Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fuel dispenser, in particular to a fuel dispenser shell mounting structure. BACKGROUND

[0002] The shell of the fuel dispenser is an important component of the overall structure of the fuel dispenser, which not only provides protection for various internal precision components, but also affects the appearance and overall stability of the fuel dispenser.

[0003] In order to realize the fixed installation of the fuel dispenser shell at the fuel dispenser framework, a through hole is usually provided at the corresponding mounting position of the fuel dispenser shell and the fuel dispenser framework, and the shell is installed through bolts. In this installation process, at least two operators are required to cooperate to realize the assembly of the shell; one operator holds the shell plate and aligns the bolt hole at the shell with the bolt hole at the fuel dispenser framework, and the other operator holds the tool to tighten the bolt.

[0004] However, in the long-term practice of the inventors, it is found that since the alignment of the shell bolt hole and the bolt hole at the framework is by one of the operators holding the alignment, and the shell plate has a certain weight, it is difficult to accurately align and maintain in actual operation; and when tightening the bolt, tools such as wrench, screwdriver, and electric drill need to be prepared in advance, and if the tools are not complete or there are no tools, the installation cannot be performed; in addition, the exposed bolt on the shell surface affects the appearance of the fuel dispenser, and is prone to rusting and loosening; and the fuel dispenser generates high-frequency vibration when working, which greatly increases the risk of bolt loosening, and when the bolt loosens, the shell plate as a whole is prone to falling, which poses a safety risk. In order to hide the bolt under the fuel dispenser shell for the appearance and safety of the fuel dispenser, the tightening operation of the bolt needs to be performed inside the fuel dispenser, which is limited by the internal space of the fuel dispenser, and it is difficult to accurately align the tool with the bolt and screw it into place, which reduces the installation efficiency and reliability.

[0028] In order to better understand the technical solutions of the present application, the above technical solutions will be described in detail below in combination with the drawings in the specification and specific embodiments.

[0029] The existing fuel dispenser shell requires at least two installers to cooperate with each other when assembled, and the installation operation is relatively complex, resulting in low installation efficiency. Therefore, the present example discloses a fuel dispenser shell installation structure, which can realize quick installation and firm fixation of the fuel dispenser shell, and the surface of the fuel dispenser shell is screw-free, ensuring the appearance of the fuel dispenser shell.

[0030] Referring to Figure 1 The fuel dispenser is provided with a fuel dispenser framework plate 2 as a web plate of the fuel dispenser, and the fuel dispenser shell 1 is correspondingly installed and fixed at the fuel dispenser framework plate 2. In order to avoid the installation of screws on the surface of the shell, which affects the appearance of the fuel dispenser and the problem of rusting and loosening of exposed screws, an installation plate 3 is provided at the fuel dispenser framework plate 2 in the present embodiment to assist the installation and fixation of the fuel dispenser shell 1. Referring to Figure 2 In the present example, the installation plate 3 is fixed to the outer surface of the fuel dispenser framework plate 2 along the axial direction of the shell, i.e. the vertical direction. The cross section of the installation plate 3 is L-shaped. After one plate wall of the L-shaped installation plate is attached to and fixedly connected with the fuel dispenser framework plate 2, the other plate wall of the L-shaped installation plate is perpendicular to the fuel dispenser framework plate. In the present example, the installation plate 3 and the fuel dispenser framework plate 2 are connected by welding; in other embodiments, a plurality of bolt holes are respectively formed in the installation plate 3 and the fuel dispenser framework plate 2, and the two are connected and fixed by bolts inserted into the bolt holes.

