Description

Technical Field

[0001] This utility model relates to the field of furniture and home furnishings, specifically to a quick-locking device and a bed. Background Technology

[0002] Many existing bed frames have retainers at the rear or sides, primarily to prevent the mattress from slipping and to prevent accidental falls due to weakness, confusion, or rolling over, thus reducing the risk of injury. Common retainer locking methods include threaded fixing, ordinary pin fixing, or snap-locking. While all three locking methods are simple, they each have drawbacks. For example, threaded locking tends to loosen over time; ordinary pin fixing is difficult for users to operate blindly, and the gap fit between the retainer and the hole can cause resonance and noise during vibration massage; snap-locking is more expensive. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a quick locking device and bed, which has the advantages of simple structure, easy operation, and the ability to avoid resonance between the stop bar and the bed frame.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a quick locking device for locking a stop bar on a bed frame, comprising: an elastic reset member assembled in the bed frame, a pin body assembled in the bed frame, a pin handle with one end fixed to the pin body and the other end protruding outside the bed frame, and a mounting base assembled on the bed frame.

[0005] One side of the stop bar is inserted into the bed frame and has a through hole for inserting one end of the pin body;

[0006] One end of the elastic reset member abuts against the mounting base, and the other end abuts against the pin body.

[0007] The present invention further comprises: an insertion portion for engaging with the through hole and a clamping portion connected to the insertion portion; the insertion portion and the clamping portion are cylindrical; the outer diameter of the clamping portion is larger than the outer diameter of the insertion portion and larger than the diameter of the through hole. When the insertion portion is inserted into the through hole, one side of the clamping portion abuts against the outer wall of the stop rod located on the periphery of the through hole.

[0008] The present invention is further provided that the axis of the elastic reset member, the axis of the pin body, and the axis of the through hole are all located on the same horizontal line.

[0009] The present invention further provides that the mounting base includes: a fixing plate with one end placed inside the bed frame and a guide shaft with one end mounted on the fixing plate and the other end extending horizontally toward the through hole;

[0010] The pin body and the elastic reset component are movably sleeved on the outer periphery of the guide shaft;

[0011] One end of the elastic reset member abuts against the fixing plate, and the other end abuts against the pin body.

[0012] The present invention further provides that the fixing plate includes: a mounting part fixedly installed on the outer wall of the bed frame and an extension part with one end perpendicular to the mounting part and the other end passing through the bed frame and protruding from the outer side of the bed frame; the extension part is for assembling the guide shaft.

[0013] To achieve the above objectives, another technical solution adopted by this utility model is: a bed, comprising: a bed frame with a hollow structure, a stop bar assembled at the end of the bed frame, and a quick locking device assembled on the end of the bed frame and used to lock the stop bar, as described above.

[0014] The present invention further includes a first insertion hole on the top side of the end of the bed frame for inserting one side of the stop bar; a second insertion hole corresponding to the first insertion hole is provided on the bottom side of the end of the bed frame; both the first insertion hole and the second insertion hole are connected to the hollow structure.

[0015] The present invention further provides that the top and bottom sides of the bed frame end are respectively provided with a first limiting hole and a second limiting hole for limiting the mounting seat; the first limiting hole and the second limiting hole are both connected to the hollow structure.

[0016] The present invention further provides that the bottom side of the end of the bed frame is provided with a guide channel that connects the second insertion hole and the second limiting hole and allows the pin handle to move.

[0017] The present invention further provides that the bottom side of the bed frame at the foot of the bed is provided with a limiting groove that communicates with the guide channel and is used to restrict the movement of the pin handle; when the pin handle is placed into the limiting groove, the pin body is disengaged from the through hole and the stop bar is in the unlocked state.

