[0003] The strength of the lock tongue directly affects the safety performance of the lock. For the traditional lock tongue (such as Figure 1 ), the longitudinal section is generally square, which may be bent when the stress is several hundred Newton, which will affect the use effect and safety of the lock. The insufficient strength of the traditional lock tongue may cause the lock to be easily pried open or damaged after a certain use time, which may pose a potential threat to the user or affect the user's perception of the lock manufacturer.
[0004] Therefore, how to solve the problem of insufficient strength of the traditional lock tongue existing in the prior art has become the subject to be studied and solved by the utility model. INVENTION CONTENTS
[0005] The utility model aims at providing a high strength lock tongue adjusting assembly.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the technical scheme of:
[0007] The high strength lock tongue adjusting assembly comprises a fixed part, a lock tongue and an adjusting nut which are sequentially arranged on a lock rod in a first direction, and the lock rod is provided with a thread;
[0008] The lock tongue comprises a sleeving part and a main body part which are connected, the sleeving part is used for connecting with the lock rod, and at least part of the edge of the cross section of the main body part is curved in the first direction;
[0009] The high strength lock tongue adjusting assembly has an installation state, in which the first direction is parallel to the extension direction of the lock rod, and one end of the fixed part is fixedly sleeved outside the lock rod;
[0010] The sleeving part is axially movable and circumferentially limited to be sleeved outside the lock rod;
[0011] The adjusting nut is threadedly connected with the lock rod, and the adjusting nut can drive the lock tongue to move relative to the lock rod in a second direction to adjust the relative position of the lock tongue and the lock rod; the second direction is opposite to the first direction;
[0012] One end of the fixed part acts on the lock rod, the other end of the fixed part acts on the lock tongue, and the fixed part always has a force in the first direction to cooperate with the adjusting nut to clamp and fix the lock tongue from both sides.
[0013] In the above scheme, when adjusting the position of the lock tongue, the adjusting nut is rotated, the adjusting nut moves along the extension direction of the lock rod, the adjusting nut can provide a force in the second direction to the lock tongue, and the fixed part can provide a force in the first direction to the lock tongue, thereby the lock tongue can be adjusted in both directions along the extension direction of the lock rod to realize the alignment of the lock tongue and the lock hole, and the lock tongue can also be fixed.
[0014] When adjusting the position of the lock tongue, only the adjusting nut needs to be operated, so the adjustment process is simple and fast.
[0015] In the above structures, the adjusting nut and the lock tongue can be separated from the lock rod, and the fixed part can also be separated from the lock rod in some cases, so that the adjusting nut and other structures can be repeatedly disassembled and reused.
[0016] The cross section of the traditional lock tongue is generally square, especially rectangular, and correspondingly, the edges of the cross section of the traditional lock tongue are composed of four straight lines. In this application, the cross section of the lock tongue is not square, wherein at least part of the edges of the cross section of the main part is curved. Based on this, the cross section shape of the main part is changed compared to the traditional lock tongue. This change enables the lock tongue in this application to more effectively disperse stress when under stress, thereby improving the carrying capacity of the lock tongue.
[0017] Further technical solutions, along the first direction, the cross section of the main part is U-shaped.
[0018] This embodiment provides one of the specific settings of the lock tongue. By setting the cross section of the main part to be U-shaped, the cross section shape is more complex compared to the cross section shape of the traditional lock tongue. The U-shaped cross section can more effectively disperse stress compared to the square cross section, thereby improving the carrying capacity of the lock tongue.
[0019] Alternatively, the cross section of the main part can also be in the shape of an ellipse or the like.
[0020] Further technical solutions, along the third direction, the top end part of the edge of the cross section of the main part is a straight line, and the bottom end part of the edge of the cross section of the main part is curved.
[0021] This embodiment provides another specific setting of the lock tongue. In this case, the main part has multiple options, for example, in one case, the top surface of the main part is a plane, and the bottom surface is a curved surface. At this time, the cross section of the main part is in the shape of a half-ellipse or a half-circle.
[0022] It should be noted that the bottom end of the edge of the cross section of the main part is curved, at this time, the bottom end of the edge of the cross section of the main part can only consist of a single arc, or can consist of multiple arcs.
[0023] In a further technical solution, the top end of the edge of the cross section of the main part comprises at least one arc in the third direction, and the bottom end of the edge of the cross section of the main part is curved.
[0024] In a further technical solution, the fixing part comprises an elastic member, one end of the elastic member acts on the lock rod, and the other end of the elastic member acts on the lock tongue.
[0025] The elastic member always has an elastic force in the first direction to cooperate with the adjusting nut to clamp and fix the lock tongue from both sides.
