Description

Technical Field

[0001] The utility model relates to the technical field of door stopper design, in particular to an automatically telescopic door stopper system for hospitals. Background Technique

[0002] A door stopper is a device that fixes the door when it is opened to the maximum position to prevent it from being accidentally blown by the wind or suddenly closed. After the applicant's search, it is found that the most commonly used door stopper in hospitals at present is the "wall-mounted permanent magnet door sucker".

[0003] After the applicant's search, it is found that since the contact between the suction head and the base of the door sucker is rigid, when the door is fixed at the maximum position during opening, the collision sound is relatively large. On the one hand, it affects the work or rest of patients or medical staff in the hospital. On the other hand, it damages the door body and the wall. Secondly, since nurses or doctors often hold trays or report forms and other objects in their hands and can only pull the door handle with one hand, and the adsorption force of the door stopper is relatively strong, it often causes difficulty in separating the door from the door stopper. Some items need to be placed on the table or on the ground. When bending down to operate, because doctors and nurses hold things in their hands, it is also easy for the items to fall and cause damage or infection risks, which is very inconvenient.

[0004] Therefore, in view of this, aiming at the deficiencies of the existing structure for research and improvement, the applicant proposes an automatically telescopic door stopper system for hospitals to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatically telescopic door stopper system for hospitals to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an automatically telescopic door stopper system for hospitals, including a bracket, an installation seat is fixed at the bottom of the bracket, a cylindrical block is fixed on one side of the bracket, a magnetic suction head is installed on one side of the cylindrical block, a telescopic protection cylinder is slidably sleeved outside the cylindrical block, the magnetic suction head is located inside the telescopic protection cylinder, a limiting part is connected between the top of the telescopic protection cylinder and the bracket, and a first return spring is connected between one side of the telescopic protection cylinder and the side wall of the bracket. The limiting part is used to prevent the telescopic protection cylinder from sliding left and right on the cylindrical block.

[0007] Preferably, the limiting part includes a clamping plate rotatably connected to the notch at the top of the bracket, a second return spring is connected between the clamping plate and the bottom surface of the upper end of the bracket, the bottom end of the clamping plate is clamped into the groove at the top of the limiting plate, the limiting plate is fixed at the top of the telescopic protection cylinder, and two grooves are provided on the limiting plate.

[0008] Preferably, the two inner surfaces of the groove are inclined to form a shrinking notch, and one inclined surface inside the groove is attached to the clamping plate, and the clamping plate is in an inclined state at this time.

[0009] Preferably, a limiting rod is fixed to the inner wall of the notch of the mounting clamping plate. The limiting rod is located directly below the clamping plate rotating shaft. When the limiting rod is in contact with the clamping plate, the clamping plate is exactly in contact with one inclined surface of the groove.

[0010] Preferably, a footrest pad is bonded to the surface of the clamping plate, and the footrest pad is made of rubber.

[0011] Preferably, a buffer washer is bonded to the side wall of the telescopic protective cylinder, and the buffer washer is made of silica gel.

[0012] Preferably, a row of sliders is annularly arranged on the inner wall of the telescopic protective cylinder. The sliders slide in the slideways formed on the surface of the cylindrical block, and foam blocks are bonded to both ends of the sliders.

[0013] Preferably, two connecting pieces are fixed to each side of the mounting seat. Bolt holes are provided on the connecting pieces. The mounting seat is provided with an adhesive layer, and a release paper is bonded to the bottom surface of the adhesive layer.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By designing the telescopically elastic telescopic protective cylinder, when the door rotates and approaches the wall during opening, the door first contacts the telescopic protective cylinder. The telescopic protective cylinder slides outside the cylindrical block and compresses the first reset spring. After the telescopic protective cylinder moves backward a short distance, the magnetic sheet on the back of the door will contact the magnetic attraction head to complete adsorption. By using the buffer structure, the problems of easy damage and high noise caused by direct hard contact in the prior art are solved.

