Description

Technical Field

[0001] The utility model relates to the field of molecular sieves of portable oxygen generators, in particular to a non-detachable locking mechanism of a molecular sieve. Background Art

[0002] The portable oxygen concentrator uses physical pressure swing adsorption technology. Its oxygen production principle is mainly to use an air compressor to make the oxygen and nitrogen in the air pass through the molecular sieve, and use the difference in the adsorption capacity of the molecular sieve to nitrogen and oxygen in the air to achieve the separation of nitrogen and oxygen, thereby obtaining continuous high-concentration oxygen. The effect of the molecular sieve will decrease after long-term use, and the molecular sieve in the molecular sieve tank needs to be replaced. At present, the molecular sieve tank is generally directly installed and fixed by screws. The user can freely disassemble and replace the molecular sieve tank. Since the molecular sieve tanks produced by different manufacturers are generally different, the random installation and replacement will cause certain damage to the portable oxygen concentrator, and it will also cause certain damage when non-professionals replace it, which will also cause certain impact in the subsequent manufacturer's after-sales process. To this end, we designed a non-removable locking mechanism for the molecular sieve. Utility Model Content

[0003] In order to solve the technical problem that the molecular sieve tank is easily and randomly disassembled, the utility model provides a non-disassembly locking mechanism for the molecular sieve.

[0004] The utility model adopts the following technical scheme to achieve: a non-detachable locking mechanism for a molecular sieve, comprising a mounting base, wherein the left side of the mounting base has two symmetrically distributed mounting openings formed through the upper and lower parts, and a molecular sieve cartridge is respectively installed in the two mounting openings, and a mounting bottom plate and a mounting cover are respectively installed at the lower end of the molecular sieve cartridge, and two limit plates are symmetrically arranged front and back on the left side of the lower end surface of the mounting base, and the left and right side surfaces of the limit plates are respectively integrated into a limit block 1 and a limit block 2, a locking plate is installed on the left side of the lower end surface of the mounting base by screws, a groove is opened on the left half of the lower part of the mounting base, the mounting opening is placed at the position of the groove, and the right side of the locking plate contacts the right side of the inner wall of the groove so that it cannot move left and right, and locking plates are respectively arranged at the front and rear ends of the locking plate, and a contact plate is formed on the outward side of the locking plate by an extended design, and the contact plate is placed on the upper surface of the limit block 2, and the limit plate and the contact plate both have a certain elasticity, and they can undergo a certain degree of bending deformation toward the left and right sides.

[0005] As a further improvement of the above scheme, the bottom end surface of the molecular sieve cartridge expands outward to form a convex edge, and the bottom end convex edge of the molecular sieve cartridge is pressed between the mounting base plate and the mounting cover, the mounting cover and the mounting base plate are annular in structure, and their outer diameters are larger than the inner diameter of the mounting port, and the molecular sieve cartridge passes through the mounting cover and the mounting base plate from bottom to top, and its bottom end is fixed between the mounting cover and the mounting base plate, and the mounting cover and the mounting base plate are fixed by screws, wherein the mounting cover and the left side of the mounting base plate are fixed to the mounting base by screws, and the right half is not connected.

[0006] As a further improvement of the above scheme, the cross-section of the mounting base plate is a convex-shaped structure, the upper half of the mounting base plate is placed above the limit block one, and there is a gap between the two, and a portion of the lower surface of the limit block one is cut away to form a mounting slope one, and the gap between the limit block one and the mounting base plate enables the limit plate to be bent and deflected to the left to a certain extent, thereby facilitating the contact plate to be placed above the limit block two.

[0007] As a further improvement of the above scheme, a portion of the right side surface of the limit block 2 is cut away to form a mounting bevel 2, a chamfer design is provided between the mounting bevel 2 and the upper surface of the limit block 2, and a vertically downward limiting groove is provided on the upper surface of the limit block 2, so that the contact plate can slide upward along the mounting bevel 2 and be positioned above the limit block 2.

[0008] As a further improvement of the above scheme, the bottom surface of the contact plate is recessed downward to form a sliding groove, and a limiting column is arranged in the sliding groove for sliding up and down. The cross-section of the sliding groove and the limiting column is a convex structure, and the bottom end of the limiting column extends into the limiting groove. After the contact plate slides to the top of the limiting block 2, the limiting groove will be aligned with the sliding groove. At this time, the limiting column will be inserted into the limiting groove under the action of its own gravity, so that the contact plate cannot be deformed and deflected left and right, and the locking plate cannot be removed.

[0009] As a further improvement of the above scheme, a connecting plate is integrally formed at the lower left end of the locking plate, and the front and rear sides of the connecting plate are respectively in contact with the rearward surfaces of the front and rear limit plates, and the left end of the connecting plate is below the mounting base plate, and the right side of the lower surface of the mounting base plate is in close contact with the connecting plate, so that the left end of the connecting plate can support the right side of the molecular sieve cylinder, so that the entire molecular sieve cylinder is fixed.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0022] Example:

