Description

Technical Field

[0001] This utility model relates to the field of elevator transportation technology, and more specifically, to a freight elevator. Background Technology

[0002] An elevator is a type of electromechanical equipment that uses power to achieve vertical or inclined transportation, and is widely used for transporting people and goods within buildings. Elevators are commonly used in shopping malls for goods handling.

[0003] Existing moving elevators typically consist of only a single floor panel without any limiting or restraining mechanisms for goods. During transport, goods are prone to tipping and colliding, which not only damages them but also requires workers to carefully lift and rearrange them, resulting in wasted time and effort. Utility Model Content In view of the problems existing in the prior art, the purpose of this utility model is to provide a freight elevator that can limit and block goods to prevent them from tipping over and colliding.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A freight elevator, comprising: An elevator car has a base for carrying goods; A sliding groove is provided on the base plate; The slider is movably disposed within the groove. Several barriers are installed on the slider to intercept goods; A locking block is disposed on the slider and located within the slide groove; the locking block has a cavity. A cam, rotatably disposed at the center of the cavity; and A clamping element is disposed around the cam within the cavity and passes through the block wall, pressing against the inner wall of the slide groove; the cam rotates to press the clamping element against the inner wall of the slide groove, thereby locking the block. In some embodiments, at least two slide grooves are provided; the slide grooves are arranged in a cross shape within the base plate.

[0006] The technical solutions described in this application have at least the following technical effects: The elevator base plate is equipped with a slide rail, in which movable locking blocks and guardrails are installed. When the guardrails need to be moved, a cam is rotated to release the guardrails. After the worker manually moves the guardrails to the designated position, the cam is rotated again to make the clamping parts press against the inner wall of the slide rail to fix the guardrails. The guardrails limit and fix the goods, preventing them from tipping over and colliding, reducing damage to the goods, and reducing the labor intensity of the workers.

[0007] In some embodiments, the barrier is fixedly connected to the cam for driving the cam to rotate.

[0008] In some embodiments, the top of the barrier is provided with a rotating handle for rotating the barrier.

[0009] In some embodiments, four clamping members are disposed around the cam; the clamping members include: A pressure plate is disposed within the cavity and located on the inner sidewall of the card block; A spring, disposed between the pressure plate and the inner wall of the locking block, is used to elastically reset the pressure plate; and A push pin is disposed on the pressure plate and faces the inner wall of the slide groove, for pressing against the inner wall of the slide groove; The cam presses against the pressure plate, and the pressure plate drives the ejector pin to press against the inner wall of the slide groove, thereby locking the block.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 3 and Figure 4A freight elevator includes: an elevator car 10 having a base plate 11 for carrying goods; a slide 20 disposed on the base plate 11; a slider 30 movably disposed within the slide 20; a plurality of rails 40 disposed on the slider 30 for intercepting goods; a locking block 50 disposed on the slider 30 and located within the slide 20; the locking block 50 having a cavity 511; a cam 60 rotatably disposed at the center of the cavity 511; and a clamping member 70 disposed around the cam 60 within the cavity 511 and passing through the wall of the locking block 50 against the inner wall of the slide 20. The cam 60 rotates to press the clamping member 70 against the inner wall of the slide 20, thereby locking the locking block 50.

[0014] It is understandable that the elevator car 10 is existing technology, and will not be described in detail here. The slide 20 is the track through which the barrier 40 moves within the elevator to block the movement of goods. For example, it can be a cross slide 20 set on the base plate 11, or something else. The slider 30 is a moving block that slides within the slide 20. For example, it can be a square slider 30, or a circular slider 30, etc., but is not limited to these. The barrier 40 is a component that limits the movement of goods. For example, it can be a combination of multiple columnar limiting barriers 40 to intercept goods, or a plate-shaped barrier 40 to limit the movement of goods, etc., but is not limited to these. The locking block 50 is a box-shaped frame for mounting the cam 60 and the clamping member 70. For example, it can be a square locking block 50, or a cylindrical locking block 50, etc., but is not limited to these. The cam 60 is a component that converts rotation into linear pushing motion on the clamping member 70. For example, it can be an eccentric circular cam 60, or an oval cam 60, etc., but is not limited to these. The clamping member 70 is a component that clamps the inner wall of the slide groove 20 to generate friction and lock the guardrail 40. For example, it can be a pin-type clamping member 70 or a block-type clamping member 70, but it is not limited to these.

