Description

Technical Field

[0001] This utility model relates to the field of fork technology, specifically to a telescopic fork body with buffer protection function. Background Technology

[0002] With social development and increasing commodity circulation, automated warehousing, as a transit point for goods storage, greatly improves the inbound and outbound capacity and space storage efficiency. For small-batch, multi-category, and high-output goods, forklifts can achieve multi-level, layered picking and flexible configuration in a single aisle, improving warehouse inbound and outbound efficiency. They play an increasingly important role in automated logistics systems. Forks are the most commonly used picking device on forklifts, hence the name "forklift." Forks are typically L-shaped, with the horizontal section for placing and lifting goods and the vertical section for support. To improve cargo transportation efficiency, a fork body is needed; however, existing fork bodies still have the following shortcomings:

[0003] For example, the utility model with publication number CN206842986U discloses a fork. The fork provided by this utility model has a protrusion at the corner of the L-shaped main support, which increases the thickness of the L-shaped main support at the corner, thereby improving the load-bearing capacity of the L-shaped main support and the strength of the fork, preventing the fork from breaking at its corner, and improving the safety performance of the fork. However, similar to the prior art of the above application, when the existing fork body is used, since most fork bodies do not have a buffer structure, the fork and the goods are easily damaged when the fork comes into contact with the goods or shelves, resulting in economic losses and causing problems such as reduced practicality and reduced efficiency of the fork body. Utility Model Content

[0004] The purpose of this invention is to provide a telescopic fork body with a buffer protection function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a telescopic fork body with buffer protection function, comprising a fork body, a telescopic arm body, and a buffer assembly. The telescopic arm body is provided on the outside of the fork body, and a buffer assembly is provided at the front end of the telescopic arm body. The buffer assembly includes a limiting groove, a spring damping rod, a movable frame, a protective front plate, a limiting slider, a limiting through hole, a limiting rod, and a rubber protective pad. Spring damping rods are installed on both sides inside the limiting groove, and a movable frame is installed at the front end of the spring damping rod. A protective front plate is added to the front end of the movable frame. Limiting sliders are added on both sides outside the movable frame. Limiting through holes are opened inside the limiting sliders, and limiting rods are connected inside the limiting through holes. A rubber protective pad is added to the upper end of the telescopic arm body, and the telescopic assembly is provided inside the fork body.

[0006] Furthermore, the internal dimensions of the limiting groove are adapted to the external dimensions of the movable frame, and the movable frame is elastically connected to the limiting groove via a spring damping rod.

[0007] Furthermore, there are two limiting sliders, and the two limiting sliders are symmetrically arranged on both sides of the outside of the active frame with respect to the central axis of the front of the active frame.

[0008] Furthermore, the internal dimensions of the limiting through hole are adapted to the external dimensions of the limiting rod, and the limiting rod is embeddedly connected to the limiting slider through the limiting through hole.

[0009] Furthermore, the telescopic component includes a mounting slot, a limiting frame, and a servo motor. The limiting frame is installed inside the mounting slot, and a servo motor is added to the outer end of the limiting frame.

[0010] Furthermore, the telescopic assembly also includes a lead screw, a movable slider, and mounting blocks. The lead screw is connected to the front end of the servo motor, and the movable slider is connected to the outside of the lead screw. Mounting blocks are added to both sides of the movable slider.

[0011] Furthermore, the limiting frame is embedded in the mounting groove, and the limiting frame is fixedly connected to the fork body through the mounting groove.

[0012] Furthermore, the external dimensions of the movable slider are adapted to the internal dimensions of the limiting frame, and the movable slider is slidably connected to the limiting frame via a lead screw.

[0013] This utility model provides a telescopic fork body with a buffer protection function, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of the buffer component, enables the movable frame to be elastically connected to the limiting groove through the spring damping rod when the telescopic fork with buffer protection function is in use. The limiting slider is fixedly installed on both sides of the outside of the movable frame. The limiting through hole and the limiting rod are used to increase the stability of the limiting slider during the movement of the limiting slider, thereby avoiding positional deviation when the movable frame moves elastically. The protective front plate set on the outside of the movable frame protects the front end of the fork during use. In addition, the rubber protective pad added to the upper end of the telescopic arm body increases the cushioning when in contact with the goods, improving the overall practicality and efficiency of the fork.

[0015] 2. By setting up a telescopic component, this utility model enables the telescopic fork body with buffer protection function to be used. When the servo motor at the left end of the limit frame drives the lead screw to rotate, the movable slider connected to the lead screw moves accordingly, and the mounting block is fixedly installed on both sides of the movable slider. The telescopic arm body is installed on the outside of the fork body through the mounting block. The movement of the movable slider causes the mounting block to move and adjusts the usage position of the telescopic arm body, increasing the flexibility and dynamism of the fork body during use.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3As shown, a telescopic fork body with a buffer protection function includes a fork body 1, a telescopic arm body 2, and a buffer assembly 3. The telescopic arm body 2 is disposed outside the fork body 1, and the buffer assembly 3 is disposed at the front end of the telescopic arm body 2.

