Description

Technical Field

[0001] The utility model relates to the technical field of batons, in particular to a telescopic baton. Background Art

[0002] The baton is a police device or personal protective weapon widely used by public security, special police and other law enforcement personnel. Its design includes a small tube, a middle tube, a large tube, a total of three tubes and a locking plate. The baton can be freely switched between the extended and retracted positions to achieve its freely retractable and changeable characteristics. The small tube is partially retracted into the large tube. When it is needed, the small tube can be extended from the large tube and firmly clamped to the inner surface of the larger tube through a locking mechanism, thereby maintaining the extended state of the baton. The locking mechanism usually consists of a first drum-disc locking plate and a second drum-disc locking plate, which are located at the ends of the small tube and the middle tube. The end of the first drum-disc locking plate contains a first through hole, and the end of the second drum-disc locking plate contains a second through hole. When the two drum-disc locking plates are combined together, the two through holes overlap and align so that the unlocking rod can pass through. For details, please refer to Figure 1 .

[0003] However, there is a potential problem in the existing design. During the locking process, if the first drum disc locking piece and the second drum disc locking piece are not properly aligned, the unlocking rod may first be inserted into the first through hole and then into the second through hole instead of inserting into both through holes at the same time. Figure 2 and Figure 3 As shown by the dotted line in .

[0004] In this case, the first drum disc lock piece and the second drum disc lock piece may not be able to completely clamp the unlocking rod, thereby reducing the reliability of the lock and increasing the possibility of wear. After long-term telescopic activities, the first drum disc lock piece and the second drum disc lock piece may be deformed or damaged, affecting the locking effect, resulting in poor telescopic baton extension and extension, and the baton getting stuck. There is room for improvement. Utility Model Content

[0006] The telescopic baton further comprises an unlocking rod, and the unlocking rod can move axially along the first tube body;

[0007] The telescopic baton further comprises at least one group of locking components, wherein the locking components comprises two locking blocks capable of radial extension and contraction, each of the two locking blocks having a semicircular hole, a limiting groove and a limiting protrusion, wherein the limiting groove, the semicircular hole and the limiting protrusion are sequentially arranged along the radial direction of extension and contraction; an unlocking channel is formed between the semicircular holes on the two locking blocks, and the limiting protrusion on one locking block is arranged in the limiting groove on the other locking block; at least two first springs are arranged between the two locking blocks, and the two first springs are arranged along a direction perpendicular to the radial direction of extension and contraction;

In the locked state, the first spring acts on the two locking blocks to move away from each other along the radial direction of the first tube body, so that the two locking blocks are locked in the first slot; in the unlocked state, the unlocking rod penetrates into the unlocking channel and synchronously drives the two locking blocks to move closer to each other and shrink inward along the radial direction of the first tube body, so that the two locking blocks are disengaged from the first slot and can slide axially along the first tube body.

[0009] In an embodiment of the present invention, in the locking assembly on the second tube body, the semicircular holes, the limiting grooves and the limiting protrusions on the two locking blocks are respectively arranged between the two first springs.

[0010] In one embodiment of the utility model, in the locking assembly on the second tube body, in one of the locking blocks, the locking block comprises a locking body and a locking extension section fixedly connected to the locking body, the locking extension section is in a semicircular arc shape to form a semicircular hole; a limiting groove is provided on the locking body, and a limiting protrusion is provided at one end of the locking extension section away from the limiting groove;

[0011] The two locking blocks are symmetrically arranged relative to the axis center of the first tube body; and two first springs are arranged between the two locking bodies.

[0012] In one embodiment of the utility model, a third tube body is further included, wherein the third tube body is nested inside the second tube body and can be axially retracted relative to the second tube body; a second clamping groove is provided on the inner wall of the second tube body;

[0013] The locking assembly is provided with at least two groups, and another group of locking assemblies is arranged at one end of the third tube body and at a relative position of the second slot; for the locking assembly on the third tube body, the locking assembly has a locked state and an unlocked state. In the locked state, the first spring acts on the two locking blocks to spread away from each other along the radial direction of the second tube body so that the two locking blocks are locked in the second slot; in the unlocked state, the unlocking rod penetrates into the unlocking channel and synchronously drives the two locking blocks to move closer to each other and shrink inward along the radial direction of the second tube body so that the two locking blocks are disengaged from the second slot and can slide axially along the second tube body.

[0014] In an embodiment of the present invention, the two locking blocks in the same group of the locking assemblies have the same configuration.

[0015] In an embodiment of the utility model, the shape of the limiting protrusion in the locking assembly of the same group away from the locking extension section is arched.

