Abstract

The utility model discloses a galvanized iron plate bracket component, including support main part and bakelite brush box, the window has been seted up to the side of support main part, and the bakelite brush box passes through the window and installs in the support main part, the window includes the side window limit on upper window limit, lower window limit and both sides, and the both ends on upper window limit and lower window limit all are equipped with the dogtooth structure, the length an of dogtooth structure is no longer than the wall thickness of bakelite brush box. The utility model discloses utilize the both sides wall of bakelite carbon-brush box, just only set up the dogtooth structure that is no longer than bakelite carbon-brush box wall thickness at the both ends on upper and lower window limit, make it after the assembly, the extrusion force atress that interference fit leads to has effectively avoided the protruding deformation in upper and lower edges of bakelite carbon-brush box on the both sides wall of bakelite carbon-brush box.

Description

Galvanized iron sheet bracket component

Technical Field

The utility model belongs to the technical field of the motor support and specifically relates to a zinc-plated iron plate bracket component.

Background

The upper window edge and the lower window edge of a window where the existing galvanized iron plate support is connected with the bakelite carbon brush box are provided with convex tooth structures (as shown in figure 1) within the range exceeding the thickness of the side wall of the bakelite brush box, and because the bakelite carbon brush box is of a hollow structure and is in interference fit with the support, the upper bottom edge and the lower bottom edge of the bakelite carbon brush box, which are in contact with the upper window edge and the lower window edge, are easily extruded by the convex teeth and then protrude inwards (as shown in figure 2), so that the hole of the bakelite box is reduced, and certain influence is caused on the free movement of the carbon brush.

SUMMERY OF THE UTILITY MODEL

The utility model provides a galvanized iron plate bracket component which can ensure that the hole of the bakelite carbon brush box can not be reduced in order to overcome the defects.

The technical scheme of the utility model as follows:

the utility model provides a galvanized iron plate bracket component, includes support subject and bakelite brush box, and the window has been seted up to the side of support subject, and the bakelite brush box passes through the window and installs in support subject, the window includes the side window limit on upper window limit, lower window limit and both sides, and the both ends on upper window limit and lower window limit all are equipped with the dogtooth structure, the length an of dogtooth structure is no longer than the lateral wall thickness of bakelite brush box, promptly, upper and lower window limit only has set up the dogtooth structure in the position department that the bakelite brush box had the lateral wall to support, and these two positions are owing to there is the lateral wall support of brush box, therefore the dogtooth structure can not let the upper and lower base of brush box warp.

Preferably, the illustrated single side of the lobe configuration includes two lobes in sequential arrangement. Considering that the size of the bracket is different, the side wall thickness of the electric wood brush box is different, and the convex teeth arranged in the range not exceeding the side wall thickness of the electric wood brush box can not be limited by the number.

Preferably, the side face of the bakelite carbon brush box is in small clearance fit or transition fit with the side window edge of the window.

The beneficial effects of the utility model are that:

the utility model discloses utilize the both sides wall of bakelite carbon-brush box, just only set up the dogtooth structure that is no longer than bakelite carbon-brush box wall thickness at the both ends on upper and lower window limit, make it after the assembly, the extrusion force atress that interference fit leads to has effectively avoided the protruding deformation in upper and lower edges of bakelite carbon-brush box on the both sides wall of bakelite carbon-brush box.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

FIG. 1 is a schematic view of a window of a conventional galvanized iron sheet stand;

FIG. 2 is a schematic view of a prior art bakelite carbon brush box when raised;

fig. 3 is a schematic view of the present invention;

FIG. 4 is a schematic view of a single-sided bakelite brush cartridge removed;

FIG. 5 is an enlarged view of detail B of FIG. 3;

fig. 6 is an enlarged view of a portion a in fig. 4.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to be referred must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "connected", and the like are to be interpreted broadly, such as "connected", which may be a fixed connection including welding, riveting, bonding, and the like; or the detachable connection comprises a threaded connection, a key connection, a pin connection and the like; or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as a specific case by those skilled in the art.

The galvanized iron plate bracket component shown in fig. 3-6 comprises a bracket main body 1 and an electric wood carbon brush box 2, wherein a window 3 is arranged on the side surface of the bracket main body 1, the electric wood carbon brush box 2 is arranged in the bracket main body 1 through the window 3, the window 3 comprises an upper window edge 4, a lower window edge 5 and side window edges 6 on two sides, and the side surface of the electric wood carbon brush box 2 is in small clearance fit or transition fit with the side window edges 6 of the window 3. Go up the both ends on window limit 4 and lower window limit 5 and all be equipped with protruding tooth structure 7, bakelite carbon brush box 2 and window 3 are in protruding tooth structure department interference fit, protruding tooth structure 7 includes two at least teeth that arrange in proper order, and the total length a of all teeth is no longer than bakelite carbon brush box 2's wall thickness, promptly, upper and lower window limit has only just set up the protruding tooth structure in bakelite carbon brush box position department that has the lateral wall to support, and these two positions are owing to there is the lateral wall of carbon brush box to support, and after the assembly, the extrusion force that interference fit leads to can be atred on the both sides wall of bakelite carbon brush box, therefore the protruding tooth structure can not let the upper and lower base of carbon brush box warp.
