Description

Technical Field

[0001] The present invention relates to the technical field of pet cabinets, and in particular to a multifunctional pet display cabinet with an adjustable structure. Background Art

[0002] Pet cabinets are used to store and house pets in pet shops. Existing pet cabinets typically consist of a cabinet body divided from top to bottom by horizontal panels into multiple equally sized spaces. Observation windows made of acrylic or glass are installed on the front of these spaces. Because pets have short growth cycles and vary greatly in size between pets of different ages, the spaces within these cabinets need to be adjusted accordingly. Most existing pet cabinets have fixed spaces, making them difficult to adjust based on actual needs. Adjustment in some adjustable pet cabinets requires removing the horizontal panels with a screwdriver. This also requires removing the observation windows, which must then be adjusted and installed at the appropriate height, making the overall installation process more complex. The changing height of the horizontal panels can result in the observation windows being at an inappropriate height, increasing or decreasing the aperture between adjacent horizontal panels. This can cause some observation windows to be located between the two panels, leading to the possibility of opening both windows simultaneously when accessing a pet. To address this issue, a multifunctional pet display cabinet with an adjustable structure has been designed. Summary of the Invention

[0003] The present invention provides a multifunctional pet display cabinet with an adjustable structure, which solves the above-mentioned problem.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: The multifunctional pet display cabinet with an adjustable structure includes a cabinet body, wherein each of the four corners of the cabinet body is fixed with a column, and the column is provided with a rope threading groove of a convex structure, and the rope threading groove is connected to the outside of the column. A lower display cabinet is fixed below the four columns, and a lifting seat is slidably installed up and down in the middle between the four columns. An upper display cabinet is fixed above the lifting seat, and a groove is provided at the bottom of the lifting seat. A bottom plate is fixed below the lifting seat, and an installation cavity is formed between the bottom plate and the groove. A winding roller is rotatably installed in the installation cavity through a bearing, and an unlocking structure is slidably installed on the winding roller back and forth. A lifting rope is respectively fixed at the top of the rope threading groove of the four columns, and a plurality of guide rollers are provided in the installation cavity.

The bottom end of the upper sealing plate is below the top of the positioning groove on the uprights and does not block the positioning groove. An upper shield is fixed between the two upright frames on the left and between the two upright frames on the right respectively. The upright frames and the upper shield are in sliding contact with the upper sealing plate. A lower shield is provided on the left and right sides below the bottom plate. The lower shield is in sliding contact with the lower sealing plate, which can close the space between the two upright columns on the left and the two upright columns on the right to prevent pet hair from entering the holes and grooves on the upright columns.

[0007] Preferably, a take-up wheel is fixed on the front and rear sides of the outer ring of the winding roller, and four lifting ropes are respectively wound around the two take-up wheels. The same take-up wheel is divided into two parts by a partition plate, and the two lifting ropes are staggered and wound around the two parts respectively. The two lifting ropes on the left side are wound around the take-up wheel from top to bottom and fixed, and the lifting rope on the right side is wound around the take-up wheel from bottom to top and fixed. When the winding roller drives the take-up wheel to rotate clockwise together, the lifting rope can be wound around the take-up wheel. As the lifting rope is gradually wound around the take-up wheel, the length of the lifting rope hanging is reduced, thereby causing the height of the lifting seat to move upward and increase. The internal cavity of the winding roller is set to form a moving cavity. A circular hole is opened at the front end of the winding roller, and the circular hole is connected to the moving cavity. The outer ring surface of the winding roller is opened with four groups of through-holes distributed in a circular array, and the through-holes are connected to the moving cavity.

The tension spring makes the pull rod always have a tendency to move backward.

[0009] Preferably, a notch is provided on the front side of the lifting seat, the notch is connected to the installation cavity, a storage box is fixed by screws in the notch, a pull opening is provided on the storage box, the front end of the pull rod passes through the pull opening and extends into the storage box, and a handle is provided on the part of the pull rod placed in the storage box. When the handle is rotated clockwise one circle, the lifting seat rises one unit distance, which is the distance between two adjacent positioning grooves.

