Description

Technical Field

[0001] This utility model belongs to the field of daily necessities, and more specifically, relates to a door stopper. Background Technology

[0002] Current products use a rubber sheet that deforms elastically to compress the ground, generating pre-tension to position the door. However, this can cause problems on uneven surfaces. When encountering a raised surface, the pre-tension of the rubber sheet increases, creating a greater reaction force that can damage the product. Conversely, when encountering a recessed surface, gaps form between the rubber sheet and the ground, preventing the door from being properly positioned.

[0003] Meanwhile, the existing products are rather cumbersome to use. This includes requiring a considerable amount of time to rotate the nut to press the rubber sheet firmly against the ground, or having different positioning and unlocking procedures, which forces users to spend a long time learning and practicing, increasing user costs and impacting the user experience. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a door stop that can stably position the door even when facing an uneven surface.

[0005] This utility model discloses a gate stop, comprising a housing and a positioning mechanism disposed within the housing; the positioning mechanism includes a sliding sleeve that slides longitudinally within the housing, a friction seat that slides longitudinally on the sliding sleeve, and a preload spring installed between the sliding sleeve and the friction seat; a pressing plate that drives the positioning mechanism to move is movably mounted above the housing; a reset member that drives the sliding sleeve to move to a first position is disposed within the housing; the housing has a positioning surface that positions the sliding sleeve in a second position; the height of the sliding sleeve in the first position is higher than the height of the sliding sleeve in the second position; the distance between the sliding sleeve and the lower end of the friction seat in the first position is greater than the distance between the sliding sleeve and the lower end of the friction seat in the second position.

[0006] A switching mechanism is provided between the pressing plate and the positioning mechanism; the switching mechanism allows the sliding sleeve to switch between a first position and a second position.

[0007] As a further improvement of this utility model, the switching mechanism is a rebound device; one side of the rebound device is fixedly connected to the pressing plate or the sliding sleeve, and the other side is fixedly connected to the housing.

[0008] As a further improvement of this utility model, the switching mechanism includes a positioning tube fixed in the housing, a sliding column that slides longitudinally in the positioning tube, and a rotating body rotatably connected to the sliding sleeve; the sliding column is fixedly connected to the pressing plate; the positioning surface is uniformly arranged circumferentially on the side wall of the positioning tube; the positioning surface is inclined; a longitudinally distributed sliding groove is provided between two adjacent positioning surfaces; a guide strip is uniformly arranged circumferentially on the rotating body; an inclined guide surface is provided at the upper end of the guide strip; a deflection surface is provided at the lower end of the sliding column that abuts against the guide surface and drives the rotating body to rotate by a set angle; when the guide surface abuts against the positioning surface, the sliding sleeve is in the second position; when the guide surface is in the sliding groove, the sliding sleeve is in the first position.

[0009] As a further improvement of this utility model, the reset component is a reset spring installed inside the housing that drives the sliding sleeve to reset upward.

[0010] As a further improvement of this utility model, a stop is slidably connected inside the housing; the lower end of the stop is provided with a transverse adhesive extending towards the rear side of the housing; when the stop is located at the lower limit position of the housing, the stop is in the installed state.

[0011] As a further improvement of this utility model, the side wall of the abutment is provided with an elastic locking head; the abutment is provided with a button extending to the outside of the housing for driving the elastic locking head to move.

[0012] As a further improvement of this utility model, a limiting frame is fixedly connected to the lower end of the housing; the lower end of the limiting frame is provided with a limiting groove that abuts against the elastic locking head and thus restricts the upward movement of the retaining frame.

[0013] As a further improvement of this utility model, a vertical adhesive backing is fixed to the rear side of the housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation between the sliding sleeve, the friction seat, and the pre-tightening spring, this solution ensures that regardless of whether the ground is uneven, when the sliding sleeve is in the second position, the friction seat will always be pressed against the ground under the thrust of the pre-tightening spring.

[0015] This solution allows users to switch the door between locked and unlocked states simply by repeatedly pressing the button. The operation is simple and quick, avoiding complex procedures and time-consuming processes that could hinder user experience. This significantly reduces the learning curve for users.

[0018] Specific Implementation Example 1: Please refer to Figures 1-6 A gate stop includes a housing 1 and a positioning mechanism disposed within the housing 1. The positioning mechanism includes a sliding sleeve 6 that slides longitudinally within the housing 1, a friction seat 7 that slides longitudinally on the sliding sleeve 6, and a preload spring 92 installed between the sliding sleeve 6 and the friction seat 7. A pressing plate 2 for driving the positioning mechanism is movably mounted above the housing 1. A reset member for driving the sliding sleeve 6 to move to a first position is disposed within the housing 1. The housing 1 has a positioning surface 13 for positioning the sliding sleeve 6 in a second position. The height of the sliding sleeve 6 in the first position is higher than the height of the sliding sleeve in the second position. The distance between the sliding sleeve 6 and the lower end of the friction seat 7 when the sliding sleeve 6 is in the first position is greater than the distance between the sliding sleeve 6 and the lower end of the friction seat 7 when the sliding sleeve 6 is in the second position.

[0019] When the sliding sleeve 6 is in the first position, the lower end of the friction seat 7 is above the ground and does not contact the ground.

[0020] When the sliding sleeve 6 is in the second position, the lower end of the friction seat 7 is in contact with the ground, and the preload spring 92 is contracted.

[0021] A rubber block 71 is fixedly connected to the lower end of the friction seat 7 to increase the friction between the friction seat 7 and the ground.

