DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0033] refer to Figures 1 to 13 ,like Figure 1As shown, this embodiment provides a safety handle lock for a door, comprising at least one handle assembly 3 and a lock body, wherein the lock body comprises a lock shell 2 mounted on the door and a lock tongue 5 capable of sliding in the lock shell 2 to achieve locking with the door, the lock shell 2 comprises a pair of cover shells 21 that are interlocked and connected and a side plate 22 connected to one side of the pair of cover shells 21, the side plate 22 is mounted on the door by screws, the lock tongue 5 is accommodated in a cavity formed by the pair of cover shells 21, the handle assembly 3 comprises a plate body 32 parallel to the door plate and a wrench 31 pivotally connected to a concave cavity 325 of the plate body 32 by a shaft rod 35, the wrench 31 is semicircular, which can reduce the processing area of ​​the handle assembly 3, thereby saving costs, and the concave cavity 325 is sunken to accommodate the wrench 31, The wrench 31 is linked with the lock tongue 5 without other transmission parts or linkage parts to realize the direct driving or locking effect of the lock tongue 5. An elastic part is arranged between the wrench 31 and the plate body 32 so that the wrench 31 can be reset. After the wrench 31 is reset, it is hidden in the concave cavity 325. The lock body includes the lock tongue 5, the locking member 6 and the lock core 7 connected in sequence. The lock core 7 can drive the locking member 6 to lock the lock tongue 5. The lock core 7 includes a rotating rod and a knob 73. The rotating rod is fixed in the plate body 32 through the fixing member 33. The knob 73 is sleeved on the rotating rod. A lever 311 is vertically arranged on the side of the wrench 31 close to the lock body. A guide hole 511 is opened on the lock tongue 5. The lever 311 can move in the guide hole 511 and drive the lock tongue 5 to move. In the prior art, due to the structural relationship between the lock body and the handle, the linkage between the handle and the lock tongue is often realized through a complex transmission structure and transmission relationship. Such a structure not only has high requirements on the manufacture, assembly and installation of the product, but also easily leads to product failure due to the complex structure. In this embodiment, the lever 311 fixedly arranged on the wrench 31 directly drives the lock tongue 5 to move, eliminating the transmission components and connecting parts, making the structure simple and easy to use. Figure 4 As shown, a mounting seat 313 is provided on the wrench 31, and the shaft 35 is provided in the mounting seat 313. A pair of hinge seats 322 for connecting the two ends of the shaft 35 are provided on the plate body 32. In the embodiment of the present application, the elastic member is preferably a torsion spring. The elastic member is provided so that when the wrench 31 is actuated, the lever 311 can be driven to link the lock tongue 5, and there is no need to add a linkage mechanism for linking the wrench 31 and the lock tongue 5 and a reset mechanism for driving the lock tongue 5 to reset. Therefore, it has the characteristics of convenient installation, low cost, and space saving.

[0034] In the present application embodiment, Figure 7 As shown, when there is only one handle assembly 3, the knob 73 is mounted on the first rotary rod 71, and the knob 73 can be used to open the door indoors. By turning the knob 73, the locking member 6 can be driven to move up and / or down, thereby locking and / or unlocking the lock tongue 5.

[0035] like Figure 2 , Figure 3 , Fig.12 and Fig.13 As shown, when there are two handle assemblies 3, the rotary rods include a first rotary rod 71 and a second rotary rod 72, and the first rotary rod 71 and the second rotary rod 72 are both fixed in the corresponding plate body 32 by the fixing member 33, and the first rotary rod 71 and the second rotary rod 72 are plugged together to achieve mutual fixation, and the knob 73 is sleeved on the second rotary rod 72. Specifically, the first rotary rod 71 is provided with a connecting arm 711 that can be squeezed and deformed, and the second rotary rod 72 is provided with a connecting sleeve 721, and the connecting arm 711 can be inserted into the connecting sleeve 721, so as to connect the first rotary rod 71 and the second rotary rod 72, and the knob 73 is connected to the connecting sleeve 721. The first rotary rod 71 / the second rotary rod 72 can be driven arbitrarily to rotate the knob 73, thereby driving the locking member 6 to make a corresponding movement. In addition, the two levers 311 both extend into the guide hole 511.

[0036] Among them, a pull ring 712 is hinged on the first rotary rod 71. The first rotary rod 71 can be rotated only by pulling up the pull ring 712. When the pull ring 712 is reset, it is parallel to the end face of the first rotary rod 71 and does not protrude from the end face of the first rotary rod 71. The overall length of the rotary rod can be reduced, so that the lock core 7 can be suitable for use with thinner door panels.

[0037] Preferably, the knob 73 has a first stop block 731 and a second stop block 732 distributed at a certain angle. Correspondingly, the locking member 6 is provided with a blocking portion 61 and a limiting portion 62. The first stop block 731 abuts against the blocking portion 61 to drive the locking member 6 to move downward, so that the limiting portion 62 is away from the lock tongue 5. At this time, the lock tongue 5 as a whole can slide horizontally. The second stop block 732 abuts against the blocking portion 61 to drive the locking member 6 to move upward, so that the limiting portion 62 is close to the rear end of the lock tongue 5. At this time, the limiting portion 62 can limit the retreat of the lock tongue 5, thereby realizing the function of anti-locking.

[0038] like Figure 4 , Figure 6 and Fig. 9 As shown, a mounting hole 323 is provided on the plate body 32, and the fixing member 33 is installed in the corresponding mounting hole 323 by means of a screw 34. This design makes it easy to install the fixing member 33. A receiving hole 212 is provided on the cover shell 21, and the first rotating rod 71 and the second rotating rod 72 pass through the corresponding receiving hole 212 and are plugged into each other.

