Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lockset, concretely relates to a steering mechanism and a lockset. BACKGROUND

[0002] For the locking mechanism of a door, a conventional design usually comprises one locking point (hereinafter referred to as a conventional locking point) or a row of locking points (usually a plurality of locking points distributed along the vertical direction at intervals), and a lockset (single or multiple) is arranged to lock each locking point. This design not only meets the basic safety requirements, but also ensures the simplicity of the structure and the convenience of the operation.

[0003] At present, some doors are additionally provided with extra locking points (such as a plurality of extra locking points distributed along the horizontal direction at the top or bottom of the door). Taking the plurality of extra locking points as an example, the arrangement of these extra locking points is different from that of the conventional locking points. For example, when the conventional locking points are distributed along the vertical direction, the extra locking points are distributed along the horizontal direction, aiming to better realize the locking of the door by increasing the number of locking points and expanding the distribution range of the locking points. Although this design improves flexibility to some extent, it also brings the following problems:

[0004] 1. Increased structural complexity. The addition of extra locking points means that additional lockset components and other structures and installation space are needed, increasing the manufacturing cost of the door. At the same time, the complex structure may increase the difficulty of installation and maintenance.

[0005] 2. Decreased operational convenience. Taking a single conventional locking point and a single extra locking point as an example, the two locking points are used independently, so both need to be operated independently. Specifically, two locksets need to be used and the specific locking structures (such as flat rods) in the two locksets need to be moved in different directions (such as the horizontal and vertical directions) to switch the locking of the two locking points.

[0006] Therefore, how to solve the problems of increased structural complexity and decreased operational convenience caused by the addition of extra locking points in the prior art has become a research topic of the utility model. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims to provide a steering mechanism and a lockset.

[0008] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of:

[0009] The steering mechanism is arranged for a lockset, and the lockset comprises two flat rods. The steering mechanism comprises:

[0010] a mounting member;

[0011] Two sliding members are arranged to connect with the flat rods, and each of the two sliding members can move along a predetermined path relative to the mounting member, and the extending directions of the predetermined paths of the two sliding members have an included angle.

[0012] A connecting member is arranged to connect with the two sliding members at both ends to realize synchronous movement of the two sliding members, and at least part of the connecting member is arranged to be flexible.

[0013] In the above scheme, when in use, the steering mechanism is arranged close to the door, and the two flat rods are connected with the two sliding members, and the two flat rods and the two sliding members are synchronously moved under the influence of the connecting effect of the connecting member. Therefore, moving any one sliding member can realize the movement of the two flat rods, and then one of the flat rods can be gradually separated from the corresponding lock hole to realize unlocking, and the other flat rod can be gradually inserted into the corresponding lock hole to realize locking. This increases one locking point to better lock the door panel while reducing the operation difficulty. Compared with the way of moving the two flat rods separately, the structure is also simplified, so that the present application has the characteristics of simple structure, high efficiency and low failure rate.

[0014] The mounting member limits the movement path of the sliding member, and the flexible arrangement of the connecting member is suitable for the case where the extending directions of the predetermined paths of the two sliding members have an included angle.

[0015] Further technical solutions, the mounting member includes two assembly sub-members and a connecting sub-member; the two assembly sub-members are detachably connected through the connecting sub-member; at least one assembly sub-member is provided with a sliding groove corresponding to the arrangement of the two sliding members, and the predetermined path of the two sliding members is formed by the sliding groove.

[0016] Optionally, the sliding groove includes at least one sub-groove. The sliding member is arranged in the assembly sub-member by sliding through the sliding groove, and the sliding groove can include two sub-grooves, which are arranged separately to reduce the degree of modification of the assembly sub-member.

[0017] Through the above arrangement, the mounting member and the sliding member can be quickly assembled, and the sliding member can also be protected and the occupied space of the steering mechanism can be reduced.

[0018] Further technical solutions, both of the two assembly sub-members are provided with a guide member, and the two guide members are used to facilitate the stable splicing of the two assembly sub-members.

[0019] Before the two assembly sub-members are stably connected through the connecting sub-member, the two assembly sub-members are arranged relatively stably by the two guide members.

[0020] Further technical solutions, the two assembly sub-members can be enclosed to form an accommodation groove for accommodating the connecting member, and the accommodation groove is in communication with the sliding groove.

[0021] The connecting piece is arranged in the accommodating groove, on one hand, the connecting piece is enclosed and protected by the two assembled sub-pieces; on the other hand, since the area occupied by the connecting piece is in the area occupied by the two assembled sub-pieces, the area occupied by the steering mechanism can be reduced; on the other hand, the movement path of the connecting piece can be limited by the accommodating groove.

[0022] In a further technical solution, screw holes are arranged on the two assembled sub-pieces, and the connecting sub-piece comprises a nut and a stud.

[0023] In a further technical solution, the connecting piece is a steel sheet.

[0024] In a further technical solution, the included angle between the extension directions of the predetermined paths of the two sliding pieces is ninety degrees.

[0025] In a further technical solution, the flat rod has a hole; the sliding piece comprises a sliding sub-piece and a supporting sub-piece connected to each other; the sliding sub-piece is slidingly arranged in the mounting piece; the supporting sub-piece can support the flat rod through the hole to drive the flat rod to move.

[0026] Optionally, the hole is a square hole, and the supporting sub-piece comprises a square platform and a cylindrical structure connected to each other, and the cylindrical structure is connected to the sliding sub-piece; during installation, the square platform is arranged in the square hole until the square hole is arranged outside the cylindrical structure, and then the flat rod is rotated (e.g., by 45 degrees) to make the square platform and the edge of the square hole misaligned to avoid separation of the flat rod and the supporting sub-piece.

[0027] In a further technical solution, the connecting piece is arranged in the accommodating groove, on one hand, the connecting piece is enclosed and protected by the two assembled sub-pieces; on the other hand, since the area occupied by the connecting piece is in the area occupied by the two assembled sub-pieces, the area occupied by the steering mechanism can be reduced; on the other hand, the movement path of the connecting piece can be limited by the accommodating groove.

[0028] The sliding piece comprises a sliding sub-piece and a fixing sub-piece connected to each other; the sliding sub-piece is slidingly arranged in the mounting piece; the fixing sub-piece is detachably connected to the connecting piece through the adjacent through hole on the connecting piece.

[0029] For convenience of description, the connecting piece is taken as a steel sheet for example; the steel sheet is generally divided into a thin steel sheet and a thick steel sheet, wherein the thin steel sheet is softer and easier to bend, and the thick steel sheet is thicker and not easy to bend; when the thin steel sheet is used, it can move along a bending path (e.g., an arc path) because it is easy to bend, but the strength of the thin steel sheet is lower, which is not suitable for long-term use, which will affect the overall service life of the steering mechanism; by arranging multiple connecting pieces, multiple thin steel sheets can form a combined steel sheet, and the thickness of the combined steel sheet can be flexibly adjusted according to the number of thin steel sheets, which can realize movement along a bending path and avoid the problem of low strength, thereby improving the overall service life of the steering mechanism.
