DETAILED DESCRIPTION
[0028] The preferred embodiments of the utility model are described in detail below with reference to the drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, and the protection scope of the utility model can be more clearly and explicitly defined.
[0029] As Figures 1-10 The embodiment shows a steam pipe outer sleeve structure, which is sleeved on the outer side of the steam pipe to protect the steam pipe. The outer sleeve structure comprises at least one outer sleeve unit. The outer sleeve unit comprises a first arc-shaped member 1 and a second arc-shaped member 2. The inner diameter of the first arc-shaped member 1 is matched with the outer diameter of the steam pipe. The first arc-shaped member 1 has two axial ends, and an arc-shaped space 11 is formed in the first arc-shaped member 1 along the circumferential direction. One end of the arc-shaped space 11 is open in the circumferential direction, and both ends of the arc-shaped space 11 are open in the axial direction. The second arc-shaped member 2 has two axial ends. The second arc-shaped member 2 is inserted into the arc-shaped space 11 and can slide along the circumferential direction of the arc-shaped space 11, so as to freely enter and exit the arc-shaped space 11. The second arc-shaped member 2 slides along the circumferential direction of the arc-shaped space 11, has a sleeving position where the second arc-shaped member 2 extends out of the arc-shaped space 11 and covers the open side of the first arc-shaped member 1, and has a storage position where the second arc-shaped member 2 is hidden in the arc-shaped space 11. In the sleeving position, a sleeving space is formed between the first arc-shaped member 1 and the second arc-shaped member 2, so that the first arc-shaped member 1 and the second arc-shaped member 2 can be sleeved on the steam pipe through the sleeving space. The two axial ends of the second arc-shaped member 2 are exposed to the first arc-shaped member 1, and elastic arms 21 are formed on the two axial ends. The elastic arms 21 are strip structures extending along the axial direction of the second arc-shaped member 2, one end of each elastic arm 21 is fixed to the second arc-shaped member 2, and the other end of each elastic arm 21 forms an elastic end, so that the elastic end can move back and forth between the inner and outer directions of the second arc-shaped member 2. A stop protrusion 22 is formed on the outer wall of the elastic end of each elastic arm 21. Through the back and forth movement of the elastic arms 21, the stop protrusions 22 can be moved synchronously.
[0030] In the embodiment, when the outer sleeve unit is in the sleeving position, the two groups of outer sleeve units have a butt joint state in which the two groups of outer sleeve units are butt jointed along the axial direction. In the butt joint state, one end of the second arc-shaped member 2 of the outer sleeve unit on the first side is inserted into the arc-shaped space 11 of the outer sleeve unit on the second side, and the corresponding elastic arm 21 and stop protrusion 22 are deformed and synchronously extended into the arc-shaped space 11, and the stop protrusion 22 is clamped into the clamping hole 15. Through the above structure design, the stop protrusion 22 is limited and matched with the clamping hole 15, so as to limit the mutual separation of the two groups of outer sleeve units, the second arc-shaped member 2 is inserted into the arc-shaped space 11, so as to improve the stability of the connection between the two groups of outer sleeve units. When the elastic arm 21 is pressed down, the stop protrusion 22 is separated from the clamping hole 15, so as to separate the two groups of outer sleeve units from each other.
[0031] In the specific structural design, the outer wall of the first arc-shaped piece 1 is processed with a guide groove 14 extending along the circumference thereof. The guide groove 14 is communicated with the arc-shaped space 11, and the two ends of the guide groove 14 are closed. The second arc-shaped piece 2 is provided with a guide piece 23. The guide piece 23 is movably inserted into the guide groove 14. When the second arc-shaped piece 2 moves, the guide piece 23 moves in the guide groove 14 to play a guiding role. The guide piece 23 is threadedly connected to the second arc-shaped piece 2 to facilitate installation.
[0032] In the embodiment, in the specific structural design, the first arc-shaped piece 1 is a circular arc greater than one-half of the circumference. The second arc-shaped piece 2 is a circular arc less than one-half of the circumference. Through the structural design, the second arc-shaped piece 2 can be fully inserted into the arc-shaped space 11.
[0033] In the embodiment, in order to smoothly insert the elastic arm 21 and the stop protrusion 22 into the arc-shaped space 11, the stop protrusion 22 facing the head and tail ends of the second arc-shaped piece 2 is processed into an inclined surface, and the position of the stop protrusion 22 away from the inclined surface is processed into a vertical surface, which is limited and matched with the bayonet 15. In the aforementioned butt joint state, one end of the first arc-shaped piece 1 of each of the two sets of sleeve units is abutted to each other to improve the sealing performance when being combined.
[0034] The inner wall of the first arc-shaped piece 1 is provided with a first functional layer 12, and the inner wall of the second arc-shaped piece 2 is provided with a second functional layer 24. The first functional layer 12 and the second functional layer 24 can be rubber buffer layers to play a buffering role. Meanwhile, the first functional layer 12 and the second functional layer 24 can be heat preservation layers to be able to play a heat preservation role on the steam pipeline. The heat preservation layer is a conventional component of the prior art. The inner wall of the second arc-shaped piece 2 is also provided with a heat preservation layer. It should be noted that when the second arc-shaped piece 2 and the first arc-shaped piece 1 are sleeved on the steam pipeline, the first functional layer 12 and the second functional layer 24 are not in close contact with the steam pipeline, but have a certain gap space.
[0035] One end of the circumference of the first arc-shaped piece 1 is fixed with a first ear plate 13, and one end of the circumference of the second arc-shaped piece 2 is fixed with a second ear plate 25. When the second arc-shaped piece 2 moves to the sleeving position, one end of the circumference of the second arc-shaped piece 2 and one end of the circumference of the first arc-shaped piece 1 are abutted to each other, and the first ear plate 13 and the second ear plate 25 are locked and fixed by the threaded bolt 3 penetrating therebetween to lock and fix the first arc-shaped piece 1 and the second arc-shaped piece 2 to each other. In the embodiment, one of the first ear plate 13 and the second ear plate 25 is processed with a through hole for the threaded bolt 3 to penetrate, and the other is processed with a threaded hole for the threaded bolt 3 to be threadedly connected.
[0036] In specific use, the first arc-shaped member 1 is placed on one side of the steam pipe, the second arc-shaped member 2 is removed from the arc-shaped space 11 to the sleeving position, so that the steam pipe is wrapped between the first arc-shaped member 1 and the second arc-shaped member 2, the first lug plate 13 and the second lug plate 25 are locked by the bolt 3, so as to lock and fix the first arc-shaped member 1 and the second arc-shaped member 2. A plurality of groups of sleeve units are sequentially sleeved on the steam pipe, the two adjacent groups of sleeve units are axially inserted into each other, so that the second arc-shaped plate is inserted into the corresponding arc-shaped space 11, and the stop protrusion 22 is clamped into the clamping opening 15, so as to complete the combined docking. The stop protrusion 22 is separated from the clamping opening 15 by pressing the elastic arm 21, and the two adjacent groups of sleeve units are pushed away from each other. The bolt 3 is disassembled, and the second arc-shaped member 2 is pushed into the arc-shaped space 11, so as to disassemble the sleeve unit from the steam pipe. In the above mode, the local sleeve unit can be replaced, and the disassembly and assembly are convenient, time-saving and labor-saving, and the sleeve units can be combined for use, so as to form sleeve structures of different lengths, effectively adapt to the actual application requirements of steam pipes of different lengths.
[0037] The above is only an embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
