Description

Technical Field

[0001] This utility model relates to the field of heated handlebar technology, and in particular, to a heat-insulating and heated handlebar. Background Technology

[0002] Currently, Chinese patent application CN114013548A discloses a motorcycle heated grip sleeve and its processing method, including an inner core, an outer sleeve, and a control switch. The inner core is wound with a heating wire, and the outer sleeve is installed on the outside of the inner core. It also includes an indicator light, and the control switch is installed on the outer sleeve. The control switch has a power input terminal, a first control terminal, and a second control terminal. The power input terminal is electrically connected to the motorcycle's power supply. The first control terminal is electrically connected to the heating wire and is used to control the on / off state of the heating wire. The second control terminal is electrically connected to the indicator light and is used to control the color change of the indicator light.

[0003] Because the control switch is mounted on the outer cover, there is only one wire between the grip and the motorcycle's power supply. This wire is only used to connect the positive and negative terminals of the motorcycle's power supply, resulting in fewer wires.

[0004] However, in this type of motorcycle heated grip sleeve and its manufacturing method, when the heating wire heats up, most of the heat is transferred to the interior of the sleeve core, that is, to the hollow part of the sleeve core, resulting in a large amount of heat loss. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a heat-insulating and heating handle cover to reduce heat loss.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a heat-insulating and heating sleeve, including an inner core, an outer sleeve, a heating wire, and a heat insulation sleeve, wherein the heat insulation sleeve is fitted on the inner core, the outer sleeve is fitted on the heat insulation sleeve, and the heating wire is disposed on the side of the heat insulation sleeve facing the outer sleeve.

[0007] To achieve the above technical solution, when the heating wire is energized, it generates heat. Through the heat insulation effect of the heat insulation sleeve, the heat is transferred to the outer sleeve. When the hand is held on the outer sleeve, it can generate sufficient heating effect on the hand, thereby reducing heat loss and improving heat utilization.

[0008] As a preferred embodiment of this utility model, the outer wall of the heat insulation sleeve is provided with a spiral groove for embedding a heating wire, and the spiral groove is arranged along the length direction of the heat insulation sleeve.

[0009] By implementing the above technical solution, the connection between the heating wire and the heat insulation sleeve is tighter, and the heating wire is less likely to move on the heat insulation sleeve, so as to prevent the heating wire from being damaged.

[0010] As a preferred embodiment of this utility model, the heat insulation sleeve is provided with a positioning hole, the positioning hole connecting the inner wall and the outer wall of the heat insulation sleeve, and a positioning post is fixedly connected to the outer wall of the inner core of the sleeve, the positioning post passing through the positioning hole.

[0011] To achieve the above technical solution, the inner core of the sleeve is inserted into the heat insulation sleeve, and the positioning pin is inserted into the positioning hole, so that the connection between the heat insulation sleeve and the inner core of the sleeve is tighter and less prone to relative slippage.

[0012] As a preferred embodiment of this utility model, an auxiliary recess is provided on the inner wall of the heat insulation sleeve, and an auxiliary post is fixedly connected to the outer wall of the inner core of the sleeve, with the auxiliary post embedded in the auxiliary recess.

[0013] To achieve the above technical solution, the heat insulation sleeve is fitted onto the inner core, and the auxiliary post is embedded in the auxiliary recess, making the connection between the heat insulation sleeve and the inner core tighter and less prone to relative slippage.

[0014] As a preferred embodiment of this utility model, the outer wall of the heat insulation sleeve is fixedly connected with anti-slip protrusions for abutting against the inner wall of the outer sleeve, and the anti-slip protrusions correspond to the auxiliary concave holes.

[0015] To achieve the above technical solution, the anti-slip protrusions improve the connection stability between the outer jacket and the heat insulation sleeve. At the same time, since the anti-slip protrusions correspond to the auxiliary recesses, the auxiliary recesses have a certain structural strength, making the connection between the outer jacket and the heat insulation sleeve more stable.

[0016] As a preferred embodiment of this utility model, the end of the heat insulation sleeve is provided with a positioning groove, and a limiting protrusion is fixedly connected to the outer wall of the inner core of the sleeve, the limiting protrusion corresponding to the positioning groove.

[0017] The above technical solution makes it less likely for the inner cores of the insulation box to rotate relative to each other.

