Description

Lawn mower handle with protection

Technical Field

The utility model relates to the technical field of lawn mowers, in particular to a lawn mower handle with a protective function.

Background Art

A lawn mower is also called a weed cutter, a lawn mower, a lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It consists of a moving component, a mowing component, a casing, and a handle.

When mowing the lawn, a household lawn mower may encounter the problem that the mowing blade is stuck by a large amount of weeds and cannot rotate. At this time, the mowing component cannot work properly. To solve this problem, an anti-collision bar and a ground spike are installed at one end of the housing mounting handle. The anti-collision bar is installed between the operator's legs and the lawn mower, and the ground spikes are installed on both sides of the housing. At this time, the operator controls the handle with both hands and steps on the anti-collision bar with his feet. The leg force pushes the anti-collision bar down, so that the end of the lawn mower close to the operator sinks and the other end is lifted up. At this time, the ground spikes are embedded in the grass. The ground spikes are to help the lawn mower keep the lifted state. Lifting one end of the lawn mower can make it easier for the operator to observe the mowing component and remove the weeds without turning over the entire lawn mower.

Although the above method can quickly solve the problem of weeds getting stuck on the blade, the ground spikes cannot support the entire raised lawn mower for a long time. For aesthetics and installation requirements, the ground spikes are generally slender in shape, which makes the supporting force of the ground spikes insufficient. If the operator needs to clean weeds at the bottom of the lawn mower for a long time, the lawn mower may hit the operator, causing safety problems.

As shown in Fig. 1-5, a lawn mower handle with a protective function includes a steering tube 1 and an adjustment tube 2. The steering tube 1 is sleeved on the outside of the adjustment tube 2. The adjustment tube 2 is slidably connected to the steering tube 1. A lifting groove 9 is provided on the top outer wall of the adjustment tube 2. A fitting block 11 is embedded and installed inside the adjustment tube 2. A built-in rod 6 is fixedly installed on the top of the fitting block 11. One end of the built-in rod 6 passes through the lifting groove 9 and extends out of the adjustment tube 2. A sleeve 10 is sleeved and installed on the outside of the built-in rod 6. A support rod 12 is rotatably installed below the fitting block 11. The outer wall of the fitting block 11 is in contact with the inner wall of the adjustment tube 2. One end of the built-in rod 6 extends out of the adjustment tube 2, and the other end is arranged coplanar with the side wall of the fitting block 11. It should be noted that part of the tube body of the adjustment tube 2 can slide in the steering tube 1. It can be understood that the telescopic rod composed of the adjustment tube 2 and the steering tube 1 is installed on the side of the lawn mower and serves as a handle for the operator to push the lawn mower to move. Please refer to Figures 1 and 4. To ensure balance, the telescopic rod composed of the adjustment tube 2 and the steering tube 1 is set in two groups and is set on both sides of the lawn mower. For easy understanding, the lawn mower is replaced by a body 16, which includes a moving component, a mowing component, a ground spike 17 and an anti-collision rod 18. It can be understood that the moving component includes a rotating wheel, which is installed on the side of the body 16 for the body 16 to move on the grass, and the mowing component includes an electric control terminal and a mowing blade. The ground spikes 17 are fixedly installed on the outer wall of the body 16. The installation position of the ground spikes 17 is close to the steering tube 1. To ensure balance, the ground spikes 17 are also arranged in two groups. The tips of the bottoms of the ground spikes 17 face the ground. The anti-collision rods 18 are installed on the outside of the body 16. The ends of the anti-collision rods 18 are fixedly connected to the outer wall of the body 16. When the operator operates the body 16, the anti-collision rods 18 are located between the legs of the operator and the body 16.

Please refer to Figures 4-5. The outer wall of the bottom end of the steering tube 1 is rotatably connected to the side of the body 16. The operator adjusts the angle and length of the telescopic rod according to his or her height and arm span. The steering tube 1 is used to adjust the angle of the telescopic rod, and the adjusting tube 2 is used to adjust the length of the telescopic rod. After the telescopic rod is adjusted, the operator holds the sleeve 10 and pushes the body 16 to mow the grass. When the mowing component of the body 16 fails to work properly, the operator holds the sleeve 10 with both hands and steps on the anti-collision rod 18 with his or her feet. The operator uses his or her legs to step on the anti-collision rod 18 downward, causing the end of the body 16 close to the operator to sink and the other end to lift up. At this time, the ground nail 17 is embedded in the grass. The purpose of lifting one end of the body 16 is to facilitate observation of the mowing component at the bottom of the body 16 for easy maintenance.

