The embodiment of the application discloses a throat locking structure.

Referring to fig. 1, an embodiment of a throat structure provided in an embodiment of the present application includes:

a fixed seat 11, a screw 13 and a clamping block 12; an open slot is arranged on the fixed seat 11; the screw 13 is rotatably arranged on the fixed seat 11 and is in threaded fit with the fixed seat 11, and a first end of the screw 13 extends into the open slot and is connected with the clamping block 12; a clamping cavity is formed between the clamping block 12 and the fixed seat 11.

Specifically, for example, according to the use principle, the screw 13 is rotated first, so that the screw 13 is in threaded rotation fit with the fixed seat 11 to drive the fixed seat 11 to move, and further, the distance between the fixed seat 11 and the clamping block 12 is increased, and the requirement that an angle steel cross arm, a channel steel cross arm, a lead and the like can be clamped into the clamping cavity through an open slot is met; at this moment, the screw rod is reversed again to make fixing base 11 take place opposite removal, make fixing base 11 and grip block 12 between can press from both sides tight angle steel cross arm or channel-section steel cross arm etc. thereby realize fixedly, dismantle if only need on fixed basis toward the orientation of dismantling rotate screw rod 13 can, do not specifically do too much to describe again. In this embodiment, the first end of the screw 13 is rotatably connected and matched with the clamping block 12, so that when the clamping block 12 contacts with an angle iron cross arm or a channel steel cross arm, the influence on the rotation of the screw 13 is reduced.

The above is a first embodiment of a throat structure provided in the present application, and the following is a second embodiment of a throat structure provided in the present application, specifically referring to fig. 1.

A throat locking structure comprises a fixed seat 11, a screw 13 and a clamping block 12; an open slot is arranged on the fixed seat 11; the screw 13 is rotatably arranged on the fixed seat 11 and is in threaded fit with the fixed seat 11, and a first end of the screw 13 extends into the open slot and is connected with the clamping block 12; a clamping cavity is formed between the clamping block 12 and the fixed seat 11.

Further, a clamping piece 121 is arranged on the clamping block 12; the latch 121 is slidably engaged with the fixing base 11 along the clamping direction of the clamping block 12. Clamping stop 121 that sets up can prevent that screw 13 from driving grip block 12 when rotating and rotating, and the influence is used, also makes fixing base 11 better with grip block 12's degree of cooperation, improves the stability of centre gripping and the convenience of use.

Further, the fixing base 11 includes a bottom plate portion 111, a side plate portion 112, a stopper plate portion 114, and a top plate portion 113; the first end of the side plate 112 is vertically connected to the bottom plate 111, and the second end is vertically connected to the top plate 113; the first end of the limiting plate part 114 is vertically connected with the top plate part 113; an opening slot is defined by the bottom plate part 111, the side plate part 112, the top plate part 113 and the limit plate part 114; the screw 13 movably penetrates through the bottom plate part 111 and is in threaded connection with the bottom plate part 111; a clamping cavity is defined by the clamping block 12, the top plate part 113, the side plate part 112 and the limiting plate part 114; the latch 121 is slidably engaged with the side plate 112. Wherein spacing board portion 114 can make the centre gripping chamber that forms more closed, and the centre gripping is fixed more firmly like this, and fixing base 11 is whole can be C shape structure, makes things convenient for the centre gripping of angle steel/channel-section steel cross arm to fix, can also be certainly be the hook-type, makes things convenient for the centre gripping of wire to fix. The above structure is a specific embodiment of the present application, and those skilled in the art can make appropriate changes based on the above structure, and do not specifically limit the present application.

Furthermore, taking the structure of the fixing base 11 as an example, the side plate portions 112, the limiting plate portion 114 and the top plate portion 113 can be provided with hollow holes, so that the overall mass can be reduced, and the operation is more convenient.

Further, the engaging pieces 121 are specifically two; the two locking pieces 121 are symmetrically attached to the holder 12, and the two locking pieces 121 sandwich the side plate portion 112 and are in sliding contact with the side plate portion 112. The clamping parts 121 may be L-shaped, and are not limited in particular, and may be integrally connected to the clamping block 12, and the two clamping parts 121 are used to realize the fit with the side plate part 112, and further realize the sliding fit with the fixing base 11. Of course, taking the side plate 112 with a hollow hole as an example, the locking member 121 may extend into the hollow hole to match with the side plate 112, and the hollow hole structure on the corresponding side plate 112 may be a rectangular hole groove. Those skilled in the art can make appropriate changes based on the above without limitation.

Further, the second end of the screw 13 in this application can be provided with an inner concave hole (not shown) with a non-circular interface, and a magnetic part such as a magnet can be embedded in the inner concave hole. Thus, the rotating rod on the operating rod is conveniently connected with the operating rod and synchronously rotates. Magnet can increase with iron dwang or have the cooperation between the dwang of magnet rather than complex more firm, it is more convenient to dismantle simultaneously. Of course, other connection methods may be adopted for connection, and are not limited specifically.

According to the technical scheme, the screw rod 13 and the fixing seat 11 are matched in a rotating mode, so that the size of the clamping cavity formed between the clamping block 12 and the fixing seat 11 is adjusted, and fixing or dismounting operation is completed. Wholly collocation action bars etc. can be used for driving screw 13 pivoted multiplexer utensil, can realize convenient quick fixed and dismantle the operation, improve the operating efficiency.

While the above detailed description has been directed to a throat lock structure, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
