Description

Technical Field

[0001] The utility model relates to a releasing device, in particular to a manual releasing device suitable for kitchen fire fighting equipment. Background Art

[0002] At present, for kitchen fire extinguishing systems, they are all equipped with fuse devices. In this way, when high temperature is reached or the fire is in the initial stage, the triggering device of the fire extinguishing device can be activated by the fusing of the fuse device. At present, the conventional fuse devices are electronic valves controlled by temperature sensors and physical temperature sensing strips. The implementation cost of electronic valves is high, so temperature sensing strips are mainly used.

[0003] The commonly used fusing device is to tie iron wires at both ends of the temperature sensing strip. The iron wire at one end is relatively fixed, and the iron wire at the other end is connected to the firing device to form a trigger wire. When a high temperature warning is triggered, the temperature sensing strip melts, and the trigger wire switches from a tight state to a released state, thereby allowing the firing device to fire.

[0004] The current temperature sensing strip needs to be baked at high temperature for a long time before it can be fused. In order to enable timely manual intervention under the premise of discovering a possible fire, a manual control component is often added to the firing device.

[0005] At present, the commonly used manual control components are just an extra steel wire extending outward from the firing device, and a pull ring is tied to the steel wire. By holding the pull ring and pulling the steel wire, the effect of manually triggering the firing device is achieved. Such a structure is prone to false triggering due to the touch of the steel wire during layout and maintenance. In addition, if the personnel apply too much force due to nervousness, it is easy to cause the pull ring to fly off, affecting the gripping force. Furthermore, in order not to affect the response of the firing device, the existing steel wire needs to be in a taut state, and a clamping ring is often added to the extended end where the steel wire is connected to the firing device. Due to different pulling angles, the steel wire may be stuck on the clamping ring.

[0006] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a manual release device suitable for kitchen fire protection equipment to make it more valuable for industrial use. Utility Model Content

[0036] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] like Figures 1 to 2 The manual release device for kitchen fire fighting equipment includes a mounting plate 1, which is different from the others in that: a plurality of positioning holes are provided on the mounting plate 1, and positioning screws 2 are provided in the positioning holes. In this way, the utility model can be conveniently installed on a wall or a control box in a kitchen space. At the same time, considering the need for traction and guidance, a guide assembly is provided at the upper end of the mounting plate 1, and a traction assembly is inserted into the guide assembly. In addition, in order to facilitate the user to grip and apply force more conveniently during use, a grip assembly is provided at the lower end of the traction assembly. Furthermore, in order to facilitate misoperation and achieve appropriate insurance, a temporary positioning assembly is configured on the grip assembly.

[0038] In combination with a preferred embodiment of the utility model, the guide assembly includes a guide outer tube 3 located at the upper end of the mounting plate 1, and a guide inner tube 4 is inserted into the guide outer tube 3. At the same time, considering the stability of the combination, the guide inner tube 4 is threadedly connected to the guide outer tube 3. In this way, through the existence of the guide outer tube 3, a preliminary guide can be provided for the direction of the traction assembly. Through the guide inner tube 4, the final stable guidance of the traction assembly is achieved to avoid excessive angle deviation and affect the subsequent pulling release. In addition, in order to reduce the contact friction between the traction assembly and the guide inner tube 4, the guide inner tube 4 can be made of ceramic material. Furthermore, the upper end of the guide inner tube 4 extends out of the guide outer tube 3, and the upper end of the guide inner tube 4 is provided with an expansion port 5. In this way, in the subsequent release process, even if the traction assembly shakes, it can be restricted by the expansion port 5, which is convenient for the traction assembly to pull the control wire connected to it more stably without excessive left and right vibration. In the event of an emergency fire, even if the user fails to apply vertical downward force smoothly and a horizontal pull occurs, the guide assembly can be used to guide the steel wire to be pulled and displaced.

