Specific implementation mode

For the technology contents of the utility model, construction feature, the effect realized is described in detail, below in conjunction with embodiment And attached drawing is coordinated to be explained in detail.

As shown in Figure 1 and Figure 2, pull rod 100 of the utility model with safety lock includes telescopic rod 1, handle 2, button 3 and peace Full lock set 4, the telescopic rod 1 are telescopically set to babinet outward, and the middle part of the handle 2 is connected to the telescopic rod 1 Upper end, the button 3 are set in the through-hole 2a at the middle part of the handle 2；The safe lock set 4 includes push button 41 and locking Part 42, the locking piece 42 are slidingly arranged in the handle 2, and the push button 41 is slidingly arranged at the one of the handle 2 The surface at end, and be fixedly connected with the locking piece 42 to push 42 clamping of the locking piece or discharge the button 3.

It please refers to again shown in Fig. 2 and Fig. 3, specifically, the locking piece 42 offers the first elongated hole 42a, and described first The length of elongated hole 42a is more than the length of the button 3, and the button 3 is set in the first elongated hole 42a, described to press Three side horizontals of button 3 extend holding section 31, three sides corresponding with the holding section 31 of the first elongated hole 42a Edge forms abutting portion 42b, and when the locking piece 42 is slided close to the button 3, the abutting portion 42b slides into the holding section 31 lower section, the abutting portion 42b contact at the holding section 31 and stop that the holding section 31 moves down, and the locking piece 42 is slided When the dynamic separate button 3, the abutting portion 42b is detached from the holding section 31.Using the holding section 31 and abutting portion 42b, It can stop 3 slide downward of the button, to realize to it into line-locked purpose, prevent accidental operation.

Fig. 2, Fig. 3 and Fig. 4 are please referred to, the sliding groove 21 along 42 glide direction of the locking piece is offered in the handle 2, The locking piece 42 is slidingly arranged at equipped with slipping rib 42c, the slipping rib 42c in the sliding groove 21.The cunning is set The cooperation of dynamic slot 21 and slipping rib 42c, can enable the locking piece 42 swimmingly translate, and ensure what safe lock set 4 worked Stability.Guide post 22 is equipped in the handle 2, the locking piece 42 is equipped with the pilot hole 42d along glide direction, the guiding Hole 42d is slidably matched with the guide post 22.The guide post 22 and pilot hole 42d coordinates, and can prevent the locking Part 42 shifts during translation, is conducive to the accuracy for improving the work of safe lock set 4.

Again as shown in Figures 1 and 2, the surface of the handle 2 is equipped with the storage tank 23 to lower recess, and the push button 41 slides Ground is set to inside and the locking piece 42 that in the storage tank 23 and lower end stretches into the handle 2 across the storage tank 23 It is fixed.The storage tank 23, which is arranged, can make the flush on surface and handle 2 of push button 41, and handle 2 is on the one hand avoided to occur On the other hand maloperation improves the comfort of gripping handle 2.

In summary, the operation principle of pull rod of the utility model with safety lock is described below, it is as follows：

As shown in figure 4, when the button 3 is in release the lock state, the push button 41 is in the storage tank 23 far from institute One end of button 3 is stated, at this point, the abutting portion 42b of the locking piece 42, far from the holding section 31, button 3 described in pressable makes The button 3 touches locking mechanism, and then makes the locking mechanism to 1 release the lock of the telescopic rod.

As shown in figure 5, when the telescopic rod 1 is in and stretches out use state, the push button 41 is pushed, the push button 41 is made In the storage tank 23 close to one end of the button 3, at this moment, it is described that the movement of the locking piece 42 makes abutting portion 42b be located at The lower section of holding section 31, the abutting portion 42b stop that the holding section 31 moves down, and therefore, the button 3 cannot be pressed downwards Pressure, to make the button 3 that can not be contacted with locking mechanism, the locking mechanism can then ensure the locking shape to telescopic rod 1 State.

Compared with prior art, since the utility model on the handle 2 by being arranged a locking piece 42 and a push button 41, it pushes locking piece 42 to slide using push button 41, and then make 42 clamping of locking piece or the release button 3, is prevented to reach Or the purpose that the release button 3 unlocks telescopic rod 1, therefore, when in use, lock safe to use can accidentally be grasped to avoid hand Make, prevents pull rod from surprisingly shrinking, effectively improve the safety used；When not making, it is only necessary to push the push button 41 open, you can to pressing Button 3 unlocks, and the button 3 can carry out release the lock by locking mechanism to pull rod, easy to operate, easy to use.

The structure and working principle of locking mechanism involved by the pull rod 100 with safety lock of the utility model is this Known to the those of ordinary skill of field, no longer it is described in detail herein.

Above disclosed is only the preferred embodiments of the utility model, cannot limit the utility model with this certainly Interest field, therefore equivalent variations made according to the patent scope of the utility model still fall within the utility model and are covered Range.
