Description

Technical Field

[0001] This utility model relates to the field of fence technology, and in particular to a fence connection structure. Background Technology

[0002] Fences, as a common type of isolation, protection, or decorative structure, are widely used in various settings such as courtyards, gardens, balconies, public areas, and temporary isolation zones. Common fences are typically composed of multiple railings (posts, crossbars, etc.) connected together.

[0003] In existing technologies, the connection methods between fence railings typically include the following:

[0004] 1. Fixed connection: such as welding, riveting, or using bolts and nuts for rigid fixation. Although this method results in a sturdy structure, once installed, the relative positions and angles between the railings are fixed, making it impossible to adjust or change the overall shape of the fence according to actual needs, thus lacking flexibility.

[0005] 2. Simple Hinged Connection: Some fences use simple hinge structures to connect adjacent railings, allowing them to rotate relative to each other. However, these simple hinges usually lack an effective locking mechanism. They often require additional fasteners (such as pins or clamps) or tools for reinforcement, making the process cumbersome and inconvenient.

[0006] 3. Complex Adjustable Connectors: Some relatively complex adjustable connectors exist on the market, which may have locking functions. However, these connectors are usually structurally complex, and their unlocking and locking operations are often not intuitive or convenient, resulting in a poor user experience and low efficiency when adjusting the railing angle or changing the shape of the fence. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a connection structure for a fence, which has the characteristics that the angle between the railings can be adjusted and the adjustment process is relatively simple and convenient.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0009] A fence connection structure includes a plurality of railings and a connecting assembly that hinges two adjacent railings together; the connecting assembly includes a connector, two inserts are provided in the left and right directions at the lower end of the connector, and a hinge joint is provided at the end of the railing that is hinged to the connecting assembly, and a slot is provided on the hinge joint.

[0010] The two inserts of the connector can respectively mate with slots on two different railings, and when the connector mates with the slot, the relative position of the hinge and the connector is locked.

[0011] The insert has a first mating tooth on its peripheral wall and a second mating tooth on its inner wall, so the first mating tooth can engage with the second mating tooth to lock it in place.

[0012] The connecting assembly includes a support rod and a connecting seat mounted on the upper end of the support rod, on which two hinge joints of different railings are rotatably connected.

[0013] The connector also includes a fixing member, which includes two fixing studs. The fixing studs pass through the middle of the slot to the connector seat and are connected and fixed to the connector seat.

[0014] The connector includes a pressure-lifting body disposed outside the fixing component and capable of moving up and down, and the insert is disposed at the lower end of the pressure-lifting body.

[0015] An elastic element is provided between the fixing component and the lifting body. When no external force is applied, the elastic element stores elastic potential energy that pushes the lifting body downward to make the insert and slot fit together.

[0016] The elastic element is a spring, which is respectively sleeved on the two fixing studs of the fixing element. The upper end of the spring abuts against the fixing element, and the lower end abuts against the lower end of the lifting body.

[0017] The pressure-lifting body is a shell with an internal space. The front and rear inner walls of the pressure-lifting body are respectively provided with a first locking groove and a second locking groove from top to bottom. The front and rear sides of the fixing member are provided with locking protrusions that can cooperate with the first locking groove and the second locking groove.

[0018] A guide slope is provided between the first and second card slots, and the area formed between the two guide slopes gradually narrows from top to bottom.

[0019] The fixing stud and the connecting seat are connected and fixed by screws. The lifting body is also provided with a cover, and a connecting stud is also provided under the cover. The connecting stud extends to the lower end of the lifting body and is also connected and fixed from bottom to top by screws.

[0020] The railing includes two horizontal bars, one above the other, and several vertical bars between the horizontal bars. The lower horizontal bar is also provided with feet. The railing at the end of the fence is connected to a support member.

[0021] The beneficial effects of this utility model are:

[0022] 1. This fence consists of several interlocking railings, each connected to the others via connecting components. Connectors on these components allow for easy control of the movement and locking of the railings; operation is simply a matter of lifting or pressing down the connector. This allows the fence to be configured in various shapes, such as straight or square, suitable for different scenarios. Furthermore, the transformation process is quick and easy, reducing setup time.

