[0024] Example 1

[0025] like Figures 1 to 6 As shown, in this embodiment, a framed door is disclosed, which includes a door leaf 11, a door frame 12, and a door lock 10.

[0026] The door lock 10 includes a lock cylinder 21, a first handle 23, and a second handle 24. The first end of the lock cylinder 21 has an enlarged portion 211 extending outwards, within which a latch 22 slides. The latch 22 can extend outwards or retract into the lock cylinder 21 under the control of the handle, thereby achieving locking and unlocking. The first handle 23 includes a first handle base 232 and a first handle 231, with the first handle base 232 fixedly connected to one side of the lock cylinder 21. The second handle 24 has the same structure as the first handle 23, and the two are symmetrically arranged on the inner and outer sides of the lock cylinder 21. The specific internal structures of the lock cylinder 21, the first handle 23, and the second handle 24, as well as their connection relationships and operating methods, are existing technologies and not innovative aspects of this utility model; therefore, they will not be described in detail here.

[0027] A groove for accommodating the lock cylinder 21 is formed on one side of the door leaf 11 (not shown in the figure due to obstruction); the door frame 12 is fixed to the side of the door leaf 11, and a lock hole opposite to the latch 22 is formed on the door frame 12 (not shown in the figure due to obstruction). The lock cylinder 21 can enter the groove of the door leaf 11 through the lock hole from the outside of the door frame 12 until the enlarged part 211 abuts against the outside of the lock hole.

[0028] In this embodiment, the door lock 10 further includes a first cover 25, a second cover 26, a first connector 27, a second connector 28, a first fastener 31, a second fastener 32, a third fastener 33, and a fourth fastener 34.

[0029] The first connector 27 is located between the first cover 25 and the lock cylinder 21, and has a third hole 43 opposite to the first handle seat 232 and a fourth hole 44 opposite to the first hole 41. The second connector 28 is located between the second cover 26 and the lock cylinder 21, and has a fifth hole opposite to the second handle seat 24 and a sixth hole opposite to the second hole 42 (the fifth and sixth holes are not shown in the figure due to obstruction).

[0030] It should be noted that, in Figure 2 and Figure 3The diagram only shows the structure of the first handle 23 and its relationship with the lock cylinder 21. The structure of the second handle 24 and its relationship with the lock cylinder 21 on the other side is symmetrical to the corresponding structure in this diagram. Specifically, the structure of the second handle 24 is the same as that of the first handle 23, and they are symmetrical along the inside and outside of the door leaf 11; the structure of the second cover 26 is the same as that of the first cover 25, and they are symmetrical along the inside and outside of the door leaf 11; the structure of the second connector 28 is the same as that of the first connector 27, and they are symmetrical along the inside and outside of the door leaf 11; the structure of the third fastener 33 is the same as that of the first fastener 31, and they are symmetrical along the inside and outside of the door leaf 11; the structure of the fourth fastener 34 is the same as that of the second fastener 32, and they are symmetrical along the inside and outside of the door leaf 11; the structure of the second hole 42 is the same as that of the first hole 41, and they are symmetrical along the inside and outside of the door leaf 11; the structure of the fifth hole is the same as that of the third hole 43, and they are symmetrical along the inside and outside of the door leaf 11; the structure of the sixth hole is the same as that of the fourth hole 44, and they are symmetrical along the inside and outside of the door leaf 11.

[0031] The specific structures of the second handle 24, second cover 26, second connector 28, third fastener 33, fourth fastener 34, second hole 42, fifth hole, and sixth hole, which are not fully shown in the attached diagram, can be found by referring to the following references: Figure 2 and Figure 3 The specific structure of the first handle 23, the first cover 25, the first connector 27, the first fastener 31, the second fastener 32, the first hole 41, the third hole 43 and the fourth hole 44.

[0032] One end of the first fastener 31 passes through the third hole 43 and the first cover 25 and is connected to the first handle seat 232. The second fastener 32 is disposed in the first hole 41 and the fourth hole 44, connecting the first cover 25 and the first connector 27 together. One end of the third fastener 33 passes through the fifth hole and the second cover 26 and is connected to the second handle seat 24. The fourth fastener 34 is disposed in the second hole 42 and the sixth hole, connecting the second cover 26 and the second connector 28 together.

[0033] In this embodiment, when the door lock 10 is installed on a framed door, the lock cylinder 21 can be inserted from the lock hole of the door frame 12 into the groove in the door leaf 11. The enlarged portion 211 at the end of the lock cylinder 21 can abut against the outside of the door frame 12. The handle in the door lock 10 is fixedly connected to the lock cylinder 21, and two connecting pieces are fixedly connected to the handle. On the inside of the door frame 12, the first cover 25 and the second cover 26 can be tightly pressed against the inside of the door frame 12 by the second fastener 32 and the fourth fastener 34, and the covers and connecting pieces can be connected at the same time, thus finally fixing the door lock 10 to the door. Throughout the process, there is no need to drill bolt holes at the edge of the door leaf 11 to install and fix the door lock 10 to the framed door.

