Description

Technical Field

[0001] The present invention relates to a barometer structure, and more particularly to a barometer structure for detecting barometric pressure values.

Background Art

[0002] Conventional mechanical pressure gauges (for example, Patent Document 1) have a coupling method between the storage member and the support member of the pressure gauge that is too complex and requires many machining steps. Its assembly method is irreversible and cannot be reassembled after disassembly, making maintenance difficult. Specifically, the support member is a metal member. After attaching the storage member below the support member, the support member is press-formed by a press-forming device to form a frame bent inward at its lower end edge, and includes the storage member, a pad, and a diaphragm fixed inside the bent frame.

[0003] Such an assembly method was of course stable, but it was necessary to assist the assembly with a press-forming device. Such conventional mechanical pressure gauges could not be disassembled for repair or maintenance. Also, it was difficult to restore the support member to its original state after being processed and deformed by a press-forming device. When disassembling, the frame bent inward of the support member was cut or destroyed, and once the frame bent inward was destroyed, the storage member, the pad, and the diaphragm could not be clamped again. Also, such conventional mechanical pressure gauges had too many parts and required a great deal of labor for assembly. Taking the pointer shaft as an example, it included many members such as a support shaft, a cross bar, a pointer, and a rotating member. When assembling, not only were human resources wasted, but it also went without saying that the component costs were wasted.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The main object of the present invention is to insert the shaft rod at one end of the rotating member into the central guide hole of the first engaging member, abut one end of the pointer on the spiral groove of the guide portion, and at the same time, fit the elastic member of the positioning socket member on the vent hole of the positioning block and abut it on the shaft rod of the rotating member. When the external air pressure is introduced through the vent hole of the positioning block of the positioning socket member to support and expand the elastic member to open, the rotating member is pressed to rotate the pointer upward, and a barometer structure capable of detecting the visualized air pressure value is provided.

Means for Solving the Problems

[0007] In order to solve the above problems, according to the first aspect of the present invention, there is provided a barometer structure including a first engaging member, a second engaging member, a rotating member, and a positioning socket member. The first engaging member has a first hole groove, a second hole groove, a central guide hole communicating with the first hole groove and the second hole groove, and a guide portion provided at the upper end of the central guide hole. On both sides of the guide portion, guide grooves of a first spiral step portion and a second spiral step portion facing in opposite directions are provided. The second engaging member is installed at the bottom of the first engaging member and has a first end portion and a second end portion communicating with each other. The rotating member has a shaft rod, and ribs and pointers extending outward in the horizontal axis direction are respectively provided on both sides of the top end of the shaft rod. The positioning socket member includes a positioning block and an elastic member. A vent hole is formed at the center of the positioning block. One end of the elastic member is fitted on the vent hole, and the other end abuts against the bottom of the rotating member, connecting the first engaging member and the second engaging member up and down. The positioning socket member is fitted at the bottom of the second engaging member, the shaft rod at the bottom of the rotating member is inserted into the central guide hole of the first engaging member, and the pointers and ribs provided on both sides of the top end are horizontally abutted against the guide grooves of the two corresponding spiral step portions of the guide portion. An external air pressure source is combined and connected to the vent hole of the positioning block of the positioning socket member, and air pressure is introduced into the elastic member. When the gas is filled, the bent step portion outside the elastic member extends upward, conducting the power of the acting force upward, actuating the elastic member upward, supporting and expanding it, and at the same time pushing up the rotating member, and rotating the pointer upward along the guide groove. When the gas leaks, the wavy bent step portion on the outer peripheral side that can be expanded and contracted is contracted downward and restored to the folded state, conducting the power of the downward acting force, compressing and lowering the volume space of the elastic member, and converting it into a visualized air pressure value for display. A barometer structure is provided, which is characterized in that.