[0010] Preferably, the left and right locking plates are symmetrically arranged, and one end of the locking plate away from the limit block is slidably inserted into the through-hole, so that the locking plate can limit the rotation of the winding roller, thereby fixing the lifting rope after winding or unfolding, and the position of the lifting seat is also fixed accordingly, so that it will not fall due to accidents. Two groups of guide rods are fixed on the left and right sides of the top of the installation cavity of the lifting seat through shaft blocks respectively, and a guide block is welded above the locking plate. The left and right locking plates are respectively installed under the left and right groups of guide rods through the guide blocks. A limit spring is sleeved on the guide rod, and the two ends of the limit spring are respectively abutted against the shaft block and the guide block. The limit spring makes the locking plate always have a tendency to move toward one side of the winding roller.

The lifting rope can pass through the opening and extend into the installation cavity through the connecting port. When the lifting seat moves up and down, the lifting rope can freely extend in or out along the long strip opening without causing interference due to contact with the column.

[0013] Preferably, the limit block is mounted on the top of the base plate by sliding forward and backward on a linear track, and a limit head is integrally formed on the end of the limit block facing the column, and the limit head is inserted into the positioning groove through the connecting port, and an inclined driving groove is provided on the limit block, and a driving roller is provided below the end of the locking plate away from the winding roller, and the driving roller slides into the driving groove; When the locking plate moves toward the end away from the winding roller, the driving roller will move away from the winding roller along with the locking plate. At this time, the driving roller will push the two limit blocks closer to each other, that is, the limit head will move away from the column. When the pull rod is pulled to the front, the locking plate moves to the farthest distance, and the limit head is completely out of the positioning groove.

[0014] Beneficial effects of the present invention: 1. The lifting seat is installed by sliding it up and down between the four pillars of the cabinet body. The upper display cabinet is installed above the lifting seat. With the winding roller and four lifting ropes, the height of the lifting seat and the upper display cabinet can be directly changed by rotating the winding roller.

A locking plate is installed by sliding left and right inside the lifting seat, and an unlocking structure is provided on the winding roller. The locking plate is slidably connected to the unlocking structure. The locking plate can lock the winding roller, thereby fixing the lifting rope after winding or unfolding. The position of the lifting seat is also fixed, preventing it from falling due to accidents. 3. By sliding the limit block back and forth at the corner inside the installation cavity of the lifting seat, the limit block can be inserted into the adjacent column, thereby strengthening the fixation of the lifting seat and improving the connection strength. The limit block is slidably connected to the locking plate. When the unlocking structure is unlocked, the limit block first breaks away from the connection with the column, and then the lifting rope can be reeled or unfolded, avoiding interference with the rotation of the reeling roller.

A locking plate 8 is installed on the left and right sides of the installation cavity for sliding left and right. The locking plate 8 is movably connected to the unlocking structure 6. A limit block 9 is installed at the four corners of the installation cavity for sliding back and forth. The limit block 9 is slidably connected to the locking plate 8.

[0019] Reference Figure 1-Figure 3 The lower display cabinet 2 includes a lower seat plate 21 fixed below the four columns 12, a lower horizontal plate 23 is fixed between the two front columns 12, and a lower glass window 22 is installed on the front side between the lower horizontal plate 23 and the lower seat plate 21 through a hinge. The two lower glass windows 22 are connected and fixed by a door lock; The upper display cabinet 4 includes four vertical frames 42 fixed at the four corners above the lifting base 3. An upper horizontal plate 43 is fixed above the two front vertical frames 42. An upper glass window 41 is rotatably mounted between the two front vertical frames 42 via a hinge. The two upper glass windows 41 are connected and fixed by a door lock. A corrugated plate 11 is connected to the top front side of the cabinet body 1, and the lower end of the corrugated plate 11 is connected to the upper horizontal plate 43. A corrugated plate 11 is connected to the bottom of the lifting seat 3, and the lower end of the corrugated plate 11 is connected to the lower horizontal plate 23. When the lifting seat 3 adjusts the surface height up and down, the corrugated plate 11 can be folded or unfolded accordingly, thereby being able to cover part of the upper display cabinet 4 and the lower display cabinet 2.

