Abstract
Description
Technical Field
[0001] The utility model relates to a hanging cage, in particular to a hanging cage flap door with good concealment. Background Art
[0002] The cage, also known as the construction elevator, is a vertical transportation machinery widely used in modern construction. It is mainly used for the up and down transportation of construction personnel, construction materials and construction machinery. The cage door is used to close the moving cage to protect the personnel or goods in the cage. Due to different scenarios, the cage door can be roughly divided into electric and manual. If it is divided into opening types in detail, it can be divided into flap doors, sliding doors, etc.
[0003] In the existing flap doors, an electric structure is adopted. For example, a chain is driven by a motor and then the chain pulls the flap door to slide up and down. However, although this method can make the cage door slide up and down, there is a gap between the cage and the floor door, which is very easy to cause accidents during the process of loading and unloading goods or personnel entering and exiting. However, if other docking structures are set, it is easy to affect the cage from passing through the floor door, and the safety is low. Especially in the process of the cage moving, if the structure falls directly, it will cause the cage or the floor door to deform, causing a safety accident. Utility Model Content
[0004] The utility model provides a cage flap door with good concealment. When the cage is moving, the docking structure between the cage and the floor door can be folded up to allow the cage to pass through each floor smoothly. Moreover, since it is arranged on the flap door, it is not easy to flip outward when the output node is incorrect, and the above-mentioned problem can be effectively solved.
[0005] The utility model is achieved in this way:
[0006] A cage flap door with good concealment, comprising: the cage flap door is arranged at the front end of the cage, two gears are arranged on both sides of the cage, one of the gears is driven by a motor, the two gears are connected by a chain, the two gears on the same side are fixed on a door frame, a locking assembly is rotatably installed at the bottom of the door frame, and a cage plate counter-pressure structure is connected to the locking assembly,
[0007] The cage plate back-pressure structure includes a back-pressure plate arranged between the two locking assemblies, and a counter-sticking piece is arranged on the inclined side of the back-pressure plate. When the back-pressure plate rotates with the locking assembly, the counter-sticking piece is fitted and fixed to the door plate of the cage flap door.
[0008] As a further improvement, the back pressure plate includes an arc-shaped plate fixedly connected to the locking assembly, a plurality of ribs are provided on the inner side of the arc-shaped plate, and the bottom of the ribs is an arc-shaped surface that matches the outer arc surface of the linkage rod on the locking assembly.
[0009] As a further improvement, a round conduit is provided at the end of the arc-shaped plate.
[0010] As a further improvement, a reinforcing rib is provided laterally on the rib, the reinforcing rib is adapted to the outer arc surface of the linkage rod, and after the linkage rod is rotated, the bottom of the reinforcing rib is attached to the outer side of the lower main beam of the cage.
[0011] As a further improvement, the anti-sticking member includes a plurality of magnetic sheets arranged on the arc plate, and after the arc plate rotates, the magnetic sheets are attracted to the door panel of the cage flap door.
[0012] As a further improvement, the rib is hollow, a spring is arranged inside the rib, the bottom of the magnetic sheet is fixed on the spring, and the magnetic sheet is higher than the arc plate.
[0013] As a further improvement, a sensing structure is provided on the side of the magnetic sheet, the sensing structure is a light sensor, and the light sensor is electrically connected to the motor of the driving gear.
[0014] The beneficial effects of the utility model are:
[0015] There is a certain gap between the cage and the floor door. If this gap is not interfered with, not only will there be a risk of people's feet being pinched when entering and exiting, but goods will also easily fall out of this gap and form falling objects from high altitude. Therefore, the utility model adopts a flap door and also provides a cage plate back-pressure structure. During the up and down movement of the cage, the back-pressure plate can be fitted and fixed to the door plate of the cage flap door through the back-sticker to prevent it from automatically flipping down and causing a jam on the up and down movement of the cage. It switches to a longitudinal state when the cage is moving, and switches to a transverse state when the cage stops. Since the back-pressure plate has a certain linkage relationship with the locking assembly, the cooperation between the back-sticker and the door plate can also interfere with the downward movement of the cage flap door to a certain extent.

