Summary of the Invention

[0004] The present invention overcomes the disadvantage in the prior art that when a crutch is provided with an umbrella function, the umbrella structure is easily damaged when the crutch is normally used due to the unreasonable arrangement of the umbrella. The present invention provides a multifunctional mountaineering crutch. When the crutch is actually used, the umbrella component is arranged inside the crutch in an assembled manner to prevent the umbrella component from being damaged when the crutch is used. When the umbrella function is needed, the umbrella component can be taken out from the inside of the crutch and the umbrella component and the crutch are combined to form an umbrella.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a multifunctional mountaineering crutch, comprising:

[0006] The crutch body comprises a crutch head and a support rod, wherein the support rod is provided with a hollow cavity;

[0007] The umbrella assembly is arranged in the hollow cavity; the umbrella assembly comprises an umbrella cloth and a plurality of umbrella support rods.

[0008] The present invention arranges the umbrella assembly in the crutch body, and the support rod can well protect the umbrella assembly. When the umbrella is needed, the umbrella assembly is taken out from the hollow cavity of the support rod, and the umbrella assembly and the crutch body are combined to form an umbrella. The umbrella assembly only includes an umbrella cloth and an umbrella support rod, which greatly simplifies the structure of the umbrella assembly and greatly reduces the overall weight, making the weight of the present invention lighter and more portable and easy to carry during normal use. Since the umbrella assembly is arranged in the support rod, the umbrella assembly will not be damaged due to mountain climbing or daily use.

[0009] Preferably, a mounting hole matching the umbrella support rod is provided in the circumferential direction of the crutch head, and a connecting piece is provided at the end of the umbrella cloth to connect with the umbrella support rod.

[0010] A mounting hole connected to the umbrella bracket is provided on the crutch head, so that the umbrella bracket can be directly connected to the crutch head, simplifying the structure of the umbrella assembly; at the same time, a connecting piece is provided at the end of the umbrella cloth to be connected to the umbrella support rod, making it convenient to assemble the umbrella assembly.

[0011] Preferably, the connecting member includes a latch connected to the umbrella cloth, and the umbrella support rod is provided with a latch hole that cooperates with the latch.

[0012] The latch is matched with the latch hole at the end of the umbrella support rod, so that the installation of the umbrella assembly can be more convenient.

[0013] Preferably, the latch is a magnetic latch.

[0014] The magnetic latch allows the latch to be connected to the latch hole through magnetic force when it is engaged, making it faster and more convenient to assemble the umbrella.

[0015] Preferably, a limiting protrusion is provided at the end of the crutch head, an umbrella cloth hole is provided in the middle of the umbrella cloth to cooperate with the limiting protrusion, and a reinforcement ring is provided in the circumferential direction of the umbrella cloth hole.

[0016] In order to enhance the strength of the umbrella assembled with the umbrella assembly and the crutch body, an umbrella cloth hole that cooperates with the limiting protrusion is provided on the umbrella cloth, and a reinforcing ring is provided in the circumferential direction of the umbrella cloth hole to protect the umbrella cloth.

[0017] Preferably, a limiting ring cooperating with the limiting boss is provided on the limiting boss.

[0018] The limiting ring can cooperate with the limiting boss, so that the reinforcement ring can strengthen the umbrella cloth hole.

[0019] Preferably, the umbrella cloth holes are eccentrically arranged on the umbrella cloth.

[0020] In actual use, it is found that since the support rod is placed in front of the hand during use, the area of ​​the umbrella cloth at the rear is smaller than that at the front, making it easier for the rear to be wetted by rain. Therefore, the eccentric setting of the rubber of the present invention makes the area distribution of the umbrella cloth in the circumferential direction of the umbrella cloth hole uneven, which makes it possible to provide good rain protection effect even at the rear of the body during use.

[0021] Preferably, a connecting shaft is provided on the crutch head, and a plurality of rotating rings are sleeved on the connecting shaft along its axial direction, and a reset torsion spring is connected between the rotating ring and the connecting shaft; a fixing hole is provided on the rotating ring to match the umbrella support rod.

[0022] In order to prevent the umbrella support rod from bending due to strong wind during use, a rotating ring is arranged on the connecting shaft, and a fixing hole matching the umbrella support rod is provided on the rotating ring. When the wind is too strong, the umbrella support rod can be blown by the action of the wind, so that the rotating ring can rotate, and the umbrella support rod can be rotated in the direction of the wind, so as to reduce the wind resistance exerted on the umbrella support rod and prevent the umbrella support rod from being broken by the wind; when the wind decreases or stops, the rotating ring can automatically rotate to its original position due to the action of the reset torsion spring, so that the umbrella support rod is reset.

[0023] Preferably, an annular groove is provided on the end surface of the rotating ring, and a ball is provided in the annular groove.

