Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-5, a shoulder-mounted weeder connecting mechanism is consistent with a traditional shoulder-mounted weeder structure, and comprises a support tube 4 for a user to hold, wherein one axial end of the support tube 4 is provided with a power source, the other axial end of the support tube 4 is provided with a mounting piece 1, a driving motor is fixed in the mounting piece 1, and the lower end of the driving motor is fixedly connected with a cutting rope or a cutting blade to form a cutting mechanism.
It should be emphasized that the device is mainly used for connection between the support tube 4 and the mounting member 1, and aims to quickly connect the mounting member 1 and the support tube 4, avoid the existence of auxiliary screws and reduce the possibility of screw loss.
Specifically, a sleeve 3 is sleeved outside the support tube 4, the sleeve 3 is in sliding connection with the support tube 4, and the sleeve 3 moves linearly along the central axis of the support tube 4.
The other axial end in the sleeve 3 is inserted with a mounting tube 2.
The rotation groove 10 has been seted up to installation tube 2 lateral wall, has peg graft stopper 11 in the rotation groove 10, thereby stopper 11 and sleeve pipe 3 inner wall fixed connection make when stopper 11 are located rotation groove 10, installation tube 2 only can rotate for sleeve pipe 3.
The chute I9 is arranged on the inner side wall of the positioning tube 6.
A positioning tube 6 is inserted in the mounting tube 2, and the other axial end of the positioning tube 6 is fixedly connected with the mounting piece 1.
The locating tube 6 is kept away from mounting 1 one end fixedly connected with slider I7, thereby slider I7 peg graft in spout I9 so that locating tube 6 can slide for mounting tube 2.
Every spout I9 both ends are not in same vertical plane and spout I9 inner wall smooth transition, promptly when guaranteeing that locating tube 6 does not take place to rotate, when pegging graft locating tube 6 in spout I9, slider I7 will with spout I9 cooperation force installation tube 2 to take place to rotate for sleeve pipe 3, stopper 11 is located the rotation inslot 10 this moment.
In practice, the user can hold installed part 1 and retrain installed part 1, peg graft positioning tube 6 in installed pipe 2, and in this moment, retraining slider I7 gets into spout I9, and slider I7 and spout I9 cooperation force installed pipe 2 to rotate this moment. Similarly, when the slider i 7 enters the mounting tube 2 and is far away from one end of the mounting member 1, if the mounting tube 2 is limited to rotate, the slider i 7 cannot slide in the sliding groove i 9 due to the gravity influence of the component arranged at the lower end of the mounting member 1, and at this time, if the slider i 7 wants to slide in the sliding groove i 9, the mounting member 1 needs to be integrally turned.
The mounting tube 2 lateral wall has still offered spacing groove 8, spacing groove 8 and rotary groove 10 logical joint, at this moment, constraint spacing groove 8 position for when slider I7 is located spout I9 and keeps away from mounting 1 one end, every stopper 11 is in same vertical face with corresponding spacing groove 8, promptly when locating tube 6 pegging graft completely and get into mounting tube 2 and make slider I7 be located spout I9 and keep away from mounting 1 one end, user slidable sleeve 3 makes stopper 11 sink into spacing groove 8, can restrain mounting tube 2 and can not take place the rotation when stopper 11 is submerged into spacing groove 8.
Furthermore, the outer end surface of the supporting tube 4 is fixedly connected with a limiting ring 14, one end of the limiting ring 14 close to the mounting piece 1 is coaxially and fixedly connected with a compression spring 5, and the other axial end of the compression spring 5 is fixedly connected with the sleeve 3, so that the sleeve 3 has a trend of moving towards the mounting piece 1 by utilizing the compression spring 5, and when the limiting block 11 and the limiting groove 8 are located in the same vertical plane, the compression spring 5 can force the limiting block 11 to enter the limiting groove 8.
Simultaneously, compression spring 5 exists also to make stopper 11 can with installation pipe 2 butt, and this lifts can retrain installation pipe 2, makes it restricted at free rotation in-process, and this action can be convenient for the user to adjust spout I9 position for installation piece 1 grafting position is suitable.
And, sleeve pipe 3 inside wall fixedly connected with damping ring cover 15, thereby further adjust installation tube 2 rotation in-process atress, guarantee the grafting convenience between damping ring cover 15 and the installation tube 2.
Specifically, stay tube 4 is close to a plurality of sliders II 13 of mounting 1 one end outside terminal surface circumference fixedly connected with, and a plurality of spouts II 12 have been seted up to slider II 13 to the inboard terminal surface of sleeve pipe 3, and slider II 13 is pegged graft inside spout II 12 to utilize slider II 13 and spout II 12 to retrain sleeve pipe 3, avoid sleeve pipe 3 to follow mounting tube 2 and take place to rotate, guarantee along with mounting tube 2 rotates, stopper 11 can be in same horizontal plane with spacing groove 8.
Meanwhile, two ends of each sliding groove do not penetrate through the sleeve 3, the position of the sleeve 3 can be restrained by combining the shape structure of the sleeve 3, and the reliability of connection between the sleeve 3 and the supporting tube 4 is guaranteed.
The utility model is in the actual use process:
Firstly, a user holds the mounting piece 1 by hand to insert the positioning tube 6 into the mounting tube 2, at the moment, the sliding block I7 enters the sliding groove I9, at the moment, the mounting tube 2 rotates relative to the positioning tube 6 and the sleeve 3 along with the gradual penetration of the positioning tube 6 into the mounting tube 2
After that, when slider I7 is located spout I9 and keeps away from mounting 1 one end, stopper 11 and spacing groove 8 are in same vertical face, and at this moment, under compression spring 5 effect, stopper 11 submerges in spacing groove 8, and at this moment, installation pipe 2 can not take place to rotate.
Finally, when the user needs to separate the positioning tube 6 from the mounting tube 2, the sleeve 3 is pulled upwards, at this time, the limiting block 11 is located in the rotating groove 10, at this time, the limiting block is constrained by the damping ring sleeve 15, the sliding block I7 corresponds to the sliding groove in position, and the user pulls the mounting piece 1 to pull the positioning tube 6 out of the mounting tube 2.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
