Description

Technical Field

[0001] This utility model belongs to the field of cylinder cleaning technology, specifically relating to a control switch protection structure and a Coriolis mass flow meter. Background Technology

[0002] The Coriolis mass flow meter is a high-precision flow measurement device based on the Coriolis force principle, widely used in various industries such as chemical, petroleum, food, and pharmaceutical. Its core working principle is to directly measure the mass flow rate by measuring the Coriolis force generated by the fluid in a vibrating pipe, unaffected by factors such as fluid density, viscosity, temperature, and pressure.

[0003] However, when using flow meters now, because their display screen and control switch are exposed, they are not only easily bumped and knocked over over time, but also easily accumulate dust on the surface of the display screen. In some humid environments, water droplets can even stick to the surface of the display screen. When water droplets enter the flow meter, they can damage the internal components of the flow meter, which will greatly shorten the service life of the flow meter.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a control switch protection structure and a Coriolis mass flow meter.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a control switch protection structure and a Coriolis mass flow meter, which can solve the problem of the lack of a protection structure for the control switch of existing flow meters.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides a control switch protection structure, including: a main housing and a mounting mechanism;

[0008] A cover plate groove is chiseled on one side of the main housing, and a cover plate is rotatably installed in the cover plate groove. A first groove is chiseled at the bottom of the main housing, and a locking tongue is fixed in the first groove. A pair of sliding rods are slidably installed at the bottom of the cover plate, and a locking rod is installed outside the cover plate between the pair of sliding rods. The locking rod is engaged with the locking tongue.

[0009] The mounting mechanism is mounted on the main housing. The mounting mechanism includes multiple grippers, which are evenly fixed to the side of the main housing away from the cover plate groove. Each gripper includes a connecting arm, a pressing part, and an inwardly recessed locking part. An embedding groove is chiseled on the side of the main housing away from the cover plate groove. The radius of the inner arc of the locking part is slightly smaller than the radius of the embedding groove. Locking sleeves are slidably disposed on the outside of the multiple grippers. Limiting heads are fixed at the ends of the pressing parts away from the connecting arms. Multiple limiting grooves corresponding to the limiting heads are chiseled on the locking sleeves. First slots are chiseled on the pressing parts. Multiple first locking blocks that are adapted to the first slots are fixed on the inner wall of the locking sleeves.

[0010] In one or more embodiments of this utility model, a second groove is chiseled at the upper end of the main housing, a fixed shaft is fixed in the second groove, and a U-shaped bushing is fixed at the upper end of the cover plate. The U-shaped bushing is rotatably connected to the fixed shaft, and the rotation between the cover plate and the main housing is realized by rotating the U-shaped bushing on the fixed shaft.

[0011] In one or more embodiments of this utility model, an insert plate is fixed on the inner bottom wall of the U-shaped bushing, and a slot adapted to the insert plate is chiseled on the top of the fixed shaft. When the cover plate is opened 180 degrees from the cover plate slot, the cover plate is turned downwards, so that the fixed shaft moves from one end of the U-shaped bushing to the other end, thereby inserting the insert plate into the slot and fixing the state of the cover plate when it is open.

[0012] In one or more embodiments of this utility model, an observation window is provided on the cover plate, through which the data information on the flow meter display screen can be observed.

[0013] In one or more embodiments of this utility model, a fixing head is fixed at one end of a pair of slide rods inside the cover plate. A first spring is installed on each pair of slide rods between the fixing head and the inner wall of the cover plate. The fixing head is used to prevent the slide rod from sliding off the cover plate. On the other hand, the fixing head is pushed upward by the elastic force of the first spring. The fixing head drives the locking rod to move up and down through the pair of slide rods, so that the locking rod is locked on the locking tongue.

[0014] In one or more embodiments of this utility model, a pull plate is fixed at one end of the pair of slide rods at the bottom of the lock rod. By pressing the pull plate downward, the pull plate drives the pair of slide rods to move downward, and the pair of slide rods drive the lock rod to move downward and move away from the lock tongue. Then the cover plate can be rotated open from the cover plate groove.

[0015] In one or more embodiments of this utility model, an anti-slip layer is fixed on the inner side of the locking part, and the anti-slip layer plays an anti-slip role.

[0016] In one or more embodiments of this utility model, a pair of second locking blocks are slidably disposed on the main housing, and a pair of second locking grooves adapted to the second locking blocks are chiseled at the end of the locking sleeve away from the first locking block. When the locking sleeve is locked on the clamping jaw, it is locked in the second locking groove by the second locking block, thereby preventing the locking sleeve from rotating. At the same time, the second locking block cooperates with the limiting head to prevent the locking sleeve from moving horizontally.

[0017] In one or more embodiments of this utility model, a pair of second locking blocks are fixed with a pair of limiting claws inside the main housing, and a second spring is installed between the pair of second locking blocks and the inner wall of the main housing. The limiting claws prevent the second locking blocks from detaching from the main housing, and the elastic force of the second spring pushes the second locking blocks outward so that they are locked in the second locking slot.

