Description

Technical Field

[0001] The present application relates to the technical field of copper filters, and in particular to a copper filter that is easy to disassemble, assemble and replace. Background Art

[0002] The copper filter is also called a drying filter. It is filled with activated alumina, anhydrous calcium chloride or silica gel to absorb moisture in the refrigerant. Filters are installed at both ends of the liquid inlet and outlet of the drying filter to remove mechanical impurities in the refrigeration system and prevent blockage.

[0003] The two ends of the traditional copper filter are fixed to the copper tube by welding. Although the sealing performance is high, it is inconvenient to disassemble, which is not conducive to the maintenance or replacement of the copper filter in the later stage. There are some detachable copper filters. For example, the Chinese utility model patent with application number CN201922441319.9 discloses a copper filter that is easy to disassemble and replace. This scheme drives the clamp to move through a threaded rod and a bevel gear, so that the clamp squeezes the two ends of the copper filter and connects and fixes them to the copper tube.

[0004] However, the above scheme still has shortcomings. The above scheme uses multiple threaded rods, bevel gears, bearings and other components, which increases the difficulty of producing the copper filter. In addition, multiple components need to be accurately connected and meshed, which increases the difficulty of assembly and is inconvenient. Utility Model Content

[0021] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0022] The present application embodiment discloses a copper filter that is easy to disassemble and replace. Figure 1-Figure 3 A copper filter that is easy to disassemble, assemble and replace comprises a copper filter body 1, and connecting copper tubes 2 are fixed at both ends of the copper filter body 1; a No. 2 mounting sleeve 10 is fixed at the end of the connecting copper tube 2, and a plurality of arc-shaped embedded plates 12 distributed in a circumferential direction are fixed on the No. 2 mounting sleeve 10, and a plurality of arc-shaped embedded plates 12 are provided with clamping grooves 13; it also comprises an extended copper tube 3 and a positioning mechanism, and two extended copper tubes 3 are respectively located at both ends of the copper filter body 1, and a No. 1 mounting sleeve 4 is fixed at one end of the extended copper tube 3, and a plurality of arc-shaped clamping grooves 5 distributed in a circumferential direction are provided on the No. 1 mounting sleeve 4, and the arc-shaped clamping grooves 5 are adapted to the arc-shaped embedded plates 12; the positioning mechanism is installed on the connecting copper tube 2, and is used to connect and fix the extended copper tube 3 and the connecting copper tube 2.

[0023] The positioning mechanism includes a sliding sleeve 8 sleeved on the connecting copper tube 2, and a pushing spring 14 sleeved on the connecting copper tube 2. A fixed sleeve 9 is fixed on the connecting copper tube 2. The pushing spring 14 is respectively connected to the sliding sleeve 8 and the fixed sleeve 9. The sliding sleeve 8 is slidably connected to the connecting copper tube 2. A plurality of insertion holes 7 are opened on the No. 1 mounting sleeve 4. A plurality of insertion rods 11 are fixed on the sliding sleeve 8. The insertion rods 11 are adapted to the insertion holes 7.

[0024] During installation, align the No. 1 installation sleeve 4 with the No. 2 installation sleeve 10, so that the multiple arc-shaped embedded plates 12 pass through the arc-shaped slots 5 respectively, and then the staff rotates the arc-shaped embedded plates 12 in the direction of the slots 13 on the arc-shaped slots 5, so that the slots 13 are locked at one end of the arc-shaped slots 5, and then rotate the sliding sleeve 8 so that the arched hole 16 on it is sleeved on the arch block 17. At this time, multiple insertion rods 11 are aligned with the insertion holes 7 respectively. After loosening the sliding sleeve 8, the sliding sleeve 8 can continue to move due to the elastic thrust of the pushing spring 14, and finally the insertion rod 11 is inserted into the insertion hole 7, and then the connected copper tube 2 or the extended copper tube 3 cannot be rotated, and the installation and fixation are completed. The operation is simple and convenient.

[0025] In this embodiment, if Figure 2 and Figure 3 As shown, the end of the insertion rod 11 is provided with a chamfer, which can reduce the contact area of ​​the end of the insertion rod 11, so that it can be inserted into the insertion hole 7 more smoothly, increasing the convenience of installation.

[0026] In this embodiment, if Figure 2 As shown, a sealing rubber ring 6 is fixed at one end of the extended copper tube 3, and a sealing groove 15 is opened at the end of the connecting copper tube 2. The sealing rubber ring 6 is embedded in the sealing groove 15. This arrangement can increase the connection sealing between the extended copper tube 3 and the connecting copper tube 2 to avoid leakage.

[0027] In this embodiment, if Figure 2 and Figure 3 As shown, a plurality of arc-shaped notches are provided on the edge of the sliding sleeve 8, and this arrangement makes it easy to screw and rotate the sliding sleeve 8, thus facilitating installation by workers.

[0028] In this embodiment, if Figure 2 and Figure 3 As shown, a pair of arched holes 16 are opened on the sliding sleeve 8, and a pair of arched blocks 17 are fixed on the connecting copper tube 2. The arched block 17 is connected to the second mounting sleeve 10, and the arched holes 16 are adapted to the arched blocks 17. When disassembling, the sliding sleeve 8 is horizontally moved away from the arched blocks 17, and then the sliding sleeve 8 is arbitrarily rotated to make the arched holes 16 deviate from the arched blocks 17, and then one side of the sliding sleeve 8 can be against the arched block 17, and then the staff can twist and separate the connecting copper tube 2 and the extended copper tube 3.

[0029] The implementation principle of the copper filter that is easy to disassemble, assemble and replace in the embodiment of the present application is as follows: during installation, align the No. 1 installation sleeve 4 with the No. 2 installation sleeve 10, so that the multiple arc-shaped embedded plates 12 pass through the arc-shaped slots 5 respectively, and then the staff rotates according to the direction of the slots 13 on the arc-shaped embedded plates 12, so that the slots 13 are locked at one end of the arc-shaped slots 5, and then rotate the sliding sleeve 8 so that the arched holes 16 on it are sleeved on the arched blocks 17. At this time, the multiple insertion rods 11 are aligned with the insertion holes 7 respectively, and after the sliding sleeve 8 is loosened, , due to the elastic thrust of the pushing spring 14, the sliding sleeve 8 can continue to move, and finally the insertion rod 11 is inserted into the insertion hole 7, and then the connected copper tube 2 or the extended copper tube 3 cannot be rotated, and the installation and fixation can be completed. The operation is simple and convenient. When disassembling, the sliding sleeve 8 is horizontally moved away from the arch block 17, and then the sliding sleeve 8 is arbitrarily rotated to make the arch hole 16 deviate from the arch block 17, and then one side of the sliding sleeve 8 can be against the arch block 17, and then the staff can twist and separate the connected copper tube 2 and the extended copper tube 3;

[0030] By arranging an extended copper tube 3, a No. 1 mounting sleeve 4, an arc-shaped slot 5, an insertion hole 7, a sliding sleeve 8, a fixed sleeve 9, a No. 2 mounting sleeve 10, an insertion rod 11, an arc-shaped embedded plate 12, a slot 13 and a pushing spring 14, the installation and fixation of the copper filter body 1 can be quickly achieved through a rotating snap-fit ​​installation, and the subsequent inspection and replacement of the copper filter body 1 is also facilitated, thereby improving convenience.
