Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a portable telescopic two-handed sword. Background Technology

[0002] Recently, with the improvement of people's living standards and the development of sports, swordsmanship has become increasingly popular because it can improve physical fitness and make the body more agile and graceful. Two-handed swords typically consist of a blade, hilt, and possibly a scabbard. Their generally long length makes them extremely inconvenient to carry and store. This inconvenience often leads to deformation of the sword, affecting its functionality. Furthermore, the weight of existing two-handed swords is generally constant, failing to meet the needs of practitioners who wish to increase or decrease the weight of their swords to improve their skill level, strength, and coordination.

[0003] In view of this, it is necessary to design a portable telescopic two-handed sword to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a portable telescopic two-handed sword that allows for the extension and retraction of the sword blade for easy carrying, and also allows for the adjustment of the weight of the two-handed sword as needed, which helps practitioners improve their level of two-handed sword practice and their own strength and coordination.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A portable retractable two-handed sword, comprising:

[0007] The sword blade comprises multiple hollow sword segments that are nested together and interconnected internally, allowing adjacent sword segments to expand and contract. A limiting structure is provided between adjacent sword segments to ensure that the adjacent sword segments are in a relatively stable unfolded state. A cavity structure is also provided on the sword segment at the front end of the sword blade to facilitate the placement of a counterweight.

[0008] The sword hilt, connected to the sword blade, has a cavity structure for facilitating the placement of a counterweight; and

[0009] The elastic element has two ends connected to the hilt and the sword section located at the front end of the sword body, respectively. The hilt is also provided with a control structure that allows the elastic element to switch between a contracted state and an unfolded state. When the elastic element switches from a contracted state to an unfolded state, the sword body is automatically unfolded simultaneously. When the sword body is unfolded, the elastic element also serves as a support element that supports the sword body to a certain extent.

[0010] As a further improvement of this utility model, the limiting structure includes an elastic telescopic clip disposed on the sword section with its telescopic direction perpendicular to the length direction of the sword body, and corresponding grooves disposed on adjacent sword sections.

[0011] As a further improvement of this utility model, the cavity structure includes a cavity disposed within the sword section with an opening at the end away from the hilt, and a sealing element detachably connected to the sword section for sealing the opening of the cavity.

[0012] As a further improvement of this utility model, a cavity for accommodating an elastic element is provided on the sword section at the front end of the sword blade, which is connected to other sword sections, and the cavity is located on the side of the cavity.

[0013] As a further improvement of this utility model, the cavity structure includes a cavity with an opening at the end away from the blade inside the hilt, and a sealing member detachably connected to the hilt body for sealing the cavity opening.

[0014] As a further improvement of this utility model, a miniature speaker is also provided on the sword hilt.

[0015] As a further improvement of this utility model, the sword handle is also provided with several protrusions for anti-slip and massage function.

[0016] As a further improvement of this utility model, the control structure includes a rod that passes through the elastic member and is coaxial with the elastic member, and a locking mechanism for switching the rod between a locked state locked on the hilt and a free state away from the hilt, such that when locked, the elastic member is in a contracted state, and when free, the elastic member is in an expanded state.

[0017] As a further improvement of this utility model, the locking mechanism includes a linkage rod assembly with an opening and closing port formed near one end of the blade, a control component for controlling the switching between the opening and closing port in two states, and a limiting block disposed on the rod body, such that when the opening and closing port is in a locked state, the limiting block engages with the opening and closing port to lock the rod body, and when the opening and closing port is in an open state, the rod body disengages from the opening and closing port.

[0018] As a further improvement of this utility model, when the elastic element is in an unfolded state, the length of the elastic element is greater than the length of the rod.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model sets the sword blade into a multi-segment interlocking structure and sets an elastic element between the sword segment at the front end of the sword blade and the hilt. At the same time, a control structure is set on the hilt to control the elastic element to switch between the extended and retracted states. The two-handed sword blade can be extended and retracted as needed for easy carrying. At the same time, the combination of the elastic element and the control structure can also quickly realize the extension control of the sword blade, making it more convenient to use.

[0021] 2. By setting a limiting structure between adjacent sword sections, this utility model enables the sword to remain relatively stable when it is in an unfolded state under the action of the limiting structure, ensuring that the sword will not shrink unexpectedly when it is in an unfolded state. At the same time, the elastic element can also play a role in supporting the sword to a certain extent when it is in an unfolded state. Thus, under the action of the limiting structure and the elastic element, the sword can always maintain a good stable state when it is in an unfolded state.

