Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, specifically a wireless digital pressure gauge with waterproof function. Background Technology

[0002] A wireless digital pressure gauge is a modern measuring tool used to monitor and display the pressure of gases or liquids. Unlike traditional mechanical pressure gauges, wireless digital pressure gauges convert the detected pressure value into an electrical signal through a built-in sensor and transmit the data to a remote monitoring system or mobile device via wireless communication technologies (such as Bluetooth, Wi-Fi, LoRa, NB-IoT, etc.), allowing users to view and analyze the data in real time. Because wireless digital pressure gauges are often used in environments where they come into contact with water or are used outdoors, they are typically manufactured with waterproof structures, such as rubber rings and sealing structures, giving them a certain degree of water resistance and preventing water from entering the internal electronic components and causing damage.

[0003] For example, patent CN219996415U discloses a waterproof rotary wireless digital pressure gauge, including a gauge body, and further including: a rotary joint fixedly connected to the gauge body; a sensor fixedly inserted into the rotary joint; a first rubber ring fixedly sleeved on the sensor, with the outer wall of the first rubber ring and the inner wall of the rotary joint in contact; a battery back cover fixedly connected to the gauge body; and a shaped rubber ring disposed between the battery back cover and the gauge body. This utility model solves the problem of water leakage caused by incomplete contact between the rubber ring and the battery back cover in the prior art by directly adding a set of shaped rubber rings to the gauge body and the battery back cover, and by the conical surface of the shaped rubber rings being tightly attached to the battery back cover, thereby increasing the contact area during compression deformation.

[0004] However, the pressure gauges in the above technology still have the following problems:

[0005] Although the wireless digital pressure gauge has a certain degree of water resistance due to mechanisms such as rubber rings, the signal antenna of the wireless digital pressure gauge has a certain length, which brings some inconvenience to its storage and carrying. Furthermore, the antenna extends to the outside of the title of the wireless digital pressure gauge, making it prone to collisions with external objects during use, which may lead to bending or even breakage, causing signal transmission failure of the wireless digital pressure gauge. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a waterproof wireless digital pressure gauge. For example, the antenna of the wireless digital pressure gauge can be stored, thereby preventing the antenna from being damaged by collisions with external objects during carrying, improving the stability of the wireless digital pressure gauge and preventing signal transmission failures.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof wireless digital pressure gauge, comprising a gauge body, a storage groove on the back side of the gauge body, the top of the storage groove being through-hole, symmetrically arranged rotating holes on both sides of the top of the storage groove, a rotating shaft rotatably connected to each of the two rotating holes, a connecting rod fixedly connected between the two rotating shafts, an antenna connected to the side of the connecting rod, the diameter of the antenna being smaller than the cross-sectional length and width of the storage groove, a limiting component connected to the inner wall of the end of the storage groove away from the connecting rod, and the limiting component being connected to the end of the antenna.

[0008] Furthermore, an internal threaded ring is fixedly connected to the front side of the watch body, and a transparent cover is connected to the end of the internal threaded ring away from the watch body. An external threaded ring is fixedly connected to the side of the transparent cover close to the internal threaded ring, and the external threaded ring is threadedly connected to the internal threaded ring.

[0009] Furthermore, each of the two rotating holes has a spring hole at one end that is far apart from each other. The inner walls of the two spring holes are connected to torsion springs. The two torsion springs are respectively fitted onto two rotating shafts. One end of the torsion spring is fixedly connected to the adjacent rotating shaft, and the other end is fixedly connected to the adjacent spring hole.

[0010] Furthermore, a connecting rod is fixedly connected to one side of the connecting round rod, and an internal threaded hole is opened at the end of the connecting rod away from the connecting round rod. An external threaded block is fixedly connected to the end of the antenna close to the connecting round rod, and the external threaded block is threadedly connected to the internal threaded hole.