Limiting through holes 306 are formed inside the limiting sliders 305, and limiting rods 307 are connected inside the limiting through holes 306. A rubber protective pad 308 is added to the upper end of the telescopic arm body 2. The internal dimensions of the limiting groove 301 are adapted to the external dimensions of the movable frame 303, and the movable frame 303 is elastically connected to the limiting groove 301 via a spring damping rod 302. Two limiting sliders 305 are provided, and the two limiting sliders 305 are positioned relative to the front of the movable frame 303. The center axis is symmetrically arranged on both sides of the outer side of the movable frame 303. The internal dimensions of the limiting through hole 306 are adapted to the external dimensions of the limiting rod 307, and the limiting rod 307 is embeddedly connected to the limiting slider 305 through the limiting through hole 306. The spring damping rod 302 is fixedly installed in the limiting groove 301 opened at the front end of the telescopic arm body 2 by fastening bolts, and the movable frame 303 is fixedly installed at the front end of the spring damping rod 302 with the fastening bolts, so that the movable frame 303 is elastically connected to the limiting groove 301 through the spring damping rod 302, and the limiting slider 305 is fixedly installed on the movable frame. On both sides of the outside of 303, the internal dimensions of the limiting through holes 306 inside the limiting slider 305 are adapted to the external dimensions of the limiting rod 307. Thus, the limiting through holes 306 and the limiting rod 307 increase the stability of the limiting slider 305 during movement, thereby preventing positional deviation when the movable frame 303 moves elastically. The protective front plate 304 set on the outside of the movable frame 303 protects the front end of the fork during use. In addition, the rubber protective pad 308 added to the upper end of the telescopic arm body 2 increases the cushioning when in contact with the goods, improving the overall practicality and efficiency of the fork.

[0022] like Figure 1 and Figure 3As shown, a telescopic assembly 4 is provided inside the fork body 1. The telescopic assembly 4 includes a mounting groove 401, a limiting frame 402, and a servo motor 403. The limiting frame 402 is installed inside the mounting groove 401, and the servo motor 403 is added to the outer end of the limiting frame 402. The telescopic assembly 4 also includes a lead screw 404, a movable slider 405, and mounting blocks 406. The front end of the servo motor 403 is connected to the lead screw 404, and the movable slider 405 is connected to the outside of the lead screw 404. Mounting blocks 406 are added to both sides of the movable slider 405.

The external dimensions of the movable slider 405 are adapted to the internal dimensions of the limiting frame 402, and the movable slider 405 is connected to the fork body 1 through the lead screw. 404 is slidably connected to the limiting frame 402. The limiting frame 402 is fixedly installed in the mounting groove 401 opened inside the fork body 1 by fastening bolts. The servo motor 403 is fixedly installed on the left end of the limiting frame 402 with the fastening bolts. The output shaft of the servo motor 403 is connected to the lead screw 404 through a coupling. The operation of the servo motor 403 drives the lead screw 404 to rotate, so that the movable slider 405 connected to the outside of the lead screw 404 moves accordingly. The mounting block 406 is fixedly installed on both sides of the movable slider 405. The telescopic arm body 2 is installed on the outside of the fork body 1 through the mounting block 406. The movement of the movable slider 405 drives the mounting block 406 to move and adjusts the use position of the telescopic arm body 2 accordingly, increasing the flexibility and mobility of the fork body during use.

[0023] In summary, when using this telescopic fork with buffer protection function, the limiting frame 402 is first fixedly installed in the mounting groove 401 inside the fork body 1 using fastening bolts.

At the same time, the telescopic arm body 2 is sleeved and installed on the outside of the fork body 1, and the front end of the mounting block 406 is fixedly installed to the telescopic arm body 2 using fastening bolts. This causes the movable slider 405 to move, causing the mounting block 406 to move and follow the movement of the sliding block 405. The position of the telescopic arm body 2 is adjusted. Then, the movable frame 303 is elastically connected to the limiting groove 301 by the spring damping rod 302. The limiting slider 305 is fixedly installed on both sides of the movable frame 303. The limiting through hole 306 and the limiting rod 307 are used to increase the stability of the limiting slider 305 during movement, thereby avoiding positional deviation when the movable frame 303 moves elastically. The protective front plate 304 set on the outside of the movable frame 303 protects the front end of the fork during use. The rubber protective pad 308 added to the upper end of the telescopic arm body 2 increases the cushioning when in contact with the goods, improving the overall practicality and efficiency of the fork.
