Description

Technical Field

[0001] This utility model relates to the field of railing technology, and in particular to folding railings. Background Technology

[0002] Folding cribs, baby safety railings, playpens, and other baby and toddler products are primarily designed for babies aged 0 to 6 years, aiming to provide them with a safe and comfortable space for play and short rests. They are also foldable for easy transport when out and about; existing folding mechanisms typically utilize the folding of the railings to meet different folding needs.

[0003] Existing folding railings have certain drawbacks in use. First, in order to meet the overall strength requirements of the railing, it is inconvenient to operate when folding and cannot be folded quickly. Second, in order to meet the requirements of quick folding, the overall strength of the folding railing cannot be guaranteed during use. In other words, it is impossible to achieve both the strength of the railing and quick folding at the same time, which has a certain impact on people's use. Therefore, we propose folding railings. Utility Model Content

[0004] The main purpose of this utility model is to provide a folding railing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A folding railing, including a fixing frame, wherein two fixing shafts are provided at the middle position of the fixing frame;

[0007] The fixed frame has two upper rotating shaft reciprocating slots through it, and the two upper rotating shaft reciprocating slots are located on both sides of the two fixed shafts respectively. An upper rotating shaft is inserted into each of the two upper rotating shaft reciprocating slots. A railing connector is installed on one side of each upper rotating shaft, and an upper railing is fixedly installed on one side of each of the two railing connectors.

[0008] Each of the railing connectors has a fixing groove at one end, and the two fixing grooves are respectively matched with two fixing shafts.

[0009] Furthermore, the fixing frame is configured in two layers, connected by a top plate in the middle, and the fixing frame is integrally formed.

[0010] Furthermore, a synchronous steering groove is provided through the fixed frame located at the lower end of the two upper rotating shaft reciprocating grooves, and a synchronous center groove is provided at the middle position of the fixed frame, and the two synchronous steering grooves are symmetrically arranged about the synchronous center groove.

[0011] Furthermore, a synchronous steering shaft is movably installed inside each of the two synchronous steering slots, and the synchronous steering shaft is provided through the through hole on the railing connector. A synchronous connecting piece is provided on each of the two synchronous steering shafts, and the two synchronous connecting pieces are located outside the fixed frame. The other ends of the two synchronous connecting pieces overlap and are provided through a synchronous connecting shaft, which is also provided through the synchronous center slot.

[0012] Furthermore, the lower end of the fixing frame is provided with a second through hole and an auxiliary groove on both sides, and the second through hole is located on one side of the auxiliary groove.

[0013] Furthermore, a lower rotating shaft is inserted into the interior of each of the two second through holes, and a lower railing is mounted on the lower rotating shaft. A reinforcing shaft is inserted into the interior of each of the two auxiliary slots, and the reinforcing shaft is inserted into the tail end of the lower railing.

[0014] Furthermore, mounting holes are provided at the other ends of both upper railings and both lower railings, and the two mounting holes on the same side are mounted on the same connecting plate via a connecting shaft.

[0015] Furthermore, the fixing frame has two first through holes, and the two fixing shafts are disposed through the two first through holes. One end of the railing connector is provided with a connecting nail, and one end of the upper railing is inserted into the railing connector and fixed by the connecting nail.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model, through the setting of a fixed groove and a fixed shaft, can achieve locking in the flat state of the railing. Only by pulling the upper railing and causing the fixed groove to disengage from the fixed shaft can the folding operation be completed, which better ensures the stability of the railing in the flat state and prevents folding caused by accidental contact. At the same time, the upper rotating shaft, as the rotation center shaft, can be matched with the upper rotating shaft reciprocating groove to meet the locking and unlocking states, better satisfying the locking operation.

[0018] 2. This utility model, through the provision of a synchronous steering shaft, a synchronous connecting piece, and a synchronous connecting shaft, as well as a synchronous steering groove and a synchronous center groove, enables the upper railings on both sides to form a synchronous linkage mechanism. This design allows the upper railings on both sides to fold simultaneously. During folding, the two railing connectors simultaneously pull the synchronous connecting piece installed on it to move along the synchronous steering groove. At the same time, the synchronous connecting piece drives the synchronous connecting shaft to move upward in the synchronous center groove. At this time, due to the limiting effect of the synchronous center groove, the upper railings on both sides are folded synchronously.

