Description
Technical Field
[0001] The utility model relates to the technical field of door lock handles, in particular to a three-in-one split door lock handle square cover structure. Background Art
[0002] Traditional door handle (handle round cover adopts two-piece design). The handle round cover has a smaller middle hole because it covers a circle of screw heads on the handle base. This two-piece design of the handle round cover cannot make the middle hole of the handle round cover larger due to the standard lock core (hole distance 38mm) on the market. This will result in the handle round cover being unable to pass through the right angles of various shapes of handles (resulting in limited innovation in handle shapes).
[0003] At the same time, the traditional door handle (the handle cover adopts a two-piece design). This two-piece design of the handle cover will cause the handle cover to be inserted into the handle foot before the handle is installed (the reason: it cannot pass through the right angle of the handle, and needs to be inserted into the handle foot from the root of the handle in advance). Because the handle cover stays at the handle foot, it will be inconvenient to use a screwdriver to tighten the screw (in serious cases, the screwdriver may not be inserted). Utility Model Content
[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.
[0005] To this end, one purpose of the present invention is to propose a three-in-one split door lock handle square cover structure to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.
[0006] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a three-in-one split door lock handle square cover structure, comprising a right-angle handle, a handle square sheet, and a handle bottom sheet, wherein the root of the right-angle handle is movably connected to the handle square sheet, and positioning holes are opened at the four corners of the handle square sheet;
[0007] A sleeve is fixedly connected to the back of the handle bottom plate, a countersunk screw is threadedly connected in the sleeve, and the handle bottom plates are connected via the sleeve and the countersunk screw;
[0008] A square steel is installed at the root of the right-angle handle, a square handle sheet is installed on the front of the handle bottom sheet, a square handle cover is pressed on the front of the handle bottom sheet, the square handle cover is covered on the square handle sheet, and a circular opening is provided in the middle of the square handle cover;
[0009] The root of the right-angle handle is threadedly connected with a set screw, and the end of the set screw is inserted into the square steel.
[0010] Preferably, any of the above schemes is that the right-angle handle and the handle square plate are pre-assembled structures, and wood screws can be inserted into the positioning holes.
[0011] Adopting the above technical solution: The handle cover of the door handle adopts a three-piece design, which consists of a handle square piece, a handle bottom piece and a handle square cover. This three-piece design will not be unable to enlarge the middle hole of the handle square cover due to the standard lock core (hole distance 38mm) on the market. The handle square cover is not used to cover the screws on the handle bottom piece, and the handle square piece is used to cover the screws, so that the middle hole of the handle square cover can be made large enough.
[0012] In this way, the handle square cover can pass through the right-angle positions of handles of various shapes (the shape of the handle is effectively innovated).
[0013] Preferably, any of the above schemes comprises, from the root to the inside, a handle bottom sheet, a handle square sheet and a handle square cover.
[0014] First of all, when installing a door handle, you need to distinguish between inside and outside the door (to prevent theft). The screw heads of the door handle installed inside the door are installed inward. The traditional handle base plate requires the installer to distinguish (the two screw heads face the same direction, the one with threaded holes is installed outside the door, and the one with countersunk holes is installed inside the door), which will lead to the probability of human error. The locking method of the retracted screws in the three-piece design of the door handle is optimized (the two screw heads are in opposite directions). In this way, the installer does not need to distinguish the installation position of the handle base plate, which facilitates installation and prevents errors.
[0015] Preferably, any of the above schemes is that a vortex spring is installed between the handle square plate and the handle bottom plate, and the vortex spring is sleeved on the outer surface of the square steel.
[0016] The spiral spring is used to provide the torque when rotating the handle, and to reset the handle when the handle is released.
[0017] Preferably, any of the above schemes is that the handle square sheet covers the screws on the handle base sheet, and the handle square cover covers the screws on the handle square sheet.
[0018] The handle cover adopts a three-piece design, so the countersunk screws are installed first to connect the handle base, and then the right-angle handle and the square handle are installed, and finally the square handle cover is installed. Since the square handle cover can pass through the foot of the right-angle handle, the square handle cover can be installed last without affecting or interfering with the tightening operation of the countersunk screws.
[0019] Compared with the prior art, the advantages and beneficial effects of the utility model are:
[0020] 1. The handle square cover structure of the three-in-one split door lock adopts a three-piece design through the coordination of the handle square piece, handle base, sleeve, countersunk screw, and handle square cover. The handle cover of the door handle adopts a three-piece design, which is composed of the handle square piece, handle base and handle square cover. This three-piece design will not be unable to enlarge the middle hole of the handle square cover due to the standard lock core (hole distance mm) on the market. The handle square cover is not used to cover the screws on the handle base, and the handle square piece is used to cover the screws, so that the middle hole of the handle square cover can be made large enough.
[0021] In this way, the handle square cover can pass through the right-angle positions of handles of various shapes (the shape of the handle is effectively innovated).
[0022] 2. The three-in-one split door lock handle square cover structure adopts a three-piece design. Therefore, the countersunk screws are installed first to achieve the connection of the handle base plate, and then the right-angle handle and the handle square plate are installed, and finally the handle square cover is installed. Since the handle square cover can pass through the foot of the right-angle handle, the handle square cover can be installed last without affecting or interfering with the tightening operation of the countersunk screws.
