Abstract

The utility model relates to a handle limit-type door lock, belongs to hardware door locks, and is designed for aiming at the technical problems that the prior similar door lock product has a poor structural design. The door lock comprises a lock catch, a handle, a base, a rotating shaft, a steel pin and a lock housing, wherein, the handle is connected with the rotating shaft through an elastic cotter pin, and drives the rotating shaft to rotate; the lock housing and the base are fixed into a whole through second combined screws; and the steel pin is fixed on the rotating shaft through first combined screws. The design points of the utility model lie in that nuts are arranged in the lock catch, the screws are connected with the nuts; the lock catch is fixed on the base; the rotating shaft is sleeved in the base and the lock housing; a gasket and a tightened gear ring are arranged at the joint between the rotating shaft and the lock housing; the tightened gear ring is buckled with a second groove formed on the outer diameter of the rotating shaft; a second seal ring is arranged in a first groove; and the tightened gear ring is buckled with the second groove of the rotating shaft. The door lock has the advantages of reliable design, simple structure, high yield and convenient assembly during producing process, and is suitable for various electrical bins and similar products.

Description

The limit-type door lock of handle

Technical field

The utility model relates to the five metals door lock, is a kind of limit-type door lock of handle.

Background technology

At present, the product and the kind of door lock are a lot, can be divided into kinds such as door and window lock, electronic lock, lock, furniture lock, padlock according to its purposes.Wherein, the snap close of some door locks is installed and need be fixed on the pedestal with riveted way, and this assembling mode efficient is lower, and the snap close of riveted joint is insecure, easily the rivet surfacing is destroyed during riveted joint to cause yield rate lower.And the handle of other door locks is pressed in the process of rotation, and the rotating shaft meeting moves up and down, because handle surface and seat surface are not plane contact, causes the lacquer of hadle base-plates surface to be wiped off easily, and entire product is scrapped.

Summary of the invention

For overcoming the deficiency of above-mentioned existence, the utility model purpose is the limit-type door lock of a kind of handle that provides to this area, makes it solve the existing not good enough technical problem of similar door lock product structure design.The purpose of this utility model is achieved through the following technical solutions.

The limit-type door lock of a kind of handle, this door lock comprises snap close, handle, pedestal, rotating shaft, steel bolt, lock housing, described handle is hinged by elastic opening pin and rotating shaft, handle drives the rotating shaft rotation, lock housing and pedestal are fixed as one by second screw assemblies, and the steel bolt is fixed in rotating shaft by first screw assemblies.Its design main points are to be provided with nut in the described snap close, and screw is connected with nut, and snap close is fixed in pedestal.Nut in screw and the snap close screws, and snap close can be fixed in pedestal, and this assembling mode is simple, convenient, and operating efficiency and yield rate are higher.Pedestal and lock housing are inserted in rotating shaft, and rotating shaft and pedestal junction are provided with first sealing ring, and rotating shaft and lock housing junction are provided with pad, tighten up gear ring, and second groove that tightens up gear ring and rotating shaft external diameter interlocks.Handle surface contacts with base plane in the handle rotary course, and handle is subjected to downforce and tightens up the tightening force interaction of gear ring, and rotating shaft can not move up and down, and handle promptly can not wiped the lacquer of base-plates surface off.

The external diameter of described rotating shaft is provided with first groove and second groove, and first groove of rotating shaft and pedestal junction is provided with first sealing ring.The anti-sealing of first sealing ring enters lock housing outside pedestal, influence the operate as normal of component in the lock housing.

Described screw and pedestal junction are provided with second sealing ring.The anti-sealing of second sealing ring enters pedestal, makes being connected of snap close and pedestal more firm simultaneously.

The utility model reasonable in design, simple in structure, easy to assembly in process of production, the yield rate height is applicable to that various electric bins and like product are supporting.

The specific embodiment

Embodiment is with assembling of the present utility model and use and be example.As shown in Figure 1, upper and lower tooth bar is connected with lock housing 14 inner associated components, other component lock housing of packing into screws second screw assemblies 13 in the lock housing, and lock housing and pedestal 6 are connected as a single entity.Rotating shaft 7 is connected with handle 4, and first sealing ring 8 is inserted in first groove 701 of rotating shaft external diameter, and pedestal and lock housing are inserted in rotating shaft successively, hear the sound of " bumping ", second groove 702 of rotating shaft external diameter with tighten up gear ring 10 and interlock.Steel bolt 12 is inserted in rotating shaft, screws first screw assemblies 11, and the steel bolt is fixed in rotating shaft.Screw 2 is inserted in second sealing ring 15 and the pedestal successively, and screws with nut in the snap close 1, and snap close is fixed on the pedestal, and the utility model can assemble and finish

As Fig. 5, shown in Figure 7, turning handle, handle drives rotating shafts by elastic opening pin 5 and rotates, and rotating shaft is stressed when moving down, and the tightening force effect that is subjected to tightening up gear ring, rotating shaft are under pressure and the acting in conjunction of tightening force, do not move up and down.Handle contacts with base plane in 5 °～90 ° rotary course, and handle and base-plates surface do not bump.
