[0042] The following describes in detail the overall structure, working principle, and technical effects of the cylinder dustproof component, the cylinder with the dustproof component, and the sanitation vehicle provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0043] Please refer to Figures 1 to 5 This embodiment provides a sanitation vehicle, which includes a vehicle body, an actuator, and a cylinder 100 with a dustproof component. One end of the cylinder 100 with the dustproof component is connected to the vehicle body, and the other end is connected to the actuator to drive the actuator. This sanitation vehicle can be a sweeper, snowplow, or snow removal vehicle. The actuator is selected according to the different types of sanitation vehicles and can be a sweeping disc, a roller sweeper, a suction nozzle, etc.
[0044] Please refer to Figures 1 to 5 The cylinder 100 with dustproof components includes a cylinder 110, a connector 130, and a sealed dust cover 150. The connector 130 is installed at the end of the piston rod 113 of the cylinder 110. The sealed dust cover 150 is sleeved on the outside of the piston rod 113 of the cylinder 110, with one end connected to the connector 130 and the other end connected to the front end cap 112 of the cylinder 110. The sealed dust cover 150 can extend and retract under the action of the connector 130. The connector 130 is provided with a ventilation channel 131, which connects the internal space of the sealed dust cover 150 with the external space.
[0045] In this embodiment, a sealed dust cover 150 is fitted over the piston rod 113 of the cylinder 110, with one end connected to the connector 130 and the other end connected to the front cover 112 of the cylinder 110. This allows the sealed dust cover 150 to extend and retract under the influence of the connector 130, effectively blocking dust and rainwater. A ventilation channel 131 is provided in the connector 130, connecting the internal space of the sealed dust cover 150 to the external space, thus facilitating ventilation during the extension and retraction of the sealed dust cover 150. Compared to existing breathable dust covers, this significantly improves the problem of dust and rainwater ingress.
[0046] Please refer to Figures 1 to 5 The cylinder 110 includes a cylinder barrel 111, a front end cap 112, a piston, and a piston rod 113. The piston is installed inside the cylinder barrel 111, and the front end cap 112 is also installed inside the cylinder barrel 111. The piston rod 113 extends from the front end cap 112 into the cylinder barrel 111 and connects to the piston. A connector 130 is connected to the end of the piston rod 113. The connector 130 can be a Y-type connector 130, a fisheye connector 130, an I-type connector 130, etc. The connector 130 is generally installed at the end of the piston rod 113 by means of threads.
[0047] In this embodiment, the connector 130 includes an assembly portion 132 and a connecting portion 133. The connecting portion 133 is disposed on one side of the assembly portion 132 and is connected to the connecting execution assembly. The other side of the assembly portion 132 is mounted to the piston rod 113 of the cylinder 110. The ventilation passage 131 is disposed in the assembly portion 132 and located at the outer periphery of the connecting portion 133. One end of the sealing dust cover 150 is sleeved on the outer periphery of the assembly portion 132.
[0048] In this embodiment, the ventilation channel 131 is set in the assembly part 132 of the connector 130, which can prevent the execution component connected to the connection part 133 from blocking the ventilation channel 131.
[0049] Normally, the assembly part 132 has a threaded hole on the side away from the connection, and the assembly part 132 is installed at the end of the piston rod 113 through the threaded hole.
[0050] Please refer to Figures 1 to 3 In this embodiment, the ventilation channel 131 is a ventilation hole 134 provided in the assembly part 132.
[0051] In this embodiment, the ventilation channel 131 is set as the ventilation hole 134, which can avoid the obstruction of the sealed dust cover 150.
[0052] It should be noted that the ventilation hole 134 needs to be set away from the threaded hole of the assembly part 132 and the connecting part 133.
[0053] Please refer to Figure 3 In this embodiment, the ventilation hole 134 includes a blind hole 135 disposed at one end of the assembly part 132 away from the connecting part 133 and a side hole 136 disposed on the side wall of the assembly part 132, and the side hole 136 communicates with the blind hole 135.
[0054] In this embodiment, the ventilation hole 134 is configured as a connected blind hole 135 and a side hole 136, so that the opening of the side hole 136 exposed on the outside of the sealing dust cover 150 is located on the side wall of the connector 130, thereby avoiding obstruction.
[0055] Of course, in some other embodiments of this application, the ventilation hole 134 may also directly penetrate the assembly part 132.
