Description

Technical Field

[0001] The present invention relates to the technical field of qin body processing equipment, and specifically belongs to a multi-angle positioning guqin processing placement rack. Background Art

[0002] In the manual production process of guqin, especially after the formation of the qin body structure, operations such as sanding, wrapping with cloth, applying ash, and applying lacquer need to be carried out on the qin body to protect the wooden structure of the guqin, extend its service life, and at the same time endow the guqin with unique luster and charm, making it more artistic value. However, in the specific operation process, how to stably support the guqin so that it is convenient for craftsmen to apply paint evenly, avoid paint dripping, and can conveniently inspect the paint surface has always been a technical problem. Taking the application of large lacquer as an example, the existing operation methods mostly use direct painting. After painting one side, the qin body is turned over and placed on the operating table for the next side operation. This method not only has low construction efficiency and requires waiting for the previous paint surface to dry before proceeding to the next step, but also inevitably damages the paint surface at the place directly contacting the operating table during painting. More importantly, since the whole qin surface is an arc surface towards its two sides, paint dripping is likely to occur on both sides after painting, so it is necessary to frequently inspect and repair. Therefore, it is extremely important to design a bracket that can suspend the qin body and facilitate flipping for pure hand-made guqin processing. Summary of the Invention

[0003] To solve the above problems, the present invention designs a multi-angle positioning guqin processing placement rack, which can support the qin body, realize quick flipping and fixing at any angle, and at the same time make clever use of the qin body structure, and the clamping points are all located at the places where the qin body does not need to be operated, so that operations such as painting the qin body can be completed with a single installation of the qin body.

[0004] To achieve the above object, a multi-angle positioning guqin processing placement rack of the present invention adopts the following technical solutions: It includes a support frame and fixing components arranged at both ends of the support frame. The fixing components include a first fixing component and a second fixing component. The fixing components are both in a U-shaped structure. There are support rods on the fixing components and they are rotatably installed on the support frame through bearing sleeves, and the two support rods are coaxially arranged; on the two cross bars of the fixing components, a spiral fixing group and a supporting member are respectively arranged. The spiral fixing group includes a threaded rod penetrating the cross bar and a butterfly handle and a gasket respectively located at both ends of the threaded rod. There are threaded holes on the cross bar, and the threaded rod penetrates the threaded hole; the supporting member of the second fixing component is fixed to the cross bar where it is located through a supporting rod; a positioning clip is arranged on the support rod of any one of the fixing components.

[0005] As a further improvement of the multi-angle positioning guqin processing placement rack of the present invention: The support rod of the fixing component is located on the outer side of the vertical rod of the U-shaped structure, and the support rod of the first fixing component is slidably arranged in the bearing sleeve.

[0006] As a further improvement of the multi-angle positioning guqin processing and placement rack described in the present invention: The positioning clamp includes two semi-circular fixing sleeves sleeved on the support rod. One end of the two fixing sleeves is rotatably connected, and the other end is connected by a screw. One of the fixing sleeves is fixed on the support frame, and a silica gel anti-slip pad is arranged on the inner side of the fixing sleeve.

[0007] As a further improvement of the multi-angle positioning guqin processing and placement rack described in the present invention: A slideway is arranged on the inner wall of the bearing sleeve at the first fixing component along its thickness direction, and a strip-shaped protrusion is arranged on the support rod of the first fixing component and is used in cooperation with the slideway in the bearing sleeve.

[0008] As a further improvement of the multi-angle positioning guqin processing and placement rack described in the present invention: The spiral fixing group and the supporting member are both located at the end of the cross bar where they are located. And the length of the cross bar of the second fixing component is much greater than the width of the guqin forehead, the length of the supporting rod is greater than 20 cm, and the length of the vertical rod in the second fixing component is greater than 47 cm.

[0009] As a further improvement of the multi-angle positioning guqin processing and placement rack described in the present invention: The supporting member of the first fixing component is fixed on the end face of the cross bar where it is located. The transverse surface of the supporting member is of a concave structure, and the two corners of the transverse surface are inclined along the direction of the guqin crown angle.

[0010] As a further improvement of the multi-angle positioning guqin processing and placement rack described in the present invention: The gasket in the spiral fixing group of the second fixing component is a U-shaped groove for clamping the guqin yueshan. The upper side of the U-shaped groove is rotatably connected with the threaded rod; the supporting member of the second fixing component is a strip-shaped structure perpendicular to the cross bar.

[0011] As a further improvement of the multi-angle positioning guqin processing and placement rack described in the present invention: A lighting device is arranged on the support frame.

