Abstract
Description
Technical Field

[0002] For the existing kitchen fire protection system, whether it uses a fuse or an electronic valve, a linear medium such as a traction wire is used to release and control the tank firing device. For the layout of the traction wire, in order to avoid the release effect, it is often necessary to bypass various obstacles from the wall and top pipes in the kitchen, such as smoke alarms and control switches. For this reason, the traction wire needs to be properly turned.
[0003] At present, the conventional steering method is to set nails on the contact surface and let the traction wire turn around the nails. However, this method is not convenient for adjusting the tension of the traction wire during wiring, which is easy to cause false triggering. At the same time, if there are multiple turns in a short distance, it will often cause the traction wire to get stuck.
[0004] In the prior art, a section of pipeline is installed on the outer sleeve of the traction wire, and nails are fixed on the pipeline to fix the pipeline to the joint surface such as the wall. However, the pipeline is a vertical structure, and the end of the traction wire that turns is easy to cut the pipeline mouth when released, causing it to be embedded in the cut end surface, and the defect of getting stuck may still occur. In addition, when the traction wire is in a taut state, there may also be displacement interference at the contact points between it and the two ends of the pipeline mouth.

[0037] 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.
[0038] like Figures 1 to 4 The invention discloses a traction wire steering guide device for kitchen fire protection system, which includes a steering elbow, and is different in that a wiring channel is arranged in the steering elbow, which is convenient for non-destructive deflection guidance of the traction wire. At the same time, both ends of the steering elbow are provided with a limiting mechanism, and the limiting mechanism is connected with the wiring channel. In this way, after the traction wire is put in place, it can be properly restrained to avoid unnecessary axial swing of the traction wire after installation. Moreover, the temporary locking of the traction wire in sections during the debugging period can be met, which is convenient for the planning of the routing and release of the traction wire. Considering the needs of the wiring layout, a wiring space is arranged in the limiting mechanism, a locking cap is arranged on the limiting mechanism, and a wire passing hole is arranged on the locking cap. In this way, the traction wire is in a free travel or a relatively fixed state through the tightness of the locking cap. Considering the appropriate steering guidance during installation, an expansion fin is arranged at the bend of the steering elbow, and a positioning hole is arranged on the expansion fin, and a positioning bolt is penetrated in the positioning hole. When it is necessary to realize movable steering conversion, there is a movable gap between the positioning bolt and its joint surface (during the safety period, the positioning bolt is not completely fixed), so that the steering elbow can be adjusted up and down like a seesaw with the positioning bolt as the axis point.
[0039] In combination with a preferred embodiment of the present invention, considering the need for conventional routing, the bending angle of the steering elbow is 15 to 60 degrees, which can meet the required angle of obstacle avoidance. In addition, in combination with the top routing planning in most cases, the main purpose is to avoid the space occupied by the range hood and the possible spray pipe. For this reason, the bending angle of the steering elbow is 45 degrees, which is a more optimal choice.
[0040] Furthermore, the wiring channel is located at the intersection of the steering bend and has a space for expansion. In this way, when some traction wires with larger diameters pass through, even if they are bulged by external stress, there is a certain amount of space to avoid the defect of getting stuck at the intersection.
[0041] For the application of traction wires with larger diameters: the limiting mechanism adopted by the utility model includes a limiting ring connected to the steering elbow, and the limiting ring is provided with a number of ring-shaped binding strips facing outward, and the middle of the binding strips constitutes a wiring space. At the same time, a locking cap is provided on the outer sleeve of the binding strip, and the bottom of the locking cap is interference fit with the limiting ring, and the wiring space corresponds to the position of the wire hole. During the wiring, the traction wire is first passed through the locking cap, and then inserted into the wiring space. Moreover, when the locking cap is not completely clamped, the traction wire can be displaced in the wiring space, which is convenient for free movement during wiring debugging. In this way, the wiring adjustment needs of large-diameter traction wires can be met. After the debugging is completed, press the locking cap to make it in an interference fit state. At this time, the binding strip will be pressed and move inward, just squeezing the traction wire to achieve locking.