[0056] Please refer to Figures 1 to 5 Furthermore, the cylinder 100 with dustproof components also includes a filter 170, which is disposed in the ventilation port 134. In this embodiment, the filter 170 is disposed in the ventilation port 134 to filter dust and water, etc. The filter 170 can be a filter sheet. The filter 170 can be disposed at the opening of the ventilation port 134 located inside the sealed dustproof cover 150, or at the opening of the ventilation port 134 located outside the sealed dustproof cover 150.
[0057] In this embodiment, there are two ventilation holes 134, which are symmetrically arranged in the assembly part 132. This example provides two ventilation holes 134, so that even if one ventilation hole 134 is blocked, the other ventilation hole 134 can still provide ventilation.
[0058] Of course, in other embodiments of this application, the number of ventilation holes 134 can be set according to actual needs, such as one or more.
[0059] In this embodiment, the sealed dust cover 150 is made of rubber. The rubber material of the sealed dust cover 150 not only isolates dust and water but also facilitates manufacturing and assembly.
[0060] Please refer to Figures 1 to 5In this embodiment, the cylinder 100 with dustproof components also includes a clamp 190. The sealed dust cover 150 includes a first connecting pipe 151, a bellows pipe 152, and a second connecting pipe 153 connected in sequence. The first connecting pipe 151 is sleeved on the outside of the connector 130, and the clamp 190 is disposed on the outer periphery of the first connecting pipe 151 to fix the first connecting pipe 151 to the connector 130. One end of the vent 134 is open and communicates with the internal space of the sealed dust cover 150, and the other end of the vent 134 is open and communicates with the external space on the outside of the sealed dust cover 150. The second connecting pipe 153 is sleeved on the outer periphery of the front end cover 112 of the cylinder 110. In this embodiment, the sealed dust cover 150 is configured with the above structure, which allows for pre-installation during installation by sleeved with the first connecting pipe 151 and the second connecting pipe 153, facilitating assembly.
[0061] In this embodiment, a clamp 190 is also provided on the outer periphery of the second connecting pipe 153, and the clamp 190 fixes the second connecting pipe 153 to the front end cover 112 of the cylinder 110.
[0062] Please refer to Figure 4 and Figure 5 In some other embodiments of this application, the ventilation channel 131 is a flow groove 137 formed on the outer periphery of the assembly part 132.
[0063] In this embodiment, the ventilation channel 131 is set as a flow channel groove, which facilitates processing.
[0064] In this embodiment, the flow channel 137 is formed along the axial direction of the connector 130. This axial formation of the flow channel facilitates machining.
[0065] Of course, in some other embodiments of this application, the flow channel groove can also be inclined. Secondly, the flow channel groove may or may not penetrate the assembly part 132 of the connector 130, as long as it ensures that a portion is exposed after the sealing dust cover 150 is installed to achieve communication between the internal and external spaces.
[0066] Please refer to Figure 4 and Figure 5 In this embodiment, the cross-section of the flow channel 137 is semi-circular, which facilitates processing. Of course, in other embodiments of this application, the cross-section of the flow channel 137 can also be triangular, rectangular, etc. There are two flow channels 137, symmetrically arranged. Naturally, the number and position of the flow channels 137 can be set according to requirements; this embodiment does not limit the number and position of the flow channels 137.
[0067] In this embodiment, after the first connecting pipe 151 is sleeved on the connector 130, the side wall of the first connecting pipe 151 will surround the notch in the side wall of the flow groove 137, so that the flow groove 137 forms an airflow channel that is open to both the inside and outside, without obstructing the flow groove 137. A filter 170 can also be installed in the flow groove 137 to filter dust, water and other impurities.
[0068] In summary, this embodiment places the sealed dust cover 150 around the piston rod 113 of the cylinder 110, with one end connected to the connector 130 and the other end connected to the front cover 112 of the cylinder 110. This allows the sealed dust cover 150 to extend and retract under the influence of the connector 130, effectively blocking dust and rainwater. A ventilation channel 131 is provided in the connector 130, connecting the internal space of the sealed dust cover 150 to the external space, thus facilitating ventilation during the extension and retraction of the sealed dust cover 150. Compared to existing breathable dust covers, this significantly improves the problem of dust and rainwater ingress.
[0069] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
