Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a suspended fire extinguishing device. Background Art

[0002] The suspended fire extinguishing device is a common automatic fire extinguishing equipment. When a fire occurs indoors in cooperation with a temperature sensing element, it can actively release the internal fire extinguishing agent, thus playing a role in extinguishing the fire. It is widely used in scenarios such as workshops, warehouses, archives rooms, and power distribution rooms. The patent number ZL 201921462507.3 discloses a suspended heptafluoropropane fire extinguishing device. After the limit disc is inserted into the inner side of the mounting bracket through the through hole, the fire extinguisher body is rotated, and the limit disc is adjusted to be clamped with the limit groove, then the installation of the fire extinguisher body can be completed. By operating in the reverse direction, the fire extinguisher body can be removed. The operation is simple and convenient to use. However, the solution mentioned in the above patent lacks a reliable limit component and has the problem of insufficient stability. When the fire extinguisher sprays the fire extinguishing agent downward, the fire extinguisher generates an upward thrust, causing the limit disc to disengage from the limit groove, resulting in the risk of loosening and detachment.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figures 1 to 6 , an embodiment provided by the present utility model:

[0030] A hanging fire extinguishing device includes a clamping mechanism, a support plate 1, and a fire extinguisher 2 arranged in sequence from top to bottom. The fire extinguisher 2 is suspended on the support plate 1 and is clamped and fixed by the clamping mechanism: a diamond-shaped fixing plate 3 is provided at the top of the fire extinguisher 2; the support plate 1 is provided with a diamond-shaped hole 4 for the fixing plate 3 to pass through, and the diamond-shaped hole 4 matches the shape of the fixing plate 3; the clamping mechanism includes a mounting plate 5 connected above the support plate 1, and an elastically telescopic clamping plate 6 is installed in the middle of the mounting plate 5. The clamping plates 6 are symmetrically distributed about the center line of the diamond-shaped hole 4, and the fixing plate 3 is clamped between the two clamping plates 6; a limiting hole 7 for the fixing plate 3 to insert is provided at the bottom of the clamping plate 6. The limiting hole 7 matches the shape of the fixing plate 3 and is vertically aligned with the diamond-shaped hole 4. The fixing plate 3 is embedded in the limiting hole 7 and is clamped between the support plate 1 and the clamping plate 6.

[0031] The clamping mechanism, the pallet 1, and the fire extinguisher 2 are arranged in sequence from top to bottom. The clamping mechanism is located above the pallet 1, and the fire extinguisher 2 is located below the pallet 1. The fire extinguisher 2 is suspended on the pallet 1 and is fixedly connected by the clamping mechanism, so that the fire extinguisher 2 is fastened to the pallet 1. The fixing plate 3 is located at the top position of the fire extinguisher 2 and has a rhombus structure, and the lengths of the diagonals of the rhombus are inconsistent. The rhombus hole 4 is a through hole, which is opened in the pallet 1 along the up and down direction. The rhombus hole 4 has a rhombus structure and matches the shape of the fixing plate 3. The fixing plate 3 can pass through the rhombus hole 4 from bottom to top. The mounting plate 5 is stacked above the pallet 1 and is fixedly connected to the pallet 1. The middle part of the mounting plate 5 is hollowed out, and two clamping plates 6 are installed inside. The clamping plates 6 can approach and move away from each other. The clamping plates 6 are elastically telescopic, and a return spring 10 is connected between the clamping plates 6 and the mounting plate 5. The clamping plates 6 are symmetrically distributed about the center line of the rhombus hole 4. It can be that the rhombus hole 4 includes a first diagonal and a second diagonal that are perpendicular to each other, the length of the first diagonal is greater than the length of the second diagonal, the center line of the rhombus hole 4 coincides with the first diagonal, and the two clamping plates 6 are symmetrically arranged on both sides of the first diagonal. In the initial state, the two clamping plates 6 are closed to each other, and the return spring 10 is in a relaxed state. When the two clamping plates 6 move away from each other, the return spring 10 is in a compressed state, providing a spring force for clamping for the clamping plates 6, so that the fixing plate 3 is clamped between the two clamping plates 6 to limit the horizontal direction. The limiting hole 7 is located at the bottom of the clamping plate 6 and is opened upward from the bottom of the clamping plate 6. The limiting hole 7 has a half-rhombus structure, matches the shape of the fixing plate 3, and is vertically aligned with the rhombus hole 4. When the two clamping plates 6 are closed to each other, the two limiting holes 7 are combined into a complete rhombus structure and match the shape of the fixing plate 3, and can be sleeved on the outside of the fixing plate 3. The depth of the limiting hole 7 is equal to the thickness of the fixing plate 3. After the fixing plate 3 passes through the rhombus hole 4 from bottom to top, it can continue to move upward and be inserted into the limiting hole 7 until the fixing plate 3 is embedded in the limiting hole 7. The inner side wall of the limiting hole 7 abuts against the outer side wall of the fixing plate 3, and the bottom surface of the limiting hole 7 abuts against the top surface of the fixing plate 3. When the fixing plate 3 rotates in the horizontal direction, the outer side wall of the fixing plate 3 is slidably connected to the inner side wall of the limiting hole 7 and can drive the two clamping plates 6 to approach and move away from each other.

