[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a flow monitoring device. In this embodiment, a control component 204 is provided. The control component 204 clamps and fixes the wiring terminals and connects them when the flow monitoring device is in use.

[0030] Specifically, the mounting assembly 100 includes a housing 101, a receiving cavity 102 disposed inside the housing 101, and a cover plate 103 disposed at the end of the housing 101. A locking pin 103a is disposed on the end face of the cover plate 103, and a locking block 103b is disposed on the end face of the locking pin 103a; and...

[0031] The push clamping assembly 200 includes a locking member 201 disposed on the inner wall of the housing 101, a fixing member 202 disposed on the inner wall of the housing 101, a placement member 203 disposed on the inner wall of the fixing member 202, a control member 204 disposed on the inner wall of the fixing member 202, and a clamping member 205 disposed on the inner wall of the fixing member 202.

[0032] The locking member 201 is disposed in the first mounting groove 101a on both sides of the housing 101, and the fixing member 202 is arranged in the first moving groove 101a-1 on the bottom plate inside the housing 101. The fixing member 202 can move within the first moving groove 101a-1. The placement member 203 and the clamping member 205 together clamp the terminal block.

[0033] In summary, during use, when the cover plate 103 is closed, the locking pin 103a on the end face of the cover plate 103 extends into the first mounting groove 101a to lock it, fixing the cover plate 103 above the housing 101. At the same time as the cover plate 103 is locked, it will push the first push rod 101c on the end face of the bottom plate inside the housing 101. When the first push rod 101c moves to the right, it will push the fixing member 202 forward. At this time, when the fixing member 202 moves forward, it will clamp the wiring terminal above the fixing member 202 and connect the wiring terminal to the interface of the electrical components inside the housing 101.

[0034] Example 2

[0035] Reference Figures 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, except that when the locking pin 103a enters the first mounting groove 101a, it pushes the first pushing rod 101c to move to the right, and at the same time pushes the fixing frame 202a to move forward, while clamping the wiring terminal.

[0036] Specifically, the outer wall of the housing 101 is provided with a first mounting groove 101a, the end face of the first mounting groove 101a is provided with a sliding groove 101a-1, and the inner wall of the first mounting groove 101a is provided with a locking groove 101a-2. Among them, the first mounting groove 101a is provided on both walls of the housing 101, and two first mounting grooves 101a are provided on each wall.

[0037] Preferably, the end of the housing 101 is provided with a pushing groove 101b, the outer wall of the pushing groove 101b is provided with a first moving groove 101b-1, the inner wall of the first moving groove 101b-1 is provided with a limiting groove 101b-2, the inside of the pushing groove 101b is provided with a first pushing rod 101c, the end of the first pushing rod 101c is provided with a pushing block 101c-1, and the outer wall of the first pushing rod 101c is provided with an array of protrusions 101c-2.

[0038] The push groove 101b is located on the bottom plate end face inside the housing 101. The push groove 101b is connected to the first first mounting groove 101a on the left side. The housing 101 on the left side has a slot, so that the push block 101c-1 located in the first mounting groove 101a can move to the right from the slot.

[0039] The locking member 201 includes a locking rod 201a disposed on the inner wall of the locking groove 101a-2, a locking tooth 201a-1 disposed on the end face of the locking rod 201a, a first elastic member 201a-2 disposed on the outer wall of the locking rod 201a, and a second push rod 201a-3 disposed at the end of the locking rod 201a. One end of the second push rod 201a-3 extends to the outer wall of the housing 101 and is provided with a button.

[0040] The locking rod 201a is hinged inside the locking groove 101a-2. The locking teeth 201a-1 are provided on the outer wall of the locking rod 201a. The upper end is inclined, and the smooth surface is provided below the locking teeth 201a-1. The first elastic element 201a-2 is provided between the locking rod 201a and the locking groove 101a-2. Pushing the lower end of the locking rod 201a to the right, the lower end of the locking rod 201a can be moved to the left by pressing the button.

