Abstract

Disclosed is an improved construction of bathroom door lock which is suitable of long time use in damp environment, which is characterized of that an axle core is vertically inserted into a solid plate. The centre of the axle core is covered with a fan shape gear and a rack which is meshed with the fan shape gear. The rack is inserted in the one side of the inner cavity of the lock bolt. The lock bolt is arranged in the shape cavity of the outer casing. The rear end of the lock bolt is provided with a spring and a spring socket to press the lock bolt head to project out of the casing. The lock casing and the solid plate are fixed together by cup-head bolt. A pressing board which is corresponded with the other face of the solid plate and a pad is used for clamping on the pre-opened hole position of the glass door plate by resultant force and is connecting fixed by headless bolt and conical nut. Two handles are respectively arranged at the two ends of the axle core which are projected out of the lock body. When operating, the handle is rotated by hand to control expansion and contraction of the lock bolt to achieve the goal of opening or closing the door.

Description

Structure improved bathroom door lock

Technical field

The utility model relates to a kind of bathroom door lock in the architectural hardware field, refers to the structure improved bathroom door lock that a kind of adaptation can normally be used under the wet environment condition especially.

Background technology

In modern architecture, just applying glass door as indoor a kind of luxurious decoration baffle, have as protective door, as access door, shower door etc.On these glass doors except that common adapted metal hinge being connected the hinge as door and wall, also must open the door as manipulation or handle at closing time by the adapted door handles of metal, what have also will install Door lock made of metal additional to implement the locking and the control of door, because being installed in metal latch on the shower door must be in moist ambient conditions for a long time and work, and the clamping stagnation that at present general door lock is unblanked because of the part corrosion easily and having some setbacks, thereby cause shower door smooth and easyly not open or locking, can not reach desirable result of use.

Summary of the invention

The purpose of this utility model is to provide a kind of adaptation to be installed on the glass door sheet, can be in the structure improved bathroom door lock of operate as normal under the wet environment condition for a long time.

For reaching above-mentioned purpose, the utility model solves the technical scheme that its technical problem adopts: a kind of structure improved bathroom door lock, by shell, fixed head and one group of lock body intermediate plate parts are formed, wherein, one gland is corresponding with fixed head, and be connected and fixed with grub screw and tapered cup nut, the clamping glass door sheet is held successfully on the position in hole in advance to make a concerted effort, wherein, vertical core of planting on one fixed head, suit one sector gear on the axle core, with end that tight screw is fixed and with the tooth bar engagement, inlay in the specified channel that is fixed on a side in the lock tongue body, lock tongue body is sleeved in the shape chamber of shell, one spring base and spring assembly are in the outer hull shape chamber in lock tongue body left side, and lock tongue body is subjected to the spring compressing that the lock tongue body head is stretched out outside the housing; Shell and fixed head link into an integrated entity with hexagonal socket head cap screw; One handle respectively is equipped with in the end of extending the housing two ends at the axle core, and fixes with ending tight screw.

Form of the present utility model can be divided into the two kinds of forms in limit, the left and right sides by assembling; The section configuration of its shell can be made into square, semicircle, circular arc, polygon, petal.Attached rubber cushion of one gland and gum cover are corresponding with the fixed head another side, and are connected with shell with grub screw one end, and end is held successfully on the position in hole in advance with the clamping glass door sheet of making a concerted effort in addition, joins the taper gum cover with tapered cup nut and is connected and fixed.Vertically fix with ending tight screw by each suit one scarce round handle of axle core two ends of lock housing and gland.The bathroom door lock that is assembled into is the nature blocking, and (dead bolt stretches out shell) must rotate handle (this moment, sector gear drove tooth bar and lock tongue body indentation lock housing) by hand and lock tongue be contracted retreat to door opening state (not establishing tapered end and key) in the time of will opening as the need door.

The advantage of bathroom of the present utility model door lock is: rational in infrastructure, and good looking appearance, easy and simple to handle.Can be assembled into the two kinds of forms in limit, the left and right sides according to the installation position different needs.Its material is used plastic-steel, copper, plastic cement and stainless steel, uses under the wet environment condition for a long time, can not get rusty, but and long-term work.

The specific embodiment

Below in conjunction with accompanying drawing structure of the present utility model is further described, sees also shown in Fig. 1～6:

The structure improved bathroom of the utility model door lock, by handle 1, spacer sleeve 2, tapered cup nut 3, taper gum cover 4, gland 5, glue gasket 6, gum cover 7, axle core 8, grub screw 9, hexagonal socket head cap screw 10, fixed head 11, spring base 12, spring 13, sector gear 14, end tight screw 15,18, shell 16, plastic-steel cover 17, lock tongue body 19, tooth bar 20 and formed.

Wherein: fixed head 11 planes be provided with a plurality of can be by the circular cone through hole of screw and axle core, the core 8 of planting in intermediate cylindrical hole, plane is fixed at middle suit one sector gear 14 of axle core 8 and with ending tight screw 15; With sector gear 14 engagement be the plastic-steel tooth bar 20 that is embedded in lock tongue body 19 inner side slots, lock tongue body 19 is placed in the shape chamber of shell 16 together with plastic-steel tooth bar 20, there are a spring 13 and spring base 12 in left side, rear end at lock tongue body 19, and spring base 12 is to be sleeved on the inner chamber that is fixed on shell 16 on the grub screw 9; Hexagonal socket head cap screw 10 passes the screw that fixed head 11 screws in shell 16, and fixed head 11 and shell 16 are assembled into an integral body; At this moment, the plane is stretched out at axle core 8 two ends, and grub screw 9 stretches out the plane from fixed head 11, is used for holding successfully in advance on the clamping glass door with joint efforts the position in hole with fixed head 11 corresponding glands 5 and glue gasket 6, gum cover 7.Tapered cup nut 3 and taper gum cover 4 screw on the grub screw 9 that stretches out the plane, are used for fastening shower door and are locked in glass door sheet.Stretching out a handle 1 of axle core each suit of 8 two ends on plane, and fixing with ending tight screw 18.

The bathroom door lock that enforcement assembles is blocking because of lock tongue body is subjected to spring 13 compressings to stretch out shell 16, only with hand rotary handle 1 when operation is opened, sector gear 14 on the axle core 8 is made plastic-steel tooth bar 20 moving linearlies of circular motion and its engagement at this moment, thereby makes lock tongue body 19 indentation shells 16 and the unlatching of realization lock.
