Description

【考案の詳細な説明】（産業上の利用分野）本考案は、円筒状の錠本体が被着体に回転不能
に取付けられる錠前に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lock in which a cylindrical lock body is non-rotatably attached to an adherend.

（従来の技術）従来の錠前では、円筒状の錠本体の螺子部両側
面を平行に切除して平面部を設け、この錠本体の
断面と合致する小判形の取付孔を被着体に設け、
錠本体を該取付孔に嵌入れて錠本体の回転を阻止
し、錠本体前端の鍔部と背面から螺合した締付ナ
ツト間に被着体を挟込んで固着していた。(Prior art) In conventional locks, both sides of the screw part of the cylindrical lock body are cut out in parallel to provide a flat part, and an oval-shaped mounting hole that matches the cross section of the lock body is created in the adherend. ,
The lock body is fitted into the mounting hole to prevent rotation of the lock body, and the adherend is sandwiched between the flange at the front end of the lock body and a tightening nut screwed together from the back side to secure the lock body.

（考案が解決しようとする問題点）しかしながら、このような取付構造では、錠本
体側面の平面部分の肉厚が薄くなつて強度が低下
し易く、これを回避するには精度の高い加工を要
する。また、単なる円形孔と異なり、被着体に小
判形の取付孔を設けるのは容易でなく、手間とコ
ストがかかる。(Problem that the invention aims to solve) However, with this type of mounting structure, the wall thickness of the flat part on the side of the lock body becomes thinner and the strength tends to decrease, and to avoid this, highly accurate machining is required. . Further, unlike a simple circular hole, it is not easy to provide an oval-shaped attachment hole in an adherend, and it is time-consuming and costly.

従つて本考案の目的は、錠本体に対する精度の
高い切除加工を必要とせず、被着体に対する手間
のかかる孔明け加工も不要である錠前を提供する
ことである。 Therefore, an object of the present invention is to provide a lock that does not require highly accurate cutting of the lock body and does not require time-consuming drilling of the adherend.

The lock of the present invention includes a cylindrical lock body 1, a rotor 2 fitted in the lock body 1, It consists of a locking member 3 that locks the rotor 2 and the lock body 1, and a pin 4 inserted in the transverse direction of the lock body 1. One end of the pin 4 is engaged with the step groove 5 of the rotor 2, and the lock body 1 The other end of the pin 4 protruding from the side surface is engaged with a notch 9 connected to a mounting hole 8 of an adherend 7.

製作コストの節減も可能である。(Effect of the invention) As described above, in the lock of the invention, one end of the pin 4 inserted into the lock body 1 is engaged with the stepped groove 5 of the rotor 2, while the other end of the pin 4 is connected to the mounting hole 8. Since the notch 9 is engaged with the lock body 1, there is no need for a highly accurate cutting process to provide a flat surface on the side surface of the lock body, and there is no risk of reducing the structural strength of the lock body 1. Furthermore, the mounting hole 8 itself has a circular shape that is easy to process, and it is only necessary to provide a notch 9 at the edge of the hole, thereby eliminating the need for the conventional and time-consuming drilling process. Furthermore, since the pin 4 also serves as a member for preventing the rotor 2 from being pulled out, the number of components of the pin tumbler lock does not increase, and the manufacturing cost of the pin tumbler lock can be reduced.
