Abstract

The utility model relates to a three-clamping lock which comprises a lock case, a three-clamping reed and an eccentric wheel. The three-clamping reed is arranged in the lock case, a hole matched with the eccentric wheel is formed in the three-clamping reed, and the three-clamping reed moves forward and backward through the rotation of the eccentric wheel arranged in the hole. The lock case is formed by stamping a seamless steel tube with the rectangular section, a rear cover is arranged at the rear end of the lock case, and a lower support used for supporting the rear end of the three-clamping reed is arranged on the inner side of the rear cover. The three-clamping lock prevents a lock head from loosening due to increasing of manual torsion, and greatly improves the capacity of a lateral stopping position; meanwhile, the manufacturing cost is greatly reduced, and matching between the reed and the eccentric wheel can be more stable and effective.

Description

A kind of three kaysers

Technical field

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

Background technique

Along with social development, a large amount of section bars are used to the fields such as enterprises propagandist, exhibition articles for use, and light because of himself, it is convenient to dismantle, and is more and more subject to liking of people.Now for building structure, especially for the lockset in trade fair or shop structure assembling system, generally comprise lock housing, reed and eccentric wheel, lock housing is formed by upper and lower two section bar riveteds, front portion is provided with reed guide ledges, rear portion is provided with eccentric wheel and reed boss, on reed, be provided with the mounting hole coordinating with eccentric wheel, in order to guarantee eccentric wheel, be with stably movable contact spring work, the upper and lower two ends of described eccentric wheel form respectively projection, and upper and lower support snaps in the hole forming in lock housing upper and lower side.The shortcoming that above-mentioned lockset exists: 1, lock housing is that two riveteds form easily makes tapered end scatter after manual torsion strengthens, and not so damages lockset and in building connection, has potential safety hazard.2, manufacturing structure, technique are quite complicated, for eccentric location, adopt two location, axle center, hole, must on the upper and lower side plate of lock housing, punch, and eccentric wheel lower end must form very long projection, and cost is high; 3, simultaneously owing to being subject to the restriction of size and Self-locking angle, boss etc., easily produce locking phenomenon, affect the quick handling of lockset.The defects such as 4, reed, eccentric combination exist and regulate gap ability, and join strength is little.

Summary of the invention

For overcoming above-mentioned defect, it is a kind of simple in structure, stable that the purpose of this utility model is to provide, and three kaysers that resistance to compression and bearing capacity are strong, have avoided manual torsion to add the phenomenon that roughly tapered end unclamps, and have greatly improved the ability of side stop bit, and beautiful shape.

For achieving the above object, the utility model provides technological scheme to be:

A kind of three kaysers, for the support and connection of building trade fair or shop structure assembling system, comprise lock housing, three Clip Reeds and eccentric wheel, described three Clip Reeds are placed in lock housing, on three Clip Reeds, be provided with the hole of matching with eccentric wheel, described three Clip Reeds seesaw by the eccentric wheel rotation being arranged in hole, the seamless steel pipe that described lock housing is rectangle by cross section is stamped to form, rear end in lock housing is provided with bonnet, and described bonnet inner side is provided with for supporting the lower support of three Clip Reed rear ends.

As preferred embodiment of the present utility model: described bonnet is independent component, above its lower support, be provided with upper support, the top edge of described upper support, the lower limb of lower support and lock-shell lining drive fit are formed with the gap for three Clip Reed activities between upper and lower support.

As another preferred embodiment of the present utility model: described bonnet is bent to form by both sides side plate and the top plate of lock housing rear end; The lower support of described bonnet is formed by the side plate bending, and between the side plate upper edge of described two lateral bucklings and lock housing top plate, is formed with the gap for three Clip Reed activities.

As the 3rd preferred embodiment of the present utility model: described bonnet is once bent to form by top plate or lower panel, the lower support on described bonnet is the independent component that is fixed on bonnet inner side.

Further improvement of the utility model is: the front end of described lower support is formed with downward-sloping inclined-plane, and the rear end of described three Clip Reeds is formed with the chamfering matching with lower support inclined-plane.Like this, in locking, three Clip Reed inclined-planes are climbing backward upwards, with eccentric wheel, be rotated further and make the tail end of three Clip Reeds continue to move to backward in gap again, thereby make eccentric wheel realize plane positioning, avoided the stuck phenomenon of lockset to make eccentric lower end be supported simultaneously, thus stable operation

Further improvement of the utility model is: described eccentric wheel comprises the eccentric mass of lower end and the cylinder of upper end, described eccentric wheel is connected by the eccentric mass of lower end and the hole of three Clip Reeds, on the top plate of described lock housing, have mounting hole, described eccentric wheel is connected by the cylinder of upper end and the mounting hole of lock housing.Because eccentric lower end has been realized support and connection by the afterbody of three Clip Reeds with coordinating of lower support, thus reduced original eccentric wheel adopt 2 axle center, hole whens location must lower support, structure is more simplified.

Due to lock housing use is seamless steel pipe material, the lock housing technique of manufacturing three as related in the patent No. 200710024653 Clip Reed structures of installation is more loaded down with trivial details, in order to simplify lock housing processing technology, the utility model improves on original three Clip Reed architecture basics: at the middle part of three dead bolts of three Clip Reeds, middle dead bolt and both sides dead bolt are respectively by being bent to form projection up and down; Corresponding to the rear position of dead bolt projection, on the top plate of lock housing and lower panel, by punching press, form three oblique bearing surfaces, the front end of described three oblique bearing surfaces acts on respectively the protruding ramp of three dead bolts.

It is basis that the utility model lock housing has adopted the seamless steel pipe of integral type, intensity and the fastness of whole lock housing have effectively been guaranteed, because adopting punching press, it forms simultaneously, lock housing manufacture is simplified, high-speeding, has reduced cost of production, has simplified eccentric lower convex platform simultaneously, reduced materials, provided cost savings; The utility model has also been simplified lock housing, and the matching relationship between reed and eccentric wheel has been avoided the generation of stuck phenomenon, has improved working efficiency.And owing to being provided with bonnet, not only profile is more attractive in appearance, and has avoided pin to enter lockset internal structure and occurred the phenomenons such as stuck.
