Description

Technical Field

[0001] The present invention belongs to the technical field of ice skates, and particularly relates to a new type of multi-purpose speed skating blade.

Background Art

[0002] With the development of society and the continuous progress of mankind, various advanced devices have been continuously developed, and the quality of people's lives has been greatly improved. In people's spare time, people are becoming more and more enthusiastic about sports. As a sport, ice skating has developed rapidly in recent years. People are becoming more and more interested in ice skating, and thus people are paying more and more attention to the speed skating blades they use.

[0003] Speed skating blades are divided into dislocated ice blades and positioned ice blades. The dislocated ice blade has a movable heel, a large ice contact point, the movement is easy to stretch, and the generated speed is fast, which is suitable for speed skating on large tracks; the positioned ice blade has a fixed heel, a small ice contact point, the movement is difficult to stretch. Because the short track has a small circle, most straight lines are only two steps and then enter the curve. The short track curve is relatively sharp. The positioned ice blade can fix the foot, step firmly on the curve, and is not easy to fall, which is suitable for short track speed skating. The comparative document with the publication number CN204364851U discloses a multi-purpose speed skating blade that can perform morphological switching. When switching between the dislocated ice blade and the positioned ice blade, bolts are used to fix the blade body and the heel part to form the shape of the positioned ice blade. When it is necessary to switch to the shape of the dislocated ice blade, the bolts need to be removed. Not only is the switching not convenient, but also the long-term switching, disassembly and installation of the bolts are likely to cause the bolts and the threads of the threaded holes to slip, resulting in inoperability. Moreover, when the shape of this speed skating blade is switched, a tension spring is required to pull the displacement frame back to its original position. Therefore, the elastic force decreases after long-term use and often needs to be disassembled and replaced, wasting time and cost. And frequent disassembly will cause the threaded structure to be damaged and unable to be replaced and used again.

Summary of the Invention

[0004] The purpose of the present invention is to provide a new type of multi-purpose speed skating blade that is convenient for switching the use shape of the ice blade and has a return function.

[0005] The present invention is realized by the following technical solutions:

The dislocatable movable frame is provided with a first stop surface at the front end of the hinge axis for restricting the forward flipping of the dislocatable movable frame, and a second stop surface at the rear end of the hinge axis for restricting the backward flipping of the dislocatable movable frame. The dislocatable movable frame is provided with a first magnetic member corresponding to the first stop surface and a second magnetic member corresponding to the second stop surface. The blade body is provided with a third magnetic member and a fourth magnetic member arranged front and back. During the forward flipping of the dislocatable movable frame around the hinge axis, the first magnetic member repels the third magnetic member and the repulsive force gradually increases. During the backward flipping of the dislocatable movable frame around the hinge axis, the second magnetic member attracts the fourth magnetic member and the attractive force gradually increases.

When the dislocatable movable frame flips backward around the hinge axis until the second stop surface fits against the upper surface of the blade body, the shoe body flips with the dislocatable movable frame until the unlocking pin shaft and the unlocking card slot are horizontally opposite. When the unlocking movable member is pushed to move towards the unlocking pin shaft, it drives the unlocking card slot to engage with the unlocking pin shaft to lock the heel of the shoe body and restrict the forward flipping of the dislocatable movable frame around the hinge axis. When the unlocking movable member is pushed to move away from the unlocking pin shaft, it drives the unlocking card slot to disengage from the unlocking pin shaft to release the restriction on the forward flipping of the shoe body and the dislocatable movable frame around the hinge axis.

[0008] For the new multi-purpose speed skating blade as described above, the heel unlocking mechanism further includes a first limiting hole, a second limiting hole, and an elastic snap pin. The first limiting hole and the second limiting hole are arranged on the blade body along the length direction of the blade body. One end of the elastic snap pin is connected to the unlocking movable member, and the other end can extend into the first limiting hole or the second limiting hole. When the unlocking movable member moves to a position where the elastic snap pin corresponds to the first limiting hole and extends into the first limiting hole, the unlocking card slot and the unlocking pin shaft are in a locked state. When the unlocking movable member moves to a position where the elastic snap pin corresponds to the second limiting hole and extends into the second limiting hole, the unlocking card slot and the unlocking pin shaft are in a disengaged state.

