Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a panoramic door transmission and locking system. Background Technology

[0002] High-end panoramic doors and windows are designed with a wide field of view and high transparency as their core features. The requirements for locks far exceed those of ordinary doors and windows. They need to achieve systematic coordination in terms of security, load-bearing capacity, sealing, weather resistance, and aesthetics. Currently, the transmission and locking systems of panoramic doors on the market generally have shortcomings. Specifically, when using gear and rack transmission, there is no self-locking property, which makes the door leaf unable to stop and can be easily pushed by external force, making it ineffective in preventing theft. In addition, the high precision of the manufacturing process results in poor fault tolerance, requiring the addition of an electric lock, which increases the complexity and cost of the system. Worm gear transmission has low transmission efficiency, heavy operation, difficulty in opening, serious heat generation, and requires a large space, resulting in high manufacturing costs. Linkage transmission has good load-bearing and impact resistance, high sealing performance, long service life, and multi-point locking security and reliability, and has low manufacturing costs. However, the disadvantages are low transmission precision, poor balance of inertial forces in the mechanism, potential vibration and noise during rapid operation, and often no anti-misoperation measures, which can easily damage the door leaf and hardware. Utility Model Content

[0003] This utility model discloses a panoramic door transmission and locking system to overcome the shortcomings of the prior art.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A panoramic door transmission and locking system includes a door frame and a door body. A lock body is mounted on the door body, and a lock seat is mounted on the door frame. The lock seat has a pair of double-hook lock holes. A slide rail and a sliding lock seat are mounted on the door frame. An anti-misoperation device is mounted on the slide rail. The upper and lower ends of the locking plate are respectively fixedly connected to a sliding lock seat via a transmission bar. Two lock hooks are mounted on the lock body via a lock hook fixing shaft. The lock hooks can rotate around the lock hook fixing shaft. The lock body also has a locking plate and a square-hole shift fork. The locking plate is provided with two shift lever shafts and a shift fork hole. The lock hooks are provided with shift lever grooves, and the shift lever shafts are located in the shift lever grooves. Inside, a fork part is provided on the square hole fork, which is located in the fork hole. By rotating the square hole fork, the fork part can be moved up and down, thereby driving the locking plate to move up and down in the lock body. The up and down movement of the locking plate causes the lever shaft to move up and down, thereby enabling the lock hook to rotate. The two lock hooks rotate in opposite directions. The lock body has two states. The first state is the unlocked state, in which the lock hook is not turned out and is completely hidden in the lock body. The second state is the locked state, in which the lock hook is turned out and screws into the double hook lock hole to hook the lock seat to achieve locking.

[0006] The sliding lock seat and the transmission bar are both installed in the slide groove of the slide rail and can slide up and down in the slide groove. The slide rail is provided with a first limiting hole, and the sliding lock seat is provided with a first limiting slide groove, a second limiting slide groove, a second limiting hole and a third limiting slide groove. The width of the first limiting slide groove is smaller than the diameter of the second limiting hole.

[0007] An adjustable locking point assembly is installed on the frame. The adjustable locking point assembly has a base, on which a bumper block, a round lock head, and a top rod are installed. The top of the round lock head has a guide rod part and a lock head. The diameter of the lock head is smaller than the width of the second limiting slide groove, the diameter of the lock head is larger than the width of the third limiting slide groove, and the diameter of the guide rod part is smaller than the width of the limiting slide groove.

[0008] The anti-misoperation device consists of an anti-misoperation device base, an anti-misoperation pin, and an anti-misoperation spring. The anti-misoperation device base is provided with a pin mounting groove. The anti-misoperation pin consists of a stepped shaft with a large end and a small end. The diameter of the large end of the pin is larger than the diameter of the small end. The anti-misoperation pin and the anti-misoperation spring are installed in the pin mounting groove. The anti-misoperation pin can move under the action of the anti-misoperation spring.

[0009] The anti-misinsertion pin is concentrically set with the first limiting hole and can be inserted into the first limiting hole. The diameter of the first limiting hole is smaller than the diameter of the pin mounting groove. When the lock body is in the first state, the small end of the pin is inserted into the first limiting hole, and the large end of the pin is inserted into the second limiting hole. The round lock head is located in the second limiting groove. At this time, the sliding lock seat cannot move up or down. When the lock body is in the second state, the small end of the pin is pushed out of the first limiting hole by the push rod, and the large end of the pin is pushed out of the second limiting hole. The sliding lock seat moves down a distance under the action of the lock body. At this time, the small end of the pin is located in the first limiting groove, and the round lock head is located in the third limiting groove. The lock head hooks the edge of the third limiting groove, preventing the sash frame from moving.

[0010] There are at least two sliding lock seats and adjustable locking point assemblies, located at the upper and lower ends of the lock body, respectively.

[0011] The lock hook has two lever slots, which are symmetrically arranged with respect to the lock hook fixing axis.

[0012] The lock body is provided with a lock cylinder mounting hole, a lock cylinder assembly is installed in the lock cylinder mounting hole, and a lock cylinder cover is provided on the end of the lock cylinder assembly where the key is installed.

