A structure of a conventional flowmeter 1 is disclosed in taiwan patent publication No. M398628 entitled "improvement of flowmeter" of the related art, which is a structure of a conventional flowmeter 1. As shown in fig. 1 and fig. 2, the flowmeter 1 includes a transparent base 10, a first fixing component 11, a second fixing component 12, a positioning piece 13, a pressing piece 14, a flow rate scale 15 and an adjusting piece 16. Wherein, a containing chamber 101 is provided below the transparent base 10, the containing chamber 101 is provided with an inlet end 102, an outlet end 103, and a flow channel 104 connecting and penetrating the inlet end 102 and the outlet end 103, the flow channel 104 penetrates the side 105 of the transparent base 10 due to the process relationship and is provided with a guide slot 1051 and a through hole 106 with internal threads, an indication ball 107 is provided inside the flow channel 104, a flow scale 15 is embedded in the concave portion 108 above the transparent base 10, a user can directly see the liquid flowing status through the outside of the transparent base 10 by the indication ball 107 and the flow scale 15, and a plurality of screw holes 1011 are respectively provided at the front and rear ends of the lower side of the two side frames of the transparent base 10. The first fixing component 11 has a first fixing member 111 extending toward the inlet end 102 and engaging with the inlet end 102, and an end of the first fixing member 111 away from the inlet end 102 has a first inner screw hole 110 for screwing a water inlet pipe (not shown) with the first inner screw hole 110. The second fixing assembly 12 has a second fixing member 121 extending toward the outlet end 103 and engaging with the outlet end 103, and a second inner screw hole 120 is formed at an end of the second fixing member 121 away from the outlet end 103 for screwing a water outlet pipe (not shown) with the second inner screw hole 120. The two sides of the positioning plate 13 are respectively bent to form a connecting section 130 fixed toward the two inner sides of the accommodating chamber 101 of the transparent base 10, two ends of the connecting section 130 are respectively provided with a fixing hole 1300 corresponding to the screw hole 1011 of the transparent base 10, a plurality of fixing members 1301 are respectively inserted into the fixing holes 1300 through the screw hole 1011, two ends of the positioning plate 13 are respectively provided with a first hole 131 corresponding to the inlet end 102 and a second hole 132 corresponding to the outlet end 103, the first hole 131 is provided with an upper section of the first fixing member 111, the second hole 132 is provided with an upper section of the second fixing member 121, and the first hole 131 and the upper section of the first fixing member 111 and the second hole 132 and the upper section of the second fixing member 121 are respectively fixed by welding. The pressing member 14 is extended toward one end of the transparent base 10 to form a pressing rod 141, which penetrates through the flow channel 104 and presses against the indicating ball 107, so that the indicating ball will not flow out, and the fastening member 142 is inserted from the guide groove 1051 and blocked outside the through hole 106, so as to enhance the anti-leakage function. The flow rate scale 15 is disposed in the recess 108 above the transparent base 10. The adjusting member 16 is screwed with the first fixing member 111, and the adjusting member 16 can adjust the height range of the liquid flow to limit the liquid flow.

The existing flowmeter 1 is easy to have the following disadvantages after being used:

1. since the contact surface of the joint section 130 on both sides of the spacer 13 of the flowmeter 1 is small, so that the connecting section 130 can increase the strength above the two side frames of the transparent base 10, however, when the connecting sections 130 are respectively inserted into the accommodating chamber 101 of the transparent base 10, and because the distance between the screw holes 1011 of the transparent base 10 and the upper portions of the two side frames of the transparent base 10 is short and the stress is concentrated, when the fixing members 1301 fix the joint section 130 to the inner sides of the two side frames of the transparent base 10, if the force applied by the screw-in of the fixing member 1301 is too large, the fixing member is easily cracked at the distance between the upper side of the screw hole 1011 and the two side frames of the transparent base 10, so that the supporting force of the joint section 130 of the positioning plate 13 is not enough, meanwhile, the bonding strength between the bonding segment 130 and the frame edges on both sides of the transparent base 10 is not good.

