Description

Technical Field

[0001] The utility model relates to the technical field of air cooler installation, in particular to an air cooler fixing device for vibration reduction. Background Art

[0002] Air coolers are used in low-temperature freezer warehouses with forced air circulation cooling. They are a type of air cooling equipment. Air coolers for cold storage are dry air cooling equipment. As an important component of cold storage, air coolers are crucial to the refrigeration effect of cold storage. In order to ensure the service life of air coolers, they are usually installed in a relatively stable position in the cold storage.

[0003] The related art (publication number: CN210179977U) discloses a cold storage air cooler with adjustable wind direction, and the disclosed technical solution is: the rack can be slid in the slide rail to drive the rotating shaft to drive several louvers to rotate at the same time, and the surface of the louver will form an angle with the rotation center line of the fan, so that the cold air blown out from the fan will turn when passing through the louver, thereby cooling a specific direction in the cold storage and improving the cooling effect;

[0004] In the above disclosed technical solutions, the following problems were found in the related technologies: after the air cooler is fixed in the cold storage position through the outer shell, due to the manufacturing process, materials, design and other reasons, some parts of the fan such as the rotor and blades have certain quality deviations, which makes the fan produce unstable vibrations during operation. This vibration will not only damage the fan itself, but also affect the surrounding structures and equipment through the transmission of the fan, and cause the fixing frame to loosen, and finally cause the air cooler to fall and be damaged. In addition, the unstable vibration of the air cooler will also cause noise to the surrounding environment. In this regard, we propose a new type of vibration reduction air cooler fixing device.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include prior art information that does not constitute known to ordinary technicians in the field.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The following is a combination of specific implementation cases and attached Figure 1-5 The present invention is further described below, but the present invention is not limited to these embodiments.

[0032] A vibration-reducing air cooler fixing device comprises a mounting frame 1, and a fixing frame 2 is symmetrically and slidably provided on the side wall of the mounting frame 1. The two fixing frames 2 slide on the surface of the mounting frame 1 in parallel and vertically fit, and the mounting frame 1 is provided with an adjusting and fixing mechanism for driving the fixing frame 2 to position the air cooler. The two fixing frames 2 are relatively moved by adjusting the fixing mechanism, so that the air cooler is fixed between the two fixing frames 2. A support rod 3 is rotatably provided at the upper corner of the inner wall of the fixing frame 2, and a first connecting frame 15 is fixedly installed at the two right-angled inner walls above the fixing frame 2, and a first fixed shaft 23 is fixedly embedded and installed inside the first connecting frame 15, and a first connecting member 26 is fixedly installed on the upper end of the support rod 3, and the first connecting member 26 is movably sleeved on the outside of the first fixed shaft 23 through a mounting hole opened on the surface and penetrating the inner cavity. The upper end of the support 3 is hinged to the right-angled corner above the fixing frame 2.

[0033] The bottom of the inner wall of the fixing frame 2 is rotatably provided with a movable rod 4, and the lower end of the movable rod 4 is fixedly installed with a second connecting member 25. The second connecting frame 10 is fixedly installed at the center position of the bottom of the inner wall of the fixing frame 2, and the second fixed shaft 24 is fixedly embedded and installed inside the second connecting frame 10. The second connecting member 25 is movably sleeved on the outside of the second fixed shaft 24 through a mounting hole opened on the surface and penetrating the inner cavity, so that the lower end of the movable rod 4 is hinged to the center position of the bottom of the inner wall of the fixing frame 2.

[0034] The other end of the support rod 3 is sleeved on the outside of the other end of the movable rod 4, and the lower end of the support rod 3 is sleeved on the outside of the movable rod 4 through the slot hole, and the aperture of the slot hole corresponds to the movable rod 4, so that the support rod 3 and the movable rod 4 form a telescopic rod body component. The support rod 3 and the movable rod 4 are connected by an elastic component, and the movable rod 4 and the inside of the movable cavity at the lower end of the support rod 3 are connected to the movable rod 4 by an elastic component.

[0035] The elastic deformation of the elastic component increases the stability of the fixing frame 2, so that after the air cooler is fixed on the mounting frame 1 through the two fixing frames 2, it has a vibration reduction effect, increases the anti-fall effect of the air cooler, and thus ensures the stability of the air cooler during the working process. The elastic component reduces the vibration of the working process, thereby reducing the noise caused by the air cooler and protecting the surrounding environment.

