[0028] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] The temperature and humidity chamber of the present invention will be described below with reference to the accompanying drawings.

[0030] like Figures 1 to 3 As shown, the utility model provides a temperature and humidity chamber, wherein the temperature and humidity chamber comprises:

[0031] The box body 1 is formed with a test space 11 for placing a sample, and a storage groove 12 is formed on the inner wall of the test space 11;

[0032] The detection device 2 includes a first hinged seat 21, a flexible adjustment rod 22 and a detector 23. The first hinged seat 21 is arranged in the storage groove 12. The bending direction of the flexible adjustment rod 22 is adjustable. One end of the flexible adjustment rod 22 is installed on the first hinged seat 21 and has a lying state and an upright state. The other end of the flexible adjustment rod 22 is connected to the detector 23. The flexible adjustment rod 22 is used to drive the detector 23 to be accommodated in the storage groove 12 in the lying state, and drive the detector 23 to extend to the sample in the test space 11 in the upright state.

[0033] When the above-mentioned temperature and humidity chamber is used, it includes a chamber body 1 and a detection device 2. The chamber body 1 forms a test space 11 for placing samples, and a storage groove 12 is formed on the inner wall of the test space 11. The detection device 2 includes a first hinge seat 21, a flexible adjustment rod 22 and a detector 23. The first hinge seat 21 is arranged in the storage groove 12, and the bending direction of the flexible adjustment rod 22 is adjustable. One end of the flexible adjustment rod 22 is installed on the first hinge seat 21 and has a lying state and an upright state. The other end of the flexible adjustment rod 22 is connected to the detector 23. Before the sample test, the operator turns the flexible adjustment rod 22 to put it in an upright state, and the flexible adjustment rod 22 and the detector 23 extend out of the storage slot 12 as a whole. By adjusting the flexible adjustment rod 22, the detector 23 can be made as close to the sample as possible, thereby accurately measuring the temperature and humidity data of the space around the sample; after the sample test is completed, the operator first adjusts the flexible adjustment rod 22 to straighten it, and then presses down the flexible adjustment rod 22 to put it in a lying state, thereby accommodating the detection device 2 as a whole into the storage slot 12 to protect the detector 23, and also facilitate the removal or placement of the sample.

[0034] In the embodiment of the utility model, the flexible adjustment rod 22 includes a terminal short section 221, a head short section 222, and a plurality of movable short sections 223 sequentially connected in series between the terminal short section 221 and the head short section 222, each movable short section 223 is adjustable between two adjacent short sections, the terminal short section 221 is hinged on the first hinge seat 21 and has a lying state and an upright state, and the head short section 222 is connected to the detector 23. Through the form of the above-mentioned multi-section connecting rod, the shape, position and angle of the flexible adjustment rod 22 can be adjusted to a large extent, so as to change the shape of the flexible adjustment rod 22 for different types of test samples, ensure that the detector 23 is as close to the sample as possible, and improve the reliability of the test data.

[0035] Specifically, the movable short section 223 can be configured as follows: Figure 1 The damping ball joint short section shown in the figure includes a short section body and a ball head extending from one end of the short section body, and a ball socket is formed at the other end of the short section body. The ball head and the ball socket of the connected damping ball joint short section are matched and connected, and there is a certain friction torque between the ball head and the ball socket, so that the damping ball joint short section can remain in a fixed state at any angle position and will not change its position due to its own gravity, so that the detector 23 can be in a suspended state close to the sample.

[0036] Specifically, the movable short section 223 can also be set as a magic ruler short section (not shown in the figure), the magic ruler short section is in the shape of a triangular prism and is formed with a first splicing surface and a second splicing surface, the first splicing surface and the second splicing surface are set at an angle, the first splicing surface of a magic ruler short section is spliced ​​with the second splicing surface of the adjacent magic ruler short section at the rear end, and the magic ruler short section at the front end can rotate along the second splicing surface of the magic ruler short section at the rear end, so as to adjust the position and angle of each magic ruler short section, thereby changing the overall shape of the flexible adjustment rod 22, so that the detector 23 is close to the sample. In addition, compared with the damping ball joint short section, the flexible adjustment rod 22 composed of the magic ruler short sections can also be folded and stored, so that the length of the flexible adjustment rod 22 can be designed to be larger. Further, the first joint surface and the second joint surface are set to a square, the angle between the first joint surface and the second joint surface is set to 90°, a limiting concave hole is formed at each of the four corners of the first joint surface, and a limiting protrusion is formed at each of the four corners of the second joint surface. The limiting protrusion of each magic ruler short section extends into the limiting concave hole of the adjacent magic ruler short section correspondingly, and the limiting concave hole and the limiting protrusion play a shaping role. Only when the operator applies external force to rotate the magic ruler short section, the limiting protrusion will fall out of the limiting concave hole, that is, each magic ruler short section has four rotation adjustment positions of 0°, 90°, 180°, and 270°, so as to change the shape of the flexible adjustment rod 22 according to different types of test samples, ensure that the detector 23 is as close to the sample as possible, and improve the reliability of the detection data.

[0037] More specifically, the connection between the magic ruler short sections can be through an elastically stretchable connecting strip or a magnetic connection. When the connecting strip is selected, the magic ruler short section is formed with a through hole extending from the first joint surface to the second joint surface, one end of the connecting strip is connected to the end short section 221, and the other end of the connecting strip is connected to the head short section 222; when the magnet is selected, the magic ruler short section is a hollow structure, the magnet is placed in the magic ruler short section, the center of the first joint surface is formed with a rotating concave hole, and the central protrusion of the second joint surface is formed with a rotating part corresponding to the rotating concave hole.

