Description

Technical Field

[0001] This utility model relates to a ladder, and more particularly to a ladder with a handle. Background Technology

[0002] In modern life, A-frame ladders are a common ladder tool widely used in home repairs, outdoor work, and other scenarios. Traditional A-frame ladders have the front of the steps hinged to the front leg, with the rear supported by a crossbar on the rear leg. Workers perform tasks on the steps. When the front and rear legs are extended, uneven force distribution can occur due to the worker's movements. Therefore, if a front or rear leg is not under load or even lifts up, the unloaded leg will retract towards the other leg, causing the ladder to automatically retract. If the unloaded leg then needs to regain load, the ladder can tip over, leading to accidents and even endangering the worker's safety.

[0003] In the prior art, a locking device is installed on the ladder to lock it in place when it is opened. However, traditional locking devices are complex in structure and operation, have high manufacturing costs, and are prone to damage. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a ladder with a handle that is compact in structure, low in manufacturing cost, simple to operate, has a good locking effect, and is easy to carry when folded.

[0005] This utility model provides a ladder with a handle, including an A-frame ladder. The A-frame ladder includes a front frame 11 and a rear frame 12. The upper ends of the front frame 11 and the rear frame 12 are hinged together and can be unfolded or folded. A foot platform 2 is hinged to the front frame 11, and a support rod 3 is provided on the rear frame 12. When unfolded, the support rod 3 contacts and supports the top foot platform 2. A handle 3 is hinged to the rear end of the foot platform 2. The handle 3 is provided with a buckle 42, which can lock the support rod 3 and fix the foot platform 2 to the support rod 3 when unfolded. When folded, the handle 3 is located at the top of the A-frame ladder.

[0006] This application designs the handle 3 as a structure with a buckle function. When unfolded, it can lock the support rod and securely lock the stepping platform to prevent the ladder from being accidentally retracted and ensure safety during use. When retracted, the handle is easy to carry and improves the convenience of use. Moreover, the structure is compact, the manufacturing cost is low, the operation is convenient and labor-saving, and the use effect is good.

[0007] Furthermore, the latching part 42 can latch onto the bottom of the support rod 3 and lock it in place; it directly contacts the bottom of the support rod 3, eliminating the need for additional structures on the support rod 3, resulting in a compact structure, low manufacturing cost, and good locking effect.

[0008] Furthermore, the handle 3 is L-shaped.

[0009] Furthermore, the handle 3 includes a connecting part 41 hinged to the rear end of the foot pedal platform 2. The rotation axis of the connecting part 41 is parallel to the rotation axis of the foot pedal platform 2. The end of the connecting part 41 is bent to one side to form the buckle part 42. It is easy to process and has low manufacturing cost.

[0010] Furthermore, the latching part 42 is inclined to the connecting part 41 and tends to move closer to the support rod 3 when locked; through the above structure, the locking force of the latching part 42 can be ensured, loosening can be avoided, and the locking reliability is high.

[0011] Furthermore, when locked, the connecting part 41 contacts the rear end face of the stepping platform 2. Through the above structural setting, the connecting part 41 can be supported when locked, so that the buckle part forms a clamping force and clamps onto the support rod 3, improving the locking stability and reliability, and ensuring that the ladder can remain stable when used at any angle.

[0012] Furthermore, the included angle between the connecting part 41 and the snap-fit ​​part 42 is greater than 60 degrees and less than 85 degrees, forming an acute angle structure, which in turn has a tendency to move closer to the support rod 3 when clamped, thus improving the clamping reliability.

[0013] Furthermore, the handle 3 is formed by bending a metal rod, which is convenient to process and has low manufacturing cost.

[0014] Furthermore, the handle 3 includes a first rod 421, the two ends of the first rod 421 are bent to the same side to form a second rod 423, the ends of the two second rods 423 are bent to the same side to form a third rod 411, the ends of the two third rods 411 are bent away from each other or towards each other to form a hinge 412, the two hinges 412 are coaxial, and the plane formed by the two third rods 411 is inclined to the plane formed by the two second rods 423. The structure is compact and has the functions of hinge, buckle and handle. It has high structural strength, low manufacturing cost and good use effect.

[0015] Furthermore, the center of the first rod 421 protrudes in the direction away from the second rod 423 to form a hook part 422, which facilitates unlocking and allows the ladder to be hung on the wall, ensuring stability during hanging and preventing it from tipping over.

[0016] This utility model relates to a ladder with a handle. The handle is designed with a snap-lock structure. When unfolded, it can lock onto the support rod and securely lock the stepping platform, preventing the ladder from being accidentally retracted and ensuring safety. When retracted, the handle is easy to carry, improving convenience. It requires no additional structure, has a compact structure, low manufacturing cost, is easy and labor-saving to operate, and has good performance. The snap-lock part is inclined to the connecting part, and when locked, the handle tends to move closer to the support rod, which can prevent the connecting part from accidentally loosening and ensure the locking force of the snap-lock part, resulting in high locking reliability. The handle is formed by bending a metal rod, resulting in a compact structure, high strength, low manufacturing cost, and good performance. This utility model of a ladder with a handle has an unfolding and locking function, high safety, convenient operation, low manufacturing cost, and good performance. Attached Figure Description

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] See Figures 1-10This utility model provides a ladder with a handle, including an A-frame ladder. The A-frame ladder includes a front frame 11 and a rear frame 12. The upper ends of the front frame 11 and the rear frame 12 are hinged, i.e., rotatably connected, so that they can be unfolded or folded. One or more step platforms 2 are hinged to the front frame 11. The step platforms 2 are connected by a linkage assembly and can rotate synchronously. The step platforms 2 are footboards for stepping on. Anti-slip textures are provided on the step platforms 2 to improve stepping safety and prevent slipping.

