Description

Technical Field

[0001] This invention relates to the field of constant temperature chamber technology, and in particular to a temperature-controlled constant temperature test chamber. Background Technology

[0002] Electric thermostatic chambers are suitable for fields such as biology, chemical engineering, testing and inspection, metrology calibration, and agricultural science, providing a suitable temperature environment for environmental testing, biochemical reactions, microbial culture, and metrological verification. For example, in cultivation experiments, in order to verify the growth of different experimental subjects under the same conditions, it is necessary to place different experimental subjects together in a test chamber with pre-set constant temperature and humidity for cultivation.

[0003] Because the temperature chamber of a constant temperature test chamber has limited space, the usual solution is to use brackets to divide the internal space of the constant temperature chamber. However, due to different types of test subjects, the space divided by the brackets is often unreasonable and needs to be readjusted. In the process of adjustment, the process of repeatedly taking out and putting in the brackets needs to be repeated. First, it is repetitive work, which makes the re-dividing of the internal space of the constant temperature chamber very complicated. Second, the temperature chamber of many constant temperature test chambers is quite deep, making it inconvenient to take out the brackets. Summary of the Invention

[0029] Secondly, the present invention is described in detail with reference to the schematic diagrams.

[0030] Example 1

[0031] Reference Figures 1-3 The first embodiment of the present invention provides a temperature-controlled constant temperature test chamber, including a constant temperature component 100, which includes a constant temperature chamber shell 101 and an inner liner 102 disposed inside the constant temperature chamber shell 101. The constant temperature chamber shell 101 is provided with a constant temperature incubation chamber 103 and an electrical control chamber, and the constant temperature incubation chamber 103 and the electrical control chamber are separated by the inner liner 102. The constant temperature chamber shell 101 has an opening corresponding to the inner liner 102 and is hinged to a sealing door, which is provided with a visible glass window.

[0032] Specifically, the electrical control cavity is equipped with a temperature control system for adjusting the internal temperature of the constant temperature culture chamber 103 and maintaining a constant internal temperature, a dehumidification system for adjusting the internal humidity of the constant temperature culture chamber 103 and maintaining a constant internal temperature, and a power supply for supplying power to the temperature control system and the dehumidification system.

[0033] The temperature control system includes a temperature controller, an exhaust fan, an intake fan, and a heater. The temperature controller controls the working status of the exhaust fan, the intake fan, and the heater, thereby controlling the internal temperature of the constant temperature incubation chamber 103. The intake fan draws cold air from the outside into the constant temperature incubation chamber 103, and the exhaust fan expels hot air from the constant temperature incubation chamber 103. The heater is installed in the electrical control chamber and located below the inner liner 102 to increase the internal temperature of the constant temperature incubation chamber 103.

[0034] Specifically, a temperature sensor is also installed inside the constant temperature incubation chamber 103 to monitor the temperature, which, together with the temperature control system, can better regulate the internal temperature of the constant temperature incubation chamber 103.

[0035] Specifically, a display panel is also installed on the constant temperature chamber shell 101 to display the temperature of the constant temperature incubation chamber 103. At the same time, the working mode of the temperature controller and the set temperature of each chamber can be set on the display panel.

[0036] Furthermore, the constant temperature culture chamber 103 is provided with multiple horizontally arranged culture racks 200, which divide the constant temperature culture chamber 103 into multiple culture layers from top to bottom. The constant temperature culture chamber 103 is also provided with support components 300 for supporting the culture racks 200.

[0037] Specifically, the support assembly 300 includes two mounting brackets 301 symmetrically arranged on the inner walls of both sides of the inner liner 102, and a support member 302 movably mounted on the mounting brackets 301.

[0038] In this example, intake and exhaust fans are used to ensure rapid air circulation within the electrical cavity, thereby quickly reducing the temperature of the electrical cavity. A heater is installed at the bottom of the inner liner 102, and the heated air rises while the cold air at the top of the constant temperature incubation chamber 103 descends, creating convection. This ensures that the air throughout the constant temperature incubation chamber 103 is fully heated, improving temperature uniformity. The constant temperature incubation chamber 103 is divided into multiple incubation layers by the incubation rack 200, making full use of the internal space of the constant temperature incubation chamber 103.

[0039] Example 2

[0040] Reference Figure 3 , Figure 4 ,as well as Figures 6-8 This is the second embodiment of the present invention, which differs from the first embodiment in that: the mounting bracket 301 includes a vertically arranged slide rod 301a and a connecting seat 301b symmetrically arranged at both ends of the slide rod 301a and fixed to the inner liner 102 by screws; the support member 302 includes a sleeve 302a slidably sleeved on the outside of the slide rod 301a, two spaced arc brackets 302b, and a connecting bracket 302c disposed between the sleeve 302a and the arc brackets 302b.

[0041] Specifically, the ring bracket has its opening facing upwards, and the outermost metal rod of the culture rack 200 is placed on the ring bracket, thus the ring bracket supports the culture rack 200. The ring bracket is connected to the sleeve 302a through the connecting frame 302c. The sleeve 302a can slide along the sliding rod 301a, thereby driving the culture rack 200 supported by the ring bracket to move synchronously. That is, the culture rack 200 can move up and down in the constant temperature culture chamber 103 to adjust the size of each culture layer space and make reasonable allocation of the constant temperature culture chamber 103.

[0042] Furthermore, an arc plate 302d is movably disposed between the two arc brackets 302b. A limiting strip 302e perpendicular to the arc bracket 302b is provided on one side of the arc plate 302d. A protruding strip 302f is provided on the side wall of the arc plate 302d adjacent to the arc bracket 302b, and an arc groove 302b-1 with the contour of the protruding strip 302f is provided on the side wall of the arc bracket 302b adjacent to the arc plate 302d.

