Example 2
Referring to fig. 1 to 9, a second embodiment of the present invention is based on the previous embodiment, and is different from the previous embodiment in that:
the connecting unit 200 comprises a connecting cylinder 201 connected with the moving element 104 and a connecting seat 202 fixedly connected with the heat dissipation frame 301, the connecting cylinder 201 is cylindrical, one end of the connecting cylinder 201 is provided with a flange, and the flange is fixedly connected with the moving element 104; the connecting cylinder 201 is detachably connected with the connecting socket 202. One end part of the connecting cylinder 201 far away from the moving piece 104 is provided with a radial fixing column 201 a; the connection holder 202 is provided with a connection hole 202a, and the connection cylinder 201 can be inserted into the connection hole 202 a.
An annular groove 202b is formed in the connecting hole 202a, the inner diameter of the annular groove 202b is larger than that of the connecting hole 202a, a rotating disc 203 is arranged in the annular groove 202b, the rotating disc 203 can rotate in the annular groove 202b, the rotating disc 203 is connected with a rotating column 203a, and the rotating column 203a can be embedded into the connecting cylinder 201.
Wherein, the side of the rotating column 203a is provided with a spiral groove 203 b. The spiral groove 203b extends along a spiral line, so when the rotating column 203a is embedded in the connecting cylinder 201, one end of the fixing column 201a is embedded in the spiral groove 203b, and along with the approaching of the connecting cylinder 201 and the connecting seat 202, under the action of the fixing column 201a, the rotating column 203a is embedded in the connecting cylinder 201 while rotating until the fixing column 201a moves to the tail end of the spiral groove 203 b.
Furthermore, the side wall of the connecting hole 202a is provided with a guide groove 202c along the axial direction, when the connecting cylinder 201 is connected with the connecting seat 202, one end of the fixing column 201a is embedded into the guide groove 202c, the other end of the fixing column 201a is embedded into the spiral groove 203b, and under the action of the guide groove 202c, the connecting cylinder 201 and the connecting seat 202 cannot rotate relatively and can drive the rotating column 203a to rotate.
Preferably, a first ratchet gear 204 is disposed in the connecting cylinder 201, the first ratchet gear 204 is fixed on the flange, the first ratchet gear 204 is an end ratchet, the rotating column 203a is disposed with a second through hole 203c, an adjusting cylinder 205 is disposed in the second through hole 203c, and a second ratchet gear 205a is disposed at an end of the adjusting cylinder 205 close to the first ratchet gear 204. The second ratchet gear 205a is also an end ratchet, so when the second ratchet gear 205a is engaged with the first ratchet gear 204, since the first ratchet gear 204 is fixed and the second ratchet gear 205a is not fixed in the axial direction, the second ratchet gear 205a can only rotate in one direction, and when the rotation column 203a is to be disengaged from the connecting cylinder 201, the second ratchet gear 205a needs to rotate in the opposite direction, i.e. needs to be separated from the first ratchet gear 204, which needs to be able to shift the second ratchet gear 205a in the axial direction.
The side surface of the second through hole 203c is provided with a limit groove 203d along the axial direction, the outer side of the adjusting cylinder 205 is provided with a limit boss 205b, and the limit boss 205b is embedded into the limit groove 203 d. The limiting boss 205b is matched with the limiting groove 203d, so that the adjusting cylinder 205 cannot rotate relative to the second through hole 203c and can only deviate along the axial direction, when the fixed column 201a moves to the tail end of the spiral groove 203b, the second ratchet gear 205a and the first ratchet gear 204 are already meshed, the rotation of the rotating column 203a is limited, and when the connecting cylinder 201 and the connecting hole 202a are separated, the rotating column 203a needs to rotate, so that the connecting cylinder 201 and the connecting seat 202 cannot be separated when the second ratchet gear 205a and the first ratchet gear 204 are in a meshed state.
Furthermore, an adjusting groove 202d is formed in the end face, away from the connecting cylinder 201, of the connecting hole 202a, a conical round table 205c is connected to one end, located in the adjusting groove 202d, of the adjusting cylinder 205, and a spring 206 is arranged between the conical round table 205c and the bottom of the adjusting groove 202 d. Therefore, under the action of the spring 206, the second ratchet-toothed wheel 205a is urged to engage with the first ratchet-toothed wheel 204; the diameter of one end of the conical round platform 205c contacting the adjusting cylinder 205 is smaller than that of one end far away from the adjusting cylinder 205; the side surface of the adjusting groove 202d is provided with a third through hole 202e penetrating to the outside of the connecting base 202, only the adjusting pin 207 is arranged in the third through hole 202e, when the adjusting pin 207 is operated to push the conical round platform 205c, because the cross section of the conical round platform 205c is an inclined surface, the axial movement of the adjusting pin 207 is converted into the axial movement of the conical round platform 205c, namely the second ratchet gear 205a is far away from the first ratchet gear 204, and at this time, the rotating column 203a has a rotational degree of freedom, so that the connecting base 202 can be operated to be separated from the connecting cylinder 201.
Preferably, a reset groove 202f is formed in the third through hole 202e, the diameter of the reset groove 202f is larger than the inner diameter of the third through hole 202e, a disc 207a is disposed on a portion of the adjusting pin 207 located in the reset groove 202f, and an elastic member 208 is disposed between the disc 207a and an end surface of the reset groove 202f close to the adjusting groove 202 d. The elastic element 208 is a pressure spring, and in a default state, due to the action of the elastic element 208, the end of the adjusting pin 207 is in contact with the end with the larger diameter of the tapered circular truncated cone 205c, and when the adjusting pin 207 is pushed, the adjusting pin 207 moves toward the center of the connecting hole 202a along the axial direction of the third through hole 202e, and further pushes the tapered circular truncated cone 205 to make the second ratchet wheel 205a away from the first ratchet wheel 204.
The working principle of the embodiment is as follows: after the installation of the installation unit 100 is completed, the heat dissipation unit 300 needs to be installed in the frame 101, at this time, the connecting cylinder 201 can be inserted into the connecting hole 202a, and the rotating column 203a is inserted into the connecting cylinder 201 while rotating until the fixing column 201a moves to the tail end of the spiral groove 203b, so that the installation can be completed, and at this time, the connection of the connection unit 200 is stable and cannot be directly separated; when the heat dissipating unit 300 needs to be detached, the adjusting pin 207 needs to be pressed down from the side of the connecting base 202, and the connecting base 202 can be removed after being driven by the tapered circular truncated cone 205 c.