[0039] Further, in order to achieve stable force transmission, the traction assembly used in the utility model includes a traction steel wire 6, and a winding ring 7 is provided at the upper end of the traction steel wire 6 located at the guide assembly. In this way, the external control steel wire can be bound to the winding ring 7, which is convenient for controlling the movement stroke of the control steel wire through the traction steel wire 6, and is convenient for subsequent release intervention. At the same time, a stop assembly is provided at the lower end of the traction steel wire 6 located at the guide assembly. In this way, the traction steel wire 6 can be kept in a standby state and the control steel wire can be kept in a proper tight state. Specifically, the stop assembly used includes a stop baffle 8 inserted on the traction steel wire 6, the diameter of the stop baffle 8 is larger than the diameter of the lower end opening of the guide assembly, and the traction steel wire 6 is provided with a limit buckle 9 at the lower end of the stop baffle 8. In this way, when the assembly is completed and the debugging is completed, the limit buckle 9 is completely wound and fixed to the traction steel wire 6. In this way, the stop baffle 8 is fixed. Under the obstruction of the stop baffle 8, the traction steel wire 6 will not move forward, ensuring that the control steel wire connected thereto is tight in place.

[0040] In view of the actual implementation, considering the convenience of holding and applying force, the holding assembly includes a force-applying cross bar 10, the force-applying cross bar 10 is connected to the traction assembly, a holding ring 11 is provided on the force-applying cross bar 10, and a temporary positioning assembly is provided at one end of the force-applying cross bar 10. Specifically, a threading sleeve 12 connected to the traction assembly is provided on the force-applying cross bar 10, and the tail section of the traction assembly is wrapped and locked on the threading sleeve 12. In this way, it is ensured that the traction wire 6 can be firmly combined with the force-applying cross bar 10. In addition, reinforcement blocks 13 are provided at the junctions of the two ends of the force-applying cross bar 10 and the holding ring 11. Therefore, even if excessive force is applied during use, it can be ensured as much as possible that the holding ring 11 will not loosen from the force-applying cross bar 10.

[0041] Going further, in order to assist the stop assembly in temporary locking and avoid false triggering during daily cleaning contact, the temporary positioning assembly includes a limit ring 14 connected to the grip assembly, and a socket is provided at the corresponding position of the mounting plate 1, and a plug post 15 is inserted in the limit ring 14 and the socket. In this way, under the restriction of the plug post 15, the stress caused by the simple force applied to the grip ring 11 is mainly borne by the plug post 15, and will not be excessively transferred to the traction wire 6. For this reason, the control wire will not be triggered to move abnormally. In addition, considering that the plug post 15 can be quickly released during use, a pulling ring 16 can be provided at the outer end of the plug post 15. In this way, when a fire occurs, the pulling ring 16 can be grasped to loosen the plug post 15, which is convenient for pulling the grip ring 11.

[0042] The working principle of the utility model is as follows:

[0043] When it is needed, the user pulls out the plug 15. Then, pull the grip ring 11 downward or outward. At the same time, the traction wire 6 and the control wire begin to retreat. In this way, the piercing device connected to the end of the control wire is pulled and fired, and begins to pierce the tank containing the fire extinguishing medium, entering the fire extinguishing stage.

[0044] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

[0045] 1. Through the existence of the guide component, the user can pull it downward or outward at a certain angle during use, which can make the traction component achieve a smooth and overall downward displacement, ensuring that the control wire connected to it is triggered in time and there will be no interactive vibration and deflection.

[0046] 2. The traction component and the holding component cooperate with each other to realize convenient pulling triggering, and the traction component itself is provided with a stop component, which will not loosen after being adjusted in place, ensuring that the control wire connected to it is in a moderately tight state.

[0047] 3. Equipped with a temporary positioning component to avoid false triggering during daily maintenance and cleaning.

[0048] 4. It can be adapted to the current conventional kitchen fire fighting equipment that uses control wire as the trigger medium to meet the needs of manual emergency release when the fuse is not in the blown state.

[0049] 5. The overall structure is simple, easy to manufacture and use.

[0050] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure.
