Description

AC arc welder

Technical Field

The utility model relates to the field of arc welders, in particular to an alternating current arc welder.

Background

The arc welder is also called arc welding transformer, which is a special transformer to change the AC of network voltage into the low voltage AC suitable for arc welding, and consists of main transformer, required regulating part, indicator, etc.

At present, when the arc welder works, the cable is used for external circuit connection, so that the arc welder can work, and the work is finished. After the cable is manually removed, the arc-welded connection port can be exposed in the air, and the height of the connection port is only a few centimeters away from the ground, so that the connection port has a certain risk to a certain extent.

If after the cable is pulled out, the water stain is stuck on the connection port, and the water stain is not evaporated in a short time, so that the arc welder is easy to generate electric leakage in the continuous use process by manpower. Although most arc welding machines on the market are provided with leakage protection devices, the situation that a cable protection skin is damaged cannot be avoided in the manual plugging process, and once the situation occurs, a user can lose intuition in a very short time by current, so that the life of the user is threatened.

Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making creative efforts based on the embodiments of the present utility model are included in the protection scope of the present utility model.

Referring to the drawings, the present embodiment provides an ac arc welding machine, which includes an arc welding machine body 1, a groove 11 is formed at one end of the arc welding machine body 1, a blocking groove 12 is formed at an inner edge of the groove 11, and a blocking groove 12 smaller than the groove 11 is formed at an inner side of the groove 11, as shown in fig. 2. And a plurality of connectors are fixedly arranged in the groove 11 and are used for connecting external cables so as to enable the arc welding machine to operate.

As shown in fig. 2, a dust-proof shell 2 is fixedly installed on one side of the arc welder body 1, the inside of the dust-proof shell 2 is of a hollow structure and is penetrated by one end passing through the groove 11, and a limit button 21 is rotatably installed on the outer side edge of the dust-proof shell 2.

The inside horizontal slip of shield 2 has protection shield 3 (when shield 3 is in the inside of shield 2, is in the state of horizontal slip), and the one side fixed mounting of shield 3 has the connecting plate, and both sides fixed mounting has the pivot about the other end of connecting plate, and rotates between the pivot and installs the dwang, rotates on the periphery of dwang and installs connecting rod 31.

Wherein, there is a reset spring fixedly installed at both ends of the rotating shaft, and the reset spring has the function that when the protection plate 3 slides out of the dust-proof shell 2, the protection plate 3 can rotate by itself, so that the protection plate 3 can be attached to the groove 11, and as the blocking groove 12 is formed in the groove 11, the blocking groove 12 can keep the protection plate 3 in a vertical state and block the protection plate 3 from rotating continuously, as shown in fig. 1. And the rubber ring 311 is fixedly arranged at the inner side edge of the protective plate 3 (when the protective plate 3 is attached to the blocking groove 12), and the rubber ring 311 can block liquid and prevent the liquid from flowing into the groove 11, so that the safety of the connecting port in the groove 11 is protected.

The dust-proof housing 2 is provided with a through slot 22, and the connecting rod 31 has an L-shaped structure, so that an end of the connecting rod 31 away from the protection plate 3 can extend to the outside of the dust-proof housing 2, as shown in fig. 1. Manually pulling one end of the connecting rod 31 allows the protection plate 3 to horizontally slide inside the dust-proof case 2.

And one end of the connection rod 31, which is far from the protection plate 3, is fixedly provided with a spring 32, and the other end of the spring 32 is fixedly provided on the inner sidewall of the dust-proof case 2, as shown in fig. 3. After the connecting rod 31 drives the protection plate 3 to enter the dustproof shell 2, the connecting rod 31 can be limited by the limiting buckle 21, so that the connecting rod 31 cannot slide automatically. And after taking down spacing knot 21, can be under the effect of spring 32 the quick inside that drives protection shield 3 roll-off shield 2 of connecting rod 31 to under the effect of spring 32, can exert an outside force to connecting rod 31, thereby make connecting rod 31 can not slide easily, thereby guaranteed connecting rod 31's stability, and then guaranteed protection shield 3's stability.

The working principle is as follows: when the protection board 3 is located in the dust-proof shell 2, the limit buckle 21 is manually rotated, so that the spring 32 pushes the connecting rod 31 to horizontally slide, and the protection board 3 slides out of the dust-proof shell 2 in the sliding process.

After the protection plate 3 slides out of the dustproof shell 2, the protection plate 3 can rotate under the action of a reset spring, so that one side of the protection plate 3, on which the rubber ring 311 is arranged, can be attached to the blocking groove 12, and a connection port in the groove 11 is protected.

While the basic principles and main features of the present utility model and advantages of the present utility model have been shown and described, it will be understood by those skilled in the art that the present utility model is not limited by the foregoing embodiments, which are described in the foregoing specification merely illustrate the principles of the present utility model, and various changes and modifications may be made therein without departing from the spirit and scope of the utility model as defined in the appended claims and their equivalents.
