Description

Technical Field

[0001] This utility model relates to the field of clutch technology, specifically a lawnmower clutch that is easy to assemble. Background Technology

[0002] A lawnmower clutch is a device used on lawnmowers to transmit engine power to the cutting shaft in a switching manner. With the advancement of technology, people's requirements for lawnmower clutches are also getting higher and higher.

[0003] Publication number CN209861648U discloses a lawnmower clutch. By using a first and second permanent magnet block, the clutch can be more easily engaged and disengaged. A limiting anti-disengagement mechanism prevents the clutch spring hooks from detaching during prolonged disengagement. A shock-absorbing buffer ring provides shock absorption for the connecting rod, which is beneficial to the clutch's operation. However, this patent still has the following problems in practical use:

[0004] By using permanent magnet blocks No. 1 and No. 2, the clutch can engage and close more easily. The limit switch and anti-disengagement mechanism prevents the clutch spring hooks from detaching after prolonged disengagement. The shock-absorbing buffer ring provides shock absorption for the connecting rod, which is beneficial for clutch operation. However, clutches are typically installed using bolts, and shims are usually placed on the bolts to distribute the tightening force more evenly and improve connection stability. Currently, although shims are simply placed on the bolts, the diameter of the hole in the shim is generally larger than the bolt diameter. This can cause slight misalignment of the shim when the bolt is tightened, making it difficult to ensure even distribution of the tightening force. This can lead to uneven stress on the shim and potential damage.

[0005] A lawnmower clutch that is easy to assemble is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a lawnmower clutch that is easy to assemble, in order to solve the problems mentioned in the background art. Currently, the clutch uses a first and second permanent magnet block to make it easier to engage and disengage. The limit anti-disengagement mechanism prevents the clutch spring hooks from falling off after prolonged disengagement. The shock-absorbing buffer ring provides shock absorption for the connecting rod, which is beneficial to the clutch's operation. However, the clutch is usually installed with bolts. When using bolts, shims need to be placed on the bolts to distribute the bolt force more evenly and improve connection stability. However, currently, although the shims are simply placed directly on the bolts, the diameter of the hole in the shim is generally larger than the bolt diameter. This can cause slight misalignment of the shims when the bolts are tightened, making it impossible to ensure that the shims can evenly bear the bolt force, leading to uneven stress and potential damage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lawnmower clutch that is easy to assemble, comprising a body, a gasket and a bolt, wherein the surface of the body is provided with a plurality of connecting grooves;

[0008] The connecting groove has a connecting hole inside, and a limit anti-disengagement buckle is slidably connected inside the connecting groove. Fixing blocks are symmetrically installed on both sides of the top surface of the limit anti-disengagement buckle. The bottom surface of the fixing block is in close contact with the body. A screw hole is opened in the middle of the fixing block. A clutch spring is engaged inside the connecting hole. Mounting holes are symmetrically opened on both sides of the body. A gasket groove is opened on the outside of the mounting hole.

[0009] Also includes:

[0010] Several grooves are provided below the gasket groove;

[0011] A connecting sleeve is fixedly installed inside the groove;

[0012] The connecting sleeve has a stabilizing block fixedly installed inside.

[0013] Preferably, a return spring is fixedly connected to the middle of the top surface of the stabilizing block, and a limit rod is fixedly connected to the top surface of the return spring.

[0014] Preferably, the limiting rod is connected through the connecting sleeve.

[0015] Preferably, a friction pad is fixedly installed on the bottom surface of the limiting anti-disengagement buckle.

[0016] Preferably, the gasket has symmetrical holes on both sides of its surface, and the holes are connected to the limiting rod through the gasket.

[0017] Preferably, the connecting hole is connected to the bolt through.

