Technical Field

[0001] The utility model relates to a rope type locking device and a closing system thereof. Background Art

[0002] The compartment of the cargo transport tool is open, so a compartment cover is required to cover the items in the compartment. The existing shielding system for covering the cargo transport tool compartment generally includes a covering layer for covering the cargo transport tool compartment, the front end of the covering layer is connected to the front frame edge, and the rear end of the covering layer is connected to the rear frame edge; it also includes a driving side frame edge and a passenger side frame edge respectively arranged at the upper ends of the two sides of the cargo transport tool compartment, the two ends of the front frame edge are respectively fixed to the head of the driving side frame edge and the head of the passenger side frame edge, and the tail of the driving side frame edge and the passenger side frame edge is provided with a fixing mechanism. When in use, the rear frame edge is pulled back, and the two ends of the front frame edge are fixed to the fixing mechanism after the covering layer covers the compartment. The general structure of the fixing mechanism is: a card seat is respectively arranged at the tail of the driving side frame edge and the passenger side frame edge, and the card seat has a card slot opening backwards, and the rear frame edge has a card tongue, and the card tongue is inserted into the card slot.

[0003] The existing cargo transport tools are equipped with a box cover and a frame assembly, and the box cover is connected to the left and right side panels of the rear box through the frame assembly, so as to realize the installation of the box cover, and the box cover is formed by a plurality of box cover plates being movably connected to each other, so that the box cover can be turned over and folded for loading cargo. However, the existing box cover and the frame assembly are mostly fixed by screws, bayonet pins or rope binding, and the above fixing methods require a certain amount of time to fix the box cover and the frame assembly to protect against rain or to release the fixation to turn over and fold, which is troublesome to use.

[0004] In order to facilitate the deployment, use and storage of the box cover and frame assembly, existing solutions include the following examples.

[0005] Technical Example 1, referring to patent document CN218934101U, discloses a locking structure for a carriage cover, which is used to cooperate with the frame of the carriage, the carriage cover includes at least two flippable cover units, and the locking structure is fixed to the bottom of the cover unit through a mounting seat, and the locking structure includes: a gear, which is rotatably arranged on the mounting seat; a slide plate, which is slidably arranged on the mounting seat, and the inner side of the slide plate is provided with a tooth portion meshing with the gear; a lock tongue, which is slidably arranged at the bottom of the cover unit, and the lock tongue is connected to the slide plate through a first connecting member; the lock tongue has a locking state in which it extends out of the frame to limit the folding of the cover unit, and the slide plate is driven by the gear to slide, so that the slide plate drives the lock tongue to be retracted into the mounting seat in an unlocked state, thereby increasing the stability of the carriage cover in the unfolded state and facilitating operation.

[0006] Technical Example 2, referring to patent document CN217420838U, discloses a locking structure of a car cover, wherein the car cover comprises at least two flippable cover units, and the locking structure is fixed to the bottom of the cover unit through a mounting seat, and the locking structure comprises: a rotating member, which is rotatably arranged on the mounting seat, and the outer edge of the rotating member extends outward and is provided with at least one connecting portion; a locking tongue, which is slidably arranged at the bottom of the cover unit, and the locking tongue is connected to the connecting portion through a connecting member, and the locking tongue has a locking state in which it extends into the frame to limit the folding of the cover unit, and an unlocking state in which it rotates with the rotating member and detaches from the frame; a first spring, one end of which is pivotally arranged on the mounting seat, and the other end is fixedly connected to the rotating member, and the first spring drives the rotating member to return to the locked state; a limit block, which is arranged on the outside of the rotating member, and the two sides of the limit block are against the rotating member to limit the rotating member in a locked state or an unlocked state, which is convenient for operation and increases the service life of the locking structure.

[0007] Technical Example 3, referring to patent document CN218882690U, discloses a linkage locking mechanism and its covering system, the covering system includes a covering frame, a linkage locking mechanism, and a cover body for covering an open space, the cover body having an unfolded state and a retracted state. The linkage locking mechanism includes a mounting base; an operating member, pivotally connected to the mounting base; a locking member, having a locked position state and an unlocked position state; the locking member can switch between the locked position state and the unlocked position state under the drive of the operating member; a linkage member, connected to the operating member, and forming a transmission match with each locking member; a reset torsion spring, acting on the locking member. The utility model uses the structural characteristics of the reset torsion spring itself, and the working deformation direction of the reset torsion spring itself is adapted to the rotation direction of the operating member and the linkage member, which can better withstand the torsional force, reduce the probability of deformation and damage, and effectively improve the service life and effect.

