Description

Technical Field

[0001] This utility model belongs to the field of welding machine technology and relates to an electric welding machine. Background Technology

[0002] An electric welding machine uses the high-temperature electric arc generated when positive and negative electrodes are momentarily short-circuited to melt the welding rod and the material being welded, thus bonding the objects together. Electric welding machines use electrical energy, instantly converting electrical energy into heat energy. Electricity is readily available, and welding machines are suitable for working in dry environments with few special requirements.

[0003] Due to the complex working environment and severe dust pollution, welding machines without protective measures are exposed to outdoor environments for extended periods, which seriously affects their service life and greatly increases maintenance costs. Furthermore, welding machines are inconvenient for users to move and carry during use, causing inconvenience. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an electric welding machine that is easy to move and carry and has protective functions.

[0005] The objective of this utility model can be achieved through the following technical solution: A welding machine includes a welding machine body, characterized in that a protective shell is provided on the welding machine body, a handle for lifting is provided at the upper end of the protective shell, two fixing parts are respectively provided at both ends of the protective shell, the fixing parts are integrally formed with the protective shell, and two positioning components for positioning the protective shell are provided on each fixing part, the positioning components are composed of a positioning element, a sliding part and a return spring, the fixing part is provided with an installation groove for installing the positioning components, the welding machine body is provided with a positioning groove that cooperates with each positioning element, one end of the positioning element extends out of the installation groove and is locked in the positioning groove, the other end of the positioning element extends into the installation groove and is connected to the return spring, and the protective shell is fixed to the welding machine body by the positioning element engaging with the positioning groove of the welding machine body.

[0006] In the aforementioned welding machine, one end of the positioning member extends out of the fixing part and is connected to a pull rod, one end of the return spring is connected to the positioning member, and the other end of the return spring is connected to the fixing part.

[0007] In the aforementioned welding machine, the bottom of the main body of the welding machine is provided with four support bases for support.

[0008] In the aforementioned welding machine, there are two handles, and they are integrally formed with the protective shell.

[0009] Compared with existing technologies, this welding machine has a protective shell on the outside of the welding machine body, which protects the welding machine body. The protective shell is also detachable, making it easy for staff to replace. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] Figure 2 This is a cross-sectional structural diagram of the present invention.

[0012] In the diagram, 1 is the welding machine body; 2 is the protective shell; 3 is the handle; 4 is the fixing part; 5 is the positioning component; 6 is the positioning element; 7 is the sliding part; 8 is the return spring; 9 is the mounting groove; 10 is the positioning groove; 11 is the pull rod; and 12 is the support base. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, this welding machine includes a welding machine body 1, on which a protective shell 2 is provided. During installation, the protective shell 2 is attached to the outer shell of the welding machine body 1, thus providing protection for the welding machine body 1. The rear end of the welding machine body 1 has heat dissipation holes. The upper end of the protective shell 2 has a handle 3 for lifting. Two fixing parts 4 are respectively provided on both sides of the protective shell 2. The fixing parts 4 are integrally formed with the protective shell 2, and each fixing part 4 has two positioning brackets for positioning the protective shell. Positioning component 5, which consists of positioning element 6, sliding part 7 and return spring 8, has an installation groove 9 on the fixing part 4 for mounting the positioning component 5. The welding machine body 1 has a positioning groove 10 that cooperates with each positioning element 6. One end of the positioning element 6 extends out of the installation groove 9 and is locked in the positioning groove 10. The other end of the positioning element 6 extends into the installation groove 9 and is connected to the return spring 8. The protective shell is fixed to the welding machine body 1 by the locking of the positioning element 6 with the positioning groove 10 of the welding machine body 1.

[0015] To elaborate further, when installing the protective housing, by pulling the pull rod 11 extending out of the fixing part 4, the return spring 8 is compressed, causing the positioning part 6 to move into the mounting groove 9. After installation, the pull rod 11 is released, the return spring 8 rebounds, and the positioning part 6 extends out of the mounting groove 9 again and is engaged in the positioning groove 10 of the welding machine body 1.

[0016] To elaborate further, one end of the positioning member 6 extends out of the fixing part 4 and is connected to a pull rod 11. One end of the return spring 8 is connected to the positioning member 6, and the other end of the return spring 8 is connected to the fixing part 4.

[0017] To elaborate further, the bottom of the welding machine body 1 is provided with four support bases 12 for support.

[0018] To elaborate further, there are two handles 3, and they are integrally molded with the protective shell 2.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0020] Although this document frequently uses terms such as welding machine body 1, protective shell 2, handle 3, fixing part 4, positioning component 5, positioning element 6, sliding part 7, return spring 8, mounting groove 9, positioning groove 10, pull rod 11, and support base 12, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
