Abstract
The utility model discloses a kind of chain-type lock machine hook bolt, including handpiece case, the both ends of the handpiece case are respectively equipped with the first bolt and the second bolt, the other end of first bolt and the second bolt is separately installed with first gear and second gear, is connected between first gear and second gear by chain.The utility model will lock frame head apparatus and be changed to all be connected with movable bolt up and down while connect upper and lower bolt with chain；When tearing head open, handpiece case dimidiation is balanced to both sides and separated, and substantially increases practicality.
Description
Technical field
It the utility model is related to a kind of lock frame head apparatus, specifically a kind of chain-type lock machine hook bolt.
Background technology
Wire rod refers to a diameter of 5-22mm hot rolled circular steel or the profile iron of this suitable section.Because being handed in the form of wire rod
Goods, therefore wire rod is commonly referred to as again.Wire rod section girth very little, a diameter of 5-13mm of common product specification.According to the difference of milling train
High-speed rod can be divided into（High line）With common wire (general line）Two kinds.Wire rod typically uses ordinary carbon steel and Fine Steel Casting iron system
Into.Different with purposes according to steel distribution catalogue, wire rod includes ordinary low-carbon steel hot rolling wire rod, Fine Steel Casting iron wire rod, carbon
Plain welding rod wire rod, quenched screw wire rod, steel wire rope wire rod processed, piano wire wire rod and stainless steel wire rod etc..
Head need to be opened to mold changing when production different size or the wire rod of color and clean head, under traditional locks frame head apparatus
Face is fixing bolt, is above movable bolt, and when tearing head open, handpiece case is using following bolt as fulcrum, and top half is to both sides
Separately, wasted time and energy during production operation.
Utility model content
The purpose of this utility model is to provide a kind of chain-type lock machine hook bolt, to solve to propose in above-mentioned background technology
The problem of.
To achieve the above object, the utility model provides following technical scheme：
A kind of chain-type lock machine hook bolt, including handpiece case, the both ends of the handpiece case are respectively equipped with the first bolt
With the second bolt, the other end of first bolt and the second bolt is separately installed with first gear and second gear, the first tooth
It is connected between wheel and second gear by chain.
As further program of the utility model：First bolt and the second bolt connect with handpiece case for screw thread
Connect.
As further program of the utility model：The first gear and second gear are installed on the same of handpiece case
Side.
Compared with prior art, the beneficial effects of the utility model are：Lock frame head apparatus is changed to all use movable screw up and down
Tether and connect while upper and lower bolt is connected with chain；When tearing head open, handpiece case dimidiation is balanced to both sides and separated,
Substantially increase practicality.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is side structure schematic view of the present utility model.
In figure：1- handpiece cases, the bolts of 2- first, the bolts of 3- second, 4- first gears, 5- second gears, 6- chains.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~2, in the utility model embodiment, a kind of chain-type lock machine hook bolt, including handpiece case 1, institute
The both ends for stating handpiece case 1 are respectively equipped with the first bolt 2 and the second bolt 3, the first bolt 2 and the second bolt 3 with outside head
Shell 1 is threaded connection, and the other end of the bolt 3 of the first bolt 2 and second is separately installed with first gear 4 and second gear 5,
The first gear 4 and second gear 5 are installed on the same side of handpiece case 1, pass through between first gear 4 and second gear 5
Chain 6 is connected.
Lock frame head apparatus is changed to all be connected with movable bolt up and down upper and lower bolt connected with chain simultaneously；Tearing open
During head, handpiece case dimidiation is balanced to both sides and separated, and substantially increases practicality.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
The above is only preferred embodiment of the present utility model, it is noted that for those skilled in the art,
Without departing from the concept of the premise utility, several modifications and improvements can also be made, these should also be considered as this practicality
New protection domain, these are all without the effect and practical applicability for influenceing the utility model implementation.