[0011] Furthermore, the antenna consists of an outer shell and an inner wire. The inner wire is located inside the outer shell. One end of the inner wire passes through an external threaded block and is connected to a first contact piece. A second contact piece is fixedly connected to the bottom of the internal threaded hole. The first contact piece and the second contact piece abut against each other. The second contact piece is connected to the internal control circuit of the meter body through a signal line passing through a connecting rod, a connecting round rod, and a rotating shaft on one side.

[0012] Furthermore, the limiting component includes a limiting block, two sliders, and two limiting springs. The end of the receiving groove away from the connecting round rod has a telescopic groove, and both sides of the telescopic groove have limiting grooves. The limiting block is slidably connected to the telescopic groove. The two sliders are fixedly connected to the two sides of the limiting block away from the antenna, respectively. The two sliders are slidably connected to the two limiting grooves, respectively. One end of each of the two limiting springs is fixedly connected to the two sliders, and the other end is fixedly connected to the limiting grooves.

[0013] Furthermore, a limiting rod is fixedly connected to the inner wall of one end of the limiting groove, and the other end of the limiting rod passes through the inner walls of the adjacent slider and the limiting spring in sequence, and is fixedly connected to the inner wall of the other end of the limiting groove.

[0014] Furthermore, the limiting block has inclined surfaces on both sides near the antenna end.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This waterproof wireless digital pressure gauge features a rotating shaft and storage slot design, allowing the antenna at the top of the gauge to be stored in the slot when not in use, thus preventing damage to the antenna during movement or transport. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Please see Figure 1 - Figure 8 A waterproof wireless digital pressure gauge includes a gauge body 1. A storage groove 101 is provided on the back side of the gauge body 1. The top of the storage groove 101 is through-hole. Symmetrically arranged rotating holes 102 are provided on both sides of the top of the storage groove 101. A rotating shaft 2 is rotatably connected in each of the two rotating holes 102. A connecting rod 3 is fixedly connected between the two rotating shafts 2. An antenna 4 is connected to the side of the connecting rod 3. The diameter of the antenna 4 is smaller than the cross-sectional length and width of the storage groove 101. A limiting component is connected to the inner wall of the end of the storage groove 101 away from the connecting rod 3. The limiting component is connected to the end of the antenna 4.

[0028] like Figure 1 - Figure 8 As shown, the waterproof wireless digital pressure gauge of this invention is structurally similar to existing waterproof wireless digital pressure gauges, such as the waterproof rotary wireless digital pressure gauge disclosed in patent CN219996415U. The main improvement of this invention lies in enhancing the stability of the antenna 4 on the gauge body 1 and reducing the risk of damage from impacts to the antenna 4. Figures 1 to 8 As shown, the waterproof wireless digital pressure gauge of this utility model allows the antenna 4 to be rotated within the storage slot 101 via the connecting rod 3 and the rotating shafts 2 at both ends. This allows the antenna 4 to be flipped over and stored in the storage slot 101 when not in use. The limiting component limits the stored antenna 4 to prevent it from flipping out of the storage slot 101, thus protecting the antenna 4 from collisions and damage from the outside.

[0029] like Figure 1 - Figure 3 As shown, an internal threaded ring 5 is fixedly connected to the front side of the watch body 1. A transparent cover 6 is connected to the end of the internal threaded ring 5 away from the watch body 1. An external threaded ring 7 is fixedly connected to the side of the transparent cover 6 closest to the internal threaded ring 5. The external threaded ring 7 is threadedly connected to the internal threaded ring 5. Through the connection between the external threaded ring 7 and the internal threaded ring 5, the transparent cover 6 can be placed over the front end of the watch body 1, thereby allowing the data on the front side of the watch body 1 to be observed while preventing external water stains from entering the interior of the watch body 1 and causing damage to the watch body 1.

