[0026] As Figures 1-4 shown, a new type of elevator control cabinet convenient for instrument detection includes a control cabinet housing 1. A box door 3 is hinged to the front end of the control cabinet housing 1. A support plate 5 is provided at the front end of the control cabinet housing 1. A rectangular groove 10 is opened in the upper part of the front end of the support plate 5. A support member 7 is connected to the middle of the front end of the support plate 5. A tooth column 6 is rotatably connected to the rear inner wall of the rectangular groove 10. The tooth column 6 is rotatably connected in the rectangular groove 10 through a rotating shaft. A clamping member 8 is meshed and connected to the rear part of the outer surface of the tooth column 6. The clamping member 8 is connected to the rectangular groove 10. The support member 7 moves downward under the action of gravity, and drives the clamping member 8 through the tooth column 6 to clamp both sides of the detector. When in use, the control cabinet housing 1 is connected to the elevator circuit. When maintenance is required, the box door 3 is opened, and a measuring instrument (such as a multimeter) is used to detect the electrical components 2 in the control cabinet housing 1. When in use, the worker needs to hold the measuring instrument with one hand and use the measuring pen for detection. Usually, there are two measuring pens. When the detection range has a large span, the worker needs to hold the detector and the detection pen with one hand for detection, which brings difficulties to the worker's detection.

[0027] To improve the above situation, first, a support member 7 is provided to support the bottom of the tester. The support member 7 includes an L-shaped plate 71. The L-shaped plate 71 is slidably connected to the front end of the support plate 5. The L-shaped plate 71 is slidably connected to the support plate 5 through a guide rail and a chute. A plurality of springs 74 are installed at the lower end of the L-shaped plate 71. The springs 74 are used to drive the L-shaped plate 71 to reset. A connecting plate 75 is commonly installed at the lower ends of the plurality of springs 74. The connecting plate 75 is fixedly connected to the support plate 5. A through groove 72 is formed at the front end of the L-shaped plate 71. A first rack 73 is installed on the right inner wall of the through groove 72. The tooth column 6 extends into the through groove 72. The front part of the outer surface of the tooth column 6 is meshed with the first rack 73. Since the tooth column 6 is meshed with the first rack 73, and driven by the tooth column 6, the two sides of the measuring instrument are fixed by the clamping member 8. The clamping member 8 includes second racks 81. There are two second racks 81. Both of the two second racks 81 are slidably connected to the rear wall of the rectangular groove 10 through a guide rail and a chute. Both of the two second racks 81 are meshed with the rear part of the outer surface of the tooth column 6. The two second racks 81 are rotationally symmetrically distributed at 180 degrees with the tooth column 6 as the center. Movable connections are provided at the mutually remote ends of the two second racks 81 with clamping plates 82. The second racks 81 and the clamping plates 82 are both L-shaped structures. When in use, the tester is placed above the L-shaped plate 71. Affected by gravity, the L-shaped plate 71 moves downward. The springs 74 are compressed. The L-shaped plate 71 drives the tooth column 6 to rotate through the first rack 73. The rear part of the outer surface of the tooth column 6 drives the two second racks 81 to approach each other. The two second racks 81 respectively drive the two clamping plates 82 to approach each other. The two clamping plates 82 fix the two sides of the tester. The L-shaped plate 71 stops moving downward. The operation is simple and the fixation is convenient. The maintenance personnel do not need to hold the detector by hand, which facilitates freeing both hands for other necessary operations, reduces the maintenance difficulty, and brings convenience to the workers.

[0028] When the detector cannot be placed between the two clamping plates 82, first, lead screws 821 are threadedly sleeved inside both of the two clamping plates 82. In order to enable the lateral stable movement of the clamping plates 82, guide rods 822 are movably sleeved inside both of the two clamping plates 82. The two guide rods 822 are respectively fixedly connected to the two second racks 81. The two lead screws 821 are respectively movably connected to the two second racks 81. The lead screws 821 are movably connected to the second racks 81 through bearings. When in use, the two lead screws 821 are respectively rotated to drive the clamping plates 82 to move outward, so that the distance between the clamping plates 82 becomes larger, and then the detector can be placed between the two clamping plates 82, which facilitates the fixation of detectors of different sizes and improves the applicable range of the components.

[0029] To prevent the second rack 81 from disengaging from the rectangular groove 10, a first stopper 811 is installed at the upper end of the upper second rack 81, and a second stopper 101 is provided on the left side of the first stopper 811. The second stopper 101 is installed on the upper inner wall of the rectangular groove 10. The movement range of the second rack 81 can be restricted by the second stopper 101 and the first stopper 811.

[0030] Furthermore, when workers need to inspect the electrical components 2 above, loosen the screw rod 9 to drive the support plate 5 to move up and down, and the fixed position of the detector can be adjusted, which is convenient for workers to inspect other positions and brings convenience to workers. The specific structure is as follows: A slide rail 4 is movably sleeved inside the support plate 5. The slide rail 4 is of a T-shaped structure and is fixedly connected to the door 3. A screw rod 9 is provided at the lower part of the front end of the support plate 5. The screw rod 9 is threaded through the support plate 5 and is movably connected to the front end of the slide rail 4. The position of the support plate 5 can be fixed by the screw rod 9 pressing against the slide rail 4.

[0031] In order to connect with the elevator circuit, electrical components 2 are arranged in the control cabinet housing 1 through clamping strips.