[0043] Specifically, the protrusion 302f can slide along the arc groove 302b-1, causing the arc plate 302d to flip and be placed above the outermost metal rod of the culture rack 200 supported on the circular bracket. This changes the outermost metal rod of the culture rack 200 from a semi-enclosed support state to a fully enclosed fixed state, preventing the culture rack 200 from falling off the support 302 due to vibration or other external forces.

[0044] Furthermore, the slide bar 301a is provided with a guide groove 301a-1 extending along its axial direction on the outside, and the sleeve 302a is provided with a guide block 302g that is consistent with the vertical cross-sectional profile of the guide groove 301a-1 on the inner wall.

[0045] Specifically, the guide block 302g slides with the guide groove 301a-1 to ensure that the support 302 can move along the axis of the slide rod 301a, and at the same time, it also plays a circumferential limiting role for the support 302 to prevent the support 302 from rotating or shifting.

[0046] Furthermore, the support assembly 300 also includes a locking member 303 disposed at one end of the sleeve 302a and used to fix the sleeve 302a. The locking member 303 includes a locking sleeve 303a movably sleeved on the outside of the slide bar 301a, a T-shaped ring 303b disposed at one end of the sleeve 302a, and a hook-shaped cylinder 303c movably sleeved on the outside of the T-shaped ring 303b and fixedly connected to the locking sleeve 303a.

[0047] Furthermore, the outer wall of the slide bar 301a has several equally spaced locking grooves 301a-2 arranged from top to bottom. The locking grooves 301a-2 are perpendicular to the guide grooves 301a-1. The inner wall of the locking sleeve 303a is provided with a sliding groove 303a-1 corresponding to the locking grooves 301a-2. The sliding groove 303a-1 is door-shaped. A locking rod 303d that can be embedded into the locking groove 301a-2 is provided in the sliding groove 303a-1. A spring 303e for pushing the locking rod 303d into the locking groove 301a-2 is provided in the sliding groove 303a-1.

[0048] Specifically, after the locking rod 303d is embedded in the locking groove 301a-2, the locking sleeve 303a can be locked and fixed. After the locking rod 303d is removed from the locking groove 301a-2, the limiting position of the locking sleeve 303a is released, and the hook-shaped cylinder 303c and the T-shaped ring 303b rotate and engage. Therefore, the hook-shaped cylinder 303c and the T-shaped ring 303b, while connecting the locking sleeve 303a and the sleeve 302a, can also lock and unlock. Under normal conditions, the locking rod 303d is embedded in the locking groove 301a-2. In the state within 2, when it is necessary to unlock, simply rotate the locking sleeve 303a. The locking rod 303d is pushed out of the locking groove 301a-2 by the pressure of the sliding rod 301a, and moves to the other side of the sliding along with the rotating locking sleeve 303a. When it is necessary to relock, simply continue to rotate the locking sleeve 303a. Under the action of the spring 303e, the locking rod 303d is pushed into the locking groove 301a-2 to complete the locking. After the locking sleeve 303a is locked and fixed, the sleeve 302a connected to the locking sleeve 303a is also locked and fixed.

[0049] In this embodiment, by setting a support member 302, the arc bracket 302b supports the culture rack 200, and then flipping the arc plate 302d to fully surround the culture rack 200, preventing the culture rack 200 from falling off the support member 302 due to vibration or other external forces; at the same time, the sleeve 302a can slide along the slide rod 301a to adjust the position and height of the culture rack 200 in the constant temperature culture chamber 103, adjust the size of each culture layer space, and reasonably allocate the constant temperature culture chamber 103; by setting a locking member 303, after adjustment, the locking rod 303d is engaged with the locking groove 301a-2 to complete the locking and fixing of the support member 302, that is, to fix the height position of the culture rack 200.

[0050] The remaining structure is the same as that in Example 1.

[0051] Example 3

[0052] Reference Figure 5 and Figure 8This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: the connecting seat 301b is provided with an insertion hole that matches the contour of the end face of the slide rod 301a, and the connecting seat 301b is provided with a locking component 400 for fixing the slide rod 301a at the corresponding insertion hole; the locking component 400 includes a cylindrical tube 401 and a cap 402 that is movably sleeved on the outside of the cylindrical tube 401. The cylindrical tube 401 is provided with a through hole 401a that matches and intersects the contour of the insertion hole, and the end of the slide rod 301a passes through the insertion hole and is inserted into the through hole 401a.

[0053] Furthermore, the end of the slide bar 301a is provided with a locking groove 301a-2 along its circumferential direction, the outer wall of the column cylinder 401 is provided with an annular groove 401b, the inner ring surface of the column cap 402 is provided with a number of trapezoidal blocks 403 arranged circumferentially corresponding to the annular groove 401b, a locking bead 404 is provided between two adjacent trapezoidal blocks 403, the column cylinder 401 is also provided with a number of ball holes 401c arranged circumferentially and connecting the annular groove 401b and the through hole 401a; the side of the ball hole 401c near the through hole 401a is provided with an anti-disengagement block 405 to prevent the locking bead 404 from disengaging.

[0054] Specifically, in this embodiment, a locking assembly 400 is provided on the connecting seat 301b to fix the slide rod 301a. In use, the end of the slide rod 301a is inserted through the insertion hole and into the through hole 401a. The column cap 402 is rotated, and the trapezoidal block 403 on its inner ring surface presses the locking bead 404. The locking bead 404 moves into the ball hole 401c and partially passes through the ball hole 401c and is stuck in the locking groove 301a-3, thus completing the fixation of the slide rod 301a.

[0055] The remaining structure is the same as that in Example 2.