[0008] It can be clearly seen from the descriptions and drawings of Example 1, Example 2, and Example 3 that all three have the following common defects: 1. Each locking tongue needs to be connected to the slide plate or rotating part through a connecting piece. Multiple locking tongues require multiple connecting pieces, resulting in a larger number of parts and more complicated production and assembly; 2. There is only one operating piece (i.e., handle). In order to realize the drive of multiple locking tongues, it adopts a transmission method of one gear and multiple teeth or a transmission method of one rotating part and multiple connecting parts. In order to meet the requirements of the installation structure, the connecting piece (rope) is not in a working state. It is in an inclined setting; 3. Since the connecting piece (rope) is in an inclined and taut state for a long time, it is easy to cause material fatigue, that is, the connecting piece (rope) is more likely to deform, loosen and other problems, resulting in incomplete movement during subsequent use, and unable to achieve good locking or unlocking functions; 4. The handle is far away from the lock tongue, and the elastic reset force generated by the spring on the lock tongue is greatly lost when it is transmitted to the handle and the slide board, making it difficult to achieve the reset function of the handle and the slide board. Therefore, it is necessary to set a torsion spring separately on the handle or the slide board to achieve the reset of the handle, which leads to an increase in parts and a more complicated structure.

[0009] Therefore, there is an urgent need for a novel locking device and a closing system thereof to solve the above-mentioned deficiencies in the prior art. Summary of the invention

[0027] Furthermore, a limiting guide groove is provided on the groove wall of the accommodating groove, and a guide block is protruding from the lower plate body. The guide block extends into the limiting guide groove and can move along the limiting guide groove.

[0028] The preferred structural scheme of the lock pin assembly in the utility model is that the lock pin assembly includes a lock pin shell with a through hole, and a lock pin body movably inserted into the through hole, the lock pin shell is fixed in the shell assembly, one end of the lock pin body is a locking end, and the other end is a linkage end, the linkage end forms a transmission connection with the linkage rope, and the reset assembly acts on the lock pin body so that the lock pin assembly always has a movement tendency to switch to the locked position state.

[0032] The locking pin assembly is located in the locking pin base;

[0033] The pull-cord lock core member is located in the unlocking housing kit, and the unlocking operating member at least partially extends out of the unlocking housing kit;

[0034] A portion of the linkage rope is located in the rope cover, and the other portion passes through the unlocking housing kit and enters the locking pin base.

[0035] The preferred structural scheme of the unlocking housing kit in the utility model is that the unlocking housing kit includes an unlocking housing base and an unlocking housing cover plate;

[0036] The unlocking housing base and the unlocking housing cover are assembled with each other to form an inner cavity, and the pull cord lock core component is arranged in the inner cavity;

[0037] The unlocking shell cover plate extends toward one side of the lock pin base to form a lock pin cover body. The lock pin base has an upper end opening, and the lock pin cover body covers the upper end opening.

By setting the rope threading space, when the lock pin assembly is in the locked position, the linkage rope can be connected in series between the two lock pin assemblies in a non-inclined straight line, and at this time it is not subject to any force from the unlocking assembly, which is conducive to reducing the pressure on the linkage rope and extending the service life of the linkage rope. In addition, during the unlocking rotation of the pull rope lock core component, one of the contact drive cylinders exerts a force on the linkage rope in the inner right direction, and the other contact drive cylinder exerts a force on the linkage rope in the inner left direction, that is, the forces on the linkage rope in the left and right directions cancel each other out, forming a double inward winding force, so that the effect of winding and collecting the rope is better, more stable and reliable, completely eliminating the slipping phenomenon, and ensuring that the unlocking action is consistent and accurate.

DETAILED DESCRIPTION

[0063] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments are only specific descriptions of the present invention, and their purpose is to allow those skilled in the art to better understand the technical solution of the present invention, and should not be regarded as limiting the present invention.

[0064] In the description of the present invention, it should be noted that the terms "center", "upper", "lower"

[0065] The directions or positional relationships indicated by “left”, “right”, “vertical”, “horizontal”, “inside”, “outside”, etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0066] In the description of the present invention, it should be noted that, 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 components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] Reference Figure 1 to Figure 14 A rope-type locking device comprises: a housing assembly 1 having a lock pin port 131; a lock pin assembly 2, which is assembled at the lock pin port 131 and can move relative to the lock pin port 131, and the lock pin assembly 2 has at least an unlocking position state 2a and a locking position state 2b; a linkage rope 3, which is transmission-connected with the lock pin assembly 2; an unlocking assembly 5, which acts on the lock pin assembly 2 through the linkage rope 3; a reset assembly 4, which acts on the lock pin assembly 2, so that the lock pin assembly 2 always has a movement tendency to switch to the locking position state 2b;

[0068] It is worth mentioning that the unlocking component 5 is different from the structural scheme of the prior art. The unlocking component 5 specifically includes:

[0069] A pull-cord lock core component 51 is movably disposed in the housing assembly 1. The linkage rope 3 passes through the pull-cord lock core component 51. The pull-cord lock core component 51 has a plurality of contact drive cylinders 511. The contact drive cylinders 511 can abut against the linkage rope 3 and drive the linkage rope 3.

