Description

[0001] The present invention relates to the technical field of flow measurement, in particular to an ultrasonic flow measuring device.

[0002] Ultrasonic flowmeters are widely used in industries such as the process industry and medicine. Conventional ultrasonic flowmeters typically comprise a housing and an attached upper housing. Typically, one end of the upper housing is pivotally connected to the housing via a bolt or similar structure. A pressure lock is also mounted on the housing, while the end of the upper housing opposite the bolt has a coupling slide or similar structure that mates with the pressure lock, allowing the end of the upper housing opposite the bolt to be connected to the housing via the pressure lock.

[0003] In conventional ultrasonic flowmeters, the pressure release is typically located on the side of the housing, which means that the release can be accidentally activated during use. This can lead to the accidental opening of the upper housing and thus compromise the proper performance of the measurement.

[0004] To solve this problem, an ultrasonic flowmeter having the features of the independent claim is proposed. Dependent claims relate to variants thereof.

[0005] To solve the problem of accidental opening of the upper housing in conventional ultrasonic flowmeters, the present invention provides an ultrasonic flowmeter that uses a matching sliding-rotating structure and a plug-in connection to create a horizontally concealed connection between the upper housing and the housing. This improves the connection stability between the upper housing and the housing and solves the problem of accidental opening due to contact.

[0006] The technical solution used to solve the technical problem in the present invention includes: An ultrasonic flow measuring device comprising a housing and an upper shell connected to the housing.

[0007] The housing has an oval hole at its first end and a locking groove at its second end.

[0008] The oval hole and the locking groove are arranged in a horizontal direction.

[0009] The first end of the upper shell has a bolt that fits into the oval hole, while the second end has a clutch slide that fits into the locking groove.

[0010] Optionally, two side plates are arranged on two opposite sides of the housing; the number of oval holes is two, with each of the two oval holes positioned on one of the side plates.

[0011] Optionally, each side plate has the same height as the thickness of the top shell.

[0012] Optionally, the device includes a return spring component connected to the bolt.

[0013] Optionally, positioning holes are arranged in the side plates that communicate with the oval holes; the return spring component is positioned in the positioning holes.

[0014] Optionally, a panel is arranged at the first end of the housing; the two ends of the panel are each connected to the two side panels; the panel has the same height as the side panels.

[0015] Optionally, a connecting plate connected vertically to the upper shell is arranged at the second end of the upper shell; the coupling slide is mounted vertically on the connecting plate.

[0016] Optionally, a groove matching the connecting plate is arranged at the second end of the housing; the locking groove is positioned within this groove.

[0017] The advantageous effects of the present invention are: The ultrasonic flowmeter of the present invention achieves a horizontally concealed connection between the upper shell and the housing through the matching sliding-rotating structure and the plug-in connection. This results in a simple design and improved connection stability between the upper shell and the housing. Since the upper shell must first be moved horizontally to release the coupling slide from the locking groove before it can be opened, accidental opening due to unintentional contact during use is prevented. This increases the reliability of the connection between the upper shell and the housing.

[0020] The invention will now be explained in further detail. The following embodiments are exemplary and serve to explain the invention, but should not be construed as limiting.

[0021] When describing the present invention, it should be noted that the terms "first" and "second" are used solely to simplify the description and should not be understood as indicating or suggesting the relative importance or implying the number of the specified technical features. Therefore, a feature designated "first" or "second" may explicitly or implicitly include one or more of these features. In the description of the invention, "several" means two or more, unless expressly defined otherwise.

[0022] In the present invention, unless expressly stated and defined otherwise, a first feature "above" or "below" a second feature includes both direct contact of the first and second features, as well as contact via additional features between them (without direct contact). Furthermore, the term "above," "up," or "on" for a first feature with respect to a second feature includes both the direct upper (orthogonal) position and the slanted upper position, or merely that the horizontal height of the first feature is higher than that of the second feature. Similarly, the term "below," "below," or "under" for a first feature with respect to a second feature includes both the direct lower (orthogonal) position and the slanted lower position, or merely that the horizontal height of the first feature is lower than that of the second feature.

[0023] In order to make the above objects, features and advantages of the present invention clearer and more understandable, the concrete embodiments of the invention are described in detail below with reference to the attached figures.

[0024] In conventional ultrasonic flowmeters, the pressure seal connecting the upper shell to the housing is typically located on the side of the housing. To open the upper shell, it is sufficient to apply external pressure to the pressure seal in the direction of the housing. Therefore, accidental contact with the pressure seal during use—when the pressure seal experiences a force toward the housing—can cause the upper shell to be accidentally opened.

[0025] To solve the problem of accidental opening of the upper shell by touch, the present invention provides an ultrasonic flow measuring device as in Fig. 1 to 4.

