Description

Technical Field

[0001] This utility model belongs to the field of safety protection and prevention technology for oil depots and gas stations, specifically relating to a semi-intelligent door opener / closer for oil depots and gas stations. Background Technology

[0002] Currently, the doors used in the business offices of oil depots and gas stations are all made of KFC-style thermally broken steel, with a gap of approximately 0.5cm between the door frame and the ground. To facilitate closing, door closers are installed at the top of the door frame, automatically closing after employees or customers push the door open. However, in actual use, this has caused significant inconvenience to employees, customers, and drivers. Each time customers, drivers, or employees enter the oil depot business office to check fuel delivery plans, view fuel density, or print fuel delivery slips, or when gas station customers enter the convenience store to get invoices or purchase goods, they must push and pull the door to enter and exit. To facilitate personnel access, oil depot and gas station operators open the door and then forcibly jam it open by using wooden plugs or metal components between the bottom of the door frame and the ground, preventing it from closing. Prolonged use of this method to keep the door open will cause door frame deformation and damage, and door closer leaks.

[0003] Due to the harsh natural climate conditions in the Hexi Corridor of Gansu, with strong winds and sandstorms in spring and autumn, doors may not close properly during windy or dusty weather due to human negligence. Strong winds can also cause door frame deformation, door closer damage, and glass breakage. In severe cases, the door may separate from the frame, rendering it unusable and requiring a complete replacement. Inquiries with local dealers suggest that repairing a damaged glass door would cost approximately 1200 yuan, replacing a damaged door closer would cost approximately 360 yuan, and replacing the tempered glass would cost approximately 1400 yuan. If the door frame separates from the door, purchasing and installing a new glass door would cost approximately 6000 yuan.

[0004] If the door is deformed, the door frame may rub against the ground when the door is opened and closed, which may generate sparks. Oil depots and gas stations store and sell refined oil products that are flammable, explosive, and volatile. If sparks come into contact with oil and gas, they may cause serious fire or explosion accidents. Utility Model Content

[0005] The purpose of this utility model is to provide a semi-intelligent door opener / closer for oil depots and gas stations, overcoming the aforementioned technical problems in the prior art.

[0006] Therefore, the technical solution provided by this utility model is as follows: A semi-intelligent door opener / closer for oil depots and gas stations includes a protective shell and a climbing shock absorber. The top of the protective shell has a window, and a plate is connected to one side of the window via a pivot. The climbing shock absorber is fixed inside the protective shell and is located directly below the plate. The top of the climbing shock absorber is higher than the window, thus lifting the plate.

[0007] The climbing shock absorber includes a base, a support column, a movable rod, and a top head connected sequentially from bottom to top. A first spring is fitted on the support column, with its lower end connected to the base and its upper end connected to a sliding ring. A hole is opened in the center of the support column, and the lower end of the movable rod is inserted into the hole. A second spring is connected to the lower end of the top head, with its other end connected to the sliding ring. The movable rod is located inside the second spring.

[0008] The protective shell has a cuboid structure, and the cover of the protective shell is detachably connected. The window is located on the cover.

[0009] The card plate is provided with a limiting rod, and the cover is provided with a groove, which is symmetrically arranged on both sides of the window.

[0010] The base has a through hole, and the climbing shock absorber is welded to the protective shell through a connecting rod passing through the through hole.

[0011] The protective shell is made of stainless steel.

[0012] The beneficial effects of this utility model are: This utility model provides a semi-intelligent door opener / closer for oil depots and gas stations, which is embedded in the floor and opens and closes through the cooperation of a locking plate and a climbing shock absorber. When opening the door, the bottom surface of the door contacts the locking plate and presses down on the climbing shock absorber to allow the door to pass smoothly; after the door pushes past the locking plate, the climbing shock absorber automatically pushes the locking plate upward, thereby blocking the door and preventing it from closing, thus keeping the door in a permanently open state.

[0013] This semi-intelligent door opener effectively protects glass doors, preventing damage to the glass door, deformation of the door frame, and breakage of the glass caused by strong winds. It extends the service life of the door, saves a lot of maintenance costs, and also avoids sparks generated by friction with the ground due to deformation, thus preventing safety accidents.

However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to fully and completely disclose the present invention and to fully convey its scope to those skilled in the art. The terminology used in the exemplary embodiments shown in the drawings is not intended to limit the present invention. In the drawings, the same units / elements are referred to by the same reference numerals.

[0018] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning. Example 1

[0019] This utility model provides a semi-intelligent door opener / closer for oil depots and gas stations, including a protective shell 1 and a climbing shock absorber 2. The protective shell 1 has a window on its top, and a clamping plate 3 is connected to one side of the window via a pivot 4. The climbing shock absorber 2 is fixed inside the protective shell 1 and is located directly below the clamping plate 3. The top of the climbing shock absorber 2 is higher than the window, thus lifting the clamping plate 3.

