In this embodiment, the angle adjustment bracket 2 can be adjusted manually. The servo motor 3 is fixedly mounted on the angle adjustment bracket 2. The upper end of the rotating shaft 4 is drivingly connected to the servo motor 3, and the lower end is fixedly connected to the clamp 5, 5' or 5". The clamp is used to clamp the knob or handle of the sanitary product to be tested. Therefore, when the servo motor 3 rotates, it drives the knob or handle of the sanitary product to be tested to rotate through the clamp, completing the corresponding test items.

[0024] In the shown embodiment, the mounting bracket 1 may include a vertical profile 11, upper and lower bearing mounting seats 12, upper and lower bearings 13, an intermediate sliding seat 14, a lead screw 15, a nut 16, and a handwheel 17. Among them, the vertical profile 11 is an aluminum profile and has two vertically extending mounting grooves 111. The upper and lower bearing mounting seats 12 and the intermediate sliding seat 14 are slidably mounted on the vertical profile 11 by cooperating with the mounting grooves through quick bolts (not shown). When it is necessary to adjust the mounting position of the mounting bracket 1, loosen the quick bolts, move the upper and lower bearing seats 12 to the required position, and then tighten the quick bolts. The upper and lower bearings 13 are respectively mounted on the upper and lower bearing mounting seats 12. The lead screw 15 is fixedly inserted through the upper and lower bearings 13. The nut 16 is fixed (for example, welded) on the intermediate sliding seat 14 and is threadedly connected to the lead screw 15. The handwheel 17 is fixed to the end (specifically, the lower end) of the lead screw 15. The intermediate sliding seat 14 can slide up and down along the vertical profile 11. The angle adjustment bracket 2 is fixedly mounted (for example, welded) on the intermediate sliding seat 14. Therefore, when it is necessary to adjust the height, loosen the quick bolts on the intermediate sliding seat 14, then rotate the handwheel 17 to move the clamp to the required height, and finally tighten the quick bolts.

[0025] The angle adjustment bracket 2 may include a base 21, a manual angle adjuster 22, and a motor mount 23. The base 21 is fixed on the middle sliding seat 14. Specifically, the base 21 is generally U-shaped and includes a back plate 211 and upper and lower cross plates 212. Among them, the back plate 211 is welded to the middle sliding seat 14 and is provided with a plurality of circular hollow holes 213 to reduce weight and save material costs. The upper and lower cross plates 212 are respectively provided with one and two strip holes 214 extending along the length, so that the manual angle adjuster 22 can be fixedly installed on the base 21 in a position-adjustable manner. That is, the manual angle adjuster 22 is fixed on the base 21 by the cooperation of a quick bolt and the strip hole 214. The manual angle adjuster 22 has a worm 221 and a rotating member (rotating shaft) 222 that are orthogonal to each other. A handwheel is fixed to the end of the worm 221 for convenient operation. A gear meshing with the worm 221 is provided on the rotating shaft 222, so that the rotating shaft 222 rotates by rotating the handwheel. The motor mount 23 is L-shaped in reverse and includes an upper cross plate and a vertical plate. The servo motor 3 is fixed on the upper cross plate. An installation hole 231 and a pair of radially symmetric arc-shaped slots 232 are provided on the vertical plate. The installation hole 231 and the rotating shaft 222 are fixed together by keyway cooperation. The vertical plate is fixed on the manual angle adjuster 22 by the cooperation of a quick bolt (not shown) and the arc-shaped slot 232. That is, the motor mount 23 is rotatably installed on the manual angle adjuster 22.

[0026] Preferably, a torque sensor 6 is installed between the servo motor 3 and the rotating shaft 4. The torque sensor 6 is used to measure the torque when the clamps 5, 5', 5" actuate the knob or handle of the sanitary product, which is convenient for subsequent analysis. At the same time, the torque sensor 6 can also be used as a protection signal for the servo motor 3. When the torque detected by the torque sensor 6 exceeds the threshold, the servo motor 3 stops to avoid damage to the servo motor 3.

