Technical Field

[0001] The utility model belongs to the field of door handles and relates to a hand-held unlocking type handle. Technical Background

[0002] For traditional door handles to open the door, it is necessary to pull the handle to rotate the bolt on the handle to unlock and then open the door. However, in the long-term use of this method, since the reset part of the door handle is a torsion spring, the torsion spring will age and rust over time, resulting in the situation that the reset is not in place. At this time, the door handle cannot maintain a horizontal state but shows a slightly downward inclination. Summary of the Invention

[0003] According to the above problems, the present invention provides a hand-held unlocking type handle. The device can be unlocked without pulling the handle, and the handle will not incline downward during long-term use.

[0004] The purpose of the present invention is achieved as follows:

A driving inclined groove matching the linkage shaft is formed on one side of the unlocking part opposite to the linkage groove. The linkage shaft is arranged in the driving inclined groove. A bolt groove corresponding to the bolt opening is formed on the unlocking part. A bolt is arranged in the bolt groove.

[0006] With the above settings, as long as the grip-opening part is held by hand and the grip-opening part is squeezed into the installation cavity, the linkage shaft on the grip-opening part is driven to move. Since the linkage shaft is arranged in the driving inclined groove of the unlocking part, the movement of the linkage shaft drives the unlocking part to rotate, and the bolt on the unlocking part rotates to unlock and open the door. In this way, it is not necessary to pull the handle to unlock the door, and the handle will not incline downward during long-term use.

[0007] The present invention is further arranged as: the handle part and the unlocking part form an "L"-shaped handle, and the bolt opening is arranged at one end of the unlocking part far from the handle part.

[0008] The present invention is further arranged as: the reset device includes a spring arranged in the grip-opening part installation cavity. The spring abuts between the handle part and the grip-opening part and drives the end of the grip-opening part close to the unlocking part to rotate out of the installation cavity.

[0009] Through the arrangement of the spring, after the squeezing grip-opening member unlocks, the spring resets the grip-opening member, facilitating unlocking next time and thus achieving the effect of repeated use.

[0010] The present invention is further configured such that: a spring post is formed in the grip-opening member installation cavity, and the spring is sleeved on the spring post.

[0011] Through the arrangement of the spring post, the spring can be stabilized, making the reset more stable.

[0012] The present invention is further configured such that: a fixing shell is provided at one end of the unlocking portion where the pin opening is formed, a connection hole for the unlocking portion to insert is formed on the fixing shell, a clamping groove is formed on the unlocking portion, and a clamping plate matching the clamping groove is arranged in the fixing shell.

[0013] The present invention is further configured such that: a fixing groove is formed on the unlocking portion, and a fixing block matching the fixing groove is formed on the connection hole.

[0014] Through the arrangement of the fixing groove and the fixing block, a better anti-tilting effect on the handle can be achieved.

[0015] The present invention is further configured such that: one end of the linkage groove close to the pin opening is a reset limiting end, and one end of the linkage groove far from the pin opening is an unlocking limiting end.

[0016] Through the arrangement of the reset limiting end, the reset distance of the grip-opening member can be controlled.

[0017] The present invention is further configured such that: a hinge hole is formed at one end of the grip-opening member away from the unlocking portion, a hinge seat is formed in the grip-opening member installation cavity, and a hinge shaft is arranged on the hinge seat and passes through the hinge hole to achieve rotational connection.

[0018] The present invention is further configured such that: the hinge seat is divided into two parts, one part is fixed in the grip-opening member installation cavity, and one part is arranged on the fixing cover, and the fixing cover is connected to the handle portion through fasteners.

[0019] Through the design that the hinge seat is composed of two parts, the disassembly, installation and maintenance of the hinge can be more convenient.

[0020] The present invention is further configured such that: a screw post is formed in the grip-opening member installation cavity, and the screw post passes through the grip-opening member and is fixedly connected to the fastener on the fixing cover.

[0021] The prominent and beneficial technical effects of the present invention compared with the prior art are as follows: As long as the user holds the grip-opening member and squeezes it into the installation cavity, the linkage shaft on the grip-opening member will be driven to move. Since the linkage shaft is arranged in the driving inclined groove of the unlocking member, the movement of the linkage shaft drives the unlocking member to rotate, and the bolt on the unlocking member rotates to achieve unlocking and opening the door. In this way, there is no need to turn the handle to unlock the door, and the handle will not tilt downward after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
