Description

Technical Field

[0001] This utility model relates to the field of aluminum welding protection technology, and in particular to a foldable protective cover for aluminum welding. Background Technology

[0002] Aluminum alloy welding refers to the welding process of aluminum alloy materials. Aluminum alloys are high in strength and lightweight. The main welding processes are manual TIG welding (non-consumable electrode inert gas welding), automatic TIG welding, and MIG welding (consumable electrode inert gas welding).

[0003] During manual welding, sparks and intense light are generated at the welding point, which can easily cause irreversible damage to the face and eyes. Therefore, protective shields are needed to protect the faces of workers. Most existing protective shields are curved, and the area they can protect is fixed. This means that shields that are too small may not be able to protect the side of the worker's face, while shields that are too large are inconvenient to carry. Utility Model Content

[0004] This invention provides a foldable protective cover for aluminum welding, which solves the technical problem that the protection area of ​​existing protective covers is not adjustable.

[0005] To achieve this technical objective, the present invention adopts the following solution: a foldable protective cover for aluminum welding, comprising a main protective cover and a secondary protective cover;

[0006] The main protective cover has a protective observation window, and a handle is fixed to the bottom of the main protective cover;

[0007] The secondary protective shield is foldable and positioned on the side of the main protective shield to expand the protective area of ​​the main protective shield.

[0008] Furthermore, the secondary protective cover and the primary protective cover are rotatably connected by hinges, which are located on the inner sides of the primary and secondary protective covers.

[0009] Furthermore, the outer sides of the main protective shield and the outer sides of the secondary protective shield are connected by a first limiting mechanism.

[0010] Furthermore, the first limiting mechanism includes a connecting block, a plug rod, a positioning frame, and a handle;

[0011] The connecting block is fixed on the outer wall of the main protective cover, and the connecting block has an insertion hole on the side facing the secondary protective cover;

[0012] One end of the insertion rod is inserted into the insertion hole, the rod body slides into the positioning frame, and the other end of the insertion rod extends out from inside the positioning frame;

[0013] The positioning frame is fixed to the outer wall of the secondary protective cover;

[0014] The handle is fixed to the other end of the plug.

[0015] Furthermore, the first limiting mechanism also includes a spring-back assembly, which includes a baffle, a compressed spring, and a guide rod;

[0016] The baffle is fixedly installed on the top and / or bottom surface of the insertion rod;

[0017] One end of the guide rod is fixedly connected to the baffle, and the other end of the guide rod can slide through the positioning frame;

[0018] The spring is sleeved on the outside of the guide rod, and the two ends of the spring abut against the baffle and the positioning frame, respectively.

[0019] Furthermore, a flexible block is fixed at the top and / or bottom of the main protective cover. One side of the flexible block is an arc-shaped surface. The flexible block has a limiting groove that penetrates the arc-shaped surface. The area of ​​the limiting groove penetrating the arc-shaped surface does not exceed one-third of the area of ​​the arc-shaped surface.

[0020] The top and / or bottom of the auxiliary protective cover are rotatably connected to a rotating block, and a limiting block with an arc-shaped side is fixed on the side of the rotating block. The limiting block is set in a limiting groove.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] The present invention discloses a foldable protective cover for aluminum welding, which is equipped with a secondary protective cover. The secondary protective cover is foldable and is located on the side of the main protective cover.

[0030] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0031] like Figures 1 to 5 As shown, this utility model provides a foldable protective cover for aluminum welding, including a main protective cover 1 and a secondary protective cover 2. The main protective cover 1 has a protective observation window 3 for workers to observe the welding point. A handle 4 is fixed at the bottom of the main protective cover 1. The secondary protective cover 2 is foldable and is located on the left and / or right sides of the main protective cover 1 to expand the protective area of ​​the main protective cover 1.

[0032] Furthermore, the secondary protective cover 2 and the main protective cover 1 are rotatably connected by a hinge 5, which is located on the inner side of both the main protective cover 1 and the secondary protective cover 2. The outer side of the main protective cover 1 and the outer side of the secondary protective cover 2 are connected by a first limiting mechanism 6. The first limiting mechanism 6 is used to keep the secondary protective cover 2 in the unfolded state and prevent it from folding.

