The utility model relates to a pulling buckle of a basket child safety seat. The pulling buckle of the basket child safety seat comprises a shell and an insertion sheet, wherein the insertion sheet can be inserted into an inner cavity of the shell to be locked, an insertion opening is formed in the front end of the inner cavity of the shell, the insertion sheet can be inserted into the insertion opening, an ejection spring is arranged at the rear end of the inner cavity of the shell and can abut against the insertion sheet in an elastic mode, a button is arranged on the end face, without the insertion opening, of the shell or the side face, without the insertion opening, of the shell, an insertion hook is arranged at the insertion end of the insertion sheet and faces the end face opposite to the end face with the button, or the side face opposite to the side face with the button, a clamping hook is arranged in the inner cavity of the shell, the insertion hook faces the portion with the clamping hook, the clamping hook and the button are integrated, the insertion hook and the clamping hook are connected in a corresponding clamping mode or are in the separation state, the clamping hook or the button is movably arranged in the inner cavity of the shell in a rotatable connection mode through a fixed shaft which is parallel to the end face of the button and perpendicular to the insertion direction of the insertion sheet, and the clamping hook and the inner cavity of the shell are connected through a clamping connection spring. Due to the fact that the clamping hook which is driven by the button to rotate in an integrated mode is correspondingly combined with the insertion sheet and the insertion hook in an insertion mode and is separated from the insertion sheet and the insertion hook, the pulling buckle is inserted or pulled out, and the pulling buckle is simple and compact in structure, convenient to install and use and flexible in insertion operation and buckle pulling operation.

Description

A kind of hand basket child safety seat pulls out to be buckled

Technical field

The utility model relates to a kind of safety belt with pulling out button, is that a kind of hand basket child safety seat band is buckled with pulling out specifically.

Background technology

In American-European countries, neonate is owing to being in the primary stage of body development, and health is less, is easy to come to harm, and necessarily requires to use child safety seat while leaving hospital, and is fastened one's safety belt to baby by nurse, guarantee safe and punctual rear just permit leave.Hand basket child safety seat can meet baby's instructions for use preferably, and seat is mainly installed on automobile by safety belt, and therefore the locking of the fastening of safety belt is extremely important.The existing patent No. is 200320110901.3 disclosed safety buckles, adopt hook to coordinate rotor plate step locking inserted sheet in housing, and the guiding surface on it promotes rotor plate and overcomes lower stage clip active force and unclamp the locking of step to insertion tab hook by button, realize respectively thus safety buckle plug together locking and button trip, but press the active force of button in the time that guiding surface acts on rotor plate, active force disperses, and presses required dynamics larger, the effort, stiff of triping; Before establishing in housing, under, three stage clips of side realize respectively inserted sheet eject, rotor plate reset and push-button reset, three stage clips are respectively towards three directions in space, in limited housing inner chamber, difficulty is installed, and the functional part of corresponding each stage clip is many, structure is loaded down with trivial details, fragile, affects safety buckle serviceability.

Summary of the invention

For child safety seat buckle complex structure in prior art, difficulty is installed, fragile, the deficiency of the poor performance of triping, it is a kind of simple in structure, compact that the utility model provides, installation, easy to use, and the hand basket child safety seat that plugs together and pull out button flexible operation pulls out to be buckled.

The technical solution adopted in the utility model is: a kind of hand basket child safety seat pulls out to be buckled, comprise shell and can insert the inserted sheet of shell inner cavity locking, the front end of shell inner cavity is provided with the socket that can plug together inserted sheet, the rear end of shell inner cavity is provided with the spring that ejects that can elasticity pushes against inserted sheet, its technical characterstic is, on the non-socket end face of described shell or side, button is set, the insertion end of inserted sheet is provided with towards with button, the relative end face of end face or side or the inserting hook of side being set, inserting hook towards shell inner cavity in be provided with and the grab of button disjunctor, inserting hook is corresponding clamping or disengaged condition with grab, grab or button are through being parallel to button end face and being rotatably connected in shell inner cavity perpendicular to the fixed axis activity that inserted sheet plugs together direction, between grab and shell inner cavity, be connected through clamping spring.

Further, the mouth of hook of described inserting hook is corresponding clamping or disengaged condition with the mouth of hook of grab, and the mouth of hook back of inserting hook and the mouth of hook back of grab are guiding surface or smooth curved surface.

Further, described inserted sheet is one chip or double-disk, and inserting hook is arranged in biplate on any one or two.

Again further, described clamping spring is volute spring, volute spring be arranged at grab and inserting hook towards shell inner cavity chamber wall between.

Compared with prior art, the utility model has the advantages that:

1, pull out and detain while plugging together, inserted sheet inserts shell inner cavity, the mouth of hook back of inserting hook promotes the mouth of hook back of grab, grab overcomes volute spring active force and rotates towards volute spring around fixed axis, grab plugs together and in direction, dodges grab at inserted sheet, inserted sheet continues to stretch into shell inner cavity and makes the mouth of hook of inserting hook and the corresponding clasp joint of the mouth of hook of grab of inserted sheet, now the inserting end of inserted sheet pushes against and ejects spring, eject spring reaction force acts in the clasp joint of inserting hook and grab, effectively guarantee that inserted sheet plugs together locking, improve and plug together stable and firm performance;

2, pull out and detain while pulling up, press the button, button drives grab to rotate towards volute spring around fixed axis, grab plugs together and in direction, dodges grab at inserted sheet, the inserting end of inserted sheet is ejected spring reaction force and is ejected to shell inner cavity front end outside, makes the stagger mouth of hook of grab of the mouth of hook of the inserting hook of inserted sheet throw off locking and realize and pull out button; In the time that the mouth of hook of the inserting hook of inserted sheet staggers the mouth of hook of grab, eject spring and continue outwards to eject inserted sheet, and grab resets under the reaction force of volute spring after Panasonic's button, outside impetus is played to the mouth of hook back of inserting hook in the mouth of hook back of grab, further improves and pulls out button efficiency and flexibility ratio.

The utility model adopts to be plugged together and got loose by the corresponding inserted sheet inserting hook of grab of button one driven rotary realizes the plug of pulling out button, and it is simple in structure, compact, and installation, easy to use, plugs together and pull out button flexible operation.
