Abstract

The utility model is a compression spring concealed thumb-latch, which is assembled by a baseplate 1, a latch head 2, a slider 3, a limited support 4, an arresting pin 5, a guide pillar 7, a spring 8, a boost slice 9, a deflector rod 10 and a pin roll 11. Whether the structure of the utility model thumb-latch is locked or unlocked, the deflector rod 10 is concealed in the concealing hole 12. The deflector rod 10 surface is flush with the baseplate 1 surface. The deflector rod 10 can agilely rotate in 180 degrees stirred by a finger. Consequently, the spring 8 and the boost slice 9 functions together to push the slider 3 to move. As a result, the latch head 2 can hold out and withdraw. The utility model is provided with concealing function; and is greatly difficult for people outside the door to stir and unbolt latch; the security is high, and the structure is ingenious and reasonable, and appearance is artistic, and with a good decoration effect arranged in the door and the window.

Description

Length of spring compressed built-in door angle catch

One, technical field

The utility model belongs to the housing window accessory, particularly a kind of thumb-latch.

Two, background technology

Existing housing window latch is generally two kinds of fitted outside or built-in types, and what they all adopted is straight selection structure.The thumb-latch of this straight selection structure is installed on door (window) fan or door (window) frame, is easy to after closing the doors and windows be pushed aside by the stranger robber, and its safety guarantee is relatively poor; In addition, their contour structures lacks aesthetic feeling, influences the whole decorative effect of housing window.

Three, summary of the invention

The purpose of this utility model is exactly the defective at the thumb-latch existence of existing straight selection structure, design a kind of length of spring compressed built-in door angle catch that structurally is different from existing product fully, make it to be assemblied on the door and window, elegant in appearance, good decorating effect, flexible and convenient operation during use is guaranteed safe and reliable.

The purpose of this utility model is achieved through the following technical solutions.

A kind of length of spring compressed built-in door angle catch includes base plate and fork, it is characterized in that:

1) it also has slide, limiting bracket, spacer pin, guide pillar, spring, boosting sheet, driving lever and bearing pin;

2) offer hiding hole at the middle part of base plate, hiding hole two middle side parts are provided with a pair of journal stirrup and base plate is connected as a single entity, limiting bracket is fixedly connected on the base plate of hiding the two ends, hole, and spacer pin is worn and is connected in the limiting bracket termination, offers the finger groove at the backplate surface that is close to limiting bracket;

3) slide places in the limiting bracket under the spacer pin, and an end is barb type and fork screwed connection, is the concave groove structure between two pairs of limiting brackets, and the concave groove top is offered porose;

4) lower end of guide pillar and boosting sheet are whole links to each other, and is provided with a pair of journal stirrup with the boosting sheet is connected as a single entity, and the guide column sleeve upper spring penetrates in the hole at concave groove top, and driving lever passes hides hole usefulness bearing pin and two pairs of journal stirrups flexible connections.

The length of spring compressed built-in door angle catch of the utility model structure adopts embedded mounting method to be assemblied on door (window) fan, gets final product offering a hole that is complementary with corresponding (window) frame of fork position.No matter door and window is at latch locking state or released state, be used to stir the fork mobile driving lever of stretching, contract, all be hidden in and hide in the hole, and with the flush of base plate; Finger stretches into and refers to touch the driving lever termination in the groove, can stir driving lever flexibly and do 180 degree rotations, thereby utilize the effect promotion slide of spring and boosting sheet to realize that the overhanging of fork or retraction move.The thumb-latch of the utility model structure has built-in function, and the stranger wants to separate very difficulty of pin, security reliability height from stealing outdoors to dial; And operation is very flexible; Its structure is ingenious rationally, and good looking appearance is generous, is assemblied in the good decorating effect on the door and window.

Five, the specific embodiment

Further specify the concrete structure of the utility model length of spring compressed built-in door angle catch and its operating principle below in conjunction with accompanying drawing.

A kind of length of spring compressed built-in door angle catch includes base plate 1 and fork 2, it is characterized in that:

1) it also has slide 3, limiting bracket 4, spacer pin 5, guide pillar 7, spring 8, boosting sheet 9, driving lever 10 and bearing pin 11;

2) offer hiding hole 12 at the middle part of base plate 1, the 12 liang of middle side parts in hiding hole are provided with a pair of journal stirrup 13 and are connected as a single entity with base plate 1, limiting bracket 4 is fixedly connected on the base plate 1 of hiding 12 two ends, hole, spacer pin 5 is worn and is connected in limiting bracket 4 terminations, offers on base plate 1 surface of next-door neighbour's limiting bracket 4 to refer to groove 14;

3) slide 3 places in the limiting bracket 4 under the spacer pin 5, and an end is barb type and fork screwed connection, is concave groove 6 structures between two pairs of limiting brackets 4, and concave groove 6 tops are offered porose;

4) 9 whole linking to each other of the lower end of guide pillar 7 and boosting sheet, and be provided with a pair of journal stirrup 13 and be connected as a single entity with boosting sheet 9, guide pillar 7 cover upper springs 8 penetrate in the hole at concave groove 6 tops, and driving lever 10 passes hides hole 12 usefulness bearing pins 11 and two pairs of journal stirrups 13 flexible connections.

Its operating principle is: the length of spring compressed built-in door angle catch of the utility model structure, no matter door and window is at latch locking state or released state, be used to stir the fork 2 mobile driving lever 10 of stretching, contract, all be hidden in and hide in the hole 12, and with the flush of base plate 1; Finger stretches into and refers to touch driving lever 10 terminations in the groove 14, can stir driving lever 10 flexibly and do 180 ° of rotations, thereby utilize the effect of spring 8 and boosting sheet 9 to promote the overhanging of slide 3 realization forks 2 or bounce back to move.