[0020] How to use: The semi-intelligent door opener / closer is embedded in the floor at the door's opening position and secured with concrete. The installation height is flush with the floor tiles. Under the upward force of the climbing shock absorber 2, the card plate 3 remains in the open position for an extended period. Taking the glass door of the gas station's business hall as an example, during the opening process, the bottom of the door pushes and presses the card plate 3, and the card plate 3 presses down on the climbing shock absorber 2, causing the card plate 3 to close as well; after the door pushes past the card plate 3, the climbing shock absorber 2 automatically pops up, lifts the card plate 3, and holds the door in place, keeping the door in a permanently open state, and the door cannot be closed normally.

[0021] To close the glass door, a person needs to press down the latch 3 with their hand or foot, and the door will close automatically, making it easy to operate. Example 2

[0022] Based on Embodiment 1, this utility model provides a semi-intelligent door opener / closer for oil depots and gas stations. The climbing shock absorber 2 includes a base 10, a support column 11, a movable rod 12, and a top 13 connected sequentially from bottom to top. A spring 14 is sleeved on the support column 11. The lower end of the spring 14 is connected to the base 10, and a sliding ring is connected to the upper end of the spring 14. A hole is opened in the center of the support column 11. The lower end of the movable rod 12 is inserted into the hole. A second spring 15 is connected to the lower end of the top 13. The other end of the second spring 15 is connected to the sliding ring, and the movable rod 12 is located inside the second spring 15.

[0023] like Figure 3 As shown, under the pressure of the door, the clamping plate 3 gradually applies pressure to the top 13, compressing the second spring 15, and compressing the first spring 14 downward through the sliding ring until the clamping plate 3 is flattened and flush with the window. At this time, the pressure is at its maximum and the compression of the two springs is at its maximum. After the door gradually passes through the clamping plate 3, the two springs gradually extend and retract until the door is completely away from the clamping plate 3. The two springs extend and retract to their original state, lifting the clamping plate 3, thereby preventing the door from closing. At this point, the door is in an open state. Example 3

[0024] Based on Embodiment 1, this utility model provides a semi-intelligent door opener / closer for oil depots and gas stations, such as... Figure 1 and Figure 2 As shown, the protective shell 1 has a cuboid structure, and the cover 6 of the protective shell 1 is detachably connected, with the window located on the cover 6.

[0025] The cover 6 is detachable and has screw holes 7. It is connected by screws, which facilitates the replacement and maintenance of the door opener / closer. The pivot 4 is used to connect the card plate 3 and the cover 6. The pivot 4 can make the card plate 3 open or close flexibly, with an opening degree of 0.5-1cm. Example 4

[0026] Based on Embodiment 1, this utility model provides a semi-intelligent door opener / closer for oil depots and gas stations, such as... Figure 1 As shown, the card plate 3 is provided with a limiting rod 8, and the cover 6 is provided with a groove 9, which is symmetrically arranged on both sides of the window.

[0027] The limiting rod 8 is used to prevent the card plate 3 from being pressed down and, under the action of gravity, one side of it from entering the protective shell 1, making it inconvenient to use. Example 5

[0028] Based on Embodiment 1, this utility model provides a semi-intelligent door opener / closer for oil depots and gas stations. The base 10 has a through hole, and the climbing shock absorber 2 is welded to the protective shell 1 through a connecting rod 5 passing through the through hole.

[0029] The climbing shock absorber 2 is positioned and fixed inside the protective shell 1 by means of the connecting rod 5. Example 6

[0030] Based on Embodiment 1, this utility model provides a semi-intelligent door opener / closer for oil depots and gas stations, wherein the protective shell 1 is made of stainless steel.

[0031] In this embodiment, the cover 6 is 10cm-2cm in size, the pivot 4 is made of 0.1cm thick stainless steel, which is corrosion resistant, the clamping plate 3 is made of 0.02cm thick stainless steel plate, and the climbing shock absorber 2 is 9cm long and can be opened 10,000 times. The cover 6, clamping plate 3, and pivot 4 are all made of stainless steel and have rust-resistant capabilities.

[0032] This invention improves the utilization rate of glass doors, prevents glass doors from deforming and rubbing against the ground to generate sparks, and provides great protection for the glass doors of oil depots and gas station business rooms, extending their service life and reducing costs.

[0033] Based on on-site usage, after the semi-intelligent door closer was put into use, the door closer automatically rose after the glass door was opened past the top of the closer, effectively locking the door and preventing it from closing automatically. The door was positioned at a 95° effective angle, remaining stationary even in strong winds. To close the door, someone must press down the latch with their hand or foot, which effectively protects the door and extends its lifespan. If the door does not deform, the threshold will not rub against the ground, preventing sparks and effectively eliminating the possibility of accidents.

[0034] The semi-intelligent door closer effectively protects glass doors, preventing damage such as door breakage, frame deformation, and glass breakage caused by strong winds, thus extending the door's lifespan. Before the implementation of this semi-intelligent door closer, the glass doors of oil depots and gas stations required annual inspection and replacement of the door closers and repair of the glass doors. If each oil depot or gas station required repairs twice a year, replacing one set of glass door closers each time, the cost was 360 yuan; repairing the glass door once a year cost 1200 yuan; if the glass door was severely damaged beyond repair, purchasing and installing a new glass door would cost 6000 yuan. Based on 10 oil depots and gas stations, the surplus cost would be approximately 7200-60000 yuan.

[0035] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