[0013] Refer to FIGS. 1 to 3. As shown in FIGS. 1 to 3, the first engaging member 20 has a fastening portion 21, an assembling portion 22, a central guide hole 23, and a guide portion 24. Inside the periphery of the fastening portion 21, there is a first hole groove 211 with a top surface recessed inward. At the central portion of the first hole groove 211, a guide portion 24 projects upward corresponding to the upper end of the central guide hole 23. On both sides of the guide portion 24, a first arc cut surface 241 and a second arc cut surface 242 with different heights are provided. At both ends of the two arc cut surfaces, a first angle (lower position) 2411, 2421 and a second angle (higher position) 2412, 2422 are respectively provided. On the first arc cut surface 241, a first spiral step portion D1 is formed from the first angle (lower position) 2411 to the first arc cut surface 241 of the second angle (higher position) 2412 in the upward direction from bottom to top. On the second arc cut surface 242, a second spiral step portion D2 is formed from the first angle (lower position) 2421 to the arc cut surface of the second angle (higher position) 2422 in the upward direction from bottom to top. Inside the assembling portion 22, a second hole groove 221 opening downward is recessed, the central guide hole 23 is communicated with the first hole groove 211 and the second hole groove 221, and a rotating member 40 is inserted therein.

[0014] Refer to FIG. 6. As shown in FIG. 6, on the top surface of the first hole groove 211 of the above-described first engaging member 20, a panel 25 on which a pressure value scale 251 is printed is fitted. The display of the pressure values of the scale 251 on the panel 25 is represented by blocks or colors of different colors for the first block 251a, the second block 251b, and the third block 251c installed adjacent to each other. The first block is set as a low pressure value block indicating values from 0 to 30 degrees, the second block is set as a medium pressure value block indicating values from 30 to 60 degrees, and the third block is set as a high pressure value block indicating values from 60 to 90 degrees. In combination with the pointer swing indicator, a visualized pressure value scale plate is formed.

[0015] The above-mentioned first engaging member 20 includes an outer sleeve 70. The outer sleeve 70 is a PVC panel cover made of a light-transmitting material. A first fitting groove 71 and a second fitting groove 72 for fitting the guide portion 24 of the first engaging member 20 are recessed in the inner center. The first arc-cut surface 241 and the second arc-cut surface 242 of the guide portion 24 of the first engaging member 20 are fitted to form a rotation track groove for rotating the pointer 45 and the rib 44 of the rotating member 40. At a position where the outer edge corresponds to the engaging portion 21 of the first engaging member 20, a corresponding engaging portion 73 is provided to fit the engaging portion 21 on the top surface of the first engaging member 20, forming an accommodation space A and using it as a rotation space for swinging the pointer.

[0016] The above-mentioned first engaging member 20 includes a spring 60. The spring 60 is installed on the upper edge of the first fitting groove 71 and the second fitting groove 72 of the outer sleeve 70. When the rotating member 40 receives the force of the gas and is supported upward to rotate, compressive elasticity is generated in the spring 60. When the support force of the rotating member 40 is released, it returns to zero by the elastic restoring force and resets.

[0017] The second engaging member 30 is formed in a ring shape and includes a first end portion 31 and a second end portion 32 that communicate with each other. The first end portion 31 has a hollow socket portion 311 recessed downward. On the bottom surface of the second end portion 32, a fitting portion 312 formed with the socket portion 311 is recessed. The diameter of the fitting portion 312 is larger than the diameter of the socket portion 311. The first end portion 31 is made to correspond to the second hole groove 221 of the first engaging member 20, and the assembling portion 22 of the first engaging member 20 is fitted. The fitting portion 312 of the second end portion 32 is fitted into the positioning block 51 of the positioning socket member 50.

[0018] A lid cap (not shown) is fitted to the bottom edge where the fitting portion 312 provided at the bottom of the second end portion 32 of the above-mentioned second engaging member 30 and the positioning block 51 of the positioning socket member 50 are fitted. A through hole communicating with the first end portion 31 and the second end portion 32 is formed in the center of the lid cap to communicate with the external air pressure (not shown).