[0012] Compared with the prior art, the multi-angle positioning guqin processing and placement rack described in the present invention has the following beneficial effects: For the multi-angle positioning guqin processing and placement rack described in the present invention, the guqin to be processed is suspended by the support frame, which is convenient for operations such as grinding, wrapping cloth, and painting. Compared with the prior art of directly painting the guqin placed on the operating table, it can effectively avoid damaging the already painted surface when painting other surfaces of the guqin body; at the same time, the rotatable design of the fixing component of the placement rack is convenient for quickly and harmlessly rotating the guqin body, which is convenient for the operator to inspect and repair the overall guqin surface.

[0013] The multi-angle positioning guqin processing and placement rack described in the present invention. The positioning clips on the support rods can fix the guqin body at any angle, facilitating the operator's construction. The bolt-type fixing method of the fixing clips is convenient for the operator to operate. The silica gel anti-slip pads in the positioning clips increase the friction between the support rods and the positioning clips, ensuring the stability of the positioning angle of the guqin body.

[0014] The multi-angle positioning guqin processing and placement rack described in the present invention. The first fixing component is slidably arranged on the support frame through the cooperation of the slideway and the strip-shaped protrusion. By pushing the first fixing component left and right, the distance between the first fixing component and the second fixing component can be adjusted, so that the device can be suitable for clamping guqin bodies of different lengths. At the same time, the design of the bearing sleeve ensures the rotation of the first fixing component in its axial direction.

[0015] The multi-angle positioning guqin processing and placement rack described in the present invention. Movable spiral fixing groups and fixedly arranged supporting members are provided in the fixing components. Among them, the spiral fixing group rotates on the cross bar of the fixing component through the screw rod, and the distance between the gasket on it and the supporting member can be adjusted, that is, the clamping and releasing of the guqin body are realized. Moreover, the length of the cross bar in the second fixing component is much larger than the width of the guqin forehead, and the lengths of the supporting rod and the vertical rod in the second fixing member are designed to ensure that there is at least a 20 cm construction space between each strut of the second fixing component and the side and end faces of the guqin body, ensuring that the device can realize one-time and gapless operation on all sides of the guqin body when in use, greatly improving the construction efficiency of the operator.

[0016] The multi-angle positioning guqin processing and placement rack described in the present invention. The concave structure design on the horizontal surface of the supporting member in the first fixing component, that is, it corresponds to the crown angle of the guqin body; the gasket in the first fixing component is placed on the crown angle; the gasket in the second fixing component is a U-shaped groove and can be smoothly clamped on the yueshan of the guqin body; the supporting member in the second fixing component corresponds to the zhenchi of the guqin body, and this supporting member is a strip-shaped structure to increase its contact area with the guqin body and improve the clamping stability. More importantly, since the crown angle, yueshan and zhenchi of the guqin body do not need to be painted with lacquer, the clamping positions of the fixing components are located at both ends of the guqin body and cleverly avoid the positions to be constructed on the guqin body, improving the clamping stability without repeatedly adjusting the clamping positions.

[0017] The multi-angle positioning guqin processing and placement rack described in the present invention can be equipped with lighting equipment with multi-angle adjustment to facilitate the inspection of grinding and the flatness of the paint surface, improving the construction effect.

Detailed implementation mode

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and gives a detailed implementation method. Embodiment 1

[0020] A multi-angle positioning guqin processing and placement rack according to the present invention includes a support frame 1 and fixing components arranged at both ends of the support frame 1. The support frame 1 is an I-shaped base and a vertical rod fixed above the base. The fixing components are installed at the upper end of the vertical rod through a bearing sleeve 101. The fixing components include a first fixing component 2 and a second fixing component 3. The first fixing component 2 is used to clamp the tail end of the guqin body, and the second fixing component 3 is used to clamp the forehead end of the guqin body.

