There is a small clearance fit between the partition and the housing, and sealing is achieved through a sealing ring. The sealing ring has a certain compression amount, which makes it difficult to disassemble and assemble the conduit and partition assembly in the housing after reaching the mating surface. It is very difficult to complete it by manpower alone. Therefore, it is very necessary to design a disassembly and assembly device for the conduit and partition assembly inside the housing with a simple structure, convenient operation, and low manufacturing cost. Content of the Utility Model

[0003] The purpose of the utility model is to provide an installation device and a disassembly device for a conduit and a partition assembly inside a housing, which are used to solve the technical problem of difficult disassembly and assembly of the conduit and partition assembly in the housing.

[0004] The utility model is realized by adopting the following technical scheme:

[0005] An installation device for a conduit and a partition assembly inside a housing includes a sleeve, a first baffle, and a second baffle. One end of the sleeve is provided with an internal thread. The sleeve is threadedly connected with a first pull rod. One end of the first pull rod is detachably connected with one end of a second pull rod. A first through hole is provided in the center of the first baffle, and a second through hole is provided in the center of the second baffle. The diameter of the first through hole is smaller than the outer diameter of the end of the sleeve with internal thread, and the diameter of the second through hole is smaller than the outer diameter of the other end of the second pull rod. The first baffle is sleeved on the first pull rod through the first through hole, and the second baffle is sleeved on the second pull rod through the second through hole.

[0006] During application, after the conduit and partition assembly are assembled, they are assembled into the housing. First, the conduit and partition assembly are pushed into the housing from right to left until they cannot be pushed by hand.

[0007] At this time, after the second baffle is sleeved on the second pull rod, the second pull rod is pushed into the conduit from right to left until the second baffle is stuck at one end of the conduit.

[0008] Then the first baffle is sleeved on the first pull rod, and the first pull rod is pushed into the conduit from left to right. After that, the first pull rod and the second pull rod are connected.

[0009] Finally, install the sleeve on the first pull rod through threads. After assembling a device for installing a conduit and a partition assembly inside a housing, rotate the sleeve, and the first pull rod will slowly move to the left. During the movement of the first pull rod, it will drive the second pull rod to slowly move to the left. The second baffle is stuck on the second pull rod. During the movement of the second pull rod, the second baffle pushes the conduit and the partition assembly to slowly move to the left until the sleeve cannot be rotated anymore, indicating that the conduit and the partition assembly are installed in place. Then disassemble the device for installing a conduit and a partition assembly inside a housing.

[0010] Further preferably, a through hole is provided at the other end of the sleeve, and a handle is assembled in the through hole. The handle is in the shape of a round rod, and the setting of the handle facilitates rotating the sleeve.

[0011] Further preferably, the wall thickness of the threaded part of the sleeve is greater than that of the non-threaded part. The increase in the wall thickness of the threaded part is to enhance the strength of the sleeve. The threaded part and the non-threaded part on the outer side of the sleeve are transitioned by a chamfer. The design of the chamfer transition is also to enhance the strength of the sleeve.

[0012] Further preferably, a plurality of through holes are provided on the first baffle. The setting of the plurality of through holes can reduce the weight of the first baffle.

[0013] Further preferably, a stepped circle for making the first baffle block on the conduit is provided on one side or both sides of the first baffle. The design of the stepped circle facilitates the first baffle to be stuck into the inner hole of the housing.

[0014] Further preferably, the detachable connection between the first pull rod and the second pull rod can be achieved in the following way: external threads are provided at both ends of the first pull rod, and the other end of the first pull rod is threadedly connected to the second pull rod. Internal threads are provided at one end of the second pull rod, and external threads are provided at the other end. A nut is screwed on the external thread end of the second pull rod.

[0015] Further preferably, the diameter of the threaded part at the other end of the first pull rod is smaller than that of the non-threaded part. This part has two functions. One is to facilitate distinguishing which end of the first pull rod is connected to the sleeve, and the other is to facilitate connecting to the second pull rod with the same diameter. If the thread diameters at both ends of the first pull rod are the same, it cannot be connected to the second pull rod with the same diameter.

[0016] Further preferably, the first pull rod and the second pull rod are connected by an extension rod. Internal threads are provided at both ends of the extension rod. Internal threads and external threads are provided at one end of the second pull rod at the same time. If the housing is too long, a device for installing a conduit and a partition assembly inside a housing can be used by adding an extension rod with a suitable length.