[0019] 3. This utility model, through the addition of auxiliary grooves and reinforcing shafts, increases the connection points between the lower railing and the fixed frame, thereby enhancing the stability of the lower railing installation. Based on the lower rotating shaft installed at one end of the lower railing, a reinforcing shaft and an auxiliary groove that coordinates with the movement of the reinforcing shaft are also provided at the end of the lower railing, i.e., the rear end of the lower rotating shaft. This adds a force-bearing point to the lower railing during rotation or use, and the movement of this force-bearing point has a certain trajectory, restricting it to the reinforcing shaft. This better satisfies the stability of the lower railing during rotation or use and better ensures the strength of the folding railing.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figure 1-8 As shown, the folding railing includes a fixing frame 3, and two fixing shafts 6 are provided in the middle of the fixing frame 3;

[0032] Two upper rotating shaft reciprocating grooves 4 are opened through the fixed frame 3, and the two upper rotating shaft reciprocating grooves 4 are located on both sides of the two fixed shafts 6 respectively. An upper rotating shaft 5 is inserted into the two upper rotating shaft reciprocating grooves 4. A railing connector 2 is installed on one side of each upper rotating shaft 5, and an upper railing 1 is fixedly installed on one side of each railing connector 2.

[0033] Each railing connector 2 has a fixing groove 11 at one end, and the two fixing grooves 11 are respectively matched with two fixing shafts 6.

[0034] In this embodiment, the railing connector 2 can lock the upper railing 1 in its flattened state. It should be noted that the shape of the railing connector 2 is as follows: Figure 2 As shown, the lower part of the railing connector 2 is semi-circular. The fixing groove 11 at one end is engaged with the fixing shaft 6 in the flat state. When folding is required, the upper railing 1 is pulled. At this time, the upper rotating shaft 5 moves horizontally outward in the upper rotating shaft reciprocating groove 4, so that the fixing groove 11 is disengaged from the fixing shaft 6. Then, the upper railing 1 can be folded by rotating it upward.

[0035] The fixing frame 3 is a two-layer structure connected by a top plate in the middle, and the fixing frame 3 is integrally formed. The overall structure of this utility model is completely identical in shape and structure when viewed from the front and rear views. The description only describes the part seen from the front view; the rear view is exactly the same as the front view and will not be described again here.

[0036] Synchronous steering grooves 18 are provided through the fixed frame 3 located at the lower end of the two upper rotating shaft reciprocating grooves 4, and a synchronous center groove 15 is provided in the middle of the fixed frame 3, and the two synchronous steering grooves 18 are symmetrically arranged about the synchronous center groove 15.

[0037] Synchronous steering shafts 12 are movably installed inside both synchronous steering slots 18, and the synchronous steering shafts 12 pass through the through holes on the railing connector 2. Synchronous connecting pieces 13 are provided on both synchronous steering shafts 12, and both synchronous connecting pieces 13 are located outside the fixed frame 3. The other ends of the two synchronous connecting pieces 13 are overlapped and connected, and a synchronous connecting shaft 14 is provided through them. At the same time, the synchronous connecting shaft 14 passes through the synchronous center slot 15.

[0038] This utility model, through the arrangement of a synchronous steering shaft 12, synchronous connecting pieces 13 and synchronous connecting shaft 14, as well as a synchronous steering groove 18 and a synchronous center groove 15, enables the upper railings 1 on both sides to form a synchronous linkage mechanism. This design allows the upper railings 1 on both sides to fold synchronously. During folding, the upper railing 1 moves outward, the fixing groove 11 disengages from the fixing shaft 6, and the railing connector pulls the synchronous connecting pieces through the steering connecting shaft. As a result, the synchronous connecting pieces drive the synchronous connecting shaft 14 to move upward within the synchronous center groove 15. Since the two synchronous connecting pieces 13 overlap at one end and are penetrated by the synchronous connecting shaft 14, when the synchronous connecting shaft 14 moves upward, the two synchronous connecting pieces 13 move synchronously along the synchronous steering groove 18. This results in the synchronous steering shaft 12, which is installed on the two synchronous connecting pieces 13, also moving in the synchronous steering groove 18. Ultimately, this enables the upper railings 1 installed on the railing connector 2 to fold synchronously.