[0009] For the new multi-purpose speed skating blade as described above, a shoulder screw is provided on the upper side of the blade body. A sliding groove is arranged in the unlocking movable member along the moving direction of the unlocking movable member. The shoulder screw includes a screw positioning portion and a sliding shoulder arranged at one end of the screw positioning portion. The end of the screw positioning portion away from the sliding shoulder is connected to the blade body.

[0010] As described above for the new multi-purpose speed skating knife, the first magnetic member and the third magnetic member have the same polarity, and the second magnetic member and the fourth magnetic member have opposite polarities. When the dislocated movable frame is flipped forward until the first stop surface fits against the upper surface of the knife body, the first magnetic member and the third magnetic member are opposite and repel each other; when the dislocated movable frame is flipped backward until the second stop surface fits against the upper surface of the knife body, the second magnetic member and the fourth magnetic member are opposite and attract each other.

[0011] As described above for the new multi-purpose speed skating knife, a buffer pad is further provided on the knife body. During the process that the dislocated movable frame is flipped backward around the hinge axis until the second stop surface fits against the upper surface of the knife body, the dislocated movable frame contacts and gradually presses the buffer pad.

[0012] As described above for the new multi-purpose speed skating knife, the knife body includes a knife tube and a blade provided on the lower side of the knife tube. The third magnetic member and the fourth magnetic member are provided inside the knife tube. The knife tube is provided with an installation cavity for installing the third magnetic member and the fourth magnetic member, and a magnetic member fixing block for fixing the third magnetic member and the fourth magnetic member is provided in the installation cavity.

[0013] As described above for the new multi-purpose speed skating knife, a connection locking pin is provided at the bottom of the shoe body. The dislocated movable frame is provided with a first connection hole into which the connection locking pin can be inserted. An automatic locking mechanism is provided between the shoe body and the dislocated movable frame. When the connection locking pin is inserted into the first connection hole, the automatic locking mechanism automatically locks the connection locking pin to restrict the axial movement of the connection locking pin along the first connection hole.

[0014] As described above for the new multi-purpose speed skating knife, the automatic locking mechanism includes a connection locking groove provided on the periphery of the connection locking pin, a locking button movably provided radially along the first connection hole inside the dislocated movable frame, and an elastic element provided between the locking button and the dislocated movable frame. The elastic element is used to make the locking button extend into the connection locking groove to restrict the axial movement of the connection locking pin along the first connection hole.

[0015] As described above for the new multi-purpose speed skating knife, the locking button includes a locking portion and a pressing portion connected to the locking portion. The locking portion extends into the dislocated movable frame and is connected to the elastic element. One end of the pressing portion away from the locking portion extends out of the dislocated movable frame. The elastic element makes the locking portion extend into the connection locking groove and pushes the end of the pressing portion away from the locking portion out of the dislocated movable frame.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention provides a novel multi-purpose speed skating skate, comprising a blade body, a mounting seat arranged on the blade body, a dislocation movable frame hinged on the mounting seat, a shoe body with one end mounted on the dislocation movable frame, and a heel release mechanism arranged between the blade body and the heel of the shoe body for locking the heel of the shoe body, the dislocation movable frame is provided with a first stop surface located at the front end of the hinge shaft for limiting the dislocation movable frame from turning forward, and a second stop surface located at the rear end of the hinge shaft for limiting the dislocation movable frame from turning backward, the dislocation movable frame is provided with a first magnetic member corresponding to the first stop surface, and a second magnetic member corresponding to the second stop surface, and the blade body is provided with a third magnetic member arranged front and back.

