A fixing mechanism is provided on the rear side of the mounting cover. The utility model has a simple structure and a clever design. It is easy for people to carry with them. It does not require additional power supply. Staff can understand the approximate range of the surrounding temperature in real time.

[0004] However, in actual use, in order to improve measurement accuracy, this solution needs to be placed in the environment where measurement is required. However, it is inconvenient to install the indicator in some environments, which has certain limitations. Therefore, a temperature and humidity indicator that can extend the detection range is needed to meet the above requirements. Summary of the Invention

[0005] In order to solve the problems existing in the background technology, the utility model proposes a temperature and humidity indicator with an external probe.

[0006] A temperature and humidity indicator with an external probe includes an indicator body, a socket in the middle of a side of the indicator body, an extendable external probe inserted into the socket, the external probe consisting of a data cable and a plug and a detection probe respectively installed at both ends of the data cable, the plug inserted into the socket, a winding assembly for storing the data cable is also provided on the outer side of the middle of the data cable, and a positioning and installation assembly is provided on the back of the indicator body for facilitating installation and positioning.

[0007] Based on the above, the winding assembly includes a storage cylinder that is sleeved on the outside of the data cable. The internal rotation of the storage cylinder is connected to a rotating shaft, and the data cable is inserted into the middle of the rotating shaft. A knob is fixedly installed at one end of the front of the rotating shaft, and movable grooves are opened in the middle of the left and right sides of the storage cylinder.

[0008] Based on the above, a circle of friction grooves is provided on the outer side of the knob to increase friction and facilitate twisting to drive the shaft to rotate.

[0009] Based on the above, the positioning and mounting assembly includes a piston cylinder fixedly mounted on one side of the back of the indicator body, a hollow rod is slidably inserted into the interior of the piston cylinder, and a suction cup is fixedly mounted on the end of the hollow rod away from the piston cylinder.

[0010] Based on the above, a piston block is fixedly installed at one end of the hollow rod inside the piston cylinder, and the piston block is slidably connected inside the piston cylinder. An air suction hole is opened in the inner center of the suction cup, and an array of through holes is opened on the outer side of the end of the hollow rod close to the piston block.

[0011] Based on the above, a pressure relief hole is provided on the outer side of one end of the piston cylinder away from the suction cup, and eight pressure relief holes are provided in an array around the outer side of the piston cylinder.

[0012] The present invention has substantial features and progress compared to the prior art. Specifically, the present invention can extend the detection distance of the detection probe through the data cable by plugging an external probe into the socket, thereby enabling detection of a limited environment. The data cable can be reeled in by twisting the movable slot to drive the rotating shaft to rotate, thereby facilitating the storage of the data cable. It has the advantages of being able to extend the detection range and adapt to detection in a limited environment, and can also serve the purpose of storing and organizing cables.

[0013] When installing the indicator, the suction cup is pressed so that it is tightly attached to the plane, which will drive the piston block to slide upward along the inner wall of the piston cylinder, and then suck air along the through hole. Therefore, a negative pressure will be formed in the internal space of the suction cup through the suction hole, further improving the adsorption capacity of the suction cup, thereby improving the stability after installation and making the installation more secure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 4 As shown, a temperature and humidity indicator with an external probe comprises an indicator body 1, a socket 2 is provided in the middle of the side of the indicator body 1, an extendable external probe is plugged into the inside of the socket 2, the external probe is composed of a data line 3 and a plug 4 and a detection probe 5 respectively installed at both ends of the data line 3, the plug 4 is plugged into the socket 2, and a winding assembly 6 for storing the data line 3 is further provided on the outside of the middle of the data line 3, and a positioning and mounting assembly 7 for facilitating installation and positioning is provided on the back of the indicator body 1. The positioning and mounting assembly 7 is used to facilitate the installation of the indicator body 1, and then the external probe is plugged into the socket 2 and connected to the indicator body 1, so that the detection probe 5 can be placed in the environment to be detected, which is convenient for detecting some limited environments, and the data line 3 can be conveniently wound and stored through the winding assembly 6;

[0021] When in use, the winding assembly 6 includes a storage cylinder 8 that is sleeved on the outside of the data cable 3. The interior of the storage cylinder 8 is rotatably connected to a rotating shaft 9, and the data cable 3 is inserted into the middle of the rotating shaft 9. A knob 10 is fixedly installed at one end of the front of the rotating shaft 9. A circle of friction patterns is provided on the outside of the knob 10 to increase friction, so that it is easy to turn and drive the rotating shaft 9 to rotate. Active grooves 11 are provided in the middle of the left and right sides of the storage cylinder 8. By turning the active grooves 11, the rotating shaft 9 is driven to rotate, and the data cable 3 is wound. At the same time, the data cable 3 slides along the inner wall of the active groove 11 and is evenly wound around the outside of the rotating shaft 9, thereby being able to store and organize the cables.

[0022] Specifically, the positioning and mounting assembly 7 includes a piston cylinder 12 fixedly mounted on one side of the back of the indicator body 1. A hollow rod 13 is slidably inserted into the interior of the piston cylinder 12. A suction cup 14 is fixedly mounted on the end of the hollow rod 13 away from the piston cylinder 12. By pressing the suction cup 14 against a flat surface, the air inside the suction cup 14 can be squeezed out, and the suction cup 14 will be adsorbed on the flat surface, making it easier to install the indicator.

[0023] Among them, the end of the hollow rod 13 located inside the piston cylinder 12 is fixedly mounted with a piston block 15, and the piston block 15 is slidably connected to the inside of the piston cylinder 12. The center of the suction cup 14 is provided with an air suction hole 16, and the outer side of the end of the hollow rod 13 close to the piston block 15 is provided with a through hole 17. When the suction cup 14 is pressed against the plane, the piston block 15 will slide upward along the inner wall of the piston cylinder 12, and then will inhale along the through hole 17. Therefore, a negative pressure will be formed in the internal space of the suction cup 14 through the air suction hole 16, further improving the adsorption capacity of the suction cup 14, thereby improving the stability after installation;

[0024] In reality, a pressure relief hole 18 is provided on the outer side of the end of the piston cylinder 12 away from the suction cup 14, and eight pressure relief holes 18 are provided in an array around the outer side of the piston cylinder 12. The eight pressure relief holes 18 pass through the piston cylinder 12, so that pressure can be relieved when the piston block 15 slides along the inner wall of the piston cylinder 12, thereby preventing the piston block 15 from being unable to slide.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
