Description

Technical Field

[0001] This utility model relates to the field of constant temperature and humidity test chamber technology, specifically a constant temperature and humidity test chamber with interface protection. Background Technology

[0002] A constant temperature and humidity test chamber is an experimental device used to simulate specific temperature and humidity environmental conditions. It is widely used in product performance testing, quality control, and reliability verification in industries such as electronics, automobiles, materials, pharmaceuticals, and food.

[0003] Existing constant temperature and humidity test chambers are typically equipped with external connection interfaces such as power cords and sensor cables to meet the needs of equipment power supply, data transmission, and signal monitoring. However, the interface design of current test chambers has certain shortcomings: their interface structure is simple and lacks effective cable fixing devices. In actual use, cables are prone to loosening or even falling off due to accidental contact, pulling, or equipment vibration, leading to test interruption, data loss, or equipment failure, affecting the continuity and reliability of testing. Utility Model Content

[0004] The purpose of this invention is to provide a constant temperature and humidity test chamber with interface protection to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature and humidity test chamber with interface protection, comprising a constant temperature and humidity test chamber body, wherein an interface is provided on the back of the constant temperature and humidity test chamber body, and a protective component and a limiting component are provided on the back of the constant temperature and humidity test chamber body;

[0006] The protective components include:

[0007] A fixed housing is used to stabilize its internal mechanisms.

[0008] A circular plate is used to drive the synchronous movement of various components.

[0009] A cable retainer is used to secure cables.

[0010] Preferably, the fixed shell is fixed to the back of the constant temperature and humidity test chamber body. A circular plate is rotatably connected to the inner wall of the fixed shell. A through hole is opened on the outer surface of the circular plate. A circular rod abuts against the inner wall of the through hole. A fixing block is fixed to the end of the circular rod away from the through hole. The fixing block is slidably connected to the inner wall of the fixed shell on the side away from the circular plate. A movable hole is opened on the outer surface of the fixed shell. A movable hole is opened on the outer surface of the fixed shell. A limiting frame is fixed to the end of the circular rod away from the through hole. The limiting frame is slidably connected to the outer surface of the fixed shell. A stabilizing hole is opened on the outer surface of the circular plate. A locking tooth is fixed to the outer surface of the circular plate. The locking tooth is rotatably connected to the back of the constant temperature and humidity test chamber body. A gear is fixed to the cylinder. The gear meshes with the locking tooth. A knob is fixed to the top of the cylinder. When the knob is turned, the cylinder and the gear will rotate synchronously, and the locking tooth and the circular plate will rotate together. The inner wall of the through hole contacts the outer surface of the round rod, pushing the fixing block and the limiting frame to move radially, so that the limiting frame applies a limiting effect on the cable plug.

[0011] Preferably, the limiting component includes a fixing rod, which is fixed to the back of the constant temperature and humidity test chamber body. A sliding plate is slidably connected to the fixing rod. A fixing ring is fixed to the end of the sliding plate away from the fixing rod. A sliding rod is provided on the outer surface of the fixing ring. The sliding rod passes through the fixing ring and is slidably connected to the fixing ring. A clamping block is fixed to the outer surface of the sliding rod. A spring is fixed to the outer surface of the clamping block. The end of the spring away from the clamping block is fixed to the inside of the fixing ring. When the sliding plate is pressed, the rubber pad of the clamping block is pressed tightly against the cylindrical surface, and the cylinder is locked by friction.

[0012] Preferably, the through hole is arc-shaped, so that when the circular plate rotates, it can synchronously drive the circular rod, the fixed block, and the limiting frame to move radially.

[0013] Preferably, the cylinder is configured as a cone shape, which can be used to tighten and limit the cylinder when the fixing ring and clamping block move downward.

[0014] Preferably, a rubber pad is fixed on the side of the clamping block away from the slide bar to increase friction and facilitate the positioning of the cylinder.

[0015] Compared with the prior art, this utility model provides a constant temperature and humidity test chamber with interface protection, which has the following beneficial effects:

[0016] 1. This constant temperature and humidity test chamber with interface protection, through its protective components, ensures that when the cable plug is connected to the interface, rotating the knob, via a cylinder, gears, locking teeth, and a circular plate, brings the inner wall of the through hole into contact with the outer surface of the circular rod, pushing the fixing block and the limiting frame to move radially. At this time, the limiting frame applies a limiting effect to the cable plug. This achieves a stable lock between the interface and the cable, effectively preventing loosening and ensuring normal equipment operation.

