Description

Technical Field

[0001] The present invention relates to the technical field of temperature detection, and in particular to a temperature detection tool. Background Art

[0002] A large number of fire alarm temperature sensors need to be installed on ships to detect the temperature in the cabin to avoid failure to detect fire in time. During daily maintenance, each fire alarm temperature sensor needs to be tested to determine its sensitivity or detect whether it is damaged or invalid.

[0003] Detection holes are distributed in the walls or cabinets of the cabin, and the fire alarm temperature sensor is set in the detection hole. When testing the fire alarm temperature sensor, the test tool is heated and inserted into the detection hole to transfer heat to the fire alarm temperature sensor, so as to detect the sensitivity of the fire alarm temperature sensor or whether it is damaged and invalid.

[0004] The current cup-type test tool has a high cost. When heated, the outer cover is heated as a whole, the heating speed is slow, and the test tool is large and inconvenient to carry. On-site operators usually use a small "slotted" screwdriver, heat it red, and then insert it into the detection hole for testing, which can easily burn the fire alarm temperature sensor and the operator. Summary of the invention

[0005] The invention provides a temperature detection tool, which is portable, has a fast heating speed and will not burn a fire alarm temperature sensor and an operator.

[0006] According to one aspect of the present invention, there is provided a temperature detection tool for installation on an electric heating rod, wherein the electric heating rod comprises a handle and an electric heating rod body arranged on the handle, wherein the temperature detection tool comprises:

[0007] The functional frame has a first end along the length direction for passing through a detection hole of the device to be detected and plugged into the inside of the device to be detected;

[0008] The installation limit joint is fixedly arranged at the second end of the functional frame along the length direction, and the electric heating rod body can be inserted into the functional frame so that the handle part is inserted into the installation limit joint.

[0009] Optionally, the installation limit joint comprises a first joint portion and a second joint portion connected to each other, the second joint portion forms a limit surface, and the limit surface is located at the connection between the first joint portion and the second joint portion;

[0010] The handle includes a first handle portion and a second handle portion, and both ends of the first handle portion are respectively connected to the electric heating rod body and the second handle portion. When the electric heating rod body is inserted into the functional frame, the first handle portion is inserted into the first joint portion, and the second handle portion is partially inserted into the second joint portion and abuts against the limiting surface along the insertion direction.

[0011] Optionally, along the length direction of the functional frame, the first joint portion is located inside the functional frame, and the second joint portion is located outside the functional frame.

[0012] Optionally, along the length direction of the functional frame, the orthographic projection of the functional frame is located within the orthographic projection of the second joint portion.

[0013] Optionally, the functional frame is a rectangular parallelepiped frame, and the detection holes are correspondingly rectangular parallelepiped holes.

[0014] Optionally, the functional frame is a cylindrical frame, and the detection hole corresponds to a cylindrical hole.

[0015] Optionally, the first end of the functional frame along the length direction is arc-shaped.

[0016] Optionally, the first end of the functional frame along the length direction is triangular.

[0017] Optionally, an elastic cushion layer is provided on the inner peripheral wall of the installation limit joint.

[0018] Optionally, the elastic cushion layer is made of high temperature resistant elastic material.

[0019] The temperature detection tooling provided in the embodiment of the present invention sets a functional frame so that the first end along the length direction can pass through the detection hole of the device to be detected and be inserted into the interior of the device to be detected. When the electric heating rod body is inserted into the functional frame, it can be isolated from external objects through the functional frame. Therefore, when the functional frame is passed through the detection hole of the device to be detected and inserted into the interior of the device to be detected, the inner wall of the detection hole and the fire alarm temperature sensor to be detected will not be burned due to overheating of the electric heating rod body, and the heat dissipation efficiency of the electric heating rod can be guaranteed, thereby improving the detection efficiency of the fire alarm temperature sensor. By setting an installation limit joint to fix the electric heating rod, it can be avoided that the electric heating rod body is extended into the functional frame too long so that it extends out of the functional frame in the extension direction, and the isolation of the electric heating rod body and the fire alarm temperature sensor to be detected can be guaranteed.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0029] An embodiment of the present invention provides a temperature detection tool for being installed on an electric heating rod. Figure 1is a schematic diagram of the structure of an electric heating rod provided by an embodiment of the present invention, such as Figure 1 As shown, the electric heating rod 1 includes a handle 11 and an electric heating rod body 12 arranged on the handle. The handle 11 can be provided with a charging interface, such as a USB interface or a Type-C interface, and the electric heating rod body 12 can be charged and heated through the charging interface to increase its temperature.

[0030] Figure 2 is a schematic diagram of the structure of a temperature detection tool provided by an embodiment of the present invention, such as Figure 2 As shown, the temperature detection tooling 2 includes: a functional frame 21, the first end along the length direction is used to pass through the detection hole of the device to be detected and be inserted into the interior of the device to be detected; an installation limit joint 22, fixedly arranged at the second end of the functional frame 21 along the length direction, and the electric heating rod body 12 can be inserted into the functional frame 21 so that the handle 11 is partially inserted into the installation limit joint 22.

