Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more particularly to a quick-install filter. Background Art

[0002] The existing filter includes a cylinder, an upper cover and a lower cover. The lower cover is welded to the bottom of the cylinder, and the upper cover and the cylinder are generally connected by bolts and nuts. Specifically, a flange is provided on the edge of the upper cover, and a flange is provided on the top edge of the cylinder. The flange is provided with a number of connection holes distributed circumferentially, and the bolts and nuts are connected through the connection holes. The connection method of this flange structure has the following disadvantages: there are many bolts and nuts, and when disassembling, the bolts and nuts need to be completely removed, which is very time-consuming and laborious. In addition, the removed bolts and nuts must be stored in a container to avoid being easily lost. Therefore, it is necessary to improve the structure and propose a quick-install filter. Utility Model Content

[0003] The purpose of the present invention is to provide a quick-install filter in order to solve the above technical problems.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0005] A quick-install filter comprises a cylinder and an upper cover, wherein a plurality of locking members are distributed circumferentially on the edge of the cylinder, and the locking members are used to lock and fix the upper cover and the cylinder;

[0006] The locking member includes a locking rod, a limiting plate, a fixing plate and a tightening cap;

[0007] The locking rod includes a screw and a connecting sleeve, and the bottom end of the screw is welded to the connecting sleeve;

[0008] There are two fixing plates and they are symmetrically arranged. The fixing plates are welded to the top edge of the cylinder. Bolts are arranged on the fixing plates. The bolts are sleeved with the connecting sleeves and the bolts are fixed to the fixing plates by nuts.

[0009] There are two limit plates, which are symmetrically distributed and are welded to the upper cover.

[0010] The tightening cap comprises a tightening sleeve, a base plate and a circular ring. The tightening sleeve is connected to the screw rod. The top edge of the tightening sleeve is welded to the circular ring, and the bottom edge of the tightening sleeve is welded to the base plate.

[0011] When the upper cover and the cylinder need to be locked and fixed, flip the screw upwards and rotate the ring so that the bottom plate and the limit plate are close to each other, and the bottom plate and the limit plate are clamped and fixed;

[0012] When the upper cover and the cylinder need to be released from the fixation, the ring is rotated so that the bottom plate leaves the limit plate, and the screw is flipped downward to complete the contact fixation.

[0013] The bottom of the cylinder is equipped with at least three circumferentially distributed support legs with a triangular cross-section. Support plates are welded to the bottom of the legs, and one end of the legs is welded to the cylinder. The support legs support and secure the cylinder, and the triangular cross-section of the legs ensures a stable support at the bottom of the filter and prevents deformation.

[0014] The cylinder and the upper cover are made of stainless steel.

[0015] The surfaces of the cylinder and upper cover are both coated with a composite protective coating comprising a polyurethane coating, an epoxy resin coating, and a polyurethane coating. This composite protective coating effectively isolates the stainless steel from direct contact with the external environment, preventing corrosion from external substances and improving the filter's high-temperature and corrosion resistance.

[0016] The beneficial effects of the utility model are as follows:

[0017] By setting the locking piece, when opening the upper cover, the screw does not need to be completely unscrewed to flip open, making disassembly or installation quick and time-saving and labor-saving, and there is no need to find another place to store it to avoid loss.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1 to 3 As shown, this embodiment provides a quick-install filter, including a cylinder 1 and an upper cover 2. A plurality of locking members 3 are distributed circumferentially on the edge of the cylinder 1. The locking members 3 are used to lock and fix the upper cover 2 and the cylinder 1.

[0026] The locking member 3 includes a locking rod, a limiting plate 4, a fixing plate 5 and a tightening cap;

[0027] The locking rod includes a screw rod 6 and a connecting sleeve 7, and the bottom end of the screw rod 6 is welded to the connecting sleeve 7;

[0028] There are two fixing plates 5 and they are symmetrically arranged. The fixing plates 5 are welded to the top edge of the cylinder 1. Bolts 8 are provided on the fixing plates 5. The bolts 8 are sleeved with the connecting sleeves 7. The bolts 8 are fixed to the fixing plates 5 by nuts.

[0029] The number of the limiting plates 4 is 2 and they are symmetrically distributed. The limiting plates 4 are welded to the upper cover 2.

[0030] The tightening cap includes a tightening sleeve 9, a base plate 10 and a ring 11. The tightening sleeve 9 is connected to the screw rod 6. The top edge of the tightening sleeve 9 is welded to the ring 11, and the bottom edge of the tightening sleeve 9 is welded to the base plate 10.

[0031] When the upper cover 2 and the barrel 1 need to be locked and fixed, the screw 6 is turned upward and the ring 11 is rotated so that the bottom plate 10 and the limit plate 4 are close to each other, and the bottom plate 10 and the limit plate 4 are clamped and fixed;

[0032] When the upper cover 2 and the barrel 1 need to be released from their fixation, the ring 11 is rotated to allow the bottom plate 10 to leave the limiting plate 4 and the screw 6 is flipped downward to complete the contact fixation.

[0033] The bottom of the cylinder 1 is provided with at least three circumferentially distributed support legs 12, each having a triangular cross-section. A support plate 13 is welded to the bottom of the support legs 12, and one end of the support legs 12 is welded to the cylinder 1. The support legs 12 are provided to support and fix the cylinder 1, and the triangular cross-section of the support legs 12 ensures that the filter bottom is supported stably and is not easily deformed.

[0034] The cylinder 1 and the upper cover 2 are made of stainless steel.

[0035] The surfaces of the cylinder 1 and the upper cover 2 are both provided with a composite protective coating, which includes a polyurethane coating 14, an epoxy resin coating 15, and a polyurethane coating 14. The composite protective coating can effectively isolate the stainless steel from direct contact with the external environment, prevent the corrosion of the stainless steel by external substances, and improve the high temperature resistance and corrosion resistance of the filter.
