In outdoor activities such as snow climbing or skiing, you may occasionally encounter dangerous situations such as avalanches, stepping into the air, and collapses. After the user is buried by the snow, if the rescue cannot be obtained in time, the life safety of the user will be caused.

The embodiment provides a snow rescue device, which can mark the user's location to the outside world when the user is buried in snow, that is, mark the user's location above the snow surface, so that the rescuers can find the user in time, so that the user can be rescued in time .

As shown in FIGS. 1 to 5 , the snow rescue device includes a device case 10 , a telescoping mechanism 20 and an identification mechanism 30 .

Wherein, the telescopic mechanism 20 includes a plurality of elastic telescopic units 21 , and the plurality of elastic telescopic units 21 are connected sequentially. In an embodiment, the elastic stretch unit 21 may include a contracted state 21a and an extended state 21b, and the elastic stretch unit 21 can switch between the contracted state 21a and the extended state 21b. When the elastic stretch unit 21 is in the contracted state 21a, the elastic potential energy can be stored in the elastic stretch unit 21, and the elastic potential energy can be used to drive the elastic stretch unit 21 to switch from the contracted state 21a to the stretched state 21b. It can be understood that the length of the elastic stretch unit 21 in the stretched state 21b is greater than the length of the elastic stretch unit 21 in the contracted state 21a.

The telescoping mechanism 20 can be telescopically installed in the device case 10 , and the identification mechanism 30 can be installed at one end of the telescoping mechanism 20 .

It can be understood that the snow rescue device may include an in-use state and a non-use state. When the snow rescue device is not in use, each elastic telescopic unit 21 can be in a retracted state 21 a to shorten the length of the telescopic mechanism 20 , and the telescopic mechanism 20 can be retracted in the device casing 10 . At the same time, the identification mechanism 30 can also be shrunk into the device case 10 .

When the snow rescue device is in use, at least one elastic telescopic unit 21 in the telescopic mechanism 20 can be in an extended state 21b to increase the length of the telescopic mechanism 20 . Correspondingly, the retractable mechanism 20 can drive the identification mechanism 30 to extend relative to the device case 10 .

When the user is buried under the snow, the length of the telescopic mechanism 20 can be extended to drive the identification mechanism 30 to protrude above the snow surface, so that rescuers can know the user's position. In addition, when the user is buried under the snow, the user basically has no room for movement. In this application, the elastic potential energy stored in the elastic elastic unit 21 can drive the elastic elastic unit 21 to switch from the contracted state 21a to the extended state 21b to drive the identification mechanism. The 30 protrudes above the snow surface, which can reduce the trouble of manual operation and reduce the user's activities. Correspondingly, it can also avoid the occurrence of dangers such as further snow bank landslides caused by user activities. At the same time, it can also reduce the user's energy consumption. Allows the user to conserve energy.

As shown in FIGS. 1 to 4 , in some embodiments, the axis L of the telescoping mechanism 20 may extend along the height direction of the snow rescue device. A through hole is provided on the side wall of the device housing 10 opposite to the marking mechanism 30 , allowing the marking mechanism 30 and the retractable mechanism 20 to extend out of the device housing 10 . In some embodiments, the side where the through hole is opened in the device case 10 may be the top of the device case 10 , that is, the top of the snow rescue device. Correspondingly, the side wall of the device case 10 opposite to the through hole may be the bottom of the device case 10, that is, the bottom of the snow rescue device.

In some embodiments, the snow rescue device further includes a cover plate 11 for closing the through hole. When the snow rescue device is not in use, the cover plate 11 can cover the position of the through hole. It can be understood that the cover plate 11 is detachably connected to the device case 10 so as to open the through hole. Exemplarily, the cover plate 11 can be fixed at the position of the through hole through the frictional force between the side wall of the cover plate 11 and the inner wall of the through hole.

When the snow rescue device is in use, the cover plate 11 can be separated from the device housing 10 under the push of the identification mechanism 30 to open the through hole, so that the identification mechanism 30 and the telescopic mechanism 20 can extend out of the device housing 10 . During this process, the user does not need to manually open the cover plate 11 , which can reduce the manual operation steps of the user and facilitate the use of the user. It can be understood that the frictional force between the cover plate 11 and the inner wall of the through hole is smaller than the thrust generated when the telescoping mechanism 20 is triggered, so as to make the cover plate 11 leave the position of the through hole smoothly.

Certainly, in some other embodiments, the cover plate 11 can also be arranged at the position of the through hole through screw connection, buckle connection, etc., so that the user can open the through hole.

As shown in FIGS. 4 and 5 , the telescoping mechanism 20 also includes a base 22 . The base 22 can be fixedly connected to an elastic telescopic unit 21 of the telescopic mechanism 20 farthest from the marking mechanism 30 , and the base 22 is connected to an end of the elastic telescopic unit 21 away from the marking mechanism 30 .

