Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of locks, and in particular relates to a lock body structure. Background Art
[0002] In modern life, the bathroom is an important functional area in the home, and its safety and convenience have attracted much attention. Traditional bathroom doors can only be opened from the inside after being locked, which may cause inconvenience or even safety hazards in some specific situations. From a safety perspective, when an unexpected situation occurs, such as a fire, earthquake, or the owner suddenly faints in the bathroom, the bathroom door cannot be unlocked from the inside, making it difficult for outsiders to enter for rescue, which may delay the best time for rescue.
[0003] For example, Chinese patent publication number CN215565071U discloses a lock body structure, including:
[0004] The lock body shell is provided with a lining plate for a lock tongue hole; a limiting groove component is provided on one side of the lock body shell close to the lock tongue hole, and a side hole is provided on one side wall; the flip tongue is provided in the open end of the limiting groove component, can move along the length of the limiting groove component, is provided with a limiting protrusion on its side, and is provided with a card slot at its rear end, and a limiting card plate with a length greater than the width of the flip tongue is provided on the side wall on one side of the card slot, and the front end of the flip tongue passes through the lock tongue hole; a positioning spring is provided in the limiting groove component, one end of which is connected to the bottom surface of the limiting groove component, and the other end applies elastic force to the bottom surface of the card slot; the locking assembly is rotatably mounted on a pin shaft provided on the lock body shell, one end of which can extend into the limiting groove component through the side hole and abut against the limiting card plate; an unlocking assembly for controlling the rotation of the locking assembly, and a handle for controlling the rotation of the unlocking assembly.
[0005] The above patent has the following problems:
[0006] This patent has some shortcomings when used, such as: when a person needs to release the door lock, the unlocking component cooperates with the knob handle. If the operation is wrong, it may affect the normal operation of the unlocking component, and then affect the locking state of the flip tongue by the locking component. In an emergency, such as fire, earthquake or the owner suddenly fainted in the bathroom, the outdoor personnel may not be able to accurately operate the knob handle due to nervousness. If the knob handle cannot be operated quickly and accurately to control the unlocking component, the locking component may not be able to release the lock of the flip tongue in time, delaying the rescue time. The open end of the limit groove component is opposite to the lock tongue hole. When the lock body is installed and used, it is necessary to ensure the alignment accuracy of the limit groove component and the lock tongue hole. Otherwise, it may affect the normal extension and retraction of the flip tongue, thereby affecting the function of the lock. In view of this, we propose a lock body structure. Utility Model Content
[0007] The purpose of the present invention is to provide a lock body structure to solve the problems raised in the above background technology.
[0008] In view of this, the present invention provides a lock body structure, including a lock seat and further comprising:
[0009] The baffle is fixedly mounted on the left side of the lock seat, a lock tongue is slidably mounted in the lock seat, one end of the lock tongue passes through the lock seat and the baffle and extends to the outside, a positioning block is fixedly mounted in the lock seat and on the right side of the lock tongue, a push pin is fixedly mounted on the right end of the lock tongue and located in the lock seat, one end of the push pin passes through the positioning block, and a spring is sleeved on the push pin and located between the lock tongue and the positioning block;
[0010] A transmission plate is rotatably mounted in the lock seat and is located between the positioning block and the tail end of the push slide pin;
[0011] The base is snap-fitted to the transmission plate, and one end of the base passes through the transmission plate and the inner wall of the lock seat and is fixedly installed with a handle 1, a cover plate is provided on the rear side of the lock seat, and the other end of the base passes through the cover plate and is fixedly installed with a handle 2, a slide groove 1 is provided in the lock seat and on the right side of the push slide pin, a rack plate is slidably installed in the slide groove 1, one side of the rack plate is meshed with a half gear installed in the lock seat, a knob fixed with the half gear is rotatably installed in the cover plate, a slide groove 2 is provided on the inner wall of the lock seat, a sliding rod fixed with the half gear is slidably installed in the slide groove 2, and a counterweight is fixedly installed on the sliding rod;

[0013] Four side panels are all plugged and installed on the rear side of the lock seat, and two of the side panels cover the second slide groove and the rectangular groove.
[0014] When the user releases the handle 2, the spring 1 rebounds and stretches, squeezing one end of the lock tongue out of the lock seat and penetrating the baffle.
