Description
Technical Field
[0001] This utility model relates to a snap-fit locking structure for use in the field of storage batteries, and more specifically to a quick snap-fit locking structure and a detachable handle for lead-acid batteries having the same. Background Technology
[0002] Lead-acid batteries are generally quite heavy, so the use of handles makes it easier to move them, and ensuring the reliability of the handles is especially important.
[0003] Existing handles generally have the following problems: handles that are easy to install are also prone to falling off during use, posing a safety risk; while handles that are difficult to install, although they can effectively ensure that the handle does not fall off, are difficult to install during the production process, which leads to complaints from installation workers.
[0004] Therefore, how to design a new handle installation structure that is easy to install while also ensuring that the handle is not easy to fall off and increasing safety is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the present invention provides a quick-locking structure and a detachable handle for lead-acid batteries, aiming to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A quick-locking mechanism includes: a male connector and a female connector;
[0008] The male connector includes a male connector shaft, a variable diameter groove section, and an outwardly folded snap-fit protrusion formed coaxially in sequence. The outer diameter of the variable diameter groove section is smaller than the outer diameter of the male connector shaft and the outwardly folded snap-fit protrusion.
[0009] The female head has an insertion hole on one side that engages with the outward-folding snap-fit protrusion of the male head. The side wall of the female head has a limiting groove that engages with the outward-folding snap-fit protrusion. The outer diameter of the positioning part of the female head that is embedded in the variable diameter groove section is larger than the outer diameter of the male head shaft.
[0010] Through the above technical solution, the snap-fit locking structure provided by this utility model can use the outward snap-fit protrusion on the male end and the limiting slot on the female end to perform a limiting snap-fit engagement. It is only necessary to insert the female end into the direction of the male end, which can quickly achieve snap-fit, and it is not easy to fall out after connection, thus having stronger security.
[0011] Preferably, in the above-described quick-locking structure, the outward-facing snap-fit protrusion has an axial break, such that the outward-facing snap-fit protrusion includes multiple claws extending along the axial direction of the variable-diameter slot section. The break design allows the claws to elastically deform, providing safer and more reliable deformation performance during insertion.
[0012] Preferably, in the above-described quick-locking structure, the portion of the inner hole of the positioning part corresponding to the limiting groove is an inclined surface, and the inner hole of the inclined portion of the positioning part gradually decreases in the radial direction of the limiting groove. The inclined surface design makes it easier for the male and female connectors to deform under pressure during insertion.
[0013] Preferably, in the above-mentioned quick-locking structure, the male head has a groove on the end face near the outwardly folded locking protrusion, and the bottom wall of the female head's insertion hole has an elastic support protrusion, which is inserted into the groove. The cooperation between the elastic support protrusion and the groove allows the elastic support protrusion to provide support for the locking claw after insertion, preventing it from deforming and coming out under force.
[0014] Preferably, in the above-mentioned quick-locking structure, the number of elastic support protrusions is the same as the number of limiting slots, and they are arranged in a manner corresponding to the positions of the limiting slots, which can meet the corresponding insertion position matching requirements.
[0015] Preferably, in the above-mentioned quick-locking structure, the outwardly protruding part of the outwardly protruding locking protrusion is locked inside the limiting slot, thereby ensuring stronger structural stability after locking.
[0016] Preferably, in the above-mentioned quick-connect locking structure, the outwardly protruding portion of the outwardly protruding locking protrusion has a raised arc-shaped surface on the side facing the bottom wall of the insertion hole. The arc-shaped surface design is more conducive to the smoothness of insertion and does not affect the stability of insertion.
[0017] This utility model also provides a detachable handle for a lead-acid battery, including: a battery body and a handle; both sides of the battery body are provided with the above-mentioned quick-locking structure, the outer wall of the battery body is fixed to the end of the male rotating shaft away from the outward-folding locking protrusion, and the two male rotating shafts on both sides of the battery body are respectively connected to the shaft holes on the connecting ends on both sides of the handle.
[0018] Through the above technical solution, this utility model uses the above quick-connect locking structure to connect the battery body and the handle, which can ensure easy installation while ensuring that the handle is not easy to fall off, thus increasing safety.
[0019] Preferably, in the above-mentioned lead-acid battery detachable handle, the diameter of the handle's shaft hole is smaller than the outer diameter of the positioning part, which can prevent the handle from coming off.
[0020] Preferably, in the above-mentioned lead-acid battery detachable handle, the top surface of the battery body has a handle storage groove for accommodating the folded handle, which is beneficial for storing and hiding the handle after it is folded.
