Description

Technical Field

[0001] This utility model relates to the technical field of door seals for loading and unloading platforms, specifically a door seal for loading and unloading platforms with a buffering and stabilizing function. Background Technology

[0002] Sponge-type door seals are mainly installed in places with high insulation requirements and strong sealing properties. During loading and unloading, the warehouse door is opened, and the vehicle reverses so that the outlet of the cargo box is aligned with the warehouse door. At this time, the edge of the cargo box outlet abuts against the sponge-type door seal, thus achieving a sealing effect.

[0003] According to a public notice (Announcement No.: CN210127801U) of a sponge-type door seal for loading and unloading goods in a warehouse, the above application uses a first longitudinal reflective strip and a transverse reflective strip to warn truck drivers of the length and width of the top seal and top pressure strip. The second longitudinal reflective strip and reflective sheet also warn truck drivers of the position and height of the side seal, which facilitates truck drivers in adjusting the position of the entrance when loading and unloading box cargo. It also reduces the collision between the box cargo and the door seal during the adjustment process, greatly reduces the air flow rate in the connection gap, and thus improves the heat preservation and airtightness of the unloading of the cargo box. By setting a canvas abrasion-resistant sheet and a canvas roll, it can provide a certain degree of cushioning and improve the abrasion resistance of the side seal, that is, increase the service life of the door seal.

[0004] However, in actual use, although the above-mentioned equipment can perform buffer sealing, it cannot adapt well to unevenness on the upper side of the cargo box, resulting in gaps remaining at the sealing point. In view of this, we propose a door seal for loading and unloading platforms with buffer stabilization function. Utility Model Content

[0005] The purpose of this invention is to provide a door seal for a loading and unloading platform with a buffering and stabilizing function, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a door seal for a loading and unloading platform with buffering and stabilizing function, comprising a frame, wherein a buffer assembly is provided on the inner wall of the frame, the buffer assembly includes a receiving groove, the receiving groove is opened on the inner wall of the frame, an extension protective sleeve is fixedly connected to the inner wall of the receiving groove, a long rod groove is opened on the outer wall of the extension protective sleeve, a transmission groove is opened on the outer wall of the extension protective sleeve, a guide groove is opened on the outer wall of the extension protective sleeve, a pressing rod is fixedly connected to the inner wall of the receiving groove, a motor is fixedly connected to the outer wall of the frame, and a threaded rod is fixedly connected to the output end of the motor through the frame and the extension protective sleeve;

[0007] A threaded slider is threadedly connected to the outer wall of a threaded rod. An L-shaped flexible rod is fixedly connected to the outer wall of the threaded slider. A sliding block is slidably connected to the inner wall of the L-shaped flexible rod. A spring is fixedly connected to the outer wall of the sliding block. A clamping rubber plate is fixedly connected to the outer wall of the sliding block. A fixing plate is fixedly connected to the outer wall of the sliding block. A pressure-bearing inclined plate is fixedly connected to the outer wall of the fixing plate. A sponge cross plate is provided on the inner wall of the extension protective sleeve. A guide plate is fixedly connected to the inner wall of the receiving groove.

[0008] Preferably, the number of sliding blocks is several, and the several sliding blocks are arranged in a linear array on the inner wall of the L-shaped tough rod.

[0009] Preferably, the number of clamping rubber plates is several, and the several clamping rubber plates are arranged on both sides mirroring the center plane of the spring, so that the clamping rubber plates can be smoothly displaced towards the center after being subjected to force.

[0010] Preferably, the outer wall of the pressure plate is adapted to the outer wall of the extrusion rod, so that the pressure plate is squeezed by the extrusion rod when it is displaced.

[0011] Preferably, the outer wall of the sponge horizontal plate is provided with a rubbing component, the rubbing component includes an arc-shaped pressure block, the arc-shaped pressure block is fixedly connected to the outer wall of the sponge horizontal plate, an upper friction strip is fixedly connected to the outer wall of the sponge horizontal plate, and a lower friction strip is fixedly connected to the inner wall of the extension protective sleeve.

[0012] Preferably, the outer wall of the lower friction strip is adapted to the outer wall of the upper friction strip.

[0013] Compared with the prior art, this utility model provides a door seal for a loading and unloading platform with a buffering and stabilizing function, which has the following beneficial effects:

[0014] 1. The loading and unloading platform door seal with buffering and stabilizing function ensures that the edge of the cargo box exit abuts against the door seal. Then, the motors on both sides are started, followed by the motor at the top. This allows the threaded slider limited by the guide plate to move linearly, which in turn allows the L-shaped flexible rod to move smoothly. This allows the clamping rubber plate and the sponge cross plate to move smoothly, and the extension protective sleeve to cover the perimeter of the cargo box smoothly and with buffering. When the L-shaped flexible rod moves, the extrusion rod will continuously squeeze the pressure inclined plate, which will cause the fixed plate and the sliding block to move inward. Finally, the clamping rubber plate can further fit the sponge cross plate and the extension protective sleeve into the cargo box by clamping them, ensuring the sealing performance of the door seal.

