Description

Technical Field

[0001] This invention belongs to the field of fire hydrant housing technology, and particularly relates to fire hydrant housings based on precision machining processes. Background Technology

[0002] Fire hydrants, formally known as fire shut-off hydrants, are fixed fire-fighting facilities whose main function is to control combustibles, isolate oxidizers, and eliminate ignition sources. They are divided into indoor and outdoor fire hydrants. The outer shell of indoor fire hydrants is mainly manufactured using precision machining processes. However, conventional indoor fire hydrants are usually installed indoors and occupy a certain amount of indoor space, making them susceptible to damage from collisions with the external environment. Furthermore, since the door frame structure of indoor fire hydrant outer shells is usually made of glass, its susceptibility to impact damage is limited by the characteristics of glass. This not only affects the protective performance of the fire hydrant outer shell, but the breakage of the glass can also easily cause safety accidents, affecting usability.

[0003] Combining the two issues mentioned above, it becomes clear that existing fire hydrant casings on the market cannot simultaneously avoid the problems raised, thus failing to achieve our desired effect. Therefore, we propose a fire hydrant casing based on precision machining technology that can reduce the indoor space occupied by the fire hydrant casing, reduce the possibility of glass breakage, and improve usability. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing fire hydrant shells based on precision machining processes. Its advantages include the use of a mounting frame in conjunction with the shell body, allowing the fire hydrant shell structure to be installed into a pre-designed mounting slot in the interior wall using fasteners. This reduces the area occupied by the fire hydrant shell, minimizing disruption to daily life and work, and reducing the likelihood of damage from impacts. Furthermore, the use of positioning and connecting components facilitates connection between the shell body and the mounting frame, enabling easy assembly and disassembly. By incorporating a heat insulation layer and an impact-resistant layer on the insulating glass of the shell body, the heat insulation layer enhances the high-temperature resistance of the fire hydrant shell glass, preventing it from burning during a fire and improving the protection of the equipment inside. The impact-resistant layer increases the strength and impact resistance of the fire hydrant shell glass, making it less prone to breakage and shattering under impact, ensuring usability and reducing the risk of accidents.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a fire hydrant shell based on a precision machining process, comprising a mounting frame and a shell body, wherein the shell body is disposed inside the mounting frame, and both the mounting frame and the shell body are embedded in the wall.

[0006] The mounting frame includes two fixed frames, and a connecting frame is bolted between the opposite sides of the two fixed frames. The connecting frame is rectangular and bolted to the four corners between the opposite sides of the two fixed frames. Fasteners are provided inside the connecting frame. The outer shell body is located inside the fixed frame. Positioning parts are embedded in the top and bottom of the inner wall of the fixed frame. Connecting parts are provided on both sides of the inner wall of the outer shell body. The side of the connecting part closest to the positioning part extends into its interior.

[0007] The outer shell body includes a shell, and the shell is located inside the fixed frame. A door frame is rotatably connected to the front side of the shell, and an insulating glass is embedded inside the door frame.

[0008] The insulating glass includes a protective glass body, and a heat insulation layer is provided on the front side of the protective glass body, and an impact-resistant layer is provided on the front side of the heat insulation layer.

[0009] By adopting the above technical solution, and through the cooperation of the mounting frame and the outer shell, the fire hydrant outer shell structure can be installed in the pre-set mounting groove in the indoor wall using the fasteners of the mounting frame. This reduces the area occupied by the fire hydrant outer shell in the room, making it less likely to affect people's daily work and life, and thus reducing the possibility of damage to the fire hydrant outer shell structure due to collisions. At the same time, the cooperation of positioning parts and connecting parts makes it easy to connect the outer shell and the mounting frame, achieving the effect of easy assembly and disassembly. By setting a heat insulation layer and an impact-resistant layer on the insulating glass of the outer shell, the heat insulation layer can improve the high temperature resistance of the fire hydrant outer shell glass, making it less likely to be burned during a fire, thereby improving the protection of the equipment inside the box. The impact-resistant layer can improve the strength and impact resistance of the fire hydrant outer shell glass, so it is not easy to break or shatter when subjected to external impacts, which not only ensures usability but also reduces the occurrence of safety accidents.

