Description
Technical field
The utility model belongs to technical field of fastening, particularly relates to a kind of high ferro locking clamp female.
Background technique
Card is female as a kind of comparatively common fastening piece, and the structural strength of itself needs to be guaranteed.At present, fastening piece conventional on market adopts traditional turning process, and structural strength is poor, and the manufacture cycle is long and cost of production is high.In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.
Such as, Chinese patent literature discloses a kind of high strength lock jack panel [application number: 201120572297.0], comprise nut body, internal thread is provided with in the screw of described nut body, the axially extended of described nut body has the excessive portion of ring, and the internal diameter in the excessive portion of described ring is slightly less than the internal diameter of nut body; It has the advantage that structure is simple, easy to manufacture, cost is low, against shock, locking intensity are high, safe and reliable.
Above-mentioned scheme improves the subproblem of prior art to a certain extent, but the program also at least exists following defect: design unreasonable, still there is structural strength difference, the manufacture cycle long and technical problem that cost is high.
Model utility content
The purpose of this utility model is for the problems referred to above, and provide a kind of design more reasonable, structural strength is high, and performance is good, and the high ferro locking clamp that with short production cycle and cost of production is low is female.
For achieving the above object, the utility model have employed following technical proposal: this high ferro locking clamp main bag draws together tubular cylindrical shell, described inner barrel has the passage axially run through, described barrel outer surface comprise coaxial arrange top, middle part, bottom, the bottom be provided with described in the first wrench faces, described top is provided with the second wrench faces, and described cylindrical shell is made up of metallic material.
In above-mentioned high ferro locking clamp mother, described high ferro locking clamp mother is made by the one-body molded mode of cold hobbing.
In above-mentioned high ferro locking clamp mother, the first described wrench faces and the second wrench faces stagger and arrange.
In above-mentioned high ferro locking clamp mother, the first described wrench faces and the second wrench faces are the coaxial octagon wrench faces arranged.
In above-mentioned high ferro locking clamp mother, the first described wrench faces is connected by the first inclined-plane with middle part, and the first described inclined-plane and wire clamp angle, cylindrical shell axle center are 30 °.The second described wrench faces is connected by the second inclined-plane with middle part, and the second described inclined-plane and wire clamp angle, cylindrical shell axle center are 30 °.
In above-mentioned high ferro locking clamp mother, described passage and joint, upper/lower terminal face are through chamfering, and described chamfering is 45 °.
In above-mentioned high ferro locking clamp mother, described channel diameter and barrel diameter ratio are 1:1.8.
In above-mentioned high ferro locking clamp mother, described top, middle part, lower length ratio are 1:1:1.
Compared with prior art, the advantage of this high ferro locking clamp mother is: 1, design is more reasonable, and structural strength is high, and performance is good.2, with short production cycle, spillage of material is little, and cost of production is low.
Accompanying drawing explanation
Fig. 1 is the plan view that the utility model provides.
Fig. 2 is the left view that the utility model provides.
Fig. 3 is the plan view that the utility model provides.
In figure, cylindrical shell 1, inclined-plane 6, passage 2, first wrench faces 3, second wrench faces 4, first inclined-plane 5, second, top 7, middle part 8, bottom 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As Figure 1-3, this high ferro locking clamp main bag draws together tubular cylindrical shell 1, described cylindrical shell 1 inside has the passage 2 axially run through, described cylindrical shell 1 outer surface comprises top 7, middle part 8, bottom 9, the bottom 9 be provided with described in the first wrench faces 3, described top 7 is provided with the second wrench faces 4, and described cylindrical shell 1 is made up of metallic material.
Concrete, described high ferro locking clamp mother is made by the one-body molded mode of cold hobbing.The first described wrench faces 3 and the second wrench faces 4 stagger and arrange.Here the first wrench faces 3 and the second wrench faces 4 are the coaxial octagon wrench faces arranged.This first wrench faces 3 is connected by the first inclined-plane 5 with middle part 8, and the first described inclined-plane 5 is 30 ° with shaft axis angle.The second described wrench faces 4 is connected by the second inclined-plane 6 with middle part 8, and the second described inclined-plane 6 is 30 ° with shaft axis angle.
At passage 2 with joint, upper/lower terminal face through chamfering, described chamfering is 45 °.Described passage 2 diameter and cylindrical shell 1 diameter proportion are 1:1.8.Described top 7, middle part 8, bottom 9 length ratio are 1:1:1.
In the present embodiment, the high ferro locking clamp made by the one-body molded mode of cold hobbing mother has higher intensity, and the efficiency of simultaneously producing is high, with short production cycle and in process of production, spillage of material is less, and cost expenses is less.A wrench faces is respectively provided with in the upper and lower of cylindrical shell 1, simultaneously in passage 2 and end face joint chamfering, user-friendly.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as cylindrical shell 1, inclined-plane 6, passage 2, first wrench faces 3, second wrench faces 4, first inclined-plane 5, second, top 7, middle part 8, bottom 9 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
