Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping devices, in particular to a fire engineering surveying and mapping device. Background Art

[0002] Fire engineering involves many aspects, including building design, fire equipment, fire alarm systems, fire extinguishing systems, evacuation plans and firefighter training. Fire engineers are responsible for ensuring that buildings comply with relevant building regulations and fire safety standards and are able to provide quick and effective response measures when a fire occurs. Surveying and mapping devices are required during the construction of fire engineering.

[0003] A fire engineering surveying and mapping device is disclosed in a Chinese utility model patent with publication number CN219455102U, which belongs to the field of surveying and mapping technology. The device aims to solve the problems that the existing fire engineering surveying and mapping devices cannot ensure that the tower ruler is in a vertical state during operation, cannot stably support the tower ruler itself, are not convenient for detecting the installation spacing of fire pipes, and cannot adaptively adjust the detection spacing according to the installation spacing of fire pipes. The device comprises a tower ruler, and rotating rods are rotatably installed on the left and right sides and the rear side of the tower ruler, an inner rod is slidably installed inside the rotating rod, a support rod is fixedly connected to the bottom of the inner rod, a fixed plate is fixedly installed on the surface of the tower ruler, a slider is slidably installed inside the fixed plate, the slider is connected to the adjacent slider through a spring, and a mounting rod is installed inside the slider.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device maintains the tower ruler stable by means of three support rods. When the staff installs the tower ruler, the staff need to connect the three support rods to the ground in sequence. Since the three support rods are fixed to the inner rod, and the inner rod is slidably connected to the rotating rod, the staff need to manually maintain the support rods stable while connecting the support rods to the ground. The operation is relatively complicated, which is not conducive to improving the staff's user experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a fire engineering surveying and mapping device.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A fire engineering surveying and mapping device includes a device body, wherein sleeves are arranged on the three side walls of the device body, a sleeve rod is slidably arranged in the sleeve, a support rod is arranged on the bottom surface of the sleeve rod, a plurality of equally spaced limiting holes are arranged on the inner wall of the sleeve, a limiting groove is arranged on the side wall of the sleeve rod, and a limiting component for limiting the sleeve rod is arranged on the sleeve rod.

[0008] By adopting the above technical solution, when the staff needs to conduct surveying and mapping, the staff needs to move the device body to the target area and pull the support rod to make the sleeve rod slide along the extension direction of the sleeve. Then, when the staff stops sliding the support rod, the support rod remains stable under the action of the limit assembly. The staff only needs to make the support rod close to the ground and press the device body downward to connect the support rod with the ground, thereby reducing the operating difficulty of the staff and eliminating the need to manually keep the support rod stable, thereby improving the staff's user experience.

[0009] Furthermore, the limiting assembly includes a limiting rod slidably arranged in the limiting groove and a limiting spring with one end fixed on the side wall of the limiting rod away from the limiting hole, and the other end of the limiting spring is fixed on the inner wall of the limiting groove away from the limiting hole.

[0010] Furthermore, an inclined surface is provided on an edge where the bottom surface of the limiting rod intersects with the side wall thereof away from the limiting spring.

[0011] By adopting the above technical solution, when the staff stops moving the support rod, the limit rod is connected to the adjacent limit hole under the action of the limit spring, so that the limit rod remains stable under the action of the limit hole, thereby reducing the probability of displacement of the support rod of the device body caused by the staff pressing down.

[0012] Furthermore, a connecting rope is provided on the side wall of the limiting rod close to the limiting spring, and the other end of the connecting rope extends to the outside of the sleeve rod and is slidably connected.

[0013] Furthermore, a rotation groove is provided on the side wall of the sleeve rod, an annular plate is rotatably arranged in the rotation groove, and the inner wall of the annular plate is fixed to an end of the connecting rope away from the limiting rod.

[0014] By adopting the above technical solution, when the staff needs to adjust the position of the support rod, the staff only needs to rotate the annular plate to make one end of the connecting rope rotate with the annular plate, so that the limiting rod is separated from the limiting hole under the action of the connecting rope, thereby reducing the operating difficulty of the staff.

[0015] Furthermore, an accommodating groove for accommodating a connecting rope is provided on the inner wall of the rotating groove.

[0016] By adopting the above technical solution, the probability of the connecting rope getting stuck is reduced, thereby improving the stability of the device.

[0017] Furthermore, a magnet block is fixed on the side wall of the limiting rod away from the limiting spring, and an iron sheet is arranged on the inner wall of the limiting hole away from the limiting rod.

[0018] By adopting the above technical solution, when the limit rod is reset under the action of the limit spring, the limit rod gradually approaches the limit hole. At this time, the magnet block adsorbs the iron sheet, thereby reducing the probability of the limit rod getting stuck, thereby improving the user experience of the device.