[0036] The elastic component includes a groove cavity 9 opened at the bottom end of the support rod 3. The groove cavity 9 is opened along the inner cavity at the lower end of the support rod 3, and a connected movable cavity 27 is continuously opened on the inner wall of the groove cavity 9, and the aperture of the movable cavity 27 is smaller than the aperture of the groove cavity 9. An movable cavity 27 is opened at the top of the inner wall of the groove cavity 9, and a slide bar 7 is fixedly installed at the top of the movable rod 4. One end of the slide bar 7 is fixedly installed at the center position of the upper end of the movable rod 4, and the other end of the slide bar 7 extends to the inside of the movable cavity 27 after passing through the groove cavity 9. The aperture of the movable cavity 27 corresponds to that of the slide bar 7, so that the slide bar 7 slides in contact with the inner wall of the movable cavity 27. The other end of the slide bar 7 passes through the groove cavity 9 and extends to the inner cavity of the movable cavity 27. A first elastic member 8 is arranged between the top of the inner wall of the groove cavity 9 and the top of the movable rod 4, and the first elastic member 8 is sleeved on the outer wall of the slide bar 7.

[0037] The first elastic member 8 can be a compression spring, one end of the first elastic member 8 is fixedly mounted on the top of the inner wall of the groove cavity 9, and the other end of the first elastic member 8 is fixedly mounted on the top of the movable rod 4. The first elastic member 8 is movably sleeved on the outside of the sliding rod 7, so that the first elastic member 8 fits on the outer wall of the sliding rod 7 and slides telescopically.

[0038] When the fixing frame 2 vibrates during the operation of the air cooler, the fixing frame 2 vibrates. When the fixing frame 2 is deformed by the vibration force, the movable rod 4 slides against the inner wall of the groove cavity 9, and the movable rod 4 drives the slide bar 7 to slide against the inner wall of the movable cavity 27. The elastic deformation of the first elastic member 8 has a buffering effect, thereby ensuring the stability of the fixing frame 2, preventing the deformation of the fixing frame 2 caused by vibration, and further ensuring the stability of the air cooler.

[0039] It is worth mentioning that the adjustment and fixing mechanism includes a screw 5 rotatably arranged on the side wall of the mounting frame 1, and the fixing frame 2 is symmetrically threadedly connected to the outside of the screw 5. Two first mounting seats 14 parallel to each other are vertically fixedly installed on the surface of the mounting frame 1, and bearings are embedded and installed on the opposite surfaces of the two first mounting seats 14, and the two ends of the screw 5 are embedded and installed inside the two bearings. Two parts of external threads with opposite threads and the same pitch are symmetrically opened on the outer wall of the screw 5 from the center position to both sides, and the two fixing frames 2 are connected to the two parts of the external threads on the outer surface of the screw 5 through threaded through holes that penetrate the inner cavity on the surface. When the screw 5 rotates, the two fixing frames 2 move relative to each other or back to back.

[0040] The motor 13 is fixed by a motor seat on the surface of the mounting frame 1 and at a position opposite to one of the first mounting seats 14. The motor 13 is electrically connected to an external power source through a wire, and the output shaft of the motor 13 passes through the inner cavity of the corresponding first mounting seat 14 and is fixedly connected to the corresponding end of the lead screw 5. A stable guide assembly is provided on the side wall of the mounting frame 1 to prevent the position of the fixing frame 2 from shifting. The stable guide assembly ensures the stability of the moving direction of the fixing frame 2, thereby ensuring the stability of the air cooler after being fixed.

[0041] When fixing the air cooler, the motor 13 is connected to a power source so that the output shaft of the motor 13 drives the lead screw 5 to rotate, so that the two fixing frames 2 connected by the external threads of the lead screw 5 move relatively. The distance between the two fixing frames 2 is adjusted according to the number of air coolers, so that it can be suitable for fixing air coolers of different specifications and different types, and thus has applicability.

