DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all the embodiments.

[0021] Embodiment one:

[0022] Combined with Figs. 1-3The specific structure is as follows: first, the support bottom piece 1 is a hollow cuboid structure made of high-strength plastic material, has good compression resistance and deformation resistance, and is provided with a fixed plate 2 on one side of the bottom. The size of the fixed plate 2 is customized according to actual installation requirements. An adjusting groove 3 is formed in the sidewall of the middle part of the support bottom piece 1, and an adjusting cap 4 is installed in the adjusting groove 3. The shape of the adjusting groove 3 is matched with the adjusting cap 4, which can ensure that the adjusting cap 4 is not exposed and will not interfere with subsequent installation. The adjusting cap 4 is a cylindrical structure, and an internal thread hole is arranged at the center position of the adjusting cap 4. A preliminary position adjusting piece 5 is slidably arranged in the cavity of the support bottom piece 1. The preliminary position adjusting piece 5 is also made of high-strength plastic material, and its shape is matched with the shape of the cavity inside the support bottom piece 1, so that it can freely slide in the cavity. A threaded rod 6 is vertically and fixedly connected to the bottom of the preliminary position adjusting piece 5. The external thread of the threaded rod 6 is matched with the internal thread hole of the adjusting cap 4 to form a threaded transmission structure. By rotating the adjusting cap 4, the threaded rod 6 can be lifted and lowered to act on the preliminary position adjusting piece 5. A guide groove 7 is symmetrically formed in the sidewall of the preliminary position adjusting piece 5 on both sides of the threaded rod 6. The length of the guide groove 7 penetrates most of the height of the preliminary position adjusting piece 5. A guide column 8 is installed in the guide groove 7. The guide column 8 is a cylindrical metal rod, and its both ends are fixed between the sidewalls of the support bottom piece 1 through nuts. The guide column 8 and the guide groove 7 are matched in a clearance fit, which can ensure smooth sliding of the preliminary position adjusting piece 5 in the cavity of the support bottom piece 1, and can also accurately guide the movement of the preliminary position adjusting piece 5 to prevent it from deviating or shaking during lifting. The end of the preliminary position adjusting piece 5 is designed with a sliding connection structure for connecting with a meticulous position adjusting piece 9. Specifically, the end of the preliminary position adjusting piece 5 is provided with a dovetail groove, which has good guiding and bearing capacity. The end of the meticulous position adjusting piece 9 is provided with a dovetail block matched with the dovetail groove. The dovetail block and the dovetail groove are matched through sliding to enable the meticulous position adjusting piece 9 to slide linearly along the direction of the dovetail groove at the end of the preliminary position adjusting piece 5. In order to ensure the smooth sliding of the meticulous position adjusting piece 9, guide grooves 10 are formed in the end walls of the support bottom piece 1. A recess groove 11 for installing a fan is formed in the sidewall of the meticulous position adjusting piece 9. The shape and size of the recess groove 11 are matched with the installation base of the fan to tightly fit the fan base and ensure the stability of the fan installation. Ventilation openings 13 are also formed in the recess groove 11. The shape and size of the ventilation openings 13 are designed according to the ventilation requirements of the fan. Locking bolts 14 are arranged at the bottom of the cavity of the ventilation openings 13. The locking bolts 14 penetrate the end of the meticulous position adjusting piece 9 and abut against the preliminary position adjusting piece 5. When it is necessary to fix the position of the meticulous position adjusting piece 9 on the preliminary position adjusting piece 5, the locking bolts 14 can be tightened to firmly lock the meticulous position adjusting piece 9 at any position through friction.Fine tuning of the fan position is achieved.

[0023] In the embodiment, the vertical fixed connection between the bracket bottom piece 1 and the fixed plate 2 ensures that the included angle between the two is 90 degrees. The fixed plate 2 is regularly distributed with several groups of waist-shaped holes 15. In the actual installation process, the waist-shaped holes 15 give the installer flexible adjustment space, greatly improving the adaptability, and effectively avoiding the problem of uneven stress on the bracket caused by installation errors.

[0024] In the embodiment, the outer surface of the adjusting cap 4 is provided with anti-skid lines, which are evenly distributed along the circumferential direction of the adjusting cap 4. This can effectively prevent slipping during the force application process. Even in a humid environment or if the operator's hands are greasy, it can still ensure a stable grip feeling, thereby achieving accurate adjustment of the fan installation position.

[0025] In the embodiment, the width of the guide groove 10 is greater than the width of the fine position adjusting piece 9. This size difference can ensure that the fine position adjusting piece 9 can be flexibly slid out of the guide groove 10, avoiding interference.

[0026] In the embodiment, a specially designed rubber ring 16 is tightly embedded on the side wall of the bracket bottom piece 1 corresponding to the ventilation opening 13. When the rubber ring 16 is subjected to pressure, it can produce a larger deformation space, thereby forming a tighter sealing effect. After the fan is installed, the rubber ring can tightly fit the surface of the equipment, effectively filling the gap and enhancing the sealing of the ventilation opening, preventing air leakage. At the same time, it can also buffer the vibration and noise generated during the operation of the fan, providing a more stable operating environment for the fan.
