Description

Technical Field

[0001] This utility model relates to turnstiles, specifically to a horizontal fully automatic two-roller turnstile core. Background Technology

[0002] As a common access control device, the double roller turnstile is widely used in subway stations, office buildings, residential communities, airports and other places. Its core component is the mechanism, which directly affects the passage efficiency, security and space occupancy of the equipment. The following technical defects are commonly found in existing two-roller turnstile mechanisms: Firstly, the power mechanism mostly adopts a vertical motor layout. The vertical installation of the motor increases the overall height of the equipment and occupies a large space, which is not conducive to the space optimization design of modern buildings. Secondly, the locking mechanism mostly adopts a simple mechanical locking structure, which is prone to wear and jamming after long-term operation, resulting in unreliable locking and potential safety hazards for passage. Third, the unlocking response mechanism is simple, relying mainly on mechanical transmission for unlocking, which results in a slow response speed and cannot meet the needs for rapid passage in emergency situations. Fourth, some of the improved solutions have complex structures, numerous parts, and are difficult to maintain, and they have not effectively balanced the contradiction between space occupation and response speed. Therefore, there is an urgent need for a two-roller turnstile mechanism that is compact, reliable in locking, fast in response, and easy to maintain, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a horizontal fully automatic two-roller turnstile mechanism, which aims to solve the technical problems of large space occupation, unreliable locking, slow response speed and difficult maintenance of the existing two-roller turnstile mechanism.

[0004] To solve the above-mentioned technical problems, this utility model achieves the following solution: A horizontal fully automatic two-roller turnstile mechanism of this utility model includes: Power Department; A turntable assembly that is driven and connected to the power unit, the turntable assembly rotates in a circular motion after being driven.

The rotation directions of the two sets of gate rollers are in the same plane. They are set one-to-one with the two curved locking blocks, and a locking structure is formed between the curved locking blocks and their corresponding gate rollers. The unlocking mechanism is mounted on one side of the housing of the power unit. It has a telescopic part and a power source that drives the telescopic part to extend and retract. The extension and retraction direction of the telescopic part can intersect the path of rotation of the curved lock block, and the telescopic part can push open the unlocking end of the curved lock block after it extends.

[0005] Furthermore, the power unit is a motor module with a speed reducer.

[0006] Furthermore, the turntable assembly includes: The turntable has two symmetrical gate roller shaft connection parts on both sides of its surface.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1: The specific structure of this utility model is as follows: Please refer to the appendix. Figure 1-7 The present invention relates to a horizontal fully automatic two-roller gate mechanism, comprising: Power Unit 1; The turntable assembly 4 is driven and connected to the power unit 1, and the turntable assembly 4 rotates in a circular motion after being driven. Two curved locking blocks 5 are provided, and the two curved locking blocks 5 are symmetrically connected to the turntable assembly 4. The two curved locking blocks 5 can swing at both ends with the axis as the fulcrum. Two sets of gate rollers 3 are rotatably mounted at an angle on the turntable assembly 4. The rotation direction of the two sets of gate rollers 3 is in the same plane. They are set one-to-one with the two curved locking blocks 5. A locking structure is formed between the curved locking blocks 5 and their corresponding gate rollers 3. The unlocking mechanism 2 is mounted on one side of the housing of the power unit 1. It has a telescopic part and a power source for driving the telescopic part to extend and retract. The extension and retraction direction of the telescopic part can intersect the path of rotation of the curved locking block 5, and the telescopic part can push open the unlocking end 52 of the curved locking block 5 after it extends.

[0025] The power unit 1 is a motor module with a speed reducer. The motor module includes a motor and a speed reducer. The motor drives the speed reducer. The motor and the speed reducer are driven and connected by two vertically meshing bevel gears. The entire power unit 1 forms a horizontal structure, reducing the installation space.

[0026] The turntable assembly 4 includes: The turntable has two symmetrical gate roller shaft connection parts on both sides of its surface. The two sets of gate rollers 3 are connected one-to-one to the first shaft of the two gate roller shaft connection parts. Symmetrical shaft brackets are provided on both sides of the turntable. Two curved locking blocks 5 are rotatably mounted one-to-one on the second shaft of the two sets of shaft brackets. The first shaft and the second shaft are arranged parallel to each other at a certain distance.

[0027] The locking structure includes: An arc surface is provided on the outer wall of the shaft end of the gate roller 3 and a protrusion 31 is provided on one end of the arc surface. The protrusion 31 and the arc surface form an angle and the outer corner of the protrusion 31 is chamfered to form a first abutment surface 311. The second abutment surface 41 of the turntable is provided, and the first abutment surface 311 can abut against the second abutment surface 41; The locking end 51 of the curved locking block 5 is provided, and the locking end 51 abuts against the protrusion 31 to lock the gate roller 3, and the unlocking end 52 is rotated to unlock the gate roller 3.

