Abstract

The utility model relates to an improved lock casing body structure of a disc brake lock. The utility model comprises a U-shaped seat and a sleeve barrel, wherein, the U-shaped seat is stamped by a metal plate sheet of a proper thickness; a sheathing groove which can be sheathed on a disc brake disk of a motorcycle is arranged in the U-shaped seat; both sides of the U-shaped seat are outward bent with reinforcing plates; one end of the U-shaped seat is provided with a convex circular sheathing and combined part, wherein, the center part of which is penetrated with a lock bolt through hole; the other end of the U-shaped seat is provided with a lock bolt inserting hole which is corresponding to the lock bolt through hole. Through the structures, the sleeve barrel is sheathed on the sheathing and combined part of the U-shaped seat to be punched and riveted to cause the sleeve barrel and the U-shaped seat to be firmly combined into a whole to form a high strength lock casing body of the disc brake lock after heat treatment.

Description

The lock housing body construction of improved disc brake lock

The relevant a kind of motor bike disc brake dish knot of locking that is used to be linked in of the utility model rotates with the restriction motorcycle front-wheel, and then reaches the lock housing body construction that the improved disc brake of anti-theft feature is locked.

The lock housing body of at present general disc brake lock, shown in the conventional stereo figure of Fig. 1, mostly be with the moulding of die casting mode, can be and be provided with one thereon for the open slot 1 that is placed on the motor bike disc brake dish, and within it portion be provided with one with open slot 1 core accommodation chamber 2 in vertical direction, for ccontaining core, and a lateral margin of this core accommodation chamber 2 is provided with one and wears hole 3, between core accommodation chamber 2 and open slot 1, be provided with a locking bolt through hole 4 in addition, locking bolt for core passes, open slot 1 inwall is provided with a locking bolt inserting hole 5 at locking bolt through hole 4 opposite positions, plants for the locking bolt of core.

Aforesaid conventional confguration has following defective: 1, it is with the moulding of die casting mode, do not have any reinforced structure and can't carry out intensive treatment, thereby intensity is relatively poor; 2, need behind its die cast to move through fraising and removal burr earlier,, thereby increase man-hour again through polishing and baking vanish action, manufacturing cost improves, 3, it is with the moulding of die casting mode, thereby needs certain thickness and cause weight to increase, and material cost and traffic cost improve relatively; 4, it is moulded fixing, can't be changed, and texture is relatively poor.

Main purpose of the present utility model provides a kind of lock housing body construction of improved disc brake lock, and its U type seat is provided with two stiffening plates, and U type seat can be through heat treatment reinforcement after making up with sleeve, thereby intensity is preferable.

Secondary objective of the present utility model provides a kind of lock housing body construction of improved disc brake lock, and its processing action is simple and easy rapidly, reaches and shortens man-hour, and manufacturing cost reduces.

Another purpose of the present utility model provides a kind of lock housing body construction of improved disc brake lock, its U type seat is that the metal sheet with suitable thickness is stamped to form, thereby overall weight is light, and material cost and traffic cost reduce, and lightly can simple and easyly carry, comfort feature improves.

A purpose more of the present utility model provides a kind of lock housing body construction of improved disc brake lock, and its appearance cladding has a plastic layer, and this plastic layer can be changed simply, reach integral body and be rich in variability, and texture is preferable.

The purpose of this utility model is achieved in that a kind of lock housing body construction of improved disc brake lock, it comprises: a U type seat and a sleeve, wherein U type seat inside is provided with a fit slot that can supply to be placed on the motor bike disc brake dish, and sleeve one lateral margin is provided with one and wears the hole; It is characterized in that: U type seat is that the metal sheet by a suitable thickness is stamped to form, each bends the stiffening plate of a proper width outward its both sides, one end is provided with the circular casing-joining part of a projection, this circle casing-joining part can supply sleeve to be nested with and carry out punching press riveting knot, the casing-joining part of sleeve and U type seat is firmly integrally combined, through heat treatment, promptly become a high-intensity disc brake lock case of lock body again.

It is as follows that following conjunction with figs. describes preferred embodiment of the present utility model in detail:

Fig. 1 is the block diagram of traditional product structure.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a three-dimensional combination figure of the present utility model.

Fig. 4 is an embodiment block diagram of the present utility model.

Be illustrated in figure 2 as three-dimensional exploded view of the present utility model, it comprises: a U type seat 10 and a sleeve 20, wherein U type seat 10 is that metal sheet by a suitable thickness is through punch forming, its inside is provided with one can be for the fit slot 11 that is placed on the motor bike disc brake dish, each bends the stiffening plate i2 of a proper width outward both sides, one end is provided with the circular casing-joining part 13 of a projection, circular casing-joining part 13 centres provide a locking bolt through hole 14, it is relative with this locking bolt through hole 14 that the other end is provided with locking bolt plant 15, and sleeve 20 1 lateral margins are provided with one and wear hole 21.

Be illustrated in figure 3 as three-dimensional combination figure of the present utility model, its when combination, sleeve 20 is placed on the casing-joining part 13 of U type seat 10 and carries out punching press riveting knot, the sleeve 20 and the casing-joining part 13 of U type seat 10 firmly are combined into one, promptly simple and easyly finish combination; And making up after heat treatment reinforcement promptly becomes high-intensity motor bike disc brake lock case of lock body.

Be illustrated in figure 4 as embodiment block diagram of the present utility model, when it desires to make the disc brake lock, core 30 is inserted in the sleeve 20 of above-mentioned lock housing body, and pass the wearing hole 21 of sleeve 20 and insert the pin hole internal fixation that core 30 lateral margins set in advance with a latch, clad a plastic layer 40 in lock housing body appearance again, promptly make disc brake lock; And can be in use, being sleeved on the motor bike disc brake dish with the fit slot 11 of this disc brake lock, the locking bolt that makes core 30 is passed by the locking bolt through hole 14 of U type seat 10, and passes the circular hole of disc brake dish, is inserted in the locking bolt inserting hole 15 of U type seat 10 again, finishes the action of locking.

By the structure of above-mentioned specific embodiment, can obtain following benefit: 1, its U type seat 10 is provided with two stiffening plates 12, and can gain in strength through heat treatment after U type seat 10 and sleeve 20 combinations, thereby integral intensity is preferable; 2, its processing action is simple and easy rapidly, thereby can shorten the cost-cutting in man-hour; 3, its U type seat 10 is to be stamped to form with metal sheet, thereby overall weight is light, and material cost and traffic cost reduce, and lightly can simple and easyly carry, comfort feature improves: 4, its appearance cladding has a plastic layer 40, and plastic layer 40 can simple and easyly change, thereby integral body is rich in variability, and texture is preferable.
