Description

Technical Field

[0001] This utility model relates to the field of air outlet structure technology, specifically to the air inlet and outlet arrangement structure for constant temperature environment of electronic equipment. Background Technology

[0002] An electronic equipment constant temperature chamber is a closed test space used to simulate and control specific environmental conditions (such as temperature, humidity, air pressure, etc.). It is designed to provide a stable test or working environment for electronic equipment, components or systems to verify their performance, reliability and environmental adaptability.

[0003] However, the ventilation duct structure of the existing electronic device constant temperature chamber is not stable in actual use, and a large number of eddies and turbulence are generated, which affects the temperature and normal airflow inside the electronic device constant temperature chamber. To address this problem, an air inlet and outlet arrangement structure for the constant temperature environment of electronic devices is provided. Utility Model Content

[0004] The purpose of this utility model is to provide an air inlet and outlet arrangement structure for a constant temperature environment of electronic equipment, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: an air inlet and outlet arrangement structure for a constant temperature environment of electronic equipment, including a ventilation duct, a gradient tube at the rear end of the ventilation duct, an outlet duct at the rear end of the gradient tube, a bracket at the front end of the ventilation duct, a rotating column rotatably connected to the middle of the bracket via a bearing, multiple fan blades at the rear end of the rotating column, a pulley fixedly sleeved at the front end of the rotating column, a fixing plate on one side of the outer wall of the ventilation duct, a motor at the rear end of the fixing plate, the output end of the motor extending to the front end of the fixing plate and fixedly sleeved with a fixing block, the fixing block being a hexagonal block, an adjustment component on each side of the fixing block, a support block on the side of each adjustment component away from the fixing block, and a belt sleeved between the multiple support blocks and the pulley.

[0005] Preferably, each of the adjusting components includes a lead screw, a movable cylinder screwed to the outer wall of the lead screw, the movable cylinder being fixedly connected to a support block, a worm gear being fixedly sleeved on the outer wall of the lead screw, a frame being provided on the outer wall of the fixed block, a worm being rotatably connected to the rear side of the inner cavity of the frame via a bearing, the front end of the worm extending to the front end of the frame, and the worm meshing with the worm wheel.

[0006] Preferably, a telescopic cylinder is provided on one side of the outer wall of the fixed block, and a telescopic rod is slidably inserted into the inner cavity of the telescopic cylinder, and the telescopic rod is fixedly connected to the support block.

[0007] Preferably, the inner cavity of the telescopic cylinder is formed in a limiting groove, and a limiting block is slidably embedded in the inner cavity of the limiting groove. The limiting block is fixedly connected to the outer wall of the telescopic rod.

[0008] Preferably, the inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both dovetail-shaped.

[0009] Preferably, each of the worm gears has a sprocket at its front end, and the sprockets are rotatably connected by a chain.

[0010] Preferably, one of the worm gears has a knob at its front end, and the outer circumference of the knob is provided with several anti-slip ridges.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By setting up a gradient tube, the airflow inside the ventilation duct can gradually enter the smaller cross-section air outlet cavity. Under the action of the gradient tube, the generation of eddies and turbulence can be reduced. The motor drives the fixed block, adjustment component and support block to rotate, which in turn drives the belt pulley, rotating column and fan blade to rotate. This allows the fan blade to adjust the airflow speed inside the ventilation duct. When eddies or turbulence occur inside the ventilation duct, the fan blade rotation speed can be reduced to reduce the generation of eddies and turbulence. This solves the problem that the airflow is not stable in the actual use of the ventilation duct structure of the electronic equipment constant temperature room, which generates a lot of eddies and turbulence, thus affecting the temperature and normal airflow inside the electronic equipment constant temperature room.

