Abstract
The utility model relates to the technical field of the connecting device, in particular to the improved structure of the connecting rod with the accurate sleeve jointing and the firmness. The utility model mode comprises an inserting rod and a sleeving rod. A center tap which is composed of the connecting part of the inserting part and the connecting part of the sleeving rod is provided between the inserting rod and the sleeving rod. The external wall of the connecting part of the inserting rod is formed with a limiting slot which is bent. The radial part of the limiting slot is provided with a limiting hole, and a contacting and clamping ring which is matched with a pushing and contacting limiting hole is arranged in the connecting part of the inserting rod. A raised part which is corresponded with the limiting slot is formed in the connecting part of the sleeving rod. The center tap is respectively connected with the inserting rod and the sleeving rod by the screw thread. The effects of the accurate sleeve jointing, the firmness and the high stability of the connecting rod can be obtained through the technical project. The connecting rod adopting the mechanism has tight sleeve jointing and minimal gap.
Description
Technical field:
The utility model relates to the connection set technical field, refers in particular to the structure-improved of accurate, the firm connecting rod of a kind of socket.
Background technique:
Known, in life many times because to the requirement of the length of article, two component need be carried out socket, and requirement will have very high accuracy and soundness, but this series products in the market all is difficult to the purpose that reaches such, commonplace in the prior art application and using effect connecting rod are preferably seen accompanying drawing 1, this connecting rod comprises loop bar 01 and inserted link 02, form the restraining groove 021 of bending in an end of inserted link 02, in the inwall of loop bar 01 shaft form with inserted link 02 on restraining groove 021 mutual corresponding lug boss 011, during use, axial cell body socket with the lug boss 011 corresponding inserted link 02 of loop bar 01, this lug boss 011 props up the end of restraining groove 021 axial cell body after loop bar 01 is inserted in inserted link 02 enough degree of depth, rotates inserted link 02 then or loop bar 01 is fixedly sleeved with both.Though this structure of connecting rod has tangible progress than traditional direct sleeve mode, and can realize the socket of inserted link 02 and loop bar 01 preferably, but because restraining groove 021 and lug boss 011 easily slide for flexibly connecting, so its validity and soundness are all not enough.
Summary of the invention:
The utility model purpose is to provide the structure-improved of the little connecting rod in accurate, firm, the stable height of a kind of socket, cover and slit.
For achieving the above object, the technical solution of the utility model is: it comprises inserted link and loop bar, is provided with middle joint between inserted link and the loop bar, and middle joint is made up of inserted link joint and loop bar joint.
Described inserted link joint outer wall forms the restraining groove of bending, this restraining groove radial component has spacing hole, be provided with to snap ring in inserted link joint inside, should support snap ring and cooperate the contact spacing hole, described loop bar joint inside forms the lug boss corresponding with restraining groove.
Joint and inserted link and loop bar are respectively by being threaded among described.
The socket that can reach connecting rod by above technological scheme accurately, firmly, effect that stability is high, and adopt the connecting rod of this kind mechanism because its socket is tight, the slit is minimum, so quality and class are all higher.
Description of drawings:
Fig. 1 is that the structure of the connecting rod of prior art splits schematic representation;
Fig. 2 is that the structure of the utility model inserted link joint splits schematic representation;
Fig. 3 is the not preceding user mode figure of sleeve of the utility model inserted link joint and loop bar joint;
Fig. 4 is that the structure of the utility model splits schematic representation;
Fig. 5 is the structural representation of the utility model.
Embodiment:
See accompanying drawing 2～Fig. 5, the utility model comprises inserted link 1 and loop bar 2, is provided with middle joint 3 between inserted link 1 and the loop bar 2, and middle joint 3 is made up of inserted link joint 31 and loop bar joint 32.Wherein by being threadedly connected in inserted link 1 and the loop bar 2, this kind Placement is convenient to fractionation, the assembling between middle joint 3 and inserted link 1 and the loop bar 2 respectively for inserted link joint 31 and loop bar joint 32.Can certainly with other modes just middle joint 3 be fixedly connected in inserted link 1 and the loop bar 2.
Described inserted link joint 31 outer walls form the restraining groove 311 of bending, these restraining groove 311 axial components are used for inserted link 1 and vertically go deep into loop bar 2, radial component is used for fixing spacing, radially partly have spacing hole 312 in the restraining groove 311, be provided with to snap ring 313 in inserted link joint 31 inside, should support snap ring 313 and cooperate contact spacing hole 312.Loop bar joint 32 inside form the lug boss 321 corresponding with restraining groove 311.Should support snap ring 313 a part of snap rings and stretch out by spacing hole 312, when the connecting rod cover and the time, the lug boss 321 of this part and inserted link joint 31 contacts.
When making connecting rod, earlier will to snap ring 313 pack into inserted link joint 31 and make it a part stretch out outside the hole by spacing hole 312, then that inserted link joint 31 is embedded and be fixed on inserted link 1 one ends, equally that loop bar joint 32 is embedded and be fixed on the corresponding end of loop bar 2 and inserted link 1.
During use, the lug boss 321 of the corresponding loop bar 2 of the restraining groove of inserted link 1 is inwardly inserted, when the degree of depth that is inserted into requirement, inserted link 1 is laterally rotated, at this moment, support the lug boss 321 that position that snap ring 313 stretches out spacing hole 312 can contact loop bar 2, but make for deformation metal or other materials owing to support snap ring 313, therefore support restoring to the original state after snap ring 313 is crossed this lug boss, snap ring 313 usefulness metals are made and connecting rod inside is cavity if support at once, will hear very clearly that inserted link 1 of " click " and loop bar 2 finish sleeve, if in the time of need tearing the two open, need firmly rotate inserted link 1 or loop bar 2, hear " click " one after, can extract inserted link 1 or loop bar 2.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