[0017] Further preferably, the second baffle is a retaining ring. A circular groove is provided inwardly on one side of the retaining ring. The outer diameter of the retaining ring is greater than the diameter of the conduit. The retaining ring is stuck on the conduit. When the second pull rod is driven by the first pull rod to move slowly, the retaining ring can drive the conduit and the partition assembly to move slowly in the same direction.

[0018] A device for disassembling a conduit and a partition assembly inside a housing, comprising a sleeve, a first baffle and a second baffle. An internal thread is provided at one end of the sleeve. The sleeve is threadedly connected with a first pull rod. One end of the first pull rod is detachably connected with one end of a second pull rod. A first through hole is provided at the center of the first baffle. A second through hole is provided at the center of the second baffle. The diameter of the first through hole is smaller than the outer diameter of the end of the sleeve with the internal thread. The diameter of the second through hole is smaller than the outer diameter of the other end of the second pull rod. The first baffle is sleeved on the first pull rod through the first through hole. The second baffle is sleeved on the second pull rod through the second through hole.

[0019] During application, first, the second baffle is sleeved on the second pull rod, and then the second pull rod is pushed into the conduit from left to right until the second baffle is stuck on the conduit.

[0020] Then, the first baffle is sleeved on the first pull rod, and the first pull rod is pushed into the conduit from right to left. After that, the first pull rod and the second pull rod are connected.

[0021] Finally, the sleeve is threadedly installed on the first pull rod. After assembling a device for disassembling a conduit and a partition assembly inside a housing, rotate the sleeve. The first pull rod will move slowly to the right. During the movement of the first pull rod, it will drive the second pull rod to move slowly to the right. The second baffle is stuck on the second pull rod. During the movement of the second pull rod, the second baffle pushes the conduit and the partition assembly to move slowly to the right until it indicates that the conduit and the partition assembly are installed in place when the sleeve cannot be rotated anymore. After that, disassemble the device for disassembling a conduit and a partition assembly inside a housing.

[0022] Further preferably, a through hole is provided at the other end of the sleeve. A handle is assembled in the through hole. The handle is in the shape of a round rod. The setting of the handle facilitates the rotation of the sleeve.

[0023] Further preferably, the wall thickness of the threaded part of the sleeve is greater than the wall thickness of the part without the thread. The increase in the wall thickness of the threaded part is to enhance the strength of the sleeve. The threaded part and the part without the thread on the outer side of the sleeve are transitioned through a chamfer. The design of the chamfer transition is also to enhance the strength of the sleeve.

[0024] Further preferably, a plurality of through holes are provided on the first baffle. The setting of the plurality of through holes can reduce the weight of the baffle.

[0025] Further preferably, a stepped circle for making the first baffle block on the conduit is provided on one side or both sides of the first baffle. The design of the stepped circle facilitates the first baffle to be inserted into the inner hole of the housing.

[0026] Further preferably, the detachable connection between the first pull rod and the second pull rod can be achieved in the following way: external threads are provided at both ends of the first pull rod, the other end of the first pull rod is threadedly connected to the second pull rod, internal threads are provided at one end of the second pull rod, and external threads are provided at the other end. A nut is screwed onto the external thread end of the second pull rod.

[0027] Further preferably, the diameter of the threaded part at the other end of the first pull rod is smaller than that of the unthreaded part. This design has two functions. One is to facilitate distinguishing which end of the first pull rod is connected to the sleeve, and the other is to facilitate connection with the second pull rod of the same diameter. If the thread diameters at both ends of the first pull rod are the same, it will be impossible to connect with the second pull rod of the same diameter.

[0028] Further preferably, the first pull rod and the second pull rod are connected by an extension rod. Internal threads are provided at both ends of the extension rod. Internal threads and external threads are provided at one end of the second pull rod at the same time. If the shell is too long, a shell internal conduit and partition assembly disassembly device can be used by adding an extension rod with a suitable length.

A through hole 21 is provided at the center of the first baffle 2, and a through hole is provided at the center of the second baffle. The diameter of the through hole 21 is smaller than the outer diameter of the threaded end of the sleeve 1, and the diameter of the through hole is smaller than the outer diameter of the other end of the second pull rod 5. The first baffle 2 is sleeved on the first pull rod 4 through the through hole 21, and the second baffle is sleeved on the second pull rod 5 through the through hole.