[0016] 2. By designing the limiting part, after the door is adsorbed to the magnetic attraction head, the position of the telescopic protective cylinder can be limited, thereby avoiding the telescopic protective cylinder applying a thrust to the door, resulting in adsorption instability and increasing stability. When closing the door, the clamping plate can be gently stepped on with the foot, so that the telescopic protective cylinder loses its limit. Then when closing the door, the telescopic protective cylinder can be reset by the first reset spring, and after losing its limit, it will also apply a thrust to the door, making it easier for the door to separate from the magnetic attraction head, facilitating single-handed and labor-saving operation by doctors and nurses without the need to bend down, which is very suitable for use in hospitals.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] As Figures 1 - 7 shown, an automatically telescopic door stopper system for hospitals includes a bracket 1. A mounting seat 2 is fixed to the bottom of the bracket 1. A cylindrical block 11 is fixed to one side of the bracket 1. A magnetic head 12 is installed on one side of the cylindrical block 11. A telescopic protective cylinder 13 is slidably sleeved outside the cylindrical block 11. The magnetic head 12 is located inside the telescopic protective cylinder 13. A limiting part 3 is connected between the top of the telescopic protective cylinder 13 and the bracket 1. A first return spring 14 is connected between one side of the telescopic protective cylinder 13 and the side wall of the bracket 1. The limiting part 3 is used to prevent the telescopic protective cylinder 13 from sliding left and right on the cylindrical block 11.

[0027] By designing an elastic telescopic protective cylinder 13, during use, the bracket 1 is placed at a suitable position on one side of the wall through the mounting base 2, and a magnetic sheet or magnetic block corresponding to the magnetic head 12 is provided on the back of the door. Then, when the door rotates and approaches the wall when it is opened, the door first contacts the telescopic protective cylinder 13. The telescopic protective cylinder 13 slides outside the cylindrical block 11 and compresses the first return spring 14. After the telescopic protective cylinder 13 moves backward a short distance, the magnetic sheet on the back of the door will contact the magnetic head 12 to complete adsorption. During this process, the first return spring 14 and the telescopic protective cylinder 13 play a certain buffering effect, avoiding direct hard contact between the magnetic head 12 and the door, which may cause damage or excessive noise. The limiting part 3 can position the telescopic protective cylinder 13 when the door is adsorbed to the magnetic head 12, avoiding the instability of the door caused by the thrust of the first return spring 14. It should be noted that the magnetic sheet or magnetic block provided on the back of the door corresponding to the magnetic head 12 is an existing design means.

[0028] As Figures 2 - 4 and Figures 6 - 7 shown, the limiting part 3 includes a clamping plate 33 rotatably connected to the notch at the top of the bracket 1. A second return spring 34 is connected between the clamping plate 33 and the bottom surface of the upper end of the bracket 1. The bottom end of the clamping plate 33 is clamped into the groove 32 at the top of the limiting plate 31. The limiting plate 31 is fixed to the top of the telescopic protective cylinder 13, and two grooves 32 are provided on the limiting plate 31. The two inner surfaces of the groove 32 are inclined to form a retractable notch, and one inclined surface inside the groove 32 is in contact with the clamping plate 33, and the clamping plate 33 is in an inclined state at this time. A limiting rod 36 is fixed to the inner wall of the notch of the bracket 1 where the clamping plate 33 is installed. The limiting rod 36 is located directly below the rotation axis of the clamping plate 33. When the limiting rod 36 is in contact with the clamping plate 33, the clamping plate 33 is exactly in contact with one inclined surface of the groove 32.

[0029] When the door is opened and the telescopic protective tube 13 is displaced, the limit plate 31 moves with it, and the card plate 33 immediately escapes from the first groove of the limit plate 31, and the bottom of the card plate 33 rotates upward and compresses the return spring 2 34. When the magnetic suction head 12 is adsorbed on the magnetic sheet on the back of the door, the card plate 33 just moves to the position of the second groove of the limit plate 31, and under the action of the return spring 2 34, the lower end of the card plate 33 is restored and re-adapted to the groove of the limit plate 31. At this time, the card plate 33 is in an inclined state and fits with the inclined surface of the groove 32, and the lower end of the card plate 33 cannot rotate downward at this time, so that the telescopic protective tube 13 cannot be reset, thereby avoiding the telescopic protective tube 13 from applying a thrust to the door due to the compression of the return spring 14, resulting in an unstable adsorption, thereby increasing stability, and when closing the door, on the one hand, it is necessary to reset the telescopic protective tube 13 to facilitate the next time When the door is opened, the buffer extension is performed. On the other hand, since the doctor or nurse holds items in his hands, it is inconvenient for him to bend over to operate or cannot pull the door handle with both hands, it is necessary to reduce the adsorption force between the magnet on the door and the magnetic suction head 12. At this time, the card plate 33 can be gently stepped on by the foot to rotate its lower end upward, thereby causing the telescopic protective tube 13 to lose the limit. Then, when the door is closed, the telescopic protective tube 13 can be reset by the reset spring 14, and after losing the limit, it will also apply a thrust to the door, thereby making it easier to separate the door from the magnetic suction head 12, which is convenient for doctors and nurses to operate with one hand and save effort, and there is no need to bend over to prevent items from falling, which is very practical. After separation, the foot is removed, and the card plate 33 is again inserted into the first groove of the limit plate 31. At the same time, the limit rod 36 further limits the card plate 33, so that the lower end of the card plate 33 cannot rotate downward. At this time, the card plate 33 can be in the groove, thereby reducing the burden on the rotating shaft of the card plate 33.