[0032] Working principle:

[0033] In the initial state, the clamping plates 6 are closed to each other, and the limiting holes 7 are vertically aligned with the diamond-shaped holes 4. When it is necessary to install the fire extinguisher 2, align the fixing plate 3 vertically with the diamond-shaped hole 4. The fixing plate 3 passes through the diamond-shaped hole 4 from bottom to top and continues to be inserted upward into the limiting hole 7 until the top surface of the fixing plate 3 abuts against the bottom surface of the limiting hole 7. The fixing plate 3 is embedded in the limiting hole 7. Then, by rotating the fire extinguisher 2, the fixing plate 3 rotates in the limiting hole 7, and the rotation angle can be 90 degrees, so that the fixing plate 3 is misaligned with the limiting hole 7 and the diamond-shaped hole 4, and the fixing plate 3 cannot disengage downward from the diamond-shaped hole 4. Finally, the fixing plate 3 is suspended above the support plate 1. The fixing plate 3 is between the top surface of the support plate 1 and the bottom surface of the limiting hole 7, and the two clamp the fixing plate 3 to achieve vertical direction limiting. In addition, under the push of the fixing plate 3, the clamping plates 6 move away from each other, and the return spring 10 is in a compressed state. The two clamping plates 6 clamp the two opposite sides of the fixing plate 3 by spring force, and the two clamp the fixing plate 3 to achieve horizontal direction limiting.

[0034] The utility model is simple to install and convenient to disassemble without the aid of auxiliary tools. After the fixing plate 3 passes through the diamond-shaped hole 4 from bottom to top, it is embedded in the limiting hole 7. By rotating the fixing plate 3, the fixing plate 3 is misaligned with the diamond-shaped hole 4, so that the fixing plate 3 is suspended above the support plate 1. At the same time, the limiting hole 7 covers the fixing plate 3 to play a role in vertical limiting. In addition, under the rotation of the fixing plate 3, the clamping plates 6 are pushed open to the two sides and move away from each other. The clamping plates 6 clamp the fixing plate 3 by spring force to play a role in horizontal limiting. Due to the addition of the vertical and horizontal direction limiting structures, the installation stability is greatly improved, and the fire extinguisher 2 will not loosen and disengage when spraying the fire extinguishing agent.

[0035] In this embodiment, preferably, the fixing plate 3 includes a long side portion 8 and a short side portion 9 that are symmetrically distributed about the center. The long side portion 8 and the short side portion 9 are arranged along the front-back and left-right directions respectively, and the length of the long side portion 8 is greater than the length of the short side portion 9.

[0036] The fixing plate 3 has a rhombus structure. The fixing plate 3 may include a third diagonal line and a fourth diagonal line that are perpendicular to each other. The length of the third diagonal line is greater than that of the fourth diagonal line. The long side portion 8 is located at the end of the third diagonal line and is arranged in the front-rear direction. The short side portion 9 is located at the end of the fourth diagonal line and is arranged in the left-right direction. The long side portion 8 and the short side portion 9 are symmetrically distributed about the center and are located at the four corners of the fixing plate 3. The long side portion 8 is provided with an acute angle, and the short side portion 9 is provided with an obtuse angle. The distance from the long side portion 8 to the center of the fixing plate 3 is greater than the distance from the short side portion 9 to the center of the fixing plate 3, that is, the length of the long side portion 8 is greater than the length of the short side portion 9. Since the diagonal lengths of the fixing plate 3 are inconsistent, the originally vertically aligned fixing plate 3 and the rhombus hole 4 are misaligned under the rotation of the fixing plate 3. In the initial state, the fixing plate 3 is fitted in the limiting hole 7, and the third diagonal line of the fixing plate 3 is aligned with the first diagonal line of the rhombus hole 4. When the fixing plate 3 rotates horizontally by 90 degrees, the third diagonal line of the fixing plate 3 is aligned with the second diagonal line of the rhombus hole 4, and the long side portion 8 extends outward relative to the left and right sides of the rhombus hole 4. The long side portion 8 overlaps above the support plate 1, thereby suspending the fixing plate 3 on the support plate 1, and the support plate 1 plays a role of limiting the fixing plate 3 from below.

