of the present application, research and development are being conducted on the problem of electric piano stands that are currently on the market. The stand of the electric piano is integrally mounted and fixed, that is, the height of the electric piano remains unchanged after the mounting is completed. Therefore, there are the following disadvantages in use. When used by children of different heights or used by adults, the overall height of the electric piano is fixed, and the height of the piano stand cannot be adjusted according to the height of the user, so that children can use it. In some cases, the piano chair is too high for both feet to reach the ground, or the piano chair is too low for both hands to reach the keyboard, in order to match the fixed height of the electric piano. On the other hand, the technology of the present application solves the problem that not all electric pianos can be integrated with the desk at present, and that the electric piano is simple and used only as a musical instrument.

SUMMARY OF THE INVENTION An object of the present invention is to overcome the drawbacks of the prior art by providing an electric piano that has a rational design, can be adjusted according to the user's height requirements, and can be used integrally with a desk. .

The present invention is realized by the following technical means. A height-adjustable desk-type electric piano composed of a holder body and a desk-type keyboard unit attached to the holder body, wherein the holder body is provided with an adjustment device for adjusting the elevation of the holder body. A desk-type electric piano with an adjustable height.

The desk-type keyboard unit includes a table surface of a desk and a piano keyboard connected as a drawer within the table surface of the desk and capable of being pulled out and retracted.

The adjustment device includes a handle, a rotating rod connected to the handle and rotating, a disk gear fixed to the rotating rod, a sleeve rod, and a sleeve rod that is fitted into and connected to the sleeve rod by screwing and is screwed in the sleeve rod, A lead screw adjuster including a threaded rod that is unscrewed.

A vertical gear is provided on the top of the threaded rod to engage and connect with the disc gear to transmit power.

The holder body is installed symmetrically, and includes a support rod unit that is a telescopic fit rod, a sleeve rod and a threaded rod in the lead screw adjusting device are mounted in the telescopic fit rod, and a rotating rod straddles the tops of the two support rod units and is driven to extend or shorten the telescopic sleeve rod after the threaded rod is screwed in and out of the sleeve rod.

As an effect of the present invention, compared with the prior art, the screw rod is driven in and out of the sleeve rod by gear transmission in the stand of the electric piano according to the invention, The inner rod can be telescopically moved within the outer rod, and the piano stand can be adjusted up and down to meet the needs of people of different heights. Then, it may be integrated with the structure of the desk and used as an electric piano or as a desk.

The present invention will be described in detail below with reference to the drawings.

FIG. 3 is an enlarged schematic diagram of a portion A in FIG. 2 ; FIG. 4 is a schematic diagram of a gear meshing state in the present invention; FIG. 4 is a schematic diagram showing the height of the present invention is adjusted to a high point and the piano keyboard is pulled out; FIG. 4 is a schematic diagram showing the height of the present invention is adjusted to the low point and the piano keyboard is pulled out; FIG. 4 is a schematic diagram showing the height of the present invention is adjusted to a high point and the piano keyboard is closed to form a desk; FIG. 4 is a schematic diagram showing that the height of the present invention is adjusted to the low point and the piano keyboard is closed to form a desk;

The technical means in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some, but not all embodiments of the present invention.

In Example 1, reference is made to FIGS. A height-adjustable desk-type electric piano consists of a holder body and a desk-type keyboard unit attached to the holder body. there is

The desk-type keyboard unit includes a desk table surface 12 and a piano keyboard 13 connected as a drawer within the desk table surface 12 and capable of being pulled out and retracted. The piano keyboard 13 is an electric piano keyboard or an electronic organ keyboard. A music stand can be installed on the table surface of the desk as required so as not to affect the use of the table surface of the desk as a flat surface.

The holder body comprises telescoping rods, in particular an inner rod 4 and an outer rod 5, placed symmetrically. The inner rod 4 is fitted into the outer rod 5, and the holder body is provided with a lead screw adjusting device for adjusting the elevation of the holder body.

The lead screw adjusting device includes a handle 1, a rotating rod 3 connected to the handle 1 and rotating, a disk gear 10 fixed to the rotating rod 3, a sleeve rod 9, and a sleeve rod 9 fitted and connected by screws. , a threaded rod 8 which is screwed in and out of the sleeve rod 9 .

As shown in FIG. 4, the disc gear 10 is mounted inside the gear housing 7 . The number of gear housings 7 is two, each fixed to the top of the symmetrical internal rod 4 , the rotating rod 3 passes through the left and right disk gears 10 respectively, and the handle 1 is attached to one end of the rotating rod 3 . Fixed.

As shown in FIGS. 3 and 4, a vertical gear 11 is provided on the top of the threaded rod 8 and engages with a disk gear 10 to transmit power. The threaded rod 8 is screwed in and out within the sleeve rod 9 , which is inserted inside the inner rod 4 , the outer rod 5 and the fixed rod 6 . The lower end of sleeve rod 9 is fixedly attached to the bottom surface of fixed rod 6 . When the handle 1 rotates, the longitudinal gear 11 is driven to mesh with the disk gear 10 and drive the threaded rod 8 into and out of the sleeve rod 9 . Since the lower end of the sleeve rod 9 is fixed, the inner rod 4 can be further drawn out and retracted within the outer rod 5 to achieve the purpose of lifting. As shown in FIGS. 5 and 6, the handle is turned to raise the desk-type keyboard unit to the highest point or the lowest point, and the keyboard 13 of the piano can be pulled out from the table surface 12 of the desk and played. As shown in FIGS. 7 and 8, the keyboard 13 of the piano is closed, the handle is turned, and the desk-type keyboard unit is raised to the highest or lowest point so that it can be used as a desk.

Said external rod 5 is attached to a fixed rod 6, which is supported on the floor and plays a stabilizing role.

An L-shaped angle iron 2 is further provided on the top of the inner rod 4 so that the keyboard of the electric piano or the keyboard of the electronic organ can be more stably placed on the piano stand.

The structure design of the present invention is reasonable. In the electric piano stand, the threaded rod 8 and the sleeve rod 9 are installed inside the inner rod 4 and the outer rod 5 so that the threaded rod 8 can be screwed in and out of the sleeve rod 9 . The power for screwing in and out is derived from the power transmitted by manually moving the handle 1 to mesh the vertical gear 11 and the disc gear 10 with each other. After the inner rod 4 rises or falls within the outer rod 5, the keyboard mounted on its top also rises or falls accordingly, thus achieving the purpose of adjusting the height of the stand of the electric piano.

Of course, the adjustment device may also be a plug-type self-locking adjustment that manually slips the large rod over the small rod.