Please refer to Figures 1, 4 and 5. A rotation groove is provided at the bottom of the engaging block 11. The top end of the support rod 12 is embedded in the rotation groove. A fixed rod (not shown in the figure) is fixedly installed in the rotation groove. It can be understood that the fixed rod passes through the end of the support rod 12, and the support rod 12 rotates around the fixed rod as the axis. A slot 2 4 is provided on the outer wall of one side of the adjusting tube 2. The slot 2 4 is provided on the rotation path of the support rod 12. A slot 1 3 is provided on the outer wall of one side of the steering tube 1. The slot 1 3 is provided at a position corresponding to the slot 2 4. After the operator adjusts the angle and length of the telescopic rod, the telescopic rod is inclined. The slot 1 3 and the slot 2 4 are both provided on the side of the steering tube 1 and the adjusting tube 2 facing the bottom surface.

Please refer to 1-3. A sliding groove 13 is provided through the outer wall of the built-in rod 6. A sliding rod 15 is provided inside the sliding groove 13. The end of the sliding rod 15 is fixedly connected to the sleeve 10. A spring 14 is embedded inside the sleeve 10. One end of the spring 14 is fixedly connected to the end of the built-in rod 6, and the other end is fixedly connected to the inner wall of the sleeve 10. The spring 14 is arranged in a colinear relationship with the axis of the built-in rod 6. A fixing groove 15 and a fixing groove 28 are provided on the outer wall of the adjusting tube 2 on the side away from the lifting groove 9. The fixing groove 28 is provided above the fixing groove 15. A matching tube 7 is provided on the outer wall of the built-in rod 6 located inside the adjusting tube 2. One end of the matching tube 7 is fixedly connected to the sleeve 10, and the other end passes through the fixing groove 15 and fits with the inner wall of the fixing groove 15. A limiting groove is provided at the connection position between the interlocking block 11 and the built-in rod 6. The function of the limiting groove is to prevent the matching tube 7 from interfering with the interlocking block 11. In the initial state, the matching tube 7 is inserted into the fixing groove 5 , the sleeve 10 is located at the bottom of the lifting groove 9 , and the end of the support rod 12 away from the engaging block 11 is blocked by the inner wall of the adjusting tube 2 .

The operator pulls the sleeve 10 to the side away from the adjusting tube 2, the slide bar 15 slides in the slide groove 13, the spring 14 stretches and deforms, the matching tube 7 is separated from the fixed groove 1 5, and then the operator pulls the sleeve 10 in the direction of the fixed groove 2 8, the sleeve 10 pulls the built-in rod 6, the built-in rod 6 drives the engaging block 11, the engaging block 11 drives the support rod 12 to move, the matching tube 7 is against the top inner wall of the lifting groove 9, and then the operator drives the sleeve 10 to embed the matching tube 7 at the other end of the sleeve 10 into the fixed groove 2 8, so that The operator pulls the support rod 12 forward as a whole for a distance, so that the bottom end of the support rod 12 moves to the position of the slot 2 4 and is not blocked by the adjustment tube 2. At this time, the adjustment tube 2 is in an inclined state. Due to its own gravity, the support rod 12 rotates downward through the slot 2 4 with the fixed rod inside the fitting block 11 as the axis until the end of the support rod 12 contacts the ground. At this time, the operator presses down the sleeve 10 with his hand, and the sleeve 10 drives the entire telescopic rod to flip toward the ground, so that the support rod 12 is embedded deeper into the ground. This is to cooperate with the support rod 12 and the ground nails 17 of the machine body 16. The two groups of support rods 12 and the two groups of ground nails 17 are embedded in the ground, so that the machine body 16 can be more stably kept in the lifted state, which is convenient for the operator to check the mowing components and increase safety.

After the inspection is completed, the operator presses down the raised end of the machine body 16 so that the machine body 16 is again attached to the ground, and the ground nail 17 and the support rod 12 are both off the ground. The operator operates the sleeve 10 to adjust the angle of the adjustment tube 2 and the steering tube 1 so that the entire telescopic rod is perpendicular to the ground. The support rod 12 is always perpendicular to the ground due to its own gravity, so at this time the support rod 12 is recovered into the adjustment tube 2 through the slot 2 4. Then the operator operates the sleeve 10 to move the built-in rod 6 and the embedded block 11 downward so that the matching tube 7 is matched with the fixing slot 1 5 again, and the bottom end of the support rod 12 is blocked by the inner wall of the adjustment tube 2. Then the operator continues to push the machine body 16 to mow the grass.