[0042] For the application of traction wires with smaller diameters: the limiting mechanism adopted by the utility model can also include a contact ring connected to the steering elbow, a lead-wire boss is provided on the contact ring, and a threading hole is provided in the lead-wire boss. At the same time, a main thread is provided on the outside of the contact ring, and a corresponding secondary thread is provided on the inner wall of the locking cap. The locking cap is threadedly connected to the contact ring, and the threading hole corresponds to the position of the threading hole. In this way, the traction wire is first passed through the locking cap, and then the lead-wire boss is inserted. When the locking cap is not completely tightened, the traction wire has a free adjustment stroke. When the debugging is completed, tighten the locking cap, the inner wall of the locking cap squeezes the lead-wire boss, and then the threading hole is deformed under pressure, and it also shrinks, and then the traction wire is stuck. In this way, some traction wires with smaller diameters can be met, and convenient threading guidance and pre-positioning are convenient during debugging.
[0043] Going further, in order to bear the external stress applied after the positioning bolts are connected and avoid concentrated force on a certain point of the extended fin, the extended fin is arc-shaped. At the same time, for applications that require the steering elbow to rotate appropriately around the positioning bolts, in order to achieve smooth rotation, a bearing assembly (not shown in the figure) can be provided in the positioning hole, and the positioning bolt passes through the bearing assembly. In this way, the positioning bolt only serves to relatively connect the steering elbow with the joint surface such as the wall, wiring bracket, etc. After installation, it does not affect the rotation of the traction wire connected to the steering elbow.
[0044] At the same time, the locking cap is provided with an anti-skid mechanism, which is a plurality of anti-skid strips distributed in an array. In this way, during wiring and debugging, it is more convenient to grasp with fingers, and it is convenient to perform corresponding locking and unlocking operations without the need for specific tools to coordinate the operation.
[0045] Furthermore, the utility model is provided with a marking layer outside the steering elbow, so that the preset type of the limiting mechanism can be marked, and the diameter range of the adapted traction wire can be adapted, so that the user can quickly identify and select according to the needs.
[0046] The working principle of the utility model is as follows:
[0047] Insert the traction wire into the steering elbow after passing through the locking cap in a certain order. Guided by the wiring channel, the traction wire is bent at a certain angle. In this way, obstacles such as smoke alarms and temperature sensors that may affect the movement of the traction wire in the wiring path are bypassed. At the same time, the corner layout required for wiring can also be met, making it easier to connect the traction wire with the tank release device in the kitchen fire protection system. In order to avoid the influence of rust, the steering elbow can be preferably made of PC or PP material.
[0048] When the temperature sensing piece connected to the traction wire melts or the connected temperature control valve is released, the traction wire loses the stress pull at one end (the left end) and is released. Figure 3 The tense state entered Figure 4 That is to say, the steering elbow can carry the traction wire around the positioning bolt to make moderate steering.
[0049] During this period, the steering elbow rotates around the positioning bolt to ensure that the traction wire has a release stroke and will not get stuck. At the same time, this released stroke is just used to realize the firing stroke of the corresponding tank release device in the kitchen fire protection system. In this way, the corresponding fire protection tank is fired to output the corresponding foam or gas.
[0050] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:
[0051] 1. It can make the traction wire under moderate tension, and the steering layout of the complete traction angle can meet the obstacle avoidance needs in the kitchen without blocking the movement of the traction wire.
[0052] 2. The steering elbow can cooperate with the traction wire to rotate appropriately to meet the release stroke requirements of the traction wire without getting stuck.
[0053] 3. It is equipped with expansion space to facilitate the turning of the traction wire and will not block the wiring channel and affect its movement.
[0054] 4. The tightness of the locking cap can be adjusted to adjust the tightness of the traction wire and the steering elbow, which is convenient for debugging and wiring.
[0055] 5. Bearing components can be added to facilitate better tilting and rotation of the steering elbow.
[0056] 6. It can ensure that the release stroke is not affected when the traction wire turns, and the release response speed is fast.
[0057] 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. Therefore, they cannot be understood as a limitation on the present invention.
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
