[0002] Resistors are generally called resistors in daily life. It is a current limiting component. After the resistor is connected to the circuit, the resistance value of the resistor is fixed, usually with two pins. It can limit the current through the branch it is connected to. In the process of connecting the resistor, due to the needs of the line, the resistor often needs to be suspended and set. Traditional resistors are suspended on the line without additional fixation, which is prone to loose connection. For this reason, we propose a hanging ear type hanging resistor to solve the above problem. Utility Model Content

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Reference Figures 1 - 3A hanging ear type hanging resistor comprises a resistor 1, both ends of the resistor 1 are connected with pins 2, a hanging platform 4 is fixedly arranged on the upper wall of the resistor 1, and the hanging platform 4 is connected to the resistor 1 through a connecting mechanism, the connecting mechanism comprises a connecting block 3, the connecting block 3 is fixedly arranged on the upper wall of the resistor 1, a slot 10 corresponding to the connecting block 3 is provided on the lower wall of the hanging platform 4, a fixing mechanism corresponding to the connecting block 3 is provided in the slot 10, and the fixing mechanism comprises two card blocks 11, and two side walls of the slot 10 are symmetrically provided with two telescopic slots 12 corresponding to the card blocks 11, and the two card blocks 11 are respectively slidably arranged in the two telescopic slots 12 ... The blocks 11 are connected to the inner wall of the telescopic slot 12 through a spring 13, and a card slot corresponding to the card block 11 is opened on the side walls of both sides of the connecting block 3. The side walls of the two card blocks 11 close to the opening of the slot 10 are inclined, and the two card blocks 11 are provided with a corresponding toggle mechanism, and the toggle mechanism includes two levers 14, and the two levers 14 are respectively fixed on the side walls of the two card blocks 11, and the two levers 14 are slidably penetrated through the lower wall of the hanging platform 4. The lower wall of the hanging platform 4 is symmetrically provided with two strip-shaped sliding openings corresponding to the levers 14, and the ends of the two levers 14 away from the card blocks 11 are fixedly provided with extension plates 15, and the two extension plates 1 5 extends out of the hoisting platform 4, and two lifting ears 9 are symmetrically slidably arranged on the hoisting platform 4. The two lifting ears 9 are slidably arranged on the hoisting platform 4 through the slider 8. A slide groove 5 corresponding to the two sliders 8 is opened on the hoisting platform 4, and a control mechanism corresponding to the lifting ears 9 is arranged in the slide groove 5. The control mechanism includes a threaded rod 6, which is rotatably arranged in the slide groove 5, and the threaded rod 6 rotates through the two sliders 8. The two sliders 8 are each provided with a threaded through hole corresponding to the threaded rod 6. The threads at both ends of the threaded rod 6 are arranged in opposite directions, and one end of the threaded rod 6 rotates through the side wall of the hoisting platform 4 and is fixedly connected with a rotating handle 7. By setting a clamping block 11, the hoisting is realized. The platform 4 is quickly installed on the resistor 1, so that the resistor 1 can be hoisted and fixed, and the problem of looseness during the hoisting connection process is avoided. The control of the card block 11 is achieved through the cooperation of the extension plate 15 and the lever 14. The two card blocks 11 can be driven to slide out of the slot by tossing the lever 14, thereby releasing the restriction and fixation of the connection block 3 in the slot 10, so that the hoisting platform 4 can be quickly disassembled from the resistor 1, which is convenient for the resistor 1 to be connected on the line that does not need hoisting. The cooperation of the threaded rod 6 and the slider 8 can realize the rapid adjustment of the distance of the lifting ear 9, so that the distance of the lifting ear 9 can adapt to the hooks at different distances, which greatly improves the adaptability of the device.

[0017] In the utility model, when installing the resistor 1, when the resistor 1 does not need to be hoisted, it is only necessary to push the extension plate 15 to drive the lever 14 to slide, and then the two clamping blocks 11 can be driven to slide out of the slots, thereby releasing the restrictive fixation of the connecting block 3 in the slot 10, so that the hoisting platform 4 can be quickly removed from the resistor 1 to avoid the hoisting platform 4 occupying space. When the resistor 1 needs to be hoisted, it is only necessary to install and fix the hoisting platform 4 on the resistor 1, and then rotate the threaded rod 6 to drive the two lifting ears 9 to move to adapt to the hook distance, so as to complete the hoisting and fixing of the resistor 1, and effectively avoid the problem of the resistor 1 being loose during the hoisting process.
