Description

Technical Field

[0001] The present application relates to the technical field of wrenches, and in particular to a cover opening wrench. Background Art

[0002] Target materials require very high cleanliness levels. After machining, they must be cleaned and then vacuum-sealed. This cleaning process often requires the use of an environmentally friendly liquid detergent. The bottle cap is typically made of plastic, with ridges circumferentially arranged on the sidewalls. Due to the strong connection between the cap and the bottle, it is difficult to unscrew by hand, especially when hands are wet or sweaty. This makes both installation and removal of the detergent bottle cap difficult. Utility Model Content

[0003] In order to facilitate unscrewing the bottle cap of the detergent, the present application provides a cap opening wrench.

[0004] This application provides a lid opening wrench, which adopts the following technical solution:

[0005] A lid opening wrench comprises an opener head and a handle connected to each other. A clearance hole for the bottle cap to pass through is provided in the opener head. The opener head is provided with a plurality of positioning blocks on the side wall of the clearance hole. The positioning blocks can be respectively inserted between the convex strips on the side wall of the bottle cap.

[0006] By adopting the above technical solution, the bottle cap is passed through the clearance hole, and the locking block is locked between the convex strips of the bottle cap. When the opening head is rotated by the handle, the locking block rotates with the opening head and abuts against the side wall of the convex strip. The handle is continued to be rotated. At this time, the bottle cap can be driven to rotate by the interaction force between the locking block and the convex strip, thereby opening the bottle cap.

[0007] Optionally, the blocking block is a rectangular block.

[0008] By adopting the above technical solution, the design of the rectangular block enables a stable interaction force to be formed between the positioning block and the convex strip of the bottle cap, thereby driving the convex strip to rotate, thereby driving the bottle cap to rotate.

[0009] Optionally, a hanging hole is provided at one end of the handle away from the lid opening head.

[0010] By adopting the above technical solution, the design of the hanging hole allows the cover opening wrench to be easily hung on a wall or other fixed objects, making it easy to carry and store.

[0011] Optionally, the handle includes a first rod, a second rod and a limit assembly, the first rod and the second rod are rotatably connected to each other, the end of the first rod away from the second rod is connected to the opening head, and when the first rod and the second rod are located on the same plane, the limit assembly can limit the rotation of the second rod.

[0012] By adopting the above technical solution, since some detergent bottles have an upward protrusion on the upper surface, when turning the handle, due to the blocking effect of the bottle body, it is necessary to turn it a certain distance, then slide the opener head upward, adjust the position, and then re-insert the opener head for rotation; by turning the flip handle, the interference between the handle and the bottle body can be avoided, the bottle cap can be turned smoothly and continuously, and the convenience of operation is improved.

[0013] Optionally, two supports are provided at one end of the first rod facing the second rod, a rotating shaft is provided between the two supports, and a connecting seat is provided at one end of the second rod facing the first rod, a rotating hole is provided in the connecting seat for the rotating shaft to pass through and rotate.

[0014] By adopting the above technical solution, the connection between the first rod and the second rod is achieved through the support and the rotation axis. This design provides a stable rotation mechanism.

[0015] Optionally, the upper surface of the rotating shaft is a plane, and the connecting seat is provided with a positioning block on the side wall of the rotating hole, and the positioning block has a first positioning surface and a second positioning surface perpendicular to each other. When the first rod and the second rod are located on the same plane, the first positioning surface and the upper surface of the rotating shaft abut against each other, and when the first rod and the second rod are perpendicular, the second positioning surface and the upper surface of the rotating shaft abut against each other.

[0016] By adopting the above technical solution, the cooperation between the positioning block and the rotation axis can limit the rotation range of the second rod. At the same time, when the second rod and the first rod are in a horizontal state or in a mutually perpendicular state, they can provide certain positioning support, thereby improving stability during use.

[0017] Optionally, the limiting assembly includes a limiting sleeve and a positioning member, the limiting sleeve is slidably disposed on the handle, and the positioning member can limit the limiting sleeve from sliding on the handle.

[0018] By adopting the above technical solution, the limiting sleeve is used to stably limit the relative rotation of the first rod and the second rod, and the positioning member can position the limiting sleeve, thereby improving the stability of the operation process.

