Description

Technical Field

[0001] This utility model relates to the technical field of constant temperature suspended fire extinguishing devices, specifically a constant temperature suspended fire extinguishing device. Background Technology

[0002] The constant-temperature suspended fire extinguishing device is an automatic fire extinguishing device that does not require an external power supply or complex piping network. It releases extinguishing agent when triggered by a temperature sensing element during a fire. It is suitable for rapid fire extinguishing in small enclosed spaces. Its triggering mechanism is that the device has a built-in glass bulb or fusible alloy as a temperature sensing element. When the ambient temperature reaches the preset value, the glass bulb breaks or the fusible alloy melts, triggering the valve to release the extinguishing agent. Some models add an electromagnetic device to the temperature sensing element to improve the response speed and accuracy, but require an external power supply.

[0003] In the current technology, the constant temperature suspended fire extinguishing device is composed of an auxiliary structure module and a core functional module. The core functional module is composed of a temperature-sensing activation component, a fire extinguishing agent storage unit, and a release component. The auxiliary structure module is composed of suspension and fixing components. The fixing components are composed of a support with a metal hook or a connecting cylinder, and the suspension components are a hanging ring or a metal column. In actual installation, if a movable hook is used, with the hanging ring attached to the metal hook, the extinguishing device is triggered, and the bottom sprays extinguishing agent, resulting in a reverse force on the extinguishing device. This causes the extinguishing device to sway on the metal hook, the nozzle direction to deviate, and the extinguishing agent coverage to be inaccurate, affecting the extinguishing effect. If a fixed hook is used, after inserting the metal column into the connecting cylinder, it is fixed by bolts through the metal column and the connecting cylinder. The weight of the device and the spray reaction force are concentrated in the bolt holes of the connecting cylinder, causing a sudden increase in local stress in the bolt holes, resulting in deformation of the bolt holes. Subsequent disassembly of the metal column and bolts is difficult, affecting the replacement of the device. Therefore, a constant temperature suspended extinguishing device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a constant-temperature suspended fire extinguishing device, which has the advantages of stable installation and stress dispersion. It solves the problems of movable hanging, where the hanging ring is attached to the metal hook, and when the fire extinguishing device is triggered, the bottom of the device sprays extinguishing agent, which exerts a reverse force on the fire extinguishing device, causing it to sway on the metal hook, the nozzle direction to deviate, and the extinguishing agent coverage to be inaccurate, thus affecting the fire extinguishing effect; and fixed hanging, where the metal column is inserted into the connecting tube and fixed with bolts through the metal column and connecting tube, the weight of the device and the spray reaction force are concentrated in the bolt holes of the connecting tube, causing a sudden increase in local stress in the bolt holes of the connecting tube, causing deformation of the bolt holes, and making subsequent disassembly of the metal column and bolts difficult.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a constant temperature suspended fire extinguishing device, comprising a constant temperature fire extinguishing device, wherein a suspension component is provided on the constant temperature fire extinguishing device, a fixing component for connecting to the ceiling is provided on the suspension component, and a locking component for locking the suspension component is provided on the fixing component. The suspension component includes a connecting column section, one end of which is fixedly connected to the constant temperature fire extinguishing device. The other end of the connecting column section is provided with a trapezoidal frustum section, and a square pin section is fixedly installed on the top of the trapezoidal frustum section. The suspension component is an integral structural component. The fixing component includes a fixing plate fixedly connected to the ceiling. A connecting cylinder for connecting the suspension component is fixedly installed at the bottom of the fixing plate. A positioning plate for locking the square pin section is fixedly installed inside the connecting cylinder. Four locking members for supporting the trapezoidal frustum section are slidably installed on the connecting cylinder. The inner inclined surface of the locking member contacts the inclined surface of the trapezoidal frustum section. The locking component is used to restrict the four locking members. A reinforcing ring that contacts the bottom of the locking member is fixedly installed on the outer surface of the connecting cylinder.

[0006] Furthermore, the locking component includes a locking sleeve threaded onto the outer surface of the connecting cylinder, and the inner wall slope of the locking sleeve contacts the outer slope of the four locking components respectively. Two handles are fixedly installed on the outer surface of the locking sleeve.

[0007] Furthermore, the four locking elements are symmetrically distributed around the central axis of the connecting cylinder, with the inner inclined surface of the locking element located inside the connecting cylinder and the outer inclined surface of the locking element located outside the connecting cylinder.