[0016] In an embodiment of the present invention, the locking body, the locking extension section and the limiting protrusion in the same group of the locking components are integrally formed.

[0017] In one embodiment of the utility model, an unlocking button is provided at the other end of the first tube body, the unlocking button can move axially along the first tube body, and the unlocking rod is fixedly connected to the unlocking button;

[0018] A second spring is arranged between at least one of the unlocking button or the unlocking rod and the inner wall of the first tube body.

[0019] In one embodiment of the utility model, two first slots are arranged on the inner wall of the first tube body, and in a locked state, a locking block of the locking assembly on the second tube body is locked in one of the first slots;

[0020] And / or, the inner wall of the second tube body is provided with two second slots, and in the locked state, a locking block in the locking assembly on the third tube body is locked in one of the second slots.

[0021] In one embodiment of the utility model, the first clamping groove is annular, and in a locked state, two locking blocks in the locking assembly on the second tube body are locked together in the annular first clamping groove;

[0022] And / or, the second clamping groove is annular, and in a locked state, the two locking blocks in the locking assembly on the third tube body are locked together in the annular second clamping groove.

[0023] In summary, the telescopic baton provided by the utility model has the following technical effects:

[0024] The two locking blocks in the locking assembly of the telescopic baton can move simultaneously, for example, approach each other or move away from each other at the same time. Therefore, when the unlocking rod penetrates the unlocking channel formed between the semicircular holes of the two locking blocks, the unlocking rod will act on the two locking blocks at the same time, and the two locking blocks will move away from each other without any time lag. At the same time, the two locking blocks are also respectively provided with a limiting groove and a limiting protrusion, and the limiting protrusion on one locking block is set in the limiting groove on the other locking block. It can be seen that the two locking blocks will specifically limit each other through the limiting groove and the limiting protrusion, so that the two locking blocks can only move horizontally in the radial direction without tilting, so as to solve the problem that the drum disc lock piece of the existing design deviates from the groove position, and can effectively compensate for the inward tilting of the existing disc when it is impacted. The sliding lock solves the structural defects of the locking piece of the mechanical baton. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] See also Figure 4-Figure 12 The embodiment of the utility model discloses a telescopic baton, which includes a first tube body 7 and a second tube body 8. The second tube body 8 is nested in the first tube body 7 and can be axially telescopic relative to the first tube body 7. A first slot 71 is provided on the inner wall of one end of the first tube body 7.

[0042] The telescopic baton further comprises an unlocking rod 9 which can move axially along the first tube body 7 .

[0043] The telescopic baton also includes at least one group of locking components, which include two locking blocks 6 that can be radially telescoped. The two locking blocks 6 each have a semicircular hole 61, a limiting groove 62 and a limiting protrusion 63, and the limiting groove 62, the semicircular hole 61 and the limiting protrusion 63 are arranged in sequence along the radial direction of telescope; an unlocking channel is formed between the semicircular holes 61 on the two locking blocks 6, and the limiting protrusion 63 on one locking block 6 is arranged in the limiting groove 62 on the other locking block 6; at least two first springs 66 are arranged between the two locking blocks 6, and the two first springs 66 are arranged in a direction perpendicular to the radial direction of telescope.

[0044] One group of locking components is arranged at one end of the second tube body 8 and at a relative position of the first slot 71; for the locking component on the second tube body 8, the locking component has a locked state and an unlocked state. In the locked state, the first spring 66 acts on the two locking blocks 6 to spread away from each other along the radial direction of the first tube body 7, so that the two locking blocks 6 are locked in the first slot 71; in the unlocked state, the unlocking rod 9 penetrates into the unlocking channel and synchronously drives the two locking blocks 6 to move closer to each other and shrink inward along the radial direction of the first tube body 7, so that the two locking blocks 6 are disengaged from the first slot 71 and can slide axially along the first tube body 7.

[0045] In the specific implementation process, the locking assembly on the second tube body 8 in the telescopic baton has two different states—a locked state and an unlocked state. Different forms of the telescopic baton can be switched in different states. For example, when the telescopic baton needs to be unfolded for use, the second tube body 8 can be extended from the first tube body 7, and the locking assembly provided on the second tube body 8 will also move axially synchronously until the locking assembly moves to the first slot 71 on the inner wall of the first tube body 7. Under the action of the two first springs 66, the two locking blocks 6 in the locking assembly are radially away from each other along the first tube body 7 and unfolded, so that the two locking blocks 6 are locked in the first slot 71. This is the locked state of the locking assembly. It can be seen that the second tube body 8 can be stably locked to the first tube body 7 through the locking assembly to form a stable unfolded state of the second tube body 8 and the first tube body 7.

