Abstract

The utility model relates to a soft key structure. A containing chamber of a key body is used for containing one end of a shell rod. The containing chamber is provided with a pair of wall tracks to be used for a pair of guiding blocks of the shell rod to move along the wall tracks. The shell rod is provided with a through pipe hole to be used for the penetration of one end of a rod body. One end of the rod body is fixed on a body. The other end of the rod body uses a pivoting element to pivot with a plurality of chain sections and each chain section is pivoted by the pivoting element. The surfaces of the chain sections and the rod body are provided with arc concave holes and a section on the terminal is provided with an inclined wall. The key can bear large torsion force and can be used for a long time with small length to be convenient for being carried.

Description

Soft key structure

The utility model relates to key, refers in particular to a kind of soft key structure, and it has less length, can be conveniently by portable.

In the prior art, the Taiwan patent gazette is announced No. 162749, " the lockset group with core of dioptric type keyhole ", as Fig. 7-shown in Figure 9, its key groove hole 92 with core 91 is designed to meander-like, and the key 93 of its cooperation also can bend, as shown in Figure 8; Its key 93 is by establishing most the small-sized guide blocks of arranging 932 on the bent shell fragment 931 of tool elasticity, and offers the tooth of knock-out pin pearl at a side of this shell fragment 931, as shown in Figure 9; Arc recess 933 is established on big surface at small-

sized guide block

932, and 932 of this small-sized guide blocks are flexible according to duricrust pipe 94 and flexible package 95, make small-sized guide block 932 can deeply form the key groove hole 92 of the core 91 of meander-like.Its major defect is:

Above-mentioned key can only be established the tooth of joining the hole with the pin pearl on a side direction limit of shell fragment 931, or establishes arc recess 933 on small-sized guide block 932 1 big surfaces.Generally speaking, the key that this kind is commonly used forms bigger thickness, and owing to possess duricrust pipe 94 and flexible package 95, therefore, whole key 93 also has bigger length, is inconvenient to carry.And this key 93 can't be offered arc recess simultaneously at two big faces of small-sized guide block 932, and therefore, the use of this key is also inconvenient, and promptly the direction of insertion of key is restricted, and has directionality.And this is configured in when receiving minimum length, still has shell fragment 931 and small-sized guide block 932 partly to expose outside flexible package 95, so causes easily and colludes the situation of drawing clothing and damaging clothing.

The purpose of this utility model provides a kind of soft key structure, overcomes the drawback of prior art, reaches and can bear the bigger strength of reversing, can use by anti-longer-term, and the portable again purpose of smaller length.

The purpose of this utility model is achieved in that a kind of soft key structure, by key body establish room for shell bar one end hold into, this room is established a pair of wall rail and is moved according to this wall rail for a pair of guide block of shell bar, this shell bar has the pore of perforation to pass for the body of rod one end, the body of rod one end is fixed on body, and body of rod end in addition articulates most chain links with pivot connecting element, and the chain internode also articulates with pivot connecting element, the body of rod and link surface are established arc recess, and terminal chain link is established skew wall.

Insert between this shell rod end surface and body and have elastic component, the shell masthead is pushed away protruding from body; This body of rod is provided with arc recess, and the lower pin pearl of the core pin pearl group that this arc recess is engaged coincide; Upper and lower two sides of this body of rod are provided with teeth groove, and the lower pin pearl of the core pin pearl group that this teeth groove is engaged coincide.

Major advantage of the present utility model is to bear the bigger strength of reversing, can be anti-longer-term use, and smaller length arranged and be easy to carry.

Describe in detail below in conjunction with preferred embodiment and accompanying drawing.

Consult shown in Fig. 1,2, the utility model includes members such as key body 1, shell bar 2, the body of rod 3.

The head that is held of body 1 is provided with a room 11 and inserts for an end of the shell bar 2 and the body of rod 3, and room 11 has a pair of wall rail 13, and wall rail 13 relies on for the guide block 31 of shell bar 2, moves in order to guiding shell bar 2, and the cylinder 12 of body 1 is fixed an end of the body of rod 3.

This housing 2 is metal, hard plastic cement or plastic-steel structure, this shell bar 2 can be placed into the room 11 at body 1, and rely on the wall rail 13 of body 1 by the guide block 21 of a pair of protrusion, in order to moving of guiding and restriction housing 2, for making housing 2 can make things convenient for telescopic moving, a flexible member 22 has been inserted on the wall rail 13 end limits of housing 2 end faces and body 1, and the other end of shell bar 2 can be protruded in body 1 outside by pushing tow, the perforation pore 23 that the own tool of housing 2 one is hollow, pore 23 moves within it for the bodies of rod 3.

The body of rod 3 is a metal construction, by housing 2 and body 1, and is fixed on body 1 by locating hole 31 by cylinder 12 by an end, and the body of rod 3 end in addition articulates most chain links 33 with pivot connecting elements such as pin 32, and 33 of each chain links are done to articulate mutually with pivot connecting element 32; Respectively be provided with arc recess 34 on the body of rod 3 and the chain link 33, and this arc recess 34 can be formed on two of the body of rod 3 maximum surfaces, consult shown in Figure 4; And become to be symmetrical arranged according to this body of rod 3 central axiss, arc recess 34 can the knock-out pin pearl, upper and lower pin pearl 43,44 defibers of pin pearl group can be alignd, as shown in Figure 6 with core 41 with lock body 42 defibers; Hold most the chain link 33 on limit to establish skew wall 35, rise in order to guiding knock-out pin pearl, in case of necessity, the upper and lower dual side-edge of this body of rod 3 can be established teeth groove 36, and therefore, the lockset group 4 that is used with this body of rod 3 promptly can form the pin pearl group of tool multiple row, reaches higher-security.

Consult shown in Fig. 2-4, after the utility model combination, this housing 2 is subjected to flexible member 22 pushing tows, forms and stretches out outside body 1, forms the maximum length of whole key this moment.

Consult shown in Fig. 5,6, when doing to open use with this key, 2 pairs on shell bar is positioned at the core 41 set key groove holes of core group 4, and body 1 is imposed the strength of insertion, 2 retractions of shell bar are in the room 11 of body 1, and the body of rod 3 and chain link 33 can enter at core 41 set key groove holes, therefore, teeth groove 36, arc recess 34 by the body of rod 3 and chain link 33 are coincide by lower pin pearl 44, upper and lower pin pearl 43,44 defibers of pin pearl can be alignd with lock body 42 defibers with core 41, form core 41 and can be driven rotation by the body of rod 3.

Structure of the present utility model; the body of rod on the key can be inserted in core; therefore; from the strength of reversing that drives the core rotation; be to bear by the body of rod, can directly be added in the pivot connecting element that articulates chain link, so; the access times of key can increase; can prolong the application life of key, and this shell bar can also be as the usefulness of guiding chain link, when key does not use; this chain link can retraction in the shell bar; so, this key can form smaller length, can be convenient for carrying; and chain link is not fragile by shell bar protection, and chain link can not colluded draw and damage clothing.
