Description

Technical Field

[0001] The utility model relates to the technical field of crankcases, in particular to a crankcase that is easy to dissipate heat. Background Art

[0002] At present, there is a small-sized, multi-purpose high-pressure pump (such as patent number: CN203627120U), which discloses a high-pressure pump, which replaces the original crosshead and plunger rod with an integrated intermediate rod, so that the coaxiality is good and the assembly is convenient, and the volume of the product can be reduced. The crankcase and the rear cover are provided with heat dissipation fins, and the crankshaft end cover is formed with heat dissipation holes. At the same time, grooves are formed at the positions corresponding to the heat dissipation holes on the crankcase, and the middle part of the bottom surface of the crankcase is recessed upward. Therefore, these forced heat dissipation measures can dissipate the heat in the crankcase as soon as possible, so as not to affect the lubricating performance of the lubricating oil in the crankcase, thereby preventing the parts in the crankcase from being worn, thereby improving the service life of the entire product, and the provision of heat dissipation fins can also play an enhancing role at the same time.

[0003] However, in the process of implementing the above technical solution, it was found that there were at least the following problems: the crankcase is provided with cooling fins to facilitate heat dissipation of the crankcase. When the crankcase is used for a long time, dust and other impurities will be on the surface of the cooling fins. At the same time, the cooling fins will be worn during use. In order to ensure the heat dissipation effect, the cooling fins need to be cleaned or replaced regularly. Since the cooling fins are fixedly arranged on the outside of the crankcase, cleaning and replacement are difficult. Utility Model Content

[0022] The embodiment of the present application provides a crankcase that is easy to dissipate heat, thereby effectively solving the technical problem that the heat dissipation fins are fixedly arranged on the outside of the crankcase, which makes cleaning and replacement difficult.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The technical solution in the embodiment of the present application effectively solves the technical problem that the heat dissipation fins are fixedly arranged outside the crankcase, which makes cleaning and replacement difficult. The overall idea is as follows:

[0025] In view of the problems existing in the prior art, the utility model provides a crankcase with easy heat dissipation, which includes a case body 1, two heat dissipation fins 2 are arranged on the outside of the case body 1, and a fixing groove 3 is opened on the outside of each heat dissipation fin 2. Two connecting mechanisms are arranged on the outside of the case body 1, and each connecting mechanism includes a threaded rod 4, a fixing plate 5, a fixing block 6 and a nut 7. The threaded rod 4 is fixedly installed on the outside of the case body 1, and the fixing plate 5 is slidably connected to the outside of the threaded rod 4. There are two fixing blocks 6, which are respectively arranged at both ends of the fixing plate 5. The nut 7 is threadedly connected to the outside of the threaded rod 4, and the two fixing blocks 6 are respectively slidably connected to the inside of the two fixing grooves 3. The two connecting mechanisms are Located between the two heat sinks 2, a fixing plate 5 is set to cooperate with the fixing groove 3. When the heat sink 2 is removed, the nut 7 is turned with a tool to release the threaded connection between the nut 7 and the threaded rod 4. At this time, the fixing plate 5 is pulled upward to release the connection between the fixing plate 5 and the fixing groove 3. At this time, the heat sink 2 can be removed from the outside of the box body 1. When installing, the two heat sinks 2 are placed on the outside of the box body 1. At this time, the fixing plate 5 is slid downward to allow the fixing block 6 to enter the inside of the fixing groove 3. At this time, the nut 7 is turned to make the nut 7 fit with the fixing plate 5. At this time, the fixing plate 5 is fixed, and the heat sink 2 is installed. The disassembly and assembly process of the heat sink 2 is simple, which is convenient for the staff to regularly clean or replace the heat sink 2, reducing the difficulty of work.

[0026] Each heat sink 2 has two circular holes 8 on its outside, and each circular hole 8 has a fixing screw 9 movably connected thereto. Two threaded grooves 10 are provided at both ends of the housing 1, and the fixing screws 9 are threadedly connected to the inside of the threaded grooves 10, so as to strengthen the installation of the heat sink 2.

[0027] Both ends of each fixed plate 5 are provided with a slide groove 11, and the fixed block 6 is slidably connected to the inside of the slide groove 11 to facilitate the adjustment of the position of the fixed block 6. A support shaft 12 is fixedly installed inside each slide groove 11, and an opening 13 is provided on the outside of each fixed block 6. The fixed block 6 is slidably connected to the outside of the support shaft 12 through the opening 13 to avoid the connection between the fixed block 6 and the slide groove 11 being released. A movable groove 14 is provided on the upper surface of each fixed plate 5, and a protrusion 15 is slidably connected to the inside of each movable groove 14, and the protrusion 15 is fixedly installed It is installed on the outside of the fixed block 6 to facilitate pulling the fixed block 6. By setting the slide groove 11 and cooperating with the protrusion 15, before the fixed block 6 enters the interior of the fixed groove 3, the staff pushes the protrusion 15 so that the protrusion 15 drives the fixed block 6 to move until the fixed block 6 moves to the fixed groove 3. At this time, the fixing plate 5 is pressed downward to make the fixed block 6 enter the interior of the fixed groove 3. The positions of the two fixed blocks 6 are adjusted according to the distance between the two fixed grooves 3 so that the two fixed blocks 6 can smoothly enter the interior of the fixed groove 3, thereby reducing the probability of re-grooving the heat sink 2.

[0028] Limiting blocks 16 are fixedly installed at both ends of the box body 1 , and the two limiting blocks 16 are respectively fitted with the two heat sinks 2 to facilitate limiting the positions of the heat sinks 2 .

[0029] Working principle:

[0030] The first step is to rotate the fixing screw 9 to release the connection between the fixing screw 9 and the threaded groove 10. At this time, use a tool to rotate the nut 7 to release the threaded connection between the nut 7 and the threaded rod 4. At this time, pull the fixing plate 5 upward to release the connection between the fixing plate 5 and the fixing groove 3. At this time, the heat sink 2 can be removed from the outside of the box body 1, and the heat sink 2 can be cleaned;

[0031] In the second step, after cleaning, the heat sink 2 is placed in contact with the limit block 16. By setting the slide groove 11 and cooperating with the protrusion 15, before the fixed block 6 enters the interior of the fixed groove 3, the staff pushes the protrusion 15 so that the protrusion 15 drives the fixed block 6 to move until the fixed block 6 moves to the fixed groove 3. At this time, the fixing plate 5 is pressed downward to make the fixed block 6 enter the interior of the fixed groove 3. The positions of the two fixing blocks 6 are adjusted according to the distance between the two fixing grooves 3 so that the two fixing blocks 6 can smoothly enter the interior of the fixing groove 3, reducing the probability of re-grooving the heat sink 2. At this time, the nut 7 is turned to make the nut 7 fit with the fixing plate 5. At this time, the fixing screw 9 is turned to connect the fixing screw 9 with the threaded groove 10. At this time, the heat sink 2 is installed.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
