Description

A new type of flexible anti-collision post for industrial doors Technical Field

[0001] This utility model relates to the field of industrial door technology, specifically to a novel flexible anti-collision post for industrial doors. Background Technology

[0002] The main problems with commonly used crash barriers in the industrial and transportation sectors are as follows:

[0003] 1. High overall replacement cost: Most flexible bollards (such as rubber bollards or hydraulic buffer bollards) adopt an integrated design. If there is partial damage (such as the outer tube breaking), the whole set needs to be replaced, resulting in high maintenance costs.

[0004] 2. Simple buffer structure: It relies on a single layer of rubber wrapping or spring structure, which has low energy absorption efficiency (it can only disperse 30%-40% of the impact force) and is prone to failure due to material fatigue after long-term use.

[0005] 3. Installation complexity: Traditional anchoring methods (such as expansion bolts) are prone to loosening under dynamic loads and require frequent reinforcement. Some chemical anchors may shift due to solidification shrinkage, affecting verticality.

[0006] Some improved crash barriers attempt to reduce costs through detachable structures, but shortcomings remain:

[0007] Poor compatibility: The buffer component is bound to the outer tube size and cannot be adapted to flexible outer tubes of different diameters (such as Φ80mm and Φ100mm, which require special buffer sleeves).

[0008] Insufficient cushioning performance: Ordinary rubber sleeves and steel cylinders are rigidly connected, and when impacted, they cannot dissipate energy through multi-stage deformation, but can only absorb the impact through material compression.

[0009] In summary, this utility model designs a novel flexible anti-collision post for industrial doors. Summary of the Invention

[0010] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of flexible anti-collision post for industrial doors, which has a simple structure, is easy and quick to install and replace, has a good buffering effect, low replacement cost, and strong practicality.

[0011] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel flexible anti-collision post for industrial doors, comprising a cap, a flexible outer tube, a buffer sleeve, a metal gasket, a rubber gasket, a metal base, and a chemical bolt. The bottom of the chemical bolt is anchored by anchoring adhesive, and the upper end of the chemical bolt passes through the metal base and is fixed by the rubber gasket, the metal gasket, and the nut. Multiple buffer sleeves are fitted onto the steel cylinder on the metal base, and a flexible outer tube is fitted onto the outside of the buffer sleeve. A cap is fitted onto the top of the flexible outer tube.

[0012] Preferably, the buffer sleeve is fixed to the steel cylinder by fixing screws.

[0013] Preferably, the flexible outer tube is made of HDPE.

[0014] Preferably, the metal base and the steel cylinder are an integral structure.

[0015] The beneficial effects of this utility model are as follows: This utility model, through the combination design of metal base steel cylinder and replaceable buffer sleeve, can efficiently absorb impact force and has a simple structure; its modular design allows only the buffer sleeve to be replaced to adapt to different specifications of outer tubes, which significantly reduces maintenance and replacement costs. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0017] Figure 1 is a schematic diagram of the structure of this utility model;

[0018] Figure 2 is an exploded view of this utility model. Detailed Implementation

[0019] 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.

[0020] Referring to Figures 1-2, the specific embodiment adopts the following technical solution: a novel flexible anti-collision post for industrial doors, including a cap 1, a flexible outer tube 2, a buffer sleeve 4, a metal gasket 5, a rubber gasket 6, a metal base 7, and a chemical bolt 8. The bottom of the chemical bolt 8 is anchored by a rebar adhesive, and the upper end of the chemical bolt 8 passes through the metal base 7 and is fixed by the rubber gasket 6, the metal gasket 5, and a nut. Multiple buffer sleeves 4 are sleeved on the steel cylinder on the metal base 7. The flexible outer tube 2 is sleeved on the outside of the buffer sleeve 4, and the cap 1 is sleeved on the top of the flexible outer tube 2.

[0021] It is worth noting that the buffer sleeve 4 is fixed to the steel cylinder by the fixing screw 3.

[0022] It is worth noting that the flexible outer tube 2 is made of HDPE.

[0023] Furthermore, the metal base 7 and the steel cylinder are an integral structure.

[0024] The installation method of this specific embodiment is as follows: Drill holes with a diameter of 18-22 mm and a depth of 100-125 mm. Clean the dust inside the holes. Fill each installation hole with three-quarters of the volume of anchoring adhesive. Rotate the bolts to insert them so that the anchoring adhesive and bolts can adhere better. Clean up any overflowing anchoring adhesive in time to avoid subsequent solidification that cannot be handled. The anchoring adhesive has a solidification time of 12 hours. Insert the base into the bolts before the anchoring adhesive has solidified. The anchoring adhesive will shrink during solidification. Use the base to prevent excessive displacement. After the anchoring adhesive has solidified, put down the rubber gasket and metal gasket in sequence. Then put down the bolt, gasket, and nut and tighten them. Then put on the buffer sleeve. Finally, put on the flexible outer tube and cap in sequence.

[0025] This specific embodiment features one or more buffer sleeves mounted on a steel cylinder on a metal base. Because the steel cylinder on the metal base and the buffer sleeves on the cylinders can absorb more impact force than other types of flexible crash barriers, its simple structure makes installation and replacement easier. Other flexible crash barriers require complete replacement when a new specification is needed, while this flexible crash barrier allows for replacement of the buffer sleeves according to different specifications of the flexible outer tube, resulting in low replacement costs.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
