Description

Technical Field

[0001] The present invention relates to the field of door guardrails, and particularly to a door railing that can be heightened. Background Art

[0002] Families with young children or pets attach great importance to the safety of the home environment. Due to the natural curiosity of young children, they will play in places such as the kitchen and the stairway, which is prone to potential safety hazards. In addition, families with pets also need to separate the areas where pets and people live. Therefore, more and more families have started to install door guardrails to enclose areas where young children or pets in the home may go, preventing danger or annoyance.

[0003] Since the height of the door railing is limited at the time of factory production, users with different height requirements need to purchase corresponding height guardrails. In actual use, for example, when the pet is small, a lower height door railing can also meet the user's needs. However, as the pet grows, its ability to climb over the railing becomes more prominent. At this time, the traditional door railing cannot be heightened, and users need to select a higher height door railing to replace the original one again, which will inevitably increase the pet-raising expenses of users. In addition, the existing door railings can generally only enclose the doorway (such as the door passage) or the stairway. When it is necessary to divide the space in the middle of the room, when the existing door railings are used in connection with the fences, they cannot stand firmly on the ground and are easily knocked down by pets.

[0004] Therefore, the existing door railings need to be further optimized and improved. Summary of the Invention

[0005] The purpose of the present invention is to provide a door railing that can reach the ceiling and the floor and can be heightened as needed.

[0006] To achieve the above purpose, the present invention adopts the following scheme: A height-adjustable door railing includes symmetrically arranged left and right columns. The bottoms of the two columns stand on the ground, and the tops of the two columns can be telescopically abutted against the ceiling. On each of the two columns, there is respectively hinged a pair of door leaves in a grid shape that can cooperate to open or close. On one of the pair of door leaves, there is a lock groove, and on the other pair of door leaves, there is a door bolt member that can be inserted into the lock groove when the two pairs of door leaves cooperate to close, locking the two pairs of door leaves so that they cannot be opened randomly. On the tops of the two pairs of door leaves, there are respectively provided a number of insertion holes, and on the bottoms of the two pairs of door leaves, there are respectively provided a number of snap fasteners corresponding to the insertion holes. Above the two pairs of door leaves, another pair of door leaves that are also hinged to the corresponding side columns can be connected respectively. The snap fasteners at the bottoms of the pair of door leaves on the same side are inserted and fixed with the insertion holes at the tops of the other pair of door leaves on the same side.

[0007] As a further solution of the present invention, the upright column includes a bottom column and a middle column that are inserted into each other in a tubular shape, and a top column that is telescopically inserted at the top of the middle column. At the position of the top of the middle column, there is a telescopic locking part for locking the telescopic height of the top column relative to the middle column.

[0008] As a preferred solution of the present invention, the telescopic locking part includes a fixed sleeve sleeved on the top of the middle column. The central axis of the fixed sleeve is coaxial with that of the middle column and penetrates up and down. One end of the top column passes through the center of the fixed sleeve and then is inserted downward from the top of the middle column. A clamping plate that can move up and down is movably arranged in the fixed sleeve. The center of the clamping plate has a vertical through hole. The clamping plate is sleeved on the circumferential outer wall of the top column through the vertical through hole. A first spring is sleeved on the circumferential outer wall of the top column above the clamping plate. One end of the first spring abuts against the inner wall top of the fixed sleeve, and the other end of the first spring abuts against the upper side of the clamping plate. A rectangular groove is penetrated on the outer wall of the fixed sleeve. A dial extends outward through the rectangular groove on the outer wall of the clamping plate. A fulcrum is arranged on the outer wall of the clamping plate away from the dial. An anchoring groove for the fulcrum to insert is arranged on the outer wall of the fixed sleeve away from the rectangular groove.

[0009] As a further solution of the present invention, a dial that can horizontally move and then block the opening of the locking groove is arranged on the locking groove.

[0010] As a preferred solution of the present invention, the locking groove includes a clamping seat A that can be stuck on the grille of the double-leaf door. Hook grooves with upward openings are respectively arranged on the front and rear side wall surfaces of the clamping seat A. A guiding groove is arranged on the top of the clamping seat A. The dial is movably arranged in the guiding groove. The door bolt member includes a clamping seat B that can be stuck on the grille of the double-leaf door. Door bolts are respectively rotatably arranged on the front and rear wall surfaces of the clamping seat B. One end of the door bolt extends into the hook groove and can enter and exit from the opening above the hook groove as it flips. The dial can block the opening above one of the hook grooves after the door bolt flips into the hook groove.

[0011] As a preferred solution of the present invention, snap holes that can communicate with each other are horizontally penetrated at the position where the bottom column and the middle column are inserted into each other. A V-shaped snap is arranged in the bottom column or the middle column. One end of the V-shaped snap has a convex spherical ball, and the ball passes through the mutually communicated snap holes after the bottom column and the middle column are inserted into each other.