[0031] The device to be detected may be a wall of a cabin, a cabinet on the cabin, or other equipment on which a fire alarm temperature sensor may be installed, and this embodiment of the present invention does not specifically limit this. Figure 3 is a schematic diagram of a structure of a device to be detected provided by an embodiment of the present invention, such as Figure 3 As shown, a detection hole 31 can be provided in the device to be detected 3, and a fire alarm temperature sensor (not shown in the figure) can be provided inside the detection hole 31. For the detection device of the fire alarm temperature sensor, the above-mentioned temperature detection tooling 2 can be used for detection. Among them, the functional frame 21 can be a hollow structure with only edges, so that when the electric heating rod body 12 is inserted into the functional frame 21, it will not affect the heat dissipation of the electric heating rod body 12, and because the electric heating rod body 12 is inserted into the functional frame 21, it can be ensured that the electric heating rod body 12 will not directly contact the inner wall of the detection hole 31, and will not directly contact the fire alarm temperature sensor to be detected, and the electric heating rod body 12 can be isolated from the fire alarm temperature sensor and the inner wall of the detection hole 31, so that the inner wall of the detection hole 31 and the fire alarm temperature sensor to be detected will not be burned due to overheating of the electric heating rod body 12.

[0032] It can be understood that the electric heating rod body 12 is inserted into the functional frame 21, and one end of the electric heating rod body 12 used for detection along the length direction is also located in the electric heating rod body 12, so that when the functional frame 21 is inserted into the interior of the detection hole 31, the functional frame 21 will be in direct contact with the fire alarm temperature sensor, and the electric heating rod body 12 will not be in direct contact with the fire alarm temperature sensor, thereby being able to play the role of isolation protection.

[0033] The installation limit joint 22 can enable at least a portion of the handle 11 of the electric heating rod 1 to be inserted into the installation limit joint 22 when the electric heating rod body 12 is inserted into the functional frame 21, so that the installation limit joint 22 can fix the electric heating rod 1 by directly contacting the handle 11 of the electric heating rod 1, and can prevent the electric heating rod body 12 from extending too long into the functional frame 21 and extending outside the functional frame 21 in the extension direction, thereby ensuring the isolation of the electric heating rod body and the fire alarm temperature sensor to be detected.

[0034] The temperature detection tooling provided in the embodiment of the present invention sets a functional frame so that the first end along the length direction can pass through the detection hole of the device to be detected and be inserted into the interior of the device to be detected. In this way, when the electric heating rod body is inserted into the functional frame, it can be isolated from external objects through the functional frame. Therefore, when the functional frame is passed through the detection hole of the device to be detected and inserted into the interior of the device to be detected, the inner wall of the detection hole and the fire alarm temperature sensor to be detected will not be burned due to overheating of the electric heating rod body, and the heat dissipation efficiency of the electric heating rod can be guaranteed, thereby improving the detection efficiency of the fire alarm temperature sensor. By setting an installation limit joint to fix the electric heating rod, it can be avoided that the electric heating rod body is extended too long into the functional frame so that it extends outside the functional frame in the extension direction, and the isolation of the electric heating rod body and the fire alarm temperature sensor to be detected can be guaranteed.

[0035] Optional, reference Figure 2 The installation limit joint 22 includes a first joint portion 221 and a second joint portion 222 connected to each other, and the second joint portion 222 forms a limit surface A1, and the limit surface is located at the connection between the first joint portion 221 and the second joint portion 222; the handle 11 includes a first handle portion 111 and a second handle portion 112, and the two ends of the first handle portion 111 are respectively connected to the electric heating rod body 12 and the second handle portion 112. When the electric heating rod body 12 is inserted into the functional frame 21, the first handle portion 11 is inserted into the first joint portion 221, and the second handle portion 112 is partially inserted into the second joint portion 222 and abuts against the limit surface A1 along the insertion direction.

[0036] Specifically, in the electric heating rod 1, the first handle portion 111 can be the connecting portion between the electric heating rod body 12 and the second handle portion 112. Since the electric heating rod body 12 is slender and has a small diameter, and the second handle portion 112 is usually the grip portion of the operator and has a large diameter, the first handle portion 111 can be presented as a gradually changing diameter. Correspondingly, in the installation of the limit joint 22, a limit surface A1 can be formed between the first joint portion 221 and the second joint portion 222 based on the different diameters. When the electric heating rod body 12 is inserted into the functional frame 21, the limit surface A1 can play a blocking role for the second handle portion 112, thereby achieving a limiting role for the electric heating rod 1 as a whole, and can prevent the electric heating rod body 12 from extending too long into the functional frame 21 and causing it to extend in the extension direction to the outside of the functional frame 21, thereby ensuring the isolation of the electric heating rod body 12 from the fire alarm temperature sensor to be detected.

[0037] Optional, continue to refer to Figure 2 Along the length direction of the functional frame 21 , the first joint portion 221 is located inside the functional frame 21 , and the second joint portion 222 is located outside the functional frame 21 .

