Description

Technical Field

[0001] This invention relates to the field of hook technology, and more specifically, to a pop-out hook. Background Technology

[0002] Hooks are widely used in automotive interiors, home storage, and other fields. Among them, pop-up hooks are favored because they can retract when not in use, keeping surfaces clean. Most existing pop-up hooks use spring-driven pop-out mechanisms, such as the patent with publication number CN223266708U, which uses an internal push-type lock cylinder (like a ballpoint pen lock cylinder) to achieve locking and unlocking in the telescopic state.

[0003] However, the above has a drawback: the hook lacks an effective damping mechanism when it pops out or retracts under the action of the spring. This means that the hook's movement speed is entirely determined by the spring force, often resulting in sudden, rapid popping out or violent retraction. This uneven movement speed severely affects the user's operating feel and reduces the perceived quality of the product.

[0004] Therefore, how to make the hook move at a uniform speed and smoothly during the pressing and extending process is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The main objective of this invention is to provide a pop-up hook that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A pop-out hook includes a hook body, a hook housing, and a hook base. The hook body is movably disposed inside the hook housing, and the hook housing is fixed together with the hook base. A lock cylinder is installed inside the hook body to limit the travel of the hook body when it is pressed. The hook body includes a hook base, and a plurality of limiting ridges are provided on the outer wall of the hook base along its extension direction. A guide groove is provided on the inner circumference of the hook housing, and a damping block is fitted on the limiting ridge and can slide in the guide groove.

[0008] Preferably, the hook base is integrally provided with a hooking part at the end, the hooking part extends out from the upper end of the hook housing, and the end of the hooking part is integrally provided with a limiting part.

[0009] Preferably, the lock cylinder includes a lock cylinder housing and a lock cylinder inner core. The lock cylinder inner core is movably fitted inside the lock cylinder housing. Lock tongues are integrally provided on both sides of the lock cylinder housing. The bottom end of the lock cylinder inner core is integrally provided with hooks that are inclined to both sides. When the hooks move, they can abut against the hooks and protrude outwards.

[0010] Preferably, a guide post is fixed to the top of the lock cylinder housing, and the guide post is movably inserted into the guide hole provided at the top of the lock cylinder inner core. A spring II is also sleeved on the guide post.

[0011] Preferably, the inner core of the lock cylinder is provided with grooves on both sides, and a pair of wedges are provided in the grooves. The grooves, wedges and the inner wall of the lock cylinder housing form a slide. A connecting hook is also rotatably installed on the top of the inner core of the lock cylinder housing. When the lock cylinder housing and the inner core of the lock cylinder extend and retract relative to each other, the connecting hook slides in the slide.

[0012] Preferably, the hook base has an integrally formed inner cavity, with lock holes on both sides of the inner cavity. When the lock tongue protrudes outward, it engages with the lock hole to complete the locking.

[0013] Preferably, the hook base is integrally provided with a latch, and the hook is engaged with the latch.

[0014] Preferably, the surface of the lock cylinder housing is provided with a limiting groove, and the surface of the lock cylinder inner core is integrally provided with a limiting block, which is slidably disposed in the limiting groove.

[0015] Preferably, a spring I is fitted between the hook body and the hook base.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention utilizes a damping block fitted onto the limiting ridge of the hook base, allowing the damping block to slide within a guide groove on the hook housing. During the extension and retraction of the hook body driven by spring I, a continuous sliding friction force is generated between the damping block and the inner wall of the guide groove, creating an effective damping effect. This damping force smooths out instantaneous fluctuations in spring force, preventing the hook from suddenly and rapidly popping out or violently retracting due to excessive spring force. This ensures that the hook's movement speed remains uniform and smooth, significantly improving the user's pressing and popping operation feel. The hook body does not violently impact the housing at the end of its extension / retraction stroke, thus eliminating the "clicking" noise caused by rapid popping out of traditional hooks and enhancing the product's perceived quality.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1-3 , Figure 5 , Figure 7As shown, to address the problem of uneven pop-out speed of existing hooks, a pop-out hook is provided, including a hook body 1, a hook housing 2, and a hook base 3. In specific settings, it can be made of plastic or metal to meet the strength and service life requirements of different scenarios. The hook body 1 is movably disposed inside the hook housing 2, and the hook body 1 is nested inside the hook housing 2. The end of the hook body 1 passes through one end of the hook housing 2. The hook housing 2 and the hook base 3 are fixed together, which can be fixed by snap-fit ​​connection, threaded connection, or bolt. In this embodiment, a screw connector 202 is used for docking, and then screws are used to fix them together.

[0033] A lock cylinder 5 is installed inside the hook body 1. The lock cylinder 5 is used to limit the stroke of the hook body 1 when it is pressed. The hook body 1 includes a hook base 103. The outer wall of the hook base 103 is provided with a plurality of limiting ridges 104 distributed along its extension and retraction direction. The inner circumference of the hook shell 2 is provided with a guide groove 201. After the damping block 4 is fitted on the limiting ridge 104, it can slide in the guide groove 201. The damping block 4 is made of rubber and is nested in the guide groove 201. It slides and rubs against the inner wall of the guide groove 201. By making a damping block 4 of a predetermined size, it can match the guide groove 201. Thus, when the hook body 1 extends and retracts, the damping block 4 and the guide groove 201 form a damping effect, so that the hook pops out at a uniform speed and improves the feel.