[0023] 2. The connectors mate with hinges on two adjacent railings. Specifically, when the insert with the first mating tooth disengages from the slot with the second mating tooth, the adjacent railings can be freely adjusted at multiple angles; when the mating teeth engage, the adjacent railings are locked in a fixed state. Compared to traditional locking methods (pins, clamps), this design is more convenient and reliable.

[0024] 3. The connector includes a lifting body and a spring between the lifting body and the fixing part. In the locked state, the spring continuously provides downward pressure, so that the insert and the slot are in a relatively stable locked state, which further increases the connection stability between the railings. When unlocking is required, simply lift the lifting body to overcome the spring force, and the insert and the slot can be separated to release the locked state. No tools or auxiliary parts are required throughout the process, making the operation simple and convenient and significantly improving the adjustment efficiency.

[0025] 4. The inner wall of the lifting body is equipped with a first locking groove and a second locking groove. When locked, the locking protrusion of the fixing component engages with the second locking groove, further improving the stability of the locked state. When unlocking, the lifting body is lifted, and the second locking groove engages with the locking protrusion. At this time, the spring tends to pull the lifting body downward, but it is insufficient to overcome the deformation force of the locking protrusion and the second locking groove. Therefore, after the lifting body is lifted to unlock, the unlocked state is maintained without external force, allowing users to freely adjust the angle or position of adjacent railings, which is quite convenient. When locking is required after adjustment, simply press the lifting body. The fixing component moves downward relative to the lifting body, and the locking protrusion of the fixing component engages again with the first locking groove along the guide slope, completing the locking. On the other hand, the design of the first locking groove, the second locking groove, and the locking protrusion also improves the user's feel during adjustment. The feedback for unlocking and locking is more obvious, avoiding misoperation due to improper adjustment and improving the intuitiveness of operation. Attached Figure Description

[0034] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0035] Reference Figure 1-3 This utility model proposes a fence connection structure, including several railings 1 and a connection component 2 that hinges two adjacent railings 1 together; the connection component 2 includes a connector 3, and two inserts 300 are provided in the left and right directions at the lower end of the connector 3. A hinge joint 10 is provided at the end of the railing 1 that is hinged to the connection component 2, and a slot 100 is provided on the hinge joint 10.

[0036] The two inserts 300 of the connector 3 can respectively mate with the slots 100 on two different railings 1, and when the connector 3 mates with the slots 100, the relative position of the hinge joint 10 and the connector 3 is locked.

[0037] Specifically, the fence consists of several railings 1 that are hinged together. Each railing 1 is connected to the others via a connecting component 2. The connector 3 on the connecting component 2 allows for convenient control of the movement and locking state between two railings 1. Operation is achieved simply by lifting or pressing down the connector 3. This allows the fence to be transformed into various forms, such as a straight fence or a square fence, suitable for various scenarios. Moreover, the transformation process is convenient and quick, shortening the deployment time.

[0038] Reference Figure 3The insert 300 has a first mating tooth 61 on its peripheral wall and a second mating tooth 60 on its inner wall. Therefore, the first mating tooth 61 can engage with the second mating tooth 60 to lock the insert.

[0039] Reference Figure 2 and Figure 3 The connecting component 2 includes a support rod 22 and a connecting seat 21 mounted on the upper end of the support rod 22. Two hinge joints 10 of different railings 1 are rotatably connected to the connecting seat 21.

[0040] Reference Figure 3 The connector 3 also includes a fixing member 31, which includes two fixing studs 310. The fixing studs 310 pass through the middle of the slot 100 to the connector 21 and are connected and fixed to the connector 21.

[0041] The connector 3 includes a lifting body 30 disposed outside the fixing member 31 and capable of moving up and down, and a tube 300 disposed at the lower end of the lifting body 30.

[0042] Specifically, the connector 3 engages with the hinge joints 10 on two adjacent railings 1. Specifically, when the insert 300 with the first engaging tooth 61 disengages from the slot 100 with the second engaging tooth 60, the adjacent railings 1 can be freely adjusted at multiple angles; when the engaging teeth engage, the adjacent railings 1 are locked in a fixed state. Compared to traditional locking methods (pins, clamps), this design is more convenient and reliable.

[0043] Reference Figure 3-5 An elastic element 32 is provided between the fixing element 31 and the lifting body 30. When there is no external force, the elastic element 32 stores elastic potential energy that pushes the lifting body 30 downward so that the insert 300 and the slot 100 are engaged.

