Disclosure of the invention
Based on the defect of above-mentioned bolt head fixed mode, the to-be-solved technical problem of the utility model is to provide one kind because the bolt head position takes place to hang and can conveniently adjust when wiping the door frame in door leaf product use.
The following is the technical proposal adopted by the utility model:
an adjustable bolt head is composed of bolt head, bolt head sleeve, locking screw and bolt head pull rod. The bolt head sleeve is sleeved outside the bolt head to support and fix the bolt head, one section of threaded hole is formed in the middle of the bolt head and used for connecting a bolt head pull rod and a locking screw, blind rivet holes are formed in two wings of the bolt head sleeve, the blind rivet is fixed on the door plate, the size of the bolt head pull rod is adjusted and locked by adjusting the position of the locking screw, and the bolt head is stretched out of the bolt head
The utility model has the advantages that: the bolt head can conveniently adjust the extending size of the bolt head when the bolt head wipes the frame due to the downward hanging of the door leaf when the door leaf is used.
(IV) description of the drawings
FIG. 1 is a sectional view of the present invention;
fig. 2 is a bottom view of the present invention.
(V) specific embodiment
Referring to fig. 1-2, the adjustable bolt head comprises a bolt head 1, a bolt head sleeve 2, a locking screw 3 and the like. A bolt head sleeve 2 for supporting and fixing is sleeved outside the bolt head 1, and a blind rivet hole 5 which is fixedly installed with the door panel is formed in the bolt head sleeve 2 and is fixed to the door panel through a blind rivet. In addition, a threaded hole is provided in the middle of the bolt head 1 for connecting the bolt head tension rod 4, a hexagonal socket wrench hole 1-1 is provided in the head of the bolt head 1 for adjusting the axial dimension of the bolt head 1 and the bolt head lever 4, a locking screw 3 is provided in the end of the hexagonal socket wrench hole 1-1 in the bolt head, and the axial position of the bolt head 1 and the bolt head lever 4 is locked by the clearance of the bolt head 4 thread and the bolt head 1 screw thread by abutting the locking screw 3 against the bolt head lever 4. The axial size of the bolt head pull rod 4 is adjusted and locked by adjusting the position of the locking screw 3, thereby realizing the adjustment of the position size of the bolt head extending out of the bolt head sleeve.
