Abstract
The utility model discloses one kind from corresponding air passenger chair framework packet mechanism for card, including packet card ontology and it is contained in Bao Kaben body and relative to its rotatable straight pin, the threaded hole being arranged concentrically with the counter sink of installation bolt is offered on straight pin, when pretension bolt, when the countersunk head hole site or angle of installing bolt change, by straight pin from the rotation under bolt pretightening, it is aligned bolt with screw thread axially bored line in straight pin always.The utility model proposes from corresponding air passenger chair framework packet mechanism for card, solve the problems, such as that packet card structure forms erection stress during the fastening process.
Description
Technical field
The utility model relates to aero seat technical field of structures, more particularly to it is a kind of from corresponding air passenger seat bone
Frame packet mechanism for card.
Background technique
Currently, well known packet mechanism for card is mainly utilized in packet card structure and is opened one at the cooperation circular hole of packet card structure
The opening or key type hole of reserved deformation process a threaded hole in one end of opening, and other end processing one is concentric with threaded hole
Counter sink.By tightening a bolt on counter sink side, clamped by tools for bolts ' pretension by packet card structure.
But tightening bolt simultaneously, as packet card structure is with by the deformation of packet card structure matching hole, cause threaded hole
It cannot be concentric between counter sink.And then when continuing pretension bolt, the change of bolt itself with bolt periphery connection structure will cause
Shape forms the stress of very large assembly, can produce bigger effect to the integral strength performance of air passenger seat.
Utility model content
The main purpose of the utility model is to provide one kind from corresponding air passenger chair framework packet mechanism for card, it is intended to
Solve the problems, such as that packet card structure forms erection stress during the fastening process.
To achieve the above object, the utility model provides a kind of from corresponding air passenger chair framework packet mechanism for card, packet
It includes packet card ontology and is contained in Bao Kaben body and relative to its rotatable straight pin, offered and installation spiral shell on straight pin
The threaded hole that the counter sink of bolt is arranged concentrically, when pretension bolt, when the countersunk head hole site or angle of installing bolt change,
By straight pin from the rotation under bolt pretightening, it is aligned bolt with screw thread axially bored line in straight pin always.
Preferably, the axis of the straight pin is vertically arranged with the axis of its threaded hole.
Preferably, the length of the straight pin is less than the thickness of packet card ontology.
Preferably, the straight pin is equipped with flat recess or cross recess for carrying out angular adjustment in initial installation.
Preferably, the both ends of the straight pin are equipped with flat recess or cross recess.
The utility model proposes from corresponding air passenger chair framework packet mechanism for card, by being arranged on packet card ontology
One straight pin can eliminate the extrusion deformation stress of bolt and packet card structure in assembling process；Make packet card structure in same bolt
Under the requirement of pre-fastening moment, it ensure that the consistency of armchair structure strength character, structure are simple and very easy to use.
Detailed description of the invention
Fig. 1 is sectional structural map of the utility model from corresponding air passenger chair framework packet mechanism for card；
Fig. 2 is axonometric drawing of the utility model from corresponding air passenger chair framework packet mechanism for card.
In figure, 1. packet card ontologies, 2. straight pins, 3. bolts, 4. by packet card structure.
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this
Utility model.
It should be noted that in the description of the present invention, term " transverse direction ", " longitudinal direction ", "upper", "lower", " preceding ",
The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on
Orientation or positional relationship shown in the drawings, is merely for convenience of describing the present invention and simplifying the description, and is not instruction or dark
Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair
The limitation of the utility model.
Referring to Figures 1 and 2, a kind of from corresponding air passenger chair framework packet mechanism for card in this preferred embodiment, including
It packet card ontology 1 and is contained in packet card ontology 1 and relative to its rotatable straight pin 2, offers and install on straight pin 2
The threaded hole that the counter sink of bolt 3 is arranged concentrically, when pretension bolt 3, when the countersunk head hole site of installation bolt 3 or angle become
When change, by straight pin 2 from rotation under bolt pretightening, make bolt 3 always with screw thread axially bored line pair in straight pin 2
Together.
Specifically, the axis of straight pin 2 is vertically arranged with the axis of its threaded hole.The length of straight pin 2 is less than Bao Kaben
The thickness of body 1, in this way, both ends do not protrude from 1 outside of packet card ontology, to keep away when straight pin 2 is installed on packet card ontology 1
Exempt from the assembly for interfering other parts.
Further, straight pin 2 is equipped with flat recess or cross recess for carrying out angular adjustment in initial installation.It is excellent
The both ends of straight pin 2 are selected to be equipped with flat recess or cross recess.It is inserted into flat recess or cross recess by tool, so as to adjust straight pin
2 setting angle.
When pretension bolt 3, even if the borehole structure of packet card chair pipe has deformation, cause on packet card structure for installing bolt 3
Hole position or angle change, bolt 3 can be made always by straight pin 2 from rotation under 3 pretightning force of bolt
With the screw thread axially bored line of straight pin 2 to upper, the extrusion deformation stress for generating bolt and its peripheral structure in assembling process is avoided.
The utility model proposes from corresponding air passenger chair framework packet mechanism for card, by being set on packet card ontology 1
A straight pin 2 is set, the extrusion deformation stress of bolt and packet card structure in assembling process can be eliminated；Make packet card structure in same spiral shell
Under the requirement of bolt pre-fastening moment, it ensure that the consistency of armchair structure strength character, structure are simple and very easy to use.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure transformation made based on the specification and figures of the utility model, it is relevant to be applied directly or indirectly in other
Technical field is also included in the patent protection scope of the utility model.