[0052] The other end of the sleeve 1 is provided with a through hole, and a handle 7 is assembled in the through hole. The handle 7 is in the shape of a round rod. The wall thickness of the threaded part of the sleeve 1 is greater than the wall thickness of the non-threaded part. The threaded part and the non-threaded part on the outer side of the sleeve 1 are transitioned through a chamfer.

[0053] The first baffle 2 is provided with a plurality of through holes, and a stepped circle for blocking the first baffle 2 on the conduit 103 is provided on one side or both sides of the first baffle 2.

[0054] As Figure 3As shown in the figure, external threads are provided at both ends of the first pull rod 4. The other end of the first pull rod 4 is threadedly connected to a second pull rod 5. One end of the second pull rod 5 is provided with an internal thread, and the other end is provided with an external thread. A nut 8 is screwed onto the external thread end of the second pull rod 5. In this embodiment, the standard of the nut 8 is M16 GB / T6170-2015, and a washer 81 is also provided in front of the nut 8, with the standard of 16 GB / T97.1-2002.

[0055] The diameter of the threaded part at the other end of the first pull rod 4 is smaller than that of the non-threaded part. The first pull rod 4 and the second pull rod 5 are connected by an extension rod 6. Both ends of the extension rod 6 are provided with internal threads. One end of the second pull rod 5 is provided with both an internal thread and an external thread at the same time. The thread directions of all the above-mentioned threads are kept consistent.

[0056] As Figure 4 shown, the second baffle is a retaining ring 31. A circular groove 32 is provided inward on one side of the retaining ring 31. The outer diameter of the retaining ring 31 is larger than the diameter of the conduit 103.

[0057] The working principle is as follows: As Figures 5-6 shown, after the conduit and partition assembly 10 is assembled, it is assembled into the housing 9. First, the conduit and partition assembly 10 is pushed into the housing 9 from right to left until it cannot be pushed any further (due to the obstruction of the sealing ring 102), that is, when the front, middle, and rear partitions 101 all enter their respective housing 9 assembly surfaces, stop manually pushing the conduit and partition assembly 10.

[0058] At this time, connect the first pull rod 4, the extension rod 6, and the second pull rod 5 in sequence, then pass through the inner hole of the conduit 103 (pay attention to the direction), then sleeve the first baffle 2 onto the left end of the first pull rod 4, so that the right end stop (step circle) of the first baffle 2 is closely attached to the inner stop at the left end of the housing 9. Install the sleeve 1 and the handle 7 in sequence. Then, at the right end of the housing 9, sleeve the retaining ring 31 onto the second pull rod 5, and then install the washer 81 and the nut 8 respectively, so that the left end face of the retaining ring 31 is in contact with the right end face of the fixing nut 104 on the conduit 103, and tighten the nut 8. In this way, the installation of the conduit and partition assembly installation device on the housing 9 is completed.

[0059] After the conduit and partition assembly installation device is installed on the housing 9, rotate the handle 7 clockwise. The pulling force is transmitted to the retaining ring 31 through the sleeve 1, the first pull rod 4, the extension rod 6, and the second pull rod 5. Under the action of the retaining ring 31, the conduit and partition assembly 10 slowly moves to the left side of the housing 9. Continue to rotate the handle 7 until the left end face of the rear partition 101 is closely attached to the right end face 91 of the corresponding stop in the housing 9 (specifically, when the handle 7 cannot be rotated). At this time, the conduit and partition assembly 10 is installed in place, and then the conduit and partition assembly installation device inside one housing is removed one by one.

[0060] Embodiment 2. A device for disassembling the internal conduit and partition assembly of a housing, comprising a sleeve 1, a first baffle 2 and a second baffle. One end of the sleeve 1 is provided with an internal thread, and the sleeve 1 is threadedly connected to one end of a first pull rod 4. The first pull rod 4 is detachably connected to one end of a second pull rod 5. A through hole 21 is provided at the center of the first baffle 2, and a through hole is provided at the center of the second baffle. The diameter of the through hole 21 is smaller than the outer diameter of the threaded end of the sleeve 1, and the diameter of the through hole of the second baffle is smaller than the outer diameter of the other end of the second pull rod 5. The first baffle 2 is sleeved on the first pull rod 4 through the through hole 21, and the second baffle is sleeved on the second pull rod 5 through the through hole. The thread directions of the threads are all the same.

[0061] A through hole is provided at the other end of the sleeve 1, and a handle 7 is assembled in the through hole. The handle 7 is in the shape of a round rod.

[0062] The wall thickness of the threaded part of the sleeve 1 is greater than that of the non-threaded part. The threaded part and the non-threaded part on the outer side of the sleeve 1 are transitioned by a chamfer.