[0020] An upper sealing plate 13 is fixed between the two left columns 12 and the upper parts of the two right columns 12, and a lower sealing plate 14 is fixed between the two left columns 12 and the lower parts of the two right columns 12. The bottom end of the upper sealing plate 13 is below the top of the positioning groove 122 on the column 12 and does not block the positioning groove 122. An upper shield plate 44 is fixed between the two upright frames 42 on the left and between the two upright frames 42 on the right. The upright frames 42 and the upper shield plate 44 are in sliding contact with the upper sealing plate 13. A lower shield plate 31 is provided on both sides below the bottom plate 33. The lower shield plate 31 is in sliding contact with the lower sealing plate 14, which can close the space between the two upright columns 12 on the left and the two upright columns 12 on the right to prevent pet hair from entering the holes and grooves on the upright columns 12.

[0021] Reference Figure 4-Figure 7 , a take-up wheel 52 is fixed on the front and rear sides of the outer ring of the winding roller 5, and the four lifting ropes 7 are respectively wound around the two take-up wheels 52. The same take-up wheel 52 is divided into two parts by a partition, and the two lifting ropes 7 are staggered and wound around the two parts respectively. The two lifting ropes 7 on the left are wound around the take-up wheel 52 from top to bottom and fixed, and the lifting rope 7 on the right is wound around the take-up wheel 52 from bottom to top and fixed. When the winding roller 5 drives the take-up wheel 52 to rotate clockwise together, the lifting rope 7 can be wound around the take-up wheel 52. As the lifting rope 7 is gradually wound around the take-up wheel 52, the hanging length of the lifting rope 7 is reduced, thereby causing the height of the lifting seat 3 to move upward and increase; The internal cavity of the winding roller 5 is set to form a moving cavity. A circular hole is opened at the front end of the winding roller 5, and the circular hole is connected to the moving cavity. The outer ring surface of the winding roller 5 is opened with four groups of through-holes 51 distributed in a circular array, and the through-holes 51 are connected to the moving cavity.

[0022] The unlocking structure 6 includes a pull rod 61 that is slidably inserted into the movable cavity through a circular hole. A cross-shaped connecting frame 63 is fixed to the outer ring of the pull rod 61. An unlocking sleeve 62 is slidably sleeved on the outer ring surface of the winding roller 5. The connecting frame 63 passes through the through-hole 51 and is fixed to the inner ring of the unlocking sleeve 62. The connecting frame 63 includes a circular ring and four sliders distributed in an annular array on the outer ring of the circular ring. The circular ring is slidably placed in the movable cavity, and the four sliders are slidably placed in the four through-holes 51 respectively, and the sliders are fixed to the inner wall of the unlocking sleeve 62; A tension spring 64 is sleeved on the pull rod 61, one end of the tension spring 64 is fixed to the connecting frame 63, and the other end of the tension spring 64 is fixed to the inner wall of the rear side of the moving cavity of the winding roller 5. The tension spring 64 makes the pull rod 61 always have a tendency to move backward.

[0023] A notch is provided on the front side of the lifting seat 3, which is connected to the installation cavity. A storage box 32 is fixed by screws in the notch. A pull opening is provided on the storage box 32. The front end of the pull rod 61 passes through the pull opening and extends into the storage box 32. A handle is provided on the part of the pull rod 61 placed in the storage box 32. When the handle is rotated clockwise once, the lifting seat 3 rises a unit distance, which is the distance between two adjacent positioning grooves 122.

