Abstract
The invention discloses a spreading lock for building connection of 4.3 notch profiles in a commodity fair or a store structure assembly system. The spreading lock comprises a supporting lock body A, a supporting lock body B, an ejection piece for spreading the supporting lock bodies and an elastic pin for spreading a rear supporting lock piece to restore; and the rear ends of the supporting lock body A and the supporting lock body B are hinged, the front ends of the supporting lock body A and the supporting lock body B are provided with bolts at mutually staggered corresponding positions respectively, one supporting lock body is provided with a screw hole matched with the ejection piece, and the bolts on the two supporting lock bodies are opened and closed due to the rotation of the ejection piece arranged in the screw hole. The design of the lock is simplified, and the strength of the lock is furthest improved.
Description
Technical field
The invention belongs in the building structure especially for the connection latch fitting in trade fair or the shop structure assembly system, specifically is a kind ofly to be used for other 4.3 notch in the system of being linked and packed and to support the lockset of section bar or build-up member.
Background technique
In 4.3 original notch display and demonstration systems, Placement adopts the elastic spring lock, because the elastic spring lock comprises lock housing, reed and eccentric wheel, its lock housing and reed are divided into inside and outside two-layer, not only make complicated, the assembling trouble, and when applying to the sulculus mouth, this design meeting further reduces the intensity of reed, thereby causes the decline of join strength; Also there is a shortcoming in present elastic spring lock, can only be applicable to that exactly 90 degree directions connect, require increasing today for personalization, just the Placement of 90 degree has narrow limitation in a lot of display and demonstration structures, according to the moulding needs, requirement has many oblique connections in 4.3 notch display and demonstration systems, depend the requirement that mechanical connection can not satisfy the exhibition fast assembling-disassembling alone.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, provides a kind of easily manufactured, can be directly with building structure in other 4.3 notch section bar or build-up member realize the lockset that struts that is connected.
For addressing the above problem, the present invention adopts following technology: a kind of lockset that struts, be used for building the connection of trade fair or shop structure assembly system 4.3 notch section bars, comprise and support lock body A, support lock body B, be used to strut the top bracing member that supports lock body and be used to strut the back and support the resilient key that latch fitting is replied usefulness; Described support lock body A, it is hinged to support lock body B rear end, front end is respectively equipped with the dead bolt that corresponding position staggers mutually, and described one supports lock body is provided with the screw that matches with top bracing member, and the dead bolt on the described two support lock bodies is because of being arranged on the rotation folding of the top bracing member in the screw.
The present invention has overcome the narrow limitation of elasticity Reed lock in original 4.3 notch display and demonstration systems, by small and exquisite, design flexible, dead bolt is set directly on the lock housing, under the situation that guarantees join strength, will make simplification, the cost reductionization like this, and realized making the oblique connection of multi-angle easier for installation, quick.
As a further improvement on the present invention, under lockset closed up state, described two dead bolts that support on the lock body were arranged side by side on the same straight line, and it is convenient to peg graft when cooperating with the section bar notch like this, and can promote the thickness of dead bolt to the full extent, thereby strengthen the intensity that lockset connects.
The dead bolt that supports latch fitting described in the present invention is provided with the groove that matches with the profile wall of connection profile notch both sides.By the matching relationship of groove and profile wall, realize that both closely connect.
As the preferred embodiments of the present invention, and can increase join strength: described one supports latch fitting is provided with two dead bolts, and another supports latch fitting and is provided with a dead bolt and this dead bolt between other two dead bolts.
The present invention struts the lock working principle: top bracing member is shored to open by rotation and is supported lock body A and support lock body B, supports lock body A and supports lock body B then by friction interlock master 4.3 notches, supports lock body A simultaneously and support lock body B that resilient key is formed compression; Unclamp top bracing member, support lock body A and support lock body B be closed to together by resilient key effect resilience, from 4.3 notches, deviate from.
The present invention has simplified the design of lockset, and has improved the intensity of lockset to the full extent.
Description of drawings
Fig. 1 is locked in the structural drawing of closed state for the present invention struts;
Fig. 2 is locked in the structural drawing of softened state for the present invention struts;
Fig. 3 is a docking structure perspective view of the present invention.
Among the figure: 1 for supporting lock body A; 2 for supporting lock body B; 3 is top bracing member; 4 is resilient key; 5 is connection profile; 6 is groove; 7 is dead bolt.
Embodiment
The present invention is further described below in conjunction with accompanying drawing and embodiment.
Embodiment 1: as Fig. 1, shown in 2: the present invention relates to a kind of lockset that struts, be used for building the connection of trade fair or shop structure assembly system 4.3 notch section bars, comprise and support lock body A, support lock body B, be used to strut two and support the top bracing member 3 of lock body and be used for the resilient keys 4 that lockset struts the answer of back two support latch fittings; The front side of described support lock body B is provided with a screw, and top bracing member 3 links to each other with the screw screw thread; Supporting the tail end of lock body, supporting lock body A and form that a curve bath is coated on the outside of supporting lock body B and both form hinging structure, and resilient key 4 as hinging shaft respectively with support lock body A and support lock body B intrados and closely contact; Be provided with two dead bolts 7 at the front end that supports lock body A, and lay respectively at the both sides of front end; And the front end that supports lock body B is provided with a dead bolt 7, and is positioned at the neutral position of front end; As shown in Figure 1: when strutting the lockset merging, three dead bolts 7 that stagger mutually in the position are arranged side by side on the medial axis of lockset; As Fig. 2, shown in Figure 3: be formed with the groove 6 that matches with the profile wall of connection profile notch both sides in the outside of dead bolt; When mounted, strut the notch that lockset dead bolt 7 under closed state stretches into connection profile 5, the back struts two by rotation top bracing member 3 and supports lock bodies, profile wall is embedded in the groove 6 of dead bolt realize that strutting lockset is connected with the locking of connection profile 5.