[0027] In addition, the servo motor 3 is equipped with a reducer 31. The reducer 31 is connected to the upper end of the torque sensor 6 through a first coupling 71. The lower end of the torque sensor 6 is drivingly connected to the rotating shaft 4 through a second coupling 72. Preferably, the rotating shaft 4 is telescopically installed on a sleeve 8. The sleeve 8 is connected to the lower end of the torque sensor 6 through a second coupling 72. Specifically, an axially extending groove 41 is provided on the side wall of the rotating shaft 4. Two fixing holes 81 are provided on the sleeve 8. The rotating shaft 4 is inserted into the sleeve 8 and fixed by screws passing through the fixing holes and tightened with the groove 41. Preferably, the lower end of the rotating shaft 4 is a polyhedron to facilitate fixation with a setscrew.

[0028] As Figure 3As shown, the fixture 5 is a screw-type fixture, applicable to knobs with three or six faces. The fixture 5 includes a mounting bracket 51 and three clamping rods 52. The mounting bracket 51 has three arm portions 511, and each arm portion 511 is provided with a slot 5111 extending along the length direction. The three clamping rods 52 are respectively fixed to the arm portion 511 in a position-adjustable manner by cooperating with the slot 5111 through a quick bolt (not shown). That is, according to the different sizes of the knob, the distance between the three clamping rods 52 is adjusted so that the clamping rods 52 clamp the knob. The mounting bracket 51 has a central through hole 512 and a radial screw hole 513 communicating with the central through hole 512. The lower end of the rotating shaft 4 is inserted into the central through hole 512 and fixed by screwing a setscrew (not shown) into the radial screw hole 513. Preferably, a protective sleeve 53 is sleeved on the clamping rod 52 to prevent damage to the appearance of the knob. The protective sleeve 53 can be made of rubber or silica gel, etc.

[0029] As Figure 4 shown, the fixture 5' is similar in structure to the fixture 5 and is also a screw-type fixture, which is applicable to knobs with four or eight faces. The difference from the fixture 5 is only the number of the arm portions 511' and the clamping rods 52' of the mounting bracket 51'. In this embodiment, the number of both the arm portions 511' and the clamping rods 52' is 4.

[0030] As Figure 5 shown, the fixture 5" is a swing-type fixture, applicable to a handle that can be switched on and off by swinging left and right. The fixture 5" includes a swing arm 51", a mounting block 52" and a pair of clamping blocks 53". One end of the swing arm 51" is provided with a through hole 512" and a radial screw hole 513" communicating with the through hole 512". The lower end of the rotating shaft 4 is inserted into the central through hole 512" and fixed by screwing a setscrew (not shown) into the radial screw hole 513". The swing arm 51" is provided with a slot 511" extending along the length direction, so that the other end of the swing arm 51" can be fixed to the mounting block 52" in a position-adjustable manner by the cooperation of a quick bolt and the slot 511". The mounting block 52" is provided with left and right slots 521" spaced apart, and the upper ends of a pair of clamping blocks 53" are fixed to the mounting block 52" in a position-adjustable manner by the cooperation of a quick bolt (not shown) and the slots 521". That is, the distance between a pair of clamping blocks 53" can be adjusted to adapt to handles of different sizes.

[0031] Preferably, the quick bolt is equipped with a butterfly knob for convenient operation.

[0032] The working process of the present rotation mechanism will be briefly described below. First, according to the specifications of the knob or handle of the sanitary ware product to be tested, the corresponding fixture 5, 5' or 5" is selected, and then the fixture is fixed to the rotating shaft 4. Then, by operating the handwheel 17, the fixture is placed at an appropriate height position, and then the angle and the front-back, left-right positions of the fixture are adjusted according to actual needs, so that the fixture can firmly clamp the knob or handle. Finally, the test program is started. It can be seen that the present rotation mechanism can select a suitable fixture according to the specifications of the sanitary ware product to be tested and adjust the corresponding installation position, which is very flexible and has high versatility.