[0030] like Figure 6 - Figure 8 As shown, each of the two rotating holes 102 has a spring hole 103 at one end that is far apart from the other. A torsion spring 8 is connected to the inner wall of each spring hole 103. Two rotating shafts 2 are respectively fitted onto the two torsion springs 8. One end of the torsion spring 8 is fixedly connected to the adjacent rotating shaft 2, and the other end is fixedly connected to the adjacent spring hole 103. Through the action of the torsion spring 8, in conjunction with the rotating shaft 2, the antenna 4 can always be ejected outwards, thus preventing the antenna 4 from flipping erratically.

[0031] like Figure 6 - Figure 8 As shown, a connecting rod 9 is fixedly connected to one side of the connecting rod 3. An internally threaded hole 901 is provided at the end of the connecting rod 9 furthest from the connecting rod 3. An externally threaded block 10 is fixedly connected to the end of the antenna 4 closest to the connecting rod 3, and the externally threaded block 10 is threadedly connected to the internally threaded hole 901. The connection between the externally threaded block 10 and the internally threaded hole 901 of the connecting rod 9 facilitates the disassembly and installation of the antenna 4 on the connecting rod 3, and allows for the replacement of the damaged antenna 4 if it is damaged and affects signal transmission.

[0032] like Figure 8 As shown, the antenna 4 consists of a housing 41 and an inner wire 42. The inner wire 42 is located inside the housing 41. One end of the inner wire 42 passes through the external threaded block 10 and is connected to a first contact piece 43. A second contact piece 91 is fixedly connected to the bottom of the internal threaded hole 901. The first contact piece 43 and the second contact piece 91 abut against each other. The second contact piece 91 is connected to the internal control circuit of the meter body 1 via a signal line passing through the connecting rod 9, the connecting round rod 3, and the rotating shaft 2 on one side. The housing 41 of the antenna 4 can protect the inner wire 42. When the antenna 4 is installed, the inner wire 42 is connected and transmits signals through the contact between the first contact piece 43 and the second contact piece 91 in the internal threaded hole 901.

[0033] like Figure 4 and Figure 5 As shown, the limiting assembly includes a limiting block 11, two sliders 12, and two limiting springs 13. The end of the receiving groove 101 away from the connecting round rod 3 has a telescopic groove 104. Limiting grooves 105 are provided on both sides of the telescopic groove 104. The limiting block 11 is slidably connected to the telescopic groove 104. The two sliders 12 are fixedly connected to the two sides of the end of the limiting block 11 away from the antenna 4, respectively. The two sliders 12 are slidably connected to the two limiting grooves 105, respectively. One end of the two limiting springs 13 is fixedly connected to the two sliders 12, and the other end is fixedly connected to the limiting grooves 105, respectively. When storing the antenna 4, the two limiting springs 13 always push the two sliders 12 upward and drive the limiting block 11 to move upward, thereby pressing the end of the antenna 4 against the storage groove 101 to prevent the antenna 4 from popping out of the storage groove 101. When it is necessary to release the antenna 4 from the storage groove 101, the limiting block 11 can be pressed down and slid into the telescopic groove 104 to release the antenna 4, which will then automatically pop out of the storage groove 101 by the torsion spring 8.

[0034] like Figure 4 and Figure 5As shown, a limiting rod 14 is fixedly connected to the inner wall of one end of the limiting groove 105. The other end of the limiting rod 14 passes through the inner walls of the adjacent slider 12 and the limiting spring 13 in sequence, and is fixedly connected to the inner wall of the other end of the limiting groove 105. The limiting rod 14 can prevent the limiting spring 13 from being squeezed and deformed or twisted when it is compressed, thereby improving the stability of the limiting structure.

[0035] like Figure 4 and Figure 5 As shown, the limiting block 11 has inclined surfaces on both sides near the antenna 4. The inclined surfaces on both sides of the top of the limiting block 11 can block the antenna 4. During the process of storing the antenna 4, when the end of the antenna 4 comes into contact with the inclined surface on the outside of the limiting block 11, the limiting block 11 can be squeezed and retracted downwards, making it more convenient and faster to use.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
