DETAILED DESCRIPTION

[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 6 As shown, a stainless steel scraper flowmeter comprises a flowmeter body 1 with an electrical box 2 on the top, a first protective cover 5 and a second protective cover 6 are symmetrically arranged on the top of the flowmeter body 1 with respect to the electrical box 2, an inverted T-shaped slider 4 is arranged at the bottom of the first protective cover 5 and the second protective cover 6, an inverted T-shaped slide groove 3 for limiting the inverted T-shaped slider 4 is symmetrically arranged on the top of the flowmeter body 1 with respect to the electrical box 2, a clamping block 7 is arranged on the second protective cover 6, a clamping slot 8 for inserting the clamping block 7 is arranged on the first protective cover 5, and locking mechanisms for locking the clamping block 7 inserted into the clamping slot 8 are symmetrically arranged on both sides of the inner wall of the clamping slot 8.

[0023] In this embodiment, the inverted T-shaped slide groove 3 is used to guide and limit the inverted T-shaped slider 4, so that the movement of the first protective cover 5 and the second protective cover 6 is guided and limited. When the first protective cover 5 and the second protective cover 6 approach each other, the card block 7 will gradually insert into the interior of the card slot 8, and then the locking mechanism will lock the card block 7 in the interior of the card slot 8, thereby completing the card connection installation of the first protective cover 5 and the second protective cover 6, so that the electrical box 2 is protected. The installation steps of the first protective cover 5 and the second protective cover 6 are simple, which greatly reduces people's workload in actual use. At the same time, there is no situation of loss of parts, which improves the practicability of the device.

[0024] like Figures 3 to 5As shown, the locking mechanism includes a mounting hole 9, a guide hole 10, a guide column 11, an inclined block 12 and a first spring 13. The mounting holes 9 are symmetrically arranged on both sides of the inner wall of the card slot 8, the guide holes 10 are symmetrically arranged on both sides of the first protective cover 5, the guide column 11 is penetrated into the inside of the guide hole 10, the inclined block 12 is arranged at one end of the guide column 11 located in the card slot 8, the first spring 13 is arranged around the outer surface of the guide column 11, and the two ends of the first spring 13 are respectively connected to the mounting hole 9 and the inclined block 12.

[0025] In this embodiment, the inclined surface on the block 7 matches the inclined surface on the inclined block 12. As the block 7 is inserted into the slot 8 and a thrust is applied to the inclined block 12, when the inclined block 12 is subjected to the thrust from the block 7, due to the mutual cooperation between the inclined surface on the inclined block 12 and the block 7, the inclined block 12 will shrink toward the inside of the mounting hole 9 through the mutual cooperation between the guide column 11 and the guide hole 10, until the head of the block 7 passes through the inclined block 12 and reaches the other side of the inclined block 12, the rebound effect of the first spring 13 drives the inclined block 12 to extend out of the mounting hole 9, at which time the inclined block 12 locks and limits the block 7, thereby achieving the purpose of clamping and installing the first protective cover 5 and the second protective cover 6.

[0026] like Figure 6 As shown, a pull ring 18 is provided at one end of the guide column 11 located at the guide hole 10 through a rope.

[0027] In this embodiment, the guide column 11 is moved by pulling the pull ring 18, and the movement of the guide column 11 drives the inclined block 12 to retract into the interior of the mounting hole 9, releasing the locking of the inclined block 12 on the clamping block 7, making it easier for people to disassemble the first protective cover 5 and the second protective cover 6.

[0028] like Figure 3 and Figure 4 As shown, the interior of the card slot 8 is provided with an ejection assembly for ejecting the card block 7 out of the card slot 8, and the ejection assembly includes a mounting groove 14 arranged inside the card slot 8, a second spring 15 is arranged inside the mounting groove 14, and the second spring 15 is provided with a push plate 16 at one end of the card slot 8, and a telescopic column 17 is arranged inside the second spring 15 for preventing the second spring 15 from shaking when it is extended and retracted.

[0029] In this embodiment, when the inclined block 12 is no longer locked by the block 7 through the pull ring 18, the second spring 15 drives the push plate 16 to push the block 7 out of the slot 8. The setting of the telescopic column 17 prevents the second spring 15 from shaking when it is extended and retracted, greatly improving the applicability of the stainless steel scraper flowmeter.

[0030] Working principle: when in use, the inverted T-shaped slide groove 3 is used to guide and limit the inverted T-shaped slider 4, so that the movement of the first protective cover 5 and the second protective cover 6 is guided and limited. When the first protective cover 5 and the second protective cover 6 approach each other, the block 7 will gradually insert into the slot 8, and the inclined surface on the block 7 matches the inclined surface on the inclined block 12. As the block 7 is inserted into the slot 8 and thrust is applied to the inclined block 12, when the inclined block 12 is thrusted by the block 7, due to the mutual cooperation between the inclined block 12 and the inclined surfaces on the block 7, the inclined block 12 will shrink toward the inside of the mounting hole 9 through the mutual cooperation between the guide column 11 and the guide hole 10, until the head of the block 7 passes through the inclined block 12 and reaches the other side of the inclined block 12, the rebound effect of the first spring 13 drives the inclined block 12 to extend out of the mounting hole 9, and at this time the inclined block 12 locks and limits the block 7. The first and second protective covers 5 and 6 are in position, so as to achieve the purpose of clamping and installing the first protective cover 5 and the second protective cover 6, so that the electrical box 2 is protected. The installation steps of the first and second protective covers 5 and 6 are simple, which greatly reduces people's workload in actual use. At the same time, there is no situation of loss of parts, which improves the practicability of the device; by pulling the pull ring 18, the guide column 11 is driven to move, and the movement of the guide column 11 drives the inclined block 12 to retract into the interior of the installation hole 9, thereby releasing the lock of the inclined block 12 on the block 7, making it convenient for people to disassemble the first protective cover 5 and the second protective cover 6; when the inclined block 12 is no longer locked by the pull ring 18, the second spring 15 drives the push plate 16 to push the block 7 out of the slot 8, and the setting of the telescopic column 17 prevents the second spring 15 from shaking when it is extended and retracted, which greatly improves the applicability of the stainless steel scraper flowmeter.
