Description

Technical Field

[0001] This utility model relates to the field of devices that can be adsorbed onto smooth surfaces using the principle of vacuum negative pressure, and particularly to a gun-shaped suction cup. Background Technology

[0002] Adsorption devices utilizing the principle of vacuum negative pressure are widely used, including tool suction cups and handrail suction cups for bathrooms and toilets. Currently, existing technologies employ a vacuum principle, using the part of the handrail that contacts the wall as a suction cup. By removing the air from the space enclosed by the suction cup and the adsorption surface, the handrail is directly adsorbed onto the wall. These types of handrails require a negative pressure to be created between the suction cup and the outside atmosphere to adhere the suction cup to the surface, and the suction cup must be maintained in a vacuum negative pressure state at all times.

[0003] Chinese patent CN219078456U discloses a handheld electric suction cup, comprising: a connecting base, which is in the shape of an open ring or a closed ring; a rubber suction cup, which is installed below the connecting base; a first connecting vertical plate and a second connecting vertical plate, which are disposed opposite to each other on both sides of the connecting base; a grip, which is disposed laterally between the first connecting vertical plate and the second connecting vertical plate; a power supply and a vacuum pump, which are disposed on the first connecting vertical plate; a middle plate, which is installed on the second connecting vertical plate, and a gas guide channel communicating with the interior of the rubber suction cup is provided in the middle plate; a control switch, which is installed on the middle plate and electrically connected to the power supply and the vacuum pump; and a pressure relief mechanism, which is installed on the middle plate with an air pipe disposed in the grip and connected to the vacuum pump and the gas guide channel.

[0004] To maintain the vacuum negative pressure effect, the above-mentioned solutions generally require the use of an air pump for evacuation, and most of them also require a power supply to power the air pump, resulting in many components and a complex structure. In addition, power-driven handheld suction cups generally use a power supply to power the vacuum pump, and once the battery reaches the end of its lifespan and can no longer provide power, the handheld suction cup can no longer be used.

[0005] Therefore, there is an urgent need for a gun-shaped suction cup that can be attached to a smooth surface without the need for an air pump and power supply, and that makes it easier to remove the suction cup after use. It is simple in structure and easy to use.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to provide a gun-shaped suction cup, which uses the rotation of the gun-shaped suction cup trigger assembly to drive the displacement of the square rod of the rubber base, thereby creating a vacuum space between the rubber base and the smooth surface and allowing the suction cup to adhere to the smooth surface. It does not require the use of vacuum pumps and power supplies, and has a simple structure and is easy to use.

[0008] To achieve the above objectives, this utility model provides a gun-shaped suction cup, comprising at least: a gun-shaped housing, which is generally gun-shaped and has a semi-enclosed space at the barrel, and a locking hole on the barrel; a rubber base, which is disposed at the barrel opening and has a square rod extending into the barrel, with a tower-shaped spring sleeved on the square rod; in use, the rubber surface of the rubber base contacts a smooth external surface, and a vacuum space is formed between the rubber surface and the smooth external surface during the movement of the square rod, thereby adsorbing onto the smooth surface; a trigger assembly, which includes a trigger body and a spring clip assembled on the trigger body and a matching spring; the upper part of the trigger body is housed in the semi-enclosed space and is pin-connected to the square rod via a pin; the rotation of the trigger body drives the square rod to move, and while forming a vacuum space and adsorbing, the compressed spring clip gradually slides to the locking hole during the movement and is released and locked at the locking hole.

[0009] Furthermore, in the above technical solution, the locking hole on the gun housing is elliptical, and correspondingly, the shape of the bullet clip is adapted to the locking hole, and the inner side of the bullet clip has a limiting flange that can lock with the locking hole.

[0010] Furthermore, in the above technical solution, one end of the spring that is adapted to the spring clip abuts against the inside of the spring clip, and the other end abuts against the spring limiting groove provided on the trigger body; the spring is always in a compressed state before the spring clip enters the lock hole, and when the spring clip enters the lock hole, the spring force is released and pushes the spring clip out of the lock hole and locks it.

[0011] Furthermore, in the above technical solution, the free end of the square rod can pass through the bottom of the bowl-shaped muzzle frame of the gun housing, and is connected to the upper part of the trigger body by a pin.

[0012] Furthermore, in the above technical solution, the upper part of the trigger body may be provided with an abutting sliding part; while the trigger body rotates around the pin shaft, the abutting sliding part can slide along the outer side of the bowl bottom towards the center, thereby pulling the square rod, at which time the tower-shaped spring abutting the inner side of the bowl bottom is in a compressed state.