[0046] For example, when the telescopic baton needs to be retracted, the unlocking rod 9 can be specifically driven to approach the locking assembly on the second tube body 8 until the unlocking rod 9 penetrates into the unlocking channel formed between the two locking blocks 6, and the two locking blocks 6 are synchronously driven to approach each other and retract along the radial direction of the first tube body 7, so that the two locking blocks 6 are disengaged from the first slot 71. At this time, the locking assembly can slide axially along the first tube body 7. This is an unlocked state, and the second tube body 8 can be retracted into the first tube body 7.

[0047] In summary, the two locking blocks 6 in the locking assembly of the telescopic baton can move simultaneously, for example, approach each other or move away from each other at the same time. Therefore, when the unlocking rod 9 penetrates the unlocking channel formed between the semicircular holes 61 of the two locking blocks 6, the unlocking rod 9 will act on the two locking blocks 6 at the same time, and the two locking blocks 6 will move away from each other without any time lag. At the same time, the two locking blocks 6 are also respectively provided with a limiting groove 62 and a limiting protrusion 63, and the limiting protrusion 63 on one locking block 6 is arranged in the limiting groove 62 on the other locking block 6. It can be known that the two locking blocks 6 will specifically limit each other through the limiting groove 62 and the limiting protrusion 63, so that the two locking blocks 6 can only move horizontally in the radial direction without tilting, so as to solve the problem that the drum disc lock plate of the existing design deviates from the groove position, and can effectively make up for the inward tilting slide lock of the existing disc when impacted, and solve the structural defects of the mechanical baton lock plate.

[0048] In an optional embodiment, in the locking assembly on the second tube 8, the semicircular holes 61, the limiting grooves 62 and the limiting protrusions 63 on the two locking blocks 6 are respectively arranged between the two first springs 66. Such an arrangement makes the entire locking assembly structure more compact, so as to ensure that the volume of the overall telescopic baton is better controlled.

[0049] In an optional embodiment, in the locking assembly on the second tube body 8, in one locking block 6, the locking block 6 includes a locking body 64 and a locking extension 65 fixedly connected to the locking body 64, the locking extension 65 is in a semicircular arc shape to form a semicircular hole 61; a limiting groove 62 is provided on the locking body 64, and a limiting protrusion 63 is provided at one end of the locking extension 65 away from the limiting groove 62; in the two locking blocks 6, the two locking blocks 6 are symmetrically arranged relative to the axis center of the first tube body 7; and two first springs 66 are arranged between the two locking bodies 64. In this way, when the telescopic baton needs to be unfolded for use, the second tube body 8 can be extended from the first tube body 7, and the locking assembly arranged on the second tube body 8 will also move axially synchronously until the locking assembly moves to the first clamping groove 71 on the inner wall of the first tube body 7. Under the action of the two first springs 66, the two locking blocks 6 in the locking assembly are radially away from each other and unfolded along the first tube body 7, so that the locking bodies 64 on the two locking blocks 6 are locked in the first clamping groove 71, which is the locked state of the locking assembly. It can be known that the second tube body 8 can be stably locked on the first tube body 7 through the locking assembly to form a stable unfolded state of the second tube body 8 and the first tube body 7.

[0050] For example, when the telescopic baton needs to be retracted, the unlocking rod 9 can be specifically driven to approach the locking assembly on the second tube body 8 until the unlocking rod 9 penetrates into the unlocking channel formed between the locking extension sections 65 on the two locking blocks 6, and the two locking blocks 6 are synchronously driven to approach each other and retract along the radial direction of the first tube body 7, so that the locking bodies 64 on the two locking blocks 6 are disengaged from the first slot 71. At this time, the locking assembly can slide axially along the first tube body 7. This is the unlocked state, and the second tube body 8 can be retracted into the first tube body 7.

[0051] It can be seen that the two locking blocks 6 will specifically adopt a symmetrical structure, so the limiting grooves 62 on the two locking blocks 6 will also be aligned, and the limiting protrusions 63 on the two locking blocks 6 will also be aligned. When the unlocking rod 9 is inserted into the semicircular hole 61 of the locking extension section 65 on the two locking blocks 6, the unlocking rod 9 will act on the locking extension section 65 on the two locking blocks 6 at the same time, and can more synchronously control the two locking blocks 6 to move toward each other without any time lag.