[0022] A switching mechanism is provided between the pressing plate 2 and the positioning mechanism; the switching mechanism causes the sliding sleeve 6 to switch between a first position and a second position.

[0023] The switching mechanism includes a positioning tube 11 fixed inside the housing 1, a sliding column 4 that slides longitudinally inside the positioning tube 11, and a rotating body 5 rotatably connected to the sliding sleeve 6; the sliding column 4 is fixedly connected to the pressing plate 2; the positioning tube 11 has a positioning surface 13 evenly arranged circumferentially on its side wall; the positioning surface 13 is inclined; a longitudinally distributed sliding groove 14 is provided between two adjacent positioning surfaces 13; a guide bar 51 is evenly arranged circumferentially on the rotating body 5; an inclined guide surface 52 is provided at the upper end of the guide bar 51; a deflection surface 42 is provided at the lower end of the sliding column 4 that abuts against the guide surface and drives the rotating body 5 to rotate by a set angle; when the guide surface 5 abuts against the positioning surface 13, the sliding sleeve 6 is in the second position; when the guide surface 5 is in the sliding groove 14, the sliding sleeve 6 is in the first position.

[0024] The sliding column 4 has a protrusion 41 on its side wall that is slidably connected to the sliding groove 14.

[0025] In the initial state, the guide bar 51 is located within the slide groove 14, and the sliding sleeve 6 is in the first position. At this time, the sliding column 4 moves downward, and the deflecting surface 42 pushes the guide surface 52 to move downward synchronously until the guide surface 52 disengages from the slide groove 14. When the guide surface 52 disengages from the slide groove 14, the guide surface 52 will rotate along the deflecting surface 42 by a set angle, and then the guide surface 52 moves to below the positioning surface 13. At this time, the sliding column 4 slides downward, and the guide surface 52 also moves upward until the guide surface 52 abuts against the positioning surface 13. Then, the guide surface 52 rotates along the positioning surface 13 to one end of the positioning surface 13, at which point the sliding sleeve 6 is in the first position.

[0026] Then the sliding column 4 slides downward again, and the deflecting surface 42 pushes the guide surface 52 downward, causing the guide surface 52 to move downward and separate from the positioning surface 13. At this time, the guide surface 52 will rotate along the deflecting surface 42 by a set angle, and the guide surface 52 rotates to below the slide groove 14. Then the sliding column 4 moves upward, and the guide surface 52 also moves upward and inserts into the slide groove 14, so that the rotating body 5 and the sliding sleeve 6 move to the first position.

[0027] Then, by pressing the sliding column 4, the guide surface 52 switches between the positioning surface 13 and the slide groove 14, and the sliding sleeve 6 cycles between the first position and the second position.

[0028] The reset component is a reset spring 91 installed inside the housing 1 for upward reset of the drive sleeve 6.

[0029] A retainer 3 is slidably connected inside the housing 1; the lower end of the retainer 3 is provided with a transverse adhesive 33 extending toward the rear side of the housing 1; when the retainer 3 is at its lower limit position, the retainer 3 is in the installed state.

[0030] When the support frame 3 is in the installed state, the lower end of the transverse adhesive 33 is higher than the lower end of the friction seat 7 in the second position that is not placed on the ground.

[0031] When installing this device on the door, first adjust the abutment 3 to the installation position, with the sliding sleeve 6 in the first position. Then, press the horizontal adhesive backing 33 against the ground and slide the housing 1 horizontally to attach the vertical adhesive backing to the door. Therefore, after the sliding sleeve 6 is in the second position, the friction seat 7 will press against the ground, and the preload spring 92 will contract, increasing the friction between the friction seat 7 and the ground.

[0032] The side wall of the abutment 3 is provided with an elastic locking head 32; the abutment 3 is provided with a button 31 extending to the outside of the housing 1 for driving the elastic locking head 32 to move.

[0033] The lower end of the housing 1 is fixedly connected to a limiting frame 8; the lower end of the limiting frame 8 is provided with a limiting groove 81 that abuts against the elastic locking head 32 and thus restricts the upward movement of the retaining frame 3.

[0034] The sliding sleeve 6 has a stop block 62 on its side wall; the return spring 91 is disposed between the stop block 62 and the limiting frame 8.

[0035] A vertical adhesive backing 15 is fixed to the rear side of the housing 1.

[0036] Before use, install this device on the door. First, adjust the abutment 3 to the installation position, with the sliding sleeve 6 in the first position. Next, press the horizontal adhesive 33 against the ground and slide the housing 1 horizontally to attach the vertical adhesive to the door. Then, press button 31 to separate the elastic clip 32 from the limiting groove 81, and slide button 31 upwards to attach the horizontal adhesive 33 to the lower end of the door. This completes the installation.

[0037] When the door needs to be positioned in a certain position, rotate the door to the fixed position and step on the pressing plate 2 to make the pressing plate 2 drive the sliding column 4 to move downward. Then, through the cooperation of the rotating body 5 and the positioning tube 11, the sliding sleeve 6 moves from the first position to the second position, and the rubber block 71 presses against the ground.

[0038] Stepping on the press plate 2 again will move the slide 6 from the second position to the first position, allowing the door to move freely.

[0039] Example 2 differs from Example 1 in that the switching mechanism is a rebound device; one side of the rebound device is fixedly connected to the pressing plate 2 or the sliding sleeve 6, and the other side is fixedly connected to the housing 1.