[0026] When the lock tongue is placed transversely, the adjusting nut can only drive the lock tongue to move in one direction, and through the cooperation of the adjusting nut and the elastic member, since the forces of the two structures on the lock tongue are opposite, the position of the lock tongue can be adjusted in both directions along the extension direction of the lock rod.
[0027] In a further technical solution, the fixing part further comprises a gasket, and one end of the elastic member acts on the lock rod through the gasket.
[0028] In a further technical solution, at least one protruding member is arranged on the side surface of the lock tongue close to the adjusting nut, and at least one recessed member is arranged on the side surface of the adjusting nut close to the lock tongue.
[0029] Alternatively, at least one recessed member is arranged on the side surface of the lock tongue close to the adjusting nut, and at least one protruding member is arranged on the side surface of the adjusting nut close to the lock tongue.
[0030] Taking the lock tongue close to the side surface of the adjusting nut as an example, at least one protruding member is arranged on the side surface of the adjusting nut close to the lock tongue, and at least one recessed member is arranged on the side surface of the adjusting nut close to the lock tongue. Here, the protruding member is a single protruding point, and the recessed member is multiple and arranged as grooves. Initially, the protruding point is inserted into one of the grooves. When the adjusting nut is rotated, the protruding point is separated from the groove. If the rotation time of the adjusting nut is long enough, the protruding point will be sequentially inserted into each groove. When the protruding point leaves the groove, a sound will generally be emitted, which can be used to determine the adjustment amount of the adjusting nut and the axial movement amount of the lock tongue.
[0031] In a further technical solution, the protruding member is arranged as a protruding point, and / or the recessed member is arranged as a groove. The protruding point can be arranged as a semi-cylindrical body or a semi-elliptical structure. The cross section of the groove can be semi-circular or semi-elliptical.
[0032] Further, the lock tongue is made of metal material.
[0033] Further, the adjusting nut is made of metal material.

[0059] The high-strength lock tongue adjusting assembly has an installed state, in the installed state, the first direction is parallel to the extension direction of the lock rod 1, and one end of the fixed part 2 is fixedly sleeved outside the lock rod 1;
[0060] In the installed state, the sleeving part 31 is axially movably and circumferentially limitingly sleeved outside the lock rod 1;
[0061] In the installed state, the adjusting nut 4 is threadedly connected with the lock rod 1, and the adjusting nut 4 can drive the lock tongue 3 to move relative to the lock rod 1 along a second direction to adjust the relative position of the lock tongue 3 and the lock rod 1; the second direction is opposite to the first direction;
[0062] In the installed state, one end of the fixed part 2 acts on the lock rod 1, the other end of the fixed part 2 acts on the lock tongue 3, and the fixed part 2 always has an acting force towards the first direction to cooperate with the adjusting nut 4 to clampingly fix the lock tongue 3 from both sides.
[0063] In use, the first direction is generally parallel to the horizontal direction. The first direction is the A direction in the figure, the second direction is the B direction in the figure, and the third direction is the C direction in the figure. Figure 12 Figure 12 The first direction is parallel to the extension direction of the lock rod 1 and the second direction, and the first direction is perpendicular to the third direction.

[0064]
[0065] When the position of the locking tongue 3 is adjusted, since only the adjusting nut 4 needs to be operated, the adjusting process is simple and fast.
[0066] In the above structures, the adjusting nut 4 and the locking tongue 3 can be separated from the lock rod 1, and the fixing part 2 can also be separated from the lock rod 1 in some cases according to specific settings, so that the adjusting nut 4 and other structures can be repeatedly disassembled and assembled for repeated use.
[0067] For the locking tongue 3, the sleeving part 31 can be regarded as a connecting structure, and optionally, the sleeving part 31 is provided with a through hole for the lock rod 1 to pass through, and the cross section of the through hole is approximately square; the main body part 32 can be regarded as a locking structure, and the main body part 32 is used for being inserted into a lock hole for locking.
[0068] The cross section of the conventional locking tongue 3 is generally square (such as Figure 1 , Figure 2 ), especially rectangular, and correspondingly, the edges of the cross section of the conventional locking tongue 3 are composed of four straight lines. In the present application, the cross section of the locking tongue 3 is not square, and at least part of the edges of the cross section of the main body part 32 is curvedly arranged. Based on this, the cross section shape of the main body part 32 is changed compared with the conventional locking tongue 3. This change enables the locking tongue 3 in the present application to more effectively disperse stress when stressed, thereby improving the carrying capacity of the locking tongue 3.
[0069] It should be noted that along the first direction, at least part of the edges of the cross section of the main body part 32 is curvedly arranged, at this time, the plane where the cross section of the main body part 32 is located is parallel to the plane where the first direction is located and perpendicular to the plane where the third direction is located.
