[0037] In view of the problem that the conventional guard assembly in the prior art has a complex structure of the emergency unlocking assembly, the utility model proposes a handle assembly.

[0038] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] In this embodiment, a handle assembly is disclosed. Figure 1 The entire three-dimensional structure of the handle assembly is shown. Figure 2 A perspective cutaway view of the handle assembly is shown. Figure 3 The assembly structure of the mounting seat, locking block, lever and unlocking lever involved in the handle assembly is shown. Figure 4 The figure shows the structure of the locking block involved in the handle assembly. Figure 5 The structure of the spacer involved in the handle assembly is shown.

[0040] Please refer to Figures 1 to 5The handle assembly in the utility model includes: two handles 1, a mounting seat 2, a square core 3, a reverse locking assembly 4 and an emergency unlocking assembly 5. Generally, at least one mounting seat 2 is installed. In this embodiment, two handles 1 are respectively provided with a mounting seat 2, and the square core 3 is inserted between the two handles 1. The reverse locking assembly 4 is arranged on one side of any one of the handles 1, and the emergency unlocking assembly 5 is arranged in the square core 3; wherein, the mounting seat 2 is attached to the door leaf, and the mounting seat 2 is used to fix the handle 1 on the door leaf; the square core 3 is used to form an effective connection with the closing mechanism of the lock unit inserted into the door leaf; the reverse locking assembly 4 is arranged on one side of the door, and is used to lock the handle 1; the emergency unlocking assembly 5 includes: an unlocking hole 51 and an unlocking rod 52; wherein, the unlocking hole 51 is arranged on the handle 1 and is communicated with the neck portion 111 of the handle; the unlocking rod 52 is arranged in the square core 3 and is connected to the anti-locking component 4; wherein, in the normal state, the unlocking rod 52 moves along the square core 3 driven by the anti-locking component 4; in the anti-locking state, the unlocking rod 52 is close to one side of the unlocking hole 51, and an unlocking tool that can pass through the unlocking hole 51 is used, and then the unlocking rod 52 is pushed to move on the side of the square core away from the unlocking hole 51, so as to move the anti-locking component 4 and complete the emergency unlocking, so that when the anti-locking is mistaken or there is a safety problem, the anti-locking state of the handle assembly can be released from the outside of the door.

[0041] Secondly, the handle 1 includes: an inner handle 11 and an outer handle 12; wherein the inner handle 11 and the outer handle 12 are respectively inserted at the two ends of the square core 3; the axial neck portion 111 of the inner handle 11 is rotatably arranged on the mounting seat 2. Both the inner handle 11 and the outer handle 12 can rotate relative to the mounting seat 2. When in use, the mounting seat 2 is fixedly installed on the door leaf or the lock, which can indirectly fix the two handles 1 so that the two handles 1 can rotate around the axis, and in this embodiment, the unlocking hole 52 is arranged on the outer handle 12 and communicates with the inside of the axial neck portion of the outer handle 12.

[0042] In this embodiment, a traditional L-shaped handle 1 is used. In other embodiments, handles 1 of other shapes such as spherical shapes can also be used, as long as the neck portions 111 of the inner and outer handles 12 can be provided with sufficient cavities to accommodate the square core 3 and the emergency unlocking assembly 5.

[0043] Secondly, the anti-locking assembly 4 comprises: a locking block 41, a groove 42 arranged at one end of the locking block 41, and a protrusion 21 arranged at one side of the mounting seat 2 and opposite to the groove 42, wherein an arc groove 114 opposite to the protrusion 21 is provided at the end of the shaft neck 111; when the locking block 41 is not moved to the locking position, the inner handle 11 is rotated, and the protrusion 21 moves relatively in the arc groove 114, thereby realizing hiding the protrusion 21 in the handle 1, ensuring the beauty and simplicity of the handle 1. When the locking block 41 moves to the locking position, the protrusion 21 is embedded in the groove 42, and the protrusion 21 prevents the groove 42 from rotating, thereby preventing the inner handle 11 from rotating around the axis. When the rotational freedom of the inner handle 11 is restricted, the freedom of the outer handle 12 opposite thereto is also restricted, thereby realizing the anti-locking function of the handle 1 assembly, and the structure of the combination of the groove 42 and the protrusion 21 is simple, and the trial range is wide, meeting more needs.

[0044] Secondly, a sliding cavity 112 is axially provided in the side wall of the shaft neck 111, and the locking block 41 is slidably assembled in the sliding cavity 112. Secondly, a sliding hole 113 penetrating the side wall is formed on the sliding cavity 112, and a lever 43 is slidably assembled in the sliding hole 113, one end of the lever 43 is arranged outside the sliding hole 113, and the other end is connected to the locking block 41. The user can drive the locking block 41 to move by shifting the lever 43 outside the sliding hole 113, so as to realize the reverse locking of the handle 1.

[0045] Secondly, one end of the unlocking rod 52 is fixed to the lower end of the locking block 41. The unlocking rod 52 can be driven to move in the square core 3 by turning the locking block 41. The unlocking rod 52 can also be driven to move in the sliding cavity 112 by pushing the unlocking rod 52 to achieve emergency unlocking. The size of the unlocking hole 51 can be adjusted according to the size and shape of the handle 1 to meet the needs of different situations. When the door is accidentally locked, a rod can be inserted into the unlocking hole 51 to push the unlocking rod 52 to move in the square core 3. The unlocking rod 52 pushes the locking block 41 to slide and unlock, achieving emergency unlocking. The rod can be a toothpick or a silver needle or other daily necessities, which can be slender and have a certain hardness.

[0046] Secondly, a spacer 6 is provided on the handle 1, and the spacer 6 is used to reduce wear. The spacer 6 includes: a washer 61 provided between the inner handle 11 and the mounting seat 2, and a pad 62 provided between the locking block 41 and the shaft neck 111. The pad 62 is provided on the side of the locking block 41 close to the axis. The washer 61 and the pad 62 are an integrated structure. When the handle 1 rotates, friction will be generated between the handle 1 and the mounting seat 2, and the locking block 41 will also generate friction with the side wall of the sliding cavity 112 when sliding. The use of the spacer 6 can effectively reduce the friction between the handle 1 and the mounting seat 2, and between the locking block 41 and the sliding cavity 112, thereby extending the service life, and can improve the feel of the handle 1 and the anti-locking assembly 4 during use.

[0047] To sum up, the locking block 41 is slidably locked with the mounting base 2 to achieve the locking of the door handle. Compared with the existing locking method, the structure of the anti-lock component 4 is simpler, more reliable, and not easy to be damaged; the anti-lock component 4 is arranged on the neck portion 111 of the handle 1 to make the surface of the handle 1 more concise and beautiful; the handle 1 is also provided with an emergency unlocking component 5. When an emergency situation such as accidental locking occurs in the door, a rod-shaped object can be inserted into the unlocking hole 51 to push the unlocking rod 52 so that the locking block 41 slides and unlocks, thereby realizing emergency unlocking, and the structure is simpler.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
