Description

Technical Field

[0001] The utility model relates to the field of door components, in particular to a door handle with protective and anti-collision functions. Background Art

[0002] Door handles are an important part installed on doors. They are mainly used to facilitate the opening and closing of doors, and they also have a certain decorative effect. In modern architecture, glass doors are widely used in commercial spaces, offices and home environments due to their transparent and light characteristics, creating a sense of modernity and openness. Therefore, the combination of door handles and glass doors has become a trend in modern design, but glass is relatively fragile. When a user accidentally hits the door handle, the glass door panel is easily broken due to the impact force transmitted from the door handle, which can easily cause safety hazards. Utility Model Content

[0003] In order to overcome the problem that the glass is fragile and can break when the user accidentally hits the door handle, the glass door panel may be easily broken by the impact force transmitted from the door handle, thus posing a safety hazard.

After the bolt on the front pad is passed through the door panel, the first plug hole on the rear pad is connected to the bolt from the other side of the door panel, and the nut is tightened on the bolt to fix the front pad and the rear pad on the door panel.

[0007] Preferably, four bolts are fixedly connected to the rear end surface of the front pad; nuts are loosely fitted at the ends of the bolts; and four first insertion holes are provided on the front end surface of the rear pad.

[0008] Preferably, a hollow soft pad is fixedly connected in each of the first installation grooves, and non-Newtonian fluid is filled in the hollow soft pad; four second jacks are formed in each of the hollow soft pads; a plurality of soft connection columns are arranged in the hollow soft pads, and the soft connection columns and the hollow soft pads are integrally formed. Due to the fluidity of the non-Newtonian fluid, the hollow soft pads can be seamlessly attached to the door panel, the front backing plate and the rear backing plate. When the door handle is impacted, the non-Newtonian fluid quickly hardens to evenly transmit and distribute the impact force on the door panel.

[0009] Preferably, the fixing assembly includes a positioning cover, screws, a first groove, a chamfer, and a second installation groove; positioning covers are arranged at the front end of the front backing plate and the rear end of the rear backing plate; six screws are in clearance fit with the positioning covers, and the screws are also in clearance fit with the front backing plate and the rear backing plate at the same time.

[0010] Preferably, a first groove is formed at one end of each of the positioning covers; a chamfer is formed at the edge of the first groove; a second installation groove is formed at the other end of the positioning covers.

[0011] Preferably, the force unloading assembly includes an inner backing plate, a handle, a fourth installation groove, and a shock absorber; the inner backing plate is slidably connected in the positioning cover; a handle is fixedly connected to one end of the inner backing plate; four fourth installation grooves are formed at the other end of the inner backing plate; shock absorbers are fixedly connected in the fourth installation grooves.

In this process, the shock absorber can be used for buffering to reduce the impact of the door handle on the door panel, and the injury of the person hitting the door handle can also be reduced. The first groove and the chamfer can prevent the handle from pinching the user's hand during the retraction process.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. By providing a contraction buffering mechanism and a uniform force dispersion mechanism, the door handle contracts when impacted, so as to reduce the injury of the user caused by the impact while buffering, and the weakened impact force is evenly dispersed to a larger area of the glass door panel to reduce the probability of the glass door panel being broken due to the impact on the door handle;

[0014] 2. When the door handle is impacted, the inner backing plate and the handle retract into the positioning cover together. In this process, the shock absorber can be used for buffering to reduce the impact of the door handle on the door panel, and the injury of the person hitting the door handle can also be reduced. The first groove and the chamfer can prevent the handle from pinching the user's hand during the retraction process, so as to reduce the probability of the glass door panel being broken due to the impact on the door handle while reducing the injury of the user caused by the impact.

[0015] 3. The flowability of the non-Newtonian fluid enables the hollow soft pad to fit seamlessly with the door panel, the front backing plate, and the rear backing plate. When the doorknob is impacted, the non-Newtonian fluid quickly hardens, causing the impact force to be evenly transmitted and distributed on the door panel, thereby further reducing the probability of the glass door panel breaking due to the impact on the doorknob.

[0028] When the door handle is hit, the inner backing plate 301 and the handle 302 retract into the positioning cover 201 together. In this process, the shock absorber 304 can be used for buffering to reduce the impact of the door handle on the door panel, and the injury of the person hitting the door handle can also be reduced. The first groove 203 and the chamfer 204 can prevent the handle 302 from pinching the user's hand during the retraction process, thereby reducing the probability of the glass door panel breaking due to the impact on the door handle while reducing the injury of the user due to the impact. The non-Newtonian fluid will also quickly harden to evenly transfer and distribute the impact force on a large area of the door panel, thereby further reducing the probability of the glass door panel breaking due to the impact on the door handle.

[0029] Through the above steps, a contraction buffer mechanism and a uniform force dispersion mechanism are set up, so that the door handle contracts when hit, to reduce the injury of the user due to the impact while buffering, and to evenly disperse the weakened impact force to a larger area of the glass door panel to reduce the probability of the glass door panel breaking due to the impact on the door handle.
