Abstract

The utility model provides an extension sword, which includes a sword body and a sword grip connected with the sword body. The sword body comprises a plurality of sections of hollow bodies, all sections of the hollow bodies are inserted into each other, and two adjacent hollow bodies are extensible. Each of the hollow bodies is shaped by pressing a steel sheet; the interfaces of the shaped steel sheets are connected by laser welding. The extension sword has the advantages of convenient assembly and welding as well as low production cost.

Description

A kind of Extension sword

Technical field:

The utility model relates to a kind of outdoor activity articles for use, especially a kind of Extension sword.

Background technology:

Extension sword of the prior art, comprise sword body and connected pommel, the sword body is made up of some joint ducted bodies, and each saves the mutual socket of ducted body, scalable between the adjacent two joint ducted bodies, wherein, each saves ducted body forms by two identical formation of lots pieces of shape, after the butt joint of two formation of lots pieces, the interface of its both sides is welded to connect by argon arc, this Extension sword is in light weight, and is easy to use, but also exists deficiency:

The first, the soldering opening of argon arc welding is more poor, makes that the sword body is rough, needs to increase the operation of polishing aborning, could guarantee the smoothness on sword body surface, has improved production cost;

The second, each saves ducted body when carrying out erection welding, needs special anchor clamps to clamp and locate, and simultaneously, needs two interfaces of welding, and very inconvenience and workload are big when assembling and welding to make it, have reduced production efficiency.

The utility model content:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of Extension sword of being convenient to erection welding and low production cost is provided.

A kind of Extension sword that provides according to the utility model, comprise sword body and connected pommel, described sword body is made up of some joint ducted bodies, each saves the mutual socket of ducted body, scalable between the adjacent two joint ducted bodies, the described ducted body that respectively saves all has an interface by steel thin plate compression moulding on the steel thin plate after the moulding, this interface connects by laser weld.

According to a kind of Extension sword that the utility model provides, also have following attached technical characterictic:

Interface on the steel thin plate after described each moulding, its interface two ends are directly docked and are connected by laser weld.

Interface on the steel thin plate after described each moulding, its interface one end bend inwards and form a draw-in groove, and the other end inserts draw-in groove and connects by laser weld.

The described cross sectional shape that respectively saves ducted body is rhombus.

A kind of Extension sword according to the utility model provides has following advantage with respect to prior art:

The first, the sword body interface of this Extension sword adopts the mode of laser weld to weld, and its soldering opening is very smooth, does not need to polish just can dispatch from the factory again, and has effectively lowered the production cost of this Extension sword.

The second, after the repressed moulding of this Extension sword sword body, its interface is directly docked and get final product by the laser weld connection, do not need to use special fixture, its erection welding is very convenient, makes its production efficiency obtain significant raising.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of first kind of method of attachment of interface in the utility model;

Fig. 3 is the structural representation of second kind of method of attachment of interface in the utility model.

The specific embodiment:

With reference to Fig. 1, Fig. 2, a kind of Extension sword that provides according to the utility model, comprise sword body 1 and connected pommel 2, sword body 1 is made up of some joint ducted bodies 11, and each saves ducted body 11 mutual sockets, scalable between the adjacent two joint ducted bodies 11, each saves ducted body 11 respectively by a steel thin plate compression moulding, and the steel thin plate after each moulding all has an interface 12, and this interface 12 connects by laser weld.

Interface 12 on the steel thin plate after each moulding has two kinds of connected modes:

First kind, interface 12 two ends are directly docked and are connected by laser weld;

Second kind, interface 12 1 ends bend inwards and form a draw-in groove 13, and the other end inserts draw-in groove 13 and connects by laser weld.

Two kinds of methods of attachment of above-mentioned interface 12 can make the sword body 1 of this Extension sword very convenient when erection welding, have improved production efficiency significantly.

Each cross sectional shape that saves ducted body 11 is rhombus, also can be circular, square or other irregular figure.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
