Description

Technical Field

[0001] This utility model belongs to the field of fire safety inspection technology, specifically relating to a multifunctional tool for fire safety inspection. Background Technology

[0002] In fire safety inspections, laser rangefinders are a very practical tool, primarily used for quickly and accurately measuring spatial parameters such as distance, height, and width. They help inspectors efficiently measure the dimensions of buildings, fire safety facilities, and evacuation routes to ensure compliance with fire safety standards.

[0003] A portable tool for fire supervision and inspection is disclosed in the utility model patent with patent authorization announcement number CN205026627U. It includes two parts: a two-way telescopic rangefinder slot and a fire inspection flashlight clip. The feature is that a metal gasket is added to one side of the two-way telescopic rangefinder slot, and it is fixedly connected to the high-intensity flashlight clip with screws and nuts.

[0004] However, existing fire safety inspection tools also have certain shortcomings. Although existing fire safety inspection tools use components such as brackets to mount and use laser rangefinders, the fixed angle of the brackets requires operators to manually rotate and adjust the angle of the laser rangefinder, resulting in a limited versatility of the laser rangefinder. Summary of the Invention

[0005] The purpose of this utility model is to provide a multi-functional tool for fire safety inspection, which solves the problem that existing fire safety inspection tools, although using components such as a mounting bracket to house the laser rangefinder, require manual rotation by operators to adjust the angle of the laser rangefinder due to the fixed angle of the mounting bracket, resulting in a weak multi-functionality of the laser rangefinder.

[0006] To achieve the above objectives, this utility model provides a multifunctional tool for fire safety inspection, including a support cylinder. The upper end of the support cylinder contacts a support shell. A laser rangefinder is slidably connected to the inner wall of the support shell. An auxiliary lighting lamp is fixedly installed on the right end of the support shell. An insertion rod is slidably connected to the inner wall of the support shell and is slidably connected to the laser rangefinder. A connecting plate is fixedly connected to the left end of the insertion rod. A spring is provided on the outer side of the insertion rod. An adjustment mechanism is provided inside the support cylinder.

[0007] The principle of this utility model is as follows: by pulling the connecting plate away from the support shell, the insertion rod slides along the inner wall of the support shell. Once the spring deforms, it pushes the laser rangefinder into the support shell, causing the positioning block to slide into the support shell to position the laser rangefinder. Then, the connecting plate is released, and the spring returns to its original deformation, pulling the insertion rod to insert the laser rangefinder and limit its position, thus stabilizing the laser rangefinder. This facilitates quick installation and use by operators. In addition, with the addition of auxiliary lighting, it can provide auxiliary illumination when using the laser rangefinder.

[0008] A micro motor drives the output shaft to rotate, which in turn rotates the rotating disk and the support shell. This allows for adjustment of the laser rangefinder's detection angle. As the rotating disk rotates, it also rotates the guide rod, which in turn moves the positioning rod. Under pressure from the inner wall of the positioning hole, the positioning rod slides along the guide rod surface. Spring two deforms, eventually causing the positioning rod to disengage from the positioning hole. Under the action of force, the positioning rod slides along the inner wall of the support cylinder. When the positioning rod slides into the next positioning hole, spring two returns to its original shape, allowing the positioning rod to re-insert into the positioning hole, limiting the rotation of the rotating disk and thus positioning the laser rangefinder. This prevents unnecessary deflection of the support shell caused by inertia and centrifugal force when the micro motor stops operating.

[0009] The beneficial effects of this utility model are as follows: This solution pushes the laser rangefinder into the support shell, allowing the positioning block to slide into the support shell for positioning. The insertion rod, spring, and other structures provide insertion and limiting for the laser rangefinder, facilitating quick installation. Combined with auxiliary lighting, it illuminates the safe distance between electrical components during fire safety inspections, enhancing the tool's versatility. The micro-motor and rotating disk drive the support shell to rotate the laser rangefinder, allowing for adaptive adjustment of the detection orientation and further enhancing the tool's versatility. The positioning hole and positioning rod limit the rotation of the rotating disk, thus positioning the laser rangefinder's deflection angle.

[0010] Furthermore, a positioning block is fixedly connected to the right end of the laser rangefinder. The positioning block is slidably connected to the support shell. By setting the positioning block, the laser rangefinder can be positioned for use.

[0011] Furthermore, one end of the spring is welded to the connecting disc, and the other end of the spring is welded to the support shell. The connecting disc can be connected and used through the setting of the spring.

[0012] Furthermore, the adjustment mechanism includes a micro motor. The micro motor is fixedly installed on the bottom inner side of the support cylinder. The output shaft of the micro motor is fixedly connected to a rotating disk. A positioning hole is provided on the inner side wall of the support cylinder. A guide rod is fixedly connected to the inner wall of the rotating disk. A movable piece is slidably sleeved on the outer side of the guide rod. The movable piece is slidably connected to the rotating disk. A positioning rod is fixedly connected to the end face of the movable piece away from the micro motor. The positioning rod is slidably connected to the positioning hole. An end block is fixedly connected to the lower end of the rotating disk. Driven by the micro motor, the support shell can drive the laser rangefinder to rotate. With the use of the positioning hole and positioning rod, the laser rangefinder can be rotated and positioned.

[0013] Furthermore, the rotating disk is rotatably connected to the support cylinder, and the rotating disk is fixedly connected to the support shell. The support shell can be installed by means of the rotating disk.

