Description

Technical Field

[0001] This utility model relates to the field of door catch technology, specifically a two-stage adjustable card-type floor catch. Background Technology

[0002] A doorstop, also known as a door catch, is a positioning device that holds an open door in place to prevent it from being blown away by wind or collided with, causing it to rotate or close. Common doorstop products generally consist of two parts: a base and a nozzle. In use, the base is fixed to a wall or floor, and the nozzle, installed behind the door, works in conjunction to secure the door. Doorstops can be categorized by installation method into wall-mounted and floor-mounted types. Floor-mounted doorstops are essentially the same as wall-mounted doorstops. Most existing floor-mounted doorstops use magnets to hold the door, but over time, this magnetism can demagnetize, weakening the suction. Utility Model Content

[0003] The purpose of this invention is to provide a two-stage adjustable card-type floor suction cup to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a two-section adjustable snap-on floor suction cup, comprising a fixed unit and a movable unit. The fixed unit is used for fixed installation with the floor, and the movable unit is used for fixed installation on the lower back of the door. The fixed unit includes a disc-shaped mounting base, in which a tongue plate a is hinged. When the movable unit approaches the fixed unit, the tongue plate a is magnetically attracted and popped up. A locking protrusion a is provided on the inner side of the front end of the tongue plate a. The movable unit includes an outer shell with an open front side. An inner shell is inserted into the outer shell from the bottom. A protruding tongue plate b is hinged in the inner shell. The tongue plate b is L-shaped and extends from the front of the inner shell. Two locking protrusions b are provided at the front end of the tongue plate b. A screw is screwed into the inner shell. The lower end of the screw is used to abut against the tail end of the tongue plate b. The tongue plate a and the tongue plate b are snapped together.

[0005] Preferably, the tongue plate a has a rectangular groove in the middle, and the tongue plate a is flipped downward and embedded in the rectangular groove. The mounting base and the outer shell are both provided with mounting holes.

[0006] Preferably, a hand-tightening nut is fixedly installed on the screw, and a through hole is provided on the back of the inner housing, with the rear side of the hand-tightening nut extending out from the through hole.

[0007] Compared with the prior art, the beneficial effects of this utility model are: after the door is opened, tongue plate a and tongue plate b are superimposed and locked together, the locking is firm and has two adjustable connection strength positions to meet different usage needs.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Please see Figure 1-4 This utility model provides a technical solution: a two-section adjustable card-type floor suction cup, including a fixed unit 1 and a movable unit 2. The fixed unit 1 is used for fixed installation with the floor, and the movable unit 2 is used for fixed installation on the lower back of the door. The fixed unit 1 includes a disc-shaped mounting base 101, in which a tongue plate a102 is hinged. A rectangular groove is provided in the middle of the tongue plate a102. The tongue plate a102 is flipped downward and embedded in the rectangular groove. When the movable unit 2 approaches the fixed unit 1, the tongue plate a102 (made of iron) is magnetically attracted and popped up. A locking protrusion a103 is provided on the inner side of the front end of the tongue plate a102.

[0015] The active unit 2 includes an outer shell 201 with an open front side. Both the mounting base 101 and the outer shell 201 are provided with mounting holes. An inner shell 202 is inserted into the outer shell 201 from the bottom. A protruding tongue plate b203 is hinged in the inner shell 202. The tongue plate b203 is L-shaped and protrudes from the front of the inner shell 202. The tongue plate b203 can undergo a certain amount of elastic deformation. Two locking protrusions b206 are provided at the front end of the tongue plate b203. A screw rod 204 is screwed into the inner shell 202. A hand-tightening nut 205 is fixedly installed on the screw rod 204. A through hole is provided on the back of the inner shell 202. The rear side of the hand-tightening nut 205 protrudes from the through hole. The lower end of the screw rod 204 is used to abut against the tail end of the tongue plate b203. Rotating the hand-tightening nut 205 can adjust the tightness of the screw rod 204 against the tongue plate b203. Tongue plate a102 and tongue plate b203 are engaged. Since tongue plate b203 has two locking protrusions b206, two locking positions are formed between tongue plate a102 and tongue plate b203. Moreover, the locking strength of the two locking positions is different, thereby achieving two-stage adjustment. The outer plastic layer of tongue plate b203 reduces noise during engagement.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