[0008] Furthermore, the connecting cylinder has four rectangular grooves symmetrically arranged around the central axis, and one end of the locking member passes through and extends into the interior of the rectangular groove, with the locking member slidably connected to the rectangular groove.

[0009] Furthermore, four anti-detachment grooves symmetrically arranged around the central axis are provided on the inner peripheral wall of the connecting cylinder, and anti-detachment blocks adapted to the anti-detachment grooves are fixedly installed at the bottom of the four locking components.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This constant-temperature suspended fire extinguishing device achieves dual anti-sway protection—axial limiting and radial fixation—through the integrated suspension component, the positioning plate's snap-fit, and the locking component's support. This prevents the device from shaking during spraying. Furthermore, the inner inclined surface of the locking component fits against the inclined surface of the trapezoidal frustum section, thereby decomposing the device's weight into the locking component's force on the connecting cylinder and the squeezing force on the locking sleeve. In addition, the reinforcing ring supports the bottom of the locking component, dispersing the device's weight and spray reaction force to the entire connecting cylinder, rather than concentrating it in local holes, thus preventing deformation. It does not require through bolts; fixation is achieved through the cooperation of the locking component and the locking parts, making disassembly convenient. 2. This constant temperature suspended fire extinguishing device has a locking sleeve that is connected to the connecting sleeve by a thread. When rotated, the inclined surface of its inner wall can precisely squeeze the locking part to achieve stepless adjustment of locking and controllable fixing strength. The handle provides the operator with a force point, which greatly improves the convenience of locking or disassembling. The threaded connection has self-locking property, which can prevent the locking sleeve from loosening during fire extinguishing and ensure the reliability of fixing. 3. The constant temperature suspended fire extinguishing device has four locking parts symmetrically distributed along the central axis of the connecting cylinder, which are evenly attached to the inclined surface of the trapezoidal frustum section to achieve uniform circumferential force, avoid the device tilting or damage to the locking parts caused by excessive force on one side, and further enhance the anti-sway effect and structural stability.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: Please refer to Figure 1-5 The constant temperature suspended fire extinguishing device in this embodiment includes a constant temperature fire extinguishing device 1, a suspension component 2 on the constant temperature fire extinguishing device 1, a fixing component 3 for connecting to the ceiling on the suspension component 2, and a locking component 4 for locking the suspension component 2 on the fixing component 3.

[0015] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the suspension component 2 includes a connecting column section 21, one end of which is fixedly connected to the constant temperature fire extinguishing device 1, and the other end of the connecting column section 21 is provided with a trapezoidal frustum section 22. A square pin section 23 is fixedly installed on the top of the trapezoidal frustum section 22, and the suspension component 2 is an integral structural component. The fixing component 3 includes a fixing plate 31 fixedly connected to the ceiling. A connecting cylinder 32 for connecting the suspension component 2 is fixedly installed at the bottom of the fixing plate 31. A positioning plate 33 for locking the square pin section 23 is fixedly installed inside the connecting cylinder 32. Four locking members 34 for supporting the trapezoidal frustum section 22 are slidably installed on the connecting cylinder 32. The inner inclined surface of the locking member 34 contacts the inclined surface of the trapezoidal frustum section 22. The locking component 4 is used to limit the four locking members 34. A reinforcing ring 35 that contacts the bottom of the locking member 34 is fixedly installed on the outer surface of the connecting cylinder 32.

[0016] The four locking components 34 are symmetrically distributed around the central axis of the connecting cylinder 32. The inner inclined surface of the locking component 34 is located inside the connecting cylinder 32, and the outer inclined surface of the locking component 34 is located outside the connecting cylinder 32. The four locking components 34 are symmetrically distributed around the central axis of the connecting cylinder 32 and are evenly fitted with the inclined surface of the trapezoidal frustum section 22 to achieve uniform circumferential force. This avoids the device tilting or damage to the locking component 34 caused by excessive force on one side, and further enhances the anti-sway effect and structural stability.

[0017] In addition, four rectangular grooves 321 symmetrically arranged around the central axis are provided on the connecting cylinder 32, and one end of the locking member 34 passes through and extends into the interior of the rectangular groove 321. The locking member 34 is slidably connected to the rectangular groove 321. The rectangular groove 321 provides a clear sliding trajectory for the locking member 34, ensuring that the locking member 34 always moves radially along the connecting cylinder 32 and is precisely matched with the inclined surface of the trapezoidal frustum section 22, avoiding fixation failure or uneven force due to offset.