[0014] Furthermore, multiple positioning holes are provided, and these positioning holes are arranged in a circular array on the support cylinder. The positioning holes facilitate the use of positioning rods for snap-fit ​​connection.

[0015] Furthermore, a second spring is welded to the left end of the end block, and the other end of the second spring is welded to the movable piece. The movable piece can be connected and used through the setting of the second spring. Attached Figure Description

Detailed Implementation

[0023] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides a multi-functional tool for fire safety inspection, including a support cylinder 1, a support shell 2 in contact with the upper end of the support cylinder 1, a laser rangefinder 3 slidably connected to the inner wall of the support shell 2, an auxiliary lighting lamp 4 fixedly installed on the right end of the support shell 2, an insertion rod 6 slidably connected to the inner wall of the support shell 2, the insertion rod 6 slidably connected to the laser rangefinder 3, a connecting plate 7 fixedly connected to the left end of the insertion rod 6, and a spring 8 provided on the outer side of the insertion rod 6.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a positioning block 5 is fixedly connected to the right end of the laser rangefinder 3. The positioning block 5 is slidably connected to the support shell 2. The laser rangefinder 3 can be positioned by the positioning block 5. One end of the spring-8 is welded to the connecting plate 7, and the other end of the spring-8 is welded to the support shell 2. The connecting plate 7 can be connected by the spring-8.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the support cylinder 1 is equipped with an adjustment mechanism 9, which includes a micro motor 91. The micro motor 91 is fixedly installed on the bottom inner side of the support cylinder 1. The output shaft of the micro motor 91 is fixedly connected to a rotating disk 92. A positioning hole 93 is opened on the inner wall of the support cylinder 1. A guide rod 94 is fixedly connected to the inner wall of the rotating disk 92. A movable piece 95 is slidably sleeved on the outer side of the guide rod 94. The movable piece 95 is slidably connected to the rotating disk 92. A positioning rod 96 is fixedly connected to the end face of the movable piece 95 away from the micro motor 91. The positioning rod 96 is slidably connected to the positioning hole 93. An end block 97 is fixedly connected to the lower end of the rotating disk 92. Driven by the micro motor 91, the support shell 2 can drive the laser rangefinder 3 to rotate. With the use of the positioning hole 93 and the positioning rod 96, the laser rangefinder 3 can be rotated and positioned.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the rotating disk 92 is rotatably connected to the support cylinder 1, and the rotating disk 92 is fixedly connected to the support shell 2. The support shell 2 can be installed by the rotating disk 92. Multiple positioning holes 93 are provided, and the multiple positioning holes 93 are arranged in a ring array on the support cylinder 1. The positioning holes 93 facilitate the use of the positioning rod 96 for snap-fit. A second spring 98 is welded to the left end of the end block 97. The other end of the second spring 98 is welded to the moving piece 95. The moving piece 95 can be connected by the second spring 98.

[0027] The specific implementation process of this utility model is as follows: By pulling the connecting plate 7 to move away from the support shell 2, the insertion rod 6 is driven to slide along the inner wall of the support shell 2, the spring 8 deforms, and then pushes the laser rangefinder 3 into the support shell 2, so that the positioning block 5 slides into the support shell 2 to position the laser rangefinder 3 for use. Then, the connecting plate 7 is released so that the spring 8 returns to its original deformation, so that the insertion rod 6 is pulled to insert the laser rangefinder 3, limiting the laser rangefinder 3 and making the laser rangefinder 3 stable, which facilitates the quick installation and use by operators. With the setting of the auxiliary lighting lamp 4, it can be used to provide auxiliary lighting when the laser rangefinder 3 is in use.

[0028] The output shaft is driven by a micro motor 91 to rotate, which in turn drives the rotating disk 92 to rotate, thereby rotating the support shell 2. This allows for adjustment of the detection angle of the laser rangefinder 3. When the rotating disk 92 rotates, it drives the guide rod 94 to rotate, which in turn moves the positioning rod 96. Under the pressure of the inner wall of the positioning hole 93, the positioning rod 96 slides along the surface of the guide rod 94. The second spring 98 deforms, eventually causing the positioning rod 96 to disengage from the positioning hole 93. Under the action of force, the positioning rod 96 slides along the inner wall of the support cylinder 1. When the positioning rod 96 slides into the next positioning hole 93, the second spring 98 returns to its original deformation, allowing the positioning rod 96 to insert into the positioning hole 93, limiting the rotation disk 92 and thus positioning the laser rangefinder 3. This prevents the support shell 2 from excessively deflecting under external forces such as inertia and centrifugal force when the micro motor 91 stops running.

[0029] This solution involves pushing the laser rangefinder 3 into the support shell 2, causing the positioning block 5 to slide into the support shell 2 for positioning the laser rangefinder 3. The insertion rod 6, spring 8, and other structures provide insertion and limiting for the laser rangefinder 3, facilitating rapid installation. Combined with the auxiliary lighting 4, it illuminates the safe distance between electrical components during fire safety inspections, enhancing the tool's versatility. The micro motor 91, rotating disk 92, and other structures drive the support shell 2 to rotate the laser rangefinder 3, allowing for adaptive adjustment of the detection orientation and further enhancing the tool's versatility. The positioning hole 93, positioning rod 96, and other structures limit the rotation of the rotating disk 92, thereby positioning the deflection angle of the laser rangefinder 3.