[0029] A support rod 3 is provided on the rear ladder frame 12. The support rod 3 is horizontally arranged, and there can be multiple support rods, which are part of the frame of the rear ladder frame 12.

[0030] When unfolded, the top support rod 3 contacts the top stepping platform 2, that is, the top of the top support rod 3 contacts the bottom of the top stepping platform 2, thereby supporting the top stepping platform 2. In this application, a handle 3 is hinged to the rear end of the stepping platform 2. The handle 3 is located at the center of the stepping platform 2 to prevent tilting when carried. A buckle 42 is provided on the handle 3. The buckle 42 can lock the support rod 3 in the unfolded state, restrict the rotation of the stepping platform 2, and thus lock and fix the stepping platform 2 to the support rod 3 to prevent the stepping platform 2 from being accidentally retracted and causing safety hazards. When retracted, the handle 3 is located at the top of the A-frame ladder, which is convenient for carrying and transporting.

[0031] This application designs the handle 3 as a structure with a buckle function. When unfolded, it can lock the support rod and securely lock the stepping platform to prevent the ladder from being accidentally retracted and ensure safety during use. When retracted, the handle is easy to carry and improves the convenience of use. It does not require additional structure, has a compact structure, low manufacturing cost, is easy and labor-saving to operate, and has good performance.

[0032] In this embodiment, the latching part 42 can latch onto the bottom of the support rod 3 and lock it in place. The latching part directly contacts the bottom of the support rod 3, eliminating the need for additional structures on the support rod 3, such as drilling. The structure is compact, the manufacturing cost is low, the locking effect is good, and the overall structural strength of the support rod is ensured.

[0033] The handle 3 is L-shaped. Specifically, the handle 3 includes a connecting part 41 hinged to the rear end of the foot platform 2. The rotation axis of the connecting part 41 is parallel to the rotation axis of the foot platform 2, that is, it is horizontally hinged. The end of the connecting part 41 is bent to one side (towards the support rod 3) to form a buckle part 42. The buckle part 42 and the connecting part 41 form an L-shaped structure, which is easy to process and has low manufacturing cost.

[0034] In order to improve the locking reliability and locking force, in this application, the latching part 42 is inclined to the connecting part 41. When locking, the handle 3 tends to move closer to the support rod 3, which can prevent the latching part 42 from accidentally loosening and ensure the locking force of the latching part 42, thus achieving high locking reliability.

[0035] In this embodiment, the handle 3 is hinged to the rear end face of the stepping platform and is a certain distance away from the bottom surface of the stepping platform. Therefore, when locking, the connecting part 41 contacts the rear end face of the stepping platform 2. At the same time, since the buckle is inclined to the connecting part, the rear end face of the stepping platform 2 supports the connecting part 41 when locking, so that the buckle forms a clamping force and clamps onto the support rod 3. This improves the locking stability and reliability, ensuring that the ladder remains stable when used at any angle. Preferably, the included angle between the connecting part 41 and the buckle 42 is greater than 60 degrees and less than 85 degrees, forming an acute angle structure. This results in a tendency to move closer to the support rod 3 when clamping, improving the clamping reliability.

[0036] The handle 3 in this application is formed by bending a metal rod. Specifically, the handle 3 includes a first rod 421, with both ends of the first rod 421 bent to the same side (in the same direction) to form two symmetrically arranged second rods 423. The ends of the two second rods 423 are bent to the same side (i.e., in the same direction) to form two symmetrical third rods 411. The ends of the two third rods 411 are bent away from each other or towards each other to form two symmetrical hinge parts 412. The two hinge parts 412 are coaxial. At the same time, a hinge seat is provided on the rear end face of the foot platform 2 to accommodate the insertion of the hinge part 412, realizing the rotational connection of the handle 3. The first rod and the second rod form a snap-fit ​​part, and the third rod 411 and the hinge... The first rod 421 forms a connecting part; and the plane formed by the two third rods 411 is inclined to the plane formed by the two second rods 423, that is, the buckle part and the connecting part form an angle. Its structure is compact and has the functions of hinge, buckle and handle. It has high structural strength, low manufacturing cost and good use effect. In order to avoid tilting when hanging on the wall or hanging by rope, in this application, the center of the first rod 421 protrudes away from (away from) the second rod 423 to form a hanging part 422. That is, the hanging part 422 is an arc rod structure. On the one hand, it is easy to unlock. On the other hand, it can hang the ladder on the wall or hang it by rope, and ensure the stability when hanging (loading) and prevent tilting.

[0037] This utility model relates to a ladder with a handle. The handle is designed with a snap-lock function. When unfolded, it can lock onto the support rod and securely lock the step platform, preventing accidental folding and ensuring safety. When folded, the handle is easy to carry, improving convenience. It requires no additional structure, is compact, has low manufacturing cost, is easy and labor-saving to operate, and performs well. The snap-lock part is inclined to the connecting part, and when locked, the handle tends to move closer to the support rod, preventing accidental loosening of the connecting part and ensuring high locking strength and reliability. The handle is formed by bending a metal rod, resulting in a compact and high-strength structure.

[0038] Moreover, it has low manufacturing costs and good performance; this utility model features a ladder with a handle and an unfolding and locking function.

[0039] It is highly safe to use, easy to operate, has low manufacturing costs, and good performance.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