[0041] Preferably, the locking member 201 further includes a spring plate 201b, the outer wall of the spring plate 201b is provided with a slider 201b-1, the slider 201b-1 is inserted into the slide groove 101a-1 and slides therewith, the end of the spring plate 201b is provided with a spring post 201b-2, and the outer wall of the spring post 201b-2 is sleeved with a second elastic member 201b-3.

[0042] The spring plate 201b has sliders 201b-1 on both sides, which slide within the groove 101a-1. The spring plate 201b is connected to a spring post 201b-2 at its end. The bottom of the spring post 201b-2 is semi-circular. The second elastic element 201b-3, which is sleeved on the outside of the spring post 201b-2, is located between the spring plate 201b and a fixed plate in the first mounting groove 101a. When the spring plate 201b is pressed down, the second elastic element 201b-3 receives pressure and is compressed and deformed above the fixed plate.

[0043] In summary, during use, when the cover plate 103 is pressed down, the locking pin 103a on the end face of the cover plate enters the first mounting groove 101a and continues to press down. The locking pin 103a touches the spring plate 201b and drives the spring plate 201b to continue to apply pressure to the second elastic element 201b-3, causing it to deform. At this time, the locking block 103b at the bottom of the locking pin 103a and the locking rod 201a in the locking groove 101a-2 come into contact. When the locking pin 103a is pressed down, the inclined surface of the locking block 103b and the inclined surface of the locking tooth 201a-1 come into contact, squeezing the locking tooth 201a-1, causing the locking rod 201a to... The locking bar retracts to the left into the locking groove 101a-2. Then, the first elastic element 201a-2 pushes the locking rod 201a to the right. At this time, the smooth surface of the lower part of the locking tooth 201a-1 contacts the smooth surface of the upper part of the locking block 103b, so that the locking tooth 201a-1 locks the locking block 103b, preventing the locking pin 103a from moving upward. When the button is pressed, the lower end of the locking rod 201a moves to the left. At this time, the locking tooth 201a-1 loses contact with the locking block 103b. Then, the second elastic element 201b-3 bounces upward, and the return plate 201b drives the locking pin 103a to move upward.

[0044] At the same time, when the locking pin 103a is pressed downward, the semi-circular surface of the lower end of the locking pin 103a and the inclined surface of the pushing block 101c-1 on the left side of the first pushing rod 101c will come into contact, pressing the pushing block 101c-1, causing the first pushing rod 101c to move to the right, and at the same time driving the protrusion 101c-2 on the outer wall of the first pushing rod 101c to move to the right. When the protrusion 101c-2 moves to the right, the protrusion 101c-2 will push the fixed frame 202a forward.

[0045] Example 3

[0046] Reference Figures 3-6 This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that when the fixed frame 202a is pushed forward by the protrusion 101c-2, it will drive the clamping member 205 to clamp the wiring terminal above the fixed frame 202a, and at the same time move forward to connect with the interface of the electrical component.

[0047] Specifically, the fixing component 202 includes a fixing frame 202a, a movable groove 202a-1 is provided on the outer wall of the fixing frame 202a, a moving hole 202a-2 is provided at the end of the fixing frame 202a, a connecting block 202a-3 is provided on the outer wall of the fixing frame 202a, a limit plate 202b is provided at the end of the fixing frame 202a, and a second mounting groove 202c and a second moving groove 202c-1 are provided at the end of the fixing frame 202a.

[0048] The fixed frame 202a has movable grooves 202a-1 on both sides, and the moving hole is set on the bottom plate inside the fixed frame 202a and penetrates the bottom plate. The limiting plates 202b on both sides of the fixed frame 202a are set in the limiting grooves 101b-2, so that the fixed frame 202a can move in the first moving groove 101b. At the same time, the second moving groove 202c-1 opened at the end of the fixed frame 202a is set on both sides of the second mounting groove 202c.

[0049] Preferably, the placement component 203 includes a support rod 203a, a support plate 203a-1 is provided at the end of the support rod 203a, a transmission rod 203b is provided at the end of the support rod 203a, a connecting rod 203c is hinged at the end of the transmission rod 203b, and a fixing rod 203d is hinged at the end of the connecting rod 203c.