As shown in FIG. 3 , in some embodiments, the base 22 can be fixedly connected to the bottom of the device case 10 . Exemplarily, the base 22 can be fixed to the bottom of the device case 10 by means of screw connection, clamping, bonding, etc. Meanwhile, the end of the base 22 away from the elastic telescopic unit 21 is exposed outside the device case 10 .

Furthermore, as shown in FIG. 6 , the base 22 is further provided with a plurality of feet 221 on the side away from the elastic telescopic unit 21 . During use, the feet 221 can be inserted in snow to provide support and fixation. In an embodiment, one end of the leg 221 can be hinged to the base 22 via a rotating shaft (not shown). When the legs 221 are folded, the legs 221 can be embedded in the base 22 , and correspondingly, the base 22 can be provided with an embedding groove 222 for accommodating the legs 221 . In an embodiment, the number of supporting feet 221 can be set to three, four, five, etc.

As shown in FIG. 4 and FIG. 5 , the elastic telescopic unit 21 may include a connecting seat 211 and an elastic member 212 . Wherein, the connecting seat 211 can be used to realize the connection between two adjacent elastic stretching units 21 . Specifically, one end of the connection seat 211 can be connected to one end of the elastic member 212, and the other end of the connection seat 211 can be connected to the elastic member 212 in the adjacent elastic telescopic unit 21, wherein the adjacent elastic telescopic unit 21 can refer to close connection The elastic telescopic unit 21 at one end of the seat 211. In the elastic telescopic unit 21 disposed close to the base 22 , the end of the connection base 211 away from the elastic member 212 can be fixedly connected to the base 22 .

Referring again to FIG. 7 and FIG. 8 , in some embodiments, the elastic member 212 can be a helical shrapnel. The elastic member 212 can include a first end 212a and a second end 212b. When the elastic telescopic unit 21 is in the contracted state 21a, the part between the first end 212a and the second end 212b can be spirally nested in the first end 212a, presenting It is a multi-layer nested spiral structure. In some embodiments, the elastic member 212 can be made by curling a steel sheet. Correspondingly, when the elastic telescopic unit 21 is in the contracted state 21a, the elastic member 212 can store corresponding elastic potential energy.

When the elastic telescopic unit 21 is in the extended state 21b, the second end 212b can pop out relative to the first end 212a, and the elastic member 212 presents a helical tubular structure with a certain length. It can be understood that the length of the elastic member 212 in the stretched state 21b is greater than that in the contracted state 21a.

In some embodiments, the first end 212a of the elastic member 212 can be fixedly connected to the connecting seat 211 of the same unit, and the second end 212b can be fixedly connected to the connecting seat 211 of the adjacent elastic stretching unit 21 .

As shown in Figure 8, in some embodiments, the first end 212a can be fixedly connected with the first connecting pipe 214 by means of welding, clamping, etc. There is an internal thread matched with the first connecting pipe 214, and the detachable connection between the first connecting pipe 214 and the connecting seat 211 can be realized by screwing.

Correspondingly, the second end 212b can be fixedly connected with the second connecting pipe 215 by means of welding, clamping, etc., and the second connecting pipe 215 can also be connected to the connecting seat 211 in the adjacent elastic telescopic unit 21 by screwing. In some embodiments, the second connecting pipe 215 can extend outwards with a certain thickness, or the corresponding end of the corresponding connecting seat 211 has a certain closing inward, so that the second connecting pipe 215 and the corresponding connecting seat 211 can be smoothly connected. Mate connection.

In some other embodiments, the first connecting pipe 214 and the second connecting pipe 215 can also be connected to the corresponding connecting seat 211 by means of welding, clamping, etc. respectively.

In an embodiment, when the second end 212b bounces off relative to the first end 212a, adjacent elastic stretchable units 21 can be pushed to move upwards synchronously.

As shown in FIG. 9 and FIG. 10 , in some embodiments, the elastic stretch unit 21 further includes a locking component 213 for locking the elastic stretch unit 21 in the contracted state 21a.

Specifically, the locking component 213 may include a locking lever 2131 and a connecting wire 2132, and one end of the connecting wire 2132 may be fixedly connected to the second end 212b. The other end of the connecting wire 2132 is fixedly connected to the locking rod 2131 . When the elastic telescopic unit 21 is in the contracted state 21a, the connecting wire 2132 can be passed through the elastic member 212, the locking rod 2131 can be limited to the end of the elastic member 212 close to the connecting seat 211, and the locking rod 2131 is in contact with the connecting seat 211. connect. At the same time, the connecting wire 2132 can pull the second end 212b toward the direction close to the first end 212a, so that the elastic member 212 stores elastic potential energy, so that the elastic member 212 is in a compressed state. During this period, the connecting wire 2132 is under tension. Therefore, through the restraining effect of the locking rod 2131 and the connecting wire 2132, the elastic telescopic unit 21 can be kept in the contracted state 21a.

