Technical Field
[0001] This utility model belongs to the field of positioning instruments, specifically relating to a rebar positioning instrument for bridge inspection. Background Technology
[0002] A rebar locator for bridge inspection is a device used to detect and locate rebar in concrete structures. It helps engineers and technicians accurately determine the location, quantity, and diameter of the rebar for structural assessment and maintenance.
[0003] When existing ultrasonic locators are used to inspect steel bars in bridges, the display screen and function buttons on typical ultrasonic locators are often exposed. When not in use, foreign objects can easily squeeze the screen or buttons. The screen and buttons on ultrasonic locators are also very fragile. After being pressed for a long time or repeatedly, they may malfunction or be damaged, which will greatly affect the service life of the ultrasonic locator.
[0004] Therefore, in response to the problem that the screen and buttons of existing ultrasonic locators are prone to accidental touches and damage when not in use, a rebar locator for bridge inspection has been developed. By adding a screen, button cover structure, two-way opening and closing adjustment structure and protrusion limiting structure to the ultrasonic locator, the service life of the screen and buttons on the ultrasonic locator can be improved, the comfort when holding it can be improved, and the flexibility of the protective cover during use can also be improved. Utility Model Content

An ultrasonic detector is fixedly connected to the lower end of the positioning instrument body, a microcomputer is fixedly connected to the front end of the positioning instrument body, a handheld bracket is fixedly connected to the upper end of the positioning instrument body, a threaded column is fixedly connected to the front end of the handheld bracket, threaded grooves are opened through the front and rear ends of the hinge frame, hinge columns are fixedly connected to the left and right ends of the hinge frame, and two symmetrically distributed rotating parts are hinged on the hinge columns. The lower end of the rotating parts is fixedly connected to the upper end of the button cover, and a screen cover is fixedly connected to the front end of the button cover.
[0007] Preferably, the screw-mounted hinge frame can assist the integrated screen cover and button cover in rotating up and down to open and close. It can also be rotated and adjusted after rotation and opening to place the integrated screen cover and button cover in a suitable position when in use. When not in use, the integrated screen cover and button cover can protect the screen of the microcomputer and the buttons on the handheld stand.
[0008] Preferably, the upper end of the positioning device body is provided with a hand slot, and the rear end of the hand support is fixed with a handle. When in use, the hand slot and handle make it easier for the user to hold the positioning device body, thereby improving the user's comfort when holding it.
[0009] Preferably, a button body is installed on the handheld bracket. The button body is divided into function buttons and control buttons. During use, the button body allows the user to easily control or use the ultrasonic detector and the positioning device.
[0010] Preferably, the screen cover is adapted to the screen on the microcomputer, and the button cover is adapted to the button body. When in use, the screen cover adapted to the screen on the microcomputer and the button cover adapted to the button body can effectively prevent the user from accidentally touching the screen or button body of the microcomputer when not in use.
[0011] Preferably, the screw groove is adapted to the threaded post, and the outer wall of the handle is provided with anti-slip texture, which can prevent the user from slipping out of the hand during use.
[0012] Preferably, the hinge pins are fixed with four sets of protrusions that are equidistantly distributed around the hinge pins at their close ends, and four sets of grooves that are equidistantly distributed around the rotating parts at their far ends. In use, the protrusions and grooves can be used to position and fix the integrated screen cover and button cover after rotation adjustment.
[0013] Preferably, the protrusion and the groove are matched, and the nut is threadedly installed on the front outer wall of the threaded column. In use, the nut can limit the rotation of the rotating part that is threadedly installed on the threaded column.
[0014] The beneficial effects of this utility model are:
[0015] 1. When not in use, the integrated screen cover and button cover can protect the screen of the microcomputer and the buttons on the handheld stand, which can effectively improve their service life compared to the exposed button and screen structure.
[0016] 2. The screw-mounted hinge frame can assist the integrated screen cover and button cover in rotating up and down to open and close. It can also rotate and adjust the integrated screen cover and button cover after rotation and opening, so that the integrated screen cover and button cover can be placed in a suitable position during use. Compared with the existing cover protection structure, it can greatly improve the flexibility of the screen cover and button cover during use.
[0017] 3. The integrated screen cover and button cover can be positioned and fixed after rotation and adjustment by using protrusions and grooves. Compared with the existing cover structure, the screen cover and button cover can be limited and fixed after rotation and opening. Attached Figure Description

Detailed Implementation
[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] Please see Figures 1-7This utility model provides an embodiment: a rebar locator for bridge inspection, including a locator body 2, a screen cover 5, and a button cover 6. An ultrasonic detector 1 is fixedly connected to the lower end of the locator body 2, a microcomputer 3 is fixedly connected to the front end of the locator body 2, a handheld bracket 4 is fixedly connected to the upper end of the locator body 2, a threaded post 8 is fixedly connected to the front end of the handheld bracket 4, threaded grooves 15 are provided through the front and rear ends of a hinge frame 7, and hinge posts 14 are fixedly connected to the left and right ends of the hinge frame 7. Two symmetrically distributed rotating parts 12 are hingedly mounted on the hinge posts 14. The lower end of the rotating part 12 is fixed to the upper end of the button cover 6. The front end of the button cover 6 is fixed to the screen cover 5. The integrated screen cover 5 and button cover 6 can be rotated up and down to open and close by being threaded onto the threaded post 8 and the hinge frame 7. The integrated screen cover 5 and button cover 6 can also be rotated and adjusted after being rotated and opened, so that the integrated screen cover 5 and button cover 6 can be adjusted to a suitable position when in use. When not in use, the integrated screen cover 5 and button cover 6 can protect the screen on the microcomputer 3 and the buttons on the handheld bracket 4.
[0028] Please see Figures 3-5 In this embodiment, a handheld slot 11 is provided at the upper end of the positioning device body 2, and a handle 9 is fixedly connected to the rear end of the handheld bracket 4. When in use, the handheld slot 11 and handle 9 make it easy for the user to hold the positioning device body 2, thereby improving the user's comfort when holding it. A button body 10 is installed on the handheld bracket 4. The button body 10 is divided into function buttons and control buttons. When in use, the button body 10 makes it easy for the user to control or use the ultrasonic detector 1 and the positioning device body 2. The screen cover 5 is adapted to the screen on the microcomputer 3, and the button cover 6 is adapted to the button body 10. When in use, the screen cover 5 adapted to the screen on the microcomputer 3 and the button cover 6 adapted to the button body 10 can effectively prevent the user from accidentally touching the screen on the microcomputer 3 or the button body 10 when not in use.
[0029] Please see Figures 3-7 In this embodiment, the screw groove 15 is adapted to the threaded post 8, and the outer wall of the handle 9 is provided with anti-slip texture. During use, the anti-slip texture can prevent the user from slipping their hand.