[0018] Preferably, the screw hole is connected to the bolt through.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-assemble lawnmower clutch, through the cooperation of the connecting sleeve, stabilizing block, return spring and limiting rod, can limit the position of the shim, thereby reducing the occurrence of slight displacement of the shim when the bolt is tightened onto the device, thus ensuring that the shim can evenly bear the tightening force of the bolt. The specific details are as follows:

[0020] 1. By setting a connecting sleeve, a stabilizing block, a return spring, and a limiting rod, before installing the main body on the device, the hole on the gasket is aligned with the limiting rod, allowing the limiting rod to pass through the hole on the gasket. The gasket can then be placed inside the gasket groove. The bolt is then passed through the mounting hole, aligning the main body and bolt in the installation position. By rotating the bolt, the main body is installed on the device through the action of the bolt. Simultaneously, as the bolt continues to rotate and descend, the bottom of the bolt presses against the top rod, which in turn presses against the return spring, causing the return spring to deform. After the bolt rotates to a certain position, the top rod is positioned inside the hole, and the bolt presses the gasket against the device. This reduces the occurrence of slight gasket misalignment, ensuring that the gasket can evenly bear the bolt's tightening force, resulting in a tighter fit between the bolt and the device.

[0021] 2. By setting up a limit anti-disengagement buckle, a fixing block, screw holes, and friction pads, the limit anti-disengagement buckle is placed inside the connecting groove, and the bottom of the fixing block is fitted with the surface of the body. The bolt is then threaded into the screw hole. After the bolt is threaded into the screw hole, rotating the bolt causes it to descend. Once the bolt reaches a certain position, it is threaded into the screw hole on the body, allowing the limit anti-disengagement buckle to be installed on the body. Simultaneously, a friction pad made of rubber is provided at the bottom of the limit anti-disengagement buckle. This friction pad can compress both sides of the clutch spring without causing damage to the surface of the clutch spring due to excessive compression. Furthermore, the cooperation between the limit anti-disengagement buckle, fixing block, screw holes, and friction pads prevents the hooks at both ends of the clutch spring from detaching during prolonged disengagement.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a lawnmower clutch that is easy to assemble, comprising a body 1, a gasket 11, and bolts 13. The surface of the body 1 has several connecting grooves 2; the interior of each connecting groove 2 has a connecting hole 3; a limit anti-disengagement buckle 4 is slidably connected inside the connecting groove 2; fixing blocks 5 are symmetrically installed on both sides of the top surface of the limit anti-disengagement buckle 4; the bottom surface of the fixing blocks 5 is fitted and connected to the body 1; a screw hole 6 is opened in the center of the fixing block 5; a clutch spring 7 is engaged inside the connecting hole 3; mounting holes 8 are symmetrically opened on both sides of the body 1; a gasket groove 9 is opened outside the mounting hole 8; it also includes: several grooves 14 below the gasket groove 9; a connecting sleeve 15 is fixedly installed inside the groove 14; and a stabilizing block 16 is fixedly installed inside the connecting sleeve 15, such as... Figure 1-6As shown, by setting the connection sleeve 15, the stabilizing block 16, the return spring 17 and the limiting rod 18, the shim 11 can be limited, thereby reducing the occurrence of slight displacement of the shim 11 when the bolt 13 is tightened onto the device, thus ensuring that the shim 11 can evenly bear the tightening force of the bolt 13. At the same time, the body 1 and the clutch spring 7 are both part of the clutch in the prior art and have the same working principle as the prior art, so they will not be described in detail in this article.

[0031] A return spring 17 is fixedly connected to the middle of the top surface of the stabilizing block 16. A limit rod 18 is fixedly connected to the top surface of the return spring 17. The limit rod 18 is connected through the connecting sleeve 15. Figure 4-6 As shown, by setting the connecting sleeve 15, the stabilizing block 16, the return spring 17, and the limiting rod 18, before installing the body 1 onto the device, the hole 12 on the gasket 11 is aligned with the limiting rod 18, so that the limiting rod 18 passes through the hole 12 on the gasket 11. Then the gasket 11 can be placed inside the gasket groove 9. At this time, by passing the bolt 13 through the mounting hole 8, the body 1 and the bolt 13 are aligned at the installation position. By rotating the bolt 13, the body 1 is installed onto the device by the action of the bolt 13. At the same time, as the bolt 13 continues to rotate and descend... This causes the bottom of bolt 13 to press against the push rod, which in turn presses against the return spring 17, causing the return spring 17 to deform. After bolt 13 rotates to a certain position, the push rod is positioned inside the hole 12. At this point, bolt 13 presses the washer 11 against the device, reducing the occurrence of slight misalignment of washer 11. This ensures that washer 11 can evenly bear the tightening force of bolt 13, making the fit between bolt 13 and device tighter. The thickness and material of washer 11 can be selected according to actual conditions.