[0031] In order to realize screw-free installation of the fuel dispenser shell 1, referring to Figure 2 A plurality of limiting slot holes 31 are vertically formed in the plate wall of the L-shaped installation plate perpendicular to the fuel dispenser framework plate. Referring to Figure 1 One side of the fuel dispenser shell 1 is provided with an inner-buckled U-shaped bending part 11, referring to Figure 3The end of the bending part is provided with a plurality of hook plates 12 parallel to the surface of the refueling machine shell, i.e., parallel to the refueling machine skeleton plate after installation. The hook plates 12 are inserted into the corresponding limiting slot holes 31 to realize the installation and fixation of one side of the refueling machine shell 1. The bending part 11 is arranged on one side of the refueling machine shell 1. On one hand, the hook plate is hung inside the shell to avoid direct exposure and affect the appearance of the refueling machine. On the other hand, the hook plate 12 can be hung and limited in the direction parallel to the refueling machine skeleton plate through the bending part, and cooperates with the limiting of the tensioning member on the other side of the shell in the direction perpendicular to the refueling machine skeleton plate, which helps to resist the adverse effects of the body vibration, and thus can effectively improve the stability of the shell installation. In addition, the width of the bending part can be adjusted to serve as the shell plate at the corner of the refueling machine, which can solve the problem of difficult installation and fixation of the shell plate at the corner from two perpendicular directions.

[0032] In addition, in the present embodiment, the hook groove of the hook plate 12 at the end of the shell is vertically downward, so as to stably hang the hook plate in the limiting slot hole 31 by using the weight of the refueling machine shell. In the present embodiment, the vertical length of the limiting slot hole 31 at the installation plate is greater than the vertical length of the hook plate 12, so that the hook plate 12 can be quickly inserted into the limiting slot hole 31, and the alignment difficulty of the hook plate and the limiting slot hole during hanging of the shell is reduced. In addition, referring to Figure 3 The hook groove of the hook plate 12 includes a reduced diameter part 121 and a limiting part 122. The reduced diameter part 121 can realize a guiding effect. After the hook plate 12 is inserted into the limiting slot hole 31, the hook plate 12 of the refueling machine shell automatically falls under the action of the weight of the shell under the guidance of the reduced diameter part 121, and then the hook plate 12 is correspondingly clamped at the bottom position of the limiting slot hole 31. In order to avoid the shell from shaking under the action of external force after the hook plate is correspondingly inserted into the limiting slot hole 31, the width of the limiting slot hole 31 is matched with the thickness of the hook plate 12 in the present embodiment. Considering that the contact between the reduced diameter part 12 and the installation plate is a line contact, it is impossible to realize good limiting of the shell. Therefore, the limiting part 122 is arranged to limit the hook plate 12 and the shell falling into the limiting slot hole. The width of the limiting part is matched with the thickness of the installation plate, so that after the hook plate 12 falls into the limiting slot hole, the limiting part realizes limiting in the direction parallel to the refueling machine skeleton plate, and the two slot walls of the limiting slot hole realize limiting in the direction perpendicular to the refueling machine skeleton plate, so as to ensure the stable fixation of the hook plate side of the refueling machine shell.

[0033] In order to realize the fixation of the other side of the refueling machine shell, and considering that the direct use of bolts to connect the shell on the other side of the refueling machine with the refueling machine skeleton plate is difficult due to the limitation of the operable space inside the refueling machine, the bolt connection is difficult. Therefore, referring to Figure 4, the other side of the fuel dispenser shell is pre-assembled with a tensioning member 4 before the shell is installed on the fuel dispenser frame, the tensioning member 4 provides a pulling and pressing force in a direction perpendicular to the fuel dispenser frame plate, thereby achieving the relative fixed connection between the fuel dispenser shell 1 and the fuel dispenser frame plate 2.

[0034] The fuel dispenser shell is provided with a plurality of mounting holes on the side where the tensioning member is assembled, each mounting hole is provided on the end face of the fuel dispenser shell for abutting contact with the fuel dispenser frame plate. For details, see Figure 5 , the tensioning member 4 includes a hollow guide sleeve 41 fixed to the inner edge surface of the U-shaped bending part of the fuel dispenser shell 1, the hollow guide sleeve 41 is arranged coaxially with the corresponding mounting hole and perpendicular to the fuel dispenser frame plate. In this embodiment, the hollow guide sleeve 41 is welded and fixed to the inner edge surface of the fuel dispenser shell. A guide rod 42 with a limiting seat 421 at one end and a pressing rod 43 hingedly connected at the other end is slidably arranged in the hollow guide sleeve 41. In addition, a spring 44 is arranged around the guide rod in the cavity of the hollow guide sleeve 41. In this embodiment, the diameter of the hollow guide sleeve 41 is greater than the diameter of the mounting hole, so that one end of the spring 44 can abut against the fuel dispenser shell, and the other end of the spring can abut against the limiting seat 421, so that when the guide rod 42 moves in the axial direction, the spring is compressed by the limiting seat 421, so that the guide rod is subjected to a counterforce in the direction of movement.