[0019] The rotating member 40 has a shaft rod 41. A perforation 42 is formed at the center of the shaft rod 41. At the bottom of the perforation 42, a T-shaped stopper is coupled to form a pushing surface that evenly receives force. At the top end of the shaft rod 41, there are a rib 44 provided on one side and a pointer 45 provided on the other side. The rib 44 and the pointer 45 are made to correspond in the same horizontal axis direction. The length of the pointer 45 is greater than the length of the rib 44. While the rib 44 and the pointer 45 are brought into contact with and rotated in the rotation grooves of the first spiral step D1 and the second spiral step D2 of the guide portion 24 of the first engaging member 20, they are rotationally position-restrained in the rotation track groove between the first fitting groove 71 and the second fitting groove 72 of the outer sleeve 70 and rotated synchronously with the shaft rod 41. At the same time, the shaft rod 41 of the rotating member 40 is rotatably coupled so as to be able to rotate within the central guide hole 23 of the first engaging member 20. When air pressure enters, the pointer 45 coupled to the top end can rotate synchronously along the spiral groove.

[0020] The T-shaped stopper coupled to the bottom end of the above-described rotating member 40 may be a screw head, or the bottom end of the above-described rotating member 40 and the T-shaped stopper may be connected and integrated to form a lead screw.

[0021] The rib 44 and the pointer 45 provided on both sides of the top end of the shaft rod 41 of the above-described rotating member 40 respectively correspond in the same horizontal axis direction and correspond to the first angles (lower positions) 2411, 2421 of the first arc cut surface 241 and the second arc cut surface 242 of the first engaging member 20. The preset position is the position where it returns to zero. The rib 44 and the pointer 45 are positioned at the second angles (higher positions) 2412, 2422 of the first arc cut surface 241 and the second arc cut surface 242 of the first engaging member 20 and are preset to move in position when filled with gas.

[0022] The rib 44 and the pointer 45 at the top end of the shaft rod 41 of the rotating member 40 described above correspond in the same horizontal axis direction. When outside air is introduced through the vent hole 53 of the positioning block 51 of the positioning socket member 50, the rib 44 and the pointer 45 support and expand to open the elastic member 52, push up the bottom of the rotating member 40, and the rib 44 and the pointer 45 are in the spiral grooves of the first spiral stage D1 and the second spiral stage D2 of the first arc cut surface 241 and the second arc cut surface 242 on the corresponding side of the guide portion 24 of the first engaging member 20, and are synchronously position-constrained and moved. The rib 44 is slid upward from bottom to top along the first spiral stage D1 from the first angle (lower position) 2411 to the second angle (higher position) 2412 of the first arc cut surface 241, and the pointer 45 is slid upward from bottom to top along the second spiral stage D2 from the first angle (lower position) 2421 to the second angle (higher position) 2422 of the second arc cut surface 242.

[0023] The positioning socket member 50 includes a positioning block 51 and an elastic member 52. The positioning block 51 is reverse T-shaped, and a vent hole 53 penetrating the first end 31 and the second end 32 of the second engaging member 30 is formed at the center. It is fitted and positioned in the fitting portion 312 of the second engaging member 30, and a lid cap having a through hole at the center is fitted to the bottom (not shown). The elastic member 52 is used as a lid cap made of an elastic material, and an open end is formed at one end (bottom end) to be fitted on the vent hole 53 formed at the upper end of the positioning block, forming an elastically expandable lid cap. The other end (top end) abuts against the bottom end of the rotating member 40, and a corrugated bending stage 521 that can be expanded and contracted and folded is provided on the outer peripheral side. When air pressure is injected into the internal space by an air pressure source, the corrugated bending stage 521 on the outer peripheral side of the elastic member 52 that can be expanded and contracted and folded is extended upward, conducting the power of the acting force upward, actuating the elastic member 52 upward. When the air pressure of the air pressure source is insufficient and the gas in the internal space leaks, the corrugated bending stage 521 on the outer peripheral side that can be expanded and contracted and folded contracts downward and returns to the folded state, conducting the power of the downward acting force, and the volume space of the elastic member 52 is compressed and descends.