[0018] The beneficial effects of this utility model after adopting the above technical solution are as follows: In this utility model, the user unlocks the latch body through the latch handle exposed outside the bed frame. Since one end of the elastic reset member abuts against the mounting base and the other end abuts against the latch body, under the elastic force of the elastic reset member, one end of the latch body is pushed into the stop bar through hole, ensuring that the stop bar is stably locked. In addition, the elastic reset member always abuts against the mounting base at one end and against the latch body at the other end, and the elastic pressing of the elastic reset member can also prevent the stop bar from resonating with the bed frame and causing abnormal noise. The overall structure of this quick locking device is simple, and the operation of locking the stop bar is convenient. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0038] This embodiment relates to a quick locking device, see reference... Figures 1-11The system includes: a resilient reset element 100, a pin body 200, a pin handle 300, and a mounting base 400. The resilient reset element 100 is installed inside the bed frame 500, the pin body 200 is installed inside the bed frame 500, one end of the pin handle 300 is fixed to the pin body 200, and the other end protrudes outside the bed frame 500. The mounting base 400 is installed on the bed frame 500. One side of the stop bar 600 is inserted into the bed frame 500 and has a through hole 610 for inserting one end of the pin body 200. One end of the resilient reset element 100 abuts against the mounting base 400, and the other end abuts against the pin body 200. Specifically, the user unlocks the pin body 200 using the pin handle 300 protruding outside the bed frame 500. Since one end of the elastic reset member 100 abuts against the mounting base 400 and the other end abuts against the pin body 200, under the elastic force of the elastic reset member 100, one end of the pin body 200 is pushed into the through hole 610 of the stop rod 600, ensuring that the stop rod 600 is stably locked. In addition, the elastic reset member 100 always abuts against the mounting base 400 at one end and against the pin body 200 at the other end. The elastic force of the elastic reset member 100 can also prevent the stop rod 600 from resonating with the bed frame 500 and causing abnormal noise. This quick locking device has a simple overall structure and the operation of locking the stop rod 600 is simple. In this embodiment, the elastic reset member 100 is in a compressed state, and the elastic force of the elastic reset member 100 is directed towards the through hole 610 of the stop rod 600. The elastic force of the elastic reset member 100 is the pushing force on the pin body 200. In this embodiment, the elastic reset member 100 is set as a spring. In some embodiments, the elastic reset member 100 can also be set as a spring block.

[0039] In this embodiment, refer to Figures 8-11The pin body 200 includes an insertion portion 210 and a retaining portion 220. The insertion portion 210 mates with the through hole 610, and the retaining portion 220 is connected to the insertion portion 210. Both the insertion portion 210 and the retaining portion 220 are cylindrical. The outer diameter of the retaining portion 220 is larger than the outer diameter of the insertion portion 210 and also larger than the diameter of the through hole 610. When the insertion portion 210 is inserted into the through hole 610, one side of the retaining portion 220 abuts against the outer wall of the stop rod 600 located around the through hole 610. Specifically, the insertion portion 210 and the retaining portion 220 are integrally formed, and their axes are on the same straight line. When it is necessary to lock the stop bar 600, the elastic force of the elastic reset member 100 pushes the entire pin body 200 to slide toward the through hole 610 of the stop bar 600. The insertion portion 210 of the pin body 200 is inserted into the through hole 610. One end of the elastic reset member 100 abuts against the extension portion 412, and the other end abuts against the side of the clamping portion 220 of the pin body 200 facing the elastic reset member 100. The side of the clamping portion 220 near the stop bar 600 abuts against the outer wall of the stop bar 600 located around the through hole 610. This not only locks the stop bar 600 onto the bed frame 500, but also prevents the stop bar 600 from resonating with the bed frame 500 and causing abnormal noise. In some embodiments, the free end of the insertion portion 210 is provided with a guide slope to facilitate insertion into the through hole 610.

[0040] Furthermore, the axis of the elastic reset member 100, the axis of the pin body 200, and the axis of the through hole 610 are all located on the same horizontal line (see reference). Figure 8 as well as Figure 11 (Horizontal lines A and B in the diagram) to ensure that the insertion part 210 of the pin body 200 can be smoothly inserted into the through hole 610 under the elastic force of the elastic reset member 100.

[0041] Furthermore, referring to Figures 1-3 as well as Figure 8 The mounting base 400 includes a fixing plate 410 and a guide shaft 420. One end of the fixing plate 410 is placed inside the bed frame 500, and one end of the guide shaft 420 is mounted on the fixing plate 410, while the other end extends horizontally toward the through hole 610. A pin body 200 and a resilient reset member 100 are movably sleeved on the outer periphery of the guide shaft 420; one end of the resilient reset member 100 abuts against the fixing plate 410, and the other end abuts against the pin body 200. The guide shaft 420 is used to restrict the axial movement of the pin body 200 and the resilient reset member 100, preventing displacement of the pin body 200 and the resilient reset member 100, which would prevent one end of the pin body 200 from being smoothly inserted into the through hole 610 of the stop bar 600. (Refer to...) Figures 6-11 Specifically, the axis of the guide shaft 420, the axis of the elastic reset member 100, the axis of the pin body 200, and the axis of the through hole 610 are all located on the same horizontal line (refer to...). Figure 8 as well as Figure 11(Horizontal lines A and B in the diagram) to ensure that the insertion part 210 of the pin body 200 can be smoothly inserted into the through hole 610 under the elastic force of the elastic reset member 100.

