Abstract

The invention relates to a connecting lockset which comprises a lock shell, a reed and an eccentric wheel. The lock shell is internally provided with at least one containing cavity which is directly provided with the reed so as to connect other supporting proximate matters or assembly parts in an assembly system; two sides of the lock shell are respectively provided with side wings in integral structures; the lockset is inserted in a lead rail facing to the inside of the supporting proximate matters through the side wings; the lead rail is provided with through holes for inserting fixing members which fix the lockset on the lead rail along the axial direction; a mounting hole matched with the eccentric wheel is arranged on the reed; the reed moves forwards and backwards through the rotation of the eccentric wheel arranged in the mounting hole; a lug boss for supporting the reed is also arranged on the lock shell; and the eccentric wheel is directly assembled at a gap at the rear part of the lock shell and positioned through the matching of the mounting hole. The invention has the advantage of providing the connecting lockset which is convenient to manufacture and can be directly connected with the supporting proximate matter or the assembly parts in a constructed structure.

Description

A kind of connection lockset

Technical field

The present invention relates to be used for building structure especially for the link in trade fair or the shop structure assembly system, specifically be a kind of be used for connecting and the support assemblies system in other supports the lockset of section bar or build-up member.

Background technique

Existing three clip spring lock comprises the lock shell; Reed and eccentric wheel; The lock shell is whole hollow-core construction, and the front portion is provided with the reed guide ledges, and the rear portion is provided with eccentric wheel and reed boss; Reed is provided with the mounting hole that cooperates with eccentric wheel, and reed seesaws through the eccentric rotation that is arranged in the mounting hole; So when apply to building structure especially for trade fair or shop structure assembly system in the time; It must could be realized by means of an ABAP Adapter when section bar was connected supporting with other; Like the patent No. is to disclose above-mentioned Placement among the ZL99111845.6; The manufacturing of its lockset and ABAP Adapter all must accurately cooperate, and makes complicacy, the assembling trouble; Being connected then by means of eccentric wheel between lockset and the ABAP Adapter, so in the ABAP Adapter that manufacturing matches, the design and the manufacturing of lockset are had higher requirement, eccentric wheel must form can be by the formula structure, presses during installation to place in the lock shell, then ejects; The complicacy of also bringing simultaneously reed, eccentric wheel and lock shell to make; And locking perforate on the shell, can cause locking the decline of shell intensity; Simultaneously, make eccentric wheel, influence the quick loading and unloading of lockset by not going down owing to receive size and, be easy to generate locking phenomenon from the restriction of the locking angle.

Summary of the invention

Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, provides a kind of easily manufactured, can be directly with building structure in the connection lockset that is connected of support section bar or build-up member realization.

For addressing the above problem; The present invention adopts following technology: a kind of connection lockset; Be used for building the support and connection of trade fair or shop structure assembly system, it comprises the lock shell, reed and eccentric wheel; Be provided with at least one directly cavity volume of assembling reed in the said lock shell, so as to other support section bar or the build-up member in the system of being linked and packed; Said lock shell both sides are respectively equipped with the flank into a single integrated structure with it; Said lockset is plugged on towards supporting on the inner guide rail of section bar through flank; Guide rail has the through hole of the fixed block that is used to plant; According to being axially fixed on the guide rail, said reed is provided with the mounting hole that cooperates with eccentric wheel to these fixed blocks with lockset, and reed seesaws through the eccentric rotation that is arranged in the mounting hole; On the lock shell, also be provided with the boss of supporting spring, said eccentric wheel cooperates the location directly to be assemblied in the opening position at lock shell rear portion through mounting hole.

The present invention has abandoned installation, the mentality of designing of original ABAP Adapter and lockset combination, and both function is incorporated into one, can directly lockset be plugged on the guide rail that supports section bar inside; The back is fixed in the inner of this support section bar through fixed block; Realize supporting being connected between section bar through reed simultaneously, and because lockset itself serves as this role of ABAP Adapter, need not eccentric wheel be designed to can be by the formula structure with other; Need not consider the structural type of reed and boss; Simplify the design of above-mentioned part, also so avoided perforate on the lock shell, improved the intensity of lockset simultaneously.Like this, not only need not consider the height matching relationship between lockset and the ABAP Adapter, will make simplification, cost reduces, and makes easier for installation, quick.

As further improvement of the present invention, at least two stiffening ribs are set on the said flank, guarantee the support strength of lockset.

As the preferred embodiments of the present invention: be furnished with tapped hole on the flank of said lockset, the connection of the screw that is used for using as fixed block, said tapped hole can be securely fixed in lockset on the guide rail that supports section bar through screw being positioned at reinforcing rib design.

Lockset becomes platy structure described in the present invention, is formed with on two flanks of said lockset and the corresponding track of guide rail, through matching relationship between the two, realizes accurate location between the two, promotes the rapid of installation.

As further improvement of the present invention, the lock shell front end of said lockset is provided with positioning tab, when docking with other section bars, can utilize positioning tab to insert in the notch of this section bar earlier, behind the location, locks connection again, and is convenient, fast.

As further improvement of the present invention, said eccentric wheel is provided with the conical cambered surface that the guiding manipulate tools imports, the quick contraposition of notch on guiding manipulate tools and the eccentric wheel.