[0028] The unlocking mechanism 2 also includes: The U-shaped frame 22 is mounted on one side of the housing of the power unit 1; Two telescopic rods 21 are movably inserted through the U-shaped frame 22, and the two telescopic rods 21 are perpendicular to the two side plates of the U-shaped frame 22; A magnetically pleasing piece 26 is fixed between the two telescopic rods 21 and is located within the U-shaped opening area of ​​the U-shaped frame 22; Two springs 24 are fitted one-to-one onto the two telescopic rods 21. One end of each spring 24 abuts against the magnetically attached piece 26, and the other end abuts against the U-shaped frame 22.

[0029] The telescopic part is an unlocking plate 27, which is fixed to the downward-facing end of the two telescopic rods 21.

[0030] Both ends of the unlocking plate 27 are bent toward the U-shaped frame 22, and the angle of the two ends of the unlocking plate 27 after bending is an obtuse angle.

[0031] The power source is an electromagnetic coil 23, which is fixed to the U-shaped frame 22. When the electromagnetic coil 23 is powered on, the magnetic field generated by it can act on the magnetically pleasing piece 26, causing the magnetically pleasing piece 26 to move towards the electromagnetic coil 23 to compress the two springs 24.

[0032] After the magnetically retractable piece 26 is magnetically attracted, the clearance space formed below the telescopic part is sufficient for the curved locking block 5 to pass through.

[0033] Example 2: The following is the working principle of this utility model's horizontal fully automatic double roller gate mechanism: like Figure 4 As shown, when the electromagnetic coil 23 is energized, it generates a magnetic field that attracts the magnetically attached piece 26, causing it to move upward and compress the spring 24. The magnetically attached piece 26 drives the two telescopic rods 21 to move upward synchronously. The unlocking plate 27 moves upward with the telescopic rods 21, moving away from the unlocking end 52 of the curved locking block 5. The unlocking end 52 is not subjected to external force, and the curved locking block 5 stably abuts against the protrusion 31, thus stably locking the two gate rollers 3. The power unit drives the turntable to rotate intermittently, causing the two gate rollers 3 to alternately block the gate passage. Personnel pass through the passage as the two gate rollers 3 rotate.

[0034] The locking end 51 of the curved locking block 5 remains in contact with the protrusion 31 of the gate roller 3; at the same time, the first contact surface 311 of the gate roller 3 abuts against the second contact surface 41 of the turntable, forming a double locking.

[0035] Emergency evacuation during power outage and roller drop: In the event of a power outage or emergency, the electromagnetic coil 23 loses power and the magnetic field disappears; the spring 24 releases its restoring force, pushing the magnetically pleasing plate 26 downwards, causing the telescopic rod 21 and the unlocking plate 27 to extend synchronously. The unlocking plate 27 presses against the unlocking end 52 of the curved locking block 5, the curved locking block 5 descends, the locking end 51 disengages from the protrusion 31, and the gate roller 3 falls freely under gravity, forming a drop like... Figure 7 The passageway is clear and unobstructed, facilitating emergency evacuation of personnel.

[0036] The device is restored after a power-on reset emergency. Once the emergency is resolved, the device is powered on, the electromagnetic coil 23 is re-energized, the magnetically attracted piece 26 moves upward, the unlocking plate 27 retracts, leaving room for the curved locking block 5 to rotate.

[0037] The power unit 1 drives the turntable to rotate, causing the gate roller 3, which was hanging down and not locked, to swing to a vertical position by its own weight. During the process of swinging to a vertical position, the protrusion 31 on it will re-engage with the locking end 51 of the curved locking block 5 to form a locking structure.

[0038] In summary, the two-roller gate mechanism of this utility model adopts a horizontal motor module with bevel gear transmission, which greatly reduces the overall height of the equipment, has a compact structure, saves installation space, and is suitable for the space optimization needs of modern buildings. The curved locking block of this utility model forms a double-abutment locking structure with the gate roller, which is reliable, wear-resistant, and effectively avoids the problem of locking failure after long-term operation, thus improving traffic safety. The unlocking mechanism of this utility model's two-roller turnstile core adopts electromagnetic control, which has a short response time. When the power is cut off, the upper turnstile roller is unlocked and falls freely, ensuring unobstructed passage in emergency situations and meeting the needs of sudden evacuation. The overall structure of this utility model of the two-roller gate mechanism is simple, with few parts, easy to install and disassemble, and low maintenance cost. It is suitable for high-frequency passage occasions and has broad application prospects.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