[0013] The square hole fork is provided with a square hole that mates with the drive shaft of the knob handle assembly.

[0014] The mounting key ends of the knob handle assembly and the lock cylinder assembly are located on both sides of the lock body, and the knob handle assembly and the lock cylinder assembly rotate synchronously, both of which can drive the lock plate to move up and down.

[0015] The beneficial effects of this utility model are: it adopts a double hook with locking points at both ends, providing multi-point locking, making it impossible to pry out, with high security and anti-pry performance; it uses an anti-misoperation device and a double hook lock body, with the lock body and anti-misoperation device working together to prevent accidental damage to the door leaf and hardware; it has good sealing performance and closes tightly; the high-strength lock hooks and double hook lock seats work together, and the adjustable locking points work together with the sliding lock seat, allowing for adjustable overlap gaps to achieve a tight fit; the anti-misoperation device and lock body are concealed inside the door leaf, providing high anti-theft performance.

The lock body 7 is also equipped with a locking plate 73 and a square hole shift fork 72. The locking plate 73 is provided with two shift lever shafts 74 and a shift fork hole 731. The lock hooks 71 are provided with shift lever grooves 76, and the shift lever shafts 74 are provided in the shift lever grooves. Inside the lock body 76, a fork part 721 is provided on the square hole fork 72. The fork part 721 is located in the fork hole 731. By rotating the square hole fork 72, the fork part 721 can move up and down, thereby driving the locking slide plate 73 to move up and down within the lock body 7. The up and down movement of the locking slide plate 73 causes the lever shaft 74 to move up and down, thereby enabling the locking hook 71 to rotate. The two locking hooks 71 rotate in opposite directions. The lock body 7 has two states. The first state is the unlocked state, in which the locking hook 71 is not unscrewed and is completely hidden inside the lock body 7. The second state is the locked state, in which the locking hook 71 is unscrewed and screws into the double hook lock hole 81 to hook the lock seat 8 and achieve locking.

[0030] The sliding lock seat 4 and the transmission bar 13 are both installed in the slide groove 32 of the slide rail 3 and can slide up and down in the slide groove 32. The slide rail 3 is provided with a first limiting hole 31, and the sliding lock seat 4 is provided with a first limiting slide groove 41, a second limiting slide groove 42, a second limiting hole 43 and a third limiting slide groove 44. The width of the first limiting slide groove 41 is smaller than the diameter of the second limiting hole 43.

[0031] The frame 2 is equipped with an adjustable locking point assembly 5. The adjustable locking point assembly 5 has a base 51. The base 51 is equipped with a bumper block 52, a round lock head 53 and a top rod 54. The top of the round lock head 53 has a guide rod part 531 and a lock head 532. The diameter of the lock head 532 is smaller than the width of the second limiting slide groove 42 and larger than the width of the third limiting slide groove 44. The diameter of the guide rod part 531 is smaller than the width of the limiting slide groove 44.

[0032] The anti-misoperation device 9 consists of an anti-misoperation device base 91, an anti-misoperation pin 92, and an anti-misoperation spring 93. The anti-misoperation device base 91 is provided with a pin mounting groove 911. The anti-misoperation pin 92 consists of a stepped shaft with a large end 921 and a small end 922. The diameter of the large end 921 is larger than the diameter of the small end 922. The anti-misoperation pin 92 and the anti-misoperation spring 93 are installed in the pin mounting groove 911. The anti-misoperation pin 92 can move under the action of the anti-misoperation spring 93.

[0033] The anti-misinsertion pin 92 is concentrically set with the first limiting hole 31 and can be inserted into the first limiting hole 31. The diameter of the first limiting hole 31 is smaller than the diameter of the pin mounting groove 911. When the lock body 7 is in the first state, the small end 922 of the pin is inserted into the first limiting hole 31, and the large end 921 of the pin is inserted into the second limiting hole 43. The round lock head 53 is located in the second limiting slide groove 42. At this time, the sliding lock seat 4 cannot move up and down. When the lock body 7 is in the second state, the small end 922 of the pin is pushed out of the first limiting hole 31 by the action of the push rod 54, and the large end 921 of the pin is pushed out of the second limiting hole 43. The sliding lock seat 4 moves down a certain distance under the action of the lock body 7. At this time, the small end 922 of the pin is located in the first limiting slide groove 41, and the round lock head 53 is located in the third limiting slide groove 44. The lock head 532 hooks the edge of the third limiting slide groove 44, making the fan frame 1 unable to move.

[0034] There are at least two sliding lock bases 4 and adjustable locking point assemblies 5, which are located at the upper and lower ends of the lock body 7, respectively.

[0035] The locking hook 71 has two lever grooves 76, which are symmetrically arranged relative to the locking hook fixing axis 75.

[0036] The lock body 7 is provided with a lock cylinder mounting hole 77, a lock cylinder assembly 11 is installed in the lock cylinder mounting hole 77, and a lock cylinder cover 12 is provided on the end of the lock cylinder assembly 11 where the key is installed.

