Description

Technical Field

[0001] This utility model relates to the field of unloading control technology, specifically to a structure for fixing an unloading gun and a chip holder. Background Technology

[0002] The specification drawing of the patent with publication number CN216467522U discloses a liquid discharge gun, the gun head of which includes a tube, a valve body and an ACME connector. One end of the tube is open and the other end of the tube is connected to the valve body. The valve body is provided with an ACME connector at a position away from the tube. Both the valve body and the ACME connector are provided with an external hexagonal structure for easy installation and a part with a circular outer edge of the cross section near the external hexagonal structure.

[0003] Patent CN216286713U discloses an explosion-proof card reader for a liquid unloading gun, which has an identification chip inside. It is used to identify and compare waybill information and determine whether the liquefied petroleum gas storage tank should be filled with liquid, thereby avoiding illegal unloading.

[0004] In the existing technology, in order to avoid the loss of the explosion-proof card reader for the liquid discharge gun, the explosion-proof card reader for the liquid discharge gun is usually fixed directly to the valve body of the liquid discharge gun with fasteners. This requires workers to drill holes in the liquid discharge gun, which will damage the structure of the liquid discharge gun itself. If the hole is too deep, there is a possibility of piercing the liquid discharge gun. Utility Model Content

[0005] The purpose of this invention is to provide a liquid discharge gun and chip holder fixing structure that does not require processing of the original liquid discharge gun and facilitates identification of the chip and the liquid discharge gun fixing.

[0006] To achieve the above objectives, this utility model employs a liquid discharge gun and chip holder fixing structure. The liquid discharge gun includes a valve body and an ACME connector. The valve body is provided with a chip holder, which includes a fixing plate and fixing rings sleeved on both ends of the valve body. One fixing ring contacts the axial surface of the protruding part of the ACME connector. Each end of the fixing plate is fixed with a fixing ring. Each fixing ring includes two opposing semi-annular fixing ring units. One end of the two fixing ring units is connected and fixed by a first fastener, and the other end of the two fixing ring units is fixed together by the fixing plate. The fixing plate includes a plate body and a fixing cover made of transparent material. The plate body is provided with an installation groove for placing the identification chip. The fixing cover is fixed to the plate body and covers the installation groove.

[0007] Two semi-circular retaining rings are held together at the end of the valve body to fix the chip holder to the valve body. The first fastener laterally locks the retaining ring, causing it to contract and hug the valve body, achieving radial fixation. The fixing plate longitudinally connects the two retaining rings to achieve axial positioning. The entire structure only contacts the valve body surface, requiring no drilling, tapping, or welding. Therefore, it does not require processing on the unloading gun and can be directly assembled and fixed on the existing unloading gun.

[0008] The identification chip (the card reader containing the chip) is secured using a mounting slot and a fixing cover. The transparent fixing cover facilitates scanning and confirmation of the identification chip and can be made of acrylic or other materials. The chip holder's position is determined by aligning the fixing ring on one side of the chip holder with the axial surface of the protruding portion (hexagonal structure) of the ACME connector, preventing the chip holder from deviating axially from the valve body.

[0009] Preferably, the end of the plate body is fixed to the retaining ring unit by a second fastener, and the extension direction of the first fastener is perpendicular to the extension direction of the second fastener. The fastening forces in the two directions are independent of each other, and the clamping preload of the retaining ring will not be affected when the plate is disassembled or assembled, ensuring the reliability of the fixation with the valve body.

[0010] Preferably, the two retaining rings do not contact each other, and there is a gap between them. This gap allows the inner diameter of the retaining ring to be elastically adjusted within a certain range, adapting to the valve body casting tolerances and ensuring uniform clamping force.

[0011] Preferably, the two fixing ring units of the fixing ring have a fixing plane formed on the same side wall, and the plate body is in contact with the fixing plane. Surface contact reduces the pressure per unit area, avoids local plastic deformation caused by point contact, and extends the life of the chip bracket.

[0012] Preferably, one of the two fixed end units of the fixed ring has a relief groove that allows for clearance of the head of the first fastener.

[0013] This invention has the advantage that it does not require processing on the unloading gun, and the identification chip can be directly assembled and fixed on the existing unloading gun. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0019] Depend on Figures 1 to 4 As shown, a liquid discharge gun and a chip holder fixing structure are disclosed. This liquid discharge gun is a prior art liquid discharge gun used for filling liquefied petroleum gas storage tanks. The liquid discharge gun includes a valve body 1, a pipe section 2, and an ACME connector 9. The valve body 1 has an external hexagonal structure 11 at its end and a cylindrical section with a circular outer edge. The chip holder includes a fixing plate 3 and two fixing rings 4. Each fixing ring 4 is composed of two fixing ring units 41 forming a ring structure, and the two fixing rings 4 are respectively fitted onto both ends of the valve body 1.

[0020] The fixing plate 3 includes a plate body 6 and a fixing cover 6a. The plate body 6 is a rectangular flat plate. The side of the plate body 6 away from the valve body 1 is provided with an installation groove. The identification chip 7 is placed in the installation groove. The fixing cover 6a, made of transparent material, is connected to the plate body 6 by four third fasteners 6b, covering the installation groove and sealing and protecting the identification chip 7.

[0021] Both ends of the fixing plate 3 are separately fixed to the two fixing ring units 41 of the fixing ring 4 by two second fasteners 8. The two fixing ring units of the fixing ring 4 are connected and fixed by a first fastener 5, the extension direction of the first fastener 5 being perpendicular to the extension direction of the second fastener 8. The end faces of the fixing ring 4 used for fixing to the fixing plate 3 are all fixed planes, and the plate body 6 is attached to these fixed planes and fixed by the second fasteners 8. One of the two fixing ring units 41 of the fixing ring 4 has a clearance groove 42 that accommodates the head of the first fastener 5 and a through hole for the first fastener 5 to pass through. The diameter of the through hole is smaller than the width of the clearance groove 42. The other fixing ring unit 41 of the fixing ring 4 has an internal thread structure that mates with the threaded section of the first fastener 5. In this embodiment, the first fastener 5, the second fastener 8, and the third fastener 6b are all bolts. The inner diameters of the two fixing rings in this embodiment are different, set according to the specific dimensions of both ends of the valve body 1. For ease of use when fitted onto the valve body ends, one of the internal threaded holes of the two fixing rings in this embodiment is a through hole and the other is a blind hole.

[0022] Insert the identification chip 7 into the mounting slot of the board body 6, close the fixing cover 6a and tighten the screws; fasten the fixing ring unit to the outside of the valve body 1 of the liquid discharge gun, so that one fixing ring is in contact with the axial end face of the protruding part (external hexagonal structure 11) of the ACME connector 9, and fix the fixing plate 3 and the fixing ring 4 by the second fastener 8, and then close the two fixing ring units 41 of the fixing ring 3 by the first fastener 5, thereby achieving the tight fixing of the fixing ring 3 and the valve body 1.

[0023] This embodiment has the advantage that it does not require processing on the unloading gun, and the identification chip can be directly assembled and fixed on the original unloading gun.
