Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor hook frame technology, specifically a low-noise motor hook frame. Background Technology
[0002] Brushless motors use semiconductor switching devices to achieve electronic steering, replacing the contact commutator and brushes of traditional brushed motors. Therefore, the wiring connection between the electronic switching devices and the brushless motor stator must be secure and reliable. Current technology involves directly aligning the wires of both the brushless motor stator and the electronic switching devices before soldering. This easily leads to inaccurate wire placement, loose wires, poor wire quality, and other defects, affecting the overall performance and aesthetic design of the brushless motor. Therefore, a suitable wire guide is necessary.
[0003] For example, Chinese utility model patent CN218576089U discloses a fixing device for assembling a motor hook frame, including a fixing frame with a cylindrical structure. Anti-slip pads are fixedly connected to the two side walls of the fixing frame, and support columns are set on both sides of the anti-slip pads. A slot is set on the opposite side of the support column. The support column has a top opening, and the slot has a T-shaped structure. A fixing component is fixedly connected to the top of the support column. The fixing component can be moved to cover the top opening of the support column. When the hook frame needs to be disassembled, the pull handle drives the pull rod to extend outward of the support box. At this time, the slide plate slides in the slide groove. The slide plate moves the baffle box support cylinder until the slot is fully exposed. Pulling the hook frame directly removes it from the slot. Releasing the pull handle, under the rebound force of the spring, pushes the slide plate to move the baffle outward of the support cylinder until the side wall of the baffle abuts against the anti-collision pad. It is convenient and quick. In addition, a buffer pad is set to protect the hook frame and improve its service life.
[0004] However, existing motor hook frames have multiple hooks fixedly connected to the hook frame, and if the hooks are damaged during use, they are not easy to disassemble and replace.
[0005] Therefore, we propose a low-noise motor hook bracket to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a low-noise motor hook bracket to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-noise motor hook frame, including a fixed frame, a hook frame, and a hook head. Multiple mounting blocks are fixedly installed on the outer surface of the fixed frame. An installation groove is opened on one side of each mounting block. There are two hook frames. Connecting blocks are fixedly connected to both sides of the two hook frames. The connecting blocks contact the installation groove. The connecting blocks and the mounting blocks are connected by fastening bolts.
[0008] The hook frame has multiple positioning slots on one side, and there are multiple hook heads. Positioning blocks are fixedly installed on one side of each hook head. The bottom surface of the positioning block has a locking hole, and the positioning block locks into the positioning slot. The hook frame has multiple built-in slots. One end of a spring is fixedly connected to both ends of the bottom surface of each built-in slot, and the other end of the spring is fixedly connected to a slider. The slider is slidably connected to the built-in slot. A locking rod is fixedly connected to the top surface of the slider, and the locking rod locks into a locking hole. A pressing frame is fixedly connected to the top surface of the slider.
[0009] The spring includes a first fitting ring, a first fitting spring fixedly connected to the outer wall of the first fitting ring, a main support spring fixedly connected to the end of the first fitting spring, a second fitting spring fixedly connected to the end of the main support spring, a second fitting ring fixedly connected to the second fitting spring, the second fitting spring being tangent to the second fitting ring, and the second fitting ring being parallel to the first fitting ring.
[0010] Preferably, the top surface of the built-in groove has openings at both ends, and the pressing frame is slidably connected to the openings.
[0011] Preferably, a through hole is formed on the top surface of the built-in groove, the through hole and the positioning groove are connected, and the locking rod is slidably connected to the through hole.
[0012] Preferably, limiting blocks are fixed to both sides of the slider, and limiting grooves are opened on both sides of the built-in groove, with the limiting blocks slidably connected to the limiting grooves.
[0013] Preferably, the vertical cross-sectional shape of the pressing frame is an inverted U-shape.
[0014] Preferably, a positioning rod is fixedly connected to the bottom surface of the mounting groove, and a positioning hole is opened on the bottom surface of the connecting block, with the positioning hole slidably connected to the positioning rod.
[0015] Preferably, the first and second bonding rings are made of carbon spring steel wire.
[0016] Preferably, the first and second fitting rings have the same diameter; the first and second fitting springs have the same diameter.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This utility model, by setting up a hook frame, positioning groove, positioning block, card hole, spring, slider, card rod, pressing frame, etc., can fix and install multiple hooks through the cooperation of positioning groove and positioning block and the cooperation of card rod and card hole, which facilitates the installation and removal of hooks, and makes it easy to disassemble and replace hooks individually if they are damaged during use.
[0019] The spring in this invention comprises a supporting spring, a first contact spring, and a first contact ring, with each component working in concert. Because the first contact spring has a larger ring diameter and shorter ring spacing, the force-bearing area of the individual spring is increased, allowing for faster pressure transmission under external force. By incorporating a main supporting spring, whose smaller ring diameter and longer ring spacing allow for perpendicular force distribution between the rings, resisting the impact of external pressure and increasing the spring's rebound distance. This shortens the spring's rebound distance and reduces the rebound feedback time.
[0020] By incorporating a second contact spring, when force reaches the second contact spring, the force-bearing surface narrows, which can reasonably redirect the pressure focus point, allowing the spring force to be transmitted along the designed path, reducing resonance caused by the spring being stressed, thereby reducing noise generation, concentrating the force to the bottom of the spring, and recovering external impact pressure.
