It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

Example 1

As shown in fig. 1-2, the present embodiment relates to a connecting rod structure of a garden tool, which comprises a front rod 1, a middle rod 2, a rear rod 3 and two pipe joints 4, wherein the lower ends of the front rod and the middle rod are provided with a reducing; the upper end part of the middle rod and the upper end part of the rear rod are provided with assembling external threads, the inner wall of the pipe joint 4 is provided with internal threads 41, the front rod 1, the middle rod 2 and the rear rod 3 are sequentially spliced, the necking at the lower end part of the front rod 1 is embedded into the upper end part of the middle rod 2, and the necking at the lower end part of the middle rod 2 is embedded into the upper end part of the rear rod 3; the joint 4 of the front rod 1 and the middle rod 2 and the joint of the middle rod 2 and the rear rod 3 are sleeved, and the internal thread 42 is matched with the assembling external thread 6. This connecting rod can be suitable for various garden instrument, and the user of being convenient for freely assembles, and the split is preserved when not using and has also reduced the space and occupy. This connecting rod structure is not only limited to preceding pole and back pole, can make up the extension by oneself according to the demand.

As a preferable embodiment, the outer diameter D1 of the upper side of the pipe joint 4 of the present embodiment is smaller than the outer diameter D2 of the lower side, as shown in fig. 1, that is, the pipe joint adopts a frustum-shaped design, and compared with a cylindrical structure, the slip probability is reduced when the pipe joint is rotatably assembled when held by a palm, and the holding is more stable.

As a preferred embodiment, since the pipe joint 4 is a small-sized component requiring a rotational fitting to each rod, in order to prevent slipping of fingers at the time of manual fitting and to increase surface friction force at the time of holding the pipe joint, anti-slip threads 42 are provided on the outer circumference of the middle and lower sides of the pipe joint. The anti-slip threads 42 are preferably strip-shaped protrusions arranged along the axial direction of the pipe joint.

In a preferred embodiment, the necking 5 is provided with an auxiliary external thread 7, and the auxiliary external thread 7 is in abutting contact with the inner wall of the upper end part of the middle rod or the upper end part of the rear rod. The contact firmness of the necking and the inner wall of the rod is increased.

Preferably, the necking 5 is a two-step stepped structure with a narrow outer section and a wide inner section (the diameter of the outer section is smaller than that of the inner section), and the auxiliary external thread 7 is positioned on the outer section with a small diameter in the stepped structure, as shown in fig. 1.

The pole of this embodiment is cup jointed on the contact, and not only the connector on the limit pole periphery is connected fixedly, still utilizes the second screw thread of throat and throat to carry out the fixed of pole inner wall, and dual fixed connects more firmly, and connection position stability is better.

Example 2

Different from the embodiment 1, in order to further enhance the assembly firmness among the rods and avoid the separation and falling of the rods in the use process after the assembly, a first convex ring 8 is arranged at the lower end part of the front rod or the middle rod, which is close to the necking 5; a first groove 43 is formed in the upper side of the inner wall of the pipe joint, and the first convex ring 8 is matched with the first groove 43; the upper end of the middle rod or the rear rod is provided with a second convex ring 9, the lower side of the inner wall of the pipe joint 4 is provided with a second groove 44, and the second convex ring 9 is matched with the second groove 44. The first convex ring and the second convex ring avoid the separation risk possibly existing in the loosening of the threads in the use process, and the assembly effect is improved.

Because the coupling adopts the design of frustum form, 8 bores of first bulge loop are greater than in this embodiment assemble 6 diameters of external screw thread, guarantee the fixed effect of assembly of two bulge loops to the pole.

In order to facilitate the quick snap-in of the first collar 8 or the second collar 9 into the first groove or the second groove in the pipe connection 4, the side 45 of the first groove or the second groove near the port side is rounded off.

It should be noted that the drawings provided in the above embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.

The utility model can also include other equivalent embodiments, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure should be included in the protection scope of the present disclosure.
