[0002] The cold aisle skylight is an important part of the cold aisle enclosure system, generally arranged at the top of the cold aisle to realize the air enclosure and circulation in the cold aisle, and to meet the fire protection and safety requirements. In case of an emergency, such as a fire alarm trigger, the electro-magnet for fixing the skylight quickly loses power. Based on the eccentric design of the rotating shaft connecting the skylight, at this time, the skylight will open under the action of its own gravity, so as to facilitate the entry of fire fighting gas into the aisle for fire extinguishing.

[0003] However, during the opening process of the existing cold aisle skylight, due to the action of inertia, the skylight often cannot stop directly after reaching the open position, but will rotate back and forth, so it is easy to cause damage to the drive mechanism cooperating with the skylight rotating shaft. Based on this, a solution is needed to solve the problems existing in the prior art. Summary of the Utility Model

[0036] Please refer to Figures 1 to 6 , a damping limiting mechanism for a cold aisle skylight provided by the present utility model includes: a connecting member 1, a limiting shaft 2, and a limiting member 3 that cooperates with the limiting shaft 2.

[0037] Specifically, the connecting member 1 is fixedly connected to an external rotating shaft 4 on an external cold aisle skylight (reference can be made to the skylight body 10), so that when the external rotating shaft 4 rotates, it will drive the connecting member 1 to follow. A limiting groove 5 is provided on the limiting member 3. One end of the limiting shaft 2 is connected to the connecting member 1, and the other end is embedded in the limiting groove 5. The connecting member 1 is used to drive the limiting shaft 2 to follow when the external rotating shaft 4 rotates, so that one end of the limiting shaft 2 embedded in the limiting groove 5 moves in the limiting groove 5, and the limiting shaft 2 is in interference fit with part of the side wall of the limiting groove 5 during the movement process, and the rotation of the external rotating shaft 4 is damped by the interference fit between the limiting shaft 2 and part of the side wall of the limiting groove 5. Exemplarily, the extending direction of the limiting shaft 2 is the same as that of the external rotating shaft 4. In addition, the limiting groove 5 has a first end 6 and a second end 7. During the following process of the limiting shaft 2, the rotation of the external rotating shaft 4 is restricted by abutting against the first end 6 and the second end 7.

[0038] Optionally, the connecting member 1 includes, but is not limited to, a connecting plate, a connecting rod, etc. In the embodiment where the connecting member 1 is a connecting rod, one end of the connecting rod is fixedly connected to the external rotating shaft 4, and the other end is connected to the limiting shaft 2. In the embodiment where the connecting member 1 is a connecting plate, exemplarily, the connecting member 1 can be in the Figures 1 to 4 structure shown. A through hole 11 corresponding to the external rotating shaft 4 can be provided on the connecting member 1. A fixing member 8 is provided at the through hole 11. One end of the fixing member 8 passes through the through hole 11 and is connected to the external rotating shaft 4, and the other end of the fixing member 8 abuts against the connecting member 1, thereby fixedly connecting the connecting member 1 and the external rotating shaft 4. Specifically, the fixing member 8 can be a screw, and the screw passes through the through hole 11 and is screwed to the external rotating shaft 4.

[0039] Optionally, the limiting shaft 2 and the connecting member 1 can be detachably connected or fixedly connected. In the case where the limiting shaft 2 and the connecting member 1 are detachably connected, the limiting shaft 2 can be disassembled to replace the limiting shaft 2 with different specifications and sizes, so as to change the degree of interference fit between the limiting shaft 2 and the partial side walls of the limiting groove 5, and further adjust the damping magnitude when the external rotating shaft 4 rotates. Optionally, the limiting shaft 2 includes but is not limited to any one of a nylon limiting shaft, a rubber limiting shaft, a silica gel limiting shaft, and a TPE limiting shaft. The limiting shaft 2 can also be other shafts made of elastic and flexible materials.

[0040] Exemplarily, the limiting member 3 can be Figures 1 to 4 the shown limiting disc. The limiting member 3 can also have other structures, which are not specifically limited herein. The structure of the limiting member 3 can satisfy the requirement of having a limiting groove 5 formed thereon. Optionally, the limiting groove 5 can have an opening on only one side, or can be as shown in the accompanying drawings with openings on both sides, that is, the limiting groove 5 penetrates through the limiting member 3.

