Description

Technical Field

[0001] This utility model relates to a docking device, and more particularly to a wire rope anti-detachment docking device suitable for kitchen fire extinguishing systems. Background Technology

[0002] For current kitchen fire suppression systems, the primary triggering mechanism is the melting of a heat-sensing fin, which opens the heat-sensing shear, causing the steel wire rope connected to it to loosen. The release of the steel wire rope then releases components such as the gas valve attached to it.

[0003] Due to the different specifications of various temperature sensors or release mechanisms, complex cutting and splicing of wire ropes are often required during system layout. Because of the different models of release tanks, an additional length needs to be reserved in the docking and binding area. If personnel lack experience, this can easily affect the tension of the wire rope, thus impacting the final release response.

[0004] Previously, the applicant had also developed a simple quick-connect wire rope device. However, in actual use, the meshing gap was fixed, and the adjustment range was limited. For wire rope layouts in single-tank release devices that require precise adjustment of the release gap, improper triggering or delayed firing may occur. Furthermore, for multi-tank release devices, excessive tensile stress can cause improper skew of the simple quick-connect wire rope device, affecting the transmission of release stress through the wire rope. Additionally, during setup, abnormal "self-cutting" of the wire rope's tightened end may occur.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a steel wire rope anti-detachment docking device suitable for kitchen fire extinguishing systems, making it more industrially valuable. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a wire rope anti-detachment docking device suitable for kitchen fire extinguishing systems.

[0007] This utility model discloses a wire rope anti-detachment docking device suitable for kitchen fire extinguishing systems, comprising a device body, wherein: the device body includes a bearing rod, the front end of the bearing rod is provided with an arc-shaped coiled storage ring, the front end of the coiled storage ring extends into a limiting strip, the limiting strip is distributed in close contact with the bearing rod, and several positioning mechanisms are distributed on the outer side of the limiting strip. When two device bodies are docked, the bearing rod and the limiting strip are covered with a heat-shrinkable positioning sleeve, and a locking component is wrapped around the heat-shrinkable positioning sleeve.

[0008] Furthermore, in the aforementioned anti-detachment docking device for steel wire ropes suitable for kitchen fire extinguishing systems, the inner side of the coiled storage ring extends with an anti-detachment protrusion.

[0009] Furthermore, in the aforementioned anti-detachment docking device for steel wire ropes applicable to kitchen fire extinguishing systems, the positioning mechanism consists of protrusions that are evenly distributed among each other.

[0010] Furthermore, in the aforementioned anti-detachment docking device for steel wire ropes suitable for kitchen fire extinguishing systems, the heat-shrinkable positioning sleeve is filled with bonding adhesive.

[0011] Furthermore, in the aforementioned anti-detachment docking device for steel wire ropes suitable for kitchen fire extinguishing systems, the locking component is made of iron wire.

[0012] Furthermore, in the aforementioned anti-detachment docking device for steel wire ropes suitable for kitchen fire extinguishing systems, the surface of the device body is coated with a rubber anti-slip layer.

[0013] By means of the above solution, this utility model has at least the following advantages:

[0014] 1. When laying out the system wire rope, two wire ropes can be connected to form a whole to prevent derailment, as needed.

[0015] 2. During use, as long as the wire rope is properly secured, it will not come loose unexpectedly. It can be further secured by the anti-loosening protrusions.

[0016] 3. It is equipped with an independent coiling and storage ring to bear the tension stress of the wire rope, so that the stress concentration at the joint of the two wire ropes will not cause "self-cutting".

[0017] 4. It can meet the docking requirements between transmission wire ropes, or between the release wire rope of the tank and the transmission wire rope.

[0018] 5. The overall structure is simple and easy to use, meeting the docking requirements of wire rope transmission systems in current conventional kitchen fire extinguishing systems.

[0019] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. Attached Figure Description

[0020] Figure 1 This is a schematic diagram of the device body.

[0021] Figure 2 This is a schematic diagram of the docking and wire rope connection of this utility model.

[0022] The meanings of the labels in the figures are as follows.

[0023] 1. Support rod 2. Curled storage ring

[0024] 3 Limiting strips 4 Anti-slip protrusions

[0025] 5. Protrusions 6. Heat-shrink positioning sleeve

[0026] 7. Iron wire 8. Steel wire rope Detailed Implementation

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] like Figures 1 to 2 A wire rope anti-detachment docking device suitable for kitchen fire extinguishing systems includes a device body, which is unique in that: the device body includes a support rod 1, and the front end of the support rod 1 is provided with an arc-shaped coiled storage ring 2. This facilitates the attachment of one end of the wire rope 8 to the coiled storage ring 2 for positioning of the wire rope 8 end. At the same time, the front end of the coiled storage ring 2 extends a limiting strip 3, which is distributed along the support rod 1 to prevent the end of the wire rope 8 from loosening. Furthermore, several positioning mechanisms are distributed on the outer side of the limiting strip 3 to increase the friction with the locking component during subsequent docking, achieving a more stable connection. During use, when the two device bodies are docked, the support rod 1 and the limiting strip 3 are covered with a heat-shrinkable positioning sleeve 6 for auxiliary positioning. Furthermore, a locking component is wrapped around the heat-shrinkable positioning sleeve to achieve final locking.

