Description

Clamping door stopper

Technical Field

The invention relates to a door stopper capable of positioning a door leaf in an open state, in particular to a clamping type door stopper.

Background

A door leaf in an open position, if not positioned effectively, is very susceptible to being closed by wind or accidental impacts and violently striking the door frame, causing damage to the frame and to the door leaf. In order to solve the above problems, people usually install door stoppers, also called door stoppers, on the door leaf and the corresponding wall or ground. According to different structures, the door stopper can be generally divided into a magnetic type door stopper and a clamping type door stopper. The clamping type door stopper is used for clamping an insertion body which is arranged in a matched manner through a clamping device to complete the positioning of a door leaf. For example, the bullet-shaped door stopper in the chinese utility model 99212118.3 comprises a plug and a holder, wherein the plug comprises a fixing base (1), a bullet-shaped insert buckle (3) and a connecting rod (2) connected between the fixing base (1) and the bullet-shaped insert buckle (3). The clamping seat is composed of a fixed seat (5) and a clamping jaw (4) arranged on the fixed seat (5). One end of the clamping jaw (4) is positioned in the fixed seat (5) and is spread by the compression spring (6), and the other end of the clamping jaw extends out of the fixed seat (5). The inner cavity of the clamping jaw (4) corresponds to and is larger than the inserting buckle (3), a guide angle which is about a 45-degree angle is arranged at the inserting hole (8) of the clamping jaw (4), so that the bullet-shaped inserting buckle (3) is not easy to damage, and the inserting resistance is smaller.

Disclosure of Invention

Analysis of the bullet-shaped door stopper in the above patent 99212118.3 shows that, because one end of the clamping jaw (4) extends into the fixing seat and the other end extends out of the fixing seat (5), the waist of the clamping jaw (4) is clamped in the narrowed through hole at the top of the fixing seat (5) and is suspended on the fixing seat (5). In this way, the clamping jaws (4) can obviously shake during opening and closing due to lack of guide support, so that the clamping jaws can not clamp the bullet-shaped inserting buckle (3) due to bias during closing. In addition, the exposed clamping jaws (4) are very easy to be damaged by collision of foreign objects. After long-term use, after the clamping jaw (4) is impacted by the bullet-shaped inserting buckle (3) for multiple times, the waist part of the clamping jaw (4) is possibly separated from the narrowed through hole at the top of the fixed seat (5) and sinks into the fixed seat (5), so that the clamping jaw (4) cannot be freely opened and closed. Secondly, it can be found that the clamping jaws (4) need to be clamped in the narrowing through holes at the tops of the fixing seats (5) one by one during assembly, but the narrowing through holes are small, so that the clamping jaws (4) are very difficult to install and then the other clamping jaw (4) is installed. Then, it is more difficult to install the compression spring (6) on the pair of clamping jaws (4) by extending the handle into the narrow inner cavity of the fixed seat (5).

In view of the above, the invention provides a clamping door stopper adopting a brand new structure, which comprises a door sucker and a door sucker rod, wherein the door sucker rod comprises a combining head for combining the door sucker; the door sucker is characterized by comprising a disk shell with an accommodating cavity and a bottom plate combined at the lower end of the disk shell, wherein the bottom plate and the disk shell are of a split structure, a top through hole for allowing the combination head to pass through is formed in the top wall of a shell of the disk shell, at least two sliders capable of sliding in the radial direction are arranged in the accommodating cavity, and a radial guide device for providing radial sliding guide for the sliders is arranged on the top wall of the shell of the disk shell or between the bottom plate and the sliders; the slider is provided with a slider top wall facing the shell top wall of the disk shell, a slider bottom wall facing the bottom plate, and a front clamping working face wall and a slider rear end wall which are connected between the slider top wall and the slider bottom wall and are arranged front and back, an elastic driving element used for driving the slider to move in a telescopic mode is arranged between the slider rear end wall and the cavity side wall of the accommodating cavity, a clamping opening is formed between the front clamping working face walls of the at least two sliders, the at least two sliders are used for clamping a combination head which penetrates through the top through hole and enters the accommodating cavity when the at least two sliders are in a contraction state, and the combination head can be opened and released when the combination head is pulled away.

