Technical Field

[0001] The invention relates to the technical field of safety detection equipment, in particular to a handheld device dedicated for on-site verification of high-reliability safety evaluation. Background Art

[0002] During the safety evaluation process, it is necessary to conduct an on-site survey of the project being evaluated. The survey content mainly includes: project site selection; external and internal fire protection distances of the project; fire resistance level of project buildings; seismic resistance level of project buildings; whether the production process and equipment of the project meet the national safety production standards; dangerous and harmful factors during the construction, operation and demolition of the project, etc. During the on-site survey of the safety evaluation, tools such as distance measurement, photography, video, text recording, temperature measurement, positioning, and lighting are required. The items required to be carried are relatively numerous, and the recording forms are various. After the survey, it is necessary to sort out and organize them, which is not conducive to the rapid and effective on-site survey work, nor is it conducive to the rapid development of subsequent work. Therefore, a special handheld device for on-site verification of safety evaluation was born. It can survey the site through measuring equipment such as cameras and laser rangefinders, and transmit and process the data of on-site survey through acquisition modules, data processing modules and transmission modules, greatly improving the efficiency of survey and evaluation operations.

A protective shell 7 is arranged inside the shell 1, and the module body 6 is arranged inside the protective shell 7. A shock-absorbing layer 8 is arranged inside the protective shell 7. Damping springs 9 are installed on the surfaces of the left and right sides and the bottom of the protective shell 7, and the end of the damping spring 9 away from the protective shell 7 is fixedly installed with the inner wall of the shell 1. A protective cover 10 is arranged above the shell 1. Connecting plates 11 are bolted on the left and right sides of the bottom of the protective cover 10. A fixing hole 13 is penetrated on the surface of the connecting plate 11. A through groove 12 is penetrated on the left and right sides of the top of the shell 1, and the connecting plate 11 is slidably connected to the inner wall of the through groove 12. The inner cavity of the shell 1 The left and right sides of the shell 1 are provided with fixing mechanisms 14, the left and right sides of the shell 1 are respectively provided with a first strap 15 and a second strap 16, the ends of the first strap 15 and the second strap 16 away from the shell 1 are respectively sewn with a thorny Velcro 17 and a soft Velcro 18, and a supporting shock-absorbing mechanism 19 is arranged at the rear of the inner cavity of the shell 1. The handheld device has a shock-absorbing protection function, and can also be effectively fixed to the hands of workers to prevent the handheld device from falling off from the hands of workers during the investigation process, which solves the problem that some existing handheld devices cannot be effectively fixed to the hands of workers and lack shock-absorbing protection measures. Under complex conditions at the investigation site, once the handheld device falls off from the hand, it is easy to cause damage to the more fragile module components inside the handheld device. The handheld device can also seal and protect the camera and the ranging head when idle, thereby improving the protection and reliability of the handheld device.

[0026] In this embodiment, the fixing mechanism 14 includes a fixing block 141, an adjusting bolt 142 and a threaded hole 143. The number of the threaded holes 143 is 2 and they are respectively opened on the surfaces of the left and right sides of the shell 1. The adjusting bolt 142 is threadedly connected to the inner wall of the threaded hole 143. The fixing block 141 is welded to the opposite end of the adjusting bolt 142, and the fixing block 141 is used in conjunction with the fixing hole 13. Through the setting of the fixing block 141, the adjusting bolt 142 and the threaded hole 143, their coordinated use can fix the fixing hole 13 and the connecting plate 11, so that workers can install the protective cover 10.

[0027] In this embodiment, the fixing block 141 is cylindrical as a whole, and the outer diameter of the fixing block 141 is larger than the inner diameter of the threaded hole 143. This design enables the fixing block 141 to rotate inside the fixing hole 13 to prevent the fixing block 141 from being unable to rotate, thereby causing the adjusting bolt 142 to be unable to rotate.

[0028] In this embodiment, the opposite end of the adjusting bolt 142 is fixedly connected to the knob 21, and the surface of the knob 21 is integrated with anti-slip grooves, and the anti-slip grooves are evenly distributed on the surface of the knob 21. The setting of the knob 21 makes it convenient for workers to rotate and adjust the adjusting bolt 142.

