Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of door stop, specifically discloses a door stop seat of simple and easy adjustment of installation position and door stop including it. BACKGROUND

[0002] The door stop is a fixing device widely applied to various door bodies, which is mainly composed of a door stop head and a door stop seat matched with the door stop head. For example, the door stop disclosed in patent 202211615130.7 is provided with an elastic expansion piece such as a hydraulic oil cylinder or a gas spring on the door stop seat. When the door is closed, the elastic expansion piece can effectively buffer the suction action between the door stop head and the door stop seat, thereby significantly reducing the suction impact force and avoiding damage to the door stop due to instantaneous strong impact. At the same time, the required pulling force can also be reduced when the door is opened, making the door opening process more relaxed, further protecting the door stop, prolonging its service life, and ensuring the normal use of the door body.

[0003] However, the existing door stop also has some deficiencies in actual application. Since the position matching and alignment installation between the door stop head and the door stop seat require high accuracy, if the positions of the two are not accurate during installation, the door body cannot be sucked, resulting in the loss of the function of the door stop in fixing the door. In addition, if the positions of the two are slightly deviated, friction noise is easily generated during the opening and closing of the door, which not only affects the use experience, but also may accelerate the wear of the door stop components. Such high requirements for installation precision make the installation process complex and cumbersome, which is not conducive to the installation personnel to quickly and conveniently complete the installation work, and also limits the application of the door stop in some scenes with high requirements for installation convenience to some extent.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more apparent, understandable and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] A door closer with simple installation position adjustment, referring to Figures 1-8 , comprising a door suction head 1 and a door suction seat 2 cooperating with the door suction head 1, the door suction seat 2 comprising a main body 21 and an elastic expansion piece 22 and a rotating block 23 arranged on the main body 21, the rotating block 23 being hinged with the main body 21, the hinge serving as a rotation shaft between the two, the rotating block 23 having at least a first rotation angle (such as Figure 6 ) of the rotation angle state of the door suction head 1, and a second rotation angle (such as Figure 8 ) of the rotation angle state of the door suction head 1 after being separated and being driven to reset by the elastic expansion piece 22. Specifically, the rotating block 23 is hinged with the main body 21 through a first hinge shaft 24, one end of the elastic expansion piece 22 is hinged with the main body 21 through a second hinge shaft 25, and the other end is hinged with the rotating block 23 through a third hinge shaft 26; in use, the door suction head 1 is engaged or separated with the rotating block 23, which drives the rotating block 23 to rotate around the first hinge shaft 24, and the elastic expansion piece 22 is dragged by the third hinge shaft 26 to rotate around the second hinge shaft 25 and expand or contract.

[0030] The purpose of suction is achieved by setting the swing of the elastic expansion piece 22 and the rotating block 23. In this embodiment, the elastic expansion piece 22 comprises a hydraulic oil cylinder 221 and a spring 222 mounted on the hydraulic oil cylinder 221, one end of the hydraulic oil cylinder 221 is hinged with the main body 21, and the other end is hinged with the rotating block 23, the spring 222 drives the hydraulic oil cylinder 221 to have a spring force to keep the direction of the rotating block 23. The hydraulic oil cylinder 221 of the present scheme provides damping buffer, avoids impact force to form noise, the spring 222 ensures the expansion and contraction of the hydraulic oil cylinder 221, so that the door leaf suction is firm and not easy to be blown open by the wind; when the door is opened, the door suction seat 2 has a buffering effect when hitting the door suction head 1, and is not easy to produce noise, and is not easy to be destroyed by strong wind. Of course, in other embodiments, the elastic expansion piece 22 can also be a gas spring, which can also have a buffering effect.

[0031] In addition, in order to solve the problem of high installation precision requirement of the existing door stop, the door stop body 21 is provided with a mounting seat 3, as shown in Figures 4-5 The mounting seat 3 is provided with a connecting piece 31, a locking piece 32 and a fixing piece 33. The fixing piece 33 is used to fix the mounting seat 3 at the mounting position. The body 21 is provided with a long hole 211 on the side close to the mounting seat 3. The connecting piece 31 is used to limit the disengagement of the body 21 from the mounting seat 3 and allow the relative movement of the two in the direction of the long hole 211. The mounting seat 3 is provided with a locking hole 301 corresponding to the long hole 211. The locking piece 32 penetrates the long hole 211 and is fixed with the locking hole 301, thereby locking the body 21 on the mounting seat 3. By providing the body 21 with the long hole 211, the mounting seat 3 can be first fixed on the door, and then the door stop head 1 is installed on the ground. After that, the locking piece 32 is loosened, and the vertical position of the body 21 on the mounting seat 3 is moved in the direction of the long hole 211. According to the alignment position between the door stop head 1 and the rotating block 23, the locking piece 32 is finally used to lock the body 21 on the mounting seat 3. Therefore, the installation precision can be adjusted and positioned accurately, and the initial installation precision requirement is reduced.

