DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] See also Figure 1-5 This embodiment provides the following technical solution: a graphite heat exchanger, comprising a heat exchanger body 1 and a fixing mechanism arranged on the side wall of the heat exchanger body 1. In some embodiments, a plurality of fixing mechanisms may be provided, and the plurality of fixing mechanisms may be distributed circumferentially on the side wall of the heat exchanger body 1, or may be distributed in a linear array on the side wall of the heat exchanger body 1.

[0026] The fixing mechanism includes a first mounting seat 2 and a second mounting seat 3, a baffle 4 is fixedly connected inside the first mounting seat 2, positioning plates 5 are fixedly arranged on the front and rear sides of the right end of the baffle 4, and positioning grooves 6 are arranged on the sides opposite to the positioning plates 5 on both sides; a driving frame is movably arranged on the second mounting seat 3, a driving mechanism 8 is connected to the right end of the driving frame, and a movable plate 9 is fixedly arranged on the other end of the driving frame, and the front and rear sides of the movable plate 9 are connected to the plug plate 11 through a connecting piece 10, and a positioning block 12 adapted to the positioning groove 6 is fixedly arranged on the plug plate 11. Through the driving mechanism 8, the movable plate 9 can drive the plug plates 11 on both sides to approach or move away from the movable plate 9 at the same time, so that the positioning blocks 12 on the left and right sides can be inserted into or detached from the inside of the positioning groove 6, which is convenient for disassembly and assembly of the heat exchanger body 1 and increases the installation efficiency of the user.

[0027] One end of the plug board 11 is rotatably connected to the pulley 13. In some embodiments, the pulley 13 is arranged at the left end of the plug board 11. Through the pulley 13, when the plug board 11 contacts the right wall of the baffle 4, the friction between the plug board 11 and the first mounting seat 2 can be reduced, which is conducive to the horizontal sliding of the plug board 11.

[0028] A guide groove 14 is also provided on the bottom wall of the first mounting seat 2, and a guide block 15 fixedly connected to the movable plate 9 is movably connected in the guide groove 14. The guide groove 14 and the guide block 15 facilitate sliding the movable plate 9 into the first mounting seat 2, thereby limiting the movable plate 9.

[0029] A slide groove 16 for the guide block 15 to slide is provided on the bottom wall of the second mounting seat 3. Through the slide groove 16, the movable plate 9 can enter the second mounting seat 3, avoiding the movable plate 9 being unable to slide into the second mounting seat 3 due to problems with the guide block 15.

[0030] The connecting member 10 includes a first connecting seat 101 fixedly arranged on the movable plate 9 and a second connecting seat 102 fixedly arranged on the plug plate 11. The first connecting seat 101 and the second connecting seat 102 are hingedly connected by a connecting rod 103. Through the connecting rod 103, when the movable plate 9 moves, the movable plate 9 can drive the plug plate 11 to move.

[0031] In some embodiments, after the pulley 13 contacts the right side wall of the baffle 4, the movable plate 9 continues to move toward the baffle 4. Under the action of the connecting rod 103, the plug plates 11 on the front and rear sides slide away from the movable plate 9 at the same time, making it easier for the positioning block 12 to be inserted into the positioning groove 6.

[0032] The driving mechanism 8 includes a threaded rod 81, a sliding rod 82 and a limiting rod 84. The threaded rod 81 is fixedly connected to one end of the sliding rod 82. The other ends of the threaded rod 81 and the sliding rod 82 are rotatably set on the second mounting seat 3. The threaded rod 81 passes through the threaded hole set on the driving plate 7 and is threadedly connected to the driving plate 7. A handle 83 is fixedly set on one end of the threaded rod 81. Through the threaded rod 81, the sliding rod 82 and the handle 83, the driving plate 7 can be threadedly connected to the threaded rod 81 or slidably connected to the sliding rod 82.

[0033] The limiting rod 84 is fixedly disposed on the second mounting seat 3 and is disposed parallel to the threaded rod 81 . The limiting rod 84 passes through a hole groove disposed on the driving plate 7 and is slidably connected to the driving plate 7 . The driving plate 7 can be limited by the limiting rod 84 .

[0034] In some embodiments, the threaded rod 81 is arranged at the left end of the second mounting base 3, and the sliding rod 82 is arranged at the right end of the second mounting base 3. When the driving plate 7 is threadedly connected to the threaded rod 81, the handle 83 can be rotated so that the driving plate 7 can drive the movable plate 9 to move left or right under the limiting action of the limiting rod 84. When the driving plate 7 is located on the sliding rod 82, under the limiting action of the limiting rod 84, the driving plate 7 can be pushed to slide horizontally to the left or right on the sliding rod 82.

[0035] The first mounting seat 2 and the second mounting seat 3 are both fixedly provided with a first fixing member 17. In some embodiments, the first fixing member 17 is a bolt, which can detachably connect the first mounting seat 2 to the heat exchanger body 1, or detachably connect the second mounting seat 3 to the wall, so as to install the heat exchanger body 1.

[0036] A reinforcing rib 18 is provided above the positioning plate 5, and both ends of the reinforcing rib 18 are fixedly connected to the positioning plate 5 and the second mounting seat 3 through a second fixing member 19 respectively. In some embodiments, the second fixing member 19 is also a bolt. The second fixing member 19 can facilitate the disassembly and assembly of the positioning plate 5 and increase the stability of the positioning plate 5.

[0037] The working principle of the utility model is as follows: when installation is required, the driving plate 7 is pushed to move the driving plate 7 along the slide bar 82 and the limit rod 84 toward the first mounting seat 2, and at the same time, the guide block 15 on the moving plate 9 is inserted into the guide groove 14 on the first mounting seat 2;

[0038] Until the driving plate 7 is pushed onto the threaded rod 81, the driving plate 7 is threadedly connected to the threaded rod 81, and then the handle 83 is turned to make the threaded rod 81 rotate and drive the driving plate 7 to drive the movable plate 9 to move toward the baffle 4, until the pulley 13 at the left end of the plug plate 11 contacts the baffle 4, and the handle 83 is continued to be turned to make the movable plate 9 continue to move toward the baffle 4. At this time, under the action of the connecting rod 103, the plug plates 11 on the front and rear sides simultaneously move in the direction away from the movable plate 9 until the positioning block 12 on the plug plate 11 is inserted into the positioning groove 6 on the positioning plate 5, thereby completing the fixation of the first mounting seat 2 and the second mounting seat 3, and completing the fixation of the heat exchanger body 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