[0042] In addition, the stable guide assembly includes a guide rod 11 arranged on the side wall of the mounting frame 1, and the guide rod 11 is parallel to the lead screw 5, and the fixing frame 2 is sleeved on the outside of the guide rod 11. Two second mounting seats 17 parallel to each other are vertically fixed on the surface of the mounting frame 1, and the two ends of the guide rod 11 are respectively vertically fixed on the opposite surfaces of the two second mounting seats 17. A through hole penetrating the inner cavity is opened on the surface of the fixing frame 2 near the bottom, and the aperture of the through hole corresponds to the specification of the guide rod 11. The fixing frame 2 is movably sleeved on the outside of the guide rod 11 through the through hole.

[0043] In the process of rotating the lead screw 5 to adjust the positions of the two fixing frames 2, the fixing frames 2 are made to slide on the outside of the guide rod 11. The guide rod 11 parallel to the lead screw 5 ensures the stability of the moving direction of the fixing frames 2, avoids the position deviation of the fixing frames 2, and thus ensures the stability of the air cooler after being fixed.

[0044] In addition, a buffer component for protecting the surface of the cooling fan is provided on the positioning contact surface of the fixing frame 2 .

[0045] Further, the buffer assembly includes a buffer seat 6 disposed on one side of the fixing frame 2, a limit block 21 is disposed on the other side of the fixing frame 2, and a buffer rod 18 is disposed between the limit block 21 and the buffer seat 6. The buffer rod 18 penetrates the inner cavity of the fixing frame 2, a second elastic member 28 is disposed between the buffer seat 6 and the fixing frame 2, and the second elastic member 28 is sleeved on the outside of the buffer rod 18. One end of the second elastic member 28 is fixedly mounted on the opposite surfaces of the two fixing frames 2, and the other end of the second elastic member 28 is fixed on the surface of the buffer seat 6, and the buffer seat 6 is located on the opposite surfaces of the two fixing frames 2.

[0046] The second elastic member 28 may be a compression spring. One end of the buffer rod 18 is fixedly mounted on the surface of the buffer seat 6 relative to the fixing frame 2, and the other end of the buffer rod 18 passes through the fixing frame 2 and is fixedly connected to the stop block 21. The second elastic member 28 is movably sleeved on the outside of the buffer rod 18, so that the second elastic member 28 fits on the outer wall of the buffer rod 18 and slides telescopically.

[0047] When the two fixing frames 2 move relative to each other to fix the air cooler, when the fixing frame 2 drives the buffer seat 6 to contact the surface of the air cooler, the second elastic member 28 increases the buffer force of the contact surface with the air cooler, thereby preventing the surface of the air cooler from being damaged by excessive force, thereby protecting the air cooler.

[0048] The buffer seat 6 is made of elastic material, and the buffer seat 6 can be made of rubber material. The elastic material can protect the surface of the air cooler.

[0049] A support plate 19 for supporting the bottom of the air cooler is fixedly installed at the bottom of the fixing frame 2. By installing the extra support plate 19 at the bottom of the fixing frame 2, the support plate 19 supports the bottom of the air cooler, thereby ensuring the stability of the air cooler after being fixed.

[0050] The side wall of the mounting frame 1 is evenly provided with weight-reducing holes 12. By providing the weight-reducing holes 12 penetrating the inner cavity on the mounting frame 1, the weight of the mounting frame 1 is reduced, thereby bringing convenience to the construction process of relevant personnel.

[0051] The present embodiment is a vibration reduction air cooler fixing device, and its working principle is as follows: firstly, the mounting frame 1 is fixed on a suitable cold storage installation surface.

[0052] Then the air cooler is placed on the bottom support plate 19 between the two fixing frames 2. Then the motor 13 is connected to the power supply so that the output shaft of the motor 13 drives the screw 5 to rotate, so that the two fixing frames 2 connected by the external threads of the screw 5 move relative to each other, and the air cooler is fixed between the two fixing frames 2.

[0053] When the fixing frame 2 vibrates during the operation of the air cooler, the fixing frame 2 vibrates. When the fixing frame 2 is deformed by the vibration force, the movable rod 4 slides against the inner wall of the groove cavity 9, and the movable rod 4 drives the sliding rod 7 to slide against the inner wall of the movable cavity 27, and the elastic deformation of the first elastic member 8 plays a buffering effect.