[0012] As a preferred solution of the present invention, a rotating seat is arranged at the bottom end of the upright column, a friction pad for adjusting the height is arranged at the top end of the upright column. A shaft tube that can accommodate the bottom end of the upright column to insert and rotate is arranged on the rotating seat. A bolt is fixedly connected to the bottom surface of the friction pad. A threaded hole that can be threadedly connected with the bolt is arranged at the top end of the upright column.

[0013] As a preferred embodiment of the present invention, the double-leaf door includes an upper frame and a lower frame which are arranged at intervals up and down. Between the upper frame and the lower frame, a number of guardrails arranged at intervals are connected to each other. At one end of the upper frame and the lower frame, there is a bushing that can be rotatably sleeved on the circumferential outer wall of the corresponding upright column. The jack is arranged on the top surface of the upper frame, and the plug is arranged on the bottom surface of the lower frame.

[0014] As a preferred embodiment of the present invention, on the circumferential edge of the bottom of the bushing near the rotary seat, there is a lower inclined surface, and on the circumferential edge of the top of the shaft tube, there is an upper inclined surface that can cooperate with the lower inclined surface.

[0015] As a preferred embodiment of the present invention, on the upper inclined surface, there are multiple groups of symmetric notches, and on the lower inclined surface, there are bumps that can be rotated with the lower frame and snap into different positions of the notches.

[0016] In summary, the beneficial effects of the present invention compared with the prior art are as follows: Through the scheme of rotatably installing double-leaf doors on two telescopic upright columns respectively, the effect of installing a door fence in any space can be achieved. Supported by two upright columns that can reach the ceiling and the floor, and combined with a fence to enclose an isolation space, even if the door fence is squeezed and collided, it will not cause the door fence to fall down and the problem of isolation failure will not occur. In addition, by setting the jack and the plug on the double-leaf door, it is convenient for users to increase the height of the door fence at any time according to their needs in the later stage, reducing the cost of repurchasing the door fence. The dial on the bolt can effectively form the function of a second lock to prevent the double-leaf door from being accidentally opened. BRIEF DESCRIPTION OF THE DRAWINGS

These relational terms are used to facilitate the description of the relationship between some elements or features in the drawings and other elements or features. These spatial relational terms include different orientations of the device during use or operation and the orientations described in the drawings. The device may be rotated 90 degrees or other orientations, and the spatially relative adjectives used may be interpreted in the same way. Therefore, it should not be construed as a limitation of the present invention. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: As Figures 1 to 9 shown, a height-adjustable gate includes symmetrically arranged left and right columns 1. The bottom ends of the two columns 1 are provided with rotating seats 17 standing on the ground. The top ends of the two columns 1 are provided with friction pads 18 capable of adjusting the height, and the top ends of the columns 1 are telescopically abutted against the ceiling. On the two columns 1, there are respectively hinged grid-shaped double-leaf doors 2 that can cooperate with each other to open or close. A lock groove 6 is provided on one of the double-leaf doors 2, and a bolt member 3 is provided on the other double-leaf door 2, which can be inserted into the lock groove 6 when the two double-leaf doors 2 cooperate to close, locking the two double-leaf doors 2 so that they cannot be opened casually. A dial button 61 capable of horizontally translating and thus blocking the opening of the lock groove 6 is provided on the lock groove 6. A number of jacks 21 are respectively provided at the tops of the two double-leaf doors 2, and a number of buckles 22 corresponding to the jacks 21 are respectively provided at the bottoms of the two double-leaf doors 2. Above the two double-leaf doors 2, another double-leaf door 2 hinged to the corresponding side column 1 can be connected respectively. The buckles 22 at the bottoms of the double-leaf doors 2 on the same side are inserted and fixed with the jacks 21 at the tops of another double-leaf door 2 on the same side. In this embodiment, the buckle 22 is composed of two symmetrically arranged hooks. After passing through the jack 21, the hooks are respectively hooked on the left and right inner walls of the jack 21. Through the cooperation of the buckle 22 and the jack 21, two or more independent double-leaf doors 2 can be assembled on one column 1 to form a door leaf with a higher height, so that the height of the gate is superimposed. The structure is simple. Compared with the traditional gate, it is more convenient to use. The height of the gate can be flexibly increased on the basis of the original gate according to actual personal needs without having to repurchase and customize the gate, reducing unnecessary expenses.