[0035] In addition, the other end of the guide rod 42 is hingedly connected with the pressing rod 43, which includes a handle 431 and a hinge joint 432, see Figure 6 , the hinge joint 432 is provided with a gradually expanding arc surface 4321 and a limiting surface 4322, wherein the distance between the point on the edge line of the gradually expanding arc surface 4321 and the hinge shaft 433 of the hinge joint gradually increases, as shown in Figure 6 , the distances between the two end lines of the gradually expanding arc surface and the hinge shaft 433 are R1 and R2 respectively, and R1 is less than R2. In addition, the limiting surface 4322 is a plane, and the intersection between the limiting surface and the gradually expanding arc surface is provided with a circular arc chamfer, and the plane where the limiting surface is located does not intersect with the handle 431, that is, there is no interference. Further, see Figure 2The inverse L-shaped slot hole 21 is arranged on the fuel dispenser framework plate 2 and matches the tensioning member 4, which is used to pass through the tensioning member. Thus, the pressing rod 43 of the tensioning member is located at the inner edge surface of the fuel dispenser framework plate, and the gradually expanding arc surface 4321 of the hinged joint 432 is in contact with the fuel dispenser framework plate at the initial moment, so that when the pressing rod 43 is rotated, the distance between the fuel dispenser framework plate and the hinged shaft 433 increases from R1 to R2. That is, the gradually expanding arc surface of the hinged joint 432 is in contact with the fuel dispenser framework plate, so that the guide rod 42 is pulled along the axial direction, thereby the spring 44 is pulled tightly by the elastic force, the fuel dispenser shell is pulled tightly, and the reliable connection between the fuel dispenser shell and the fuel dispenser framework plate can be maintained even if there is external vibration. After the pressing rod 43 is pressed to the limit surface 4322 of the hinged joint which is in contact with the fuel dispenser framework plate, the large contact area between the limit surface and the fuel dispenser framework plate is used to avoid the problem that the pulling fixation is invalid due to the turning of the pressing rod 43 caused by external vibration, and the pressing effect is ensured.

[0036] In the embodiment, in order to facilitate the assembly of the guide rod 42, referring to Figure 5 , the guide rod 42 includes an outer threaded rod 422 and an inner threaded tube 423 which are coaxial and threadedly connected, and the limit seat 421 is arranged at one end of the outer threaded rod 422. Thus, when the tensioning member is assembled before the fuel dispenser shell is installed, the outer threaded rod 422 is only needed to be filled into the hollow guide sleeve 41, and the inner threaded tube 423 is inserted into the installation hole to be threadedly connected with the outer threaded rod 422. However, in order to avoid the problem that the outer threaded rod 422 rotates in the hollow guide sleeve when the two are threadedly connected, and the thread connection between the two cannot be screwed in place, in the embodiment, the cavity section of the hollow guide sleeve 41 is hexagonal, the outer edge contour of the limit seat 421 matches the cavity section of the hollow guide sleeve 42, and the diameter of the inscribed circle of the limit seat 421 is greater than that of the corresponding installation hole of the shell, so as to ensure the installation of the spring. Thus, on the one hand, the outer threaded rod with the limit seat at one end can be directly selected as a bolt with a corresponding specification size, and on the other hand, the polygonal cavity matches the polygonal limit seat, so that the outer threaded rod can only move along the axial direction of the hollow guide sleeve, avoiding the problem that the outer threaded rod is easy to rotate when the inner threaded tube is installed.