[0015] When the person needs to lock the lock body and the spring is in a naturally extended state, the person rotates the knob clockwise by hand, and the rotating knob drives the half gear to rotate, and the rotating half gear drives one end of the sliding rod to slide along the second slide groove, and the sliding sliding rod drives the counterweight block to move. At the same time, the rotation of the half gear drives the rack plate to slide upward along the first slide groove, and then the rack plate moves to the rear side of one end of the push slide pin. Because the push slide pin is blocked by the rack plate, the push slide pin cannot drive the lock tongue to move, so that the lock tongue cannot be retracted into the lock seat. Under the combined action of gravity and the counterweight block, the half gear cannot reverse and can continuously keep the rack plate behind one end of the push slide pin, thereby achieving the purpose of locking;
[0016] When a person locks the lock body in the bathroom and an emergency occurs, such as fire, earthquake or a family member suddenly fainting, and the lock needs to be released, someone outside the door can pull out two side panels on the lock seat. Then, the person lifts one end of the sliding rod along the second slide groove by hand. The lifted sliding rod drives the half gear to rotate counterclockwise and drives the rack plate to slide downward along the first slide groove. When the sliding rod contacts the blocking rod, the person detents the rectangular slider, causing the rectangular slider to drive the blocking rod to move toward the blocking block. At this time, the second spring is squeezed by the blocking rod and contracts to generate a large elastic force. At the same time, the person continues to lift the sliding rod along the second slide groove. , Then the personnel releases the rectangular slider, and under the action of the rebound force of spring 2, one end of spring 2 squeezes the blocking rod to move in the direction of the sliding rod until one end of the blocking rod rests on one end of the sliding rod. Then, the personnel holds handle 1 with his left hand, presses handle 1 counterclockwise and drives the base to rotate. The rotating base drives the transmission plate to rotate counterclockwise, and one side of the transmission plate squeezes the push pin, so that one end of the push pin slides in the positioning block. Then, the other end of the push pin drives the lock tongue to completely enter the lock seat, thereby unlocking the lock body, ensuring that the lock body can be quickly released when it is locked. No professional equipment is required to operate the equipment, thus avoiding delays in rescue time.
[0017] By setting the half gear and rack plate, it is ensured that the rotation of the half gear drives the rack plate to slide up and down along the slide groove to achieve locking and unlocking, ensuring the reliability of the lock body and avoiding the decrease of alignment accuracy which affects the function of the lock.
[0018] When the user releases the handle 2, the spring 1 rebounds and stretches, squeezing one end of the lock tongue out of the lock seat and penetrating the baffle.
[0019] When the person needs to lock the lock body and the spring is in a naturally extended state, the person rotates the knob clockwise by hand, and the rotating knob drives the half gear to rotate, and the rotating half gear drives one end of the sliding rod to slide along the second slide groove, and the sliding sliding rod drives the counterweight block to move. At the same time, the rotation of the half gear drives the rack plate to slide upward along the first slide groove, and then the rack plate moves to the rear side of one end of the push slide pin. Because the push slide pin is blocked by the rack plate, the push slide pin cannot drive the lock tongue to move, so that the lock tongue cannot be retracted into the lock seat. Under the combined action of gravity and the counterweight block, the half gear cannot reverse and can continuously keep the rack plate behind one end of the push slide pin, thereby achieving the purpose of locking;
[0020] When a person locks the lock body in the bathroom and an emergency occurs, such as fire, earthquake or a family member suddenly fainting, and the lock needs to be released, someone outside the door can pull out two side panels on the lock seat. Then, the person lifts one end of the sliding rod along the second slide groove by hand. The lifted sliding rod drives the half gear to rotate counterclockwise and drives the rack plate to slide downward along the first slide groove. When the sliding rod contacts the blocking rod, the person detents the rectangular slider, causing the rectangular slider to drive the blocking rod to move toward the blocking block. At this time, the second spring is squeezed by the blocking rod and contracts to generate a large elastic force. At the same time, the person continues to lift the sliding rod along the second slide groove. , Then the personnel releases the rectangular slider, and under the action of the rebound force of spring 2, one end of spring 2 squeezes the blocking rod to move in the direction of the sliding rod until one end of the blocking rod rests on one end of the sliding rod. Then, the personnel holds handle 1 with his left hand, presses handle 1 counterclockwise and drives the base to rotate. The rotating base drives the transmission plate to rotate counterclockwise, and one side of the transmission plate squeezes the push pin, so that one end of the push pin slides in the positioning block. Then, the other end of the push pin drives the lock tongue to completely enter the lock seat, thereby unlocking the lock body, ensuring that the lock body can be quickly released when it is locked. No professional equipment is required to operate the equipment, thus avoiding delays in rescue time.
