SUMMARY

[0005] The purpose of the present application is to provide a municipal building fence that can solve the above problems.

[0006] The purpose of the present application is to provide a municipal building fence, which comprises:

[0007] The supporting column comprises a base and a vertical rod arranged on the base.

[0008] The protective net comprises an outer frame and a plurality of vertical rods arranged in the outer frame.

[0009] The connecting mechanism is arranged on the vertical rod and the outer frame, and is used for connecting the vertical rod and the outer frame together.

[0010] The connecting mechanism is arranged on the vertical rod and the outer frame, and is used for connecting the vertical rod and the outer frame together.

[0011] The municipal building fence has the advantages that the installation and disassembly process of the municipal building fence is more convenient, no additional tools such as wrenches or screwdrivers are needed, time is saved, and the operation is convenient, the connection mechanism is used to achieve the plug-in connection, the components of the fence can be easily separated, and the plug-in connection achieved by the connection mechanism has a certain degree of firmness and cannot be easily disassembled.

[0012] The simplified installation and disassembly process and the reduced need for additional tools help to reduce the installation and maintenance cost of the fence, and the durability and reusability of the plug-in design further improve the cost-effectiveness.

[0013] Further, the connection mechanism comprises:

[0014] The first mounting ear is provided on the outer frame, and a first through hole is formed on the surface thereof;

[0015] The second mounting ear is provided on the support column, and a second through hole is formed on the surface thereof, and the second mounting ear is provided with two insertion slots for the first mounting ear to be inserted into;

[0016] The quick plug-in assembly comprises a plug-in piece and a receiving piece;

[0017] The plug-in piece and the receiving piece are connected together by plug-in, and the separation of the plug-in piece and the receiving piece can be completed by pressing.

[0018] The installation of the first mounting ear and the second mounting ear can provide basic support for the installation of the connection structure, and at the same time, the installer can intuitively see and operate the plug-in process, the first mounting ear is inserted into the insertion slot of the second mounting ear to form a preliminary guide and alignment, and the connection mechanism is sequentially inserted through the second through hole and the first through hole, and the plug-in is completed after the second through hole. At the same time, in the quick plug-in assembly of the present application, the combination of the plug-in piece and the receiving piece can complete the connection by simple plug-in, and their separation can be realized by pressing, thereby eliminating the dependence on additional tools, making the installation and disassembly process extremely fast and simple.

[0019] Although the connection process of the present application is simplified, the locking mechanism in the quick plug-in assembly, i.e. the plug-in piece and the receiving piece cannot be separated by pulling outward after plug-in is completed, only by pressing inward can the separation be completed, which can ensure the stability and safety of the connection under normal use conditions.

[0020] Further, the receiving piece comprises:

[0021] The first pressing plate is provided with a mounting protrusion on the top thereof, and a mounting slot is formed on the mounting protrusion;

[0022] The limiting protrusions are arranged on the inner wall of the mounting groove and are provided with two;

[0023] The mounting channel includes a first channel and a second channel arranged between the two limiting protrusions, and a third channel arranged between the limiting protrusions and the mounting groove;

[0024] The positioning groove is arranged on the limiting protrusion and is located at the connection of the first channel and the second channel;

[0025] The limiting protrusions are arranged in pairs on both sides of the mounting groove, and the diameter of the limiting protrusion is the same as the inner diameter of the first through hole and the second through hole.

[0026] The first pressing plate is circular to provide stable support. The design of the mounting protrusion makes it easier for the receiving member to align with the plug-in member and provides additional strength to support the plug-in member. The limiting protrusion is arranged on the inner wall of the mounting groove to guide and fix the plug-in member. The two limiting protrusions form a pair to ensure that the plug-in member does not deviate from the predetermined path during insertion. The diameter of the limiting protrusion is the same as the inner diameter of the first through hole and the second through hole, ensuring that the plug-in member can smoothly pass through these holes and dock with the receiving member. The mounting channel includes a first channel and a second channel, which are located between the two limiting protrusions and formed by the two limiting protrusions, providing a path for the plug-in member to insert. The third channel is located between the limiting protrusion and the mounting groove to guide the separation of the receiving member and the plug-in member. The positioning groove is arranged on the limiting protrusion and is located at the connection of the first channel and the second channel. When the plug-in member is correctly inserted into the positioning groove, a firm connection can be achieved to prevent accidental dislodgement of the plug-in member.

