Description

Technical Field

[0001] The utility model relates to the technical field of laboratory testing, and more specifically to a temperature and humidity calibration auxiliary device for environmental testing equipment. Background Art

[0002] When calibrating conventional air medium type environmental test equipment, the sensor probes should be placed in accordance with the calibration specifications, with quick action, accurate position, and uniform placement, and the distance between the probes and the inner wall should be controlled. Try to avoid opening the door of the equipment for a long time, which will cause the temperature and humidity inside and outside to exchange too long and too frequently, thus affecting the storage and cultivation of the specimens inside, or causing the re-constant temperature and humidity to take too long, affecting the calibration efficiency.

[0003] The publication number CN220568164U retrieved after retrieval, the utility model discloses an auxiliary device for temperature and humidity calibration of environmental testing equipment, including a fixed base plate, a supporting column is installed on the top outer wall of the fixed base plate, a sliding column is slidably clamped on the supporting column, a clamping assembly is installed on the side wall of the sliding column, the clamping assembly is movably clamped with a limit block, and connecting rings are slidably clamped on the sliding columns. By loosening the tightening screw 2, the sliding plate can slide on the rotating rod, so that the position of the sensor on the sliding block can be moved, and by loosening the tightening screw 1, the sliding block can slide on the sliding plate, thereby further moving the position of the sensor on the sliding block, and by loosening the locking nut on the connecting screw, the rotating rod can be rotated separately, so that the position of the sensor on the sliding block can be adjusted separately. The device can increase the adjustment range of the sensor, which is conducive to improving the ability of the auxiliary device to be better applicable to environmental testing equipment of different sizes.

[0004] Although the above technology can achieve wide-angle adjustment, the rotation and connection mechanisms used are operated by pressing and tightening. The steering structure uses a nut and a screw to tighten. When the nut structure is loosened, the arm structure becomes loose, and it is necessary to manually maintain its balance and reset the nut to fix it after adjusting the angle. It needs to be equipped with tools such as wrenches when using it, which is cumbersome to operate. In addition, when used in an environment with high humidity, the nut is prone to rust, affecting its normal use and inconvenient operation. In view of this, we propose a temperature and humidity calibration auxiliary device for environmental test equipment. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide an auxiliary device for temperature and humidity calibration of environmental test equipment to solve the technical problems of the current rotating angle adjustment mechanism being cumbersome to operate, poor stability, and easy to rust and affect normal use.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions: An auxiliary device for calibrating the temperature and humidity of an environmental test equipment, comprising a base, an adjusting mechanism and an inner cylinder. A vertical rod is fixed at the middle of the upper end surface of the base. The adjusting mechanism is sleeved on the vertical rod. An arm unfolding mechanism is annularly and arrayedly distributed on the outer side of the adjusting mechanism. Positioning holes are equidistantly formed on the vertical rod, and pins are inserted into the positioning holes. The pins are attached to the lower side of the adjusting mechanism.

[0007] When the present utility model is in use, the operator adjusts the position of the height-adjusting sleeve on the vertical rod, and then realizes the height limitation through the cooperation of the positioning hole and the pin. When adjusting the angle, rotate the screw rod to drive the inner slider to rise threadedly. The inner slider drives the clamping strip to close through the linkage mechanism. After the clamping strip is separated from the clamping groove, the operator can manually rotate the frame body to deflect it on the outer cylinder through the rotating sleeve to realize the adjustment of the angle. After the adjustment is completed, rotate the screw rod in the reverse direction to realize the reset and locking of the clamping strip. Pull out the pull rod outward, and then limit it by rotating the tightening screw rod, and the adjustment of the unfolding length can be realized. The temperature and humidity are detected by the sensors built in the detection box at the outer end of the pull rod. The locking structure is displaced by the threaded driving method, and the locking is completed by the built-in locking structure to realize the fixation of the angle. The convenient operation method reduces the operation difficulty and can complete the operation without the assistance of tools. At the same time, when the locking is separated, the arm unfolding mechanism maintains stability at the same time, and there is no need for manual support and calibration. At the same time, the built-in structure design avoids the damage of the linkage structure and ensures its service life.

