[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Dryer rack, such as Figure 1-3 As shown, it includes a base 1 and a base 2 for supporting a drying cylinder disposed on both sides of the base 1, an inspection port 11 is disposed on one side of the base 2, and an inspection door 3 is mounted on the inspection port 11 through a quick lock mechanism 4;

[0020] The inspection port 11 is provided with a sealing groove 12 inwardly in the circumference, and a sealing strip 13 is embedded in the sealing groove 12; wherein the sealing strip 13 is made of rubber. A pressure strip 31 is provided in the circumference of the inspection door 3, and mounting holes for allowing the quick lock mechanism to pass are provided on the inspection door 3 and the pressure strip 31, and a lock hole corresponding to the mounting hole is provided on the sealing groove 12.

[0021] The hanging bar 21 is horizontally arranged on the machine base 2, and the pressure strip 31 is L-shaped. The inspection door 3 is hung on the hanging bar 21 by the pressure strip 31 and is in a horizontal state. During maintenance, the inspection door 3 can be used as a loading platform to facilitate maintenance personnel to take tools. The hanging bar 21 includes a first folded edge 211, a second folded edge 212 and a third folded edge 213. The first folded edge 211 is fixedly arranged on the machine base 2, the third folded edge 213 is parallel to the first folded edge 211, and the second folded edge 212 is respectively perpendicular to the first folded edge 211 and the third folded edge 213. The distance between the third folded edge 213 and the machine base 2 matches the thickness of the pressure strip 31, and the width of the third folded edge 213 is less than the distance from the pressure strip 31 to the inspection door 3. When hanging, the inspection door 3 is set vertically, one side of the pressure strip 31 is inserted between the third folded edge 213 and the machine base 2, and then the inspection door 3 is rotated, and the other side of the pressure strip 31 is supported on the machine base 2 to achieve the hanging of the inspection door 3.

[0022] A quick lock mechanism for a rack access door, such as Figure 1-4 As shown, it includes a locking rod 41, a locking tongue 42, a magnet 43, a rotating shaft 44, a control block 45 and an end seat 46. The locking rod 41 is axially provided with a through hole, the end seat 46 is provided at one end of the locking rod 41, and a locking hole is radially provided at one end of the locking rod 41. The locking tongue 42 is slidably provided in the locking hole, the rotating shaft 44 is provided in the through hole, the magnet 43 is provided on the rotating shaft 44 and is located between the two locking tongues 42. Correspondingly, the tails of the two locking tongues 42 can also be provided with magnets. By using the principle that magnets of the same sex attract each other and opposite sexes repel each other, by changing the direction of the magnet 43, it is possible to switch between attracting the locking tongue 42 and repelling the locking tongue 42. The control block 45 is provided in the end seat 46, and the control block 45 is used to drive the rotating shaft 44 to reciprocate 180°.

[0023] In one embodiment, if Figure 1-4 As shown, a screw rod 441 is disposed at the upper end of the rotating shaft 44, and a screw hole is disposed on the control block 45. By pressing the control block 45, the rotating shaft 44 is driven to rotate through the screw rod 441, thereby controlling the rotation switching direction of the magnet 43.

[0024] In one embodiment, if Figure 1-4 As shown, a guide groove 461 is axially arranged in the end seat 46, and a guide block 451 is arranged at a corresponding position on the side of the control block 45. The guide groove 461 and the guide block 451 are used to guide the axial movement of the control block 45, and a spring 47 is arranged between the control block 45 and the end seat 46. The control block 45 is reset by the spring 47.

[0025] In one embodiment, if Figure 1-4 As shown, the control block 45 includes a pressing block 452 and a driving block 453 . A screw hole is provided on the driving block 453 . The pressing block 452 and the driving block 453 are connected via a connecting rod 454 .

[0026] In one embodiment, if Figure 1-4As shown, an elastic pad 48 is provided at the bottom of the end seat 46. The elastic pad 48 firstly plays a sealing role, and secondly, it allows a certain pressing space between the end seat 46 and the machine base 2. When the inspection door 3 needs to be opened, the staff presses the control block 45, and the elastic pad 48 is slightly compressed. At this time, the driving block 45 drives the rotating shaft 44 to rotate 180°, thereby changing the magnetic pole direction of the magnet 43. At this time, the lock tongue 42 is separated from the lock hole and is attracted by the magnet 43 to shrink inward; because the elastic force of the elastic pad 48 is greater than the elastic force of the spring 47, therefore, in the process of releasing the hand, the magnetic pole direction of the magnet 43 remains unchanged, and the lock tongue 42 smoothly passes through the lock hole of the machine base 2 to achieve unlocking.

[0027] In one embodiment, if Figure 1-4 As shown, an inclined guide edge is provided at the end of the lock tongue 42. After the inspection door 3 is installed on the inspection opening 11, the lock rod 41 is directly inserted into the installation hole and the lock hole, and the lock tongue 42 is compressed and then restored to the extended state by the repulsive force of the magnet. At this time, the lock tongue 42 is buckled on the lock hole, and the inspection door 3 is fixed.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should all be included in the protection scope of the claims of the present invention.