[0013] 2. Rotate the knob to make one of the worm gears rotate. Since the sprockets are connected by a chain, when one worm gear drives one sprocket to rotate, other sprockets will drive other worm gears to rotate, allowing multiple worm gears to rotate simultaneously. Because the worm gear meshes with the worm wheel, when the worm gear rotates, the worm wheel will drive the lead screw to rotate. Under the rotational force of the thread on the outer wall of the lead screw, when the lead screw rotates, the moving cylinder will drive the support block to slide, so that the distance between the support block and the fixed block is fitted, thereby adjusting the speed of the pulley, and thus realizing the adjustment of the fan blade speed.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a constant temperature environment air inlet and outlet arrangement structure for electronic equipment, including a ventilation pipe 1, a gradient pipe 2 at the rear end of the ventilation pipe 1, an outlet pipe 3 at the rear end of the gradient pipe 2, a bracket 4 at the front end of the ventilation pipe 1, a rotating column 5 rotatably connected to the middle of the bracket 4 via a bearing, multiple fan blades 6 at the rear end of the rotating column 5, a pulley 7 fixedly sleeved at the front end of the rotating column 5, a fixing plate 8 on one side of the outer wall of the ventilation pipe 1, a motor 9 at the rear end of the fixing plate 8, the output end of the motor 9 extending to the front end of the fixing plate 8 and fixedly sleeved with a fixing block 10, the fixing block 10 being a hexagonal block, an adjustment component on each side of the fixing block 10, a support block 11 on the side of each adjustment component away from the fixing block 10, and multiple support blocks 11 sleeved with the outer side of the pulley 7. With a belt and a gradient tube 2, the airflow inside the ventilation duct 1 gradually enters the smaller cross-section air outlet duct 3. Under the action of the gradient tube 2, the generation of eddies and turbulence can be reduced. The motor 9 drives the fixed block 10, the adjustment component and the support block 11 to rotate, which in turn drives the belt pulley 7, the rotating column 5 and the fan blade 6 to rotate. This allows the fan blade 6 to adjust the airflow speed inside the ventilation duct 1. When eddies or turbulence occur inside the ventilation duct 1, the rotation speed of the fan blade 6 can be reduced to reduce the generation of eddies and turbulence. This solves the problem that the airflow in the ventilation duct 1 structure of the electronic equipment constant temperature chamber is unstable during actual use, which generates a large number of eddies and turbulence, affecting the temperature and normal airflow inside the electronic equipment constant temperature chamber.

[0021] In this embodiment, each adjustment component includes a lead screw 12, a movable cylinder 13 screwed to the outer wall of the lead screw 12, the movable cylinder 13 being fixedly connected to the support block 11, a worm gear 14 fixedly sleeved on the outer wall of the lead screw 12, a frame 15 provided on the outer wall of the fixed block 10, a worm 16 rotatably connected to the rear side of the inner cavity of the frame 15 via a bearing, the front end of the worm 16 extending to the front end of the frame 15, the worm 16 meshing with the worm gear 14, by rotating the worm 16, the worm 16 drives the worm gear 14 to rotate. Since the worm 16 meshes with the worm gear 14, when the worm 16 rotates, the worm gear 14 can drive the lead screw 12 to rotate. Under the action of the rotational force of the thread on the outer wall of the lead screw 12, when the lead screw 12 rotates, the movable cylinder 13 can drive the support block 11 to slide, so that the distance between the support block 11 and the fixed block 10 is sleeved, thereby adjusting the speed of the pulley 7, thereby realizing the adjustment of the speed of the fan blade 6.

[0022] In this embodiment, a telescopic cylinder 19 is provided on one side of the outer wall of the fixed block 10. A telescopic rod 20 is slidably inserted into the inner cavity of the telescopic cylinder 19. The telescopic rod 20 is fixedly connected to the support block 11. Under the combined action of the telescopic rod 20 and the telescopic cylinder 19, the support block 11 can always slide along a straight line. It can also prevent the support block 11 and the moving cylinder 13 from rotating with the lead screw 12 when the lead screw 12 rotates, thereby improving the stability of the adjustment component during use.

[0023] In this embodiment, the inner cavity of the telescopic cylinder 19 is formed in the limiting groove 21, and the inner cavity of the limiting groove 21 is slidably embedded with the limiting block 22. The limiting block 22 is fixedly connected to the outer wall of the telescopic rod 20, so that one end of the telescopic rod 20 is always inserted into the inner cavity of the telescopic cylinder 19, which improves the stability of the adjustment component during use.

[0024] In this embodiment, the inner cavity of the limiting groove 21 and the outer wall of the limiting block 22 are adapted to each other and are both dovetail-shaped, so that one end of the limiting block 22 is always embedded in the inner cavity of the limiting groove 21, preventing the limiting block 22 from dislodging from the inner cavity of the limiting groove 21, causing the telescopic rod 20 to dislodge from the inner cavity of the telescopic cylinder 19, thereby improving the stability of the telescopic assembly during use.

[0025] In this embodiment, each of the multiple worm gears 16 has a sprocket 17 at its front end. The multiple sprockets 17 are rotatably connected by a chain. Since the sprockets 17 are rotatably connected by a chain, when one of the worm gears 16 drives one of the sprockets 17 to rotate, the other sprockets 17 can drive the other worm gears 16 to rotate, so that the multiple worm gears 16 rotate simultaneously.

[0026] In this embodiment, a knob 18 is provided at the front end of one of the worm gears 16, and several anti-slip ridges are provided on the outer circumference of the knob 18.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