[0037] In this embodiment, preferably, the clamping plates 6 are symmetrically arranged on the left and right sides of the rhombus hole 4 and are slidably connected to the support plate 1 in the left-right direction. A return spring 10 is connected between the clamping plates 6 and the mounting plate 5.

[0038] Since the long side portion 8 is located at the end of the third diagonal line and is arranged in the front-rear direction, and the short side portion 9 is located at the end of the fourth diagonal line and is arranged in the left-right direction, the rhombus hole 4 is vertically aligned with the clamping plates 6. When the fixing plate 3 is fitted in the limiting hole 7, with the orientation of the fixing plate 3 as a reference, the first diagonal line is arranged in the front-rear direction, and the second diagonal line is arranged in the left-right direction. The clamping plates 6 are symmetrically arranged with respect to the first diagonal line of the rhombus hole 4 and are distributed on the left and right sides of the rhombus hole 4. The bottom surface of the clamping plate 6 is in contact with the top surface of the support plate 1, and the clamping plate 6 is slidably connected to the support plate 1 in the horizontal direction, and the sliding direction is the left-right direction. The return spring 10 is arranged in the left-right direction, and both ends of the return spring 10 are respectively connected to the clamping plate 6 and the mounting plate 5. In the initial state, the return spring 10 is in a relaxed state and pushes the two clamping plates 6 to approach each other until they close to the first diagonal line of the rhombus hole 4. Since the fixing plate 3 is sleeved with the limiting hole 7, the outer side wall of the long side portion 8 remains in contact with the inner side wall of the limiting hole 7. When the fixing plate 3 rotates in the limiting hole 7, the long side portion 8 can push the clamping plates 6 to the two sides and push the two clamping plates 6 to move away from each other, and the return spring 10 is in a compressed state. The return spring 10 provides a spring force for the clamping plates 6, so that the clamping plates 6 clamp the opposite sides of the fixing plate 3 and perform clamping on the fixing plate 3, and the clamping plates 6 play a role of limiting the fixing plate 3 from the left and right.

[0039] In this embodiment, preferably, the fixing plate 3 is coaxially arranged with the diamond-shaped hole 4 and the limiting hole 7. The top surface of the fixing plate 3 abuts against the bottom surface of the limiting hole 7, and the depth of the limiting hole 7 is equal to the thickness of the fixing plate 3.

[0040] The fixing plate 3 is coaxially arranged with the diamond-shaped hole 4 and the limiting hole 7, and their centers are vertically aligned. Ensure that during the installation process of the fixing plate 3, it can pass upward through the diamond-shaped hole 4 and be embedded in the limiting hole 7. The depth of the limiting hole 7 is equal to the thickness of the fixing plate 3. After the fixing plate 3 is embedded in the limiting hole 7, the bottom surface of the fixing plate 3 is flush with the opening of the limiting hole 7 and flush with the bottom surface of the clamping plate 6. Since the top surface of the supporting plate 1 is in horizontal contact with the bottom surface of the clamping plate 6, and the distance from the bottom surface of the limiting hole 7 to the top surface of the supporting plate 1 is equal to the thickness of the fixing plate 3, after the fixing plate 3 is horizontally rotated, the top surface of the fixing plate 3 abuts against the bottom surface of the clamping plate 6, and the bottom surface of the fixing plate 3 abuts against the top surface of the supporting plate 1. The fixing plate 3 is clamped between the clamping plate 6 and the supporting plate 1, and the clamping plate 6 plays a role in limiting the fixing plate 3 from above.

[0041] In this embodiment, preferably, the outer side wall of the fixing plate 3 abuts against the inner side wall of the limiting hole 7, and the long side portion 8 slides along the inner side wall of the limiting hole 7 under the rotation of the fixing plate 3.

