Description

Technical Field

[0001] The invention relates to the technical field of battery replacement, in particular to a battery compartment disassembly and assembly structure of a portable submersible pump for refueling. Background Art

[0002] As people's living standards continue to improve, vehicles have become an indispensable means of transportation for people; at present, when driving vehicles in extreme areas such as outdoor construction sites and deserts, since these extreme areas are relatively remote, cars are often far away from gas stations and vehicles need to be transported over long distances. These extreme areas are not convenient for refueling, and car owners often need to prepare their own oil storage barrels and refueling pumps to facilitate temporary refueling when the vehicle is out of oil. The existing refueling pumps have the defects of complex structure and inconvenient use.

[0003] Moreover, the mouth of the existing oil barrel is often tilted for the purpose of convenient dumping, and the gas pump is inserted into the oil barrel from the top to the bottom. For easy operation, the control switch needs to be set on the top of the control body. For example, the portable gas pump disclosed in the Chinese patent authorization announcement number CN 217025334 U discloses a horizontal pump. Since the control body is provided with a control switch on one side of the top, and a battery slot is provided on the other side to accommodate the battery for powering the gas pump, the control body is arranged horizontally and inverted as a whole, which leads to a large volume of the control body; and when replacing the battery, it is necessary to slide the clamped battery cover with force to replace the battery, which is quite laborious. In addition, due to the tilted design of the mouth of the barrel, the horizontal pump needs to be screwed and fixed with the oil tank cover and the oil barrel, which still has certain inconveniences in use. At the same time, embodiment 2 of the scheme also discloses a vertical pump, in which the control body is arranged vertically, the control switch is arranged on the top of the control body, and a vertical battery slot is arranged in the control body below the control switch. The batteries in the vertical battery slot are two sections distributed up and down, so that the lateral volume of the product can be smaller, but it is more difficult to replace the battery. First, it is still necessary to remove the battery cover with great effort, and then after taking out the upper battery, the entire product often needs to be turned upside down to pour out the lower battery. However, because the oil guide tube is inserted into the oil barrel and is stained with liquid, once the oil guide tube is pulled out obliquely away from the barrel mouth, some oil will drip and easily splash onto the user, not to mention that after the control body is turned upside down, the oil will flow along the oil guide tube and contaminate the hands and the control body. Therefore, the vertical pump has the problem of difficult battery replacement and easy pollution. Summary of the invention

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] like Figures 1 to 7As shown, the battery compartment disassembly and assembly structure of a portable submersible pump for refueling in this embodiment includes a control body 1, a first oil guide pipe 2, a second oil guide pipe 3, a pump body 4 and an oil gun 5; the control body 1 is connected to the pump body 4 through the first oil guide pipe 2, and is connected to the oil gun 5 through the second oil guide pipe 3; the control body 1 is used to control the operation of the pump body 4 and to deliver the liquid sucked by the pump body 4 to the oil gun 5. Figure 8 Therefore, when using the submersible pump for refueling, the pump body 4 and the first oil guide pipe 2 can be inserted into the barrel mouth 61 of the oil barrel 6, so that the pump body 4 extends into the oil, and the pump body 4 is controlled by the control body 1 to suck the oil in the oil barrel 6, so that the oil can flow through the first oil guide pipe 2 to the second oil guide pipe 3 and finally flow out from the oil gun 5, which is convenient for portable refueling of vehicles, etc.

[0020] The main improvement of this embodiment is in the control body 1 , which is provided with a detachable battery compartment 7 .

[0021] The control body 1 includes a connecting portion 11 and a mounting portion 12 . The bottom of the connecting portion 11 is connected to the first oil pipe 2 . The side of the connecting portion 11 can be connected to the second oil pipe 3 , and the first oil pipe 2 and the second oil pipe 3 can be connected to each other inside the connecting portion 11 .

[0022] The mounting portion 12 is arranged at the top of the front side of the connecting portion 11, and an mounting space 13 for mounting the battery compartment 7 is formed between the bottom of the mounting portion 12 and the front side of the connecting portion 11; a control board 14 for controlling the pump body 4 is arranged in the control body 1, and a connecting component 141 electrically connected to the control board 14 is provided at the bottom of the mounting portion 12; the top of the battery compartment 7 is open, and the battery compartment 7 contains a battery 71; the battery compartment 7 can be moved forward and backward and can be clamped up and down in the mounting space 13 to electrically connect the battery 71 to the connecting component 141.

[0023] By providing a detachable battery compartment 7, not only can the height of the control body 11 of the vertical pump structure be lowered, and the center of gravity of the control body 11 be lowered; the battery 71 can also be conveniently replaced without the need to lift or invert the first oil guide pipe 2 outward obliquely, thereby preventing oil contamination; and considering that a control switch 142 needs to be provided on the top of the control body 1, and the lower part of the connecting portion 11 needs to be inserted into the inclined barrel mouth 61, the present embodiment arranges the battery compartment 7 between the mounting portion 12 of the control body 1 and the inclined barrel mouth 61, and arranges it to cooperate with the control body 1 to move forward and backward and to be engaged up and down. When the refueling submersible pump is obliquely inserted into the barrel mouth 61, the battery compartment 7 can first be moved obliquely downward for a distance, and then be disassembled obliquely parallel to the inclined surface where the barrel mouth 61 is located, without the need to move other components, which can solve the defect that the distance between the control body 1 and the barrel mouth 61 is too small and the battery compartment 7 cannot be directly moved obliquely downward for removal, thereby ensuring that the refueling submersible pump does not need to be lifted, and effectively ensuring that oil contamination will not be caused.

