Description

Technical Field

[0001] The utility model relates to the field of welding masks, in particular to a special mask for welding special-shaped pin equipment. Background Art

[0002] Pins are a commonly used mechanical accessory, mainly used to fix various parts of the boiler and refractory materials or cooling materials, and to form a flameproof belt. However, special-shaped pins such as Y-shaped pins and V-shaped pins cannot be welded with a pin gun and can only be welded manually at fixed equipment points. Handheld or head-mounted welding masks can be used for protection during welding. Handheld welding masks have better ventilation and air permeability, and a better physical feel. However, welding special-shaped pins requires two people to cooperate in welding. One person needs to place the special-shaped pin at a fixed equipment point and stabilize it, and hold the welding mask for protection during welding. The other person needs to spot weld the stabilized pin and hold the welding mask for protection during welding. This method not only wastes human resources but also causes Currently, due to the lack of coordination between the two people, low work efficiency and inadequate protection have resulted in arc burns and other situations; using a head-mounted welding mask, it can be operated by one person, with one hand responsible for fixing the pins and the other hand responsible for welding. It is easy to operate and has high work efficiency. However, in order to play a better protective role, most of the existing head-mounted welding masks have good sealing. However, this design will lead to poor air permeability, physical discomfort, and it is easy to get heatstroke. In addition, the fixed equipment point of the pin is also positioned by observation through goggles, which may lead to inaccurate positioning, resulting in deviations in the subsequent welding position.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] Example 1: Figures 1 to 5 The special-shaped pin equipment welding mask shown includes a safety helmet 1. The safety helmet 1 can be a hemispherical structure that covers the entire top of the head, or a hollow top hat structure that only covers the front half of the top of the head. The hollow top hat structure is preferably used to increase the air permeability of the wearer's head and reduce the discomfort of wearing the mask for a long time. A mask body 2 covering the face is fixed to the lower position of one side of the safety helmet 1. The mask body 2 extends forward from the lower side of the safety helmet 1 to the lower front half of the safety helmet 1. When the user faces straight ahead, the mask body 2 does not cover the entire face. A protective goggles 20 is installed at the middle part of the mask body 2 opposite to the eyes. The protective goggles 20 include a protective goggles frame 21 and a protective lens 22. The protective goggles frame 21 is riveted and fixed to the mask body 2, and the protective lens 22 is clamped in the goggles frame. The protective goggles 20 observe the weld position and weld formation when welding special-shaped pins through filtering and reflection, and protect the eyes from damage by electric welding arc light. A plurality of fixing screws 11 are evenly arranged along the length direction of the connection between the cover body 2 and the safety helmet 1. The fixing screws 11 are used to connect the cover body 2 and the safety helmet 1, thereby ensuring the firmness of the connection. The cover body 2 is made of ABS material or red steel paper, and the safety helmet 1 is made of plastic material. ABS material is relatively light and has certain fire resistance. The use of ABS material for the cover body 2 can reduce the overall weight of the mask, reduce the weight burden of the user, and also have a good protective effect; red steel paper has high hardness, good quality, and very good fire resistance. The use of red steel paper for the cover body 2 has better quality, more durable, and more stable protective performance; the safety helmet 1 is made of plastic material, and lightweight PE or PP material can be selected, which has a certain protective effect, can protect the head, and can also better reduce the overall weight of the mask.

[0037] When in use, first put on the sweat-absorbing cloth strip to prevent forehead sweat from flowing into the eyes, and then put on the mask. The user first slightly deflects to the side of the face covered by the mask body 2, so as to observe the fixed position directly from the uncovered side with the naked eye. After the special-shaped pins are stabilized, deflect to the side not covered by the mask body 2, and observe the welding points with both eyes through the goggles and perform welding. Only one person is needed to stably place the special-shaped pins at the fixed equipment points and perform welding, which makes the cooperation more tacit, saves human resources and improves production efficiency. Since the mask body 2 only extends forward to the front half of the safety helmet 1 and does not completely cover the face, the fixed equipment points can be directly observed with the naked eye when placing the special-shaped pins, and the field of vision is wider and the placement position is more accurate. The mask is not closed and has good air permeability, which reduces the stuffiness during use and improves the experience.

