Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of musical instrument tuning, in particular to a musical instrument tuning device. Background Art
[0002] The sound of stringed instruments is produced by mechanical force to make the tensioned strings vibrate, so the sound volume is subject to certain restrictions. Stringed instruments usually use different strings to play different notes, and sometimes the length of the strings must be changed by pressing the strings with fingers to achieve the purpose of changing the pitch. The guitar is a stringed instrument that produces sound by plucking the strings one by one. The tightness of the strings directly affects the timbre and tone of the sound. When playing, one hand plucks the strings and the fingers of the other hand rest on the fingerboard, which is a small metal strip covering the neck of the guitar. The sound produced by the plucking will be enhanced through the resonance box of the guitar.
[0003] The tuning is one of the important metal parts on the guitar. Its core parts are an adjustment mechanism composed of a handle, a worm wheel, a worm, a worm wheel bushing, and a shaft. The worm wheel is driven by rotating the handle to rotate the worm, which in turn drives the worm wheel to rotate, and the worm wheel drives the shaft to rotate to control the rotation of the string post, thereby adjusting the tightness of the strings and then adjusting the pitch. However, in the prior art, no washers are set between the worm wheel and the shaft, and between the worm wheel bushing and the worm to increase damping. During use, it is found that the entire adjustment mechanism is too loose, which will cause the tuning feel to deteriorate and affect the tuning effect. Utility Model Content
[0004] The utility model aims to provide a musical instrument tuning device to solve the problem that the tuning feel is deteriorated and the tuning effect is affected in the prior art.
[0005] In order to achieve the above object, the utility model provides the following technical solutions:
[0006] A musical instrument tuning device comprises a shaft, a worm wheel, a bottom plate, a worm shaft sleeve and a worm, wherein the bottom plate is provided with a mounting hole, the mounting hole is fixedly provided with an annular platform, the annular platform is sleeved with a first washer, the worm wheel is fixedly connected to the shaft after passing through the mounting hole, and the worm wheel is in contact with the first washer; the worm shaft sleeve is fixedly connected to the worm, a second washer is sleeved at the connection between the worm shaft sleeve and the worm, and the worm shaft sleeve is in contact with the second washer.
[0007] The working principle and beneficial effects of the utility model:
[0008] In this solution, the first washer and the second washer are arranged, the worm wheel is in contact with the first washer, and the worm shaft sleeve is in contact with the second washer. In the process of rotating the worm shaft sleeve to rotate the worm, and in the process of the worm wheel driving the shaft to rotate, the first washer and the second washer produce a damping effect, thereby improving the tuning feel and preventing the entire tuning process from being too loose, thereby effectively controlling the rotation speed of the worm and the worm wheel and improving the tuning effect.
[0009] Optimally, the worm wheel and the shaft rod are fixed by using a slotted countersunk screw.
[0010] The optimization further comprises a handle, wherein the handle and the worm shaft sleeve are connected by a cross countersunk screw, and a third washer is provided at the connection between the handle and the worm shaft sleeve.
[0011] Optimally, the first washer is a stainless steel corrugated washer, and the second washer and the third washer are plastic washers.
[0012] Optimally, the shaft rod is specifically a rubber-coated shaft rod. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is an exploded view of a musical instrument tuning device in an embodiment. DETAILED DESCRIPTION
[0014] The following is further described in detail through specific implementation methods:
[0015] The figure marks in the drawings of the specification include: base plate 1, plastic washer 2, worm 3, shaft 4, stainless steel corrugated washer 5, worm wheel 6, slotted countersunk screw 7, plastic washer 8, handle 9, cross countersunk screw 10, worm shaft sleeve 11, mounting hole 12, annular platform 13.
[0016] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.
[0017] Embodiment: A musical instrument tuning device, such as Figure 1 As shown, it includes a shaft rod 4, a worm wheel 6, a base plate 1, a worm shaft sleeve 11, a worm 3, and a handle 9. The base plate 1 is provided with a mounting hole 12, and a ring platform 13 is fixedly provided in the mounting hole 12.
[0018] Place the stainless steel corrugated washer 5 on the annular platform 13 in the mounting hole 12, insert the worm wheel 6 and the shaft rod 4 into the mounting hole 12, use a slotted countersunk screw 7 to pass through the worm wheel 6 and the shaft rod 4 and tighten them to fix the worm wheel 6 and the shaft rod 4 together, and the annular platform 13 plays a limiting role to prevent the worm wheel 6 and the shaft rod 4 from slipping out of the mounting hole 12.
[0019] The worm wheel 6 contacts and squeezes the stainless steel corrugated washer 5. The plastic washer 2 is sleeved on the worm 3, and the worm 3 is assembled on the base plate 1 (the worm 3 is rotatably connected to the base plate 1), another plastic washer 8 and a worm shaft sleeve 11 are sleeved on the worm 3, and a cross semi-countersunk screw 10 is passed through the handle 9 and tightened on the worm 3, so that the handle 9, the worm shaft sleeve 11 and the worm 3 are fixed.
[0020] In this scheme, by arranging the plastic washer 2 and the stainless steel corrugated washer 5, when the handle 9 is turned and the worm shaft sleeve 11 rotates the worm 3 and when the worm wheel 6 drives the shaft 4 to rotate, the plastic washer 2 and the stainless steel corrugated washer 5 produce a damping effect on the rotation of the worm 3 and the worm wheel 6, thereby improving the tuning feel and preventing the entire tuning process from being too loose, thereby effectively controlling the rotation speed of the worm 3 and the worm wheel 6 and improving the tuning effect.
[0021] Preferably, the worm gear 6 and the mounting hole 12 are coaxially rotatably connected. This arrangement improves the reliability of the entire connection.
[0022] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