[0070] The unlocking operation component 52 is connected to the pull-wire lock core component 51 .

[0071] The above content is the basic structural scheme of the utility model, and its working principle during unlocking operation is: the user controls the unlocking operating component 52 to make the pull-wire lock core component 51 move (preferably rotate) relative to the shell assembly 1, so that the contact driving cylinder 511 on the pull-wire lock core component 51 abuts against the linkage rope 3 and transmits power, and the linkage rope 3 then acts on the locking pin assembly 2 to switch the locking pin assembly 2 from the locked position state 2b to the unlocked position state 2a.

[0072] The working principle of the locking operation is as follows: the user releases the unlocking operating member 52, and the locking pin assembly 2 removes the external force, so that under the reset force of the reset assembly 4 (the force accumulated during the unlocking process), the locking pin assembly 2 switches to the locked position state 2b, and at the same time, the reset assembly 4 also restores the linkage rope 3 and the unlocking assembly 5 to their initial state.

[0073] The utility model adopts a pull cord lock core component 51 with a contact drive column 511, which realizes power transmission with the linkage rope 3 by contact, thereby realizing the unlocking operation of the lock pin assembly 2. It is worth mentioning that the utility model has many advantages. First, the fixed connection method is eliminated. Specifically, the linkage rope 3 does not need to be fixedly connected with the pull cord lock core component 51, which optimizes the production process and reduces the difficulty of assembly; second, a single pull cord lock core component 51 can realize the unlocking operation of multiple lock pin assemblies 2 through a single linkage rope 3; third, when the unlocking operation is not in progress, the unlocking assembly 5 does not apply a force to the linkage rope 3, that is, the linkage rope 3 is in a straight and naturally relaxed state, thereby greatly reducing the product material fatigue of the linkage rope 3, so as to extend the service life of the linkage rope 3 with normal working effect.

[0074] Embodiment 2

[0075] Based on the structure of Example 1, this example provides a preferred implementation scheme, specifically: Figure 2 to Figure 8 The pull cord lock core component 51 has two contact drive cylinders 511, and any one of the contact drive cylinders 511 can contact and drive the linkage rope 3. When two or more contact drive cylinders 511 drive the linkage rope 3, it can effectively prevent the linkage rope 3 and the contact drive cylinders 511 from slipping, and form multiple contact points to balance the force, thereby ensuring the stability of the transmission.

[0076] Furthermore, the pull cord lock core component 51 is in a disc shape, and the two contact drive cylinders 511 are arranged in a non-mirror symmetric manner relative to the linkage rope 3, so that the two contact drive cylinders 511 are staggered along the initial direction of the linkage rope 3 and form a rope threading space 3a, and the linkage rope 3 is at least partially inserted in the rope threading space 3a. Specifically, the structure formed is that the two contact drive cylinders 511 are spaced 180 degrees apart from each other, wherein the right side wall 5111 of one contact drive cylinder 511 contacts the linkage rope 3 to retract the rope on the right side of the pull cord lock core component 51 inwardly; the left side wall 5112 of the other contact drive cylinder 511 contacts the linkage rope 3 to retract the rope on the left side of the pull cord lock core component 51 inwardly, that is, the movement of the pull cord lock core component 51 can simultaneously retract the linkage ropes 3 on both sides inwardly.

[0077] It is worth mentioning that when the lock pin assembly 2 is in the locked position state 2b, the linkage rope 3 can be connected in series between the two lock pin assemblies 2 in a non-inclined straight line, and is not subjected to any force from the unlocking assembly 5 at this time, which is conducive to reducing the pressure on the linkage rope 3 and extending the service life of the linkage rope 3. In addition, during the unlocking rotation of the pull rope lock core component 51, one of the contact drive cylinders 511 exerts a force on the linkage rope 3 along the inner right direction 5a, and the other contact drive cylinder 511 exerts a force on the linkage rope 3 along the inner left direction 5b, that is, the forces on the linkage rope 3 in the left and right directions cancel each other out, forming a double inward winding force, so that the effect of winding and collecting the rope is better, more stable and reliable, and the slippage phenomenon is completely eliminated, ensuring that the unlocking action is consistent and accurate.

