Description

Technical Field

[0001] This utility model relates to the field of physiotherapy equipment technology, specifically to a canopy release device. Background Technology

[0002] In existing fumigation therapy equipment, the opening and closing of the chamber lid typically relies on electrically driven mechanical devices. These devices effectively control the opening and closing of the chamber lid during normal operation.

[0003] However, in the event of a sudden power outage, the hatch may fail to open properly due to the power interruption, resulting in the entrapment of personnel inside and posing a serious safety hazard. For example, the hatch opening and closing support rod device mentioned in patents 202210148450.X and 202410265295.9, although it achieves automated control of the hatch to a certain extent, cannot guarantee the opening mechanism of the hatch in the event of a power outage, and cannot meet the safety requirements in emergency situations. Existing hatch opening devices cannot guarantee that the hatch can be opened by outsiders when power is lost. This may prevent people inside the hatch from escaping in time in an emergency, posing a safety hazard.

[0004] Therefore, a hatch release device was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a hatch release device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: The canopy release device includes a physiotherapy chamber body, on which a canopy is hinged at the top and bottom. A lower fixed bracket is fixedly installed on the frame of the physiotherapy chamber body, and an electric push rod is hinged on the lower fixed bracket. An electromagnetic lock is provided on the canopy, and a U-shaped lock is hinged to the end of the electric push rod, with the U-shaped lock located inside the electromagnetic lock.

[0007] Furthermore, the top surface of the physiotherapy chamber is provided with a through groove, and the electric push rod is located in the through groove. The extension and retraction of the electric push rod is used for the opening and closing operation of the chamber cover and the physiotherapy chamber.

[0008] Furthermore, the electromagnetic lock includes a mounting bracket fixedly installed on the inner wall of the hatch, and an electromagnetic lock frame is mounted on the surface of the mounting bracket, and a locking block is fixedly installed on the electromagnetic lock frame, with a slot opened on the surface of the locking block.

[0009] Furthermore, a cavity is provided on one side wall of the slot of the locking block, and a stepped lever is movably inserted into the cavity. A spring is sleeved on the surface of the stepped lever, and the two ends of the spring are fixedly connected to the end face of the stepped lever and one end face of the cavity, respectively. An electromagnet is embedded in the other side wall of the slot of the locking block.

[0010] Furthermore, the electromagnet and the stepped lever are arranged coaxially.

[0011] Furthermore, when not in use due to power failure, the electromagnet is energized, and the end of the step lever is tightly attached to the electromagnet under the action of magnetic force. The step lever is inserted into the U-shaped lock, and the spring is compressed at this time.

[0012] The beneficial effects of this utility model are as follows: The cover is hinged to the top of the physiotherapy chamber and can rotate around the hinge point to open and close. The lower fixed bracket is fixed to the frame of the physiotherapy chamber, providing a stable mounting base for the electric push rod.

[0018] like Figures 1 to 5 As shown, the canopy release device includes a physiotherapy chamber 1, a canopy 2 hinged to the top and bottom of the physiotherapy chamber 1, a lower fixed bracket 3 fixedly installed on the frame of the physiotherapy chamber 1, an electric push rod 4 hinged to the lower fixed bracket 3, an electromagnetic lock 5 provided on the canopy 2, and a U-shaped lock 6 hinged to the end of the electric push rod 4, and the U-shaped lock 6 is located inside the electromagnetic lock 5; like Figures 3 to 5 As shown, specifically, the electromagnetic lock 5 includes a mounting bracket 501 fixedly installed on the inner wall of the hatch 2, and an electromagnetic lock bracket 502 is installed on the surface of the mounting bracket 501, and a locking block 503 is fixedly installed on the electromagnetic lock bracket 502, with a slot on the surface of the locking block 503.

[0019] More specifically, the mounting bracket 501 is fixed to the inner wall of the hatch 2 as the entire base, and the electromagnetic lock bracket 502 is fixed on the mounting bracket 501. The interior of the electromagnetic lock bracket 502 is used to install the locking block 503, and the slots on its surface are used to accommodate and lock the dynamic U-shaped lock 6.

