[0001] This utility model relates to the technical field of the catering industry, and in particular to a portable safety engineering ladder. Background Technology

[0002] In the daily operations of the catering industry, tasks such as equipment inspection, pipeline maintenance, and cleaning at heights are frequently involved. Portable safety ladders serve as auxiliary tools, providing convenient access for employees to climb to higher places. Whether it's cleaning exhaust ducts in the kitchen, inspecting ceiling wiring, or replacing lights and decorating in the dining area, their flexible mobility and easy storage make them suitable for various scenarios in catering establishments, including kitchens, dining areas, and storage rooms. They meet the operational needs in confined spaces, are readily available, and do not occupy excessive space, making them practical equipment for ensuring the efficiency of facility maintenance and operational safety in catering establishments, thus facilitating the smooth operation of daily catering business.

[0003] Currently, one type of portable safety ladder suffers from damage to its climbing bars after prolonged use. Since the climbing bars of existing ladders are fixed, the entire ladder must be replaced when damaged, which is limiting and impractical. Furthermore, in this type of portable safety ladder, the locking and pulling mechanisms for the second ladder are separate, making operation cumbersome and further limiting its practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the prior art, the climbing poles used for climbing will be damaged after long-term use. In existing engineering ladders, the climbing poles are fixed, and when they are damaged, they can only be replaced as a whole. The locking structure of the second climbing ladder and the pulling structure of the second climbing ladder are set separately, which is very troublesome during operation. Therefore, a portable safety engineering ladder is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable safety engineering ladder, comprising two first supports, each of the two first supports having a second support at one of its opposite ends, each of the two second supports having a limit block fixed at one of its opposite ends, each of the two first supports having a limit groove matching the limit block at one of its opposite ends, each of the two second supports and the first supports having multiple climbing rods, each of the two first supports and the two second supports having a connector fixed to its inner wall, each of the climbing rods having a locking block fixed at both ends, the locking block being engaged in the connector and fixed to the connector by bolts, one of the limit blocks having a connecting block fixed at one end away from the second support, one end of the connecting block penetrating the first support and having a support plate fixed thereon, the support plate having a locking structure for locking the position of the second support at a fixed point.

[0006] Preferably, the locking structure includes a fixing frame fixed to the outer wall of the support plate, a locking post is provided inside the fixing frame, one end of the locking post passes through the support plate and is movably inserted into the first bracket, a pull plate is fixed to the other end of the locking post, and a spring is fixed between the pull plate and the fixing frame on the outside of the locking post.

[0007] Preferably, a handle is fixed on one side of the fixing frame on the outer wall of the support plate, and the length of the handle is the same as the length of the locking post.

[0008] Preferably, a limiting plate is fixed to one end of the pull plate, a limiting post is slidably connected inside the limiting plate, one end of the limiting post is fixed to the fixing frame, and a baffle is fixed to the other end of the limiting post. A plurality of limiting holes matching the locking post are opened on the outer wall of one of the first brackets.

[0009] Preferably, a connecting plate is fixed on the outer wall of the support plate on one side of the pull plate, and a pin is provided in the connecting plate, the output end of the pin being inserted into the pull plate.

[0010] Preferably, rubber blocks are fixed to the opposite ends of the two first supports and the two second supports, and friction pads are fixed to the opposite ends of the two sets of rubber blocks. Velcro is fixed to the outer wall of the climbing pole, and an anti-slip sleeve is pasted on the outside of the Velcro. A movable groove matching the connecting block is opened on the outer wall of one of the first supports.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the use of connectors and locking blocks allows for easy replacement of damaged climbing poles by unscrewing bolts, separating the two locking blocks from their corresponding connectors. This eliminates the need for a complete replacement, enhancing practicality. Furthermore, when the second support needs to be moved, the user simply pulls the pull plate to disengage the locking pin from the limiting hole on the outer wall of the first support. The pull plate is then very close to the handle, allowing the user to simultaneously grasp both and move upwards, unfolding the second support. Once unfolded to the desired position, releasing the handle and pull plate allows the locking pin to retract into the corresponding limiting hole under the spring's restoring force, locking the second support in place. This integrated design allows the user to control both operations simultaneously, further enhancing practicality. Attached Figure Description

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a portable safety engineering ladder, including two first supports 1, each of the two first supports 1 having a second support 2 at one of its opposite ends, each of the two second supports 2 having a limit block 3 fixed at one of its opposite ends, each of the two first supports 1 having a limit groove 4 matching the limit block 3 at one of its opposite ends, each of the two second supports 2 and the first supports 1 having multiple climbing rods 5, each of the two first supports 1 and the two second supports 2 having a connector 6 fixed on its inner wall, each of the climbing rods 5 having a locking block 7 fixed at both ends, the locking block 7 being engaged in the connector 6 and fixed to the connector 6 by bolts, one of the limit blocks 3 having a connecting block 10 fixed at one end away from the second support 2, one end of the connecting block 10 passing through the first support 1 and fixed to a support plate 11, the support plate 11 having a locking structure 13 for locking the position of the second support 2 at a fixed point.

