Description
(1) technical field
The utility model relates to a kind of lock(ing) bolt.
(2) prior art
Existing lock(ing) bolt comprises the bolt cap and is located at tightening latch under the bolt cap, is provided with play the role of fastening Thread Forming TF or thread in the bottom of tightening latch.During use, be easy to come off, can not well two objects be fixed.
(3) model utility technological scheme
When the purpose of this utility model provides a kind of use, be not easy to come off, can be well with two lock(ing) bolts that object is fixedly connected.
In order to achieve the above object, its technological scheme is, comprises the bolt cap and is located at tightening latch under the bolt cap, is provided with Thread Forming TF or the thread that plays the role of fastening in the bottom of tightening latch, is provided with the groove of being convenient to operate on the bolt cap; It is characterized in that be provided with the positioning block more than two on the top of tightening latch, the diameter of positioning block is greater than the diameter of its underpart Thread Forming TF or thread.
It further is improved to, and the axial distance L between the positioning block equates.Above-mentioned groove is straight groove or cross recess or cross popped rice groove.
The utility model advantage compared with prior art is, during use, is not easy to come off, can be well that two objects are fixedly connected; Production and processing easily, low price.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an another embodiment structural representation of the present utility model.
(5) embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, comprise bolt cap 2 and be located at tightening latch 3 under the bolt cap, be provided with Thread Forming TF or the thread 5 that plays the role of fastening in the bottom of tightening latch 3, be provided with the groove of being convenient to operate 1 on bolt cap 2, this groove 1 is straight groove or cross recess or cross popped rice groove; Be provided with four positioning blocks 4 on the top of tightening latch 3, also can establish the positioning block more than four, the axial distance L between the positioning block 4 equates that the diameter of positioning block 4 is greater than the diameter of its underpart Thread Forming TF or thread 5; Also available Thread Forming TF of the effect of this positioning block 4 or thread replace, and as shown in Figure 2, its diameter is greater than the diameter of its underpart Thread Forming TF or thread 5.During use, because the part of two sections different-diameters is arranged, when one section screw thread was inoperative, another section screw thread can effectively be fixed two articles also in action.
