Description of the embodiments
Fig. 1, fig. 2 and fig. 3 show that a concrete implementation of a reverse mowing locking mechanism of a lawn mower is created, the lawn mower comprises a frame 3, a clutch lever 1 for controlling a cutter to be separated in power or combined with E, a baffle 5, a gear lever 8 with three-gear operation modes of a forward gear F, a neutral gear N and a reverse gear R, a transmission mechanism and a clutch mechanism, wherein the clutch lever 1, the baffle 5 and the gear lever 8 are respectively hinged on the frame 3, the clutch lever 1 drives the baffle 5 to synchronously rotate through the transmission mechanism, a first chute 9 and a second chute 6 are arranged on the gear lever 8, the clutch mechanism comprises a sliding handle 10, a pressure spring 11, a sliding handle pin 12, a linkage piece 13 and a blocking pin 7, the sliding handle 10 is sleeved on the gear lever 8 and can move up and down relative to the first chute 9 through the sliding handle pin 12, the pressure spring 11 is arranged in the first chute 9, the sliding handle 10 has a reset thrust for downward movement, the blocking pin 7 is arranged on the second chute 6 in a manner, and the linkage piece 13 is connected between the sliding handle pin 12 and the blocking pin 7; a reset tension spring 4 is connected between the baffle 5 and the frame 3. The catch pin 7 cooperates with a radial edge 17 of the shutter 5 when the neutral position N is in engagement with the E-state, and the catch pin 7 cooperates with a circumferential edge 18 of the shutter 5 when the reverse position R is in engagement with the E-state.
In order to facilitate transmission, the transmission mechanism is a flexible shaft, two ends of the flexible shaft are fixed on a frame 3 corresponding to the clutch lever 1 and the baffle plate 5, and the length of a guy cable 2 of the flexible shaft is correspondingly fixed on the clutch lever 1 and the baffle plate 5 in an adjustable manner. For easy installation, the clutch lever 1 and the gear lever 8 are rotatably mounted on the frame 3 by a step screw 16, and the baffle 5 is rotatably mounted on the frame 3 by a shaft sleeve 15 and a pressing plate 14. For ease of use, the radial edge 17 is a smooth planar surface and the circumferential edge 18 is a smooth arcuate surface.
The working process of the invention is as follows: when the clutch lever 1 and the shutter 5 are in the disengaged D position, the gear lever 8 may be unhindered to be engaged into the reverse gear R, as shown in fig. 5. When the clutch lever 1 and the baffle 5 are in the position of combining E, as shown in figure 3, if the reverse gear R is to be engaged, the sliding handle 10, the sliding handle pin 12, the linkage piece 13 and the baffle pin 7 must be moved upwards to engage the reverse gear R, as shown in figure 4; at this time, if the clutch lever 8 returns to the separation D, the shutter 5 also returns to the separation D position under the action of the return tension spring 4, and the slide lever 10, the slide lever pin 12, the link piece 13, and the stopper pin 7 return to the initial position under the action of the self weight and the compression spring 11, as shown in fig. 5; when the clutch lever 1 is operated again to the engaged E position in this state, the shutter 5 forcibly pushes the shift lever 8 to the neutral N position as shown in fig. 3. In the state of mowing in reverse, as shown in fig. 4, if the gear lever 8 is engaged in the neutral gear N, the sliding handle 10, the sliding handle pin 12, the linkage piece 13 and the blocking pin 7 are also reset to the initial positions under the action of the dead weight and the pressure spring 11, as shown in fig. 3; at this time, if the reverse gear R is engaged again, the sliding handle 10, the sliding handle pin 12, the linkage piece 13 and the stop pin 7 still need to be moved upwards again, so that the safety requirement is completely met.
The foregoing is a specific embodiment of the present invention and is not intended to limit the invention in any way, but rather to make simple modifications, equivalent variations or modifications without departing from the technical solution of the invention, all falling within the scope of the invention.