[0010] The present invention is further configured such that: the fastener includes a bidirectional screw, and the bidirectional screw is rotatably connected inside the connecting frame; the front side of the bidirectional screw extends into the interior of the front fixing frame; the front and rear sides of the surface of the bidirectional screw are threaded with screw blocks, and the surface of the screw blocks is fitted with fixing blocks; the interior of the fixing blocks is rotatably connected with connecting rods; the other ends of the two connecting rods are rotatably connected with a support block, and one side of the support block is in close contact with the inner wall of the wall.

[0011] By adopting the above technical solution and setting fasteners, when the fixing frame is placed in the preset mounting hole in the wall, the double-ended screw can be rotated by a tool. With the threaded engagement between the double-ended screw and the screw block, the two screw blocks can drive the fixing block to move relative to each other. Under the action of the connecting rod, the support block can be moved gradually towards the inner wall of the wall until the support block is in close contact with the inner wall of the wall. This achieves the effect of firmly installing the mounting frame in the preset mounting hole in the wall. Moreover, the installation method without expansion bolts has the effect of not damaging the wall.

[0012] The invention is further configured such that: the side of the connecting rod away from the fixed block extends to the outside of the connecting frame, and the side of the support block away from the connecting frame is bolted with an anti-slip pad, and the side of the anti-slip pad away from the support block is concave and convex.

[0013] By adopting the above technical solution, and by setting an anti-slip pad with a concave-convex design on the side of the anti-slip pad away from the support block, the friction between the support block and the inner wall of the wall can be increased, further improving the installation stability of the installation frame.

[0014] The present invention is further configured such that: the positioning component includes a fixed shell, the fixed shell is respectively bolted to the top and bottom of the inner wall of the fixed frame, a movable block is slidably connected inside the fixed shell, and the movable block is used in conjunction with the connecting component, a damping telescopic rod is bolted to the rear side of the movable block, and the rear side of the damping telescopic rod is bolted to the inner wall of the fixed shell, a return spring is sleeved on the surface of the damping telescopic rod, and the side of the return spring near the movable block and the inner wall of the fixed shell is respectively bolted to both.

[0015] By adopting the above technical solution, by setting a positioning component, the connecting component can contact the moving block, and under the inward push of the outer shell body, the moving block moves inside the fixed shell, gradually squeezing the damping telescopic rod and the return spring to retract, until one end of the connecting component contacts the inner wall of the fixed shell, thus achieving the effect of connecting the outer shell body to the mounting frame. When the connecting component moves out of the fixed shell, the elasticity of the damping telescopic rod and the return spring can push the moving block to reset, thereby driving the outer shell body to move out of the mounting frame, achieving the effect of separating the outer shell body from the mounting frame, which facilitates the disassembly and assembly of the outer shell body.

[0016] The present invention is further configured such that: the connecting member includes a rotating rod, the rotating rod is rotatably connected to both sides inside the housing, and a connecting rope is wound around the surface of the rotating rod; the other end of the connecting rope is connected to a positioning rod; the positioning rod extends into the interior of the moving block from the side near the moving block; support blocks are bolted to both sides inside the housing; a positioning spring is bolted between the support block and the opposite side of the positioning rod; and one end of the connecting rope passes through the positioning spring and is connected to the positioning rod.

[0017] By adopting the above technical solution, by setting up a connecting part, the connecting rope can be gradually wound up by rotating the rotating rod, which can drive the positioning rod to move into the body of the outer shell and squeeze the positioning spring, thereby achieving the effect of separating the connecting part from the positioning part. Through the elasticity of the positioning spring, the positioning rod can be moved out of the body of the outer shell, realizing the connection between the positioning rod and the moving block, thus achieving the effect of connecting the connecting part and the positioning part.

[0018] The present invention is further configured such that: the positioning rod extends into the interior of the moving block on the side near the moving block, and both the moving block and the fixed shell have positioning holes that cooperate with the positioning rod.

