Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] In the present utility model, unless otherwise clearly stipulated and limited, a first feature being "above" or "below" the first feature may include that the first feature is in direct contact with the second feature, or may include that the first feature and the second feature are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the existing ultrasonic flow measurement device, since the push buckle connecting the upper cover and the shell is usually arranged on the side of the shell, when the upper cover needs to be opened, an external force is applied to the push buckle in the direction toward the shell; therefore, during use, if the push buckle is accidentally touched and the push buckle is subjected to an external force directed to one side of the shell, the upper cover may be opened.

[0031] In order to solve the problem that the upper cover is easily opened due to accidental touch, the utility model provides an ultrasonic flow measurement device, see Figure 1-Figure 4As shown, the ultrasonic flow measurement device includes a shell 1 and an upper cover 2 connected to the shell 1; the specific structure in the shell 1 can refer to the corresponding prior art, and the present invention does not limit the specific structure in the shell 1; in order to realize the connection between the shell 1 and the upper cover 2, the present invention preferably has one end of the shell 1, which is recorded as the first end of the shell 1 for the convenience of description, and is provided with a waist-shaped hole 11, and the other end opposite to the first end is recorded as the second end of the shell 1, and is provided with a slot 12; the waist-shaped hole 11 and the slot 12 are arranged along the horizontal Direction distribution; accordingly, one end of the upper cover 2, denoted as the first end of the upper cover 2, is provided with a pin shaft 21 adapted to the waist-shaped hole 11, and the pin shaft 21 is preferably fixedly connected to the upper cover 2, so that the pin shaft 21 cooperates with the waist-shaped hole 11 to achieve a sliding and rotating connection between the upper cover 2 and the shell 1; the other end opposite to the first end of the upper cover 2, denoted as the second end of the upper cover 2, is provided with a card plate 22 adapted to the card slot 12, so that the upper cover 2 and the shell 1 can be plugged in by inserting the card plate 22 into the card slot 12.

[0032] During the use of the ultrasonic flow measurement device, when the upper cover 2 needs to be opened, first press the upper cover 2, and at the same time apply a force pointing to the direction of the card plate 22, the pin shaft 21 moves in the waist-shaped hole 11, so that the upper cover 2 moves to the side where the card plate 22 is provided. As the upper cover 2 moves, the card plate 22 escapes from the card slot 12, and then the upper cover 2 is lifted upward, and the pin shaft 21 rotates in the waist-shaped hole 11 to complete the opening operation of the upper cover 2; on the contrary, when the upper cover 2 needs to be buckled, first close the upper cover 2 on the shell 1, and then push the upper cover 2 to move toward the end where the pin shaft 21 is provided, so that the card plate 22 is inserted into the card slot 12, and the connection and locking of the upper cover 2 and the shell 1 are completed.

[0033] The ultrasonic flow measurement device provided by the utility model realizes horizontal plug-in connection between the upper cover 2 and the shell 1 through the sliding and rotating structure and the plug-in structure that cooperate with each other. The structure is simple and the stability of the connection between the upper cover 2 and the shell 1 is improved. Since the ultrasonic flow measurement device needs to push the upper cover 2 in the horizontal direction first so that the card plate 22 is disengaged from the card slot 12, the upper cover 2 can be opened, thereby avoiding the upper cover 2 from being opened due to accidental touch during use, and improving the reliability of the connection between the upper cover 2 and the shell 1.

[0034] Specifically, the utility model preferably has two side panels 13 disposed on both sides of the shell 1 opposite to each other, and a space suitable for placing the upper cover 2 is formed between the two side panels 13; the number of the waist-shaped holes 11 is two, and the two waist-shaped holes 11 are respectively disposed on the two side panels 13.

[0035] By providing two side plates 13 , the housing 1 is connected to the upper cover 2 through the two side plates 13 , which helps to further simplify the structure.

[0036] Furthermore, the utility model preferably has the side panel 13 of the same height as the thickness of the upper cover 2, so that after the upper cover 2 is covered on the housing 1, the upper surface of the upper cover 2 is flush with the upper surfaces of the two side panels 13, thereby making the appearance of the ultrasonic flow measurement device more concise and beautiful.

[0037] In order to further reduce the difficulty of closing the upper cover 2 , the utility model preferably configures the ultrasonic flow measurement device to further include a return spring assembly 3 connected to the pin 21 .

[0038] For details, see Figure 5 As shown, the utility model preferably has a limiting hole (not shown in the figure) in communication with the waist-shaped hole 11 in the side plate 13; the reset spring assembly 3 is arranged in the limiting hole, so that the reset spring 3 abuts against the pin 21 in the waist-shaped hole 11 through the limiting hole; the reset spring assembly 3 can be only a spring structure, or it can be any existing standard part that can realize the reset of the pin 21.

[0039] During the closing process of the upper cover 2, after the upper cover 2 is fitted with the shell 1 according to the process described above, the upper cover 2 is moved in the direction close to the pin shaft 21 under the action of the elastic force of the return spring 3, and the plugging of the card plate 22 and the card slot 12 is realized, thereby reducing the difficulty of closing; at the same time, after the return spring 3 is set, since it is necessary to overcome the elastic force of the return spring 3 in the horizontal direction during the opening process of the upper cover 2, it helps to further reduce the risk of the upper cover 2 being opened by mistake and improve the reliability of the structure.

[0040] In order to further improve the aesthetics, the utility model preferably provides a baffle 14 at the first end of the shell 1; the two ends of the baffle 14 are respectively connected to the two side panels 13; the baffle 14 has the same height as the side panels 13, so that the baffle 14 and the two side panels 13 together enclose a mounting cavity adapted to the upper cover 2. After the upper cover 2 is covered on the shell 1, the ultrasonic flow measurement device forms a structure with a flat upper surface, and the appearance is more concise and beautiful.

[0041] In order to realize the plug-in connection between the upper cover 2 and the shell 1, the utility model preferably provides a connecting plate 23 vertically connected to the upper cover 2 at the second end of the upper cover 2; the card plate 22 is vertically connected to the connecting plate 23 so that the distribution direction of the card plate 22 is parallel to the upper cover 2, thereby realizing the plug-in connection between the upper plate 2 and the shell 1 in the horizontal direction.

[0042] Furthermore, the utility model preferably provides a groove 15 compatible with the connecting plate 23 at the second end of the shell 1; the card slot 12 is arranged in the groove 15, so that after the upper cover 2 is connected to the shell 1, the connecting plate 23 is located in the groove 15, so that the ultrasonic flow measurement device forms a more unified and beautiful appearance.

[0043] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description.