[0021] The overall effect of Embodiment 1 is that, through the setting of the limiting block 3 and the limiting groove 4, the movement position of the second support 2 can be limited to prevent it from detaching from the first support 1. Through the setting of the climbing pole 5, the user can climb by stepping on the climbing pole 5. Through the setting of the connecting piece 6 and the locking block 7, when the climbing pole 5 is damaged, the bolts can be unscrewed to separate the two locking blocks 7 from the two corresponding connecting pieces 6, so that the user can directly replace the damaged climbing pole 5 individually without replacing the whole thing, which is more practical. Through the setting of the locking structure 13, the position of the second support 2 can be locked, which makes it easy to adjust the distance of the second support 2 from the first support 1. Moreover, when the second support 2 of the device is not in use, it can be retracted into the first support 1, reducing its overall footprint and making it easy to carry.

[0022] Example 2, as Figure 1-4 As shown, the locking structure 13 includes a fixing frame 1301 fixed to the outer wall of the support plate 11. A locking post 1302 is provided inside the fixing frame 1301. One end of the locking post 1302 passes through the support plate 11 and is movably inserted into the first bracket 1. A pull plate 1303 is fixed to the other end of the locking post 1302. A spring 1304 is fixed between the pull plate 1303 and the fixing frame 1301, located outside the locking post 1302. A handle 17 is fixed to one side of the fixing frame 1301 on the outer wall of the support plate 11. The length of the handle 17 is the same as the length of the locking post 1302. A limiting plate 14 is fixed to one end of the pull plate 1303. A limiting post 15 is slidably connected inside the limiting plate 14. One end of the limiting post 15 is connected to the fixing frame 1302. 01 is fixed, and the other end of the limiting post 15 is fixed with a baffle 16. Multiple limiting holes 20 matching the locking post 1302 are opened on the outer wall of one of the first brackets 1. A connecting plate 18 is fixed on the outer wall of the support plate 11 on one side of the pull plate 1303. A pin 19 is provided in the connecting plate 18. The output end of the pin 19 is inserted into the pull plate 1303. Rubber blocks 21 are fixed at the opposite ends of the two first brackets 1 and the two second brackets 2. Friction pads 22 are fixed at the opposite ends of the two sets of rubber blocks 21. Velcro 8 is fixed on the outer wall of the climbing rod 5. Anti-slip sleeves 9 are pasted on the outside of the Velcro 8. A moving groove 12 matching the connecting block 10 is opened on the outer wall of one of the first brackets 1.

[0023] The effect achieved by the entire embodiment 2 is that when the second bracket 2 needs to be moved, the user only needs to pull the pull plate 1303 to disengage the locking pin 1302 from the limiting hole 20 on the outer wall of the first bracket 1. At this time, the position of the pull plate 1303 is very close to the position of the handle 17. The user can directly hold the handle 17 and the pull plate 1303 at the same time and move upward to drive the second bracket 2 to unfold. After unfolding to the appropriate position, the user only needs to release the handle 17 and the pull plate 1303, so that the locking pin 1302 enters the corresponding limiting hole 20 under the return thrust of the spring 1304, thereby locking the position of the second bracket 2. In operation, the device sets the pulling of the second bracket 2 and the locking structure 13 for controlling and locking the second bracket 2 together, so the user can control both to run at the same time without separate operation, which enhances its practicality. With the connection plate 18 and the pin 19, when the locking post 1302 is inserted into the limiting hole 20 and the position of the second bracket 2 is limited, the position of the pull plate 1303 can be locked by the pin 19 to prevent accidental shaking, making the locking of the second bracket 2 more stable and practical. With the anti-slip sleeve 9, the user is prevented from slipping when stepping on the climbing pole 5. With the Velcro 8, the damaged anti-slip sleeve 9 can be replaced individually. With the rubber block 21 and the friction pad 22, the rubber block 21 can deform according to the terrain such as the protrusions of the ground and the wall, making the support of the first bracket 1 and the second bracket 2 more stable. The friction pad 22 can increase the friction between the first bracket 1 and the second bracket 2 and the contact surface with the ground or wall, making the stability stronger.

[0024] Working principle: When using this device, due to the setting of connector 6 and locking block 7, when the climbing rod 5 is damaged, the two locking blocks 7 can be separated from the two corresponding connector 6 by unscrewing the bolts. The user can then directly replace the damaged climbing rod 5 individually without replacing the whole thing, making it more practical. In addition, when the second support 2 needs to be moved, the user only needs to pull the pull plate 1303 to make the locking post 1302 disengage from the limiting hole 20 opened on the outer wall of the first support 1. At this time, the position of the pull plate 1303 is very close to the position of the handle 17. The user can directly hold the handle 17 and the pull plate 1303 at the same time and move upward to drive the second support 2 to unfold. After unfolding to the appropriate position, simply release the handle 17 and the pull plate 1303 so that the locking post 1302 enters the corresponding limiting hole 20 under the reset thrust of the spring 1304, thereby locking the position of the second support 2.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