DETAILED DESCRIPTION
[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are 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 making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.
[0027] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0028] Reference Figure 1 to Figure 6 As shown, a cage flap door with good concealment includes: the cage flap door is arranged at the front end of the cage 10, two gears 20 are arranged on both sides of the cage 10, one gear 20 is driven by a motor, and the two gears 20 are connected by a chain 30, and the cage flap door also includes: a locking buckle structure 40, two gears 20 on the same side are fixed on a door frame 11, and the locking buckle structure 40 includes a locking component 41 rotatably installed at the bottom of the door frame 11, and the chain 30 is locked with a linkage buckle 42, and the linkage buckle 30 is locked to the cage flap door. When the cage flap door moves downward, the linkage buckle 42 moves downward and drives the locking assembly 41 to flip toward the side of the cage 10; the cage plate back-pressure structure 50 includes a back-pressure plate 51 arranged between the two locking assemblies 41, and an anti-sticking member 52 is arranged on the inclined side of the back-pressure plate 51. When the back-pressure plate 51 rotates with the locking assembly 41, the anti-sticking member 52 is fitted and fixed to the door panel of the cage flap door.
[0029] In this embodiment, the cage flap door is moved straight up and down, that is, the driving method adopted is that the motor drives the gear 20 to rotate, and then the gear 20 drives the chain 30 to rotate. Since the cage flap door and the chain 30 have a certain connection relationship, the flap door will move accordingly during the rotation of the chain 30.
[0030] In the flap door structure of the prior art, the self-locking effect of the motor is relied upon to overcome the upward pushing effect of the flap door when the cage moves downward. However, once the self-locking effect of the motor fails, the flap door plate will automatically open, which is extremely dangerous. Therefore, the utility model provides a locking reverse buckle structure 40. During the downward movement of the cage flap door, the linkage buckle 42 connected to the cage flap door will move downward accordingly until it touches the locking assembly 41, causing the locking assembly 41 to rotate, thereby clamping and fixing the linkage buckle 42 through the locking assembly 41, thereby achieving mechanical clamping and fixing of the cage flap door. Even if the self-locking effect of the motor fails, the cage flap door can be clamped and fixed by the locking assembly 41, and the flap door will not open automatically.
[0031] In this embodiment, the locking assembly 41 is not unilaterally arranged, but is arranged in a set. Specifically, the locking assembly 41 includes two sets of rotating locking members 411 locked on the door frame 11. The two rotating locking members 411 are connected by a linkage rod 412. The bottom of the cage plate back pressure structure 50 is fixed on the linkage rod 412. The linkage rod 412 can not only ensure the synchronization state of the two rotating locking members 411, but also provide a basis for installation and attachment for the cage plate back pressure structure 50.
[0032] The entire rotary locking member 411 is in an active state, that is, it can switch its own state as the position of the external object changes. The rotary locking member 411 includes a mounting plate 4111 fixed to the door frame 11, and a bearing 4112 is installed on the mounting plate 4111. The side of the bearing 4112 away from the mounting plate 4111 is locked with an insert 4113. The linkage buckle 42 moves downward and is embedded in the insert 4113. During the rotation of the motor, the positional relationship between the linkage buckle 42 and the insert 4113 will determine whether the rotary locking member 411 rotates.
[0033] In order to allow the rotary locking member 411 to achieve two position changes, the linkage buckle 42 includes a driven plate 421 that cooperates with the chain 30, and the driven plate 421 is fixedly connected to the cage flap door through an adapter plate 422. The lower part of the driven plate 421 is connected to a rotating wheel 423, and the rotating wheel 423 is movably cooperated with the gap between the long arc handle 41132 and the short arc handle 41133, so that in the process of the linkage buckle 42 moving downward, it can touch the long arc handle 41132, so that the entire rotary locking member 411 is flipped over, forming a limit on the flap door, and in the process of resetting the linkage buckle 42, it can drive the short arc handle 41133 to reset the entire rotary locking member 411.