[0022] 3. This invention, by incorporating a cavity structure in the front section of the blade, allows for the convenient placement of counterweights within this cavity to adjust the blade's center of gravity and increase its weight. Furthermore, the presence of a cavity structure in the hilt to accommodate the counterweights also allows for increased hilt weight, enabling practitioners to adjust the weight of their two-handed swords as needed. This helps improve their skill level, strength, and coordination. Moreover, compared to uniformly increasing the weight of the entire blade or only in the middle section, this invention allows for weight distribution at both ends, enhancing the practitioner's experience and facilitating better control of the two-handed sword.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0035] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0036] Please see Figures 1-8 As shown, this utility model provides a portable telescopic two-handed sword, comprising:

[0037] The sword body 10 includes multiple hollow sword segments that are nested together and interconnected internally, allowing adjacent sword segments to be extended and retractable. A limiting structure is provided between adjacent sword segments to ensure that the adjacent sword segments are in a relatively stable unfolded state. A cavity structure is also provided on the sword segment at the front end of the sword body 10 to facilitate the placement of counterweights.

[0038] A hilt 60, connected to the blade 10, is provided with a cavity structure for facilitating the placement of a counterweight; and

[0039] The elastic element 30 has two ends connected to the hilt 60 and the sword section located at the front end of the blade 10, respectively. The hilt 60 is also provided with a control structure that allows the elastic element 30 to switch between a contracted state and an extended state. When the elastic element 30 switches from a contracted state to an extended state, the blade 10 is automatically extended simultaneously. When the blade 10 is in the extended state, the elastic element 30 also serves as a support for the blade 10 to a certain extent.

[0040] For example, the blade 10 has a four-section design, such as... Figure 3 As shown, along a direction 60 degrees away from the hilt, the sword sections are, in order, the first sword section 11, the second sword section 12, the third sword section 13, and the fourth sword section 14.

[0041] The limiting structure includes an elastic telescopic latch on the sword section whose telescopic direction is perpendicular to the length direction of the sword body 10, and a corresponding groove 24 on the adjacent sword section. When the sword body 10 is contracted, the elastic telescopic latch is in a contracted state between the adjacent sword sections. When the sword body 10 is extended until the elastic telescopic latch moves to be opposite the groove 24, the elastic telescopic latch is extended by the restoring force to engage with the groove 24.

[0042] When the blade 10 is in the unfolded state, the top of the first blade segment 11 and the bottom of the second blade segment 12, the top of the second blade segment 12 and the bottom of the third blade segment 13, and the top of the third blade segment 13 and the bottom of the fourth blade segment 14 are all fixed by limiting structures. The limiting structures are described below using the first blade segment 11 and the second blade segment 12 as examples.

[0043] like Figure 6As shown, the first sword segment 11 is sleeved around the outer periphery of the second sword segment 12. The bottom of the second sword segment 12 is symmetrically provided with elastic telescopic clips. Each elastic telescopic clip includes a storage groove 21 on the second sword segment 12 and a spherical iron piece 22 connected to the storage groove 21 via a first spring 23. First limiting plates 211 are provided on both sides of the opening of the storage groove 21, and a second limiting plate 221 is correspondingly provided on the side of the spherical iron piece 22 closest to the storage groove 21. This ensures that, under the action of the first limiting plate 211 and the second limiting plate 221, the bottom of the spherical iron piece 22 is always located within the storage groove 21. In other words, the movement path of the spherical iron piece 22 is limited by the cooperation of the first limiting plate 211 and the second limiting plate 221, preventing the spherical iron piece 22 from detaching from the storage groove 21. When the sword body 10 is in a retracted state, the top of the spherical iron plate 22 abuts against the side wall of the first sword section 11, and the first spring 23 is in a retracted state. When the sword body 10 changes from a retracted state to an extended state, the second sword section 12 slides relative to the first sword section 11, causing the elastic telescopic clip to move to be opposite the groove 24. The spherical iron plate 22 is extended by the restoring force of the first spring 23 and engages in the groove 24, so that the first sword section 11 and the second sword section 12 remain relatively fixed. When the sword body 10 is contracted by force, the spherical iron plate 22 is contracted towards the second sword section 12 until the top of the spherical iron plate 22 abuts against the side wall of the first sword section 11. As the sword body 10 continues to contract, the spherical iron plate 22 disengages from the groove 24, so that the second sword section 12 can be retracted into the first sword section 11.

[0044] For example, the storage slot 21 is in the shape of an inverted trapezoid.

[0045] The spherical surface of the spherical iron plate 22 facilitates the locking and fixing between adjacent sword segments and the release of the fixing under the action of external force.

