Description

Technical Field

[0001] The present invention relates to the technical field of compasses, and specifically to a portable random-pointer compass and its usage method. Background Art

[0002] Traditional compasses, also known as gyrocompasses, were initially mostly used for feng shui exploration. Especially in the Liqi sect, they were almost indispensable core tools. Each seemingly simple scale actually reflects the profound understanding of the laws of the universe by the ancients. Ultimately, the compass is not just a tool for determining directions; it is more like a carrier carrying the information of heaven and earth, a link between humans and nature.

[0003] For the random-pointer compass, its concept is completely different. By allowing the pointer to rotate randomly and finally stop at a certain scale position, it realizes the determination of environmental parameters or directions. Although it seems random, it is precisely this randomness that gives it a unique reference value in special scenarios. Different from traditional compasses that rely on a fixed magnetic field, this method can still provide effective information in an interfering environment.

[0004] Most existing compasses are of an integral structure, with the chassis fixedly connected to the inner disk. Although this design has a stable structure, it has certain limitations in daily use. On the one hand, the integral structure has a fixed volume during the carrying process and is difficult to store; on the other hand, it is not convenient for local inspection or component replacement after long-term use. In addition, the holding surface of the hand-held compass is often a smooth curved surface, and long-term thumb pressing is likely to cause a local sense of compression. Especially in a humid environment, sweating on the hand will cause the holding to slip.

[0005] Therefore, the present invention proposes a portable random-pointer compass and its usage method to solve the deficiencies of the existing technology. Summary of the Invention

[0006] In view of the deficiencies of the existing technology, the present invention provides a portable random-pointer compass and its usage method, which solves the problems of inconvenient carrying and poor usage comfort of the existing compass structure.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: A portable random-pointer compass, including a chassis and an inner disk, a gripping mechanism is arranged on the outer side of the chassis, a wristband mechanism is arranged at the bottom of the chassis, a Tianchi is arranged in the middle of the top of the inner disk, a tortoise-shell pointer is rotatably connected to the middle of the top through a damping rotating shaft, and the chassis is connected to the inner disk through a disassembly and fastening mechanism; The disassembly and fastening mechanism includes three fixing grooves and three L-shaped blocks. The three fixing grooves are equidistantly opened at the top of the chassis, and the three L-shaped blocks are fixedly connected to the bottom of the Tianchi at equal distances. The L-shaped blocks are in snap-fit with the fixing grooves. An installation groove is opened on the inner side of each fixing groove, and a moving plate is slidably connected inside the installation groove. A spring is fixedly connected between the moving plate and the installation groove. One end of the moving plate away from the spring is fixedly connected with a top-tightening column. A top-tightening groove is opened on one side of the L-shaped block close to the top-tightening column, and the top-tightening column is in snap-fit with the top-tightening groove.

[0008] Preferably, a connecting block is fixedly connected to one end of the L-shaped block away from the top-tightening column, and a rubber block is fixedly connected to the top of the connecting block. A plurality of fastening grooves are opened inside the chassis, and the rubber block is in snap-fit with the fastening grooves.

[0009] Preferably, the gripping mechanism includes a plurality of gripping grooves, and the plurality of gripping grooves are respectively opened on the side of the chassis.

[0010] Preferably, gripping lines are provided on the outside of the gripping grooves.

[0011] Preferably, the wrist ring mechanism includes a rotating block, the rotating block is rotatably connected to the bottom of the chassis, and a wrist ring is fixedly connected to the outside of the rotating block.

[0012] Preferably, the wrist ring mechanism further includes a storage groove, the storage groove is opened at the bottom of the chassis, and the wrist ring is arranged inside the storage groove.

[0013] Preferably, a buckle groove is opened on the inner side wall of the storage groove.

[0014] Preferably, the head and tail of the turtle shell pointer are indicating needles.

[0015] The present invention also provides a method for using a random pointer that is convenient to carry, including the following steps: S1. Equipment assembly: Align the three L-shaped blocks at the bottom of the inner disk with the fixing grooves at the top of the chassis, and press the inner disk downward to make it snap into the fixing grooves; rotate the inner disk away from the fastening grooves, so that the rubber block is driven to snap into the fastening grooves. At the same time, when the L-shaped blocks are snapped into the fixing grooves, the top-tightening column is pushed by the spring to snap into the top-tightening grooves of the L-shaped blocks to complete the locking; S2. Gripping operation: Press the gripping lines outside the gripping grooves with the thumb of one hand, and hold the bottom of the chassis with the other four fingers; or after lifting the wrist ring from the storage groove through the buckle groove, put it on the wrist and keep the compass stable through the rotating block; S3. Pointer start: Rotate the turtle shell pointer, and use the resistance characteristics of the damping rotating shaft to make the turtle shell pointer freely rotate for 5-8 seconds and then naturally stop; observe the inner disk scale area pointed to by the head or tail of the turtle shell pointer; S4. Storage management: When disassembly is required, rotate the inner disk by pressing it towards the fastening groove, causing the top pressing column to retract under external force. When the inner disk cannot be rotated anymore, it can be lifted upward to release the clamping connection between the L-shaped block and the fixing groove, separating the chassis and the inner disk. The disassembled inner disk can be placed on top of the chassis; fold the wristband and press it into the storage groove.

[0016] The present invention provides a portable random pointer compass and its usage method. It has the following beneficial effects: 1. Through the modular design of the disassembly fastening mechanism and the folding and storage function of the wristband mechanism, the present invention realizes the quick disassembly and assembly and compact storage of the compass components, significantly reducing the carrying volume and meeting the portable requirements of outdoor scenarios.

[0017] 2. Through the arc-shaped gripping groove and the micro-protrusion array of the gripping lines of the gripping mechanism, the present invention forms a multi-point pressure dispersion structure, reducing the pressure on the thumb contact surface and realizing anti-slip control and relief of operation fatigue during single-handed holding.

[0018] 3. The damping adjustment of the rotating block and the elastic deformation of the wristband cooperate with each other to adapt to different wrist curvatures, maintaining the stability of the compass horizontal reference during walking or climbing, and at the same time supporting quick folding and storage into the storage groove at the bottom of the chassis, reducing the occupied space.