[0070] Referring to Figure 9 , in the present embodiment, along the first direction, the cross section of the main body part 32 is U-shaped.
[0071] The present embodiment provides one of the situations in which the locking tongue 3 is specifically arranged. By arranging the cross section of the main body part 32 to be U-shaped, correspondingly, compared with the cross section shape of the conventional locking tongue 3, the cross section shape is complicated, and the U-shaped cross section can more effectively disperse stress compared with the square cross section, thereby improving the carrying capacity of the locking tongue 3.
[0072] Optionally, the cross section of the main body part 32 can also be in the shape of an ellipse or the like.
[0073] Referring to Figure 8 , in the present embodiment, along the third direction, the top end part of the edges of the cross section of the main body part 32 is a straight line, and the bottom end part of the edges of the cross section of the main body part 32 is curvedly arranged.
[0074] The third direction is the C direction in Figure 12 .
[0075] Figure 8The locking tongue 3 in the middle can be set to a flat locking tongue 3.
[0076] This embodiment provides another specific configuration of the locking tongue 3. In this case, the main body 32 has multiple options. For example, in one case, the top surface of the main body 32 is a plane, while the bottom surface is a curved surface. In this case, the cross-section of the main body 32 is semi-elliptical or semi-circular.
[0077] It should be noted that the bottom part of the edge of the cross-section of the main body 32 is curved. In this case, the bottom part of the edge of the cross-section of the main body 32 can be composed of a single arc or multiple connected arcs.
[0078] It should also be noted that, in this embodiment, the top portion and the bottom portion are... Figure 8 The perspective in the text is used as a reference; for ease of understanding, the sleeve structure will be used as an example here. For the sleeve structure, the end away from the adjusting nut 4 is the top part and the end close to the adjusting nut 4 is the bottom part; the following explanation of the top and bottom parts of the cross section is the same as the explanation here.
[0079] See Figure 10 , Figure 11 In this embodiment, along a third direction, the top edge of the cross-section of the main body portion 32 includes at least one arc, and the bottom edge of the cross-section of the main body portion 32 is curved.
[0080] Figure 10 The latch 3 in the middle can be set as a bent latch 3; Figure 11 The locking tongue 3 in the middle can be set as a high bending locking tongue 3, that is, the bending degree is greater than that of the bending locking tongue 3.
[0081] by Figure 10 The locking tongue 3 in the figure is illustrated as follows: the main body 32 includes a first bent segment, a second bent segment, and a straight segment connected in sequence. The first bent segment is connected to the sleeve part 31. The first bent segment and the second bent segment are roughly the same. Taking the first bent segment as an example, the first bent segment is bent along a third direction. The top part of the edge of the first bent segment includes at least one arc and the bottom part includes at least one arc. The first bent segment can be set as a tubular structure, that is, its outer wall is curved. Alternatively, the first bent segment can be set to have a top surface, a bottom surface, and two side surfaces. The top surface and the bottom surface are curved surfaces, and the two side surfaces are straight surfaces. For the straight segment, the top part of the edge of the straight segment is a straight line and the bottom part is divided into an arc or a diagonal line.
[0082] The cross-sectional shapes of the flat latch 3, the bent latch 3, and the high bent latch 3 are all different from those of the traditional latch 3, and their strength is higher than that of the traditional latch 3. The difference between the three types of latches 3 is the change in locking height.

[0086] When the lock tongue 3 is placed transversely, the adjusting nut 4 can only drive the lock tongue 3 to move in one direction, and through the cooperation of the adjusting nut 4 and the elastic member 21, because the forces of the two structures on the lock tongue 3 are opposite, the position of the lock tongue 3 can be adjusted in the extension direction of the lock rod 1.
[0087] When the lock tongue 3 is placed transversely, it is generally not threadedly connected with the lock rod 1, and the adjusting nut 4 can only limit the lock tongue 3 from moving towards the adjusting nut 4, and only through the cooperation of the elastic member 21 and the adjusting nut 4, the lock tongue 3 can be bidirectionally limited in the extension direction of the lock rod 1.
[0088] Referring to Figure 5 、 Figure 6 、 Figure 12 In the embodiment, the fixing part 2 further comprises a gasket 22, and one end of the elastic member 21 acts on the lock rod 1 through the gasket 22.
[0089] The gasket 22 can play a damping and buffering role, and the gasket 22 is conventionally provided and will not be described here.
[0090] Referring to Figure 3 、 Figure 4 、 Figure 7 In the embodiment, at least one protruding member 5 is arranged on the side surface of the lock tongue 3 close to the adjusting nut 4, and at least one recessed member 6 is arranged on the side surface of the adjusting nut 4 close to the lock tongue 3.