[0024] Reference Figure 4-Figure 9The left and right locking plates 8 are symmetrically arranged, and the end of the locking plate 8 away from the limit block 9 is slidably inserted into the through-hole 51. The locking plate 8 can limit the rotation of the winding roller 5, thereby fixing the lifting rope 7 after winding or unfolding, and the position of the lifting seat 3 is also fixed accordingly, so that it will not fall due to accidents. Two groups of guide rods 81 are fixed on the left and right sides of the top of the installation cavity of the lifting seat 3 through the shaft block. A guide block 82 is welded above the locking plate 8. The left and right locking plates 8 are respectively installed under the left and right groups of guide rods 81 through the guide block 82. A limit spring 83 is sleeved on the guide rod 81. The two ends of the limit spring 83 are respectively abutted against the shaft block and the guide block 82. The limit spring 83 makes the locking plate 8 always have a tendency to move toward the side of the winding roller 5.

[0025] The rear half of the locking plate 8 facing the winding roller 5 is inclined to form a contact inclined surface 85, and the front half of the locking plate 8 facing the winding roller 5 is horizontally set to form a contact surface, and a plurality of bull's eye balls are movably embedded in the contact surface. The front end of the unlocking sleeve 62 is provided with a tapered surface 621, and the slope of the tapered surface 621 is the same as the slope of the contact inclined surface 85. When the unlocking sleeve 62 moves forward under the action of the pull rod 61, the contact inclined surface 85 contacts the tapered surface 621, thereby pushing the locking plates 8 on the left and right sides to move along the guide rod 81 toward the end away from the winding roller 5, and the outer ring surface of the unlocking sleeve 62 rolls in contact with the bull's eye balls on the contact surface. At this time, the pull rod 61 is pulled to the front and the locking plate 8 moves to the farthest distance. At this time, when the winding roller 5 drives the unlocking sleeve 62 to rotate, the bull's eye balls will roll in contact with the outer ring surface of the unlocking sleeve 62, and will not interfere with the normal rotation of the unlocking sleeve 62.

[0026] The column 12 has a plurality of linearly distributed positioning grooves 122 on the side facing the limit block 9 from top to bottom. The positioning grooves 122 are connected to the rope threading groove 121. A connecting port is formed at each of the four corners of the lifting seat 3. The connecting port is connected to the installation cavity, and the lifting rope 7 extends into the installation cavity of the lifting seat 3 through the connecting port. The positioning groove 122 is divided into two parts by the rope threading groove 121 from the middle to form a long strip opening. The lifting rope 7 can pass through the opening and extend into the installation cavity through the connecting port. When the lifting seat 3 moves up and down, the lifting rope 7 can freely extend or extend along the long strip opening without contacting the column 12 and causing interference.

[0027] The limit block 9 is mounted on the top of the bottom plate 33 by sliding forward and backward on a linear track. The limit block 9 has an integrally formed limit head 91 on the end facing the column 12. The limit head 91 passes through the connection port and is inserted into the positioning groove 122. An inclined driving groove 92 is provided on the limit block 9. A driving roller 84 is provided below the end of the locking plate 8 away from the winding roller 5. The driving roller 84 slides and extends into the driving groove 92. When the locking plate 8 moves toward the end away from the winding roller 5, the driving roller 84 will move away from the winding roller 5 together with the locking plate 8. At this time, the driving roller 84 will push the two limit blocks 9 closer to each other, that is, the limit head 91 will move away from the column 12. When the pull rod 61 is pulled to the front side, the locking plate 8 moves to the farthest distance, and the limit head 91 is now completely out of the positioning groove 122.

