Description

Technical Field

[0001] This utility model relates to the field of speed switches, and more specifically, to a device for preventing speed switches from being damaged by impact. Background Technology

[0002] A speed switch is a key sensor device that can monitor and control the speed of mechanical equipment or moving objects in real time. When the speed is detected to exceed or fall below the preset safety range, it will quickly and automatically cut off or adjust the power source, thereby effectively preventing safety accidents or equipment damage caused by abnormal speed.

[0003] The existing speed switches still have the following problems when in use:

[0004] (1) In the prior art, when installing the speed switch, the speed switch is usually directly fixed on the base bracket of the tail wheel. When the tail wheel is misaligned, the speed switch is easily damaged, causing the equipment to malfunction.

[0005] (2) After the speed switch is installed on the base bracket of the tail wheel, it is inconvenient to adjust the installation position. Since different equipment or application scenarios have specific requirements for the monitoring position and angle of the speed switch, if the switch position is inaccurate, it will be unable to accurately capture the key speed change information, thus affecting its monitoring effect.

[0006] (3) When the existing speed switch is installed, it is usually fixed on one side of the rotating shaft by bolts. When it needs to be repaired or replaced, the process of disassembly and reinstallation becomes extremely cumbersome.

[0007] Therefore, we have made improvements to this by proposing a device to prevent the speed switch from being damaged. Utility Model Content

[0008] In view of the shortcomings of the prior art, this utility model provides a device to prevent the speed switch from being damaged by impact, thus solving the problems mentioned in the background art.

[0009] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0010] A device to prevent the speed switch from being damaged is provided to solve the above problem.

[0011] The application is as follows:

[0012] The device includes a rotating shaft, characterized in that: a bearing is fixedly installed on the outside of one end of the rotating shaft, and a fixing frame is fixedly installed on the upper surface of the bearing, and the fixing frame is L-shaped; a connecting rod is provided on one side of the fixing frame, and a speed switch body is provided on the lower side of the connecting rod; a sensing plate is fixedly installed on one end surface of the bearing; an adjustment mechanism is provided between the fixing frame and the connecting rod, and a fixing mechanism is provided between the connecting rod and the speed switch body;

[0013] The adjustment mechanism includes a slide groove and a sliding rod. The slide groove is formed on one side surface of the fixed frame. The sliding rod is slidably connected in the slide groove, and the other end of the sliding rod is fixedly connected to the connecting rod. A threaded rod is rotatably connected inside the slide groove, and the threaded rod and the sliding rod are connected by a threaded connection.

[0014] The fixing mechanism includes a first fixing half-ring and a second fixing half-ring, and the first fixing half-ring and the second fixing half-ring are rotatably connected. The first fixing half-ring is fixedly installed at the lower end of the connecting rod, and the first fixing half-ring and the second fixing half-ring are engaged with the speed switch body.

[0015] As a preferred technical solution of this application, a knob is fixedly installed at one end of the threaded rod, and the knob is located on one side of the fixing frame.

[0016] As a preferred technical solution of this application, two baffles are fixedly installed on the outside of the speed switch body, and the first fixed half ring and the second fixed half ring are disposed between the two baffles.

[0017] As a preferred technical solution of this application, an installation groove is provided on the lower surface of one side of the first fixed half ring, and an installation block is fixedly installed on the upper surface of one side of the second fixed half ring, wherein the installation block is snapped into the installation groove.

[0018] As a preferred technical solution of this application, a groove is provided on one side surface of the mounting block, and a baffle is slidably connected inside the groove. A locking block is fixedly installed on one side surface of the baffle, and a locking groove is provided on one side surface of the mounting groove, and the locking block is engaged with the locking groove.

[0019] As a preferred technical solution of this application, a spring is fixedly installed between one side surface of the baffle and the inner wall of the slot, and the upper surface of the card block is arc-shaped.

[0020] As a preferred technical solution of this application, arc-shaped rubber pads are fixedly installed on the inner walls of both the first and second fixed half-rings.

[0021] As a preferred technical solution of this application, a fixing rod is fixedly installed on the outer surface of the fixing frame.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] In the scheme of this application:

[0024] 1. By designing structures such as bearings, fixing frames, and connecting rods, the sensing distance between the speed switch and the rotating shaft is controlled within a fixed distance. This prevents the speed switch from being damaged during shaft movement, thus preventing the equipment from tripping erroneously. Even if the tail wheel moves off-center, it will not directly contact the speed switch body, thereby greatly reducing the risk of equipment malfunction and speed switch damage caused by impact.

[0025] 2. By using the adjustment mechanism, rotating the threaded rod can drive the sliding rod to move within the groove, thereby achieving precise adjustment of the position of the speed switch body. This meets the specific requirements of different equipment or application scenarios for the monitoring position and angle of the speed switch, ensuring that the speed switch can accurately capture key speed change information and improve the monitoring effect.

[0026] 3. The installation mechanism, employing a first fixed half-ring and a second fixed half-ring, along with their interlocking connection, greatly simplifies the disassembly and installation process of the speed switch. It eliminates the need for complex tools or time-consuming disassembly and reinstallation of bolts; simply separating or merging the first and second fixed half-rings allows for easy replacement or repair of the speed switch. This not only improves maintenance efficiency but also reduces maintenance costs, significantly minimizing equipment downtime. Attached Figure Description
