Description

Technical Field

[0001] This application relates to the field of fire-fighting tools technology, and in particular to an auxiliary tool for breaking down burglar bars. Background Technology

[0002] In the event of a fire, firefighters need to use various tools to rescue people trapped inside. Many existing entrance windows use burglar bars, which sometimes need to be removed during firefighting to gain entry for rescue or firefighting. This is typically done by using a cutting device to directly cut the burglar bars. Because the bars are made of round metal with a smooth surface, the cutting device is prone to slipping during the cutting process. Ensuring the stability of the cutting device and the parts being cut during this process is a critical technical problem that needs to be solved. Utility Model Content

[0003] In order to overcome the shortcomings of existing cutting devices that are prone to slipping and shaking during the cutting process, this application provides an auxiliary tool for breaking burglar bars, which fixes the cutting device to the position of the machine to be cut, thereby improving cutting efficiency and enhancing operational safety.

[0004] To achieve the above objectives, this application adopts the following technical solution: An auxiliary tool for breaking down burglar bars is characterized by comprising a housing; a cutting machine slidably connected to the housing; a hook portion disposed at the front end of the housing and opposite to the cutting machine; an opening and a receiving groove connected to the opening are formed between the housing and the hook portion; when in the cutting state, the cutting part of the cutting machine enters the receiving groove; when in the non-cutting state, the cutting part of the cutting machine exits the receiving groove.

[0005] The above technical solution involves an external housing for the cutting machine, with a hook at the front end of the housing. The hook is then fitted onto the railing of the security window, allowing the railing to enter the receiving groove through the opening, preventing it from easily coming off. Once the railing is secured, the cutting machine is pushed forward to cut the railing when cutting is required. The housing and hook fix the position of the cutting device and the railing, preventing slippage during the cutting process, improving cutting efficiency, and ensuring safety during the cutting process.

[0006] Optionally, it also includes a pushing component, which includes a fixing part and a pushing part. The fixing part is slidably connected to the housing, and the cutting machine is fixed to the fixing part. The pushing part is fixedly connected to the fixing part, and the pushing part pushes the fixing part to slide along the housing.

[0007] By adopting the above technical solution, the pushing part pushes the fixing part, and the fixing part slides relative to the housing, thereby driving the cutting machine to move forward or backward to perform the cutting operation. The pushing component can effectively reduce the vibration transmitted to the hand, extend the operator's operation time, and improve the safety during the cutting process.

[0008] Optionally, the pushing assembly also includes a guide portion, one end of which is fixed to the housing and the other end of which is connected to the fixing portion and / or the pushing portion.

[0009] Using the above technical solution, the guiding direction of the guide part is the same as the moving direction of the cutting machine. One end of the guide part is fixed to the housing, and the other end is fixed to the fixing part or the pushing part. The guide part can be a guide rail or a telescopic rod, etc. Setting the guide part can limit the direction of the cutting machine's forward and backward movement and improve the cutting efficiency.

[0010] Optionally, the pushing part includes a push rod and a first connecting rod, the first connecting rod being fixedly connected to the fixing part; the guiding part includes a fixing block and a second connecting rod, the first connecting rod and the second connecting rod being slidably sleeved together.

[0011] Using the above technical solution, the first connecting rod and the second connecting rod are slidably sleeved together to form a telescopic rod structure. By holding the push rod and applying force to push or pull the first connecting rod, the first connecting rod drives the fixed part forward or backward. Along the direction of movement of the cutting device, the second connecting rod extends or shortens relative to the first connecting rod, thereby driving the cutting machine forward or backward, limiting the forward and backward movement direction of the cutting machine, and improving cutting efficiency.

[0012] Optionally, the pushing assembly also includes a gripping rod, which is located at the rear end of the housing and close to the pushing part. The gripping rod is parallel to the push rod, and the push rod is located on the side of the gripping rod away from the hook part. When the non-cutting state is converted to the cutting state, the distance between the pushing part and the gripping rod decreases.

[0013] With the above technical solution, the gripping rod is connected to the housing, and the push rod is located on the side of the gripping rod away from the hook. The push rod and the gripping rod are set parallel to each other. During operation, the operator can hold both the push rod and the gripping rod with one hand at the same time. At this time, the position of the gripping rod remains stationary, and by applying force, the push rod moves forward and closer to the gripping rod. This process can be completed with one hand, that is, the gripping rod is designed to facilitate one-handed operation by the operator. One hand can hold the railing, and the other hand can control the distance between the gripping rod and the push rod, thereby controlling the working status of the cutting machine.

[0014] Optionally, a first limiting block is provided on the housing near the hook side, and when the pushing part is pushed forward to the first length, the fixing part and the first limiting block abut against each other.

[0015] Using the above technical solution, the first limiting block is set at the front end of the inner side of the housing. When the pushing part is pushed forward to the first length, the fixing part abuts against the first limiting block to prevent the pushing part from pushing the cutting machine excessively and causing the cutting machine to accidentally touch the hook part.