[0046] Specifically, the fourth segment 14 has a chamber 141 in its middle that communicates with other segments to accommodate the elastic element 30. Figure 7 One end of the elastic element 30 is fixed to the end of the chamber 141 away from the third sword section 13, and the other end of the elastic element 30 is fixed to the hilt 60.

[0047] Specifically, the control structure includes a rod 41 that passes through the elastic member 30 and is coaxial with the elastic member 30, and a locking mechanism 42 for switching the rod 41 between a locked state locked on the sword hilt 60 and a free state away from the sword hilt 60, such that when locked, the elastic member 30 is in a contracted state, and when free, the elastic member 30 is in an extended state.

[0048] The locking mechanism 42 includes a linkage rod assembly with an opening and closing port formed near one end of the blade 10, a control component for controlling the switching between the opening and closing port in two states, and a limiting block 411 disposed on the rod body 41. When the opening and closing port is locked, the limiting block 411 engages with the opening and closing port, thus locking the rod body 41. When the opening and closing port is open, the rod body 41 disengages from the opening and closing port, and the rod body 41 is free.

[0049] For example, one end of the rod 41 is fixed to the end of the chamber 141 away from the third sword section 13, and the other end of the rod 41 is free. The limiting block 411 is provided at the free end of the rod 41 and is in the shape of a frustum. The diameter of the frustum gradually increases in the direction away from the sword handle 60, and the maximum diameter of the frustum is smaller than the inner diameter of the elastic element 30.

[0050] For example, such as Figure 1 and Figure 2 As shown, the hilt 60 includes a pommel 61, a handle 62, and a guard 63 connected in sequence.

[0051] The locking mechanism 42 is provided on the sword guard 63, and the sword guard 63 is provided with a receiving cavity 631 for accommodating the locking mechanism 42. The sword guard 63 is provided with a transverse through hole 632 with a diameter greater than the maximum diameter of the limit block 411 and smaller than the diameter of the spring, corresponding to the movement path of the rod 41. The receiving cavity 631 is also provided with a through hole for the rod 41 to extend into the receiving cavity 631.

[0052] like Figure 8 As shown, the linkage assembly includes a first horizontal bar 421, one end of which is rotatably connected to the sword guard 63 and the other end of which is connected to the sword guard 63 via a second spring 424; and a second horizontal bar 422, the middle of which is rotatably connected to the sword guard 63 and the end furthest from the sword guard 63, which is connected to the sword guard 63 via a third spring 425. The end of the second horizontal bar 422 near the sword hilt 62 abuts against the first horizontal bar 421 via a vertical bar 423, and the contact point between the vertical bar 423 and the first horizontal bar 421 is located between the first horizontal bar 421 and the sword guard 63. 3. Rotate the connection point away from the sword handle 62. The first horizontal bar 421 and the second horizontal bar 422 are also provided with protruding blocks 426 at the ends away from the sword handle 62, so that an opening and closing opening is formed at the ends of the first horizontal bar 421 and the second horizontal bar 422 away from the sword handle 62. In the initial state, the distance between the two protruding blocks 426 is less than the maximum diameter of the frustum. A limited area is formed between the two horizontal bars, the vertical bar 423 and the protruding blocks 426, which can lock the bar body 41. At this time, the opening and closing opening is locked.

[0053] The control lever consists of a transmission rod 427 with one end abutting against the vertical rod 423 and a push part 428 with a diameter larger than the diameter of the transmission rod 427 located at the end of the transmission rod 427 away from the vertical rod 423. A mounting hole is provided on the hilt 60 corresponding to the push part 428, so that the push part 428 extends out of the hilt 60 through the mounting hole. Figure 2), so as to facilitate operation;

[0054] The specific operation of the locking mechanism 42 is as follows: When the sword body 10 is in a retracted state, the free end of the rod 41 is confined within the confined area, and the elastic element 30 is in a retracted state. When it is necessary to use the two-handed sword, the pressing part 428 is pressed, and the transmission rod 427 moves downward, causing the vertical rod 423 to move downward, while driving the second horizontal rod 422 to rotate around its rotational connection point with the sword guard 63 and driving the first horizontal rod 421 to rotate around its rotational connection point with the sword guard 63. At this time, the third spring 425 and the second spring 424 are both retracted, and the ends of the two horizontal rods away from the sword handle 62 move away from each other, so that the distance between the two protrusions 426 is greater than the maximum diameter of the truncated cone. The rod 41 is disengaged from the confined area, that is, the opening is in an open state at this time.

