Description

Technical Field

[0001] This utility model relates to the field of hammer technology, specifically to a shock-absorbing hammer with adjustable buffering force. Background Technology

[0002] To improve the comfort of hammer use, most hammers nowadays have a layer of shock-absorbing rubber wrapped around their surface to provide some shock absorption. However, when using such shock-absorbing hammers, the rubber wrapped around the hammer head directly collides with the object being hammered, making it prone to damage. Furthermore, because the rubber is directly fixed to the hammer surface, it is difficult to replace after damage. Also, because the rubber is directly wrapped around the hammer surface, its shock absorption force cannot be adjusted, making it difficult to meet the hammering needs of different situations. To address these issues, we propose technological innovations based on existing shock-absorbing hammers. Utility Model Content

[0003] The purpose of this invention is to provide a shock-absorbing hammer with adjustable buffering force to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing hammer with adjustable buffering force, comprising:

[0005] The hammerhead has a through groove on its left side. A hammering block and a pressure block are respectively placed on the left and right sides of the inner sidewall of the groove. A rubber shock-absorbing column is placed between the hammering block and the pressure block. The pressure block has a first threaded hole and a second threaded hole on its upper and lower sides. A fixing component is placed on the outer side of the pressure block.

[0006] Preferably, a set of positioning grooves is provided on the opposite sides of the hammer block and the pressure block, the left and right sides of the rubber shock-absorbing column are respectively located in the two sets of positioning grooves, and a handle is provided at the bottom of the hammer head.

[0007] Preferably, the left side of the hammer block passes through the left side of the slide groove and is located on the left side of the hammer head, and the right side of the pressure block passes through the right side of the slide groove and is connected to a pressure plate.

[0008] Preferably, the inner sidewall of the chute is uniformly provided with limiting grooves, and the outer sidewall of the hammer block is uniformly provided with limiting blocks, which are disposed in the limiting grooves.

[0009] Preferably, the fixing component includes a spring and a cross bolt. A round-headed pin is provided on the right side of the spring, and a magnet is embedded on the right side of the round-headed pin. A positioning hole is provided on the outer side of the screw head of the cross bolt. The round head of the round-headed pin is inserted into the positioning hole, and the magnet is magnetically attracted to the positioning hole.

[0010] Preferably, a set of countersunk holes are provided on both the upper and lower sides of the hammer head. The countersunk holes are connected to the sliding groove. The inner sidewall of the countersunk hole is provided with a mounting hole. The spring is fixedly installed in the mounting hole. The round-headed pin is slidably installed in the mounting hole. The cross bolt passes through the countersunk hole and is screwed into the first threaded hole, and corresponds to the second threaded hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a hammer block to strike an object, which absorbs the impact force transmitted by the hammer block through a rubber shock absorber column, thereby achieving a buffering and shock-absorbing effect. Furthermore, by moving the pressure plate to drive the pressure block to squeeze the rubber shock absorber column, the hardness of the rubber shock absorber column can be increased, reducing its buffering and shock-absorbing properties, thus adjusting the buffering and shock-absorbing force of the rubber shock absorber column.

[0013] When using a cross bolt to fix the position of the pressure block, a spring drives a round-headed pin to insert into the positioning hole of the cross bolt. At the same time, the magnetic attraction of the magnetic block can improve the insertion stability of the round-headed pin, thereby locking the cross bolt in the countersunk hole of the hammer head. This prevents the cross bolt from loosening due to vibration generated by the hammer during use, thus improving the reliability of use.