[0041] It can be understood that for the damping limiting mechanism of the cold aisle skylight of the present utility model, by fixedly connecting the connecting member 1 with the external rotating shaft 4 on the cold aisle skylight, the external rotating shaft 4 can drive the limiting shaft 2 on the connecting member 1 to move passively when rotating. During the movement of the limiting shaft 2 in the limiting groove 5, through interference fit with the partial side walls of the limiting groove 5, damping is provided for the rotation of the external rotating shaft 4, and further the rotation speed of the cold aisle skylight when opening and closing is reduced. The limiting shaft 2 limits the further rotation of the external rotating shaft 4 by abutting against the first end portion 6 or the second end portion 7, and further limits the rotatable range of the external rotating shaft 4. The present utility model has good flexibility, and can flexibly set the size of the limiting shaft 2 according to actual situations and requirements, so as to achieve different degrees of interference fit with the side walls of the limiting groove 5, and further flexibly set the damping magnitude received by the external rotating shaft 4. Additionally, the length of the limiting groove 5 can also be flexibly set according to actual situations and requirements, so as to flexibly set the rotatable range of the external rotating shaft 4.

[0042] In a specific embodiment, the limiting shaft 2 is further used for clearance fit with the partial side walls of the limiting groove 5 when moving in the limiting groove 5. Specifically, please refer to Figure 3, the side wall spacing of the limit groove 5 can gradually decrease from the first end 6 to the second end 7. When the limit shaft 2 is in the position of abutting against the first end 6, at this time, it has a clearance fit with the side wall of the limit groove 5 and does not provide damping for the rotation of the external rotating shaft 4. During the process of the limit shaft 2 being driven from the first end 6 to the second end 7, since the side wall spacing of the limit groove 5 gradually decreases, the fit between the limit shaft 2 and the side wall of the limit groove 5 gradually transitions from a clearance fit to an interference fit, and during the continuous movement towards the second end 7, the degree of interference fit gradually increases. Thus, when the external rotating shaft 4 rotates in one direction, the damping it receives gradually increases, facilitating the gradual reduction of the rotation speed of the external rotating shaft 4 and finally making the external rotating shaft 4 stop smoothly. When the external rotating shaft 4 rotates in the other direction, the damping component gradually decreases and finally the damping disappears, so as to facilitate the rotation of the external rotating shaft 4 in the other direction. The side wall spacing of the limit groove 5 and the amplitude of the gradual change in the side wall spacing can be flexibly set according to the size of the limit shaft 2 and actual requirements, and no specific limitation is made here.

[0043] In a specific embodiment, please refer to Figures 1 to 4 , the limit shaft 2 can be a rigid shaft and is preferably integrally formed with the connecting member 1 to improve its structural stability. A flexible limit sleeve 9 is sleeved on the limit shaft 2, and the limit shaft 2 has an interference fit with a part of the side wall of the limit groove 5 through the flexible limit sleeve 9. Optionally, the flexible limit sleeve 9 includes but is not limited to any one of a nylon limit sleeve, a rubber limit sleeve, a silicone limit sleeve, and a TPE limit sleeve. In other embodiments, the flexible limit sleeve 9 can also be other limit sleeves made of elastic and flexible materials.

[0044] Exemplarily, the flexible limit sleeve 9 can include a first limit sleeve 91 sleeved on the limit shaft 2 and a second limit sleeve 92 sleeved on the first limit sleeve 91. Specifically, the limit shaft 2 has an interference fit with a part of the side wall of the limit groove 5 through the first limit sleeve 91, the second limit sleeve 92 is arranged at one end of the first limit sleeve 91 away from the limit groove 5, the outer diameter of the second limit sleeve 92 is greater than the side wall spacing of the limit groove 5, and the second limit sleeve 92 can abut against the side wall of the limiting member 3 after the limit shaft 2 extends into the limit groove 5 to a certain extent, so as to play a role of blocking and limiting.

