By providing the connecting assembly, the first shell and the second shell are connected to each other by fastening bolts and connecting columns, so that the disassembly and assembly of the outer shell is easier. Reinforcement grooves are provided on the surfaces of the first shell and the second shell, which not only saves materials of the first shell and the second shell, but also enhances the stress strength of the first shell and the second shell. Friction blocks are provided to reduce friction between objects and the first shell and the second shell. The connecting column and the connecting groove are set as an interference fit, which can enhance the stability between the first shell and the second shell, and the interference fit connecting column connection is more compact.

[0004] Regarding the above-mentioned related scheme, the friction block provided can reduce the friction between the object and the first shell and the second shell, so that the service life of the breaker hammer shell structure can be extended. However, since the friction block is fixedly connected to the first shell and the second shell, the friction block is gradually worn out due to long-term use and is difficult to disassemble and replace, which makes the use of the split breaker hammer shell structure more inconvenient.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] The following describes an embodiment of the present invention based on its overall structure.

[0023] A split breaker hammer shell structure, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a No. 1 shell 1, a No. 2 shell 2, a fastening bolt 3 and a connecting column 4. The fastening bolt 3 is provided through one end of the No. 1 shell 1 and the No. 2 shell 2, and the connecting column 4 is provided through the other end of the No. 1 shell 1 and the No. 2 shell 2;

[0024] See Figure 2 、 Figure 3 and Figure 4 It can be seen that the ends of the No. 1 and No. 2 housings 1 and 2 away from the fastening bolts 3 are both provided with friction blocks 5, and the ends of the friction blocks 5 close to the fastening bolts 3 are provided with plug-in plates 7. The ends of the No. 1 and No. 2 housings 1 and 2 close to the friction blocks 5 are both provided with plug-in slots 8 that match the plug-in plates 7. The friction blocks 5 and the No. 1 and No. 2 housings 2 all form a snap-fit ​​structure through the plug-in plates 7 and the plug-in slots 8. The plug-in plates 7 and the plug-in slots 8 are both symmetrically provided in two groups about the central axis of the friction block 5.

[0025] See Figure 2 、 Figure 3 and Figure 4It can be seen that after the plug-in board 7 is inserted into the plug-in slot 8, the friction block 5 can be preliminarily installed on the first shell 1 and the second shell 2, which can facilitate the subsequent installation and improve the firmness of the subsequent installation.

[0026] See Figure 2 、 Figure 3 and Figure 4 It can be seen that both ends of the positioning plate 603 are provided with limit blocks 9, and the interior of the limit blocks 9 is penetrated by a limit rod 10 connected to the No. 1 shell 1 and the No. 2 shell 2. The positioning plate 603 and the No. 1 shell 1 and the No. 2 shell 2 all form a sliding structure through the limit blocks 9 and the limit rod 10, which can play a role in supporting and limiting the positioning plate 603, thereby increasing the stability of the positioning plate 603 during the sliding process.

[0027] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It can be seen that the interior of the No. 1 shell 1 and the No. 2 shell 2 are both provided with a positioning mechanism 6 extending to the interior of the plug-in board 7, and the positioning mechanism 6 includes a push-pull plate 601, a connecting rope 602, a positioning plate 603, a positioning slot 604 and a support spring 605. A positioning slot 604 is provided on one side of the plug-in board 7, and the interiors of the No. 1 shell 1 and the No. 2 shell 2 are both slidably connected with the positioning plate 603, and the plug-in board 7 and the plug-in slot 8 form a locking structure through the positioning plate 603 and the positioning slot 604. One end of the positioning plate 603 is provided with an inclined surface, and the positioning plate 603 and the positioning slot 604 are both symmetrically provided with two groups about the central axis of the friction block 5. Support springs 605 are connected between the positioning plate 603 and the No. 1 shell 1 and the No. 2 shell 2, and the positioning plate 603 and the No. 1 shell 1 and the No. 2 shell 2 form an elastic structure through the support spring 605;

[0028] See Figure 2 、 Figure 3 and Figure 4 It can be seen that since the positioning plate 603 is elastically connected to the No. 1 shell 1 and the No. 2 shell 2 through the support spring 605, and one end of the positioning plate 603 is provided with an inclined surface, when the plug-in plate 7 at one end of the friction block 5 is inserted into the plug-in slot 8, the positioning plate 603 will be stuck into the positioning slot 604 under the action of the support spring 605, thereby realizing the installation of the friction block 5 on the No. 1 shell 1 and the No. 2 shell 2, which is beneficial to ensure the wear resistance of the split breaker shell structure.

[0029] See Figure 2 、 Figure 3 and Figure 4It can be seen that the ends of the first shell 1 and the second shell 2 that are away from each other are both slidably connected with a push-pull plate 601, and a connecting rope 602 that passes through a support spring 605 is connected between the push-pull plate 601 and the positioning plate 603;

[0030] See Figure 2 、 Figure 3 and Figure 4 It can be seen that since the positioning plate 603 and the push-pull plate 601 are linked by the connecting rope 602, the connecting rope 602 can drive the positioning plate 603 out of the positioning groove 604 by pushing the push-pull plate 601 upward. After moving the friction block 5 to one end, it can be disassembled. The operation process is simple and quick.

[0031] The working principle of the present invention is as follows: when using the split breaker hammer shell structure, the assembly between the No. 1 shell 1 and the No. 2 shell 2 is achieved by the cooperation of the fastening bolts 3 and the connecting column 4. When the friction block 5 needs to be replaced, the push-pull plate 601 can be pushed upward to make the connecting rope 602 drive the positioning plate 603 to disengage from the positioning groove 604. At this time, the friction block 5 can be moved to one end to make the plug-in plate 7 disengage from the plug-in groove 8. Then, the required friction block 5 is taken out, and the plug-in plate 7 at one end of the friction block 5 is inserted into the plug-in groove 8. During this process, the positioning plate 603 will be stuck in the positioning groove 604 under the action of the supporting spring 605, thereby realizing the installation of the friction block 5 on the No. 1 shell 1 and the No. 2 shell 2, thereby completing the replacement of the friction block 5, so that the wear resistance of the breaker hammer shell structure is guaranteed. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