[0034] As one implementation method, in this embodiment, such as Figure 2 and Figure 3 As shown, the first connector 27 has a U-shaped structure with two third holes 43; the second connector 28 has a U-shaped structure with two fifth holes. This type of connector structure allows for a more stable connection with the handle seat, and also facilitates the bolts connecting the two handle seats to pass through the middle of the two connectors without interfering with the connection between the two handles.

[0035] As one implementation method, in this embodiment, such as Figure 2 and Figure 3 As shown, the first fastener 31 is a screw, and the first handle seat 232 has a screw hole 46 opposite to the third hole 43; the third fastener 33 is a screw, and the second handle seat 24 has a screw hole opposite to the fifth hole (not shown in the figure due to obstruction). The use of screws for these two fasteners facilitates quick connection of the first connector 27, the first cover 25, and the first handle 23, as well as quick connection of the second connector 28, the second cover 26, and the second handle 24.

[0036] As one implementation method, in this embodiment, such as Figure 2 and Figure 3 As shown, the second fastener 32 is a screw, and the fourth hole 44 is a screw hole; the fourth fastener 34 is a screw, and the sixth hole is a screw hole. The use of screws for these two fasteners allows installers to quickly and securely fasten the first cover 25 and the second cover 26 against the inside of the door frame 12.

[0037] It should be noted that when the first fastener 31 passes through the first cover 25 to connect the first connector 27 and the first handle seat 232, the first cover 25 is clamped between the first connector 27 and the first handle seat 232, and its displacement along its thickness direction is limited, but it can still move relative to the first connector 27 and the first handle seat 232 under the action of external force along its length. Therefore, when the installer tightens the second fastener 32, the second fastener 32 can push the first cover 25 to move inward toward the inside of the door frame 12 until the first cover 25 is pressed tightly against the inside of the door frame 12.

[0038] Similarly, the second cover 26 can also be pressed tightly against the inside of the door frame 12 by the action of the fourth fastener 34.

[0039] In other embodiments, the first fastener 31 to the fourth fastener 34 can also be connected to the corresponding holes by a snap-fit ​​method. For example, the first fastener 31 can be configured as a locking lever, with one end snapping into the hole on the first handle seat 232 opposite to the third hole 43; the second fastener 32 can be configured as a locking lever, with one end snapping into the fourth hole 44; the third fastener 33 can be configured as a locking lever, with one end snapping into the hole on the second handle seat 24 opposite to the fifth hole; and the fourth fastener 34 can be configured as a locking lever, with one end snapping into the sixth hole. Fasteners with this structure can also fix the door lock 10 to the framed door.

[0040] As one implementation method, in this embodiment, such as Figure 2 and Figure 3 As shown, the first cover 25 has a first elongated hole 45 opposite to the third hole 43 along the length direction of the second fastener 32; the second cover 26 has a second elongated hole opposite to the fifth hole along the length direction of the fourth fastener 34. These two elongated holes guide the first cover 25 and the second cover 26 to move towards one side of the door frame 12 when the installer uses the second fastener 32 and the fourth fastener 34 to press the first cover 25 and the second cover 26 tightly against the inner side of the door frame 12, preventing displacement in other directions. This speeds up installation and improves the stability of the door lock 10.

[0041] As one implementation method, in this embodiment, such as Figure 2 and Figure 3 As shown, the door lock 10 also includes a first bushing 29 and a second bushing 30, wherein the first bushing 29 is disposed between the first cover 25 and the lock cylinder 21; the second bushing 30 is disposed between the second cover 26 and the lock cylinder 21; wherein the first bushing 29 and the second bushing 30 are flexible structural components. By setting this flexible bushing, the connection between the two covers and the lock cylinder 21 can be made more stable, and the parts are less likely to loosen during subsequent use of the door lock 10.

[0042] The specific steps for installing the door lock 10 on the framed door in this embodiment are as follows: First, insert one end of the lock cylinder 21 into the groove of the door leaf 11 through the lock hole on the door frame 12 until the enlarged part 211 abuts against the outer side of the door frame 12; then connect the first connector 27, the first cover 25, and the first handle seat 232 together with the first fastener 31, and connect the second connector 27, the second cover 26, and the second handle 24 together with the third fastener 33; after fitting the first liner 29 and the second liner 30 onto both sides of the lock cylinder 21, then... The first handle 23 and the second handle 24 are fixed to both sides of the lock cylinder 11 by bolt clamping. At this time, the first cover 25 and the second cover 26 cover both sides of the lock cylinder 21. The second fastener 32 is inserted into the first hole 41 and the fourth hole 44, and the fourth fastener 34 is inserted into the second hole 42 and the sixth hole. The second fastener 32 and the fourth fastener 34 are tightened until the first cover 25 and the second cover 26 are pressed against the inner side of the door frame 12. The two covers are clamped and cooperated with the enlarged part 211, so that the door lock 10 can be fixedly installed on the framed door.

[0043] Example 2

[0044] In this embodiment, a framed door is disclosed, the structure of which can be referred to. Figure 1 and Figure 2 The framed door includes a door leaf 11, a door frame 12, and a door lock 10.