[0034] like Figure 6 As shown, in order to prevent the hung items from falling off, the hook base 103 is integrally provided with a hooking part 101 at the end. The hooking part 101 extends out from the upper end of the hook housing 2, and the end of the hooking part 101 is integrally provided with a limiting part 102. The diameter of the limiting part 102 is larger than that of the hooking part 101, which can block the items on the hooking part 101 and prevent them from falling off.

[0035] like Figure 4 , Figure 8 , Figure 9 As shown, in a specific configuration, the lock cylinder 5 includes a lock cylinder housing 501 and a lock cylinder inner core 503. The lock cylinder inner core 503 is movably fitted inside the lock cylinder housing 501. Lock tongues 504 are integrally provided on both sides of the lock cylinder housing 501. The bottom end of the lock cylinder inner core 503 is integrally provided with hooks 5031 that are inclined to both sides. When the hooks 5031 move upward, they can abut against the hooks 5031 and protrude outward. The hooks 5031 are distributed in a figure-eight shape. When the lock cylinder inner core 503 retracts into the lock cylinder housing 501, the outer shoulder of the hooks 5031 can abut against the lock tongue 504 and protrude outward.

[0036] A guide post 506 is fixed on the top of the lock cylinder housing 501. The guide post 506 is movably inserted into the guide hole 5033 provided on the top of the lock cylinder inner core 503. A spring II 505 is also sleeved on the guide post 506. The spring II 505 is used to push the lock cylinder housing 501 to move upward relative to the lock cylinder inner core 503 and reset.

[0037] To further illustrate the operation of lock cylinder 5, Figure 9 , Figure 10 For example, the inner core 503 of the lock cylinder has symmetrically arranged grooves 5034 on both sides, and a pair of wedges 5035 are arranged in the grooves 5034. The grooves 5034, wedges 5035 and the inner wall of the lock cylinder housing 501 form a slide 5036. The wedges 5035 include upper and lower irregular blocks. The slide 5036 is formed between the two irregular blocks and on the left and right sides of the two irregular blocks. A connecting hook 502 is also rotatably installed on the top of the lock cylinder housing 501. When the lock cylinder housing 501 and the inner core 503 extend relative to each other... When the connecting hook 502 slides within the slide rail 5036, and the inner core 503 of the lock cylinder is pushed by pressing the end of the hook body 1, the connecting hook 502 moves along the right wall of the groove 5034 to between the two irregular blocks. After being released, the bottom end of the connecting hook 502 hooks the upper irregular block of the wedge block 5035. When the hook body 1 is pressed again, the bottom end of the connecting hook 502 moves along the left wall of the groove 5034 to the end of the upper irregular block of the wedge block 5035 under the guidance of the lower irregular block of the wedge block 5035, thus completing the reset.

[0038] like Figure 6 As shown, the hook base 103 has an integrated inner cavity 105. Locking holes 106 are opened on both sides of the inner cavity 105. When the locking tongue 504 protrudes outward, it is locked into the locking hole 106, thereby limiting the stroke of the hook body 1 and realizing the extension and retraction of the hook body 1.

[0039] like Figure 4 As shown, a latch 301 is integrally provided on the hook base 3, and the hook 5031 is locked on the latch 301 to keep the relative position of the lock cylinder inner core 503 unchanged, thereby restricting the extension and retraction of the hook body 1.

[0040] like Figure 8 As shown, a limiting groove 5011 is provided on the surface of the lock cylinder housing 501, and a limiting block 5032 is integrally provided on the surface of the lock cylinder inner core 503. The limiting block 5032 is slidably disposed in the limiting groove 5011 to keep the lock cylinder inner core 503 stable when it moves in the lock cylinder housing 501.

[0041] like Figure 2 As shown, a spring I6 is fitted between the hook body 1 and the hook base 3 to push the hook body 1 to pop out.

[0042] The usage process of this hook is as follows:

[0043] 1. Press the hook body 1 so that the hook body 1 retracts into the hook housing 2 until it can no longer retract, and the lock cylinder 5 gradually enters the inner cavity 105;

[0044] 2. During the process of the inner cavity 105 moving down and pressing down the lock cylinder 5, the inner core 503 of the lock cylinder cannot move down because the hook 5031 is stuck on the latch 301, and thus gradually retracts into the lock cylinder housing 501. During this process, the outer shoulder of the hook 5031 presses against the latch 504 and protrudes outward, so that the latch 504 enters the lock hole 106. At the same time, the bottom end of the connecting hook 502 enters between the upper and lower parts of the wedge 5035. After the pressing action is released, the bottom end of the connecting hook 502 hooks the upper part of the irregular block of the wedge 5035, and completes the locking, thereby limiting the stroke of the hook body 1 and realizing the retraction of the hook body 1.

[0045] 3. Press the hook body 1 again until it can no longer retract and then release it. Under the guidance of the lower part of the irregular block of the wedge block 5035, the bottom end of the connecting hook 502 moves along the left side of the groove 5034 to the end of the upper part of the irregular block of the wedge block 5035. At this time, the lock cylinder housing 501 and the lock cylinder inner core 503 move away from each other and are reset under the action of the spring II 505. At the same time, the outer shoulder of the hook 5031 can no longer press against the lock tongue 504 and protrudes outward, so that the lock tongue 504 exits from the lock hole 106. The hook body 1 is pushed out and reset by the spring I 6.

[0046] 4. During the extension and retraction of the hook, the damping block 4 and the guide groove 201 form a damping effect, which makes the hook pop out at a uniform speed and improves the feel.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