[0032] Specifically, the body 21 of the present scheme is a sheet metal part. The body 21 is provided with a limiting groove 213 for limiting the rotation angle of the rotating block 23, and the third hinge shaft 26 is slidingly arranged in the limiting groove 213. In addition, the body 21 is provided with a first shaft hole 214 for fixing the first hinge shaft 24 and a second shaft hole 215 for fixing the second hinge shaft 25. By adopting the structure of opening the limiting groove 213 to limit the swing amplitude of the rotating block 23, the swing amplitude of the previous door stop which adopts the structure of forming a surface slope profile by casting is replaced. Therefore, the body 21 of the present scheme can be a sheet metal part processed by blanking, bending and hole opening of a metal sheet. Compared with the casting process, the sheet metal part has lower processing cost, simpler assembly structure, lower product production cost, higher strength and better improvement of the structural strength and service life of the door stop.

[0033] In the embodiment, as shown in Figure 4 The fixing piece 33 is a countersunk screw, and the mounting seat 3 is provided with a countersunk hole 302 matched with the countersunk screw. During installation, the mounting seat 3 is first fixed to the door by the countersunk screw, and then the body 21 is installed. By adopting the countersunk screw, the mounting seat 3 and the body 21 can be slidably attached or locked without being blocked, thereby reducing the thickness of the door stop seat. In order to improve the installation stability, the fixing piece 33 can be provided with two or more than two.

[0034] In the embodiment, as shown in Figure 4, the connecting piece 31 is a rivet, the mounting seat 3 is provided with a riveting hole 303, the tail of the rivet is riveted on the riveting hole 303, the head of the rivet is hung on the side of the long hole 211 away from the mounting seat 3, the diameter of the head of the rivet is greater than the width of the minor axis of the long hole 211, so that the purpose of limiting the disengagement of the main body 21 from the mounting seat 3 and allowing the relative movement of the two along the direction of the long hole 211 is realized. The diameter of the rod body of the rivet is preferably just matched with the width of the minor axis of the long hole 211, which can better play a guiding role and prevent the main body 21 from moving vertically on the mounting seat 3 from deviating laterally. In other embodiments, the connecting piece 31 can also be a buckle or other structure that can achieve the above functions, and the standard rivet used in the present embodiment has lower cost and good firmness. For the convenience of users to install, referring to Figure 5 , the main body 21 is provided with a mounting hole 212 for the rivet head to pass through, the mounting hole 212 is communicated with the long hole 211, and when installing, the user can align the rivet head of the mounting seat 3 with the mounting hole 212 and insert it, and then drag the main body 21 to make the rivet head slide to the long hole 211, so that the main body 21 can be hung on the mounting seat 3, and the installation process is convenient and easy. In order to improve the stability of the connection, the connecting piece 31 can be provided with two or more than two.

[0035] In the present embodiment, referring to Figure 4 , the locking piece 32 is a locking screw, and the locking hole 301 has an internal thread matched with the locking screw. After the main body 21 is slid and adjusted to the accurate position on the mounting seat 3, the locking screw is locked with the locking hole 301, so that the main body 21 is clamped between the head of the locking screw and the mounting seat 3, and the relative position of the main body 21 and the mounting seat 3 is locked. When it is necessary to adjust the positions of the two again, the locking screw is loosened, and the main body 21 can be slid and adjusted in the vertical direction, so that the installation precision requirement is reduced, and the adjustment mode is easy and convenient.

[0036] In the present embodiment, referring to Figure 2 , the door stop seat 2 further comprises a main body cover 27 arranged outside the main body 21, the inner side of the main body cover 27 is provided with a buckle, and the side edge of the main body 21 is provided with a clamping groove 216 matched with the buckle. When the mounting seat 3 and the main body 21 are installed and the position adjustment is completed, the main body cover 27 can be buckled and covered on the main body 21, which plays a role in improving the appearance and dustproof property of the door stop seat.

[0037] The principle of the door stop is as follows: Figure 6 The state is the state of the door stop seat 2 and the door stop head 1 being attracted (i.e. the first rotation angle of the rotating block 23), at this time, the force arm of the elastic expansion piece 22 is small, and the spring force is large; Figure 7 When the door leaf is pulled open, the rotating block 23 rotates to the critical point position, at this time, the force arm of the elastic expansion piece 22 is zero, and the spring force is maximum; Figure 8The state is the disengagement state of the door stop seat 2 and the door stop head 1 (i.e. the second rotation angle of the rotating block 23), at which the force arm of the elastic telescopic member 22 is maximum and the spring force is minimum; the door stop and the buffer damping effect are realized through the cooperation of the elastic telescopic member 22 and the rotating block 23. In addition, when the position of the rotating block 23 in the vertical direction needs to be adjusted to better cooperate with the door stop head 1, the locking member 32 is loosened, the vertical position of the main body 21 on the mounting seat 3 is moved along the direction of the long hole 211 until accurate, and finally the locking member 32 is locked on the main body 21 on the mounting seat 3, so that the above-mentioned effect is realized.

[0038] The above-mentioned technical solutions provided by the utility model are described in detail, and the principles and implementation manners of the utility model are described by applying specific examples; the above-mentioned examples are only used for helping to understand the method and the core idea of the utility model; meanwhile, according to the idea of the utility model, the specific implementation manners and application ranges will be changed by the general technical personnel in the field, and according to the above-mentioned description, the content of the specification should not be understood as the limitation of the utility model.
