[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 4 A guardrail that is easy to install includes a pillar 1 and a guardrail 3. A clamping assembly 2 is arranged between the pillar 1 and the guardrail 3. The clamping assembly 2 includes a pushing block 201 fixedly installed on the outer wall of the guardrail 3. A J-shaped clamping block 202 is fixedly installed on the top of the pushing block 201. A sleeve 203 is arranged on one side of the pushing block 201. A limiting plate 204 is fixedly installed on the outer wall of the sleeve 203. A U-shaped rod 205 is fixedly connected to the outer wall of the sleeve 203. The limiting plate 204 is located below the U-shaped rod 205. A fixing rod 206 is inserted into the U-shaped rod 205. The pushing block 201 corresponds to the limiting plate 204, and the fixing rod 206 is clamped with the J-shaped clamping block 202.

[0026] When the guardrail 3 needs to be installed with the pillar 1, the guardrail 3 is moved close to one side of the pillar 1, and the pushing block 201 is moved to the direction of the limit plate 204. When the pushing block 201 contacts the limit plate 204, the limit plate 204 is pushed toward the pillar 1. At this time, the sleeve 203 rotates, so that the U-shaped rod 205 and the fixing rod 206 swing toward the direction of the J-shaped block 202. When the fixing rod 206 contacts the top of the J-shaped block 202, the arc-shaped end of the J-shaped block 202 is just between the U-shaped rod 205 and the fixing rod 206.

[0027] At this time, pull the pushing block 201 and the guardrail 3 in the opposite direction, and the fixing rod 206 will move to the inner arc of the J-shaped block 202. At this time, the J-shaped block 202 will hook the fixing rod 206, so that the guardrail 3 and the pillar 1 cannot be easily separated, thereby realizing the installation of the pillar 1 and the guardrail 3. The assembly of the pillar 1 and the guardrail 3 can be realized by only making the pushing block 201 contact the limiting plate 204, thereby reducing the installation time.

[0028] See also Figure 2-Figure 4 A support plate 14 is provided on one side of the pillar 1, and two T-shaped blocks 4 are fixedly installed on the outer wall of the support plate 14. A connecting rod 5 is fixedly connected between the two T-shaped blocks 4. The sleeve 203 is rotatably connected to the outer wall of the connecting rod 5, and the pushing block 201 is located above the support plate 14.

[0029] The support plate 14 fixes the positions of the two T-blocks 4, making it convenient to fix the connecting rod 5 through the T-block 4. When the sleeve 203 rotates through the connecting rod 5, it can rotate along the connecting rod 5 to prevent the sleeve 203 from being displaced. When the pushing block 201 contacts the limiting plate 204, the bottom of the pushing block 201 will slide along the top of the support plate 14. The support plate 14 provides support force for the pushing block 201 and the guardrail 3, so that the pushing block 201 and the guardrail 3 will not fall off the pillar 1.

[0030] See also Figure 1 and Figure 3 A fixing plate 7 is fixedly installed on the outer wall of the pillar 1, and a plurality of screws 8 are threadedly connected between the fixing plate 7 and the pillar 1. The support plate 14 and the T-shaped block 4 are both fixedly installed on the outer wall of the fixing plate 7, and a tension spring 6 is connected between the limit plate 204 and the fixing plate 7.

[0031] The fixing plate 7 is installed on the outer wall of the pillar 1, and the connection between the fixing plate 7 and the pillar 1 is made tighter by multiple screws 8, so that the fixing plate 7 has a better load-bearing capacity, and then the T-shaped block 4 and the support plate 14 are fixedly connected to the fixing plate 7, so that the support plate 14 and the T-shaped block 4 can provide a more stable supporting force for the clamping assembly 2, and when the pushing block 201 contacts the limiting plate 204, the limiting plate 204 will squeeze the tension spring 6, and when the guardrail 3 is removed, the pushing block 201 will release the contact with the limiting plate 204, and at this time the tension spring 6 will bounce the limiting plate 204 back to its original position.

[0032] Embodiment 2:

[0033] See also Figure 3-Figure 4 One end of the fixed rod 206 extending to the outside of the U-shaped rod 205 is fixedly connected to a mounting block 9, two return springs 10 are connected between the mounting block 9 and the U-shaped rod 205, and two guide rods 12 are fixedly installed on the outer wall of the U-shaped rod 205, and the mounting block 9 is slidably connected to the guide rod 12.

[0034] When it is necessary to separate the guardrail 3 from the pillar 1, pulling the mounting block 9 can drive the fixing rod 206 to move to one side. The mounting block 9 will slide along the guide rod 12 during movement, so that the fixing rod 206 and the mounting block 9 can maintain horizontal movement during movement. When the fixing rod 206 is pulled to a position close to the return spring 10, the connection with the J-shaped block 202 can be released. At this time, the guardrail 3 can be removed from the two pillars 1, and then the mounting block 9 can be loosened to use the elastic force of the return spring 10 to bounce the fixing rod 206 back to its original position.

[0035] See also Figure 4 The fixing rod 206 is located between the two return springs 10 , the guide rod 12 is located inside the return spring 10 , and a circular baffle 13 is fixedly installed on one end of the two guide rods 12 away from the U-shaped rod 205 .

[0036] The circular baffle 13 limits one end of the guide rod 12 to prevent the mounting block 9 from sliding off the outer wall of the guide rod 12 when the mounting block 9 slides along the guide rod 12, so that the mounting block 9 can no longer move toward the outside of the guide rod 12 after moving to the circular baffle 13.

[0037] See also Figure 4 The mounting block 9 is provided with two insertion holes 11 , and the insertion holes 11 are located between the two guide rods 12 .

[0038] When pulling the installation block 9 , the user can insert two fingers into the insertion hole 11 and then hook the installation block 9 to move. The insertion hole 11 makes the installation block 9 easier to manipulate, making it convenient for the user to move the installation block 9 .

[0039] Working principle:

[0040] When the guardrail 3 needs to be installed with the pillar 1, the guardrail 3 is moved close to one side of the pillar 1, and the pushing block 201 is moved to the direction of the limit plate 204. When the pushing block 201 contacts the limit plate 204, the limit plate 204 is pushed toward the pillar 1. At this time, the sleeve 203 rotates, so that the U-shaped rod 205 and the fixing rod 206 swing toward the direction of the J-shaped block 202. When the fixing rod 206 contacts the top of the J-shaped block 202, the arc-shaped end of the J-shaped block 202 is just between the U-shaped rod 205 and the fixing rod 206.

[0041] At this time, pull the pushing block 201 and the guardrail 3 in the opposite direction, and the fixing rod 206 will move to the inner arc of the J-shaped block 202. At this time, the J-shaped block 202 will hook the fixing rod 206, so that the guardrail 3 and the pillar 1 cannot be easily separated, thereby realizing the installation of the pillar 1 and the guardrail 3. The assembly of the pillar 1 and the guardrail 3 can be realized by only making the pushing block 201 contact the limiting plate 204, thereby reducing the installation time.

[0042] When it is necessary to separate the guardrail 3 from the pillar 1, pulling the mounting block 9 can drive the fixing rod 206 to move to one side. The mounting block 9 will slide along the guide rod 12 during movement, so that the fixing rod 206 and the mounting block 9 can maintain horizontal movement during movement. When the fixing rod 206 is pulled to a position close to the return spring 10, the connection with the J-shaped block 202 can be released. At this time, the guardrail 3 can be removed from the two pillars 1, and then the mounting block 9 can be loosened to use the elastic force of the return spring 10 to bounce the fixing rod 206 back to its original position.