[0021] By setting the half gear and rack plate, it is ensured that the rotation of the half gear drives the rack plate to slide up and down along the slide groove to achieve locking and unlocking, ensuring the reliability of the lock body and avoiding the decrease of alignment accuracy which affects the function of the lock.
[0022] In this technical solution, the structural stability of spring 2 is ensured, and the tail end of the blocking rod can be normally received in the blocking block, so that the blocking rod can be away from the sliding rod, and the structural stability of the lock seat and the blocking block is ensured.
[0023] In the above technical solution, further, four cross screws are threadedly installed on the cover plate, one end of the cross screw extends into the lock seat, and one end of the cross screw is threadedly connected to the lock seat.
[0024] In this technical solution, four cross screws are provided to ensure that the cover plate can be firmly fixed to the rear side of the lock seat, thereby ensuring the structural stability of the lock seat and the cover plate.

[0050] Example 1:
[0051] See also Figure 1 - Figure 9 As shown, this embodiment provides a lock body structure, including a lock seat 1, and also includes:
[0052] Baffle 2, baffle 2 is fixedly mounted on the left side of the lock seat 1, a lock tongue 3 is slidably mounted in the lock seat 1, one end of the lock tongue 3 passes through the lock seat 1 and the baffle 2 and extends to the outside, a positioning block 6 is fixedly mounted in the lock seat 1 and on the right side of the lock tongue 3, a push pin 8 is fixedly mounted on the right end of the lock tongue 3 and located in the lock seat 1, one end of the push pin 8 passes through the positioning block 6, and a spring 7 is sleeved on the push pin 8 and between the lock tongue 3 and the positioning block 6;
[0053] The transmission plate 10 is rotatably mounted in the lock seat 1 and is located between the positioning block 6 and the tail end of the push slide pin 8;
[0054] The base 11 is snap-fitted and mounted on the transmission plate 10, and one end of the base 11 passes through the transmission plate 10 and the inner wall of the lock seat 1 and is fixedly mounted with a handle 1 21. A cover plate 4 is provided on the rear side of the lock seat 1, and the other end of the base 11 passes through the cover plate 4 and is fixedly mounted with a handle 221. A slide groove 19 is provided in the lock seat 1 and on the right side of the push pin 8. A rack plate 18 is slidably mounted in the slide groove 19. A half gear 12 is meshed and mounted on one side of the rack plate 18 and located in the lock seat 1. A knob 22 fixed to the half gear 12 is rotatably mounted in the cover plate 4. A slide groove 2 17 is provided on the inner wall of the lock seat 1. A sliding rod 13 fixed to the half gear 12 is slidably mounted in the slide groove 2 17, and a counterweight is fixedly mounted on the sliding rod 13.
[0055] Rectangular groove 19, rectangular groove 19 is opened on one side of slide groove 2 17, rectangular slide block 23 is slidably installed in rectangular groove 19, one end of rectangular slide block 23 is fixedly installed in lock seat 1 and a blocking rod 16 is abutted against one end of sliding rod 13, and the tail end of blocking rod 16 is provided with spring 2 15 and blocking block 14;
[0056] Four side panels 20 are all plugged and installed on the rear side of the lock base 1 , and two of the side panels 20 cover the second slide groove 17 and the rectangular groove 19 .
[0057] When the operator needs to unlock the lock body, the operator holds the handle 221 with his hand and presses the handle 221 clockwise, so that the handle 221 rotates clockwise. The clockwise rotating handle 221 drives the base 11 to rotate, and the rotating base 11 drives the transmission plate 10 to rotate clockwise, ensuring that one end of the transmission plate 10 can squeeze one end of the push slide pin 8 to slide in the positioning block 6. Subsequently, the other end of the push slide pin 8 drives the lock tongue 3 to completely enter the lock seat 1. At the same time, by arranging a spring 17 between the positioning block 6 and the lock tongue 3, it is ensured that when the spring 17 is squeezed by the positioning block 6 and the lock tongue 3, the spring 17 will contract and generate a large elastic force. When the operator releases the handle 221, under the action of the rebound force of the spring 17, the spring 17 rebounds and stretches and squeezes one end of the lock tongue 3 to move out of the lock seat 1 and pass through the baffle 2.
