[0033] It should be understood that the drawings are only used to easily understand the disclosed embodiments in the specification, and do not limit the technical concept disclosed in the specification by the drawings, and should include all modifications, equivalents and even alternatives included in the concept and technical scope of the present application. The constituent elements in the drawings can be excessively enlarged or reduced in size or thickness for the convenience of understanding, but this does not limit the explanation of the protection scope of the present application.

[0034] The terminology used in the present specification is for the purpose of describing particular implementations only and is not intended to limit the present application. In this specification, the terms "comprise", "comprising", "consist", "consisting", "consisting essentially of" and like terms are intended to specify the presence of stated features, integers, steps, operations, elements, components, devices, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, devices, or combinations thereof.

[0035] Hereinafter, the present application will be described in detail with reference to the accompanying drawings.

[0036] Reference Figures 1-5 The music stand expander of the present application comprises a connecting piece 1 and an expansion plate piece 2. The connecting piece 1 can be detachably connected to the music stand and has a running channel 1-1 arranged along its length direction. In particular, in the present embodiment, the detachable connection can be achieved by adhesion, for example, an adhesive material is formed on the bottom of the connecting piece 1 to adhere to the bottom baffle (not shown) at the front wall of the music stand, so that the connecting piece 1 can be fixed in position by adhesion when needed. Specifically, the connecting piece 1 is usually adhered to the middle position of the bottom baffle.

[0037] In the present embodiment, the connecting piece 1 is spliced by sheet metal parts, and the connecting piece 1 has an upper top plate 1-2, a side plate 1-3, and a lower bottom plate 1-4. The upper top plate 1-2, the side plate 1-3, and the lower bottom plate 1-4 jointly form the running channel 1-1, and the running channel 1-1 is open at both ends along its length direction to facilitate the convenient insertion of components into the end. Further, the lower bottom plate 1-4 extends outward along the depth direction of the running channel 1-1 by a distance greater than the distance by which the upper top plate 1-2 extends outward along the depth direction of the running channel 1-1, thereby increasing the width of the lower bottom plate 1-4 and thus increasing the adhesion area to make the adhesion more secure and reliable. In actual adhesion, the running channel 1-1 of the connecting piece 1 is adhered towards the front wall of the music stand.

[0038] As an important component that can expand the size of the music stand (not shown), the number of the expansion plate pieces 2 can be one, two, three, etc., but at least one, and in the present embodiment, two oppositely arranged ones are preferred. Each expansion plate piece 2 has an expansion plate body 2-1 that can be detachably connected to the music stand, and the expansion plate piece 2 further has a guide piece 2-2 that can be inserted into the running channel 1-1 and can move along the running channel 1-1 to drive the expansion plate piece 2 to run.

[0039] The guide 2-2 is arranged along the bottom of the expansion plate body 2-1 and is configured as a long strip plate structure and protrudes from the front wall of the expansion plate body 2-1. When assembled, after the connecting piece 1 is bonded to the bottom baffle of the spectrum plate, the opening of the running channel 1-1 is away from the front wall at the bottom of the spectrum plate by a certain distance, thereby leaving a certain spacing space, so that the guide 2-2 can be sleeved from the end of the running channel 1-1, and then the expansion plate 2 can be moved back and forth along the running channel 1-1. During the movement, although there is the above-mentioned spacing space, after the guide 2-2 is sleeved, the back of the expansion plate body 2-1 is basically close to the front wall of the spectrum plate, so that the guide 2-2 will not come out of the running channel 1-1 during the movement of the expansion plate 2.

[0040] In the embodiment, the expansion plate body 2-1 is provided with an adsorption structure for adsorbing the spectrum plate front wall to achieve that the expansion plate body 2-1 can be detachably connected to the spectrum plate. Specifically, the adsorption structure includes a magnetic block (not shown) arranged in the expansion plate body 2-1. In order to achieve the installation of the magnetic block, the expansion plate body 2-1 is provided with an installation slot 3 at the front wall, the magnetic block is contained in the installation slot 3, and the installation slot 3 is provided with a cover 4 clamped at the opening. As to how the cover 4 can be clamped to the installation slot 3, in the embodiment, a structure of clamping legs 4-1 and clamping holes 5 is adopted to achieve this. As in the embodiment, the cover 4 is provided with clamping legs 4-1, the installation slot 3 is provided with clamping holes 5 at the side wall, and the clamping legs 4-1 are clamped in the clamping holes 5.

