Abstract

The utility model relates to an integrally shaped lock base of a puzzle lock. At least one base plate and two lateral plates are integrally shaped in injection with plastic. Plastic elastic sheets of which the number is equal to the number of digit wheels are integrally shaped in injection on the base plate with plastic. The elastic sheets which are inclined upwards are bunted on the bottom surfaces of the digit wheels, so that the digits of the digit wheels are positioned easily after rotated. In addition, two end plates which are integrally shaped are arranged at both ends of the base plate. Circular holes for the penetration of both ends of shaft levers in the axial centers of the digit wheels for combination and orientation are arranged on the two end plates. Because the lock base is integrally shaped with plastic, the parts of the puzzle lock are reduced. The utility model has the advantages of simple manufacture, simple assembly, low cost, mass production, light weight, labor saving in transportation, less workload of punch presses and little environmental pollution which is resulted from plating.

Description

Integrally shaped base of puzzle lock

The utility model relates to the suitcase combination lock, is meant a kind of integrated combination lock lock especially.

By prior art as can be known, the suitcase combination lock all is to be provided with its many sets of numbers of upper sleeve through wheels of a long shaft rod on a lock, be generally three groups, and be subjected to those number wheels to control the locking screen that to do lifting, this type of combination lock structure can be with reference to No. 7024883 (the announcing No. 41751) of being applied for before the inventor and the lockset that appends two (announcing No. 092840), two cases for No. 7027299 structure, this type of combination lock also can find case before many relevant combination locks before the patent gazette by checking and approving in the case, its structure is very approximate haply, just all has following shortcoming usually:

1. the part of Gou Chenging is a lot of, and assembly is time-consuming, the manufacturing cost height.

2. most of part is the punch ram goods, must just can finish manufactured part through many roads manufacturing procedures, and for example iron plate is through punch forming, plating and then by manually being assembled, the trouble of not only getting the raw materials ready, and part is heavy, and effort is moved in carrying.

3. when each group number code wheel is rotated, its 0-9 numeral can be located exactly, usually must be provided with a sheet metal element in addition, form a plurality of shell fragments with the punch press punching out on it and make its location, even the sensation of lattice is arranged when also digit wheel rotates with the translot that blocks the digit wheel wheel face.

The purpose of this utility model is to overcome the above-mentioned defective of existing in prior technology and a kind of integrated combination lock lock is provided.The required Assembly part of this combination lock lock reduces, and makes conveniently, reduces institute and uses manually, the reduction manufacturing cost.And lock weight saving, carry more convenient and laborsaving.In addition, multinomial element and lock is one-body molded, reduce the element that punch press is made, so reduced plating work, reduced environment pollution.

For achieving the above object, the integrated combination lock lock of the utility model is that plastic cement one injection molding has a base plate and biside plate at least, be primarily characterized in that, combination lock lock base plate penetrates the one-body molded plastic cement shell fragment that equates with the digit wheel number with plastic cement, those shell fragments are past interior upwards inclined from lock one side, just be positioned at the digit wheel below and have suitable elasticity,, each numeral can accurately be located in order to hold digit wheel surface translot.

The integrated combination lock lock of the utility model inferior one is characterised in that this all one-body molded two end plates that are provided with in combination lock lock base plate two ends, has two circular holes on this two end plate for the inlay card location, axostylus axostyle two ends of passing digit wheel central authorities.

About detailed construction of the present utility model, function and characteristics, can fully be understood by the detailed description of following examples conjunction with figs..

Fig. 1 is the stereogram of the integrated combination lock lock of the utility model one embodiment;

Fig. 2 is the stereogram behind the lock assembling digit wheel shown in Figure 1;

Fig. 3 is the sectional view along 3-3 cross section intercepting among Fig. 2;

Fig. 4 is the stereogram of the integrated combination lock lock of another embodiment of the utility model;

At first see also shown in Figure 1, this lock (10) is a plastic cement one ejection formation, it comprises a base plate (11), be substantially a flat board, it longitudinally is provided with two side plates (12) (13) in both sides, its base plate (11) is gone up the one-body molded three inclination shell fragments (14) (15) (16) that are provided with in appropriate location, the proper intersection of one end of those shell fragments (14) (15) (16) is in the root edge place of side plate (12), and the other end is inclined upwardly toward in and make and have suitable elasticity when pressing down, in order to make these three shell fragments (14) (15) (16) can plastic cement one ejection formation, this base plate (11) be gone up relative position and is had three open-works (17) (18) (19).In addition, another body formed two end plates (21) (22) that are provided with of this lock (10) appropriate location, two ends, these two end plate (21) (22) both sides also combine with two side plates (12) (13), have two circular holes (23) (24) and two lateral opening (25) (26) on it.

Shown in Fig. 2 and 3, when above-mentioned this lock (10) uses for the combinations of numbers lock, system penetrates the protuberance at lockmaking screen (31) two ends in two lateral opening (25) (26) on this two end plate (21) (22) and locatees, again three sets of numbers wheels (32) (33) (34) are worn together with axostylus axostyle (35), this axostylus axostyle (35) two ends penetrate respectively in two circular holes (23) (24) on this two end plate (21) (22) and finish combination, very easy, and three shell fragments (14) (15) (16) that are used on this base plate (11) are distinguished roof pressure in the bottom surface of digit wheel, the sensation that lattice is arranged when digit wheel is rotated, its 0-9 number can accurately be located, numeral is arranged easily check the number.

If the foregoing description is compared with habitual similar combination lock, its action and use principle and habitual lock are identical, be that lock of the present utility model (10) is with plastic cement one ejection formation, at least four parts that replaced habitual combination lock, the part of combination lock is significantly reduced, reduce and make and assembly cost, and habitual lock is light with metal punch forming element weight, carry laborsaving, reducing the punch press workload and reduce environment pollution that electroplating processes causes and cost, therefore is the combination lock of a suitable mass-produced improvement design.

As shown in Figure 4, this lock (40) structure is identical with previous embodiment substantially, institute's difference is that its side plate (41) locates to be provided with two through holes (42) (43), and base plate (44) is provided with a prominent point (45) and uses to be applicable to another kind of type combination lock.