[0016] Optionally, a second limiting block is provided on the housing near the pushing part. When the pushing part pulls the fixing part backward to the second length, the fixing part and the second limiting block abut against each other.

[0017] Using the above technical solution, the second limiting block is set at the rear end of the housing, between the pushing part and the fixing part. Setting the second limiting block can prevent the pushing part from pulling back the fixing part beyond the second length, causing the fixing part to drive the cutting machine to retreat too much, resulting in the separation between the mechanisms or instability of the device.

[0018] Optionally, the opening faces the front side of the housing, and the receiving groove is arc-shaped.

[0019] With the above technical solution, the opening faces the front side of the shell, and the shape of the receiving groove is arc-shaped. That is, the railing enters the receiving groove from the front side opening and slides along the arc-shaped receiving groove until it abuts against the connection between the shell and the hook part, ensuring that the railing will not easily come out and is fixed more stably.

[0020] Optionally, an opening is provided on the upper part of the housing.

[0021] By adopting the above technical solution, the opening at the top of the housing can better control the switch of the cutting machine. Furthermore, if the cutting machine is too large, the opening can be made to accommodate various models of cutting machines.

[0022] Optionally, a reinforcing part is provided on the upper part of the housing on the side of the opening closest to the opening.

[0023] With the above technical solution, the upper part of the shell near the opening is not completely connected to the opening. A reinforcing part is also provided between the opening and the opening to facilitate the railing to abut, and to strengthen the shell at the cut point, thus ensuring the safety of the operation process.

[0024] Preferably, the handle is provided with an elastic friction element that is easy to grip, and the elastic friction element is provided with a friction pattern.

[0025] The beneficial effects of this application are: (1) the position of the object to be cut is fixed, which facilitates the cutting operation; (2) the disassembly and assembly method is simple and the disassembly and assembly efficiency is high; (3) it can be operated with one hand.

Detailed Implementation

[0028] The present application will now be further described with reference to the accompanying drawings and specific embodiments.

[0029] This utility model discloses an auxiliary tool for breaking into burglar bars, such as... Figure 1 , Figure 2 As shown, the device includes a housing 10; a cutting machine 20, which is slidably connected to the housing 10; and a hook portion 30, which is disposed at the front end of the housing 10 and is disposed opposite to the cutting machine 20. An opening 41 and a receiving groove 40 connected to the opening 41 are formed between the housing 10 and the hook portion 30. When the device is in a cutting state, the cutting part of the cutting machine 20 enters the receiving groove 40; when the device is in a non-cutting state, the cutting part of the cutting machine 20 exits the receiving groove 40.

[0030] The cutting machine 20 is the main body of the cutting device, and the cutting part refers to the part of the cutting machine 20 specifically used for cutting, such as the rotating cutting blade. In specific implementation, the cutting machine 20 is equipped with a housing 10, and a hook part 30 is provided at the front end of the housing 10. The hook part 30 is fitted onto the railing of the security window, and the railing enters the receiving groove 40 through the opening 41, so that the railing will not easily fall out. After the railing is fixed, when cutting is required, the cutting machine 20 is pushed forward, and the cutting part cuts the railing. The housing 10 and the hook part 30 fix the position of the cutting device and the railing, avoiding slippage during the cutting process, improving cutting efficiency, and ensuring safety during the cutting process.

[0031] In one embodiment, such as Figure 1 and Figure 3 As shown, the anti-theft window breaking auxiliary tool also includes a pushing component 50. The pushing component 50 includes a fixing part 51 and a pushing part 52. The fixing part 51 is slidably connected to the housing 10, and the cutting machine 20 is fixed to the fixing part 51. The pushing part 52 is fixedly connected to the fixing part 51, and the pushing part 52 pushes the fixing part 51 to slide along the housing 10.

[0032] In specific implementation, preferably, the cutting machine 20 is fixed to the fixing part 51, such as... Figure 3As shown, a through hole is provided in the middle of the fixing part 51, and the tail of the cutting machine 20 is fixed to the through hole. This connection can be achieved through snap-fit ​​or interference fit. The pushing part 52 is fixedly connected to the fixing part 51, either by welding or snap-fit. The pushing part 52 can be connected to either side of the fixing part 51 or to the end face near the pushing part 52; this is not limited here. The fixing part 51 is slidably connected to the inside of the housing 10. This slidable connection can be achieved by using a track or a telescopic rod. In operation, the pushing part 52 pushes the fixing part 51, causing the fixing part 51 to slide relative to the housing 10, thereby driving the cutting machine 20 to move forward or backward for cutting.

[0033] Preferably, although the cutting machine 20 can be pushed forward or pulled back by hand, the cutting device will generate strong vibrations during the cutting process, which can easily cause numbness in the hand. The pushing component 50 can effectively reduce the vibration transmitted to the hand, extend the operator's working time, and improve the safety of the cutting process.