[0024] Specifically, Figures 2 to 4 As shown, a card slot 15 is provided on the front side of the connecting portion 11 of this embodiment, and the card slot 15 includes a lower inlet 151 and an upper card slot 152, and an elastic card connection component 8 is provided in the card slot 152; a card block 72 protrudes from the rear side of the battery compartment 7, and a card hole 721 for the elastic card connection component 8 to be engaged is provided in the card block 72; the card block 72 can enter the card slot 15 along the inlet 151 and move up and down in the card slot 15; when the card block 72 moves up to the card slot 152, it is restricted from moving outward by the card slot 152 and restricted from moving downward by the elastic card connection component 8.

[0025] Therefore, see Figures 5 to 7 When installing, load the battery 71 into the battery compartment 7, move the battery compartment 7 from front to back, insert the rear side block 72 of the battery compartment 7 into the entrance 151 of the slot 15, and then move the battery compartment 7 upward so that the block 72 can be moved upward into the slot 152, so that the top of each battery 71 is electrically connected to the connecting component 141, and at the same time, the elastic clamping component 8 can be clamped into the clamping hole 721 to limit the falling of the battery compartment 7, and the block 72 of the battery compartment 7 is limited by the slot 152 and cannot move forward and outward, finally realizing the installation and fixation of the battery compartment 7; when disassembling, the upper and lower movement limit of the battery compartment 7 can be released by controlling the elastic clamping component 8 to withdraw from the clamping hole 721, so that the battery compartment 7 can be moved down from the slot 152 to the entrance 151, and then the battery compartment 7 is completely taken out from the back to the front to replace the battery 71.

[0026] like Figure 2 and Figure 3 As shown, in this embodiment, the bayonet 152 includes two relatively protruding clamping edges 153 disposed on both sides of the bayonet 152; and the two sides of the clamp block 72 are provided with clamping grooves 722 for the clamping edges 153 to slide up and down, thereby achieving a stable front and rear limiting effect.

[0027] In this embodiment, the elastic clamping assembly 8 can adopt the following structure to achieve the function of extending into or withdrawing from the clamping hole 721. Of course, other methods can also be adopted, and the present invention is not limited to this.

[0028] like Figure 4 As shown, the elastic clamping assembly 8 may include a sliding member 81 , an elastic member 82 and a pressing member 83 .

[0029] The sliding member 81 is slidably connected front and back and is limitedly installed on the rear side of the bayonet 152. The front side of the sliding member 81 has a forward-protruding clamping portion 811, and the bottom of the clamping portion 811 is a slope 812 that is higher in the front and lower in the back. In this embodiment, two clamping portions 811 are provided at intervals on the left and right, and the clamping block 72 has two clamping holes 721 at intervals on the left and right to improve the limiting and fixing effect.

[0030] The sliding member 81 has an inclined guide block 813 on the rear side, and the inclined guide block 813 has an inclined guide surface 814; the elastic member 82 is located on the rear side of the sliding member 81, and is used to provide elastic force for the sliding member 81 to slide forward; the pressing member 83 is slidably connected to the connecting portion 11 of the control body 1, and the outer end of the pressing member 83 is a pressing portion 831 extending out of the side wall of the control body 1, and the inner end is a contact portion 832 that cooperates with the inclined guide surface 814. The pressing portion 831 is pressed to drive the contact portion 832 to press against the inclined guide surface 814 and drive the sliding member 81 to move backward.

[0031] Thus, when the block 72 of the battery compartment 7 moves upward from the entrance 151 to the bayonet 152, the upper end of the block 72 can contact the bottom inclined surface 812 of the clamping portion 811 to guide the sliding member 81 to move back and squeeze the elastic member 82, until the block 72 moves up to align the clamping hole 721 with the clamping portion 811, and the elastic member 82 is reset to make the clamping portion 811 forwardly clamped into the clamping hole 721, so as to achieve upper and lower limit matching; and when the battery compartment 7 needs to be disassembled, it is only necessary to press the pressing portion 831 exposed on the side wall of the control body 1 to drive the abutting portion 832 to press the inclined guide surface 814, thereby controlling the sliding member 81 to move backward to squeeze the elastic member 82 and exit the clamping hole 721, so that the battery compartment 7 can freely fall away from the bayonet 152, and after releasing the pressing portion 831, the sliding member 81 can be reset forward under the action of the elastic member 82, so as to facilitate the subsequent installation operation. Thus, the entire process of replacing the battery 71 is labor-saving and convenient.

