Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1-2, a case cooling fan for a computer, includes a fan housing 1, a mounting hole 2 is formed in each of four corners of a case of the fan housing 1, a fixing plate 11 is fixedly connected to one side of the inside of the mounting hole 2 of the fan housing 1, a threaded through hole is formed in the middle of a plate body of the fixing plate 11, a threaded rod 12 is connected to the fixing plate 11 at the threaded through hole, three connecting rods 8 are fixedly connected to the fan housing 1 at the middle of the inside of the mounting hole 2 at equal intervals, a sliding sleeve 7 is fixedly connected to one end of each of the three connecting rods 8, a sliding rod 6 is slidably connected to the inside of each of the three sliding sleeves 7 at equal intervals, the same connecting plate 10 is fixedly connected to one end of each of the three sliding rods 6 close to the fixing plate 11, a fixing block 5 is fixedly connected to the other end of each of the three sliding rods 6, springs 9 are fixedly connected to the connecting plate 10 and the three sliding sleeves 7 at the outside of the three sliding rods 6 respectively, three clamping rods 3 are rotatably connected to one side of the fan housing 1 far away from the fixing plate 11 at equal intervals inside of the mounting hole 2, and torque springs 4 are fixedly connected between the three clamping rods 3 and the fan housing 1.

Three kelly 3 all are L shape, and three kelly 3's horizontal support arm one end all extends to the outside of mounting hole 2. One end of the threaded rod 12, which is positioned outside the mounting hole 2, is fixedly connected with a knob 13, and anti-skid paint is coated outside the knob 13. Both sides of fan housing 1 all are equipped with otter board 16, and two otter boards 16 are the fixedly connected with bolt 14 of one end department of one side that is close to each other, and the equal fixedly connected with locating plate 15 in both ends department of one side inner wall of fan housing 1, the locating hole has all been seted up to the plate body of two locating plates 15, and two bolts 14 are respectively with two locating hole looks adaptations. Both ends department that fan housing 1 kept away from locating plate 15 one side all seted up the screw thread through-hole, and fan housing 1 has bolt 18 at two equal threaded connection in screw thread through-hole department, and the equal fixedly connected with spud pile 17 of one side department that two otter boards 16 are close to each other and keep away from bolt 14, and two spud piles 17 are in same axis in two bolts 18 respectively.

The working principle is as follows: when radiator fan's installation, align mounting hole 2 with the installing port of computer machine case of fan housing 1, then twist knob 13 drives threaded rod 12 and rotate, threaded rod 12 can promote connecting plate 10 and remove this moment, connecting plate 10 promotes fixed block 5 through slide bar 6 and removes, fixed block 5 promotes kelly 3 and can make it deflect, can accomplish the installation between radiator fan and the quick-witted case after kelly 3 deflects 90 degrees, and because the shell of seting up radiator fan installing port department on the quick-witted case often is thinner, so machine case shell can not exert an influence to the deflection of kelly 3.