[0019] Optionally, the positioning member is a positioning bolt, and a threaded hole is provided on the side wall of the limiting sleeve. The positioning bolt can be threadedly connected to pass through the threaded hole and abut against the side wall of the handle.

[0020] By adopting the above technical solution, the limiting sleeve can be locked and unlocked conveniently and quickly by rotating the positioning bolt.

[0021] Optionally, a positioning groove is provided on the surface of the second rod, and the positioning bolt can abut against the bottom wall of the positioning groove after passing through the threaded hole, and the positioning groove extends along the length direction of the second rod.

[0022] By adopting the above technical solution, in conjunction with the positioning groove, the position of the positioning bolt can be guided, and at the same time, the sliding distance of the limit sleeve can also be guided.

[0023] In summary, this application has at least one of the following beneficial effects:

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] Example 1:

[0034] The embodiment of the present application discloses a lid opening wrench. Figure 1 and Figure 2The decapping wrench comprises an interconnected decapping head 1 and a handle 2. A clearance hole 11 for the bottle cap 101 to pass through is coaxially defined on the inner side of the decapping head 1, forming the entire decapping head 1 into a circular shape. Several retaining blocks 12 are fixed to the sidewalls of the clearance hole 11. In this embodiment, four retaining blocks 12 are circumferentially spaced apart. The retaining blocks 12 are preferably rectangular and can be integrally formed with the decapping head 1 to ensure the strength of the connection between them.

[0035] When in use, the bottle cap 101 passes through the clearance hole 11, and the blocking block 12 is blocked between the ridges of the bottle cap 101. When the opener 1 is rotated by the handle 2, the blocking block 12 rotates with the opener 1 and abuts against the side wall of the ridge. The handle 2 is continued to be rotated. At this time, the bottle cap 101 can be driven to rotate by the interaction force between the blocking block 12 and the ridge, thereby opening the bottle cap 101.

[0036] Reference Figure 2 In this embodiment, in order to ensure the strength of the lid opening wrench, the lid opening head 1 and the handle 2 can be made of metal, and preferably stainless steel. The handle 2 is mainly used for gripping and applying force. Therefore, the handle 2 is preferably configured as a rectangular long block structure. The edges where the sides of the handle 2 intersect can be chamfered to make the edges more rounded and convenient to grip. A hanging hole 21 can be further provided at the end of the handle 2 away from the lid head 1. The hanging hole 21 can be configured as a circle to facilitate hanging and storing the lid opening wrench. In other embodiments, the hanging hole 21 can also be configured as a rectangle, an inner hexagon, or the like, so that the hanging hole 21 can also be used for purposes such as unscrewing bolts.

[0037] The implementation principle of the lid opening wrench in the embodiment of the present application is: when using the lid opening wrench, you only need to hold the column handle 2, then align the clearance hole 11 on the lid opening head 1 with the bottle cap 101, move the lid opening wrench downward, so that the bottle cap 101 passes through the clearance hole 11, and at the same time, control the used locking blocks 12 to be stuck between the convex strips of the bottle cap 101, so that the bottle cap 101 can be rotated by turning the handle 2.

[0038] Example 2:

[0039] The difference between the embodiment of the present application and embodiment 1 is that the handle 2 is configured as a rotatable structure; Figure 1 Since some detergent bottles have an upward protrusion on the upper surface, when the handle 2 is rotated, due to the blocking effect of the bottle body, it is necessary to rotate it for a distance, then slide the opener head 1 upward, adjust the position, and then re-insert the opener head 1 for rotation; in this embodiment, by rotating the flip handle 2, the interference between the handle 2 and the bottle body can be avoided, and the bottle cap 101 can be rotated smoothly and continuously, thereby improving the convenience of operation.

[0040] Refer to Figures 3 and Figure 4 In this embodiment, the handle 2 includes a first rod 3, a second rod 4 and a limit assembly 5, wherein the first rod 3 is integrally formed with the outer wall of the cover opening head 1, and the second rod 4 is rotatably connected to the first rod 3 and can be flipped around the width direction of the handle 2 as the central axis; when the first rod 3, the second rod 4 and the cover opening head 1 are in the same plane, the limit member can limit the rotation of the second rod 4. At this time, the cover opening head 1 can be stably rotated by controlling the second rod 4.

