Detailed Description

For better understanding of the purpose, structure and function of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 and 2 show the structure of a door clamp according to an embodiment of the present invention. As shown in fig. 1 and 2, the door clip includes: the door frame assembly comprises a zenith shaft assembly 1 and an upper clamp 2, wherein the zenith shaft assembly 1 is fixedly installed on the top of a door frame 10, the upper clamp 2 is fixedly installed on the top edge of a door 20, the zenith shaft assembly 1 comprises an installation plate 12 and a shaft 11, the installation plate 12 is fixedly installed on the top of the door frame 10, the shaft 11 is fixedly connected with the installation plate 12, and a shaft hole 21 matched with the shaft 11 is formed in the upper clamp 2. Wherein the shaft 11 is drawn and defined within the shaft hole 21.

The utility model discloses in the door presss from both sides, inject in shaft hole 21 through drawing axle 11, press from both sides the installation as the door and lack the norm, the gap that leads to between the topside of door 20 and the top of door frame 10 is too big, perhaps when taking place the tenesmus in the long-time use of door 20, axle 11 can not throw off shaft hole 21 all the time to avoided door 20 whole to empty and take place to hinder the people accident. The utility model discloses door clamp simple structure, it is safe in utilization economy, and simple to operate is favorable to extensively promoting and using.

According to the utility model discloses, the mode that axle 11 was drawn and is injectd in axle hole 21 can have the multiple.

In a preferred embodiment, as shown in fig. 2, the shaft 11 may be defined within the shaft bore 21 by at least one cord 4. Because the rope body 4 has certain flexibility, the rotation of the shaft 11 in the shaft hole 21 cannot be influenced when the rope body is used, and therefore, the rotation of the upper clamp 2 relative to the zenith axis assembly 1 cannot be influenced, and the opening and closing of the door 20 cannot be influenced. In addition, the rope body 4 is more economical to use, and the production cost is saved.

Preferably, according to actual needs, the shaft 11 may be limited in the shaft hole 21 by a plurality of ropes 4 without affecting the normal rotation of the shaft 11 relative to the shaft hole 21, so as to ensure that the shaft 11 is more stably limited in the shaft hole 21, thereby further effectively preventing the falling of the door 20 as a whole due to the shaft 11 falling out of the shaft hole 21. Also preferably, the rope body 4 can be selected to be the most economical and practical steel wire rope.

Of course, the shaft 11 may be defined in the shaft hole 21 by using the string 4 in various ways. Preferably, as shown in fig. 2, one end of the rope 4 can pass through the shaft 11 and be fixed with the shaft 11, and the other end can pass through the shaft hole 21 and be fixedly connected with the side wall of the upper clamp 2. Also preferably, the rope body 4 may be sequentially passed through the shaft 11 and the shaft hole 21 and then connected end to end.

In another preferred embodiment, the shaft 11 may be defined within the shaft bore 21 by a retaining structure.

Specifically, as shown in fig. 3, the stopper structure may be configured to include an outer annular projection 111 formed on an outer circumferential wall of the bottom of the shaft 11 and an inner annular projection 211 formed on an inner circumferential wall of the top end of the shaft hole 21, wherein an outer diameter dimension of the outer annular projection 111 is equal to an inner diameter dimension of the shaft hole 21, and an inner diameter dimension of the inner annular projection 211 is equal to or greater than the outer diameter dimension of the shaft 11 and smaller than the inner diameter dimension of the shaft hole 21. Preferably, the inner annular boss 211 has an inner diameter dimension equal to the outer diameter dimension of the shaft 11. When the shaft 11 is installed in the shaft hole 21, the top of the shaft 11 is first passed through the shaft hole 21 from below and then the top of the shaft 11 is fixed to the mounting plate 12. The limiting structure can realize free rotation and up-and-down movement of the shaft 11 in the shaft hole 21 and prevent the shaft 11 from completely falling out of the shaft hole 21.

As shown in fig. 1, the door clip according to the embodiment of the present invention may further include a bottom clip 3 for being mounted on the bottom edge of the door 20, and the bottom clip 3 is rotatably connected to a ground spring 5 mounted below the ground plane. Under the combined action of the head-piece assembly 1, the upper clamp 2 and the bottom clamp 3, the door 20 can be smoothly opened and closed relative to the doorframe 10.

Furthermore, the utility model also provides a door 20, it includes above-mentioned door clamp. Because above-mentioned door clamp has avoided door 20 whole to take place to empty effectively, consequently the utility model discloses door 20 is safer when using.

Preferably, the door 20 of the embodiment of the present invention may be preferably a glass door, and the safety of the door clamp itself may effectively avoid the greater danger caused by the glass door breaking after falling.