[0030] Among them, in order to use the gate in more scenarios, the upright column 1 includes a bottom column 11 and a middle column 12 that are inserted into each other in a tubular shape, and a top column 13 that is telescopically inserted at the top of the middle column 12. At the position of the top of the middle column 12, there is a telescopic locking part 5 that can lock the telescopic height of the top column 13 relative to the middle column 12. By assembling the upright columns 1 inserted together, the self-adjustment of the installation height required in different scenarios is effectively realized. Horizontally penetrating through the position where the bottom column 11 and the middle column 12 are inserted into each other are snap holes 14 that can communicate with each other. Inside the bottom column 11 or the middle column 12, there is a V-shaped snap 15. One end of the V-shaped snap 15 has a convex spherical ball 16. After the bottom column 11 and the middle column 12 are inserted into each other, the ball 16 passes through the mutually communicating snap holes 14. The V-shaped snap 15 is used to connect between the pipes, facilitating installation, disassembly, and transportation. On the rotating seat 17, there is a shaft tube 171 that can accommodate the bottom end of the upright column 1 to be inserted and rotated. A bolt 181 is fixedly connected to the bottom surface of the friction pad 18. At the top of the upright column 1, there is a threaded hole 182 that can be threadedly connected to the bolt 181. On the peripheral edge of the bottom of the bushing 25 near the rotating seat 17, there is a lower inclined surface 251. On the peripheral edge of the top of the shaft tube 171, there is an upper inclined surface 252 that can cooperate with the lower inclined surface 251. On the upper inclined surface 252, there are multiple groups of symmetric notches 253. On the lower inclined surface 251, there are bumps 254 that can be rotated and locked into different positions of the notches 253 as the lower frame 24 rotates. The cooperation of the upper inclined surface 252 and the lower inclined surface 251 can enable the left and right double-opening door leaves 2 to automatically close when the user enters and exits, preventing potential hazards caused by the user forgetting to close the door. The cooperation of the bumps 254 and the notches 253 can fix the opening and closing angle required for the double-opening door leaves 2 when the double-opening door leaves 2 need to be fully opened. The design of this part is basically the same as the prior art and will not be elaborated here.

[0031] In addition, the double-opening door leaf 2 includes an upper frame 23 and a lower frame 24 that are arranged at intervals up and down. Between the upper frame 23 and the lower frame 24, a number of guardrails 241 that are arranged at intervals are connected. At one end of the upper frame 23 and the lower frame 24, there are bushings 25 that can be rotatably sleeved on the circumferential outer wall of the corresponding upright column 1. The jack 21 is arranged on the top surface of the upper frame 23, and the snap 22 is arranged on the bottom surface of the lower frame 24.

[0032] Specifically, the telescopic locking portion 5 includes a fixing sleeve 51 sleeved on the top of the middle column 12, the central axis of the fixing sleeve 51 is coaxial with the middle column 12, and is penetrated from top to bottom, one end of the top column 13 passes through the center of the fixing sleeve 51 and is inserted downward from the top of the middle column 12, a clamping plate 52 that can move up and down is movably provided in the fixing sleeve 51, and a vertical through hole 53 is provided in the center of the clamping plate 52, the clamping plate 52 is sleeved on the circumferential outer wall of the top column 13 through the vertical through hole 53, a first spring 54 is provided on the outer wall of the circumferential outer wall of the top column 13 above the clamping plate 52, one end of the first spring 54 is pressed against the top of the inner wall of the fixing sleeve 51, and the other end of the first spring 54 is pressed against the top of the clamping plate 52, a rectangular groove 55 is penetrated on the outer wall of the fixing sleeve 51, a paddle 56 is extended outwardly through the rectangular groove 55 on the outer wall of the clamping plate 52, and a side outer wall of the clamping plate 52 away from the paddle 56 is provided A fulcrum 57 is provided on the top, and an anchoring groove 58 capable of accommodating the insertion of the fulcrum 57 is provided on the outer wall of the fixing sleeve 51 away from the rectangular groove 55. When one end of the top column 13 passes through the center of the fixing sleeve 51 and is inserted downward from the top of the middle column 12, the first spring 54 will apply force downward to push the card plate 52 downward, and one end of the card plate 52 is fixed by the fulcrum 57, and the other end with the paddle 56 extended will sink downward, causing the card plate 52 to be in an inclined state, and the top column 13 trapped by the vertical through hole 53 is stuck and cannot move anymore. When adjustment is needed, one end of the paddle 56 is manually lifted upward to make the card plate 52 horizontal, and the top column 13 can move freely up and down from the vertical through hole 53, thereby completing the height adjustment of the column 1 to be suitable for ceilings of different heights. In this way, even if the door railing is installed in the center of the room, the upright column 1 can make the door railing very firm without tipping over.

[0033] In this embodiment, the lock slot 6 includes a seat A62 that can be clamped on the guardrail 241 of one of the split door leaves 2, and hook slots 63 with openings upward are respectively provided on the front and rear side walls of the seat A62, and a guide slot 64 is provided on the top of the seat A62. The dial button 61 is movably arranged in the guide slot 64, and the door bolt member 3 includes a seat B31 that can be clamped on the guardrail 241 of the other split door leaf 2, and a door bolt 32 is rotatably provided on the front and rear walls of the seat B31, one end of the door bolt 32 extends into the hook slot 63 and can enter and exit from the opening above the hook slot 63 as it is flipped. The dial button 61 can close the opening above one of the hook slots 63 after the door bolt 32 flips into the hook slot 63. When it is necessary to lock two relatively closed split door leaves, the door bolt 32 is rotated into the hook slot 63, and then the dial button 61 is turned to close the opening of the hook slot 63.
