Description

Technical Field

[0001] This utility model relates to the technical field of fuel filter elements for fuel dispensers, specifically a fuel filter element for fuel dispensers that is easy to replace. Background Technology

[0002] An easy-to-replace fuel filter for a fuel dispenser is a device that facilitates the replacement and installation of the fuel filter from inside the housing of the fuel dispenser.

[0003] Based on the above, the inventors have discovered that: Currently, there are many fuel filter elements for gas pumps on the market. However, when the internal structure of a typical fuel filter element fails to achieve a good filtration effect, it requires workers to disassemble and replace the filter element along with its housing. This significantly increases the workload for workers and prolongs the maintenance time, thus reducing the practicality of the device. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a fuel filter element for gas pumps that is easy to replace, aiming to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a fuel filter element for a refueling machine that is easy to replace, including a housing, a ring plate fixed at one end of the housing, a cover plate at the other end of the housing, an installation mechanism on the inner wall of the housing, and a reinforcement mechanism at one end of the cover plate.

[0006] The installation mechanism includes:

[0007] The filter element body is disposed on the inner wall of the housing. Two sliders are fixed on the outer wall of the filter element body. The outer walls of the two sliders slide against the inner wall of the housing. A cylinder slides on the inner wall of each of the two sliders. One end of each cylinder is fixed to the inner wall of the housing.

[0008] As a preferred embodiment of this utility model, the inner wall of the housing has two limiting posts that slide together, and the inner walls of the two limiting posts are matched with the outer wall of the cylinder.

[0009] As a preferred embodiment of this utility model, the inner walls of the two limiting posts are fitted with trapezoidal plates, and the two trapezoidal plates are disposed between the shell and the cover plate.

[0010] As a preferred embodiment of this utility model, each of the two trapezoidal plates has two square holes on its outer wall, and each of the four square holes has a square post fitted on its inner wall. One side of each of the four square posts is matched with the inner wall of the shell.

[0011] As a preferred embodiment of this utility model, the reinforcement mechanism includes:

[0012] Two upright blocks, one side of which is fixed to the outer wall of the shell, and one side of each of the two upright blocks is provided with a groove. The inner wall of each of the two grooves is provided with a protrusion, and one side of each of the two protrusions is fixed to one end of the cover plate.

[0013] As a preferred embodiment of this utility model, a connecting post is sleeved on one side of each of the two upright blocks, and one end of each of the two connecting posts is matched with the inner wall of the protrusion.

[0014] As a preferred embodiment of this invention, the cross-sectional area of ​​the outer walls of the two protrusions is matched with the cross-sectional area of ​​the inner walls of the groove.

[0015] The beneficial effects of this utility model are:

[0016] 1. This solution separates the outer wall of the square column from the inner wall of the square hole until the square column is separated from the trapezoidal plate. The trapezoidal plate is then slid out from the inner wall of the limiting column, and the limiting column is then removed from the inner wall of the housing. Simultaneously, the inner wall of the limiting column slides against the outer wall of the cylinder, making it easier for the operator to fit the filter element body onto the inner wall of the housing. The slider fixed to the filter element body also slides on the inner wall of the housing, making it easier for the operator to replace the filter element body from the inner wall of the housing. This avoids the operator replacing the entire housing along with the fuel filter, reducing the operator's workload and improving the practicality of the device.

[0017] 2. In this solution, by fitting the outer wall of the connecting column onto one side of the upright block, one end of the connecting column is separated from the inner wall of the protrusion. The protrusion fixed on one side of the cover plate is separated from the inner wall of the groove opened on one side of the upright block, allowing the cover plate to be removed from the outer wall of the housing. This facilitates the reinforcement of the connection between the cover plate and the housing, and also makes it easier for staff to separate the cover plate from the outer wall of the housing when replacing the filter element, effectively improving the performance of the device.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-4 As shown, the present invention provides a fuel filter element for a fuel dispenser that is easy to replace, including a housing 1, a ring plate 2 fixed at one end of the housing 1, a cover plate 3 at the other end of the housing 1, an installation mechanism 4 on the inner wall of the housing 1, and a reinforcing mechanism 5 at one end of the cover plate 3.

[0026] Installation mechanism 4 includes:

[0027] The filter element body 41 is disposed on the inner wall of the housing 1. Two sliders 42 are fixed on the outer wall of the filter element body 41. The outer walls of the two sliders 42 slide against the inner wall of the housing 1. A cylinder 43 slides on the inner wall of each slider 42. One end of each cylinder 43 is fixed to the inner wall of the housing 1. Two limiting posts 44 slide on the inner wall of the housing 1. The inner walls of the two limiting posts 44 match the outer walls of the cylinders 43. A trapezoidal plate 45 is fitted on the inner wall of each limiting post 44. The two trapezoidal plates 45 are disposed between the housing 1 and the cover plate 3. Two square holes 46 are opened on the outer wall of each trapezoidal plate 45. A square post 47 is fitted on the inner wall of each of the four square holes 46. One side of each square post 47 matches the inner wall of the housing 1, which facilitates the replacement of the filter element body 41 from the inner wall of the housing 1 by the operator, and avoids the operator replacing the housing 1 together with the fuel filter when replacing the fuel filter.

[0028] As attached Figure 1 , Figure 2 and Figure 4 As shown, the reinforcement mechanism 5 includes:

[0029] Two upright blocks 51 are provided, one side of which is fixed to the outer wall of the housing 1. A groove 52 is provided on one side of each of the two upright blocks 51. A protrusion 53 is provided on the inner wall of each of the two grooves 52. One side of each of the two protrusions 53 is fixed to one end of the cover plate 3. A connecting post 54 is fitted on one side of each of the two upright blocks 51. One end of each of the two connecting posts 54 is matched with the inner wall of the protrusion 53. The cross-sectional area of ​​the outer wall of each of the two protrusions 53 is matched with the cross-sectional area of ​​the inner wall of the groove 52. This facilitates the reinforcement of the connection between the cover plate 3 and the housing 1, and also makes it easier for the staff to separate the cover plate 3 from the outer wall of the housing 1 when replacing the filter element body 41.

[0030] Working principle: In use, the outer wall of the connecting post 54 is fitted onto one side of the upright block 51, so that one end of the connecting post 54 is separated from the inner wall of the protrusion 53. The protrusion 53 fixed on one side of the cover plate 3 is separated from the inner wall of the groove 52 opened on one side of the upright block 51, so that the cover plate 3 can be removed from the outer wall of the housing 1. This facilitates the reinforcement of the connection between the cover plate 3 and the housing 1, and also makes it easier for the staff to separate the cover plate 3 from the outer wall of the housing 1 when replacing the filter element body 41. The outer wall of the square post 47 is separated from the inner wall of the square hole 46 until the square post is removed. Separate from trapezoidal plate 45, slide trapezoidal plate 45 out from inner wall of limiting post 44, and then remove limiting post 44 from inner wall of housing 1. At the same time, inner wall of limiting post 44 slides against outer wall of cylinder 43, which makes it easier for staff to use filter element body 41 to fit on inner wall of housing 1. The slider 42 fixed to filter element body 41 slides on inner wall of housing 1, which makes it easier for staff to replace filter element body 41 from inner wall of housing 1, and avoids replacing housing 1 together with filter element when replacing fuel filter.