[0021] Both of the two fixing components are in a U-shaped structure. A support rod 201 is arranged on the outer side of the vertical rod of the fixing component. The fixing component is rotatably mounted on the support frame 1 through a bearing on the vertical rod of the support frame 1, and the two support rods 201 are coaxially arranged to ensure that after the piano body is clamped, the two fixing components and the piano body rotate as a whole. The diameter of the support rod 201 at the first fixing component 2 is smaller than the inner diameter of the bearing on its corresponding vertical rod, that is, it is ensured that the support rod 201 can slide freely left and right in the bearing, so that the device is applicable to clamping piano bodies of different lengths. Spiral fixing groups and supporting members 205 are respectively arranged on the two cross bars of the fixing component. In the present invention, the spiral fixing groups and the supporting members 205 are both located at the ends of their corresponding cross bars. The spiral fixing group includes a threaded rod 202 passing through the cross bar, and a butterfly handle 204 and a gasket 203 respectively located at both ends of the threaded rod 202. A threaded hole is provided on the cross bar, and the threaded rod 202 passes through the threaded hole; the supporting member 205 of the second fixing component 3 is fixed to its corresponding cross bar through a supporting rod 302. The length of the cross bar of the second fixing component 3 is much larger than the width of the forehead of the guqin, ensuring that after the piano body is clamped, there is an operating space between the end face of the forehead of the piano body and the vertical rod of the second fixing component 3. The length of the supporting rod 302 is greater than 20 cm, and the length of the vertical rod in the second fixing component 3 is greater than 47 cm. In the present invention, the length of the supporting rod 302 is set to be greater than 20 cm to ensure that after the device clamps the piano body, there is an operating space reserved between the bottom surface of the piano body and the cross bar of the second fixing member; the length of the vertical rod is greater than 47 cm, that is, after the piano body is clamped, it is ensured that the distance between the piano surface and the cross bar where the threaded rod 202 in the second fixing component 3 is located is greater than 20 cm, and the operating space above the piano surface is also ensured. The length design of the second fixing component 3 here is because various surfaces at the forehead on the yueshan side of the piano body also need to be polished, painted, etc. By reserving an operating space, it is convenient to process the piano body after it is clamped.

[0022] A positioning clamp 4 is arranged on the support rod 201 of any one of the fixing components. In this embodiment, the positioning clamp 4 can be arranged on the support rod 201 of the second fixing component 3. The positioning clamp 4 includes two semi-circular fixing sleeves 401 sleeved on the support rod 201. One end of the two fixing sleeves 401 is rotatably connected, and the other end is connected by a screw. One of the fixing sleeves 401 is fixed to the support frame 1. This structural design can ensure that after the positioning clamp 4 is clamped on the support rod 201, the angle of the fixing component is fixed, so as to facilitate the operator's construction and processing. A silica gel anti-slip pad is arranged on the inner side surface of the fixing sleeve 401 to improve the anti-slip coefficient.

[0023] The transverse surface of the supporting member 205 of the first fixing component 2 is of a concave structure, and the two corners of the transverse surface are inclined along the direction of the guqin crown angle; the gasket 203 in the spiral fixing group of the second fixing component 3 is a U-shaped groove 301 for clamping the yueshan of the guqin. There is a rotational connection between the bottom surface of the U-shaped groove 301 and the threaded rod 202. Specifically, the threaded rod 202 penetrates through the bottom surface of the U-shaped groove 301, and clamping rings are arranged on both sides of the end of the threaded rod 202 at the bottom surface of the U-shaped groove 301. The U-shaped groove 301 is rotationally installed at the end of the threaded rod 202 through the clamping rings; the supporting member 205 of the second fixing component 3 is a strip-shaped structure perpendicular to the cross bar. In this embodiment, the gasket 203 in the first fixing component 2 is placed on the crown angle; the gasket 203 in the second fixing component 3 is a U-shaped groove 301, which can be smoothly clamped on the yueshan of the guqin body; the supporting member 205 of the second fixing component 3 corresponds to the zhenchi design of the guqin body, and this supporting member 205 is a strip-shaped structure to increase its contact area with the guqin body and improve the clamping stability; more importantly, since there is no need to apply lacquer or other operations inside the crown angle, yueshan and zhenchi of the guqin body, the clamping positions of the fixing components are located at both ends of the guqin body and cleverly avoid the construction positions to be processed on the guqin body, improving the clamping stability without repeatedly adjusting the clamping positions. Embodiment 2

[0024] In this embodiment, the specific structure of the multi-angle positioning guqin processing and placing rack is basically the same as that of the multi-angle positioning guqin processing and placing rack in Embodiment 1. The difference lies in that: a slideway is arranged on the inner wall of the bearing sleeve 101 at the first fixing component 2 along its thickness direction, and a strip-shaped protrusion 102 is arranged on the support rod 201 of the first fixing component 2 for cooperating with the slideway in the bearing sleeve 101; a lighting device is arranged on the support frame 1, and an installation groove for placing the battery of the lighting device and a circuit control switch for the lighting device are arranged on the support frame 1. A flexible tube is sleeved outside the wire between the lamp head of the lighting device and the battery. By adding a lighting device, it is convenient to check the grinding and the flatness of the paint surface to improve the construction effect.