[0019] By adopting the above technical solution, when the outer shell body is placed in the mounting frame by setting positioning holes, the positioning rod first enters the positioning hole in the moving block and makes one side of the positioning rod contact the inner wall of the fixed shell, thereby connecting the positioning rod and the moving block. Then, under the gradual pushing of the outer shell body, the positioning rod and the moving block slide inside the fixed shell. When the positioning rod moves to the positioning hole in the fixed shell, under the elastic action of the positioning spring, it can enter the interior of the fixed shell, thereby achieving the effect of locking the position of the outer shell body and preventing it from moving randomly.

[0020] The present invention is further configured such that: the heat insulation layer is made of PET film and is adhered to the front side of the protective glass body; and the impact-resistant layer is made of polyester composite film and is adhered to the front side of the heat insulation layer.

[0021] By adopting the above technical solution, the heat insulation layer is made of PET film, which can improve the high temperature resistance of the fire hydrant shell glass, making it less likely to be burned during a fire, thereby improving the protection of the equipment inside the box. By making the impact-resistant layer of polyester film, the strength and impact resistance of the fire hydrant shell glass can be improved. Therefore, it is not easy to break or shatter when subjected to external impact, which not only ensures usability, but also reduces the occurrence of safety accidents.

[0022] The present invention is further configured such that: the protective glass body includes an outer glass and an inner glass, and fire-retardant adhesive is injected between the opposite sides of the outer glass and the inner glass, and is respectively bonded to the outer glass and the side glass.

[0023] By adopting the above technical solution, the protective glass body is composed of an outer glass, an inner glass, and fire-retardant adhesive. The double-layer glass design enhances the protective properties of the outer shell, while the interlayer of fire-retardant adhesive greatly improves the fire resistance of the outer shell glass, ensuring the protection of the equipment inside the fire hydrant shell.

[0024] The present invention is further configured such that: the thickness of the outer glass is 8mm, the thickness of the inner glass is 5mm, and both the outer glass and the inner glass are made of borosilicate glass.

[0025] By adopting the above technical solution, and by setting the outer glass to be 8mm thick borosilicate glass and the inner glass to be 5mm thick borosilicate glass respectively, the strength of the fire hydrant shell glass can be increased by increasing the thickness of the insulating glass, making it less prone to damage.

[0026] The present invention is further configured such that: slots are provided on both sides of the interior of the housing, and the positioning element is located inside the slots.

[0027] By adopting the above technical solution and setting a pre-set hole and groove structure inside the housing, it is possible to facilitate the connection between the main body of the outer shell and the mounting frame through the connector.

[0028] In summary, the present invention has the following beneficial effects:

[0029] 1. By setting up the installation frame and the outer shell body in cooperation, the fire hydrant outer shell structure can be installed in the pre-set installation groove in the indoor wall through the fasteners of the installation frame. This reduces the area occupied by the fire hydrant outer shell in the room, making it less likely to affect people's daily work and life, and thus reducing the possibility of the fire hydrant outer shell structure being damaged by collision. At the same time, by using the positioning parts and connecting parts in cooperation, it is possible to connect the outer shell body and the installation frame, so as to achieve the effect of easy disassembly and assembly.

[0030] 2. By incorporating a heat insulation layer and an impact-resistant layer on the insulating glass of the main body of the fire hydrant, the heat insulation layer enhances the high-temperature resistance of the fire hydrant's outer glass, making it less susceptible to burn-out during a fire and thus improving the protection of the equipment inside. The impact-resistant layer enhances the strength and impact resistance of the fire hydrant's outer glass, making it less prone to breakage and shattering when subjected to external impacts. This not only ensures usability but also reduces the occurrence of safety accidents. Attached Figure Description

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Example 1:

[0041] refer to Figure 1-5 The fire hydrant shell based on precision machining technology includes a mounting frame 1 and a shell body 2. The shell body 2 is set inside the mounting frame 1, and both the mounting frame 1 and the shell body 2 are embedded in the wall.

