Description

A kind of combined sleeve die nut
Technical field
The utility model provides a kind of a kind of combined set used for being used to load and unload built-up jig band special shoulder primary nut Cylinder die nut, belongs to built-up jig field.
Background technology
In built-up jig assembling process, achieved a fixed connection between element by key, screw bolt and nut, spanner is to tighten Or a kind of common instrument of nut is screwed out, suitable species, sleeve die nut need to be selected according to component structure and fixture space It is relatively conventional one kind, needs to be commonly used in assembling process.Original sleeve die nut full-length is 160CM, In built-up jig assembling process, this kind of spanner is selected in the assembling of the similar structural element such as left and right angle bar more, but ought need to assemble specification When left and right angle bar for 180,240,300 or similar structure, the spanner need to pass through because self structure limitation can not be used flexibly Vibration flexible handle realizes assembly and disassembly, and spanner is at most only capable of 180 ° of rotation and discontinuous every time, assembling visual angle it is bad and It is very inconvenient in the case that screw-in thread turns is more, waste time and energy.
Utility model content
The problem of existing for prior art, the utility model to former handle and tappet head by carrying out local improvement, knot Standardization screw, nut composition not only can be used alone but also the combined sleeve die nut used, and it remains the work(of former spanner Can, single-piece service efficiency is given full play to, when demand, can become simplified as special product quickly by two pieces wrench group, Practicality is extremely strong, solve assemble profound element when box spanner fall short of, in-convenience in use problem.
In order to achieve the above object, the technical solution of the utility model is:
A kind of combined sleeve die nut, including interior six sides tappet head 1, sleeve 2, straight pin 3, flexible handle 4, spiral shell Female A5, screw 6, nut B7, hole A8, hole B9, hole C10, hole D11, hole E12.Described interior six sides tappet head 1 is six in outside cylinder Square groove pore structure, its radial direction are provided with connection through hole at two, hole A8, hole B9.Described sleeve 2 is six square toes outside both ends Circular tube structure, and connection through hole is provided with one group of center side of six square toes outside respectively, one end is hole C10, the other end is Hole D11;Outer six square toes of described one end of sleeve 2 coordinate with interior six sides tappet head 1 to be installed, and ensures that hole C10 aligns with hole A8, institute There is a hole E12 on the pipe for the other end of sleeve 2 stated, described hole C10 diameter is slightly larger than hole A8.The described mistake of straight pin 3 It is full of and coordinates press-in hole A8, through hole C10, six side's tappet heads 1 has micro amplitude of fluctuation in guarantee, are advantageous to the biography of screwing force Lead.After described one end of flexible handle 4 passes through the hole E12 on sleeve 2, pass through the screw thread that nut A5 screws in the end of flexible handle 4 On bar, flexible handle 4 vibration but can not drop arbitrarily in the E12 of hole.
When two sets of combined sleeve die nuts combine, the movable hand on first combined sleeve die nut After handle 4 and nut A5 are laid down, the interior six sides tappet head 1 of front end and first can groups on second combined sleeve die nut Outer six square toes of box-like sleeve die nut rear end coordinate installation, ensure the hole B9 of second combined sleeve die nut with The hole D11 alignment of first combined sleeve die nut, screw 6 screw on nut B7 after passing through hole B9 and hole D11, realize solid Fixed connection.
The beneficial effects of the utility model are:There is the structure of outer six square joint by the way that original sleeve is improved into both ends Length sleeve is simultaneously designed as 180CM by form in the case where not influenceing intensity itself, inside brand-new one on six side's tappet heads Connecting hole is combined, while flexible handle is changed to detachable, makes the utility model directly left and right below 180 in specification It is used alone in the assembling of the elements such as angle bar, two sets of assemblings for combining the profound element that can then meet specification 180~300.This practicality New to compensate for old-fashioned sleeve die nut inconvenient for use in the case of insufficient space the shortcomings that, utilization rate is high, can be when normal Advise sleeve die nut to be used alone, when needed can use two sets of spanner Rapid Combinations into deep socket again, it is convenient fast Victory, securely and reliably, resource consumption is saved to a certain extent, be an exquisiteness, practicality, convenient utility model.
Brief description of the drawings
Fig. 1 is the assembling stereogram of single set combined sleeve die nut;
Fig. 2 is the assembling stereogram of double set combined sleeve die nuts;
Fig. 3 is the application schematic diagram of combined sleeve die nut;
In figure:Six side's tappet head in 1,2 sleeves, 3 straight pins, 4 flexible handles, 5 nut A, 6 screws, 7 nut B, 8 hole A, 9 Hole B, 10 hole C, 11 hole D, 12 hole E.
Embodiment
The utility model is described further below in conjunction with embodiment.
As shown in figure 1, the interior six sides tappet head 1 of combined sleeve die nut is six square groove pore structures in outside cylinder, Its radial direction is provided with connection through hole at two, hole A8, hole B9.Sleeve 2 is the circular tube structure of six square toes outside both ends, and exists respectively Connection through hole is provided with one group of center side of outer six square toes, one end is hole C10, the other end is hole D11;One end of sleeve 2 Outer six square toes coordinate with interior six sides tappet head 1 to be installed, and ensures that hole C10 aligns with hole A8, has a hole on the other end pipe of sleeve 2 E12.Straight pin 3 is interference fitted press-in hole A8, and through hole C10, six side's tappet heads 1 have micro amplitude of fluctuation in guarantee.It is living After the one end of fixed handle 4 passes through the hole E12 on sleeve 2, screwed in by nut A5 on the threaded rod at the end of flexible handle 4, movable hand Handle 4 vibration but can not drop arbitrarily in the E12 of hole.
As shown in Fig. 2 when two sets of combined sleeve die nuts combine, first combined sleeve die nut On flexible handle 4 and nut A5 lay down after, on second combined sleeve die nut the interior six sides tappet head 1 of front end with Outer six square toes of first combined sleeve die nut rear end coordinate installation, ensure that second combined sleeve hexagonal is pulled The hole B9 of hand aligns with the hole D11 of first combined sleeve die nut, and screw 6 screws on spiral shell after passing through hole B9 and hole D11 Female B7, achieves a fixed connection.
In use, according to wanting the specification of connecting element to be selected, when sleeve die nut needs built-in length to be less than During 180CM, single set combined sleeve die nut can be used directly;When sleeve die nut needs built-in length to be more than 180CM and when being less than 300CM, single built-in length deficiency for covering combined sleeve die nut, then needs the spanner by two sets to enter Row is applied in combination.Because the accessory structure of combined sleeve die nut is simple, easy to process and connector is standard component, therefore It is convenient to be changed after service wear, can disassembly and assembly at any time according to demand, fully demonstrated the utilization rate and composability of spanner Energy.
The utility model has been applied in the assembly and disassembly of built-up jig, convenient to use, and reflection effect is good.