[0055] For example, both protrusions 426 are right-angled triangles and are mirror-symmetrical. The following description uses the protrusion 426 on the first crossbar 421 as an example.

[0056] The right-angled side of the protrusion 426 is connected to the first crossbar 421, and the hypotenuse of the protrusion 426 is close to the side of the blade 10 and is inclined upward towards the direction of the second crossbar 422. The specific shapes of the two protrusions 426 and their cooperation with the frustum-shaped limiting block 411 at the free end of the rod 41 can achieve full locking of the rod 41.

[0057] When the blade 10 needs to be retracted, the shaft 41 is moved towards the hilt 60 with the assistance of an external force. For example, the practitioner holds the hilt 60 and presses the front end of the blade 10 against the wall to compress it. At the same time, the practitioner presses the push part 428 to open the opening and closing position, so that the free end of the shaft 41 extends to the limited area. When the push part 428 is released, the opening and closing position returns to the locked position, that is, the shaft 41 is locked in the limited area. At this time, the maximum diameter of the frustum of the free end limiting block 411 of the shaft 41 abuts against the right angle side of the protrusion 426.

[0058] For example, when the elastic element 30 is in an unfolded state, the length of the elastic element 30 is greater than the length of the rod 41; the elastic element 30 is a spring.

[0059] Specifically, the cavity structure includes a cavity 51 located within the fourth sword section 14, opening at the end furthest from the hilt 60. Figure 7 ) and a sealing element 52 for sealing the opening of the cavity 51, which is detachably connected to the fourth segment 14. Figure 1 ).

[0060] For example, there are two cavities 51, which are located on both sides of the chamber 141 respectively, and the seal 52 is threadedly connected to the fourth sword segment 14.

[0061] Specifically, such as Figure 1As shown, the cavity structure includes a cavity 621 located inside the hilt 62 with an opening at one end away from the blade 10. The hilt 62 is detachably connected to the pommel 61, so that the pommel 61 serves as a sealing element to close the opening of the cavity 621. For example, the pommel 61 and the hilt 62 are connected by threads. There are two cavities 621, which are symmetrically arranged around the center of the hilt 62.

[0062] Specifically, the hilt 62 and the guard 63 are also detachably connected; for example, the hilt 62 and the guard 63 are connected by threads.

[0063] For example, the hilt 62 is provided with a number of protrusions 622 for anti-slip and massage function;

[0064] The blade is in an unsharpened state at point 10.

[0065] The pommel 61 is also equipped with a miniature speaker 70 to assist in practice. Regarding the miniature speaker 70, an existing miniature speaker 70 is used and installed on the pommel 61, so that the control terminal and charging terminal of the miniature speaker 70 are both located on the pommel 61 for easy control and charging.

[0066] In the initial state, the two-handed sword is retracted for easy carrying. At this time, the shaft 41 is locked onto the guard 63 under the action of the locking mechanism 42, and the elastic element 30 is retracted. When practice is needed, the push-button 428 is pressed, and the transmission rod 427 moves downward, causing the opening and closing port of the linkage group to open. Under the restoring force of the elastic element 30, the shaft 41 is released from the restricted area, and each sword segment unfolds in sequence with the extension of the spring until the spherical iron plate 22 between the adjacent sword segments engages in the groove 24, so that the sword 10 is in a relatively stable state. At this time, practice can be carried out. If necessary, the sword 10 can be shaken to unfold it, or external force can be used to pull the sword 10 open.

[0067] When it is necessary to increase the weight of the blade 10 or the hilt 60, the corresponding counterweight can be configured in the cavity 51 of the fourth blade section 14 or the cavity 621 of the hilt 60 as needed, so that the portable telescopic two-handed sword can meet the needs of people of different genders and different age groups.

[0068] In addition, the Mini Speaker 70 can be used as an aid during practice.

[0069] For example, the hilt 60 is 40cm long, each section of the sword is 27cm long, and the blade 10 has a maximum thickness of 2-4cm.

[0070] In this example, the elastic element 30 is fixed at a distance of 2cm from one end of the fourth sword section 14 to the end of the fourth sword section 14 away from the third sword section 13. The other end of the elastic element 30 is fixed at the junction of the sword guard 63 and the first sword section 11. When the sword is fully extended, the elastic element is in a free-stretched state, that is, the length of the elastic element 30 in the free-stretched state is 106cm. When the sword 10 is retracted, the amount of retraction of the elastic element 30 is 45%, that is, the overall length of the sword 10 when retracted is 60cm. The overall length of the two-handed sword is reduced from 148cm to 100cm, making it more convenient to carry.

[0071] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