[0042] The mounting frame 1 includes two fixed brackets 11, and a connecting bracket 12 is bolted between the opposite sides of the two fixed brackets 11. The connecting bracket 12 is rectangular and bolted to the four corners between the opposite sides of the two fixed brackets 11. Fasteners 13 are provided inside the connecting bracket 12. The outer shell body 2 is located inside the fixed bracket 11. Positioning members 14 are embedded in the top and bottom of the inner wall of the fixed bracket 11, and connecting members 15 are provided on both sides of the inner wall of the outer shell body 2. The side of the connecting member 15 closest to the positioning member 14 extends into its interior. By setting the mounting frame 1 and the outer shell body 2 together, the fire hydrant outer shell structure can be installed in the pre-set installation groove in the indoor wall through the fasteners 13 of the mounting frame 1. This reduces the area occupied by the fire hydrant outer shell in the room, making it less likely to affect people's daily work and life, and thus reducing the possibility of the fire hydrant outer shell structure being damaged by collision. At the same time, by using the positioning member 14 and the connecting member 15 together, it is easy to connect the outer shell body 2 and the mounting frame 1, achieving the effect of easy assembly and disassembly.

[0043] like Figure 3 As shown, the fastener 13 includes a bidirectional screw 131, which is rotatably connected to the interior of the connecting frame 12. The front side of the bidirectional screw 131 extends into the interior of the front fixing frame 11. Screw blocks 132 are threaded onto both the front and rear sides of the surface of the bidirectional screw 131, and fixing blocks 133 are fitted onto the surface of the screw blocks 132. Connecting rods 134 are rotatably connected inside the fixing blocks 133. A support block 135 is rotatably connected between the other ends of the two connecting rods 134, and one side of the support block 135 is in close contact with the inner wall of the wall. By setting the fastener 13, it is possible to... When the mounting bracket 11 is placed in the pre-set mounting hole in the wall, the double-ended screw 131 can be rotated with a tool. With the threaded engagement between the double-ended screw 131 and the screw block 132, the two screw blocks 132 can drive the fixing block 133 to move relative to each other. Under the action of the connecting rod 134, the support block 135 can be moved gradually towards the inner wall of the wall until the support block 135 is in close contact with the inner wall of the wall. This achieves the effect of firmly installing the mounting frame 1 in the pre-set mounting hole in the wall. Moreover, the installation method without expansion bolts has the effect of not damaging the wall.

[0044] like Figure 3 As shown, the connecting rod 134 extends to the outside of the connecting frame 12 on the side away from the fixing block 133. The anti-slip pad 3 is bolted to the side of the support block 135 away from the connecting frame 12. The anti-slip pad 3 is concave and convex on the side away from the support block 135. By setting the anti-slip pad 3 and the concave and convex design on the side away from the support block 135, the friction between the support block 135 and the inner wall of the wall can be increased, further improving the installation firmness of the mounting frame 1.

[0045] like Figure 4As shown, the positioning component 14 includes a fixed housing 141, which is bolted to the top and bottom of the inner wall of the fixed frame 11. A movable block 142 is slidably connected inside the fixed housing 141, and the movable block 142 cooperates with the connecting component 15. A damping telescopic rod 143 is bolted to the rear side of the movable block 142, and the rear side of the damping telescopic rod 143 is bolted to the inner wall of the fixed housing 141. A return spring 144 is sleeved on the surface of the damping telescopic rod 143, and the side of the return spring 144 closest to the movable block 142 and the inner wall of the fixed housing 141 is bolted to both. By setting the positioning component 14, the movable block 142 can be connected to the connecting component 15. The contact and the inward push of the outer shell 2 cause the moving block 142 to move inside the fixed shell 141, gradually squeezing the damping telescopic rod 143 and the return spring 144 to retract until one end of the connecting piece 15 contacts the inner wall of the fixed shell 141, thus achieving the effect of connecting the outer shell 2 to the mounting frame 1. When the connecting piece 15 moves out of the fixed shell 141, the elasticity of the damping telescopic rod 143 and the return spring 144 can push the moving block 142 to return to its original position, thereby moving the outer shell 2 out of the mounting frame 1, achieving the effect of separating the outer shell 2 from the mounting frame 1, which facilitates the disassembly and assembly of the outer shell 2.

