Abstract
The utility model discloses a kind of Combined type screw, it is characterized in that: comprising: nut (1), screw rod (2), conehead (3); Described nut (1) is made up of the crown (11) and cap body (12) being cast into integrative-structure; Be threaded connection between described cap body (12) and screw rod (2), be threaded connection between described screw rod (2) and conehead (3); Described crown (11) and cap body (12) are provided with the cross bore (111) running through crown (11) and cap body (12); Described screw rod (2) is provided with the cross recess (21) measure-alike with described cross bore (111); The dimensional range that described cross recess (21) stretches into screw rod (2) is three places of to four/2nds parts of screw rod (2) length.By adopt technique scheme, the utility model have economize on resources, protection of the environment, be convenient to pack and transport advantage.
Description
Technical field
The utility model relates to component of machine technical field, particularly relates to a kind of Combined type screw.
Background technique
Screw is one of component of machine of often using in daily life of people, in recent years, along with the high speed development of society, the use amount of screw increases fast, at present, traditional screw is made up of integrated casting technique mostly, and the screw of this structure has processing advantage simple, easy to use.
But found by long-term use link, there is following defect in the screw of said structure: one, when some parts (such as conehead, nut or screw rod) of screw are damaged, this screw then needs to be replaced by new screw, therefore, have a large amount of metallic material to be every year wasted, above-mentioned discarded metallic material can produce impact greatly to environment simultaneously; Two, because integrated screw sizes is long, it is not too convenient therefore to pack and carry; So, design and develop a kind of screw that can overcome above-mentioned defect and seem it is particularly important.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of can protection of the environment, economize on resources, be convenient to pack and carrying Combined type screw.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of Combined type screw, comprising: nut (1), screw rod (2), conehead (3); Described nut (1) is made up of the crown (11) and cap body (12) being cast into integrative-structure; Be threaded connection between described cap body (12) and screw rod (2), be threaded connection between described screw rod (2) and conehead (3); Described crown (11) and cap body (12) are provided with the cross bore (111) running through crown (11) and cap body (12); Described screw rod (2) is provided with the cross recess (21) measure-alike with described cross bore (111); The dimensional range that described cross recess (21) stretches into screw rod (2) is three places of to four/2nds parts of screw rod (2) length.
Preferably, the utility model additionally uses following technological scheme:
Further: the size that described cross recess (21) stretches into screw rod (2) is 1/2nd of screw rod (2) length.
Further: the size that described cross recess (21) stretches into screw rod (2) is three of four parts of screw rod (2) length.
The advantage that the utility model has and good effect are:
One, by adopting technique scheme, in the utility model Combined type screw three parts between all adopt screw thread to connect, so in use, if find that some parts of screw are damaged, can replace with corresponding new parts in time, and not need to carry out entirety replacement, therefore compared with conventional art, a large amount of resources can be saved, and then reduce to the pollution of environment;
Two, by adopting technique scheme, in the utility model Combined type screw three parts between all adopt screw thread to connect, so in the process of packing or carry, above-mentioned three parts can be carried out split packaging and transport, because nut and screw rod do not exist most advanced and sophisticated position, therefore easily carry out packing and transporting, after split simultaneously, the volume of conehead is compared with the volume of the whole screw of tradition, and volume is smaller, therefore packs and transport also more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is nut structure schematic diagram of the present utility model;
Fig. 3 is screw-rod structure schematic diagram of the present utility model;
Wherein: 1, nut; 11, crown; 111, cross bore; 12, cap body; 2, screw rod; 21, cross recess; 3, conehead.
Embodiment
For model utility content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of Combined type screw, comprising: nut 1, screw rod 2, conehead 3; Described nut 1 is made up of the crown 11 and cap body 12 being cast into integrative-structure; Be threaded connection between described cap body 12 and screw rod 2, be threaded connection between described screw rod 2 and conehead 3; Described crown 11 and cap body 12 are provided with the cross bore 111 running through crown 11 and cap body 12; Described screw rod 2 is provided with the cross recess 21 measure-alike with described cross bore 111; Because traditional cross bore 111 is more shallow, therefore along with the increase of access times, the corner angle of tradition cross bore 111 are worn away, and in order to overcome above-mentioned defect, in this specific embodiment, cross recess 21 stretches into three places that the dimensional range of screw rod 2 is to four/2nds parts of screw rod 2 length.
Use principle of the present utility model for: successively nut 1, screw rod 2, conehead 3 are connected according to the position relationship shown in Fig. 1, then cross bore 111 is inserted with screwdriver or spanner, and then stretch into cross recess 21 and rotate, finally realize the fastening of Combined type screw or dismounting.
Preferably, the cross recess 21 in above-mentioned specific embodiment is of a size of:
Further: the size that cross recess 21 stretches into screw rod 2 is 1/2nd of screw rod 2 length.
Further: the size that cross recess 21 stretches into screw rod 2 is three of four parts of screw rod 2 length.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
