Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding slag hammer with a shock-absorbing handle. Background Technology

[0002] Electric welding is a welding operation that uses a welding rod to melt the metal parts that need to be joined by the high temperature of an electric arc. Electric welding is a common operation in the construction of various mechanical equipment and pipeline installation. Generally, after welding, there will be a certain amount of welding slag on the surface. Welding slag is a hard and brittle substance that covers the weld metal after welding. Workers usually use a hammer to remove the welding slag.

[0003] The utility model patent application publication number CN222155462U discloses a welding slag hammer. When the welded part is a workpiece that is easily deformed by hammering, a scraping head can be used instead of a hammering head to break up the welding slag, so as to avoid deformation of the workpiece.

[0004] However, the hammer handle in the above solution is just a single metal rod and does not have a shock absorption function. When workers use this hammer handle for a long time, they will inevitably feel soreness and discomfort in their wrists and arms, which will reduce their work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a welding slag hammer with a shock-absorbing handle to solve the problems mentioned in the background art.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0028] For examples, please refer to Figure 1-5 This utility model provides a technical solution:

[0029] A welding slag hammer with a shock-absorbing handle includes a hammer head 1, a hammer rod 2 fixedly connected to the bottom of the hammer head 1, a groove on one side of the hammer head 1, a connecting block 4 inserted into one side of the hammer head 1 through the groove, a scraping head 5 fixedly connected to the side of the connecting block 4 away from the hammer head 1, connecting components 6 for fixing the connecting block 4 symmetrically arranged on the upper and lower sides inside the hammer head 1, a shock-absorbing handle 3 for shock absorption of the hammer head 1 and the hammer rod 2, and snap-fit ​​holes 7 symmetrically opened on the upper and lower sides of the connecting block 4.

[0030] The shock-absorbing handle 3 includes a housing 301 located at the bottom of the hammer rod 2. A rubber sleeve 302 is fitted on the outer wall of the housing 301. A movable handle 303 is located in the middle of the inner cavity of the housing 301. The top of the movable handle 303 passes through the top of the housing 301 and is fixedly connected to the bottom of the hammer rod 2. The bottom of the hammer rod 2 is slidably connected to the top of the housing 301. A groove 304 is provided at the bottom of the inner cavity of the housing 301. Slider 305 is fixedly connected to both ends of the bottom of the movable handle 303.

[0031] The bottom ends of both sliders 305 extend into the interior of the slide groove 304 and are slidably connected to the inner wall of the slide groove 304. Shock-absorbing material blocks 306 are provided on both sides of the movable handle 303. The shock-absorbing material blocks 306 are made of TPU foam. Movable plates 307 are fixedly connected to the side of the two shock-absorbing material blocks 306 away from the movable handle 303. Airbags 308 are equidistantly connected to the side of the two movable plates 307 away from the shock-absorbing material blocks 306. The ends of the two airbags 308 away from the movable plates 307 are fixedly connected to the inner walls of the two sides of the outer shell 301. When the hammer head 1 strikes the welding slag, the vibration is transmitted to the movable handle 303, which drives the sliders 305 to slide in the slide groove 304. At the same time, the movable handle 303 squeezes the shock-absorbing material blocks 306, which causes the movable plates 307 to move, thereby squeezing the airbags 308 and squeezing the air inside the airbags. The elasticity of the shock-absorbing material blocks 306 and the airbags 308 absorbs and disperses the vibration, preventing the vibration from being directly transmitted to the worker's wrists and arms.

[0032] The connecting assembly 6 includes two symmetrically arranged adjustment cavities 601 on the upper and lower sides inside the hammer head 1. The two adjustment cavities 601 are respectively arranged on the upper and lower sides of the groove inside the hammer head 1. Rotating blocks 603 are rotatably connected to the upper and lower sides of the hammer head 1. The cross-section of the two rotating blocks 603 is hexagonal. The inner cavity of the two adjustment cavities 601 is provided with lead screws 602. The opposite ends of the two lead screws 602 are rotatably connected to the inner walls of the two adjustment cavities 601 respectively. The ends of the two lead screws 602 that are far apart from each other extend to the outside of the two adjustment cavities 601 and are fixedly connected to the surface of the two rotating blocks 603.

[0033] The outer walls of the two lead screws 602 are threaded with moving blocks 604. One side of the two moving blocks 604 is slidably connected to the inner wall of the two adjusting cavities 601 respectively. The other side of the two moving blocks 604 is fixedly connected with L-shaped locking rods 605. The ends of the two L-shaped locking rods 605 away from the moving blocks 604 are respectively inserted into the inside of the two locking holes 7.

[0034] Rotating the two rotating blocks 603 causes the lead screw 602 to rotate, which in turn causes the moving block 604 to move. The moving block 604 then causes the L-shaped locking rod 605 to move, so that one end of the L-shaped locking rod 605 leaves the inside of the locking hole 7. At this point, the connecting block 4 and the scraping head 5 can be pulled out from the inside of the hammer head 1, making it convenient to replace the scraping head 5.

[0035] In this embodiment, when the hammer 1 is used to strike the welding slag, the vibration is transmitted to the movable handle 303, which drives the slider 305 to slide in the groove 304. At the same time, the movable handle 303 squeezes the shock-absorbing material block 306, which causes the moving plate 307 to move, thereby squeezing the airbag 308 and squeezing the air inside the airbag. The elasticity of the shock-absorbing material block 306 and the airbag 308 absorbs and disperses the vibration, preventing the vibration from being directly transmitted to the worker's wrist and arm, reducing soreness and discomfort caused by prolonged use, and improving work comfort and efficiency.

[0036] The working process of this utility model is as follows: During use, the hammer head 1 and scraper head 5 can strike and scrape the welding slag, thus facilitating its removal. When the scraper head 5 needs replacement due to wear, the two rotating blocks 603 are rotated. The rotating blocks 603 drive the lead screw 602 to rotate, which in turn drives the moving block 604 to move. The moving block 604 then moves the L-shaped locking rod 605, causing one end of the L-shaped locking rod 605 to leave the inside of the locking hole 7. At this point, the connecting block 4 and scraper head 5 can be pulled out from inside the hammer head 1, facilitating the replacement of the scraper head 5. When the hammer head 1 is used to strike the welding slag... The resulting vibration is transmitted to the movable handle 303, which drives the slider 305 to slide inside the groove 304. At the same time, the movable handle 303 compresses the shock-absorbing material block 306, which drives the moving plate 307 to move. The moving plate 307 compresses the airbag 308, causing the air inside the airbag 308 to be compressed. Thus, the elasticity of the shock-absorbing material block 306 and the airbag 308 is used to absorb and disperse the vibration, preventing the vibration from being directly transmitted to the wrists and arms of the workers. This reduces the soreness and discomfort in the wrists and arms caused by prolonged use, and improves work comfort and efficiency.
