Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an elevator guardrail connection structure. Background Art

[0002] Freight elevators installed on some construction sites and mines need to have guardrails installed at the elevator entrance to prevent cargo from falling from the elevator when unattended.

[0003] At present, a Chinese utility model with publication number: CN212893381U discloses a clamping connection structure of an elevator car top guardrail, including a car top, a plurality of vertical bars are evenly fixedly installed on the top wall of the car top, and a plurality of cross bars are commonly connected to the vertical bars on the same side, and each of the cross bars is movably connected to a plurality of connecting blocks that cooperate with the vertical bars, and the connecting blocks correspond to the vertical bars one by one, and each of the connecting blocks is provided with a clamping and fixing device that cooperates with the vertical bars. In this utility model, after the vertical bars are evenly installed on the car top, the cross bars are evenly connected to the vertical bars, and the cross bars can be conveniently and quickly fixedly connected to the vertical bars by using the connecting blocks, which is not only convenient to install, but also has good installation stability.

[0004] Existing elevator guardrails include double-door guardrails, which are convenient to open and close. However, the guardrail connection structure is fixed by a snap-on method, which generates vibrations during the up and down movement of the elevator, making it very easy for the guardrail connection structure to fall off, causing the guardrail to open accidentally. Using a lock to lock the guardrail makes it more troublesome to open and close the guardrail, which results in the low practicality of the existing elevator guardrail connection structure. For this reason, we propose an elevator guardrail connection structure. Utility Model Content

[0005] The purpose of the utility model is to provide an elevator guardrail connection structure, which has the advantages of being easy to stably clamp and connect the elevator guardrail, improving the convenience of operation, and facilitating the up and down adjustment of the height of the guardrail connection structure, so as to facilitate personnel to access the operation function.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an elevator guardrail connection structure, including a fixed frame, guardrail plates are hinged on both sides of the fixed frame, and sliding grooves are opened on the sides of the two guardrail plates close to each other, and the ends of the two guardrail plates close to each other are slidably connected with a fixed cylinder and a fixed rod through the sliding grooves, and the end of the fixed rod close to the fixed cylinder is fixedly connected with an insertion cylinder, and the end of the fixed cylinder close to the fixed rod is slidably connected with an insertion rod slidably plugged into the insertion cylinder, the interior of the fixed cylinder is fixedly connected with a second spring fixedly connected to the insertion rod, and the interior of the insertion rod close to one end of the insertion cylinder is symmetrically fixedly connected with two telescopic rods, and the surfaces of the two telescopic rods are fixedly sleeved with third springs, and the ends of the two telescopic rods away from the insertion rods are fixedly connected with blocks slidably plugged into the insertion cylinder.

[0007] By adopting the above technical solution, the elastic force of the second spring and the third spring is used to drive the plug rod and the block to slide out of the insertion tube, so that the two guardrail plates are connected. This can not only improve the stability of the elevator guardrail connection and prevent it from detaching. At the same time, the elevator guardrail can be opened by pressing the block and then retracting the plug rod, which is convenient for actual operation; the height of the fixed tube and the fixed rod is adjusted by pulling the fixed tube and the fixed rod outward to overcome the elastic force of the first spring, and then the rebound force of the first spring is used to drive the first tooth to re-enter the second tooth to fix the height of the fixed tube and the fixed rod. The effect of facilitating the adjustment of the height of the elevator guardrail connection structure is achieved, thereby facilitating the access and operation of personnel and improving practicality.

[0008] The utility model is further configured as follows: both sides of the fixed cylinder and the fixed rod are fixedly connected with a first spring fixedly connected to the guardrail plate, the surfaces of the fixed cylinder and the fixed rod are slidably sleeved with a sliding sleeve, the ends of the fixed cylinder and the fixed rod away from each other are fixedly connected with a first tooth, and the sides of the two sliding grooves away from each other are fixedly connected with a second tooth engaged with the first tooth.

[0009] The above technical solution is adopted to facilitate the adjustment of the height of the elevator guardrail connection structure, thereby facilitating different access operations for personnel and improving practicality.

[0010] The utility model is further configured as follows: a fixing plate is fixedly sleeved on the surface of the inserting rod.

[0011] By adopting the above technical solution, it is easy to move the fixing plate to drive the insertion rod to slide out from the inside of the insertion tube.

[0012] The utility model is further configured as follows: one end of the insertion rod close to the insertion tube is arc-shaped.

[0013] The adoption of the technical solution makes it easy to insert the insertion rod into the interior of the insertion tube.

[0014] The utility model is further configured as follows: the interiors of the two guardrail plates are both opened and fixedly installed with protection nets.

[0015] By adopting the above technical solution, the interior of the elevator can be ventilated and garbage and debris can be prevented from entering the interior.

[0016] The utility model is further configured as follows: one side of the two guardrail plates is fixedly connected with a handle.

[0017] By adopting the above technical solution, it is convenient to pull the handle to drive the two guardrail panels to rotate and open.

[0018] The utility model is further configured as follows: welding plates are fixedly connected to both sides of the surface of the fixed frame.

[0019] By adopting the above technical solution, the fixed frame is welded and fixed at the entrance of the elevator by using a welding plate, so that the elevator guardrail can protect the elevator entrance.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. By using the elastic force of the second spring and the third spring to respectively drive the plug rod and the card block to slide out of the inside of the plug tube, the two guardrail plates are connected, which can not only improve the stability of the elevator guardrail connection and prevent it from detaching. At the same time, the elevator guardrail can be opened by only pressing the card block and then retracting the plug rod, which is convenient for actual operation;

[0022] 2. The height of the fixing cylinder and the fixing rod is adjusted by pulling the fixing cylinder and the fixing rod outward to overcome the elastic force of the first spring, and then the first tooth is driven to re-engage the second tooth by the rebound force of the first spring to fix the height of the fixing cylinder and the fixing rod. This achieves the effect of facilitating the adjustment of the height of the elevator guardrail connection structure, thereby facilitating the operation of personnel and improving practicality.
