[0027] Example
[0028] like Figures 1 to 3 As shown, the double-tube sleeve type handwheel locking device proposed in this utility model includes: two sets of turbine boxes 1, and the turbine box 1 is the prior art, so it will not be described in detail here. A mounting plate 15 is fixedly provided on one side of the turbine box 1, which can stably install the turbine box 1 with bolts. A handwheel 2 is fixedly provided on one side of the turbine box 1, which facilitates the transmission of the turbine box 1 by the handwheel 2.
[0029] Furthermore, the turbine rod 3, which runs through the turbine housing 1, can drive the turbine rod 3 to move. One end of the turbine rod 3 is fixedly connected to a connecting block 4. Both sides of the connecting block 4 are respectively hinged to linkage rods 5, which can simultaneously drive the linkage rods 5 on both sides to move. One end of the linkage rod 5 is hinged to a linkage piece 6. One end of the linkage piece 6 is rotatably provided with a mounting base 16, which facilitates the stable installation of the linkage piece 6 and limits the movement of the linkage piece 6. One end of the linkage piece 6 is hinged to a locking rod 7, and one end of the locking rod 7 is hinged to a locking plug 8, which can make them move simultaneously, thereby achieving rapid locking.
[0030] Secondly, an inner sleeve rod 9 and an outer sleeve rod 10 are provided between the handwheels 2. The inner sleeve rod 9 and the outer sleeve rod 10 are movably connected and their lengths can be adjusted according to the distance between the handwheels 2. Fixed blocks 11 are fixedly provided at opposite ends of the inner sleeve rod 9 and the outer sleeve rod 10. A set of fixed posts 12 are fixedly provided on one side of the fixed blocks 11, and the fixed posts 12 are symmetrically arranged. The outer walls of the fixed posts 12 are rotatably fitted with locking blocks 13. The locking blocks 13 are triangular in structure, which can stably lock the locking blocks 13 with the handwheels 2.
[0031] like Figures 2 to 4As shown, a positioning component 14 is disposed between the inner sleeve rod 9 and the outer sleeve rod 10 to limit the position of the locking block 13. A protective cover is fitted onto the outer wall of the positioning component 14. The protective cover can be locked with a padlock to prevent unauthorized operation. The positioning component 14 includes a fixing sleeve 141 fixedly fitted onto the outer wall of the inner sleeve rod 9. A set of guide rods 142 is fixedly disposed on one side of the fixing sleeve 141. One side of the guide rods 142 is provided with anti-slip texture. A sleeve block 143 is movably fitted between the guide rods 142. The sleeve block 143 and... One end of the outer sleeve rod 10 is fixedly connected, which can limit the inner sleeve rod 9 and the outer sleeve rod 10 to ensure the stability of their displacement. Two guide grooves 144 are opened on the upper part of the sleeve block 143. Pressure plates 145 are slidably arranged inside the guide grooves 144 to ensure the stability of the movement of the pressure plates 145. Anti-slip texture is provided on one side of the pressure plate 145. The pressure plate 145 is located on one side of the guide rod 142 and can be in close contact with the anti-slip texture on the guide rod 142, thereby increasing the contact friction and stably limiting the inner sleeve rod 9 and the outer sleeve rod 10.
[0032] Furthermore, a connecting rod 146 is fixedly installed on one side of the pressure plate 145. The connecting rod 146 has an "L" shaped structure. The connecting rod 146 movably passes through the fixed sleeve 141 and extends to connect with a guide rod 147, which facilitates a stable connection with the guide rod 147. The guide rod 147 movably passes through the fixed sleeve 141 and extends to connect with a pressing block 148, which facilitates the simultaneous movement of the pressure plate 145. A spring 149 is sleeved on the outer wall of the connecting rod 146. One end of the spring 149 is fixedly connected to the fixed sleeve 141, and the other end of the spring 149 is fixedly connected to the pressure plate 145. Through the elastic force of the spring 149, the pressure plate 145 and the guide rod 142 are tightly fitted together, improving the stability of the limit.
[0033] The working principle of this embodiment is as follows: When the handwheel 2 is locked, the pressing block 148 is pushed, which drives the guide rod 147 and the connecting rod 146 to move, compressing the spring 149. The connecting rod 146 pushes the pressure plate 145 to slide in the guide groove 144 and move in the opposite direction to the guide rod 142, so that the pressure plate 145 is away from the guide rod 142. Then, the inner sleeve rod 9 is pulled to slide inside the outer sleeve rod 10, so that the inner sleeve rod 9 and the outer sleeve rod 10 drive the locking block 13 to engage with each other on the handwheel 2.
[0034] When the locking block 13 is stably engaged with the handwheel 2, releasing the pressing block 148 provides thrust through the compressed spring 149, pushing the moving pressure plate 145 until it is tightly pressed against the guide rod 142. Because the contact surface between the guide rod 142 and the pressure plate 145 has anti-slip texture, friction is increased. The pressure plate 145 firmly presses against the guide rod 142, thereby stably limiting the locking block 13 and preventing changes in the locking state due to accidental rotation of the handwheel.
[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