[0017] 2. This constant temperature and humidity test chamber with interface protection, through the set limit component, when the sliding plate is pressed, the fixing ring drives the clamping block to move down, so that the rubber pad is tightly attached to the surface of the cylinder, and the cylinder is locked by friction to prevent the knob from turning accidentally.

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a constant temperature and humidity test chamber with interface protection, including a constant temperature and humidity test chamber body 1, an interface 2 is provided on the back of the constant temperature and humidity test chamber body 1, and a protective component 3 and a limiting component 4 are provided on the back of the constant temperature and humidity test chamber body 1; the protective component 3 includes: a fixed shell 30, a circular plate 31, a through hole 32, a circular rod 33, a fixed block 34, a movable hole 35, a limiting frame 36, a stabilizing hole 37, a locking tooth 38, a gear 39, a cylinder 300, and a knob 301.

[0026] A fixed shell 30 is fixed to the back of the constant temperature and humidity test chamber body 1. A circular plate 31 is rotatably connected to the inner wall of the fixed shell 30. A through hole 32 is opened on the outer surface of the circular plate 31. A circular rod 33 is abutted against the inner wall of the through hole 32. A fixing block 34 is fixed to the end of the circular rod 33 away from the through hole 32. The fixing block 34 is slidably connected to the inner wall of the fixed shell 30 on the side away from the circular plate 31. A movable hole 35 is opened on the outer surface of the fixed shell 30. The movable hole 35 is passed through the movable hole 35 at the end of the circular rod 33 away from the through hole 32. A limit frame 36 is fixed to the end of the circular rod 33 away from the through hole 32. The limit frame 36 is slidably connected to the fixed shell 30. The outer surface of the shell 30 has a stabilizing hole 37. A retaining tooth 38 is fixed to the outer surface of the circular plate 31, with one end of the retaining tooth 38, away from the circular plate 31, passing through the stabilizing hole 37. A cylinder 300 is rotatably connected to the back of the constant temperature and humidity test chamber body 1. A gear 39 passes through and is fixed to the cylinder 300, meshing with the retaining tooth 38. A knob 301 is fixed to the top of the cylinder 300. The through hole 32 is arc-shaped, and the cylinder 300 is conical. When the knob 301 is rotated, the cylinder 300 and gear 39 rotate synchronously, causing the retaining tooth 38 and the circular plate 31 to rotate together. At this time, the inner wall of the through hole 32 contacts the outer surface of the circular rod 33, pushing the fixing block 34 and the limiting frame 36 to move radially, causing the limiting frame 36 to exert a limiting effect on the cable plug. This linkage mechanism achieves a secure lock between the interface 2 and the cable, effectively preventing loosening and ensuring normal equipment operation.

[0027] The limiting component 4 includes a fixing rod 40, which is fixed to the back of the constant temperature and humidity test chamber body 1. A sliding plate 41 is slidably connected to the fixing rod 40. A fixing ring 42 is fixed to the end of the sliding plate 41 away from the fixing rod 40. A sliding rod 44 is provided on the outer surface of the fixing ring 42, passing through the fixing ring 42 and slidably connected to it. A clamping block 43 is fixed to the outer surface of the sliding rod 44, and a spring 45 is fixed to the outer surface of the clamping block 43. The end of the spring 45 away from the clamping block 43 is fixed to the inner side of the fixing ring 42. A rubber pad is fixed to the side of the clamping block 43 away from the sliding rod 44. When the sliding plate 41 is pressed, the fixing ring 42 moves downward, causing the rubber pad of the clamping block 43 to press tightly against the surface of the cylinder 300, locking the cylinder 300 using friction and preventing the knob 301 from rotating accidentally. This design avoids accidental external contact or vibration interference, ensuring the stability of the gear 39, the locking teeth 38, and the circular plate 31.

[0028] When connecting cables, insert the cable plug into interface 2. Then, turn knob 301 to simultaneously rotate cylinder 300 and gear 39. At the same time, clamping teeth 38 and circular plate 31 rotate synchronously. The inner wall of through hole 32 abuts against the outer surface of circular rod 33, causing fixing block 34 and limit frame 36 to move radially synchronously. This limits the cable plug, thus protecting interface 2 and cable and preventing loosening that could affect the normal use of the equipment. Pressing slide plate 41 will simultaneously move fixing ring 42 downward. The rubber pad on the surface of clamping block 43 abuts against the outer surface of cylinder 300, clamping cylinder 300 through friction and preventing knob 301 from rotating further. This prevents accidental operation or vibration from affecting the stability of gear 39, clamping teeth 38, and circular plate 31.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