[0018] As a preferred embodiment of this utility model, the end of the outer jacket is provided with a receiving groove, and a control switch is fixedly connected in the receiving groove. The control switch is used to control the heating wire to turn on and off.

[0019] The above technical solution allows for easy control of the heating wire's on / off state via a control switch while holding the jacket, thus improving ease of use.

[0020] As a preferred embodiment of this utility model, the outer wall of the jacket is provided with anti-slip grooves, which are arranged along the axial direction of the jacket.

[0021] The above technical solution makes the connection between the hand and the coat more stable when holding the coat.

[0022] As a preferred embodiment of this utility model, an anti-slip strip is fixedly connected to the outer wall of the outer jacket, and the anti-slip strip is arranged along the axial direction of the outer jacket.

[0023] The above technical solution makes the connection between the hand and the coat more stable when holding the coat. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0032] A heat-insulating and heating sleeve includes an inner core 1, an outer sleeve 2, a heating wire 3, and a heat-insulating sleeve 4 made of modified PVC. A spiral groove 41 for embedding the heating wire 3 is formed on the outer wall of the heat-insulating sleeve 4, and the heating wire 3 is embedded in the spiral groove 41 in a spiral manner. The spiral grooves 41 are evenly distributed along the length of the heat-insulating sleeve 4. The heat-insulating sleeve 4 is fitted over the inner core 1, and the outer sleeve 2 is fitted over the outer side of the heat-insulating sleeve 4.

[0033] A positioning hole 51 is provided on the heat insulation sleeve 4, which connects the inner wall and the outer wall of the heat insulation sleeve 4. Multiple positioning holes 51 are evenly arranged along the length of the heat insulation sleeve 4. The distance between two positioning holes 51 is equal to the pitch of the spiral groove 41.

[0034] A positioning post 52 is fixedly connected to the outer wall of the inner core 1. The positioning post 52 passes through the positioning hole 51, and each positioning hole 51 corresponds to one positioning post 52.

[0035] Auxiliary recesses 61 are formed on the inner wall of the heat insulation sleeve 4, and multiple auxiliary recesses 61 are evenly arranged along the length of the heat insulation sleeve 4. The distance between two adjacent auxiliary recesses 61 is equal to the pitch of the spiral groove 41.

[0036] An auxiliary post 62 is fixedly connected to the outer wall of the inner core 1. The auxiliary post 62 is used to be embedded in the auxiliary recess 61, and one auxiliary post 62 corresponds to one auxiliary recess 61.

[0037] An anti-slip protrusion 7 is fixedly connected to the outer wall of the heat insulation sleeve 4 to abut against the inner wall of the outer sleeve 2. The anti-slip protrusion 7 corresponds to the auxiliary recess 61. When the auxiliary post 62 is embedded in the auxiliary recess 61, the structural strength of the anti-slip protrusion 7 can be improved, thereby increasing the friction between the heat insulation sleeve 4 and the outer sleeve 2 and improving the structural stability.

[0038] A positioning groove 81 is provided at the end of the heat insulation sleeve 4, and a limiting protrusion 82 is fixedly connected to the outer wall of the inner core 1 of the sleeve, with the limiting protrusion 82 corresponding to the positioning groove 81.

[0039] A receiving groove 9 is provided at one end of the outer jacket 2, located at the end of the outer jacket 2 away from the positioning groove 81. A control switch 91 is fixedly connected inside the receiving groove 9, and the control switch 91 is used to control the on and off of the heating wire 3. The control switch 91 is prior art.

[0040] Anti-slip grooves 100 are formed on the outer wall of the outer jacket 2, and the anti-slip grooves 100 are arranged along the axial direction of the outer jacket 2. The anti-slip grooves 100 can be elongated, L-shaped, or Y-shaped.

[0041] Anti-slip strips 101 are fixedly connected to the outer wall of the outer jacket 2, and the anti-slip strips 101 are arranged along the axial direction of the outer jacket 2.

[0042] Control switch 91 energizes the heating wire 3, causing it to heat up. Through the insulation of the heat-insulating sleeve 4, most of the heat is transferred towards the outer sleeve 2. When the hand is held on the outer sleeve 2, it receives sufficient heating, thus reducing heat loss and improving heat utilization.

[0043] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