[0052] In an optional embodiment, two first slots 71 are provided on the inner wall of the first tube body 7, and in the locked state, one locking block 6 in the locking assembly on the second tube body 8 is locked in one of the first slots 71. With such a configuration, when the telescopic baton needs to be unfolded for use, the second tube body 8 can extend from the first tube body 7, and the locking assembly provided on the second tube body 8 will also move axially synchronously until the locking assembly moves to the first slot 71 on the inner wall of the first tube body 7. Under the action of the two first springs 66, the two locking blocks 6 in the locking assembly are spread apart from each other along the radial direction of the first tube body 7, so that the two locking blocks 6 are locked in the two first slots 71 one by one, and a stable locking structure can be formed respectively.

[0053] In other optional embodiments, the first clamping groove 71 is annular, and in the locked state, the two locking blocks 6 in the locking assembly on the second tube 8 are locked together in the annular first clamping groove 71. Such a configuration can also achieve that the two locking blocks 6 are stably locked in the annular first clamping groove 71, and the structure is simple, which is convenient for manufacturing and production, and reduces the manufacturing difficulty.

[0054] In an optional embodiment, the telescopic baton further includes a third tube body 10 , which is nested inside the second tube body 8 and can be axially telescopic relative to the second tube body 8 , and a second slot 81 is provided on the inner wall of the second tube body 8 .

[0055] The locking components in the telescopic baton may be provided with at least two groups, wherein one group of locking components is provided at one end of the second tube body 8 and at a relative position to the first slot 71, and the other group of locking components is provided at one end of the third tube body 10 and at a relative position to the second slot 81.

[0056] For the locking assembly on the third tube body 10, the locking assembly has a locked state and an unlocked state. In the locked state, the first spring 66 acts on the two locking blocks 6 to spread away from each other radially along the second tube body 8, so that the two locking blocks 6 are locked in the second slot 81; in the unlocked state, the unlocking rod 9 penetrates into the unlocking channel and synchronously drives the two locking blocks 6 to move closer to each other and shrink inward along the radial direction of the second tube body 8, so that the two locking blocks 6 are disengaged from the second slot 81 and can slide axially along the second tube body 8.

[0057] It can be seen that the unlocking rod 9 can unlock the locking assembly on the second tube body 8, and can also unlock the locking assembly on the third tube body 10, and can specifically retract the second tube body 8 into the first tube body 7, and specifically retract the third tube body 10 into the second tube body 8. The second tube body 8 and the third tube body 10 can be unlocked specifically by using an unlocking rod 9. The operation is simple and convenient, and it is easy for users to use.

[0058] In an optional embodiment, two second slots 81 are provided on the inner wall of the second tube body 8, and in the locked state, one locking block 6 in the locking assembly on the third tube body 10 is locked in one of the second slots 81. With such a configuration, when the telescopic baton needs to be deployed for use, the third tube body 10 can extend from the second tube body 8, and the locking assembly provided on the third tube body 10 will also move axially synchronously until the locking assembly moves to the second slot 81 on the inner wall of the second tube body 8. Under the action of the two first springs 66, the two locking blocks 6 in the locking assembly are deployed away from each other along the radial direction of the second tube body 8, so that the two locking blocks 6 are locked in the two second slots 81 one by one, and can each form a stable locking structure.

[0059] In other optional embodiments, the second slot 81 is annular, and in the locked state, the two locking blocks 6 in the locking assembly on the third tube 10 are locked together in the annular second slot 81. Such a configuration can also achieve that the two locking blocks 6 are stably locked in the annular second slot 81, and the structure is simple, easy to manufacture, and reduces the manufacturing difficulty.

[0060] In an optional embodiment, the two locking blocks 6 in the same locking assembly have the same configuration. In this way, only one mold is needed to produce multiple locking blocks 6, which can effectively reduce the manufacturing cost of the telescopic baton and improve economic benefits.

[0061] In an optional embodiment, an unlocking button is provided at the other end of the first tube 7, and the unlocking button can move axially along the first tube 7, and the unlocking rod 9 is fixedly connected to the unlocking button; a second spring is provided between at least one of the unlocking button or the unlocking rod 9 and the inner wall of the first tube 7. In this way, when it is necessary to drive the unlocking rod 9 to move axially along the first tube 7, the user can press the unlocking button, and the unlocking button moves axially along the first tube 7, thereby driving the unlocking rod 9 to move axially along the first tube 7, thereby unlocking the locking assembly on the second tube 8 or unlocking the locking assembly on the third tube 10. In addition, a second spring is also provided to ensure that the unlocking button and the unlocking rod 9 can automatically reset after being released, thereby reducing the difficulty of operation.

[0062] In an optional embodiment, the shape of the side of the limiting protrusion 63 away from the locking extension section 65 in the same group of locking components is arched. Such a configuration can enhance the structural strength of the limiting protrusion 63 to a certain extent and extend its service life.

