Technical Field
[0001] The utility model relates to the technical field of guitar manufacturing, in particular to a guitar bass fixed bridge capable of adjusting octaves. Background Art
[0002] The bridge is responsible for transmitting the energy of the string vibration. When the strings vibrate, each string will produce a fundamental frequency (the frequency of the fundamental tone, which determines the pitch of the entire sound) and the overtones produced by each string. The fundamental frequencies and overtones produced by the strings are the input signals, and the bridge collects these signals with the greatest efficiency and transmits them to the panel as completely as possible.
[0003] The existing fixed guitar bridge relies on the compensation of the lower saddle to adjust the octave intonation problem of the guitar, but it is far from enough. If thicker strings are replaced, the octave intonation deviation will be greater and the existing technology cannot solve it. Therefore, the present application provides a fixed guitar and bass bridge with adjustable octave to meet the needs. Utility Model Content

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0033] Example: Reference Figure 1-4 The octave-adjustable fixed bridge for guitar and bass shown in the figure comprises a guitar body 1 and a bridge 2 fixedly connected to the guitar body 1, an adjustment slot 14 is provided in the bridge 2, a lower saddle 13 is provided in the adjustment slot 14, and an adjustment structure for adjusting the position of the lower saddle 13 is also provided in the bridge 2;
[0034] The spacing of the adjustment slots 14 is greater than the width of the lower saddle 13:
[0035] The adjustment structure can push the lower saddle 13 to slide back and forth in the adjustment slot 14.
[0036] During use, the user can install the lower saddle 13 in the adjustment slot 14 in the bridge 2, and can use the adjustment structure to adjust the lower saddle 13 according to usage requirements, so that the lower saddle 13 slides back and forth in the adjustment slot 14, so as to adapt to the user's usage habits and compensation for octaves.
[0037] By setting up an adjustment structure, the adjustment slot 14 for installing the lower saddle 13 in the bridge 2 is widened by several millimeters, thereby increasing the activity space of the lower saddle 13 inside the fixed bridge 2. The adjustment structure can be used to push the lower saddle 13 to move and adjust, so that the lower saddle 13 can be freely moved back and forth inside the bridge instead of being unable to move, and the octave cannot be adjusted to be able to adjust and compensate for the octave accuracy, thereby solving the problem that the octave accuracy of the fixed guitar bridge cannot be adjusted.
[0038] like Figure 4 As shown, the adjustment structure includes four second screw grooves 5 symmetrically arranged at the front and rear of the bridge 2;
[0039] And the four second screw grooves 5 are all connected to the adjustment groove 14;
[0040] The first screw rods 6 are rotatably connected to the two symmetrical second screw grooves 5, and the second screw rods 11 are threadedly connected to the other two symmetrical second screw grooves 5, and the first screw rods 10 and the second screw rods 12 are fixedly connected to the first screw rods 6 and the second screw rods 11, respectively;
[0041] The first screw thread 10 is located in the adjusting groove 14 and matched with the lower saddle 13 , and the second screw thread 12 is threadedly matched with the bridge 2 .
[0042] The first screw rod 6 and the second screw rod 11 are respectively installed in two symmetrical second screw grooves 5, and the screw head of the first screw rod 6 is an inner cavity hexagonal groove structure, which can be adjusted with a hexagonal wrench when in use. The hexagonal wrench is inserted into the hexagonal groove of the first screw rod 6 or the second screw rod 11, thereby driving the first screw rod 6 or the second screw rod 11 to rotate, so that the second screw rod 11 is threadedly connected to the bridge 2 through the second screw strip 12 for fixing.
[0043] The opening of the second screw groove 5 provides installation space for the first screw rod 6 and the second screw rod 11, making their installation and docking simple. The design of the second screw strip 12 ensures that the second screw rod 11 is fixed on the bridge 2 after installation. The first screw strip 10 is set in the adjustment groove 14 so that the first screw rod 6 can continue to rotate and cooperate with the lower saddle 13 after installation.
[0044] like Figure 4 As shown, the first screw rod 6 and the second screw rod 11 both pass through the lower saddle 13;
[0045] The lower nut 13 is threadably engaged with the first screw rod 6 and is slidingly engaged with the second screw rod 11 .
[0046] In summary, when the first screw rod 6 is driven to rotate by the hexagonal wrench, it will cooperate with the thread of the lower nut 13, so that the lower nut 13 is pushed to slide forward and backward along the second screw rod 11 through the forward and reverse rotation of the hexagonal wrench.
[0047] The second screw 11 is provided to provide a guiding effect for the lower nut 13, so that it can only slide along the second screw 11 during the threaded engagement with the first screw 6, thereby avoiding the situation where the lower nut 13 also rotates during the threaded engagement, and the distance can be more accurately grasped by means of threaded adjustment.
[0048] like Figure 4 As shown, a rotating sleeve 7 is rotatably disposed in one of the second screw grooves 5, and one end of the first screw rod 6 is threadedly connected to the rotating sleeve 7;
[0049] The rotating sleeve 7 is rotatably arranged in the second screw groove 5 via the rotating shaft 9;
[0050] The rotating sleeve 7 is also fixedly connected with a friction plate 8 for increasing friction;
[0051] Furthermore, chamfered grooves are provided on the corner edges of the bridge 2 .
[0052] In summary, press the friction plate 8, and then screw the first screw 6 into the second screw groove 5. The first screw 6 will be threadedly connected to the rotating sleeve 7, and then the installation of the first screw 6 will be completed. When the first screw 6 is rotated, the first screw 6 will rotate and drive the rotating sleeve 7 to rotate on the rotating shaft 9. When disassembling, continue to resist the friction plate 8, limit the rotating sleeve 7 by the friction force of the hand, and then rotate the first screw 6 in the opposite direction to remove the first screw 6, and the second screw 11 can be disassembled to replace the lower nut 13.
[0053] The rotating sleeve 7 is arranged so that the first screw rod 6 can be rotated in place after the installation is completed. When the first screw rod 6 rotates, it can cooperate by its own synchronous rotation, so that the first screw rod 6 itself will not move forward and backward when it rotates, so that it can cooperate with the lower nut 13 thread after the installation is completed, and the use is more stable. The friction plate 8 arranged can limit the rotating sleeve 7 through simple resistance, making it easy to use and easy to disassemble.
[0054] like Figure 3 and 4 As shown, the bridge 2 is fixedly connected to the guitar body 1 by machine screws 3;
[0055] First screw grooves 4 are provided on both sides of the top of the bridge 2 , and the machine screws 3 are matched with the first screw grooves 4 .
[0056] When in use, the machine screw 3 is screwed into the first screw groove 4 to install the bridge 2 on the guitar body 1, and the top opening of the first screw groove 4 is larger. After the machine screw 3 is completely screwed into the first screw groove 4, the screw head of the machine screw 3 will enter the larger opening.
[0057] By designing the first screw groove 4 to have an enlarged opening, the machine screw 3 can be completely screwed into the bridge 2 so that it does not protrude from the surface of the bridge 2 and does not affect the overall appearance.
[0058] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