[0024] At corresponding positions between the positioning block 51 of the positioning socket member 50 described above and the assembling portion 22 of the first engaging member 20, a fitting portion 54 is provided in contact, and the first engaging member 20 and the second engaging member 30 described above are engaged and connected vertically. A clamping space B is formed between the engaging portion 21 of the first engaging member 20 and the first end portion 31 of the second engaging member 30, and the surface of the air pressure detection object 200 is clamped and fixed by the clamping space B. For example, after being fixedly provided on the surface of an object such as a sports shoe, casual shoes, or an airbag that can be filled with gas, when the airbag filled with gas inside is connected to the through hole 331 of the second engaging and abutting portion 33, a barometer capable of showing the air pressure value is attached to the air pressure detection object 200.

[0025] When actually operating and using, as shown in FIGS. 4 to 6, by detachably engaging the first engaging member 20 and the second engaging member 30 vertically, the barometer 100 can be quickly attached onto the assembly hole of the air pressure detection object 200 having an airbag X inside. The air pressure detection object 200 of the present embodiment is a shoe body, but of course, it is not limited to this only. Connect the airbag X inside the air pressure detection object 200 (for example, a shoe body) to the vent hole 53 of the positioning block 51 in the fitting portion 312 of the second end portion 32 of the second engaging member 30 provided at the bottom of the barometer 100. When filling the airbag X inside the air pressure detection object 200 (for example, a shoe body) with gas or pressurizing it with an external air pressure pump and sending the air pressure into the internal airbag X (not shown), the air pressure enters from the vent hole 53 of the positioning block 51 of the positioning socket member 50 of the barometer 100. The elastic member 52 of the positioning socket member 50 receives the acting force of the air pressure and supports it to open upward, spreading the wavy bent step portion 521 upward. At the same time, the bottom of the rotating member 40 is pressed upward by the expansion tension of the elastic member 52. The same horizontal axis direction ribs 44 and the pointer 45 are provided on both sides of the top end of the rotating member 40, respectively, from the first angles (low positions) 2411, 2421 of the first arc cut surface 241 and the second arc cut surface 242 to the spiral grooves of the first spiral step portion D1 and the second spiral step portion D2 of the second angles (high positions) 2412, 2422 from bottom to top, and rotated upward (in the clockwise direction in this embodiment), slid upward. As the pointer 45 rotates with the air pressure, an air pressure scale numerical table is installed on the top surface of the first hole groove 211 of the first engaging member 20, and it is converted into a visualized air pressure value and shown according to the rotation width of the pointer 45, quickly detecting the air pressure value to be transported. According to the needs of the user, after filling the gas and pressurizing it to a predetermined pressure value, the gas filling is stopped, and the gas filling for the air pressure detection object 200 is completed. After using it for a certain period of time, as the air pressure indicated by the pointer of the barometer 100 drops, gas filling is performed at any time, and the air pressure inside the internal airbag X becomes saturated and reaches an optimal use state.

[0026] In this embodiment, by connecting the first engaging member 20 and the second engaging member 30 vertically, the barometer 100 can be quickly attached to the air pressure detection object 200. The shaft rod 41 at one end (the bottom end) of the rotating member 40 is inserted into the central guide hole 23 of the first engaging member 20, and the pointer 45 and the rib 44 at one end (the top end) are brought into contact with the spiral groove of the guide portion 24 of the first engaging member 20. Utilizing the elastic member 52 of the positioning socket member 50, the open end is fitted into the vent hole 53 of the positioning block 51, and the closed end is brought into contact with the bottom of the shaft rod 41 of the rotating member 40. The air pressure is introduced through the vent hole 53 of the positioning socket member 50. When the gas is filled, it supports and expands the elastic member 52 to open it and pull it up, conducting the power to form an upward acting force, actuating the elastic member 52 upward and pushing the rotating member 40 upward. The rib 44 and the pointer 45 in the same horizontal axis direction are provided at the top end of the rotating member 40, and it is rotated upward along the spiral groove. When the gas leaks, the expandable and foldable corrugated folding step portion 521 on the outer peripheral side contracts downward and returns to the folded state, conducting the power to form a downward acting force, compressing and lowering the volume space of the elastic member 52 to indicate the gas pressure value. By simplifying the detection structure to be assembled, it prevents the conventional mechanical barometer structure from being too complex to assemble and maintain, and from being damaged due to human factors during disassembly. The structure is simple, easy to assemble, easy to maintain, and can accurately indicate the gas pressure value.