[0063] The first baffle 2 is provided with a plurality of through holes, and a stepped circle for blocking the first baffle 2 on the conduit 103 is provided on one side or both sides of the first baffle 2.

[0064] External threads are provided at both ends of the first pull rod 4. The other end of the first pull rod 4 is threadedly connected to the second pull rod 5. One end of the second pull rod 5 is provided with an internal thread, and the other end is provided with an external thread. A nut 8 is screwed on the external thread end of the second pull rod 5.

[0065] The diameter of the threaded part at the other end of the first pull rod 4 is smaller than that of the non-threaded part.

[0066] The first pull rod 4 and the second pull rod 5 are connected by an extension rod 6. Internal threads are provided at both ends of the extension rod 6, and one end of the second pull rod 5 is provided with both an internal thread and an external thread at the same time.

[0067] As Figures 7-8 shown, the second baffle is a retaining ring 33, and a plurality of stepped circles are provided on one side of the retaining ring 33.

[0068] Markings are provided on the first baffle 2 to facilitate the operator to quickly select the appropriate size of the first baffle 2.

[0069] The working principle is as follows: As Figures 9-10 shown, before disassembling the conduit and partition assembly 10, a device for disassembling the internal conduit and partition assembly of a housing should be installed in the housing 9 first. First, the first pull rod 4 and the extension rod 6 are connected by threads and passed through the inner hole of the conduit 103. The direction is as Figure 8As shown in the figure, then assemble the retaining ring 33, washer 81 and nut 8 in sequence at the left end of the second pull rod 5, so that the front end stop (step circle) of the retaining ring 33 enters the inner hole of the conduit 103, and the right end face of the retaining ring 33 fits with the left end face of the conduit 103; then sleeve the first baffle 2 onto the right end of the first pull rod 4, and successively install the sleeve 1 and the handle 7. Rotate the handle 7 clockwise so that the left end face of the first baffle 2 contacts the maximum diameter part of the right end face of the housing 9. Rotate the handle 7 to tighten the whole device, and complete the installation of a disassembly device for the conduit and partition plate assembly inside the housing.

[0070] After a disassembly device for the conduit and partition plate assembly inside the housing is installed on the housing 9, rotate the handle 7 of the device clockwise, and transmit the pulling force to the retaining ring 33 through the sleeve 1, the first pull rod 4, the extension rod 6 and the second pull rod 5. Under the action of the retaining ring 33, the conduit and partition plate assembly 10 slowly moves to the right end of the housing 9. Continue to rotate the handle 7 of the device until the left end face of the rear partition plate 101 disengages from the corresponding stop of the housing 9 (that is, the rear partition plate 101 disengages from the mating surface 92 of the housing 9. In this embodiment, each partition plate of the conduit and partition plate assembly 10 enters and disengages from the mating surface 92 of the housing 9). At this time, remove the left end nut 8, washer 81 and retaining ring 33, pull out the remaining parts of a disassembly device for the conduit and partition plate assembly inside the housing from the housing 9, and then pull out the conduit and partition plate assembly 10 from the housing 9 to complete the disassembly work of the conduit and partition plate assembly 10.

[0071] The present utility model is designed on the basis of fully considering the structures of the housing 9, the conduit and partition plate assembly 10 and their assembly relationships. Using the lever principle, a first baffle 2 with a circular stop is supported at the left end (for "installation" operation) or the right end (for "disassembly" operation) of the housing 9. Taking advantage of the fact that the conduit 103 is located in the center of the housing 9 and the center of the conduit 103 is a through hole, a pull rod combination is designed in the middle, passing through the central hole of the conduit 103, and a pressing ring 31 (for "installation" operation) or a retaining ring 33 (for "disassembly" operation) is designed at the other end to support on the right end face (for "installation" operation) or the left end face (for "disassembly" operation) of the conduit 103 respectively to complete the assembly or disassembly of the conduit and partition plate assembly 10. The first baffle 2 and the second baffle of the present utility model are both made of bakelite, which is both light and can protect the housing 9, etc. from being damaged; each pull rod, handle 7, etc. are all made of stainless steel material, which can effectively prevent rust and corrosion; the present utility model is ingeniously designed, simple, convenient to process, low in cost, convenient to operate, time-saving and labor-saving.

[0072] The above are only specific embodiments of the present utility model, enabling those skilled in the art to understand or implement the present utility model. Although detailed descriptions have been made with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