[0042] Furthermore, the fixing plate 410 is L-shaped. The fixing plate 410 includes a mounting part 411 and an extension part 412. The mounting part 411 is fixedly mounted on the outer wall of the bed frame 500, and one end of the extension part 412 is perpendicular to one end of the mounting part 411, while the other end passes through the inside of the bed frame 500 and protrudes from the outside of the bed frame 500; the extension part 412 is used for the assembly of the guide shaft 420. The mounting part 411 is directly fixed to the outer wall of the bed frame 500 to achieve a stable assembly with the bed frame 500; the extension part 412 passes through the inside of the bed frame 500 to facilitate the installation of the guide shaft 420. Specifically, the elastic reset member 100 is movably sleeved on the outer periphery of the guide shaft 420 and is located between the extension part 412 and the pin body 200. One end of the elastic reset member 100 abuts against the side of the extension part 412 facing the pin body 200, and the other end abuts against the side of the pin body 200 facing the extension part 412.

[0043] This embodiment also relates to a bed, as shown in the following figure. Figures 6-8 The system includes a bed frame 500, a retaining bar 600, and a quick-locking device as described above. The bed frame 500 has a hollow structure 510. The retaining bar 600 is mounted on the foot end of the bed frame 500, and the quick-locking device is mounted on the foot end of the bed frame 500 and is used to lock the retaining bar 600. The retaining bar 600 is used to prevent the mattress from slipping. In this embodiment, two quick-locking devices are provided, one for locking both ends of the retaining bar 600.

[0044] Furthermore, referring to Figure 9 as well as Figures 12-15 The bed frame 500 has a first insertion hole 520 on the top side of the tail end for inserting one side of the stop bar 600; the bed frame 500 has a second insertion hole 530 on the bottom side of the tail end corresponding to the first insertion hole 520; both the first insertion hole 520 and the second insertion hole 530 are connected to the hollow structure 510. There are two of each of the first insertion hole 520 and the second insertion hole 530 to facilitate the insertion of both ends of the stop bar 600.

[0045] Furthermore, referring to Figure 9 as well as Figures 12-15The bed frame 500 has a first limiting hole 540 and a second limiting hole 550 on the top and bottom sides of the tail end, respectively, for limiting the mounting base 400. Both the first limiting hole 540 and the second limiting hole 550 are connected to the hollow structure 510. Correspondingly, there are two of each of the first limiting hole 540 and the second limiting hole 550. In this embodiment, the bottom side of the tail end of the bed frame 500 has a guide channel 560 that connects the second insertion hole 530 and the second limiting hole 550 and allows the pin handle 300 to move. Specifically, there are also two guide channels 560. The guide channels 560 restrict the movement trajectory of the pin handle 300, ensuring that the pin handle 300 can only move axially (in the direction of sliding of the pin body 200), and avoiding jamming of the pin body 200 during sliding due to the offset of the pin handle 300.

[0046] In this embodiment, refer to Figure 5 as well as Figures 12-15 The bottom side of the bed frame 500 at the end of the bed is also provided with a limiting groove 570 that communicates with the guide channel 560 and is used to restrict the movement of the pin handle 300. When the pin handle 300 is placed into the limiting groove 570, the pin body 200 is disengaged from the through hole 610 and the stop bar 600 is in the unlocked state. At this time, the stop bar 600 can be pulled out from the first insertion hole 520 and the second insertion hole 530 so as to remove, replace or clean the stop bar 600. When the stop lever 600 is inserted into the first insertion hole 520 and the second insertion hole 530, after the pin handle 300 is moved out of the limiting groove 570 and placed into the guide channel 560, under the elastic pushing action of the elastic reset member 100, the pin body 200 slides axially toward the through hole 610 of the stop lever 600 until the insertion part 210 of the pin body 200 is inserted into the through hole 610. One end of the elastic reset member 100 abuts against the extension part 412, and the other end abuts against the abutting part 220 of the pin body 200. The abutting part 220 abuts against the outer wall of the stop lever 600 located on the periphery of the through hole 610, thus finally locking the stop lever 600. The whole process is simple to operate. After moving the pin handle 300 out of the limiting groove 570 and placing it into the guide channel 560, the locking of the stop lever 600 can be completed blindly.

[0047] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