The bottom plate is combined with the lower end position of the disc shell, and the bottom plate can be accommodated in the accommodating cavity of the disc shell and positioned at the lower position of the accommodating cavity or arranged outside the accommodating cavity of the disc shell and covered on the cavity opening of the accommodating cavity.

Wherein, a split structure is arranged between the bottom plate and the disc shell. Thus, when the bottom plate and the disk housing are in a separated state, the accommodating cavity of the disk housing is exposed to facilitate direct observation of the components and structures disposed therein, so that the slider and the elastic driving element can be visually assembled into the accommodating cavity.

Wherein a radial guide device for providing a radial sliding guide for the slider is provided between the case top wall or the bottom plate of the disk case and the slider. The above feature defines the layout position of the radial guide, which may be provided between the case top wall of the disk case and the slider, or between the base plate and the slider. Under the guidance of the radial guide device, the slide blocks have relatively constant radial movement paths, so that the slide is more stable, obvious left-right offset in the sliding process is reduced, and the at least two slide blocks can be basically accurately abutted to clamp the combination head.

The slider has a slider top wall facing the case top wall of the disk case, a slider bottom wall facing the base plate, and a front clamping face wall and a slider rear end wall joined between the slider top wall and the slider bottom wall and spaced forward and rearward. The above features define that when the slider is assembled into the receiving cavity, the front clamping face wall and the slider rear end wall are also integrally disposed within the receiving cavity between the housing top wall and the base plate. That is, the slider is also integrally stored in the storage cavity.

The radial direction is a direction perpendicular to a direction in which the coupling head is inserted into the receiving cavity.

According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: firstly, because the bottom plate and the disk shell are of a split structure, the slider and the elastic driving element can be assembled in the accommodating cavity in a visible state and in a relatively large operating space after the bottom plate and the disk shell are disassembled, and the assembly operation is very convenient. Secondly, because the whole sliding block is collected in the containing cavity, the sliding block cannot be damaged by collision of foreign objects to weaken the clamping of the combining head. And under the guiding action of the radial guide device, the slide block is more stable and less prone to have offset in the moving process so as to influence the clamping of the combination head. Furthermore, since the elastic driving element for driving the slider to move in an extending and contracting manner is provided between the rear end wall of the slider and the cavity side wall of the housing cavity, the cavity side wall of the housing cavity is a structure having a relatively constant structure, and the elastic driving element can be relatively constantly supported by pressing, so that the slider can maintain an effective clamping force for a long time.

the ribs and grooves may be selectively disposed on the top wall of the case and the top wall of the slider of the disk case. In particular, it can be interpreted that, when the rib is provided on the top wall of the case of the disk case, the groove is provided on the top wall of the slider; or the ribs and the grooves can be interchanged, that is, when the grooves are arranged on the top wall of the shell of the disk shell, the ribs are arranged on the top wall of the sliding block. In addition, the ribs and the grooves can be selectively arranged on the bottom plate and the bottom wall of the sliding block respectively, and have meanings similar to those of the above description, and repeated description is omitted.

The further technical scheme can also be that a cushion pad is arranged on the inner side of the bottom plate in the containing cavity, and the cushion pad is positioned on the bottom plate and arranged corresponding to the clamping opening. Thus, when the combination head passes through the top through hole, enters the containing cavity and impacts the cushion pad, the cushion pad can reduce the impact force of the combination head and reduce the generation of noise.

In order to facilitate the positioning of the cushion pad, a further technical scheme can also be that a concave cavity is further arranged on the bottom plate, and the cushion pad is embedded in the concave cavity. Thus, the buffer pad is positioned on the bottom plate by being embedded in the concave cavity, and the buffer pad and the bottom plate are initially assembled into a module, so that the buffer pad and the plate shell can be further assembled at a later stage conveniently. In addition, when the thickness of the buffer pad is properly controlled to be smaller than the depth of the concave cavity, the buffer pad is integrally embedded into the concave cavity, and the influence on the sliding of the sliding block is reduced.

As for the connection between the disk housing and the bottom plate, a further technical solution that can be adopted is that a connecting column arranged in the accommodating cavity is provided on the top wall of the housing of the disk housing, a plate through hole arranged corresponding to the connecting column is provided on the bottom plate, and a fastener is connected to the connecting column through the plate through hole.