[0020] like Figure 4 and Figure 5 As shown, in some practical applications, a cavity 504 is provided on one side wall of the slot of the locking block 503, and a stepped connecting rod 505 is movably inserted into the cavity 504. A spring 506 is sleeved on the surface of the stepped connecting rod 505, and the two ends of the spring 506 are fixedly connected to the end face of the stepped connecting rod 505 and one end face of the cavity 504, respectively. An electromagnet 507 is embedded in the other side wall of the slot of the locking block 503.

[0021] More specifically, the step lever 505 is movably inserted into this cavity 504 and can slide within it. The spring 506 provides an elastic thrust to the step lever 505 toward the outside of the lock. On the other side wall of the slot, an electromagnet 507 is embedded. The extension and retraction of the step lever 505 in the cavity 504 is achieved by turning the electromagnet 507 on and off, thereby locking and releasing the U-shaped lock 6.

[0022] like Figure 4 and Figure 5 As shown, in some practical applications, the electromagnet 507 and the stepped lever 505 are coaxially aligned.

[0023] More specifically, the central axis of electromagnet 507 is coaxial with the axis of movable step lever 505, ensuring that when electromagnet 507 is energized and generates magnetic force, its attraction can act on the end face of step lever 505 along the most efficient path, so that it overcomes the elastic force of spring 506 and moves in the direction of electromagnet 507, thereby achieving stable and reliable attraction and locking.

[0024] In some practical applications, when the power is not interrupted, the electromagnet 507 is energized, the end of the step lever 505 is tightly attached to the electromagnet 507 under the action of magnetic force, and the step lever 505 is inserted into the U-shaped lock 6. At this time, the spring 506 is in a compressed state.

[0025] More specifically, when electromagnet 507 is energized, it generates electromagnetic attraction, firmly attracting the end of step lever 505, making it adhere tightly to the surface of electromagnet 507. At this time, the other end of step lever 505 overcomes the elastic force of spring 506 and moves outward, inserting into U-shaped lock 6 to form a mechanical interlock, locking hatch 2. At this time, spring 506 is in a compressed, energy-storing state. Electromagnet 507 immediately loses power, and the electromagnetic force generated by electromagnet 507 disappears instantly. The elastic force of compressed spring 506 is released, pushing step lever 505 to move rapidly inward, causing its end to exit from U-shaped lock 6, thereby releasing the mechanical interlock. At this time, even if electric push rod 4 cannot work due to power failure, outside personnel can directly and manually open hatch 2, realizing the emergency release function in the event of power failure and ensuring the safety of personnel inside the cabin.

[0026] In some practical applications, the top surface of the physiotherapy chamber 1 is provided with a through groove, and the electric push rod 4 is located in the through groove. The extension and retraction of the electric push rod 4 is used for the opening and closing operation of the chamber cover 2 and the physiotherapy chamber 1.

[0027] More specifically, when an instruction to open the cover is received, the push rod of the electric push rod 4 extends outward, and pushes the U-shaped lock 6 that is hinged to it, thereby opening the cover 2 by rotating it around the hinge point. When it is necessary to close the cover, the push rod of the electric push rod 4 retracts, and the U-shaped lock 6 pulls the cover 2 to close it.

[0028] In summary: The cover 2 is hinged to the top of the physiotherapy chamber 1 and can rotate around the hinge point to open and close. The lower fixed bracket 3 is fixed to the frame of the physiotherapy chamber 1, providing a stable mounting base for the electric push rod 4. The cylinder end of the electric push rod 4 is hinged to the lower fixed bracket 3, and its telescopic end is hinged to the U-shaped lock 6. The electromagnetic lock 5 is installed on the inside of the cover 2. Under normal use, the U-shaped lock 6 will enter the locking port of the electromagnetic lock 5 and be locked when the electromagnetic lock 5 is energized. The cover 2 and the physiotherapy chamber 1 are powered by the extension and retraction of the electric push rod 4 to open and close the cover 2. When there is a power outage, the electromagnetic lock 5 is de-energized and in the open state, which can release the U-shaped lock 6 after the power is cut off, and the cover 2 and the physiotherapy chamber 1 can be opened manually.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