[0063] In an optional embodiment, the locking body 64, the locking extension 65 and the limiting protrusion 63 in the same group of locking components are integrally formed. Such a configuration can enhance the overall structural strength of the locking block 6 to a certain extent, prolong the service life, and at the same time, the structure is simple, easy to manufacture and reduce the manufacturing difficulty.

[0064] In an optional embodiment, in the same set of locking components, the length of the limiting protrusion 63 is less than or equal to the depth of the limiting groove 62 to avoid interference. Optionally, the length of the limiting protrusion 63 can be 1 cm-2 cm, and the depth of the limiting groove 62 can be 1 cm-2.5 cm.

[0065] In summary, the utility model is a telescopic baton, which may specifically include a first tube body 7, a second tube body 8, a third tube body 10, an unlocking rod 9 and a locking assembly. The second tube body 8 is nested inside the first tube body 7, and an annular first card groove 71 is provided on the inner wall of the first tube body 7. An unlocking button is provided at the end of the first tube body 7, and the button is connected to the unlocking rod 9. The unlocking rod 9 is arranged axially and is equipped with a second spring to ensure that the unlocking button and the unlocking rod 9 can automatically reset after being released. One end of the second tube body 8 is designed with a radially telescopic new butterfly-shaped locking assembly, which can be completely received in the annular first card groove 71, or slide axially along the inner wall of the first tube body 7 when needed.

[0066] The novel butterfly-shaped locking assembly is composed of two arch-shaped locking blocks 6, each of which is provided with a semicircular hole 61, a limiting groove 62 and a limiting protrusion 63. This design can ensure the tightness during locking and the smooth transition during operation. Two spring mounting holes are opened on the opposite sides of the two locking blocks 6, and a first spring 66 is installed in one spring mounting hole, so that the two locking blocks 6 can maintain a dislocated state under the action of the first spring 66, that is, the two locking blocks 6 will move away from each other and lock in the first slot 71, thereby ensuring the stable locking of the first tube 7 and the second tube 8. When the unlocking rod 9 is inserted into the semicircular holes 61 of the two arch-shaped locking blocks 6, the two originally dislocated semicircular holes 61 can be aligned, so that the two locking blocks 6 shrink inward, that is, the two locking blocks 6 are close to each other and disengaged from the first slot 71, and the limiting protrusion 63 enters the limiting groove 62 accordingly, thereby achieving unlocking.

[0067] The telescopic baton may further include a third tube body 10, which is nested inside the second tube body 8, and a novel butterfly-shaped locking assembly is also installed at one end of the third tube body 10. In the locked state, the two novel butterfly-shaped locking blocks 6 are stably locked in the second slot 81 in the second tube body 8 under the action of the first spring 66, preventing the third tube body 10 from retracting.

[0068] When unlocking is required, just press the unlocking button, and the unlocking rod 9 will be inserted into the semicircular holes 61 of the two new butterfly-shaped locking blocks 6, aligning the originally misaligned semicircular holes 61, so that the two locking blocks 6 shrink inward, that is, the two locking blocks 6 approach each other and disengage from the second slot 81, and the limiting protrusion 63 corresponds to enter the limiting slot 62, thereby allowing the third tube body 10 to retract freely, completing the unlocking process.

[0069] Therefore, the telescopic baton has the following beneficial effects for reference:

[0070] (1) The two locking blocks 6 move simultaneously. Due to the symmetrical structure of the two locking blocks 6, when the unlocking rod 9 is inserted into the semicircular holes 61 on the two locking blocks 6 to form an unlocking channel, the unlocking rod 9 acts on the locking extension sections 65 of the two locking blocks 6 at the same time, so that the two locking blocks 6 move toward each other without any time lag.

[0071] (2) The two locking blocks 6 are specifically limited to each other by the limiting groove 62 and the limiting protrusion 63, so that the two locking blocks 6 can only move horizontally in the radial direction without tilting, so as to solve the problem that the drum disc lock plate of the existing design deviates from the groove position, and can effectively compensate for the inward tilting and sliding lock of the disc when it is impacted, and completely solve the structural defects of the mechanical baton locking plate. This design can truly solve the problem that the existing telescopic baton locking disc deviates from the groove, resulting in tilting and sliding lock and unsmooth stick ejection.

[0072] (3) The molding cost is greatly reduced. This is because the two locking blocks 6 are symmetrical and only require one mold for manufacturing. Therefore, the manufacturing cost of the telescopic baton can be effectively reduced.

[0073] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
