Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0027] Embodiment
[0028] See Figures 1-3 as shown:
[0029] The utility model provides a high-temperature protection sleeve for a mechanical travel switch, comprising: a travel switch A to be protected and a heat insulation cover; the heat insulation cover is wrapped on a control component a3 of the travel switch A to be protected, for preventing the ambient temperature from being transmitted to the control component a3, and a detachable connection is formed between the heat insulation cover and a flat plate a2 for fixing the control component a3.
[0030] During specific implementation, the heat insulation cover is made of a soft and easily moldable material with good heat insulation effect. This can not only be wrapped outside the control component a3 to prevent the ambient temperature from being transmitted to the control component a3, achieving a good heat insulation effect. Additionally, the detachable connection makes its installation simpler and also facilitates the installation by later operators.
[0031] The heat insulation cover includes a molded part and a connecting part; the molded part is set in an open shape and is fitted to the outer surface of the control component a3; the connecting part is used to enclose the open mouth of the molded part to form a cover body and fix the heat insulation part on the flat plate a2.
[0032] The molded part is set as a wrapping piece that can cover the exposed outer surface of the control component a3. The wrapping piece is divided into a tail baffle 11, a top baffle 12, a first side baffle 13, and a second side baffle 14 according to the part that covers the outer surface of the control component a3.
[0033] During specific use, the tail baffle 11 is used to cover the tail end of the control component a3; the top baffle 12 is used to cover the top of the control component a3; the first side baffle 13 and the second side baffle 14 are used to cover both sides and the front end of the control component a3; the connecting part is arranged on the tail baffle 11, the top baffle 12, the first side baffle 13, and the second side baffle 14. Since the control component a3 is provided with a cable connector a2.
[0034] Therefore, an avoidance hole 111 is provided on the molded part; the avoidance hole 111 is arranged on the tail baffle 11. During specific use, when the heat insulation cover is wrapped on the control component a3, the cable connector a2 is passed out along the avoidance hole 111, which not only makes the heat insulation cover fit more closely to the control component a3 but also does not affect the use of the control component a3 itself.
[0035] The connecting part mainly consists of a first sewing connecting piece 112, a second sewing connecting piece 113, a hook-and-loop fastener rough side 15, a hook-and-loop fastener hook side 16, a first fixing strip 21, and a second fixing strip 22.
[0036] Both the first sewing connecting piece 112 and the second sewing connecting piece 113 are set as right-angled connecting strips.
[0037] The first stitching connecting piece 112 is connected to both the side edge of the tail baffle 11 and one end of the first side baffle 13, and is used to stitch the side edge of the tail baffle 11 and one end of the first side baffle 13 together.
[0038] The second stitching connecting piece 113 is connected to the other side edge of the tail baffle 11 and one end of the second side baffle 14, and is used to stitch the other side edge of the tail baffle 11 and one end of the second side baffle 14 together.
[0039] Through such a setting, the tail baffle 11, the first side baffle 13 and the second side baffle 14 jointly enclose one end of the heat shield.
[0040] In specific applications, the loop side 15 of the Velcro is arranged at the other end of the second side baffle 14; the hook side 16 of the Velcro is arranged at the other end of the first side baffle 13, and the loop side 15 of the Velcro forms a connection with the hook side 16 of the Velcro.
[0041] Through such a setting, the second side baffle 14 and the first side baffle 13 enclose the other end of the heat shield.
[0042] Since the switch rotating rod a4 is vertically connected to one end at the top of the control component a3, the lengths of the first side baffle 13 and the second side baffle 14 are set to be the same and exceed the length of the side of the control component a3, and the length of the top baffle 12 is less than the length of the first side baffle 13. Therefore, after the second side baffle 14 and the first side baffle 13 enclose the other end of the heat shield, a space for avoiding the switch rotating rod a4 can be reserved at the top of the heat shield, without affecting the daily use of the entire switch.
[0043] Both the first fixing strip 21 and the second fixing strip 22 are pasted on the flat plate a2 and are respectively located on both sides of the control component a3. By means of pasting, it is not only easy to fix the first fixing strip 21 and the second fixing strip 22 on the flat plate a2, but also convenient for later replacement and daily installation operation.
[0044] The first side baffle 13 is provided with a first side fixing piece 131, and the first side fixing piece 131 forms a fitting connection with the first fixing strip 21; the second side baffle 14 is provided with a second side fixing piece 141; and the second side fixing piece 141 forms a fitting connection with the second fixing strip 22.
[0045] In actual use, the first side fixing piece 131 and the first fixing strip 21 are set as a Velcro structure that is easy to disassemble, so as to facilitate disassembly and installation.
[0046] It should be noted that if there are directional indications involved in the embodiments of the present utility model, such as up, down, left, right, front, back..., the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture as shown in the drawings.