[0032] A friction pad 10 is fixedly installed on the bottom surface of the limit anti-disengagement buckle 4. Holes 12 are symmetrically opened on both sides of the pad 11, and the holes 12 are connected to the limit rod 18. A connecting hole 3 is connected to a bolt 13, and a screw hole 6 is connected to the bolt 13. Figure 2 , 3As shown, by setting a limit anti-disengagement buckle 4, a fixing block 5, a screw hole 6, and a friction pad 10, the limit anti-disengagement buckle 4 is placed inside the connecting groove 2, so that the bottom of the fixing block 5 fits against the surface of the body 1. The bolt 13 is then threadedly connected to the screw hole 6. After the bolt 13 is threadedly connected to the screw hole 6, the bolt 13 is rotated, causing it to descend. Once the bolt 13 has descended to a certain position, it is threadedly connected to the screw hole 6 on the body 1, thus allowing the limit anti-disengagement buckle 4 to be installed on the body 1. At the same time, a friction pad 10 is provided at the bottom of the limit anti-disengagement buckle 4. The friction pad 10 is made of rubber, which allows the friction pad 10 to squeeze both sides of the clutch spring 7 without causing damage to the surface of the clutch spring 7 due to excessive compression. Furthermore, the cooperation between the limit anti-disengagement buckle 4, the fixing block 5, the screw hole 6, and the friction pad 10 can prevent the hooks at both ends of the clutch spring 7 from falling off during prolonged disengagement.

[0033] Working principle: Before using this easy-to-assemble lawnmower clutch, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6 As shown, firstly, by setting the connecting sleeve 15, the stabilizing block 16, the return spring 17, and the limiting rod 18, before installing the body 1 onto the device, the hole 12 on the gasket 11 is aligned with the limiting rod 18, so that the limiting rod 18 passes through the hole 12 on the gasket 11. Then, the gasket 11 can be placed inside the gasket groove 9. At this time, by passing the bolt 13 through the mounting hole 8, the body 1 and the bolt 13 are aligned in the mounting position. By rotating the bolt 13, the body 1 is installed onto the device by the action of the bolt 13. Meanwhile, as the bolt 13 continues to rotate and descend, the bottom of the bolt 13 will press against the push rod, which in turn will press against the return spring 17, causing the return spring 17 to deform. After the bolt 13 rotates to a certain position, the push rod is located inside the hole 12. At this time, the bolt 13 just presses the washer 11 onto the device, thereby reducing the occurrence of slight displacement of the washer 11 and ensuring that the washer 11 can evenly bear the tightening force of the bolt 13, making the fit between the bolt 13 and the device tighter.

[0034] Secondly, by setting up a limit anti-disengagement buckle 4, a fixing block 5, a screw hole 6, and a friction pad 10, the limit anti-disengagement buckle 4 is placed inside the connecting groove 2, so that the bottom of the fixing block 5 fits against the surface of the body 1. Then, the bolt 13 is threadedly connected to the screw hole 6. After the bolt 13 is threadedly connected to the screw hole 6, the bolt 13 is rotated to lower it. After the bolt 13 is lowered to a certain position, it is threadedly connected to the screw hole 6 on the body 1, so that the limit anti-disengagement buckle 4 can be installed on the body 1. At the same time, the bottom of the limit anti-disengagement buckle 4 is provided with a friction pad 10. The friction pad 10 is made of rubber, which allows the friction pad 10 to squeeze both sides of the clutch spring 7 without causing damage to the surface of the clutch spring 7 due to excessive compression. At the same time, the cooperation between the limit anti-disengagement buckle 4, the fixing block 5, the screw hole 6, and the friction pad 10 can prevent the hooks at both ends of the clutch spring 7 from falling off during long-term disengagement.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