[0013] Furthermore, in the above technical solution, after the square rod is fully stretched to form a vacuum space, the spring clip slides into the lock hole and pops out to form a lock. At this time, the gun-shaped suction cup is adsorbed on the smooth surface and is in a working state. When it is necessary to remove the gun-shaped suction cup of this utility model, the spring clip is pressed into the lock hole, and the square rod can return to its original position under the restoring force of the tower spring. At this time, the gun-shaped suction cup is detached from the smooth surface and is in a non-working state.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1) This utility model uses the rotation of the gun-shaped suction cup trigger assembly to drive the displacement of the square rod of the rubber base, thereby creating a vacuum space between the rubber base and the smooth surface and allowing the suction cup to adhere to the smooth surface. It does not require the use of vacuum pumps or power supplies, and has a simple structure and is easy to use.

[0016] 2) This utility model, through the oval-shaped spring buckle and the matching lock hole, can prevent the two from rotating relative to each other after the spring buckle pops out from the lock hole. The cooperation with the upper limit flange of the spring buckle can better achieve the overall locking of the trigger assembly after the suction cup is adsorbed, which greatly improves the safety in the adsorption state.

[0017] 3) The rotation of the trigger assembly of this utility model utilizes the lever principle. That is, the rotation of the trigger body causes the sliding part of the pointed structure to slide downward, thereby pulling the square rod. A small "pulling" force can effectively pull the square rod to create the required vacuum space.

[0018] 4) When it is necessary to remove the gun-shaped suction cup of this utility model, the spring clip can be pressed into the locking hole. At this time, the square rod can return to its original position under the restoring force of the tower spring. The vacuum space formed during adsorption disappears, and the gun-shaped suction cup can be detached from the smooth surface. Therefore, the entire detachment process can be achieved by pressing the spring clip once, which is convenient to operate.

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0027] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprising" shall be understood to include the stated elements or components without excluding other elements or other components.

[0028] In this document, for ease of description, spatial relative terms such as “below,” “under,” “down,” “above,” “above,” “upper,” etc., are used to describe the relationship of one element or feature to another element or feature in the accompanying drawings. It should be understood that spatial relative terms are intended to encompass different orientations of an object in use or operation, in addition to those depicted in the figures. For example, if an object in the figure is flipped, an element described as “below” or “under” another element or feature would be oriented “above” that element or feature. Thus, the exemplary term “below” can encompass both the downward and upward orientations. An object may also have other orientations (rotated 90 degrees or other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0029] In this document, the terms "first," "second," etc., are used to distinguish two different elements or parts, and are not used to define specific positions or relative relationships. In other words, in some embodiments, the terms "first," "second," etc., can also be used interchangeably.

[0030] As shown in Figures 1 to 4, this utility model provides a gun-shaped suction cup, which includes at least a gun-shaped housing 1, a trigger assembly 2, and a rubber base 3. The gun-shaped housing 1 has an overall gun-shaped appearance (see reference). Figure 1-A and Figure 1-BThe barrel has a semi-enclosed space, meaning the upper part of the barrel is closed and the lower part is open, to allow for the installation of the trigger assembly 2 and to provide room for the rotation of the trigger assembly 2; a locking hole 11 is provided on the barrel. A rubber base 3 is located at the barrel opening and has a recess that extends into the barrel (i.e.,... Figure 3-A , 3-B A square rod 31 extends from the right side, and a tower-shaped spring 32 is fitted onto the square rod 31. In use, the rubber surface of the rubber base 3 contacts a smooth external surface (see reference). Figure 1-A and 1-B During the movement of the square rod 31 (that is, towards...), Figure 3-A (Moving to the right), a vacuum space can be formed between the rubber surface and the smooth external surface, thereby allowing the rubber base 3 of the gun-shaped suction cup of this application to adhere to the smooth surface. The trigger assembly 2 includes a trigger body 20 and a spring clip 21 and a matching spring 22 assembled on the trigger body 20; the upper part of the trigger body 20 is housed in the semi-enclosed space of the aforementioned housing, and can be pinned to the square rod 31 via a pin 23; the rotation of the trigger body 20 (refer to...) Figure 3-A The arrow direction) can drive the square rod 31 to move (that is, towards) Figure 3-A (Moving to the right) As a vacuum space is formed between the rubber surface and the smooth surface, and a suction cup is formed for adsorption, the spring buckle 21, which is under compression by the spring 22, can gradually slide to the lock hole 11 during the movement and release and lock at the lock hole 11. This process can be referred to Figures 1-A to 1-B The process of change: Figure 1-A In the state before adsorption, the cartridge clip 21 is squeezed into the semi-enclosed space of the gun housing 1; Figure 1-B In the state after adsorption, the snap 21 moves to the lock hole 11, the elastic force of the spring 22 is released, and the snap 21 is ejected from the lock hole 11.