[0008] Preferably, the adjusting mechanism is composed of a sleeve, a connecting seat and an outer cylinder. The sleeve is slidably sleeved on the vertical rod. There are three connecting seats, and the three connecting seats are annularly and arrayedly distributed on the outer side of the sleeve. The outer cylinder is inserted and installed on the connecting seat.

[0009] Preferably, clamping strips are rotatably installed in the openings on both sides of the outer cylinder through rotating shafts. The inner cylinder is fixed inside the outer cylinder. A screw rod is rotatably installed at the upper end of the outer cylinder.

[0010] Preferably, an inner slider is slidably installed inside the inner cylinder. Side grooves are formed on both sides of the inner cylinder. Linkage mechanisms are arranged on both sides of the inner slider, and the linkage mechanisms pass through the side grooves and are installed on the inner sides of the clamping strips. The lower end of the screw rod threadedly penetrates through the inner slider.

[0011] Preferably, the linkage mechanism is composed of a linkage rod and a universal joint. The upper end of the linkage rod is rotatably installed on the inner slider through a hinge. The linkage rod and the universal joint are rotatably connected through a hinge. The rear end of the universal joint is fixed on the inner side of the clamping strip.

[0012] Preferably, the arm unfolding mechanism is composed of a frame body, a pull rod and a rotating sleeve. A rotating sleeve is fixed at the rear end of the frame body, and the rotating sleeve is rotatably sleeved on the outer cylinder.

[0013] Preferably, a card slot is annularly arranged on the inner side of the rotating sleeve, and after the card strip deflects through the rotating shaft, the outer end of the card strip is clamped in the corresponding card slot.

[0014] Preferably, the pull rod is slidably inserted into the outer end of the frame body, a detection box is installed at the outer end of the pull rod, and a tightening screw rod is threadedly installed through the upper side of the outer end of the frame body.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. By designing an adjusting mechanism and an inner cylinder, when in use, manually rotate the top of the corresponding screw rod, the inner slider is driven by the thread to rise and fall. When the inner slider rises and falls, the card strip is driven to rotate and open through the linkage mechanism, so that the outer end of the card strip is clamped in the card slot of the rotating sleeve, realizing the angle locking of the boom mechanism. The locking structure is displaced by the thread driving method, and the locking is completed by the built-in locking structure, realizing the fixing of the angle. The convenient operation method reduces the operation difficulty, and the operation can be completed without the assistance of tools. At the same time, when the locking is separated, the boom mechanism maintains stability at the same time, without manual support and calibration. At the same time, the built-in structure design avoids the damage of the linkage structure and ensures its service life.

[0017] 2. The utility model also designs a linkage mechanism. When the inner slider rises and falls driven by the thread, the inner slider synchronously drives the top ends of the two side linkage rods to displace. When the upper end of the linkage rod descends, its lower end moves outwards. The connection between the lower end of the linkage rod and the steering joint drives the card strip to deflect outwards. The card strip is pushed to deflect around the shaft it rotates on, so that the outer side of the card strip is clamped in the card slot to realize the above-mentioned locking operation. The downward force is converted into an outward pushing force through the cooperation of the linkage rod and the steering joint, realizing the opening and closing operation of the card strip and reducing the difficulty of manual operation.

There are three connecting seats 402, and the three connecting seats 402 are distributed in an annular array on the outer side of the sleeve 401. The outer cylinder 403 is inserted and installed on the connecting seat 402. The plug pin 202 is inserted into the corresponding positioning hole 201 to support the lower side of the sleeve 401, realizing the height limitation of the adjustment mechanism 4.

The inner slider 501 drives the card strips 405 to move through the linkage mechanisms 6.

[0028] As Figures 2 to 8As shown in the figure, a temperature and humidity calibration auxiliary device for an environmental test equipment according to the present utility model includes a base 1, an adjustment mechanism 4 and an inner cylinder 5.
