Description

Technical Field

[0001] This utility model belongs to the technical field of tractor parts production equipment, and in particular relates to a welding protection structure for a tractor lower lever support. Background Technology

[0002] Tractor lower control rod support is a key component of the tractor suspension system. It is mainly used to connect the lower control rod to the tractor rear axle and bear the traction force and impact load during agricultural implement operation. It requires a welding process during production, and welding equipment is usually used. Welding equipment is divided into two main categories: automatic welding equipment and manual welding equipment. Among them, manual welding equipment is mainly a welding torch, and the protective structure used for handheld welding torches is a protective mask.

[0003] Chinese patent application CN219375170U discloses a protective mechanism for welding operations, including a protective plate and a light-shielding lens. A support device and an angle adjustment device are provided below the protective plate. The support device includes a first support rod, a second support rod, a connecting rod, a third support rod, and a fourth support rod. The bottom of the second support rod is slidably connected to the first support rod. One end of the connecting rod is connected to the upper surface of the second support rod, and the other end is connected to the lower surface of the third support rod. The bottom of the fourth support rod is slidably connected to the third support rod. This utility model features a support device that facilitates the support of the protective plate, eliminating the need for welders to hold the protective plate by hand and preventing interference from the welder. Furthermore, the support device allows welders to easily provide auxiliary support or assist in the movement of the welding parts.

[0004] The aforementioned protective mechanism for welding operations mainly consists of two parts: a protective plate and a supporting structure. The protective plate is an arc-shaped plate structure with sun-shielding lenses embedded in it. Since the area of ​​the face requiring protection varies from person to person, an excessively large protective plate can cause excessive pressure on the supporting structure, potentially leading to its collapse. Conversely, an excessively small protective plate results in incomplete facial protection. Furthermore, the sun-shielding lenses are embedded in the protective plate and secured with screws at the four corners. These lenses are consumable parts, and replacement is difficult and time-consuming, thus delaying welding operations. Therefore, we provide a welding protective structure for a tractor lower control rod support to address these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a welding protection structure for a tractor lower lever support. Through the extension components inside both sides of the protective plate, the protective plate can be pulled out and fixed in position when needed, thereby increasing the protection area of ​​the protective plate. The observation components can achieve the effect of quick replacement of the lens plate, which is more suitable for production needs and solves the problems of the above-mentioned welding operation protection mechanism.

[0012] The present invention is further configured such that an elastic element is provided between the upper and lower side sliders, and an elastic element is also provided below the lower side slider. The elastic element is composed of a hollow column, a spring and a sliding column, and one end of the sliding column is slidably inserted into the hollow column, and the spring is provided inside the hollow column.

[0013] The present invention is further configured such that the abutment plate is slidably connected to the upper slot, and the abutment plate is fixedly mounted on the bottom side wall of the fixing strip. A magnetic absorbing sheet is embedded in the bottom side wall of the abutment plate, and a metal plate is embedded in the upper side wall of the frame. The metal plate is attracted to the magnetic absorbing sheet. Side plates are also fixedly mounted at both ends of the fixing strip, and the side plates are fixedly mounted at the upper end slot of the upper slot by fixing bolts.

[0014] This utility model has the following beneficial effects: This utility model incorporates a protective plate and an extension component. The protective plate has storage slots on both sides for installing and storing the extension component. Sliding grooves are formed on the upper and lower inner walls of the storage slots. The extension component includes an extension plate that slides into the storage slots, with sliding sleeves integrally formed at the ends of both the upper and lower side walls of the extension plate. The extension plate is also slidably connected to the sliding grooves via the sleeves. Insertion holes are evenly spaced on the upper side wall of the extension plate, and insertion rods are inserted into these holes. A pull ring is fixedly installed at the upper end of each insertion rod. The insertion rod is attached to the protective plate. Insert the rod from above the protective plate and extend it through the upper side wall of the protective plate into the insertion hole of the extension plate. When using it, first pull the pull ring and pull it upward to pull the rod out of the protective plate. Then, hold the extension plate from the side and pull it outward to make the extension plate slide outward in the storage groove of the protective plate. This achieves the effect of extending the protective area of ​​the protective plate. After adjusting the protective area, insert the rod again from above the protective plate and extend it through the upper side wall of the protective plate into the extension plate to fix the position of the extension plate.