[0015] As can be seen from the above, a slide 20 is provided on the elevator base plate 11. A movable locking block 50 and a guardrail 40 installed on the locking block 50 are installed in the slide 20. When the guardrail 40 needs to be moved, the cam 60 is rotated to release the guardrail 40. After the worker manually moves the guardrail 40 to the designated position, the cam 60 is rotated again to make the clamping member 70 press against the inner wall of the slide 20 to fix the guardrail 40. The guardrail 40 limits and fixes the goods, avoids the goods from tipping over and colliding, reduces the damage to the goods, and reduces the labor intensity of the workers.

[0016] Optionally, in some embodiments, please refer to Figure 2 At least two slide grooves 20 are provided. The slide grooves 20 are arranged in a cross shape within the base plate 11.

[0017] Understandably, the number and arrangement of the chutes 20 determine the running trajectory of the guardrail 40. For example, there can be two chutes 20 arranged in a cross shape in the base plate 11, or two parallel chutes 20, etc., but it is not limited to these.

[0018] This configuration, with the intersecting arrangement of multiple slots, allows the barrier 40 to restrict and secure various types of goods from more directions.

[0019] Optionally, in some embodiments, please refer to Figure 3 The barrier 40 is fixedly connected to the cam 60, which is used to drive the cam 60 to rotate.

[0020] It is understandable that the barrier 40 and the cam 60 are connected together, and the cam 60 rotates when the barrier 40 rotates. For example, the barrier 40 and the cam 60 can be welded together, or the barrier 40 and the cam 60 can be integrally formed, but it is not limited to these.

[0021] With this setup, the worker can rotate the barrier 40 to drive the cam 60 to rotate, resulting in a simple structure and convenient operation.

[0022] Optionally, in some embodiments, as shown in Figure 2, the top of the barrier 40 is provided with a rotating handle 41 for rotating the barrier 40.

[0023] Understandably, the rotating handle 41 is a component that makes it easier for workers to rotate the barrier 40. For example, it can be a key-shaped rotating handle 41 or a block-shaped rotating handle 41, but it is not limited to these.

[0024] With this configuration, workers can rotate the barrier 40 by turning the handle 41, making the operation simpler and less strenuous.

[0025] Optionally, in some embodiments, please refer to Figure 4 Four clamping members 70 are arranged around the cam 60. Each clamping member 70 includes: a pressure plate 71, disposed within the cavity 51 and located on the inner wall of the locking block 50; a spring 72, disposed between the pressure plate 71 and the inner wall of the locking block 50, for elastically resetting the pressure plate 71; and a push pin 73, disposed on the pressure plate 71 and facing the inner wall of the slide groove 20, for pressing against the inner wall of the slide groove 20. The cam 60 presses the pressure plate 71, and the pressure plate 71 drives the push pin 73 to press against the inner wall of the slide groove 20, locking the locking block 50 and thus locking the stop bar 40.

[0026] Understandably, spring 72 is a component that pushes pressure plate 71 back to its original position. For example, it can be a disc spring 72 or a cylindrical spring 72, but it is not limited to these. Cam 60 pushes pressure plate 71 forward, which in turn drives ejector pin 73 to press against the inner wall of slide groove 20. The component that fixes the stop bar 40 by the friction between ejector pin 73 and the inner wall of slide groove 20 can be, for example, a metal ejector pin 73 or an engineering plastic ejector pin 73, but it is not limited to these.

[0027] As can be seen from the above, after the worker moves the goods onto the elevator, the worker turns the rotary handle 41 to release the ejector pin, then moves the barrier 40 to the appropriate position, turns the rotary handle 41 again to press the ejector pin 73 against the inner wall of the slide groove 20, and fixes the barrier 40. This process is repeated until the movement of the goods is restricted from all directions.

[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