[0046] like Figure 5 As shown, the connector 15 includes a rotating rod 151, which is rotatably connected to both sides inside the housing 21. A connecting rope 152 is wound around the surface of the rotating rod 151, and the other end of the connecting rope 152 is connected to a positioning rod 153. The positioning rod 153 extends into the interior of the moving block 142 from the side near the moving block 142. Support blocks 154 are bolted to both sides inside the housing 21. A positioning spring 155 is bolted between the support block 154 and the opposite side of the positioning rod 153. One end of the connecting rope 152 passes through the positioning spring 153. The positioning spring 155 is connected to the positioning rod 153. By setting the connecting piece 15, the connecting rope 152 can be gradually wound up by rotating the rotating rod 151. This can drive the positioning rod 153 to move into the outer shell body 2 and squeeze the positioning spring 155, thereby achieving the effect of separating the connecting piece 15 from the positioning piece 14. Through the elasticity of the positioning spring 155, the positioning rod 153 can be moved out of the outer shell body 2, realizing the connection between the positioning rod 153 and the moving block 142, thus achieving the effect of connecting the connecting piece 15 and the positioning piece 14.

[0047] like Figure 4As shown, the positioning rod 153 extends into the interior of the moving block 142 from the side near the moving block 142. Both the moving block 142 and the fixed shell 141 have positioning holes 4 that cooperate with the positioning rod 153. By setting the positioning holes 4, when the outer shell body 2 is placed in the mounting frame 1, the positioning rod 153 first enters the positioning hole 4 in the moving block 142 and makes one side of the positioning rod 153 contact the inner wall of the fixed shell 141, thus connecting the positioning rod 153 and the moving block 142. Then, under the gradual pushing of the outer shell body 2, the positioning rod 153 and the moving block 142 slide inside the fixed shell 141. When the positioning rod 153 moves to the positioning hole 4 in the fixed shell 141, under the elastic action of the positioning spring 155, it can enter the interior of the fixed shell 141, thereby achieving the effect of locking the position of the outer shell body 2 and preventing it from moving freely.

[0048] like Figure 5 As shown, slots are provided on both sides inside the housing 21, and the positioning member 14 is located inside the slot. By setting the pre-set slot structure inside the housing 21, it is possible to facilitate the connection between the outer shell body 2 and the mounting frame 1 through the connector 15.

[0049] Brief description of the usage process: Place the fixing bracket 11 into the pre-set mounting hole in the wall. Rotate the double-ended screw 131 with a tool. With the threaded engagement of the double-ended screw 131 and the screw block 132, the two screw blocks 132 can drive the fixing block 133 to move relative to each other. Under the action of the connecting rod 134, the support block 135 can be moved gradually towards the inner wall of the wall until the support block 135 is in close contact with the inner wall of the wall. The anti-slip pad 3 helps to make the support block 135 fit tightly against the inner wall of the wall, completing the connection between the mounting frame 1 and the wall. Then, by rotating the rotating rod 151, the connecting rope 152 is gradually wound up, which can drive the positioning rod 153 to move into the inner shell body 2 and squeeze the positioning spring 155. Then, the outer shell body 2 is placed inside the mounting frame 1, and the positioning rod 153 and the moving block 142 are on the same axis. Then, through the elasticity of the positioning spring 155, the positioning rod 153 can be moved out of the inner shell body 2 and into the moving block 142. The interior of the moving block 142 slides in contact with the inner wall of the fixed shell 141. Then, under the gradual pushing of the outer shell body 2, the positioning rod 153 and the moving block 142 slide inside the fixed shell 141. At the same time, the damping telescopic rod 143 and the return spring 144 retract. When the positioning rod 153 moves to the positioning hole 4 inside the fixed shell 141, under the elastic action of the positioning spring 155, the positioning rod 153 can enter the positioning hole 4 inside the fixed shell 141, locking the position of the outer shell body 2 and completing the installation of the outer shell body 2. When it is necessary to remove the outer shell body 2, simply move the positioning rod 153 out of the interior of the fixed shell 141. Using the elasticity of the damping telescopic rod 143 and the return spring 144, the moving block 142 can be pushed back to its original position, thereby moving the outer shell body 2 out of the interior of the mounting frame 1. Then, the positioning rod 153 and the moving block 142 can be separated, thus completing the removal of the outer shell body 2.

