[0024] The utility model provides a breaker hammer structure, including a connecting plate 101, a shell 102 and a spring assembly, wherein the spring assembly includes a first slide bar 107 and a second slide bar 108. The above-mentioned scheme solves the technical problem that since a plurality of springs are arranged in the shell 102, when replacing the springs, the shell 102 needs to be disassembled as a whole, and the replacement method is relatively cumbersome, thereby making it inconvenient to quickly replace the springs.

[0025] According to this specific embodiment, a hammer head 103 is provided on the lower end surface of the connecting plate 101, and two sliding holes 104 are provided on the connecting plate 101. An automatic reset hydraulic rod 105 is provided on the inner top of the shell 102. The upper and lower ends of the shell 102 each have two thread grooves 106. The connecting plate 101 is slidably connected to the shell 102 and is located inside the shell 102. The hammer head 103 passes through the bottom of the shell 102. Crushing operations can be performed through the hammer head 103, and the automatic reset hydraulic rod 105 can have a certain buffering effect on the connecting plate 101.

[0026] The two spring assemblies are symmetrically arranged in the housing 102, one end of the first slide bar 107 is provided with a positioning rod 109, one end of the second slide bar 108 has a positioning groove 110, the first slide bar 107 and the second slide bar 108 are sleeved with a spring body 111, the other ends of the first slide bar 107 and the second slide bar 108 are provided with a threaded column 112, the outer side of the threaded column 112 is provided with a threaded sleeve 113, one end of the threaded column 112 is provided with a threaded body 114, the threaded A rotating block 115 is provided at one end of the body 114, the first slide bar 107 and the second slide bar 108 are mutually supported and located below the second slide bar 108, and the positioning rod 109 is located in the positioning groove 110, the spring body 111 is welded to the threaded sleeve 113 and is located on the threaded sleeve 113, the threaded body 114 is threadedly connected to the housing 102 and is located in the corresponding threaded groove 106, the connecting plate 101 is sleeved on the first slide bar 107 and the second slide bar 108, and ... The spring bodies 111 on the first slide bar 107 and the second slide bar 108 are respectively held against the upper and lower end surfaces of the connecting plate 101. By providing the threaded groove 106 and setting the spring body 111 into a structure that is easy to disassemble, the assembly on which the spring body 111 is installed is taken out through the threaded groove 106, thereby realizing rapid replacement of the spring body 111. At the same time, the replacement method is simple and convenient. When working, the hammer head 103 will first contact the crushed object and will apply a reaction force to the hammer head 103. The hammer head 103 will push the connecting plate 101 upward, and the connecting plate 101 will squeeze the spring body 111 on the second sliding rod 108. Since the elasticity of the spring body 111 located at the top is stronger than that of the spring body 111 located at the bottom, the spring body 111 located at the top will push the connecting plate 101 downward, and the connecting plate 101 will squeeze the spring body 111 located at the bottom downward, and will drive the hammer head 103 to move downward quickly, so as to achieve the crushing of objects, which is beneficial to the crushing work of the staff.

[0027] Secondly, sliders 116 are provided at both ends of the connecting plate 101, and slide grooves 117 are provided on both inner sides of the shell 102. The sliders 116 are slidably connected to the shell 102 and are located in the slide grooves 117. The sliders 116 can improve the stability between the connecting plate 101 and the shell 102.

[0028] Again, a plurality of anti-skid protrusions 118 are provided on the outer side of the threaded sleeve 113 , and the threaded sleeve 113 can be easily rotated through the anti-skid protrusions 118 , thereby facilitating the removal of the threaded sleeve 113 and the spring body 111 .

[0029] When the spring body 111 is replaced by the utility model, the rotating block 115 is rotated to make the rotating block 115 drive the threaded body 114 to rotate in the thread groove 106, and the first slide bar 107 or the second slide bar 108 is taken out from the thread groove 106, and then the threaded sleeve 113 is rotated to remove the threaded sleeve 113 from the threaded column 112, and the new spring body 111 is sleeved on the threaded column 112. It should be noted that the threaded sleeve 113 is welded on the new spring body 111, and finally the threaded body 114 is connected to the thread groove 106, and the positioning rod 109 is located in the positioning groove 110, so as to complete the replacement of the spring body 111. This replacement method is simple and convenient, and any one of the spring bodies 111 can be replaced separately without completely disassembling the housing 102, thereby improving the replacement speed of the spring body 111.