[0026] The device comprises a housing 1 and an upper shell 2 connected to the housing 1. The specific structure within the housing 1 can be traced back to the corresponding prior art; the present invention is not limited to the specific structure within the housing 1. To establish the connection between the housing 1 and the upper shell 2, it is preferred according to the invention that an oval bore 11 is arranged at one end of the housing 1 (hereinafter referred to as the first end), while a locking groove 12 is provided at the opposite end (the second end of the housing 1). The oval bore 11 and the locking groove 12 are arranged in a horizontal direction. Accordingly, a bolt 21 matching the oval bore 11 is arranged at one end of the upper shell 2 (the first end of the upper shell 2). The bolt 21 is preferably firmly connected to the upper shell 2.The mating of the bolt 21 and the oval bore 11 enables a sliding, rotating connection between the upper shell 2 and the housing 1. A coupling slide 22, which fits into the locking groove 12, is attached to the opposite end of the upper shell 2 (the second end) to the first end of the upper shell 2, so that the hidden connection between the upper shell 2 and the housing 1 is established by inserting the coupling slide 22 into the locking groove 12.

[0027] When using the ultrasonic flowmeter, the following steps must be performed to open the upper shell 2: The upper shell 2 is stopped and a force is simultaneously exerted in the direction of the coupling slide 22. This causes the bolt 21 to move within the oval bore 11, so that the upper shell 2 slides to the side of the coupling slide 22. As the upper shell 2 moves, the coupling slide 22 slides out of the locking groove 12. The upper shell 2 is then lifted upward, with the bolt 21 rotating in the oval bore 11 to complete the opening process of the upper shell 2. Conversely, the upper shell 2 is closed as follows: The upper shell 2 is placed on the housing 1. The upper shell 2 is then moved to the side of the bolt 21 so that the coupling slide 22 is inserted into the locking groove 12 and the connection between the upper shell 2 and the housing 1 is locked.

[0028] The ultrasonic flowmeter of the present invention enables a horizontally hidden connection between the upper shell 2 and the housing 1 thanks to the matching sliding-rotating structure and the plug-in connection. This is characterized by a simple construction and improved connection stability between the upper shell 2 and the housing 1. Since the upper shell 2 must first be moved horizontally to release the coupling slide 22 from the locking groove 12 before the upper shell 2 can be opened, accidental opening of the upper shell 2 due to unintentional contact during use is effectively prevented. This increases the reliability of the connection between the upper shell 2 and the housing 1.

[0029] Specifically, according to the invention, it is preferred that two opposing side plates 13 are arranged on both sides of the housing 1, between which two side plates 13 form a space for receiving the upper shell 2. The number of oval holes 11 is two, with each of the two holes 11 being positioned on one of the side plates 13.

[0030] The arrangement of the two side plates 13, by which the housing 1 is connected to the upper shell 2, contributes to further simplifying the structure.

[0031] Furthermore, it is preferred that the height of the side plates 13 corresponds to the thickness of the upper shell 2. As a result, the upper surfaces of the upper shell 2 and the side plates 13 are aligned after the upper shell 2 is closed onto the housing 1, resulting in a slimmer and more aesthetically uniform appearance of the ultrasonic flowmeter.

[0032] In order to further reduce the difficulty of closing the upper shell 2, the invention preferably comprises a return spring component 3 connected to the bolt 21.

[0033] Specifically, as in Fig. As shown in Figure 5, positioning holes (not shown) are provided in the side plates 13, which communicate with the oval holes 11. The return spring component 3 is arranged in these positioning holes, so that the return spring 3 bears against the bolt 21 in the oval hole 11 via the positioning hole. The return spring component 3 can be a simple spring device or comprise any standard components suitable for returning the bolt 21.

[0034] During the closing process of the upper shell 2, after it has been applied to the housing 1 as described above, the upper shell 2 is pulled toward the bolt 21 by the spring force of the return spring 3. This simultaneously inserts the coupling slide 22 into the locking groove 12, which reduces the difficulty of closing. At the same time, the provision of the return spring 3 increases safety, since a horizontal force must be applied when opening the upper shell 2 to overcome the spring force of the return spring 3. This minimizes the risk of accidental opening of the upper shell 2 due to incorrect operation and increases the reliability of the structure.

[0035] To further improve aesthetics, it is preferred according to the invention that a baffle 14 is arranged at the first end of the housing 1. Both ends of the baffle 14 are connected to the two side plates 13, and the baffle 14 has the same height as the side plates 13. Thus, the baffle 14 and the side plates 13 together form an installation space suitable for accommodating the upper shell 2. After the upper shell 2 is closed onto the housing 1, a flat upper surface of the ultrasonic flowmeter is created, resulting in a slimmer and more aesthetically uniform appearance.

[0036] To establish the plug-in connection between the upper shell 2 and the housing 1, it is preferred according to the invention that a connecting plate 23 is arranged at the second end of the upper shell 2 and is connected vertically thereto. The coupling slide 22 is mounted vertically on the connecting plate 23 so that the coupling slide 22 runs parallel to the extension direction of the upper shell 2. This enables a horizontal plug-in connection between the upper shell 2 and the housing 1.

[0037] Furthermore, according to the invention, it is preferred that a groove 15 matching the connecting plate 23 is formed at the second end of the housing 1. The locking groove 12 is located within this groove 15. As a result, the connecting plate 23 lies in the groove 15 after the upper shell 2 and housing 1 are connected, resulting in a more uniform and aesthetically improved appearance of the ultrasonic flow measuring device.