[0045] In a specific embodiment, please refer to Figure 3 , the limit groove 5 is arc-shaped, and the shape of the limit groove 5 is adapted to the movement trajectory of the limit shaft 2 when the external rotating shaft 4 rotates 90°. Based on this, the rotation range of the external rotating shaft 4 can be limited to 90°. In other embodiments, the shape of the limit groove 5 can also be adapted to the movement trajectory of the limit shaft 2 when the external rotating shaft 4 rotates at other angles, such as 60°, 120°, 180°, etc., and no specific limitation is made here.

[0046] In a specific embodiment, please refer toFigure 6 , a fixing hole 31 may also be formed in the limiting member 3, and the limiting member 3 is used to fixedly connect the bracket 12 supporting the cold channel skylight through the fixing hole 31. Specifically, in practical applications, a screw 13 may be passed through the fixing hole 31 and then screwed to the bracket 12, so as to fix the limiting member 3 to the bracket 12.

[0047] The present utility model also provides a cold channel skylight, please refer to Figure 5 and Figure 6 , including the damping limiting mechanism for the cold channel skylight described in any one of the above embodiments, and the skylight body 10. Specifically, an externally eccentric shaft 4 is provided on the side of the skylight body 10, and the externally eccentric shaft 4 is connected to the connecting member 1 of the damping limiting mechanism. The limiting member 3 is fixed to the bracket 12 by screwing a screw 13 through the fixing hole 31 and then screwing it to the bracket 12 supporting the skylight body 10. The externally eccentric shaft 4 is also connected to a driving device (not shown in the figure), and the driving device is used to drive the externally eccentric shaft 4 to rotate, so that the skylight body 10 can be driven by the externally eccentric shaft 4 to rotate.

[0048] The skylight body 10 is parallel to the horizontal plane in the closed state, and at this time, the limiting shaft 2 of the damping limiting mechanism is located at the position of the first end 6 of the limiting groove 5. When the skylight body 10 is to be opened, the fixing of the skylight body 10 is cancelled. Based on the eccentric design of the externally eccentric shaft 4, the skylight body 10 rotates and opens under the influence of its own weight. During the rotation of the skylight body 10 and the externally eccentric shaft 4 connected thereto, the limiting shaft 2 moves from the first end 6 of the limiting groove 5 to the second end 7. Since the limiting shaft 2 is in interference fit with a part of the side wall of the limiting groove 5, the rotation speed of the externally eccentric shaft 4 will be limited, and when the limiting shaft 2 abuts against the second end 7, the externally eccentric shaft 4 and the skylight body 10 stop stably. Preferably, when the limiting shaft 2 moves to the position where it abuts against the second end 7, the externally eccentric shaft 4 rotates by 90°, so that the skylight body 10 is in a position perpendicular to the horizontal plane, realizing the switching from the closed state to the open state. It can be understood that based on the cooperation with the damping limiting mechanism, the speed of the skylight body 10 will be limited during the opening process, and the final opening position can be limited, so that the skylight body 10 can be opened stably, avoiding damage to the driving device caused by the skylight body 10 rotating back and forth under the influence of inertia.

[0049] In summary, the present utility model provides a damping limiting mechanism and a cold aisle skylight for a cold aisle skylight. Among them, the damping limiting mechanism is connected to an external rotating shaft 4 on the cold aisle skylight through a connecting member 1. A limiting shaft 2 is provided on the connecting member 1. The limiting shaft 2 follows when the external rotating shaft 4 rotates. By abutting against the first end 6 and the second end 7 of the limiting groove 5, the external rotating shaft 4 can be stopped, and it can move within the range of the limiting groove 5, thereby restricting the rotation range of the external rotating shaft 4, restricting the rotatable range of the cold aisle skylight, and preventing reciprocating rotation after rotation in place. In addition, when the limiting shaft 2 follows in the limiting groove 5, it is also in interference fit with part of the side wall of the limiting groove 5, thereby providing damping for the rotation of the external rotating shaft 4, restricting the rotation speed of the external rotating shaft 4, and further restricting the rotation speed of the cold aisle skylight, making its opening and closing more stable. Based on this, the cold aisle skylight provided by the present utility model, in cooperation with the damping limiting mechanism, restricts the speed during rotation, can avoid reciprocating rotation after opening, and avoid damage caused by the reciprocating rotation of the skylight, providing a good user experience.
