[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0033] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0034] This embodiment mainly describes the structure of a protective sleeve for an electric hammer cylinder, as detailed below:

[0035] like Figures 1-14 As shown, a hammer cylinder sleeve includes a housing 1 for accommodating a hammer cylinder 5, a plurality of fixing blocks 13 installed in the housing 1 for fixing and limiting the hammer cylinder 5, and a plurality of heat dissipation components 14 installed in the housing 1 for dissipating heat from the hammer cylinder 5. Thus, when the hammer cylinder 5 is working in the hammer cylinder sleeve, the heat dissipation components 14 can dissipate heat from the working hammer cylinder 5. In this way, when the hammer cylinder 5 is used for a long time, it can prevent the hammer cylinder 5 in the hammer cylinder sleeve from being damaged due to overheating. At the same time, in order to make the hammer cylinder sleeve have a shock absorption effect, the fixing blocks 13 are all made of hard rubber, and the fixing blocks 13 are attached to the outer wall of the hammer cylinder 5 on the side connected to the hammer cylinder 5.

[0036] The heat dissipation components 14 all include heat-conducting rods 141 installed in the housing 1. One end of the heat-conducting rod 141 abuts against the outer wall of the electric hammer cylinder 5, while the other end slides out of the housing 1. In this way, the heat generated when the electric hammer cylinder 5 is working can be transferred to the outside of the housing 1 through the heat-conducting rod 141 that abuts against the outer wall of the electric hammer cylinder 5, thereby achieving the effect of heat dissipation for the electric hammer cylinder 5. At the same time, since the heat-conducting rod 141 slides out of the housing 1 at the end away from the outer wall of the electric hammer cylinder 5, it is convenient to remove the heat-conducting rod 141 from the housing 1, thus facilitating the replacement of the heat-conducting rod 141.

[0037] To improve the heat dissipation effect of the heat-conducting rod 141 on the electric hammer cylinder 5, a heat-conducting block 145 with a diameter larger than that of the heat-conducting rod 141 is provided at one end of the heat-conducting rod 141 near the electric hammer cylinder 5. The heat-conducting rod 141 abuts against the outer wall of the electric hammer cylinder 5 through the heat-conducting block 145. This increases the contact area between the heat-conducting rod 141 and the outer wall of the electric hammer cylinder 5, thus transferring more heat to the heat-conducting rod 141 and improving the heat dissipation effect of the heat-conducting rod 141 on the electric hammer cylinder 5.

[0038] To facilitate replacement of the heat-conducting rod 141, the end of the heat-conducting rod 141 protruding from the housing 1 is slidably connected to the housing 1. However, when using the heat-conducting rod 141 to dissipate heat from the electric hammer cylinder 5, the heat-conducting rod 141 will cause the heat-conducting block 145 to separate from the outer wall of the electric hammer cylinder 5. Thus, the heat-conducting rod 141 no longer has the effect of dissipating heat from the electric hammer cylinder 5. To avoid this problem, a connecting sleeve 142 made of elastic material is fitted onto the heat-conducting rod 141 located in the housing 1. The connecting sleeve 142 has an I-shaped cross-section. The heat-conducting rod 141 passes through the connecting sleeve 142 before protruding from the housing 1. One end of the connecting sleeve 142 abuts against the inner wall of the housing 1, and the other end abuts against the outer wall of the electric hammer cylinder 5. Finally, a recess for accommodating the heat-conducting block 145 is provided at the end of the connecting sleeve 142 that abuts against the outer wall of the electric hammer cylinder 5. The groove 144 is provided, and when the heat-conducting block 145 is located in the receiving groove 144, the outer wall of the heat-conducting block 145 is flush with the side wall of the connecting sleeve 142. In this way, when the electric hammer cylinder 5 is located in the housing 1, the outer wall of the electric hammer cylinder 5 will squeeze the connecting sleeve 142. Since the connecting sleeve 142 is made of elastic material, when the connecting sleeve 142 is squeezed, it can drive the heat-conducting block 145 located in the receiving groove 144 to press against the outer wall of the electric hammer cylinder 5. Thus, when the heat-conducting rod 141 is used to dissipate heat from the electric hammer cylinder 5, the heat-conducting rod 141 will no longer drive the heat-conducting block 145 to separate from the outer wall of the electric hammer cylinder 5, thereby ensuring the stability of the heat-conducting rod 141 in the housing 1. At the same time, in order to improve the support strength of the connecting sleeve 142, a spring 143 is fitted on the connecting sleeve 142, and the top and bottom of the spring 143 are connected to the top and bottom of the connecting sleeve 142, respectively.