[0029] In a preferred embodiment of this invention, an anti-detachment protrusion 4 extends from the inner side of the coiled storage ring 2. Thus, even if slight slippage occurs while the end of the wire 7 is secured, the anti-detachment protrusion 4 provides adequate protection, preventing the sleeve-like structure at the end of the wire 7 from loosening outwards from the coiled storage ring 2.

[0030] Looking further, the positioning mechanism consists of protrusions 5, evenly spaced together, and the locking component is wire 7. As the wire 7 tightens, it causes the heat-shrinkable positioning sleeve 6 to embed into the grooves distributed between the protrusions 5. Relying on the restraint of the protrusions 5, the wire 7 will not loosen from the grooves. With the subsequent use of multiple wires 7 for winding, an effective locking connection between the two device bodies is achieved.

[0031] In practical implementation, to effectively cope with the large stress impact transmitted, adhesive (not shown in the figure) can be potted inside the heat-shrinkable positioning sleeve 6. In this way, effective adhesive-assisted positioning can be achieved after the joint is completed.

[0032] Furthermore, the surface of the device body is coated with a rubber anti-slip layer (not shown in the figure). This increases the bonding friction when the two ends of the device body are joined back to back, reducing displacement and preventing loosening during subsequent heat-shrink positioning.

[0033] The working principle of this utility model is as follows:

[0034] In Example 1, the fire extinguishing equipment subsequently connected to the steel wire rope 8 is a single-tank type, which requires a relatively small stress to be activated.

[0035] The two device bodies are brought into back-to-back contact to achieve proper pre-positioning. During this process, adhesive can be applied to the joint area. Then, the heat-shrinkable positioning sleeve 6 is fitted into the middle of the device body, ensuring that the support rod 1 and the limiting strip 3 are both within the heat-shrinkable positioning sleeve 6.

[0036] Bring a heat source such as a lighter close to the heat-shrinkable positioning sleeve 6, causing it to shrink and adhere tightly to the two device bodies. Then, wrap the wire 7 around the outside of the heat-shrinkable positioning sleeve 6. At this point, due to the heat shrinking process, the heat-shrinkable positioning sleeve 6 will exhibit an anti-slip protrusion 4 structure. Wrap the wire 7 around the groove formed between the anti-slip protrusions to achieve a locking effect.

[0037] Finally, thread the corresponding end of the steel wire rope 8 into the coiled storage ring 2 and tighten it.

[0038] In Example 2, the fire extinguishing equipment subsequently connected to the steel wire rope 8 is a multi-tank mixed spray assembly, which requires a large stress to be activated.

[0039] The two device bodies are brought into back-to-back contact to achieve proper pre-positioning. Then, the heat-shrinkable positioning sleeve 6 is fitted into the middle of the device body, ensuring that the bearing rod 1 and the limiting strip 3 are both within the heat-shrinkable positioning sleeve 6.

[0040] Next, a bonding adhesive is filled into the heat-shrinkable positioning sleeve 6. During the curing of the adhesive, the heat-shrinkable positioning sleeve 6 is gently squeezed to expel air bubbles.

[0041] After the colloid has completely solidified, wrap the wire 7 around the heat-shrinkable positioning sleeve 6 to achieve auxiliary locking.

[0042] Of course, the device body can be pre-installed before the wire rope 8 leaves the factory as needed, so that the length of the wire rope 8 can be cut on site according to the actual wiring needs and quickly connected.

[0043] During use, the two device bodies are connected and pulled by their respective steel wire ropes 8, maintaining a moderate tension and preventing abnormal separation between them. In this way, the release stress transmitted from the melting of the fusing device can be quickly transferred to the tank equipment through this invention, facilitating its firing.

[0044] The only thing to note is that after the installation of this utility model is completed, it needs to be 30 centimeters away from the steel wire rope 8 inlet hole on the outside of the tank to ensure that sufficient release stroke of the steel wire rope 8 is reserved.

[0045] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0046] 1. When laying out the system wire rope, two wire ropes can be connected to form a whole to prevent derailment, as needed.

[0047] 2. During use, as long as the wire rope is properly secured, it will not come loose unexpectedly. It can be further secured by the anti-loosening protrusions.

[0048] 3. It is equipped with an independent coiling and storage ring to bear the tension stress of the wire rope, so that the stress concentration at the joint of the two wire ropes will not cause "self-cutting".

[0049] 4. It can meet the docking requirements between transmission wire ropes, or between the release wire rope of the tank and the transmission wire rope.

[0050] 5. The overall structure is simple and easy to use, meeting the docking requirements of wire rope transmission systems in current conventional kitchen fire extinguishing systems.

They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