[0018] A Coriolis mass flow meter includes the control switch protection structure described above.

[0019] Compared with the prior art, this utility model effectively protects the flow meter's switching through relevant structural design, thereby effectively improving the flow meter's service life. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0034] like Figures 1 to 10 As shown, a control switch protection structure in one embodiment of the present invention includes: a main housing 1 and a mounting mechanism 2.

[0035] like Figures 1 to 5 As shown, a cover plate groove 101 is cut out on one side of the main housing 1, and a cover plate 102 is rotatably disposed in the cover plate groove 101. The cover plate 102 covers the cover plate groove 101, thereby providing protection for the control switch panel of the flow meter.

[0036] Secondly, a first groove 103 is chiseled at the bottom of the main housing 1, and a locking tongue 104 is fixed in the first groove 103. A pair of sliding rods 105 are slidably arranged at the bottom of the cover plate 102. A locking rod 106 is installed between the pair of sliding rods 105 outside the cover plate 102. The locking rod 106 is locked on the locking tongue 104. By locking the locking rod 106 on the locking tongue 104, the cover plate 102 is locked when it is closed in the cover plate groove 101.

[0037] like Figures 3 to 6 As shown, a second groove 111 is cut into the upper end of the main housing 1, and a fixed shaft 112 is fixed in the second groove 111. A U-shaped bushing 113 is fixed to the upper end of the cover plate 102. The U-shaped bushing 113 is rotatably connected to the fixed shaft 112. The rotation between the cover plate 102 and the main housing 1 is achieved by rotating the U-shaped bushing 113 on the fixed shaft 112.

[0038] like Figures 3 to 6 As shown, an insert plate 114 is fixed on the inner bottom wall of the U-shaped bushing 113. A slot 115 adapted to the insert plate 114 is carved on the top of the fixed shaft 112. When the cover plate 102 is opened 180 degrees from the cover plate groove 101, the cover plate 102 is turned downwards, so that the fixed shaft 112 moves from one end of the U-shaped bushing 113 to the other end, thereby inserting the insert plate 114 into the slot 115, thus fixing the state of the cover plate 102 when it is open.

[0039] like Figure 1 and Figure 3 As shown, an observation window 110 is cut into the cover plate 102, through which the data information on the flow meter display screen can be observed.

[0040] like Figure 3 As shown, a pair of slide rods 105 are fixed to a fixing head 108 at one end inside the cover plate 102. A first spring 109 is installed on each of the slide rods 105 between the fixing head 108 and the inner wall of the cover plate 102. The fixing head 108 is used to prevent the slide rods 105 from slipping off the cover plate 102. On the other hand, the fixing head 108 is pushed upward by the elastic force of the first spring 109. The fixing head 108 drives the locking rod 106 to move up and down through the pair of slide rods 105, so that the locking rod 106 is locked on the locking tongue 104.

[0041] like Figure 3 As shown, a pair of slide rods 105 are fixed to a pull plate 107 at one end of the bottom of the locking rod 106. By pressing the pull plate 107 downward, the pull plate 107 drives the pair of slide rods 105 to move downward, and the pair of slide rods 105 drive the locking rod 106 to move downward and move away from the locking tongue 104. Then the cover plate 102 can be rotated open from the cover plate groove 101.

[0042] like Figures 2 to 10As shown, the mounting mechanism 2 is mounted on the main housing 1. The mounting mechanism 2 includes multiple grippers 201, which are evenly fixed on the side of the main housing 1 away from the cover plate groove 101. Each gripper 201 includes a connecting arm 204, a pressing part 205, and an inwardly recessed locking part 206. When this device is installed on the flow meter, when the gripper 201 is clamped on the flow meter, the locking part 206 will clamp on the flow meter, and one end of the pressing part 205 will be raised outward. Then, after the locking sleeve 202 is pushed towards the gripper 201, the locking sleeve 202 will press the pressing part 205 inward. The pressing part 205 drives the locking part 206 to clamp the flow meter, thereby completing the fixation on the flow meter.

[0043] In addition, an embedding groove 203 is chiseled on the side of the main housing 1 away from the cover plate groove 101. The radius of the inner arc of the locking part 206 is slightly smaller than the radius of the embedding groove 203. The flow meter control switch head is locked in the embedding groove 203. Because the radius of the inner arc of the locking part 206 is slightly smaller than the radius of the embedding groove 203, when this device is installed on the flow meter, the flow meter body will push the clamp 201 outward, thereby causing the outer end of the pressing part 205 to tilt outward.

[0044] Secondly, locking sleeves 202 are slidably provided on the outside of multiple grippers 201, and limiting heads 208 are fixed at the ends of multiple pressing parts 205 away from the connecting arm 204. Multiple limiting grooves 211 corresponding to the limiting heads 208 are carved on the locking sleeves 202. The limiting heads 208 are used to limit the locking sleeves 202 to prevent the locking sleeves 202 from detaching from the grippers 201. When the locking sleeves 202 are locked on the grippers 201 and rotate, the limiting heads 208 slide in the limiting grooves 211.

