Description

Technical Field

[0001] The utility model discloses a device for disassembling a tire, in particular to a multifunctional professional bicycle tire lever. Background Art

[0002] When a bicycle tire is deflated, it is necessary to pry open the outer tube of the tire and take out the inner tube to repair the inner tube. Existing tire levers usually have a prying head at one end so that they can be inserted between the outer tube of the tire and the wheel rim to pry out the outer tube bead. This tire lever has a very simple structure and can only be used to pry the tire. In practice, when people need to pry the tire, they usually need other tools to meet the needs of repair or replacement in more situations. For example, depending on the different structures, they may need to disassemble the bracket or the wheel frame, but people may not carry other tools with them.

[0003] Therefore, it is necessary to develop a tire lever with more functions that can be used in more tire replacement and repair situations, so as to provide users with a fast, efficient and convenient tire replacement tool. Utility Model Content

[0004] The utility model aims to solve the problems raised in the background technology and designs a multifunctional professional bicycle tire lever.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is a multifunctional professional bicycle tire pry bar, comprising a tire pry bar body, characterized in that the tire pry bar body can be divided into two parts: a handle and a pry head, the handle is integrally formed with a strap groove, a bit slot and a bit mounting hole, and the pry head is integrally formed with a mounting slot, a disassembly buckle and a deflation needle valve; the deflation needle valve is designed and formed with a ejector pin structure.

[0006] Preferably, the bit holder slots are designed to be multiple, with different sizes, and are formed in parallel on the back of the handle in a sunken cavity structure.

[0007] Preferably, each of the bit slots is provided with an elastic buckle to assist in the fixing and installation of the bit.

[0008] Preferably, the bit mounting hole is a hexagonal countersunk hole.

[0009] Preferably, the installation slot is designed to be an open slot structure, and a convex edge extends from the outer edge thereof.

[0010] Preferably, the inner side of the disassembly buckle is a tread prying surface formed in a curved or arc shape, and the outer side is a positioning surface formed with a limiting member.

[0011] Preferably, the tire lever body is also designed with anti-slip texture.

[0012] Compared with the prior art, the advantages of the present invention are: the present invention has the ability to dismantle or install the inner and outer tires of bicycles by rationally designing the prying head; the smooth curved prying surface design of the present invention can avoid scratching the inner tube of the bicycle during operation; and the present invention also integrates a deflation needle valve to effectively deflate the inner tube during replacement so that the user can smoothly remove the inner tube, preventing the inner tube from being difficult to remove or bursting when inflated. In addition, the present invention also has built-in screwdriver bits of different sizes for users to replace commonly used wrenches, so as to perform simple disassembly, assembly and maintenance of bicycles of different models, thereby achieving use in more occasions and on bicycles of different models while eliminating the inconvenience of requiring additional tools.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 4 As shown, the utility model is a multifunctional professional bicycle tire pry bar, which is composed of a handle 11 and a pry head 12 integrally formed, that is, a tire pry bar body 10, the handle 11 is integrally formed with a strap through groove 2, a screwdriver bit slot 5 and a screwdriver bit mounting hole 6, and the pry head 12 is integrally formed with a mounting slot 1, a disassembly buckle 3 and a deflation needle valve 4, wherein the deflation needle valve 4 is designed and formed with a thimble structure, specifically, the deflation needle valve 4 is a thimble cylinder structure formed in a countersunk hole; the handle 11 is also designed with an anti-slip texture 13.

[0018] There are multiple screwdriver bit slots 5 with different sizes, which are formed in parallel on the back of the handle 11 in a countersunk structure. The purpose of this design is to equip the utility model with screwdriver bits of multiple sizes that are commonly used, greatly improving the versatility of the utility model in more occasions and the adaptability between different models of bicycles. It can be extended to explain that each of the screwdriver bit slots 5 is provided with an elastic buckle 7 to assist the screwdriver bit in fixing and installing, and the screwdriver bit is firmly installed through a simple and reasonable structural design. When it is needed, it is removed and inserted into the screwdriver bit mounting hole 6. The screwdriver bit mounting hole 6 is also a hexagonal countersunk hole to securely assemble the screwdriver bit with the same hexagonal design, especially when the handle 11 is rotated to drive the screwdriver bit in the screwdriver bit mounting hole 6 to rotate, to ensure that the screwdriver bit in the screwdriver bit mounting hole 6 will not slip or idle.

[0019] The installation slot 1 is designed and formed in an open slot structure, and a convex edge 100 extends from its outer edge. The function of the convex edge 100 is to position, assist and guide when the user uses the utility model to rotate the tire into the tire groove of the wheel hub. The convex edge 100 is engaged with the inner side of the tire groove, and then presses against the side of the tire that has entered the tire groove. Then, the utility model is rotated and moved along the wheel hub in the direction where part of the tire is still outside the tire groove, so that the tire can be embedded and installed in the tire groove of the wheel hub.

[0020] When disassembling, the disassembly buckle 3 is used. The user needs to first pry out a certain section of the tire through the disassembly buckle 3 to expose the edge of the tire outside the tire groove of the wheel hub, and then the inner side of the disassembly buckle 3, that is, the tread prying surface 300 designed and formed in a curved or arc shape, is inserted and clamped into the interior of the tire, and then the tire prying bar body 10 is rotated to allow the limiting member 301 formed on the positioning surface 302 to enter and clamp into the tire groove of the wheel hub. Similarly, the limiting member 301 also plays a role of positioning, assisting and guiding, and then presses against the side of the tire that has escaped from the tire groove, either counterclockwise or clockwise, and uses the utility model to drive the tire to rotate along the wheel hub for one circle, so that one side of the tire can be completely escaped from the tire groove.

[0021] It is worth mentioning that the utility model has a strap through slot 2 formed on the tire lever body 10, so that the utility model can be conveniently fixed to any part of the bicycle by a strap to be used in an emergency.
