[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] The following describes some embodiments of the utility model in conjunction with the accompanying drawings to provide a desk height detection device.

[0028] Embodiment 1:

[0029] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a desk height detection device, including a base 100, a lower support rod 200, an upper support rod 300, a latch 400, a locking assembly 500, a sliding member 600 and an ultrasonic detection assembly 700.

[0030] Specifically, the lower support rod 200 is arranged on the top of the base 100, and the lower support rod 200 is used to support the upper support rod 300 and the ultrasonic detection assembly 700 for detection.

[0031] Specifically, the upper support rod 300 is hingedly connected to the top of the lower support rod 200. The hinge connection allows the lower support rod 200 and the upper support rod 300 to be folded for transportation. A sliding groove 301 for sliding the sliding member 600 is provided on the right side of the upper support rod 300. The sliding groove 301 allows the sliding member 600 to slide on the upper support rod 300 so as to fix the locking assembly 500. A display screen for displaying height data is provided on the right side of the upper support rod 300.

[0032] It should be noted that the connection between the upper support rod 300 and the lower support rod 200 is provided with a round hole for inserting the pin 400. The pin 400 can be inserted into the round hole to play a binding effect so as to fix the upper support rod 300 and the lower support rod 200.

[0033] Specifically, the latch 400 is inserted into the lower support rod 200 and the upper support rod 300, the latch 400 is T-shaped, and the bottom edge of the latch 400 is rounded, which facilitates the insertion of the latch 400 into the upper support rod 300 and the lower support rod 200, and plays a guiding role.

[0034] Specifically, the locking assembly 500 includes a shielding box 501 arranged on the right side of the lower support rod 200, a shielding frame 502 arranged on the right side of the upper support rod 300, a top cover 503 hingedly connected to the shielding frame 502, a first fixing ring 504 arranged at the bottom of the top cover 503 and an iron lock 505 inserted into the first fixing ring 504. The top cover 503 can be rotated to cover the top of the shielding frame 502. After covering, the iron lock 505 can be used to lock the first fixing ring 504 and the sliding member 600. After locking, due to the restraint of the sliding member 600, the rotation angle of the top cover 503 is limited, and a child cannot put his hand into the shielding frame 502 to move the latch 400. At the same time, due to the obstruction of the top cover 503, the latch 400 cannot be separated from the upper support rod 300 and the lower support rod 200, thereby preventing a child from accidentally touching the latch 400 and causing the support rod to fold and injuring the body.

[0035] Specifically, the sliding member 600 includes a sliding block 601 slidably connected to the lower support rod 200 and a second fixing ring 602 arranged on the right side of the sliding block 601. The sliding member 600 can slide upward to prevent the sliding member 600 from obstructing the top cover 503 from covering the shielding frame 502. At the same time, the second fixing ring 602 can be fixed to the first fixing ring 504 by an iron lock 505 for use.

[0036] Specifically, the ultrasonic detection component 700 is arranged on the upper support rod 300, and the ultrasonic detection component 700 includes a sliding seat 701 inserted into the upper support rod 300, a fixed plate 702 arranged on the right side of the sliding seat 701, an ultrasonic transducer 704 arranged at the bottom of the fixed plate 702, and an adjustment knob 703 threadedly connected to the left side of the sliding seat 701. The adjustment knob 703 can be loosened. After loosening, the height of the ultrasonic transducer 704 can be moved and adjusted for use. At the same time, the ultrasonic detection component 700 can be moved away from the upper support rod 300 for disassembly.

[0037] Embodiment 2:

[0038] Reference Figure 1, which is the second embodiment of the utility model, which is different from the first embodiment in that it also includes a manual detection component 800, the manual detection component 800 includes a vertical rod 801 set on the top of the base 100, a scale line 802 set on the right side of the vertical rod 801 and a moving rod 803 inserted at the top of the vertical rod 801, the moving rod 803 can move along the direction of the vertical rod 801 until the moving rod 803 abuts against the top of the desk, and after abutting, the scale line 802 where the moving rod 803 is located can be checked to manually detect the height for calibration.

[0039] The working principle and use process of the utility model are as follows: when in use, the user can rotate the upper support rod 300 to the top of the lower support rod 200, and after the rotation, the latch 400 can be inserted into the round holes on the upper support rod 300 and the lower support rod 200 in sequence, and after the insertion, the sliding member 600 is first moved upward through the slide groove 301 until it moves to the highest point, and then the top cover 503 is rotated to cover the top of the shielding frame 502, and then the sliding member 600 is moved downward to approach the first fixing ring 504, and after approaching, the iron lock 505 can be used to lock the first fixing ring 504 and the second fixing ring 602 of the sliding member 600 After locking, due to the restraint of the sliding member 600, the rotation angle of the top cover 503 is limited, and the child cannot put his hand into the shielding frame 502 to move the latch 400. At the same time, due to the obstruction of the top cover 503, the latch 400 cannot be separated from the upper support rod 300 and the lower support rod 200, thereby preventing the child from accidentally touching the latch 400 and causing the support rod to fold and injure the body. After that, the moving rod 803 of the manual detection component 800 can be moved until the moving rod 803 abuts against the top of the desk. After abutment, check the scale line 802 where the moving rod 803 is located, and manually detect the height for calibration.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