[0021] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a quick-locking structure and a detachable handle for a lead-acid battery. It can use the outward-facing locking protrusion on the male end and the limiting locking groove on the female end to achieve a limiting locking engagement. Simply insert the female end into the direction of the male end to quickly achieve a locking engagement. Using the above quick-locking structure to connect the battery body and the handle can ensure easy installation while preventing the handle from falling off, thus increasing safety.

[0040] The male connector 1 includes a male connector shaft 1-1, a variable diameter slot section 1-2, and an outwardly folded snap-fit protrusion 1-3, which are formed coaxially and sequentially. The outer diameter of the variable diameter slot section 1-2 is smaller than the outer diameter of the male connector shaft 1-1 and the outwardly folded snap-fit protrusion 1-3.
[0041] The female head 3 has an insertion hole 3-4 on one side that is inserted into the side of the outward-folding locking protrusion 1-3 of the male head 1. The side wall of the female head 3 has a limiting groove 3-3 that engages with the outward-folding locking protrusion 1-3. The outer diameter of the positioning part 3-1 embedded in the variable diameter groove section 1-2 of the female head 3 is larger than the outer diameter of the male head shaft 1-1.
[0042] To further optimize the above technical solution, the outward-folding snap-fit protrusion 1-3 has an axial break, so that the outward-folding snap-fit protrusion 1-3 includes multiple snap claws extending along the axial direction of the variable diameter snap groove section 1-2.
[0043] To further optimize the above technical solution, the part of the inner hole of the positioning part 3-1 corresponding to the limiting groove 3-3 is an inclined surface, and the radial direction of the inner hole of the inclined part of the positioning part 3-1 towards the limiting groove 3-3 gradually decreases.
[0044] To further optimize the above technical solution, a groove 1-4 is provided on the end face of the male head 1 near the side of the outward snap-fit protrusion 1-3, and an elastic support protrusion 3-2 is provided on the bottom wall of the insertion hole 3-4 of the female head 3, and the elastic support protrusion 3-2 is inserted into the groove 1-4.
[0045] To further optimize the above technical solution, the number of elastic support protrusions 3-2 is the same as the number of limiting slots 3-3, and they are arranged in a position corresponding to the limiting slots 3-3.
[0046] To further optimize the above technical solution, the outwardly protruding part of the outwardly folded-out protrusion 1-3 is locked inside the limiting slot 3-3.
[0047] To further optimize the above technical solution, the side of the outward-curved part of the outward-curved snap-fit protrusion 1-3 facing the bottom wall of the insertion hole 3-4 is a raised arc-shaped surface.
[0048] Example 2:
[0049] See appendix Figure 1 To be continued Figure 2 and attached Figure 4 This utility model discloses a detachable handle for a lead-acid battery, including: a battery body and a handle 2; both sides of the battery body are provided with a quick-locking structure according to embodiment 1, the outer wall of the battery body is fixed to the end of the male shaft 1-1 away from the outward-folding locking protrusion 1-3, and the two male shafts 1-1 on both sides of the battery body are respectively connected to the shaft holes 2-2 on the connecting ends 2-1 on both sides of the handle 2.
[0050] To further optimize the above technical solution, the diameter of the shaft hole 2-2 of the handle 2 is smaller than the outer diameter of the positioning part 3-1.
[0051] To further optimize the above technical solution, the top surface of the battery body has a handle storage groove for accommodating the folded handle 2.

[0054] During installation, first install the handle 2 onto the male shaft 1-1 through the shaft hole 2-2. Then, insert the female head 3 along the outward-facing locking protrusion 1-3. During insertion, the outward-facing locking protrusion 1-3 is compressed and deformed. As the female head 3 is inserted, the outward-facing locking protrusion 1-3 compresses and deforms the elastic support protrusion 3-2. As the female head 3 is fully inserted... Figure 9 As shown, the outward-folding snap-fit protrusion 1-3 enters the limiting snap-fit groove 3-3, the positioning part 3-1 enters the variable diameter snap-fit groove section 1-2, the outward-folding snap-fit protrusion 1-3 and the elastic support protrusion 3-2 restore their deformation, and finally the outward-folding snap-fit protrusion 1-3 enters the limiting snap-fit groove 3-3.
[0055] During the process of the outward-folding snap-fit protrusion 1-3 being squeezed and deformed and the elastic support protrusion 3-2 being squeezed and deformed, it is ensured that the outward-folding snap-fit protrusion 1-3 can smoothly enter the limiting slot 3-3;
[0056] like Figure 9 As shown, the outward-folding locking protrusion 1-3 and the elastic support protrusion 3-2 restore the deformation and lock the outward-folding locking protrusion 1-3 in the limiting slot 3-3. The female head 3 supports the connecting end 2-1 of the handle 2 to ensure that the handle 2 does not fall off.
