Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, specifically a new type of door breacher for fire fighting. Background Technology

[0002] Door breakers, as a type of mechanical tool, are now widely used in firefighting operations.

[0003] The utility model patent application with publication number "CN203886036U" discloses a new type of fire door breacher, which mainly consists of a hydraulic manual pump, a reversing switch, a control hand, a fixed bracket, a hand handle, a breaching clamp body, a cutting clamp mouth, and a semi-circular auxiliary expansion column. The technical solution has a simple structure and makes adjustments and improvements to the original hydraulic spreader for new door breaching methods, making fire door breaching faster.

[0004] The new type of fire door breacher disclosed in the above document has the following defects: the breaching clamps cannot be rotated, and the breaching clamps have certain limitations in use, making it impossible to use at specific angles, resulting in poor practicality.

[0005] Therefore, it can be seen that the existing door breaching tool for fire protection cannot rotate, and it is necessary to improve the existing shortcomings and provide a new type of door breaching tool for fire protection. Summary of the Invention

[0006] The purpose of this utility model is to provide a new type of door breacher for fire protection, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a novel fire-fighting door breacher, comprising a housing, an internal hydraulic pump, a fixed bracket at one end of the housing, an output end of the hydraulic pump passing through the housing and the fixed bracket, a rotating head rotatably connected to the output end of the hydraulic pump, breaching clamps hinged to both ends of the fixed bracket, a connecting plate hinged to one end of each of the two breaching clamps, a connecting block hinged to the other end of the connecting plate, a connecting block mounted on the rotating head via a fixing assembly, and an angle adjustment assembly inside the housing.

[0009] Furthermore, the angle adjustment component includes a first gear, the outer surface of the fixed bracket is provided with the first gear, the end of the first gear away from the fixed bracket is provided with a sleeve, the outer surface of the outer shell is provided with a groove, the sleeve is rotatably connected inside the groove, the output end of the hydraulic pump is slidably connected inside the sleeve, one end of the outer shell is provided with a through hole, the inside of the through hole is rotatably connected with a connecting rod, one end of the connecting rod is provided with a second gear, the other end of the connecting rod is installed with a rotating handle, and the second gear is meshed with the first gear.

[0010] Furthermore, the fixing component includes a mounting block, one end of which is provided with a slider. The slider has a cavity inside, and a fixing block is slidably connected inside the cavity. There are two fixing blocks, which are symmetrically distributed. A spring is installed between the two fixing blocks. Both the rotating head and the connecting block have mounting holes. A slider is installed inside the mounting holes. The outer surface of the fixing block abuts against the outer surface of the connecting block.

[0011] Furthermore, a groove is provided on the inner surface of the cavity, and a limiting block is provided on the outer surface of the fixing block, with the limiting block slidably connected inside the groove.

[0012] Furthermore, the outer surface of the fixing block is provided with an inclined surface.

[0013] Furthermore, the upper surface of the housing is provided with a handle, and the lower surface of the housing is provided with a pad.

[0014] This utility model has the following beneficial effects:

[0015] (1) By rotating the rotating handle, the rotating handle drives the connecting rod to rotate, which in turn drives the second gear to rotate, and the second gear drives the first gear to rotate, so that the sleeve rotates axially along the shaft in the groove. During the rotation of the second gear, the fixed bracket rotates synchronously, thereby adjusting the angle of the demolition clamp and increasing the effectiveness of the demolition clamp.

[0016] (2) This utility model causes the two fixed blocks to move into the cavity by squeezing the fixed blocks at both ends of the slider inward. At the same time, the spring gradually contracts. When the outer surface of the fixed block is flush with the outer surface of the slider, the mounting block can be pulled outward to make the slider detach from the mounting hole, thereby completing the separation of the connecting block and the rotating head, which facilitates disassembly.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1 - Figure 4As shown, this utility model is a new type of fire door breacher, including a shell 1, a hydraulic pump 2 installed inside the shell 1, a fixed bracket 3 provided at one end of the shell 1, the output end of the hydraulic pump 2 passing through the shell 1 and the fixed bracket 3 in sequence, a rotating head 9 rotatably connected to the output end of the hydraulic pump 2, two breaching clamps 4 hinged to both ends of the fixed bracket 3, a connecting plate 5 hinged to one end of each of the two breaching clamps 4, a connecting block 6 hinged to the other end of the connecting plate 5, the rotating head 9 is mounted with the connecting block 6 through a fixing component 7, and an angle adjustment component 8 is provided inside the shell 1;

[0027] The upper surface of the outer casing 1 is provided with a handle 101, and the lower surface of the outer casing 1 is provided with a pad 102;

[0028] When it is necessary to break down a security door, hold the handle 101 and place the door breaker in the place to be used. Drill a hole along the door gap with an electric drill, then insert the breaking pliers 4 into the drilled hole. Then operate the hydraulic pump 2 so that the output end of the hydraulic pump 2 pushes the connecting block 6 to move outward in the fixed bracket 3. During the movement of the connecting block 6, the two breaking pliers 4 are opened through the connecting plate 5, thereby opening the door gap and completing the breaking down.

[0029] The angle adjustment component 8 includes a first gear 801. The first gear 801 is provided on the outer surface of the fixed bracket 3. A sleeve 802 is provided at the end of the first gear 801 away from the fixed bracket 3. A groove is provided on the outer surface of the outer shell 1. The sleeve 802 is rotatably connected inside the groove. The output end of the hydraulic pump 2 is slidably connected inside the sleeve 802. A through hole is provided at one end of the outer shell 1. A connecting rod 803 is rotatably connected inside the through hole. A second gear 804 is provided at one end of the connecting rod 803. A rotating handle 805 is installed at the other end of the connecting rod 803. The second gear 804 meshes with the first gear 801.

[0030] When it is necessary to rotate the angle of the demolition clamp body 4, the rotating handle 805 is turned, which drives the connecting rod 803 to rotate, which in turn drives the second gear 804 to rotate, and the second gear 804 drives the first gear 801 to rotate, so that the sleeve 802 rotates axially along the shaft in the groove. During the rotation of the second gear 804, the fixed bracket 3 rotates synchronously, thereby adjusting the angle of the demolition clamp body 4 and increasing the effectiveness of the demolition clamp body 4.

[0031] The fixing component 7 includes a mounting block 701, a slider 702 at one end of the mounting block 701, a cavity 703 inside the slider 702, a fixing block 704 slidably connected inside the cavity 703, two fixing blocks 704 are provided and symmetrically distributed, a spring 705 is installed between the two fixing blocks 704, the rotating head 9 and the connecting block 6 are both provided with mounting holes, the slider 702 is installed inside the mounting holes, and the outer surface of the fixing block 704 abuts against the outer surface of the connecting block 6;

[0032] The inner surface of the cavity 703 is provided with a sliding groove 706, and the outer surface of the fixing block 704 is provided with a limiting block 707, which is slidably connected to the inside of the sliding groove 706.

[0033] By using the sliding groove 706 and the limiting block 707 together, the position of the fixing block 704 in the cavity 703 can be limited, so that the fixing block 704 will not come out of the cavity 703, thus achieving a good limiting effect.

[0034] The outer surface of the fixing block 704 is provided with a bevel;

[0035] By pressing the fixing blocks 704 at both ends of the slider 702 inward, the two fixing blocks 704 move into the cavity 703. At the same time, the spring 705 gradually contracts. When the outer surface of the fixing block 704 is flush with the outer surface of the slider 702, the mounting block 701 can be pulled outward, so that the slider 702 is disengaged from the mounting hole, thereby completing the separation of the connecting block 6 and the rotating head 9, which facilitates disassembly.
