Description

Technical Field

[0001] This utility model relates to a suction device. Background Technology

[0002] A suction holder is a device used to hold building materials and other items, especially those with flat surfaces. Currently used suction holders require the user to hold the handle firmly after the item is attached, and then operate a control switch to lock the handle, maintaining constant attachment. However, in some situations, such as when the user can only use the suction holder with one hand, locking the handle with one hand is not possible, making it inconvenient. Utility Model Content

[0006] The grip handle is provided with a receiving groove and a notch communicating with the receiving groove;

[0007] A tensioning handle is rotatably mounted in the receiving groove, and the tensioning handle includes a first snap-fit ​​part, a first connecting part, and a first pressing part that are interconnected.

[0008] The cover includes a side wall and a bottom, the bottom being connected to one end of the side wall and to one end of the grip handle, and the bottom having a clearance hole communicating with the receiving groove;

[0012] A first elastic element connects the switch and the grip handle, and the first elastic element applies an elastic force to the switch to rotate in a first direction;

[0013] Wherein, after the first locking part rotates along the first direction and drives the second locking part to rotate at a certain angle, the first locking part disengages from the second locking part, and the second locking part automatically rotates and resets in the first direction under the action of the first elastic member to a position that can restrict the first locking part from rotating in the opposite direction to the first direction.

[0014] In some embodiments, the first snap-fit ​​portion includes a first arcuate surface and a first flat surface that are connected to each other; the second snap-fit ​​portion includes a second arcuate surface and a second flat surface that are connected to each other;

[0015] When the first locking part rotates along the first direction, the first arc-shaped surface slides along the second arc-shaped surface and drives the second locking part to rotate at a certain angle. After the first arc-shaped surface separates from the second arc-shaped surface, the second locking part rotates in the first direction to reset until the first plane contacts the second plane.

[0016] In some embodiments, it also includes:

[0017] A second elastic element is installed between the elastic adsorption element and the bottom, and the second elastic element applies an elastic force to the elastic adsorption element to keep it away from the bottom.

[0020] In some embodiments, the first snap-fit ​​portion includes a third side plate and a fourth side plate of the same shape and size, wherein the third side plate is an extension of the first side plate and the fourth side plate is an extension of the second side plate.

[0021] In some embodiments, it also includes:

[0022] A reinforcing sheet is installed inside the elastic adsorption member and connected to the connector.

[0023] In some embodiments, the tensioning handle is an integral structure; and / or, the switch is an integral structure.

[0024] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0025] The positive and progressive effects of this utility model are as follows: when it is necessary to use the suction device of this utility model to hold an object with one hand, one only needs to hold the handle with one hand to attach the elastic suction element to the object, and then hook the first pressing part of the tightening handle with the fingers of that hand to make it rotate in the direction close to the handle (first direction), which can automatically complete the switch to lock the tightening handle, thereby ensuring that the elastic suction element always adheres to the object.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] It should be noted that in the claims and specification of this patent, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0033] like Figures 1-5 As shown, this embodiment discloses a suction device, which includes a grip handle 1, a tension handle 2, a cover 3, an elastic suction element 4, a connector 5, a switch 6, and a first elastic element.

[0034] The handle 1 is an L-shaped handle with a receiving groove 11 on one side. A notch 12 communicating with the receiving groove 11 is opened on the bottom 32 of the groove 11, and the notch 12 is located at the corner of the L-shape.

[0035] The tensioning handle 2 is rotatably installed in the receiving groove 11. The tensioning handle 2 includes a first snap-fit ​​part 21, a first connecting part 22 and a first pressing part 23 that are connected to each other. In order to realize the rotation of the tensioning handle 2 in the mounting groove of the grip handle 1, the first snap-fit ​​part 21 or the first connecting part 22 or the first pressing part 23 can be connected to the side of the groove of the receiving groove 11 by means of a rotating shaft.

