Detailed Description

The construction and use of the utility model will now be further described with reference to the accompanying drawings. As shown in figures 1-7, one end of a handle 1 of the pulling aid is bent downwards and fixed in an inner groove 801 in a base 8 through a second pin 3, a second pin of the handle is provided with a self-locking section 101 bent upwards and arched upwards, a first pin 2 penetrates through the base and is inserted into the self-locking section of the handle in the base and a sliding hole 402 at one end of a clamping plate 4, the clamping plate is arranged in a plate groove 102 at one end of the self-locking section of the handle, the other end of the clamping plate is provided with an open locking notch 401, a convex clamping head 404 is arranged at the lower edge of the locking notch of the clamping plate, the clamping head is outwards enlarged and is convex, the lower opening of the locking notch is higher than the upper opening, the clamping plate at the end is fixed in the inner groove of the base through a third pin 5 at the locking notch, a torsion spring 9 is arranged at the third pin, two ends of the torsion spring are respectively fixed at the edge groove at one side of the locking notch of the clamping plate and the edge at the other side of the clamping plate, a positioning piece 7 is arranged in the base below of the end, the positioning piece is fixed in the base through a fourth pin 6, a notch is formed in one side of the front end of the positioning piece, and the notch of the positioning piece is positioned below the locking notch of the clamping plate; when the handle drives the cardboard linkage, the cardboard drives the setting element and swings in the base inside groove, drives the fore shaft of cardboard and exposes the base when the handle is pulled upwards, and the first pin of handle slides in the slide opening of cardboard. The concrete structure is as follows: the positioning piece is V-shaped, the V-shaped groove of the positioning piece is fixed in the inner groove of the base through a fourth pin to swing, and a groove 405 is formed in the edge below one side of the positioning piece at the fixing position of the torsion spring below the locking opening of the clamping plate; a limiting hole 701 is formed at the convex point end of the positioning piece, and a convex edge protruding downwards is arranged on one side of the locking notch at the groove of the clamping plate; the spacing hole of setting element corresponds recess one side border below of cardboard and is equipped with bellied pothook 403, and the handle drives the fore shaft of cardboard when upwards pulling and exposes the base, and the recess of cardboard offsets the locking with the bump of setting element opposite side, and the chimb of cardboard inserts the spacing hole of setting element simultaneously, and the pothook of cardboard offsets the locking with the second pin department external diameter of cardboard.

One end of the slotted opening of the positioning piece extends forwards, the handle drives the locking opening of the clamping plate to expose out of the base when pulled upwards, and the slotted opening of the positioning piece exposes out of the front of the locking opening of the clamping plate; when the fore shaft of the clamping plate is pressed into the door frame 12, the door frame drives the positioning piece at the fore shaft to rotate inwards, and the groove of the clamping plate is separated from the convex point of the positioning piece. One side of base is equipped with screw platform 802, and the bottom of screw platform and the spacing limit parallel and level of base both sides are equipped with gasket 10 and anticreep screw 11 at the top of screw platform, and base one side of screw platform below is equipped with the mounting hole. The base upwards is T font arrow point, and the T font arrow point end bottom border of base aligns with the screw platform, and the fore shaft part of cardboard stretches out the T font arrow point end bottom border of base. The holding section of the handle is protruded towards the other end of the screw platform, the holding section of the self-locking section of the handle is symmetrical to the other end of the screw platform and is provided with a raised tail, the inclined plane at the tail end of the tail is provided with a rectangular groove, and a handle groove is formed between the self-locking section of the handle and the tail.

When the locking state is realized, the groove of the clamping plate is separated from the salient point of the positioning piece, as shown in figure 3; when the handle needs to be opened, the clamping plate can move together with the first pin when the handle is lifted upwards, after the handle is lifted by a certain angle, the torsion spring can drive the positioning piece to move, the salient point at the other end of the positioning piece can upwards enter the groove of the clamping plate, so that the handle cannot move downwards, and the self-locking function is achieved, as shown in fig. 6. The handle is held to push the pulling aid to a doorframe or other objects of the cabinet, when the doorframe or other objects of the cabinet first collide with the positioning piece, the head of the positioning piece retracts into the pulling aid, so that the convex point at the other end of the positioning piece is driven to be separated from the groove of the clamping plate; at this time, the handle angle can be freely pulled, and the function of automatically unlocking the wrench is completed, as shown in fig. 5.

Above-mentioned handle and base, the cardboard is connected, the cardboard also can move along with the cooperation of pin when the handle upwards lifts, reach the another of slide opening when the pin, the cardboard just in time reaches 45 jiaos, the torsional spring can resume natural state along with the cardboard from torsional state, the tip of torsional spring can be bounced the setting element and make its rotation down under the natural state, the bump of the setting element other end can make progress just in time block in the recess in the cardboard, make the unable downstream of handle, self-locking function has been reached. When the end part of the door frame touching the positioning piece rotates upwards, the salient point at the other end moves downwards to enable the salient point to leave the groove position on the clamping plate, and the handle is pressed down to enable the door frame to move normally.

The main advantages of the extraction aid are as follows: 1. when the handle of the pulling aid is lifted, the clamping plate is driven to move together by the pin, the torsion spring on the clamping plate is connected with the positioning piece, and after the clamping plate is lifted by a certain angle, the groove of the clamping plate touches the convex point of the positioning piece to achieve the self-locking function; when needing the unblock, as long as door frame or other objects touch the setting element and just can automatic unblock, the locking function that lifts up of current helps pulling out the ware needs to realize through more part and complicated inner structure, should help pulling out the ware and adopt less spare part and simple structure to realize, all parts all can mould the production, and the cost is lower. 2. Through the structural design of the pulling aid, the step that the existing pulling aid needs to manually operate a button to unlock and reuse is solved, the experience feeling and the efficiency of an operator are greatly facilitated, and the self-locking and touch automatic unlocking of the pulling aid are effectively realized.

In conclusion, the handle of the pulling aid is lifted for self-locking, and automatic unlocking is formed by impact when the pulling aid is used, namely the pulling aid has the functions of lifting the handle for automatic self-locking positioning and automatic unlocking positioning when the pulling aid is used; the positioning piece is the key point of the whole patent, and the positioning piece is needed when the pulling-assistant device is automatically unlocked by self-locking and impact.
