Problems solved by technology

[0005] Although the door support provided by the Chinese patent CN2202783 to prevent the door from closing belongs to a special door stop device, it is small in size and is located at the lower part of the door body, which does not affect the visual perception as a whole, but the whole door support needs to be fixed on the door body by screws , this will damage the door body, and screws and other installation components are required before use, which will be more cumbersome when disassembling

Embodiment 1

[0026] like figure 1 As shown, the door body positioner of the present invention includes a base plate 9 and an elastic rod.

[0027] The elastic rod is made of beryllium bronze. Because beryllium bronze has good elasticity, after solution treatment and aging heat treatment, the tensile strength can reach 1250~1500MPa. Both the elastic force stability and dimensional stability are better than spring steel. Bottom plate 9 can be solid wood plate shape, also can be convoluted or perforated plate shape. The length of base plate 9 should be 3~5 times of elastic bar length.

[0028] The elastic rod includes a first end 6, a middle part 2 and a second end 3 connected in sequence from back to front. The first end 6 is fixed to the rear end of the bottom plate 9 by bolts 1, and the middle part 2 of the elastic rod is inclined forward and upward. into a certain elevation angle.

[0029] The elevation angle is preferably 15-30 degrees. Of course, it should be determined according to...

Embodiment 2

[0034] like figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the middle part 2 of the elastic rod is provided with a concave bayonet 21, and the size of the bayonet 21 is consistent with the width of the lower end of the door body, which is convenient for the door body to be snapped into place. There are 21 bayonet ports. And the front end of the second end portion 3 of the elastic rod is provided with a transverse direction (that is, perpendicular to figure 2 As shown in the plane) strut, the front end of the second end portion 3 is inserted into the transverse strut 31 . This embodiment is suitable for the state where the door body is half-closed. The entire door body locator should be placed between the door body and the door frame, and the transverse strut 31 is inserted into the door gap, that is, the joint position between the door body and the door frame.

Embodiment 3

[0036] like image 3 As shown, the difference between this embodiment and Embodiment 1 is that the front end of the second end 3 of the elastic rod is provided with a transverse direction (that is, perpendicular to image 3 shown in the plane) strut, the front end of the second end 3 is inserted into the transverse strut 31; and the front end of the bottom plate 9 is inclined upward to form a certain elevation angle (7-15 degrees), and a Group spacer 91, the height of each spacer 91 is inconsistent, and the height value of spacer 91 closer to the front end of base plate 9 is larger, and the thickness of base plate 9 is consistent; In order to strengthen the stability of the whole door body locator, add a bolt 1 for The first end 6 of the elastic rod is fixed.

Abstract

The invention discloses a device for stopping the closing of a door body and particularly relates to a positioning device for positioning a sliding door. The door body positioning device comprises a bottom plate and an elastic rod, wherein the elastic rod comprises a first end part, a middle part and a second end part which are connected in sequence from back to front; the first end part is fixed at the rear end of the bottom plate by a bolt; the middle part of the elastic rod is inclined frontwards and upwards to form a certain elevation; the bolt comprises a bolt head and a thread column; the thread column is in thread connection with the bottom plate; a spring gasket, a compression spring and a flat gasket, which sleeve the thread column in sequence, are arranged between the bolt head and the bottom plate in sequence; the first end part is clamped between the spring gasket and the compression spring; and the second end part is in an arc shape which is bent downwards. Aiming at overcoming the defects that the door body is damaged and is inconvenient to detach in the prior art, the invention provides the door body positioning device which can be used for enhancing the ground friction relative to the door body by elastic pressing.

Description

technical field [0001] The invention relates to a device for preventing the closing of a door body, in particular to a positioner for positioning a sliding door. Background technique [0002] The sliding doors of building houses often need to be opened for a long time to ventilate, or to open the door for a period of time for the convenience of people entering and exiting and carrying items. Usually people's way is to block with the heavy object that can prevent the door from being closed, pulls with rope, pushes or pulls with hand, leans against with the body and other temporary measures, which is very inconvenient. During ventilation, the door is often closed due to wind blowing, and at the same time, it emits a strong collision sound with the door frame, which affects people's work and rest in a quiet environment, resulting in damage to the door and door frame, cracks between the door frame and the wall, and the surrounding wall peeling off. [0003] Existing solutions i...