[0044] The elastic element 32 is a spring, which is respectively sleeved on the two fixing studs 310 of the fixing element 31. The upper end of the spring abuts against the fixing element 31, and the lower end abuts against the lower end of the lifting body 30.

[0045] Specifically, the connector includes a lifting body 30, and a spring 32 is provided between the lifting body 30 and the fixing member 31. In the locked state, the spring 32 continuously provides downward pressure, so that the insert 300 and the slot 100 are in a relatively stable locked state, further increasing the connection stability between the railings. When unlocking is required, simply lift the lifting body 30 to overcome the spring force, and the insert 300 and the slot 100 can be separated to release the locked state. No tools or auxiliary parts are required throughout the process, making the operation simple and convenient and significantly improving the adjustment efficiency.

[0046] Reference Figure 6 , Figure 7The lifting body 30 is a shell with an internal space. The front and rear inner walls of the lifting body 30 are respectively provided with a first locking groove 301 and a second locking groove 302 from top to bottom. The fixing member 31 is provided with locking protrusions 312 on the front and rear sides that can cooperate with the first locking groove 301 and the second locking groove 302.

[0047] Specifically, the inner wall of the lifting body 30 is provided with a first locking groove 301 and a second locking groove 302. When locked, the locking protrusion 312 of the fixing member 31 engages with the second locking groove 302, further improving the stability of the locked state. When unlocking, the lifting body 30 is lifted, and the second locking groove 302 engages with the locking protrusion 312. At this time, the spring 32 tends to push the lifting body 30 downward, but it is insufficient to overcome the deformation force of the engagement between the locking protrusion 312 and the second locking groove 302. Therefore, after the lifting body 30 is lifted to unlock, the unlocked state is maintained when no external force is applied, and the user can freely adjust the angle or position of the adjacent railing 1, which is quite convenient. When the adjustment is completed and locking is required, simply press the lifting body 30. The fixing member 31 moves downward relative to the lifting body 30, and the locking protrusion 312 of the fixing member 31 engages with the first locking groove again along the guide slope 303, completing the locking.

[0048] Furthermore, the design of the first card slot, the second card slot, and the card protrusion can improve the user's feel during adjustment, and the feedback for unlocking and locking is more obvious, avoiding accidental operation due to improper adjustment and improving the intuitiveness of operation.

[0049] A guide slope 303 is provided between the first locking groove 301 and the second locking groove 302, and the area formed between the two guide slopes 303 gradually narrows from top to bottom. Furthermore, during the up-and-down movement of the fixing member 31 relative to the lifting body 30, the inclined design of the guide slope 303 results in a larger external force required for the locking protrusion 312 to disengage from the second locking groove 302. That is, the process of unlocking by pulling up and pressing the lifting body 30 requires overcoming the spring force and the deformation elastic force of the fixing member 31 and the second locking groove 302. When locking is required after adjustment, the guide slope 303 facilitates easier entry of the locking protrusion 312 into the second locking groove 302, making the locking operation more effortless and convenient than the unlocking operation. This further increases the stability of the locking mechanism and improves the reliability of the railing 1 connection.

[0050] The fixing stud 310 and the connecting seat 21 are connected and fixed by screws 5. The lifting body 30 is also provided with a cover 33, and a connecting stud 330 is also provided under the cover 33. The connecting stud 330 extends to the lower end of the lifting body 30 and is also connected and fixed from bottom to top by screws 5. Furthermore, the connecting assembly 2 has a compact structure. The housing of the lifting body 30 integrates parts such as the insert 300 and the elastic element 32, reducing exposed parts and lowering the failure rate.

[0051] Reference Figure 8 The railing 1 includes two horizontal bars 12 and several vertical bars 11 between the horizontal bars 12. The lower horizontal bar 12 is also provided with a footrest 13. The railing 1 at the end of the fence is connected to a support member 14.

[0052] This utility model achieves integrated operation of "lifting to unlock, adjusting angle, and pressing to lock" between railings with a simplified mechanical structure, solving three major pain points in the background technology: rigid connection that cannot be adjusted, simple hinges that require auxiliary fixation, and complex adjustment parts that are inefficient to operate. While ensuring structural strength, it greatly improves the convenience of adjusting the shape of the fence and the user experience.