[0014] When the rubber shock absorber needs to be replaced due to failure, simply unscrew the cross bolt, then move the pressure plate to the right to separate the pressure block from the hammer head, and then pour the rubber shock absorber into the hammer head for replacement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3 An adjustable damping hammer includes a hammerhead 1. A sliding groove is formed through the left side of the hammerhead 1. A hammering block 13 and a pressure block 15 are respectively placed on the left and right sides of the inner wall of the sliding groove. A rubber damping column 16 is placed between the hammering block 13 and the pressure block 15. A first threaded hole 2 and a second threaded hole 21 are formed on both the upper and lower sides of the pressure block 15. A fixing component is placed on the outer side of the pressure block 15. A set of positioning grooves is formed on the opposite sides of the hammering block 13 and the pressure block 15. The rubber damping column 16 is positioned on the left... The hammerhead 1 is fixedly mounted on the bottom of two sets of positioning grooves on the right sides. After the hammer block 13 is aligned with the object to be hammered, the hammer head 1 is controlled by the handle 11 to drive the hammer block 13 to hammer the object. When the hammer block 13 is impacted, it will squeeze the rubber shock absorber 16 inward. The rubber shock absorber 16 absorbs the impact force transmitted by the hammer block 13, thereby achieving a buffering and shock absorption effect. The left side of the hammer block 13 extends through the left side of the slide groove and is located on the left side of the hammer head 1. The right side of the pressure block 15 extends through the right side of the slide groove and is connected to the pressure plate 14. Limiting grooves are evenly spaced on the inner wall of the slide groove. Limiting blocks 17 are evenly fixedly installed on the outer wall of the hammer block 13. The limiting blocks 17 are slidably positioned within the limiting grooves. The limiting blocks 17 can limit the position of the hammer block 13, thereby preventing the hammer block 13 from sliding out of the slide groove of the hammer head 1. The fixing assembly includes a spring 3 and a cross bolt 12. A round-headed pin 31 is fixedly installed on the right side of the spring 3. The right side of the round-headed pin 31... The hammer 1 has a magnetic block 32 embedded in it. The screw head of the cross bolt 12 has a positioning hole on the outside. The round head of the round head pin 31 is inserted into the positioning hole. The magnetic block 32 is magnetically attracted into the positioning hole. A set of countersunk holes are opened through the upper and lower sides of the hammer head 1. The countersunk holes are connected to the sliding groove. The inner side wall of the countersunk hole has a mounting hole. The spring 3 is fixedly installed in the mounting hole. The round head pin 31 is slidably installed in the mounting hole. The cross bolt 12 passes through the countersunk hole and is screwed into the first threaded hole 2, and corresponds to the second threaded hole 21.

[0021] Working principle: After the cross bolt 12 is screwed through the countersunk hole of the hammer head 1 and the first threaded hole 2 on the surface of the pressure block 15, the pressure block 15 can be fixed in the groove of the hammer head 1. This stabilizes the rubber shock absorber 16 between the hammer block 13 and the pressure block 15. When the cross bolt 12 is tightened, the round head pin 31 is driven by the spring 3 to insert into the positioning hole of the cross bolt 12. At the same time, the magnetic attraction of the magnet 32 ​​can improve the insertion stability of the round head pin 31, thereby locking the cross bolt 12 in the countersunk hole of the hammer head 1, thus preventing the vibration generated by the hammer during use from causing the ten-knock shock to occur. When the cross bolt 12 becomes loose, after aligning the hammer block 13 with the object to be hammered, and using the handle 11 to control the hammer head 1 to drive the hammer block 13 to hammer the object, the hammer block 13 will be impacted and squeeze the rubber shock absorber 16 inward. In this way, the rubber shock absorber 16 absorbs the impact force transmitted by the hammer block 13, thereby achieving a buffering and shock absorption effect. It should be noted that the maximum impact force that the hammer can withstand should not exceed the hardness of the cross bolt 12. The hardness of the cross bolt 12 depends on the actual manufacturing material and processing technology of the cross bolt 12, which will not be elaborated here.

[0022] When adjusting the damping force of the rubber shock absorber 16, the hammer head 1 should be placed upright on the two sets of pads with the left side facing downwards, and the hammer block 13 should be positioned between the two sets of pads and suspended in the air. At this time, the cross bolt 12 should be unscrewed from the first threaded hole 2. By pressing down the pressure plate 14, the pressure block 15 should be driven to squeeze the rubber shock absorber 16 downwards. When the second threaded hole 21 is aligned with the cross bolt 12, the cross bolt 12 should be screwed into the second threaded hole 21 to fix the position of the pressure block 15. By squeezing the rubber shock absorber 16, the hardness of the rubber shock absorber 16 is increased and its damping performance is reduced, thereby adjusting the damping force of the rubber shock absorber 16. It should be noted that when squeezing the rubber shock absorber 16 downwards, if manpower is limited, an external hydraulic press can be used.

[0023] When the rubber shock absorber 16 fails and needs to be replaced, simply unscrew the cross bolt 12, then move the pressure plate 14 to the right to separate the pressure block 15 from the hammer head 1, and then pour the rubber shock absorber 16 out of the hammer head 1 for replacement.