[0038] Specifically, since the edge of the functional frame 21 itself has a certain diameter, for example, assuming that the edge of the functional frame 21 is an iron wire, the iron wire has a certain diameter. Therefore, the first joint part 221 is located inside the functional frame 21, and the second joint part 222 is located outside the functional frame 21, so that the diameter of the first joint part 221 can be smaller than the diameter of the second joint part 222. At this time, the side of the first joint part 221 facing the second joint part 222 is the limiting surface A1. In addition, the first joint part 221 and the second joint part 222 also have a certain thickness, so that the inner diameter of the first joint part 221 is smaller than the inner diameter of the second joint part 222, which is conducive to achieving the limiting of the electric heating rod 1.

[0039] Optional, continue to refer to Figure 2 , along the length direction of the functional frame 21, the orthographic projection of the functional frame 21 is located within the orthographic projection of the second joint portion 222. In this way, the arrangement of the functional frame 21 and the second joint portion 222 can be adapted to the electric heating rod 1. At this time, the second joint portion 222 can be located outside the functional frame 21, or the side where the functional frame 21 and the second joint portion 222 are connected can have a connection structure that extends outwardly in a circumference, so that the diameter of the second joint portion 222 connected thereto is greater than the inner diameter of the functional frame 21, so that the second joint portion 222 can be adapted to the handle 11.

[0040] For example, in a feasible embodiment, the height H1 of the functional frame 21 along the length direction can be 45 mm, and the length D1 in the direction perpendicular to the height can be 9 mm, and the width D2 can be 8 mm. The total length H2 of the installation limit joint 22 can be 18 mm, wherein the length H3 of the first joint part 221 can be 14 mm, and the length H4 of the second joint part 222 can be 4 mm. The inner diameter R1 of the first joint part 221 can be 9 mm, and the inner diameter R2 of the second joint part 222 can be 12 mm.

[0041] Optional, combined with reference Figure 2 and Figure 3 , the functional frame 21 is a rectangular parallelepiped frame, and the detection hole 31 corresponds to a rectangular parallelepiped hole. In this way, the shape of the functional frame 21 is adapted to the shape of the detection hole 31, so that the functional frame 21 can be easily inserted into the detection hole 31. Among them, when the functional frame 21 is a rectangular parallelepiped frame, it can at least include four edges L1 at the first end and four edges L2 along the length direction of the side, so that the functional frame 21 presents a hollow structure. In addition, a fixing frame L3 perpendicular to and connected to the side edge can be set on the side of the functional frame 21 along the length direction, which can improve the stability of the functional frame 21.

[0042] or, Figure 4 is a schematic diagram of the structure of another temperature detection tool provided by an embodiment of the present invention, such as Figure 4 As shown, the functional frame 21 is a cylindrical frame, and the detection hole corresponds to a cylindrical hole (not shown in the figure). In this way, the shape of the functional frame 21 can also be adapted to the shape of the detection hole, so that the functional frame 21 can be inserted into the detection hole. Among them, when the functional frame 21 is a cylindrical frame, it can at least include a circular edge L4 at the first end and four edges L5 along the side in the length direction, so that the functional frame 21 presents a hollow structure. In addition, a fixing frame L6 surrounding the side and perpendicular to and connected to the side edges can be set on the side of the functional frame 21 along the length direction, so as to improve the stability of the functional frame.

[0043] Optional, continue to refer to Figure 2 When the functional frame 21 is a rectangular parallelepiped frame, the first end of the functional frame 21 along the length direction is arc-shaped (as shown in the figure, the shorter edge L11 of the first end is arc-shaped). This makes it easier for the functional frame 21 to be inserted into the detection hole 31.

[0044] or, Figure 5 is a schematic diagram of the structure of another temperature detection tool provided by an embodiment of the present invention, such as Figure 5As shown, when the functional frame 21 is a rectangular parallelepiped frame, the first end of the functional frame 21 along the length direction is triangular (as shown in the figure, the shorter edge L11 of the first end is triangular), which can also make it easier for the functional frame 21 to be inserted into the detection hole 31.

[0045] Alternatively, refer to Figure 4 When the functional frame 2 is a cylindrical frame, the first end of the functional frame 21 along the length direction is conical, so that the functional frame 21 can be more easily inserted into the detection hole.

[0046] Optionally, an elastic cushion layer (not shown) is provided on the inner peripheral wall of the installation limit joint 22. Since the surface of the handle 11 of the electric heating rod 1 is usually relatively smooth, the handle 11 of the electric heating rod 1 can be further tightened by the anti-slip effect of the elastic cushion layer to improve the limiting effect of the electric heating rod 1, and it can ensure that the friction between the handle 11 of the electric heating rod 1 and the installation limit joint 22 is large and will not fall off, thereby preventing the operator from being injured due to the falling off.

[0047] The elastic cushion layer is made of a high temperature resistant elastic material, so that the elastic cushion layer can be prevented from being damaged by high temperature when in contact with the electric heating rod body 12 .

[0048] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
