DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0030] A gearbox shift housing, comprising:

[0031] Gear shift protection case 1;

[0032] A movable groove 2, which is disposed at the upper end of the gear shift protection housing 1;

[0033] A moving plate 3, the moving plate 3 is slidably connected in the moving groove 2;

[0034] The fixing components include a fixing groove 4, a fixing cylinder 5, an insertion rod 6, an insertion block 7, an embedding groove 8, an insertion thread 9 and a fixing thread 10. There are multiple fixing grooves 4, embedding grooves 8 and fixing threads 10. Multiple fixing grooves 4 are all opened on the upper inner wall of the movable groove 2. Multiple fixing threads 10 are respectively opened in multiple fixing grooves 4. Multiple embedding grooves 8 are all opened at the upper end of the movable plate 3. The fixing cylinder 5 is fixedly connected to the upper end of the embedding groove 8. The insertion rod 6 is slidably connected in the insertion rod 6. The insertion block 7 is fixedly connected to the lower end of the insertion rod 6 and slides in multiple fixing grooves 4 and the embedding groove 8. The insertion thread 9 is opened on the circumferential surface of the insertion block 7 and is threadedly connected with multiple fixing threads 10.

[0035] When the shifting groove is needed to adjust the position of the shifting groove, the insertion rod 6 is pulled upward to pull the insertion block 7 out of the fixed groove 4. At this time, the insertion block 7 is inserted into the embedding groove 8, which will not restrict the sliding of the moving plate 3. Then, the moving plate 3 is slid to the specified position, and then the insertion block 7 is inserted into the newly aligned fixed groove 4. Then, the insertion rod 6 is rotated to make the insertion thread 9 and the fixing thread 10 threadedly connected, thereby completing the fixation between the shifting protection shell 1 and the moving plate 3, and then fixing the position of the shifting groove opened on the upper end of the moving plate 3, thereby completing the position adjustment of the shifting groove, so that the device can be installed in different shifting positions by adjusting the position of the moving groove 2 to complete the installation of different control shafts.

[0036] For details, please refer to Figure 1-Figure 5 A rotating plate 11 is fixedly connected to the circumferential surface of the insertion rod 6 , and a return spring 12 is provided on the lower side of the rotating plate 11 .

[0037] In this embodiment: the return spring 12 is fixed to the lower inner wall of the fixed cylinder 5, and the upper end is in contact with the rotating plate 11 but not fixed to the rotating plate 11. When the insertion block 7 is inserted into the fixed groove 4, the rotating plate 11 slides downward in the fixed cylinder 5 to squeeze the return spring 12 to shrink. When the insertion thread 9 and the fixed thread 10 are threadedly fixed, the return spring 12 is always in a contracted state until the movable groove 2 changes its position again, the insertion thread 9 is turned out of the fixed thread 10, and the previously squeezed and shrunk return spring 12 rebounds, pushing the insertion block 7 out of the fixed groove 4, and then the insertion rod 6 can be pulled to change the position of the movable groove 2.

[0038] For details, please refer to Figure 1-Figure 5 The upper end of the insertion rod 6 is fixedly connected with a twisting block 13.

[0039] In this embodiment, the twisting block 13 is fixed to the upper end of the insertion rod 6 and is pentagonal, which is convenient for the rotation of the insertion block 7 after it is inserted into the fixed groove 4, and after the insertion block 7 is pulled out, the twisting block 13 is pulled to drive the movable groove 2 to move.

[0040] For details, please refer to Figure 1-Figure 5 A scale 14 is provided at the upper end of the gear shift protection housing 1 .

[0041] In this embodiment, a scale 14 is disposed at the upper end of the moving groove 2 to mark the fixed distance of the moving groove 2 . The scale 14 facilitates the operator to control the moving distance of the moving groove 2 .

[0042] For details, please refer to Figure 1-Figure 5 A plurality of rotating shaft grooves 15 are formed at the side end of the gear shift protection housing 1 .

[0043] In this embodiment, a plurality of rotating shaft grooves 15 are provided on the surface of the gear shift protection housing 1 , so that the device can protect control rods at different positions.

[0044] For details, please refer to Figure 1-Figure 5 The gear shift protection shell 1 is an upper and lower combined shell.

[0045] In this embodiment: the gear shift protection shell 1 is a protection shell body installed by threads and bolts at the top and bottom, and a sealing ring is provided at the connection to ensure the sealing performance inside the gear shift protection shell 1.

[0046] When the gear shifting groove 2 is in the fixed position, the insertion block 7 is pulled out of the fixed groove 4 by pulling the insertion rod 6 upward. At this time, the insertion block 7 is inserted into the embedded groove 8, which will not restrict the sliding of the moving plate 3. Then the moving plate 3 is slid to the specified position, and then the insertion block 7 is inserted into the newly aligned fixed groove 4. Then the insertion rod 6 is rotated to make the insertion thread 9 and the fixing thread 10 threadedly connected, thereby completing the fixation between the gear shifting protection shell 1 and the moving plate 3, and then fixing the position of the gear shifting groove opened on the upper end of the moving plate 3, thereby completing the position adjustment of the gear shifting groove, so that the device can be installed in different shifting positions, and the installation of different control shafts can be ensured by adjusting the position of the moving groove 2.