[0036] In this embodiment, the cover 3 is a flat-bottomed bowl-shaped structure, which includes an annular sidewall 31 and a generally circular bottom 32. The bottom 32 is connected to one end of the sidewall 31 and to one end of the handle 1, and an avoidance hole 321 communicating with the receiving groove 11 is provided on the bottom 32. However, in other embodiments, the bottom 32 of the cover 3 may also be rectangular, polygonal or other irregular shapes.

[0037] The elastic adsorption member 4 is connected to the side wall 31 and covers the opening of the cover. In this embodiment, the elastic adsorption member 4 is installed on the inner side of the side wall 31 of the cover 3 and extends to the outer side, and a hollow interlayer is formed between the elastic adsorption member 4 and the bottom 32 of the cover 3.

[0038] One end of the connector 5 is connected to the elastic adsorption member 4, and the other end passes through the clearance hole 321 and is connected to the first connecting part 22 of the tensioning handle 2.

[0039] The switch 6 is rotatably mounted in the receiving groove 11 and exposed in the notch 12. The switch 6 includes a second latching part 61, a second connecting part 62 and a second pressing part 63 connected from top to bottom. The second latching part 61 can be latched and locked with the first latching part 21, that is, the handle 2 can be locked and unlocked by the switch 6.

[0040] The first elastic element (not shown in the figure) connects the switch 6 and the grip handle 1. The first elastic element applies force to the switch 6 in a first direction (in... Figure 2 The elastic force that rotates clockwise (in the middle).

[0041] Specifically, rotating the tensioning handle 2 causes its first engaging portion 21 to rotate in a first direction. The first engaging portion 21 then contacts the second engaging portion 61, causing the second engaging portion 61 to rotate. After rotating a certain angle, the first engaging portion 21 disengages from the second engaging portion 61. Under the action of the first elastic element, the second engaging portion 61 rotates back in the first direction to a position that restricts the first engaging portion 21 from rotating in the opposite direction (in...). Figure 2 The center is the position of the counter-clockwise rotation.

[0042] In this embodiment, when it is necessary to use the suction device to hold an object with one hand, simply hold the handle 1 with one hand to attach the elastic suction member 4 to the object, and then hook the first pressing part 23 of the tightening handle 2 with the fingers of that hand to rotate it in the direction close to the handle 1 (first direction). The first connecting part 22 of the tightening handle 2 rotates synchronously and drives the elastic suction member 4 to deform inward toward the bottom 32 of the cover 3 through the connecting member 5, so that the elastic suction member 4 sucks up the object. The first locking part 21 of the tightening handle 2 also rotates synchronously until it contacts the second locking part 61 of the switch 6 and drives the second locking part 61 to rotate. After rotating a certain angle, the first locking part 21 will automatically disengage from the second locking part 61. Under the action of the first elastic member, the second locking part 61 will automatically rotate and reset in the first direction to a position that can limit the first locking part 21 from rotating in the opposite direction to the first direction. The first locking part 21 cannot rotate under the interference of the second locking part 61. At this time, the connecting member 5 also keeps the elastic suction member 4 in a concave deformation, thereby maintaining the suction of the object. Therefore, using the suction device of this embodiment, one only needs to hook the first pressing part 23 of the tensioning handle 2 with the finger of the same hand and rotate it in the direction close to the gripping handle 1 (first direction) to automatically lock the tensioning handle 2 with the switch 6, thereby ensuring that the elastic suction member 4 always adheres to the item.

[0043] Furthermore, in this embodiment, the first snap-fit ​​portion 21 includes a first arcuate surface 211 and a first flat surface 212 that are connected to each other; the second snap-fit ​​portion 61 includes a second arcuate surface 611 and a second flat surface 612 that are connected to each other.

