Abstract

The utility model relates to a multi-steering tripod of loudspeaker, and is characterized in that a pivot-link bar is provided with a graft union in the axial directions of the left end and the right end respectively, with the two graft unions perpendicular to each other, which enables users to adjust the up and down, the left and the right movements according to requirements; a matching fixed base is jogged with the ring arrangement part of the pivot-link bar, which supplies a proper card catch bonding force in preliminary false localization, and avoids sliding or getting loose when the users adjusts angles; a rolling thread screw cap can be jogged with the thread teeth on the fixed base, which prevents the screw cap from moving when the bolt is adjusted.

Description

The loudspeaker foot rest of multi-steering

Technical field

The loudspeaker foot rest of the relevant multi-steering of the utility model.

Background technique

Fig. 1 is common loudspeaker foot rest three-dimensional exploded view, and with reference to shown in Figure 2, from figure, can know and find out, its main structure is made up of a bar 300 that pivotly joins that is provided with two-way joint, wherein, the pivoted hole 301a of two joints, the axis of 301b is to be the vertical setting of 90 degree, and respectively by a bolt 400 be pivoted fixed base 100 and joining base 200, though this kind structure can be reached basic multi-steering effect, but owing to must be about to earlier when rotating after bolt 400 pulls with nut 500 pines, just can be rotated, and when bolt 400 unscrewed, joining base 200 hub settings had the greater weight loudspeaker, and whole pivot-connecting position is rotated, thereby when causing the user to adjust loudspeaker to turn to, need the inconvenient phenomenon of the above operation of two people.

Because common loudspeaker foot rest structure has above-mentioned defective, the creator improves these shortcoming researchs, and generation of the present utility model has been arranged finally.

Summary of the invention

The problem that existing loudspeaker foot rest exists is that it can not directly rotate, and needs to rotate with nut by the pine bolt of pulling, and user's need above operation of two people and cause inconvenience when adjusting loudspeaker and turning to.

For addressing the above problem, the utility model is achieved through the following technical solutions:

A kind of loudspeaker foot rest of multi-steering, mainly by fixed base with pivotly join bar and combined, it is characterized in that:

Two fixed bases have outwards extended two placing parts, in the middle of two placing parts, form a conduit, this placing part appropriate position cutter is provided with two corresponding through holes, wherein, one placing part is equipped with circular tooth part on every side in the through hole inboard, another placing part then is provided with a recessed circular groove in the through hole outside, and is provided with the line tooth at recessed circular groove periphery;

Pivotly join bar respectively to the left and right two ends respectively extend a joining portion, and two joining portion are to be disalignment to vertical setting of relative 90 degree, the joining portion is provided with recessed circular groove, this recessed circular groove central position is provided with the through hole that runs through for screw, and is equipped with circular tooth part in recessed circular groove week;

By the said fixing seat and pivotly join the mutual inlay card engagement of circular tooth part between bar, and provided when position supposition suitable clip combination force, when making the user adjust required angle, needn't worry to rotate and rock, and can directly impose certain strength bending and adjust, and the situation generation that needn't worry that slippage is arranged or get loose.

Except above-mentioned essential features, also can add following technical characteristics:

Wherein, the through hole of above-mentioned placing part outwards protrudes out an annular groove, during for locking, and the bolt head of ccontaining locking.

Wherein, the roller line of roller line nut chow ring can be chimeric with line dentification one clip of recessed circular groove periphery.

Wherein, fixed base placing part and joint, bottom are provided with reinforced ribs, so as to strengthening overall structure.

Wherein, fixed base is set to the external form with the form fit of loudspeaker.

Improved prior art problems by technique scheme.The utility model compared with prior art, mainly pivotly join bar respectively to the left and right the two ends disalignment to respectively extending a joining portion, the axis at two joining portion is to be vertical setting of relative 90 degree, make loudspeaker can according to the user must angle, about the adjustment, left and right displacement, and the mutual inlay card of circular tooth part that cooperates fixed base and pivotly join between bar meshes, provided preliminary when position supposition suitable clip combination force, when being convenient to the user and adjusting required angle, needn't worry to rotate and rock, and can directly impose certain strength bending and adjust, and the situation generation that needn't worry that slippage is arranged or get loose.

Embodiment

For understanding detailed structure of the present utility model in depth, using effect, application principle, now enumerate specific embodiment conjunction with figs. work one and be described in detail as follows.

Fig. 1, Fig. 2 are common loudspeaker foot rest structure figure, its structure and the defective of using, as previously described, at this repeated description no longer.

Fig. 3 is the three-dimensional exploded view of the utility model one preferred embodiment, from figure, can be clear that, the utility model mainly is to pivotly join bar 2 by two fixed bases 1 and to be combined, wherein, 11 appropriate positions are provided with a plurality of recessed circular grooves 111 to fixed base 1 in the bottom, and recessed circular groove 111 central positions are provided with the through hole 112 that can supply screw (steel nail) to run through, and two placing parts 12 have outwards been extended, 13, at two placing parts 12, form a conduit 14 in the middle of 13, this placing

part

12,13 appropriate positions cutters is established the two corresponding holes 121 that pivotly join, 131, and placing

part

12,13 with 11 joints, bottom be provided with reinforced ribs 122,132, so as to strengthening overall structure, wherein, one placing part 12 is equipped with circular tooth part 123 around pivotly joining hole 121, and outwards protrude out an annular groove 124 in opposite side, 13 of another placing parts are provided with a recessed circular groove 133 pivotly joining 131 outsides, hole, and are provided with line tooth 134 at recessed circular groove 133 lateral margins; Pivotly join bar 2 respectively to the left and right two ends respectively extend a joining

portion

21a, 21b, and two joining

portion

21a, 21b is vertical setting of relative 90 degree, joining

portion

21a, 21b is provided with recessed circular groove 211, these recessed circular groove 211 central positions be provided with can be for bolt-through pivotly join

hole

212a, 212b, and be equipped with circular tooth part 213 in recessed 211 weeks of circular groove, wherein, joining

portion