[0030] Specific embodiments, such as Figures 1-6The novel multi-purpose speed skating skate shown in the figure comprises a blade body 1, a mounting seat 13 arranged on the blade body 1, a dislocation movable frame 2 hingedly arranged on the mounting seat 13, a shoe body 3 with one end mounted on the dislocation movable frame 2, and a heel release mechanism 4 arranged between the blade body 1 and the heel of the shoe body 3 for locking the heel of the shoe body 3, the dislocation movable frame 2 is provided with a first stop surface 21 located at the front end of the hinge shaft for limiting the dislocation movable frame 2 from turning forward, and a second stop surface 22 located at the rear end of the hinge shaft for limiting the dislocation movable frame 2 from turning backward, the dislocation movable frame 2 is provided with a first stop surface 21 located at the front end of the hinge shaft for limiting the dislocation movable frame 2 from turning backward, and the dislocation movable frame 2 is provided with a second stop surface 22 located at the rear end of the hinge shaft for limiting the dislocation movable frame 2 from turning backward. The movable frame 2 is provided with a first magnetic member 51 corresponding to the first stop surface 21, and a second magnetic member 52 corresponding to the second stop surface 22. The knife body 1 is provided with a third magnetic member 53 and a fourth magnetic member 54 arranged front and back. During the forward flipping of the dislocated movable frame 2 around the hinge axis, the first magnetic member 51 and the third magnetic member 53 repel each other and the repulsive force gradually increases. During the backward flipping of the dislocated movable frame 2 around the hinge axis, the second magnetic member 52 and the fourth magnetic member 54 attract each other and the attractive force gradually increases. When the dislocated movable frame is continuously flipped forward, the repulsive force and attractive force between the magnetic members are used to continuously pull the dislocated movable frame backward to realize the return function of the dislocated movable frame. Compared with the return spring, it does not need to be frequently disassembled and replaced, and has a long service life. The magnetic member is hidden in the knife body and the dislocated movable frame. Compared with the return spring exposed to the outside, the appearance is more beautiful and not easy to be corroded and fail.

[0031] Specifically, the heel unlocking mechanism 4 includes an unlocking movable member 41 movably disposed on the knife body 1 along the length direction of the knife body 1, an unlocking card slot 42 disposed on the unlocking movable member 41, and an unlocking pin shaft 43 disposed on the heel portion of the shoe body 3. When the dislocation movable frame 2 is turned backward around the hinge axis to the second stop surface 22 and fits with the upper surface of the knife body 1, the shoe body 3 is turned with the dislocation movable frame 2 to make the unlocking pin shaft 43 horizontally opposite to the unlocking card slot 42. When the unlocking movable member 41 is pushed to move toward the unlocking pin shaft 43, the unlocking card slot 42 is driven to be engaged with the unlocking pin shaft 43 to lock the heel portion of the shoe body 3 and limit the forward turning of the dislocation movable frame 2 around the hinge axis; when the unlocking movable member 41 is pushed to move away from the unlocking pin shaft 43, the unlocking card slot 42 is driven to disengage from the unlocking pin shaft 43 to release the restriction on the forward turning of the shoe body 3 and the dislocation movable frame 2 around the hinge axis. When the positioning ice skate form needs to be used, the unlocking movable member is pushed to move toward the unlocking pin shaft, driving the unlocking card slot to be engaged with the unlocking pin shaft to lock the heel portion of the shoe body and limit the forward turning of the dislocation movable frame around the hinge axis; when the dislocation ice skate form needs to be used, when the unlocking movable member is pushed to move away from the unlocking pin shaft, the unlocking card slot is driven to disengage from the unlocking pin shaft to release the restriction on the forward turning of the shoe body and the dislocation movable frame around the hinge axis, so that the shoe body and the dislocation movable frame can be turned around the hinge axis, the form switching is more convenient and easy to use, and there is no need to disassemble bolts when switching forms, avoiding the thread slipping of the bolts and the threaded holes due to frequent disassembly of the bolts, resulting in inoperability. At the same time, the repulsive force and attractive force between the magnetic members continuously pull the dislocation movable frame backward, facilitating the switching from the dislocation ice skate form to the positioning ice skate form.

