Description

Technical Field

[0001] This utility model relates to a quick-connect steel wire device, and more particularly to a simple quick-connect steel wire device suitable for kitchen fire extinguishing systems. Background Technology

[0002] For current kitchen fire extinguishing systems, the main triggering method is through the melting of a temperature-sensitive element, which opens the temperature-sensitive shear, thereby loosening the steel wire rope connected to it. The release of the steel wire rope then causes the gas valves and other components connected to it to release.

[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. If the focus is on the length of the wire rope, an additional length needs to be reserved in the docking and binding area. If the personnel lack experience, it can easily affect the tension of the wire rope and the final release response.

[0004] Currently, considering the need to connect different wire ropes, a binding plate is provided, with binding holes at both ends. This allows the ends of two wire ropes to be wound and positioned into the corresponding binding plates. However, this binding method cannot adjust the spacing between the two wire ropes after connection. Users need to estimate the final length to pull or release the wire ropes, often requiring multiple adjustments. Furthermore, if the binding is removed for secondary adjustments after completion, the wire ropes are prone to curling, affecting the final tension.

[0005] Therefore, current methods either involve precisely cutting the steel wire using temperature-sensing plates or making multiple adjustments during the connection process. The former cannot be adjusted according to the actual layout on site, while the latter can affect the tension of the steel wire rope or the load-bearing capacity of the joint end due to repeated binding, easily interfering with subsequent release.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a simple quick-connect steel wire device suitable for kitchen fire extinguishing systems, making it more industrially valuable. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a simple quick-connect steel wire device suitable for kitchen fire extinguishing systems.

[0008] This utility model discloses a simple quick-connect steel wire device applicable to kitchen fire extinguishing systems, comprising steel wire positioning blocks that are connected and interlocked. A locking sleeve is fitted between the steel wire positioning blocks. Each steel wire positioning block includes a bearing block, and the bearing block is provided with several equally spaced locking strips. The spacing between the locking strips is greater than or equal to the thickness of the locking strips. During the connection and interlocking of the upper and lower steel wire positioning blocks, the corresponding locking strips engage with each other. Steel wire threading mechanisms are provided at both the front and rear ends of the bearing block.

[0009] Furthermore, in the aforementioned simple steel wire quick-connect device applicable to kitchen fire extinguishing systems, the locking sleeve includes a rectangular open retaining ring with a surrounding structure, and the ends of the rectangular open retaining ring have mutually fitting connecting pieces, with locking bolts passing through the connecting pieces.

[0010] Furthermore, in the aforementioned simple wire quick-connect device suitable for kitchen fire extinguishing systems, the edge of the locking sleeve is provided with a rounded chamfer.

[0011] Furthermore, in the aforementioned simple quick-connect wire device suitable for kitchen fire extinguishing systems, the cross-section of the locking strip is rectangular.

[0012] Furthermore, in the aforementioned simple quick-connect steel wire device applicable to kitchen fire extinguishing systems, the steel wire threading mechanism is a three-way hole.

[0013] Furthermore, in the aforementioned simple quick-connect steel wire device suitable for kitchen fire extinguishing systems, the inner wall of the three-way hole is provided with a silicone pad layer.

[0031] 9. Steel wire assembly Detailed Implementation

[0032] 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.

[0033] like Figures 1 to 5A simple quick-connect steel wire device suitable for kitchen fire extinguishing systems includes steel wire positioning blocks 1 that connect vertically. This allows a single steel wire positioning block 1 to connect one end of a steel wire, and the connection of the two achieves the interconnection of steel wire assemblies 9. Its unique feature is that, to ensure stability after connection and prevent loosening of the steel wire assembly 9 after tensioning, locking sleeves 2 are fitted between the steel wire positioning blocks 1. Simultaneously, to ensure effective "pair-by-pair" vertical engagement, the steel wire positioning block 1 includes a bearing block 3 with several evenly distributed locking strips 4. Furthermore, to prevent large displacement and jamming after connection, secondary disassembly and reassembly are possible, facilitating on-site adjustment of the final connection spacing to ensure the steel wire assembly 9 is in optimal tension; the spacing between the locking strips 4 is greater than or equal to the thickness of the locking strip 4. Thus, during the vertical connection of the steel wire positioning blocks, the corresponding locking strips 4 engage with each other. Moreover, steel wire threading mechanisms 5 are provided at both ends of the bearing block 3. In this way, the end of the wire assembly 9 can be positioned, which facilitates the tightening and engagement of the wire assembly 9 on the bearing block 3.