[0050] Example 2:

[0051] refer to Figure 2 , 6 7, including mounting frame 1 and outer shell body 2, the outer shell body 2 is disposed inside the mounting frame 1, and both the mounting frame 1 and the outer shell body 2 are embedded in the wall;

[0052] The outer shell body 2 includes a shell 21, and the shell 21 is located inside the fixing frame 11. A door frame 22 is rotatably connected to the front side of the shell 21, and an insulating glass 23 is embedded inside the door frame 22.

[0053] The insulating glass 23 includes a protective glass body 231, and a heat insulation layer 232 is provided on the front side of the protective glass body 231. An impact-resistant layer 233 is provided on the front side of the heat insulation layer 232. By combining the heat insulation layer 232 and the impact-resistant layer 233 on the insulating glass 23 of the outer shell body 2, the heat insulation layer 232 can improve the high temperature resistance of the fire hydrant outer shell glass, making it less likely to be burned during a fire, thereby improving the protection of the equipment inside the box. The impact-resistant layer 233 can improve the strength and impact resistance of the fire hydrant outer shell glass, so it is not easy to break or shatter when subjected to external impact, which not only ensures usability but also reduces the occurrence of safety accidents.

[0054] like Figure 6 As shown, the heat insulation layer 232 is made of PET film and is bonded to the front side of the protective glass body 231. The impact-resistant layer 233 is made of polyester composite film and is bonded to the front side of the heat insulation layer 232. By setting the heat insulation layer 232 to be made of PET film, the high temperature resistance of the fire hydrant shell glass can be improved, making it less likely to be burned during a fire, thereby improving the protection of the equipment inside the box. By setting the impact-resistant layer 233 to be made of polyester composite film, the strength and impact resistance of the fire hydrant shell glass can be improved. Therefore, it is not easy to break or shatter when subjected to external impact, which not only ensures usability but also reduces the occurrence of safety accidents.

[0055] like Figure 7 As shown, the protective glass body 231 includes an outer glass 2311 and an inner glass 2312. Fire retardant 2313 is injected between the opposite sides of the outer glass 2311 and the inner glass 2312, and is bonded to the outer glass 2311 and the side glass respectively. By setting the protective glass body 231 to be composed of the outer glass 2311, the inner glass 2312 and the fire retardant 2313, the double-layer glass setting can improve the protection of the outer shell body 2. At the same time, by utilizing the interlayer setting of the fire retardant 2313, the fire resistance of the glass of the outer shell body 2 can be greatly improved, ensuring the protection of the equipment inside the fire hydrant shell.

[0056] like Figure 7 As shown, the outer glass 2311 has a thickness of 8mm, and the inner glass 2312 has a thickness of 5mm. Both the outer glass 2311 and the inner glass 2312 are made of borosilicate glass. By setting the outer glass 2311 to be 8mm thick and the inner glass 2312 to be 5mm thick, the strength of the fire hydrant shell glass can be increased by increasing the thickness of the insulating glass 23, making it less prone to damage.

[0057] Brief description of usage: By sealing the door frame 22 with insulating glass 23 and using fire-retardant adhesive 2313 as a layer, the fire resistance of the outer shell 2 glass is greatly improved, ensuring the protection of the equipment inside the fire hydrant shell. By using a heat insulation layer 232 made of PET film, the high temperature resistance of the fire hydrant shell glass is improved, making it less likely to be burned in a fire, thereby improving the protection of the equipment inside the box. By using an impact-resistant layer 233 made of polyester composite film, the strength and impact resistance of the fire hydrant shell glass are improved. Therefore, it is not easy to break or shatter when subjected to external impact, which not only ensures usability but also reduces the occurrence of safety accidents.