[0034] There is a certain gap between the cage 10 and the floor door. If this gap is not interfered with, not only will there be a risk of people's feet being pinched when entering and exiting, but goods will also easily fall out of this gap and form falling objects from high altitude. Therefore, the utility model adopts a flap door and also provides a cage plate back-pressure structure 50. During the up and down movement of the cage, the back-pressure plate 51 can be fixed to the door plate of the cage flap door through the anti-sticking member 52 to prevent it from automatically flipping down and causing a jam on the up and down movement of the cage. It switches to a longitudinal state when the cage is moving, and switches to a transverse state when the cage stops. Since the back-pressure plate 51 has a certain linkage relationship with the locking assembly 41, the cooperation between the anti-sticking member 52 and the door plate can also interfere with the downward movement of the cage flap door to a certain extent.
[0035] In order to have a certain strength, the back pressure plate 51 is not set as a straight plate structure. In the present embodiment, the back pressure plate 51 comprises an arc plate 511 fixedly connected to the linkage rod 412, and a plurality of ribs 512 are provided on the inner side of the arc plate 511. The bottom of the rib 512 is an arc surface matched with the outer arc surface of the linkage rod 412, so that the strength can be increased by matching the arched surface with the rib 512. Preferably, a circular conduit 513 is provided at the end of the arc plate 511 to form a better support at the end of the arc plate 511 to avoid deformation, curling, etc. at the end of the arc plate 511.
[0036] After the arc plate 511 is unfolded, in order to limit its flipping angle and also to increase its supporting force, a reinforcing rib 514 is provided on the side of the rib 512, and the reinforcing rib 514 is adapted to the outer arc surface of the connecting rod 412, and after the connecting rod 412 is rotated, the bottom of the reinforcing rib 514 is attached to the outer side of the lower main beam of the cage 10, so that it can be supported and fixed by a plurality of reinforcing ribs 514.
[0037] In this embodiment, the anti-sticking member 52 adopts a magnetic attraction method. Specifically, the anti-sticking member 52 includes a plurality of magnetic sheets 521 arranged on the arc plate 511. After the arc plate 511 rotates, the magnetic sheets 521 are attracted to the door panels of the cage flap door, thereby being able to cope with the vibration during the movement of the cage and avoiding the entire arc plate 511 from directly flipping down and getting stuck in the floor door when the mechanical interlocking structure fails.
[0038] After the magnetic sheet 521 is set, it will actually affect the movement of people and goods. Therefore, the rib 512 of this embodiment is hollow, and a spring 522 is arranged in the rib 512. The bottom of the magnetic sheet 521 is fixed on the spring 522. The magnetic sheet 521 is higher than the arc plate 511. After the flipping stage, the magnetic sheet 521 is hidden in the rib 512 and does not hinder the normal entry and exit of goods and people. In the attraction stage, the magnetic sheet 521 will pop out due to the magnetic force, thereby achieving a dual-use state without mutual hindrance.
[0039] In this embodiment, a sensing structure is provided on the side of the magnetic sheet 521. The sensing structure is a light sensor. The light sensor is electrically connected to the motor of the driving gear 20. When the arc plate 511 flips up, the sensing structure will be shielded. When the motor drives the flap door upward, the arc plate 511 will be displaced accordingly. However, the motor does not rotate directly into place at one time. It will initially run for 3 seconds and interact with the signal of the sensing structure to determine whether the arc plate 511 is flipped accordingly and whether personnel or goods can be protected by the arc plate 511 during the shipment stage, thereby determining whether to continue to drive the flap door to open.
[0040] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
