Abstract
The utility model discloses a light -duty lock for mutual connection between the various cupboard section bars of trough of belt mouth, including an elasticity reed and a locking screw, the elasticity reed divide into reed section, lower reed section and arc linkage segment, going up reed and the rear end of reed down and passing through the arc linkage segment and connect and form one wholly, and the front end is equipped with the spring bolt respectively, be equipped with the screw with locking screw matched with under or on the reed at last reed, the spring bolt of going up reed section, lower reed section struts or folds because of the locking screw rotation that sets up in the screw. The utility model discloses simple structure has saved lock housing part, the price economy, the utility model is simple in operation, only spanner of need can.
Description
Technical field
The utility model belongs to especially for the connection lock element in trade fair or shop structure assembling system in building structure, specifically a kind of for connection mutual between the various cupboard section bars with notch.
Background technique
In original display and demonstration system, section bar notch Placement adopts elastic spring lock, because 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 manufacture complexity, assembling trouble, and when applying to small-rabbet, this design can reduce the intensity of reed further, thus causes the decline of join strength; Also there is a shortcoming in present elastic spring lock, 90 degree of directions can only be applicable to exactly connect, for individual requirement increasing today, just the Placement of 90 degree has narrow limitation in a lot of display and demonstration structure, according to moulding needs, require there are many oblique connections in notch display and demonstration system, depend the requirement that mechanical connection can not meet exhibition fast assembling-disassembling alone.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of structure simple, easily manufactured, directly can realize the light-duty lock of quick assembling with the various cupboard section bars of band notch.
For solving the problem, the utility model adopts following technology:
A kind of light-duty lock, for building the connection of trade fair or shop structure assembling system medium section, comprise an elastic spring and lock screw, described elastic spring is divided into upper reed plate section, lower reed section and arc linkage section; The rear end of described upper reed plate and lower reed is connected to form one overall by arc linkage section, the front end of described upper reed plate section and lower reed section is respectively equipped with dead bolt, and under lockset releasing orientation, and upper and lower reed section front end dead bolt strikes a bargain wrong closed configuration; Upper reed plate or lower reed are provided with the screw matched with lock screw, and the dead bolt of described upper reed plate section, lower reed section struts because the lock screw be arranged in screw rotates or closes up.
Further improvement of the utility model is: described arc linkage section is formed with gap, makes installation lighter, quick.
Further improvement of the utility model is: described screw on upper reed plate or lower reed is formed with thread section, makes lockset connect more reliable, safety.
The lockset that the utility model relates to only is provided with reed and lock screw two parts, farthest simplify the structure of lockset, design small and exquisite, flexibly, and when assembling, lockset with reed and lock screw two parts for lock core, section bar is lock housing, is combined to form integrative-structure, not only eliminates lock housing part, save cost, and sound construction, reliable.
The working principle of this light-duty lock is: lock screw is by the upper and lower reed of rotary opening, and namely the notch that upper and lower reed then hooks section bar by the dead bolt of front end completes the process of locking, simple to operate, quick.
Accompanying drawing explanation
Fig. 1 is the light-duty structural drawing being locked in releasing orientation of the utility model;
Fig. 2 is the light-duty structural drawing being locked in locking state of the utility model;
Fig. 3 is docking structure perspective view of the present utility model.
In figure: 1 is elastic spring; 11 is upper reed plate section; 12 is lower reed section; 13 is arc linkage section; 14 is dead bolt; 15 is gap; 2 is lock screw; 3 is screw; 31 is thread section; 4 is section bar.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Embodiment 1: as shown in Figure 1, 2: the utility model relates to a kind of light-duty lock, for connection mutual between the various cupboard section bars with notch, comprises an elastic spring 1 and lock screw 2; Described elastic spring 1 is divided into upper reed plate section 11, lower reed section 12 and arc linkage section 13; " U " type structure that the rear end of described upper reed plate section 11 and lower reed section 12 is connected to form one by arc linkage section 13, is provided with a dead bolt, and is positioned at the neutral position of front end in the front end of upper reed plate section 11; Be provided with two dead bolts in the front end of lower reed section 12, and lay respectively at the both sides of front end; As shown in figs. 1 and 3: under lockset releasing orientation, the dead bolt 14 that upper and lower reed section front end is formed strikes a bargain wrong closed configuration, is arranged side by side on the medial axis of lockset.Be provided with a screw 3 in the front side of upper reed plate section, screw 3 is formed with thread section 31, and lock screw 2 is connected with screw section 31 screw thread.
As illustrated in fig. 1 and 2: be formed with the hook groove matched with the profile wall of connection profile notch both sides in the outside of dead bolt; As shown in Figure 2, when the locking of light-duty lock, dead bolt 14 stretches into the notch of connection profile 4, after strut upper and lower reed section by rotational lock screw 2, profile wall is embedded in the hook groove of dead bolt, realize light-duty lock to be connected with the locking of connection profile.
The utility model structure is simple, and eliminate lock housing part, price economy, the cost of whole lock can be controlled in about one yuan; The utility model is simple to operate, only needs one spanner.The utility model is through scientific and reasonable mechanical analysis, and the pull test value of lock reaches 2.4KN and reed without obvious destruction, is enough to meet the connection request being used in cupboard class part.
Claims (3)
1. a light-duty lock, for building the connection of trade fair or shop structure assembling system medium section, is characterized in that: comprise an elastic spring and lock screw, described elastic spring is divided into upper reed plate section, lower reed section and arc linkage section; The rear end of described upper reed plate and lower reed is connected to form one overall by arc linkage section, the front end of described upper reed plate section and lower reed section is respectively equipped with dead bolt, and under lockset releasing orientation, and upper and lower reed section front end dead bolt strikes a bargain wrong closed configuration; Upper reed plate or lower reed are provided with the screw matched with lock screw, and the dead bolt of described upper reed plate section, lower reed section struts because the lock screw be arranged in screw rotates or closes up.