[0038] Embodiment 2: Based on the embodiment 1, a preferred design is performed, in which a cover hoop 3 is fixed inside the safety helmet 1, such as Figure 3 As shown, the cover hoop 3 includes a head hoop 31 of an annular structure and a top band 32 integrally connected to the head hoop 31. The head is inserted into the cover hoop 3, the top band 32 is sleeved on the top of the head, and the head hoop 31 surrounds the top of the head. The top band 32 is adjusted in length by a buckle 36, and the head hoop 31 is adjusted in tightness by a rotating screw 33 set on the back of the head. The size of the head hoop 31 can be adjusted according to the head shape. The head hoop 31 and the top band 32 cooperate to stably fix the safety helmet 1 on the user's head. The cover hoop 3 is made of plastic material, preferably lightweight PE or PP material, which is more lightweight and durable, and has good supporting performance, and can support the safety helmet 1 and the cover body 2.

[0039] Embodiment 3: Based on the embodiment 1, a preferred design is performed, such as Figure 4 As shown, the headband 31 of the cover hoop 3 is integrally provided with a distance support 34 on both sides, and the distance support 34 is a horizontally arranged cylindrical structure. The adjusting screw 35 passes through the safety helmet 1 and the distance support 34 in sequence from the corresponding position, and the safety helmet 1 and the cover hoop 3 are fixed together by threaded connection, thereby ensuring the connection firmness of the safety helmet 1 and the cover hoop 3, and a gap is left between the inner side of the safety helmet 1 and the cover hoop 3 in the circumferential direction, so that when the mask of the device is put on, a certain gap will be left between the top of the head and the inside of the mask, which increases the air permeability and further improves the wearing comfort of the user, and also allows the mask body 2 to keep a farther distance from the face, making it easier to observe the fixed equipment point of the special-shaped pin with the naked eye. The length range of the distance support 34 is 1-2 cm. This distance range improves the air permeability without affecting the overall stability when wearing the mask, and also makes it easier to directly observe the fixed position of the special-shaped pin.

[0040] Embodiment 4: Based on Embodiment 1, the structure of the cover body 2 is optimally designed, such as Figure 1 and Figure 5As shown, the cover body 2 is a curved structure and matches the shape of the head. The upper part of the side of the cover body 2 close to the front of the helmet 1 (i.e., the side close to the face) extends along the bending direction of the helmet 1 to form an upper shielding plate 24, and the lower part extends along its tangent direction to form a lower shielding plate 25. The bottom of the upper shielding plate 24 is connected to the top of the lower shielding plate 25 through a horizontally arranged triangular plate 26 and fixed by riveting. Among them, the upper shielding plate 24 is used to cover the forehead part of the face, and the lower shielding plate 25 is at the same horizontal height as the protective glasses 20. The setting of the lower shielding plate 25 further strengthens the protection of the cover body 2 to the face, and will not block the fixed equipment point of the special-shaped pins observed by the naked eye. Deflecting the head during welding can also better block the welding arc. The horizontal width range of the shielding plate is 6-8cm, which can not only play a good protective role, but also will not block the line of sight. The width in this embodiment is 7cm.

[0041] Embodiment 5: Based on Embodiment 1, the cover body 2 is optimally designed, such as Figure 1 As shown, the lower edge of the mask body 2 is connected to a protective cloth 4 by riveting or sewing. The protective cloth 4 is made of fire-resistant cloth. In this embodiment, denim fabric is used. The protective cloth 4 is used to prevent the skin of the lower jaw and neck from being damaged by the spot welding arc, thereby increasing the protection range of the mask and isolating some welding smoke.

[0042] Further, such as Figure 5 As shown, the lower edge of the cover body 2 gradually tilts upward from front to back and transitions in a curve, which ensures the protection area of ​​the front side of the cover body 2 while preventing the bottom of the cover body 2 from being blocked by the shoulders and unable to deflect when the user deflects his head.

[0043] Furthermore, the front side height of the cover body 2 is 25 cm, the rear side height is 14 cm, and the upper side length is 43 cm. The mask made of the cover body 2 of this size has good protective performance.

[0044] The above embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