[0058] When the personnel needs to lock the lock body, and the spring 17 is in a naturally extended state, the personnel rotates the knob 22 clockwise by hand, and the rotating knob 22 drives the half gear 12 to rotate. The rotating half gear 12 drives one end of the sliding rod 13 to slide along the sliding groove 17, and the sliding sliding rod 13 drives the counterweight to move. At the same time, the rotation of the half gear 12 drives the rack plate 18 to slide upward along the sliding groove 19. Subsequently, the rack plate 18 moves to the rear side of one end of the push slide pin 8. Because the push slide pin 8 is blocked by the rack plate 18, at this time, the push slide pin 8 cannot drive the lock tongue 3 to move, so that the lock tongue 3 cannot be retracted into the lock seat 1. Under the combined action of gravity and the counterweight, the half gear 12 cannot be reversed, and can continuously keep the rack plate 18 behind one end of the push slide pin 8, thereby achieving the purpose of locking;
[0059] When a person locks the lock body in the bathroom and an emergency occurs, such as a fire, an earthquake, or a family member suddenly faints, and the lock needs to be released, a person outside the door can pull out two side plates 20 on the lock seat 1. Then, the person lifts one end of the sliding rod 13 along the second slide groove 17 by hand. The lifted sliding rod 13 drives the half gear 12 to rotate counterclockwise and drives the rack plate 18 to slide downward along the first slide groove 9. When the sliding rod 13 contacts the blocking rod 16, the person detents the rectangular slider 23, so that the rectangular slider 23 drives the blocking rod 16 to move toward the blocking block 14. At this time, the second spring 15 is squeezed by the blocking rod 16 and contracts to generate a large elastic force. At the same time, the person continues to lift the sliding rod 1 along the second slide groove 17. 3. Then the personnel releases the rectangular slider 23. Under the action of the rebound force of the spring 2 15, one end of the spring 2 15 squeezes the blocking rod 16 and moves in the direction of the sliding rod 13 until one end of the blocking rod 16 rests on one end of the sliding rod 13. Then, the personnel holds the handle 1 21 with his left hand, presses the handle 1 21 counterclockwise and drives the base 11 to rotate. The rotating base 11 drives the transmission plate 10 to rotate counterclockwise. One side of the transmission plate 10 squeezes the push pin 8, so that one end of the push pin 8 slides in the positioning block 6. Then, the other end of the push pin 8 drives the lock tongue 3 to completely enter the lock seat 1, realizing the unlocking of the lock body, ensuring that the lock body can be quickly released when it is locked. No professional equipment is required to operate the equipment, thereby avoiding delays in rescue time.
[0060] By setting the half gear 12 and the rack plate 18, it is ensured that the rotation of the half gear 12 drives the rack plate 18 to slide up and down along the slide groove 9 to achieve locking and unlocking, ensure the reliability of the lock body, and avoid the alignment accuracy being reduced and affecting the function of the lock.
[0061] Example 2:
[0062] This embodiment provides a lock body structure, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features: the two ends of the spring 2 15 are tightly welded to the blocking rod 16 and one side of the blocking block 14, respectively; the tail end of the blocking rod 16 is slidingly connected to the blocking block 14; the blocking block 14 and the lock seat 1 are an integrally formed structure.
[0063] Among them, the structural stability of the spring 2 15 is ensured, and the tail end of the blocking rod 16 can be normally received in the blocking block 14, so that the blocking rod 16 can be away from the sliding rod 13, and the structural stability of the lock seat 1 and the blocking block 14 is ensured.
[0064] Example 3:
[0065] This embodiment provides a lock body structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: four cross screws 5 are threadedly installed on the cover plate 4, one end of the cross screw 5 extends into the lock base 1, and one end of the cross screw 5 is threadedly connected to the lock base 1.
[0066] Among them, by providing four cross screws 5, it is ensured that the cover plate 4 can be firmly fixed on the rear side of the lock base 1, ensuring the structural stability of the lock base 1 and the cover plate 4.