[0024] Ball bearings are arranged on the end faces so as to reduce the friction between adjacent rotating rings and make the rotating rings more sensitive when rotating.

[0025] Preferably, a clamping device is provided on the inner wall of the rotating ring, and the clamping device includes a clamping hole provided on the inner wall of the transmission ring, a clamping pin and a clamping spring are provided in the clamping hole, one end of the clamping pin is provided as a round head, and the other end of the clamping pin is in contact with the clamping spring, and a round head groove matching the round head is provided on the connecting shaft.

[0026] A clamping device is provided so that the support rod will not rotate when subjected to a small wind force. Only when the wind force reaches a certain level, the round head on the rotating ring will disengage from the round head groove, and the rotating ring will rotate, causing the direction of the umbrella support rod to change.

[0027] Compared with the prior art, the present invention has the following advantages: (1) the umbrella assembly is arranged inside the support rod, so that the umbrella assembly can be protected from damage during daily use; (2) the assembly and disassembly are very convenient, and when parts are damaged, they can be replaced, saving resources; (3) the structure is simple, the mass is small, the weight is light, and it is easy to carry; (4) it has a windproof function, which prevents the danger of the umbrella support rod being broken due to excessive wind.

DETAILED DESCRIPTION

[0037] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0038] Example 1: Reference Figures 1 to 4 A multifunctional mountaineering crutch comprising:

[0039] The crutch body is mainly composed of three parts, namely the crutch handle 3, the crutch head 1 and the support rod 2. The interior of the support rod 2 is provided with a hollow cavity; the crutch handle 3 and the crutch head 1 are respectively provided at both ends of the support rod 2, and the crutch handle 3 and the crutch head 1 are threadedly connected to the support rod 2; a cross screwdriver 31 is provided at the end of the crutch handle 3 near the support rod 2, and a flat screwdriver 13 is provided at the end of the crutch head 1 near the support rod 2;

[0040] The umbrella assembly is arranged in the hollow cavity of the support rod 2; the umbrella assembly consists of two parts, an umbrella cloth 4 and a plurality of umbrella rods 5; in this embodiment, the umbrella cloth 4 is a rectangular umbrella cloth, and the umbrella rods 5 are four;

[0041] The crutch head 1 is provided with mounting holes 11 in the circumferential direction thereof, which cooperate with the umbrella support rod 5. Connectors are provided at the four corners of the umbrella cloth 4 to connect with the umbrella support rod 5. The connectors include a latch 44 connected to the umbrella cloth 4. The end of the umbrella support rod 5 is provided with a latch hole 51 that cooperates with the latch 44. The latch 44 is a magnetic latch. During installation, one end of the umbrella support rod 5 is threadedly connected to the mounting hole 11, and the other end of the umbrella support rod 5 cooperates with the latch hole 51 at the end of the umbrella support rod 5 via the latch 44. It should be noted that in order to improve the connection strength between the umbrella support rod 5 and the mounting holes 11, the mounting holes 11 are provided on four different end faces of the crutch head 1, so that the depth of the mounting holes 11 is deeper, thereby improving the connection strength between the umbrella support rod 5 and the mounting holes 11.

[0042] To further enhance the stability and strength of the assembled umbrella, a limiting stud 12 is provided at the end of the crutch head 1. A cloth hole 41 is provided in the center of the umbrella cloth 4, which engages with the limiting stud 12. A reinforcement ring 42 is provided circumferentially around the cloth hole 41. A limiting ring 43 is provided on the limiting stud 12 and is threadedly connected to the limiting stud 12. During installation, the limiting ring 43 constrains the reinforcement ring 42 between the limiting ring 43 and the end of the crutch head 1.

[0043] The working principle of this embodiment is as follows: in normal use, it is a crutch that can meet normal daily use. A conical protrusion 121 is provided at the end of the limiting boss 12 away from the crutch head 1, which can be used for breaking windows or maintaining stability with the muddy ground during climbing; when encountering rain during climbing or outdoor use, the crutch head 1 and the support rod 2 are rotated and separated, the umbrella assembly is taken out, and the crutch head 1 and the support rod 2 are rotated and combined, and then one end of the umbrella support rod 5 is threadedly connected to the mounting hole 11 to connect the umbrella support rod 5 to the crutch head 1, and then the reinforcement ring 43 is sleeved on the limiting boss 12, and the limiting ring 43 is threadedly connected to the limiting boss 12, so that the reinforcement ring 42 is restricted between the limiting ring 43 and the end of the crutch head 1; the other end of the umbrella support rod 5 is matched with the pin hole 51 at the end of the umbrella support rod 5 through the pin 44; after the umbrella assembly is installed, it can be used normally as an umbrella. When the umbrella function is not needed, the umbrella can be removed by performing the above reverse steps. Of course, in addition to keeping out rain, the present invention can also be used as a sunshade, so the use scenario is not specifically limited.