[0032] More specifically, the heel unlocking mechanism 4 further includes a first limiting hole 44, a second limiting hole 45, and an elastic latch 46. The first limiting hole 44 and the second limiting hole 45 are arranged along the length direction of the tool body 1 and opened on the tool body 1. One end of the elastic latch 46 is connected to the unlocking movable member 41, and the other end can extend into the first limiting hole 44 or the second limiting hole 45. When the unlocking movable member 41 moves to a position where the elastic latch 46 corresponds to the first limiting hole 44 and extends into the first limiting hole 44, the unlocking slot 42 and the unlocking pin 43 are in a clamped state; when the unlocking movable member 41 moves to a position where the elastic latch 46 corresponds to the second limiting hole 45 and extends into the second limiting hole 45, the unlocking slot 42 and the unlocking pin 43 are in a disengaged state. By the cooperation of the first limiting hole 44 and the second limiting hole 45 with the elastic latch 46 respectively, the movement of the unlocking movable member 41 along the length direction of the tool body 1 in the natural state is restricted. When it is necessary to unlock the shoe body 3, a person applies a force to the unlocking movable member 41, so that the elastic latch 46 is engaged with the first limiting hole 44 or the second limiting hole 45, and then the unlocking of the shoe body is realized. The operation is more simple and controllable, and it is avoided that the unlocking movable member 41 automatically moves and the unlocking slot 42 and the unlocking pin 43 are disengaged. More specifically, the distance between the central axis of the first limiting hole 44 and the central axis of the second limiting hole 45 is 7 mm.

[0033] Further, a shoulder screw 6 is provided on the upper side of the tool body 1. A sliding groove 411 is provided in the unlocking movable member 41 along the moving direction of the unlocking movable member 41. The shoulder screw 6 includes a screw positioning portion 61 and a sliding shoulder 62 provided at one end of the screw positioning portion 61. One end of the screw positioning portion 61 away from the sliding shoulder 62 is connected to the tool body 1, and the sliding shoulder 62 is located in the sliding groove 411 and can slide relative to the unlocking movable member 41 along the length direction of the sliding groove 411. Specifically, there are two shoulder screws 6, and the two shoulder screws 6 are arranged along the length direction of the tool body 1, so that the sliding of the unlocking movable member 41 is more stable.

[0034] More specifically, the first magnetic member 51 and the third magnetic member 53 have the same polarity, and the second magnetic member 52 and the fourth magnetic member 54 have opposite polarities. When the dislocation movable frame 2 is flipped forward to the first stop surface 21 to be in contact with the upper surface of the tool body 1, the first magnetic member 51 and the third magnetic member 53 are opposite and repel each other; when the dislocation movable frame 2 is flipped backward to the second stop surface 22 to be in contact with the upper surface of the tool body 1, the second magnetic member 52 and the fourth magnetic member 54 are opposite and attract each other. Specifically, the first magnetic member 51, the second magnetic member 52, the third magnetic member 53, and the fourth magnetic member 54 adopt a Halbach magnet array, which can not only generate the strongest magnetic field with the least amount of magnets, but also has a longer service life with this permanent magnet structure.

[0035] Further, a buffer pad 7 is also provided on the tool body 1. During the process that the dislocation movable frame 2 rotates backward around the hinge axis until the second stop surface 22 fits against the upper surface of the tool body 1, the dislocation movable frame 2 contacts and gradually presses the buffer pad 7. Specifically, the buffer pad 7 is a rubber buffer pad, which plays a buffering role to prevent the second stop surface 22 from colliding with the upper surface of the tool body 1 and being damaged.

[0036] Still further, the tool body 1 includes a tool tube 11 and a blade 12 provided on the lower side of the tool tube 11. The third magnetic member 53 and the fourth magnetic member 54 are arranged inside the tool tube 11. An installation cavity 111 for installing the third magnetic member 53 and the fourth magnetic member 54 is provided on the tool tube 11, and a magnetic member fixing block 112 for fixing the third magnetic member 53 and the fourth magnetic member 54 is arranged inside the installation cavity 111. Specifically, the magnetic member fixing blocks 112 are respectively arranged at the front end of the third magnetic member 53 and the rear end of the fourth magnetic member 54, and the magnetic member fixing blocks 112 and the tool tube 11 are connected by bolts to limit the third magnetic member 53 and the fourth magnetic member 54 from moving along the length direction of the tool tube 11.

[0037] Further, a magnetic member installation groove 211 for embedding the first magnetic member 51 is provided on the first stop surface 21, and an installation cover body 212 detachably installed on the magnetic member installation groove 211. This facilitates the disassembly and replacement of the first magnetic member 51. In addition, a magnetic member installation groove for embedding the second magnetic member 52 and an installation cover body detachably installed on the magnetic member installation groove are also provided on the second stop surface 22.