[0042] When the fixing plate 3 is embedded in the limiting hole 7, the limiting hole 7 is sleeved outside the fixing plate 3, the inner side wall of the limiting hole 7 abuts against the outer side wall of the fixing plate 3, and the bottom surface of the limiting hole 7 abuts against the top surface of the fixing plate 3. When the fixing plate 3 rotates horizontally, the long side portion 8 and the short side portion 9 of the fixing plate 3 move along an arc trajectory. The long side portion 8 takes the length of the third diagonal of the fixing plate 3 as the diameter of the arc trajectory, and the short side portion 9 takes the length of the fourth diagonal of the fixing plate 3 as the diameter of the arc trajectory. Since the length of the third diagonal is greater than the length of the fourth diagonal, the length of the long side portion 8 is greater than the length of the short side portion 9. The long side portion 8 serves as the sliding connection position and slides along the inner side wall of the limiting hole 7 under the rotation of the fixing plate 3. Since the relative distance between the two limiting holes 7 is less than the length of the third diagonal, when the long side portion 8 moves along the inner side wall of the limiting hole 7, the distance between the two clamping plates 6 increases, and the clamping plates 6 are pushed open to the two sides and move away from each other until the long side portion 8 is located at the middle position of the inner side wall of the limiting hole 7. The distance between the two clamping plates 6 is the largest, and the return spring 10 is in the maximum compressed state within the moving stroke, and can provide a large spring force for the clamping plates 6 to clamp the fixing plate 3.

[0043] In this embodiment, preferably, a downward limiting post 11 is provided on the bottom surface of the limiting hole 7, a horizontally extending buckle 12 is provided at the end of the limiting post 11, a receiving cavity 13 for accommodating the limiting post 11 is provided on the top surface of the fixing plate 3, and a clamping groove 14 for clamping with the buckle 12 is provided on the inner side wall of the receiving cavity 13.

[0044] The limiting post 11 is arranged downward from the bottom surface of the limiting hole 7 and can be located at the central position of the limiting hole 7, presenting a semi-cylindrical structure. The buckle 12 is located at the end of the limiting post 11 and extends horizontally, and can extend towards the inner side wall of the limiting hole 7, forming a step for clamping with the limiting post 11. The cross-section of the limiting post 11 presents an L-shaped structure. The accommodating cavity 13 is arranged downward from the top surface of the fixing plate 3, and the depth of the accommodating cavity 13 is equal to the length of the limiting post 11. There is a certain moving space in the accommodating cavity 13, and the limiting post 11 can move in the accommodating cavity 13. The clamping groove 14 is opened on the inner side wall of the accommodating cavity 13, and can be arranged around the inner side wall of the accommodating cavity 13, and is matched in shape and corresponding in position with the buckle 12. When the fixing plate 3 is embedded in the limiting hole 7, the limiting post 11 extends into the accommodating cavity 13. As the fixing plate 3 rotates, the clamping plate 6 moves away from the left and right directions, driving the limiting post 11 to move in the left and right directions. The limiting post 11 approaches the inner side wall of the accommodating cavity 13 until the limiting post 11 abuts against the inner side wall of the accommodating cavity 13, and the buckle 12 and the clamping groove 14 are clamped with each other, improving the installation stability.

[0045] In this embodiment, preferably, the accommodating cavity 13 presents a rhombic structure. When the long side portion 8 is located in the middle of the inner side wall of the limiting hole 7, the buckle 12 is clamped with the clamping groove 14 on the side close to the long side portion 8.

[0046] The accommodating cavity 13 presents a rhombic structure and can be approximately set to the outer contour of the fixing plate 3, so that the accommodating cavity 13 can provide sufficient moving space during the movement of the limiting post 11. When the fixing plate 3 is embedded in the limiting hole 7, the limiting post 11 extends into the accommodating cavity 13. As the fixing plate 3 rotates, the long side portion 8 slides along the inner side wall of the limiting hole 7, the clamping plates 6 are pushed open and move away from each other, driving the limiting post 11 to move in the left and right directions. The limiting post 11 approaches the inner side wall of the accommodating cavity 13. Until the fixing plate 3 rotates by 90 degrees, the long side portion 8 is located in the middle position of the inner side wall of the limiting hole 7, the clamping plate 6 moves to the maximum stroke, the clamping groove 14 on the side close to the long side portion 8 is aligned with the middle of the inner side wall of the limiting hole 7, the limiting post 11 abuts against the inner side wall of the accommodating cavity 13, and the buckle 12 and the clamping groove 14 are clamped with each other, improving the installation stability.