[0029] In this embodiment, the support shock-absorbing mechanism 19 includes a shock-absorbing spring 191, a vertical plate 192 and a ball 193. The two ends of the shock-absorbing spring 191 are fixedly installed on the inner wall of the shell 1 and the back of the vertical plate 192 respectively. The ball 193 is installed on the surface of the vertical plate 192 away from the shock-absorbing spring 191, and the ball 193 is rollingly connected to the back of the protective shell 7. Through the arrangement of the shock-absorbing spring 191, the vertical plate 192 and the ball 193, their coordinated use can provide additional support points for the protective shell 7, increase its stability, and also provide shock-absorbing protection for the protective shell 7 and the module body 6 inside it, thereby improving the protectiveness of the handheld device.

[0030] In this embodiment, a telescopic rod 20 is bolted to the back of the vertical plate 192, and the other end of the telescopic rod 20 is bolted to the inner wall of the shell 1. Through the setting of the telescopic rod 20, it can provide an additional support point for the vertical plate 192 to prevent the vertical plate 192 from bending the shock-absorbing spring 191 under the action of its own gravity and affecting the use of the shock-absorbing spring 191.

[0031] In this embodiment, the balls 193 are evenly spaced from top to bottom, and the number of telescopic rods 20 is 2 groups and they are arranged up and down. By designing that the balls 193 are evenly spaced from top to bottom, the force points of the protective shell 7 are made more uniform. At the same time, the telescopic rods 20 are arranged up and down to distribute the support points of the vertical plate 192, thereby increasing the stability of the vertical plate 192.

[0032] In this embodiment, hooks 22 are bolted to the left and right sides of the top of the shell 1, and the hooks 22 are made of elastic plastic. Through the setting of the hooks 22, it is convenient for workers to hang the handheld device on the surface of the belt for carrying.

[0033] In this embodiment, the first strap 15 and the second strap 16 are both made of elastic fabrics, and the area of ​​the thorny Velcro 17 is smaller than the area of ​​the soft Velcro 18. By designing that the first strap 15 and the second strap 16 are both made of elastic fabrics, the first strap 15 and the second strap 16 have ductility. At the same time, the area of ​​the thorny Velcro 17 is designed to be smaller than the area of ​​the soft Velcro 18, which can improve the fixing surface of the Velcro.

[0034] In this embodiment, the material of the shock-absorbing layer 8 is shock-absorbing rubber, and the thickness of the shock-absorbing layer 8 is 0.5-1mm. By designing the shock-absorbing layer 8 to be made of shock-absorbing rubber, the shock-absorbing rubber can utilize the characteristics of rubber to eliminate mechanical vibrations to achieve shock absorption, noise reduction, and reduce the harm caused by impact, thereby improving the protectiveness of the handheld device.

[0035] Working principle: When in use, first hold the shell 1 with one hand, then move the first strap 15 or the second strap 16 with the other hand, and make the two straps wrap around the hand holding the shell 1, and then fix the first strap 15 and the second strap 16 to each other through the thorny Velcro 17 and the soft Velcro 18. At this time, the handheld device and the worker's hand are in a fixed state to prevent it from falling off the hand during the investigation. Then the worker can use the other hand to operate the handheld device keyboard 3, and use the camera and the rangefinder to investigate the site; due to the setting of the protective shell 7, the shock-absorbing layer 8 and the damping spring 9, the handheld device can provide shock-absorbing protection for the module components, which makes the fragile module components not easily damaged by external impact, greatly improving the protection of the handheld device When the handheld device is idle, the protective cover 10 can be picked up and the connecting plate 11 can be aligned with the through slot 12, and then the protective cover 10 can be moved to make the connecting plate 11 pass through the through slot 12 and enter the interior of the housing 1, and then the knobs 21 on the left and right sides are rotated, which drives the adjusting bolts 142 to start rotating. At this time, the adjusting bolts 142 on the left and right sides make relative motion under the action of the threads, which makes the fixing block 141 make relative motion together until the knob 21 sticks to the surface of the housing 1, and then the knob 21 can be stopped. At this time, the fixing block 141 passes through the fixing hole 13, which makes the connecting plate 11 and the protective cover 10 both in a fixed state, and the protective cover 10 can seal and protect the camera body 4 and the rangefinder body 5, so that they are not easily damaged when idle.