[0015] 2. The door seal of the loading and unloading platform with buffering and stabilizing function, when the sponge cross panel and the stretch protective sleeve can fit more closely to the cargo box, the arc-shaped pressure block will provide additional clamping force to the clamping rubber plate, so that the sponge cross panel can shrink better, and the set lower friction strip and upper friction strip can make the sponge cross panel and the stretch protective sleeve fit more tightly, ultimately allowing the stretch protective sleeve to fit the cargo box better, thereby further improving the overall practicality.

Detailed Implementation

[0025] like Figures 1-8As shown, this utility model provides a technical solution: a door seal for a loading and unloading platform with buffering and stabilizing function, including a frame 1, a buffer assembly 2 provided on the inner wall of the frame 1, the buffer assembly 2 including a receiving groove 201, the receiving groove 201 being opened on the inner wall of the frame 1, an extension protective sleeve 202 fixedly connected to the inner wall of the receiving groove 201, a long rod groove 203, a transmission groove 204, and a guide groove 205 on the outer wall of the extension protective sleeve 202, a pressing rod 206 fixedly connected to the inner wall of the receiving groove 201, a motor 207 fixedly connected to the outer wall of the frame 1, and a threaded rod 208 fixedly connected to the output end of the motor 207 through the frame 1 and the extension protective sleeve 202.

[0026] Furthermore, the threaded slider 209 is threadedly connected to the outer wall of the threaded rod 208. An L-shaped flexible rod 210 is fixedly connected to the outer wall of the threaded slider 209. A sliding block 211 is slidably connected to the inner wall of the L-shaped flexible rod 210. A spring 212 is fixedly connected to the outer wall of the sliding block 211. A clamping rubber plate 213 is fixedly connected to the outer wall of the sliding block 211. A fixing plate 214 is fixedly connected to the outer wall of the sliding block 211. A pressure-bearing inclined plate 215 is fixedly connected to the outer wall of the fixing plate 214. A sponge horizontal plate 216 is provided on the inner wall of the extension protective sleeve 202. A guide plate 217 is fixedly connected to the inner wall of the receiving groove 201.

[0027] In an embodiment of this utility model, the number of sliding blocks 211 is several, and the several sliding blocks 211 are arranged in a linear array on the inner wall of the L-shaped tough rod 210. The number of clamping rubber plates 213 is several, and the several clamping rubber plates 213 are mirror images of the center plane of the spring 212 on both sides, so that the clamping rubber plates 213 can be smoothly displaced towards the center after being subjected to force. The outer wall of the pressure inclined plate 215 is adapted to the outer wall of the extrusion rod 206, so that the pressure inclined plate 215 will be squeezed by the extrusion rod 206 when it is displaced.

[0028] Furthermore, the outer wall of the sponge horizontal plate 216 is provided with a rubbing component 3, the rubbing component 3 includes an arc-shaped pressure block 301, the arc-shaped pressure block 301 is fixedly connected to the outer wall of the sponge horizontal plate 216, the outer wall of the sponge horizontal plate 216 is fixedly connected with an upper friction strip 303, the inner wall of the extension protective sleeve 202 is fixedly connected with a lower friction strip 302, and the outer wall of the lower friction strip 302 is adapted to the outer wall of the upper friction strip 303.

[0029] In this utility model, during daily use, the vehicle reverses so that the cargo box outlet is aligned with the warehouse door, and the edge of the cargo box outlet abuts against the door seal. Then, the motors 207 on both sides are started, followed by the motor 207 on top. This causes the threaded slider 209, which is limited by the guide plate 217, to move linearly. This allows the L-shaped flexible rod 210 to move smoothly, enabling the clamping rubber plate 213 and the sponge cross plate 216 to move smoothly. This allows the extension protective sleeve 202 to cover the periphery of the cargo box smoothly and with cushioning. As the L-shaped flexible rod 210 moves, the extrusion rod 206 continuously presses the pressure inclined plate 215, causing the fixing plate 214 and the sliding block 211 to move inward. Finally, the clamping rubber plate 213 clamps the sponge cross plate 216 and the extension protective sleeve 202, allowing the sponge cross plate 216 and the extension protective sleeve 202 to further fit the cargo box.

[0030] When the sponge cross panel 216 and the stretch protective sleeve 202 are further fitted to the cargo box, the arc-shaped pressure block 301 will provide additional clamping force to the clamping rubber plate 213, so that the sponge cross panel 216 can shrink better. Furthermore, the lower friction strip 302 and the upper friction strip 303 can make the sponge cross panel 216 and the stretch protective sleeve 202 fit more tightly, ultimately allowing the stretch protective sleeve 202 to fit the cargo box better, thereby further improving the overall practicality.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
