Description
Technical field
The present invention relates to a kind of mechanical structure, particularly relate to a kind of connection, fastening piece and supporting spanner structure thereof.
Background technique
Outer-hexagonal hook bolt connects the mechanical parts with a quasi-representative in fastening piece, is widely used in the All aspects of of producing and living.The large complicated mechanical system such as aeroengine, numerical control machining center is all the important application of outer-hexagonal hook bolt, but because such mechanical system structure is complicated, volume is large, when carrying out routine to it and disassembling inspection, often have that some angular position are special, staff is difficult to touch the bolt reached, the special bolt in these positions is easy to come off and falls into mechanical system inside disassembling in process, and be not easy to take out, the bolt fallen into brings the impact that hidden danger is even more serious can to the normal work of mechanical system.Normally used outer-hexagonal hook bolt except having for except dismounting hexagonal prism shape, can utilize structure without other at nut place, and common supporting spanner only can ensure to be dismantled smoothly, and does not possess clamping, locking function, is difficult to bolt incidentally to take out.For the dismounting situation that such class is more special, lack the comparatively effective link of one and supporting spanner structure thereof at present.
Summary of the invention
The object of the invention is to be not easy to the dismounting situation of taking out for an above-mentioned class link, propose a kind of effectively can prevent coming off outer-hexagonal hook bolt and supporting spanner structure, this structure has the advantages such as easy to use, compact, connection be reliable.
Technical solution of the present invention is, a kind of Drop-proof connects and fastening structure, and it is characterized in that, comprise outer-hexagonal hook bolt and spanner, outer-hexagonal hook bolt has a through hole in nut place radial direction, and the two ends of through hole are with oblique chamfering; Spanner comprises the structures such as screw rod, handle, lock core, spring, baffle plate, screw; Described handle is made up of a stud and two nuts, and stud is through the through hole of screw rod one end, and formed with screw rod and be slidably connected, the two ends of stud are connected with nut respectively; The other end of described screw rod has interior hexangle type blind hole, has blind round hole in interior hexangle type blind hole sidewall symmetry position, has semi-cylindrical cascade notch and four tapped holes at screw rod bottom end face; Lock core comprises hemisphere type end cap and lock, and lock is semi-cylindrical thin plate, and end cap is hemisphere structure; One end of described spring penetrates in the blind round hole of screw rod, and supports this end face, and the other end supports the lock of lock core; Described lock core loads in the semi-cylindrical cascade notch of screw rod, and is formed between screw rod and be slidably connected; That to be gabarit be described cover plate is circular, the thin plate of Intermediate Gray hexangle type through hole, and in shape of through holes and screw rod, hexangle type blind hole is consistent, and has four unthreaded holes at the periphery of hexangle type through hole; Described screw is used for connecting screw rod and cover plate.
The invention has the beneficial effects as follows: one, Drop-proof of the present invention connects and can carry out adding work on existing bolt basis with its outer-hexagonal hook bolt of fastening structure and realize, and technique is simple, cost is low; Two, outer-hexagonal hook bolt to be removed is clamped by the lock core being provided with latch functions in screw rod fastening end with its spanner of fastening structure by Drop-proof connection of the present invention, effectively prevents the danger that bolt comes off after removal, improves the reliability of dismounting; Three, Drop-proof connection of the present invention only relies on Spring driving can complete the clamping treating demounting bolt with its spanner of fastening structure, and structure is simple, and does not need extra energy resource supply; Four, Drop-proof of the present invention connect with its spanner of fastening structure in use directly conveniently the working method of spanner use, locking mechanism by bolt clamping, improves the working efficiency of mounting or dismounting automatically; Five, Drop-proof connection of the present invention is not only applicable to the large complicated mechanical system such as aeroengine, numerical control machining center with fastening structure, also can be applicable to the situations such as the dismounting of civil works outdoor high-altitude link.

Embodiment
Below by specific embodiment, also the present invention is described in further detail by reference to the accompanying drawings.
Embodiment one: composition graphs 1, Fig. 2, Fig. 4 ~ Figure 10 illustrate the specific embodiment of the present invention, the supporting spanner 9 of mode of execution comprises screw rod 2, handle 10, lock core 5, spring 6, baffle plate 7, screw 8; Described handle 10 is made up of a stud 3 and two nuts 4, and stud 3 is through the through hole of screw rod 2 one end, and formed with screw rod 2 and be slidably connected, the two ends of stud 3 are connected with nut 4 respectively; The other end of described screw rod 2 has interior hexangle type blind hole, has blind round hole in interior hexangle type blind hole sidewall symmetry position, has semi-cylindrical cascade notch and four tapped holes at screw rod 2 bottom end face; Lock core 5 comprises hemisphere type end cap 11 and lock 12, and lock 12 is semi-cylindrical thin plate, and end cap 11 is hemisphere structure; One end of described spring 6 penetrates in the blind round hole of screw rod 2, and supports this end face, and the other end supports the lock 12 of lock core 5; Described lock core 5 loads in the semi-cylindrical cascade notch of screw rod 2, and is formed between screw rod 2 and be slidably connected; Described cover plate 7 for gabarit be circular, the thin plate of Intermediate Gray hexangle type through hole, in shape of through holes and screw rod 2, hexangle type blind hole is consistent, and has four unthreaded holes at the periphery of hexangle type through hole; Described screw 8 is for connecting screw rod 2 and cover plate 7.This outer-hexagonal hook bolt spanner 9 operationally, lock core 5 is first inner by the nut of outer-hexagonal hook bolt 1 press-in screw rod 2, time in the through hole that lock core 5 enters outer-hexagonal hook bolt 1, lock core 5 ejects by spring 6, now lock core 5 clamps outer-hexagonal hook bolt 1, and screw rod 2 normally unscrews outer-hexagonal hook bolt 1, when the screw thread of outer-hexagonal hook bolt 1 screws out completely from connected piece, regain spanner 9, outer-hexagonal hook bolt 1 takes out with spanner 9.