[0030] Furthermore, a foot pad 35 is bonded to the surface of the card plate 33 , and the foot pad 35 is made of rubber.

[0031] The foot pad 35 can be used to protect the clamping plate 33 to avoid damage caused by accidentally applying a large force to the clamping plate 33.

[0032] like Figures 4 - 5 As shown, a buffer gasket 15 is bonded to the side wall of the telescopic protective tube 13, and the buffer gasket 15 is made of silicone. A row of sliders 16 are annularly arranged on the inner wall of the telescopic protective tube 13. The sliders 16 slide in the slideways opened on the surface of the cylindrical block 11, and foam blocks are bonded to both ends of the sliders 16.

[0033] By designing the buffer washer 15 and the slider 16, when the buffer washer 15 and the telescopic protective cylinder 13 contact the door, it will contact the door first. At this time, the buffer washer 15 uses its excellent deformation ability and elasticity to perform preliminary buffering, further enhancing the buffering effect. When the telescopic protective cylinder 13 slides outside the cylindrical block 11, a row of sliders 16 will also slide in the corresponding slideways, so that the telescopic protective cylinder 13 will not rotate, further maintaining stability. At the same time, in the design, when in the initial installation or adsorption state, the sliders 16 contact the two ends of the slideway respectively for limiting, and the foam blocks at both ends of the slider 16 can also play a buffering role, which is very practical.

[0034] As Figures 1 - 4 shown, two connecting pieces 21 are fixed on each side of the mounting seat 2. The connecting piece 21 is provided with a bolt hole. The mounting seat 2 is provided with an adhesive layer 22, and a release paper 23 is bonded to the bottom surface of the adhesive layer 22.

[0035] By designing the connecting piece 21, the adhesive layer 22 and the release paper 23, in the assembly, multiple installation methods can be selected. When punching and fixing are required, expansion bolts can be installed through the connecting piece 21 and then fixed to the ground. When bonding is required, the release paper 23 is directly torn off and bonded through the adhesive layer 22, which is very flexible to use. It should be noted that the adhesive layer 22 selects appropriate materials according to different environments or floors, so the detailed structure of the adhesive layer 22 is not limited in this article.

[0036] Working principle: When in use, the bracket 1 is placed at a suitable position on one side of the wall through the mounting seat 2. When the door is opened and rotated and approaches the wall, the door first contacts the telescopic protective cylinder 13. The telescopic protective cylinder 13 slides outside the cylindrical block 11 and compresses the first return spring 14. After the telescopic protective cylinder 13 moves backward a short distance, the magnetic sheet on the back of the door will contact the magnetic head 12 to complete adsorption. During this process, the clamping plate 33 disengages from the first groove of the limiting plate 31, the bottom of the clamping plate 33 rotates upward and compresses the second return spring 34, and at the same time, the clamping plate slides on the surface of the limiting plate 31. When the magnetic head 12 adsorbs the magnetic sheet on the back of the door, the clamping plate 33 just moves to the position of the second groove of the limiting plate 31. Under the action of the second return spring 34, the lower end of the clamping plate 33 is restored and re-clamped in the groove of the limiting plate 31. At this time, the clamping plate 33 is in an inclined state and fits with the inclined surface of the groove 32, resulting in the lower end of the clamping plate 33 being unable to rotate downward, so that the position of the telescopic protective cylinder 13 is fixed. When closing the door, gently step on the clamping plate 33 with your foot to make its lower end rotate upward, and then the telescopic protective cylinder 13 loses its limit. Then when closing the door, the telescopic protective cylinder 13 can be reset through the first return spring 14 for convenient buffering use next time.

[0037] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model so as to design various embodiments with various modifications suitable for specific purposes.