[0038] Specifically, the movable short section 223 can also be set as Figure 4 In the structure shown, the movable short section 223 includes a short section body and an articulated ball head 2231 extending from one end of the short section body, and an articulated ball socket is formed at the other end of the short section body. A plurality of slots 2232 are arranged on the articulated ball head, and a limiting portion is protruded from the articulated ball socket. When the limiting portion extends into the slot 2232, the adjacent movable short sections 223 are relatively fixed, and the limiting portion can only be disengaged from the slot when sufficient external force is applied. Furthermore, when the adjacent slots are arranged at 90°, that is, when two adjacent movable short sections 223 are vertical in space, they are relatively fixed. This kind of vertical direction that can be fixed in space only includes three directions: X, Y, and Z. The movable short sections 223 in other directions can rotate relatively, but cannot be fixed.

[0039] It should be noted that, in the above embodiment, the positions of the first joint surface and the second joint surface may also be swapped.

[0040] In the embodiment of the utility model, the first hinged seat 21 includes a seat body and a damping shaft that can be rotatably disposed on the seat body along the width direction of the receiving groove 12, a first limiting plane is formed on the suspended shaft section of the damping shaft, a hinge hole for the damping shaft to pass through is formed at one end of the terminal short section 221 away from the movable short section 223, and a second limiting plane that abuts against the first limiting plane is formed on the wall of the hinge hole. The swing angle of the terminal short section 221 can be adjusted by the damping shaft, see Figure 3 The first hinge seat 21 is arranged at one end of the storage slot 12, and the terminal short section 221 can be adjusted within the range of 0-90 degrees. Specifically, a fork-shaped connecting portion is formed at one end of the terminal short section 221 away from the movable short section 223, and hinge holes are formed on the two connecting ear plates of the fork-shaped connecting portion. The seat body is arranged in an E shape, and two swinging spaces are formed corresponding to the two connecting ear plates.

[0041] In an embodiment of the utility model, the head end short section 222 includes a short section body and a short section cover, the short section body is connected to the movable short section 223, and an accommodating space for accommodating the detector 23 is formed at one end of the short section body away from the movable short section 223, and the short section cover is detachably covered at the entrance of the accommodating space and is formed with a detection port for the probe of the detector 23 to extend out. The detachable setting of the head end short section 222 facilitates the replacement of the detector 23. Specifically, a threaded connection can be adopted between the short section body and the short section cover. Furthermore, an elastic member (such as sponge, rubber) can be arranged in the short section body, and the elastic member has a certain deformation ability, which can fix the detector 23 within a certain volume range, and avoid the detector 23 shaking in the head end short section 222 during the adjustment of the flexible adjustment rod 22.

[0042] In the embodiment of the utility model, the flexible adjustment rod 22 is configured as a gooseneck tube, which is a metal piece that can be bent arbitrarily and determine the direction. The detector 23 can also be brought close to the sample through the gooseneck tube.

[0043] In the embodiment of the utility model, a screen controller is provided on the outside of the box body 1 and is connected to the detector 23 in communication. The screen controller is used to display the data detected by the detector 23. The detector 23 and the screen controller can be wirelessly connected or wired. When a wired connection is adopted, the connecting wires of the detector 23 extend out of the test space 11 through the flexible adjustment rod 22 and the first hinge seat 21 in sequence and are electrically connected to the screen controller. Specifically, the first limit surface and the end surface of the damping shaft are provided with threading holes. The connecting wires extend out of the detection space at a 90° angle through the two threading holes on the damping shaft to avoid squeezing the connecting wires when the terminal short section 221 rotates.

[0044] In the embodiment of the utility model, the storage groove 12 is disposed on the bottom plate of the box body 1 and is disposed close to the entrance of the test space 11 , and the storage groove 12 extends along the width direction of the entrance of the test space 11 .

[0045] For a larger box body 1, the storage slot 12 is farther away from the sample. In order to prevent the torque on the flexible adjustment rod 22 from exceeding its bearing limit (for example, sagging due to excessive gravity), in the embodiment of the utility model, an auxiliary support assembly is also provided on the bottom wall of the test space 11. The auxiliary support assembly is provided between the storage slot 12 and the center point of the bottom wall, and includes a second hinge seat, a first support rod and a second support rod. One end of the first support rod is hinged on the second hinge seat, and the other end of the first support rod forms an opening for the flexible adjustment rod 22 to pass through. One end of the second support rod is hinged on the middle section of the first support rod, and the other end of the second support rod is used to abut the bottom wall of the test space 11. Further, the bottom wall can also be provided with a hidden groove for storing the auxiliary support assembly, and the hidden bottom surface is formed with a plurality of positioning structures, and the plurality of positioning structures are sequentially arranged at intervals along the length direction of the hidden groove. One end of the second support rod away from the first support rod is used to rotatably abut against a positioning structure, thereby adjusting the height of the opening on the first support rod. Furthermore, the second hinge seat can be arranged to be movably arranged along the hidden groove to adjust the lateral position of the opening. The box body 1 can be a magnetic metal, and a magnet can be arranged at the bottom of the second hinge seat to achieve position fixing.