[0041] Specifically, the clamping legs 4-1 are provided with two, symmetrically arranged on both sides of the cover 4, and there is a gap between the side of each clamping leg 4-1 and the body of the cover 4 and the clamping legs 4-1 protrude out of the body of the cover 4 by a distance, so that the clamping legs 4-1 can achieve a slight folding action after being extruded by external force, and have a rebounding feature after the external force is removed. In addition, the clamping legs 4-1 are provided with inclined and outwardly protruding limiting front ends 4-1-1, so that when clamped in, the two clamping legs 4-1 are relatively folded after being extruded by the side wall of the clamping hole 5, and at this time, under the guidance of the inclined limiting front end 4-1-1, they can smoothly enter the clamping hole 5, and after passing through the clamping hole 5, the clamping legs 4-1 can rebound to the original position, and at this time, the limiting front end 4-1-1 passing through the clamping hole 5 will be limited on the back of the expansion plate body 2-1 at the clamping hole 5, thereby achieving that the cover 4 is clamped in the installation slot 3.

[0042] It should be noted that in order to maintain the flatness of the front wall of the expansion plate body 2-1, the cover 4 is clamped in the installation slot 3, and the cover 4 is flush with the front wall of the expansion plate body 2-1, without protruding outward, which is beneficial to use.

[0043] In order to increase the overall strength of the plate body 2-1, the plate body 2-1 is provided with longitudinal and transverse intersecting reinforcing ribs 6 on the back thereof. The back of the mounting groove 3 protrudes from the back of the plate body 2-1 and is flush with the back of the reinforcing ribs 6.

[0044] In order to prevent the plate body 2-1 from scratching the spectrum plate when it is moved, the back of the mounting groove 3 is provided with an embedded groove 7 at the upper and lower ends thereof for mounting a rubber protective pad 1 (not shown), and the back of the plate body 2-1 is provided with an embedded groove 8 for mounting a rubber protective pad 2 (not shown). The embedded groove 8 extends across the back of the plate body 2-1 and reaches the back of the mounting groove 3, thereby forming a longitudinal and transverse rubber protective pad which can protect the front wall of the spectrum plate from being scratched.

[0045] It should be noted that in the present embodiment, the plate body 2 is provided in pairs, including a first plate body (not labeled) and a second plate body (not labeled) which are arranged opposite to each other. The suction structure is arranged close to the opposite sides of the first plate body and the second plate body, respectively.

[0046] In order to increase the strength of the plate body 2-1 at the edges thereof, the back of the plate body 2-1 is provided with edge reinforcing ribs 9 which protrude from the back thereof along the edges. The edge reinforcing ribs 9 are flush with the reinforcing ribs 6. It can be seen that the back of the plate body 2-1 remains flat after the various reinforcing ribs are arranged thereon and does not protrude arbitrarily.

[0047] In order to facilitate operation during the process of inserting and taking out, the edge reinforcing ribs 9 on the outer side of the plate body 2-1 continue to protrude by a certain distance to form edge reinforcing rib plates 10. That is, the width of the edge reinforcing rib plates 10 is greater than the width of each reinforcing rib plate. When the plate body 2-1 is moved, the edge reinforcing rib plates 10 can be gripped at this position. Meanwhile, the edge reinforcing rib plates 10 continue to extend downward and are connected to the outer end of the guide member 2-2. Thus, the plate body 2-1 can be limited and prevented from being inserted excessively.

[0048] In use, the connecting member 1 is attached to the middle position of the bottom baffle of the spectrum plate. Then, the two plate bodies 2 are inserted into the connecting member 1 from the two ends thereof, respectively. Then, the plate bodies 2 are moved to the appropriate position to expand the size of the spectrum platform. Then, the plate body 2-1 is attracted to the spectrum plate by the magnetic block to prevent the plate body 2-1 from being displaced. When it is necessary to adjust the position of the plate body 2-1, the plate body 2-1 is slightly tilted outward to release the attraction of the magnetic block. Then, the position of the plate body 2-1 can be adjusted along the running channel 1-1.

[0049] The embodiments of the present application are described above with reference to the accompanying drawings, but the present application is not limited to the specific embodiments described above, and the specific embodiments described above are merely illustrative, but not restrictive, and a person of ordinary skill in the art can make many forms under the inspiration of the present application without departing from the purpose of the present application and the scope protected by the claims.
