Description

Technical Field

[0001] The utility model belongs to the field of mobile terminal equipment, and in particular relates to a bridge inspection handheld terminal. Background Art

[0002] During operation, bridges are affected by the natural environment and vehicles. As they are used for a long time, they will experience various conditions such as aging, cracking, and steel bar corrosion. In order to promptly detect damage and risks to bridges, regular inspections are required to ensure the safety of bridges, and handheld terminals are required during the inspection process.

[0003] A Chinese patent with publication number CN209069213U discloses a mobile terminal device dedicated to a bridge construction site, whose structure includes a handle, a controller, a button, a distance measuring device and a wireless transmission device. The utility model is a mobile terminal device dedicated to a bridge construction site, and its beneficial effect is that in order to solve the problem that the construction distance width of the bridge construction site cannot be measured, resulting in a single functionality, a distance measuring device is provided, and the laser sensor is powered to work, emitting a laser pulse, and the laser is scattered in all directions after being reflected by the target, and part of the scattered light returns to the laser sensor. The laser sensor records and processes the time from the emission of the light pulse to the return and reception. Next, after the single-chip microcomputer chip at the upper end of the first circuit board processes the data, the controller controls the buzzer to broadcast and the display screen to display the distance data, thereby achieving the beneficial effect of being able to measure the construction distance width of the bridge construction site and increasing the diversity of functions.

[0004] In the above-mentioned comparative document, a mobile terminal device dedicated to a bridge construction site will cause fatigue to the inspectors if they hold the handle for a long time during use, which can easily cause the device to slip to the ground due to fatigue, thus causing damage to the device.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0028] One aspect of the application of this embodiment is: when in use, the anti-falling component is tied to the wrist of the inspector, who then holds the handle 18 and presses the driving component until the driving component is fixed by the limiting component. The driving component will drive the elastic belt 17 to move toward the handle 18, so that the elastic belt 17 and the handle 18 fix the inspector's hand, thereby avoiding the problem of the device sliding to the ground due to fatigue and causing damage to the device. When the device is not in use, the device can be clamped on the belt through the buckle 24, which increases the portability of the device.

[0029] See also Figure 1-4 As shown, a limiting through groove 4 is provided on one side of the shell 3 of this embodiment, and the driving assembly includes a main driving member and an auxiliary driving member installed in the shell 3. A fixing rod 25 is installed at the bottom of the inner cavity of the shell 3, and a gear 26 is rotatably connected to the side of the fixing rod 25. The main driving member includes a main limiting plate 7 installed in the shell 3, and a main limiting groove 8 is provided on one side of the main limiting plate 7. A main rack 9 is slidably fitted in the main limiting groove 8, and a first spring 10 is installed between the main rack 9 and the main limiting groove 8, and the main rack 9 is meshed with the gear 26; a fixing block 16 is installed on the main rack 9.

[0030] See also Figure 1-4 As shown, a secondary limiting groove 12 is provided on one side of the secondary limiting plate 11 of the present embodiment, a secondary rack 13 is slidably fitted in the secondary limiting groove 12, a pressing block 14 is installed on one side of the secondary rack 13, a square groove 15 is provided on one side of the secondary limiting plate 11, a clamping groove 31 is provided on one side of the secondary rack 13, and the secondary rack 13 is meshed with the gear 26; half of the secondary rack 13 is set as a smooth surface, and the other half is set with teeth.

[0031] Through the set driving assembly, when the elastic band 17 and the handle 18 need to fix the inspector's hands, by pressing the pressing block 14, the pressing block 14 drives the auxiliary rack 13 to slide in the auxiliary limit groove 12, and the auxiliary rack 13 will drive the gear 26 to rotate during the sliding process, and the rotation of the gear 26 will drive the main rack 9 to move, and the movement of the main rack 9 will drive the fixed block 16 to move, and the movement of the fixed block 16 will drive the elastic band 17 to gradually approach the handle, so that the elastic band 17 and the handle 18 fix the inspector's hands to avoid the device from being damaged due to hand slippage.

[0032] See also Figure 1-5 As shown, the limit assembly of this embodiment includes a block 27 that slides in the installation groove 6, a pull rod 28 is installed on one side of the block 27, one end of the pull rod 28 passes through the shell 3, and a pull ring 29 is installed on the end of the pull rod 28 located outside the shell 3, and a second spring 30 is installed between the block 27 and the installation groove 6; the block 27 is adapted to the slot 31.

[0033] By means of the limit assembly, when the pressing block 14 drives the auxiliary rack 13 to slide in the auxiliary limit groove 12, the auxiliary rack 13 will squeeze the block 27, so that the block 27 slides into the installation groove 6. When the slot 31 of the auxiliary rack 13 moves to the position of the square slot 15, under the action of the second spring 30, the block 27 is inserted into the slot 31, thereby fixing the position of the elastic band 17. When the elastic band 17 and the handle 18 are no longer needed to fix the hands of the inspectors, the pull ring 29 is pulled, and the pull ring 29 drives the pull rod 28 to move, and the pull rod 28 drives the block 27 to move, so that the block 27 is away from the slot 31. Then, under the action of the first spring 10, the main rack 9 is reset, and the reset of the main rack 9 will drive the reset of the elastic band 17. At the same time, the reset of the main rack 9 will drive the gear 26 to rotate, and the rotation of the gear 26 drives the auxiliary rack 13 to reset.

[0034] See also Figure 1-2 As shown, the anti-falling assembly of this embodiment includes a fixing ring 20 installed at the bottom of the handle 18, a connecting ring 21 is provided inside the fixing ring 20, an elastic rope 22 is installed on the connecting ring 21, and a wrist strap 23 is installed at one end of the elastic rope 22; the wrist strap 23 is an elastic rubber band.

[0035] By setting up the anti-falling component, the wristband 23 is fixed on the wrist during use. When the hand slips and causes the device to fall out of the hand, the elastic rope 22 can prevent the device from falling to the ground and being damaged.
