[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3As shown, this utility model provides an embedded pressure gauge, including a gauge body 1. A protective device 2 is fixedly installed on the top of the gauge body 1, and a connecting device 3 is threadedly connected to the bottom of the gauge body 1. A pipe body 4 is fixedly connected to the bottom of the connecting device 3. The connecting device 3 includes a male connector 31 and a female connector 32. The bottom of the female connector 32 is fixedly connected to the outer surface of the pipe body 4. Connecting heads 36 are fixedly snapped between the inner walls of the male connector 31 and the female connector 32. A second spring 37 is sleeved on the outer surface of each of the two connecting heads 36. A conical opening 30 is opened at one end of the male connector 31 and the female connector 32. One end of each of the two connecting heads 36 abuts against the outer surface of the conical opening 30. Multiple steel balls 35 are embedded between the inner walls of the top of the female connector 32. The outer surface of the female connector 32 is opened... There is an annular groove 38, and multiple steel balls 35 work together with the annular groove 38. One end of the female head 32 is slidably sleeved with a sliding collar 34. A first spring 33 is sleeved on the outer surface of the female head 32. One end of the first spring 33 is fixedly connected to one end of the sliding collar 34. It can be connected by inserting the male head 31 into the female head 32. The connection and fixation are achieved by the engagement of multiple steel balls 35. During the fixation process, the two connecting heads 36 abut against each other. The abutting force causes the two connecting heads 36 to retract and move in opposite directions through the second springs 37. The two retracted second springs 37 disengage from the two conical openings 30, thereby opening the valve. When the two connecting heads 36 no longer abut against each other, they reset and abut against the conical openings 30 to close the valve.

[0016] The protective device 2 includes a fixed base 20, the bottom end of which is fixedly connected to the outer surface of the instrument body 1. A connecting plate 22 is fixedly connected to one side of the top of the fixed base 20. An adjustment groove 23 is provided on the outer surface of the connecting plate 22. Two bolts 24 are inserted through the top of the fixed base 20, and both bolts 24 pass through the adjustment groove 23. A protective shell 21 is fixedly connected to the top of the connecting plate 22. The operator can rotate the two bolts 24 to make the connecting plate 22 fit and fix it to the top of the fixed base 20. Loosening the two bolts 24 can move the protective shell 21 a certain distance through the adjustment groove 23, which helps to adjust the coverage area of ​​the protective shell 21. This serves to protect the instrument body 1 below the protective shell 21, making it convenient for the operator to install and remove the protective shell 21, strengthening the protection of the instrument body 1, preventing the entry of dust and moisture from the top, and reducing the impact of direct sunlight on the instrument.

[0017] A connecting tube is fixedly connected to the bottom of the meter body 1. The connecting tube is threaded to the top of the male connector 31. A cable output end 10 and an L-shaped communication antenna 11 are fixedly connected to one end of the meter body 1. Multiple steel balls 35 are arranged in a ring array. The diameter of one end of the male connector 31 is the same as the inner diameter of one end of the female connector 32. The outer surface of the male connector 31 slides against the inner wall of the female connector 32. The setting of the connecting tube facilitates the operator to disassemble the connecting device 3 separately, which is convenient for maintenance. The cable output end 10 and the L-shaped communication antenna 11 facilitate the connection of the cable and the transmission of pressure data, realizing data cloud computing. The steel balls 35 arranged in a ring array are for the purpose of connecting and fixing the male connector 31 and the female connector 32 by engaging with the ring slot 38, which plays a role in connection limit. The male connector 31 and the female connector 32 of the same diameter are for the purpose of making the connection of the male connector 31 and the female connector 32 more snug and smooth, and preventing gas leakage after connection.

[0018] The protective shell 21 is set at an inclined angle at both ends and is made of stainless steel. The outer surfaces of the two bolts 24 slide against the outer surface of the adjustment groove 23. The inclined protective shell 21 can effectively guide the flow of dust and rainwater on both sides. The stainless steel material can prevent the protective shell 21 from corroding or rusting. The two adjustment grooves 23 slide against the adjustment groove 23, which can reduce the friction on the outer surface of the adjustment groove 23 and facilitate the movement of the connecting plate 22 through the adjustment groove 23.

[0019] Working principle: When it is necessary to connect the pipe body 4, the operator drags the sliding collar 34 downwards, causing the sliding collar 34 to slide downwards and disengage from the ring-shaped array of steel balls 35 via the first spring 33. At this time, the male head 31 is inserted between the inner walls of one end of the female head 32. When one end of the male head 31 abuts against one end of the female head 32, the multiple steel balls 35, no longer obstructed by the sliding collar 34, simultaneously engage with the annular groove 38, thereby achieving the connection and fixation between the female head 32 and the male head 31. At this time, one end of the two connectors 36 between the male connector 31 and the female connector 32 abuts against each other. Under the action of the abutment, with the help of the second spring 37, the two connectors 36 are disengaged from the conical openings 30 at one end of the male connector 31 and the female connector 32 respectively, so that the gas flows through the conical openings 30 at both ends. Then, the sliding collar 34 is released so that the sliding collar 34 is reset under the action of the first spring 33. The inner wall of the sliding collar 34 closes the multiple steel balls 35 again, thereby realizing the quick connection and fixation of the pipe body 4.

[0020] When the protective device 2 needs to be installed, the connecting plate 22 at the bottom of the protective shell 21 is attached to the top side of the fixing seat 20. The operator can use two bolts 24 to pass through the connecting plate 22 and rotate the nut to connect and fix the connecting plate 22 to the top side of the fixing seat 20, thereby achieving the connection and fixation of the protective shell 21. The operator can loosen the two bolts 24 to move the protective shell 21 a certain distance through the adjustment groove 23 on the surface of the connecting plate 22, thereby facilitating the adjustment of the coverage area of ​​the protective shell 21.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