[0047] In this embodiment, preferably, a stroke block 15 protruding outward is provided on the inner side wall of the limiting hole 7, and a stroke groove 16 matching the stroke block 15 is provided on the outer side wall of the long side portion 8. The stroke block 15 and the stroke groove 16 are clamped with each other.

[0048] The travel block 15 is located on the inner side wall of the limit hole 7 and protrudes outward, extending in the left-right direction. It can be that the travel block 15 is located at the middle position of the inner side wall of the limit hole 7, and the outer side of the travel block 15 has an arc structure, which can limit the fixing plate 3. The travel groove 16 is located on the outer side wall of the long side portion 8 and is recessed inward, matching the shape of the travel block 15. When the fixing plate 3 is installed in the limit hole 7, as the fixing plate 3 rotates, the long side portion 8 moves along the inner side wall of the limit hole 7 until the fixing plate 3 rotates 90 degrees, and the long side portion 8 is located at the middle position of the inner side wall of the limit hole 7. The clamping plate 6 moves to the maximum stroke, and the travel block 15 is clamped with the travel groove 16, so that when the staff installs the fire extinguisher 2, they can tactilely sense that the fixing plate 3 has been installed in place, improving the positioning accuracy.

[0049] In this embodiment, preferably, a coaxial frustum 17 is provided below the fixing plate 3. The outer side wall of the frustum 17 is tangent to the inner side wall of the diamond-shaped hole 4, and the frustum 17 is rotatably connected to the diamond-shaped hole 4.

[0050] The frustum 17 is located below the fixing plate 3. The top surface of the frustum 17 is in contact with the bottom surface of the fixing plate 3 and is coaxial with the fixing plate 3. The height of the frustum 17 is equal to the depth of the diamond-shaped hole 4 and equal to the thickness of the support plate 1. When the fixing plate 3 is installed in the limit hole 7, the diamond-shaped hole 4 is coaxial with the frustum 17, and the outer side wall of the frustum 17 is tangent to the inner side wall of the diamond-shaped hole 4. Since the distances from the four sides of the diamond to the midpoint are equal, the four side walls of the diamond-shaped hole 4 remain in contact with the outer side wall of the frustum 17, and the diamond-shaped hole 4 is sleeved on the outer side of the frustum 17. As the fixing plate 3 rotates, the frustum 17 is rotatably connected to the diamond-shaped hole 4, making the installation structure more compact, ensuring the coaxial relationship between components, and improving the rotation stability.

[0051] In this embodiment, preferably, a top plate is provided above the mounting plate 5. An observation port is provided in the middle of the top plate along the front-back direction of the diamond-shaped hole 4. Marking lines for identification are provided on the diamond-shaped hole 4 and the short side portion 9 respectively.

[0052] The top plate is stacked above the mounting plate 5 and is detachably connected to the mounting plate 5. A hollow observation port is provided in the middle of the top plate. The observation port has a through groove structure and is arranged along the front-back direction of the diamond-shaped hole 4, and can correspond to the position of the first diagonal line of the diamond-shaped hole 4. Marking lines are respectively arranged on the diamond-shaped hole 4 and the short side portion 9, and can be arranged on the outer side of the diamond-shaped hole 4 and the top surface of the short side portion 9, which has the function of identifying the direction. When the fixing plate 3 is embedded in the limiting hole 7, the long side portion 8 is aligned with the first diagonal line of the diamond-shaped hole 4, and the short side portion 9 is aligned with the second diagonal line of the diamond-shaped hole 4. As the fixing plate 3 rotates, the long side portion 8 and the short side portion 9 move along an arc trajectory until the fixing plate 3 rotates by 90 degrees. The long side portion 8 is located at the middle position of the inner side wall of the limiting hole 7, the long side portion 8 is aligned with the second diagonal line of the diamond-shaped hole 4, and the short side portion 9 is aligned with the first diagonal line of the diamond-shaped hole 4. The staff can check the situation through the observation port and confirm that the marking lines of the diamond-shaped hole 4 and the short side portion 9 are aligned with each other, so that when the staff installs the fire extinguisher 2, they can visually perceive that the fixing plate 3 has been installed in place, improving the positioning accuracy.

[0053] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