[0034] In one embodiment, the pushing component 50 further includes a guide portion 53, one end of which is fixed to the housing 10, and the other end is connected to the fixing portion 51 and / or the pushing portion 52. Specifically, the guiding direction of the guide portion 53 is the same as the moving direction of the cutting machine 20. One end of the guide portion 53 is fixed to the housing 10, and the other end is fixed to the fixing portion 51 or the pushing portion 52. The guide portion 53 can be a guide rail, a telescopic rod, or the like. Providing the guide portion 53 can limit the direction of the cutting machine 20's forward and backward movement, thereby improving cutting efficiency.

[0035] In one embodiment, the pushing part 52 includes a push rod 522 and a first connecting rod 521, the first connecting rod 521 being fixedly connected to the fixing part 51; the guiding part 53 includes a fixing block 531 and a second connecting rod 532, the first connecting rod 521 and the second connecting rod 532 being slidably sleeved together.

[0036] In specific implementation, two first connecting rods 521 are provided, respectively located on both sides of the fixed part 51. A push rod 522 is connected to the end of the first connecting rod 521 away from the fixed part 51. One end of the guide part 53 and the second connecting rod 532 are fixedly connected to the housing 10 through the fixing block 531, and the other end is slidably sleeved with the first connecting rod 521. The first connecting rod 521 and the second connecting rod 532 are slidably sleeved to form a telescopic rod structure. By holding the push rod 522 and applying force to push or pull the first connecting rod 521, the first connecting rod 521 drives the fixed part 51 forward or backward. Along the direction of movement of the cutting device, the second connecting rod 532 extends or shortens relative to the first connecting rod 521, thereby driving the cutting machine 20 forward or backward.

[0037] In one embodiment, the pushing assembly 50 further includes a gripping rod disposed at the rear end of the housing 10. The gripping rod is disposed near the pushing part 52 and is arranged parallel to the push rod 522. The push rod 522 is located on the side of the gripping rod away from the hook part 30. When the non-cutting state is converted to the cutting state, the distance between the pushing part 52 and the gripping rod decreases.

[0038] Specifically, the grip rod is connected to the housing 10 via a third connecting rod. The push rod 522 is located on the side of the grip rod away from the hook portion 30. The push rod 522 is parallel to the grip rod. During operation, the operator can hold both the push rod 522 and the grip rod with one hand simultaneously. At this time, the position of the grip rod remains stationary, and by applying force, the push rod 522 moves forward and closer to the grip rod. This process can be completed with one hand, meaning the grip rod is designed to facilitate one-handed operation. The operator can hold onto the railing with one hand and control the distance between the grip rod and the push rod 522 with the other hand, thereby controlling the working state of the cutting machine 20.

[0039] In one embodiment, such as Figure 2 and Figure 4 As shown, the housing 10 near the hook side is provided with a first limiting block. When the pushing part 52 is pushed forward to the first length, the fixing part 51 and the first limiting block abut against each other.

[0040] When the pushing part 52 is pushed to the first length, the cutting machine 20 will not cut to the hook part 30.

[0041] Specifically, the first limiting block is located at the front end of the inner side of the housing 10. When the pushing part 52 is pushed forward to the first length, the fixing part 51 abuts against the first limiting block to prevent the pushing part 52 from pushing the cutting machine 20 excessively, causing the cutting machine 20 to accidentally touch the hook part 30.

[0042] In one embodiment, a second limiting block is provided on the housing 10 near the pushing part 52. When the pushing part 52 pulls the fixing part 51 backward to a second length, the fixing part 51 and the second limiting block abut against each other. The second length refers to the maximum backward length of the fixing part 51.

[0043] Specifically, the second limiting block is located at the rear end of the housing 10, between the pushing part 52 and the fixing part 51. The second limiting block can prevent the pushing part 52 from pulling back the fixing part 51 beyond the second length, causing the fixing part 51 to drive the cutting machine 20 to retreat too much, resulting in the separation between the mechanisms or instability of the device.

[0044] In one embodiment, the opening 41 faces the front side of the housing 10, and the receiving groove 40 is arc-shaped.

[0045] Specifically, the opening 41 faces the front side of the housing 10, and the receiving groove 40 is arc-shaped. That is, the railing enters the receiving groove 40 from the front side opening 41 and slides along the arc-shaped receiving groove 40 until it abuts against the connection between the housing 10 and the hook part 30, ensuring that the railing will not easily come out and is fixed more stably.

[0046] In one embodiment, an opening is provided on the upper part of the housing 10. Specifically, the opening 41 on the upper part of the housing 10 can better operate the switch of the cutting machine 20, and if the cutting machine 20 is too large, it can be made to extend through the opening, and it can also be adapted to various models of cutting machines 20.

[0047] In one embodiment, such as Figures 1 to 4 As shown, a reinforcing part 71 is provided on the upper part of the housing 10 on the side of the opening near the opening 41. The upper part of the housing 10 near the opening 41 is not completely connected to the opening.