[0037] After the tensioning member is assembled, although one end of the guide rod 42 is hinged with the pressing rod 43 to prevent the guide rod from falling off the hollow guide sleeve, since the guide rod 42 has a certain length, the guide rod is easy to shake along the axial direction when the shell is not installed, and it cannot be ensured that the hinged joint of each pressing rod 42 can pass through the fuel dispenser framework plate and press and pull on the inner side of the fuel dispenser framework plate when the shell is installed. Therefore, referring to Figure 7, and the corresponding position of the fuel dispenser shell is provided with an annular groove for accommodating the limiting ring, so that after the threaded part of the outer threaded rod 422 is completely screwed into the inner threaded tube 423, the limiting ring 4231 is completely inserted into the annular groove, so that the outer side surface of the limiting ring 4231 is in the same plane as the fuel dispenser shell, thereby avoiding the problem that the limiting ring 4231 protrudes from the fuel dispenser shell, causing a gap between the fuel dispenser shell and the fuel dispenser skeleton plate after being fastened. Thus, by setting the limiting ring, the guide rod 42 will not shake when the tensioning member is assembled and not subjected to external force tensioning and pressing, thereby eliminating the problem that when the fuel dispenser shell is installed, the tensioning member needs to pull the shaking guide rod when passing through the inverted L-shaped slot hole, so that the pressing rod hinge part is in contact with the fuel dispenser skeleton plate.

[0038] In the initial moment after the tensioning member is assembled, the axial direction of the pressing rod 43 is coaxial with the guide rod 42, thereby facilitating the pressing rod 43 to pass through the inverted L-shaped slot hole at the fuel dispenser skeleton plate. In this embodiment, the inverted L-shaped slot hole 21 includes a horizontal part and a vertical part, wherein the horizontal part is used to pass the pressing rod with larger profile size, so the height of the horizontal part is not less than the maximum thickness of the pressing rod 43, and to facilitate the pressing rod to pass through, the height of the horizontal part can be at least twice the maximum thickness of the pressing rod, so that when the pressing rod is not completely coaxial with the guide rod at the initial moment, it still does not affect the pressing rod to quickly and effectively pass through the inverted L-shaped slot hole. Considering that the fuel dispenser shell hook plate needs to be horizontally pushed when installed, the length of the inverted L-shaped slot hole in this example is not less than the width of the hook plate. In addition, in this embodiment, the hinge position of the pressing rod 42 at the end of the guide rod 42 satisfies that when the axial line of the pressing rod 43 is coaxial with the guide rod 42, the distance from the shortest distance point of the hinge axis to the limiting ring 4231 of the inner threaded tube is matched with the thickness of the fuel dispenser skeleton plate. In this example, the width of the vertical part of the inverted L-shaped slot hole is matched with the outer diameter of the guide rod 42, thereby when the fuel dispenser shell is installed, one side of the hook plate is inserted into the limiting slot hole of the installation plate, and the pressing rod is passed through the inverted L-shaped slot hole at the same time. When the hook plate freely falls in the limiting slot hole, the guide rod of the tensioning member falls into the bottom of the vertical part of the inverted L-shaped slot hole, and then the pressing rod 43 is turned to be pulled and pressed, thereby realizing the relative fixation between the fuel dispenser shell and the fuel dispenser skeleton plate.

[0039] In other embodiments, in order to ensure that the guide rod can smoothly fall into the vertical part of the inverted L-shaped slot hole, a chamfer is provided at the inner corner of the horizontal part and the vertical part in this example, thereby playing a guiding role for the guide rod. In addition, in this embodiment, when the handle is parallel to the guide rod, the gradually expanding arc surface is in contact with the fuel dispenser skeleton plate and the deformation amount of the spring is zero; when the handle is perpendicular to the guide rod, the gradually expanding arc surface is in contact with the fuel dispenser skeleton plate and the deformation amount of the spring is greater than zero, thereby ensuring that the fuel dispenser shell is tightly attached to the fuel dispenser skeleton plate through the elastic force of the spring, avoiding shaking caused by external force vibration and the like.

[0040] While several embodiments of the application have been described, it is contemplated that other modifications and alterations will occur to those skilled in the art upon reading the preceding description. It is intended to include all such modifications and alterations insofar as they come within the scope of the appended claims and their equivalents.

[0041] It will be readily apparent to those skilled in the art in light of the present disclosure that various changes and modifications can be made thereto without departing from the spirit and scope of the application. It is therefore intended that such changes and modifications be included within the scope of the application.