[0039] The lower end of the fixing bracket 3 is provided with a second through hole 17 and an auxiliary groove 7 on both sides, and the second through hole 17 is located on one side of the auxiliary groove 7.

[0040] It should be noted that existing folding rail installations all use a single shaft, which causes the shaft to wobble under torque, leading to instability during rotation or use. In this design, in addition to a lower rotating shaft 9 installed at one end of the lower rail 10, a reinforcing shaft 8 and an auxiliary groove 7 that moves in coordination with the reinforcing shaft 8 are also provided at the end of the lower rail 10, i.e., the rear end of the lower rotating shaft 9. This adds a stress point to the lower rail 10 during rotation or use, and the movement of this stress point has a certain trajectory, restricting it to the reinforcing shaft 8. This better ensures the stability of the lower rail 10 during rotation or use and better guarantees the strength of the folding rail.

[0041] Both second through holes 17 have a lower rotating shaft 9 inserted inside, and a lower railing 10 is installed on the lower rotating shaft 9. Both auxiliary slots 7 have a reinforcing shaft 8 inserted inside, and the reinforcing shaft 8 is inserted at the tail end of the lower railing 10.

[0042] Each of the two upper railings 1 and the two lower railings 10 has a mounting hole at one end, and the two mounting holes on the same side are mounted on the same connecting plate 20 through a connecting shaft.

[0043] Specifically, during folding, the upper railing 1 can be folded by operating it, such as... Figure 8 As shown, the lower railing 10 can only be linked with the upper railing 1 when the upper railing 1 is folded, provided that the lower railing 10 is installed on the same connecting plate 20 as the upper railing 1. The design of the lower railing 10 better ensures the strength of the railing during use.

[0044] The fixing frame 3 has two first through holes 16, and two fixing shafts 6 are inserted through the two first through holes 16. One end of the railing connector 2 is provided with a connecting nail 19, and one end of the upper railing 1 is inserted into the railing connector 2 and fixed by the connecting nail 19.

[0045] It should be noted that this utility model is a folding railing, such as... Figure 1 As shown, this is the flattened state of the folding railing. At the same time, both upper railings 1 are pushed inward a certain distance, pushing their respective upper rotating shafts 5 to the innermost side of the upper rotating shaft reciprocating groove 4, thus locking the fixing groove 11 onto the fixing shaft 6 and effectively preventing folding tendency due to external shaking. The two lower railings 10 are also flattened along with the upper railings 1 under the drive of the connecting plate 20. At this time, the reinforcing shaft 8 rotates to the same horizontal line position as the lower rotating shaft 9.

[0046] When this folding railing needs to be folded, that is, when it needs to be folded to such a degree... Figure 6 In the indicated state, pull the left upper rail 1 to the left and the right upper rail 1 to the right, causing the two fixing grooves 11 to disengage from their respective fixing shafts 6. At this time, the upper rotating shafts 5 will move a certain distance in their respective directions, satisfying the control of the fixing grooves 11 disengaging from the fixing shafts 6. Then, rotate the two upper rails 1 upward. At this time, under the limit control of the synchronous steering shaft 12, synchronous connecting piece 13 and synchronous connecting shaft 14, as well as the set synchronous steering groove 18 and synchronous center groove 15, the upper rails 1 on both sides can be folded synchronously. During folding, the two rail connectors 2 simultaneously pull the synchronous connecting piece 13 installed on it to move along the synchronous steering groove 18. At the same time, the synchronous connecting piece 13 carries the synchronous connecting shaft 14 to move upward in the synchronous center groove 15, thus realizing the synchronous folding of the upper rails 1 on both sides. The two lower rails 10 at the bottom will also move upward under the drive of the connecting plate 20. The set reinforcing shaft 8 and auxiliary groove 7 can increase the connection points between the lower rails 10 and the fixing frame 3, increasing the stability of the installation of the lower rails 10. After folding, as shown Figure 6 As shown, the two upper railings 1 are close to the top plate of the fixed frame 3, and the two lower railings 10 are folded to the middle position of the two layers of fixed frame 3, which can greatly save the space occupied after folding.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