[0033] like Figure 2 As shown, the first limiting mechanism 6 includes a connecting block 61, a rod 62, a positioning frame 63, and a handle 64. The connecting block 61 is fixed to the outer wall of the main protective cover 1, and has an insertion hole on the side facing the secondary protective cover 2. One end of the rod 62 is inserted into the insertion hole, and the rod body of the rod 62 is slidably inserted into the positioning frame 63. The other end of the rod 62 extends out from the inside of the positioning frame 63. The positioning frame 63 is fixed to the outer wall of the secondary protective cover 2. The handle 64 is fixed to the other end of the rod 62. The handle 64 cannot pass through the positioning frame 63, thus playing a limiting role.

[0034] Furthermore, the first limiting mechanism 6 also includes a spring-loaded assembly 65, which includes a baffle 651, a compressed spring 652, and a guide rod 653. The baffle 651 is fixedly disposed on the top surface and / or bottom surface of the insert rod 62. One end of the guide rod 653 is fixedly connected to the baffle 651, and the other end of the guide rod 653 slidably passes through the positioning frame 63. The spring 652 is sleeved on the outside of the guide rod 653, and both ends of the spring 652 abut against the baffle 651 and the positioning frame 63, respectively.

[0035] In use, pull handle 64 with one hand to further compress spring 652, moving the right end of insert rod 62 as far away from connecting block 61 as possible. Then, rotate the secondary protective cover 2 with the other hand until it can no longer rotate. At this point, the right end of insert rod 62 is aligned with the insertion hole on connecting block 61. Release handle 64, and under the restoring force of spring 652, the right end of insert rod 62 is inserted into the insertion hole. At this point, insert rod 62 cannot slide out of the insertion hole without external force, thus preventing hinge 5 from folding and acting as a limit.

[0036] Preferably, the insertion hole on the connecting block 61 should have a certain depth to prevent the insertion rod 62 from sliding out of the insertion hole at will and failing to achieve the limiting effect.

[0037] Furthermore, a flexible block 7 is fixed to the top and / or bottom of the main protective cover 1. The flexible block 7 can be made of rubber. One side of the flexible block 7 is an arc-shaped surface 71. The flexible block 7 has a limiting groove 72 that penetrates the arc-shaped surface 71. The area of ​​the limiting groove 72 penetrating the arc-shaped surface 71 does not exceed one-third of the area of ​​the arc-shaped surface 71 (i.e., Figure 4 The area of ​​the gap 73 does not exceed one-third of the area of ​​the arc surface 71, so that the limiting groove 72 can play the role of wrapping the limiting block 81, making it difficult for the limiting block 81 to slide out of the limiting groove 72.

[0038] The top and / or bottom of the auxiliary protective cover 2 are rotatably connected to a rotating block 8, and a limiting block 81 with an arc-shaped side is fixed on the side of the rotating block 8. The limiting block 81 is set in the limiting groove 72.

[0039] The limiting block 81 and the limiting groove 72 are designed to keep the secondary protective cover 2 in a folded state and prevent it from unfolding. In use, first pull the insert rod 62 out of the connecting block 61, then manually bend the arc-shaped surface 71 to widen the gap 73, rotate the secondary protective cover 2, and insert the limiting block 81 into the limiting groove 72. Then, loosen the arc-shaped surface 71 so that the inner wall of the limiting groove 72 fits against the limiting block 81, preventing the limiting block 81 from sliding out of the limiting groove 72, thereby preventing the secondary protective cover 2 from unfolding.

[0040] Preferably, the volume of the limiting block 81 is greater than the volume of the limiting groove 72, that is, when the limiting block 81 is in the limiting groove 72, the limiting block 81 pushes the limiting groove 72 outward.

[0041] When welding aluminum, unfold the secondary protective cover 2 and hold the handle 4 by hand for protection. After welding, fold the secondary protective cover 2 to reduce its size and facilitate transportation.

[0042] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
