Abstract
The utility model discloses a battery box falling prevention structure of an electric tool, which comprises a chassis and a battery box sleeved on a chassis terminal. A slide rail which can slide relatively is arranged between the chassis terminal and the inner wall of the battery box, the battery box is provided with a falling prevention button, an elastic sheet for resilience is arranged between one end of the button and the wall of the battery box, the other end of the button extends into the battery box and is provided with at least two fasteners, gaps are left between the fasteners and the wall of the battery box, the wall of the chassis is provided with clamp steps corresponding to the fasteners, and the button controls the fasteners to move backwards to deviate from the clamp steps in the gaps. Due to the limiting device with combination of double fasteners and the clamp steps, the connection between the machine chassis and the battery box can not fail even when one fastener is damaged during collision and blundering of the machine, and the machine can operate again only after secondary loading, thereby improving the working efficiency of the user. Moreover, the utility model can prevent the battery box from knocking against the body of the user after falling off during the blundering of the machine, thereby ensuring the use safety of the user.
Description
Technical field
The utility model relates to the disconnecting prevention structure that battery case is connected with electric tool.
Background technology
Direct current electric power tools generally all will be provided as the battery case of its power supply, and battery case is connected with the connected mode of fuselage by symmetrical a pair of hasp during work.Hasp in the above connected mode is very easily thrown off when the machine accidental fall, is damaged, and the battery case that needs the user to pick up to come off is installed with body again, certainly will reduce operating efficiency; In case hasp damages, battery case can't fixed with body, causes the non-transformer power supply, and machine can not be worked.Do not come off so direct current electric power tools just requires body and power supply to have more reliable fixed form to make it fall the back battery case, and reinstall fast, thereby do not reduce operating efficiency, do not lose function of use.
The utility model content
Technical problem to be solved in the utility model just provides a kind of disconnecting prevention structure of power tool battery box; this disconnecting prevention structure makes the fixing reliable of battery case and electric tool; even electric tool falls or is subjected to other greater impacts; still can not cause battery case to come off, the normal use of protection machine and user's safety.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of power tool battery box disconnecting prevention structure, comprise casing and the battery case that is set in the casing end, it is characterized in that: be provided with the railroad that carries out slide relative between described casing end and battery case inwall, described battery case is provided with the anticreep button, be provided with the resilience shell fragment between button one end and battery case wall body, the button other end stretches in the battery case and is provided with at least two hasps, be provided with the gap between described hasp and battery case wall body, described casing wall body is provided with the card rank corresponding with hasp, and described button control snaps over to retreat in the gap and breaks away from the card rank.
As preferably, described railroad comprises the slide rail that cooperates with slideway on slideway on the battery case inwall and the casing outer wall.Make between battery case and casing and locate, and make things convenient for the installation of battery case.
As preferably, the non-joint end of described hasp is an inclined-plane I, and the non-clamping face on described card rank is the inclined-plane II corresponding with described hasp inclined-plane I, is slidingly matched between two inclined-planes.Be convenient to the installation of battery case.
As preferably, described button is provided with a pair of, and is symmetricly set on the battery case wall body.Stability when improving anticreep effect and work.
As preferably, hasp and card rank are equipped with 2～4, effectively guarantee the anticreep effect.
The utility model is owing to adopted technique scheme; realized multiple anti-deprotection to battery case; by two hasps and the stopping means that cooperates of card rank; machine collides with, even damaged inefficacys that be connected that a hasp can not make machine casing and battery case yet, only need secondary loading when staggering along; machine can move once more; improved user's operating efficiency, and the battery case back bump user health that comes off can prevent that machine from staggering along the time, guaranteed that the user's is safe in utilization.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the outside schematic diagram after electric tool and battery case are installed;
Fig. 2 is that electric tool and battery case are installed back anticreep structural representation;
Disconnecting prevention structure schematic diagram when Fig. 3 staggers along for being subjected to external force;
Fig. 4 is the structural representation of button in the utility model.
Embodiment
As shown in Figures 1 to 4, embodiment for the disconnecting prevention structure of the utility model power tool battery box, comprise casing 3 and the battery case 1 that is set in the casing end, be provided with the railroad that is used to carry out slide relative between inwall between described casing 3 ends and battery case, described railroad comprises the slide rail that cooperates with slideway on slideway on the battery case inwall and the casing outer wall, described battery case 1 is provided with anticreep button 2, be provided with resilience shell fragment 23 between button one end and battery case wall body, after button is inwardly pressed into, remove external force and just can utilize the restoring force of shell fragment to make push-button reset; The button other end stretches in the battery case and is provided with two hasps 21, describedly snap over casing and the battery case glide direction is provided with in turn, be provided with gap 4 between described hasp and battery case wall body, described casing wall body is provided with two card rank 31 with snap fit, button control snaps over to retreat in the gap and breaks away from the card rank, after hasp broke away from the card rank, battery case can unload from casing.The non-joint end of described hasp is an inclined-plane I 22, and the non-clamping face on described card rank is to be slidingly matched between II 32, two inclined-planes in inclined-plane corresponding with described hasp inclined-plane I.Described button 2 is provided with a pair of, and is symmetricly set on battery case 1 wall body.
Be the preferred forms of this patent more than, this patent can also be done other conversion, is arranged on the casing 3 such as button 2, and card rank 31 are arranged on the battery case 1.
When battery case is installed, after the slide rail of the casing 3 of body and the slideway on the battery case 1 aligned, body is pushed battery case, as the inclined-plane II on card rank when contacting with hasp inclined-plane I, hasp 21 is the gap 4 between itself and battery case wall body of setbacks afterwards, and casing 3 slips into battery case 1, to position shown in Figure 2, this moment, two hasps 21 on the battery case will be respectively cooperate with card rank 31 on the casing, promptly finished installation, reached dual anti-tripping state.As shown in Figure 3, when external force that machine is staggered along, hasp 21 on the battery case button 2 can come closer under external force, card rank 31 on the casing will lose spacing and outwards move in battery case 1 at this moment, because of external force is generally the moment non-standing, when moving to hasp 21 positions in battery case 1 outside, inboard card rank 31 and the hasp in the outside 21 be spacing can only oppositely to be moved body and can not separate with battery case.Even if the hasp 21 that leans on the battery case inboard on the battery case button 2 is when being subjected to bigger impact broken invalid, battery case button 2 superolateral hasps 21 can also play same spacing anticreep effect, guarantee after a hasp 21 lost efficacy, body still can not separate with battery case, and secondary loads the back machine and still can use.