[0031] Further as Figure 1-A and 1-B As shown, the locking hole 11 on the gun housing 1 is elliptical. Correspondingly, the shape of the spring clip 21 is adapted to the locking hole 11. The inner side of the spring clip 21 has a limiting flange 211 that can be engaged with the locking hole 11 (see reference). Figure 2 and Figure 4-A The oval-shaped spring clip and the matching locking hole prevent rotation after the spring clip pops out of the locking hole, thus better achieving overall locking of the trigger assembly 2 after suction cup adsorption (i.e., Figure 1-B Specifically, one end of the spring 22, which is adapted to the spring clip 21, abuts against the inside of the spring clip, and the other end abuts against the spring limiting groove 202 provided on the trigger body 20 (see reference). Figure 2 and Figure 4-A , Figure 4-BThe spring 22 is always in a compressed state before the snap 21 enters the lock hole 11. When the snap 21 slides into the lock hole 11, the spring force of the spring 22 is released and pushes the snap 21 out of the lock hole 11 to lock it.

[0032] Further as Figure 2 , Figure 3-A and 3-B As shown, the free end of the square rod 31 passes through the bottom of the bowl-shaped muzzle 12 frame of the gun housing 1, and is connected to the upper part of the trigger body 20 by a pin 23. Further, preferably but not restrictively, the upper part of the trigger body 20 is provided with an abutting sliding part 201; while the trigger body 20 rotates around the pin 23, the abutting sliding part 201 slides along the outer side of the bowl bottom towards the center. At this time, the trigger body 20 is actually a lever structure. The rotation of the trigger body 20 causes the pointed abutting sliding part 201 to slide downward, thereby pulling the square rod 31. At this time, the tower-shaped spring 32 abutting against the inner side of the bowl bottom is in a compressed state. Under the action of the pull, the aforementioned "vacuum space" can be formed in the middle of the rubber base 3, thereby realizing the adsorption of the suction cup.

[0033] As further shown in Figures 1 to 4, after the square rod 31 of this utility model is fully pulled and a vacuum space is formed, the spring clip 21 slides into the lock hole 11 and pops out to form a lock. At this time, the gun-shaped suction cup is adsorbed on the smooth surface and is in working state. When it is necessary to remove the gun-shaped suction cup of this utility model, the spring clip 21 can be pressed into the lock hole 11. At this time, the square rod 31 can return to its original position under the restoring force of the tower spring 32 (the vacuum space disappears), and the gun-shaped suction cup can be detached from the smooth surface and is in non-working state.

[0034] The usage process of the gun-shaped suction cup after assembly of this utility model is as follows:

[0035] according to Figure 1-A The rubber base 3 of the gun-shaped suction cup of this utility model is pressed onto a smooth surface in a certain manner; according to Figure 3-A The arrow direction "pulls" the trigger body 20 of the trigger assembly 2. At this time, the trigger body 20 rotates counterclockwise around the pin 23, causing the abutment sliding part 201 on the upper part of the trigger body 20 to move along... Figure 3-A Slide down as shown, until... Figure 3-B At the position shown, the square rod 31 is pulled towards the right side of the figure until the spring clip 21 on the trigger assembly 2 slides into the locking hole 11 of the housing 1 and is ejected, thus locking the entire trigger assembly 2 (i.e., Figure 3-B (Illustrated state), at this time the limiting flange 211 on the spring clip 21 is engaged inside the lock hole 11 (reference). Figure 4-A and Figure 4-BSince both the spring clip and the locking hole are elliptical, they cannot rotate relative to each other, ensuring a secure lock. At this point, the gun-shaped suction cup of this invention can firmly adhere to the smooth surface and is in working condition. When it is necessary to remove the gun-shaped suction cup, the spring clip 21 can be forcefully pressed into the locking hole 11. At this time, the square rod 31 can return to its original position under the restoring force of the tower spring 32. The vacuum space formed during suction disappears, and the gun-shaped suction cup can detach from the smooth surface and enter a non-working state.

[0036] The gun-shaped suction cup of this invention does not require a vacuum pump or power supply. It has a simple structure and is easy to use. It can be used as a suction cup tool for smooth surfaces such as glass.

[0037] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical applications, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. Any simple modifications, equivalent changes, and alterations made to the foregoing exemplary embodiments should fall within the protection scope of the present invention.