[0023] Please combine Figure 1-Figure 5, a molecular sieve non-detachable locking mechanism of the present embodiment comprises a mounting base 1, two symmetrically distributed mounting openings are formed through the left side of the mounting base 1 from top to bottom, a molecular sieve cartridge 2 is respectively mounted in the two mounting openings, a mounting bottom plate 3 and a mounting cover 6 are mounted at the lower end of the molecular sieve cartridge 2, two limit plates 11 are symmetrically arranged front and back on the left side of the lower end surface of the mounting base 1, and the left and right side surfaces of the limit plate 11 are respectively integrated with a limit block 1 12 and a limit block 2 13, a locking plate 4 is mounted on the left side of the lower end surface of the mounting base 1 by screws, a groove is opened in the left half of the lower portion of the mounting base 1, the mounting opening is placed at the position of the groove, the right side of the locking plate 4 contacts the right side of the inner wall of the groove, so that it cannot move left and right, and locking plates 5 are respectively arranged at the front and rear ends of the locking plate 4, and a contact plate 51 is formed on the outward side of the locking plate 5, and the contact plate 51 is placed on the upper surface of the limit block 2 13, wherein the limit plate 11 and the contact plate 51 both have a certain elasticity, and they can bend and deform to a certain extent toward the left and right sides.

[0024] The bottom surface of the molecular sieve cartridge 2 extends outward to form a convex edge, and the bottom convex edge of the molecular sieve cartridge 2 is pressed between the mounting base plate 3 and the mounting cover 6. The mounting cover 6 and the mounting base plate 3 are annular in structure, and their outer diameters are larger than the inner diameter of the mounting opening. The molecular sieve cartridge 2 passes through the mounting cover 6 and the mounting base plate 3 from bottom to top, and its bottom end is fixed between the mounting cover 6 and the mounting base plate 3, and the mounting cover 6 and the mounting base plate 3 are fixed by screws, wherein the mounting cover 6 and the left side of the mounting base plate 3 are fixed to the mounting base 1 by screws, and the right half thereof is not connected.

[0025] The cross-section of the mounting base plate 3 is a convex structure, and the upper half of the mounting base plate 3 is placed above the limit block 12 with a gap therebetween. A portion of the lower surface of the limit block 12 is cut away to form a mounting slope 121. The gap between the limit block 12 and the mounting base plate 3 allows the limit plate 11 to be bent and deflected to the left to a certain extent, thereby facilitating the contact plate 51 to be placed above the limit block 13.

[0026] A second mounting slope 131 is formed by cutting away a portion of the right side surface of the limit block 13. A rounded corner is designed between the second mounting slope 131 and the upper surface of the limit block 13. A vertical downward limiting groove is provided on the upper surface of the limit block 13. The contact plate 51 can slide upward along the second mounting slope 131 and reach the top of the limit block 13.

[0027] The bottom surface of the contact plate 51 is recessed downward to form a sliding groove, and a limiting column 52 is arranged in the sliding groove for sliding up and down. The cross-section of the sliding groove and the limiting column 52 is a convex structure, and the bottom end of the limiting column 52 extends into the limiting groove. After the contact plate 51 slides above the limiting block 13, the limiting groove will be aligned with the sliding groove. At this time, the limiting column 52 will be inserted into the limiting groove at its bottom under the action of its own gravity, thereby preventing the contact plate 51 from deforming and deflecting left and right, and making the locking plate 4 unable to be removed.

[0028] A connecting plate 41 is integrally formed at the lower left end of the locking plate 4, and the front and rear sides of the connecting plate 41 are respectively in contact with the rearward surfaces of the front and rear limit plates 11, and the left end of the connecting plate 41 is below the mounting base plate 3, and the right side of the lower surface of the mounting base plate 3 is in close contact with the connecting plate 41, so that the left end of the connecting plate 41 can support the right side of the molecular sieve cylinder 2, so that the entire molecular sieve cylinder 2 is fixed.

[0029] The connecting plate 41 is provided with a mounting groove 42 , and the locking plate 5 is placed in the mounting groove 42 , and the two are connected by screws, so that the locking plate 5 can be easily replaced, thereby facilitating the subsequent installation of the molecular sieve cartridge 2 .

[0030] The implementation principle of a non-detachable locking mechanism of a molecular sieve in the embodiment of the present application is as follows: when installing the molecular sieve cartridge 2, the molecular sieve cartridge 2 is passed through the mounting cover 6 from bottom to top, and then the mounting base plate 3 is fixed to the mounting cover 6 by screws. At this time, the molecular sieve cartridge 2 will be fixed between the mounting cover 6 and the mounting base plate 3, and then the molecular sieve cartridge 2 can be passed through the two mounting openings from bottom to top and placed above the mounting base 1, and then the left end of the mounting base plate 3 is fixed to the left end of the mounting base 1 by screws (when the mounting cover 6 and the mounting base plate 3 pass through the limit blocks 12 on the two limit plates 11, the limit plates 11 need to be bent to the left until the limit blocks 12 are fixed to the mounting base 11). Figure 5 When the locking plate 4 is in the state of being moved left and right, the locking plate 51 is in the state of being moved downward, and the locking plate 51 is in the state of being moved left and right.

[0031] By installing a locking plate 4 and a locking plate 5 under the mounting base 1, the locking plate 5 is blocked by the groove, the limit plate 11 and the mounting base 3, so that it cannot move forward, backward, left, right, and it will not move downward, so that it cannot be normally disassembled. It can fix the molecular sieve cartridge 2 above, making it non-detachable, and personnel cannot disassemble it by themselves, thereby ensuring the high quality of the molecular sieve cartridge 2;

[0032] The locking plate 5 is screwed onto the locking plate 4 so that it can be easily disassembled and replaced. When the molecular sieve cartridge 2 is replaced and installed, the damaged locking plate 5 can be quickly replaced, thereby improving convenience.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