[0044] When the first engaging part 21 rotates in the first direction, the first arc-shaped surface 211 slides along the second arc-shaped surface 611 and drives the second engaging part 61 to rotate at a certain angle. After the first arc-shaped surface 211 disengages from the second arc-shaped surface 611, the second engaging part 61 rotates in the first direction to reset until the first plane 212 contacts the second plane 612. When the two planes are in contact, the second engaging part 61 can interfere with the rotation of the first engaging part 21.

[0045] In this embodiment, by adopting the above structural form, the automatic disengagement and automatic locking of the first latching part 21 and the second latching part 61 can be achieved in a simple and reliable manner, which can save costs.

[0046] Furthermore, the suction holder in this embodiment also includes a second elastic member 7 installed between the elastic suction member 4 and the bottom 32, the second elastic member 7 applying an elastic force to the elastic suction member 4 to keep it away from the bottom 32.

[0047] In this embodiment, the second elastic element 7 allows the elastic adsorption member 4 to automatically recover its deformation (from a concave state to a flat state) under the action of the second elastic element 7 after no force is applied to the tightening handle 2, thus automatically releasing the adsorption of the item. That is, when unlocking is required, simply pressing the second pressing part 63 causes the second locking part 61 to rotate in the opposite direction to the first direction, causing the second plane 612 to disengage from the first plane 212. The second locking part 61 no longer interferes with the rotation of the first locking part 21, and the tightening handle 2 no longer applies force to the connecting member 5. Therefore, the second elastic element 7 can restore the elastic adsorption member 4 to its original deformation through its elastic restoring force. Thus, the user only needs to use the finger of the same hand to press the second pressing part 63 of the switch 6 to release the item. Therefore, in this embodiment, the second elastic element 7 allows the user to not only perform the adsorption action with one hand but also release the item with one hand, greatly improving the applicability of the adsorption member.

[0048] Furthermore, in this embodiment, the second elastic element 7 is a compression spring, which is sleeved on the outside of the connecting member 5. In this embodiment, the compression spring sleeved on the connecting member 5 not only makes more efficient use of space, but also prevents the compression spring from shifting and failing.

[0049] Furthermore, in this embodiment, the first connecting part 22 includes a first side plate 221 and a second side plate 222. The first side plate 221 is provided with a first guide groove 2211, and the second side plate 222 is provided with a second guide groove 2221. The first guide groove 2211 and the first guide groove 2211 are inclined to the axis of the connecting member 5. The connecting member 5 is disposed between the first side plate 221 and the second side plate 222, and the connecting member 5 is provided with a first guide part and a second guide part (both shown in the figure). The first guide part is slidably installed in the first guide groove 2211, and the second guide part is slidably installed in the second guide groove 2221.

[0050] In this embodiment, the guide groove and guide part are designed to work together to ensure the efficiency of the tensioning handle 2 in driving the connecting piece 5 to move, thereby ensuring the efficiency of the elastic adsorption piece 4 in deforming and completing the adsorption. It also reduces the weight of the tensioning handle 2 and the overall weight of the suction device, making it easier to use.

[0051] Furthermore, in this embodiment, the first snap-fit ​​portion 21 includes a third side plate 213 and a fourth side plate 214 of the same shape and size. The third side plate 213 is an extension of the first side plate 221, and the fourth side plate 214 is an extension of the second side plate 222.

[0052] In this embodiment, the above-described structure can further reduce the overall weight of the suction device.

[0053] Furthermore, the suction holder in this embodiment also includes a reinforcing piece 8 installed inside the elastic suction member 4 and connected to the connector 5. The reinforcing piece 8 can not only improve the connection strength between the connector 5 and the elastic suction member 4, but also improve the speed at which the elastic suction member 4 deforms. That is, compared with the absence of the reinforcing piece 8, the elastic suction member 4 is more concave for every unit length displacement of the connector 5.

[0054] Furthermore, in this embodiment, the tension handle 2 is an integral structure, and the switch 6 is also an integral structure. The integral structural design can improve the structural strength of both.