[0032] Furthermore, the elastic snap-fit ​​assembly 8 also includes a sliding column 84 installed and fixed on the rear side of the bayonet 152; and the sliding member 81 is provided with two inclined guide blocks 813 that are spaced left and right and are outwardly expanded, and the opposite surfaces of the two inclined guide blocks 813 are the inclined guide surfaces 814; the sliding member 81 has a through hole 815 between the two inclined guide blocks 813 for the sliding column 84 to pass through, and the front end of the sliding column 84 is limited to the front side of the sliding member 81, thereby facilitating the assembly and cooperation of the elastic snap-fit ​​assembly 8, and the sliding member 81 can be slidably installed on the sliding column 84; and the elastic member 82 can be a spring sleeved on the sliding column 84 to resist the sliding member 81 from sliding along the sliding column 84.

[0033] There are two pressing members 83, which are arranged on the left and right sides in alignment with the two inclined guide surfaces 814, and each has a pressing portion 831 extending out from the left and right side walls of the control body 1. By providing two pressing members 83, when in use, the base of the thumb of one hand can correspond to the front side of the battery compartment 7, and then the thumb and index finger can press the pressing portions 831 on the left and right sides of the body respectively, and the pressing portion 831 can be pressed conveniently and labor-savingly to drive the sliding member 81 to move backward to release the limit of the block 72. After the battery compartment 7 falls, it can be held and taken out with the palm of the hand, and the disassembly and assembly are relatively convenient and fast.

[0034] In this embodiment, the control board 14 is installed in the installation part 12, and the control board 14 can be electrically connected to the pump body 4 through an oil-resistant wire 143 (schematically shown in the figure); the oil-resistant wire 143 can enter the connecting part 11 through the installation part 12 and then extend into the first oil guide pipe 2 and then be connected to the pump body 4.

[0035] A control switch 142 electrically connected to the control board 14 may be provided at the top of the mounting portion 12 for easy operation; and a ring handle 121 may be provided at the front end of the mounting portion 12 for easy lifting after use, and may also be used for temporarily hanging the oil gun 5.

[0036] See also Figure 8 In this embodiment, the bottom of the connecting portion 11 has a tapered clamping sleeve 111 with a tapered lower end, and the top of the first oil guide pipe 2 is installed in the tapered clamping sleeve 111; the outer wall of the tapered clamping sleeve 111 has a clamping pattern; the tapered clamping sleeve 111 can be used to tightly fit and fix the control body 1 at the barrel mouth 61 after the pump body 4 and the first oil guide pipe 2 are inserted into the oil barrel 6. The installation and fixation is labor-saving and convenient, and there is no need to perform laborious screw rotation operations at the barrel mouth 61 with limited space.

[0037] Moreover, the top of the first oil guide pipe 2 and the conical clamping sleeve 111 are detachably matched, so that the first oil guide pipe 2 of different lengths can be replaced according to the oil drums 6 of different depths.

[0038] The left side wall or the right side wall of the connecting portion 11 may be provided with at least one hook 112. Figure 2 Specifically, in this embodiment, the left side of the connecting portion 11 is connected to the second oil guide pipe 3, and the second oil guide pipe 3 can be a corrugated tube, and the right side wall of the connecting portion 11 can be provided with a hook 112, which can also be used to hang the oil gun 5 to prevent the oil gun 5 from being directly placed on the ground and contaminated.

[0039] like Figure 4 As shown, in this embodiment, the control body 1 includes a left shell 16 and a right shell 17, and the connecting portion 11 and the mounting portion 12 are respectively composed of a left half and a right half on the left shell 16 and the right shell 17, and the left shell 16 and the right shell 17 are connected by left and right locking screws, which is convenient for installing the elastic snap-on assembly 8 and the first oil guide pipe 2 and the second oil guide pipe 3. In addition, due to the independently arranged battery compartment 7, the left shell 16 and the right shell 17 themselves do not need to consider the battery compartment 7, and there is enough space to lock the screws to ensure structural stability.

[0040] For example Figure 2 and Figure 7As shown, a rotating support piece 18 is hingedly connected to the front side of the bottom of the connecting portion 11, and the rotating support piece 18 can be rotated to the bottom of the battery compartment 7 to support the battery compartment 7. Specifically, two recessed points 73 arranged at intervals can be provided at the bottom of the battery compartment 7; the rotating support piece 18 is arranged on the left and right, and a convex point 181 for positioning at the recessed point 73 is provided on the rotating support piece 18. In this way, it can be ensured that the rotating support piece 18 is rotated in place, and support is provided, which plays a role of insurance and can prevent the battery compartment 7 from accidentally falling out.

[0041] like Figure 4 and Figure 7 As shown, in this embodiment, the bottom of the battery compartment 7 has a conductive sheet 74, and the battery compartment 7 has front and rear batteries 71, the front and rear batteries 71 have opposite polarities and are mutually conductive by the conductive sheet 74; four batteries 71 are shown in the figure, the positive poles of the rear two batteries 71 face upward, and the negative poles of the front two batteries 71 face upward; the corresponding connecting component 141 includes front and rear connecting spring sheets 1411 and connecting protrusions 1412, which are respectively conductively matched with the positive and negative poles of the battery 71.