[0038] Still further, the installation cover body 212 is made of aluminum. Specifically, the end surface of the installation cover body 212 away from the magnetic member installation groove 211 is in the same plane as the first stop surface 21. And the end surface of the installation cover body 212 away from the magnetic member installation groove 211 is a smooth plane. This ensures the magnetic force of the magnetic member and improves the utilization rate of the magnetic member.

[0039] Specifically, a connection pin 9 is provided at the bottom of the shoe body 3, a first connection hole 23 for the connection pin 9 to insert is provided on the dislocation movable frame 2, and an automatic locking mechanism 8 is provided between the shoe body 3 and the dislocation movable frame 2. When the connection pin 9 is inserted into the first connection hole 23, the automatic locking mechanism 8 automatically locks the connection pin 9 to limit the connection pin 9 from moving axially along the first connection hole 23. During assembly, the connection pin can be directly aligned and inserted into the first connection hole to realize the connection between the shoe body and the dislocation movable frame, without using bolts, and the loading and unloading are convenient and simple.

[0040] Specifically, the automatic locking mechanism 8 includes a connection card slot 81 provided on the peripheral side of the connection pin 9, a locking button 82 movably arranged radially along the first connection hole 23 within the disengagement movable frame 2, and an elastic element 83 provided between the locking button 82 and the disengagement movable frame 2. The elastic element 83 is used to make the locking button 82 extend into the connection card slot 81 to restrict the axial movement of the connection pin 9 along the first connection hole 23.

[0041] More specifically, the locking button 82 includes a locking portion 821 and a pressing portion 822 connected to the locking portion 821. The locking portion 821 extends into the disengagement movable frame 2 and is connected to the elastic element 83. One end of the pressing portion 822 away from the locking portion 821 extends out of the disengagement movable frame 2. The elastic element 83 makes the locking portion 821 extend into the connection card slot 81 and pushes the end of the pressing portion 822 away from the locking portion 821 out of the disengagement movable frame 2. When the shoe body 3 needs to be disassembled, the pressing portion 822 is pressed to move the locking portion 821 away from the connection card slot 81 until it disengages from the connection card slot 81, and the elastic element 83 is compressed, enabling the connection pin 9 to be axially withdrawn from the first connection hole 23 along the first connection hole 23; when assembling the shoe body 3, after the connection pin 9 is inserted into the first connection hole 23, the elastic element 83 resets and pushes the locking portion 821 into the connection card slot 81 to lock the connection pin 9.

[0042] Further, a first conical surface 91 is provided on the outer peripheral wall of the end of the connection pin 9 away from the shoe body 3. The locking portion 821 includes a second connection hole 8211, and a second conical surface 8212 is provided on the inner peripheral wall of the second connection hole 8211. During the process of inserting the connection pin 9 into the first connection hole 23, the first conical surface 91 and the second conical surface 8212 are in inclined wedge fit to push the locking portion 821 to compress the elastic element 83. When the connection pin 9 is inserted into the first connection hole 23 until the first conical surface 91 disengages from the second conical surface 8212, the elastic element 83 resets and pushes the locking portion 821, so that the inner wall of the second connection hole 8211 extends into the connection card slot 81.

[0043] More specifically, the locking portion 821 movably extends into the disengagement movable frame 2 along the width direction of the disengagement movable frame 2, such that the pressing portion 822 extends out from the side of the disengagement movable frame 2, facilitating the pressing operation.

[0044] Further, a positioning and mounting pin 101 is provided at the bottom of the shoe body 3 along the width direction of the shoe body 3. A positioning and mounting groove 102 penetrating both sides of the disengagement movable frame 2 is provided on the upper surface of the disengagement movable frame 2. When the positioning and mounting pin 101 enters the positioning and mounting groove 102, the connection pin 9 corresponds to the first connection hole 23, enabling automatic positioning and facilitating assembly. More specifically, the bottom of the positioning and mounting groove 102 is inclined towards the front end direction of the shoe body 3 to make the assembly more convenient.