[0027] The design of the limiting protrusion and the mounting channel ensures that the plug-in member can be accurately inserted into the receiving member, avoiding deviation during installation. The introduction of the positioning groove further enhances the stability of the connection and prevents accidental dislodgement of the plug-in member. The first channel and the second channel guide the insertion of the plug-in member, facilitating subsequent fixation. The third channel is used to guide the separation of the plug-in member, facilitating disassembly. The cooperation of the receiving member and the plug-in member makes the plug-in process more intuitive and simple, without the need for additional tools or complex operations, improving installation efficiency.

[0028] Further, the plug-in member includes:

[0029] The second pressing plate;

[0030] The limiting member is arranged on the second pressing plate and consists of two limiting rods. Each limiting rod includes a rod portion and a bent portion.

[0031] Wherein, the limiting rod is inserted into the receiving part, and then fixed with the positioning slot under the guidance of the first channel, completing the locking, and separated from the receiving part under the guidance of the second channel and the third channel, completing the disassembly.

[0032] The second pressing plate is also circular, used to provide stable support, and corresponds to the first pressing plate of the receiving part. The limiting part is composed of two limiting rods, which play a role in cooperating with the limiting protrusion and the positioning slot in the receiving part. Each limiting rod includes a rod part and a bent part, wherein the rod part provides support, and the bent part is used to lock or unlock with the positioning slot.

[0033] During the insertion process, the bent part of the limiting rod first enters the first channel of the receiving part, and as the plug-in part goes deeper, the limiting rod is gradually guided by the first channel to approach the positioning slot. When the bent part of the limiting rod reaches the positioning slot, it will be locked by the positioning slot, thereby firmly fixing the plug-in part in the receiving part. When disassembling, the bent part of the limiting rod can be unlocked from the positioning slot by pressing, and then exit the receiving part along the second channel and the third channel. In addition, in this application, the limiting rod is made of elastic metal material, which can deform to a certain extent, so as to adapt to the diameter change of each channel, and can cooperate with the positioning slot through the reset after deformation.

[0034] Further, the first pressing plate is provided with an annular protrusion, and the second pressing plate is provided with a plug rod matched with the annular protrusion.

[0035] The annular protrusion is installed on the first pressing plate as part of the receiving part, used to provide a support surface. The plug rod is provided on the second pressing plate as part of the plug-in part, matched with the annular protrusion to ensure the butt joint between the plug-in part and the receiving part. The spring is located between the plug rod and the annular protrusion, playing a role in buffering and supporting. The spring force can resist accidental pressing or external impact force, preventing the plug-in part and the receiving part from accidental separation. Through the cooperation of the annular protrusion, the plug rod and the spring, the connection between the plug-in part and the receiving part is more firm and stable. At the same time, the user only needs to exert enough force to overcome the spring force to complete the disassembly, without the need for additional tools or complex operations.

[0036] Further, the diameter of the first channel gradually decreases from outside to inside, the diameter of the second channel to the third channel gradually increases, the third channel is communicated with the mounting slot, and the limiting protrusion is provided with a guide angle at one end of the second channel and the third channel.

[0037] The diameter of the first channel gradually decreases from outside to inside, which can play a guiding and positioning role. During the insertion process of the plug-in part, the gradually decreasing diameter can guide the limiting rod to gradually align with the positioning groove, ensuring that the plug-in part can be smoothly and accurately inserted into the receiving part. The diameters of the second channel to the third channel gradually increase, which can provide sufficient space for the plug-in part during disassembly, so that it can easily exit from the receiving part. Moreover, in the present application, the third through groove is in communication with the mounting groove, that is, as long as the plug-in part enters the third channel, it can be directly pulled out.

[0038] At the same time, the limiting protrusion located at one end of the intersection of the second channel and the third through groove is provided with a guide angle, which further enhances the guiding property of the plug-in part. The guide angle can guide the plug-in part to exit along the correct path during disassembly, avoiding jamming and further improving the disassembly efficiency.

[0039] The beneficial effects of the present application are:

[0040] 1. By adopting plug-in connection as the connecting mechanism, the installation and disassembly process of the municipal building fence of the present application becomes more convenient, without relying on additional tools such as wrenches or screwdrivers, which not only saves time but also improves the convenience of operation.

[0041] 2. Through the simplified installation and disassembly process and the reduction of the demand for additional tools, it helps to reduce the installation and maintenance cost of the fence, and the durability and reusability of the plug-in design also further improve the cost-effectiveness.

[0042] 3. Although the connection process of the present application is simplified, the locking mechanism in the quick plug-in assembly, that is, after the plug-in is completed, it cannot be separated from the receiving part by pulling it outward, only by pressing it inward can the separation be completed, which can ensure the stability and safety of the connection under normal use conditions.