[0039] Preferably, at least two mutually spaced first screw holes 324 are arranged on the periphery of the mounting hole 323, and at least two mutually spaced second screw holes 331 are arranged on the fixing member 33. The screw 34 can be locked between the first screw hole 324 and the second screw hole 331, thereby realizing the fixed installation of the fixing member 33 and the plate body 32.

[0040] like Figure 4 and Figure 6As shown, the sinking direction of the mounting hole 323 is opposite to that of the cavity 325, which avoids excessive increase in the thickness of the plate body 32, and the plate body 32 is integrally formed, which also simplifies the processing technology.

[0041] like Figure 4 and Figure 5 As shown, a hidden hole 312 is provided on the wrench 31 for accommodating the end of the first rotary rod 71 / the end of the second rotary rod 72, so that the end surface of the first rotary rod 71 / the second rotary rod 72 does not protrude from the outer surface of the wrench 31, thereby reducing the risk of accidental contact.

[0042] like Figure 5 and Fig. 9 As shown, the wrench 31 is provided with a lever 311 perpendicular thereto, and the lever 311 is connected to the driving portion 51 of the lock tongue 5. When the wrench 31 is rotated, the lever 311 drives the lock tongue 5 to move, so that the lock tongue 5 is extended to lock and / or retracted to unlock. In order to ensure that the wrench 31 is released safely and smoothly, a limit block 326 is provided on the plate body 32 to limit the wrench 31. When the wrench 31 is released and reset, the wrench 31 contacts the limit block.

[0043] For ease of installation and use, the cover shell 21 is provided with a first through hole 211 , and the plate body 32 is provided with a second through hole 321 . The first through hole 211 and the second through hole 321 are located in corresponding positions, and are both used to allow the lever 311 to pass through.

[0044] like Fig.10 and Fig.11 As shown, the lock tongue 5 also includes a shoulder 52 and a tongue body 53. The toggle portion 51, the shoulder 52 and the tongue body 53 are integrally connected. A guide hole 511 is provided on the toggle portion 51. The toggle rod 311 can move in the guide hole 511. In order for the tongue body 53 to pass through, a through hole 221 is provided on the side panel 22 for allowing the tongue body 53 to pass through.

[0045] like Figure 8 , Fig.10 and Fig.11 As shown, a cover body 8 is sleeved on the tongue body 53. By designing the cover body 8 and the lock tongue 5 separately, different materials can be selected for the lock tongue 5 and the cover body 8. The cover body 8 is made of a material with high strength and not easy to deform or corrode, which can reduce the production cost while improving the overall pressure resistance and deformation resistance, thereby increasing the service life. At the same time, it is also convenient for the maintenance of wearing parts and reduces costs.

[0046] In the embodiment of the present application, a receiving groove 81 for inserting the tongue 53 is provided in the cover 8, and at least one card slot 82 is provided on the receiving groove 81, and at least one elastic card 531 is provided on the tongue 53. By engaging the elastic card 531 with the corresponding card slot 82, the tongue 53 and the cover 8 can be quickly installed and removed, thereby simplifying the installation process. In addition, the provision of the receiving groove 81 can avoid increasing the overall thickness of the lock body, and the shoulder 52 and the cover 8 are offset, which not only improves the accuracy of positioning when the two are installed, but also can share the impact force between the lock tongue 5 and the door frame of the door, thereby improving the service life; in addition, at least two pin holes that penetrate the receiving groove 81 are provided on the cover 8, and pins are installed in the pin holes, and the other end of the pin is connected to the tongue 53, which can further improve the connection reliability between the lock tongue 5 and the cover 8.

[0047] The usage process is as follows: first, the handle lock is unlocked by inserting the key into the lock cylinder 7, and then the user pulls the wrench 31 outward by hand, the wrench 31 drives the shaft rod 35 to rotate, the lever 311 and the wrench 31 move outward and backward, and then drives the lock tongue 5 to retreat as a whole, so that the lock tongue 5 is retracted into the lock shell 2 to realize the opening of the door lock, that is, the door is opened. After opening, the user releases the wrench 31, and the torsion spring drives the wrench 31 to reset, so that the lock tongue 5 is extended forward again to reset. When reverse locking is realized, the lock tongue 5 is in an extended state, and the knob 73 is rotated counterclockwise to drive the locking member 6 to move up, and the locking member 6 is blocked at the rear side of the lock tongue 5, thereby realizing reverse locking. When unlocking, the knob 73 is rotated clockwise to move the locking member 6 down.

[0048] The lock body 32 is convenient to use and can be easily installed with the lock body 32 inserted in the lock sleeve 32. The lock body 32 is convenient to install and can be easily installed with the lock sleeve 32 inserted in the lock sleeve 32. The defect of setting a connecting component between the door and the cover 21 is eliminated, and the space is further saved. The knob 73 is sleeved on the connecting sleeve 721 and contained in the cover 21, and the position of the knob 73 can be fixed, so that the knob 72 is installed securely; the lever 311 is set to be integrated with the wrench 31. When the wrench 31 is actuated, the lever 311 and the lock tongue 5 are linked to realize the opening of the door lock. In addition, the length of the lever 311 can determine the overall thickness of the door lock, so that the present application can also be applied to thin door panels, and the wrench 31 and the lever 311 can cooperate to realize the driving of the lock tongue 5. Therefore, the structure is simple and the cost is low. It also simplifies the overall structure of the door lock and reduces the occurrence of faults in use. Through the cooperation of the locking member 6 and the lock core 7, the backward restriction or release of the lock tongue 5 can be realized, thereby realizing reverse locking and unlocking. In summary, the present application has the characteristics of convenient and reliable installation, simplified structure, low fault incidence, and safe use.

[0049] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the embodiments of the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
