Description

Technical Field

[0001] This utility model relates to the field of contactor technology, specifically to a silent contactor for elevators. Background Technology

[0002] In the field of existing elevator contactor technology, traditional contactors are mostly connected to the guide rail using a single slot or bolt fixing structure. Relying solely on a single-sided slot to engage with the guide rail, the slot is prone to loosening or even detaching from the guide rail during frequent elevator starts and stops and operational vibrations, severely affecting the contactor's reliability and service life. Furthermore, some contactors using bolt fixing require tools to tighten each bolt individually during installation, which is cumbersome and time-consuming, impacting work efficiency.

[0003] Based on the above, this utility model proposes a silent contactor for elevators, which can effectively solve the above problems. Utility Model Content

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0020] A silent contactor for elevators includes a contactor body 1. A first connecting portion 2 and a second connecting portion 3 are respectively provided on both sides of the bottom of the contactor body 1. A mounting groove 5, which mates with a guide rail 4, is provided between the first connecting portion 2 and the second connecting portion 3. A first locking groove 21, which engages with the guide rail 4, is provided on the inner side of the first connecting portion 2. A sliding groove 6 is provided in the middle of the second connecting portion 3, and a sliding component is slidably connected inside the sliding groove 6. Bosses 7 are respectively provided on both sides of the mounting groove 5 of the first connecting portion 2, and each boss 7 is provided with a clamping mechanism that abuts against the guide rail 4.

[0021] This utility model forms an installation groove 5 that mates with the guide rail 4 by setting a first connecting part 2 and a second connecting part 3 at the bottom of the contactor body 1. Under the mutual cooperation of the first slot 21 of the first connecting part 2 and the sliding component, the contactor body 1 and the guide rail 4 are snapped together. At the same time, the pressing mechanism on the protrusions 7 on both sides of the installation groove 5 abuts against the guide rail 4, thereby significantly improving the stability and convenience of installation.

[0022] Furthermore, in another embodiment, the sliding assembly includes a slider 8, the bottom front side of which has a second slot 81 for engaging with the guide rail 4, the rear of which has a pull groove 82, and the middle of which has a spring groove 83, with a first spring 9 installed inside the spring groove 83.

[0023] By setting up a sliding component, the second slot 81 of the slider 8 of the sliding component can be engaged with the guide rail 4, improving the reliability of the connection; the pull groove 82 at the rear facilitates manual pulling of the slider 8 for sliding operation; the spring groove 83 in the middle, in conjunction with the first spring 9, allows the slider 8 to automatically reset after sliding by means of the spring force, ensuring that the slot and the guide rail always remain engaged, enhancing the stability of the connection.

[0024] Furthermore, in another embodiment, a spring seat 61 corresponding to the position of the spring groove 83 is fixedly connected to the upper surface of the slide groove 6, one end of the first spring 9 abuts against the spring seat 61, and the other end of the first spring 9 abuts against the side wall of the spring groove 83.

[0025] The spring seat 61 abuts against the first spring 9 in the spring groove 83, providing a fixed support point for the first spring 9. This allows the spring force to act more stably on the slider 8, ensuring that the slider 8 is subjected to uniform force during sliding. This, in turn, ensures the locking effect between the slider 8 and the guide rail 4, further enhancing the stability of the contactor installation.

[0026] Furthermore, in another embodiment, lower protrusions 84 are fixedly connected to the front parts of both sides of the slider 8, and upper protrusions 85 are fixedly connected to the middle parts of both sides of the slider 8. Lower grooves 62 that cooperate with the lower protrusions 84 and upper grooves 63 that cooperate with the upper protrusions 85 are respectively opened on both sides of the slide groove 6.

[0027] By having the lower protrusions 84 on both sides of the slider 8 cooperate with the lower grooves 62 on both sides of the slide groove 6, and the upper protrusion 85 in the middle cooperate with the upper groove 63, the sliding trajectory of the slider 8 can be limited, preventing the slider 8 from deviating or falling off the slide groove 6 during the sliding process. At the same time, it enhances the tightness of the connection between the slider 8 and the slide groove 6, making the sliding of the slider 8 more stable and reliable.

[0028] Furthermore, in another embodiment, the clamping mechanism includes a cavity 71 formed within the boss 7, a connecting post 10 disposed within the cavity 71, the top of the connecting post 10 penetrating through the top of the cavity 71 and fixedly connected to a pressure plate 11, a movable plate 12 fixedly connected to the bottom of the connecting post 10, the bottom of the movable plate 12 fixedly connected to the top of a second spring 13, and the bottom of the second spring 13 fixedly connected to the bottom of the cavity 71.

[0029] By setting a clamping mechanism, the pressure plate 11 at the top of the connecting column 10 of the clamping mechanism can directly abut against the guide rail 4. The spring force of the second spring 13 keeps the pressure plate 11 pressing against the guide rail 4, thereby increasing the installation strength between the contactor body 1 and the guide rail 4 and preventing loosening.

[0030] The working principle of one embodiment of this utility model is as follows:

[0031] First, align the mounting groove 5 at the bottom of the contactor body 1 with the guide rail 4. Then, insert the first slot 21 of the first connecting part 2 into the corresponding protrusion of the guide rail 4 to complete the initial positioning. Next, manually pull the pull groove 82 at the rear of the slider 8 to make the slider 8 slide backward along the slide groove 6. At this time, the first spring 9 in the spring groove 83 is compressed between the spring seat 61 and the side wall of the spring groove 83, storing elastic potential energy. When the slider 8 slides to the position where the second slot 81 is aligned with the guide rail 4, release the pull groove 82. The elastic restoring force of the first spring 9 pushes the slider 8 forward, so that the second slot 81 is engaged with the corresponding part of the guide rail 4, forming a double-locking structure. Then, the pressing mechanism in the protrusions 7 on both sides of the mounting groove 5 works synchronously. The second spring 13 pushes the moving plate 12 and the connecting column 10 to move upward, so that the pressure plate 11 tightly abuts against the surface of the guide rail 4. The elastic pre-tightening force further enhances the stability of the overall connection.