[0078] Embodiment 3

[0079] Based on the structure of the second embodiment, further, referring to Figure 1 to Figure 4 , the housing assembly 1 has two lock pin ports 131, each of which is provided with a corresponding lock pin assembly 2; the linkage rope 3 is an integrated rope, and one end of the linkage rope 3 is connected to one of the lock pin assemblies 2, and the other end is connected to another lock pin assembly 2. It should be particularly noted that based on the aforementioned structural setting of this embodiment, what can be achieved in the application scheme is that when the lock pin assembly 2 is in the locked position state 2b, the two lock pin assemblies 2, the rope threading space 3a and the linkage rope 3 are distributed in the same straight line direction 6.

[0080] Application example 1 of this embodiment: two locking pin assemblies 2 are matched with one unlocking assembly 5, wherein it is recommended that one unlocking assembly 5 is located in the middle position of the linkage rope 3, and the unlocking assembly 5 is operated. The unlocking assembly 5 exerts the same force on the linkage ropes 3 on both sides, and can unlock the two locking pin assemblies 2 at the same time through the same linkage rope 3.

[0081] Application example 2 of this embodiment: two locking pin assemblies 2 are matched with two unlocking assemblies 5, wherein it is recommended that the two unlocking assemblies 5 are symmetrically distributed on both sides of the linkage rope 3, and operating any one of the unlocking assemblies 5 can simultaneously unlock the two locking pin assemblies 2 through the same linkage rope 3.

[0082] One of the advantages of Example 2 is that, since there are two unlocking components 5, they are distributed more widely, so the user can more closely contact and operate the unlocking component 5 that is closer to him / herself to achieve unlocking.

[0083] The second advantage is that when operating one unlocking component 5, the points of action on the linkage ropes 3 on both sides are different. Specifically, the linkage rope 3 close to the operated unlocking component 5 will perform a rotational winding action, while the linkage rope 3 close to the unlocking component 5 at the non-operated position will perform a linear retraction action; thus, even during the unlocking process, the linkage rope 3 close to the unlocking component 5 at the non-operated position can always be in a natural relaxation state close to a straight line, and the unlocking component 5 at the corresponding position will not cause resistance to the linkage rope 3 (mainly due to the existence of the rope threading space 3a), and reduce the force loss in the transmission process. Therefore, operating one unlocking component 5 can still easily unlock the two locking pin components 2 at the same time through the same linkage rope 3.

[0084] Embodiment 4

[0085] Based on the structure of any of the above embodiments, this embodiment is a more detailed supplementary structural solution, which is as follows: Figures 4 to 11 The pull cord lock core component 51 includes an upper disk 512 and a lower disk 513, and the contact drive cylinder 511 is fixed between the upper disk 512 and the lower disk 513. Preferably, a support rib 514 is further provided between the upper disk 512 and the lower disk 513 to enhance the structural connection strength and provide better stability.

[0086] The upper disk 512 and the unlocking operating member 52 are connected to each other (preferably through a quadrangular prism 521) so that the two form a fixed connection relationship and can maintain synchronous movement. The housing assembly 1 has a receiving groove 1211, and the lower disk 513 is movably arranged in the receiving groove 1211 (preferably through a circular rotating shaft 5132 to achieve rotational connection). Therefore, when the user drives the unlocking operating member 52, the upper disk 512 and the lower disk 513 can be driven to move (rotate) relative to the receiving groove 1211 (housing assembly 1).

[0087] Furthermore, a limiting guide groove 1212 is provided on the groove wall of the accommodating groove 1211, and a guide block 5131 is convexly provided on the lower plate 513, and the guide block 5131 extends into the limiting guide groove 1212 and can move (rotate) along the limiting guide groove 1212. The angle of the limiting guide groove 1212 is preferably 90°, and can also be 60° or 120°, etc. The angle is not specifically limited here, and is determined according to actual needs. When the guide block 5131 abuts against and limits one side wall of the limiting guide groove 1212, it represents that the locking pin assembly 2 is switched to the locked position state 2b; when the guide block 5131 abuts against and limits the other side wall of the limiting guide groove 1212, it represents that the locking pin assembly 2 is switched to the unlocked position state 2a.