[0034] In a preferred embodiment of this invention, to achieve a convenient locking connection similar to a clamp, the locking sleeve 2 includes a rectangular open retaining ring 6 with a surrounding structure. Specifically, the rectangular open retaining ring 6 has mutually fitting connecting pieces 7 at its ends, and a locking bolt 8 passes through the connecting pieces 7. Thus, after the locking bolt 8 is tightened, the locking sleeve 2 has an inward contraction force, preventing displacement of the steel wire positioning blocks 1, especially lateral displacement, allowing the steel wire assembly 9 to be smoothly tightened under tension. This satisfies the requirement for the melting and release of the corresponding temperature sensing element in a kitchen fire extinguishing system. Furthermore, if multiple temperature sensing elements are connected in series on the steel wire assembly 9, multiple locking sleeves 2 can be used to achieve a more stable connection.

[0035] Furthermore, the locking sleeve 2 has rounded chamfers on its edges. This prevents sharp edges from scratching assembly personnel. Simultaneously, the retaining strips 4 distributed on it have rectangular cross-sections. Therefore, when the two wire positioning blocks 1 are engaged, their respective retaining strips 4 can achieve a relatively stable engagement, preventing unnecessary slippage due to the presence of bevels or curvature. Moreover, when the wire assembly 9 is released, the stress released can be effectively transmitted, preventing release failure.

[0036] In practical implementation, the steel wire threading mechanism 5 is a three-way hole. It includes a left hole, a right hole, and a front opening, all three being interconnected. Users can guide the steel wire assembly 9 through the front opening and then secure it around the left and right holes for positioning. Other binding methods can also be used, as long as the steel wire assembly 9 cannot detach from the three-way hole; these will not be elaborated further. Additionally, the openings of the three-way holes are rounded to prevent scratching the steel wire assembly 9. Furthermore, silicone pads can be distributed on the inner walls of the three-way holes. This appropriately increases the friction between the steel wire assembly 9 and the hole, preventing unnecessary slippage and facilitating easier binding and winding positioning.

[0037] The working principle of this utility model is as follows:

[0038] Secure the steel wire assemblies 9 that need to be connected to their corresponding steel wire positioning blocks 1. After securing, pull the steel wire assemblies 9 with moderate force to ensure that they do not slip.

[0039] Next, the two steel wire assemblies 9 are mated together with the surfaces equipped with locking strips 4. During this process, different mating positions can be selected according to subsequent tensioning requirements to achieve either a smaller or larger spacing fit.

[0040] Finally, the locking sleeve 2 is fitted and the locking bolt 8 is used for secondary tightening.

[0041] During the application of this invention, it is important to estimate the entire travel distance of the device to avoid obstruction when the steel wire assembly 9 is released. A 20 cm gap should be maintained between the normal and potential obstruction mechanisms.

[0042] At the same time, the shape of the wire positioning block 1 can be reduced during manufacturing so that it can pass through the release ring.

[0043] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0044] 1. During the layout of the kitchen fire extinguishing system, the wire assemblies, such as release devices and fuse devices, can be quickly and stably connected without the need for precise cutting of the wire assemblies.

[0045] 2. It can meet the requirements of quick docking between components similar to broken steel wires, and through the cooperation between the clips, the spacing of the joint end faces can be finely adjusted. When laying out the corresponding fuse pieces, there is no need for complicated cutting, which facilitates quick layout.

[0046] 3. The two steel wire positioning blocks are tightly connected, which can effectively bear the stress during the tensioning and standby period of the steel wire assembly.

[0047] 4. The wire threading mechanism enables stable winding of the wire assembly ends, eliminating the need for complicated welding for auxiliary locking.

[0048] 5. The overall structure is simple and easy to manufacture and use.

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. Therefore, they should not be construed as limitations on this utility model.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit this 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 this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