[0039] Furthermore, in order to improve the heat dissipation effect of the heat dissipation component 14 on the electric hammer cylinder 5, a plurality of heat dissipation plates 6 are provided on the outer wall of the housing 1 and are detachably connected to the housing 1. The inner wall of the heat dissipation plate 6 abuts against the heat conduction rod 141 that extends out of the housing 1. At the same time, a plurality of heat dissipation fins 8 are evenly provided on the outer wall of the heat dissipation plate 6.

[0040] Furthermore, to facilitate the installation of the heat sink 6 onto the outer wall of the housing 1, an installation groove 10 is provided on the outer wall of the housing 1 to accommodate the heat sink 6. At the same time, the end of the heat-conducting rod 141 that protrudes from the housing 1 is located in the installation groove 10, and the heat sink 6 is detachably connected to the housing 1 by bolts 7.

[0041] In order to connect the electric hammer cylinder 5 sleeve to other components, multiple connecting seats 9 are evenly arranged on the outer wall of the housing 1, and connecting holes 91 are opened on the connecting seats 9. In order to avoid the problem of the heat sink 8 being crushed when the electric hammer cylinder 5 sleeve is connected to other components, the height of the connecting seat 9 is set to be higher than the height of the heat sink 8.

[0042] To prevent dust and other impurities from entering the housing 1 from the point where the heat-conducting rod 141 passes through the housing 1, a rubber sleeve 16 is embedded at the connection between the housing 1 and the heat-conducting rod 141. At the same time, the inner wall of the rubber sleeve 16 is tightly fitted with the outer wall of the heat-conducting rod 141, and the outer wall of the rubber sleeve 16 is tightly fitted with the housing 1.

[0043] In order to improve the firmness of the connection between the heat-conducting rod 141 and the connecting sleeve 142, a plurality of elastic clamping rings 146 are evenly embedded in the connecting sleeve 142, and the elastic clamping rings 146 abut against the outer wall of the heat-conducting rod 141.

[0044] To facilitate the disassembly and assembly of the electric hammer cylinder 5, both ends of the housing 1 are open. At each of the two openings of the housing 1, there is a plug for sealing the housing 1, namely a first plug 2 and a second plug 3. The housing 1 has at least four through holes 12 penetrating it. The first plug 2 has four second through holes 15 aligned with the first through holes 12, penetrating the first plug 2. The second plug 3 has four screw holes 31 aligned with the first through holes 12 on one side wall near the housing 1. Finally, four studs 4 are installed on the first plug 2, passing through the second through holes 12. Hole 15 and the first through hole 12 are screwed into screw hole 31. The output end of the electric hammer cylinder 5 passes through the first plug 2. When installing the electric hammer cylinder 5 into the housing 1, firstly, place the electric hammer cylinder 5 into the housing 1, then install the first plug 2 and the second plug 3 into the opening of the housing 1 respectively, then insert the stud 4 from the second through hole 15 on the first plug 2 and let it pass through the first through hole 12 in the housing 1, and then screw it into the screw hole 31 on the second plug 3. Then tighten the stud 4. In this way, the electric hammer cylinder 5 is installed into the housing 1. When removing the electric hammer cylinder 5 from the housing 1, only the four studs 4 need to be removed. This makes it convenient to disassemble and assemble the electric hammer cylinder 5.

[0045] Furthermore, in order to further improve the shock absorption effect of the sleeve of the electric hammer cylinder 5, a shock-absorbing block 11 is provided on the side wall of the first cover 2 and the second cover 3 near the electric hammer cylinder 5, and the shock-absorbing block 11 can abut against the electric hammer cylinder 5.

[0047] The above provides a detailed description of the electric hammer cylinder sleeve provided by this utility model.