[0028] When the unlocking sleeve 62 moves forward under the action of the pull rod 61, the contact inclined surface 85 will contact with the tapered surface 621, and the tapered surface 621 will push the locking plates 8 on the left and right sides to move along the guide rod 81 toward the end away from the winding roller 5; When the locking plate 8 moves toward the end away from the winding roller 5 under the action of the unlocking sleeve 62, the driving roller 84 on the locking plate 8 will move away from the winding roller 5 together with the locking plate 8. At this time, the driving roller 84 will push the two limit blocks 9 to move closer to each other, that is, the limit head 91 moves away from the column 12; When the handle is pulled outward to detach from the storage box 32, the pull rod 61 is pulled to the frontmost side. At this time, the locking plate 8 moves to the farthest distance, and the limit head 91 is completely separated from the positioning groove 122 on the column 12. At this time, the outer ring surface of the unlocking sleeve 62 rolls with the bull's eye ball on the contact surface. At this time, when the winding roller 5 drives the unlocking sleeve 62 to rotate, the bull's eye ball rolls with the outer ring surface of the unlocking sleeve 62 and does not interfere with the normal rotation of the unlocking sleeve 62. After that, the pull rod 61 can be rotated clockwise for several turns (the number of turns is a full turn). Since the pull rod 61 is linearly slidably connected to the take-up roller 5 through the connecting frame 63, the take-up roller 5 will rotate clockwise together with the pull rod 61. The two side lifting ropes 7 are wound from top to bottom and fixed on the take-up wheel 52, and the lifting rope 7 on the right is wound from bottom to top and fixed on the take-up wheel 52. When the take-up roller 5 drives the take-up wheel 52 to rotate clockwise together, the lifting rope 7 can be wound and reeled on the take-up wheel 52. As the lifting rope 7 is gradually reeled on the take-up wheel 52, the hanging length of the lifting rope 7 is reduced, thereby causing the height of the lifting seat 3 to move upward and increase. When the lifting base 3 moves upward, the upper display case 4 located above the lifting base 3 will also move upward. During the upward movement, the heights of the corrugated plates 11 on the upper and lower sides will change accordingly, thereby partially shielding the upper display case 4 and the lower display case 2. After the lifting seat 3 is moved to the desired height, the handle is made horizontal, and the pull rod 61 is slowly pushed backward through the handle. As the pull rod 61 moves backward, the unlocking sleeve 62 will also move backward. Since the locking plate 8 always has a tendency to move toward the winding roller 5 under the action of the limit spring 83, when the unlocking sleeve 62 moves backward, the locking plate 8 will gradually approach the winding roller 5. During this process, the two limit blocks 9 on the same side will move away from each other and gradually approach the adjacent column 12. When the pull rod 61 moves to the rearmost side, that is, the hand is put into the storage box 32, the unlocking sleeve 62 returns to its original position, the locking plate 8 is engaged with the through-hole 51 on the winding roller 5, and the locking plate 8 will limit the winding roller 5 so that it cannot rotate, and the limiting head 91 on the limiting block 9 will also be engaged with the positioning groove 122 of the column 12, thereby completely fixing the lifting seat 3 so that the position of the lifting seat 3 will not change. At this time, the height adjustment of the entire upper display cabinet 4 can be completed.

[0029] The lifting seat 3 is installed by sliding up and down between the four uprights 12 of the cabinet body 1, and the upper display cabinet 4 is installed above the lifting seat 3. The winding roller 5 and the four lifting ropes 7 are provided. The height of the lifting seat 3 and the upper display cabinet 4 can be directly changed by rotating the winding roller 5. The height of the upper display cabinet 4 can be quickly adjusted as needed, which improves convenience. After the height is adjusted, the height of the observation windows on the upper display cabinet 4 and the lower display cabinet 2 remains unchanged, which is convenient for displaying and taking out the pets inside. By slidingly installing a locking plate 8 in the lifting seat 3, an unlocking structure 6 is provided on the winding roller 5. The locking plate 8 is slidably connected to the unlocking structure 6. The locking plate 8 can lock the winding roller 5, thereby fixing the lifting rope 7 after winding or unwinding. The position of the lifting seat 3 is also fixed, and it will not fall due to accidents. By sliding the limit block 9 back and forth at the corner inside the installation cavity of the lifting seat 3, the limit block 9 can be inserted into the adjacent column 12, thereby strengthening the fixation of the lifting seat 3 and improving the connection strength. The limit block 9 is slidably connected to the locking plate 8. When the unlocking structure 6 is unlocked, the limit block 9 is first disconnected from the column 12, and then the lifting rope 7 can be reeled or unwound, avoiding interference with the rotation of the reeling roller 5.
