[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3This embodiment discloses a portable building engineering quality testing instrument, comprising a housing 1, inside which is a storage and testing component for safekeeping and protection during testing. The storage and testing component includes a lead screw 2 rotatably connected to the inner side of the housing 1, a driven bevel gear 3 fixedly connected to the outer side of the lead screw 2, a drive shaft 4 rotatably connected to the right side of the housing 1, a knob 5 fixedly connected to the rear end of the drive shaft 4, a driving bevel gear 6 fixedly connected to the front end of the drive shaft 4, a storage plate 7 threadedly connected to the outer surface of the lead screw 2, a limit rod 8 and a partition 17 fixedly connected to the inner side of the housing 1, a quality testing device 9 fixedly mounted on the top of the storage plate 7, a testing rod 10 fixedly connected to the top of the quality testing device 9, and a portability component on the outer side of the housing 1. When the operator rotates the drive shaft 4 clockwise using the knob 5, the driving bevel gear 6 drives the lead screw 2 to rotate counterclockwise continuously via the driven bevel gear 3, thereby causing the storage plate 7 to move vertically upwards, and thus gradually extending the testing rod 10 of the quality testing device 9 outside the housing 1 for testing.

[0025] During the process, once the test is completed, the staff only needs to rotate the drive shaft 4 counterclockwise using the knob 5 to move the storage plate 7 vertically downwards, thereby retracting the detection rod 10 of the quality detection device 9 into the housing 1 for storage and protection. Ultimately, this reduces the probability of dust, oil, or foreign matter contamination, ensuring the accuracy of the test data. At the same time, it reduces the probability of damage to precision components, thus improving the service life.

[0026] In this embodiment, the portable component includes a fixing frame 11 fixedly connected to the left and right sides of the housing 1. A rotating shaft 12 is rotatably connected to the inner side of the fixing frame 11. An elastic cord 13 is sleeved on the outer surface of the fixing frame 11. Velcro 14 is attached to both the front and back of the elastic cord 13. The fixing frame 11 and the rotating shaft 12 can set the two elastic cords 13 to the left and right sides of the housing 1, so that the staff can wrap the two elastic cords 13 around their hands or legs and fix them with Velcro 14, thereby fixing the utility model to the hands or legs, so that it does not need to be held and is convenient for outdoor use.

[0027] It should be noted that the top of the housing 1 has an outlet 15, and a plug 16 is snapped into the inside of the outlet 15. The plug 16 can seal the outlet 15 when it is not in use, so as to prevent dust and debris from entering the interior of the housing 1.

[0028] Specifically, the plug 16 is made of rubber, and a groove is provided on the top of the plug 16.

[0029] It should be noted that the storage plate 7 is slidably connected to the limiting rod 8, and both the lead screw 2 and the limiting rod 8 pass through the partition 17. The partition 17 serves to separate the structures and prevent them from affecting each other.

[0030] Specifically, the driven bevel gear 3 meshes with the driving bevel gear 6 for transmission, and a ball bearing sleeve for rotating the drive shaft 4 is fixedly installed on the right side of the housing 1.

[0031] It should be noted that the housing 1 is made of plastic, and the outer surface of the knob 5 has anti-slip grooves.

[0032] Specifically, a cover 18 is fixedly installed on the outer surface of the housing 1. The outer surface of the cover 18 is provided with a display screen and control buttons. The display screen and control buttons on the outside of the cover 18 enable the staff to control the quality detection device 9 and the detection rod 10, and display the detected data.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the operator rotates the drive shaft 4 clockwise using knob 5, causing the active bevel gear 6 to drive the lead screw 2 to rotate counterclockwise via the driven bevel gear 3. This causes the storage plate 7 to move vertically upward, gradually extending the detection rod 10 of the quality detection device 9 outside the housing 1 for detection. After the detection is completed, the operator simply rotates the drive shaft 4 counterclockwise using knob 5 to move the storage plate 7 vertically downward, retracting the detection rod 10 of the quality detection device 9 back into the housing 1 for safe storage. Additionally, the two elastic straps 13 are wrapped around the hand or leg and secured with Velcro 14, thus fixing the device to the hand or leg, eliminating the need for gripping and facilitating outdoor use.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