[0067] Example 4:
[0068] This embodiment provides a lock body structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the two ends of the spring 7 are tightly welded to the lock tongue 3 and the positioning block 6 respectively, and the half gear 12 is rotatably connected to the lock base 1.
[0069] Among them, the structural stability of the spring 1 7 is ensured to ensure that the half gear 12 can rotate normally in the lock seat 1.
[0070] Example 5:
[0071] This embodiment provides a lock body structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: four cross screws 5 are distributed in a matrix.
[0072] In this case, the structural stability of the cover plate 4 and the lock seat 1 is ensured.
[0073] Example 6:
[0074] This embodiment provides a lock body structure, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the lock tongue 3 is tightly welded to one end of the push-slide pin 8.
[0075] The structure of the lock tongue 3 and the push slide pin 8 is ensured to be stable.
[0076] Working principle: When a person needs to unlock the lock body, he holds the handle 221 with his hand and presses the handle 221 clockwise, so that the handle 221 rotates clockwise, and the clockwise rotating handle 221 drives the base 11 to rotate, and the rotating base 11 drives the transmission plate 10 to rotate clockwise, so that one end of the transmission plate 10 squeezes one end of the push slide pin 8 to slide in the positioning block 6, and then the other end of the push slide pin 8 drives the lock tongue 3 to completely enter the lock seat 1. At the same time, the spring 17 is squeezed by the positioning block 6 and the lock tongue 3, so that the spring 17 contracts and generates a large elastic force. When the person releases the handle 221, under the action of the rebound force of the spring 17, the spring 17 rebounds and stretches and squeezes one end of the lock tongue 3 to move out of the lock seat 1 and pass through the baffle 2;
[0077] When the personnel needs to lock the lock body, and the spring 17 is in a naturally extended state, the personnel rotates the knob 22 clockwise by hand, and the rotating knob 22 drives the half gear 12 to rotate. The rotating half gear 12 drives one end of the sliding rod 13 to slide along the sliding groove 17, and the sliding sliding rod 13 drives the counterweight to move. At the same time, the half gear 12 rotates to drive the rack plate 18 to slide upward along the sliding groove 19. Subsequently, the rack plate 18 moves to the rear side of one end of the push slide pin 8. Because the push slide pin 8 is blocked by the rack plate 18, at this time, the push slide pin 8 cannot drive the lock tongue 3 to move, so that the lock tongue 3 cannot be retracted into the lock seat 1. Under the combined action of gravity and the counterweight, the half gear 12 cannot be reversed, and can continuously keep the rack plate 18 at the rear side of one end of the push slide pin 8, thereby achieving the purpose of locking.
[0078] When a person locks the lock body in the bathroom and an emergency occurs, such as a fire, an earthquake, or a family member suddenly faints, and the lock needs to be released, a person outside the door can pull out two side plates 20 on the lock seat 1. Then, the person lifts one end of the sliding rod 13 along the second slide groove 17 by hand. The lifted sliding rod 13 drives the half gear 12 to rotate counterclockwise and drives the rack plate 18 to slide downward along the first slide groove 9. When the sliding rod 13 contacts the blocking rod 16, the person detents the rectangular slider 23, so that the rectangular slider 23 drives the blocking rod 16 to move toward the blocking block 14. At this time, the second spring 15 is squeezed by the blocking rod 16 and contracts to generate a large elastic force. At the same time, the person continues to lift the sliding rod 1 along the second slide groove 17. 3. Then the personnel releases the rectangular slider 23. Under the action of the rebound force of the spring 2 15, one end of the spring 2 15 squeezes the blocking rod 16 and moves in the direction of the sliding rod 13 until one end of the blocking rod 16 is against one end of the sliding rod 13. Then, the personnel holds the handle 1 21 with his hand, presses the handle 1 21 counterclockwise and drives the base 11 to rotate. The rotating base 11 drives the transmission plate 10 to rotate counterclockwise. One side of the transmission plate 10 squeezes the push pin 8, so that one end of the push pin 8 slides in the positioning block 6. Then, the other end of the push pin 8 drives the lock tongue 3 to completely enter the lock seat 1, thereby unlocking the lock body and ensuring that the lock body can be quickly released when it is locked. No professional equipment is required to operate the equipment, thereby avoiding delays in rescue time.