As shown in FIG. 9 and FIG. 10 , the locking rod 2131 is detachably connected to the connecting seat 211 . When the elastic telescopic unit 21 is in the retracted state 21a, the locking rod 2131 is inserted into the connecting seat 211 to realize the locking action. Correspondingly, a pair of locking holes 2111 matched with the locking lever 2131 is formed on the connecting base 211 , the two locking holes 2111 are arranged coaxially, and the connecting line between the two locking holes 2111 is perpendicular to the axis L. It can be understood that the two locking holes 2111 are provided avoiding the threads in the connecting seat 211 .

When the elastic telescopic unit 21 is in the retracted state 21a, the two ends of the locking rod 2131 can be inserted into the two locking holes 2111 in one-to-one correspondence, and under the action of the locking hole 2111, the locking rod 2131 can be realized. The limit in the direction of the axis L.

When the elastic telescopic unit 21 is switched from the contracted state 21a to the extended state 21b, one end of the locking rod 2131 can be pushed from one side of the connection base 211 out of the locking hole 2111 to enter the connection base 211 . The locking rod 2131 is inclined under the elastic pulling effect of the elastic member 212, and gradually moves away from the first end 212a. The other end of the locking rod 2131 can also gradually slide into the connecting seat 211 , so that the locking rod 2131 and the connecting seat 211 are unlocked, so as to completely release the second end 212 b of the elastic member 212 . Subsequently, the elastic member 212 can release the elastic potential energy, so that the second end 212b springs apart relative to the first end 212a, and the elastic telescopic unit 21 switches to the extended state 21b.

In an embodiment, both ends of the locking rod 2131 can be hemispherical. At the same time, when the locking rod 2131 is plugged into the connecting seat 211, the two ends of the locking rod 2131 can be respectively embedded in the locking holes 2111 on the corresponding sides, or protrude slightly relative to the locking holes 2111. The length, for example, the locking rod 2131 may protrude 0.5 mm, 1.0 mm, etc. relative to the locking hole 2111 . Therefore, during the unlocking process, it is ensured that the locking rod 2131 slides smoothly into the connecting seat 211 .

As shown in FIG. 1 and FIG. 2 , in some embodiments, a plurality of trigger keys 72 corresponding to each locking rod 2131 in the telescoping mechanism 20 are also provided on the device case 10 . In an embodiment, a plurality of trigger keys 72 may also be arranged in sequence along the height direction of the snow rescue device. In use, the user can press a certain trigger key 72 to unlock the corresponding locking lever 2131 and the corresponding connection seat 211 , release the second end 212 b of the corresponding elastic member 212 , and make the elastic member 212 bounce off.

As shown in FIG. 11 , a push rod 721 protrudes from a side of the trigger key 72 close to the telescoping mechanism 20 . When the elastic telescopic unit 21 is in the retracted state 21a, the opposite push rod 721 can be coaxial with the locking rod 2131 . And the diameter of the push rod 721 may be smaller than the diameter of the locking hole 2111 . When the user presses the trigger button 72 , the push rod 721 can be pushed to move, and then the push rod 721 pushes the corresponding locking rod 2131 to unlock with the connecting seat 211 .

As shown in FIG. 1 , FIG. 12 and FIG. 13 , in some embodiments, the snow rescue device further includes a safety catch assembly 73 , which prevents the user from triggering the telescoping mechanism 20 by misoperation in the non-use state.

Specifically, the safety lock assembly 73 may include an actuating key 731 and a stop plate 732 that are connected. Wherein, the execution key 731 is slidably installed on the top of the device case 10, and the sliding direction of the execution key 731 is parallel to the length direction of the snow rescue device. The stop plate 732 can be located in the device housing 10 and can move synchronously with the execution key 731 . In an embodiment, the stop plate 732 may be located between the push rod 721 and the telescoping mechanism 20 .

In the embodiment, the stop plate 732 is provided with a plurality of through holes 733 , and the plurality of through holes 733 are provided in one-to-one correspondence with the plurality of push rods 721 . In the non-use state, along the length direction of the snow rescue device, the through hole 733 is misplaced with the corresponding push rod 721, and the end of the push rod 721 away from the trigger key 72 can be opposite to the non-through hole area in the stopper plate 732 to avoid The push rod 721 touches the corresponding locking rod 2131 .

When using the snow rescue device, the execution key 731 can be pushed to move to drive the stop plate 732 to move relative to the trigger key 72, so that the through hole 733 is opposite to the corresponding push rod 721, that is, the through hole 733 and the push rod 721, locking Rod 2131 is coaxial.
