[0001] The utility model relates to a deadweight door lock structure for a construction elevator and belongs to the technical field of elevators. Background Art

[0002] The spring force of the spring-type door lock is large, the resistance to retraction of the door lock block is large, the efficiency of door opening and closing is low, and frequent opening and closing of the door causes the door lock to deform. The deadweight door lock mechanism is installed on the elevator cage door, and the door lock is opened and closed as the cage door rises and falls. Utility Model Content

[0003] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a self-weight door lock structure for a construction elevator, and the auxiliary function of a block, which can retract the self-weight door lock through less resistance, thereby effectively solving the problem of deformation of the current spring door lock during use, and can not only meet the requirements of automatic opening and closing of the elevator door, but also improve the stability of product quality.

[0004] The utility model is realized through the following technical scheme: a self-weight door lock structure for a construction elevator, characterized in that it includes a door lock frame, a door lock block and a lock handle, an axial hole is provided at the bottom of the door lock block, the door lock block is hinged on the door lock frame through bolts and nuts, the lock handle is fixed on the door lock block, the lock handle is arranged on the outside of the door lock block, and the lock handle drives the door lock block to tilt forward in a freely placed state.

[0005] The lock handle drives the door lock block through the limit of the stop block.

[0006] The beneficial effects of the utility model are: simple structural design, light structure, and easy use; no need to rely on spring elastic force, rotation is achieved through center of gravity offset, and cost is reduced; the thickness of the door lock block is increased, and it has better durability.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present utility model, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present utility model; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0017] like Figures 1 to 6 The self-weight door lock structure of a construction elevator shown in the figure includes a door lock frame 1, a door lock block 2 and a lock handle 3. The door lock block 2 is provided with an axial hole 4 at the bottom. The door lock block 2 is hinged to the door lock frame 1 through bolts 5 and nuts. The lock handle 3 is fixed to the door lock block 2. The lock handle 3 is arranged on the outside of the door lock block 2. The lock handle 3 drives the door lock block 2 to tilt forward when it is freely placed.

[0018] The lock handle 3 drives the door lock block 2 through the limit of the stop block 6.

[0019] The deadweight door lock block 2 and the lock handle 3 replace the original spring door lock mechanism. The door lock is connected with a bolt 5 so that it can rotate around the bolt 5. In the normal placement state, the door lock block 2 rotates downward due to gravity to open. When the device runs at the stopper 6, the stopper 6 touches the deadweight door lock handle 3 and the lock block rotates upward to close. Compared with the spring door lock, it has the characteristics of being convenient, simple and durable.

[0020] The self-weight door lock can be combined with the bottom cage door lock block. When the cage door rises, the self-weight door lock installed on the cage gradually leaves the cage door lock block 6, and the lock handle 3 on one side leaves the restriction of the block 6, and the door lock block 2 resumes its free state, that is, it rotates downward freely. After the door lock block 2 is opened, the lock block presses against the bottom cage door lock block and interlocks with the bottom cage door lock block. When the cage door descends, the door lock block 2 is retracted due to the obstruction of the lock block, and the same interlocking function as the spring door lock is realized, but it is more efficient and durable.

[0021] like Figure 5 As shown, the lock handle 3 is put into the block 6 due to the lowering of the cage door. After the block 6 restricts the lock handle 3, the door lock block rotates upward and retracts to close the cage door, and the elevator can run automatically.

[0022] After the lock handle 3 leaves the stopper 6, the door lock block is in an automatic placement state due to its center of gravity being forward, that is, the door lock block 2 automatically rotates forward around the bolt 5 as an axis;

[0023] The door lock block 2 cooperates with the bottom cage door lock block to form an interlock, so that when the cage door opens, the bottom cage door is driven to open, realizing the automatic door opening function.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
