Embodiment 1

[0034] see Figure 1~2 , in Embodiment 1 of the present invention, a composite carbon brush for electric picks, including a length-adjustable installation sleeve, a carbon brush 3, an elastic sliding seat 2 and a collision piece 5; a cavity is provided inside the installation sleeve, and the hollow The cavity is provided with an opening to facilitate the leakage of the carbon brush 3; the elastic sliding seat 2 is elastically arranged in the inner cavity of the installation sleeve; the carbon brush 3 is detachably arranged on the elastic sliding seat 2; such setting is convenient for the carbon brush 3 Replacement; the alarm mechanism is arranged on the installation sleeve, and when the length of the carbon brush 3 is shortened to unusable, an alarm signal is sent. The elastic sliding seat 2 is slidably arranged inside the installation sleeve, and the installation sleeve is provided with a locking mechanism for locking the two end positions of the elastic sliding seat 2 . In ...

Embodiment 2

[0037] see Figure 2-4 , The main difference between Embodiment 2 and Embodiment 1 is that the carbon brush 3 is spliced ​​in two pieces, and the two pieces are bonded by glue.

[0038] As a preferred embodiment of the present invention, the installation cover includes a first installation shell 1 and a second installation shell 4, the second installation shell 4 is arranged on the first installation shell 1, and the height of the second installation shell 4 is Adjustable settings. Specifically, the second installation shell 4 can be installed on the first installation shell 1 through threads, and the outer side of the first installation shell 1 can be provided with multi-level card slots, and the second installation shell 4 can be locked on different card slots. , to achieve different height adjustments. External threads are provided on the outside of the first installation shell 1 , and internal threads are provided on the second installation shell 4 . The second installa...

Abstract

The invention discloses a composite carbon brush for an electric pick, which relates to the technical field of electrical accessories; it comprises: a length-adjustable installation sleeve, a cavity is arranged inside the installation sleeve; an elastic sliding seat is elastically arranged in the cavity inside the installation sleeve, The elastic sliding seat is slidingly arranged inside the installation sleeve, and the installation sleeve is provided with a locking mechanism for locking the two end positions of the elastic sliding seat; the carbon brush is detachably arranged on the elastic sliding seat; The installation sleeve is equipped with an alarm structure, and when the length of the carbon brush is shortened to unusable, an alarm signal is sent; and, the interference sheet is arranged on the installation sleeve, and the interference sheet is electrically connected to the carbon brush. The present invention can further explain the replacement of the carbon brush by providing an alarm mechanism; the carbon brush is detachably arranged on the elastic sliding seat, which is convenient for replacement. The invention has the advantages of convenient use, wide application range, alarm function and convenient replacement of carbon brushes.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a composite carbon brush for an electric pick. Background technique [0002] The carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery. When the motor rotates, the electric energy is transmitted to the coil through the commutator. As a sliding contact, carbon brushes are widely used in many electrical equipment. Traditional carbon brushes are generally made of pure carbon plus coagulant. The shape is generally square, with large and small volumes. There are wires leading out from the top. The wires are welded on the joint, and the other side of the joint is fixed on the brush socket by a connecting spring. . [0003] After the carbon body in the carbon brush wears out, the length of the carbon brush will be insufficient, which will cause the circuit to fail, and t...
