Description

Technical Field

[0001] The utility model relates to the technical field of length detection equipment, in particular to a portable length detection device. Background Technique

[0002] A length detection device is a tool that compares the measured length with a known length to obtain a measurement result, abbreviated as a measuring tool. Length measuring tools include gauges, measuring tools, and measuring instruments, etc. The most widely used, common, and convenient length detection device on the market is a tape measure.

[0003] Since the top fixed hook structure of the tape measure is relatively simple and easy to slip when measuring the distance between round rods, another staff member is required to press and fix it at the other end, reducing the practicality. The tape measure is mostly carried by pulling a rope, but when measuring on a construction site, data needs to be recorded. One hand needs to hold a pen and the other hand needs to hold a recording board, which is inconvenient to carry the tape measure and reduces the portability. For this reason, we propose a portable length detection device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a portable length detection device to solve the problems of easy slipping when measuring the distance between round rods and inconvenient carrying of the tape measure mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A portable length detection device, including a protective shell and a fixed disk. The fixed disk is located below the protective shell. A tape measure is movably installed in the inner cavity of the protective shell. The end of the tape measure is fixedly connected with an installation block. A screw rod is rotatably connected to the inner cavity of the installation block. The screw rod penetrates through the inner cavity of the installation block and extends to the outside of the installation block. A moving block is screwed on the left side of the outer side wall of the screw rod. A through groove is opened on the rear side wall of the installation block. A moving clamping block is fixedly connected to the rear side wall of the moving block. The moving clamping block penetrates through the through groove and extends to the outside of the installation block. A fixed clamping block is fixedly connected to the right side of the rear side wall of the installation block. A connecting block is fixedly connected to the bottom of the protective shell. Installation plates are fixedly connected to the lower sides of the left and right side walls of the connecting block. A limiting rod is fixedly connected to the top of the installation plate. A connecting groove is opened on the top of the fixed disk. The connecting block is clamped in the inner cavity of the connecting groove. A turntable is rotatably connected to the bottom of the inner cavity of the connecting groove. Telescopic rods are fixedly connected to the left and right sides of the top of the turntable. A placement plate is fixedly connected to the top of the telescopic rod. A return spring is fixedly connected to the bottom of the placement plate. The return spring is fixedly connected with the turntable. Belts are fixedly connected to the left and right sides of the bottom of the fixed disk.

[0024] Please refer to again Figures 1-5 As shown, a tape measure 110 is movably installed in the inner cavity of the protective shell 100. The tape measure 110 is used to measure distances. A mounting block 120 is fixedly connected to the end of the tape measure 110. The mounting block 120 is used to mount a screw rod 121. A screw rod 121 is rotatably connected to the inner cavity of the mounting block 120. The screw rod 121 penetrates through the inner cavity of the mounting block 120 and extends to the outside of the mounting block 120. The screw rod 121 is used to drive a moving block 122 to move. A moving block 122 is screwed on the left side wall of the outer side wall of the screw rod 121. A through groove 130 is opened on the rear side wall of the mounting block 120. A moving clamping block 131 is fixedly connected to the rear side wall of the moving block 122. The moving clamping block 131 penetrates through the through groove 130 and extends to the outside of the mounting block 120.

A limiting rod 142 is fixedly connected to the top of the mounting plate 141. The limiting rod 142 is used to limit the connecting block 140;

[0025] Please refer to again Figures 1-4 As shown, the fixed disk 200 is located below the protective shell 100. Specifically, the fixed disk 200 is mutually clamped with the protective shell 100 through the connecting block 140. A connecting groove 210 is opened on the top of the fixed disk 200. The connecting block 140 is clamped in the inner cavity of the connecting groove 210. A turntable 211 is rotatably connected to the bottom of the inner cavity of the connecting groove 210. The turntable 211 is used to drive a placing plate 220 to rotate. Telescopic rods 212 are fixedly connected to the left and right sides of the top of the turntable 211. The telescopic rods 212 are used to guide the placing plate 220. The top ends of the telescopic rods 212 are fixedly connected to the placing plate 220. The placing plate 220 is used to prevent the connecting block 140. A reset spring 221 is fixedly connected to the bottom of the placing plate 220.