[0044] Example 2: This example is similar in structure to Example 1, except that the umbrella cloth hole 41 is eccentrically arranged on the umbrella cloth 4. In this example, the umbrella cloth hole 41 is arranged at one-third of the center line of the umbrella cloth 4 in the longitudinal direction.

[0045] At the same time, in order to meet the needs of nighttime use, a reserved hole is provided on the crutch handle 3, a flashlight 32 is provided in the reserved hole, and a transparent cover 33 is provided on the reserved hole to match it.

[0046] The working principle of this embodiment is as follows: In actual use, it is found that since the support rod 3 is placed in front of the body during use, the area of ​​the umbrella cloth 4 at the rear is smaller than the area of ​​the umbrella cloth 4 at the front, making it easier for the rear to be wetted by rain. Therefore, the eccentric arrangement of the present invention makes the area distribution of the umbrella cloth 4 in the circumferential direction of the umbrella cloth hole 41 uneven, which makes it possible to achieve a good rain protection effect even at the rear of the body during use.

[0047] At the same time, the flashlight 32 can be provided for outdoor use at night, making it safer to walk at night.

[0048] Example 3: Reference Figures 5 to 8As shown, this embodiment has the same structure as embodiment 1 or embodiment 2, except that a connecting shaft 14 is provided on the crutch head 1, and the connecting shaft 14 is provided with a plurality of rotating rings 6 along its axial direction, and the number of the rotating rings 6 is the same as the number of the umbrella support rods 5; a return torsion spring 61 is connected between the rotating ring 6 and the connecting shaft 14, one end of the return torsion spring 61 is connected to the connecting shaft 14, and the other end of the return torsion spring 61 is connected to the inner wall of the rotating ring 6; a fixing hole 64 is provided on the rotating ring 6 to match the umbrella support rod 5, and only one umbrella support rod 5 is connected to each rotating ring 6; in this embodiment, four rotating rings 6 are provided to match the number of umbrella support rods 5.

[0049] The end surface of the rotating ring 6 is provided with an annular groove 62, in which a ball bearing 621 is disposed. It should be noted that the number of annular grooves 62 can be set to multiple concentric annular grooves 62, which can reduce the friction between adjacent rotating rings 6 and make the rotating ring 6 more sensitive when rotating. At the same time, in order to reduce the mass of the rotating ring 6, a hollow design is adopted except for the necessary structures to reduce the overall mass.

[0050] A clamping device 63 is provided on the inner wall of the rotating ring 6. This clamping device 63 includes a clamping hole 631 provided on the inner wall of the transmission ring 6. A clamping pin 632 and a clamping spring 633 are disposed within the clamping hole 631. The end of the clamping pin 632, which is located near the connecting shaft 14, is provided with a rounded head. The other end of the clamping pin 632 abuts the clamping spring 633. A rounded head groove 131 is provided on the connecting shaft 13 to mate with the rounded head. In this embodiment, two clamping devices 63 are provided, arranged symmetrically about the center of the circular shape of the rotating ring 6.

[0051] The working principle of this embodiment is as follows: during mountain climbing, the wind force on the mountain is unstable. In order to prevent the umbrella support rod 5 from bending due to excessive wind during use, the rotating ring 6 is set on the connecting shaft 14, and a fixing hole 64 matching the umbrella support rod 5 is set on the rotating ring 4, so that when the wind force is too strong, the umbrella support rod 5 can be blown by the action of the wind, so that the rotating ring 4 can rotate, so that the umbrella support rod 5 can be rotated in the direction of the wind, so as to reduce the wind resistance suffered by the umbrella support rod 5 and prevent the umbrella support rod 5 from being broken by the wind; when the wind force decreases or stops, the rotating ring 6 can automatically rotate to its original position through the action of the reset torsion spring 61, so that the umbrella support rod 5 is reset.

[0052] The clamping device 63 is provided so that when the support rod 5 is subjected to a small wind force, the rotating ring 6 will not rotate. Only when the wind force reaches a certain level, the clamping pin 632 on the rotating ring 6 overcomes the force of the clamping spring 633, causing the round head to disengage from the round head groove 141, and then the rotating ring 6 will rotate, causing the direction of the umbrella support rod 5 to change, thereby achieving a windproof effect.

[0053] It should be noted that in order to make the umbrella support rod 5 more windproof in this embodiment, the umbrella cloth 4 is arranged to be pleated, and the outer edge of the umbrella cloth 4 is a rubber rope, so that when the umbrella support rod 5 rotates, the umbrella cloth and the rubber rope can be stretched to ensure that the umbrella support rod 5 can rotate after being subjected to wind force.

[0054] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
