Technical field

The utility model is related to a kind of button field, more particularly to a kind of piston type four-part button.

Background technology

Four-part button is one kind of button, widely used, and all kinds of clothes can be used, and has fixed and decoration function.Existing Have the four-part button in technology be usually be used cooperatively with female thread and pin thread, usual four-part button be divided into from top to bottom buckle side, catapult slot, Pearl and button four components of foot are detained, wherein buckle side and the combination of catapult slot forms female thread component, and catching groove is equipped among the catapult slot of female thread, Catching groove side is equipped with two parallel S type springs；It detains pearl and button foot combination forms pin thread component, a button is protruded among pin thread Foot, the button foot are pressed into the catching groove of female thread by S type spring clamps, i.e., by the button pearl that is set on pin thread with being set on female thread S types spring formed interference fit.Although such interference fit type can guarantee is fitted close between female thread and pin thread, but people In the dropout period of the day from 11 p.m. to 1 a.m, often require to use larger power i.e. both hands pull respectively female thread and the cloth of pin thread both sides can just make pin thread with Female thread separates, however the fixed form of existing four-part button and cloth is to be socketed and buckle pearl by buckle side and catapult slot and buckle foot Socket and clamping cloth are realized, so not only easily separated cloth with pin thread or female thread when firmly threading off, but also it is multiple Threading off also, easily for damage cloth so that cloth deforms, especially superior in quality cloth then seriously affects the entirety of clothes after deforming Aesthetic feeling.Therefore, how to ensure that people can conveniently, effortlessly complete dropout process when using four-part button and ensure pin thread And female thread and cloth be stably connected on the premise of it is not damaged to cloth when ensureing to thread off simultaneously be that people need the problem solved.

Utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple in structure, installation easily, Ensure the indeformable piston type four-part button of cloth during easy to use laborsaving and dropout.

To achieve the above object, the utility model provides a kind of piston type four-part button, and the four-part button includes female thread and public affairs Button, the female thread include buckle side and catapult slot, and the buckle side includes panel and fixed and hollow connection leg vertical with panel, institute Stating pin thread includes button pearl and button foot, is provided with piston type button in the middle part of the female thread, is provided in the middle part of the outer end face of panel The cylindrical type groove connected with connection leg, the internal diameter of cylindrical type groove are more than the internal diameter of connection leg；The piston type button is set There is button cap, button nail and resetting spring, the button cap to be provided with cap face and the cap column vertical with cap face, button nail be provided with nail face and with The vertical post in nail face, the cap column wall are provided with internal thread, and post outer wall is provided with corresponding with the internal thread of cap column External screw thread；The resetting spring is socketed in cap column and the post between cap face and nail face, and the diameter of button cap is recessed less than cylindrical type The diameter of slot, the diameter for following closely face are more than the diameter of connection leg.

The diameter or the internal diameter less than cylindrical type groove that the internal diameter of the resetting spring is less than nail face.

Cross mouth is provided on the nail face of the button nail.

The utility model advantageous effect is：The piston type four-part button of the utility model is simple in structure, and installation is easy；During dropout Piston cap only need to be pressed with finger the button foot of pin thread can be separated out of two on the catching groove side of female thread parallel S type springs It opens, not only operator is convenient and strength-saving, but also effectively eliminates because two hands firmly pull open pin thread and the cloth of female thread both sides respectively Cause the deformation and damage to four-part button periphery cloth, also avoid drawing the mode of pin thread and female thread both sides dress material because being employed many times The phenomenon that threading off and four-part button can be easily separated with cloth.

The piston type four-part button of the utility model is described further below in conjunction with the accompanying drawings.

Specific embodiment

As shown in Figure 1, the piston type four-part button of the present embodiment includes female thread and pin thread, female thread includes buckle side 1 and catapult slot 2, buckle side 1 includes panel 3 and fixed and hollow connection leg 4 vertical with panel 3, and pin thread includes button pearl 5 and button foot 6.As Fig. 2, Piston type button 7 is provided with shown in Fig. 3 and Fig. 4, in the middle part of female thread, is provided in the middle part of the outer end face of panel 3 and connects with connection leg 4 Logical cylindrical type groove 8, the internal diameter of cylindrical type groove 8 are more than the internal diameter of connection leg 4.Piston type button 8 is provided with button cap 9, button Nail 10 and resetting spring 11, button cap 9 are provided with cap face 12 and the cap column 13 vertical with cap face 12, button nail 10 be provided with nail face 14 and The post 15 vertical with nail face 14,13 inner wall of cap column are provided with internal thread 16, cross mouth 18 are provided on the nail face 14 of button nail 10, 15 outer wall of post is provided with and 16 corresponding external screw thread 17 of the internal thread of cap column 13；Resetting spring 11 is socketed on cap face 12 and nail On cap column 13 and post 15 between face 14, the diameter of button cap 9 is less than the diameter of cylindrical type groove 8, and the diameter in nail face 14 is more than The diameter of connection leg 4.The diameter or the internal diameter less than cylindrical type groove 8 that the internal diameter of resetting spring 11 is less than nail face 14, if multiple Position spring 11 internal diameter be less than nail face 14 diameter then resetting spring 11 is integrally located in connection leg 4, if resetting spring 11 is interior Footpath be less than cylindrical type groove 8 internal diameter then resetting spring 11 is integrally located in cylindrical type groove 8.

Female thread is fixed and can resetting spring 11 first be sleeved on button in the position that clothes and bag etc. need to install four-part button After on the cap column 13 of cap 9, then the resetting spring 11 on cap column 9 extend into along cylindrical type groove 8 in connection leg 4, Ran Houyong Button nail 10 from 2 end of catapult slot is entered and passes through the cap column 13 on button cap 9 with the button cap 9 on buckle side 1 by the screwdriver of cross mouth Internal thread 16 and the external screw thread 17 of the post 15 on button nail 10 are tightened.Because button cap 9 passes through the internal thread 16 of cap column 13 and post 15 External screw thread 17 tighten and with button nail 10 tighten it is integral, therefore need thread off when press...with one's finger lower piston formula button 7 button cap 9 then 14 end of nail face of button nail 10 can be caused to exit the foot 6 of buckleing of pin thread out of female thread catapult slot 2, so as to fulfill the effect easily threaded off Fruit, the problem of efficiently avoiding firmly threading off and cloth is caused to deform and damage.