[0050] The bearing plate 203a-1 at the end of the bearing rod 203a can be placed in the second mounting groove 202c. The bearing rod 203a has transmission rods 203b on both sides of the outer wall of the part inside the fixed frame 202a. One end of the connecting rod 203c is hinged to the transmission rod 203b, and the other end is hinged to the fixed rod 203d. When the bearing plate 203a-1 moves downward, the bearing rod 203a drives the transmission rod 203b to move downward. At the same time, the transmission rod 203b drives the connecting rod 203c and the fixed rod 203d to move downward.

[0051] The control component 204 includes a mounting base 204a disposed on the end face of the fixed frame 202a. A roller 204b is hinged inside the mounting base 204a, and a transmission gear 204c is disposed on the outer wall of the roller 204b. The roller 204b is a rubber wheel with a certain degree of elasticity and can deform on its own.

[0052] The clamping member 205 includes a slide rail 205a disposed on the end face of the fixed frame 202a. A rack 205b is disposed on the inner wall of the slide rail 205a and slides therewith. The rack 205b meshes with a transmission gear 204c. A first moving rod 205c is hinged to the outer wall of the rack 205b. The slide rail 205a is disposed on the bottom plate of the fixed frame 202a, and its position is close to that of the mounting base 204a. The rack 205b meshes with the transmission gear 204c, and when the transmission gear 204c rotates, it drives the rack 205b to move.

[0053] Preferably, a clamping rod 205d is hinged to the end of the first moving rod 205c, the inner wall of the clamping rod 205d is hinged to the connecting block 202a-3, a second moving rod 205e is hinged to the end of the clamping rod 205d, a clamping plate 205f is provided at the end of the second moving rod 205e, a second slider 205f-1 is provided at the end of the clamping plate 205f, and the second slider 205f-1 slides in the second moving groove 202c-1.

[0054] The clamping rod 205d has a slot in the middle, and the inside of the slot is hinged to the other end of the connecting block 202a-3. The clamping rod 205d moves in the movable slots 202a-1 on both sides of the fixed frame 202a. The top of the clamping rod 205d is hinged to the second moving rod 205e. The second slider 205f-1, which is connected to the bottom of the clamping plate 205f, slides in the second slide groove 202c-1, so that the clamping plate 205f can only move left and right on the second slide groove 202c-1.

[0055] In summary, during use, when the terminal block is placed on the support plate 203a-1, the weight of the terminal block itself causes the support plate 203a-1 to move downwards a certain distance. When the support plate 203a-1 is pressed down, the support rod 203a moves downwards. At this time, the transmission rod 203b moves downwards, driving the connecting rod 203c to move downwards as well. Simultaneously, the connecting rod 203c drives the fixing rod 203d to unfold downwards and to both sides. Since the fixing rod 203d is connected to the clamping rod 205d, the top of the clamping rod 205d will move inwards a small distance to the left and right sides, performing the first step of clamping the terminal block.

[0056] Simultaneously, the protrusion 101c-2 on the outer wall of the first push rod 101c pushes the fixed frame 202a forward within the first moving groove 101b-1. Since the bottom plate of the fixed frame 202a has a moving hole 202a-2, the roller 204b can contact the bottom surface of the first moving groove 101b-1. When the fixed frame 202a moves forward, the roller rotates, simultaneously driving the transmission gear 204c to rotate. Because the transmission gear 204c meshes with the rack 205b, the rotation of the roller 204b drives the rack. When rack 205b moves downward, the first moving rod 205c, which is hinged on both sides of rack 205b, moves downward. Since the other end of the first moving rod 205c is hinged to the clamping rod 205d, when the first moving rod 205c moves downward, the bottom of the clamping rod 205d separates to the left and right. At this time, the upper end of the clamping rod 205d moves inward from the left and right sides, clamping the terminal block through the clamping plate 205f. At the same time, because the fixed frame 202a moves forward, it drives the terminal block to connect to the interface of the electrical component.