[0045] The door lock 10 includes a lock cylinder 21, a first handle 23, and a second handle 24. The first end of the lock cylinder 21 has an enlarged portion 211 extending outwards, within which a latch 22 slides. The latch 22 can extend outwards or retract into the lock cylinder 21 under the control of the handle, thereby achieving locking and unlocking. The first handle 23 includes a first handle base 232 and a first handle 231, with the first handle base 232 fixedly connected to one side of the lock cylinder 21. The second handle 24 has the same structure as the first handle 23, and the two are symmetrically arranged on the inner and outer sides of the lock cylinder 21. The specific internal structures of the lock cylinder 21, the first handle 23, and the second handle 24, as well as their connection relationships and operating methods, are existing technologies and not innovative aspects of this utility model; therefore, they will not be described in detail here.

[0046] A groove for accommodating the lock cylinder 21 is formed on one side of the door leaf 11; the door frame 12 is fixed to the side of the door leaf 11, and a lock hole opposite to the lock tongue 22 is formed on the door frame 12. The lock cylinder 21 can enter the groove of the door leaf 11 through the lock hole from the outside of the door frame 12 until the enlarged part 211 abuts against the outside of the lock hole.

[0047] The main difference between the door lock 10 in this embodiment and the door lock 10 in embodiment one is that, in this embodiment, after the second cover 26 and the first cover 25 are covered on the lock cylinder 21, they are directly connected together, for example, snapped together or bolted together. Therefore, if one cover is controlled to slide, the other cover will also slide along with it.

[0048] Therefore, the structure of the door lock 10 in this embodiment can also be referred to Figure 2 and Figure 3 Specifically, the door lock 10 also includes a first cover 25, a second cover 26, a first connector 27, a first fastener 31, and a second fastener 32. The first cover 25 is a semi-shell covering the first side of the lock cylinder 21, located between the first handle seat 232 and the lock cylinder 21, with a first hole 41 formed at its second end. The second cover 26 is a semi-shell covering the second side of the lock cylinder 21, located between the second handle seat 24 and the lock cylinder 21, and is connected to the first cover 25.

[0049] The first connector 27 is disposed between the first cover 25 and the lock cylinder 21, and has a third hole 43 opposite to the first handle seat 232 and a fourth hole 44 opposite to the first hole 41. One end of the first fastener 31 passes through the third hole 43 and the first cover 25 and is connected to the first handle seat 232. The second fastener 32 is disposed in the first hole 41 and the fourth hole 44, connecting the first cover 25 and the first connector 27 together.

[0050] In this embodiment, when the door lock 10 is installed on a framed door, the lock cylinder 21 can be inserted from the lock hole of the door frame 12 into the groove in the door leaf 11. The enlarged portion 211 at the end of the lock cylinder 21 can abut against the outside of the door frame 12. The handle in the door lock 10 is fixedly connected to the lock cylinder 21, and the first connecting member 27 is fixedly connected to the first handle seat 232. On the inside of the door frame 12, the first cover 25 and the second cover 26 can be tightly pressed against the inside of the door frame 12 by the second fastener 32, which can also connect the cover and the connecting member, thus finally fixing the door lock 10 to the door. Throughout the process, there is no need to drill bolt holes at the edge of the door leaf 11 to install and fix the door lock 10 to the framed door.

[0051] As one implementation method, in this embodiment, such as Figure 2 and Figure 3 As shown, the first fastener 31 is a screw, and the first handle seat 232 has a screw hole opposite to the third hole 43. The use of a screw as a fastener makes it easy for installers to quickly connect the first connector 27, the first cover 25, and the first handle 23 together.

[0052] As one implementation method, in this embodiment, such as Figure 2 and Figure 3 As shown, the first cover 25 has a first elongated hole 45 opposite to the third hole 43 along the length direction of the second fastener 32. When the installer presses the first cover 25 and the second cover 26 tightly against the inner side of the door frame 12 using the second fastener 32, the first elongated hole 45 can guide the first cover 25 and the second cover 26 to move towards one side of the door frame 12, preventing displacement in other directions. This speeds up the installation process and improves the stability of the door lock 10.

[0053] The specific steps for installing the door lock 10 on the framed door in this embodiment are as follows: First, insert one end of the lock cylinder 21 into the groove of the door leaf 11 through the lock hole on the door frame 12 until the enlarged part 211 abuts against the outer side of the door frame 12; then connect the first connector 27, the first cover 25, and the first handle seat 232 together with the first fastener 31; put the second cover 26 on the side of the lock cylinder 21 near the second handle 24, and then place the first handle 23 against the other side of the lock cylinder 21. After connecting the first cover 25 and the second cover 26 together, clamp and fix the first handle 23 and the second handle 24 to both sides of the lock cylinder 11 with bolts; insert the second fastener 32 into the first hole 41 and the fourth hole 44, and tighten the second fastener 32 until the first cover 25 and the second cover 26 abut against the inner side of the door frame 12. The two covers and the enlarged part 211 clamp and cooperate, and the door lock 10 can be fixedly installed on the framed door.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