[0037] The square hole fork 72 is provided with a square hole that mates with the drive shaft 101 of the knob handle assembly 10.

[0038] The key ends of the knob handle assembly 10 and the lock cylinder assembly 11 are located on both sides of the lock body 7, and the knob handle assembly 10 and the lock cylinder assembly 11 rotate synchronously, both of which can drive the lock slide plate 73 to move up and down.

[0039] In practical applications, a slide rail 3 and a sliding lock seat 4 are installed on the fan frame 1. An anti-misoperation device 9 is installed on the slide rail 3. The upper and lower ends of the locking plate 73 are respectively fixedly connected to a sliding lock seat 4 via a transmission bar 13. Two locking hooks 71 are installed on the lock body 7 via a locking hook fixing shaft 75. The locking hooks 71 can rotate around the locking hook fixing shaft 75. The lock body 7 is also equipped with a locking plate 73 and a square hole shift fork 72. The locking plate 73 is provided with two shift rod shafts 74 and a shift fork hole 731. The locking hooks 71 are provided with shift rod grooves 76, and the shift rod shafts 74 are located in the shift rod grooves 76. The square hole shift fork 72 is provided with a shift fork part 721, which is located in the shift fork hole 731. By rotating the square hole shift fork 72, the shift fork part 721 can move up and down, thereby driving the lock body. The locking plate 73 moves up and down within the lock body 7. This movement of the locking plate 73 causes the lever shaft 74 to move up and down, thereby rotating the locking hooks 71. The two locking hooks 71 rotate in opposite directions. There are two lever grooves 76 on each locking hook 71, symmetrically arranged relative to the locking hook fixing shaft 75. The lock body 7 has a lock cylinder mounting hole 77, in which a lock cylinder assembly 11 is installed. A lock cylinder cover 12 is provided on the key-mounting end of the lock cylinder assembly 11. A square hole fork 72 has a square hole that mates with the drive shaft 101 of the knob handle assembly 10. The key-mounting ends of the knob handle assembly 10 and the lock cylinder assembly 11 are located on opposite sides of the lock body 7, and they rotate synchronously. Both can drive the sliding plate 73 to move up and down. When the sash frame 1 and the frame 2 are separated, the lock body 7 is in the first state. At this time, the lock hook 71 is not unscrewed and is completely hidden inside the lock body 7. The small end 922 of the pin is inserted into the first limiting hole 31, and the large end 921 of the pin is inserted into the second limiting hole 43. The round lock head 53 is located in the second limiting groove 42. At this time, the sliding lock seat 4 cannot move up and down. When it is necessary to close the window, the sash frame 1 is moved towards the frame 2. When it moves to the point where the top rod 54 pushes against the small end 922 of the pin and pushes the small end 922 out of the first limiting hole 31 and the large end 921 out of the second limiting hole 43, the sliding lock seat 4 is in the unlocked state and the up and down movement of the sliding lock seat 4 is not possible. Affected by this, when the lock cylinder assembly 11 or the square hole fork 72 is turned, the square hole fork 72 or the fork on the lock cylinder assembly 11 will move the lock plate 73 downward. The sliding lock seat 4 and the transmission bar 13 are both installed in the slide groove 32 of the slide rail 3. The upper and lower ends of the lock plate 73 are respectively fixedly connected to a sliding lock seat 4 through the transmission bar 13. The lock plate 73 then drives the sliding lock seat 4 to move downward synchronously until the lock hook 71 rotates and is screwed into the double hook lock hole 81 to hook the lock seat 8 and achieve locking. At this time, the small end 922 of the pin is located in the first limiting slide groove 41, and the round lock head 53 is located in the third limiting slide groove 44. The lock head 532 hooks the edge of the third limiting slide groove 44, making the fan frame 1 unable to move, thereby achieving locking between the lock body 7 and the lock seat 8.Meanwhile, the slide rail 3 and the sliding lock seat 4 are locked together via the lock head 532. Since there are at least two sliding lock seats 4 and adjustable locking point assemblies 5, located at the upper and lower ends of the lock body 7 respectively and arranged symmetrically with respect to the lock body 7, there are at least three fixed points between the fan frame 1 and the frame 2. Furthermore, when the top rod 54 is not pressed against the small end 922 of the pin, the sliding lock seat 4 cannot move. Therefore, the anti-misoperation device 9 prevents the lock cylinder from being unable to be turned when the fan frame 1 and the frame 2 are not closed. Component 11 or square hole fork 72 enables the anti-misoperation function, ensuring stable and reliable fixation that cannot be pried out, providing high security and anti-pry performance. The anti-misoperation device 9 and double-hook lock body work together, with the lock body 7 and anti-misoperation device 9 cooperating to prevent accidental operation of 9 from damaging the door leaf and hardware. It offers good sealing and tight closure. High-strength lock hook 71 cooperates with double-hook lock seat 8, and adjustable locking point component 5 cooperates with sliding lock seat 4, allowing for adjustable overlap gaps to achieve a tight fit. The anti-misoperation device 9 and lock body are discreetly embedded within the door leaf, providing high anti-theft performance.

[0040] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
