[0036] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0037] Example 1: See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , a horizontal bar with an anti-slip mechanism, comprising a horizontal bar body 1 and main support seats 2 arranged at both ends of the horizontal bar body 1 for clinging to a fixed surface, the main support seats 2 being used to cling to a fixed surface, and the fixed surface being a door, wall or other flat surface, is characterized in that an anti-loosening device 3 is arranged between the horizontal bar body 1 and the corresponding main support seat 2, and each main support seat 2 is provided with a detection mechanism 4 for detecting the tightness between the main support seat 2 and the fixed surface, when the detection mechanism 4 detects that the main support seat 2 and the fixed surface are loose, the detection mechanism 4 will be alarmed, so that the user can know it clearly and in time, and then the user can accurately and promptly adjust it through the anti-loosening device 3, thereby being more conducive to meeting the user's usage needs.

[0038] Example 2: It can be explained based on Example 1, as shown in Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10The anti-loosening device 3 includes an assembly groove 31 provided on the main support seat 2, a guide sleeve 32 is installed in the assembly groove 31, and an auxiliary support seat 33 is provided on the guide sleeve 32. The auxiliary support seat 33 is pressed against the main support seat 2, and the auxiliary support seat 33 is moved on the guide sleeve 32 to achieve the degree of pressing of the auxiliary support seat 33 against the main support seat 2, and further achieves the degree of pressing of the main support seat 2 against the fixed surface, which is conducive to the adjustment of loosening. An adjusting piece 34 for adjusting the tightness of the auxiliary support seat 33 is provided on the guide sleeve 32, and the horizontal bar body 1 can be inserted into the guide sleeve 32. When in use, it is only necessary to rotate the adjusting piece 34 clockwise or counterclockwise, so that the auxiliary support seat 33 can move back and forth on the guide sleeve 32, thereby making the auxiliary support seat 33 When the adjusting member 34 is rotated counterclockwise, the adjusting member 34 will force the auxiliary support seat 33 to move toward the side of the main support seat 2 on the guide sleeve 32, thereby causing the main support seat 2 to be more and more tightly pressed against the fixed surface, thereby achieving the effect of loosening or releasing. When the adjusting member 34 is rotated counterclockwise, the adjusting member 34 will force the auxiliary support seat 33 to move toward the side of the main support seat 2 on the guide sleeve 32, thereby causing the auxiliary support seat 33 and the main support seat 2 to be loose, thereby causing the main support seat 2 to be more and more loose against the fixed surface, which is conducive to the disassembly effect.

[0039] like Figure 6 、 Figure 7 and Figure 8 As shown, in order to prevent the guide sleeve 32 and the assembly groove 31 of the main support seat 2 from rotating relative to each other, the assembly groove 31 is provided with a limiting groove strip 11 extending along its length, and the guide sleeve 32 is provided with a limiting protrusion 321 that matches the limiting groove strip 11. Further, the outer surface of the guide sleeve 32 is provided with a smooth surface and an external threaded portion, and the smooth surface is provided with a limiting protrusion 321. The adjusting member 34 is provided with an internal thread. The internal thread and the external thread cooperate with each other to achieve back and forth movement of the adjusting member 34 on the external threaded portion, thereby promoting the tightness adjustment of the auxiliary support seat 33. Further, the adjusting member 34 includes a sleeve body, the inner wall of the sleeve body is provided with an internal thread, and the outer surface of the sleeve body is evenly spaced with protrusions. This arrangement facilitates the user to manually rotate clockwise or counterclockwise, making operation convenient.

[0040] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 9 and Figure 10As shown, the auxiliary support seat 33 includes a seat body 331, which is provided with a mounting hole 332 that is clearance-matched with the guide sleeve 32. The inner side wall of the mounting hole 332 is provided with a limit device groove 333 that cooperates with the limit protrusion 321. This is conducive to preventing the relative rotation of the auxiliary support seat 33 and the guide sleeve 32. The seat body 331 is provided with an "eight"-shaped foot 334. Correspondingly, the main support seat 2 is provided with a mounting groove for accommodating the "eight"-shaped foot 334. This arrangement is reasonable, simple in structure, and easy to implement. Further explanation: the seat body 331 and the "eight"-shaped foot 334 are integrally formed, which greatly improves the firmness of the structure.

[0041] Example 3: This can be explained based on Example 1 or Example 2, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the detection mechanism 4 includes a placement slot 41 arranged on the main support seat 2, and a circuit board 42 is installed in the placement slot 41. A transparent cover 43 for covering the circuit board 42 is provided on the placement slot 41, as well as an alarm light 44, a switch button 45 and a charging interface 46 arranged on the circuit board 42. The circuit board 42 is connected to a rechargeable battery 47 and a detection end 48. The detection end 48 can sense the tightness of one side of the main support seat 2 that is in contact with the fixed surface. After the switch button 45 is turned on, when looseness occurs, the detection end 48 will light up the alarm light 44 through the circuit board 42, so that the user can know it in time and accurately. When the alarm light 44 goes out, it means that it is normal. When the switch button 45 is turned off, it is in an inoperative state, which is beneficial to saving power. The transparent cover 43 is provided with a first through-hole and a second through-hole corresponding to the switch button 45 and the charging port 46. This facilitates manual opening and closing of the switch button 45 and charging. Furthermore, the detection terminal 48 utilizes a self-resetting switch (microswitch, micro-switch, or tactile switch). It is important to emphasize that the warning light 44 utilizes an LED, which is widely available and easy to implement. The circuit board 42 utilizes a PCB for ease of implementation.

[0042] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the main support seat 2 includes a main body 21 and a buffer layer 22 (with elasticity) on the side opposite to the fixed surface of the main body 21. The main body 21 and the buffer layer 22 are locked by a number of fixing parts. A detection end 48 is installed on the main body 21 on the side opposite to the buffer layer 22. The buffer layer 22 is provided with a recess 23 that cooperates with the detection end 48. Since the buffer layer 22 is elastic, when the buffer layer 22 can be tightly squeezed on the fixed surface to cause the detection end 48 to be pressed, the detection end 48 will pass the circuit board 42 signal, and the circuit board 42 will determine that it is in a tight state. The circuit board 42 will not light up the alarm light 44, but will turn off the signal. When there is a gap between the fixed surface and the buffer layer 22, looseness occurs. At this time, the buffer layer 22 has elasticity and returns to its original state. The buffer layer 22 will not activate the detection end 48. The detection end 48 will send a signal to the circuit board 42. The circuit board 42 will determine that the looseness is not tight enough, and the circuit board 42 will notify the alarm light 44 to light up the alarm, which is more convenient for users to use. It is further explained that the fixing parts are bolts or screws, which are easy to disassemble and install.