[0041] Reference Figure 4 and Figure 5 Specifically, two supports 31 are integrally formed on the end surface of the first rod 3 facing the second rod 4, and a rotating shaft 32 is fixed between the two supports 31, and the length direction of the rotating shaft 32 is parallel to the width direction of the handle 2; the second rod 4 is integrally formed with a connecting seat 41 facing the direction of the first rod 3, and the connecting seat 41 can be snapped and rotated between the two supports 31, and a rotating hole 42 is opened on the connecting seat 41 for the rotating shaft 32 to pass through and rotate; thereby, the connection between the first rod 3 and the second rod 4 can be realized.

[0042] Furthermore, the upper surface of the rotating shaft 32 is a rectangular plane, and correspondingly, the cross-section of the rotating shaft 32 is semicircular; the rotating hole 42 is a circular hole, and a positioning block 43 is provided on the inner wall of the connecting seat 41 and the rotating hole 42. The positioning block 43 has a first plane and a second plane perpendicular to each other. When the first rod 3 and the second rod 4 are located on the same plane, the first positioning surface 431 abuts against the upper surface of the rotating shaft 32. When the first rod 3 and the second rod 4 are perpendicular, the second positioning surface 432 abuts against the upper surface of the rotating shaft 32. Through the cooperation of the first plane, the second plane and the upper surface of the rotating shaft 32, the first rod 3 and the second rod 4 can be more stably in the same straight line or in a mutually perpendicular state; that is, the rotation of the second rod 4 can be positioned, and the stability of controlling the rotation of the second rod 4 can also be improved.

[0043] Reference Figure 3 and Figure 4 In this embodiment, the limiting assembly 5 includes a limiting sleeve 51 and a positioning member 52. The limiting sleeve 51 has a "U"-shaped cross-section and is slidably sleeved on the handle 2. When the two ends of the limiting sleeve 51 are respectively located on the first rod 3 and the second rod 4, the second rod 4 can be restricted from rotating, thereby improving the stability when the second rod 4 is rotated; when the limiting sleeve 51 slides toward the second rod 4 and separates from the first rod 3, the second rod 4 can be rotated so that the first rod 3 and the second rod 4 are at 90 degrees. At this time, when the first rod 3 is driven by the second rod 4 to rotate the capping head 1, interference with the raised part of the bottle body can be avoided, and the bottle cap 101 can be continuously rotated.

[0044] The positioning member 52 is used to limit the sliding of the limiting sleeve 51. Specifically, the positioning member 52 is preferably set to a positioning bolt 521. A threaded hole 511 is opened on the side wall of the limiting sleeve 51. After the cylindrical part of the positioning bolt 521 is threadedly connected and passes through the threaded hole 511, the end is pressed against the side wall of the second rod 4, so that the sliding of the limiting sleeve 51 can be limited by the interaction force between the positioning bolt 521 and the second rod 4.

[0045] Reference Figure 4 and Figure 5 Furthermore, a positioning groove 44 is provided on the surface of the second rod 4, and the cylindrical portion of the positioning bolt 521 passes through the threaded hole 511 or, and its end portion can be inserted into the positioning groove 44, and the positioning groove 44 extends along the length direction of the second rod 4; when the positioning bolt 521 is rotated, the end face of the positioning bolt 521 is pressed against the bottom wall of the positioning groove 44, which can limit the rotation of the limiting sleeve 51; at the same time, when the limiting sleeve 51 slides, it drives the positioning bolt 521 to slide in the positioning groove 44, which can limit the sliding distance of the limiting sleeve 51.

[0046] The implementation principle of the lid opening wrench in the embodiment of the present application is as follows: when the bottle body to be opened has a protrusion; the reverse positioning bolt 521 can be rotated first to unlock the limit sleeve 51, and the limit sleeve 51 can be slid toward the second rod 4 and fixed in place with the positioning bolt 521; then the second rod 4 is rotated to above the first rod 3, that is, perpendicular to the first rod 3, and the bottle cap 101 can be continuously rotated by rotating the second rod 4, thereby opening the bottle cap 101.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