[0088] Embodiment 5

[0089] Based on the structure of any of the above embodiments, this embodiment provides a more preferred structural solution for other related components, as follows:

[0090] 1. Lock pin assembly 2: Refer to Fig.10 , including a lock pin shell 21 with a through hole 211, and a lock pin body 22 movably inserted into the through hole 211, the lock pin shell 21 is fixed in the housing assembly 1, one end of the lock pin body 22 is a locking end 22a, and the other end is a linkage end 22b, the linkage end 22b forms a transmission connection with the linkage rope 3, and the reset assembly 4 acts on the lock pin body 22 so that the lock pin assembly 2 always has a movement tendency to switch to the locked position state 2b.

[0091] Further, the rear edge of the lock pin housing 21 is bent inward to form a limit stop wall 212, and the lock pin body 22 includes a lock pin block 221 and a lock pin pull rod 222 connected to each other, and the lock pin pull rod 222 is connected to the linkage rope 3; the reset component 4 is a spring, and the spring is sleeved on the lock core pull rod, and the spring abuts between the limit stop wall 212 and the lock pin block 221. When resetting, the spring directly acts on the lock pin block 221 to reset it, and the spring indirectly acts on the linkage rope 3 and the unlocking component 5 through the lock pin assembly 2, so that the linkage rope 3 and the unlocking component 5 are reset. Preferably, when there are two (or three or more) unlocking components 5, the unlocking component 5 is arranged at a position close to the lock pin assembly 2, so that the loss can be effectively reduced when the force is transmitted at a close distance, so that the elastic force of a single spring can meet the reset force requirements of the lock pin assembly 2, the linkage rope 3 and the unlocking component 5.

[0092] 2. Shell assembly 1: Reference Figure 1 to Figure 4 The housing assembly 1 includes a lock pin base 11, an unlocking housing assembly 12 and a rope cover 13 arranged in sequence from the outside to the inside. The housing assembly 1 composed of split parts is easier to produce and reduce the difficulty of manufacturing and assembly. In addition, it can be transported in parts during transportation and assembled when needed, so that the split structure is easy to transport and can effectively reduce the probability of damage during transportation.

[0093] More specifically, the locking pin assembly 2 is located in the locking pin base 11; the pull rope lock core component 51 is located in the unlocking shell kit 12, and the unlocking operating component 52 at least partially extends out of the unlocking shell kit 12 to facilitate user operation; a portion of the linkage rope 3 is located in the rope cover 13, and the other portion passes through the unlocking shell kit 12 and enters the locking pin base 11.

[0094] The preferred structural scheme of the unlocking housing kit 12 is that the unlocking housing kit 12 includes an unlocking housing base 121 and an unlocking housing cover 122; the unlocking housing base 121 and the unlocking housing cover 122 are assembled with each other to form an inner cavity 123 with spatial isolation and protection functions, and the pull rope lock core component 51 is arranged in the inner cavity 123; the unlocking housing cover 122 extends toward one side of the lock pin base 11 to form a lock pin cover 1221, and the lock pin base 11 has an upper end opening 111, and the lock pin cover 1221 covers the upper end opening 111. The setting of the upper end opening 111 is conducive to the installation of the linkage rope 3. After installation, the linkage rope 3 is isolated from the outside through the cover of the lock pin cover 1221 to provide a protection function.

[0095] Embodiment 6

[0096] Reference Figure 11 to Figure 14 The present invention further provides a closing system 7, comprising a frame 71 having an open space 711, and a closing cover 72 for shielding the open space 711, wherein the closing cover 72 has an unfolded state 7a and a retracted state 7b; the closing cover 72 is provided with a rope-type locking device 73 as described above;

[0097] When the locking pin assembly 2 is in the locked position state 2b, the locking pin assembly 2 forms a limit fit with the frame 71 to limit the movement of the closed cover body 72 and keep it in the expanded state 7a. At this time, the closed cover body 72 continues to cover the open space 711.

[0098] When the locking pin assembly 2 is in the unlocked position state 2a, the locking pin assembly 2 and the frame 71 are staggered with each other, and the closing cover body 72 can move freely to switch from the unfolded state 7a to the stored state 7b, at which time the released open space 711 is released.

[0099] It is worth mentioning that the closing system 7 is applied to freight vehicles (such as pickup trucks), and the open space 711 is a rear cargo space that can be used to prevent cargo from being put in. The closing system 7 switches to the expanded state 7a to cover the rear cargo space and provide effective protection against water, dust, theft, etc.; when cargo needs to be placed or taken out or the cargo is large in size, the closing system 7 switches to the stored state 7b to release the rear cargo space.

[0100] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0101] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