[0015] This utility model incorporates a protective plate and an observation assembly. The upper sidewall of the protective plate has an upper slot extending to the lower middle portion. An observation slot is formed in the sidewall of the protective plate corresponding to the upper end of the upper slot. The observation assembly includes a fixing strip fixed to the upper end of the upper slot, with an abutment plate on the bottom sidewall of the fixing strip. Two frames are inserted into the lower middle portion of the upper slot, each frame inlaid with a lens plate. Side sliders are fixed to the side walls of the frames, allowing the frames to slide slidably to the upper slot. The lens plate in the upper frame faces the observation slot. Elastic elements are mounted on the side sliders of the frames, including a hollow column and a spring inside the hollow column. The hollow column is slidably inserted into the sliding column via the spring. The lower frame abuts against the upper frame via the elastic element, while the upper frame abuts against the bottom sidewall of the abutment plate via the elastic element, thereby stabilizing the frames. The upper lens plate is designed with a metal plate embedded in the upper side wall of the frame and a magnetic clasp embedded in the bottom side wall of the abutment plate. The magnetic clasp improves the connection stability between the frame and the abutment plate when they are in contact. When the lens plate is damaged and needs to be replaced, first remove the fixing bolts on both sides of the fixing strip. At this time, the elastic element is continuously compressed, which will push the fixing strip, the abutment plate, the frame above, and the damaged lens plate inside to move upward. Then, the fixing strip, the abutment plate, and the frame with the damaged lens plate can be pulled out. After removing the frame, the abutment plate is inserted back into the upper slot and the fixing strip is fixed. Then, the frame below will be pushed upward by the elastic element until the upper end of the frame abuts the bottom side wall of the abutment plate. At this time, the lens plate is exactly in the position of the observation slot, thus achieving a quick replacement effect. The removed damaged lens plate and its upper frame can be repaired separately. Attached Figure Description

An abutment plate 406 is also provided on the bottom side wall of the fixing strip 407, and the abutment plate 406 abuts against the upper side wall of the frame 401.

[0034] Furthermore, a metal plate 403 is also inlaid on the upper side wall of the frame 401, and a magnetic piece 406a is inlaid on the bottom side wall of the abutment plate 406. When the frame 401 and the abutment plate 406 abut against each other, the magnetic piece 406a will attract the metal plate 403, thereby improving the stability of the connection between the two. Side sliders 404 are integrally provided on both sides of the frame 401, and elastic elements 405 are also installed on the side sliders 404. The side sliders 404 on the lower frame 401 are connected to the bottom side wall of the slot 103 on the protective plate 1 through the elastic elements 405. At the same time, the side sliders 404 on the upper frame 401 are connected to the side sliders 404 on the lower frame 401 through the elastic elements 405. The elastic element 405 is composed of a hollow column 405a, a spring 405b and a sliding column 405c. One end of the sliding column 405c is slidably inserted into the hollow column 405a, and the spring 405b is disposed inside the hollow column 405a. When both frames 401 are in the upper slot 103, the elastic element 405 is always in a compressed state.

[0035] The operation process of this embodiment is as follows: When the lens plate 402 is damaged and needs to be replaced, first remove the fixing bolts 408 on both sides of the fixing strip 407. At this time, the elastic element 405 is continuously compressed, which will push the fixing strip 407, the abutment plate 406, the frame 401 located above, and the damaged lens plate 402 inside it to move upward. At this time, the fixing strip 407, the abutment plate 406, and the frame 401 with the damaged lens plate 402 can be pulled out. After removing the frame 401, the abutment plate 406 is inserted into the upper slot 103 again and the fixing strip 407 is fixed. Then, the frame 401 located below will be pushed upward under the action of the elastic element 405 until the upper end face of the frame 401 abuts against the bottom side wall of the abutment plate 406. At this time, the lens plate 402 is just located at the position of the observation slot 102, thereby achieving the effect of quick replacement. The removed frame 401 and the damaged lens plate 402 on it can be repaired separately.