2. Since the end of the first fixing member 111 of the flowmeter 1 is inserted into the first hole 131 of the positioning plate 13, the end of the second fixing member 121 is inserted into the second hole 132 of the positioning plate 13, and then the first hole 131 and the upper section of the first fixing member 111 and the second hole 132 and the upper section of the second fixing member 121 are fixed by welding, respectively, to prevent the water inlet pipe from rotating when screwed from the first inner screw hole 110 and prevent the water outlet pipe from rotating when screwed from the second inner screw hole 120, so that the first fixing member 111 and the second fixing member 121 are respectively sleeved in the transparent seat 10, and the flowmeter 1 can be fixed on a machine. However, since the shapes of the middle sections and the lower sections of the first fixing member 111 and the second fixing member 121 are circular, when the water inlet pipe and the water outlet pipe are screwed, the middle sections and the lower sections of the first fixing member 111 and the second fixing member 121 also rotate, it is difficult to confirm that the locking between the water inlet pipe and the first fixing member 111 and between the water outlet pipe and the second fixing member 121 is achieved, and the water inlet pipe and the water outlet pipe continue to rotate towards the bottom ends inside the first inner screw hole 110 and the second inner screw hole 120, so that the bottom ends inside the first inner screw hole 110 and the second inner screw hole 120 are cracked due to the water inlet pipe and the water outlet pipe being rotated too much, thereby affecting the structural strength of the locking body 10 of the transparent fixing member, further reducing the service life of the flowmeter 1, and further causing a small cost burden to users.

In view of the above problems of the conventional flowmeter 1 structure, such as insufficient supporting force of the joint section 130 of the positioning plate 13, and the bottom ends of the first inner screw hole 110 and the second inner screw hole 120 are cracked when the water inlet pipe and the water outlet pipe are rotated, the inventors of the present invention further developed a locking structure of a regulating valve of a flowmeter of taiwan patent publication No. M446324, as shown in the conventional flowmeter 2 structure shown in fig. 3 and 4, wherein one end of the connecting pipe side of the base body 20 of the flowmeter 2 is provided with a screw hole 201 communicating with the inside of the flowmeter 2, the screw hole 201 is provided with a connecting rib 202 facing the inside and a screw fixing portion 203 connected with the connecting rib 202 and having a screw fixing hole 204, a regulating valve 21 is screwed into the screw hole 201, the regulating valve 21 comprises a regulating shaft 210 and a regulating button 23 connected with the regulating shaft 210, and a convex ring 211 and a screw head 212 are extended from one end of the regulating shaft 210, and a positioning member 22 fixed to the screw head 212, and engaged with the other end of the adjusting valve 21 through the adjusting button 23, and the external thread portion 2100 of the adjusting shaft 210 is screwed to the screw hole 201 of the seat body 20, wherein one end of the positioning member 22 has a socket plate 221, the socket plate 221 has a socket hole 220 to match the screw head 212 of the adjusting valve 21, the socket plate 221 abuts against the upper side of the convex ring 211 and is fixed to the screw head 212, and two sides of a positioning plate 222 at the other end of the positioning member 22 respectively extend toward the inside of the seat body 20 to form a baffle 223, the positioning plate 222 has a through hole 224 corresponding to the screw hole 204, and the through hole 224 can match a screw 225 to penetrate an object to be fixed on site, and then penetrate the through hole 224 and form a screw fixation with the screw hole 204.

The conventional flowmeter 2, when used, has the following problems:

because the force-bearing contact surfaces of the baffle plates 223 on the two sides of the positioning plate 222 at the other end of the positioning member 22 are small, the baffle plates 223 are only limited above the two inner sides of the frame edges 200 on the two sides of the seat body 20, and the design structure of the baffle plates 223 is only leaned against the two inner sides of the frame edges 200 on the two sides of the seat body 20 and is not locked, when the internal thread hole 213 of the screw head 212 of the adjusting valve 21 is screwed with a water inlet pipe, the hexagonal trepanning 220 of the socket plate 221 can limit the adjusting valve 21 to be continuously screwed into the screw head 212, although the trepanning 220 can improve the problems that the shapes of the middle section and the lower section of the first fixing member 111 and the second fixing member 121 in the existing flowmeter 1 are all round, and the water inlet pipe and the water outlet pipe can also rotate when screwed, but when the interior of the screw head 212 is rotated by applying force through the water inlet pipe, the rotating force will press one of the baffles 223 to cause the upper position 205 of one of the rims 200 of the base body 20 to collapse or crack, which is not favorable for the overall connection strength of the flowmeter 2 and affects the structures on both sides of the rims 200 of the base body 20 of the flowmeter 2.

Disclosure of Invention

In view of the above problems, the present invention provides a reinforced structure of a flow meter adapter tube to overcome the disadvantages of the prior art that if the screw head of the flow meter 2 rotates through a water inlet tube, the rotating force will press one of the baffles to break or crack the upper position of one of the frame edges of the seat body. The invention mainly aims to disclose a strengthening structure of a flow meter connecting pipe, which utilizes the vertical baffle plates which are arranged at two sides of the positioning unit and at least extend into two inner sides of two frame edges of the transparent seat body and have half height and large contact surface to respectively abut against and fixedly limit the two inner sides of the two frame edges of the transparent seat body of the flow meter, but can not rotate, so that the supporting force of the positioning unit sleeved and fixedly arranged on the first locking solid body and the second locking solid body is strengthened, and the pipe connecting side strength of the transparent seat body is strengthened.