[0045] Finally, each of the multiple clamping parts 205 has a first slot 209. The inner wall of the locking sleeve 202 is fixed with multiple first locking blocks 210 that are adapted to the first slot 209. After the locking sleeve 202 is pushed onto the gripper 201, the locking sleeve 202 is rotated so that the first locking blocks 210 are locked onto the first slot 209, thereby preventing the locking sleeve 202 from moving horizontally. At the same time, when the locking sleeve 202 is removed from the gripper 201, the first locking blocks 210 are also used to limit the locking sleeve 202 and prevent the locking sleeve 202 from sliding off the main housing 1.

[0046] like Figure 2 and Figure 7 As shown, an anti-slip layer 207 is fixed on the inner side of the locking part 206, and the anti-slip layer 207 plays an anti-slip role.

[0047] like Figures 7 to 8As shown, a pair of second locking blocks 213 are slidably disposed on the main housing 1. The locking sleeve 202 has a pair of second locking grooves 212 adapted to the second locking blocks 213 at one end away from the first locking block 210. When the locking sleeve 202 is locked on the gripper 201, it is locked in the second locking grooves 212 by the second locking blocks 213, thereby preventing the locking sleeve 202 from rotating. At the same time, the second locking blocks 213 cooperate with the limiting head 208 to prevent the locking sleeve 202 from moving horizontally.

[0048] like Figures 7 to 8 As shown, a pair of second locking blocks 213 are provided inside the main housing 1, each with a pair of limiting claws 214 fixed thereon. A second spring 215 is installed between the pair of second locking blocks 213 and the inner wall of the main housing 1. The limiting claws 214 prevent the second locking blocks 213 from detaching from the main housing 1. The elastic force of the second spring 215 pushes the second locking blocks 213 outward, so that they are locked in the second locking slot 212.

[0049] An embodiment of this utility model also provides a Coriolis mass flow meter, which includes the control switch protection structure described above.

[0050] Working principle: Before installing this device onto the flow meter, the locking sleeve 202 is sleeved on the clamp 201. First, the locking sleeve 202 needs to be removed from the clamp 201. First, press the pair of second locking blocks 213 inward, then rotate the locking sleeve 202. The locking sleeve 202 drives the first locking block 210 to move out of the first locking groove 209. Then, move the locking sleeve 202 towards the cover plate 102 and remove the locking sleeve 202 from the clamp 201.

[0051] Then, align the multiple grippers 201 with the head of the flowmeter control panel and push the device into the flowmeter, causing the grippers 201 to lock onto the flowmeter and the head of the flowmeter to lock into the embedding groove 203. When the device is pushed into the flowmeter, the locking part 206 contacts the outer edge of the flowmeter and slightly opens the grippers 201 outward, causing one end of the pressing part 205 to tilt outward. Then, push the locking sleeve 202 onto the grippers 201. When the locking sleeve 202 is pushed onto the grippers 201, it presses the pressing part 205 inward, and the pressing part 205 drives the locking part 206. After clamping the flow meter and pushing the limiting groove 211 into the limiting head 208, rotate the locking sleeve 202 to insert the first locking block 210 into the first locking groove 209, thereby locking the locking sleeve 202 horizontally and preventing it from moving horizontally. At the same time, when the first locking block 210 is inserted into the first locking groove 209, the elastic force of the second spring 215 pushes the second locking block 213 outward, so that the second locking block 213 is locked in the second locking groove 212, thereby preventing the locking sleeve 202 from rotating. This completes the installation and fixing of the device.

[0052] When it is necessary to open the cover plate 102 from the main housing 1, the pull plate 107 drives a pair of slide rods 105 to move downwards. The slide rods 105 drive the locking rod 106 to move away from the locking tongue 104, and finally open the cover plate 102 by 180 degrees. Then, the cover plate 102 is lowered to one end, so that the fixing shaft 112 moves from one end of the U-shaped bushing 113 to the other end, thereby inserting the insert plate 114 into the slot 115, thereby fixing the state of the cover plate 102 when it is open.

[0053] When it is necessary to close the cover plate 102 in the cover plate groove 101, first lift the cover plate 102 upward, then rotate the cover plate 102 downward by 180 degrees. After the locking rod 106 contacts the locking tongue 104, the locking rod 106 drives a pair of sliding rods 105 to move downward. When the locking rod 106 moves to the inside of the locking tongue 104, the elastic force of the first spring 109 pushes the fixing head 108 upward. The fixing head 108 drives the locking rod 106 to move upward through a pair of sliding rods 105, so that the locking rod 106 is locked in the locking tongue 104, thereby completing the closing of the cover plate 102 in the cover plate groove 101.
