Abstract
The invention discloses a tapping-free screw hole locking structure, which comprises a screw and a fixed plate, wherein a die punching fixed with the screw in a matching mode is arranged in the fixed plate. The inner wall of the die punching is punched into spiral matched with the external thread of the screw. With the adoption of the tapping-free screw hole locking structure, the die punching in the fixed plate is convenient to process, no internal thread is trapped in the die punching as required, and only the inner wall of the die punching is punched into spiral matched with the external thread of the screw, therefore, the fixed plate and the screw can be locked. The locking structure of the screw hole is simple in structure, convenient to process, and is shaped at one time. Without affecting the screw and the fixed plate to be matched in a suppression mode, the production capacity of the products is improved, and the production cost of the products is reduced.
Description
Technical field
The present invention relates to the screw hole lock and pay structure, relate in particular to a kind of screw hole lock of exempting from tapping and pay structure.
Background technique
In the existing display product, use screw that sheet material and metal iron pan are locked pair.Attack the internal thread operation with screw lock pays that the tapped hole that cooperates all need carry out manual work or machinery on the metal iron pan, thereby the internal thread of the tapped hole on the outside thread that makes screw and the metal iron pan cooperates, reach the purpose of locking pair.
Internal thread in the tapped hole need carry out manual work or machinery and carry out processing and fabricating separately, needs to drop into lot of manpower and material resources, processes each tapped hole simultaneously and can produce certain expense.Use the metal iron pan to be example with TV; Each metal iron pan uses about about 13 of screw hole, in process of producing product, need carry out man-to-man internal thread machining to 13 screw holes; So not only influence the production capacity of product, and increased the whole cost of product.
Summary of the invention
The purpose of this invention is to provide a kind of easy to process and screw hole lock that cost is low exempts from tapping and pay a structure.
For realizing above-mentioned purpose; A kind of screw hole lock of exempting from tapping of the present invention is paid structure; It comprises screw and fixed plate, is provided with the die punching with the screw matching and fixing in the said fixed plate, and the impact briquetting of said die punching inwall has the spirality that is complementary with the screw outside thread.
Said die punching one side is provided with the fluting breach.
Said fixed plate is a metalwork.
The thickness of said fixed plate is below 1.5mm.
The screw hole lock of exempting from tapping among the present invention is paid a structure, not only can be used for display product, and can also be used for other has and relate to screw and pay a product of fixing with the fixed plate lock.
The screw hole lock that adopts the present invention to exempt from tapping is paid a structure, and the die punching on the fixed plate is easy to process, need not to attack internal thread in the die punching, only needs the spirality that is complementary at impact briquetting of die punching inwall and screw outside thread, can lock pair a fixed plate and a screw.The lock of this screw hole is paid simple in structure, and is easy to process, once promptly plastic, under the situation that does not influence screw and fixed plate confinement coupling, improved the production production capacity of product, reduces the production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:
Fig. 1 pays the structural representation of structure for the screw hole lock that the present invention exempts from tapping;
Fig. 2 is the side view of fixed plate of the present invention and screw lock pair structure;
Fig. 3 is the structural representation of fixed plate of the present invention.
Embodiment
Shown in one of Fig. 1-3; A kind of screw hole lock of exempting from tapping of the present invention is paid structure; It comprises screw 1 and fixed plate 2, is provided with the die punching 3 with screw 1 matching and fixing in the said fixed plate 2, and said die punching 3 inwall impact briquettings have the spirality 31 that is complementary with screw 1 outside thread.
Adopt above structure, the hole that cooperates with screw 1 on the fixed plate 2 adopts mould to carry out punching, simultaneously in stamping process; The spirality 31 that die punching 3 inwall impact briquetting one-tenth and screw 1 outside thread are complementary; Thereby die punching 3 inwalls need not to attack internal thread, and a punching press is promptly plastic, easy to process; The spirality 31 of die punching 3 inwalls can be paid with the outside thread lock of screw 1, reaches screw 1 is fixed in the purpose in the die punching 3.
Said die punching 3 one sides are provided with fluting breach 4.Die punching 3 inwalls are provided with spirality 31; In punch process, the die punching 3 terminal flangings 32 that form are not so the clearing end of spirality 31 and fixed plate 2 be or not same plane; So in die punching 3 one sides fluting breach 4 is set, avoids interfering screw 1 underspin; Simultaneously, be provided with fluting breach 4 after, can also make the spirality 31 of die punching inwall and the outside thread resilient engagement of screw 1, so not only make fixed plate 2 and screw 1 fixation, and the spirality 31 of die punching inwall is not fragile.
Said fixed plate 2 is a metalwork.
The thickness of said fixed plate 2 is below 1.5mm.
Claims (4)
1. a screw hole lock of exempting from tapping is paid a structure, and it comprises screw and fixed plate, it is characterized in that: be provided with the die punching with the screw matching and fixing in the said fixed plate, the impact briquetting of said die punching inwall has the spirality that is complementary with the screw outside thread.