[0019] Furthermore, an anti-skid layer for reducing the probability of slipping is provided on the side wall of the annular plate.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to conduct surveying, the staff needs to move the device body to the target area and pull the support rod to make the sleeve rod slide along the extension direction of the sleeve. Then, when the staff stops sliding the support rod, the support rod remains stable under the action of the limit assembly. The staff only needs to make the support rod close to the ground and press the device body downward to connect the support rod with the ground, thereby reducing the difficulty of operation for the staff, and there is no need to manually keep the support rod stable, thereby improving the staff's user experience;

[0022] 2. In the present application, when the staff stops moving the support rod, the limit rod is connected to the adjacent limit hole under the action of the limit spring, so that the limit rod remains stable under the action of the limit hole, thereby reducing the probability of displacement of the support rod of the device body caused by the staff pressing down;

[0023] 3. In the present application, when the staff needs to adjust the position of the support rod, the staff only needs to rotate the annular plate to make one end of the connecting rope rotate with the annular plate, so that the limit rod is separated from the limit hole under the action of the connecting rope, thereby reducing the difficulty of operation for the staff.

The sleeve 11 is a rectangular rod-shaped structure with an open bottom, and three sleeves 11 are provided and respectively arranged on three side walls of the device body 1. The sleeve rod 2 is a rectangular rod-shaped structure, and the sleeve rod 2 is slidably arranged in the sleeve 11. The support rod 21 is a rod-shaped structure, and the support rod 21 is arranged on the bottom surface of the sleeve rod 2.

[0031] A plurality of equally spaced limiting holes 3 are provided on the inner wall of the sleeve 11, a limiting groove 31 is provided on the side wall of the sleeve rod 2, and a limiting assembly 4 is provided on the sleeve rod 2 for limiting the sleeve rod 2, and the limiting assembly 4 comprises a limiting rod 41 and a limiting spring 42. The limiting rod 41 is a rectangular rod-shaped structure, and the limiting rod 41 is slidably provided in the limiting groove 31, and an inclined surface is provided on the edge where the bottom surface of the limiting rod 41 intersects with the side wall away from the limiting spring 42. One end of the limiting spring 42 is fixed on the side wall of the limiting rod 41 away from the limiting hole 3, and the other end of the limiting spring 42 is fixed on the inner wall of the limiting groove 31 away from the limiting hole 3.

[0032] When the staff stops moving the support rod 21, the limit rod 41 is connected to the adjacent limit hole 3 under the action of the limit spring 42, so that the limit rod 41 remains stable under the action of the limit hole 3, thereby reducing the probability of displacement of the support rod 21 caused by the staff pressing down on the device body 1.

[0033] One end of the connecting rope 5 is arranged on the side wall of the limiting rod 41 close to the limiting spring 42, and the other end of the connecting rope 5 extends to the outside of the sleeve rod 2 and is slidably connected. A rotation groove 51 is opened on the side wall of the sleeve rod 2, and the annular plate 6 is a plate-shaped structure with a circular cross section. The annular plate 6 is rotatably arranged in the rotation groove 51, and the inner wall of the annular plate 6 and the end of the connecting rope 5 away from the limiting rod 41 are fixed to each other.

[0034] When the staff needs to adjust the position of the support rod 21, the staff only needs to rotate the annular plate 6 to make one end of the connecting rope 5 rotate with the annular plate 6, so that the limiting rod 41 is separated from the limiting hole 3 under the action of the connecting rope 5, thereby reducing the operating difficulty of the staff.

[0035] In order to reduce the probability of the connecting rope 5 getting stuck, thereby improving the stability of the device, an accommodating groove 61 for accommodating the connecting rope 5 is opened on the inner wall of the rotating groove 51 .

At this time, the magnet block 7 adsorbs the iron sheet 8, thereby reducing the probability of the limiting rod 41 getting stuck, thereby improving the use experience of the device.

[0038] The use principle of a fire engineering surveying and mapping device in this embodiment is as follows: when the staff needs to conduct surveying and mapping, the staff needs to move the device body 1 to the target area and pull the support rod 21 to slide the sleeve rod 2 along the extension direction of the sleeve 11. Subsequently, when the staff stops sliding the support rod 21, the support rod 21 remains stable under the action of the limit assembly 4. The staff only needs to make the support rod 21 close to the ground and press the device body 1 downward to connect the support rod 21 with the ground, thereby reducing the operating difficulty of the staff and eliminating the need to manually keep the support rod 21 stable, thereby improving the staff's use experience.