[0018] It should be noted that four anti-detachment grooves 322 are provided on the inner peripheral wall of the connecting cylinder 32, which are symmetrical about the central axis. The bottom of each of the four locking parts 34 is fixedly installed with an anti-detachment block 341 that is adapted to the anti-detachment groove 322. The anti-detachment block 341 is adapted to the anti-detachment groove 322 and can be engaged to limit the sliding stroke of the locking part 34 and prevent it from coming out of the rectangular groove 321.

[0019] Using the above technical solution, the fixing component 3 is bolted to the ceiling by fixing plate 31. Then, the central axis of the suspension component 2 is aligned with the connecting cylinder 32. The constant temperature fire extinguishing device 1 is pushed upward until the suspension component 2 is inserted into the interior of the connecting cylinder 32, so that the square pin section 23 passes through the positioning plate 33 inside the connecting cylinder 32. The positioning plate 33 locks the square pin section 23 to achieve axial limitation. The locking component 4 squeezes the locking component 34 to slide inward along the rectangular groove 321 until the inner inclined surface of the locking component 34 fits with the inclined surface of the trapezoidal frustum section 22. Thus, the locking component 34 steadily supports the trapezoidal frustum section 22, while the reinforcing ring 35 supports the bottom of the locking component 34 to bear the force.

[0020] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, the locking component 4 includes a locking sleeve 41 threaded onto the outer surface of the connecting cylinder 32, and the inner wall slope of the locking sleeve 41 contacts the outer slope of the four locking components 34 respectively. Two handles 42 are fixedly installed on the outer surface of the locking sleeve 41.

[0021] Using the above technical solution, the operator rotates the locking sleeve 41 counterclockwise by the handle 42, causing it to move upward along the thread on the outer surface of the connecting sleeve 32, releasing the squeezing restriction on the locking part 34, pulling down the constant temperature fire extinguishing device 1, causing the suspension part 2 to move down as a whole, and the locking part 34 slides outward along the rectangular groove 321 under the inclined thrust of the trapezoidal frustum section 22, disengaging from the support of the trapezoidal frustum section 22, and the square pin section 23 disengages from the positioning plate 33, completing the separation of the device from the fixed part 3.

[0022] The working principle of the above embodiments is as follows: During installation, the fixed-temperature suspended fire extinguishing device is installed by bolting the fixing component 3 to the ceiling using the fixing plate 31. Then, the central axis of the suspension component 2 is aligned with the connecting cylinder 32, and the fixed-temperature fire extinguishing device 1 is pushed upward until the suspension component 2 is inserted into the interior of the connecting cylinder 32. This allows the square pin section 23 to pass through the positioning plate 33 inside the connecting cylinder 32, and the positioning plate 33 locks the square pin section 23 to achieve axial limitation. By rotating the handle 42 to lock the sleeve 41, the locking sleeve 41 is controlled to move downward along the outer wall of the connecting cylinder 32. The inclined surface of the inner wall of the locking sleeve 41 presses the locking member 34 to slide inward along the rectangular groove 321 until the inner inclined surface of the locking member 34 is in contact with the inclined surface of the trapezoidal frustum section 22. Thus, the locking member 34 steadily supports the trapezoidal frustum section 22. At the same time, the reinforcing ring 35 supports the bottom of the locking member 34 to bear the force. Thus, the weight of the device is decomposed into the force of the locking member 34 on the connecting cylinder 32 and the squeezing force on the locking sleeve 41 through the locking member 34, so as to disperse the stress. When the constant temperature fire extinguishing device 1 sprays the extinguishing agent and generates a reverse force, the square pin section 23 engages with the positioning plate 33, and the locking part 34 lifts the trapezoidal frustum section 22, thus forming a double positioning to prevent the device from shaking. The reinforcing ring 35 distributes the force borne by the locking part 34 to the entire connecting cylinder 32 to avoid stress concentration. During disassembly and maintenance, the operator rotates the locking sleeve 41 counterclockwise by the handle 42, causing it to move upward along the thread on the outer surface of the connecting sleeve 32, releasing the compression restriction on the locking part 34, and pulling down the constant temperature fire extinguishing device 1, causing the suspension part 2 to move down as a whole. Under the inclined thrust of the trapezoidal frustum section 22, the locking part 34 slides outward along the rectangular groove 321, disengaging from the support of the trapezoidal frustum section 22, and the square pin section 23 disengages from the positioning plate 33, completing the separation of the device from the fixed part 3.
